Abstract
The invention discloses a camshaft side hole machining clamp, wherein a positioning plate which forms an oblique angle alpha with the bottom plane of a base is arranged above the base, the middle part of the positioning plate is provided with a positioning hole vertical to the positioning plate and a positioning pin below the positioning hole, and a movable pressing plate and a pressing screw are arranged on one side of the positioning plate. The further improvement is that the movable pressure plate is a hook-shaped sliding pressure plate sleeved on the positioning plate, and the positioning plate is provided with a drill bushing positioned above the positioning hole. The invention is used for processing the side hole on the camshaft of the gasoline engine, has convenient assembly and disassembly and small positioning error, can improve the processing efficiency and the processing precision, and is suitable for batch production.
Description
Technical field
The present invention relates to a kind of boring clamp for machining, particularly camshaft flank hole processing clamp.
Background technology
Camshaft is a strength member of general gasoline engines, and camshaft side face and camshaft axis have a tilt angle alpha, and with the gear face of camshaft one end the centre-to-centre spacing requirement is arranged, and it is bigger to add the man-hour difficulty, must accurately locate and reliably compress.At present the mode of locating and clamping with camshaft small end cylindrical and removable pin is adopted in the processing of camshaft side face usually, because there is mismachining tolerance in the small end cylindrical, and removable pin has certain fit tolerance, both produce a very large impact the lateral aperture machining accuracy in the accumulation meeting, and above installation way efficient is also lower, is not suitable for producing in batches.
Summary of the invention
The object of the present invention is to provide and a kind ofly can improve machining accuracy and working (machining) efficiency, be fit to the clamp for machining of the camshaft side face produced in enormous quantities.
Technical scheme of the present invention is: this clamp structure feature is the location-plate that is provided with above base with base baseplane bevel α, there is the alignment pin perpendicular to the locating hole of location-plate and locating hole below the location-plate middle part, and location-plate one side is provided with movable pressing plate and housing screw.
Further scheme is: described movable pressing plate is the hook-type sliding clamp that is enclosed within on the location-plate; Described location-plate is provided with the drill bushing that is positioned at the locating hole top, and the bullport perpendicular to the base baseplane is arranged on the drill bushing.
In the above scheme, the oblique angle α of location-plate and base baseplane is camshaft side face that Element Design requires and the inclined angle alpha between the camshaft axis, during use, the small end of camshaft is passed the locating hole of location-plate, gear medial surface and locating hole end face are adjacent to, and making the alignment pin on the location-plate insert the gear pin-and-hole, mobile again hook-type sliding clamp holds out against the gear shaft end surface with housing screw, thereby realizes the accurate location of workpiece and reliably compress.Subsequently anchor clamps are placed on the platen together with workpiece, but just process side face.This cramp assembling and disassembling is convenient, utilizes gear side and alignment pin location, and error is little, can improve working (machining) efficiency and machining accuracy, is fit to produce in batches.In addition, on location-plate, be provided with drill bushing, then further improve boring effect and machining accuracy.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Referring to accompanying drawing, the plane becomes the inclination angle of 90 °-α on the base 1 with the baseplane, wherein α is the lateral aperture on the camshaft 8 and the angle of camshaft axis, the location-plate 2 that is fixed on plane on the base is perpendicular to last plane, with base baseplane bevel α, there is the alignment pin 3 perpendicular to the locating hole of location-plate and locating hole below the location-plate middle part, locating hole end face and base baseplane bevel α, hook-type sliding clamp 5 is enclosed within on the location-plate, can move up and down, pressing plate is provided with housing screw 4, and location-plate is provided with the drill bushing 6 that is positioned at the locating hole top, and the bullport 7 perpendicular to the base baseplane is arranged on the drill bushing.
Claims (3)
1, a kind of camshaft flank hole processing clamp, it is characterized in that above base, being provided with location-plate with base baseplane bevel α, there is the alignment pin perpendicular to the locating hole of location-plate and locating hole below the location-plate middle part, and location-plate one side is provided with movable pressing plate and housing screw.
