Description

Technical Field

[0001] The utility model relates to the technical field of motor brush holders, in particular to a comprehensive testing device for motor brush holders. Background Art

[0002] The function of a brush holder is to apply pressure to the carbon brushes that slide in contact with the commutator or slip ring surface through a spring, enabling them to stably conduct current. A motor brush holder has a brush box that holds the carbon brushes securely in place. The box also uses spring pressure to hold the brushes in place, preventing vibration. Both the brush holder and the carbon brushes are crucial components. A suitable brush holder, combined with well-characterized carbon brushes, ensures the carbon brushes fully utilize their superior properties, providing stable electrical conduction and guaranteeing motor performance and life.

[0003] However, the above existing technologies for testing motor brush holders generally only perform spring force tests, and do not conduct tests after assembling the motor as a whole and then conduct comprehensive analysis to obtain test results. Such test results make it difficult to draw correct technical conclusions, and the test accuracy is greatly reduced. Some problems are difficult to detect at all, and there are certain limitations.

[0022] The motor brush holder comprehensive testing device includes a spring force detection mechanism 1 and a comprehensive detection mechanism 6. The comprehensive detection mechanism 6 is provided on one side of the spring force detection mechanism 1. A slide groove 3 is provided along both sides of the middle of the top of the combination of the spring detection mechanism 1 and the comprehensive detection mechanism 6. The centers of both sides of the slide groove 3 are respectively connected to the two sides of the screw rod 4. The surface of the screw rod 4 is sleeved with a sliding rod 7. The two ends of the sliding rod 7 pass through the limit rod 5. The two sides of the limit rod 5 are respectively connected to the two ends of the slide groove 3. The top of the sliding rod 7 is provided with a placement plate 8. A rotor commutator 9 is provided on the top of the placement plate 8, a vertical plate 11 is provided on the outer side of the back side of the comprehensive detection mechanism 6, a top plate 12 is provided on the top of the vertical plate 11, and electric telescopic rods 15 are provided at the four top corners of the top of the top plate 12. A fixed plate 14 is provided on the top of the four electric telescopic rods 15, and a test motor 13 is fixedly connected to the top center of the fixed plate 14. A first rotating shaft 18 is provided at the bottom output end of the test motor 13, a rotor 16 is provided at the bottom of the first rotating shaft 18, and a connecting rod 17 is provided at the bottom of the rotor 16.

[0023] Furthermore, a clamping block is provided at the bottom of the connecting rod 17 , and a clamping slot 10 is provided at the top center of the rotor commutator 9 , and the clamping block is clampedly connected to the clamping slot 10 .

[0024] Furthermore, a movable motor 2 is fixedly connected to the outer side of the spring force detection mechanism 1 , and an output end of the movable motor 2 is connected to one end of the screw rod 4 .

[0025] Specifically, the rotation of the moving motor 2 will cause the screw rod 4 to rotate, the rotation of the screw rod 4 will cause the sliding rod 7 to move, and the movement of the sliding rod 7 will drive the movement of the motor brush holder.

[0026] Furthermore, an inner cavity 19 is opened at the bottom center of the rotor 16, and a spring damper 20 is provided at the top center of the inner cavity 19. The telescopic end of the spring damper 20 is connected to the connecting rod 17. Specifically, when the rotor 16 moves downward, the connecting rod 17 will be subjected to a certain degree of pressure. The pressure will cause the connecting rod 17 to move toward the inner cavity 19, which will compress the spring damper 20, thereby playing a certain buffering role on the pressure.

[0027] Furthermore, a second rotating shaft 21 is provided at the bottom center of the rotor commutator 9, and a notch is opened at the top center of the placement plate 8, and the bottom of the notch is connected to the bottom of the second rotating shaft 21. Specifically, after the test motor 13 rotates and the bottom block of the connecting rod 17 is snap-connected to the slot 10, the rotation of the rotor 16 will mainly drive the rotation of the rotor commutator 9, and the rotation of the commutator 9 of the rotating shaft 1 is mainly driven by the second rotating shaft 21.

[0028] Working principle: The motor brush holder comprehensive testing device of the present invention first fixes the motor brush holder to the placement plate 8, wherein the placement plate 8 fixes the motor brush holder in a manner that is an existing mature technology, and its internal specific structure and working principle will not be described in detail here. Then, the spring force of the motor brush holder is detected by the spring force detection mechanism 1, and then the moving motor 2 is started to move the placement plate 8 from the spring force detection mechanism 1 end of the slide 3 to the other end, and then the electric telescopic rod 15 is started by the controller. The start of the electric telescopic rod 15 will shrink, thereby causing the fixed plate 14 to move downward, thereby causing the rotor 16 to move to the placement plate 3. At plate 8, when the block moves to slot 10, the rotor 16 and the motor brush holder are simply assembled into a motor assembly. The test power output line and the measurement signal line in the controller are connected to the carbon brushes on the carbon brush holder 12. Then, the test motor 13 is started. Driven by the test motor 13, the rotor 16 rotates at a variable speed, simulating the working condition of the motor. The computer data collector in the control cabinet measures the current, voltage, temperature, and speed of the rotor commutator through the test signal line. Specifically, this is a mature existing technology and will not be described in detail here. The working condition and performance indicators of the rotor commutator 9 and the carbon brushes are analyzed. This allows for a comprehensive test of the motor brush holder, not just a spring force test, and has certain practicality.

[0029] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
