In this embodiment, in order to solve the technical problems that the replacement operation is complicated and the efficiency is low when the roller is ground and processing, continuous automatic production is difficult to realize, through continuous improvement, the device for vertically clamping the roller and grinding is specially designed, automatic clamping can be well realized, automatic clamping can be realized in a form of a production line, after grinding is finished, another roller to be ground can be automatically unloaded and loaded, automatic grinding of the roller is well realized, and the whole occupation area of the device can be well controlled by adopting a mode of vertically clamping the roller.
The vertical clamping is realized through the clamping machine 1 of special design, consider the roll clamping back, on the one hand need keep vertical rotation, on the other hand need guarantee stability, on the other hand need can realize high-efficient automatic clamping, these problems are synthesized together and are not considered so on the one hand by the skilled person in the art, on the other hand is not known how to realize yet, the mode of this scheme selection is, drive ring gear 103 is set up around rotating pedestal 101, realize the rotation by rotating drive arrangement drive, and be provided with wedge locking piece 106 in the cylindricality space 102 on the rotating pedestal 101, wedge locking piece 106 has enclosed into the round, can be used for carrying out fine locking and the unblock when required to roll neck a01 of roll a in between, thereby with wedge locking piece 106 fine locking clamping, in order to grind.
The roll neck a01 is locked when the inner diameter of the wedge-shaped locking piece 106 of one circle is reduced, unlocking is realized when the inner diameter is increased, the change is realized through the movement of the annular pressing piece 104, the inner wall of the annular pressing piece 104 is provided with a conical inner wall 105 with the gradually reduced diameter from top to bottom, namely an inverted conical surface, when the annular pressing piece 104 moves upwards, the wedge-shaped locking piece 106 of one circle is well compressed, the inner diameter is gradually reduced, thereby the roll neck a01 is well locked, the roll a is usually large in diameter and large in weight, a large gravity effect can be provided when the roll neck a is improved to be vertically clamped, the roll neck a01 is more compressed and more tightly under the action of the friction force of the roll neck a01 and the wedge-shaped locking piece of one circle, the clamping effect is ensured, and the vertical height of the wedge-shaped locking piece 106 can be designed to be higher by one length in the vertical direction according to the requirement, so that the roll neck a01 can have a good perpendicularity, and the unstable supporting and tiny inclination caused by clamping of only one end of the roll neck a01 is avoided; the downward movement of the ring press 104 increases the inner diameter of the wedge lock 106 to unlock the roll neck a01 when it is needed to be replaced after it is clamped. The inner wall of the wedge lock 106 may be roughened or embedded with a material having a high coefficient of friction, thereby increasing the friction with the roll neck a01 and thus improving the locking effect.
The lifting or the trend of the lifting of the annular pressing piece 104 is realized through the first elastic piece 109, so that the force for pressing the annular pressing piece 104 to the outer wall of the wedge-shaped locking piece 106 is provided, the self-locking after clamping is ensured, the greater the locking force required by the heavier roller a is, and the self-locking structure is adopted, so that the locking force can be automatically improved, and the stability of the structure is well realized; the descent of the ring presser 104 is achieved by increasing the pressure in the ring cavity 110, the ring presser 104 and the inner wall of the cylindrical space 102 forming a sealed ring cavity 110, the ring cavity 110 acting on a acted-on portion of the ring presser 104, such as an acting surface, after increasing the pressure, causing it to move downwards away from the wedge lock 106, thus achieving unlocking. The realization of stable locking and quick unlocking is well provided as a whole.
In this embodiment, the wedge lock 106 is a plurality of rings, and needs to be well supported in a sliding manner to play a role, and during the supporting, the retainer 107 rotates along with the rotating base 101, the wedge lock 106 guides through the slot 108 in the retainer 107, so that vertical guiding and radial moving guiding can be realized, and the corresponding limiting part can be designed to limit the wedge lock 106 not to move up and down and move radially too much, and only the wedge lock is allowed to move in a required range, thereby ensuring locking and unlocking effects. Therefore, the roller a is well clamped and dismounted, the clamped grinding is performed through the grinding mechanism 2, and after the roller a is clamped and locked, the clamping mechanism 1 is driven to drive the roller a to vertically rotate, and the grinding mechanism 2 moves to be in contact with the roller a, so that the roller a can be ground.
In the embodiment, because the roller a is vertically arranged and is clamped through a single end, compared with the bidirectional clamping in the prior art, the centering which is needed when the two ends are clamped is not needed to be considered, so that the clamping process is greatly simplified, the concentricity of rotation after vertical clamping is well ensured, and the grinding efficiency and the product quality of the roller are fundamentally ensured.
Further, the clamping mechanism 1 further comprises,
two clamping blocks 111 are arranged on the rotary seat body 101 in a relative movement manner along the radial direction of the roll neck a01, are positioned below the annular pressing piece 104 and are positioned at two sides of the joint a02,
a second elastic member 112 for providing a force of the clamping blocks 111 toward each other,
wherein, the end of the two clamping blocks 111 away from each other is acted on by the pressure in the annular cavity 110, when the pressure in the annular cavity 110 increases, the pressure acts on the two clamping blocks 111 to realize the separation of the two.
In the embodiment, considering that the roller a is vertically arranged, in order to realize quick automatic clamping and clamping cancellation, the single-end clamping is adopted in the scheme, the clamping for the roller neck a01 is specially designed to further ensure the stability and the perpendicularity of the clamping, the roller neck a01 and the joint a02 are locked from two different positions in the vertical direction, and the roller neck a01 and the joint a02 are staggered, so that the staggered locking can be realized, and the locking modes are different, so that the double clamping and locking effects are achieved.
