Example Embodiment

[0014] Attached below figure 2 The present invention is described in detail with embodiment. like figure 2 As shown, the machining method of the cylindrical surface of the bearing seat on the variable housing of the plunger pump is as follows:

[0015] 1. Tool and bearing seat installation

[0016] Install the angle head 12 on the machine tool spindle 11; the disc milling cutter 13 is installed on the transmission shaft of the angle head 12, and the transmission shaft of the angle head 12 forms an angle of 90° with the machine tool spindle 11, so the blade of the disc milling cutter 13 and the bearing bush The seat 7 (or worktable) is parallel; the bearing seat 7 is installed on the fixture 15, positioned by the mandrel on the fixture 15, and oriented by the process screw hole, the large plane of the bearing seat 7 is parallel to the machine table; the fixture 15 is installed on the horizontal On the four-axis 16, the horizontal four-axis can rotate within a horizontal ra...

Abstract

The invention provides a method for processing a bearing seat cylinder surface on a variable housing of a plunger pump. The method is characterized in that an angle head is mounted on a main shaft of a machine tool; a circular cutter is mounted on a transmission shaft of the angle head; a bearing seat is mounted on a clamp which is mounted on four horizontal axles; the angle head and the circular cutter can extend into an inner chamber of the bearing seat to process together; the main shaft of the machine tool rotates to drive the transmission shaft of the angle head to rotate so as to drive the circular cutter to rotate, and a workbench moves left and right to realize cutting and feeding, thus the cylinder surface on one side of the bearing seat can be processed; and when the four axles rotate at 180 degrees together with the bearing seat and the clamp, the cylinder surface on the other side of the bearing seat can be processed. According to the method, the angle head and the circular cutter extend into the inner chamber of the bearing seat to process; a small cylinder surface for process of the variable housing is removed; and the process is reduced, so that the production efficiency and product reliability can be improved.

Description

technical field [0001] The invention relates to a method for processing a cylindrical surface of a bearing bush seat on a variable displacement housing of a plunger pump. Background technique [0002] The cylindrical surface of the bearing pad seat on the variable housing of the existing CY14-1B series swash plate axial piston pump is processed by a three-sided milling cutter on a horizontal milling machine, such as figure 1 As shown, the three-sided edge milling cutter 4 is installed on the main shaft 5 of the horizontal milling machine 1, and is locked with the compression sleeve 3 and the nuts 2 at both ends, and the other end of the main shaft 5 is supported on the tailstock 6 of the milling machine. The bearing pad seat 7 is installed in the fixture 9 on the workbench, and the milling cutter 4 is fed by the left and right movement of the workbench, thereby processing the cylindrical surface of the bearing pad seat. The main shaft 5 is overhanging and elongated. Due to ...
