Abstract
Description
Technical Field
[0001] This utility model relates to the field of reciprocating file technology, and in particular to a reciprocating file that can reduce vibration. Background Technology
[0002] A reciprocating file is a handheld polishing tool. Users can hold polishing consumables such as files, whetstones, fiber whetstones, hardwoods, and copper rods in the chuck for processing. Because it moves at high speed back-and-forth or side-to-side with a fixed stroke, the polishing consumables held in the chuck will vibrate to varying degrees with changes in rotation speed. This vibration causes unevenness on the surface of the workpiece being processed, especially when processing workpieces with complex shapes. Therefore, users habitually press the consumable with their fingers, and the amount of finger pressure directly affects work efficiency. Prolonged hand pressure during work can cause muscle tremors in the operator's arms and lead to occupational diseases. To alleviate hand pain caused by fatigue and vibration, a rubber handle for easy gripping should be added to the outside of the file handle.
[0003] Existing reciprocating files with rubber handles have shortcomings in use. First, the rubber handles are mostly fixed, making it difficult to quickly reattach them to the file shaft when damaged. Second, their anti-vibration effect is not ideal. Therefore, the inventor aims to optimize and improve existing reciprocating files with rubber handles. Summary of the Invention
[0004] The purpose of this invention is to overcome the aforementioned problems in traditional technology and provide a reciprocating file that can reduce vibration.
[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A reciprocating file capable of reducing vibration includes a file shank, a file chuck, polishing consumables, a rubber handle, fixed blocks, moving blocks, and compression springs. Polishing consumables are mounted on the front end of the file shank via the file chuck. Two fixed blocks are fixedly mounted on the outer side of the file shank. Moving blocks are slidably mounted on the file shank around each fixed block. Compression springs are symmetrically mounted between the fixed blocks and adjacent moving blocks. The longitudinal cross-sections of the fixed blocks and moving blocks are identical elliptical structures. The rubber handle is sleeved on the outside of the fixed blocks, moving blocks, and compression springs. The rubber handle consists of a central handle portion and side handle portions on either side. Elliptical through-grooves are formed in the side handle portions, and circular movable grooves are formed inside the central handle portion.
[0006] Furthermore, in the aforementioned reciprocating file that can reduce vibration, the polishing consumable is a file, a non-fibrous whetstone, a fibrous whetstone, hardwood, or a copper rod.
[0007] Furthermore, in the aforementioned reciprocating file that can reduce vibration, the shape of the elliptical groove in the side shank matches the longitudinal cross-sectional shape of the stationary / moving block.
[0008] Furthermore, in the aforementioned reciprocating file that can reduce vibration, the diameter of the circular movable groove in the middle shank is greater than or equal to the major axis of the elliptical through groove.
[0009] Furthermore, in the aforementioned reciprocating file that can reduce vibration, the minor axis of the elliptical groove is greater than or equal to the outer diameter of the file shank.
[0010] Furthermore, in the aforementioned reciprocating file that can reduce vibration, the axial length of the circular movable groove is greater than the distance between the two fixed blocks.
[0011] Furthermore, in the aforementioned reciprocating file that can reduce vibration, the file rod, fixed block, and moving block are all made of metal. The fixed block is fixed to the file rod by welding, and the moving block has a sliding hole that facilitates the passage of the file rod.
[0012] Furthermore, in the aforementioned reciprocating file that reduces vibration, the handle is a one-piece structure made of wear-resistant rubber material.
[0013] The beneficial effects of this utility model are: 1. Convenient installation and replacement of the rubber handle: The shape of the elliptical groove in the side handle of the rubber handle matches the longitudinal cross-sectional shape of the fixed block / moving block. This allows the rubber handle to be fitted onto the outside of the fixed block, moving block, and compression spring. Using tools such as push rods, the moving block squeezes the compression spring and enters the circular movable groove. Rotating the rubber handle 90 degrees allows the moving block to abut against the end of the circular movable groove. This method allows for quick installation or replacement of the rubber handle when it is damaged, solving the problem that the rubber handle of existing reciprocating files with rubber handles is a fixed structure and cannot be quickly installed after damage.
