DETAILED DESCRIPTION
[0031] The present invention will be described in further detail below with reference to the accompanying drawings. Like components are denoted by like reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.
[0032] The utility model discloses a fixture for plasma spraying, referring to Figure 1 and Figure 2 The clamp mainly includes a base 1, a fixed frame 2 fixed on the top of the base 1 and multiple groups of clamping structures 3 arranged in the fixed frame 2. The number of clamping structures 3 can be determined according to the length of the target material. Each group of clamping structures 3 is composed of two arc-shaped clamping plates 31. The arc-shaped clamping plates 31 used in this scheme may have different shapes. Clamping plates 31 of different shapes can be selected according to actual conditions. The sides of the clamping plates 31 that are away from each other are connected through a driving component 32. The driving component 32 specifically includes a driving cylinder 321 horizontally fixed on both sides of the fixed frame 2, and the output shaft of the driving cylinder 321 is horizontally fixed to the side of the clamping plates 31 that are away from each other. When the driving cylinder 321 is working, its output shaft will push the clamping plates 31 closer or farther away from each other, thereby clamping or releasing the target material. In order to further protect the target material and prevent it from being damaged during the clamping process, an arc-shaped rubber pad 6 is bonded to the side where the clamping plates 31 are close to each other. The rubber pad 6 not only increases the friction between the clamping plates 31 and the target material, but also effectively buffers the clamping force of the clamping plates 31 on the target material, thereby ensuring that the target material always remains stable and undamaged during the spraying process.
[0033] Reference Figure 1 and Figure 3A fixing assembly 4 is provided at the bottom of the fixing frame 2, and the fixing frame 2 is supported and fixed by the fixing assembly 4. The fixing assembly 4 includes a plurality of fixing rods 41 fixed to the bottom of the fixing frame 2, and a connecting rod 42 is provided between the plurality of fixing rods 41. The two ends of the connecting rod 42 are horizontally fixed to the fixing rod 41. This design enables the entire clamp to maintain structural stability and integrity when subjected to a large clamping force or external impact force. A telescopic spring 43 is vertically fixed to the top of the connecting rod 42. One end of the telescopic spring 43 is fixed to the top of the connecting rod 42, and the other end is fixed to the bottom of the fixing frame 2. When the clamp is subjected to external impact or vibration, the telescopic spring 43 can act as a buffer, thereby further protecting the target material and the clamp from damage. At the same time, the telescopic spring 43 can also absorb the slight deformation generated during the clamping process to a certain extent, ensuring the stability and accuracy of the clamping. A plurality of guide rails 5 are provided on the top of the base 1, and a slider 7 matching the guide rail 5 is fixed to the bottom of the fixing rod 41. The slider 7 is connected to the guide rail 5 by sliding, so that the entire clamp can be easily adjusted on the base 1. This design greatly improves the flexibility and applicability of the clamp, allowing staff to accurately adjust the clamp according to actual needs. The slider 7 is provided with a locking mechanism 8, which is used to lock the position of the slider 7 and the top structure. The locking mechanism 8 includes a plurality of positioning holes 81 provided in the guide rail 5, and the slider 7 is provided with positioning holes 81 of the same size. The positioning holes 81 are provided with threads. By threading the locking bolt 82, the slider 7 can be firmly locked to any position on the guide rail 5. This design not only ensures the position accuracy and stability of the clamp after adjustment, but also effectively prevents position deviation caused by accidental touch or vibration. The end of the guide rail 5 is provided with an anti-slip pad 10. The anti-slip pad 10 can effectively prevent the slider 7 from accidentally moving out of the guide rail 5 during the adjustment process, thereby ensuring the safety and reliability of the entire clamp. At the same time, the anti-slip pad 10 can also reduce the friction loss between the slider 7 and the guide rail 5 to a certain extent, extending the service life of the clamp. An auxiliary handle 9 is provided on the fixed frame 2. The specific position and shape of the auxiliary handle 9 can be designed according to actual needs to ensure that it is ergonomic and easy for the staff to hold. By providing the auxiliary handle 9, the staff can easily move the entire clamp, thereby improving work efficiency and operating comfort.
[0034] Working principle: The utility model is a fixture for plasma spraying. When in use, the staff first places the target material in the fixed frame 2 and makes it located between the two sets of clamping structures 3. Then, by controlling the operation of the driving cylinder 321, the clamps 31 are brought close to each other and clamp the target material. The rubber pad 6 plays a role in protecting the target material and preventing it from slipping during the clamping process. During the spraying process, when the position needs to be adjusted, the staff controls the clamp to move on the guide rail 5 through the auxiliary handle 9 and then locks it. When the spraying is completed, the driving cylinder 321 is controlled again to make the clamps 31 move away from each other, thereby releasing the target material.
[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
