Numerical control drilling machine locating press device for large excavator clamping plate machining

Abstract

The invention discloses a numerical control drilling machine positioning and pressing device for splint processing of a large excavator, which comprises a drilling machine platform, a support table, an X-direction positioning plate, a Y-direction clamping device, a slide rail, a sliding sleeve and a Z-down pressing device. The upper part of the drilling machine platform is provided with a support platform, and the upper left side of the support platform is fixedly connected with an X-direction positioning plate, and a Y-direction clamping device is installed on the support platform on the right side of the X-direction positioning plate. A fast limiting device is fixedly installed; the beneficial effect of the present invention is: the U-shaped bar rotates 90°, and the magnetic south pole and the magnetic north pole of the first magnet and the second magnet corresponding up and down are in the same direction, so that the U-shaped bar moves down and passes through The function of tightening the bolts further enhances the pressing force. During the processing, the generated iron filings are hung on the branch rods with serrated surfaces, so that the iron filings are cut off in time, and the rotating column rotates the iron filings. To the outside, the iron filings can be cleaned without stopping the machine.

Description

technical field [0001] The invention relates to the technical field of numerically controlled drilling machines, in particular to a positioning and pressing device for numerically controlled drilling machines for processing splints of large excavators. Background technique [0002] At present, large-scale excavator splints are drilled by manual drilling machines. This processing method requires marking the splints to locate the positions of the holes, and then fixing the splints on the machine tool through certain auxiliary methods to drill or sink holes. This operation The process is very cumbersome, making the processing efficiency of the splint very slow. Since the splints dug out usually have different sizes, when multiple holes need to be drilled or sunk multiple holes for splints of different sizes, it is not only necessary to frequently mark the positions of the multiple holes according to the required drawing size, but also to It is necessary to constantly re-select...

Problems solved by technology

[0004] But this positioning and pressing tool also has the following defects: one, the distance between the first Y-axis cushion block and the second Y-axis cushion block cannot be adjusted quickly and conveniently, so the splint cannot ensure the positioning effect in the Y direction well; two, the production The iron filings in the process rotate with the drill bit, which poses a safety hazard; 3. The chute and the slide rail cannot be fixed and positioned quickly, so the working efficiency is limited; 4. The installation of the working platform and the CNC drilling machine needs to be tightened one by one Bolts, also affect installation and removal efficiency
