[0029] The technical solutions of the present invention will be further described in detail below with reference to the drawings and embodiments.

[0030] The jitter debugging device provided by the embodiment of the present invention is applied to the jitter debugging of the slip ring of the current collector ring.Figure 1 The structural schematic diagram of a slip ring provided by an embodiment of the present invention is shown as follows Figure 1 As shown, a central column is provided at the bottom center of the slip ring 100 of the slip ring. A plurality of bolts are provided around the central column 101. Specifically, this jump debugging device is used for detecting a plurality of bolts at the bottom of the slip ring. Figure 2 、 Figure 3 The structural schematic diagram of a slip ring and a jump debugging device provided by an embodiment of the present invention is shown in combination with Figure 2 and Figure 3 As shown, this device specifically includes the following structures: an operating table 1, a turntable 2, a clamping mechanism 3, a pneumatic rotary actuator 4, a synchronous gear set 5, a rotary encoder 6, a micrometer 7, and an industrial control computer (not shown in the figure). The following will specifically introduce the structures of each part of the jump debugging device provided in this embodiment in combination with the attached Figures 1 to 3 drawings.

[0031] The operating table 1 is used to integrate and fix the turntable 2, the clamping mechanism 3, the pneumatic rotary actuator 4, the synchronous gear set 5, the rotary encoder 6, and the micrometer 7. Specifically, it can be an operating table 1 surface, and an opening groove is provided on the operating table 1 surface for placing the clamping mechanism 3.

[0032] The turntable 2, as shown in combination with Figure 4 is used to place the slip ring 100 to be detected. An installation groove is provided at the center of the turntable 2 for installing the clamping mechanism 3.

[0033] The clamping mechanism 3 can be understood as a chuck plate. As shown in combination with Figure 5 is fixed in the installation groove and includes a plurality of chucks 31. The chucks 31 are slidably arranged on the clamping mechanism 3 and are used for centering and fixing the slip ring 100. Specifically, the chucks 31 are driven by the pneumatic rotary actuator 4 and can move radially along the clamping mechanism 3 towards the center position, so as to clamp the central column 101 at the bottom of the slip ring. Thus, the fixing and centering of the slip ring 100 are realized. It can be understood that the installation groove of the turntable 2 can include a plurality of displacement grooves, and each chuck corresponds to a displacement groove for the displacement of the opening and closing of the chuck 31. During the test, the pneumatic rotary actuator 4 drives a plurality of chucks 31 to displace towards the center direction. After the test, the pneumatic rotary actuator 4 drives a plurality of chucks to displace away from the center direction. In a preferred embodiment, a plurality of grooves are provided on the contact surface between the chuck 31 and the central column 101 to increase the friction between the chuck 31 and the central column 101, and are used for clamping the central column 101 at the bottom of the slip ring to ensure the stability during the test. It should be noted that those skilled in the art can select and set the number of chucks 31 according to needs. In this embodiment, the number of chucks 31 is preferably 3, and the distances between the 3 chucks 31 are equal, so as to realize the clamping and centering of the central column 101 at the bottom of the slip ring.

[0034] The air pressure rotary device 4 can achieve rotary air intake and is used to provide air source power for the opening and closing of multiple jaws 31. It includes a fixed end and a rotary end. The rotary end of the air pressure rotary device 4 is connected to the output end at the bottom of the turntable 2. The turntable 2 drives the air pressure rotary device 4 to rotate synchronously through the rotary end. Specifically, a coupling sleeve is provided at the bottom of the clamping mechanism 3. The rotary end of the air pressure rotary device 4 is connected to the coupling sleeve through an internal thread to achieve synchronous rotation with the turntable 2. The fixed end of the air pressure rotary device 4 is fixed on the operating platform 1. Preferably, a stop baffle 12 is provided at the bottom of the operating platform 1. The fixed end of the air pressure rotary device 4 is fixed to the stop baffle 12 by bolts to ensure that the air pipe of the air pressure rotary device 4 is not twisted.

[0035] The synchronous gear set 5 includes a first synchronous gear 51 and a second synchronous gear 52. The two gears are of the same size and the same number of teeth. The central axis of the first synchronous gear 51 is connected to the rotary end of the air pressure rotary device 4. The second synchronous gear 52 meshes with the first synchronous gear 51. Thus, when the turntable 2 rotates, the turntable 2 drives the first synchronous gear 51 to rotate synchronously through the air pressure rotary device 4, and then drives the second synchronous gear 52 to rotate synchronously.

[0036] In a preferred embodiment, in order to fix the components, a fixing frame 11 is provided at the bottom of the operating platform 1 for fixing the clamping mechanism 3, the air pressure rotary device 4, and the synchronous gear set 5. Specifically, the fixed ends of the clamping mechanism 3, the air pressure rotary device 4, and the synchronous gear set 5 can all be fixed on the fixing frame 11 to ensure the stability of the overall structure of the device. Optionally, the above-mentioned stop baffle 12 can also be fixed on the fixing frame 11, thereby realizing the fixation of the air pressure rotary device 4 on the fixing frame 11.

