The clamping ring is usually required to be additionally arranged between the disc spring base and the disc spring set so that the disc spring set has a certain pretightening force before energy storage.

When the disc spring hydraulic energy storage mechanism is assembled, the clamping ring is clamped in the clamping groove on the supporting cylinder in a manual assembly mode. An operator firstly fixedly places the disc spring hydraulic energy storage mechanism on the disc spring snap ring assembly device disclosed by the utility model with the authority publication number of CN202726450U, and presses the end face of the working cylinder of the disc spring hydraulic energy storage mechanism so as to enable the disc spring group to be compressed and deformed. At the moment, the supporting cylinder inserted in the center of the disc spring set can expose the clamping groove for clamping the clamping ring, so that an operator can clamp the two half clamping rings into the clamping groove. After clamping is completed, the pressure on the working cylinder is removed so that the disc spring group rebounds until the wedge surface of the disc spring base is in a state of being attached to the wedge surface of the clamping ring, and the whole clamping ring assembly process is completed.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent.

The scheme principle of the automatic clamp ring assembly device for the disc spring hydraulic energy storage mechanism is as follows:

an automated assembly of disc spring hydraulic energy storage mechanism snap rings as shown in fig. 3-6 is used to assemble snap ring 26 shown in fig. 2 to the disc spring hydraulic energy storage mechanism shown in fig. 1. The automatic assembling device for the disc spring hydraulic energy storage mechanism clamping ring comprises a base 21. The base 21 is provided with the positioning support seat 3 for positioning the disc spring base 25 for placing the disc spring hydraulic energy storage mechanism, so that the disc spring hydraulic energy storage mechanism can be stably placed on the base 21 through positioning cooperation of the positioning support seat 3 and the disc spring base 25, and therefore the disc spring hydraulic energy storage mechanism has good loading and pressure bearing capacity. After the positioning support seat 3 is positioned and placed on the disc spring base 25 of the disc spring hydraulic energy storage mechanism, certain pressure is applied to the cylinder body of the working cylinder 22 of the disc spring hydraulic energy storage mechanism, so that the cylinder body moves relative to the disc spring base 25, and meanwhile, the disc spring group 23 is compressed, so that the mounting groove of the clamping ring 26 on the disc spring hydraulic energy storage mechanism is exposed. For this purpose, the positioning support 3 is provided with a central passage so that the positioning support 3 can avoid the movement path of the cylinder when the cylinder moves, so that the cylinder can be completely moved to the mounting position of the snap ring 26. The snap ring 26 is specifically a left-right split structure and comprises two semicircular-arc-shaped sheet bodies. The base 21 is correspondingly provided with a pair of snap ring mounting seats 1 so as to respectively bear the sheet bodies. The snap ring mounting seats 1 are provided with positioning and mounting structures for positioning and mounting the snap rings 26, and the paired snap ring mounting seats 1 are provided with clamping driving mechanisms for driving the snap ring mounting seats 1 to move oppositely and reversely. Correspondingly, the lower side of the positioning support seat 3 is provided with an avoidance channel for the paired snap ring mounting seats 1 to radially pass through along the upper snap rings 26. 7-10, when the cylinder body is pressed to the installation position, the clamping ring installation seat 1 is driven by the clamping driving mechanism to approach the disc spring hydraulic energy storage mechanism, and the clamping ring 26 on the clamping ring installation seat is sent into the clamping ring 26 installation groove on the disc spring hydraulic energy storage mechanism. In this embodiment, the cylinder body of the working cylinder 22 of the disc spring hydraulic energy storage mechanism specifically includes a cylinder body and a support cylinder 24 fixedly assembled at one end of the cylinder body toward the bottom side of the disc spring. A snap ring 26 mounting groove into which the snap groove is snapped is provided on the support cylinder 24. When the cylinder body moves to the position where the mounting groove of the clamping ring 26 on the supporting cylinder 24 is flush with the clamping ring 26 on the clamping ring mounting seat 1, the current position of the cylinder body is the mounting position of the clamping ring 26.

After the feeding is completed, the pressure on the cylinder body is removed to reset the disc spring set 23, at the moment, the clamping ring 26 is automatically pressed on the disc spring base 25 under the action of the disc spring set 23, and then the clamping driving mechanism drives the clamping ring mounting seat 1 to return to reset so as to be mounted next time.

