Description

Technical Field

[0001] The utility model relates to the technical field of concentricity detection, in particular to a concentricity detector for a mechanical movement wheel disc. Background Technique

[0002] A concentricity detector is a precision instrument used to measure the concentricity of an object (i.e., the deviation between the geometric center and the physical center). The concentricity detector for a mechanical movement wheel disc is an important tool for measuring the coaxiality of mechanical parts, especially in high-precision mechanical manufacturing, its application is particularly important.

[0003] However, when using the traditional concentricity detector for a mechanical movement wheel disc, it is necessary to find points and limit positions from multiple angles according to the position of the wheel disc. The detection process requires multiple adjustments, which takes a long time and has low detection efficiency. Content of the Utility Model

[0004] The utility model discloses a concentricity detector for a mechanical movement wheel disc, aiming to solve the technical problems that when using the traditional concentricity detector for a mechanical movement wheel disc, it is necessary to find points and limit positions from multiple angles according to the position of the wheel disc, the detection process requires multiple adjustments, which takes a long time and has low detection efficiency.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme:

[0006] A concentricity detector for a mechanical movement wheel disc, including a detection table, a wheel disc body, and a mounting seat, a connecting seat, and a connecting block provided on the detection table, further including:

[0007] An adjusting mechanism: The adjusting mechanism is provided on the connecting block;

[0008] A linkage mechanism is provided on the connecting seat. A threaded column is provided on the linkage mechanism. A connecting collar is provided on the circumferential outer wall of the threaded column. A limiting rod is provided on one outer wall of the connecting seat. The connecting collar slides on the circumferential outer wall of the limiting rod. A thimble is provided on the inner wall of the connecting collar. A rotating shaft is provided on the inner wall of the mounting seat. A sleeve is provided on one outer wall of the rotating shaft. The wheel disc body is located between the sleeve and the thimble. A dial indicator is provided on the adjusting mechanism, and a detection head is connected to the bottom end of the dial indicator.

[0009] In this solution, the linkage mechanism drives the threaded column to rotate, causing the connecting collar to be pushed forward under the limitation of the limiting rod, so that the tip of the contactor presses against the contact position between the wheel disc body and the sleeve. Under the adjustment of the adjustment mechanism, the dial indicator aligns the detection head with the wheel disc body and zeros the dial indicator. Then, under the rotation of the rotating shaft, the concentricity of the inner side of the wheel disc body is detected by the tip of the contactor, and the concentricity of the outer side of the wheel disc body is detected by the detection head of the dial indicator. The alignment work can be carried out simultaneously at the linear positions on both sides of the wheel disc body. The static adjustment of the concentricity of the movement wheel disc body by how many microns can be achieved through the dial indicator. The concentricity of the wheel disc body is detected, and the rotation of the wheel disc body is stable, and the use effect is better.

[0010] In a preferred solution, the adjustment mechanism includes a limiting screw and a connecting rod provided on the inner wall of the connecting block. A connecting frame is connected to the circumferential outer wall of the connecting rod by a hinge. Two limiting holes are opened on one outer wall of the connecting frame. A dial indicator frame is slidably connected to the connecting frame. A connecting long hole is opened on one outer wall of the dial indicator frame.

A threaded rod is provided on the inner wall of the adapting block. A sleeve rod is provided on the circumferential outer wall of the threaded rod.

[0011] Adopting the above technical solution, the connecting frame can move back and forth on the connecting rod. According to the position of the wheel disc body, the position of the dial indicator frame is adjusted. When the limiting screw is limited in the connecting long hole and one of the limiting holes, the position of the dial indicator frame is fixed. During the process of moving the connecting frame back and forth, the sleeve rod moves on the threaded rod at the same time, so as to adjust the dial indicator frame to be closer to or farther away from the wheel disc body. More flexibly, the detection head is aligned with the wheel disc body, the adjustment is convenient, it is easier to align the position, and the time consumption is short.

[0012] As can be seen from the above, a concentricity detector for a mechanical movement wheel disc includes a detection table, a wheel disc body, a mounting seat, a connecting seat and a connecting block provided on the detection table, and further includes:

[0013] Adjustment mechanism: The adjustment mechanism is provided on the connecting block;

Detailed Description of the Embodiment

[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application required to be protected, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0020] A concentricity detector for a mechanical movement wheel disc disclosed by the present utility model is mainly applied to the scenario where when using a traditional concentricity detector for a mechanical movement wheel disc, it is necessary to find points and limit positions from multiple angles according to the position of the wheel disc. The detection process requires multiple adjustments, which takes a long time and has low detection efficiency.

[0021] Referring to Figure 1 and Figure 2 , a concentricity detector for a mechanical movement wheel disc includes a detection table 1, a wheel disc body 5, and a mounting seat 2, a connecting seat 3, and a connecting block 4 provided on the detection table 1, and further includes:

[0022] Adjusting mechanism: The adjusting mechanism is provided on the connecting block 4;

[0023] A linkage mechanism is provided on the connecting seat 3. A threaded column 15 is provided on the linkage mechanism. A connecting collar 16 is screwed on the circumferential outer wall of the threaded column 15. A limiting rod 10 is fixedly connected to the outer wall of one side of the connecting seat 3. The connecting collar 16 slides on the circumferential outer wall of the limiting rod 10. A thimble 11 is provided on the inner wall of the connecting collar 16. A rotating shaft 9 is connected to the inner wall of the mounting seat 2 through a bearing. A sleeve is provided on the outer wall of one side of the rotating shaft 9. The wheel disc body 5 is located between the sleeve and the thimble 11. A dial indicator 6 is provided on the adjusting mechanism. A detection head 12 is fixedly connected to the bottom end of the dial indicator 6.

