Description

Pipe fittings inside and outside trimming tools

The invention relates to the technical field of a hand tool, in particular to a trimming tool inside and outside the pipe.

Generally, the machining position of the workpiece, such as the edge of a round hole or the edge of an object, often produces burrs. Traditionally, burrs have been used to remove burrs. However, for round holes or the inside of the pipe, the size, length and direction of the boring tool may result in inconvenient operation and poor burr removal.

A trimming knife system is known in which a body is coupled to a blade. The user can hold the seat and operate the blade in a scraping manner to remove the burrs from the edge of the workpiece. However, this type of trimming knife is not suitable for the trimming of the edge of the round hole because the blade does not easily protrude into the inside of the round hole and the angle inside the round hole is not good. Next, another trimming knife structure is coupled to a body at one end of a rod. The blade body has a curved bar shape and one side is a blade portion. Since the cutter body is in the shape of a curved bar, the cutter body can appropriately remove the burrs from the edge of the work or the edge of the hole.

However, no matter which of the above-mentioned trimming knives provide only a single function, for example, only to remove the inner diameter burr, an additional trimming tool is required for different usage conditions, such as removing the burrs of the outer edge of the port of the tubular member.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a trimming tool that does not provide the disadvantage of being able to trim the inner edge burrs and outer diameter edge burrs.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a tubular trimming tool which has the dual function of removing the burrs of the inner diameter edge and the burrs of the outer diameter edge.

It is an object of the present invention to provide a pipe trimming tool that can be used with a power tool to achieve quick and labor-saving deburring.

In order to achieve the above object and effect, the trimming tool of the present invention comprises a body having a first end and a second end, and an accommodating space is formed in the axial inner portion of the body to connect the first end; The trimmer is movably disposed in the accommodating space of the body; an outer trimmer is disposed at the second end of the body; a positioning mechanism is disposed on the body and connected to the inner trimmer for The inner trimmer is fixed while the inner trimmer is extended and hidden from the body.

The following is a description of the preferred embodiments of the present invention in accordance with the purpose of the invention.

Referring to FIG. 1, the trimming tool includes a combination of a body 10, an inner trimmer 20, an outer trimmer 30, and a positioning mechanism 40. The inner trimmer 20 and the outer trimmer 30 are disposed at two ends of the body 10. The positioning mechanism 40 is disposed on the outer surface of the body 10.

Referring to FIG. 2 , the body 10 has a rod-shaped configuration having a first end 12 , a second end 14 opposite to the first end 12 , and an accommodating space 16 formed in an axially inner portion of the body 10 . One end of the accommodating space 16 is connected to the first end 12 .

The inner edger 20 has a blade portion 22 at one end thereof, and a positioning hole 24 is formed in the radial direction of the inner edger 20. The inner trimmer 20 is movably disposed in the accommodating space 16 of the body 10.

The outer trimmer 30 is of a cylindrical configuration and can be attached to the second end 14 of the body 10 by a locking means. In particular, the outer trimmer 30 has a tapered insert 32 in the axial direction, and a plurality of scrapers 34 are obliquely fixed in the tapered insert 32.

The positioning mechanism 40 includes a sliding slot 42 and a positioning bolt 44. The sliding slot 42 is formed by a long slot and is formed in the axial direction of the body 10 to communicate with the receiving space 16 . One end of the positioning bolt 44 is used to pass through the sliding slot 42. The positioning mechanism 40 further includes a first recess 46 and a second recess 48. The first recess 46 is formed at one end of the sliding slot 42 and is located on the surface of the body 10. The second recess 48 is formed at the other end of the sliding slot 42 and is located on the surface of the body 10.

Referring to FIGS. 3 and 4, one end of the positioning bolt 44 passes through the sliding slot 42 for locking the positioning hole 24 on the surface of the inner edger 20. The inner edge trimmer 20 is hidden in the accommodating space 16 inside the body 10. The positioning bolt 44 can be rotated to fall into the second recess 48. In particular, the positioning bolt 44 has a retaining edge 49 for Falling into the second recess 48 prevents the inner edger 20 from being mishandled or maliciously operated to extend out of the body 10.

Referring to Figure 5, loosening the locating bolt 44 causes the rim 49 to exit the second recess 48. The combination of the positioning bolt 44 and the inner edger 20 is urged toward the first end 12 of the body 10, and the blade portion 22 of the inner edger 20 can protrude from the first end 12. Then tightening the positioning bolt 44 can cause the blocking portion 39 to fall into the first recess 46, so that the inner trimmer 20 can not only obtain a positioning effect, and during the working, the inner trimmer 20 It does not retract to the inside of the body 10 due to the resistance generated by the trimming action.

Referring to Fig. 6, the inner edger 20 of the present invention can extend into the interior of a tubular member 50 and use the blade portion 22 to flatten or remove the burrs of the inner edge of the port of the tubular member 50. In addition, the outer trimmer 30 is used such that one end of the tubular member 52 projects into the outer trimmer 30, and the outer edge of the port of the tubular member 52 is flattened or burred by each of the scrapers 34. The inner trimmer 20 and the tubular member 50, the outer trimmer 30 and the tubular member 52 can be flattened or burred by relative rotation.

Referring to FIG. 7, the present invention further includes a locking tool head 54, and one end of the inner trimming tool 20 has a first locking hole 26. One end of the locking tool head 54 can be locked to the first locking hole 26 . Referring to FIG. 8 , one end of the outer trimming tool 30 has a second locking hole 36 , and one end of the locking tool head 54 can be locked to the second locking hole 36 .

Referring to FIG. 9, the combination of the inner edger 20 and the locking tool head 54 allows the locking tool head 54 to be mated to a power tool 56. Thus the power tool 56 can drive the inner edger 20 to provide a faster and less laborious trimming effect.

Similarly, the combination of the outer trimmer 30 and the locking tool head 54 can also be coupled to the power tool 56, thereby achieving a faster and less laborious trimming effect.

The above embodiments are merely illustrative of the technology of the present invention and its effects, and are not intended to limit the present invention. Any person skilled in the art can modify and change the above embodiments without departing from the technical spirit and spirit of the present invention. Therefore, the scope of protection of the present invention should be as listed in the patent application scope mentioned later. .
