Description

Technical Field

[0001] The utility model relates to the field of hardness tester measurement, in particular to a long-axis type auxiliary tooling based on a hardness tester. Background Art

[0002] Hardness refers to the ability of a material to locally resist the indentation of a hard object into its surface and is an index for comparing the hardness of materials. Measuring the hardness of materials requires the use of a hardness tester.

[0003] Chinese Patent with publication number CN217654938U discloses a portable Brinell hardness tester, including a Brinell hardness tester body. A fixed seat is installed at the bottom end of the inner wall of the Brinell hardness tester body. A plurality of limiting grooves are provided in the inner wall of the fixed seat. A limiting block is slidably embedded in the inner cavity of the limiting groove. The top end of the limiting block is provided with a liftable measuring module. The measuring module includes a lead screw that vertically lifts and a workbench rotatably arranged at the upper end of the lead screw. An elevating component for driving the lead screw to vertically lift is provided on the Brinell hardness tester.

[0004] In the above structure, the workbench can only measure the hardness of flat parts. When the object to be measured is a shaft part, a common method is to remove the workbench installed on the lead screw and then install a workbench with a positioning groove that fits the outer circle of the shaft part to the top of the lead screw. The positioning groove is an arc groove or a V-shaped groove. At this time, the hardness of the outer wall of the shaft part can be measured.

[0005] However, replacing the workbench with a semi-circular groove or a V-shaped groove can only measure the hardness of the outer wall of short shaft parts and cannot measure the outer wall of long shaft parts. Due to the lack of a structure to keep the long shaft part always in a horizontal state, when measuring a long shaft part, the center of gravity of the part will deviate, affecting the measurement result. Summary of the Utility Model

[0006] Aiming at the shortcomings of the prior art that the outer wall of long shaft parts cannot be measured, and due to the lack of a structure to keep the long shaft part always in a horizontal state, when measuring a long shaft part, the center of gravity of the part will deviate, affecting the measurement result, the utility model provides a long-axis type auxiliary tooling based on a hardness tester.

[0007] To solve the above technical problems, the utility model is solved by the following technical solutions:

[0008] A long-axis type auxiliary tooling based on a hardness tester includes an auxiliary support component. The auxiliary support component includes an auxiliary support platform with the same structure as the workbench of the measuring module. A connecting component is vertically connected to the side wall at the lower end of the auxiliary support platform. One end of the connecting component far away from the auxiliary support component is integrally provided with an adjusting sleeve that can be sleeved on the lead screw of the measuring module. A limiting component is provided on the adjusting sleeve to drive it to lock or unlock with the lead screw.

[0009] With the above solution, the auxiliary support platform can support one end of the long-axis part that tilts downward due to the offset of the center of gravity. The connecting component and the adjusting sleeve are arranged to connect the auxiliary support platform with the lead screw of the measuring module. After the adjusting sleeve is sleeved outside the measuring module, the position of the adjusting sleeve on the lead screw can be moved, so that the auxiliary support platform can be flush with the workbench of the measuring module. The limiting component can lock the movement of the adjusting sleeve after the height of the auxiliary support platform is adjusted by the adjusting sleeve, so as to realize the hardness measurement of the outer wall of the long-axis part.

[0010] Preferably, the limiting component includes a set screw, and a threaded hole is provided on the outer wall of the adjusting sleeve for the set screw to be screwed into and press against the outer wall of the lead screw of the measuring module.

[0011] With the above solution, after the adjusting sleeve moves on the lead screw, the set screw can be inserted into the threaded hole provided on the adjusting sleeve. After the set screw is screwed in, it will gradually approach the lead screw and press against the outer wall of the lead screw after contacting it, so as to limit the movement of the adjusting sleeve.

[0012] Preferably, an adjusting structure is provided between the auxiliary support platform and the connecting component to adjust the vertical lifting of the auxiliary support platform relative to the connecting component.

[0013] Preferably, the adjusting structure includes a screw rod rotatably inserted at one end into the bottom of the auxiliary support platform and a knob located at the end of the screw rod away from the auxiliary support platform. The connecting component is a flat connecting plate, and an internal threaded sleeve in threaded cooperation with the screw rod is integrally provided at one end of the connecting plate away from the adjusting sleeve.

[0014] With the above solution, the knob can drive the screw rod to rotate in the internal threaded sleeve. As the screw rod rotates, the screw rod will gradually move upward or downward. Since one end of the screw rod away from the knob is rotatably inserted into the bottom of the auxiliary support platform, when the screw rod rotates, the provided auxiliary support platform will also rotate together and move up and down under the drive of the screw rod, so as to further fine-tune the auxiliary support platform after the height of the adjusting sleeve is adjusted, so that the auxiliary support platform is flush with the workbench on the measuring module. At this time, the long-axis part can be placed on the auxiliary support platform and the workbench. If the connecting plate bends when the long-axis part is placed on the auxiliary support platform and the workbench, the height of the auxiliary support platform can be adjusted again through the knob, so as to reduce the trouble brought to the hardness measurement of the outer wall of the long-axis part due to the bending of the connecting plate.

