Abstract
Description
Technical Field
[0001] The utility model belongs to the field of workpiece loading or clamping devices, in particular to a clamping fixture. Background Art
[0002] Figure 1 The product shown is a reducer output planetary frame, which includes a cylindrical platform and a triangular disk arranged on the cylindrical platform, and each vertex of the triangular disk is provided with a through hole. When processing the through holes of the reducer output planetary frame, the following steps are usually adopted: S1: fix the reducer output planetary frame with a clamping fixture, and then use a bench drill to process a through hole; S2: after the processing is completed, remove the reducer output planetary frame from the clamping fixture, change the direction, fix it with the clamping fixture again, and use the bench drill to process the next through hole; S3: repeat step S2 to complete the processing of the third through hole.
[0003] In the above through-hole processing method, one reducer output planetary frame needs to be clamped three times, which is time-consuming and labor-intensive, and is not conducive to the fast and efficient processing of the through-holes of the reducer output planetary frame. Therefore, it is of great significance to provide a clamping fixture for the reducer output planetary frame that can reduce the product clamping time and can quickly and efficiently process all through-holes. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies and defects mentioned in the above background technology and provide a clamping fixture for the output planetary frame of the reducer which can reduce the product clamping time and can quickly and efficiently process all through holes.
[0005] In order to solve the above technical problems, the technical solution proposed by the utility model is:
[0006] A clamping fixture for a reducer output planetary frame, the reducer output planetary frame includes a cylindrical table and a triangular disk arranged on the cylindrical table, each vertex of the triangular disk is provided with a through hole, and the bottom surface of the cylindrical table is provided with a non-circular groove. The clamping fixture includes a frame body, the frame body is provided with a circular groove, a positioning cylinder (rotatably arranged, matching in size) is provided in the circular groove, the positioning cylinder is provided with a non-circular clamping column for cooperating with the non-circular groove and for clamping the cylindrical table on the positioning cylinder, the side of the positioning cylinder is evenly provided with a plurality of pits, and the frame body is provided with a plurality of ball screws cooperating with the pits.
[0007] In the above-mentioned clamping fixture, preferably, the vertex of the triangular disk is a curved surface, the frame body is provided with an upper boss, the side surface of the upper boss is a curved surface, and the side surface of the upper boss is provided with a curved surface segment that completely matches the curved surface at the vertex of the triangular disk. The above-mentioned arrangement is conducive to the rotation positioning of the output planet carrier of the reducer.
[0008] In the above-mentioned clamping fixture, preferably, the frame is provided with a through hole processing avoidance groove. During processing, the reducer output planetary frame can be rotated so that the through hole processing position corresponds to the through hole processing avoidance groove, so that when the through hole is processed by the bench drill, it will not be affected by the frame.
[0009] In the above-mentioned clamping fixture, preferably, the positioning cylinder is provided with a mounting groove, the lower end of the non-circular clamping column is installed in the mounting groove, and a pin is also provided between the positioning cylinder and the non-circular clamping column, the middle part of the pin passes through the non-circular clamping column, and the two ends of the pin are clamped in the positioning cylinder. The above-mentioned pin arrangement method is conducive to the close cooperation between the non-circular clamping column and the positioning cylinder, and the output planetary carrier of the reducer can be better fixed on the frame.
[0010] In the above-mentioned clamping fixture, preferably, the non-circular groove is a regular hexagonal groove, and the non-circular clamping column is a regular hexagonal clamping column.
[0011] In the above-mentioned clamping fixture, preferably, six pits are evenly arranged on the side of the positioning cylinder, and two ball screws are arranged in the frame body. The above-mentioned six pits are evenly arranged, one is arranged every 60°, and the position of the output planetary frame of the reducer is adjusted by 2 pits each time. The use of two ball screws can better achieve the position adjustment of the output planetary frame of the reducer.
[0012] The clamping fixture for the output planetary frame of the reducer of the utility model can fix the output planetary frame of the reducer on the non-circular clamping column through the cooperation of the non-circular clamping column and the non-circular groove. The non-circular clamping column is connected to the positioning cylinder, which is equivalent to fixing the output planetary frame of the reducer on the positioning cylinder. The positioning cylinder is rotatably arranged in the circular groove (the rotation is limited by the pit and the ball screw). After processing a through hole, it is only necessary to rotate the positioning cylinder to the next through hole processing station to realize the processing of the next through hole. Rotate again to realize the processing of the last through hole. With the above-mentioned clamping and processing method, after processing a through hole each time, there is no need to remove the output planetary frame of the reducer and re-clamp it. It is only necessary to rotate the output planetary frame of the reducer. This can greatly reduce the clamping time of the product, save manpower, and help improve processing efficiency.
[0013] In the utility model, the rotation of the positioning cylinder in the circular groove is limited, so that the processing position can be fixed and adjusted. Specifically, there is a movable ball at the front end of the ball screw, and the ball can be stuck in the pit to limit the position of the positioning cylinder. At this time, the first processing position can be fixed. When the processing position needs to be adjusted, a large rotational torque can be applied to the positioning cylinder (the output planetary frame of the reducer can be manually rotated) so that the ball can retract. At this time, the positioning cylinder can be rotated. When it rotates to the next pit, the ball will automatically pop out and get stuck in the pit, fixing the positioning cylinder at the next position. The above operation method can be used to adjust the processing position.
[0014] Compared with the prior art, the advantages of the utility model are:
[0015] The clamping fixture for the output planetary frame of the reducer of the utility model fixes the output planetary frame of the reducer on the positioning cylinder, and the positioning cylinder is rotatably arranged in the circular groove. After processing a through hole, it is only necessary to rotate the positioning cylinder to the next through hole processing station to realize the processing of the next through hole, and rotate it again to realize the processing of the last through hole. With the above clamping and processing method, after processing a through hole each time, it is not necessary to remove the output planetary frame of the reducer and re-clamp it. It is only necessary to rotate the output planetary frame of the reducer, which can greatly reduce the product clamping time, save manpower, and is conducive to improving processing efficiency.
