The spring assembly assembling jig can adjust the relative positions of the first sliding unit 220 and the first fixing unit 210 according to a predetermined track by arranging the first sliding unit 220 moving along the first direction X; by means of the arrangement that the connecting block 312 on the second positioning assembly 300 passes through the avoidance hole 321 and the second elastic piece 330 elastically connects the connecting block 312 and the avoidance hole 321, the risk of position deviation of the second sliding unit 320 is reduced, smooth operation of the second sliding unit 320 is ensured, and the relative positions of the second sliding unit 320 and the second fixing unit 310 are adjusted according to a preset track. The spring assembly assembling jig plans the movable ranges of the first and second sliding units 220 and 320 by improving the structures of the first and second positioning assemblies 200 and 300, reduces the risk of positional deviation, and simultaneously ensures the movable capability. The accuracy of assembling the spring assembly product 900 is improved, the assembly yield and efficiency are guaranteed, the situation that the assembly error of the spring assembly product 900 is overlarge is avoided, and the risks of unsmooth matching and blocking are reduced.

The spring assembly assembling jig is assembled by multiple modules, has the advantages of simple assembly, easy replacement and the like, and has the advantages of no abnormal matters such as jamming, abrasion, rust and the like in long-term use, reliable quality and strong stability. The spring assembly assembling jig has the same design pattern of the main body when assembling the spring assembly products 900 in different motors, but requires the first and second positioning assemblies 200 and 300 to be matched with each other with respect to the outer shape of the spring assembly products 900.

In this embodiment, the second elastic member 330 is disposed in the avoidance hole 321, and the length direction of the second elastic member 330 is located in the second direction Y. The above design effectively simplifies the structure of the second positioning assembly 300, reduces the risk of positional deviation and damage of the second elastic member 330, reduces occupied space, improves the compactness of the structure, and ensures that the second sliding unit 320 can accurately complete the relative movement with the second fixing unit 310 according to a predetermined trajectory. Specifically, the second elastic member 330 is a telescopic spring; the avoidance hole 321 is a long hole, the length direction of the long hole is in the second direction Y, and two side surfaces of the connecting block 312 are always attached to the hole wall of the avoidance hole 321. The above design further defines the movement track of the second sliding unit 320, effectively reducing the risk of the second sliding unit 320 being shifted in position.

Because the spring assembly product 900 is an elastic workpiece, if the two ends are fixed by the positioning inserts 224, after the assembly of the spring assembly product 900 is completed, when the spring assembly product 900 is taken out from the spring assembly jig, one end of the spring assembly product 900 is dead, and distortion is generated, so that the assembly yield is greatly affected. The positioning insert 224 of the spring assembly product 900 therefore needs to be constructed with one end fixed and the other end movable. In the present embodiment, the first fixing unit 210 serves as a fixed positioning insert 224, and the first sliding unit 220 serves as a movable positioning insert 224.

Illustratively, the spring assembly 900 has a first positioning slot 910 and a second positioning slot 920, the first fixing unit 210 has a first fixing end 211 capable of being inserted into the first positioning slot 910, and the first sliding unit 220 has a second fixing end 222 capable of being inserted into the second positioning slot 920. With the above design, the positioning effect of the first positioning assembly 200 on the spring assembly product 900 is achieved, positioning of the spring assembly product 900 in the first direction X is facilitated, and an operator changes the position of the second positioning groove 920 on the spring assembly product 900 by driving the first sliding unit 220, so that product positioning operation is completed.

Specifically, the first sliding unit 220 is movable in the first direction X by 0.1 mm.

Further, the first sliding unit 220 includes a pushing reference block 223 and a positioning insert 224 fixedly connected to the pushing reference block 223, the pushing reference block 223 moves relative to the jig main body 800 along the first direction X, the pushing reference block 223 is fixedly connected with a connecting end 221, the first elastic member 230 elastically connects the connecting end 221 and the jig main body 800, the length direction of the first elastic member 230 is located in the first direction X, and the second fixed end 222 is disposed on the positioning insert 224. The arrangement of the pushing reference block 223 effectively improves the assembly precision of the spring assembly product 900, and ensures the smooth completion of the assembly operation of the spring assembly product 900. The design of the elastic connection end 221 of the first elastic member 230 and the jig main body 800 realizes the elastic connection between the first sliding unit 220 and the jig main body 800, ensures that the first sliding unit 220 can slide smoothly relative to the first fixing unit 210, and ensures the smooth operation of the first positioning assembly 200.

Specifically, the first elastic member 230 is a telescopic spring. The first elastic member 230 can store elastic potential energy when the push reference block 223 is pushed by an external force, and after the external pushing force disappears, the elastic potential energy of the first elastic member 230 is released and returns to an initial state. The above design realizes the reset action of the first sliding unit 220.