By adopting the structure, the problem that the consistency of the disc spring hydraulic energy storage mechanism in the same batch is poor due to manual operation can be effectively avoided because the manual intervention is avoided in the assembly process of the clamping ring 26. Meanwhile, labor force is effectively liberated, and the assembly efficiency of the disc spring hydraulic energy storage mechanism is improved.

Based on the principle of the scheme, the embodiment 1 of the automatic clamp ring assembling device for the disc spring hydraulic energy storage mechanism is as follows:

an automatic assembling device for a clamp ring of a disc spring hydraulic energy storage mechanism can be structurally shown by referring to fig. 3-6, and is used for assembling the clamp ring 26 shown in fig. 2 to the disc spring hydraulic energy storage mechanism shown in fig. 1. The automatic assembling device for the disc spring hydraulic energy storage mechanism clamping ring comprises a base 21. The base 21 is provided with a positioning support seat 3 for positioning a disc spring base 25 for placing a disc spring hydraulic energy storage mechanism. After the positioning support seat 3 is positioned and placed on the disc spring base 25 of the disc spring hydraulic energy storage mechanism, certain pressure is applied to the cylinder body of the working cylinder 22 of the disc spring hydraulic energy storage mechanism, so that the cylinder body moves relative to the disc spring base 25, and meanwhile, the disc spring group 23 is compressed, so that the mounting groove of the clamping ring 26 on the disc spring hydraulic energy storage mechanism is exposed. The positioning support seat 3 is provided with a middle channel so that the positioning support seat 3 avoids the moving path of the open cylinder. The base 21 is also provided with a pair of snap ring mounting seats 1. The snap ring mounting seats 1 are provided with positioning and mounting structures for positioning and mounting the snap rings 26, and the paired snap ring mounting seats 1 are provided with clamping driving mechanisms for driving the snap ring mounting seats 1 to move oppositely and reversely. The lower side of the positioning support seat 3 is provided with an avoidance channel for the paired snap ring mounting seats 1 to radially pass through along the upper snap rings 26. When the cylinder body is pressed to the installation position, the clamping ring installation seat 1 is driven by the clamping driving mechanism to approach the disc spring hydraulic energy storage mechanism, and the clamping ring 26 on the clamping ring installation seat is sent into the clamping ring 26 installation groove on the disc spring hydraulic energy storage mechanism. After the completion of the feeding, the pressure on the cylinder is removed to restore the disc spring set 23. At this time, the snap ring 26 is automatically pressed against the disc spring base 25 under the action of the disc spring group 23. Then the clamping driving mechanism drives the snap ring mounting seat 1 to return to reset for the next mounting.

The key point of this embodiment is that the snap ring mounting seat 1 is provided with an arc-shaped positioning surface adapted to the outer ring surface of the snap ring 26. The arcuate locating surface mates with the outer annular surface of the snap ring 26, which means that the arcuate locating surface is concentric with the snap ring 26. While the snap ring 26 and cylinder would ideally require concentric assembly. Therefore, by adopting the structure, the precision of the assembly of the clamping ring 26 is conveniently ensured by aligning the arc-shaped positioning surface, the clamping ring 26 and the superposition of the circle centers of the cylinder body. The precision of location installation can be guaranteed only to the tight precision that just needs to guarantee snap ring 26 and arc locating surface subsides of operating personnel, and the simple operation also makes the dish spring hydraulic energy storage mechanism of same batch have good uniformity simultaneously. In addition, the arc-shaped positioning surface, the clamping ring 26 and the circle center of the cylinder body are in the coincident position during assembly, so that the three parts are convenient to use the same standard during design, processing and assembly, and therefore, the implementation is convenient. Of course, in some cases, for example, when the outer peripheral surface of the snap ring 26 is a conical surface or a prismatic surface surrounded by a plurality of surfaces, the positioning surface of the snap ring mounting seat 1 may be a conical surface or a prismatic surface adapted to the outer peripheral surface.

