Description

Pipe end face cutter

Technical field

The utility model relates to a kind of pipe end face cutter.

Background technology

At present, the plane of small workpiece is polished or the plane of processing work all needs carry out on grinding machine, and traditional grinding machine body is big, can not move, consume electric power also, and the plane of some small workpiece polishes and often needs the scene to carry out, for example in the air-conditioning installation process, be placed on unnecessary tube connector outdoor usually, this tube connector opening part flare, carry four copper screw caps when dispatching from the factory, to make things convenient for the connection of indoor and outdoors air conditioner connecting pipe, install, but it is very difficult that existing machining tool is processed this horn mouth, usually earlier with file filing pipe section, with triangular scraper the burr in the pipe is scraped off again, then at bell mouth expanding, this traditional processing method not only wastes time and energy, and be difficult to reach quality standards, usually phenomenon that cause leaking gas happens occasionally because air conditioner connecting pipe connects bad, greatly reduces the quality and the efficient that install an air-conditioner.

On the other hand, must consider to be beneficial to the hand gripping and to the easy processing of workpiece to the craft of small workpiece processing, and traditional manual machining tool can not reach above-mentioned requirements.

Summary of the invention

The purpose of this utility model provides a kind of pipe end face cutter, is beneficial to that hand grips and to the easy processing of workpiece, have simple in structure, easy to use and good stable processing and result of use.For this reason, the utility model is mainly by body, big rap handle and clamp device are formed, body is curved, the main shaft middle part is positioned at the adjusting silk braid and joins with the inner jacket wall cunning of adjusting silk braid, the adjusting silk braid directly is arranged on the internal thread part of upper end body mesopore, the main shaft lower end Plane cutter upper center that is spirally connected, the main shaft upper end is positioned at outside the body mesopore upper surface and is provided with big strand handle, regulate silk braid lower surface and Plane cutter upper surface and be provided with compression spring, be provided with fixedly kerve in the body of Plane cutter lower end, fixedly be provided with the clamp device in the kerve, body one side spiral shell is provided with the standing screw of geometrical clamp pipe unit.The said structure design has reached the purpose of this utility model.

The utility model has the advantages that and be beneficial to that hand grips and the easy processing of workpiece, effect with portable processing object plane, can improve the quality pipe processing workpiece or that install an air-conditioner and efficient greatly, also has simple structure, of many uses, lower cost and good stable processing and result of use, and portable and operation, not consuming electric power.

Specific embodiments

To shown in Figure 2, a kind of pipe end face cutter mainly is made up of body 3, big rap handle and clamp device as Fig. 1.Body is curved, can make things convenient for hand to grip and to the easy processing of workpiece.Main shaft 2 middle parts be positioned at regulate silk braid 8 and with regulate the inner jacket wall cunning of silk braid and join, regulate on the internal thread part 10 that silk braid directly is arranged in upper end body mesopore 9, main shaft lower end Plane cutter 6 upper center that are spirally connected are installed and the replacing Plane cutter with convenient.The main shaft upper end is positioned at outside the body mesopore upper surface and is provided with big strand 1.Regulate silk braid lower surface and Plane cutter upper surface and be provided with compression spring 7.Be provided with fixedly kerve 5 in the body of Plane cutter lower end, fixedly be provided with the clamp device in the kerve.Body one side spiral shell is provided with the standing screw 4 of geometrical clamp pipe unit.The standing screw outer end is provided with rap 11.

Described clamp device by press from both sides 17 surely, live folder 14 and wing nut 15 form, be provided with the draw-in groove 13 of different-diameter between fixed folder and the folder alive, surely press from both sides front axle and establish tight bolt screw rod 16, tight bolt screw rod is fastened in the corresponding draw-in groove that presss from both sides front end of living and by the wing nut that is screwed onto on the tight bolt screw rod and adds the tightening folder and the folder top of living.The other end of living folder and deciding to press from both sides is provided with the biting hook 12 that mutual hook is connected.

During use, size dimension according to air conditioner connecting pipe, put it in the suitable draw-in groove of clamp device, both are bited into after one and tight bolt screw rod be fastened in the draw-in groove of the corresponding folder front end of living with biting hook, rotate wing nut, along tight bolt screw rod the fixed folder of living is tightened at wing nut, clamping work pieces, again the clamp device is inserted in fixedly in the kerve, rotate rap simultaneously and driving standing screw clamp device and body are fixed, process object surface and just in time be located at the Plane cutter lower end this moment.Clockwise, turning big strand rotates the drive main shaft, hold under the effect in adjusting silk braid external screw thread effect and compression spring, make main shaft drive the adjusting silk braid and move down along internal thread part, the Plane cutter that drives the main shaft lower end moves down, rotate big strand handle with hand, drive main shaft the Plane cutter of its lower end is rotated, cutter cutting processing object plane is when processing object plane reduces gradually, then to put end face to anchoring filament gradually close in the main shaft upper surface, reaches working depth.

When getting the processing object, the big strand handle of elder generation's reverse rotation, drive spindle axis counterclockwise rotation, hold under the effect in adjusting silk braid external screw thread effect and compression spring, make main shaft drive the adjusting silk braid and move up along internal thread part, the Plane cutter that drives the main shaft lower end moves up, when the convex edge of regulating the silk braid lower end holds in body mesopore lower surface, then main shaft can not be up, can only dally in regulating silk braid.The reverse rotation rap takes out object and gets final product opening set bolt and the fixed folder of living again.

In a word, the utility model is beneficial to that hand grips and to the easy processing of workpiece, has simple in structurely, and easy to use and good stable processing and result of use can be promoted the use of.
