Embodiment 1

[0029] Embodiment 1 (floor assembly and welding)

[0030] Such as Image 6 As shown, first, according to the length of the floor, increase the number of tooling units in the longitudinal direction of the floor. After the longitudinal number is determined, then adjust the column 2 of each tooling unit as follows according to the requirements of the operating height and the height of the workers. By controlling the hydraulic cylinder Ⅰ22 Adjust the inner column 23 to expand and contract relative to the outer column 21, so as to drive the beam 3 to a suitable height, only fix the end positioning beam 5 on the beam 3 of the tooling unit at the head end position, and install the end positioning beam 5 on the end positioning beam 5 Module 6. Secondly, place the side positioning module 1 on one end of the beam 3 of all tooling units, the support nail 43 is placed on the beam 3 through the sleeve 42, the plane type is selected for the support head 41, and the horizontal number of the...

Embodiment 2

[0031] Embodiment 2 (middle roof assembly and welding)

[0032]Firstly, increase the number of vertical tooling units on the floor according to the length requirements of the middle roof. After the vertical number is determined, the column 2 of each tooling unit is adjusted as follows according to the requirements of the operating height and the height of the workers. Adjustment is made by controlling the hydraulic cylinder I22 The inner column 23 is stretched relative to the outer column 21, thereby driving the beam 3 to a suitable height, only fixing the end positioning beam 5 on the beam 3 of the tooling unit at the head end position, and installing the end positioning module 6 on the end positioning beam 5 . Secondly, place the side positioning module 1 on one end of the crossbeam 3 of all tooling units, the support nail 43 is placed on the crossbeam 3 through the sleeve 42, the support head 41 selects the curved surface type, and adjusts the horizontal position of the sup...

Abstract

The invention discloses a flexible tool system for assembling and welding a floor and a middle roof plate of an urban rail car. The flexible tool system is allocated by arranging a plurality of tool units according to needs, and comprises a foundation framework, bearing structures, a positioning structure and a clamping structure; the foundation framework is formed by a transverse beam and stand columns arranged at the two ends of the transverse beam; the bearing structures are arranged on the transverse beam through sleeves by means of bearing nails at intervals, and a bearing head is arranged at the top end of each sleeve; the positioning structure is a side positioning module arranged at one end of the transverse beam, when the tool units are arranged at the head end position or the tail end position, the positioning structure further comprises an end positioning transverse beam arranged on one side face of the transverse beam, and the end positioning transverse beam is provided with height-adjustable end positioning modules at intervals; and the clamping structure achieves positioned clamping through a fixed clamp arranged at the end, provided with the side positioning module, of the transverse beam and a movable clamp arranged at the other end of the transverse beam and connected with a movement structure. The flexible tool system is reasonable in structural design, the fatigue strength of workers is effectively relieved, the installation accuracy is improved, the installation schedule is accelerated, the working efficiency is effectively improved, rapid clamping is achieved, and the aim of lean production is achieved.

Description

technical field [0001] The invention relates to the technical field of urban rail car assembly welding equipment, in particular to a flexible tooling system suitable for urban rail vehicle floor and middle roof assembly welding. Background technique [0002] The present invention is a flexible process equipment for floor and middle roof assembly welding of urban rail vehicles. When performing floor and middle roof assembly welding, it is first necessary to design corresponding process equipment according to different vehicle types. At present, each time a vehicle type is replaced, it needs to be redesigned. Manufacture a set of corresponding tooling equipment and replace different fixtures according to different parts, which not only prolongs the product development cycle, increases manufacturing costs, but also weakens the market competitiveness of enterprises. In addition, in the process of floor and roof assembly welding, in order to meet the needs of floor and roof assem...
