A lifting and clamping fixture for rim machining

Abstract

This utility model relates to the field of lifting clamp technology, and in particular to a lifting clamp for wheel rim processing. By aligning the center hole of the wheel rim with a clamping rod and inserting it, the wheel rim can be clamped onto the clamping rod. Two clamping rods can simultaneously clamp two wheel rims, allowing for simultaneous lifting and transport of two wheel rims. When the center hole of the wheel rim is inserted into the clamping rod, it contacts a clamping block on the clamping rod, causing the clamping block to be compressed and the spring to deform, resulting in synchronous contraction of the clamping block. When the center hole of the wheel rim moves to the innermost side of the clamping rod, it disengages from the clamping block, allowing the spring to return to its original position, and the clamping block to return to its original position simultaneously. Thus, the clamping block constrains the wheel rim clamped onto the clamping rod, preventing it from detaching. Furthermore, when the wheel rim needs to be removed from the clamping rod, it can be easily pulled outwards, making removal convenient. Therefore, the wheel rim is easy to clamp, lift, and disassemble.

Description

Technical Field

[0001] This utility model relates to the field of lifting fixture technology, and in particular to a lifting and clamping fixture for wheel rim processing. Background Technology

[0002] The wheel rim is the component around which the tire is mounted. Also known as the wheel hub, it is a rotating assembly connecting the wheel and axle, responsible for bearing the load between the tire and the axle. The function of the wheel rim is to share the load on the wheel with the tire and dissipate the heat generated by the tire.

[0003] The processing of wheel rims is complex and requires several steps on the production line. Wheel rims need to be transported via guide rails, and lifting fixtures are required to hold them in place. However, existing lifting fixtures are ineffective because they make it difficult to lift the rims, result in unstable lifting, and the rims are prone to detaching from the clamps. Furthermore, the lifting height is difficult to adjust, making them impractical. Therefore, we propose a lifting fixture for wheel rim processing to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the prior art by proposing a lifting and clamping fixture for rim processing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lifting and clamping fixture for rim processing, comprising a lifting rod, clamping rods, a central column, a through groove, a frame, springs, a clamping block, a first threaded hole, a telescopic rod, a second threaded hole, a threaded rod, a mounting frame, a first through hole, a moving block, a second through hole, a pin, and a guide rail. Clamping rods are fixedly connected to both sides of the bottom of the lifting rod. A central column is fixedly connected to the center of the clamping rod. Through grooves are provided on the surface of the clamping rod in all directions. A frame is fixedly connected to the central column in all directions. Springs are fixedly connected to both sides of the inside of the frame. The tops of the springs are all fixedly connected to... A clamping block is fixedly connected, and the clamping block corresponds to the through groove inside. A first threaded hole is fixedly connected to the top surface of the lifting rod. A telescopic rod is movably connected inside the lifting rod. The surface of the telescopic rod is provided with multiple second threaded holes. The threaded rod is threaded into the first threaded hole and the second threaded hole. A mounting frame is fixedly connected to the top of the telescopic rod. A first through hole is provided on both sides of the mounting frame. A moving block is movably connected inside the mounting frame. A second through hole is provided in the middle of the moving block. A pin passes through the first through hole and the second through hole to lock the mounting frame. A guide rail is slidably connected to the top of the moving block.

[0006] Preferably, the two clamps are arranged in a symmetrical structure.

[0007] Preferably, the clamping blocks are arranged in a cross-shaped structure.

[0008] Preferably, the clamping block is arranged in an arc shape.

[0009] Preferably, the telescopic rod is adapted to the interior of the boom.

[0010] Preferably, the cross-sections of the first through hole and the second through hole are both square, and the pin is adapted to the interior of the first through hole and the second through hole.

[0011] Compared with the prior art, this utility model has the following advantages: (1) By aligning the center hole of the rim with the clamping rod and inserting it, the rim can be clamped onto the clamping rod. Two rims can be clamped simultaneously by two clamping rods, allowing the lifting rod to lift and transport two rims at the same time. When the center hole of the rim is aligned with the clamping rod and inserted, the center hole of the rim can contact the clamping block on the clamping rod, causing the clamping block to be squeezed and the spring to deform and compress, allowing the clamping block to contract synchronously. When the center hole of the rim moves to the innermost side of the clamping rod, it can disengage from the clamping block, allowing the spring to return to its original position, allowing the clamping block to return to its original position synchronously. Thus, the clamping block can constrain the rim clamped onto the clamping rod, preventing the rim from disengaging from the clamping rod. When it is necessary to remove the rim from the clamping rod, the rim can be pulled outward to complete the removal, making it easy to pick up and lift the rim and disassemble it.

