Description
Technical field
The utility model belongs to field of machining, specifically, is related to a kind of file.
Background technology
File belongs to a kind of common instrument in field of machining, is mainly used in the flatness processing to workpiece surface.In use, the flat motion for keeping file during filing is the key of filing workpiece.Because the length that workpiece is stretched out at file two ends is all changing at any time, therefore the pressure size of two hands must make two hand pressures equal to the torque of workpiece centre with length change, so that file can keep level at an arbitrary position.Control of the method to user's strength size requires very high, in practical operation, is often extremely difficult to level, thus greatly reduces filing quality and filing efficiency, even results in workpiece and scraps；In addition, conventional file is typically made up of cutter hub and handle at present, handle is installed on the tongue end of file, at present common handle contours are generally long egg type or with fusiform elongated cylinder etc., such handle this in actual applications, because preceding palm is directly in contact with the file cutter hub of steel, easily there is the phenomenon that palm grinds bubble, not only the body of user is damaged, increases labor intensity, and operating efficiency and working effect can be made to have a greatly reduced quality.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art there is provided a kind of file, and it is provided with workpiece surface roughness measurement instrument, it need not rely upon sensation of the human body to level in itself, and user can two hands grip, feel preferably, both hands active force is also more concentrated when using.
The technical solution of the utility model is：A kind of file, including the handle and cutter hub being connected, cutter hub upper surface is provided with decussation hole, the face measuring instrument of workpiece surface flatness can be measured by being fixed with the cross bore, cutter hub front end is provided with auxiliary holding body, and handle is located in the middle part of the afterbody tongue end of cutter hub, auxiliary holding body and is provided with arc groove, the left or right of arc groove sets arc bump, and cutter hub two ends are respectively embedded into handle and auxiliary holding body.
The utility model has the advantages that relative to prior art：
(1) face measuring instrument of workpiece surface flatness can be measured by being provided with, without relying on assurance of the human body sensory to level, effectively lifting filing quality and filing efficiency.
(2) two hand grips, are easy to balance file work.The great thenar muscle group of forward and backward palm can contain auxiliary holding body and handle in large area during the file cutting carried out under this grip file pattern, therefore its axial filing Resultant force is concentrated, particularly the cutter hub of file by auxiliary holding body institute every, the large and small thenar muscle group of remote holder palm directly participates in having an effect, palm is eliminated directly to contact with cutter hub, thumb or thumb root, middle finger, nameless finger and file generation frictional resistance and the phenomenon for grinding bubble effectively are being prevented, usage comfort and operating efficiency is effectively improved.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of file.
Fig. 2 is the side view of file.
Embodiment
With reference to embodiment and accompanying drawing, the utility model is described in further detail, but embodiment not limited to this of the present utility model.
A kind of file as shown in Figure 1, including the handle 1 and cutter hub 2 being connected, the upper surface of cutter hub 2 is provided with decussation hole, and the face measuring instrument 4 of workpiece surface flatness can be measured by being fixed with the cross bore, the front end of cutter hub 2 is located at the afterbody tongue end of cutter hub 2 provided with auxiliary holding body 3, handle 1.
The middle part of holding body 3 is aided in be provided with arc groove 3-1, arc groove 3-1 left or right sets arc bump 3-2；Aid in holding body 3, the one end being connected with cutter hub 2 is highly less than the other end.When arc bump 3-2 is located at arc groove 3-1 left end, user holds auxiliary holding body with left hand when file is used, and the thumb and large and small thenar of the left hand palm are close to arc groove and arc bump；When arc bump 3-2 is located at arc groove 3-1 right-hand member, user holds auxiliary holding body with the right hand when file is used, and the thumb and large and small thenar of the right hand palm are close to arc groove and arc bump.
Handle 1 is integral type structure, including the cutter hub linkage section 1-1 and endpiece 1-2 being connected, endpiece 1-2 are waist drum like structure, and cutter hub linkage section 1-1 and endpiece 1-2 junction forms the recessed round 1-3 of arcuation that convenient use person holds.File using the right hand in use, when user's left hand holds auxiliary holding body 3, then hold handle 1, the finger tip of the right hand five is forward, thumb is in upper micro- side, and four fingers make the large and small thenar of palm accommodate handle cutter hub linkage section 1-1 and endpiece 1-2 the junctions recessed round 1-3 surfaces of arcuation under；When user's right hand holds auxiliary holding body 3, then handle 1 is held using left hand, it is identical with the hold of the above-mentioned right hand that it holds method.
The through hole 1-4 for facilitating file to stack collection is additionally provided with the endpiece 1-2 of handle 1.
The two ends of cutter hub 2 are respectively embedded into handle 1 and auxiliary holding body 3 is fixedly connected.
Handle 1 and the material of auxiliary holding body 3 are plastics or rubber, and its feel is more preferable when using file.
When using, the hand of user two holds handle 1 and auxiliary holding body 3 respectively, and file is positioned on workpiece filing face, adjustment file position, the bubble in face measuring instrument 3 is parked in right-angled intersection point, and judged according to the position of bubble during use file whether level.
As described above, just can preferably realize the utility model, above-described embodiment is only preferred embodiment of the present utility model, not for limiting practical range of the present utility model；I.e. all impartial changes made according to the utility model content and modification, are all covered by the utility model claim scope claimed.