[0024] In the specific working process, the linkage mechanism drives the threaded column 15 to rotate, so that the connecting collar 16 is pushed forward under the limitation of the limiting rod 10, so that the thimble 11 presses against the contact position between the wheel disc body 5 and the sleeve. Under the adjustment of the adjusting mechanism, the dial indicator 6 aligns the detection head 12 with the wheel disc body 5, and the dial indicator 6 is zeroed. Then, under the rotation of the rotating shaft 9, the thimble 11 detects the concentricity of the inner side of the wheel disc body 5, and the detection head 12 of the dial indicator 6 detects the concentricity of the outer side of the wheel disc body 5.

[0025] Among them, both the detection head 12 and the thimble 11 are used in cooperation with the wheel disc body 5. In this way, both the detection head 12 and the thimble 11 are aligned with the wheel disc body 5, and the concentricity of the outer circle and the inner circle of the wheel disc body 5 can be detected simultaneously. During the rotation of the rotating shaft 9, the concentricity of different positions of the wheel disc body 5 is detected, and the recorded results are more comprehensive.

[0026] Referring to Figure 1 and Figure 2 , in a preferred embodiment, the linkage mechanism includes a rotating wheel 7 provided on the outer wall of one side of the connecting seat 3. A driving gear 13 is provided on the circumferential outer wall of the rotating wheel 7 passing through the connecting seat 3. A connecting shaft 8 is provided on the outer wall of one side of the connecting seat 3 close to the rotating wheel 7. A driven gear 14 is provided on the circumferential outer wall of the connecting shaft 8 passing through the connecting seat 3. The driven gear 14 is connected to the threaded column 15, and the driving gear 13 is meshed with the driven gear 14.

[0027] Specifically, as the rotating wheel 7 rotates, it drives the driving gear 13 to rotate. Since the driving gear 13 meshes with the driven gear 14, the driven gear 14 is driven to rotate, causing the threaded post 15 connected to the driven gear 14 to rotate, so that the thimble 11 clamps the wheel body 5. The linkage effect of the whole process is good.

[0028] Refer to Figure 1 and Figure 3 As shown in and, in a preferred embodiment, the adjusting mechanism includes a limit screw 17 and a connecting rod 22 provided on the inner wall of the connecting block 4. A connecting frame 19 is hinged to the circumferential outer wall of the connecting rod 22. Two limit holes 20 are formed on one outer wall of the connecting frame 19. A dial gauge holder 18 is slidably connected to the connecting frame 19. A connecting long hole is formed on one outer wall of the dial gauge holder 18. The limit screw 17 is respectively used in cooperation with the connecting long hole and the two limit holes 20. An adapter block 21 is provided on one inner wall of the mounting seat 2. A threaded rod 23 is provided on the inner wall of the adapter block 21. A sleeve rod is provided on the circumferential outer wall of the threaded rod 23. The connecting frame 19 is sleeved on the circumferential outer wall of the sleeve rod near the bottom end.

[0029] Specifically, the connecting frame 19 can move back and forth on the connecting rod 22. According to the position of the wheel body 5, the position of the dial gauge holder 18 is adjusted. When the limit screw 17 is limited in the connecting long hole and one of the limit holes 20, the position of the dial gauge holder 18 is fixed. During the process of moving the connecting frame 19 back and forth, the sleeve rod moves on the threaded rod 23 at the same time. Thus, while the connecting frame 19 is tilted back and forth, the dial gauge holder 18 can be adjusted to be closer to or farther from the wheel body 5.

[0030] Among them, the lever dial gauge 6 is located on the inner wall of the dial gauge holder 18. The connecting frame 19 is used in cooperation with the lever dial gauge 6. In this way, by adjusting the position of the dial gauge holder 18, the position of the lever dial gauge 6 is moved, so that the detection head 12 on the lever dial gauge 6 is aligned with the wheel body 5, and then the concentricity detection is carried out.

[0031] It should be noted that the lever dial gauge 6 can use a lever micrometer or a lever dial indicator. Select the corresponding lever dial gauge 6 according to the actual use situation, and then carry out the concentricity detection.

[0032] Working principle: When in use, according to the position of the wheel disc body 5, rotate the rotating wheel 7 to make the driving gear 13 rotate. Since the driving gear 13 meshes with the driven gear 14, the driven gear 14 is driven to rotate, so that the threaded column 15 connected to the driven gear 14 rotates, and the connecting collar 16 is pushed forward under the limitation of the limiting rod 10, so that the thimble 11 presses against the contact position between the wheel disc body 5 and the sleeve. Then, adjust the position of the dial indicator 6. While moving the connecting frame 19 back and forth, the sleeve rod moves on the threaded rod 23, so as to adjust the detection head 12 of the dial indicator 6 on the meter frame 18 to align with the wheel disc body 5. The dial indicator 6 is zeroed. Then, under the rotation of the rotating shaft 9, the thimble 11 detects the concentricity inside the wheel disc body 5, and the detection head 12 of the dial indicator 6 detects the concentricity outside the wheel disc body 5. After the detection, record the results.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of part of the structure, device, and method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept shall be covered by the protection scope of the present invention.
