[0034] The utility model aims to provide a device which can assist in detecting the hardness of shaft parts.

[0035] To achieve the above objectives, the present invention provides the following technical solutions:

[0036] See also Figure 1, this embodiment provides a universal hardness auxiliary detection device, which is installed on the lifting screw 02 of the hardness tester 01 and is used to fix the shaft to be measured 03 on the working platform 04 at the top of the lifting screw 02, including: a support connecting plate assembly, a sliding support assembly and a fixed support 300; the support connecting plate assembly can be movably mounted on the outer circumference of the lifting screw 02 along the axis of the lifting screw 02, and the support connecting plate assembly is perpendicular to the lifting screw 02; the sliding support assembly can be movably mounted on the support connecting plate assembly; the fixed support 300 is installed on the top of the working platform 04, and is used to cooperate with the sliding support assembly to fix and support the shaft to be measured 03.

[0037] Specifically, when it is necessary to test the hardness of the shaft, the support connecting plate assembly can be first installed on the lifting screw 02 of the hardness tester 01, and the height of the support connecting plate assembly can be adjusted at the same time so that the height of the sliding support assembly mounted on the support connecting plate assembly is consistent with the height of the lifting screw 02, so as to prevent the shaft 03 to be tested from tilting, and at the same time, the sliding support assembly can be moved according to the length of the shaft 03 to be tested to achieve a better support effect; in this way, the hardness on the circumference of the shaft 03 to be tested can be conveniently tested on the hardness tester 01.

[0038] Preferably, the support connecting plate assembly includes: a connecting sleeve 110, a support plate 120 and a fixed sleeve 130; the connecting sleeve 110 is movably mounted on the outer periphery of the lifting screw 02; the support plate 120 is detachably mounted to one side of the connecting sleeve 110 for supporting the sliding support assembly; the fixed sleeve 130 is mounted on the outer periphery of the lifting screw 02 and is located on the lower side of the connecting sleeve 110, and an internal thread that cooperates with the outer periphery of the lifting screw 02 is provided inside the fixing sleeve 130, and the fixing sleeve 130 is used to prevent the connecting sleeve 110 from sliding down.

[0039] Specific as Figure 1 As shown, the connecting sleeve 110 is a plate-like structure with a through hole in the middle, and the diameter of the through hole is the same as the outer diameter of the lifting screw 02, and the support plate 120 is installed to one side of the connecting sleeve 110. The height of the support plate 120 in the vertical direction is adjusted by adjusting the position of the connecting sleeve 110 on the lifting screw 02, and then the height of the sliding support assembly is adjusted, so as to ensure the level of the shaft 03 to be measured, which is convenient for the hardness test of the shaft 03 to be measured; at the same time, a fixing sleeve 130 is also provided on the outer circumference of the lifting screw 02, and the middle part of the fixing sleeve 130 is provided with an internal thread matching the external thread of the lifting screw 02, and the fixing sleeve 130 can be stably screwed on the lifting screw 02. In this embodiment, the fixing sleeve 130 is installed on the lower side of the connecting sleeve 110, and the connecting sleeve 110 is fixedly supported 300 to prevent the connecting sleeve 110 from sliding down.

[0040] Preferably, the sliding support assembly includes a sliding block 210 and a support block 220 . The sliding block 210 is movably mounted on the outer periphery of the support plate 120 . The support block 220 is located on the upper side of the support plate 120 and is connected to the sliding block 210 .

[0041] Furthermore, the sliding support assembly can move on the support plate 120 to adapt to different lengths of the shaft 03 to be measured. Specifically, the sliding support assembly moves through the sliding block 210, and the shaft 03 to be measured is limited and fixed by the support block 220. The support block 220 is connected to the sliding block 210, and the sliding block 210 is sleeved on the outer circumference of the support.

