Description

Technical Field

[0001] The utility model relates to the field of speed reducer processing equipment, in particular to a processing tool for a speed reducer frame. Background Art

[0002] The processing jigs for reducer frames are auxiliary tools designed for the processing of reducer frames, aiming to improve the processing accuracy and efficiency. These jigs play the role of fixing, positioning and guiding during the processing of the frame, ensuring the stability and accuracy of the processing process.

[0003] In the process of processing the reducer frame, it is crucial to ensure that the center of the frame is accurately aligned with the center of the jig. This alignment not only affects the accuracy and efficiency of processing, but is also directly related to the quality stability of the final product. Existing jig designs often ignore this problem, resulting in deviations between the center of the frame and the center of the jig in actual operation, which leads to a series of problems. In order to solve this problem.

[0004] There are some solutions on the market, such as using auxiliary tools such as locating pins or locating blocks, which can improve the centering accuracy of the frame to a certain extent, but the operation is complicated and inefficient. Alternatively, a movable chassis is set on the fixture, and the reducer frame is placed on the chassis. The fixture clamps the reducer frame in the center position by moving the chassis during clamping. However, the chassis is designed to be movable but cannot be effectively fixed. Then, after clamping the reducer frame, the mobility of the chassis may become a problem. This mobility may cause the position of the frame to be unstable or even offset during processing, thereby affecting the processing accuracy and effect. Utility Model Content

[0037] Reference Figure 1-Figure 5A processing jig for a reducer frame includes a base 1; a bearing plate 6, which is installed on the base 1 and is used to place the reducer frame, and the bearing plate 6 includes a plurality of through holes 7, and the through holes 7 are opened through the top of the bearing plate 6; a moving part 3 is arranged in the base 1, and the moving part 3 is arranged to move up and down on the outer ring of the positioning seat 2; the moving part 3 includes a plurality of balls 5, and the balls 5 are arranged to contact the reducer frame when passing through the through holes 7, so as to provide the reducer frame with movement on the bearing plate 6.

[0038] The rack is placed on the carrier plate 6. Before positioning the rack, the ball 5 passes through the through hole 7 and provides a movable environment for the rack. The rack can be moved to any position on the ball 5. In this way, when the first positioning portion 9 positions the rack, the center of the rack is positioned on the center of the base 1. Then, the ball 5 is controlled to withdraw from the through hole 7 and disengage from the rack. The position of the rack on the carrier plate 6 is fixed. Then, the second positioning portion 15 is used to further position the rack, which can better fix the position of the rack.

[0039] Reference Figure 1 and Figure 3 , a positioning seat 2 is installed on the base 1 and is used to fix the inner ring of the reducer frame; a plurality of first positioning parts 9 are installed on the bearing plate 6 and are used to fix the outer ring of the reducer frame; a plurality of first power sources 10 are installed on the bearing plate 6, and the power shaft of the first power source 10 is connected to the first positioning part 9; a third power source 20 is installed on the base 1, and the power shaft of the third power source 20 is installed at the bottom of the moving part 3, and is used to control the moving part 3 to move up and down on the outer ring of the positioning seat 2.

[0040] The first power source 10 adopts a cylinder or a hydraulic cylinder. The third power source 20 adopts a linear motor or a cylinder. The first power source 10 controls the movement of the first positioning part 9. The number of the multiple first positioning parts 9 is at least three. The multiple first positioning parts 9 simultaneously position the outer ring of the frame and position the frame at the center of the base 1. The third power source 20 controls the moving part 3 to move downward, so that the ball 5 is disengaged from the through hole 7, the frame cannot continue to move on the supporting plate 6, and the position of the frame can be stabilized.

[0041] Reference Figure 4 and Figure 5A mounting groove 8 is provided at the top of the base 1, and the positioning seat 2 is installed on the bottom wall of the mounting groove 8. A plurality of grooves 4 are provided at the top of the moving part 3, and the ball 5 is installed in the groove 4. The positioning seat 2 includes: a fixing groove 11, which is provided at the top of the positioning seat 2, and a plurality of moving holes 13 are provided on the inner wall of the fixing groove 11; a conical seat 12, which is installed in the fixing groove 11; a plurality of telescopic rods 14, which are inclinedly arranged at one end close to the conical seat 12 and fit with the conical seat 12, and are arranged so that when the conical seat 12 moves downward, the plurality of telescopic rods 14 move simultaneously to the end away from the conical seat 12; a plurality of second positioning parts 15, which are installed at one end of the telescopic rods 14, and a second power source 16 is installed on the bottom wall of the fixing groove 11, and a power shaft of the second power source 16 is connected to the bottom of the conical seat 12, so as to control the conical seat 12 to move up and down in the fixing groove 11.
