The upper end of the main shaft is provided with a big twist handle, and the lower head face of the regulating screw sleeve and the upper head face of the plane cutting knife are provided with pressure springs. A fixed bottom cut is arranged in the body of the lower end of the plane cutting knife, and a clamp device is arranged in the fixed bottom cut. One side of the body is provided with a fixed screw rod in a screwing way for fixing the clamp device, and one end of the fixed screw rod is provided with a small twist handle. The tube head face cutting knife has the advantages of simple structure, convenient use, wide use, lower cost and good and good and stable processing and use effects, the quality and efficiency of processing tube workpieces can be greatly improved, and the tube head face cutting knife can be popularized and used.

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.

Summary of the invention

The purpose of this utility model provides a kind of pipe end face cutter, has simple in structurely, easy to use, can improve the quality and the efficient of pipe processing workpiece greatly, and also has lower cost and good stable processing and result of use.The utility model adopts main shaft to be positioned at the adjusting silk braid and joins with the inner jacket wall cunning of adjusting silk braid for achieving the above object, the internal thread part of regulating silk braid and upper end body mesopore is spirally connected, the main shaft lower end connects the Plane cutter upper end, the main shaft upper end 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, and standing screw one end is provided with the rap handle.The said structure design has reached the purpose of this utility model.

The utility model has the advantages that 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

Extremely shown in Figure 2 as Fig. 1, a kind of pipe end face cutter, mainly by body 3, big rap handle and clamp device are formed, main shaft 2 is positioned at adjusting silk braid 8 and joins with the inner jacket wall cunning of adjusting silk braid, the internal thread part 12 of regulating silk braid and upper end body mesopore 9 is spirally connected, the main shaft lower end connects Plane cutter 6 upper ends, the main shaft upper end 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 4 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 11 of geometrical clamp pipe unit, and standing screw one end is provided with rap 10.

Described clamp device by press from both sides 18 surely, live folder 14 and wing nut 16 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 15, 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 17 that mutual hook is connected.Plane cutter and fixedly be provided with workpiece fixing hole 5 in the body between the kerve.

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, regulating under the effect of silk braid external screw thread, main shaft is being driven 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, regulating under the effect of silk braid external screw thread, 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 simple in structure, and is easy to use, of many uses, can improve the quality and the efficient that install an air-conditioner greatly, and also has lower cost and good stable processing and result of use, can promote the use of.
