Description

Technical Field

[0001] The utility model relates to the technical field of cage processing equipment, in particular to a three-jaw fixture for processing a constant velocity joint cage. Background Art

[0002] The constant velocity joint is one of the important transmission components on an automobile engine. For the inner and outer spherical surface dimensions of the constant velocity joint cage, the center offset error of the inner and outer spherical surfaces, and the geometric tolerance accuracy requirements are very high. Since the wall of the constant velocity joint cage is relatively thin, it is easy to deform during processing. At present, the clamping equipment for the constant velocity joint cage is inconvenient to use, cannot quickly and accurately position, and the force is unevenly distributed.

[0003] To solve the above problems, the prior art patent (CN215617514U) discloses a three-jaw fixture for processing a constant velocity joint cage, including a base. A center plate is fixedly provided at the center of the top of the base. A cage placement groove is opened at the top of the center plate. A guide post is fixedly provided at the center of the top of the center plate. A buffer spring fixed to the center plate is sleeved outside the guide post. A sleeve screwed outside the guide post is provided above the buffer spring. An installation ring integrally formed with the sleeve is provided at the top of the sleeve. A three-jaw assembly driven by a cylinder is provided on the side wall of the installation ring. When the utility model is used, the cage is placed on the center plate and located in the cage placement groove. The sleeve is sleeved outside the guide post and screwed on the guide post. The cylinder drives the movable ring to move up and down along the sleeve, thereby realizing the opening and closing of the three-jaw assembly, and thus the cage can be clamped. Since the cage is clamped by the three-jaw assembly, it can be quickly and accurately positioned, and the force distribution is uniform.

[0004] However, in the above prior art, when the size of the constant velocity joint cage changes, the contact surface between the fixture after expansion and the constant velocity joint cage is in an inclined state, which is easy to cause damage to the inside of the constant velocity joint cage. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a three-jaw fixture for processing a constant velocity joint cage, which solves the technical problem that when the size of the constant velocity joint cage changes in the prior art, the contact surface between the fixture after expansion and the constant velocity joint cage is in an inclined state, which is easy to cause damage to the inside of the constant velocity joint cage.

[0006] To achieve the above object, a three-jaw fixture for processing a constant velocity joint cage adopted by the present utility model includes an operating table, a drive box, a cover plate and a fixing component. The drive box is fixedly connected to the operating table and is located above the operating table. The cover plate is detachably connected to the drive box and is located above the drive box. The fixing component includes a driving member, three clamping members, a rotating shaft, a triangular disc and three linkage members. The driving member is fixedly connected to the drive box and is located inside the drive box. The three clamping members are circumferentially distributed along the axial center line of the triangular disc. Each clamping member includes a slide rail, a sliding block, a push rod and a clamping claw. The slide rail is fixedly connected to the drive box and is located inside the drive box. The sliding block is slidably connected to the slide rail and is located above the slide rail. The push rod is fixedly connected to the sliding block and is located outside the sliding block. The clamping claw is fixedly connected to the push rod and is located outside the push rod. The rotating shaft is rotatably connected to the drive box and is located inside the drive box. The triangular disc is fixedly connected to the rotating shaft and is located outside the rotating shaft. The three linkage members are rotatably connected to the triangular disc and are located below the push rod.

[0007] Among them, the driving member includes a base and a fixing plate. The base is fixedly connected to the operating table and is located outside the drive box. The fixing plate is fixedly connected to the drive box and is located outside the triangular disc.

[0008] Among them, the driving component further includes a driving motor, a driving rod and a moving block. The output end of the driving motor is fixedly connected to one end of the driving rod and is located above the base. The other end of the driving rod is rotatably connected to the fixing plate and is located outside the slide rail. And the surface of the driving rod has a thread. The moving block is threadedly connected to the driving rod and is located outside the sliding block.

[0009] Among them, each linkage member includes a connecting frame and a linkage rod. The connecting frame is fixedly connected to the sliding block and is located below the push rod. The linkage rod is rotatably connected to the connecting frame and is located outside the triangular disc.

[0010] Among them, the drive box has a through groove.

[0011] Among them, the three-jaw fixture for processing a constant velocity joint cage further includes three soft pads and a protective cover. The three soft pads are respectively fixedly connected to the three clamping claws and are located outside the clamping claws. The protective cover is detachably connected to the driving motor and is located outside the driving motor.

[0012] A three-jaw fixture for processing a constant velocity joint cage of the present utility model, when in specific use, places the constant velocity joint cage outside the clamping jaws. The driving member operates to drive the sliding block to slide outward on the slide rail. The push rod drives the clamping jaws to move outward, and through the linkage member, the triangular disc rotates around the rotating shaft, causing the other two groups of clamping jaws to move outward simultaneously. The constant velocity joint cage is fixed by the simultaneous lateral outward movement of the three clamping jaws. This method can effectively solve the problem that the contact surface between the fixture and the constant velocity joint cage is in an inclined state after the fixture is unfolded.

