Background
The existing tooling for processing cover plate parts is directly placed on a machine tool workbench, and contour dimensions of small cover plate parts are required to be manufactured in advance to form equal-height blocks and pressing plates. Because the outline dimensions of the small cover plate parts on the wind power gear box are very different, the same contour blocks and pressing plates cannot be used for clamping and fixing, and when the cover plate parts with the large outline differences are encountered, various different contour blocks and pressing plates are required to be manufactured, the clamping efficiency is low, and the cost of manufacturing a plurality of tools is additionally increased.
Moreover, according to the overall dimension of the cover plate type part on the wind power gear box provided by a designer, the lower plane for supporting the cover plate type part is manufactured in advance by the equal-height blocks, and as the interval between the T-shaped grooves on the machine tool workbench is far, the machine tool workbench meets small structural parts and can only be fixed by using a tool pressing plate with long length.
The disadvantages of the prior art are:
1. When the cover plate type parts with too large outline and dimension difference are met, various equal-height blocks with different heights and pressing plates with different lengths are required to be manufactured, and the tooling is high in cost.
2. The cover plate type part is pressed by the pressing plate, and the pressing force of the pressing plate is possibly inconsistent, so that the workpiece is easily stressed unevenly to deform, and the processing precision of the part cannot be effectively ensured for the cover plate with high processing requirement.
3. Cover plate type parts with different sizes are processed, equal-height blocks and pressing plates need to be switched back and forth, so that waiting time of a machine tool is long, and productivity of the machine tool cannot be fully utilized.
4. The upper part of the cover plate part is pressed and fixed through the pressing plate, if the pressing part is provided with a place needing to be processed, the pressing plate can interfere with a cutter of a machine tool, and therefore the machine tool cannot be processed.

The patent is a clamping frock of adjustable height that well box used when boring the pinhole above the big terminal surface in the vertical machining center.
As shown in fig. 1, 2 and 3:
the integral tooling platform 2 is placed on the machine tool workbench 1.
Through holes are formed in four angles in advance on the integral type tooling platform 2, T-shaped heads of T-shaped bolts 4 are installed in T-shaped grooves 1 'on the machine tool workbench 1, threaded portions of the T-shaped bolts 4 penetrate through the through holes 2' formed in advance on the integral type tooling platform 2, round nuts 3 are screwed on the T-shaped bolts 4, the round nuts 3 are tightly pressed on the integral type tooling platform 2 through tightening the round nuts 3, and the integral type tooling platform 2 is fixed on the machine tool workbench 1.
The cushion block 6 is directly placed on the integral tooling platform 2, plays a role in supporting the workpiece cover plate 5, and the workpiece cover plate 5 is placed on the cushion block 6, so that the workpiece cover plate 5 can be uniformly stressed according to the structure of the workpiece cover plate 5 in the use process.
The tooling pressing plate 7 is a rectangular steel plate with a certain thickness, and the side surface of the tooling pressing plate 7, which is in contact with the workpiece cover plate 5, is required to have good flatness, so that the tooling pressing plate 7 and the workpiece cover plate 5 can be fully contacted.
The lower part of the tooling pressing plate 7 is provided with a protruding structure 71 with a certain width, and the protruding structure 71 is embedded into a rectangular key slot 21 which is formed in advance on the integral tooling platform 2. The protruding structure 71 with a certain width is arranged below the tool pressing plate 7 to play a role of a key block, and the rectangular key groove 21 which is formed on the integral tool platform 2 in advance plays a role of guiding. The side of the tooling pressing plate 7 far away from the workpiece cover plate 5 is provided with a blind hole type threaded hole 70 in advance, the supporting block 10 is fixed on the integral tooling platform 2 in a welding mode, the tooling nut 9 is fixed on the supporting block 10 in a welding mode, the tooling bolt 8 is screwed in advance to be matched with and pass through the tooling nut 9, and the tooling bolt 8 is continuously screwed until the tooling bolt 8 can be screwed into the threaded hole 70 which is provided on the tooling pressing plate 7 in advance. Because the threaded holes 70 on the tool pressing plate 7 are blind holes, after the tool bolts 8 are screwed into a certain depth, the tool pressing plate 7 can be pushed to move in the rectangular key grooves 21 which are formed in advance on the integral tool platform 2 by continuously screwing the tool bolts 8, the movement of the tool pressing plate 7 is controlled until the side surfaces of the tool pressing plate 7 are in contact with the workpiece cover plate 5, and the tool pressing plate 7 presses the workpiece cover plate 5.
