Car part drilling device

Abstract

The invention belongs to the field of car part machining, and particularly discloses a car part drilling device. The car part drilling device comprises a rack, and the rack is rotationally connected with a first core shaft, a second core shaft and a third core shaft. The first core shaft is sleeved with a first driving gear, a coupling and a second driving gear, the coupling is in clamped connection with a shifting fork, and an air cylinder for driving the shifting fork is further arranged on the rack. A first fixed table is fixed to the first core shaft, and a plurality of drilling units arearranged on the first fixed table. A first driven gear, a second driven gear and a third driving gear are fixed to the second core shaft, and a second fixed table is fixed to the third core shaft. A clamp is arranged on the second fixed table, and a thread section is arranged on the third core shaft. The thread section is externally connected with a connecting sleeve, and a third driven gear engaged with the third driving gear is fixed outside the connecting sleeve. A piston barrel is arranged at the position, below the third core shaft, of the rack. By means of the scheme, the requirement ofmachining three holes of a rectangular structure in a car part at the same time is met.

Description

technical field [0001] The invention belongs to the field of auto parts processing and specifically discloses a drilling device for auto parts. Background technique [0002] Auto parts usually have many normal holes for the positioning of other parts. For positioning accuracy and reliable connection between parts, the relative position accuracy of these normal holes is very high. Due to the high stability of the triangle, three normal holes arranged in a triangle are generally processed on the auto parts, and the positions of these normal holes are required to be compact. [0003] The drilling device in the prior art includes a positioning seat, a fixture fixed on the positioning seat and a drill bit above the fixture. The fixture fixes the parts to be drilled on the positioning seat, and the relative movement of the drill bit and the positioning seat is used to realize drilling. hole. There are the following problems in this drilling device: 1, only one hole can be proces...

AI Technical Summary

Problems solved by technology

There are the following problems in this drilling device: 1, only one hole can be processed at a time, and the position of the other two holes can be positioned by using the processed hole, and the efficiency is very low; Errors in positioning are inevitable, and errors in each hole make it difficult to guarantee the positional accuracy of the final three holes; 3. The iron filings generated during the drilling process can only be collected manually after processing, which is time-consuming and laborious
