Description

Technical Field

[0001] This utility model relates to the technical field of engine brush end cover processing equipment, specifically a milling fixture for engine brush end covers. Background Technology

[0002] A brush is a conductive component that forms an electrical connection by making sliding contact with a moving part. Brushes are used on commutators or slip rings as sliding contacts that introduce and discharge current. They have good electrical conductivity, thermal conductivity, and lubrication properties, and possess a certain mechanical strength and the ability to generate commutation sparks.

[0003] For example, CN213730538U discloses a "milling fixture for the end cover of a vehicle engine drive motor brush". This device includes a base plate, with side pillars fixedly installed on both the left and right sides of the top of the base plate. Positioning blocks are fixedly installed on the bottom wall of the inner cavity of the side pillars. After the entire fixture is mounted on the milling machine's worktable via the base plate, the end cover body is placed inside the positioning sleeve for initial positioning, facilitating subsequent clamping. Rotating the rotating block causes the threaded rod to rotate, at which point the movable sleeve moves downwards on the outer surface of the threaded rod, further moving the hook downwards and clamping it onto the end cover body, securing it. Then, rotating the threaded pressure rods on both sides causes the threaded pressure rods, along with protective blocks, to press against both sides of the end cover body for reinforcement. The protective blocks are made of soft rubber, preventing wear on the end cover body and achieving high practicality.

[0004] Although the above-mentioned fixtures have certain advantages in clamping end caps, they still have some drawbacks: when using the above-mentioned fixtures to clamp and process end caps, after completing one end of the end cap, when processing the other end, the end cap needs to be removed from the shell, then flipped over and clamped again. This method is quite troublesome. At the same time, manual assistance is required during the flipping process, which increases labor costs and affects processing efficiency. Utility Model Content

[0028] The working principle is as follows:

[0029] First, before use, bring the end cap housing 2 to be processed to the base 1 and wait for processing;

[0030] Second, in use, place the end cap housing 2 on the support plate 53, start the motor 32, the motor 32 drives the bidirectional screw 31 to rotate, the bidirectional screw 31 rotates and drives the movable block 34 to move, the movable block 34 moves and drives the fixed block 35 to move, the fixed block 35 moves and drives the fixed plate 36 to move, the fixed plate 36 moves and drives the round rod 37 to move, the round rod 37 moves and drives the clamping block 39 to move, the clamping block 39 clamps and fixes the end cap housing 2, and then the end cap housing 2 is processed by the milling device;

[0031] Third, after one end of the end cap housing 2 is processed, the end cap housing 2 needs to be flipped over and the other end processed. Start motor 3 42, motor 3 42 drives rotating rod 41 to rotate. When rotating rod 41 rotates, it drives gear 43 to rotate. When gear 43 rotates, it drives rack 44 to move. When rack 44 moves, it drives connecting block 45 to move, so that connecting block 45 moves out of the clamping block 39 and cancels the fixing effect on clamping block 39.

[0032] Fourth, when the rotating rod 41 rotates, it drives the round rod 47 to rotate through the pulley group 46. When the round rod 47 rotates, it drives the support block 55 to rotate, thus canceling the support effect of the support block 55 on the support plate 53.

[0033] Fifth, then start motor 2 38. Motor 2 38 drives round rod 1 37 to rotate. When round rod 1 37 rotates, it drives clamping block 39 to rotate. When clamping block 39 rotates, it drives end cover housing 2 to rotate. When end cover housing 2 rotates, it pushes support plate 53 to move downward. When support plate 53 moves, it moves along fixed rod 51 through sliding block 52. When fixed rod 51 moves, it compresses spring 54.

[0034] Sixth, after the end cap housing 2 has completed a 180-degree rotation, the spring 54 loses its force and pushes the sliding block 52 to move again. When the sliding block 52 moves, it drives the support plate 53 to move upward. The motor 3 42 is started, and the rotating rod 41 is controlled to rotate in the opposite direction, so that the connecting block 45 extends back into the clamping block 39 to restrict the position of the clamping block 39. When the rotating rod 41 rotates, it drives the round rod 2 47 to rotate through the pulley group 1 46, so that the support block 55 supports the support plate 53 again, and the end cap housing 2 continues to be processed. After the processing is completed, the clamping block 39 is removed from the end cap housing 2 by controlling the motor 1 32, and the processed end cap housing 2 can be taken out.
