DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0019] like Figures 1 to 3 The non-stick coating wear test sample fixing device shown in the figure comprises a fixing frame 1, a sliding plate 3 and a detection plate 17. The front and rear side walls of the fixing frame 1 are respectively provided with sliding grooves 2. The sliding plate 3 is slidably connected to the sliding grooves 2. The sliding plate 3 is connected to a universal ball 10. The universal ball 10 abuts against the side walls of the sliding grooves 2. Figure 1As described above, the sliding plate 3 is connected with several groups of universal balls 10 to improve the smoothness of sliding. The upper side of the sliding plate 3 is connected with a fixing plate 8. The fixing plate 8 is provided with a placement groove 11. The detection plate 17 is slidably connected with the placement groove 11, that is, the detection plate 17 can be placed into the placement groove 11. The side wall of the placement groove 11 is provided with an operation groove 18. The fixing frame 1 is connected with a mounting frame 13. The mounting frame 13 is in a U shape. The mounting frame 13 is slidably connected with a sliding rod 14. There are three groups of sliding rods 14. The three groups of sliding rods 14 are jointly connected with a placement plate 16. The placement plate 16 is detachably connected with a weight 15. The weight 15 is slidably connected with the sliding rod 14. As Figure 2 shown, the weight 15 is provided with an opening, so that the increase and decrease of the weight 15 can be completed. The placement plate 16 is connected with a friction plate 12.

[0020] The bottom of the sliding plate 3 is connected with a transition block 7. The transition block 7 is rotatably connected with a pull rod 4. The fixing frame 1 is connected with a connecting frame 9. The connecting frame 9 is in a U shape. The connecting frame 9 is connected with a servo motor 6. The output shaft of the servo motor 6 is fixedly connected with a rotating rod 5. The free end of the pull rod 4 is rotatably connected with the free end of the rotating rod 5. As Figure 3 shown.

[0021] The specific implementation process is as follows:

[0022] When in use, the paint can be applied on the detection plate 17, and the detection plate 17 can be made of a suitable material according to the type of paint. After the paint condenses on the detection plate 17, the detection plate 17 is placed in the placement groove 11. When placing the detection plate 17, the friction plate 12 can be slid upward so that the detection plate 17 can be smoothly placed in the placement groove 11, and the movement of the detection plate 17 is limited by the placement groove 11. After the detection plate 17 is placed in the placement groove 11, the placement plate 16 is released, and the friction plate 12 can conflict with the paint on the surface of the detection plate 17. The horizontal movement of the friction plate 12 and the placement plate 16 is limited by multiple sets of sliding rods 14, so that the placement plate 16 and the friction plate 12 can only move up and down; a weight 15 of corresponding weight is placed on the placement plate 16, and under the action of the gravity of the weight 15, the friction plate 12 and the placement plate 16 further conflict with the paint on the detection plate 17. When the detection plate 17 moves relative to the friction plate 12, it will be subject to the friction between the friction plate 12 and the paint. As the weight of the weight 15 changes, the size of the friction will also change accordingly. After the weight 15 is placed on the placement plate 16, the servo motor 6 can be started, and the servo motor 6 drives the rotating rod 5 to rotate with the output shaft of the servo motor 6 as the axis. The rotating rod 5 rotates and pulls the pull rod 4 to move, thereby driving the sliding plate 3 to slide along the sliding groove 2. As the rotating rod 5 rotates, the rotating rod 5 drives the pull rod 4 and then the pull rod 4 drives the sliding plate 3 to move back and forth left and right, thereby making the detection plate 17 slide left and right with the sliding plate 3. The reciprocating movement of the detection plate 17 causes friction between the paint applied on the detection plate 17 and the friction plate 12. The servo motor 6 is controlled to drive the rotating rod 5 to rotate at a suitable speed, thereby controlling the number of reciprocating movements of the detection plate 17. After the measurement is completed, the operating slot 18 is used to facilitate the insertion of a clamping tool or the detection plate 17 is quickly removed by hand, thereby evaluating the wear resistance of the paint on the detection plate 17; subsequently, the detection plate 17 coated with different paints can be placed in the placement slot 11 for detection, or the detection plate 17 coated with the same paint can be placed in the placement slot 11, and the weight of the weight 15 is changed to complete a comprehensive detection.

[0023] The technical solution can place the test plate 17 coated with paint on the sliding plate 3, and the paint and the friction plate 12 are rubbed by reciprocating the sliding block to complete the wear test. The friction between the friction plate 12 and the paint can be adjusted by adding the weight 15, so that different friction forces can be applied to paints with different uses to detect whether they can reach the wear resistance required by the device. Different friction forces can also be applied to the same kind of paint to detect the wear resistance criticality of the paint, which greatly improves the applicability of the device, is convenient to adjust, has a simple overall structure, is easy to use, and greatly improves practicality; through the servo The motor 6 drives the rotating rod 5 to rotate, which can drive the pull rod 4 to drive the sliding plate 3 to move left and right. No manual operation is required, which is convenient for testing the wear resistance of the paint; the sliding plate 3 is provided with a universal ball 10 to reduce the friction between the sliding plate 3 and the sliding groove 2, thereby improving the sliding stability and service life of the sliding plate 3; multiple sets of sliding rods 14 can ensure that the friction plate 12 will not move with the movement of the sliding plate 3; the side wall of the sliding groove 2 is provided with an operating groove 18, which makes it convenient for the staff to take the detection plate 17 out of the placement groove 11, and to replace different detection plates 17 for the purpose of detecting different paints.

[0024] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
