Abstract

A cavity workpiece inner wall drilling device, which is composed of a frame, a unit head, a unit head elevation and subsidencei device, an aiguille driven by the unit head, a worktable with a clamp and also has an aiguille strut. One end of the aiguille is connected fixedly with the unit head by a union body, the unit head drives the aiguille by a belt pulley transmission structure, the active belt pulley transmission wheel of is arranged on the main shaft of the unit head and the passive pulley transmission wheel is arranged on the other end of the aiguille strut far from the unit head, and connected with the aiguille. The aiguille arranged on the end of the aiguille strut far from the unit head can extends inside the cavity workpiece, the unit head drives the aiguille to rotate by the belt pulley transmission structure and processes drilling to the inner wall of the workpiece, the process procedure is simple, the drilling and then sealing and blocking to the outer wall of the workpiece and the polishing process to the surface both can be omitted. Therefore, the work efficiency is improved greatly, which also can save the work time, material and aiguille, the aiguille can't swing with high process accuracy and yield.

Description

Cavity Workpiece Wall Drilling Device

Technical field

The utility model relates to a kind of processing work drilling equipment, particularly a kind of Cavity Workpiece Wall Drilling Device.

Background technology

Often need hole at the inwall of cavate workpiece in field of machining, process with ordinary machine tool at present, its composition comprises: frame, unit head, the drill bit, the unit head lowering or hoisting gear that are driven by unit head and the workbench that has anchor clamps.For wave filter housing with a plurality of rectangular cavity, if wall boring within it, utilize existing process equipment, its procedure of processing is as follows: workpiece is located by anchor clamps on workbench, holes on the workpiece outer wall with drill bit earlier, drill bit stretches into from outer cinclides then, to inwall boring, after the inwall hole drill is good, withdraw from drill bit, fill up cinclides outside this with slightly larger in diameter in the aluminium bar in outer wall aperture, and polish the outer wall surfaces externally and internally.This manufacturing procedure is comparatively complicated, wastes time and energy, and efficient low and the waste material and the energy when inwall and outer wall distance are big, can cause the swing of drill bit, and the reduction machining accuracy causes the percent defective height.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and the Cavity Workpiece Wall Drilling Device that a kind of manufacturing procedure is simple, working (machining) efficiency is high is provided.

The technical scheme that its technical problem that solves the utility model adopts is as follows: a kind of Cavity Workpiece Wall Drilling Device, form the drill bit comprise frame, unit head, unit head lowering or hoisting gear, to drive by unit head, the workbench that has anchor clamps, it is characterized in that: have drill bit pole, the one end is fixedlyed connected with unit head by connector, unit head drives drill bit by pulley transmission mechanism, its drive pulley is contained on the dynamic head main spindle, its driven pulley is contained in the other end of drill bit pole away from unit head, and the driven pulley axle is connected with drill bit.

The beneficial effects of the utility model are as follows: be contained in drill bit pole and can stretch into cavate workpiece inside away from the drill bit of the first end of power, unit head drives drill bit by pulley transmission mechanism and rotates, directly the workpiece inwall is holed, manufacturing procedure is simple, has saved to the workpiece outer wall hole the earlier polishing on shutoff again and surface and has handled, and production efficiency improves greatly, save man-hour, material and the energy, drill bit can not swung, machining accuracy height, yield rate height.

Description of drawings

Fig. 1 is the utility model Cavity Workpiece Wall Drilling Device structural representation.

Fig. 2 be among Fig. 1 drill bit pole away from end power first end structure cross-sectional schematic.

Label among Fig. 1, Fig. 2: the rectangular cavity in 1-unit head, 2-connector, the 21-connector, 3-main shaft, 4-drill bit, 41-bit sub, 5-workbench, 51-anchor clamps, 6-drill bit pole, 7-workpiece, 8-driven pulley, 81-driven pulley axle, the bit sub insertion groove of 82-driven pulley axle, 9-drive pulley, 10-belt, 11-bearing, 12-bearing, 13-internal axle sleeve, 14-internal axle sleeve, 15-gap slot, 16-screw.

The specific embodiment

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.But the utility model is not limited to given embodiment.

As Fig. 1, shown in Figure 2, originally be to use novel Cavity Workpiece Wall Drilling Device, form and comprise frame (traditional frame, do not draw among the figure), unit head 1, unit head lowering or hoisting gear (traditional lowering or hoisting gear, do not draw among the figure), drill bit 4 by unit head 1 drive, the workbench 5 that has anchor clamps 51, this device also has a drill bit pole 6, the one end is fixedlyed connected with unit head 1 by connector 2, unit head 1 drives drill bit 4 by pulley transmission mechanism, its drive pulley 9 is contained on the dynamic head main spindle 3, its driven pulley 8 is contained in the other end of drill bit pole 6 away from unit head 1, and driven pulley axle 81 is connected with drill bit 4.
