Description

Technical Field

[0001] This utility model relates to the field of speed reducer forging technology, and in particular to a speed reducer housing forging fixture. Background Technology

[0002] A speed reducer is an independent component consisting of gear drives, worm gear drives, or gear and worm gear drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between a prime mover and a driven machine, matching speeds and transmitting torque between the prime mover and the driven machine or actuator. It is widely used in modern machinery. A speed reducer is a relatively precise machine used to reduce speed and increase torque. There are many types and models of speed reducers, each with different applications. According to transmission type, they can be divided into gear reducers, worm gear reducers, and planetary gear reducers; according to the number of transmission stages, they can be divided into single-stage and multi-stage reducers.

[0003] Regardless of the type of speed reducer, the manufacturing process requires forging the speed reducer housing, followed by grinding, polishing, painting, and drilling. During the forging process, the speed reducer housing needs to be clamped to ensure stability. Most existing speed reducer housing forging fixtures use bench vises for clamping, which, while providing strong clamping stability, can easily damage the speed reducer housing. Furthermore, different types of bench vises need to be used to clamp speed reducer housings of different sizes and shapes, resulting in poor convenience. Therefore, a speed reducer housing forging fixture needs to be designed to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a forging fixture for a speed reducer housing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A forging fixture for a speed reducer housing includes a fixed frame. A motor is mounted at the center of the bottom of the fixed frame. The motor's shaft is fixedly connected to the center of the bottom of a rotating disk. The rotating disk is rotatably connected to the inner upper part of the fixed frame. Movable clamping units are provided at the front, back, left, and right sides of the upper end of the rotating disk. A fixed disk is mounted on the upper part of the rotating disk. Fixed plates are fixedly connected to the four corners of the upper end of the fixed frame. Pushing clamping units are provided on the inner sides of the fixed plates. The fixed frame is used to fix the motor, the fixed disk, and the fixed plates, and also serves to rotatably connect the rotating disk. The motor drives the rotating disk. The rotating disk drives the movable clamping units to move back and forth. The fixed disk guides the movable clamping units. The fixed plates fix the pushing clamping units. The movable clamping units clamp the speed reducer housing at the front, back, left, and right sides. The pushing clamping units clamp the four corners of the speed reducer housing.

[0007] The above technical solution uses a motor to drive the rotating disk to rotate, which in turn causes the arc-shaped rotating groove to move the moving clamping unit. The moving position of the moving clamping unit is then limited by a fixed disk. The clamping unit follows the rotating disk and moves back and forth, clamping the reducer housing in all directions. This method is easy to control and can stably clamp reducer housings of different sizes and shapes. It also has high clamping stability, preventing damage to the reducer housing due to excessive clamping force, while preventing loose clamping due to insufficient clamping force.

[0008] Furthermore, a rotating groove is provided in the middle of the upper end of the fixing frame, a mounting hole is provided in the middle of the rotating groove, and a mounting groove is provided on the outer side of the upper end of the fixing frame.

[0009] With the above technical solution, the rotating disk rotates inside the rotating groove, the mounting groove facilitates the installation of the fixed disk, and the mounting hole facilitates the passage of the motor shaft to be fixed to the rotating disk.

[0010] Furthermore, the rotating disk has several arc-shaped rotating grooves equidistantly arranged in the middle.

[0011] Through the above technical solution, during the rotation of the arc-shaped rotating groove, the moving clamping unit is driven to move its position back and forth.

[0012] Furthermore, the movable clamping unit includes a connecting column, and a fixed seat is provided at the upper end of each connecting column. A connecting seat is fixedly connected to the upper end of each fixed seat, and a clamping seat is fixedly connected to the inner side of each connecting seat.

[0013] Through the above technical solution, the connecting column moves along the inside of the arc-shaped rotating groove, and the connecting seat and clamping seat are fixedly connected to the connecting column by the fixed seat.

[0014] Furthermore, the upper end of the fixed plate is provided with several guide grooves at equal intervals, and the four corners of the upper middle part of the fixed plate are provided with fixing grooves, and magnet blocks are fixedly connected to the inner side of each fixing groove.

[0015] The above technical solution uses a magnet block in the fixed groove to attract the reducer housing before clamping, thus avoiding instability caused by movement during clamping. The guide groove limits the movement of the mobile clamping unit, allowing it to move back and forth.

[0016] Furthermore, the pushing clamping unit includes a telescopic rod, the fixed end of which is fixedly connected to the inner side of the fixed plate, the telescopic end of which is fixedly connected to one side of the connecting plate, and a clamping column fixedly connected to the other side of the connecting plate, with a rubber nail fixedly connected to the inner end of each clamping column.

[0017] The above technical solution uses a fixing plate to fix the telescopic rod, pushes the clamping column with the telescopic rod, clamps the four corners of the reducer housing with the clamping column and rubber nails, and increases the convenience of connecting the telescopic rod extension end to the clamping column with a connecting plate.

[0018] Furthermore, mounting seats are fixedly connected to the front and rear sides of the fixing plate, and the inner side of the mounting seat is fixedly connected to the front and rear ends of the fixing sleeve, respectively. The outer side of the clamping column is slidably connected to the front and rear ends of the fixing sleeve. A compression block is provided in the middle of the clamping column, and springs are provided inside the fixing sleeve.

[0019] The above technical solution uses a mounting base to fix the fixing sleeve, which guides the forward and backward movement of the clamping column. At the same time, a spring pushes the compression block to increase the stability of the clamping column's movement.

[0020] Furthermore, the bottom four corners of the fixing frame are all fixedly connected to the upper end of the support leg, and the bottom end of the support leg is provided with fixing holes.

[0021] The above technical solution supports the fixed frame and its upper structure through the support legs, while the fixing holes can fix the support legs on the forging platform of the reducer housing.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when forging the reducer housing, it is necessary to fix the reducer housing. First, the rotating disk is installed in the rotating groove, and it is driven by the motor to rotate inside the rotating groove. The connecting column set at the bottom of the moving clamping unit is placed in the arc-shaped rotating groove. When the rotating disk rotates, the position of the arc-shaped rotating groove rotates, which drives the position of the connecting column at the bottom of the moving clamping unit to move. Then, the moving position of the moving clamping unit is limited in front and behind by the guide groove set on the fixed disk. The moving clamping unit follows the rotating disk and moves back and forth. Then, the front, back, left and right positions of the reducer housing are clamped by the connecting seat and the clamping seat. It is easy to control and can stably clamp reducer housings of different sizes and shapes. The clamping stability is high. It will not damage the reducer housing due to excessive clamping force, nor will it cause the reducer housing to be clamped loosely due to insufficient clamping force.

[0024] 2. In this utility model, after the reducer housing is clamped by the movable clamping unit, the clamping column is moved back and forth by the telescopic rod. The spring set inside the fixed sleeve pushes the compression block in the middle of the clamping column, so that the clamping column clamps the four corners of the reducer housing by the rubber nails. This can further increase the clamping stability after the reducer housing of different sizes and shapes is clamped by the movable clamping unit, and avoid the problem of the reducer housing shaking due to partial incomplete clamping after clamping by the movable clamping unit.
