Description
Technical Field
[0001] The utility model relates to a positioning tool for assembling and assembling a 6-meter or 7-meter frame, and belongs to the technical field of passenger car processing equipment. Background Art
[0002] The existing bus frame assembly welding process lacks special positioning tooling. Welding positioning requires manual measurement of values in the X, Y, and Z directions. The operation is not standardized and it is difficult to ensure accuracy, resulting in large variations in welding accuracy, high labor costs, and low work efficiency. Utility Model Content
[0003] The technical problem to be solved by the present invention is to provide a positioning tool for assembling and assembling a 6-meter or 7-meter frame, so as to solve the technical problems existing in the above-mentioned prior art.
[0004] The technical solution adopted by the utility model is as follows: the 6-meter and 7-meter frame assembly positioning tooling includes a chassis, which is in the shape of a rectangular frame; the upper end of the chassis is provided with a front overhang positioning tooling and a rear overhang positioning tooling, the front overhang positioning tooling includes a front overhang positioning tooling bottom plate, and two front overhang positioning columns are provided on the front overhang positioning tooling bottom plate; the rear overhang positioning tooling includes a rear overhang positioning tooling bottom plate, and two second rear overhang positioning columns are provided on the rear overhang positioning tooling bottom plate; a rear overhang positioning tooling bottom plate is provided on the side of the second rear overhang positioning column away from the front overhang positioning column Two first rear suspension positioning columns; two first rear suspension auxiliary positioning columns are fixed on the end of the base frame away from the front suspension positioning column; two second rear suspension auxiliary positioning columns are provided on the part of the base frame located between the first rear suspension auxiliary positioning column and the rear suspension positioning tooling bottom plate; the front suspension positioning column, the second rear suspension positioning column and the second rear suspension auxiliary positioning column are used together for positioning the 6-meter frame splicing assembly; the front suspension positioning column, the first rear suspension positioning column, the second rear suspension positioning column and the first rear suspension auxiliary positioning column are used together for positioning the 7-meter frame splicing assembly.
[0005] Preferably, a circular support plate arranged in a horizontal direction is fixed to the upper end of the front suspension positioning column.
[0006] Preferably, a circular support plate arranged in a horizontal direction is fixed to the upper end of the second rear overhang positioning column.
[0007] Preferably, chassis pads are fixed at the four corners of the lower end of the chassis.
[0008] Preferably, the shape of the front overhang positioning tool corresponds to the front overhang part of the bus assembly.
[0009] Preferably, the shape of the rear suspension positioning tool corresponds to the rear suspension part of the bus assembly.
[0010] The beneficial effects of the present invention are as follows: compared with the prior art, the present invention designs a special positioning tool for the welding positioning of the bus frame assembly, and can simultaneously match 6-meter and 7-meter models, achieving commonality between different models; welding positioning does not require manual measurement of the values in the X, Y, and Z directions, thereby reducing labor costs, standardizing operations, and achieving high accuracy, thereby improving product standard consistency and work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a three-dimensional diagram of the overall structure of the utility model.
[0012] The figure marks in the drawings of the specification include: chassis pad 10, chassis 20, rear overhang positioning tooling base plate 30, first rear overhang positioning column 31, second rear overhang positioning column 32, first rear overhang auxiliary positioning column 33, second rear overhang auxiliary positioning column 34, front overhang positioning tooling base plate 40, front overhang positioning column 41. DETAILED DESCRIPTION
[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0014] Example 1:
[0015] 6m and 7m frame assembly positioning tooling, such as Figure 1 As shown, it includes a chassis 20, which is a rectangular frame. The four corners of the lower end of the chassis 20 are fixed with chassis pads 10. The upper right end and the upper left end of the chassis 20 are respectively provided with front overhang positioning tooling and rear overhang positioning tooling. The shape of the front overhang positioning tooling corresponds to the front overhang part of the bus assembly. The front overhang positioning tooling includes a front overhang positioning tooling base plate 40. Two front overhang positioning columns 41 are provided on the front overhang positioning tooling base plate 40. The two front overhang positioning columns 41 are symmetrically arranged front and back. The upper end of the front overhang positioning column 41 is fixed with a circular support plate arranged in the horizontal direction for supporting the front overhang part of the bus assembly.
