[0001] This application relates to the field of tooling testing, and in particular to a hardness testing tooling. Background Art

[0002] A hardness testing tooling is a tool or device used for various hardness tests. Different types of hardness tests require different toolings, which are usually designed to apply standardized loads or geometries in order to measure hardness characteristics such as the compressive resistance or puncture resistance of materials.

[0003] For example, the hardness testing tooling with the publication number 202322200062.4 still has the following deficiencies in actual use:

[0004] When the hardness testing tooling of the above patent is actually used, it is unable to perform hardness tests on toolings that require multi-angle hardness tests. When performing a hardness test, the best test state is when the test surface is perpendicular to the test head. However, the edges of some toolings are irregular shapes, which makes this device unable to achieve the best test state for hardness testing, resulting in a poor test state. Utility Model Content

[0038] The following is combined with the attached Figures 1-5Further details of this application are provided below.

[0039] An embodiment of this application discloses a hardness testing tooling.

[0040] Embodiment 1

[0041] Referring to Figure 1 , a hardness testing tooling includes a device base plate 1. A sliding control mechanism 2 is arranged on the top of the device base plate 1, and a vertical adjustment mechanism 4 is arranged on the top of the device base plate 1;

[0042] With the above settings, the staff places the device base plate 1 flat on the workbench and prepares to perform a hardness test on the tooling.

[0043] Referring to Figure 2 , 3, the sliding control mechanism 2 includes a slide rail 21 fixedly connected to the top of the device base plate 1. The slide rail 21 is in the shape of a dovetail. A dovetail through groove is formed in the side wall of the sliding base plate 22. The sliding base plate 22 movably penetrates through the dovetail through groove formed in the side wall of the sliding base plate 22, so that the slide rail 21 is slidably connected to the sliding base plate 22. The top side wall of the sliding base plate 22 is fixedly connected to the bottom side wall of the side plate 23, and the top of the sliding base plate 22 is fixedly connected to the bottom of the connecting plate 24. The sliding control mechanism 2 further includes a disc 25 fixedly connected to the side wall of the connecting plate 24. One side wall of the connecting plate 24 close to the side plate 23 is fixedly connected to one side wall of the side plate 23 close to the connecting plate 24. One side of the disc 25 away from the connecting plate 24 is fixedly connected to one side of the ring 26 close to the disc 25. The outer wall of the ring 26 is slidably connected to the inner wall of the workpiece to be tested 3, so that the workpiece to be tested 3 is sleeved on the outer wall of the ring 26. The outer wall of the disc 25 is fixedly connected to one side of a plurality of limit members 27 close to the disc 25. An internal thread hole is formed through the top of the sliding base plate 22. A threaded column 28 is threaded through the internal thread hole formed through the top of the sliding base plate 22. The top of the threaded column 28 fixedly penetrates through the middle of the knob 29, so that the threaded column 28 and the middle of the knob 29 are fixedly connected through penetration.

[0044] With the above settings, the staff first sleeved the workpiece to be tested 3 on the outer wall of the ring 26, and then pushed the sliding base plate 22 according to the actual hardness test requirements. The sliding base plate 22 will drive the connecting plate 24 to move horizontally. The connecting plate 24 will drive the disc 25 to move horizontally. The disc 25 will drive the workpiece to be tested 3 to move horizontally, so that the position on the edge of the workpiece to be tested 3 that needs to be subjected to hardness detection is located directly below the test pen 413. Then the staff rotates the knob 29. The knob 29 will drive the threaded column 28 to rotate. The threaded column 28 will move vertically downward. The bottom of the threaded column 28 will be in contact with the top of the device base plate 1, thus jacking up the sliding base plate 22. Since the slide rail 21 is in the shape of a dovetail, the sliding base plate 22 will be fixed after being jacked up vertically upward, thus preventing the sliding base plate 22 from shaking by itself.

[0045] Referring toFigure 4 , 5, the vertical adjustment mechanism 4 includes a horizontal block 410. The horizontal block 410 is made of plastic material and has a certain toughness. A circular through-hole is formed through the top of the horizontal block 410. The fixing ring 411 is clamped in the circular through-hole formed through the top of the horizontal block 410. The fixing ring 411 is made of rubber material. A vertical slit 412 is formed non-through on the side of the horizontal block 410 away from the connecting block 49. A circular through-hole is formed through the top of the fixing ring 411. The test pen 413 is slidably connected in the circular through-hole formed through the top of the fixing ring 411. The rotating screw 414 is non-through threadedly connected to the side wall of the horizontal block 410. The rotating screw 414 threadedly penetrates through the vertical slit 412. Thus, by rotating the rotating screw 414, the two sides of the vertical slit 412 can be clamped towards the middle, so that the gap of the vertical slit 412 will be reduced, so that the horizontal block 410 clamps both sides of the fixing ring 411, and finally the fixing ring 411 clamps and fixes the test pen 413.

