The functions to be realized by the locking block tooling pressure plate 13 and the lifting hole tooling pressure plate 18 are the same, the difference is that the heights of the locking block tooling cushion block 11 and the lifting hole tooling cushion block 16 are different, and the lifting hole tooling pressure plate 18 is different from the locking block tooling pressure plate 13 in that a transverse threaded hole is additionally arranged on the side surface of the lifting hole tooling pressure plate 18, because the lifting hole 200 on the side surface of the workpiece spindle sleeve 2 is circular, the tooling pressure plate 18 cannot stretch into the lifting hole tooling pressure plate to compress the workpiece spindle sleeve 2, a transverse half-round head tooling bolt 36 is inserted into the lifting hole 200 on the side surface of the workpiece spindle sleeve 2 to compress and fix the workpiece spindle sleeve 2.
The two round nuts 6, 10, 14, 19 are for more secure locking.
The waist-shaped hole on the locking block tooling pressing plate 13 and the waist-shaped hole on the lifting hole tooling pressing plate 18 are convenient for adjusting the positions.
The existing tool used in the process of finely boring a pin hole on a workpiece spindle sleeve 2 on a vertical machining center is used for supporting a cover plate mounting surface and a locking block end surface below the spindle sleeve by using equal-height blocks with three to four fixed heights. Due to casting and machining errors of parts, after one equal-height block contacts the end face, gaps may exist between the upper end faces of other equal-height blocks and the cover plate mounting surface below the spindle sleeve or the end face of the locking block, and the appropriate height is adjusted by heightening the heights of the equal-height blocks on the single side, so that the efficiency is low. The height of the bolt is controlled by moving the half-round head tool bolt on the tool upright post through the manual plate of the open spanner, so that the distance from the large end face of the main shaft sleeve to be processed to the end face of the main shaft of the machine tool can be adjusted, and the correction requirement before processing of a workpiece is met. Therefore, the efficiency of clamping and correcting the workpiece is effectively improved, and the cost of additionally manufacturing a tool due to the fact that the height of the equal-height block is not matched in the prior art is reduced. In addition, one side of the tooling pressure plate is in contact with the large end face of the main shaft sleeve, and the other side of the tooling pressure plate is in contact with the equal-height blocks with the height basically consistent with the height of the large end face of the main shaft sleeve, so that the height of a tooling cushion block is very high, the manufacturing cost of the tooling is high, the clamping is unstable, and potential safety hazards exist. This patent is through the up end of the locking block who compresses tightly work piece main shaft cover 2 and the lifting hole 200 of 2 sides of work piece main shaft cover, and the effectual height that compresses tightly that shortens to the cost of frock has been saved greatly, and the frock is more stable.
In the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
