[0025] Example 1

[0026] like Figure 1 As shown, this embodiment provides a workpiece hydraulic support device, including a hydraulic jack 1 and a placement plate 8. The hydraulic jack 1 is fitted with a three-legged bracket 2 to increase the overall stability of the hydraulic jack 1. It should be noted that the two are fixed by pipe clamps or clamps. The output end of the hydraulic jack 1 has an annular insertion hole 3. The connecting rod 4 located at the top of the hydraulic jack 1 is connected to the insertion hole 3 through an annular protrusion at the bottom and is fixed by insertion, which facilitates subsequent disassembly operations. The top of the connecting rod 4 is fixed with a threaded tube 5. The threaded tube 5 is internally threaded with a threaded rod 6, and the outer edge of the threaded rod 6 is sprayed with scale marks. The direction of the placement plate 8 is adjusted by rotating the thread. The top of the threaded rod 6 is fixed with a placement plate 8 for clamping the workpiece.

[0027] The left and right ends of the shelf 8 are provided with inner cavities. Each inner cavity is connected to an L-shaped telescopic side plate 9 by a set of springs. The workpiece is clamped by the L-shaped bend and the clamping is stabilized by the spring rebound. The working surface of the telescopic side plate 9 is fixed with two side pads 11 located at the edge. The purpose is to increase stability when clamping the workpiece and reduce wear at the contact end. The middle of the shelf 8 is provided with a positioning hole 10. The top of the threaded rod 6 is fixed with a telescopic spring positioning pin 7 that passes through the positioning hole 10. The telescopic spring positioning pin 7 is used to reinforce the annular workpiece. It pops out after being pressed and passes through the inner hole of the annular workpiece to increase the limiting effect.

[0028] Still include two special-shaped fixed side plates 14, the non-working surface of two special-shaped fixed side plates 14 is fixed with pin shaft 13, the telescopic end of two telescopic side plates 9 is provided with movable slot 12 for being inserted with pin shaft 13, and the action is to clamp the special-shaped workpiece, if using telescopic side plate 9 to clamp, it will appear that it cannot reach a more fitted position because it cannot adjust the fitting angle, the special-shaped fixed side plate 14 can be individually rotated to clamp the outside of the special-shaped workpiece, and parallel or intersecting direction clamping processing (such as / / shape or eight-character shape) can be realized.

[0029] Its working principle is as follows:

[0030] After adjusting the hydraulic jack 1 to the appropriate height, the workpiece is placed on the placing plate 8, and the two sides are clamped by the telescopic side plate 9 (if the angle is not suitable, the threaded rod 6 can be rotated to adjust, and then the height of the hydraulic jack 1 needs to be adjusted according to the rotating height), and for polygonal workpieces, the pin shaft 13 is inserted to be clamped by the rotatable special-shaped fixed side plate 14 on the outer surface, and the rotating side is contacted by the side pad 11 to realize stable effect.

[0031] Example 2

[0032] The difference between this embodiment and example 1 is that, as shown in Figure 2 Suitable for clamping polygon, such as two special-shaped fixed side plates 14 in example 1 have good stability for hexagonal clamping, and for twelve deformation, the clamping contact surface is smaller, so a set of two special-shaped fixed side plates 14 can be added to clamp different angles, and good clamping effect is achieved.

[0033] It should be noted that the structure of the utility model can be realized in many different forms, and is not limited to the described embodiments, and any equivalent transformation made by those skilled in the art using the contents of the utility model specification and drawings, or direct or indirect application in other related technical fields, such as other article loading and unloading, are all included in the protection scope of the utility model.
