Description

A kind of coaxitron shovel muscle cutter structure

Technical field

The utility model is related to shovel muscle device, specifically a kind of coaxitron shovels muscle cutter structure.

Background technology

Currently, muscle is removed with lathe process in coaxitron on pipeline, need tubing clamp using lathe tool on lathe Coaxial pipe orifice muscle is removed in boring, and when operation has a large amount of aluminium skimmings greasy residues to influence follow-up line clear in coaxitron inner tube Degree, interior muscle boring are difficult to remove to repair hair and need the plenty of time except part burr, and lathe speed and inefficiency influence working efficiency.

Utility model content

Based on the above issues, the utility model implementation discloses a kind of coaxitron shovel muscle cutter structure, increases shovel muscle knife The applicability of tool, it is time saving and energy saving.

The utility model is to solve above-mentioned technical problem by following technical proposals：

A kind of coaxitron shovel muscle cutter structure, which is characterized in that it includes guiding axis, and the front end socket of the guiding axis is led To head, the rear portion of guide head protrusion is uniformly distributed equipped with several guide pads, is formed and is oriented between adjacent two guide pad Slot, the middle part socket Chan Jin mechanisms of the guiding axis, Chan Jin mechanisms shape are a cylinder, the rear ends of the Chan Jin mechanisms to Outer uniformly protrusion forms limiting stand, and equidistantly uniform hollow out forms several shovel muscle pieces, adjacent two institute for the front end of the Chan Jin mechanisms Muscle cutting edge is shoveled in formation between stating shovel muscle piece, and the rear end of the guiding axis is socketed tool apron.

Further, the rear end that guide head is extended beyond on the outside of the guide pad rear end is arranged, after the guide pad The setting that turns forward from outside to inside is held, the inside of the guide pad rear end is flushed with the rear end of guide head.

Further, the outside of the shovel muscle piece front end is flushed with the front end of Chan Jin mechanisms, the front end for shoveling muscle piece by The outer setting that turns forward in.

The positive effect of the utility model is：Inner tube is totally remained without aluminium skimmings after floating screed, and efficiency is than endoporus boring muscle It is significantly improved；It can realize noresidue at endoporus chip breaking after removing muscle, it is firm in structure light, easy to operate；Cutter head energy quick-replaceable, knife Simple, small, the movable convenience of header structure.

Specific implementation mode

With reference to embodiment and attached drawing, the utility model is described in further detail, but the reality of the utility model The mode of applying is not limited only to this.

The utility model is intended to provide a kind of coaxitron shovel muscle cutter structure, which is characterized in that as shown in Figure 1, it includes The front end of guiding axis 1, the guiding axis 1 is socketed guide head 2, and the rear portion protrusion of the guide head 2 is uniformly distributed leads equipped with several To block 3, guide groove 4, the middle part socket Chan Jin mechanisms 5 of the guiding axis 1, the shovel are formed between adjacent two guide pad 3 5 shape of muscle mechanism is a cylinder, and uniformly protrusion forms limiting stand 6 outward for the rear end of the Chan Jin mechanisms 5, when Chan Jin mechanisms 5 insert When entering to reach in pipeline certain depth, pipeline outer rim resists limiting stand 6, and limitation Chan Jin mechanisms 5 continue movable range forward, institute Equidistantly uniform hollow out forms several shovel muscle pieces 7 for the front end of Shu Chan muscle mechanism 5, and shovel muscle is formed between the adjacent two shovel muscle piece 7 The rear end of cutting edge 8, the guiding axis 1 is socketed tool apron 9.

When it is implemented, extending beyond the rear end setting of guide head 2, the guide pad 3 on the outside of 3 rear end of the guide pad Rear end turn forward from outside to inside setting, the inside of 3 rear end of the guide pad is flushed with the rear end of guide head 2.

When it is implemented, the outside of 7 front end of shovel muscle piece is flushed with the front end of Chan Jin mechanisms 5, before the shovel muscle piece 7 Hold the setting that turns forward from outside to inside, the angle of inclination at the angle of inclination and direction and 3 rear end of guide pad of 7 front end of shovel muscle piece Consistent with direction, the symmetric design of the shovel muscle piece 7 and 3 sides adjacent of guide pad makes the process resistance smaller for shoveling muscle, shovel muscle behaviour Make more smooth.

When it is implemented, using shovel muscle rotary-cut principle, aluminum pipe is gripped, by knife group be put in equipment starting device to It is pushed forward into Chan Jin mechanisms 5, in guiding insertion tube of the Chan Jin mechanisms 5 along muscle in coaxitron, shovel muscle piece 7 rushes in pipeline first will be coaxial Muscle scoops up in pipe, and when muscle shovel is to drawing requirement size in coaxitron, muscle is revolved in 5 rotary-cut of Chan Jin mechanisms to break, and exits shovel muscle cutting edge 8, the coaxitron muscle under shovel is poured out, operation is recycled.

It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined Assert that the utility model specific implementation is confined to these above-mentioned explanations.For the common skill of the utility model technical field For art personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, all should It is considered as belonging to the scope of protection of the utility model.
