Problems solved by technology

Although the positioning of the groove system can be repeatedly positioned to any position, it cannot guarantee rigid positioning
That is to say, the existing fixture cannot achieve flexible positioning and rigid positioning at the same time.

Embodiment Construction

[0025] figure 1 Among them, the left-right direction of the base 10 is the horizontal direction, and the front-rear direction of the base 10 is the vertical direction. The limiting plate extends along the front and back direction of the base 10 , and in the plane where the limiting plate is located, the length direction of the limiting plate is defined as longitudinal direction, and the width direction of the limiting plate is defined as transverse direction.

[0026] Please refer to Figure 1 to Figure 4 , a flexible fixture for welding the pedal frame of a passenger car, including a base 10 and four limiting plates longitudinally arranged above the base, the four limiting plates are arranged in a W shape from left to right at intervals and defined as limiting plates in order 20-1, limit plate two 20-2, limit plate three 20-3, limit plate four 20-4. The left side of the top of the base 10 is provided with an L-shaped bracket 30 , and the included angle of the bracket 30 is ...

Abstract

The invention discloses a flexible clamp for passenger car pedal skeleton welding. The flexible clamp comprises a base and four limiting plates longitudinally arranged above the base, wherein the limiting plates are connected by a hinge mechanism; a positioning block and a clamping block which can transversely slide are arranged on the top surface of each limiting plate, and sliding grooves corresponding to the positioning block and the clamping block are respectively formed in each limiting plate; the positioning block and the clamping block are locked on the corresponding limiting plate respectively through bolt components; and the positioning block and the clamping block are mutually matched to clamp a longitudinal rod of a skeleton. According to a series of structural differences of the passenger car pedal skeleton, the welding clamp is regulated to a designated position precisely and quickly to carry out corresponding clamping and fixation, thus the adjustment of several degrees of freedom in a plane and space is realized, the application scope and flexibility of the fixture tool are improved, the manufacturing cost is reduced, and the manufacturing time is shortened. The clamping block and the positioning block are fixed through the bolt components, so that the rigid positioning is ensured, and the positioning precision and the clamping function can also be ensured.

Description

technical field [0001] The invention relates to a welding fixture, in particular to a flexible fixture for welding a passenger car pedal frame. Background technique [0002] At present, in the field of bus body frame welding, the flexibility of tooling is generally not high. Most of the welding production adopts the mode of one fixture corresponding to one welding product, and the versatility of fixtures is low. However, the speed of updating and changing passenger car products is fast, and the demand for products varies. In order to complete the welding work of a series of products, it is necessary to produce a series of corresponding welding fixtures. This kind of welding production mode not only has high manufacturing cost, but also the production of various welding fixtures prolongs the production cycle and occupies production space. In most cases, the structure of the passenger car pedal frame is similar. Therefore, inventing a flexible fixture for welding the pedal ...
