Embodiment Construction

[0016] The embodiment of the welded mold in the middle section of the frame of the full-loaded passenger car: as Figure 1 to Figure 4 As shown, the welding tire is mainly composed of the underframe 2, the longitudinal beam positioning device 4 for positioning the frame 1 longitudinal beam 12 and the brace 13, and the beam positioning device 3 for positioning the vehicle frame 1 beam 11.

[0017] Wherein, two guide rails 21 are arranged on the underframe 2, and there are eight longitudinal beam positioning devices 4 and are all perpendicular to the guide rails 21. The main body of the longitudinal beam positioning device is composed of a bracket 41, and the bottom of the bracket 41 is provided with a Along the lengthwise direction of the guide rail 21 is a sliding block 42 that is guided and matched. A pneumatic finger 43 for locking the longitudinal beam positioning device on the chassis 2 is arranged between the two sliding blocks 42, and the chassis 2 is positioned on the lo...

Abstract

The invention relates to a welding clamping fixture for a midpiece of a monocoque bus frame. The welding clamping fixture comprises an underframe on which two guide rails are arranged in parallel, wherein at least two longitudinal beam positioning devices perpendicular to the guide rails are arranged on the guide rails, each longitudinal beam positioning device comprises a bracket, slider blocks which are matched with the guide rails in a guiding manner along the length direction of the guide rails are arranged at the bottoms of the brackets, a longitudinal beam clamping seat is arranged at the top of each bracket, and a diagonal-bracing clamping seat is arranged between the two longitudinal beam clamping seats; and traverse beam positioning devices are arranged at outer sides of the both ends of each longitudinal beam positioning device on the underframe, and each traverse beam positioning device comprises an adapting pole on which a traverse beam clamping seat is arranged. When the welding clamping fixture is in use, the longitudinal beam positioning devices can be used for positioning the longitudinal beams and the diagonal bracings of the bus frame, and the traverse beam positioning devices are used for positioning the traverse beams of the bus frame, the longitudinal beam positioning devices can be regulated according to different spacing distances among the traverse beams of the bus frame, and the traverse beam positioning devices can be replaced according to different bus frame structures, therefore, the welding clamping fixture can satisfy the welding requirements of bus frames of various structures through simple regulation.

Description

technical field [0001] The invention relates to a welding mold for a vehicle frame in mechanical manufacturing, in particular to a welding mold for the middle section of a vehicle frame of a full-loaded passenger car. Background technique [0002] Passenger cars generally adopt small batches and various types of customized production, especially the production mode of full-carrying buses. However, buses of the same length in the same order often have different types of frame structures, and the lead time required by customers is generally relatively short. short. [0003] The frames of full-loaded passenger cars are mostly welded square tubes. When designing models, the conversion of models is realized by changing the length of the frame, and the change of frame length is mainly realized by lengthening (or shortening) the middle section of the frame. , which has just caused the problem that the middle sections of different types of vehicle frames need to be produced in a re...