[0014] 2. Excellent anti-shake effect: By setting a fixed block and a moving block on the outside of the file bar, and symmetrically installing compression springs between the fixed block and the adjacent moving block, the elasticity of the compression springs is used to reduce the shaking generated when the handle moves back and forth or left and right at high speed, providing the operator with a comfortable grip experience and effectively relieving the operator's hand pain caused by fatigue and vibration.
[0015] 3. Good structural adaptability: The diameter of the circular movable groove in the middle handle is greater than or equal to the major axis of the elliptical through groove, the minor axis of the elliptical through groove is greater than or equal to the outer diameter of the file handle, and the axial length of the circular movable groove is greater than the distance between the two fixed blocks. This allows the rubber handle to be well adapted to the file handle and related components, ensuring the stability of the overall structure and the convenience of use.
[0016] 4. Durable components: The file handle, fixed block, and moving block are all made of metal. The fixed block is fixed to the file handle by welding. The rubber handle is a one-piece structure made of wear-resistant rubber material, which improves the durability of each component and extends the service life of the tool.
[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figures 1-6As shown, this embodiment provides a reciprocating file capable of reducing vibration, including a file rod 1, a file chuck 2, polishing consumables 3, a rubber handle 4, fixed blocks 5, moving blocks 6, and compression springs 7. Polishing consumables 3 are mounted on the front end of the file rod 1 via the file chuck 2. Two fixed blocks are fixedly mounted on the outer side of the file rod 1. Moving blocks 6 are slidably mounted on the file rod 1 around each fixed block 5. Compression springs 7 are symmetrically mounted between the fixed blocks 5 and adjacent moving blocks 6. The longitudinal cross-sections of the fixed blocks 5 and moving blocks 6 are elliptical structures of the same specifications.
[0022] In this embodiment, the tail end of the file rod 1 has a diameter of 5 mm, which facilitates insertion into the machine (pneumatic equipment) for locking.
[0023] In this embodiment, the file chuck has a 3 mm chuck, which can hold various polishing consumables with a diameter of 3 mm.
[0024] In this embodiment, the polishing consumable 3 is a file, a non-fiber oilstone, a fiber oilstone, hardwood, or a copper rod.
[0025] In this embodiment, the rubber handle 4 is sleeved on the outside of the fixed block 5, the moving block 6 and the compression spring 7. The rubber handle 4 is composed of a middle handle portion 401 and side handle portions 402 located on both sides of it. An elliptical through groove 403 is provided in the side handle portion 402, and a circular movable groove 404 is provided inside the middle handle portion 401.
[0026] In this embodiment, the shape of the elliptical groove 403 in the side handle 402 matches the longitudinal cross-sectional shape of the fixed block 5 / moving block 6.
[0027] In this embodiment, the diameter of the circular movable groove 404 in the intermediate handle 401 is greater than or equal to the major axis of the elliptical through groove 403. The minor axis of the elliptical through groove 403 is greater than or equal to the outer diameter of the file handle 1. The axial length of the circular movable groove 404 is greater than the distance between the two fixed blocks 5.
[0028] In this embodiment, the file rod 1, the fixed block 5, and the moving block 6 are all made of metal. The fixed block 5 is fixed to the file rod 1 by welding, and the moving block 6 has a sliding hole that allows the file rod 1 to pass through.
[0029] In this embodiment, the rubber handle 4 is an integral structure made of wear-resistant rubber material.
[0030] The working principle of this embodiment is as follows: A compression spring is symmetrically arranged between the fixed block and the moving block mounted on the outside of the file handle. When the file handle vibrates during movement, the moving block slides on the file handle, and the compression spring undergoes elastic deformation due to the relative movement of the moving and fixed blocks. The elastic restoring force of the compression spring is used to buffer and offset part of the force generated by the vibration, thereby reducing the vibration of the handle. This provides a comfortable grip for the operator and effectively alleviates hand pain caused by fatigue and vibration.
