[0002] UV testing generally refers to ultraviolet (UV) testing, which is a test method used to evaluate the durability and stability of materials, products or coatings under ultraviolet light irradiation. Ultraviolet light is a part of sunlight, which can cause aging of many materials, such as plastics, paints, textiles and rubbers, etc. Long-term exposure to ultraviolet light may cause discoloration, fading, strength reduction, cracking and other problems of materials. When performing UV testing, special UV aging test boxes or accelerated aging equipment are generally used, which can simulate the ultraviolet light radiation in the natural environment and the possible changes in temperature and humidity conditions. By controlling these factors, the aging effect of materials after years of outdoor exposure can be reproduced in a short time, so as to evaluate their ultraviolet resistance. In UV testing, a clamp is usually used to clamp the test piece;

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below, obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0023] The embodiments of the present application will be described in detail below. Figs. 1-3 The UV testing machine special fixture of the embodiments of the present application will be described in detail.

[0024] Embodiment:

[0025] A special fixture for UV testing machine, comprising:

[0026] The bottom plate 1 is provided with a plurality of test slots 2 on the upper surface, and support legs 14 are fixedly installed at the bottom of the four corners of the bottom plate 1. The support legs 14 improve the stability of the bottom plate 1. The middle of the test slot 2 is slidably connected with an extrusion block 3. The first spring 4 is arranged between the extrusion block 3 and the bottom of the bottom plate 1. The first spring 4 enables the extrusion block 3 to automatically reset. The first clamping groove 5, the second clamping groove 6 and the third clamping groove 7 are sequentially arranged from top to bottom on the left and right sides of the extrusion block 3. The first clamping groove 5 and the third clamping groove 7 are the same size. The middle of the left and right sides of the test slot 2 is slidably connected with a baffle 8. The second spring 9 is arranged between the baffle 8 and the inner wall of the bottom plate 1. The second spring 9 enables the baffle 8 to automatically reset. The connecting rod 10 is fixedly installed on the lower wall of the baffle 8, and the lower end of the connecting rod 10 is in contact with the outer wall of the extrusion block 3.

[0027] When the workpiece needs to be tested by UV, the workpiece is first placed in the test slot 2. At this time, the workpiece pushes the extrusion block 3 downward. The extrusion block 3 moves downward under force. In this process, the connecting rod 10 located in the third clamping groove 7 moves out of it and enters the second clamping groove 6. Because the second clamping groove 6 is deeper, the two connecting rods 10 move inward and towards each other. The baffle 8 located on one side of the connecting rod 10 moves along the track and moves inward and towards each other at the same time, thereby moving the baffle 8 above the workpiece and completing the clamping of the workpiece. When the workpiece needs to be taken out, the workpiece only needs to be continuously pressed downward. At this time, the connecting rod 10 located in the second clamping groove 6 moves out of it and enters the first clamping groove 5. The baffle 8 no longer blocks the workpiece, thereby facilitating the removal of the workpiece. After the workpiece is removed, the extrusion block 3 is rotated and pressed downward to reset it. Compared with the prior art, the present case has the following advantages: 1. Only the bottom plate enables the workpiece to directly contact with the UV light; 2. The structure is simple and easy to install.

[0028] The fixed rod 11 is fixedly installed in the bottom plate 1. The limiting sliding block 12 is fixedly installed on the lower wall of one side of the fixed rod 11. The limiting sliding groove 13 is formed on the upper surface of the extrusion block 3. The limiting sliding block 12 is slidably connected in the limiting sliding groove 13.

[0029] Working principle:

[0030] When the workpiece needs to be tested by UV, the workpiece is first put into the test groove 2, at this time the workpiece pushes the extrusion block 3 downward, the extrusion block 3 is forced to move downward, in the process, the connecting rod 10 in the third clamping groove 7 is moved out of it and into the second clamping groove 6, because the second clamping groove 6 is deeper, so that the two connecting rods 10 move inward and towards each other, the baffle 8 on one side of the connecting rod 10 moves along the track and moves inward and towards each other at the same time, so as to move the baffle 8 above the workpiece and complete the clamping of the workpiece, when the workpiece needs to be taken out, the workpiece only needs to be pressed downward, at this time the connecting rod 10 in the second clamping groove 6 is moved out of it and into the first clamping groove 5, the baffle 8 no longer blocks the workpiece, so as to facilitate the taking out of the workpiece, after the workpiece is taken out, the extrusion block 3 is rotated and pressed downward to reset it, the case has the following advantages compared with the traditional technology: 1. only with the bottom plate, the workpiece can be directly contacted with the UV light; 2. simple structure, easy to install.

[0031] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalent ones; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
