Description

Technical Field

[0001] This utility model belongs to the field of paint surface abrasion resistance testing technology, specifically relating to a device for testing the abrasion resistance of paint surfaces on wood products. Background Technology

[0002] After wood products are processed and shaped, they often need to be painted to improve their moisture resistance, wear resistance, and aesthetics. To ensure good wear resistance, the paint surface needs to be tested. The procedure involves clamping and fixing the wood product in a special testing device, placing the friction head against the paint surface, and then moving the wood product back and forth in a linear motion. During this process, the paint surface and the friction head rub against each other continuously. After a period of time, the wood product is removed, and the degree of wear on the paint surface is observed to evaluate the wear resistance of the paint surface.

[0003] When existing testing machines fix wooden products, the common method is to limit the position of the wooden products by clamping. However, different wooden products have different thicknesses. When the height of the clamp is higher than the thickness of the wooden product, it will cause certain mechanical interference to the friction of the friction head, thus causing some inconvenience to the wear resistance test. Therefore, it is necessary to design a new wear resistance testing device to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a wood product paint surface abrasion resistance testing device to solve the problem of mechanical interference between the clamp and the friction head in the existing testing device mentioned in the background art.

[0025] Base box 100, connecting seat 200 disposed on top of base box 100;

[0026] The clamping assembly 300 includes a placement platform 301 slidably connected to the surface of the connecting seat 200, a support plate 302 vertically connected to one end of the placement platform 301, a fixing piece 308 fixed to one side of the support plate 302, a base plate 309 fixed to one end of the placement platform 301 and located directly below the fixing piece 308, a lead screw 3010 fixed to the surface of the base plate 309 and slidingly passing through the fixing piece 308, two screw sleeves 3011 threaded to the surface of the lead screw 3010 and distributed on the upper and lower sides of the fixing piece 308, two side rails 306 disposed inside the placement platform 301 and fixed to the support plate 302, a clamping plate 304 slidably connected between the side rails 306, and a clamping plate 304 formed on the placement platform 301. The surface of the 01 table has a top groove 303 through which the clamping plate 304 passes. The tops of the abutment plate 302 and the clamping plate 304 are flush. The wooden product can be placed on the surface of the table 301 with one end abutting against the abutment plate 302. Then, the height of the fixing plate 308 and the abutment plate 302 can be adjusted by rotating the two rotating sleeves 3011 so that the abutment plate 302 is slightly lower than the wooden product. Since the abutment plate 302 is fixedly connected to the side rail 306 and the clamping plate 304 is connected to the side rail 306, the clamping plate 304 moves up and down synchronously with the abutment plate 302. In this way, the abutment plate 302 and the clamping plate 304 are lower than the wooden product and will not mechanically interfere with the friction head 600.

[0027] The friction head 600, which is set on top of the base box 100 and above the clamping assembly 300, continuously rubs against the wooden product to conduct wear resistance tests.

[0028] In this embodiment, preferably, the top of the lead screw 3010 has a T-shaped structure to prevent it from slipping off. The support plate 302 is in contact with one end of the surface of the placement platform 301. One end of the placement platform 301 is provided with a through groove 3014 for the side rail 306 to slide through, so that the side rail 306 can move stably up and down with the support plate 302.

[0029] In this embodiment, preferably, the clamping assembly 300 further includes a threaded rod 307 rotatably connected to one side of the abutment plate 302. The threaded rod 307 is threadedly connected to the clamping plate 304, and its outer end extends out of the placement platform 301. The clamping assembly 300 also includes a handle 3012, which is fixed to the outer end of the threaded rod 307. By rotating the handle 3012, the threaded rod 307 is driven to rotate, thereby driving the clamping plate 304 to move along the side rail 306. The wooden product is firmly clamped by the clamping plate 304 and the abutment plate 302.

[0030] In this embodiment, preferably, the clamping assembly 300 further includes two fixing rods 3013 fixed inside the placement platform 301. The fixing rods 3013 are slidably inserted into the ends of the side rails 306 to further improve the stability of the lifting and moving of the side rails 306.

[0031] In this embodiment, preferably, the clamping assembly 300 further includes a movable door 305 rotatably connected to the front surface of the placement platform 301. The top of the movable door 305 is connected to the placement platform 301 by a torsion spring, which can open the movable door 305 and then clean up the debris that has fallen into the placement platform 301.

[0032] In this embodiment, preferably, a top frame 400 is provided on the top of the bottom box 100, a friction rod 500 is connected to one side of the top frame 400, and a friction head 600 is connected to the bottom end of the friction rod 500 to limit and fix the friction head 600.
