Abstract
The utility model discloses a universal tool for Rockwell hardness detection. The universal tool comprises support platforms and a sleeve, wherein two sides of the sleeve are provided with a horizontal slider rod respectively, each horizontal slider rod is provided with one adjusting cylinder, the bottom of each adjusting cylinder is sleeved on the corresponding horizontal slider rod and can slide along the horizontal slider rod; the upper part of each adjusting cylinder is hollow and is provided with the support platform 1 through bolts, and the inner all of each adjusting cylinder is provided with inner threads; the adjusting range of the transverse distance of the two support platforms 1 is 50-400mm; and the height adjusting range of each support platform is 130-160mm. According to the utility model, the problem of dimensional limitation of a worktable of a hardness tester is solved effectively, a member to be detected is enlarged in detection range and increased in stability, and the universal tool can be used for precisely and effectively measuring the Rockwell hardness of non-standard members and standard members of various shapes and specifications.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of frock, and particularly a kind of Rockwell's hardness detects universal fixture.
Background technology
Rockwell hardometer is used for measuring the material Rockwell hardness number, can test from very soft to very hard almost whole common metal materials, and range of application is very wide.But because the restriction of its testing machine worktable scope, for some out-of-shapes, larger-size sample, and when requiring to measure the hardness of the local locations such as test piece end, the limitation of Rockwell hardometer just displays.For example length surpasses the bolt of 200mm, when needing to measure its straight-line hardening hardness, because this bolt length is longer, the testing machine worktable is less than normal, can only support test specimen one end, the other end is owing to be suspended in the air or artificially hold with hand steered, unbalance stress in the time of all can causing test to load, not only the result is affected greatly, also can cause pressure head impaired.In addition, also have some out-of-shape test specimens, for example in the middle of thin or middle thin two pluckings or pluckings thin test specimens in thick two etc., when requiring the Rockwell's hardness at a certain position of test, can't on the testing machine worktable, steadily place because of it, cause hardness test to implement.
Summary of the invention
Defective or deficiency for above-mentioned prior art existence, the purpose of this utility model is, provide a kind of Rockwell's hardness to detect universal fixture, this frock efficiently solves hardness tester bed dimension limitation problem, improve sensing range and the stationarity of detected member, can accurately effectively measure the non-standard component of various shape specification and the Rockwell's hardness of standard component.
In order to reach above purpose, the utility model adopts following technical solution:
A kind of Rockwell's hardness detects universal fixture, it is characterized in that comprise brace table and sleeve, the sleeve both sides are equipped with horizontal litter, is equipped with an adjustment barrel on each horizontal litter, and the bottom of adjustment barrel is enclosed within on the horizontal litter and can slides along horizontal litter; Adjustment barrel top hollow and inwall have internal thread, and the top of adjustment barrel is equipped with brace table 1 by bolt.
Further, the lateral separation range of adjustment of two described brace tables 1 is 50mm～400mm.
Further, the height adjustment range 130mm of described brace table 1～160mm.
The utility model beneficial effect:
1, broken the limitation that conventional Rockwell hardometer detects, removed the strict demand of Rockwell hardometer to detected sample dimensions, position and specification, the hardness that solved irregular, greatly enhances part detects.
2, adopt simultaneously two brace tables, the adjustability of two brace table lateral separations makes the length of detected member or diameter range expand 400mm to, stationarity, horizontality when vertically the adjusting of height and levelness has guaranteed loading have improved sensing range and the degree of accuracy of testing machine.
3, the utility model is easy to operate, and adjustability is good, both can increase work efficiency, and can guarantee that again measurement data is accurately reliable.

Below in conjunction with the drawings and specific embodiments the utility model is further explained explanation.
Embodiment
As shown in Figure 1, Rockwell's hardness of the present utility model detects universal fixture, comprises brace table 1 and sleeve 5, and sleeve 5 both sides are equipped with horizontal litter 3, be equipped with an adjustment barrel 2 on each horizontal litter 3, the bottom of adjustment barrel 2 is enclosed within on the horizontal litter 3 and can slides along horizontal litter 3; Adjustment barrel 2 top hollows and inwall have internal thread, and the top of adjustment barrel 2 is equipped with brace table 1 by bolt 4.
Material of the present utility model is 45 steel after the modifier treatment.
As shown in Figure 2, be an embodiment of the present utility model.The lateral separation adjustable extent of two brace table 1 is 50mm～400mm, and the height of brace table 1 is regulated according to the height of testing machine worktable, and range of adjustment 130mm～160mm steadily places to guarantee the detected member level.
The utility model in use, sleeve 5 is packed on the main shaft of testing machine, size and dimension according to detected member, the lateral separation that slidable adjustment cylinder 2 is regulated two brace tables 1 on horizontal litter 3, after the lateral attitude fixes, by the relative distance between turn bolt 4 adjusting brace tables 1 and the adjustment barrel 2, thereby the height of the brace table 1 of regulating, guarantee that brace table 1 and testing machine worktable are in the same level position, place the detected member two ends respectively on brace table 1 and the testing machine worktable this moment, the starting characteristics test machine loads in the detection position of appointment, measures the Rockwell's hardness at this position.
The utility model is applicable to all kinds of component of machine Rockwell hardness tests, the Rockwell's hardness that is particularly useful for elongated rod shape in irregular shape, rectangular constitutional detail detects, the length range of test specimen can be increased to 400mm, and the detected value scope is 25HRC～65HRC, and accuracy rating is ± 1%.
