Embodiment 1

[0024] see Figure 1-Figure 4 , in the figure, the fixture used for welding the base of logistics vehicles in the present invention includes a bottom plate 1, on which a plurality of limit posts are symmetrically arranged on the bottom plate, along the outer sides of the three side surfaces of the base frame 13 and the side plates of the left and right caster plates 14 2. There is a limit block 3 on the base plate and below the base crosspiece 15, an avoidance hole 4 is set on the base plate, corresponding to the extension of the rear end of the left and right caster plates, and left and right pressure blocks are respectively set in the left and right wheel forks 16 5, 6, the left and right pressure blocks are fixed on the bottom plate through the middle connecting plate 7, and the two sides of the middle connecting plate are provided with retreat grooves 8 for avoiding the two sides of the outer frame of the base. The bottom of the plate and the bottom plate are respectively ...

Embodiment 2

[0027] see Figure 5 , the structure of this embodiment is similar to that of Embodiment 1, and the same structural parts will not be repeated here. The screws are fixedly connected. At this time, the bottom plate is provided with via holes, and the bottoms of the limit post, the limit block and the intermediate connecting plate are provided with internal thread holes 11 matching the external threads of the screws.

[0028] Compared with Embodiment 1, the bottom of the limiting post, the limiting block, and the intermediate connecting plate and the bottom plate of this embodiment are respectively fixed and connected by screws, which can be disassembled and assembled quickly, making it more convenient to use. In addition, the structural form is changed, and more embodiments are added, which is beneficial to popularization and implementation.

Embodiment 3

[0030] see Image 6 , the structure of this embodiment is similar to that of Embodiment 1, and the same structural parts will not be repeated here. The difference is that: the bottom of the limiting column described in this embodiment is provided with a cylindrical boss 12, and the surface of the boss is provided with an external thread , the bottom plate is correspondingly provided with threaded holes, and the limit post is screwed to the bottom plate through the boss.

[0031] Compared with Embodiment 1, the bottom of the limiting column in this embodiment is provided with a cylindrical boss, and the limiting column is screwed to the bottom plate through the boss, which can be disassembled and assembled quickly, making it more convenient to use. In addition, the structural form is changed, and more embodiments are added, which is beneficial to popularization and implementation.

Abstract

The invention relates to a welding tooling, in particular to a clamp for welding a logistics automobile base. The clamp comprises a bottom plate, wherein a plurality of limiting columns are symmetrically arranged on the bottom plate, along the outer sides of the three side surfaces of a base outer framework, and on the outer sides of side plates of a right castor plate and a left castor plate, limiting blocks are respectively arranged on the bottom plate and under a base transverse rod, the extending parts of the back ends, corresponding to the left castor plate and the right castor plate, of the bottom plate are respectively provided with an avoiding hole, the interiors of a left wheel fork and a right wheel fork are respectively provided with a left press block and a right press block, the left press block and the right press block are fixedly arranged on the bottom plate by a middle connecting plate, the two sides of the middle connecting plate are respectively provided with a recession groove for avoiding the two sides of the base outer framework, and the bottom parts of the limiting columns, the limiting blocks and the middle connecting plate are fixedly connected with the bottom plate. The clamp has the advantages that the structure design is reasonable, the quick clamping and positioning are realized, the contour of a product can be completely welded at one time, the produced product has little error and stable quality and structure, the labor strength of workers is reduced, the production efficiency is greatly improved, the production cost is low, and the clamp is suitable for being popularized and implemented.

Description

technical field [0001] The invention relates to a welding tool, in particular to a fixture for welding the base of a logistics vehicle. Background technique [0002] In the production and processing process of the current logistics vehicle base, multiple processed parts are welded together one by one. After welding, the processing error is large, the size is difficult to guarantee, and the processing time is long and the work efficiency is low. In order to facilitate welding, improve welding efficiency, and ensure welding quality, the base of the logistics vehicle is initially considered to be divided into six parts, namely, the outer frame of the base, the crosspiece of the base, the left and right wheel forks, and the left and right caster plates. The interior of each part is initially welded. After that, welding between the parts is carried out. Therefore, it is necessary to design a special welding fixture for welding between the parts of the logistics vehicle base, so ...
