Description

Technical Field

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

[0002] The existing track saw track structure includes: a long base plate, a guide rail on the upper surface of the base plate along its length, and a pressure strip attached to one edge of the lower surface of the base plate, extending along the length. During operation, the track is placed on one side of the workpiece, and then the track saw is installed onto the guide rail on the base plate, allowing the track saw to slide linearly along the guide rail on the base plate, thus enabling a straight cut. The guide rail and pressure strip on the track are correspondingly positioned so that the pressure strip presses against the saw blade during cutting, preventing large burrs from being carried up by the saw blade and resulting in a relatively smooth kerf.

[0003] When connecting existing guide rails, the connecting strips on both sides are first inserted into the strip groove, and then locked in the vertical direction with set screws to make the two guide rails vertically aligned. However, since there is no limit in the left and right directions, the two guide rails will shift in the left and right directions, which will cause the machine to jam or even get stuck when it slides to the connection point. Summary of the Invention

[0004] The purpose of this utility model is to provide a guide rail connection structure for a track saw. By tightening the set screw, the vertical direction of the first guide rail and the second guide rail is limited, and by tightening the eccentric screw, the lateral direction of the first guide rail and the second guide rail is limited. This ensures higher connection accuracy and more stable connection between the first guide rail and the second guide rail, thereby avoiding the problem of jamming when the machine slides.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a guide rail connection structure for a track saw, comprising a first guide rail, a second guide rail, and a connecting strip. The first and second guide rails are provided with interconnected strip grooves. The connecting strip is installed into the strip grooves, with a first end extending to the first guide rail and a second end extending to the second guide rail. The first and second guide rails are provided with opposing first and second limiting portions in the vertical direction. Set screws are respectively connected to the connecting strip in the areas of the first and second guide rails. By tightening the set screws, the set screws extend out of the connecting strip. The connecting strip abuts against the first limiting part, and at the same time, the set screw presses the other end of the connecting strip against the second limiting part to limit the vertical direction of the first guide rail and the second guide rail; the first guide rail and the second guide rail are provided with a third limiting part and a fourth limiting part arranged opposite to each other in the transverse direction, and the connecting strip is connected to an eccentric screw in the area of ​​the first guide rail and the second guide rail respectively. The eccentric screw is provided with an eccentric protruding ring. By turning the eccentric screw, the eccentric protruding ring abuts against the fourth limiting part, and at the same time, the eccentric protruding ring presses the other end of the connecting strip against the third limiting part to limit the transverse direction of the first guide rail and the second guide rail.

[0006] Furthermore, the eccentric screw component is provided with a wave washer and a limiting ring, and the wave washer is disposed between the limiting ring and the connecting strip.

[0007] Furthermore, the connecting strip is provided with two or more sets of eccentric screws in the first guide rail and the second guide rail areas respectively.

[0008] Furthermore, the connecting strip is provided with one or more sets of set screws in the first guide rail and the second guide rail regions respectively.

[0009] Furthermore, the eccentric convex ring and the eccentric screw are integrally formed.

[0010] Furthermore, the first and second guide rails have assembly space on one side corresponding to the second limiting part to facilitate the tightening of the eccentric screw and the set screw.

[0011] Furthermore, the first guide rail and the second guide rail are provided with two sets of horizontally spaced strip grooves, each strip groove is provided with a connecting strip, and each connecting strip is provided with at least one set screw and at least one eccentric screw in the area of ​​the first guide rail and the second guide rail.

[0012] Furthermore, the assembly space of one set of strip grooves is arranged facing upwards, while the assembly space of the other set of strip grooves is arranged facing downwards.

[0013] In summary, this utility model has the following beneficial effects: The guide rail connection structure of this utility model of a track saw, by tightening the set screw so that the set screw extends out of the connecting bar and abuts against the first limiting part, and at the same time the set screw presses the other end of the connecting bar to abut against the second limiting part, thereby limiting the vertical direction of the first guide rail and the second guide rail; then by tightening the eccentric screw so that the eccentric convex ring abuts against the fourth limiting part, and at the same time the eccentric convex ring presses the other end of the connecting bar to abut against the third limiting part, thereby limiting the lateral direction of the first guide rail and the second guide rail, thereby ensuring higher connection accuracy and more stable connection of the first guide rail and the second guide rail, thereby avoiding the problem of jamming when the machine slides.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] 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.

[0024] 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.

[0025] like Figures 1-7 As shown, a rail connection structure for a track saw includes a first rail 10, a second rail 20, and a connecting strip 30, which constitute the basic structure of this utility model.

[0026] The first guide rail 10 and the second guide rail 20 are provided with interconnected strip grooves 11. Specifically, the first guide rail 10 and the second guide rail 20 are respectively provided with strip grooves 11 extending along their length direction. When the first guide rail 10 and the second guide rail 20 are connected, the strip grooves 11 on the first guide rail 10 and the strip grooves 11 on the second guide rail 20 are aligned and interconnected.

