Abstract

The utility model discloses a pin remover belonging to the technical field of detaching tools pf positioning pins and comprising upright post anchors, rotating upright posts, a cross bridge and a clamp with a bolt, wherein two rotating upright posts are in respective threaded connection with two upright post anchors corresponding to the two rotating upright posts; the middle of the cross bridge is provided with a square hole; two ends of the cross bridge are provided with round holes; the two rotating upright posts respectively pass through the round holes at two ends of the cross bridge and connected with the cross bridge by riveting; the cross bridge and the two rotating upright posts can freely rotate; a bolt connected with an inner threaded hole of a positioning pin is welded at the lower part of the clamp with the bolt; a cuboid corresponding to a rectangular hole in the middle of the cross bridge is arranged at the upper part of the clamp with the bolt and passes through the rectangular hole in the middle of the cross bridge; and the clamp with the bolt is clamped on the cross bridge after rotating by 90 degrees. The pin remover has simple structure and convenient use, and can remove the positioning pin in a narrow space can be removed by the pin remover. The clamp with the bolt is matched with bolts with different sizes, thereby the utility model can realize the removing function of the positioning pin with inner threads and different specifications.

Description

A kind of pin removal

Technical field

The utility model relates to a kind of pin removal, belongs to the technical field of alignment pin extracting tool.

Background technology

The application of alignment pin in the equipment of industrial product is very extensive, is generally used for requiring repetitive positioning accuracy than under the higher situation, plays the positioning and directing effect.When carrying out overhaul of the equipments, alignment pin need be disassembled, to make things convenient for the inspection and maintenance of parts.ZL200720110752.9 discloses a kind of pin removal, during the dismounting rationed marketing, need hold the sliding upwards cylinder end face of hammering pin removal bar of hammering into shape firmly, is applicable to the occasion that the alignment pin location in space is openr, can dismantle the internal thread alignment pin fast and reliablely.If but alignment pin locus of living in is narrower and small, use existing paddle type mill pin removal then can't extract alignment pin, therefore, in actual production, need to extract the pin removal of alignment pin at small space.

Summary of the invention

The purpose of this utility model is exactly that a kind of pin removal that can extract alignment pin at small space will be provided.

For achieving the above object, the pin removal of the utility model design comprises the column lower margin, Rotary cloumn, cross-bridges and strap bolt jig, described Rotary cloumn is two, respectively with corresponding two root post lower margins by being threaded, open oblong aperture in the middle of the described cross-bridges, circular hole is opened at two ends, two Rotary cloumns pass the circular hole at two ends respectively, be connected with cross-bridges by rivet, free to rotate between cross-bridges and two Rotary cloumns, the bolt that the welding of described strap bolt jig bottom is connected with the alignment pin internal thread hole, top is and the middle corresponding cuboid of oblong aperture of cross-bridges, cuboid passes the oblong aperture in the middle of the cross-bridges, and behind the half-twist, the strap bolt jig is stuck on the cross-bridges by cuboid relatively.

Advantage of the present utility model is: simple in structure, easy to use, the alignment pin that is in small space can be extracted, and the strap bolt jig is joined the bolt of different size, can realize the function of extracting of different size internal thread alignment pin.

Description of drawings

Fig. 1 is the front view of the utility model pin removal;

Fig. 2 is the vertical view of the utility model pin removal;

Fig. 3 is the structure chart of strap bolt jig.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Figure 1 shows that the pin removal front view.As shown in Figure 1, pin removal is made up of column lower margin 1, Rotary cloumn 2, cross-bridges 3 and strap bolt jig 4, described Rotary cloumn 2 is two, internal thread hole is arranged at the bottom, externally threaded column lower margin 1 is arranged by being threaded with two respectively, opens oblong aperture A in the middle of the described cross-bridges 3, there is circular hole at two ends, penetrate Rotary cloumn 2 respectively, by rivet 5 with described cross-bridges 3 riveted and fixed between two Rotary cloumns 2, free to rotate between cross-bridges 3 and two Rotary cloumns 2; The bolt 6 that the bottom welding of described strap bolt jig 4 is connected with the alignment pin internal thread hole, top be with cross-bridges 3 in the middle of the corresponding cuboid B of oblong aperture A, cuboid B passes the oblong aperture A in the middle of the cross-bridges 3, relatively behind the half-twist, cuboid B is stuck on the cross-bridges 3, and the vertical view of assembling back pin removal is seen Fig. 2.

During use, bolt 6 with strap bolt jig 4 screws in the alignment pin internal thread hole earlier, then the oblong aperture A of the column lower margin 1, Rotary cloumn 2 and cross-bridges 3 assemblies that assemble was overlapped the top cuboid B of strap bolt jig 4, and, strap bolt jig 4 is stuck on the assembly by cuboid B with the assembly half-twist.Keep column lower margin 1 motionless, rotate two Rotary cloumns 2 simultaneously, drive cross-bridges 3 and raise, cross-bridges 3 drives strap bolt jig 4 and rises, and alignment pin is extracted thereupon.

Burn-on the respectively full silk bolt 6 of different sizes such as M8, M10, M12, M14, M16 of strap bolt jig 4 bottoms can be extracted the internal thread alignment pin of corresponding specification.

For the convenient Rotary cloumn 2 that rotates, Rotary cloumn 2 is designed to outer hexagon column.
