Multi-degree-of-freedom drilling machine

Abstract

The invention discloses a multi-degree-of-freedom drilling machine which comprises a bottom supporting seat, a truncated-cone-shaped mounting seat, a longitudinal retractable device, a sliding rail, aspindle box body, a motor, a drilling tool, a large cylinder, a small cylinder and balancing weights. A groove is machined in the large cylinder in the length direction of the large cylinder, and a rack is mounted in the groove. A supporting platform is mounted outside the large cylinder and comprises a sleeve, an n-shaped frame, a gear groove, a circular hole, a transverse retractable device, asupporting block, a cushion plate and a positioning plate. A stepped shaft is mounted in the circular hole of the n-shaped frame, and a gear is mounted on the stepped shaft and engaged with the rack for transmission. A positioner is mounted on the positioning plate, a water tank is mounted at the upper end of the bottom supporting seat, and an oblique lapping block is mounted on the inner wall ofthe water tank. A filtering net is placed on the oblique lapping block. A water pipe is mounted on one side of the water tank, and a filter and a vane pump are mounted on the water pipe. A flexible pipe is connected to a water outlet of the water pipe, and a spray head is mounted at one end of the flexible pipe.

Description

technical field [0001] The invention belongs to the technical field of drilling machines, in particular to a multi-degree-of-freedom drilling machine. Background technique [0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes in a workpiece. Usually the drill bit rotates as the main movement, and the axial movement of the drill bit is the feed movement. The drilling machine has a simple structure and relatively low machining accuracy. It can drill through holes and blind holes, replace special tools, expand, countersink, ream or tap. Wait for processing. During the machining process, the workpiece does not move, let the tool move, align the center of the tool with the center of the hole, and make the tool rotate (main movement). The characteristic of the drilling machine is that the workpiece is fixed and the tool rotates. [0003] The current drilling machine can adjust the vertical height and lateral position, and can realize r...

Problems solved by technology

[0003] The current drilling machine can adjust the vertical height and lateral position, and can realize rotation during use, but it is not convenient to clamp the workpiece during use, and at the same time, the position of the workpiece cannot be realized during the adjustment process. Adjustment, when the drilling machine is working, it is supplemented with coolant or water to cool down, but the coolant or water is not used twice, resulting in waste