The locking at the position of the joint a02 is realized through two clamping blocks 111, the roll neck a01 is usually used for bearing a bearing and is cylindrical, the invention designs that the wedge-shaped locking block 106 and the roll neck a01 are driven by friction force between the wedge-shaped locking block 106 and the roll neck a01 to realize the rotation of the roll a, and though a self-locking mechanism exists, the situation that the wedge-shaped locking block 106 and the roll neck a01 generate tiny relative rotation still exists is still certain, therefore, the inventor perfects further, considering that the joint a02 is usually used for transmitting power, two clamping blocks 111 are specially designed at two sides of the joint a02 to realize the clamping of the joint a02 because clamping surfaces exist, the fact that the joint a02 can not generate relative rotation relative to the clamping blocks 111 is basically determined, and the fact that the roll a can not generate relative rotation relative to the wedge-shaped locking block 106 and the rotating seat 101 is also determined, so that the rotation of the rotating seat 101 in the grinding process is very stable, and the grinding effect is ensured.
The clamping block 111 keeps the clamping force of the joint a02 to be realized by the fact that the second elastic piece 112 supports the clamping block 111 firmly, although the clamping block cannot be self-locked, the clamping block is mutually matched with the wedge-shaped locking block 106 for locking the roll neck a01, so that self-locking can be guaranteed as a whole, relative rotation can not be generated, the clamping of the joint a02 by the clamping block 111 is well realized, the combined effect of the wedge-shaped locking block 106 for locking the roll neck a01 is well realized, double assurance is realized, the stability of the roll a is improved, vertical clamping is realized, perpendicularity is guaranteed, and the stability in rotation can be kept, so that the automatic pipeline grinding of the roll a is realized stably and efficiently.
When the two clamping blocks 111 need to cancel clamping the joint a02 to discharge the roll a, the clamping is realized by pressurizing the annular cavity 110, and after the annular cavity 110 is pressurized, pressure acts on one ends of the two clamping blocks 111 to realize that the two clamping blocks are far away from each other, so that the clamping of the roll a is canceled to discharge the roll a, and the synchronous unlocking and clamping canceling of the wedge-shaped locking blocks 106 and the clamping blocks 111 are well realized. The pressurizing process can be realized by hydraulic pressure or pneumatic pressure, and proper unlocking pressure can be selected according to different situations.
Further, also include
A one-way valve 113 provided on the rotary body 101, one end connecting port communicating with the annular chamber 110, the other end connecting port facing outward in the radial direction of the rotary body 101,
the quick connector 114 is communicated with a pressure source, is movably arranged on one side of the rotary seat body 101, and is provided with a coating cavity 115 at one end close to the rotary seat body 101, and the quick connector 114 is moved to be close to one side of the rotary seat body 101, so that the coating cavity 115 is communicated with the check valve 113 in a sealing manner.
In this embodiment, considering that the rotating base 101 needs to rotate, so as to ensure that the rotation grinding of the roller a is achieved, but meanwhile, the annular cavity 110 needs to be unlocked by air pressure or hydraulic pressure, when the grinding is just unlocked, the rotating base 101 is completed and is stationary, therefore, the quick connector 114 is specially designed to realize quick communication with the annular cavity 110, on the one hand, the quick connector 114 does not need to rotate synchronously with the rotating base 101, so that the structure is simpler, on the other hand, the quick connector 114 only needs to be connected briefly, pressure transmission can be achieved, and very high connection stability is not needed, and the quick connector 114 is specially designed to be in a quick connection mode, the coating cavity 115 on the quick connector 114 is arranged in a moving mode, can be tightly attached to the outer wall of the rotating base 101, so that sealing connection with the annular cavity 110 is achieved, thereby carrying out required pressure transmission, not only is convenient, but also meets the quick connection requirement, and achieves a very good effect. Considering that under the condition of selecting hydraulic pressure such as water as a medium to carry out transmission pressure, when the quick connector 114 leaves the joint surface of the rotary base body 101, the water is prevented from being directly sprayed out, the one-way valve 113 is specially designed, the quick connector 114 can feed water into the annular cavity 110 unidirectionally through the one-way valve 113, but the annular cavity 110 cannot discharge water towards the quick connector 114, so that the occurrence of water spraying can be avoided, and the pressure in the annular cavity 110 can be kept for a certain time, thereby facilitating the installation of a roller a to be ground next, and on the other hand, the annular cavity 110 can be designed to have an automatic pressure relief opening to realize pressure relief, or the tightness of the annular cavity 110 is not very high, and the automatic pressure relief can be completed in a short time, thereby meeting the requirements of various scenes.
Further, the wedge lock 106 has a radial limit portion 116, the retainer 107 has a radial limit groove 117, and the radial limit portion 116 is disposed in the radial limit groove 117 and can realize radial movement and lifting movement within a limit range.
In this embodiment, the wedge lock 106 has a radial limiting portion 116, so that the wedge lock 106 does not excessively move to the center or move around in the radial direction, and thus the wedge lock is dropped from the retainer 107, which is required to achieve that the wedge lock 106 is mounted on the retainer 107 and can maintain good mobility.
Further, the ring presser 104 has a guide groove portion 118, and the guide groove portion 118 is provided in the rotary base 101 in a vertically sliding manner, and one end of the first elastic member 109 acts on the rotary base 101 and one end acts on the ring presser 104.
In this embodiment, many details can be well within the ability of those skilled in the art, for example, in order to ensure the sliding stability of the ring-shaped pressing member 104, the larger the contact area between the guiding portion of the guiding groove portion 118 and the rotating base 101 is, the more stable the sliding is, and the first elastic member 109 may also be a spring, where one end acts on the rotating base 101 and the other end acts on the ring-shaped pressing member 104, so as to achieve the required locking elastic force.
