Problems solved by technology

[0004] like figure 1 As shown, it is a fixture with a two-stage rotary arm structure, that is, a rotary arm mechanism 23 driven by two driving cylinders to realize process control in the vertical and horizontal directions, so as to realize the rotation of the rotary arm. The radius of the rotary arm is Large, affected by air pressure fluctuations, the rotating mechanism will shake, and even cause the parts to fall off in severe cases, resulting in damage to the parts, and there is a hidden danger of accidental injury to the operator; Influence, the fixture limit block is easy to wear and loosen, resulting in the decrease of fixture precision and poor stability
[0005] like figure 2 As shown, the clamp adopts the spreader mechanism, and the spreader mechanism 24 powered by the air hoist can move up and down. The lock and movement efficiency are low, which cannot meet the production requirements of high capacity and fast pace
[0006] Moreover, the front floor positioning and clamping devices of the above two fixtures cannot meet the requirements of automatic production when the front floor is fed and discharged.
[0007] Therefore, the traditional welding fixture with rotating arm structure and spreader structure can no longer meet the welding process requirements of the front floor and front seat mounting crossbeam of the car. As the vehicle manufacturing level is becoming more and more mature, the development and matching The welding fixture tooling is imminent

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Such as Figure 3~Figure 5 As shown, the clamp used for welding the front floor of the automobile and the front seat installation beam according to the present invention includes a clamp base 10, a front floor positioning clamping device and a front seat installation beam positioning clamp located on the clamp base. device.

[0028] The front row seat mounting crossbeam positioning and clamping device includes four uprights 7, which are equally divided into two groups, one group is fixed on the left middle part of the clamp base, and the other group is fixed on the right side middle part of the clamp base. The tops of the two columns are fixed together by a connecting plate. It also includes a fixed beam 2 connecting the top of the column. The fixed beams are also two, parallel and juxtaposed, connected to the top of the column through the connecting plate, an...

Abstract

The invention relates to a fixture used for welding of an automobile front floor and a front row seat installation crossbeam. The fixture comprises a front floor positioning clamping device and a front row seat installation crossbeam positioning clamping device, wherein the front floor positioning clamping device and the front row seat installation crossbeam positioning clamping device are arranged on a fixture base. The front row seat installation crossbeam positioning clamping device comprises four upright columns divided into two groups, fixing beams connecting the top ends of the two groups of upright columns and a gantry framework structure formed by the upright columns and the fixing beams. A sliding beam is arranged under the fixing beams, the two ends of the sliding beam are connected with the upright columns in a sliding mode, and the middles of the fixing beams are provided with a self-locking cylinder, and the head of a piston rod of the self-locking cylinder is downward and is fixedly connected with the middle of the sliding beam. The upright columns are provided with limiting blocks, the sliding beam is provided with a cantilever moving in the front-back direction, clamping components are arranged on the cantilever, and positioning pins are disposed on the clamping components. The fixture can precisely position the front row seat installation crossbeam longitudinally and horizontally, the front row seat installation crossbeam does not shake during positioning, stability is good, and safety hidden hazards caused by shaking are avoided.

Description

technical field [0001] The invention belongs to the technical field of automobile production tooling, and in particular relates to a fixture used for welding the front floor of the automobile and the crossbeam for installing front seats. Background technique [0002] With the rapid development of the automobile industry, various OEMs have higher and higher requirements for body precision, and more and more attention has been paid to ergonomics, which has prompted continuous innovation and change in the functional structure and operability of welding fixtures to meet High standards of quality control requirements and comfortable operability requirements. [0003] The installation of the front seat of the car requires high precision to meet the comfort of the ride. The front seats of the car are usually fixed on the front seat installation beam, and the front seat installation beam needs to be welded on the front floor of the car. Therefore, the welding quality and welding qu...
