Description
Technical field
The present invention relates to the clamp for machining of the tapered pole consent of angle is formed in plunger pump cylinder body with axis.
Background technology
Plunger displacement pump has high pressure, huge discharge, can form various variable modes, therefore occupies critically important ground in Hydraulic Field
Position.And cylinder body is one of vital part in plunger displacement 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 card angle, therefore finishing requirements are high, roughing therewith requires also to become very high, and especially tapered pole consent is pre-
Processing.Domestic plunger displacement 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.
The content of the invention
It is an object of the invention to provide a kind of angle accuracy, reliable in quality, the taper of the plunger pump cylinder body of low cost
Plunger hole processing clamp.
The present invention for achieving the above object and the technical scheme taken is：
A kind of cone-shaped plunger hole processing clamp of plunger pump cylinder body, including base 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 is arranged on base plate, taper roller axle
On mandrel, three-jaw chuck is connect disk and is connected with taper roll bearing for two bearing sleeve by left and right, and cylinder body is placed in three-jaw chuck
And clamped by three-jaw chuck, the lower end of column is arranged on base 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 base plate is uniform
Multiple circular holes are provided with, one of those connects and be provided between disk and base plate spring eye, 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, base plate of the present invention is incline structure, and its angle of inclination is 0-20 degree.
The present invention adopts above-mentioned technical proposal, and in plunger displacement pump, cylinder body has multiple plunger holes, and with axis in 5 ° of angles
And be uniformly distributed, process equipment is radial drilling machine, and the installation way of fixture is chuck clamping, and positioning mode is by bushing plate
Location hole carry out positioning drilling.Present clip base plate has an inclined-plane, by chuck fixation on this inclined-plane, it is ensured that cone
The Working position of shape plunger hole.Using the spinfunction of circular cone ball bearing indexed rotation, solve cylinder body and incline pendulum
Putting can produce very big radial load and axial force problem with own wt.The present invention is connecing installation plastics at disk and base plate contact surface
Brush, preventing iron filings from entering causes to connect disk and rotates dumb.
