1. in the batch processing process, the hole can be rotated for a plurality of times after the working platform of the processing center is accurately positioned for one time conveniently, the clamping bottom plate can be arranged at the designated position of the working platform at the moment, when the plate is processed, only the processed part needs to be clamped on the clamping bottom plate, the processed part only needs to be replaced on the clamping bottom plate after the processing is finished, the frequent positioning is not needed, and the processing precision is effectively improved.
2. When drilling the machined part, a plurality of processing plates can be stacked on the medium density board in sequence, and all the processing plates can be rotated by utilizing the locking parts, so that the processing plates can be rotated in batches
3. The middle-density board can effectively isolate the clamping bottom plate and the machined part, and effectively protects the clamping bottom plate and the drill bit.
Compared with the prior art, the utility model can effectively reduce invalid working hours brought by clamping and aligning when in use, also improves the positioning precision of the plate, has simple operation and high feasibility and is convenient for popularization and use.
Furthermore, a plurality of U-shaped grooves for positioning are symmetrically arranged on two sides of the clamping bottom plate. The installation of the clamping bottom plate is convenient.
Further, the locking piece is a hexagon bolt or an inner hexagon bolt. Hexagonal bolts can be used at positions far away from holes to be processed, and inner hexagonal bolts are used at positions close to the holes to be processed.
Furthermore, one side of the clamping bottom plate, which is far away from the middle density plate, is provided with a plurality of anti-skid protrusions. The antiskid efficiency is improved.
Furthermore, one side of the clamping bottom plate facing the middle density plate is provided with a mounting groove for mounting the middle density plate. The installation of the medium density fiberboard is convenient.
