Description

Technical Field

[0001] This utility model relates to the field of commutator testing equipment, and in particular to a commutator mica groove depth laser online testing mechanism. Background Technology

[0002] As the core conductive commutation component of a motor (especially a DC motor or a series motor), the commutator has multiple mica slots evenly distributed along its circumference on its surface. Mica sheets are embedded in the mica slots to achieve insulation isolation between adjacent commutator segments. The depth accuracy of the mica slots directly determines the embedding stability of the mica sheets and the conductive contact area of ​​the commutator segments, which in turn affects the commutation reliability, spark suppression effect, and service life of the motor during operation.

[0003] In existing technologies, the mica groove depth of commutators is often tested by sampling, which results in a certain rate of product defect.

[0004] This application aims to provide a laser online detection mechanism for the depth of mica grooves in commutators. The mechanism uses a drive motor to drive a magnetic block to rotate, which in turn drives the rotor inside the commutator to rotate slowly, thereby facilitating the detection of all mica grooves by a laser detector.

[0039] Example 1:

[0040] A commutator mica groove depth laser online detection mechanism includes a worktable body 1, and a conveying mechanism 2 and a positioning mechanism 4 are provided at the upper end of the worktable body 1.

[0041] The conveying mechanism 2 includes a conveying motor 21, a conveyor belt 22 and a conveying roller 23. The surface of the conveyor belt 22 is provided with a clamping mechanism 3 for fixing the commutator.

[0042] The positioning mechanism 4 includes a mounting bracket 41, which is fixedly installed on the upper end of the workbench body 1. A drive mechanism 5 is provided on one bottom side of the mounting bracket 41.

[0043] The clamping mechanism 3 includes a clamping seat 31 and a clamping block 33. The clamping seat 31 is fixedly connected to the conveyor belt 22. Circular grooves 32 are symmetrically arranged on the inner walls of both sides of the clamping seat 31.

[0044] A pin 34 is fixedly connected to one side of the clamping block 33. A spring 35 is fixedly connected to the end of the pin 34 away from the clamping block 33. The spring 35 is fixedly installed inside the circular groove 32. The outer diameter of the pin 34 matches the inner diameter of the circular groove 32. The clamping block 33 is slidably connected to the mounting bracket 41 through the pin 34 and the spring 35.

[0045] An arc-shaped groove 36 is provided on the other side surface of the clamping block 33, and a rubber pad 37 is fixedly connected to the inner wall of the arc-shaped groove 36.

[0046] Support legs 11 are fixedly connected to the four corners of the bottom of the main body 1 of the workbench;

[0047] The conveyor motor 21 is fixedly installed at one end of the workbench body 1, the conveyor roller 23 is rotatably installed inside the workbench body 1, and the conveyor belt 22 is sleeved on the surface of the conveyor roller 23.

[0048] One end of the conveyor roller 23 is fixedly connected to a synchronous pulley 24, and a synchronous belt 25 is meshed with the surface of the synchronous pulley 24;

[0049] The output shaft of the conveyor roller 23 is fixedly connected to one of the synchronous pulleys 24, which is rotatably installed inside the housing of the worktable body 1.

[0050] Working principle and usage process: The commutator is clamped and fixed by the clamping mechanism 3 to facilitate subsequent detection of mica groove depth; during use, the commutator is placed between two sets of clamping blocks 33, and the commutator is clamped and fixed by the reaction force of the spring 35. The arc groove 36 of the clamping surface of the clamping block 33 matches the outer contour of the commutator, and the setting of the rubber pad 37 increases the clamping effect, making the commutator more stable.

[0051] The synchronous pulley 24 is driven to rotate by the transmission motor 21, which in turn drives the synchronous belt 25 to rotate. The synchronous belt 25 drives all the synchronous pulleys 24 to rotate, causing all the transmission rollers 23 to rotate synchronously, which in turn drives the transmission belt 22 to operate and transport the clamping mechanism 3.

[0052] Example 2:

[0053] The positioning mechanism 4 also includes a slider 44. The top and bottom of the mounting bracket 41 are provided with slide rails, and the slider 44 is slidably connected to the mounting bracket 41 through the slide rails.

[0054] A positioning motor 42 is fixedly connected to the top of the mounting bracket 41. A lead screw 43 is fixedly connected to the output shaft of the positioning motor 42. The lead screw 43 is rotatably installed inside the slide rail. The lead screw 43 passes through the slider 44 and is threadedly connected to the slider 44.

[0055] The bottom end of the slider 44 is fixedly connected to the first electric push rod 45, and the output end of the first electric push rod 45 is fixedly connected to the laser detector 6.

[0056] The improvement of this embodiment over the prior art is as follows: the positioning motor 42 drives the lead screw 43 to rotate, which in turn drives the slider 44 to move left and right within the range of the slide rail, so that the laser detector 6 can adjust its longitudinal position. The first electric push rod 45 drives the laser detector 6 to rise and fall, so that the height of the laser detector 6 can be changed. This allows the laser detector 6 to detect commutators of different sizes, increasing the practicality of the device.

[0057] Example 3:

[0058] The drive mechanism 5 includes a second electric push rod 51, which is fixedly installed at the bottom of the mounting bracket 41. A moving block 52 is fixedly connected to the output end of the second electric push rod 51. A groove 53 is provided on the right side surface of the moving block 52. An adjusting block 54 is slidably connected to the moving block 52 through the groove 53.

[0059] A positioning knob 55 is threadedly connected to one end of the upper part of the adjusting block 54, and a drive motor 56 is fixedly connected to the other end of the upper part of the adjusting block 54. A magnetic block 57 is fixedly connected to the output shaft of the drive motor 56.

[0060] The advantages of this embodiment over the prior art are as follows: by setting the drive mechanism 5 to drive the commutator to rotate, the laser detector 6 can detect all mica grooves on the surface of the commutator; by driving the moving block 52 to move towards the commutator by the second electric push rod 51, the magnetic block 57 is attracted and connected to the output shaft of the commutator, and the magnetic block 57 is driven to rotate by the drive motor 56, which drives the rotor inside the commutator to rotate slowly, thereby facilitating the laser detector 6 to detect all mica grooves. The magnetic block 57 is made of neodymium iron boron magnet.

[0061] By adjusting the position of the adjustment block 54, the drive motor 56 can be adjusted to its vertical height above the slide 53, and the position of the adjustment block 54 can be positioned by the positioning knob 55, so that the magnetic block 57 can be coaxially connected with the output shaft of commutators of different diameters, ensuring transmission stability.

[0062] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
