Description

Technical Field

[0001] This utility model relates to the technical field of piston rod production equipment, and more specifically, to a fixture device for quick changeover in the friction welding process of hollow piston rods. Background Technology

[0002] Currently, with the rapid growth in car ownership, the production of various automotive parts has also increased. The shock absorber is an essential part of a vehicle, and the piston rod plays a crucial role in it.

[0003] With "energy conservation and environmental protection" becoming an increasingly important topic, lightweighting has been widely applied in the automotive industry, leading to the development of hollow piston rods. Welding, as a crucial step in the manufacturing process of hollow piston rods, directly impacts the quality of the product itself. There are many traditional piston rod welding methods, with friction welding being the most widely used. Friction welding can significantly reduce welding costs and improve welding quality, hence its widespread application.

[0004] However, the current friction welding process is quite complicated and time-consuming when changing piston rods of different diameters for welding. Moreover, most of the existing clamping devices in the piston rod friction welding process use arc surface positioning. During installation, technicians need to spend a lot of time adjusting the coaxiality of the arc surface, which reduces work efficiency. Utility Model Content

[0025] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0026] like Figure 1 As shown, this utility model provides a fixture device for quick changeover in the friction welding process of hollow piston rods, comprising:

[0027] Movable clamp 110 and clamping block 120.

[0028] Among them, such as Figure 3 As shown, the movable clamp 110 has a concave structure, and grooves are symmetrically arranged at the two top ends of the concave structure, with the grooves arranged parallel to the bottom of the concave structure.

[0029] like Figure 4 As shown, the clamping block 120 is a rectangular parallelepiped structure, and one side of the clamping block 120 is a semi-circular structure that is recessed inward. The clamping block 120 is detachably disposed in the groove of the movable clamp 110, and one side of the clamping block 120 faces the outside of the movable clamp 110.

[0030] In this embodiment, as Figure 2 As shown, the bottom of the concave structure of the movable clamp 110 is vertically and symmetrically provided with at least two threaded holes 111 for detachably fixing the movable clamp 110 to the hollow piston rod friction welding machine tool by screws.

[0031] Two pairs of through holes 132 are symmetrically provided at the two top ends of the concave structure of the movable clamp 110. That is, a pair of through holes 132 are provided on each top end of the concave structure, and the through holes 132 extend from one side of the movable clamp 110 into the groove for detachably fixing the clamping block 120 in the groove.

[0032] In this embodiment, the clamping block 120 is fixed in the groove of the movable clamp 110 by matching the bolts 131 with the through holes 132.

[0033] like Figure 1 As shown, there are two movable clamps 110, which are symmetrically arranged at intervals on the friction welding machine. The top ends of the concave structures of the two movable clamps 110 are arranged opposite each other. The two movable clamps 110 can be selectively moved closer or further apart by the friction welding machine. There are four clamping blocks 120, which are arranged one-to-one on the top ends of the concave structures of the two movable clamps 110. The clamping blocks 120 in the two movable clamps 110 are arranged opposite each other, so that the center of the clamping blocks 120 forms a circular structure, which can selectively clamp the hollow piston rod.

[0034] In this embodiment, the side of the clamping block 120 opposite to the through hole 132 is provided with a flange extending toward the moving clamp 110, that is, the side of the clamping block 120 opposite to the through hole 132 is a stepped structure, which facilitates the bolt 131 to limit the clamping block 120.

[0035] In the fixture device for quick changeover in the friction welding process of hollow piston rod provided by this utility model, the movable fixture is fixed to the friction welding machine tool by screws, and the clamping block is fixed to the movable fixture by bolts. When changing piston rods of different diameters, only the clamping block needs to be replaced.

[0036] The fixture device for quick changeover in the friction welding process of hollow piston rod provided by this utility model is convenient for changeover. Each changeover only requires loosening four screws, replacing them, and then tightening them again, which shortens the changeover time and improves work efficiency.

[0037] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