In addition, an electromagnet 2 can be arranged on the snap ring mounting seat 1. Current can be introduced to the electromagnet 2 before the snap ring 26 is installed in the mounting groove of the snap ring 26, so that the electromagnet 2 can adsorb the snap ring 26, the movement of the snap ring 26 relative to the mounting groove of the snap ring 26 is prevented, and further the influence on the assembly precision of the snap ring 26 is avoided. After the snap ring 26 is fitted into the snap ring 26 mounting groove, the current is stopped from flowing to the electromagnet 2, so that the snap ring 26 is separated from the electromagnet 2. Therefore, the magnetic force of the electromagnet 2 can be prevented from attracting the clamping ring 26 back again, and the influence of the magnetic force of the electromagnet 2 on the assembly accuracy of the clamping ring 26 is avoided. Of course, instead of the electromagnet 2, an electromagnetic buckle may be used. After the snap ring 26 is installed in the mounting groove of the snap ring 26, the electromagnetic buckle automatically buckles the snap ring 26 to prevent displacement. The snap ring mounting seat 1 drives the electromagnetic buckle and the snap ring 26 to move towards the disc spring hydraulic energy storage mechanism. After the snap ring 26 is installed into the snap ring 26 mounting groove, the electromagnetic buckle automatically releases to disengage the snap ring 26 from the restraint. This ensures that the retaining ability of the snap ring mounting base 1 to the position of the snap ring 26 is more reliable, but the structure is complex and the cost is high.

Based on the scheme principle and embodiment 1, embodiment 2 of the automatic assembling device for the clamp ring of the disc spring hydraulic energy storage mechanism is as follows:

compared with embodiment 1, the key point of the embodiment is that the automatic assembling device for the clamp ring of the disc spring hydraulic energy storage mechanism further comprises an identification module. The identification module is arranged on the chassis part corresponding to the mounting groove of the clamping ring 26 when the cylinder barrel is positioned at the mounting position of the clamping ring 26, so as to be used for identifying whether the clamping ring 26 is mounted in the mounting groove of the clamping ring 26. After the snap ring 26 is snapped into the snap ring 26 mounting groove, the identification module signals for further operation by the system or operator. Compared with the observation of human eyes, the identification module is adopted to identify whether the clamping ring 26 is installed in the mounting groove of the clamping ring 26, so that misjudgment can be avoided to the greatest extent, and further the consistency of the same batch of disc spring hydraulic energy storage mechanisms is guaranteed to be better. Meanwhile, the identification module is adopted for identification more conveniently, and the assembly efficiency is improved. In this embodiment, the recognition module preferably employs a high definition camera 7. The high-definition camera 7 is erected on a chassis part corresponding to the mounting groove of the clamping ring 26 when the cylinder barrel is positioned at the mounting position of the clamping ring 26, so as to be used for identifying whether the clamping ring 26 is mounted in the mounting groove of the clamping ring 26. When the high-definition camera 7 judges that the clamping ring 26 is clamped into the mounting groove of the clamping ring 26, a signal can be sent out so that the system or an operator can perform the next operation. In addition, an ultrasonic sensor may be used as the recognition module. The ultrasonic sensor is positioned more accurately, but is relatively expensive.

On the basis of the structure, the automatic assembling device for the disc spring hydraulic energy storage mechanism clamping ring can be additionally provided with a control module. The control module is in communication connection with the identification module and in control connection with the electromagnet 2, so that after the identification module identifies that the clamping ring 26 is in place, the electromagnet 2 is controlled to be powered off to stop adsorbing the clamping ring 26. In this way, errors caused by manual control of the electromagnet 2 in the assembly process of the clamping ring 26 can be further avoided, and the consistency of the disc spring hydraulic energy storage mechanisms in the same batch is further improved. Meanwhile, the process is high in automation degree, manual work is avoided to a great extent, and therefore efficiency is improved. Of course, the control module may be changed to control buttons. The recognition module recognizes that the snap ring 26 is in place and then sends out a prompt signal so that an operator can control the control button to conduct the on-off operation of the electromagnet 2. The control structure is low in cost and suitable for a scene of low-cost processing.

Furthermore, an in-place detection module for sending out an in-place signal when the cylinder body moves to the installation position of the clamping ring 26 can be additionally arranged on the automatic clamping ring assembling device of the disc spring hydraulic energy storage mechanism. The in-place detection module is in communication connection with the control module; the control module is in control connection with the clamping driving mechanism, and controls the movable seat of the clamping ring 26 to move in opposite directions after receiving the in-place signal sent by the in-place detection module so as to install the clamping ring 26. This allows for a fully automated assembly of the disc spring hydraulic energy storage mechanism snap ring assembly device with the snap ring 26. On this basis, the operator need only put in the snap ring 26 and press the cylinder. Meanwhile, the clamping ring 26 is fully automatic in assembly, so that the manual influence is completely avoided, the efficiency is high, and the consistency after assembly is good.

