Description

Technical Field

[0001] This utility model relates to the field of internal gear positioning technology, specifically a positioning device for internal gear machining. Background Technology

[0002] An internal gear is a special type of gear whose teeth are distributed on the inner surface of a hollow cylinder. Unlike common external gears, the tooth grooves of an internal gear are on the outside, while the tooth tips are on the inside. It has a central hole that can be used to connect with a shaft or other components to achieve the transmission of power or the conversion of motion.

[0003] A positioning device for internal gear machining, disclosed in CN 221111540 U, ​​has a plurality of clearance sliding holes corresponding one-to-one with the clamping rods through the top of the base, and the clearance sliding holes are arranged radially along the base. The top of the clamping rods extends through the clearance sliding holes to the top of the base, which can simultaneously adjust the position of each clamping rod, saving time and effort, while also providing high positioning stability and improving the machining accuracy of internal gears.

[0004] The positioning device for internal gear machining can clamp the internal gear with a clamping rod, but it does not have a mechanism for rotating the internal gear. When the machining device needs to process different positions of the internal gear, the operator needs to manually change the position of the internal gear, which is quite troublesome. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a positioning device for internal gear machining to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a positioning device for internal gear processing, comprising a support column, a fixed platform fixedly connected to the top of the support column, a rotating mechanism provided at the bottom of the fixed platform, a clamping mechanism provided at the top of the rotating mechanism, and an internal gear provided in the middle of the top of the rotating mechanism;

[0007] The rotating mechanism includes a fixed frame, which is fixedly connected to the bottom of a fixed platform. A drive motor is fixedly connected to the bottom of the fixed frame, and a worm gear is fixedly connected to the back end of the drive motor. A worm wheel meshes with the left side of the worm gear, and a linkage rod is fixedly connected to the inner side of the worm wheel. The bottom of the linkage rod is rotatably connected to the bottom of the fixed frame, and a rotating plate is fixedly connected to the top of the linkage rod. A support member is fixedly connected to the bottom of the rotating plate, and a protective plate is fixedly connected to the outer periphery of the bottom of the rotating plate. The top of the rotating plate and the bottom of the internal gear are in contact with each other.

[0008] Preferably, the inner side of the fixed platform has a circular hole corresponding to the position of the linkage rod, and the linkage rod is rotatably connected to the inner side of the circular hole. Through the circular hole, when the worm gear rotates, the linkage rod can drive the rotating plate to rotate.

[0009] Preferably, the inner side of the fixed platform is provided with a circular groove corresponding to the movement trajectory of the support member, and the support member is slidably connected inside the circular groove. The circular groove can limit the position of the support member, making the support member more stable during rotation. The support member can support the rotating disk, making the rotating disk more stable during rotation.

[0010] Preferably, the protective plate is disposed on the top of the fixed platform, and the bottom of the protective plate is in close contact with the top of the fixed platform. The protective plate can block the iron filings generated during processing, so that the iron filings do not fall into the circular groove opened on the inner side of the fixed platform.

[0011] Preferably, the clamping mechanism includes a dual-axis cylinder, which is fixedly connected to the top of the rotating plate. A second sliding plate is fixedly connected to the left side of the dual-axis cylinder, and a second V-shaped clamping plate is fixedly connected to the right side of the second sliding plate. A first sliding plate is fixedly connected to the right side of the dual-axis cylinder, and a first V-shaped clamping plate is fixedly connected to the left side of the first sliding plate.

[0012] Preferably, the top of the rotating plate is provided with a groove corresponding to the movement trajectory of the first sliding plate and the second sliding plate, and the first sliding plate and the second sliding plate are slidably connected inside the groove. The groove can limit the movement of the first sliding plate and the second sliding plate, making the first sliding plate and the second sliding plate more stable during movement.

[0013] Preferably, the inner side of the second V-shaped clamp is provided with a sliding groove corresponding to the movement trajectory of the first V-shaped clamp, and the first V-shaped clamp is slidably connected to the inside of the sliding groove. Through the sliding groove, the first V-shaped clamp can slide inside the second V-shaped clamp.

[0014] Compared with the prior art, this utility model provides a positioning device for internal gear machining, which has the following advantages:

[0015] The positioning device for internal gear machining uses a rotating mechanism that works in conjunction with a drive motor, worm gear, worm wheel, linkage rod, and rotating plate to allow the rotating plate to rotate 180 degrees left and right. This allows the rotating plate to drive the internal gear to rotate left and right. When drilling the internal gear, the operator does not need to manually change the position of the internal gear.

[0016] The positioning device for internal gear machining uses a clamping mechanism to place the internal gear on the top of the rotating plate. Through the cooperation of a double-shaft cylinder, a first sliding plate, and a second sliding plate, the first sliding plate can drive the first V-shaped clamping plate to move, and the second sliding plate can drive the second V-shaped clamping plate to move. This allows the first and second V-shaped clamping plates to clamp the internal gear, making the internal gear machining more stable. Attached Figure Description