[0012] (2) The lifting height of the rim can be adjusted by the telescopic rod moving up and down inside the lifting rod, which can improve its practicality. The lifting height can be locked and fixed by the threaded rod being threaded into the first threaded hole and the second threaded hole. Attached Figure Description

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] like Figure 1-5 The illustrated lifting and clamping fixture for wheel rim processing includes a lifting rod 1, clamping rods 2, a central column 3, a through groove 4, a frame 5, a spring 6, a clamping block 7, a first threaded hole 8, a telescopic rod 9, a second threaded hole 10, a threaded rod 11, a mounting frame 12, a first through hole 13, a moving block 14, a second through hole 15, a pin 16, and a guide rail 17. Clamping rods 2 are fixedly connected to both sides of the bottom of the lifting rod 1. A central column 3 is fixedly connected to the center of the clamping rod 2. Through grooves 4 are provided on the surface of the clamping rod 2 in all directions. A frame 5 is fixedly connected to the central column 3 in all directions. Springs 6 are fixedly connected to both sides of the inside of the frame 5. Clamping blocks 7 are fixedly connected to the top of each spring 6. The clamping block 7 and the through slot 4 are connected through and correspond to each other. The top surface of the lifting rod 1 is fixedly connected to the first threaded hole 8. The inside of the lifting rod 1 is movably connected to the telescopic rod 9. The surface of the telescopic rod 9 is provided with multiple second threaded holes 10. The threaded rod 11 is threaded into the first threaded hole 8 and the second threaded hole 10. The top of the telescopic rod 9 is fixedly connected to the mounting frame 12. The two sides of the mounting frame 12 are provided with first through holes 13. The inside of the mounting frame 12 is movably connected to the moving block 14. The middle of the moving block 14 is provided with a second through hole 15. The pin 16 passes through the first through hole 13 and the second through hole 15 to lock the mounting frame 12. The top of the moving block 14 is slidably connected to the guide rail 17.

[0017] In this embodiment, the two clamping rods 2 are arranged in a symmetrical structure.

[0018] In practical use, the wheel rim is inserted by aligning the center hole of the wheel rim with the clamping rod 2, so that the wheel rim can be clamped onto the clamping rod 2. The two clamping rods 2 can clamp two wheel rims at the same time, so that the lifting rod 1 can lift and transport two wheel rims at the same time.

[0019] In this embodiment, the clamping blocks 7 are arranged in a cross-shaped structure.

[0020] In practical use, when the center hole of the wheel rim is aligned with the clamping rod 2 and inserted, the center hole of the wheel rim can contact the clamping block 7 on the clamping rod 2, so that the clamping block 7 can be squeezed and the spring 6 can be deformed and compressed, so that the clamping block 7 can retract synchronously. When the center hole of the wheel rim moves to the innermost side of the clamping rod 2, it can disengage from the clamping block 7, so that the spring 6 can return to its original position, so that the clamping block 7 can return to its original position synchronously. Thus, the clamping block 7 can constrain the wheel rim clamped on the clamping rod 2, which can prevent the wheel rim from disengaging from the clamping rod 2. When it is necessary to remove the wheel rim from the clamping rod 2, the wheel rim can be pulled outward to complete the removal, thus making the wheel rim easy to clamp and lift.

[0021] In this embodiment, the clamping block 7 is arranged in an arc shape.

[0022] In practical use, the arc-shaped structure of the holding block 7 allows the center hole of the wheel rim to better contact the holding block 7, thus enabling better compression of the holding block 7.

[0023] In this embodiment, the telescopic rod 9 is adapted to the interior of the hanging rod 1.

[0024] In practical use, the lifting height of the wheel rim can be adjusted by the telescopic rod 9 moving up and down inside the lifting rod 1, which improves practicality. The lifting height can be locked and fixed by the threaded rod 11 threaded into the first threaded hole 8 and the second threaded hole 10.

[0025] In this embodiment, the cross-sections of the first through hole 13 and the second through hole 15 are both square, and the pin 16 is adapted to the interior of the first through hole 13 and the second through hole 15.

[0026] In practical use, by pulling the pin 16 out from the first through hole 13 and the second through hole 15, the hoisting body can be removed from the guide rail 17, making it easy to disassemble and replace the hoisting body.

[0027] The fact that both the first through hole 13 and the second through hole 15 have square cross-sections ensures that the hoisting body will not rotate or move.

[0028] The working principle of a lifting and clamping fixture for rim processing mentioned in this utility model: In use, the wheel rim is inserted by aligning the center hole of the wheel rim with the clamping rod 2, so that the wheel rim can be clamped onto the clamping rod 2. Two wheel rims can be clamped at the same time by the two clamping rods 2, so that the lifting rod 1 can lift and transport two wheel rims at the same time. Meanwhile, when the center hole of the wheel rim is aligned with the clamping rod 2 and inserted, the center hole of the wheel rim can contact the clamping block 7 on the clamping rod 2, so that the clamping block 7 can be squeezed and the spring 6 can be deformed and compressed, so that the clamping block 7 can retract synchronously. When the center hole of the wheel rim moves to the innermost side of the clamping rod 2, it can disengage from the clamping block 7, so that the spring 6 can return to its original position, so that the clamping block 7 can return to its original position synchronously. Thus, the clamping block 7 can constrain the wheel rim clamped on the clamping rod 2, which can prevent the wheel rim from disengaging from the clamping rod 2. When it is necessary to remove the wheel rim from the clamping rod 2, the wheel rim can be pulled outward to complete the removal, thus making the wheel rim easy to clamp and lift. Meanwhile, the arc-shaped structure of the holding block 7 allows the center hole of the wheel rim to better contact the holding block 7, thus better squeezing the holding block 7. Meanwhile, the lifting height of the wheel rim can be adjusted by the telescopic rod 9 moving up and down inside the lifting rod 1, which improves its practicality. The lifting height can be locked and fixed by the threaded rod 11 threaded into the first threaded hole 8 and the second threaded hole 10.

[0029] Meanwhile, by pulling the pin 16 out of the first through hole 13 and the second through hole 15, the hoisting body can be removed from the guide rail 17, making it easy to disassemble and replace the hoisting body.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
