Drilling tool for gear shafting rocker arm

Abstract

The invention belongs to the field of automobile part machining, and particularly discloses a drilling tool for a gear shifting rocker arm. A machine frame is fixedly connected with a workbench, a first bevel gear, a second bevel gear and a third bevel gear are rotationally connected to the machine frame and above the workbench, the first bevel gear and the third bevel gear each is in threaded connection with a first screw rod, a connecting rod is hinged to the machine frame, the upper end of the connecting rod is hinged to the first screw rod, and a clamping plate is hinged to the lower end of the connecting rod; the second bevel gear is in threaded connection with a second screw rod, a piston barrel is fixedly connected to the machine frame, a piston is slidably connected in the piston barrel, the lower end of the second screw rod is fixedly connected with the piston, and the lower side of the piston is fixedly connected with a hollow mandrel; and the mandrel comprises an air inlet section, a throat portion and an air outlet section which are arranged from top to bottom, the inner diameter of the air outlet section is larger than the inner diameter of the throat portion, and thelower end of the air outlet section is fixedly connected with a drill bit. By the adoption of the scheme, the problems that scrap iron generated during drilling is required to be cleaned manually, andtime and labor are wasted are solved.

Description

technical field [0001] The invention belongs to the field of automobile parts processing, and in particular relates to a drilling tool for a gear shift rocker arm. Background technique [0002] In a manual transmission, it is generally necessary to set up a shift handball, a shift rocker device, a shift fork shaft structure, etc. to realize manual shifting of gears. To realize gear selection and gear shifting, the driver controls the action of the gear shift rocker arm device by operating the gear shift handball, and the action of the gear shift rocker arm device can drive the shift fork shaft to move, thereby completing gear shifting. Therefore, the gear shift rocker device is an important part connecting the gear shift handball and the shift fork shaft structure. [0003] The gear shift rocker arm needs to be machined with mounting holes during the machining process. The usual processing method is: fix the gear shift rocker arm, and use the relative movement of the drill ...
