The utility model is realized by following technical scheme:
A kind of bull-dozer fan protection frame welding equipment positioning compression device, comprise clamp body, hold down gag and a left side, right support, rotating shaft is all equipped with at the two ends, left and right of clamp body, rotating shaft installs to respectively a left side, in axle sleeve on right support, clamp body is the frame structure being formed by rectangular tube assembly welding, before and after clamp body, both sides are welded with strip plate, alignment pin for positioned soil shifter fan protection frame upper plate and position, backing plate hole is housed on strip plate, positioning core axle for plectane in the middle of locating is housed in the middle of clamp body, positioning core axle border is distributed with the two-layer U-shaped locating piece that is used for orientation assemble support plate from inner outside clamp body, clamp body outer ring is evenly distributed with the multiple hold down gags for fast-holding bull-dozer fan protection frame, in the middle of clamp body, be provided with for plectane in the middle of compressing and symmetrical hold down gag.
Two alignment pins are housed on each strip plate, and one is diamond positioning pin, and one is cylindrical positioning pins.
Hold down gag comprises mount pad, cantilever and paw, and cantilever is arranged on mount pad and the upper and lower flip vertical of mount pad relatively, and paw is arranged on one end away from mount pad on cantilever, on paw, is threaded, and coordinates installation with the screw on cantilever.
The utility model can fast-holding workpiece, and by alignment pin location, accurate positioning, adopts that overturn structure welding is disposable completes whole weld seams, ensures every technical requirement, has greatly improved production efficiency.

Detailed description of the invention
As shown in Fig. 1-8; bull-dozer fan protection frame is that multiple support plates 4 assembly weldings of the base plate with semi arch (left bottom plate 1 and right base plate 5), two backing plates 2, middle plectane 3 and connecting bottom boards (1,5) and middle plectane 3 form by two; two backing plates 2 are connected with two base plates from both sides, the hole that backing plate 2 is corresponding with having position on base plate.Wherein, on each backing plate, there are two locating holes.After welding, require position, each hole accurate, support plate 4 is evenly distributed, and base plate plane is smooth.
Bull-dozer fan protection frame welding equipment positioning compression device of the present utility model, comprise clamp body 6, hold down gag 11 and be positioned at clamp body 6 left sides, the support 12 at right two ends, rotating shaft 13 is all equipped with at the two ends, left and right of clamp body 6, rotating shaft 13 installs to respectively a left side, in axle sleeve on right support 12, the frame structure of clamp body 6 for being formed by rectangular tube assembly welding, both sides, front and back are welded with strip plate, on strip plate, be equipped with two and be used for positioned soil shifter fan protection frame upper plate (1, 5) with the alignment pin (diamond positioning pin 7 and cylindrical positioning pins 8) of backing plate 2 positions, hole, alignment pin coordinates with the locating hole on bull-dozer fan protection frame realizes location.Positioning core axle 9 for plectane 3 in the middle of locating is housed in the middle of clamp body 6; positioning core axle 9 borders are distributed with the two-layer U-shaped locating piece 10 that is used for orientation assemble support plate 4 from inner outside clamp body; clamp body 6 outer rings are evenly distributed with the multiple hold down gags 11 for fast-holding bull-dozer fan protection frame, in the middle of clamp body 6, are provided with for plectane 3 in the middle of compressing and symmetrical hold down gag 11.
