Double-guide rail radial drilling machine

Abstract

The invention discloses a double-guide rail rocker drilling machine, which comprises a base, wherein a mounting cavity is formed in the base, and a worm is rotatably connected in the mounting cavity;a first gear is fixedly sleeved on the worm, and a second gear is arranged in the mounting cavity; the second gear is rotatably connected with the inner wall of the mounting cavity through a rotatingrod, and one end, away from the second gear, of the rotating rod runs through the inner wall of the mounting cavity and is fixedly connected with a rotary knob; two screw rods are rotatably connectedin the mounting cavity, and a third gear is fixedly sleeved on the screw rod; one end of the screw rod runs through the inner top of the mounting cavity and extends outwards, and one end of the screwrod runs through the inner top of the mounting cavity and extends outwards; the extending end of the screw rod is sleeved with a gear rack through threads, and the outer wall of the gear rack are fixedly connected with two guide rails; a guide groove is formed in the inner wall of a bearing block. The two guide rails are arranged on the outer wall of the gear rack, thereby improving the stabilityof the bearing block when sliding on the gear rack, and effectively improving the precision control of the sliding distance of the bearing block on the gear rack.

Description

technical field [0001] The invention relates to the technical field of radial drilling machines, in particular to a double guide rail radial drilling machine. Background technique [0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes in a workpiece. Generally, the rotation of the drill bit is 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. 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 rotate the tool. The characteristic of the drilling machine is that the workpiece is fixed, the tool rotates and feeds along the direction of the spindle, and the operation can be manual or motorized. In order to process oblique holes, vertical...
