Description

Technical Field

[0001] This utility model relates to the field of motor cover drilling technology, specifically a device for drilling holes in the end cover of a micro motor. Background Technology

[0002] An end cover is a rear cover installed behind the housing of a motor or other machine, commonly known as an "end cover". The traditional end cover structure of a motor is a sheet metal stretching part, which has poor machinability. Later, it was improved to a stainless steel silica sol casting process, which greatly improved the machinability and reliability. When drilling holes in the end cover, a drilling device is required. Existing drilling devices are prone to producing burrs during the drilling process, and the burrs in the drilled holes must be polished and ground manually afterward, which reduces work efficiency.

[0003] The present invention aims to solve the technical problems existing in the prior art. To this end, a micro motor end cap punching device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a micro motor end cap punching device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A micro motor end cap punching device includes a worktable, a lifting device on one side of the worktable, and a transmission mechanism rotatably connected to the worktable. The lifting device cooperates with the transmission mechanism. The workbench is fixedly connected to a fixing device, which meshes with the transmission mechanism. A grinding device is provided on one side of the workbench, and the grinding device cooperates with the transmission mechanism.

[0006] As a further embodiment of this utility model: the lifting device includes a hydraulic cylinder, which is fixedly connected to the worktable. A lifting plate is fixedly connected to one end of the hydraulic cylinder. A drilling assembly is provided on one side of the lifting plate for drilling holes in the motor end cover. A slider is provided on one side of the lifting plate and cooperates with the transmission mechanism.

[0007] As a further embodiment of this utility model: the transmission mechanism includes a transmission shaft, which is rotatably connected to the worktable. The transmission shaft passes through the lifting plate. A guide groove is provided on the cylindrical surface of the transmission shaft. The slider is located in the guide groove and slides in contact with the transmission shaft. A transmission gear is fixedly connected to the cylindrical surface of the transmission shaft. The transmission gear meshes with a fixing device. A turntable is fixedly connected to the cylindrical surface of the transmission shaft. An extrusion block is provided on one side of the turntable. The extrusion block is inclined and cooperates with the grinding device.

[0008] As a further embodiment of this utility model: the fixing device includes a sleeve and a fixing rod. The sleeve is fixedly connected to the worktable. A driven gear is rotatably connected to the cylindrical surface of the sleeve. The driven gear meshes with the transmission gear. An inclined groove is provided on one side of the driven gear. The inclined groove is inclined. A limit block is fixedly connected to one end of the sleeve. The limit block has a limit groove. The fixing rod passes through the limit groove and slides in contact with the limit block. The other end of the fixing rod extends into the inclined groove and slides in contact with the driven gear.

[0009] As a further embodiment of this utility model: the grinding device includes a guide rod and a support block. The guide rod is fixedly connected to the worktable, passes through the support block and is slidably connected to the support block. The support block is in slidable contact with the turntable, and a grinding component is fixedly connected to one end of the support block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is in use, the hydraulic cylinder controls the lifting plate to rise and fall. The lifting plate drives the drilling assembly to descend for drilling. At the same time, the lifting plate drives the slider to move. Since the slider is located in the guide groove and slides in contact with the transmission shaft, the slider drives the transmission shaft to rotate through the guide groove during its descent. The transmission shaft drives the transmission gear to rotate. Since the transmission gear meshes with the driven gear, the transmission gear drives the driven gear to rotate. The driven gear drives the inclined groove to rotate. Since the fixed rod moves and is located in the inclined groove and slides in contact with the driven gear, when the driven gear rotates, it drives the fixed rod to move horizontally through the inclined groove. The device moves by clamping and fixing the motor end cover with the guide groove. At the same time, the drive shaft drives the turntable to rotate, and the turntable drives the extrusion block to rotate. The extrusion block tilts and supports the support block. The support block descends vertically along the guide rod. The support block drives the grinding assembly to descend. After opening, the lifting plate rises, the turntable resets, and the turntable supports the support block again through the extrusion block. The extrusion block squeezes the support block to rise, and the support block drives the grinding assembly into the hole drilled in the motor end cover to grind and remove burrs. This device facilitates automatic fixing of the motor end cover during drilling and automatic grinding and deburring of the drilled hole after drilling. Attached Figure Description