[0015] Preferably, a positioning groove that fits the shaft part is provided at the upper end of the auxiliary support platform, and the positioning groove is an arc groove or a V-shaped groove.

[0016] With the above solution, the positioning groove provided on the auxiliary support platform can accommodate one end of the long-axis part that inclines downward due to the offset of the center of gravity. When the positioning groove is set as an arc groove or a V-shaped groove, it can fit with the outer circular wall of the long-axis part.

[0017] Since the present utility model adopts the above technical solution, it has remarkable technical effects: the auxiliary support platform provided can support one end of the long-axis part that inclines downward due to the offset of the center of gravity. The connecting component and the adjusting sleeve provided connect the auxiliary support platform with the lead screw of the measuring module. After the adjusting sleeve is sleeved outside the measuring module, the position of the adjusting sleeve on the lead screw can be adjusted, so that the auxiliary support platform can be flush with the workbench of the measuring module. The provided limiting component can lock the movement of the adjusting sleeve after the height of the auxiliary support platform is adjusted by the adjusting sleeve, thereby realizing the hardness measurement of the outer circular wall of the long-axis part.

[0026] The present utility model will be further described in detail below in conjunction with the drawings and embodiments.

[0027] Embodiment

[0028] An auxiliary tooling for long shaft parts based on a hardness tester, including an auxiliary support component. The auxiliary support component includes an auxiliary support table 4 with the same structure as the workbench 2 of the measurement module. In this embodiment, a V-shaped groove 3 is provided on the workbench 2. A positioning groove that fits the shaft part is provided at the upper end of the auxiliary support table 4. The positioning groove is an arc groove or a V-shaped groove 3. In this embodiment, it is a V-shaped groove 3. A connecting component is vertically connected to the side wall at the lower end of the auxiliary support table 4. One end of the connecting component away from the auxiliary support component is integrally provided with an adjusting sleeve 5 that can be sleeved on the lead screw 1 of the measurement module. A limiting component is provided on the adjusting sleeve 5 to drive it to lock or unlock with the lead screw 1.

[0029] The limiting component includes a set screw 7. A screw hole 6 is provided on the outer ring wall of the adjusting sleeve 5 for the set screw 7 to thread into and press against the outer wall of the lead screw 1 of the measurement module.

[0030] An adjusting structure for adjusting the vertical lifting of the auxiliary support table 4 relative to the connecting component is provided between the auxiliary support table 4 and the connecting component. The adjusting structure includes a screw rod 8 whose one end is rotatably inserted into the bottom of the auxiliary support table 4 and a knob 9 located at the end of the screw rod 8 away from the auxiliary support table 4. In this embodiment, a smooth rod section 801 is provided at the end of the screw rod 8 away from rotation. The smooth rod section 801 on the screw rod 8 is rotatably inserted into the bottom of the auxiliary support table 4. The connecting component is a flat connecting plate 10. An internal thread sleeve 11 that is threadedly matched with the screw rod 8 is integrally provided at one end of the connecting plate 10 away from the adjusting sleeve 5.

[0031] Specific measurement process: When the hardness tester needs to measure long-axis parts, the adjusting sleeve 5 can be first sleeved on the lead screw 1 in the measuring module, and then the position of the adjusting sleeve 5 is moved up and down to preliminarily connect the height of the auxiliary support table 4. After the movement of the adjusting sleeve 5 is completed, the set screw 7 can be screwed into the screw hole 6 on the adjusting sleeve 5 to press against the lead screw 1, so as to limit the movement of the adjusting sleeve 5. After that, rotate the knob 9 to drive the screw rod 8 to rotate and lift in the internal thread sleeve 11. Since the end of the screw rod 8 far from the knob 9 is rotatably inserted into the auxiliary support table 4, when the screw rod 8 rotates and lifts, the auxiliary support table 4 will also rotate and lift, so as to further adjust the position of the auxiliary support table 4. When the auxiliary support table 4 is further adjusted, a level can be used for measurement to make it flush with the workbench 2. If the V-shaped grooves 3 on the auxiliary support table 4 and the workbench 2 are not on the same straight line after the height adjustment of the auxiliary support table 4, at this time, the auxiliary support table 4 can be manually rotated to make the V-shaped grooves 3 on the auxiliary support table 4 and the workbench 2 on the same straight line. At this time, the part to be measured can be placed in the V-shaped grooves 3 on the auxiliary support table 4 and the workbench 2. If the connecting plate 10 bends under the pressure of the part to be measured after the part to be measured is placed on the auxiliary support table 4, the knob 9 can be rotated again to adjust the height of the auxiliary support table 4. Finally, a level is used to measure the auxiliary support table 4 and the workbench 2, so that the long-axis part placed in the V-shaped grooves 3 of the auxiliary support table 4 and the workbench 2 is in a horizontal state.

[0032] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
