Description
Technical field
The utility model relates to the correction positioner of thick right boring piston pin hole center line and outer face perpendicularity, is applied to be installed in the vertical situation of establishing on thick, the right boring piston pin hole fixture between bore hole center line and the outer face.
Background technology
Along with the development of automobile industry, the requirement of the assembly performance of each parts of engine is also improved constantly.In order to improve the piston assembly performance, people begin to pay close attention to the perpendicularity between piston pin hole outer face and the pin-and-hole center line.
The location of correcting tool is the orientation of proofreading and correct the pin-and-hole black skin with the manual mode that promotes adjustable stem in the existing heavy boring pin-and-hole operation; This correcting mode has two direction defectives to guaranteeing the perpendicularity between piston pin hole outer face and the pin-and-hole center line: the one, and the manual adjustable stem thrust instability that promotes; Pressing plate presses down the moment of piston, and piston position squints easily.The 2nd, the circularity of piston blank pin-and-hole mouth is lost circle.Thereby the piston percent defective behind the bore hole is high.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned weak point of the prior art, and the high thick right boring piston pin hole center line of a kind of yield rate and the correction positioner of outer face perpendicularity are provided.
The purpose of the utility model can reach through following technical proposals: the correction positioner of thick right boring piston pin hole center line and outer face perpendicularity comprises the seam seat; The correction detent mechanism that it is characterized in that thick right boring piston pin hole center line and outer face perpendicularity is installed on the seam seat; This mechanism has board-like lever and is fixed on the fulcrum shaft at middle part, and board-like lever upper end is installed two alternate each other and screw threads that pass through that be in same horizontal plane and is spun on bolt I and bolt II on the board-like lever; A hole is with at middle part, board-like lever lower end, inserts movable screw nail in the hole, and the screw bar overlaps a stage clip and is spun on the seam seat fixing; The fulcrum shaft two ends through axle sleeve respectively be fixed on the seam seat on support bar link to each other.
The utility model is compared prior art and is had following advantage:
1, bolt I on the board-like lever and bolt II are against on the workpiece outer face; The rotation and the translation of workpiece have been limited; Avoided workpiece pin-and-hole mouth circularity to lose circle effectively; And avoided the workpiece minor rotation that causes by lower platen fixation workpiece moment, eliminated workpiece outer face and the overproof phenomenon of bore hole center line perpendicularity.Accurately proofread and correct the perpendicularity of bore hole center line and outer face through two bolts, proofread and correct the location accurately.
2, improved the cylindricity of piston pin hole.In the workpiece process, bolt I and bolt II are pressed on the workpiece outer face all the time, prevent workpiece twisting, so just under the less situation of pressing plate thrust workpiece are fixed up.The normal pressure that workpiece receives reduces, and the deflection of bore hole just reduces, thereby has improved the cylindricity of institute's boring piston pin hole.
3, easy and simple to handle, efficient is high.

The specific embodiment
The correction positioner of thick right boring piston pin hole center line and outer face perpendicularity comprises seam seat (1); The seam seat is used to limit workpiece (blank before the finished product piston boring pin-and-hole) lower surface opening and moves, and the upper surface of workpiece then provides thrust to compress downwards by the pressing plate of device.Thick right boring piston pin hole center line (15) is installed on the seam seat (1) with the correction detent mechanism of outer face (17) perpendicularity; This mechanism have board-like lever (7) and be fixed on the middle part fulcrum shaft (8), fulcrum shaft (8) two ends through axle sleeve respectively be fixed on seam seat (1) on support bar (9) link to each other.Fulcrum shaft (8) can rotate in fixing axle sleeve, and board-like lever is that fulcrum rotates within the specific limits with the fulcrum shaft.Board-like lever (7) upper end is installed two alternate each other distances and the screw thread that passes through that be in same horizontal plane is spun on bolt I (5) and bolt II (16) on the board-like lever.The terminal head of two bolt screw rods is in order to reduce the contacted frictional force in same outer face (17), can wear into hemispherically, and two terminal lines of bolt screw rod have been confirmed residing orientation, the preceding outer face of workpiece bore.A hole is with at middle part, board-like lever lower end; Insert movable screw nail (11) in the hole; The screw bar overlaps a stage clip (14) and is spun on the seam seat (1) fixing; The effect of stage clip is that the lower end of board-like lever is lifted, board-like lever is rotated around fulcrum shaft (8) so that with board-like lever upper end to the outer face of workpiece near, be against the screw rod of bolt I (5) and bolt II (16) end hemispherical head on the outer face.Operation for ease, board-like lever can be with handle (13).During installing mechanism, make terminal line of two bolt screw rods and boring bar perpendicular.
When the utility model used, the right hand was pressed lower handle (13), outwards perk of the bolt I (5) of board-like lever (7) other end and bolt II (16).Left hand is placed on workpiece (3) on the seam seat (1), unclamps the right hand, and two bolt hemispherical head are pressed on the outer face (17), and turning of work piece lets the terminal hemispherical head of screw rod of two bolts all be against on the outer face slightly.Pressing the equipment clamping switch is pressed in workpiece surface with pressing plate and can begins to process the boring piston pin hole.Must debugging before the utility model uses.Judge that through measuring institute's boring pin-and-hole and outer face perpendicularity situation institute's boring pin-and-hole is unqualified.If deviation arranged, then one of in (16) two bolts of trimming bolt I (5) and bolt II in the screw-in amount of board-like lever (7), load new workpiece as stated above, the pin-and-hole of a workpiece is bored in boring again, measures again, debugs to accomplish till qualified again and debugs.Afterwards, can guarantee the thick right boring piston pin hole of high finished product rate.
