Description

Technical Field

[0001] The utility model relates to the field of workpiece clamping devices, and specifically to a tooling fixture for end cover processing. Background Technique

[0002] The end cover is a main component of the transmission part in many existing devices. It protects the bearings rotating at high speed. Therefore, the processing accuracy of the end cover, the deformation strength of the material, and the quality of the end cover determine the performance of the transmission device, and even affect the stability, safety, reliability of the entire mechanical equipment and the service life of the equipment. During the processing of the end cover, it needs to be processed on a CNC machining center. Before processing, the end cover needs to be fixed by a fixture.

[0003] After retrieval, the utility model patent with the publication number of CN219665832U discloses a tooling fixture for end cover processing, including long slide bars. Connecting columns are arranged at the middle positions on the left sides of the two long slide bars. Output ends on the opposite sides of the two first motors are fixedly connected with semi-circular fixing clips. The bottom end position of the connecting column on the right side is slidably connected with an L-shaped fixing plate. The output end at the right side of the second motor is fixedly connected with a reciprocating lead screw. The output end at the right side of the second motor is fixedly connected with a reciprocating lead screw. In this device, the semi-circular fixing clip can rotate back and forth, which can meet the processing of different positions of the end cover. The reciprocating lead screw at the bottom will move back and forth, facilitating the worker to move and install the end cover for processing. The slider moves back and forth along with the rolling of the reciprocating lead screw, greatly improving the stability of the processing conditions.

[0004] However, in practical applications, this device can only clamp and fix one end cover. After processing one end cover, the end cover can be disassembled and the next end cover can be installed. The processing efficiency is relatively low and it is difficult to meet the usage requirements. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that the existing tooling fixture for end cover processing can only clamp and fix one end cover, resulting in relatively low processing efficiency of the end cover.

[0006] To solve the above problems, the technical solution of the utility model is: a tooling fixture for end cover processing, including a base and a bearing plate rotatably installed on the top of the base. A support column is fixedly connected to the top of the bearing plate, a top plate is fixedly connected to the top of the support column, a fixed ring is fixedly connected to the outside of the top plate, a plurality of fixed seats are fixedly connected to the outside of the fixed ring, a rotary cylinder II is installed on the fixed seat, a fixed frame is installed at the output end of the rotary cylinder II, and a positioning member for fixing the end cover is fixedly connected to one end of the fixed frame.

[0007] Further, a fixing groove is provided on the top surface of the base, and a rotary cylinder I is installed inside the fixing groove. The output end of the rotary cylinder I is connected to the bearing plate.

[0008] Further, a plurality of rollers are installed at the bottom edge of the bearing plate, and an annular groove adapted to the rollers is provided on the top surface of the base.

[0009] Further, the positioning member includes a positioning seat. A through groove is provided in the middle of the positioning seat, and a clamping plate with a V-shaped structure is movably installed inside the through groove. A V-shaped groove adapted to the clamping plate is provided at one end of the through groove away from the fixing frame.

[0010] Further, an electric push rod is installed inside the fixing frame, and the movable end of the electric push rod extends into the through groove and is connected to the clamping plate.

[0011] The advantages of the present utility model compared with the existing technology are as follows: By the telescopic movement of the electric push rod, the clamping plate is promoted to move, and in cooperation with the V-shaped groove, the clamping and fixing of the end cover are realized. Through the arrangement of a plurality of positioning members, the clamping and fixing of a plurality of end covers can be achieved simultaneously. In cooperation with the rotary cylinder I and the rotary cylinder II, the continuous processing of the end cover can be realized, and the processing efficiency of the end cover is improved.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0018] As Figure 1 , Figure 2 and Figure 3 shown, a tooling fixture for end cover processing includes a base 1 and a bearing plate 2 rotatably mounted on the top of the base 1. A fixing groove is provided on the top surface of the base 1, and a rotary cylinder 9 is installed inside the fixing groove. The output end of the rotary cylinder 9 is connected to the bearing plate 2. A plurality of rollers 10 are installed at the bottom edge of the bearing plate 2, and an annular groove adapted to the rollers 10 is provided on the top surface of the base 1. A support column 3 is fixedly connected to the top of the bearing plate 2, a top plate 4 is fixedly connected to the top of the support column 3, a fixing ring 5 is fixedly connected to the outside of the top plate 4, and a plurality of fixing seats 6 are fixedly connected to the outside of the fixing ring 5.

[0019] When the rotary cylinder 9 works, it will drive the bearing plate 2 to rotate by a set angle. The bearing plate 2 drives the top plate 4, the fixing ring 5 and the fixing seat 6 to rotate through the support column 3, so as to realize the angle adjustment of the fixing seat 6.

[0020] The rollers 10 can support the bearing plate 2 to ensure the normal rotation of the bearing plate 2.

[0021] As Figure 2 and Figure 4 shown, a rotary cylinder 7 is installed on the fixing seat 6, and a fixing frame 8 is installed at the output end of the rotary cylinder 7. One end of the fixing frame 8 is fixedly connected with a positioning member for fixing the end cover. The positioning member includes a positioning seat 11. A through groove is provided in the middle of the positioning seat 11, and a V-shaped clamping plate 12 is movably installed inside the through groove. A V-shaped groove adapted to the clamping plate 12 is provided at one end of the through groove away from the fixing frame 8. An electric push rod 13 is installed inside the fixing frame 8, and the movable end of the electric push rod 13 extends into the through groove and is connected to the clamping plate 12.

[0022] Place the end cover to be processed in the through groove. The electric push rod 13 extends, so that the clamping plate 12 moves towards the V-shaped groove, and cooperates with the V-shaped groove to realize the clamping and fixing of the end cover. The rotary cylinder 7 drives the fixing frame 8 to rotate, so as to realize the angle adjustment of the end cover, and thus the processing of different surfaces of the end cover can be realized.

[0023] In specific use, according to the number requirement of the machined surfaces of the end cover, multiple processing stations are set. The end cover is placed in the through groove, and the electric push rod 13 extends to drive the clamping plate 12 to move, so as to realize the clamping and fixing of the end cover. The rotary cylinder 9 drives the fixed ring 5 and the fixed seat 6 to rotate, realizing the adjustment of the angle of the fixed seat 6, that is, the end cover can be moved from the feeding station to the processing station. According to the same steps, the end cover can pass through multiple processing stations in sequence. When reaching each processing station, the rotary cylinder 7 drives the fixed frame 8 to rotate, realizing the adjustment of the angle of the end cover, and thus multi-surface machining of the end cover can be realized. Through the setting of multiple positioning parts, multiple end covers can be clamped and fixed at the same time, continuous machining of the end cover can be realized, and the machining efficiency of the end cover can be improved.
