Description

Technical Field

[0001] The utility model relates to the technical field of Rockwell hardness testers, and specifically relates to a Rockwell hardness tester with an angle adjustment function. Background Technique

[0002] The Rockwell hardness tester is the world's first hardness tester designed based on the Rockwell hardness test principle. It can test the hardness of metals by only contacting the specimen unilaterally. It relies on magnetism to adsorb the Rockwell hardness tester probe on the surface of steel, does not require support for the specimen, and is not inferior to bench Rockwell hardness testers.

[0003] Patent network publication number CN 219284926 U discloses a Rockwell hardness tester, which includes a machine body and a test bench. The test bench is arranged on the machine body. At least two clamping mechanisms for clamping and fixing products are arranged on the test bench. The clamping mechanism includes a support rod, an abutting block and a driving member. The support rod is fixed to the test bench through a fixing component. The abutting block is slidably arranged on the support rod along the direction of approaching or departing from the adjacent abutting block. The abutting block is used to abut against the product, and the driving member is used to drive the abutting block to slide; when testing circular or irregularly shaped products, first place the product on the test bench, and then drive the two abutting blocks to approach each other through the driving member, so that the abutting block abuts tightly against the product, thereby clamping and fixing the product, which is convenient for fixing circular or irregularly shaped products to a certain extent and convenient for testing.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] The present utility model provides a technical solution:

[0025] Embodiment 1:

[0026] Combined with Figures 1 to 2 -3, a Rockwell hardness tester with an angle adjustment function includes a Rockwell hardness tester main body 1. An adjustment mechanism 2 is arranged at the inner bottom of the Rockwell hardness tester main body 1, and a clamping mechanism 3 is arranged at the top of the adjustment mechanism 2.

[0027] The adjusting mechanism 2 includes a lifting column 201. The lifting column 201 is arranged at the inner bottom of the Rockwell hardness tester main body 1. A second positioning plate 29 is fixedly connected to the right side surface of the lifting column 201. A threaded rod 27 is threadedly connected inside the second positioning plate 29. A rotating member 28 is fixedly connected to the bottom of the threaded rod 27. The top of the threaded rod 27 is rotatably connected to a third support frame 26. A support seat 204 is fixedly connected to the top of the third support frame 26.

[0028] Furthermore, a first support frame 22 is fixedly connected to the left side of the bottom of the support seat 204. A first support plate 21 is rotatably connected inside the first support frame 22. A second support frame 23 is rotatably connected to the bottom of the first support plate 21. By arranging the first support plate 21, the purpose of supporting the support seat 204 is achieved.

[0029] Furthermore, a first positioning plate 25 is fixedly connected to the bottom of the second support frame 23. The first positioning plate 25 is fixedly connected to the left side surface of the lifting column 201. By arranging the lifting column 201, the purpose of lifting the support seat 204 can be achieved.

[0030] Furthermore, a support rod 203 is fixedly connected to the top of the lifting column 201. Second support plates 24 are rotatably connected to both sides of the surface of the support rod 203. The second support plates 24 are fixedly connected to the bottom of the support seat 204. By arranging the second support plates 24, the support seat 204 can be further supported. A base 202 is fixedly connected to the bottom of the lifting column 201. The base 202 is fixedly connected to the inner bottom of the Rockwell hardness tester main body 1. By arranging the base 202, a supporting force is formed on the lifting column 201.

[0031] Embodiment 2:

[0032] Refer to Figure 4 , and on the basis of Embodiment 1, it is further obtained that the clamping mechanism 3 includes fixing plates 31. The fixing plates 31 are fixedly connected to both sides of the top of the support seat 204. Adjusting bolts 33 are threadedly connected in the middle of both fixing plates 31. One side of each adjusting bolt 33 is rotatably connected to a clamping plate 32. By simultaneously rotating the adjusting bolts 33 on both sides, the adjusting bolts 33 on both sides can drive the clamping plates 32 on both sides to move towards each other.

[0033] Furthermore, the number of the clamping plates 32 is two. The two clamping plates 32 are symmetrically arranged. By arranging the clamping plates 32, the material to be tested can be clamped and fixed to avoid the phenomenon of deviation of the material to be tested.

[0034] In the actual operation process, when it is necessary to test the hardness of the inclined material itself, the material to be tested can be placed on the top of the support base 204. At this time, by simultaneously rotating the adjusting bolts 33 on both sides, the adjusting bolts 33 on both sides can drive the clamping plates 32 on both sides to move towards each other, so as to clamp and fix the material to be tested and avoid the phenomenon of deviation of the material to be tested.

[0035] Since the material to be tested is inclined, it is necessary to rotate the rotating member 28. The rotating member 28 drives the threaded rod 27 to rotate. And under the supporting force formed by the left supporting plate, the purpose of adjusting the angle of the support base 204 can be achieved, so that the surface of the material to be tested is in a horizontal state, thus avoiding the generation of an inclined force during the test, which may cause damage to the indenter and playing a role in protecting the Rockwell hardness tester main body 1.

[0036] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.
