Description
Technical field
The utility model belongs to field of machining, specifically, relates 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 of surface of the work is processed.The straight motion of file is the key of filing workpiece when in use, keeping filing.Because the length that workpiece is stretched out at the file two ends is all changing at any time, therefore the pressure size of two hands must make two hand pressures equate the moment of workpiece centre along with length variations, thereby makes the file at an arbitrary position can both the maintenance level.The method is very high to the control requirement of user's strength size, in practical operation, often is difficult to be up to the standard, thereby greatly reduces filing quality and filing efficient, even cause workpiece to be scrapped; In addition, file commonly used generally is made of cutter hub and handle at present, handle is installed on the tongue end of file, at present common handle profile is generally long egg type or is with fusiform elongated cylinder etc., such handle this in actual applications because front palm directly contacts with the file cutter hub of steel, the phenomenon that palm grinds bubble easily appears, not only user's health damaged, increase labour intensity, and operating efficiency and working effect are had a greatly reduced quality.
Summary of the invention
The purpose of this utility model is: a kind of file is provided, it is provided with surface of the work roughness measurement instrument the cutter hub upper surface, need not to depend on human body itself to the sensation of level, and the cutter hub front end has auxiliary holding body, grip the gesture and facial expression of file front end when protecting preposition work, be convenient to simultaneously the work of balance file.
The technical solution of the utility model is: a kind of file, formed by auxiliary holding body 1 and cutter hub 2, cutter hub 2 upper surfaces are provided with the decussation hole, be fixed with in this cross bore can the measuring workpieces surface smoothness face measuring instrument 9, cutter hub 2 front ends are provided with auxiliary holding body 1, auxiliary holding body 1 is cavity body, by the file placed side, cancave cambered surface 5, arc surface 6 and left and right side form up and down, wherein, screw 4 is arranged on the left and right side, file standing groove 3 is arranged on the file placed side, and jackscrew 10 is complementary with screw 4.
The utility model has the advantages that: this file have can the measuring workpieces surface smoothness face measuring instrument, need not to rely on human body sensory to the assurance of level, effectively promote filing quality and filing efficient; Auxiliary holding body effectively is held in the gesture and facial expression of file front end during protected working, is convenient to simultaneously the work of balance file.

Fig. 1 use view of the present utility model, wherein, 1 is auxiliary holding body, and 2 is cutter hub, and 9 is face measuring instrument, and 10 is jackscrew.
Fig. 2 structural representation of the present utility model, wherein, 3 is the file standing groove, and 4 is screw, and 5 is cancave cambered surface up and down, and 6 is arc surface.
The schematic diagram of Fig. 3 the utility model jackscrew, wherein, 7 is screw rod, 8 is notch.
The specific embodiment
A kind of file is comprised of auxiliary holding body 1 and cutter hub 2.Cutter hub 2 upper surfaces are provided with the decussation hole, be fixed with in this cross bore can the measuring workpieces surface smoothness face measuring instrument 9, cutter hub 2 front ends are provided with auxiliary holding body 1, auxiliary holding body 1 is cavity body, by the file placed side, cancave cambered surface 5, arc surface 6 and left and right side form up and down, wherein, screw 4 are arranged on the left and right side, file standing groove 3 is arranged on the file placed side, and jackscrew 10 is complementary with screw 4.
The front end working portion size coupling of the height of file standing groove 3 and width dimensions and work file.The front end that file standing groove 3 is used for placement work file makes it enter 20 millimeters of sheaths.Screw 4 sizes of auxiliary holding body 1 and jackscrew 10 external screw thread sizes coupling.The cancave cambered surface 5 of auxiliary holding body 1 is shaped as the front end work palm that is adapted at file and places arcwall face.The arc surface 6 of auxiliary holding body 1 grips circular shape for the front end work palm that is adapted at file.Jackscrew 10 is comprised of screw rod 7 and notch 8, and the screw rod 7 of jackscrew 10 is measure-alike with the screw 4 of auxiliary holding body.The notch 8 of jackscrew 10 is of a size of suitable straight screwdriver and puts into the notch size.
When using the utility model, the file front end is put into the file standing groove 3 of auxiliary holding body 1, held out against again the side of file with jackscrew 10, at this moment, can grip on the other hand the file holding end, be held on the file protecting bush on the other hand and process.Then, the file that installs auxiliary holding body is positioned on the workpiece filing face, adjusts the file position, make the bubble in the face measuring instrument 3 be parked in the right-angled intersection point, and in the process of using, can judge whether level of file according to the position of bubble.Because the protection of auxiliary holding body can effectively avoid the file front end to grip the injury of hand, simultaneously, file is moved at parallel plane, is convenient to the work of balance file.
