Cross-shaped axle type automatic universal drilling device

Abstract

The invention discloses a cross-shaped axle type automatic universal drilling device. The cross-shaped axle type automatic universal drilling device comprises a processing tabletop, a four-jaw chuck which is detachably connected with the processing tabletop, a plurality main motors and a plurality of drill bits connected with the main motors. The cross axle type automatic universal drilling device is characterized in that a support is also arranged on the processing tabletop; a hydraulic cylinder is arranged at the central position of a support cross bar; the lower part of the hydraulic cylinder is connected to a pressure head; the four-jaw chuck is arranged under the pressure head; four jaws on the four-jaw chuck are separately connected with corresponding limiting blocks; straight teeth are arranged on the circumferential surface of the four-jaw chuck and are connected with a gear driving mechanism; a square hole is formed in the circumference of the four-jaw chuck; an auxiliary motor is connected onto the square hole; a through hole penetrates through a center position of the four-jaw chuck and a corresponding position of the processing tabletop; and a material receiving box is arranged under the through hole. According to the cross-shaped axle type automatic universal drilling device disclosed by the invention, two drill bits are arranged for simultaneously processing, so that the production efficiency is improved; and by adopting an improving structure, the device can automatically discharge after the processing is finished.

Description

【Technical field】 [0001] The invention relates to the technical field of cross-axis universal joint processing, in particular to the technical field of a cross-axis universal automatic drilling device. 【Background technique】 [0002] The traditional cross-axis universal joint is drilled with an ordinary drilling machine, which requires one hand to press the wrench, and the other hand to place and fix the workpiece, which is more dangerous. The iron filings produced by drilling are relatively long and are likely to cause injury to workers. Due to the manual drilling, a worker can only process one workpiece at a time, and the production efficiency is low. Each workpiece needs to drill 4 holes, and it is easy for workers to miss processing. Ordinary drilling machines use manual pressure wrenches, and the cutting speed needs to be controlled by manual power. If the speed is too fast, it will cause excessive heat generation, which will easily deform the workpiece and scrap it; ...

Problems solved by technology

However, this device is processed by a single drill bit, which is inefficient and needs to be taken out manually after processing. Due to the high temperature of the cross-axis universal joint that has just been processed, it is easy to cause injury to workers.
