Embodiment 1

[0039] The combined tooling of this embodiment includes a bracket 10 and a positioning tool 12, the bracket 10 is placed below the longitudinal beam 9 of the semi-trailer frame, and the positioning tool 12 is placed above the longitudinal beam 9 of the semi-trailer frame.

[0040] Bracket 10 includes two connecting rods 1, 7 sets of vertical support rods 2 with different heights and 7 groups of horizontal cross bars 4 with different heights. Connected, the vertical support bar 2 and the horizontal cross bar 4 form a "Π" shape structure and fit together with the upper end surface of the longitudinal beam of the vehicle frame; the positioning blocks 3 for the positioning of the vehicle frame longitudinal beam are installed at both ends of the horizontal cross bar 4.

[0041] In order to facilitate processing and manufacturing, the vertical struts 2 of this embodiment are integrated with the connecting rods 1 and the horizontal bars 4 by welding. The connecting rod 1 is made of a...

Abstract

The invention discloses a frame combination tooling of a semitrailer and a manufacturing method thereof, which are used for solving the problems of fussy positioning, low accuracy and easy error in the frame combination process of the existing semitrailer. The frame combination tooling comprises a supporting frame and a positioning tooling, wherein the supporting frame is arranged below a longitudinal beam of a frame of the semitrailer; and the positioning tooling is arranged above the longitudinal beam of the frame of the semitrailer. The frame combination tooling disclosed by the invention has the beneficial effects that the parallel clamping and fixing of the longitudinal beam of the frame is ensured by utilizing the supporting frame, and simultaneously, consistent spacing among cross beams of the combined frame at the later stage is also ensured; and mutual position relation and parameters of a traction pin, the cross beams of the frame and a hanging bracket are ensured by utilizing the positioning tooling. The frame combination tooling disclosed by the invention has the characteristics of simple structure, convenience in positioning and high accuracy.

Description

technical field [0001] The invention belongs to the field of tooling, and in particular relates to a semi-trailer frame assembly tooling and a manufacturing method thereof. Background technique [0002] A semi-trailer is a trailer whose axle is placed behind the center of gravity of the vehicle and is equipped with a hitch that transmits horizontal or vertical forces to the tractor. Semi-trailers mainly transport bulky goods that are not easily disassembled. Compared with "single-body" cars, semi-trailers can improve the comprehensive economic benefits of road transportation. The transportation efficiency can be increased by 30-50%, the cost can be reduced by 30-40%, and the fuel consumption can be reduced by 20-30%. Semi-trailers play a pivotal role in industry and have made outstanding contributions to promoting the development of industry and economy. [0003] However, the positioning of the existing semi-trailer frame is tedious during the assembly process, and the acc...