[0027] The connecting strip 30 is installed into the strip groove 11, with its first end extending to the first guide rail 10 and its second end extending to the second guide rail 20. The first guide rail 10 and the second guide rail 20 are vertically provided with opposing first limiting portions 12 and 13. Set screws 31 are connected to the connecting strip 30 in the areas of the first guide rail 10 and the second guide rail 20, respectively. By tightening the set screws 31, the set screws 31 extend out of the connecting strip 30 and abut against the first limiting portion 12. Simultaneously, the set screws 31 press the other end of the connecting strip 30 against the second limiting portion 13, thereby adjusting the vertical direction of the first guide rail 10 and the second guide rail 20. The first guide rail 10 and the second guide rail 20 are provided with a third limiting part 14 and a fourth limiting part 15 arranged opposite to each other in the transverse direction. The connecting strip 30 is connected to an eccentric screw 32 in the regions of the first guide rail 10 and the second guide rail 20 respectively. The eccentric screw 32 is provided with an eccentric protruding ring 321. By screwing the eccentric screw 32, the eccentric protruding ring 321 abuts against the fourth limiting part 15. At the same time, the eccentric protruding ring 321 squeezes the other end of the connecting strip 30 to abut against the third limiting part 14, so as to limit the transverse direction of the first guide rail 10 and the second guide rail 20. It should be noted that the transverse direction in this application refers to the width direction of the first guide rail 10 and the second guide rail 20.

[0028] In some embodiments, the eccentric screw 32 is provided with a wave washer 33 and a limiting ring 34. The wave washer 33 is disposed between the limiting ring 34 and the connecting strip 30. The limiting ring 34 is threadedly connected to the set screw 31. The wave washer 33 generates elastic deformation through a wave-shaped ring structure, increases the contact area, and reduces wear, thereby effectively preventing fasteners such as bolts and nuts from loosening. In other words, it is mainly used to prevent mechanical connections from loosening and to buffer impacts.

[0029] In some embodiments, the connecting bar 30 is provided with two or more sets of eccentric screws 32 in the regions of the first guide rail 10 and the second guide rail 20, respectively. By providing two or more sets of eccentric screws 32, the connection accuracy and connection stability of the first guide rail 10 and the second guide rail 20 can be effectively guaranteed.

[0030] In some embodiments, the connecting strip 30 is provided with one or more sets of set screws 31 in the regions of the first guide rail 10 and the second guide rail 20, for example, two sets of set screws 31 can be provided in the regions of the connecting strip 30 corresponding to the regions of the first guide rail 10 and the second guide rail 20.

[0031] In some embodiments, the eccentric protruding ring 321 and the eccentric screw 32 are integrally formed, but they can also be separate components. However, it is necessary to ensure that the eccentric protruding ring 321 and the eccentric screw 32 can rotate synchronously when connected.

[0032] In some embodiments, the first guide rail 10 and the second guide rail 20 have an assembly space 16 on one side corresponding to the second limiting part 13 to facilitate the screwing of the eccentric screw 32 and the set screw 31. The assembly space 16 facilitates the operator to screw the eccentric screw 32 and the set screw 31, thereby facilitating the assembly and disassembly of the first guide rail 10 and the second guide rail 20.

[0033] In some embodiments, the first guide rail 10 and the second guide rail 20 are provided with two sets of horizontally spaced strip grooves 11. Each strip groove 11 is provided with a connecting strip 30. Each connecting strip 30 is provided with at least one set screw 31 and at least one eccentric screw 32 in the area of ​​the first guide rail 10 and the second guide rail 20. This arrangement can effectively improve the connection accuracy and stability of the first guide rail 10 and the second guide rail 20, thereby making the machine slide more smoothly and stably on the first guide rail 10 and the second guide rail 20.

[0034] In some embodiments, the assembly space 16 of one set of strip grooves 11 is arranged facing upwards, and the assembly space 16 of another set of strip grooves 11 is arranged facing downwards.

[0035] In summary, this utility model has the following beneficial effects: The guide rail connection structure of this utility model of a track saw, by tightening the set screw 31 so that the set screw 31 extends out of the connecting bar 30 and abuts against the first limiting part 12, and at the same time the set screw 31 presses the other end of the connecting bar 30 to abut against the second limiting part 13, thereby limiting the vertical direction of the first guide rail 10 and the second guide rail 20; then by tightening the eccentric screw 32 so that the eccentric protrusion 321 abuts against the fourth limiting part 15, and at the same time the eccentric protrusion 321 presses the other end of the connecting bar 30 to abut against the third limiting part 14, thereby limiting the lateral direction of the first guide rail 10 and the second guide rail 20, thereby ensuring higher connection accuracy and more stable connection of the first guide rail 10 and the second guide rail 20, thereby avoiding the problem of jamming when the machine slides.
