Description

Technical Field

[0001] The utility model relates to the technical field of motor processing, in particular to a motor end cover processing machine tool. Background Art

[0002] Motor end cover: It is the cover of the motor housing. It is generally divided into front cover and rear cover, which are used to fix and support the motor shaft. The material of the motor end cover is generally metal, including aluminum, aluminum casting, cold stamped steel, plastic, bakelite, etc. Generally, different materials are selected according to different motor types. For example, most automotive motors are cold stamped steel, and large motors are die-cast.

[0003] The quality of the motor end cover directly affects the quality of the motor. In order to ensure the installation accuracy, the end face, stopper and bearing mouth of the motor end cover need to be ground and polished. The current polishing method is to manually clamp the end cover on the grinder, and then use the motor to drive the grinding disc to grind the motor end cover. The end cover can only be replaced and polished manually one by one. There is a lack of special machine tools for automatic clamping, grinding and conveying, resulting in low efficiency in batch processing. Utility Model Content

[0004] In view of the above situation, in order to make up for the above existing defects, the utility model provides a motor end cover processing machine tool.

[0005] The utility model provides the following technical solutions: the utility model proposes a motor end cover processing machine tool, comprising a support frame, a grinding assembly is provided on the support frame, a feeding structure is provided on the side of the support frame, a conveying structure is provided on the side of the support frame away from the feeding structure, a grinding table is provided under the support frame, a fixing part is provided on the grinding table, the grinding table is arranged below the grinding assembly, a conveying assembly is provided on the support frame, and one end of the conveying assembly away from the support frame is arranged on the grinding assembly; the grinding assembly comprises a hydraulic press, a connecting plate is provided under the output end of the hydraulic press, a grinding motor is provided under the connecting plate, a grinding disc is provided at the output end of the grinding motor, when the end cover is sent to the grinding table, the hydraulic press is started, the output end of the hydraulic press moves downward, the hydraulic press moves downward with the grinding motor through the connecting plate during the movement, the grinding motor moves downward with the grinding disc, when the grinding disc contacts the end cover, the grinding motor is started, the grinding motor rotates with the grinding disc, and the end cover on the grinding table is polished.

[0006] Preferably, the fixing part includes a magnetic block, which is evenly arranged at the end of the connecting plate, and a slide groove is evenly arranged on the side of the grinding table. A magnetic slide bar is movably arranged in the slide groove. As the connecting plate moves downward, when the gravitational force between the magnetic block and the magnetic slide bar is greater than the gravity of the magnetic slide bar, the magnetic slide bar moves upward along the slide groove under the gravitational force, and the end cover on the grinding table is enclosed on the grinding table to prevent the end cover from being displaced during grinding and affecting the grinding effect.

[0007] Furthermore, the conveying assembly includes a fixed frame, which is symmetrically arranged on the side of the support frame away from the conveying structure, and a torsion spring is symmetrically arranged on the fixed frame, and a feeding plate is connected between the torsion springs, and a support rod is arranged under the support frame, and the support rod is arranged on one side of the hydraulic press, and a pulley is rotatably arranged under the support rod, and a pull wire is connected to the end of the feeding plate away from the grinding table, and the end of the pull wire is connected to the connecting plate, and the pull wire is arranged along the pulley, and a fixed rod is symmetrically arranged under the support frame, and the fixed rod is arranged between the support rod and the hydraulic press, and a locking member is provided on the fixed rod.

[0008] The locking member comprises a card ball, which is sleeved on the pull line, and the card ball is arranged below the pulley. A torsion spring three is arranged on the opposite side of the fixing rod, and a lever is connected between the torsion spring three. A card block is arranged on the upper end of the lever, and a through hole is arranged on the card block. A notch is arranged on the side of the card block away from the hydraulic press, and two torsion springs are evenly arranged in the through hole, and the two torsion springs are connected to the card plate, and the card block is evenly provided with limiting plates. The end of the limiting plate away from the card block is arranged above the card plate, and a protrusion is arranged on the connecting plate, and the protrusion is arranged on the side of the lever close to the hydraulic press, and the protrusion is a structure that is narrow on the top and wide on the bottom. The end cover is transported to the feeding plate by the feeding structure, and the end cover slides along the feeding plate to the grinding table. The connecting plate rotates by pulling the feeding plate through the pull line in the process of moving downward with the hydraulic press. At this time, the torsion spring one generates torque, and the feeding plate is tilted The state changes to a vertical state, and at the same time, the pull wire moves the card ball downward, so that the card ball passes over the card block and the card plate and moves to the bottom of the card block, and the card plate and the limiting plate are used to limit the card ball. When the grinding is completed, the hydraulic press is started again, and the hydraulic press moves the connecting plate upward, and the connecting plate moves the magnetic block upward. When the gravitational force between the magnetic block and the magnetic slide bar is less than the gravity of the magnetic slide bar, the magnetic slide bar falls along the slide groove, exposing the end cover on the grinding table, and continues to move the connecting plate upward.
