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
The present invention relates to the bush seat face of cylinder processing method in plunger displacement pump variable shell.
Background technology
The bush seat face of cylinder in existing CY14-1B series sloping tray axial plunger piston pump variable shell, in sleeping milling, with face and side cutter, process, as shown in Figure 1, face and side cutter 4 is contained on the main shaft 5 of horizontal milling machine 1, with clamping sleeve 3 and two end nuts 2, lock, the other end of main shaft 5 is supported on miller tailstock 6.Bush seat 7 is arranged in the fixture 9 on workbench, by workbench move left and right realize milling cutter 4 feedings, thereby process the bush seat face of cylinder.Main shaft 5 length that overhangs, because strength problem main shaft 5 diameters can not be too little, add the thickness of the clamping sleeve 3 of two ends compression face and side cutter 4, it is limited that cutter stretches into the degree of depth of bush seat, the center of circle on the plunger displacement pump variable shell top chock face of cylinder 8 from bush seat surface very close to, so face and side cutter 3 can not stretch into the interior processing of bush seat 7 completely, and must first on bush seat surface, process the small cylindrical surface 10 that a technique is used, allow the clamping sleeve 3 of face and side cutter not encounter bush seat 7 surfaces, just can make face and side cutter energy normal process.The blade of face and side cutter cannot be finely tuned, and when blade constantly weares and teares, the bush seat size processing also constantly diminishes, and when blade wears up to the size allowance below nominal size of bush seat permission, blade is just done for.
There is following problem in prior art: the not only time of waste processing small cylindrical surface, and technique is just in small cylindrical surface by the seal groove of variable body shell, just in time that seal groove and inner chamber milling is logical, not only affect the sealing of product, the serious product failure that even causes.The cost of charp tool is high, for solving the too fast problem of tool wear, bush seat face of cylinder size have to be amplified to 0.054mm, causes so again dimensional stability bad.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the bush seat face of cylinder processing method in a kind of plunger displacement pump variable shell, to reduce technological process, improve tool life, enhance productivity and the reliability of product.
Technical scheme of the present invention is achieved in that the bush seat face of cylinder processing method in plunger displacement pump variable shell, and angle head is contained on machine tool chief axis, and circular peripheral-mill is contained on the power transmission shaft of angle head, and bush seat is contained on fixture, and fixture is contained on level four axles.Angle head can stretch into the processing of bush seat inner chamber together with circular peripheral-mill, machine tool chief axis rotarily drives the power transmission shaft rotation of angle head, thereby drive circular peripheral-mill rotation, by workbench, move left and right to realize cutting feeding, thereby the face of cylinder of bush seat one side is processed.When four axles are together with after bush seat, fixture Rotate 180 °, just can process the face of cylinder of bush seat opposite side.
Good effect of the present invention is:
1, because the angle head that adopts transfer motion power transfer is directly processed the bush seat face of cylinder in vertical machining centre, angle head 12 can stretch into the processing of bush seat inner chamber together with circular peripheral-mill 13, be not subject to the restriction of 8 centers, the bearing block face of cylinder, cancelled the small cylindrical surface that in variable shell, processing technology is used.
2, reduced by one technological process, enhanced productivity more than 50%.
3, the blade of circular peripheral-mill can be finely tuned, and has avoided the change in size that causes because of cutter corner wear, can guarantee that bush seat dimensional tolerance is in 0.01mm.
4, the blade of cutter can process qualified products by continuous adjustment blade before limiting wear, improves tool life more than 2 times, if by 0.054 requirement of former dimensional tolerance, tool life improves manyly.
5, seal groove no longer communicates with inner chamber, has improved the sealing of product and the reliability of product.
Accompanying drawing explanation
Fig. 1 is existing horizontal milling machine top bearing shell seat face of cylinder machining sketch chart;
Fig. 2 is bush seat of the present invention face of cylinder machining sketch chart.
The specific embodiment
Below in conjunction with accompanying drawing 2 and embodiment, the present invention is elaborated.As shown in Figure 2, the bush seat face of cylinder processing method in plunger displacement pump variable shell is as follows:
One, cutter and bush seat are installed
Two, operation and principle
The inner chamber that angle head 12 heads stretch into bush seat 7 together with circular peripheral-mill 13 carries out slightly, half smart, smart machining.
Operation principle: when machine tool chief axis 11 rotates, drive its power transmission shaft rotation by the drive disk assembly in angle head 12, thereby drive circular peripheral-mill 13 to rotate; Machine tool chief axis 11 declines, and makes the head of angle head 12 stretch into the inner chamber of bush seat 7 together with circular peripheral-mill 13, according to bush seat 7 allowance number, to the face of cylinder of bush seat 7 one sides carry out slightly, half essence, fine finishining.Cutting feeding by workbench move left and right realize, so just realized the processing to the bush seat 7 one side faces of cylinder.When four axles 16 are together with after bush seat 7, fixture 15 Rotate 180s °, then repeat above-mentioned work step and just can realize the bush seat 7 opposite side faces of cylinder are processed.The running accuracy of four axles, by the accuracy guarantee of four axles itself, when precision has decline, also can compensate by program, guarantees the axiality of two cylindrical surface.
Circular peripheral-mill 13 of the present invention can be finely tuned, and when blade abrasion arrives lower size limit, can adjust size by adjusting micrometer adjusting screw, can guarantee the uniformity of bearing block face of cylinder size.
