The purpose of the utility model is realized with the following mode: the positioning main body is in a shape that one end of a cylinder occupies the excircle of most of the length of the positioning main body and is cut into a plane, the rest part of the cut plane circumferentially exceeds the half circumference, and the middle part of the plane is cut into a groove to form a step surface with two high ends and a low middle part; the positioning flat plate is fixed on the inner side high surface of the stepped surface through a fixing screw, the other end of the positioning flat plate is suspended on the middle low portion of the stepped surface and forms a gap with the middle low portion, a lower positioning plate is fixed on the outer side high surface of the stepped surface through a fixing screw, and the outer side surface of the lower positioning plate is slightly lower than the outer side surface of the positioning flat plate.
The end face of the end of the positioning main body, which is not tangent to the plane, is connected with a pull rod with a boss at the tail end through threads, and the rod part of the pull rod is sleeved with an impact ring which is a cylinder with a central hole. The impact ring impacts the pull rod to facilitate the pulling out of the positioning device.
The outer peripheral surface of the impact ring is provided with knurls, so that an operator can firmly hold the impact ring.
The size of the gap is 0.5mm-2mm, which meets the requirement of slight elastic deformation of the positioning flat plate.
The fixing screw adopts a countersunk screw, and the outer end part of the fixing screw for fixing the lower positioning plate is not higher than the outer side surface of the lower positioning plate, so that the influence on the loading and unloading of the workpiece is avoided.
The utility model discloses when using, pass the work piece locating plate portion down, press down the location flat board gently and embolia the work piece on the position that the location flat board was located, loosen the dull and stereotyped action of pressing down to the location, the dull and stereotyped lateral surface of location and the arc surface of location main part respectively with the tangent laminating of the arcwall face of work piece, the dull and stereotyped elastic action of location and the cooperation of location main part are with the work piece centre gripping, handheld location main part will be down locating plate that end insert fix a position in clamping device's locating hole, the work piece is pressed from both sides tight back by clamping device, handheld location main part or pull rod pull out positioner, if directly pull out the sensation when hard, can strike the pull rod with the impact ring, help the application of force is extracted work piece positioner.
The utility model can conveniently position the stator of the cycloid full hydraulic steering gear, eliminate the positioning clearance between the stator and the workpiece and improve the positioning precision; the workpiece is not easy to slide off during positioning operation, the use is convenient, and the time for positioning can be saved; the whole cost is low, and the popularization and the use are convenient.