The in-place detection module is preferably a contact detection module. In this embodiment, the contact detection module specifically includes a ranging plate 6 disposed on the base 21 and facing the lower end of the cylinder. A compression spring 18 for resetting and a displacement sensor 19 for measuring the moving distance of the distance measuring plate 6 are laid between the distance measuring plate 6 and the base 21. The displacement sensors 19 are mounted on corresponding sensor mounting plates 17 on the base 21. The contact detection module can be triggered by contacting with the lower end of the cylinder body. When the cylinder body is pressed down to move, the lower end of the cylinder body is contacted with the ranging plate 6 and pushes the ranging plate 6 to move synchronously. At this time, the displacement sensor 19 reads the distance traveled by the ranging plate 6 and sends out an in-place signal when the cylinder reaches the mounting position of the snap ring 26. After the pressure on the cylinder body is removed and the disc spring set 23 is reset, the compression spring 18 can push the ranging plate 6 to reset due to the upward movement of the lower end of the cylinder body. The structure can accurately measure the movement of the cylinder body, has better stress and resetting capability, and is simple in structure and easy to realize and operate. Of course, proximity switches may also be employed for the in-place detection module herein. The proximity switch is arranged on the base 21 near the installation position of the clamping ring 26 so as to trigger the proximity switch when the lower end of the cylinder reaches the installation position of the clamping ring 26, and the proximity switch sends out an in-place signal. Besides, the in-place detection module can also adopt a normally open correlation photoelectric sensor. When the lower end of the cylinder reaches the mounting position of the clamping ring 26, the opposite-shooting photoelectric sensor is shielded, so that an in-place signal is sent out.

The parts not mentioned in this embodiment remain the same as in the other embodiments.

Based on the above scheme principle, embodiment 1 and embodiment 2, embodiment 3 of the automatic assembling device for the clamp ring of the disc spring hydraulic energy storage mechanism of the utility model is as follows:

in comparison with the embodiments 1 and 2, the key point of this embodiment is that the base 21 includes the fixing bases 9 disposed opposite to each other. The positioning support seat 3 is annular and is detachably connected to the upper surface of the fixed seat 9, so that the interval between the two opposite fixed seats 9 forms the avoidance channel. The structure is easy to form, has stronger bearing capacity and can be well pressed. On the basis, the positioning support seat 3 is detachable relative to the fixed seat 9, so that the automatic assembling device of the clamp ring of the disc spring hydraulic energy storage mechanism can specifically select and assemble the corresponding positioning support seat 3 according to the type of the disc spring hydraulic energy storage mechanism to be assembled. Correspondingly, the snap ring mounting seat 1 is detachably connected to the underframe. Thus, the corresponding snap ring mounting seat 1 can be specifically selected according to the type of the snap ring 26. Therefore, the automatic assembling device for the clamp ring of the disc spring hydraulic energy storage mechanism has wider application range, and is not limited by a single type of disc spring hydraulic energy storage mechanism, so that the applicability is better. Of course, when the automatic assembling device of the disc spring energy storage mechanism clamping ring 26 faces only a single disc spring energy storage mechanism, the positioning support seat 3 can be welded with the fixing seat 9 into a whole, so that the positioning support seat 3 and the fixing seat 9 have higher connection strength, and further bearing pressure can be better.

Based on the above structure, the paired snap ring mounts 1 can be preferably made to move synchronously in opposite directions and in opposite directions under the drive action of the snap driving mechanism. In this way, the feeding amount of the two-side snap ring mounting seat 1 can be kept the same at any time, and the snap ring 26 can be better mounted in a centering way with the snap ring 26 mounting groove. Thus, the trouble of aligning the snap ring 26 with the mounting groove of the snap ring 26 is avoided, and the assembly efficiency is effectively improved. Of course, the paired snap ring mounting bases 1 may each be provided with an independent snap-fit driving mechanism, such as an air cylinder or a hydraulic cylinder. When the assembling precision of the snap ring 26 and the snap ring 26 mounting groove is higher, the sheet body of the snap ring 26 on one side is firstly assembled into the snap ring 26 mounting groove, and then the sheet body of the snap ring 26 on the other side is assembled into the snap ring 26 mounting groove. Thus, the sheet body which is loaded later can be aligned with the sheet body which is loaded first, and the alignment is convenient. However, the above process is complicated and the corresponding structure is costly.

