Problems solved by technology

[0002] In many bases or connectors, in order to achieve special connections, it is necessary to drill some inclined and flat holes, but because the drill bits of the current drilling rig are all vertical or horizontal, and the drill bits are fixed; so in order to drill out For the inclined and flat holes on the workpiece, it is necessary to make the workpiece inclined to the drill when clamping the workpiece; therefore, for holes with different inclination angles on the workpiece, it is necessary to design different tooling, which makes the cost higher and replaces it with different tools. For holes with inclined angles, it is necessary to reinstall tooling and positioning fixtures, so the processing efficiency is also low

Abstract

The invention discloses a drilling machine with a variable-angle drill bit and relates to a drilling device. The drilling machine with the variable-angle drill bit comprises a rack, a rotary seat, a drive portion and a drilling portion. The rotary seat is rotationally connected to the rack. The drilling portion comprises a transmission shaft, a sleeve, a feeding block and the drill bit. The sleeve is rotationally connected to the rack. An internal thread is arranged in the sleeve. An external thread is arranged on the feeding block. The feeding block is arranged in the sleeve and matched with the sleeve in a threaded manner. One end of the feeding block is provided with an internal spline. The drill bit is fixedly connected to the other end of the feeding block. The angle of the drill bit can be changed by rotating the sleeve. One end of the transmission shaft is connected with the spline in sliding fit with the feeding block. The transmission shaft is connected with the rotary seat through a universal joint so that variable-angle power transmission can be achieved. A fastening screw is arranged between the sleeve and the rack so that the sleeve can be fastened to the rack.

Description

technical field [0001] The invention relates to a drilling device, in particular to a drill bit variable angle drilling machine. Background technique [0002] In many bases or connectors, in order to achieve special connections, it is necessary to drill some inclined and flat holes, but because the drill bits of the current drilling rig are all vertical or horizontal, and the drill bits are fixed; so in order to drill out For the inclined and flat holes on the workpiece, it is necessary to make the workpiece inclined to the drill when clamping the workpiece; therefore, for holes with different inclination angles on the workpiece, it is necessary to design different tooling, which makes the cost higher and replaces it with different tools. For holes with inclined angles, it is necessary to reinstall the tooling and position the fixture, so the processing efficiency is also low. Contents of the invention [0003] The present invention intends to provide a drill bit variable...
