Technical Field
[0001] This utility model relates to the field of product assembly technology, specifically to an assembly fixture for products. Background Technology
[0002] Product assembly fixtures are specialized tooling equipment used to fix, position, protect and support workpieces or tools. Their core function is to improve assembly efficiency and quality. They are widely used in fields such as mechanical manufacturing, electronic assembly, and welding processing, and are especially suitable for processes that require high repeatability or complex processes.
[0003] Currently, the main process involves manually attaching the spring to the shaft of the pre-assembled product, then placing the pre-assembled product and the spring on the assembly table, and finally placing two sets of snap fasteners on the clamps of the assembly table. The snap fasteners are then pushed by a cylinder to engage with the end of the shaft, allowing for assembly.
[0004] However, currently, the assembly is mainly done manually by fitting the springs onto the product's shaft. Some springs and products are quite small in size, making it easy for the operator's hand to vibrate when assembling smaller springs. This makes it difficult to accurately and quickly fit the springs onto the shaft, reducing the overall efficiency of product assembly. Utility Model Content

A bidirectional screw is provided at the bottom of the limiting member.
[0008] A limiting component is disposed between an assembly device and a product part. The limiting component is used to limit the product part. The limiting component includes a limiting rod that is slidably connected to the side wall of the assembly device. A lead screw is provided on the side wall of the limiting rod.
[0009] Preferably, the assembly component further includes a concave part, which is fixedly connected to the bottom of the limiting member, and the top of the assembly equipment is provided with a sliding groove, in which the concave part is slidably connected.
[0010] Preferably, the bidirectional screw is rotatably connected inside the slide groove, and the concave part is threadedly connected to the outer wall of the bidirectional screw.
[0011] Preferably, a motor is fixedly installed inside the slide groove, and the output shaft of the motor is fixedly connected to a bidirectional screw.
[0012] Preferably, a stabilizing rod is fixedly connected to the side wall of the assembly equipment, and a stabilizing groove is formed on the side wall of the limiting member, with the stabilizing rod slidably connected to the inner wall of the stabilizing groove.
[0013] Preferably, the limiting component further includes a connecting plate, which is fixedly connected to the end of the limiting rod, rotatably connected to the outer wall of the lead screw, and the lead screw is threadedly connected to the side wall of the assembly equipment.
[0014] Preferably, a limiting plate is fixedly connected to the end of the limiting rod, and a limiting hole is opened in the side wall of the assembly equipment, with the limiting plate snapping into the inner wall of the limiting hole.
[0015] Preferably, a rubber pad is fixedly connected to the side wall of the limiting plate, and the rubber pad abuts against the side wall of the product part.
[0016] Compared with the prior art, the beneficial effects of this utility model are: by setting an assembly assembly between the assembly equipment and the assembly spring, and by placing the assembly spring between the limiting parts on the assembly assembly, the product parts can be quickly inserted into the assembly spring for assembly, thereby improving the assembly efficiency of the product parts and the assembly spring.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0026] like Figure 1 - Figure 5 As shown, this application provides an assembly fixture for a product, including an assembly device 1 and a product part 2 and an assembly spring 201 disposed on the assembly device 1; it also includes;
[0027] Specifically, such as Figure 2 As shown, an assembly assembly 3 is provided between the assembly equipment 1 and the assembly spring 201. The assembly assembly 3 is used to limit the assembly spring 201. The assembly assembly 3 includes a limiting member 301, which is slidably connected to the top of the assembly equipment 1. The assembly spring 201 is placed between two sets of limiting members 301. A bidirectional screw 303 is provided at the bottom of the limiting member 301. By providing the assembly assembly 3 between the assembly equipment 1 and the assembly spring 201, the two sets of limiting members 301 can be moved by rotating the bidirectional screw 303 on the assembly assembly 3. At this time, the assembly spring 201 can be placed on the two sets of limiting members 301, and the product part 2 can be quickly inserted into the assembly spring 201 for assembly, thereby improving the assembly efficiency of the product part 2 and the assembly spring 201.
[0028] Specifically, such as Figure 3As shown, a concave part 302 is fixedly connected to the bottom of the limiting part 301, and a slide groove 3021 is provided on the top of the assembly equipment 1. The concave part 302 is slidably connected inside the slide groove 3021, and the bidirectional screw 303 is rotatably connected inside the slide groove 3021. The concave part 302 is threadedly connected to the outer wall of the bidirectional screw 303. A motor is fixedly installed inside the slide groove 3021, and the output shaft of the motor is fixedly connected to the bidirectional screw 303. The motor can drive the bidirectional screw 303 to rotate, and at the same time, the bidirectional screw 303 can drive the two sets of limiting parts 301 to move towards each other, which is convenient for adjustment according to the assembly spring 201 of different sizes, and further improves its applicability.
[0029] Specifically, such as Figure 4 As shown, a stabilizing rod 304 is fixedly connected to the side wall of the assembly equipment 1, and a stabilizing groove 3041 is provided on the side wall of the limiting member 301. The stabilizing rod 304 is slidably connected to the inner wall of the stabilizing groove 3041, and the stability of the limiting member 301 during sliding adjustment is improved by the stabilizing rod 304.
[0030] Specifically, such as Figure 3 As shown, a limiting component 4 is provided between the assembly equipment 1 and the product part 2. The limiting component 4 is used to limit the product part 2. The limiting component 4 includes a limiting rod 401, which is slidably connected to the side wall of the assembly equipment 1. A lead screw 403 is provided on the side wall of the limiting rod 401. By providing the limiting component 4 between the assembly equipment 1 and the product part 2, and by rotating the lead screw 403 on the limiting component 4, it is easy to drive the limiting rod 401 to limit the product part 2. This facilitates the subsequent assembly of the snap fastener by pressing it onto the product part 2, thereby improving the stability and convenience of the assembly.
[0031] A connecting plate 402 is fixedly connected to the end of the limiting rod 401. The connecting plate 402 is rotatably connected to the outer wall of the lead screw 403. The lead screw 403 is threadedly connected to the side wall of the assembly equipment 1. By rotating the lead screw 403 inward, the limiting rod 401 can drive the product part 2 to be inserted into the bidirectional screw 303 and limited.
[0032] Specifically, such as Figure 5 As shown, a limiting plate 404 is fixedly connected to the end of the limiting rod 401. A limiting hole 4041 is opened on the side wall of the assembly equipment 1. The limiting plate 404 is snapped into the inner wall of the limiting hole 4041. A rubber pad 405 is fixedly connected to the side wall of the limiting plate 404. The rubber pad 405 abuts against the side wall of the product part 2.
[0033] The specific steps of this solution are as follows: First, based on the dimensions of the assembly spring 201, the bidirectional screw 303 is rotated by a motor. Simultaneously, the bidirectional screw 303 can drive the two sets of limiting parts 301 to move to both sides until the distance between the two sets of limiting parts 301 is appropriate to the bidirectional screw 303. Next, the bidirectional screw 303 is placed between the limiting parts 301, and the snap fastener is placed at the moving clamp on the assembly equipment 1. Finally, the product part 2 is placed on top of the assembly equipment 1, and by rotating the lead screw 403 inward, the product part 2 can be inserted into the bidirectional screw 303 through the limiting rod 401. Then, the snap fastener at the moving clamp is pushed by a cylinder and locked onto the product part 2 for assembly.
