[0044] Referring to Figure 1 The sleeve concentricity and runout detection mechanism of the embodiment comprises at least one ring groove 51 arranged on the outer circle of the sleeve 5.

[0045] The detection mechanism comprises a work platform and the following devices arranged on the work platform:

[0046] The positioning device 1 is used for positioning the sleeve 5;

[0048] The first detection device 3 comprises a first radial driving device 31 arranged on one radial side of the sleeve 5, a first detection table 32 connected with the driving end of the first radial driving device 31 and an adjusting device 33 used for adjusting the radial distance between the driving device and the sleeve 5, and the first detection table 32 can contact the ring groove 51;

[0050] In the embodiment, referring to Figure 2 , Figure 3As shown, the run-out size of the two circle grooves 51 and the run-out size of the top surface are detected based on the center hole of the sleeve 5. Therefore, two first detection devices 3 are needed. Through the above arrangement, the run-out of different circle grooves 51 on the outer circle of the sleeve 5 can be measured, and the detection efficiency is greatly improved. The detection mechanism can conveniently detect the run-out and concentricity tolerance of the sleeve 5.

[0051] In one embodiment, the positioning device 1 comprises a positioning table 11 and a positioning shaft 12 mounted on the positioning table 11, which can be inserted into the center hole of the sleeve 5, and the bottom end of the sleeve 5 is in contact with the positioning table 11. By using a servo rotary motor 21 and a rotary platform, the specified number of rotations can be rotated according to the detection requirements, and the detection of different parts or different numbers of circle grooves 51 of the workpiece can be conveniently realized. In addition, by replacing the positioning shaft 12 in the positioning device 1, the detection requirements of the sleeve 5 with different inner hole diameters can be met.

[0052] In one embodiment, referring to Figure 4 As shown, the rotating device 2 comprises a rotary motor 21 mounted on the workbench, a rotary table 22 connected to the driving end of the rotary motor 21, and the positioning table 11 is connected to the rotary table 22.

[0053] The first radial driving device 31 comprises a support seat 311, a sliding seat 312 slidingly connected to the support seat 311, a first sliding table cylinder 313 connected to the sliding seat 312, and a first sliding table 314 connected to the first sliding table cylinder 313. The adjusting device 33 comprises an adjusting seat 331, a screw rod 332 mounted on the adjusting seat 331 and threadedly connected to the sliding seat 312.

[0054] Specifically, referring to Figure 5 As shown, the first sliding table 314 is provided with a first detection seat 34, the first detection seat 34 is provided with a first supporting rod 35, and the first supporting rod 35 is provided with a first clamping seat 36 connected to the first detection surface 32 and adjusting the height position of the first detection surface 32.

[0055] Specifically, referring to Figure 6 As shown, the first sliding table cylinder 313 is provided with a first limiting rod 315 which can be adjusted in extension and retraction, and the first sliding table 314 can abut against the first limiting rod 315 when sliding in the retraction direction. A limiting seat 37 is arranged on one side of the extension direction of the first sliding table 314, and the limiting seat 37 is provided with a second limiting rod 38 which can abut against the first detection seat and can be adjusted in extension and retraction.

[0056] By setting the limiting rod or limiting seat 37, fine adjustment in the retracting or extending direction is realized. In this way, when different sizes or different types of sleeves 5 are replaced, only a small amount of fine adjustment is needed to quickly enter the detection state, improving versatility.

[0057] In one embodiment, referring to Figure 7 The second radial drive device 41 includes a second sliding table cylinder 411 and a second sliding table 412 connected to the second sliding table cylinder 411.

[0058] In one embodiment, the axial drive device 42 includes a column 421 connected to the second sliding table 412, a third sliding table cylinder 422 mounted on the column 421, and a third sliding table 423 connected to the third sliding table cylinder 422.

[0059] In one embodiment, the third sliding table 423 is mounted with a second detection seat 44, the second detection seat 44 is mounted with a second support rod 45, and the second support rod 45 is mounted with a second clamp seat 46 connected to the second detection table 43 and adjusting the horizontal position of the second detection table 43.

[0060] In one embodiment, the first detection table 32 and the second detection table 43 are Mal lever tables.

[0061] By using the first sliding table cylinder 313, the second sliding table cylinder 411, and the third sliding table cylinder 422 to drive the lever table, the table head can be automatically pressed against the surface or top surface of the sleeve 5 groove 51 to be detected, improving detection speed and measurement repeatability.

[0062] In addition, the mechanism can automatically transmit detection data to an industrial computer or host computer through RS232 or corresponding communication methods. After receiving the real-time maximum runout value, the host computer can automatically determine (OK / NOK) and store the detection data, facilitating subsequent data analysis, traceability, and management.

[0063] During operation, the operator first selects or inputs the product specifications or models (such as the diameters, lengths, and number of grooves 51 of different sleeves 5) that need to be detected on the industrial computer or host computer interface.

[0064] Manually install the sleeve 5 on the positioning device 1 (positioning shaft 12), ensuring that the bottom of the sleeve 5 tightly fits the positioning table 11, and the center hole is coaxially aligned with the positioning shaft 12. If the inner diameter of the sleeve 5 changes, the corresponding positioning shaft 12 can be replaced according to the requirements to adapt to different models of products.

[0065] After pressing the start button, the cylinders on the left and right (or multiple sides) runout detection devices start to work.

[0066] The first detection device 3 and the second detection device 4 move the lever table in the radial direction or the axial direction according to the set stroke, so that the table head is in contact with the groove 51 or the top plane 52. At this time, the real-time data of the runout is collected when the lever table rotates with the workpiece.

[0067] The rotary motor 21 drives the rotary platform to rotate the positioning table 11 and the sleeve 5 around the center axis. The sleeve 5 can be accurately rotated according to the number of revolutions or the angle set by the program, so as to ensure that the runout value can be collected comprehensively and completely during the measurement process.

[0068] The real-time data measured by the lever table is sent to the host computer through RS232 or other communication methods for data analysis. When the predetermined number of revolutions or the sampling times are reached, the rotary platform stops.

[0069] The host computer processes the collected continuous data to obtain the maximum value (or coaxial tolerance) of the runout value of the sleeve 5.

[0070] The detection result (OK or NOK) is determined according to the tolerance range set in advance. At the same time, the result and the original measurement data are stored in the database together for subsequent statistical analysis or quality traceability.

[0071] After the detection is completed, each cylinder and the slide table are automatically reset, and the lever table returns to the initial position, so as to detect the next product.

[0072] The operator manually removes the detected sleeve 5, and the detection process ends.

[0073] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the examples, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application. They should be included in the scope of the claims of the present application.