In order to facilitate the synchronous movement of the paired snap ring mounts 1 toward and away from each other, the snap-fit drive mechanism preferably employs a rack and pinion mechanism 13 and 12 as the force transmission path. The gear 13 of the gear 13 rack 12 mechanism is the power input end. And two racks 12 with the same modulus are oppositely arranged at two sides of the gear 13, so that the two racks 12 can be driven to move oppositely or reversely through the same gear 13. The paired snap ring mounting seats 1 are respectively fixed on two opposite racks 12. By adopting the structure, the transmission stability and reliability can be ensured while the synchronous opposite or opposite movement of the snap ring mounting seat 1 is ensured. Meanwhile, the structure is convenient for forming and maintenance, and has lower production and use costs.

In the present embodiment, the foregoing structure may be specifically arranged as follows.

Referring to fig. 3 to 6, the base 21 of the automatic assembling device for the disc spring hydraulic energy storage mechanism snap ring is specifically a rack structure, and the interior of the rack is hollow so as to accommodate the driving motor 4. The output end of the driving motor 4 is connected with a planetary reducer 5 so as to convert the output rotating speed of the driving motor 4 into a required rotating speed. The output end of the planetary reducer 5 is connected with a right-angle commutator 8, and the output end of the right-angle commutator 8 is connected with a horizontally placed gear 13. Under the commutation action of the right-angle commutator 8, the torque output by the drive motor 4 is converted into a torque that turns the horizontally arranged gear 13. Due to the fact that the axial dimensions of the driving motor 4 and the planetary reducer 5 are large, the large transverse space inside the rack structure can be used for accommodating the motor and the planetary reducer 5 by adopting the structure, and therefore the layout of all parts on the base 21 is more compact. Two racks 12 with the same modulus are respectively arranged on two sides of the gear 13 so as to synchronously move towards or away from each other under the action of the gear 13. The rack 12 is provided with a deep groove ball bearing 14 at the side and a plane linear bearing 11 at the lower side to make the rack 12 have a definite and stable linear motion track and reduce the friction resistance when the rack 12 moves linearly. The portion of the chassis located on the outward side of the two racks 12 is laid with a backing plate 20 so as to stably carry the snap ring mount 1. The backing plate 20 may preferably be made of a copper-based material to reduce friction with respect to the backing plate 20 when the snap ring mount 1 is moved. The base plate 20 is also provided with a fixing seat 9 so that the positioning support seat 3 is detachably connected to the upper end surface thereof through a quick locking pin 10. The snap ring mount 1 is detachably mounted on the rack 12 by means of guide pins 16 so as to move in synchronization with the rack 12. The backing plate 20 is correspondingly provided with an avoidance groove for avoiding the guide pin 16. A linear bearing 15 is arranged between the avoidance groove and the guide pin 16 so as to reduce friction between the two.

Of course, it is readily conceivable that the aforementioned gear 13 and rack 12 structure could be replaced by a lead screw nut structure. Specifically, the screw thread with opposite rotation directions is arranged at the two ends of the screw rod nut structure. The middle part of the screw is provided with a gear 13 coaxial with the screw. The tail end of the planetary reducer 5 is also externally connected with a transmission gear 13 so as to drive the screw rod to rotate through a gear 13 pair. A transmission nut is arranged below the snap ring mounting seat 1 and is respectively connected with two ends of the screw rod in a threaded manner through the transmission nut. When the screw rod rotates under the action of the driving motor 4, the snap ring mounting seats 1 at two sides synchronously move in opposite directions or in opposite directions through the screw rod nut structure.

Alternatively, the rack gear 12 of the gear 13 may be replaced by a link structure. Specifically, the output end of the planetary reducer 5 is fixedly connected to the center of the driving rod. The two ends of the driving rod are respectively provided with a sliding groove. In addition, two driven slide bars and a guide rail for the linear movement of the driven slide bars are respectively arranged on two sides of the driving rod. The driven slide bar is hinged in a sliding groove on the driving bar, so that the hinge shaft of the driven slide bar and the driving bar can slide in the sliding groove along the extending direction of the driving bar. The snap ring mounting seats 1 are respectively and fixedly mounted on the driven slide bars so as to synchronously and linearly move with the driven slide bars.