[0023] For this specific embodiment, the drive box 102 is fixedly connected to the workbench 101 and is located above the workbench 101. The cover plate 103 is detachably connected to the drive box 102 and is located above the drive box 102. The fixing assembly includes a driving member, three clamping members, a rotating shaft 104, a triangular disc 105, and three linkage members. The driving member is fixedly connected to the drive box 102 and is located inside the drive box 102. The three clamping members are circumferentially distributed along the axial center line of the triangular disc 105. Each clamping member includes a slide rail 106, a sliding block 107, a push rod 108, and a clamping claw 109. The slide rail 106 is fixedly connected to the drive box 102 and is located inside the drive box 102. The sliding block 107 is slidably connected to the slide rail 106 and is located above the slide rail 106. The push rod 108 is fixedly connected to the sliding block 107 and is located outside the sliding block 107. The clamping claw 109 is fixedly connected to the push rod 108 and is located outside the push rod 108. The rotating shaft 104 is rotatably connected to the drive box 102 and is located inside the drive box 102. The triangular disc 105 is fixedly connected to the rotating shaft 104 and is located outside the rotating shaft 104.

The cover plate 103 facilitates the maintenance of the structure inside the drive box 102. Place the constant velocity joint cage outside the clamping claw 109. The driving member operates to drive the sliding block 107 to slide outward on the slide rail 106. The push rod 108 drives the clamping claw 109 to move outward, and through the linkage member, the triangular disc 105 rotates around the rotating shaft 104, causing the other two clamping claws 109 to move outward simultaneously. The constant velocity joint cage is fixed by the simultaneous lateral outward movement of the three clamping claws 109. This method can effectively solve the problem that the contact surface between the fixture and the constant velocity joint cage is in an inclined state after the fixture is unfolded.

[0024] Wherein, the base 110 is fixedly connected to the workbench 101 and is located outside the drive box 102. The fixing plate 111 is fixedly connected to the drive box 102 and is located outside the triangular disc 105. The base 110 is fixed above the workbench 101.

The other end of the driving rod 113 is rotatably connected to the fixing plate 111 and is located outside the slide rail 106. The surface of the driving rod 113 has threads. The moving block 114 is threadedly connected to the driving rod 113 and is located outside the sliding block 107. The base 110 fixes the driving motor 112. The driving motor 112 drives the driving rod 113 to rotate. The driving rod 113 rotates outside the fixing plate 111. The moving block 114 drives the sliding block 107 to move.

[0026] Meanwhile, the connecting frame 115 is fixedly connected to the sliding block 107 and is located below the pushing rod 108. The linkage rod 116 is rotatably connected to the connecting frame 115 and is located outside the triangular disc 105. The sliding block 107 drives the connecting frame 115 to move simultaneously. The pushing rod 108 pushes the linkage rod 116 through the connecting frame 115 to achieve a rotational connection with the triangular disc 105, so as to drive the triangular disc 105 to rotate when the connecting frame 115 moves.

[0027] In addition, the driving box 102 has a through groove 117, and the through groove 117 of the driving box 102 is convenient for cleaning the internal impurities during the processing operation of the constant velocity joint cage.

[0028] When using a three-jaw clamp for processing a constant velocity joint cage according to this embodiment, by setting the driving box 102, the cover plate 103 and the fixing component, during specific use, the driving box 102 is fixed above the operating table 101. The cover plate 103 is convenient for maintaining the structure inside the driving box 102. The constant velocity joint cage is placed outside the clamping claws 109. The driving motor 112 drives the driving rod 113 to rotate. The moving block 114 drives the sliding block 107 to move. The sliding block 107 slides outward on the slide rail 106. The pushing rod 108 drives the clamping claws 109 to move outward. The sliding block 107 drives the connecting frame 115 to move simultaneously. The pushing rod 108 pushes the linkage rod 116 through the connecting frame 115 to achieve a rotational connection with the triangular disc 105, so as to drive the triangular disc 105 to rotate around the rotating shaft 104 when the connecting frame 115 moves, enabling the other two groups of clamping claws 109 to move outward simultaneously. The constant velocity joint cage is fixed by the simultaneous lateral outward movement of the three clamping claws 109. In this way, constant velocity joint cages of different sizes can be fixed, and through the lateral movement of the clamp, the contact surface with the constant velocity joint cage can be effectively prevented from being in an inclined state, improving the protection of the clamp for the constant velocity joint cage.