[0042] In another embodiment, the sliding block 210 can be selected as a slider, and correspondingly, the support plate 120 can be selected as a linear guide rail. Of course, the selection of the sliding block 210 and the support plate 120 can be appropriately adjusted according to actual needs, and this article does not make specific restrictions.

[0043] Preferably, a stopper is provided at the end of the support plate 120 facing away from the connecting sleeve 110 to prevent the sliding block 210 from moving out of the support plate 120 .

[0044] In another embodiment, a retaining member may be provided at one end of the support plate 120 away from the connecting sleeve 110 , so as to prevent the sliding block 210 from moving out of the support plate 120 during movement.

[0045] Preferably, the upper ends of the support block 220 and the fixed support 300 are both of the same V-shaped structure.

[0046] In this embodiment, the upper end surfaces of the support block 220 and the fixed support 300 are both set to a V-shaped structure, and in order to be able to more stably support the shaft to be measured 03, the V-shaped angles of the two are the same; similarly, in order to be able to better adapt to supporting shafts to be measured 03 with different diameters, multiple support blocks 220 and fixed supports 300 with different V-shaped angles can be prepared, and when replacing different shafts to be measured 03, the support block 220 and the fixed support 300 can be replaced at the same time.

[0047] Preferably, the support plate 120 is a long strip-shaped plate structure with a square cross-section. A through hole is provided in the middle of the sliding block 210 for passing through the support plate 120 , and the cross-sectional size of the through hole matches the cross-sectional size of the support plate 120 .

[0048] In this embodiment, the support plate 120 is configured as a plate-like structure with a square cross-section, and in order to be able to support the longer shaft 03 to be measured, the support plate 120 is configured as a long strip structure. Correspondingly, the through hole in the middle of the sliding block 210 is also configured as a square hole. The size of the hole is slightly larger than the cross-sectional area of ​​the support plate 120, which satisfies the requirement that the sliding block 210 can move smoothly on the support plate 120 and will not slide on the support plate 120 at will.

[0049] Of course, the cross-sectional shape of the support plate 120 can also be adjusted according to actual conditions, but the corresponding sliding block 210 also needs to be changed accordingly.

[0050] Preferably, a plurality of sets of sliding blocks 210 and supporting blocks 220 are provided on the supporting plate 120 .

[0051] It can be understood that in order to increase the stability of the shaft to be tested 03 during hardness testing, multiple sets of sliding blocks 210 and support blocks 220 can be set on the support plate 120; when the hardness of the shaft needs to be tested, the multiple sets of sliding blocks 210 and support blocks 220 can be moved so that they are evenly distributed on the lower side of the shaft to be tested 03, thereby providing stable support for it.

[0052] Preferably, the support plate 120 is mounted to the upper side of the connecting sleeve 110 by two fixing screws.

[0053] Specific as Figure 1 As shown, in this embodiment, the support is connected to the upper side of the connecting sleeve 110 by two fixing screws. Of course, other connection methods can also be selected for the two, which is not specifically limited in this article.

[0054] Preferably, the support plate 120 and the sliding block 210 are made of stainless steel, and the support block 220 and the fixed support 300 are made of ordinary carbon steel.

[0055] It is understandable that the sliding block 210 needs to move back and forth on the support plate 120. Therefore, there will be greater wear between the two due to friction. Therefore, the material of both is stainless steel with good wear resistance, while the support block 220 and the fixed support 300 can be made of different economical and practical carbon steels.

[0056] Preferably, a level is provided on the upper side of the support plate 120 to prevent the support plate 120 from tilting.

[0057] In another embodiment, a level meter can be provided on the upper side of the support plate 120 to determine whether the support plate 120 is tilted. If the support plate 120 is tilted, the position of the sliding block 210 can be changed or the length of the axis 03 to be measured can be shortened.

[0058] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0059] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0060] The above is a detailed introduction to the embodiments provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the method and core concept of the present invention. It should be noted that, for those skilled in the art, without departing from the principles of the present invention, various improvements and modifications may be made to the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
