Abstract

The utility model discloses a device for cleaning the burr of a bore hole or an inner hole inside a circular pipe, aiming at providing a new cleaning way for cleaning the burr inside the inner hole. The device comprises an air pump, an pneumatic motor connected with the air pump by an aeration pipe, and a rotary knife holder connected with the driving end of the pneumatic motor; the circumference of the end surface of the rotary knife holder is distributed with knife holders with blades evenly; and the blades and the knife holders form a sliding pair by an embedded rail. The utility model has the advantages of completely cleaning the burr, the hard burr and other deposition inside the bore hole or at the inner side of the circular pipe; the utility model has good cleaning effect and high work efficiency and is capable of meeting the needs of mass production.

Description

A kind of device of removing hole bur in boring or the pipe

Technical field

The utility model relates to a kind of cleaning plant, and in particular, the utility model relates to a kind of device that is used to remove hole bur in boring or the pipe.

Background technology

In practical work and life, burr or deposit for boring or pipe inboard, basically all be that the jack rabbit that adopts external diameter to equal its internal diameter is cleared up,, have following shortcoming though this manner of cleaning up can reach the cleaning purpose to a certain extent:

(1) can not remove the boring or the hard burr of pipe inboard fully;

(2) cleaning efficiency is low, can't satisfy requirement of large-scale production.

The utility model content

Problem to be solved in the utility model overcomes the defective of above prior art exactly, provide a kind of based on vane pump or sliding-vane motor operation principle and the device of hole bur in the removing boring that designs or the pipe.

The technical solution of the utility model is: a kind of device of removing hole bur in boring or the pipe, comprise air pump, connect the air motor of described air pump and the rotary knife base that is connected with the drive end of described air motor by breather pipe, circumference uniform distribution is equipped with the knife rest of blade on the end face of described rotary knife base, and described blade and described knife rest constitute the slippage pair by inlaying track.

The beneficial effects of the utility model are:

(1) can clear up the boring or burr, hard burr and other deposit of pipe inboard fully;

(2) cleaning efficiency height can satisfy requirement of large-scale production.

Description of drawings

Fig. 1 is principle of compositionality figure of the present utility model;

Fig. 2 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with drawings and embodiments the utility model is described in detail.

By Fig. 1, Fig. 2 as seen, formation of the present utility model, the air motor and the rotary knife base that comprise air pump, be connected with described air pump by breather pipe; One end of described breather pipe 1 connects air motor 2, the drive end of described air motor 2 connects rotary knife base 7, circumference uniform distribution knife rest 3 on the end face of described rotary knife base 7, by set screw 5 and spacer 6 blade 4 is installed on the described knife rest 3, described blade 4 is by inlaying track and described knife rest 3 formation slippages pairs and can moving radially along the track on the described tool rest 3.

The quantity of described knife rest 3 can be provided with arbitrarily as required, is set to 3 in the present embodiment.

The utility model has adopted and a rotor has been installed in stator and the constituted mode of a plurality of retractable blades is installed on rotor based on the principle design of vane pump commonly used in the engineering machinery or sliding-vane motor.In specific design, described rotary knife base 7 is equivalent to rotor, and described blade 4 is equivalent to retractable blades, is cleared up object and is equivalent to stator.The rotary knife base 7 that is equivalent to rotor can rotate under the driving of described air motor 2, thereby drive knife rest 3 rotations of circumference uniform distribution on described rotary knife base 7 end faces, and make that to be embedded in the blade 4 that is equivalent to retractable blades on the described knife rest 3 overhanging with its rotation.

So the technique effect that is provided with is: when described rotary knife base 7 was in not rotation status, described blade 4 was hidden in inlaying in the track of described tool rest 3, and whole device external diameter is less, can enter boring or pipe endoporus; When described rotary knife base 7 is in the high speed rotation status, described blade 4 can be in the effect lower edge of rotary centrifugal force its inlay orbital drive to overhanging with described tool rest 3 agrees with mutually, thereby the external diameter of device is enlarged, and reach hole bur and sedimental purpose in removing boring or the pipe.

The utility model has the following advantages than prior art:

(1) has good removing effect, some deficiencies of the burr that has stayed when having solved with usual manner cleaning oil pipe or cased bore-bole;

(2) improve burr removing efficient, can save manpower and time in a large number, and easily reached high-quality production standard, can satisfy requirement of large-scale production;

(3) setting of high speed rotating blade not only can be removed general burr or deposit in the pipe fast, can also clear up the stimulate the menstrual flow hard burr of the bad cleaning of rule of original use.

Above with reference to accompanying drawing to the description of being illustrated property of the utility model, this description does not have restricted, shown in the drawings also is a kind of embodiment of the present utility model.Those skilled in the art should be understood that, can also carry out modification various forms or details to the technical solution of the utility model.Therefore, under the situation that does not depart from the utility model design aim, any modification that does not break away from the utility model design aim that anyone makes all should drop within the scope of the present utility model.

Claims

1. remove the device of hole bur in boring or the pipe for one kind, comprise air pump, it is characterized in that, it also comprises by breather pipe and connects the air motor of described air pump and the rotary knife base that is connected with the drive end of described air motor, circumference uniform distribution is equipped with the knife rest of blade on the end face of described rotary knife base, and described blade and described knife rest constitute the slippage pair by inlaying track.
