Description
Technical field
The utility model is related to the clamp for machining with the tapered pole consent of axis formation angle in plunger pump cylinder body.
Background technology
Plunger pump has high pressure, huge discharge, can form a variety of variable modes, therefore occupies in Hydraulic Field critically important ground
Position.And cylinder body is one of vital part in plunger pump, it is related to the performance indications of whole product.Cylinder body tapered pole consent is
One of its important feature, need to ensure reference diameter, the diameter of plunger hole, roughness and form and position tolerance, the guarantor of multiple plunger holes
The accuracy of angle is demonstrate,proved, therefore finishing requirements are high, roughing requirement therewith also becomes very high, and especially tapered pole consent is pre-
Processing.Domestic plunger pump manufacturing enterprise all processes for the preprocessing of the tapered pole consent of cylinder body in Digit Control Machine Tool.Not only efficiency
It is low and greatly waste device resource, cause irrational expense.
Utility model content
The purpose of this utility model is to provide the low plunger pump cylinder body of a kind of angle accuracy, reliable in quality, cost
Cone-shaped plunger hole processing clamp.
The technical scheme that the utility model is taken to achieve the above object is：
A kind of cone-shaped plunger hole processing clamp of plunger pump cylinder body, including bottom plate, connect disk, column, three-jaw chuck, drill jig
Plate, Quick-change drill bush, cylinder body, mandrel, taper roll bearing, spring and steel ball, the mandrel are arranged on bottom plate, taper roller axle
Bearing sleeve is on mandrel, and three-jaw chuck connects disk by left and right two and is connected with taper roll bearing, and cylinder body is placed in three-jaw chuck
And clamped by three-jaw chuck, the lower end of column is arranged on bottom plate, and the upper end of column is connected with one end of bushing plate, drill jig
The other end of plate is connected with Quick-change drill bush, and Quick-change drill bush is matched with cylinder body and used, and the outside positioned at mandrel on bottom plate is uniform
Provided with multiple circular holes, one of those, which connects, is provided with spring eye between disk and bottom plate, spring and steel ball, and steel are provided with spring eye
Ball is located at the lower section of spring, and steel ball is matched with circular hole and used.
Further, bottom plate described in the utility model is incline structure, and its angle of inclination is 0-20 degree.
The utility model uses above-mentioned technical proposal, in plunger pump, and cylinder body has multiple plunger holes, and with axis in 5 ° of folders
Angle and it is uniformly distributed, process equipment is radial drilling machine, and the installation way of fixture is that chuck is clamped, positioning method is passes through drill jig
Positioning hole on plate carries out positioning drilling.The utility model clamp bottom board has an inclined-plane, by chuck fixation on this inclined-plane, just
It can guarantee that the Working position of tapered pole consent.Rotation is indexed using the spinfunction of circular cone ball bearing, cylinder is solved
Body tilts to put can produce very big radial load and axial force problem with own wt.The utility model is connecing disk and contacts baseplate
Plastic bruss is installed at face, prevents iron filings enter from causing to connect disk and rotate dumb.
