[0003] In the property test of building boards, the detection of board surface hardness has always been the top priority. The current method of testing the board surface hardness is to place the board on a testing table, press the product surface with a replay head, and judge the hardness of the product through the pressing data of the detection sensing element at the bottom of the pressure table to determine whether the product is qualified.

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] refer to Figure 1-6 A tooling table 1 is provided, on which a loading part 2, a pressing part 3 and a testing part 4 are respectively provided. The loading part 2 is used to load the plate so that the plate can be transported to the bottom of the testing part 4. The pressing part 3 can fix the surface of the plate to ensure the stability of the plate. The testing part 4 can test the surface of the plate, thereby measuring the hardness value of the plate surface.

[0030] refer to Figure 1-6 The testing part 4 includes a testing linear module 41 fixed in the vertical direction and a punching head 42 fixedly connected to the testing linear module 41. A testing motor for driving the punching head 42 to move in the vertical direction is provided at the top of the testing linear module 41. When the testing motor is started, the punching head 42 will move vertically along the direction of the testing linear module 41.

[0031] refer to Figure 1-6The pressing part 3 includes a pressure platform 31 corresponding to the punching head 42 and a pressure block 32 movably connected to the surface of the pressure platform 31. During the descent of the punching head 42, it will contact the surface of the plate, and the plate will press the pressure block 32 to move downward. A movable cavity is provided in the pressure platform 31, and a pressure sensing component 33 is provided at the bottom end of the movable cavity. When the pressure block 32 moves to a certain position, it will contact the pressure sensing component 33, thereby measuring the hardness of the surface of the plate. A linkage piece 34 is provided at the bottom end of the pressure block 32, and a driving arm 35 is rotatably connected to the linkage piece 34. The movement of the linkage piece 34 will drive the driving arm 35 to rotate. An elastic member 321 is fixedly connected to the bottom end of the pressure block 32, and the elastic member 321 is fixedly connected to the surface of the linkage piece 34, thereby ensuring that the pressure block 32 will not apply a high pressure to the surface of the linkage piece 34 during the descent, thereby playing a buffering role and also making The linkage piece 34 can follow the movement of the pressure-bearing piece. Both ends of the driving arm 35 are provided with sliding grooves 351, and sliding rods 352 are slidably connected in the sliding grooves 351. The sliding rod 352 at one end is rotatably connected to the linkage piece 34, and the sliding rod 352 at the other end slides in the sliding groove 351, thereby forming a biaxial movement, ensuring the rotation direction of the driving arm 35 and forming a grasping claw shape. A sliding platform 37 is provided on one side of the receiving platform, and a sliding groove 371 is provided on the sliding platform 37. The sliding rod 352 extends into the sliding groove 371. A central rotating part 353 is provided at the middle end of the driving arm 35. The central rotating part 353 and the driving arm 35 are rotatably connected to form a lever structure, which ensures that one end of the driving arm 35 can move toward the direction of the pressure platform 31 along the direction of the sliding groove 371 during the descent of the pressure block 32, thereby realizing the linkage effect between the pressure block 32 and the driving arm 35.

[0032] refer to Figure 1-6 A pressing head 36 is fixedly provided at the end of the driving arm 35. When the pressure block 32 moves, the pressing head 36 is driven to move toward the pressure platform 31. The pressing head 36 can clamp and press the surface of the plate. The pressing head 36 is divided into a pressing upper plate 361 and a pressing lower plate 362. The pressing upper plate 361 and the pressing lower plate 362 are fixedly connected by a telescopic rod 363. The telescopic rod 363 is fixedly connected to the sliding rod 352. There are guide surfaces on the pressing upper plate 361 and the pressing lower plate, which can introduce guidance for plates of different thicknesses. The pressing upper plate 361 and the lower plate will gradually press from the side of the plate to the surface of the plate in the process of linkage with the pressure platform 31, thereby fixing the plate in the vertical direction. The existence of the telescopic rod 363 makes the distance between the pressing upper plate 361 and the pressing lower plate 362 adjustable, so that plates of different specifications can be fixed and limited.

[0033] refer to Figure 1-6The feeding part 2 includes a feeding moving module 21, which is connected to the surface of the pressure platform 31 to ensure that the plate can be smoothly transported to the pressure platform 31. The feeding moving module 21 includes a feeding platform 211 and a two-way cylinder 212 fixedly connected to the bottom of the feeding platform 211. The output end of the two-way cylinder 212 is fixedly connected to an adjusting rod 213. The feeding platform 211 is provided with an adjusting slot 214 for the adjusting rod 213 to extend out. One end of the adjusting rod 213 is fixedly connected to an adjusting plate 215. The material moving module 21 also includes a moving block 216, and the two-way cylinder 212 is fixedly connected to the moving block 216. One end of the feeding moving module 21 is fixedly connected to a feeding motor 217. The output end of the feeding motor 217 extends into the feeding moving module 21. When the plate is placed on the feeding table 211, through the adjustment of the two-way cylinder 212, the two adjustment plates 215 can both resist and clamp the side of the plate, thereby ensuring the stability of the plate feeding. The two-way cylinder 212 can adapt to plates of various specifications.

[0034] When using this mechanism, place the plate on the loading platform 211, start the loading motor 217, and then start the two-way cylinder 212. The two-way cylinder 212 drives the adjustment plate 215 to clamp the plate and move it to the pressure block 32 on the pressure platform 31. At this time, the punch head 42 of the test part 4 is started. The punch head 42 is driven by the test motor to press against the surface of the plate. After the pressure on the surface of the plate is applied, it will exert downward pressure on the pressure block 32. The pressure block 32 descends and drives the driving arm 35 to rotate. The driving arm 35 moves on the lever Under the action, it rotates toward the pressure platform 31 and drives the pressing head 36 to approach the side of the plate. The pressing head 36 will press the upper plate 361 and the lower plate 362 on the upper surface and lower surface of the plate respectively under the adjustment of the telescopic rod 363. At this time, the plate is fixed, and the punching head 42 continues to descend to the contact pressure sensing part 33 to measure the hardness value. Then the punching head 42 is lifted, and the driving arm 35 moves away from the pressure platform 31 and makes the pressing head 36 away from the surface of the plate, thereby completing the tooling process for fixing the plate to test the hardness.

[0035] The above embodiments are used to further illustrate the present invention, but the present invention is not limited to these specific implementations. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