In other implementations of this embodiment, the push reference block 223 also has a free-moving auxiliary push reference structure mounted thereon.

In this embodiment, the first positioning assembly 200 includes a guide pin 240 fixedly connected to the jig main body 800, the guide pin 240 extends along the first direction X, and the first sliding unit 220 is sleeved on the guide pin 240. The arrangement of the guide pin 240 serves as a guide for the first slider unit 220, further reducing the risk of positional deviation caused by movement of the first slider unit 220.

Illustratively, the second fixing unit 310 has a clamping surface on a side surface, the second sliding unit 320 is fixedly connected with the side pushing insert 322, and the spring assembly product 900 can be clamped between the side pushing insert 322 and the clamping surface. The above design makes the second sliding unit 320 through the mode of moving relative to the second fixing unit 310, can reach the purpose of carrying out the centre gripping to the spring assembly product 900, and above design has ensured the centre gripping effect of second locating component 300 to the spring assembly product 900, has reduced the risk that spring assembly product 900 breaks away from the equipment position because of the accident, has ensured the smooth operation of spring assembly equipment tool.

Under the action of external pushing force, the side pushing insert 322 moves away from the clamping surface along the second direction Y and generates a gap, so that the spring assembly product 900 can be placed between the clamping surface and the side pushing insert 322, and after the external pushing force disappears, the side pushing insert 322 moves towards the clamping surface and completes the clamping action on the spring assembly product 900. Specifically, the second elastic member 330 is a telescopic spring. The second elastic member 330 can store elastic potential energy when the second sliding unit 320 is pushed by an external force, and after the external pushing force is removed, the elastic potential energy of the second elastic member 330 is released and returns to an original state. The above design realizes the reset action of the second slider unit 320.

Further, the spring assembly product 900 surrounds the assembly product slot 901 and the side pushes the insert 322 through the assembly product slot 901. The above design improves the clamping mode of the second positioning assembly 300 on the spring assembly product 900, reduces the risk of position deviation of the spring assembly product 900, and ensures the assembly yield and efficiency of the spring assembly product 900.

Still further, the side push insert 322 is connected to the second sliding unit 320 through a reinforcing block 323. The provision of the reinforcing block 323 enhances the supporting ability of the second sliding unit 320 to the side pushing insert 322, reduces the risk of damage deformation, improves the strength of the structure, and prolongs the service life of the second sliding unit 320. Specifically, the side push insert 322 is shaped as a double sided support.

Illustratively, the second stationary unit 310 is provided with a suction member 311 for sucking the spring assembly product 900. Specifically, the adsorbing member 311 is provided on the holding surface. The suction member 311 includes two cylindrical permanent magnets; the surface of the side push insert 322 is mounted with a permanent magnet for attracting the spring assembly product 900. The adsorption piece 311 is used for adsorbing the outer connecting block and the spring main body on the spring assembly product 900, and can reserve an operation gap for the assembly action of the subsequent outer limiting block.

Further, one end of the adsorbing member 311 is exposed to the clamping surface. The design is helpful for determining the relative position of the absorption part 311 and the spring assembly product 900, ensures the accurate positioning of the spring assembly product 900 on the spring assembly jig, and improves the efficiency of assembly operation.

In this embodiment, the first direction X and the second direction Y are both located in a horizontal plane, and the first direction X is perpendicular to the second direction Y. The determination of the first direction X and the second direction Y defines the direction in which the first positioning assembly 200 and the second positioning assembly 300 perform position adjustment on the adsorption spring assembly product 900, optimizes the layout of the spring assembly jig, reduces occupied space, and improves the compactness of the structure. The amount of operator effort is reduced and the risk of misalignment of the spring assembly product 900 is reduced.

In the assembling operation of the spring assembly assembling jig provided in this embodiment, the second sliding unit 320 needs to be pushed first to make the side pushing insert 322 far away from the clamping surface, and then the outer connecting block on the spring assembly product 900 is placed between the side pushing insert 322 and the clamping surface; then stopping pushing the second sliding unit 320 to enable the outer connecting block to be tightly attached to the clamping surface; then, the side pushing insert 322 is controlled to be away from the clamping surface again, and the spring main body and the outer limiting block on the spring assembly product 900 are assembled; then stopping pushing the second sliding unit 320 again, so that the outer connecting block, the spring main body and the outer limiting block are tightly attached to the clamping surface; assembling an outer limiting block on the spring assembly product 900, so that a first positioning groove 910 on the outer limiting block is clamped on the first fixed end 211, and a second positioning groove 920 on the outer connecting block is clamped on the second fixed end 222; the spring assembly product 900 is urged to a reference in the first direction X to complete product positioning.
