An elastic clamping fixture for the production of mobile phone cases, comprising a base, the base is equipped with a cylinder and a support column, one end of the support column is fixed to the base, and the other end is connected to a base plate, and the base plate is provided with a through hole. The pull rod of the air cylinder passes through the through hole and is connected with the elastic lock mouth unit for clamping the processed product. The elastic lock mouth unit includes a chuck and an expansion piece. In the hole, the expansion member is fixedly connected with the end of the tie rod facing away from the cylinder. The chuck includes a mounting part and a clamping part.

A further improvement of the technical solution is that the connection between the mounting part and the clamping part is provided with rounded corners.

A further improvement of the technical solution is that the number of the elastic lock mouth unit is at least one.

A further improvement of the technical solution is that the longitudinal section of the expansion member is an isosceles trapezoid, and the expansion hole is a tapered hole.

A further improvement of the technical solution is that the number of the support columns is four, which are respectively arranged at the four corners of the base.

A further improvement of the technical solution is that the height of the protrusion of the boss is 1-3 mm.

The beneficial effects of the utility model are:

The utility model has a simple structure, adopts the elastic lock mouth unit to clamp and process products, has wide application, can adapt to different product sizes for installation, and greatly saves the cost of making fixtures, only needs to fit the corresponding position of the product with the boss, and pass through the cylinder Drive the pull rod and then drive the expansion part to realize the retraction movement of the chuck, and then the locking of the product can be realized. The locking process is simple and fast, which improves the processing efficiency.

detailed description

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the implementation modes are not limitations of the utility model.

As shown in Figures 1 to 3, an elastic clamping fixture for mobile phone case production includes a base 1, a cylinder 2 and a support column 3 are installed on the base 1, one end of the support column 3 is fixed to the base 1, and the other end is connected to the base plate 4 connection, the substrate 4 is provided with a through hole, and the pull rod 21 of the cylinder 2 passes through the through hole to connect with the elastic lock mouth unit 5 for clamping the processed product. The elastic lock mouth unit 5 includes a chuck and an expansion member 51. Expansion hole 52, expansion member 51 is arranged in expansion hole 52, expansion member 51 is fixedly connected with the end of tie rod 21 facing away from cylinder 2, the chuck includes installation part 53 and clamping part 54, and clamping part 54 is longitudinally provided with groove 55 A boss 56 is provided on one end surface of the opening of the clamping portion 54 . The utility model has a simple structure, adopts the elastic lock mouth unit 5 to clamp and process products, has a wide range of uses, can adapt to different product sizes for installation, and greatly saves the cost of making fixtures. It only needs to fit the corresponding position of the product with the boss 6, The cylinder 2 drives the pull rod 21 and then drives the expansion member 51 to realize retraction of the collet, so as to realize the locking of the product. The locking process is simple and fast, and the processing efficiency is improved.

The connection between the installation part 53 and the clamping part 54 is provided with rounded corners, which reduces the stress acting on the connection between the installation part 53 and the clamping part 54 when the clamping part 54 expands, and improves the durability of the chuck.

The quantity of the elastic lock mouth unit 5 is 4, and a plurality of processed products are clamped at the same time, and the processing is performed at the same time, so as to improve the processing efficiency.

The longitudinal section of the expansion member 51 is an isosceles trapezoid, and the expansion hole is a tapered hole, which reduces the pressure on the inner wall of the expansion hole 52 when the expansion member 51 moves in the expansion hole 52, so that the force on the inner wall of the expansion hole 52 is evenly distributed and stable. Sex is better.

The number of support columns 3 is four, which are respectively arranged at the four corners of the base 1, so as to make the support more stable, have better stability during processing, and reduce deviation.

The raised height of the boss 56 is 2 mm, which should not be too high, so as to reduce the difficulty of clamping, improve the efficiency of clamping, and reduce the processing steps of the reserved processing groove corresponding to the processed product and the boss 514, improve the processing efficiency and reduce the processing cost.

The working principle of the utility model is:

When preparing to process the mobile phone case, install the mobile phone case with the groove corresponding to the boss 56 on the clamping part 54, and when the cylinder 2 pulls the pull rod 21 downward, the expansion part 51 connected with the pull rod 21 will push the clamp part 54 Stretched, the boss 56 is closely attached to the groove inner wall of the mobile phone case, and the mobile phone case is locked on the clamping part 54. After the processing is completed, when the pull rod 21 moves upward, the clamping part 54 returns to its original shape by its own elastic force, loose Unlock the mobile phone case locked on the clamping part 54.

The above-mentioned embodiment only expresses one implementation mode of the utility model, and its description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
