Description

Technical Field

[0001] This utility model relates to the field of diamond roller testing technology, and in particular to a diamond roller surface runout testing device. Background Technology

[0002] In the production process of diamond rollers, surface runout detection is required to ensure machining accuracy.

[0003] Surface runout of diamond rollers can be detected using a dial indicator. The measuring head at the bottom of the dial indicator contacts the outer circumference of the rotating diamond roller to detect surface runout. However, the measuring head of the dial indicator is typically a needle-tip structure, which can easily become stuck in the gaps between the diamond particles on the outer circumference of the diamond roller during testing, affecting the accuracy of the results.

[0004] Furthermore, diamond rollers of different specifications have different diameters of their center holes, which can lead to significant errors during clamping. This results in surface runout during rotation due to clamping issues, further affecting the accuracy of the test results and necessitating improvements. Utility Model Content

[0005] The purpose of this invention is to provide a diamond roller surface runout detection device that is adaptable to diamond rollers of different specifications and improves the accuracy of the detection results.

[0006] To achieve this objective, the present invention adopts the following technical solution:

The bearing housing is mounted on the bracket, and the rotating shaft is horizontally disposed within the bearing housing. A disc is disposed at the front end of the rotating shaft, and a stud concentric with the rotating shaft is disposed on the front side of the disc. The first outer conical sleeve is concentrically disposed on the stud, and the diamond roller is disposed on the stud and located in front of the first outer conical sleeve. The outer conical surface of the first outer conical sleeve contacts the rear end of the central hole of the diamond roller. The second outer conical sleeve is concentrically disposed on the stud and located in front of the diamond roller. The outer conical surface of the second outer conical sleeve contacts the front end of the central hole of the diamond roller. The dial indicator is suspended above the diamond roller, and the steel balls are disposed at the bottom of the measuring rod of the dial indicator and roll in contact with the surface of the diamond roller.

[0008] The stud is provided with a nut located in front of the second outer cone sleeve.

[0009] The dial indicator has a threaded sleeve at the bottom of its measuring rod. The inner hole of the threaded sleeve has a spherical groove corresponding to the steel ball. The steel ball is placed in the spherical groove, and the bottom of the steel ball protrudes outward from the bottom surface of the threaded sleeve.

[0010] The rear end of the rotating shaft is provided with a handle.

[0011] The bracket has a vertical column located on one side of the bearing seat. A first guide sleeve extends vertically on the column. A second guide sleeve extends horizontally on the first guide sleeve. A cantilever extends above the diamond roller in the second guide sleeve. The dial indicator is located at the front end of the cantilever.

[0012] The first guide sleeve is provided with a first screw pointing to the column, and the second guide sleeve is provided with a second screw pointing to the cantilever.

[0013] The first and second outer conical sleeves are provided with through holes corresponding to the studs.

[0014] The beneficial effects of this utility model are as follows: A diamond roller surface runout detection device, which specifically adopts a first outer conical sleeve and a second outer conical sleeve, can achieve clamping and self-centering of both ends of the diamond roller's central hole, reduce the surface runout problem caused by clamping errors, improve the adaptability to the central hole diameter of diamond rollers of different specifications, and utilize the rolling contact between steel balls and the diamond roller surface to avoid the problem of getting stuck in the gaps between diamond particles, which is conducive to improving the accuracy of the detection results.

[0015] Figure 1 This is a schematic diagram of the structure of this utility model;

[0016] Figure 2 yes Figure 1 A magnified view of part A in the middle. Detailed Implementation

[0017] The following is combined Figures 1 to 2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0018] like Figure 1 The diamond roller surface runout detection device shown is used for surface runout detection of diamond roller 6. It includes: bracket 1, bearing seat 2, rotating shaft 3, first outer cone sleeve 11, second outer cone sleeve 12, dial indicator 8 and steel ball 20. The bearing seat 2 is mounted on the bracket 1 and can be fixed with screws, so the structure is stable.

