Description

Technical Field

[0001] The invention belongs to the technical field of hardware tools, and in particular relates to a curved surface deformation file. Background Art

[0002] In the metal, wood or plastic processing industries, the high frequency use of flat files has become one of the keys to the development of these industries. Therefore, optimizing the innovative design of flat files and improving the comfort and efficiency of employees have become the key tasks in this industry.

[0003] File - Flat file is a common metal processing tool with a wide range of applications. It is suitable for industries such as fine processing and surface treatment, such as processing metal, wood, plastic and other industries. It is made of carbon tool steel and is divided into coarse files (4-12 teeth), fine files (13-24 teeth) and smooth files (30-40 teeth) according to the number of teeth on each 10mm long file surface.

[0004] At present, the filing surface of general flat files is flat, and the flat filing surface can be used to file flat objects and small objects well. However, when filing objects with larger curved surfaces, the filing fit rate is low, resulting in a smaller filing area for each action, poor overall flatness of the filing, and low filing efficiency.

[0005] Based on this, the applicant considered designing a curved surface deformation file. Summary of the invention

[0006] In view of the above problems, the present invention provides a curved surface deformation file that overcomes the above problems or at least partially solves the above problems. The technical solution is as follows:

[0007] A curved deformation file comprises a fixed plate, a telescopic mechanism and a file plate, wherein there are multiple telescopic mechanisms, and the multiple telescopic mechanisms are connected side by side on the bottom surface of the fixed plate along the width direction of the fixed plate; there are multiple file plates, and the multiple file plates are connected and arranged one by one at the bottom of the multiple telescopic mechanisms; the length direction of each file plate is consistent with the length direction of the fixed plate; the middle part of each file plate in the width direction is hinged to the bottom of the corresponding telescopic mechanism, and each file plate can rotate around the hinge point between the file plate and the corresponding telescopic mechanism in the width direction; two adjacent file plates are hinged through their two opposite sides in the width direction.

[0008] Compared with the prior art, the curved surface deformation file of the present invention has the following advantages:

[0009] By setting the fixed plate, telescopic mechanism and file plate, multiple file plates can move upward to change their height position under the action of bottom pressure. Since each file plate is subjected to different pressure and is located at a different position, the deflection angles of different file plates can be changed under the action of mutual hinge to adapt to the external curved surface of the object during filing, thereby improving the filing fit rate, increasing the filing contact area of ​​each action, and improving the filing efficiency.

[0010] The above-mentioned curved surface deformation file has the advantages of simple structure and easy implementation, is suitable for installation and use in existing filing work, and has low cost of use, which can improve benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] By setting the fixed plate 100, the telescopic mechanism and the file plates, the multiple file plates can move upward to change their height positions under the action of the bottom pressure. Since each file plate is subjected to different pressures and is located at a different position, the deflection angles of different file plates can be changed under the action of mutual hinge connection to adapt to the external curved surface of the object during filing, thereby improving the filing fit rate, increasing the filing contact area of ​​each action, and improving the filing efficiency.

[0027] The above-mentioned curved surface deformation file has the advantages of simple structure and easy implementation, is suitable for installation and use in existing filing work, and has low cost of use, which can improve benefits.

[0028] In this embodiment, Figure 1-6 As shown, the telescopic mechanism includes a fixed rod 210 and a telescopic rod 220, the fixed rod 210 is vertically fixed to the bottom surface of the fixed plate 100, the telescopic rod 220 is provided with a sliding cavity, and can be slid up and down on the fixed rod 210 through the sliding cavity, a first spring 230 is provided in the sliding cavity, one end of the first spring 230 is connected to the bottom surface of the sliding cavity, and the other end is connected to the fixed rod 210, a hinge rod 240 is provided at the bottom of the telescopic rod 220, and the middle part of the file plate in the width direction is hinged to the bottom end of the hinge rod 240.

[0029] In this way, by providing the fixed rod 210 and the telescopic rod 220, the file plate can be moved up and down by the telescopic rod 220 to change the relative position of the file plate during filing, adapt to different thicknesses on the curved surface, and increase the filing contact area.

[0030] During implementation, the first spring 230 is a compression spring.

[0031] In this embodiment, Figure 1-6As shown, the file plate includes a transition plate 310 and a hinge joint 320. The transition plate 310 includes two side portions opposite to each other in the width direction. There are two hinge joints 320. The two hinge joints 320 are arranged opposite to each other and are respectively installed on the two side portions. An elastic mechanism is provided between each hinge joint 320 and the corresponding transition plate 310. Each hinge joint 320 can be telescopically slid along the width direction of the transition plate 310 through the elastic mechanism.

[0033] In this way, by providing the transition plate 310 and the hinge joint 320, the adjacent file plates can change their lengths through the elastic mechanism when changing their angles, so as to avoid length interference caused by the angle change.

[0040] In this embodiment, Figure 1-6 As shown, it also includes a first clamping bolt 420. A first screw hole is opened on the top surface of the locking cover plate 410. The first clamping bolt 420 can be vertically screwed into the first screw hole to apply a vertical locking force to the fixing plate 100 embedded in the embedding cavity.

[0041] In this way, the first clamping bolt 420 is provided to vertically lock the fixing plate 100 embedded in the embedding cavity, thereby further improving the vertical filing stability, with a simple structure and low cost.

The second clamping bolt 430 can be screwed into the second screw hole laterally to apply a lateral locking force to the fixing plate 100 embedded in the embedding cavity.

[0043] In this way, the second clamping bolt 430 is provided to laterally lock the fixing plate 100 embedded in the embedding cavity, thereby further improving the lateral filing stability, with a simple structure and low cost.
