Description

Technical Field

[0001] This utility model relates to the field of PVD fixtures, specifically a PVD fixture that can be quickly assembled and disassembled. Background Technology

[0002] Conventional PVD fixtures are generally assembled into a single structure by welding, which is inconvenient for cleaning and maintenance during use. When some of the mounting teeth are damaged, the entire fixture needs to be replaced, resulting in high maintenance costs. In the few fixtures that are connected by screws, shims are required to prevent loosening of the screws, which reduces installation efficiency.

[0003] Therefore, those skilled in the art have provided a PVD fixture that can be quickly assembled and disassembled to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a PVD fixture that can be quickly assembled and disassembled, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A quick-assembly and disassembly PVD fixture includes a hanging plate. Multiple positioning and mounting slots are evenly distributed around the top of the hanging plate. Elastic hanging teeth are provided inside each positioning and mounting slot. The elastic hanging teeth are connected to the hanging plate via countersunk screws and a locking nut. An elastic groove is provided on the threaded hole inside the locking nut. A bottom annular groove is provided at the bottom of the locking nut. An elastic support member is integrally formed on the locking nut between the bottom annular groove and the elastic groove. The bottom of the elastic support member protrudes from the bottom surface of the locking nut.

[0007] As a further embodiment of this utility model: a shaft hole is provided in the middle of the hanging plate, and keyways are symmetrically provided on the inner wall of the shaft hole.

[0008] As a further embodiment of this utility model: a connecting sleeve is fixedly connected to one end of the shaft hole on the hanging plate, the connecting sleeve is concentric with the shaft hole, and a fixing screw is threadedly connected to the outer circle surface of the connecting sleeve.

[0009] As a further embodiment of this invention, the locking nut is made of a metal with high elasticity.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The connection and fixation of the hanging plate and elastic teeth are achieved by using a lock nut and countersunk screw. It can be assembled and installed according to needs. Each unit can be quickly disassembled and maintained, which is convenient for cleaning the fixture and replacing the elastic teeth, thus improving production efficiency. Moreover, after the lock nut is tightened, under the elastic force of the elastic support at the bottom of the lock nut and the pressing surface, a radial force can be applied to the threaded part of the elastic support in the lock nut, which can play a role in preventing stripping. This eliminates the trouble of adding shims and improves installation efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 In this embodiment of the utility model, a PVD fixture that can be quickly assembled and disassembled includes a hanging plate 1. Multiple positioning and mounting grooves 101 are evenly distributed around the upper part of the hanging plate 1. Elastic hanging teeth 2 are provided inside the positioning and mounting grooves 101. The elastic hanging teeth 2 are connected to the hanging plate 1 by countersunk screws 3 and locking nuts 6. An elastic groove 602 is provided on the threaded hole 601 inside the locking nut 6. A bottom annular groove 603 is provided at the bottom of the locking nut 6. An elastic support member 604 is integrally formed on the locking nut 6 between the bottom annular groove 603 and the elastic groove 602. The bottom of the elastic support member 604 protrudes from the bottom surface of the locking nut 6.

[0019] By adopting the above technical solution, the connection and fixation of the hanging plate 1 and the elastic hanging teeth 2 are achieved by using a locking nut 6 and a countersunk screw 3. They can be combined and installed according to requirements. Each unit can be quickly disassembled and maintained, which is convenient for cleaning the fixture and replacing the elastic hanging teeth 2, thus improving production efficiency. Moreover, after the locking nut 6 is locked, under the elastic force of the elastic support 604 at the bottom of the locking nut 6 and the pressing surface, a radial force can be applied to the threaded part of the elastic support 604 in the locking nut 6, which plays a role in preventing stripping. This eliminates the trouble of adding shims and improves installation efficiency. The elastic hanging teeth 2 are evenly distributed around the periphery of the hanging plate 1, which is convenient for automatic feeding.

[0020] The hanging plate 1 has a shaft hole 102 in the middle, and keyways 103 are symmetrically provided on the inner wall of the shaft hole 102. A connecting sleeve 4 is fixedly connected to one end of the shaft hole 102 on the hanging plate 1. The connecting sleeve 4 is concentric with the shaft hole 102, and a fixing screw 5 is threadedly connected to the outer circle of the connecting sleeve 4. The support shaft can be inserted into the shaft hole 102 and the connecting sleeve 4, and locked by pressing with the fixing screw 5. The keyway 103 is used for orientation of automatic feeding.

[0021] The locking nut 6 is made of a metal with high elasticity, which ensures that the elastic support 604 is in the reset state when the locking nut 6 is not under force, thus ensuring that it can be used multiple times.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
