Technical field
The present invention relates to a kind of grinding tool, particularly about a kind of milling tools of self-adapting tube otch.
Background technology
Present most of plant equipment for industries such as machine-building, communications and transportation, the form that pipe-line system is carried with pneumatic, hydraulic pressure or fluid plays an important role at aspects such as the execution of equipment, control, brakings, its reliability requirement height of pipe-line system is used extremely general.Tubing processing is the requisite process procedure of manufacturing, and the inside and outside incision in tubing cutting back can produce a large amount of burrs, before welding or using, must polish to it.At present, lack the specific purpose tool be applied to this occasion, adopt scraper and emery wheel to carry out the manual grinding of inside and outside otch respectively more, in this case, 1, grinding efficiency is low, big to caliber, weight is big, the pipe of inconvenient clamping is difficult to polishing; 2, polishing is of poor quality, influences the quality of follow-up processing (as welding); 3, the residual burr of inwall can influence the cleannes of working media; 4, poor stability brings inconvenience to production.
Summary of the invention
At the problems referred to above, the objective of the invention is to propose a kind of different tube diameters and wall thickness of being applicable to, the finishing tool for self-adapting tube kerf that can carry out inside and outside otch polishing simultaneously.
For achieving the above object, the present invention takes following technical scheme: a kind of finishing tool for self-adapting tube kerf, it comprises that one connects the plinth of power, described plinth top offers the annular groove that a circle leaves boss, described plinth top connection one has the protection sleeve of base, described base is provided with a through hole that is communicated with described groove, be symmetrically arranged with two limited blocks on the described base, offer vertical strip through hole on the correspondence position of described two limited blocks and described sleeve respectively, pass two pairs of described strip through holes and connect an A shape internal mold by two bolts that have wing nut, the inclined upper surface of described A shape internal mold is provided with the polishing emery stick, and the lower end is connected with boss in the described annular groove by the through hole that a spring passes on the described base; Be decussation with described A shape internal mold and be provided with the V-arrangement external mold of being made up of two-half die, described V-arrangement external mold is fixed on the described base, and the inclined upper surface of described V-arrangement external mold is provided with the polishing emery stick.
The interior die holder that described A shape internal mold lower end fixedly connected is supported, described interior die holder lower end is connected with described spring.
The two-half die of described V-arrangement external mold is fixed on the described base by an outer mould base respectively.
Described base is connected with described sleeve split.
Wing nut on the described bolt is arranged on the outside of described sleeve.
The present invention is owing to take above technical scheme, and it has the following advantages: 1, the present invention is provided with two A shape internal mold and V-arrangement external molds that are the cruciform shape layout, makes the pipe fitting inside and outside wall polish simultaneously, the efficient height.2, the present invention is provided with axial limiting mechanism on A shape internal mold, but makes the self adaptation adjustment in the axial direction of A shape internal mold, thereby adapts to different tube diameters and wall thickness, highly versatile.3, the present invention is provided with protection sleeve in the die body periphery, can prevent effectively that abrasive dust from splashing, and reduces dust, improves security.4, axial limiting mechanism of the present invention is spacing, easy to operate simple and direct by the bolt that screws in the sleeve outside.5, the present invention is provided with the electric tool interface according to GB/T 3390.2 standard design in the bottom, directly connects power sub, need not to be equipped with special power set, can realize polishing.

The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
As shown in Figure 1, the present invention includes the plinth 1 of a connection power, be provided with the power interface 11 by GB/T 3390.2 standard design in the bottom of plinth 1, power interface 11 is connected with the power tool of outside.Be provided with a circle groove 12 at the top of power sub seat 1, groove 12 centers are a boss 13.Have the protection sleeve 3 of base 31 around groove 12 by screw 2 connections one, a through hole 32 is offered at base 31 centers, and through hole 32 communicates with groove 12.Bilateral symmetry at through hole 32 is provided with two limited blocks 4, and limited block 4 also is fixed on the base 31 of protection sleeve.Offer a strip through hole 41 on two limited blocks 4 respectively, corresponding with the position of through hole 41, on the sidewall of protection sleeve 3, also offer strip through hole 33.Socket one spring 5 on boss 13, the other end of spring 5 upwards pass through hole 32 backs and are connected with the lower end of die holder 6 in the T shape.The both wings of interior die holder 6 are inserted into respectively in the through hole 41 of two limited blocks 4.From the outside of protection sleeve 3, have the bolt 7 of wing nut respectively by strip through hole 33 screw-ins one, bolt 7 passes through hole 41 and spins with interior die holder 6, screws in the back wing nut and is stuck on the outer wall of protection sleeve 3.The top of interior die holder 6 fixedly installs an A shape internal mold 8, and the inclined upper surface of A shape internal mold 8 is provided with polishing emery stick 9.Like this; A shape internal mold 8 just can move on the axial limiting mechanism that two limited blocks 4, spring 5, interior die holder 6, bolt 7 constitute, and after A shape internal mold 8 moves to desired location, tights a bolt 7 from the outside; just wing nut can be snapped on the protection sleeve 3, die holder 6 is fixing in the axial direction in making.
As Fig. 2, shown in Figure 3, be decussation with A shape internal mold 8 the one V-arrangement external mold of being made up of two-half die 10 is set, the V-arrangement inner surface of V-arrangement external mold 10 also is provided with polishing emery stick 9.V-arrangement external mold 10 bottoms are fixed on the base 31 of protection sleeve 3 by two exterior mold halves seat 14.
As shown in Figure 4, in the foregoing description, base 31 and protection sleeve 3 can split productions, connect by screw 15, can make things convenient for the dismounting and the maintenance of an interior die body like this.
In the foregoing description, limited block 4 all can be welded on the base 31 of protection sleeve with outer mould base 14.A shape internal mold 8 all can be one-body molded with interior die holder 6, V-arrangement external mold 10 and outer mould base 14.
In the foregoing description, can A shape internal mold 8 and V-arrangement external mold 10 be carried out the seriation design, to adapt to the needs of different tubing according to processed tubing model sequence.
As shown in Figure 5, when the present invention works, after connecting power tool by power sub seat 1, be sent to the incision of tubing, utilize A shape internal mold 8 under the spring force effect, axially to move, make the bore and the wall thickness of A shape internal mold 8 and V-arrangement external mold 10 self-adapting tubes, A shape internal mold 8 contacts with mouth of pipe inboard, and V-arrangement external mold 10 contacts with the mouth of pipe outside.After A shape internal mold 8 position was in the axial direction determined, the wing nut on the clamping screw 7 just can make internal mold seat 6 axial restraints, and A shape internal mold 8 is fixing thereupon.Start power tool then, the present invention is rotated with the output of power instrument, A shape internal mold 8 will be polished to the inside and outside mouth of pipe of tubing respectively with the polishing emery stick 9 on the V-arrangement external mold 10.
