After installation, the limiting end block 14 presses and limits the base part of the oil pump housing, as shown in the attached figure. Figure 1As shown, the clamping force point is at the edge of the hole in the base of the oil pump housing, which makes the force support more stable and avoids workpiece displacement and falling off due to cutting force. This is conducive to improving the stability of the oil pump housing clamping support and the machining accuracy. Then, the installed oil pump housing is machined by a cutting or drilling machine tool to complete the machining work.
[0024] Working principle or structural principle: Before operation, select the corresponding mounting positioning plate 9 and mounting positioning column 8 according to the model and specifications of the oil pump housing to be processed. First, install the mounting positioning column 8 on the upper part of the mounting slider 7 by screwing and tightening. Then, adjust the position of the four sets of mounting positioning columns 8 by sliding according to the hole distribution, so that the upper end of the mounting positioning column 8 is aligned and inserted into the through hole in the middle of the mounting positioning plate 9. After that, fit the mounting positioning plate 9 into the positioning groove on the upper part of the processing table 3 and complete the installation by fastening the plate body bolt column 11. Then lock and limit the mounting positioning plate 9, and complete the processing preparation work of the device. During processing, the lifting plate seat 5 is moved upward by the drive cylinder 4. Then, the oil pump housing seat is aligned and installed on the upper part of the processing table 3 using the mounting holes on the base of the oil pump housing seat. After installation, the upper end of the mounting positioning post 8 is aligned and inserted with the mounting holes on the base of the oil pump housing seat. Then, the four sets of limit end blocks 14 are tightened and installed on the upper end of the mounting positioning post 8 by screwing. After completion, the clamping button is pressed, and the lifting plate seat 5 is slowly moved downward by the drive cylinder 4, so that the lower part of the limit end block 14 is stably pressed against the base side of the oil pump housing seat, realizing the installation limit of the oil pump housing seat. The oil pump housing seat is positioned and installed by the mounting holes, which can ensure the installation and positioning accuracy of the workpiece. Moreover, the pressure point is on the edge of the hole in the base of the oil pump housing seat, and the force support is more stable, which can avoid the workpiece displacement and falling off due to cutting force. This is conducive to improving the stability of the oil pump housing seat clamping support and the processing accuracy. Then, the installed oil pump housing seat is processed by a cutting or drilling machine tool to complete the processing work.
[0025] In summary, this device adopts a hole-interlocking support type limiting installation structure based on the structural characteristics of the oil pump housing. Utilizing the mounting holes on the upper part of the oil pump housing as a positioning reference, the precise clamping and fixing of the oil pump housing can be achieved through the interlocking support of the mounting positioning pins 8 and the downward pressure support of the limiting end block 14. The oil pump housing is positioned and installed based on the mounting holes, ensuring the accuracy of workpiece installation and positioning. Furthermore, the pressure point is located at the edge of the holes in the base of the oil pump housing, resulting in more stable force support and preventing workpiece displacement or detachment due to cutting forces. This improves the stability of the oil pump housing clamping support and enhances machining accuracy. The mounting positioning pins 8 are supported and installed by the mounting slot 6 on the upper part of the lifting plate seat 5 and the mounting slider 7. The positions of the four sets of mounting positioning pins 8 can be flexibly adjusted through sliding adjustment. Combined with the interlocking positioning of the mounting positioning plate 9, which is detachably installed in the middle of the machining table seat 3, the positioning and installation requirements of oil pump housings of different specifications can be met, greatly improving the operational flexibility of the device.
