Description

Technical Field

[0001] The utility model relates to the technical field of positioning tooling, in particular to a positioning tooling for an automobile frame. Background Art

[0002] In automobile manufacturing and maintenance, the positioning of the frame is a key step to ensure vehicle assembly accuracy and maintenance quality. It needs to be positioned by positioning tooling to prevent the frame from shifting.

[0003] Currently, a positioning fixture for automobile frames mostly relies on a combination of positioning columns and positioning holes to achieve frame positioning and fixation. This method exhibits poor stability and is therefore prone to frame offset during welding, which is not conducive to subsequent use. At the same time, most of these fixtures cannot adjust the horizontality of the frame, so during assembly, it is easy to reduce the assembly accuracy between the frame and the assembly components, thereby reducing the overall performance and safety of the frame.

[0004] In summary, the present invention solves the problems in the above-mentioned background technology by designing a positioning tool for an automobile frame. Utility Model Content

[0005] The purpose of the present utility model is to provide a positioning tool for an automobile frame to solve the problems raised in the above background technology.

[0007] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0008] As a preferred solution of the present invention, the synchronous electric push rods are respectively located on the top side of the support base, and the telescopic ends thereof are fixedly connected to the bottom surface of the positioning platform.

[0009] As a preferred solution of the present invention, the No. 1 fastening plate is distributed symmetrically with respect to the top center axis of the positioning platform.

[0010] As a preferred solution of the present invention, the top thread of the support screw penetrates the bottom surface of the No. 1 fastening plate and is rotatably connected to the bottom surface of the lower support positioning block.

[0011] As a preferred solution of the present invention, the second fastening plate is arranged symmetrically front to back with respect to the top surface of the positioning platform.

[0012] As a preferred solution of the present invention, the output end of the low-speed motor passes through the bottom surface of the No. 2 fastening plate and is fixed to the bottom end of the rotating column, and the telescopic end of the hydraulic rod movably passes through the top surface of the mounting support plate and is fixedly contacted with the top of the upper support positioning block.

[0015] 1. In the utility model, a positioning fixture for an automobile frame is set up, thereby utilizing the structural design of a low-speed motor, a rotating column, a mounting support plate, a hydraulic rod, an upper support positioning block and a lower support positioning block. Driven by the low-speed motor, the mounting support plate drives the upper support positioning block to move above the frame. At the same time, driven by the hydraulic rod, the upper support positioning block is brought close to the frame, achieving a stable contact between the friction surfaces of the lower support positioning block and the upper support positioning block and the frame, thereby improving the positioning effect of the fixture on the frame, which is beneficial to subsequent welding operations.

[0029] In this embodiment, the positioning platform 1 is smoothly raised and lowered by the provision of the synchronous electric push rod 201 , thereby meeting the height adjustment requirement of the positioning platform 1 .

[0030] Specifically, the No. 1 fastening plate 5 is symmetrically distributed about the top central axis of the positioning platform 1, and the top thread of the support screw 502 passes through the bottom surface of the No. 1 fastening plate 5 and is rotatably connected to the bottom surface of the lower support positioning block 501;

[0031] In this embodiment, the driving turntable 503 is set to drive the support screw 502. Under the transmission cooperation between the support screw 502 and the No. 1 fastening plate 5, the height of the lower support positioning block 501 can be adjusted to adapt to the horizontal adjustment of different frames, thereby improving the adaptability of the tooling.

[0032] Specifically, the second fastening plate 6 is symmetrically arranged front to back with respect to the top surface of the positioning platform 1.
