Description

Manual file device of high accuracy

Technical Field

The utility model belongs to the technical field of the machine-building processing, concretely relates to manual file of high accuracy cuts device.

Background

In the machining manufacturing process, filing of a workpiece is a very necessary process, such as machining steps of fitting the workpiece, deburring, improving surface finish, correcting dimensions of parts, and the like. The common tool for manual filing at the present stage is a flat file, which has only one handle installed at the rear side of the file in a straight line with the file. Filing with a flat file has the following problems:

1) the flat-shaped file does not conform to ergonomics: the file is arranged above a workpiece, and then the workpiece is pushed forwards through arms at two sides to complete the file action on the workpiece.

2) The operation precision is not easy to guarantee: high-precision manual filing is an operation process with high technical requirements, and only a few techniques can be sufficient. The file is held by two hands and applies proper acting force to the part, the two hands are controlled to be kept at the same horizontal height, only depending on experience and feeling of an operator, when a workpiece is positioned at the front side and the rear side of the file, the horizontal height of the two hands is difficult to control due to the fact that the two hands apply downward acting force, the situation that the heights of the two hands are not consistent easily occurs, once the heights of the two hands are not horizontal, the precision of the workpiece cannot be guaranteed, and even the workpiece can be scrapped.

3) The processing of larger size workpieces cannot be performed: the flat plate file is integrally a flat plate, only the rear end of the file can be provided with the handle, an operator holds the handle with one hand and the front end of the file with the other hand during operation, the lowest point of the hand and the handle is certainly lower than the tooth surface of the file, the holding positions of the two ends can limit the processing size of the tooth surface of the file, and the flat plate file cannot be processed when the processing size exceeds the front-back holding distance of the file.

Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.

Examples

As shown in fig. 1 to 4, a high-precision manual filing device includes a file body 1, fixing brackets 2 provided at both ends of the file body 1, and a handle 3 rotatably connected to the fixing brackets 2. The file body 1 is provided with an upper tooth surface, a lower tooth surface, a left side surface, a right side surface and two end surfaces, and two screw holes are respectively arranged on the left side surface and the right side surface of each end at two ends of the file body 1. The fixing bracket 2 is a rectangular plate, and the thickness of the rectangular plate is consistent with the distance between the upper tooth surface and the lower tooth surface. The two ends of the rectangular plate are respectively provided with a first groove and a second groove which are all penetrated vertically, the first groove is used for embedding one end of the file body 1, two groove walls of the first groove are respectively provided with a first through hole (not shown) corresponding to the screw hole, and the file body 1 and the fixed support 2 are fixedly connected by inserting the screw 5 into the first through hole and screwing the screw hole. Second through holes (not shown) are respectively formed in two groove walls of the second groove. The handle 3 includes a tubular shaft 31, a sleeve 33 fitted over the tubular shaft 31 and rotatable with respect to the tubular shaft 31, and a gland 34 disposed at one end of the tubular shaft 31, a connecting block 32 connected to the other end of the tubular shaft 31, a third through hole 36 formed in the connecting block 32 and perpendicular to the central axis of the tubular shaft 31, a protruding rod 35 perpendicular to the gland 34 and inserted into the inner cavity of the tubular shaft 31, the sleeve 33 being limited on the tubular shaft 31 between the connecting block 32 and the gland 34, the connecting block 32 being a rectangular block. The connection among the pipe shaft 31, the convex rod 35 and the connecting block 32 is as follows: tubular shaft 31 one end sets up the internal thread, and the other end sets up the external screw thread, sets up the external screw thread on the nose bar 35, and it has the screw to open on the connecting block 32, and the internal thread of tubular shaft 31 one end carries out threaded connection with the external screw thread of nose bar 35, and the external screw thread of the other end of tubular shaft 31 carries out threaded connection with the screw of connecting block 32. The connecting block 32 is embedded into the second groove, a screw is inserted into the second through hole and the third through hole 36 to serve as the rotating shaft 6, and nuts are used at two ends of the screw for limiting, so that the handle 3 rotates relative to the fixed support 2.

The tooth surface of the file body 1, the rotating shaft 6 and the handle 3 form an included angle, and the included angle is changed along with the rotation of the handle 3. Set up a recess respectively on every rectangular plate, set up a bubble spirit level 4 in the recess, the degree of depth that highly is less than the recess of bubble spirit level 4, two spirit levels are not in the homonymy.

When in use, the upper tooth surface or the lower tooth surface of the file body 1 is selected to file a workpiece, two hands are respectively held on the sleeves 33 of the handles 3 with two adjustable sides, and the handle sleeves 33 can rotate on two tube shafts, so that an operator can adjust the angle between the arm and the wrist according to the height of the workpiece to achieve the most comfortable operation posture. The operator can also set the bubble level meter 4 on the fixed bracket 2 at the front end or the rear end of the file according to personal habits and the observation height of filing the workpiece, and make the bubbles in the bubble level meter 4 be located in the middle circle, because the level heights of both hands can be consistent when the bubbles are located in the middle circle, thereby ensuring the processing precision. Because the angle of the handle can be adjusted, the upper tooth surface and the lower tooth surface of the fixed support and the file body are positioned at the same plane height, and the heights of the two hands are certainly higher than the processing tooth surface of the file in the operation process, the processing operation cannot be influenced when the workpiece ruler exceeds the holding distance.

The above-mentioned techniques not specifically mentioned refer to the prior art.

As mentioned above, although the present invention has been shown and described with reference to certain preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
