[0014] Attached Figure 2 It is a schematic diagram of the overall structure of the frame side tube and side beam positioning device. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings.

[0016] As attached Figure 1 As shown, the side beam 3 is composed of a tube body 31, a horizontal plate 32 and a vertical plate 33. The front and rear ends of the tube body 31 are connected to the side tubes, and the vertical plates 33 are connected to the side tubes. Figure 2 As shown, the side tube and side beam positioning device of the vehicle frame includes a positioning plate 1, on which a side beam support portion 2 is provided, and the side beam 3 is supported by the side beam support portion 2 to be in a horizontal position; on the positioning plate 1, a tube pushing positioning mechanism 4 is provided corresponding to the tube body 31 of the side beam 3, and a plate pushing mechanism 5 is provided corresponding to the cross plate 32 of the side beam 3. The side beam 3 is positioned on the positioning plate 1 through the cooperation of the tube end pushing of the tube pushing positioning mechanism 4 and the plate body pushing of the plate pushing mechanism 5. The utility model positions the side beam 3 by performing tube body end positioning and cross plate pressure positioning. In the two positioning force directions, the end positioning and pressure positioning directions intersect, which is different from the existing vertical pressure positioning technology, and can better position the side beam 3, greatly improving the positioning stability of the side beam.

[0017] As attached Figure 2As shown, the side beam support portion 2 includes a tube support portion 21 and a vertical plate support portion 22. The tube 31 of the side beam 3 is supported by the tube support portion 21, and the vertical plate 33 of the side beam 3 is supported in a horizontal posture by the vertical plate support portion 22. The tube support portion 21 and the vertical plate support portion 22 are both support blocks installed on the positioning plate 1, wherein the top surface of the tube support portion 21 is provided with a groove adapted to the outer circumference size of the tube 31, and the top surface of the vertical plate support portion 22 is a planar structure.

[0018] The end push positioning mechanism 4 includes an oblique blocking column 41 located at the front end of the tube body 31 of the side beam 3 and an end push block 42 located at the rear end of the tube body 31. The end push block 42 pushes toward the tube body 31 and cooperates with the oblique blocking column 41 to clamp and position the tube body 31, thereby limiting the displacement of the tube body 31 in the tube length direction and achieving stable positioning. Since the front end of the tube body 31 is an oblique concave structure, the oblique blocking column 41 is used to block and limit the front end of the tube body 31, and the limiting fit is better. In addition, the rear end of the tube body 31 is a flat concave structure, and the push surface of the corresponding end push block 42 must be adapted to the flat concave structure and set to a convex structure to ensure the tightness of the clamping positioning fit.

[0019] The utility model includes an end push driving part 43 corresponding to the push block 42, and the end push driving part 43 provides a driving force for the push block 42 to perform feed push. The end push driving part 43 can be selected to be automatic push and manual push. When automatic push is selected, it is best to use an easily controllable cylinder.

[0020] As attached Figure 2 As shown, the plate pushing mechanism 5 includes a plurality of plate pushing blocks 51 connected to the same moving beam 7, and the plate pushing blocks 51 push the positioning device in a one-to-one correspondence with the transverse plate 32 of the side beam 3. It includes a plate pushing driving part 52 that provides a feeding pushing driving force corresponding to the plate pushing blocks 51 and a guide rail 53 that provides a guide, and the moving beam 7 is located on the guide rail 53, and the pushing end of the plate pushing driving part 52 is connected to the moving beam 7. There is a slider on the guide rail 53, and the moving beam 7 is connected to the slider. The plate pushing driving part 52 is preferably a cylinder.

[0021] The top of the plate pushing block 51 is provided with a limiting top protrusion 510 for vertically limiting the horizontal plate 32 pushed by it. The limiting top protrusion 510 exceeds the pushing surface of the plate pushing block 51 in the structural extension direction, and an L-shaped structure is formed between the limiting top protrusion 510 and the plate pushing block 51.

[0022] The vertical plate support portion 22 is provided with a vertical axis pin 8 inserted through the vertical plate 33 to achieve horizontal limiting, and the plate pushing block 51 is provided with a transverse axis pin 9 inserted through the transverse plate 32 to achieve vertical limiting, which has a pin hole matching positioning.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
