Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical clamps, and in particular to a clamp for clamping shaft-type parts. Background Technology
[0002] Currently, in assembly lines for electric drives and other applications, most differentials are handled either by automated or manual transport.
[0003] Automated handling: Using robots, grippers, and 3D cameras, objects such as differentials are located, gripped, and transported online;
[0004] Manual handling: Items such as differentials are manually moved onto the production line.
[0005] Automated material handling: The equipment is complex, occupies a large area, and the cost is very high due to the addition of robots, 3D cameras and other materials.
[0006] Manual handling: Materials such as differentials are relatively heavy, some up to 15KG, and the production cycle is short. The disadvantage of this solution is that it greatly increases the intensity of manual labor. Utility Model Content

The outer ring of the sliding shaft is provided with a fixing ring, and the fixing ring is provided with a set of first through holes. The outer ring of the fixing ring is connected to three claw mechanisms and three connecting rods. The claw mechanism includes a first hinge seat and a hinge claw. The top of the first hinge seat is fixedly connected to the fixing ring. The first hinge seat is connected to the hinge claw through a first hinge pin. The hinge claw is connected to the sliding shaft through a second hinge pin. The connecting rod is provided with a set of second through holes. The positions of the first through holes and the second through holes are adapted to each other. The plunger is movably installed in the second through holes and the first through holes.
[0009] In this invention, a handle is provided at the top of the sliding shaft, and a lifting ring connected to the cantilever is provided at the top of the handle.
[0010] In this invention, the bottom of the sliding shaft is connected to a positioning shaft for connection with the differential and other shafts.
[0011] In this utility model, the hinge claw includes a first claw rod, a second claw rod, and a claw body. One end of the first claw rod is connected to the sliding shaft, and the other end is movably connected to the second claw rod and the first hinge seat through a second hinge pin. The claw body is bent inward.

[0018] Example:
[0019] like Figure 1 and Figure 2 This embodiment provides a clamp for gripping shaft-type parts, including a sliding shaft 2. The upper outer ring of the sliding shaft has a set of upper plunger holes and a set of lower plunger holes. A fixing ring 3 is provided on the outer ring of the sliding shaft, and the fixing ring has a corresponding set of first through holes. The outer ring of the fixing ring 3 is connected to three claw mechanisms and three connecting rods 9. Each claw mechanism includes a first hinge seat 5 and a hinge claw 6. The top of the first hinge seat is fixedly connected to the fixing ring 3. The first hinge seat 5 is connected to the hinge claw 6 via a first hinge pin 7. The hinge claw is connected to the sliding shaft 2 via a second hinge pin 8. A set of second through holes is provided on the connecting rods 9, and the positions of the first and second through holes are adapted to each other. A plunger 1 is movably installed in the second and first through holes. A handle 4 is provided on the top of the sliding shaft 2, and a lifting ring 12 connected to a cantilever is provided on the top of the handle. A positioning shaft 11 for connecting to shafts such as differentials is connected to the bottom of the sliding shaft 2. The hinge claw includes a first claw rod 6a, a second claw rod 6b, and a claw body 6c. One end of the first claw rod 6a is connected to the sliding shaft 2, and the other end is movably connected to the second claw rod 6b and the first hinge seat via a second hinge pin 8. The claw body is bent inward. The first claw rod 6a, the second claw rod 6b, and the claw body 6c are an integral structure. The connecting rod 9 is mounted on the outside of the sliding shaft 2 via a positioning seat.
[0020] In this embodiment, the working process is as follows: (1) The operator takes the suspended gripper and moves the gripper above the differential and other materials through the cantilever; (2) The plunger is manually pulled out; (3) The operator controls the cantilever to clamp the differential and other materials; (4) The materials are placed in the working position.
[0021] Working principle: The clamp is suspended on the cantilever; the clamp has 3 hooks and 1 positioning shaft. When the worker puts the positioning shaft on the differential or other materials, he pulls out the plunger. The 3 hooks use their own weight to hook the shaft and other materials, preventing the materials from falling during the movement. At the same time, the work station is equipped with a cantilever to support the weight of all clamps and materials for transfer.
[0022] This utility model provides a concept and method for clamping shaft-type parts. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
