Description

Technical Field

[0001] This utility model relates to the technical field of track saws, and in particular to a track structure for the base plate of a track saw. Background Technology

[0002] A rail saw is a common cutting tool, often used for cutting materials such as wood and metal. Existing rail saws typically require the operator to manually push the saw body along the rail to feed the material during the cutting process. For example, patent publication number "CN221754893U" discloses a rail saw that cuts using a manual feed method.

[0003] A rail saw includes a rail and a rail saw body that slides on the rail. The bottom of the rail saw body has a base plate that slides with the rail. For example, the rail has a protrusion, and the base plate has a rail groove for the protrusion to be inserted into and slide with the protrusion. However, due to the machining error between the rail protrusion and the base plate rail groove, it cannot be guaranteed that the accuracy of the rail groove and the rail protrusion will be perfectly matched when each bottom is installed on the rail. If the width of the rail groove is too large, the rail saw is prone to shaking when sliding along the length of the rail, thus affecting the cutting accuracy of the workpiece. Summary of the Invention

[0004] The purpose of this utility model is to provide a base plate track structure for a track saw, in which the rotating knob can adjust the position of the first rotating unit and the distance between the second rotating unit, thereby overcoming the problem of track wobbling when the track saw slides due to track protrusions or base plate track grooves caused by processing errors.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a base plate track structure for a track saw, including a base plate with a track groove. A first roller group is provided at the first end of the base plate corresponding to the track groove, and a second roller group is provided at the second end of the base plate corresponding to the track groove. The first roller group includes a plurality of first rotating units arranged at intervals along the length of the track groove. The first rotating units are rotatably mounted on the base plate and partially extend into the track groove area. The second roller group includes a plurality of second rotating units arranged at intervals along the length of the track groove. The second rotating unit includes an eccentric shaft rotatably connected to the base plate and a second rotating component rotatably connected to the eccentric shaft. The eccentric shaft is provided with a knob, and a rotation damping component is provided between the knob and the base plate. By rotating the knob, the distance of the second rotating component extending into the track groove area is adjusted, thereby adjusting the distance between the first rotating unit and the second rotating unit.

[0006] Furthermore, the first rotating unit includes a fixed shaft fixedly mounted on the base plate and a first rotating component rotatably connected to the outer periphery of the fixed shaft.

[0007] Furthermore, the first rotating component and the second rotating component are bearing components.

[0008] Furthermore, the base plate is provided with a mounting post, and the center of the mounting post is provided with a central channel for the eccentric shaft to pass through. The rotation damping component is press-fitted between the end face of the mounting post and the knob part.

[0009] Furthermore, the rotational damping element is a rubber ring or a silicone ring.

[0010] Furthermore, the base plate and the second rotating unit are provided with a limiting structure for limiting the rotation angle of the knob. The limiting structure includes a limiting block disposed on the knob part and a limiting groove disposed on the base plate. The limiting block is inserted into the limiting groove and can rotate along the limiting groove. The limiting block limits the rotation angle of the knob part by cooperating with the end face of the limiting groove.

[0011] Furthermore, the positions of the first rotating unit and the second rotating unit are correspondingly arranged so that the rotating knob can adjust the distance of the second rotating member extending into the track groove area, thereby adjusting the distance between the first rotating unit and the second rotating unit.

[0012] In summary, this utility model has the following beneficial effects: The bottom plate track structure of this utility model of the track saw has a rotating knob that can adjust the distance between the first rotating unit and the second rotating unit, thereby overcoming the problem of track wobbling when the track saw slides due to track protrusions or base plate track grooves caused by processing errors.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] like Figures 1-6 As shown, a track saw base plate track structure includes a base plate 10 with a track groove 11. A first roller assembly 20 is provided at the first end of the base plate 10 corresponding to the track groove 11, and a second roller assembly 30 is provided at the second end of the base plate 10 corresponding to the track groove 11. The first roller assembly 20 includes a plurality of first rotating units 21 spaced apart along the length of the track groove 11. The first rotating units 21 are rotatably mounted on the base plate 10, and a portion of the first rotating units 21 extends into the area of ​​the track groove 11. The second roller assembly 30 includes a plurality of second rotating units 31 spaced apart along the length of the track groove 11. The second rotating units 31 include... An eccentric shaft 311 is rotatably connected to the base plate 10, and a second rotating member 312 is rotatably connected to the eccentric shaft 311. The eccentric shaft 311 is provided with a knob part 313, and a rotation damping member 314 is provided between the knob part 313 and the base plate 10. By rotating the knob part 313, the distance of the second rotating member 312 extending into the area of ​​the track groove 11 can be adjusted, thereby adjusting the position of the first rotating unit 21 and the distance between the second rotating unit 31. By fine-tuning the distance between the first rotating unit 21 and the second rotating unit 31, the problem of track protrusion or machining error of the track groove 11 of the base plate 10 can be overcome, thereby solving the problem of shaking during sliding.

[0024] In some embodiments, the first rotating unit 21 includes a fixed shaft 211 fixedly mounted on the base plate 10 and a first rotating member 212 rotatably connected to the outer periphery of the fixed shaft 211. When the base plate 10 moves along the length direction of the track, the first rotating member 212 will rotate relative to the fixed shaft 211, and similarly the second rotating member 312 will rotate relative to the eccentric shaft 311.

[0025] In some embodiments, the first rotating member 212 and the second rotating member 312 are bearing members. Compared with the prior art, the sliding friction between the track and the base plate 10 and the track groove 11 is changed to rolling friction through the protrusion, thereby reducing the friction force.

[0026] In some embodiments, the base plate 10 is provided with a mounting post 12, and the center of the mounting post 12 has a central channel for the eccentric shaft 311 to pass through. A rotation damping element 314 is press-fitted between the end face of the mounting post 12 and the knob portion 313. Further, the rotation damping element 314 is a rubber ring or a silicone ring. The function of the rotation damping element 314 is to increase the rotational damping of the eccentric shaft 311, that is, when the eccentric shaft 311 needs to be rotated, a larger force needs to be provided to prevent the eccentric shaft 311 from rotating with the second rotating element 312 under the action of the second rotating element 312.

[0027] In some embodiments, the base plate 10 and the second rotating unit 31 are provided with a limiting structure 40 for limiting the rotation angle of the knob. The limiting structure 40 includes a limiting block 41 disposed on the knob part 313 and a limiting groove 42 disposed on the base plate 10. The limiting block 41 is inserted into the limiting groove 42 and can rotate along the limiting groove 42. The limiting block 41 limits the rotation angle of the knob part 313 by cooperating with the end face of the limiting groove 42. Through this setting, the rotation angle range of the knob part 313 is limited.

[0028] In some embodiments, the positions of the first rotating unit 21 and the second rotating unit 31 are arranged correspondingly, so that the rotating knob 313 can adjust the distance of the second rotating member 312 extending into the area of ​​the track groove 11, thereby adjusting the distance between the first rotating unit 21 and the second rotating unit 31.

[0029] In summary, this utility model has the following beneficial effects: The track structure of the base plate 10 of the track saw of this utility model has a rotating knob 313 that can adjust the distance between the first rotating unit 21 and the second rotating unit 31, thereby overcoming the problem of track protrusion or track groove 11 of the base plate 10 causing the track saw to wobble when sliding due to processing errors.

[0030] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