[0046] Through the above settings, when the workpiece to be tested 3 is located directly below the test pen 413, the worker rotates the handle 48. The handle 48 will drive the turntable 47 to rotate. The rotation of the turntable 47 will drive the threaded rod 45 to rotate. The threaded rod 45 will drive the moving block 46 to move vertically. The moving block 46 will drive the connecting block 49 to move vertically synchronously. The connecting block 49 will drive the horizontal block 410 to move vertically, so that the horizontal block 410 drives the test pen 413 to move to the side close to the workpiece to be tested 3.

[0047] Refer to Figure 4, 5, the vertical adjustment mechanism 4 further includes a support base 41 fixedly connected to the top of the device base plate 1. A square groove 42 is provided at the top of the support base 41. The top of the square groove 42 is fixedly connected to the bottom of the vertical plate 43. The top of the vertical plate 43 is fixedly connected to the bottom of the top cover plate 44. A circular through-hole is provided in the middle of the top cover plate 44. The threaded rod 45 is inserted into the circular through-hole provided in the middle of the top cover plate 44, so that the threaded rod 45 is rotatably connected to the top cover plate 44. The outer wall of the rotating connection between the threaded rod 45 and the top cover plate 44 is a smooth surface, so that the structure is more stable. A cylindrical groove is provided at the bottom of the square groove 42. The lower end of the threaded rod 45 is rotatably and non-penetratingly connected to the cylindrical groove provided at the bottom of the square groove 42, so that the threaded rod 45 is rotatably connected to the square groove 42. The outer wall of the rotating connection between the threaded rod 45 and the square groove 42 is a smooth surface, so that the structure linkage is more stable. A threaded hole is vertically provided at the top of the moving block 46. The middle of the threaded rod 45 threadedly penetrates the threaded hole vertically provided at the top of the moving block 46, so that the moving block 46 is threadedly connected to the threaded rod 45. The outer wall of the moving block 46 fits with the inner wall of the vertical plate 43, so that the moving block 46 is limited by the vertical plate 43, and the moving block 46 can only move vertically. The top of the threaded rod 45 is fixedly connected to the bottom of the turntable 47. The top of the turntable 47 is fixedly connected to the bottom of the handle 48. One end of the moving block 46 away from the threaded rod 45 is fixedly connected to one end of the connecting block 49 close to the moving block 46. One end of the connecting block 49 away from the moving block 46 is fixedly connected to one end of the horizontal block 410 close to the connecting block 49 to perform the movement linkage.

[0048] Through the above settings, when it is necessary to perform a vertical fine adjustment on the test pen 413, the staff first rotates the rotating screw 414 to make the gap of the vertical slit 412 larger. Then, the test pen 413 is slid so that the bottom of the test pen 413 contacts the edge of the workpiece 3 to be measured. When the test pen 413 reaches the designated position, the staff rotates the rotating screw 414. Through the continuous rotation of the rotating screw 414, the gap of the vertical slit 412 will become smaller, the horizontal block 410 will fix the fixing ring 411, and the fixing ring 411 will clamp the side wall of the test pen 413, thereby fixing the test pen 413.

[0049] The implementation principle of a hardness testing tooling in an embodiment of the present application is as follows: By sliding the sliding bottom plate 22 to drive the connecting plate 24 to move horizontally, so that the disc 25 drives the ring 26 to move horizontally, thereby driving the tooling to be tested 3 to move horizontally, enabling the horizontal position of the tooling to be tested 3 to be adjusted according to different detection requirements. Subsequently, rotate the knob 29 to lock the sliding bottom plate 22, and then rotate the handle 48 to drive the turntable 47 to rotate, thereby driving the connecting block 49 to move vertically. Then, drive the horizontal block 410 to move vertically synchronously through the connecting block 49, thereby driving the test pen 413 to move vertically. Then, through the vertical adjustment of the test pen 413, it is in perpendicular contact with the outer wall of the tooling to be tested 3, so as to achieve the best hardness testing effect.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