[0037] The rotary encoder 6 is used to record the rotation angle data of the slip ring and is connected to the output end of the second synchronous gear 52, specifically to the central axis of the second synchronous gear 52. Thus, the synchronous rotation of the rotary encoder 6 and the slip ring is realized. When the rotary encoder 6 rotates, it automatically records the rotation angle data of the slip ring and uploads it to the industrial control computer.

[0038] The micrometer 7 is fixed on the operating platform 1. The micrometer 7 can be specifically fixed on the operating platform 1 through a magnetic dial and is used to measure and record the jump data of the slip ring. During the test, the contact of the micrometer 7 is in full contact with the slip ring, thereby recording the jump data of the slip ring and uploading it to the industrial control computer.

[0039] An industrial control computer, electrically connected to the receiving rotary encoder 6 and the micrometer 7, is used to receive the detection data of the receiving rotary encoder 6 and the micrometer 7, generate a jump value curve based on the slip ring rotation angle data and the slip ring jump value data, and analyze the jump value curve to obtain debugging information. Specifically, when the jump debugging device is working, the turntable 2 is divided into regions according to the position information of multiple bolts of the slip ring; the turntable 2 is rotated, and the pneumatic rotary actuator 4 is driven to rotate by the clamping mechanism 3, and then the synchronous gear set 5 is driven to rotate synchronously. The rotary encoder 6 synchronously collects the slip ring rotation angle data, and the micrometer 7 synchronously collects the slip ring jump data. Using the rotation angle data and the jump data as the horizontal and vertical coordinates respectively, a jump value curve is generated. It is judged whether the test is qualified according to whether the difference between the peak and valley of the jump value curve for one rotation is not greater than the preset value. If the difference between the peak and valley of the jump value curve is less than the preset value, the test is considered qualified. If the difference between the peak and valley of the jump value curve is not less than the preset value, the test is considered unqualified. When it is determined to be unqualified, the corresponding area information is obtained through the angle data at the position of the peak, and the position information of the bolt is obtained according to the area information, so as to obtain the bolt that needs to be adjusted. The debugging information is generated according to the bolt that needs to be adjusted, and the tester adjusts the bolt to be adjusted according to the debugging information. It should be noted that those skilled in the art can set the preset value as needed. In this example, the preset value is preferably 0.2 mm.

[0040] In a preferred embodiment, the jump debugging device further includes a proximity switch 8, which is installed on the operation table 1 and set at the circumferential position of the turntable 2. A stopper is provided at the bottom of the turntable 2. When the stopper rotates to the proximity switch 8, the proximity switch 8 is triggered to notify the jump debugging device to start recording data.

[0041] On the basis of understanding the structure of the jump debugging device for the slip ring 100 of the current collector ring provided in this embodiment, the working process will be described below with a specific embodiment. In this embodiment, there are 4 bolts at the bottom of the slip ring. Starting from the 0° position of the stopper at the bottom of the turntable 2, the turntable 2 is divided into 4 90° regions, and each region corresponds to 1 bolt.

[0042] Before the test starts, the current collector ring 100 is installed and fixed on the jump debugging device, and the position of the micrometer 7 is adjusted so that the contact head of the micrometer 7 is in full contact with the slip ring.

[0043] Press the experiment button and rotate the turntable 2 clockwise. When the stopper rotates to the proximity switch 8, the system is triggered to start recording the data collected by the device. Continue to rotate the turntable 2 clockwise. Thus, the pneumatic rotary actuator 4 is driven to rotate by the clamping mechanism 3, and then the synchronous gear set 5 is driven to rotate synchronously. The rotary encoder 6 synchronously collects the slip ring rotation angle data, and the micrometer 7 synchronously collects the slip ring jump data. Using the rotation angle data and the jump data as the horizontal and vertical coordinates respectively, a jump value curve is generated.

[0044] It is judged whether the test is qualified according to whether the difference between the peak and valley values of the runout value curve for one full rotation is not greater than the preset value (≤0.2 mm). In case of unqualified, the system will provide the position of the bolts that need to be adjusted, and determine which bolt to adjust based on the angle value of the position where the peak is located, and generate debugging information for manual adjustment. After adjustment, the test is carried out again for verification.

[0045] A runout debugging device for a current collector slip ring provided by an embodiment of the present invention, compared with the traditional method, realizes automatic centering of the workpiece through the form of an integrated claw chuck on the turntable, eliminates the systematic error brought by the traditional method that only relies on bolt fixation, reduces the original multiple runout debugging steps in different directions to one, greatly shortens the debugging time, and improves the operation efficiency. Moreover, compared with the traditional method of observing with a dial indicator and manually judging, this device can automatically judge whether the runout value detection is qualified and prompt the area where the bolts need to be adjusted through the generated runout value curve, reduces the influence of personnel experience value on the overhaul effect, and improves the quality of runout debugging.