[0019] The rotating shaft 3 is horizontally installed in the bearing housing 2. A disc 14 is provided at the front end of the rotating shaft 3. A stud 10 concentric with the rotating shaft 3 is provided on the front side of the disc 14. The rotating shaft 3, the disc 14 and the stud 10 are made of integrated steel structure and are integrally machined to ensure concentricity. A handle 4 is provided at the rear end of the rotating shaft 3 for convenient manual rotation operation.

[0020] The first outer cone sleeve 11 is concentrically mounted on the stud 10, such as Figure 1 As shown, the first outer conical sleeve 11 is positioned against the disc 14 for limiting. The diamond roller 6 is mounted on the stud 10 and located in front of the first outer conical sleeve 11. The diameter of the central hole 22 of the diamond roller 6 is much larger than the outer diameter of the stud 10 to avoid contact between the central hole 22 and the stud 10.

[0021] The second outer conical sleeve 12 is concentrically disposed on the stud 10 and located in front of the diamond roller 6. The first outer conical sleeve 11 and the second outer conical sleeve 12 are provided with through holes corresponding to the stud 10 to ensure the concentricity of the stud 10, the first outer conical sleeve 11 and the second outer conical sleeve 12.

[0022] The outer conical surface of the first outer conical sleeve 11 contacts the rear end of the center hole 22 of the diamond roller 6, and the outer conical surface of the second outer conical sleeve 12 contacts the front end of the center hole 22 of the diamond roller 6. A nut 13 located in front of the second outer conical sleeve 12 is provided on the stud 10 to lock the second outer conical sleeve 12, thereby achieving self-centering of the diamond roller 6 and ensuring the concentricity of the diamond roller 6 and the rotating shaft 3. This reduces surface runout caused by clamping errors and improves the adaptability to the diameter of the center hole 22 of diamond rollers of different specifications.

[0023] The dial indicator 8 is suspended above the diamond roller 6, and the steel ball 20 is located at the bottom of the measuring rod 9 of the dial indicator and rolls in contact with the surface of the diamond roller. Figure 2 As shown, the bottom of the measuring rod 9 of the dial indicator 8 is provided with a screw sleeve 19, which is connected to the measuring rod 9 by a thread, making disassembly and assembly relatively convenient.

[0024] The inner bottom of the threaded sleeve 19 is provided with a spherical groove 21 corresponding to the steel ball 20. The steel ball 20 is disposed in the spherical groove 21, and the bottom of the steel ball 20 protrudes outward from the bottom surface of the threaded sleeve 19, ensuring rolling contact between the steel ball 20 and the surface of the diamond roller 6. Lubricating oil is applied to the spherical groove 21 to reduce friction and resistance during the rotation of the steel ball 20. The large diameter of the steel ball 20 can avoid the problem of getting stuck between diamond particles, which helps to improve the accuracy of the test results.

[0025] To facilitate the adjustment of the dial indicator 8, a vertical column 18 is installed on the bracket 1, located on one side of the bearing seat 2. A vertically extending first guide sleeve 16 is installed on the column 18. Figure 1 As shown, the first guide sleeve 16 is provided with a first screw 17 pointing to the column 18, which facilitates the height adjustment and fixation of the first guide sleeve 16 to accommodate diamond rollers 6 with different outer diameters.

[0026] The first guide sleeve 16 is provided with a horizontally extending second guide sleeve 5. The first guide sleeve 16 and the second guide sleeve 5 can be welded and fixed, with good synchronization. The second guide sleeve 5 is provided with a cantilever 7 extending above the diamond roller 6. The second guide sleeve 5 is provided with a second screw 15 pointing to the cantilever 7, which facilitates the lateral adjustment and fixing of the cantilever 7.

[0027] like Figure 1 As shown, the dial indicator 8 is mounted at the front end of the cantilever 7 and can be fixed with screws for easy replacement. By adjusting the lateral movement and height of the cantilever 7, the steel ball 20 rolls into contact with the surface of the diamond roller 6. The shaft 3 rotates at a low speed, driving the diamond roller 6 to rotate. Based on the changes in the pointer of the dial indicator 8, the surface runout of the diamond roller 6 can be detected.

[0028] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
