Description

Technical Field

[0001] The invention relates to the technical field of welding tooling, in particular to a main frame splicing device. Background Art

[0002] like Figure 3 As shown, the main frame is the main supporting component in the livestock equipment, which is mainly composed of an upper crossbeam 101, two connecting plates 102, four supporting beams 103, two connecting caps 104, two connecting legs 105 and a bottom frame 106. One end of the upper crossbeam is welded to the two connecting beams, and the other end is welded to the two connecting legs. The four supporting beams are divided into two groups and welded to the bottom of the upper crossbeam in a herringbone shape. The bottom of the four supporting beams is welded to the bottom frame. The bottom frame is bent downward on all sides and has a number of connecting holes. The two connecting caps are fixed to the bottom frame respectively. When welding the main frame, it is necessary to ensure the angle of the supporting beam and the position on the upper crossbeam and the bottom frame, the position of the two connecting legs and the two connecting plates on the upper crossbeam, and ensure that the through holes on the connecting plate, the connecting legs and the bottom frame correspond to the equipment during the final installation, so that the main frame as a whole can be assembled smoothly. Therefore, it is urgent to develop a splicing device so that the various components on the main frame can be accurately welded together. Summary of the invention

[0003] In order to effectively solve the problems in the above-mentioned background technology, the present invention proposes a main frame splicing device.

[0004] The specific technical solutions are as follows:

[0005] The support block is placed on the upper part of the left plate, and the support block is also provided with a through hole. The two positioning bolts cooperate with the through holes on the support plate and the support block. The left and right middle support plates are respectively fixed to the middle part of the bottom plate, and the upper parts of the left and right middle support plates are respectively provided with positioning grooves. The upper part of the right plate is provided with four positioning pins. The upper part of the left and right middle support plates is fixed with an upper positioning plate and a lower positioning plate from top to bottom on one side. The width of the front part of the upper positioning plate is smaller than the width of the front part of the lower positioning plate. The two positioning columns are respectively fixed to the bottom plate.

[0006] Preferably, strip grooves are provided on both sides of the bottom plate.

[0007] Preferably, triangular support plates are respectively provided on the sides of the left side plate, the right side plate, the left middle support plate and the right middle support plate.

[0008] Preferably, circular holes corresponding to those on the main frame are provided on both sides of the bottom plate.

[0009] Compared with the prior art, the beneficial effects of the present invention are: the structural design of the device is simple and reasonable, and the herringbone angle of the support beam can be guaranteed by two middle support plates and two upper and lower positioning plates on the upper part. The support block and the positioning pin can ensure the accurate positioning of the through holes on the connecting plate and the connecting leg, thereby improving the working environment, improving product quality, saving manpower and material resources, and reducing production costs.
