Abstract
The invention provides a pen type pneumatic drill, and relates to a hand-hold type drilling machine driven by high-pressure gas, particularly to a tool for drawing, drilling and mounting screws in mechanical processing. In the existing mechanical manufacturing and drawing manner, a sunk trace left by knocking a sharp cylinder by a heavy object is used as a mark; the manner has the following defects of no safety, low efficiency, unclear marks, easiness in losing of the marks, and inconvenience in drilling small holes, and the pen type pneumatic drill mainly aims at solving the problem of the manner. Inner cylinders of the pneumatic drill of the pen type pneumatic drill provided by the invention are connected with an outer cylinder by clamping of a bayonet, each inner cylinder consists of at least three sections, the two inner cylinders are connected through a pneumatic turbine body, a gas inlet is formed in one end of the outer cylinder, a button switch for controlling the gas inlet is arranged at one end of the outer cylinder, and a bit is arranged at the other end of the outer cylinder. The pen type pneumatic drill provided by the invention has the advantages of low cost, simplicity in operation, low failure rate and safety in usage.
Description
Technical field
The present invention relates to a kind of hand-held pneumatic drilling machine, a kind of by drive of high-pressure gas hand drill specifically, be mainly used in machining drawing, punching and the pneumatic brill of screw is installed.
Background technology
The at present machine-building instrument used of drawing is, adopting weight to knock the left dent mark of coming of sharp-pointed cylinder is mark.This mode has following several shortcoming: 1. dangerous; 2. efficiency is low; 3. mark is unintelligible, easily loses.At machine, add in process and need to beat the not high aperture of ask for something, can adopt drilling machine processing, but the method too bothers.
Summary of the invention
The object of the invention is in order to overcome above-mentioned deficiency, and provide a kind of easy to operate, applied widely, and the pneumatic brill of low-cost pen type.
Technical solution of the present invention is: the inner core of the pneumatic brill of pen type is connected in urceolus by seam screens, inner core is comprised of at least three joints, between two inner cores, by air impeller body, connect, the press button that is provided with air inlet and control air inlet on one end of urceolus, the other end of urceolus is provided with drill bit.
The cavity of giving vent to anger that has non-centripetal angle equipotential on the nose circle face of the inner core described in technical solution of the present invention, connects the cavity on two inner cores by air impeller body.
Drill bit described in technical solution of the present invention is connected on inner core by square bayonet socket.
The present invention is simple in structure, and cost is low, uses safety, efficiency high.And failure rate is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, in the urceolus 1 of pneumatic brill, be provided with inner core 2, inner core 2 is rotating main bodies of the present invention, and the mode by seam screens is fixed in urceolus 1; Inner core 2 is comprised of at least three joint inner cores 2, between two inner cores 2, by air impeller body 3,8, connect, concrete connected mode is, on the nose circle face of inner core 2, have the cavity of giving vent to anger of several non-centripetal angle bisectings position, the cavity of giving vent to anger on inner core 2 is located at a side of its semicircle, between two adjacent inner cores 2, the cavity of giving vent to anger on inner core 2 is with upper-lower position setting, by air impeller body 3,8, the cavity on two inner cores 2 is connected, using gases at high pressure as the rolling bearing of inner core 2, and duplex bearing one on the other; One end at urceolus 1 is radially provided with high pressure gas air inlet 4, and this end of urceolus 1 is connected with the press button 5 of a control air inlet 4, and press button 5 is comprised of button and spring 6, and press button 5 resets by spring 6, and locates by the seam on urceolus 1; On the other end of urceolus 1, be provided with drill bit 7, the logical square bayonet socket of drill bit 7 is connected on inner core 2; Operation principle: gases at high pressure are connected on the air inlet 4 on urceolus 1, during button on pressing the button switch 5, the hole on press button 5 overlaps with the air inlet pore 4 on urceolus 1, and gases at high pressure are pressed into inner core 2, gases at high pressure spray from air impeller body 3,8, drive inner core 2 to rotate.The area that pore on urceolus 1 overlaps with hole on press button 5 is directly controlled throughput, thereby controls the speed of drill bit 7.And the air cushion bearing that the gas of ejection can rotate as inner core 2 from air impeller body 3,8.Thereby make it normal rotation.
