Problems solved by technology

[0003] The invention is aimed at sub-assembly welding of the passenger car underframe at a fixed position. After the assembly is welded, it is transferred to the fixed underframe tooling by driving and assembled again. The driving occupancy rate is high, the occupied area of ​​the site is large, the dimensional accuracy is low, and the production efficiency is low. In order to solve the problem, a flexible tooling that integrates welding, flipping, transfer and merging of sub-frames is invented.

Embodiment 1

[0059] like figure 1 As shown, the embodiment of the present invention provides a load-bearing bus chassis assembly welding, turning, transfer and assembly tooling, including a plurality of independent tooling, each independent tooling includes a channel steel welding frame 5, a channel steel The welding frame 5 is internally welded with a base surface 3, and the upper surface of the base surface 3 is detachably connected with a plurality of T-slot table tops 2 through bolts. Some T-slot table tops 2 are fixedly connected with positioning block 1 by bolts, and positioning block 1 is fixedly connected with T-slot table top 2 by bolts. The location is suitable for different vehicle types; the left and right sides of the base surface 3 are respectively fixed with a rope-type chassis turning device 12, which is used to realize the turning of the chassis.

[0060] Further, the base surface 3 is provided with a plurality of through holes for easy cleaning.

[0061]The number of in...

Embodiment 2

[0065] This embodiment is based on embodiment 1, as attached image 3 , attached Figure 4 As shown, the guide positioning mechanism includes a guide plate 61, the guide plate 61 is hinged with the left side of the channel steel welding frame 5 of the independent tooling through a rotating shaft, the guide plate 61 is a horizontal rotary guide plate 61, when not in use The guide plate 61 is horizontally rotated until the lower surface of the channel steel welded frame 5 is hidden, and it is horizontally rotated to as attached when in use. figure 1 The shown position cooperates with another adjacent independent tooling to play a guiding role; the top of the guide plate 61 is also provided with a positioning plate 62 for cooperating with it. The positioning plate 62 includes an arc segment and a straight arm segment, and the arc segment passes through the fifth arm. The rotating shaft is hinged on the side wall of the channel steel welded frame 5, and the straight arm section i...

Embodiment 3

[0070] This embodiment is based on Embodiment 1. The rope-type underframe turning device 8 includes a second base 81, a column 82, a hook 83 and a limiting element 84; the second base 81 is fixed on the channel steel welding frame 5 On the side, the upper end of the column 82 is fixed with a hook 83, and the lower end of the column 82 is hinged with the second base 81 through the fourth rotating shaft. And the column 82 is used to limit the rotation of the column 82 .

[0071] In the rope-type underframe overturning device 8 provided by the present invention, the fixing bolts are selected for the limiting element 84. When using the rope-type underframe overturning device 8, the upright column 82 is first rotated, and the upright column 82 will be used to fix the load-bearing type after it is rotated to a vertical position. One end of the rope of the passenger car chassis is fixed on the load-bearing bus chassis, and the other end is fixed on the hook 83. At this time, the thro...

Abstract

The invention provides a bearing type passenger car chassis assembling, welding, overturning, transferring and splicing integrated tool comprising a plurality of independent tools. Each independent tool comprises a channel steel welding frame, a base face is welded in each channel steel welding frame, and a plurality of T-shaped groove table tops detachably connected with the base face are arranged on the upper surface of each base face. A plurality of positioning blocks are detachably connected to each T-shaped groove table top. A rope type chassis turnover device for achieving turnover of a chassis is also fixed to the side face of each base face. A guiding and positioning mechanism used for guiding and positioning is arranged between every two adjacent independent tools, and meanwhile a tool clamping device used for splicing the two adjacent independent tools into one tool is further arranged between every two adjacent independent tools. By means of the bearing type passenger car chassis assembling, welding, overturning, transferring and splicing integrated tool, the use area is reduced, the production efficiency is improved, and the chassis block assembly welding, overturning repair welding, transferring and splicing are integrated.

Description

technical field [0001] The invention relates to the technical field of passenger car preparation tools, in particular to a tooling integrating welding, turning, transfer and assembling of a load-bearing bus chassis. Background technique [0002] The load-bearing bus chassis is an essential part of the bus manufacturing process, and plays a very important role in ensuring the size of the bus skirt and the flatness of the outer surface of the lower skirt. Among them, the problems of large site occupation, heavy workload, and low production efficiency are mainly concentrated in the sub-block welding of the load-bearing chassis, driving transfer and overall assembly stations. In the prior art, when the load-bearing chassis is assembled and welded, each part is placed on the ground in pieces for assembly and welding. After assembly and welding, the pieces are tailored and welded, turned over for repair welding, and transported to the corresponding station of the production line b...
