Description

Technical Field

[0001] The utility model relates to the technical field of motor brush sleeve riveting, in particular to a micro motor brush sleeve riveting device. Background Technique

[0002] The motor brush sleeve is used to sleeve on the carbon brush and is electrically connected to the coil winding. Since good electrical conductivity is required, it is generally made of copper. During the installation process of the motor brush sleeve, a riveting device is needed to fasten the motor brush sleeve to the carbon brush plate through the buckle feet at its bottom.

[0003] Please refer to a motor brush sleeve riveting device with the publication number of CN209948918U, which includes a base and a lower support plate. A central positioning block, an inner support block and a first driving mechanism are arranged in the middle of the lower support plate. The shape of the inner support block is the same as the inner hole shape of the motor brush sleeve. An upper die pressing block and a second driving mechanism are also arranged above the lower support plate. A die pressing groove consistent with the outer contour of the motor brush sleeve is arranged at the lower part of the upper die pressing block; the carbon brush plate with the motor brush sleeve is placed on the lower support plate, and the central through hole of the carbon brush plate is sleeved on the central positioning block. The first driving mechanism drives the inner support block to move horizontally and then embed into the inside of the motor brush sleeve. The second driving mechanism drives the upper die pressing block to descend, and the die pressing groove wraps the outside of the motor brush sleeve, so as to realize the riveting of the motor brush sleeve. Since the inner support block with the same shape as the inner hole of the motor brush sleeve is embedded inside the motor brush sleeve and the die pressing groove consistent with the outer contour of the motor brush sleeve is sleeved outside, it ensures that the motor brush sleeve will not deform during the riveting process.

[0004] In the above patent, the motor brush sleeve is limited and fixed through the cooperation of the die pressing groove, the support block and the limiting block. However, when the carbon brush plate is placed on the support plate, the carbon brush plate blocks the support block and the limiting block, making the support block unable to extend into the inside of the motor brush sleeve, thus reducing the effect of clamping and limiting the motor brush sleeve, and further affecting the riveting quality of the buckle feet of the motor brush sleeve and the carbon brush plate. The present application proposes another technical solution to solve this technical problem. Content of the Utility Model

[0031] Specifically, when using this micro motor brush sleeve riveting equipment, start the four micro electric push rods 5 to drive the connecting plate 6 to move away from the pressing block 2. The slider 10 slides on the sliding rod 4, driving the mounting rod 9 to move synchronously, thereby moving the mounting rod 9 out of the interior of the mounting frame 3. Subsequently, the electric brush sleeve is initially limited and clamped in the clamping groove of the pressing block 2. Then, start the micro electric push rod 5 again to drive the connecting plate 6 to move in the direction closer to the pressing block 2, so that the screw rod 7 penetrates through and is inserted into the pressing block 2. Then, rotate the rotating clamping block 8 to limit and fix the motor brush sleeve through the rotating clamping block 8, reduce the looseness of the motor brush sleeve during limiting, and facilitate the improvement of the riveting effect of the device.

[0032] Embodiment 2: Please refer to Figure 1 , on the basis of Embodiment 1, a limit positioning component is further installed on the base 1.

[0037] It should be noted that the micro motor brush sleeve riveting equipment is convenient for limiting the brush plate by installing a limited positioning component, so that the buckle foot can be accurately riveted with the brush plate, thereby improving the accuracy of riveting and improving the quality of riveting.

[0038] Specifically, when the micro motor brush sleeve riveting equipment is used, the brush plate is limited on the placement plate 13 by the positioning block 19, and then the two first electric telescopic rods 15 are started to drive the two clamps 16 to move in opposite directions, thereby limiting the two ends of the brush plate, and then the cylinder 18 is started to drive the pressing block 2 to move downward, so that the motor brush sleeve moves downward synchronously, and when the buckle foot of the motor brush sleeve moves to the top of the buckle foot top block 12, the pressing block 2 continues to be pressed downward, and the second electric telescopic rod is started to move at the same time, so that the placement plate 13 moves downward synchronously, so that the buckle foot of the motor brush sleeve is supported by the buckle foot top block 12 and buckled on the bottom of the brush plate, thereby realizing the riveting of the motor brush sleeve.

[0039] The working principle of the above embodiment is:

[0040] (1) When the micro motor brush sleeve riveting device is used, the four micro electric push rods 5 are started to drive the connecting plate 6 to move away from the pressing block 2, and the slider 10 slides on the slide rod 4 to drive the installation rod 9 to move synchronously, thereby moving the installation rod 9 out of the installation frame 3, and then the brush sleeve is initially limited and clamped in the clamping groove of the pressing block 2, and then the micro electric push rod 5 is started again to drive the connecting plate 6 to move in a direction close to the pressing block 2, so that the screw 7 passes through the interior and is plugged into the pressing block 2, and then the rotating clamp 8 is rotated to limit and fix the motor brush sleeve by rotating the clamp 8, thereby reducing the looseness of the motor brush sleeve when limiting, and facilitating the riveting effect of the device.
