[0015] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0016] Embodiment one

[0017] Figure 3 The torsion spring shaft assembling device shown in the background art can be used for Figure 1 The torsion spring shaft assembling of the product shown in the background art, the device comprises a jig 10, a pressing unit 20 and a pushing unit 30, the pressing unit is located above the jig, and the pushing unit is located on the side of the jig.

[0018] The jig 10 comprises a bottom plate 11 and a carrier plate 12, the carrier plate is arranged on the bottom plate, the carrier plate 12 is provided with a positioning cavity 13, and the two sides of the carrier plate are provided with first V-shaped grooves 14 in communication with the positioning cavity. The product with the assembled torsion spring is placed in the positioning cavity, and the torsion spring shaft is placed in the first V-shaped groove 14.

[0019] The pressing unit 20 comprises a first air cylinder 21, a pressing block 22, a cover plate 23 and a base plate 24, the pressing block and the cover plate are fixed to the bottom of the base plate, and the telescopic rod of the first air cylinder 21 is fixedly connected with the base plate. The first air cylinder drives the pressing block to move downward to press the torsion spring and the product, the bottom of the cover plate is provided with a second V-shaped groove 25, the first air cylinder drives the cover plate to move downward to be buckled on the carrier plate, and the first V-shaped groove and the second V-shaped groove form a square accommodating groove.

[0020] The pushing unit 30 includes two groups of pushing mechanisms arranged on the two sides of the jig. The pushing mechanism includes a second cylinder 31 and a pushing block 32. The pushing block is provided with a pushing rod 33 capable of penetrating the accommodating groove on one side of the jig 10. The second cylinder drives the pushing block to move towards the jig. The pushing rod 33 is inserted into the accommodating groove to push the torsion spring shaft to move along the hole of the product. When the torsion spring shaft is separated from the accommodating groove, the torsion spring shaft is inserted into the hole and the torsion spring. According to actual application needs, the second cylinder can continue to push the torsion spring shaft to advance a distance, so that the torsion spring shaft is assembled more firmly.

[0021] After the assembly of the torsion spring shaft is completed, the second cylinder is driven to withdraw from the accommodating groove. The first cylinder 21 drives the pressing block 22 and the cover plate 23 to move upwards. The worker or the transfer device takes out the product from the positioning groove.

[0022] In some embodiments, a cavity 321 is arranged in the pushing block 32. The head of the pushing rod is located in the cavity. A third spring 34 connected with the pushing rod 33 is arranged in the cavity. When the pushing rod touches the torsion spring shaft, if the friction between the torsion spring shaft and the V-shaped groove is too large, the pushing rod moves backward to compress the third spring 34. When the pushing rod 33 touches the sensor arranged in the cavity, the second cylinder stops moving. In this way, the pushing rod or the torsion spring shaft can be prevented from being damaged.

[0023] In some embodiments, in order to facilitate the taking out of the product, a slot hole is arranged in the positioning cavity 13 of the carrier plate 12. A floating plate 40 is placed in the slot hole. When the product is fed, the top surface of the floating plate is flush with the bottom surface of the positioning cavity. When the product is discharged, a third cylinder 50 arranged below the bottom plate drives the floating plate 40 to rise to push the product out of the positioning cavity, thereby facilitating the discharge.

[0024] In some embodiments, in order to prevent the torsion spring shaft from being stuck during movement in the accommodating cavity or the surface of the torsion spring shaft from being seriously scratched, the square accommodating groove is designed as a deformable structure. The size of the accommodating groove can be adjusted according to the actual state. Specifically, a recess is arranged on the carrier plate. A carrier block 60 is placed in the recess. The bottom of the carrier block is provided with a first spring 70 connected with the carrier plate. The first V-shaped groove 14 is arranged on the top of the carrier block 60. When the first spring 70 is compressed, the carrier block slightly moves downward. At this time, the size of the accommodating groove changes adaptively. And / or, the bottom of the cover plate 23 is provided with a movable block 80. The movable block and the cover plate are connected through a second spring 90. The second V-shaped groove 25 is arranged on the bottom of the movable block 80. When the second spring 90 is compressed, the movable block slightly moves upward. At this time, the size of the accommodating groove also changes adaptively.

[0026] This embodiment is based on Example One.

[0027] The carrier plate 12 is provided with two positioning cavities 13, and a translation driving assembly is arranged below the jig, which drives the jig to translate so that the two positioning cavities 13 are respectively moved to below the material pressing unit 20. Specifically, the translation driving assembly comprises a guide rail 100 and a fourth cylinder 110, the jig is slidingly connected to the guide rail, and the fourth cylinder drives the jig to translate along the guide rail.

[0028] While the product below the material pressing unit is assembled with the torsion spring shaft, another positioning cavity can be fed or unloaded, so that the assembly efficiency is further improved.

[0029] The above description of disclosed embodiments enables those skilled in the art to carry out or use the present application. Various modifications to the above-described embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the application.
