Description

Technical Field

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

[0002] Currently, rail saws rely on detachable rail components to guide the cutting path. Generally, the length of a single rail component is sufficient to cover common sheet sizes, and the rail component length must be within a suitable range to ensure straightness requirements. However, when processing needs exceed the range of a single rail component, such as when dealing with extra-long sheets, two rail components must be connected end-to-end to extend the overall length. In existing technology, two rail components need to be joined using a dedicated butt joint connector, which typically uses fasteners to connect to pre-set connection holes on each rail component. However, due to potential minor dimensional or positional tolerances in the connection holes themselves, and the possibility of deformation within the rail components, the two rail components are prone to unevenness after joining. This can cause the rail saw to jam when it reaches the joint, affecting the flatness of the cut surface. Utility Model Content

The first adjustment structure 200 can drive the two track components 100 to align in the height direction, and the second adjustment structure 300 can drive the two track components 100 to align in the width direction. When the two track components 100 are connected, the first adjustment structure 200 can drive and cooperate with the two first adjustment grooves 110 to align the two track components 100 in the height direction, while the second adjustment structure 300 can drive and cooperate with the two second adjustment grooves 120 to align the two track components 100 in the width direction. After aligning the two directions, the two track components 100 can be connected smoothly, which can meet the usage requirements of the track saw.

[0023] Specifically, when docking two track components 100, the first adjusting structure 200 can be first installed in the first adjusting groove 110 of one track component 100, and the second adjusting structure 300 can be installed in the second adjusting groove 120 of the same track component 100. Then, the first adjusting groove 110 and the second adjusting groove 120 of the other track component 100 are docked with the corresponding first adjusting structure 200 and second adjusting structure 300. After docking, the first adjusting structure 200 can be operated. The specific structure of the first adjusting structure 200 is not limited here.

Then, the second adjustment structure 300 can be operated. The specific structure of the second adjustment structure 300 is not limited here. The second adjustment structure 300 can simultaneously cooperate with the two second adjustment grooves 120 and drive the two track pieces 100 to align in the width direction. At this time, after the height and width directions are aligned, the joints of the two track pieces 100 can be aligned, so that the track saw can run smoothly.

[0024] Reference Figure 4In some embodiments of this utility model, the first adjustment structure 200 includes a first mating bar 210 and at least two adjusting studs 220. The first adjustment groove 110 has a first limiting part 111 opposite to its bottom wall. The first mating bar 210 is disposed in the two first adjustment grooves 110. The first mating bar 210 is also provided with a threaded hole 211 that is threadedly connected to each adjusting stud 220. The threaded holes 211 extend along the depth direction of the first adjustment groove 110. The end of one adjusting stud 220 can abut against the bottom wall of one of its first adjustment grooves 110, and the end of the other adjusting stud 220 can abut against the bottom wall of the other first adjustment groove 110, so as to drive the first mating bar 210 to abut against the two first limiting parts 111. Specifically, when two track components 100 are mated, one end of the first mating strip 210 can be inserted into the first adjustment groove 110 of one track component 100, and then the first adjustment groove 110 on the other track component 100 can be fitted onto the first mating strip 210. Then, the ends of the two track components 100 are brought together to connect the two first adjustment grooves 110. After initial alignment, the adjusting studs 220 can be turned for adjustment. It can be understood that the adjusting studs 220 are spaced apart along the extension direction of the first mating strip 210, and each track component 100 has at least one adjusting stud 220. When the adjusting studs 220 are turned, the adjusting studs 220 can move axially along the threaded hole 211. During the alignment process, the adjusting studs 220 can move to abut against the bottom wall of the first adjustment groove 110. After abutting, further turning the adjusting studs 220 can drive the first mating strip 210 to move toward the first limiting part 111. Understandably, when the adjusting studs 220 on both track members 100 are turned, the first mating bar 210 can abut and press against the first limiting part 111 of both track members 100, thereby achieving alignment of the two track members 100 in the height direction. It should be noted that the operator can also turn the adjusting studs 220 for fine adjustments.

[0025] It should be noted that four adjusting studs 220 can be set, with two adjusting studs 220 located at one of the track components 100 and the other two adjusting studs 220 located at another track component 100. By setting the above four adjusting studs 220, both costs can be reduced and precise adjustment can be achieved.

[0026] Reference Figures 5 to 6 In some embodiments of this utility model, both ends of the first mating strip 210 are provided with a first guide portion 212, which is used to guide the first mating strip 210 into the first adjusting groove 110. Specifically, the first guide portion 212 can be configured as a pointed structure with side walls that are inclined inward in the direction towards the outer end, so that the first mating strip 210 can be smoothly inserted into the first adjusting groove 110.

[0027] Reference Figure 4 In some embodiments of this utility model, the adjusting stud 220 includes a stud section 221 and an abutment section 222. The stud section 221 is threadedly connected to the threaded hole 211, and the abutment section 222 can abut against the bottom wall of the adjusting groove. The minimum diameter of the abutment section 222 is greater than the maximum diameter of the stud section 221. Specifically, the abutment section 222 is located at one end of the stud section 221, and the stud section 221 is threadedly engaged with the threaded hole 211. The first mating bar 210 may be provided with a clearance hole for the abutment section 222 to move. The abutment section 222 may be configured as a frustum structure with a larger diameter to increase the area of ​​contact with the bottom wall of the adjusting groove, thereby reducing the pressure on the bottom wall and protecting the track component 100.

[0028] Reference Figures 4 to 6 In some embodiments of this utility model, the second adjustment structure 300 includes a second docking strip 310 and at least two eccentric members 320. The second docking strip 310 is disposed within two second adjustment grooves 120. The eccentric members 320 are rotatably connected to the second docking strip 310, and their rotation axis is parallel to the depth direction of the second adjustment groove 120. The side of one eccentric member 320 can abut against an inner sidewall of one of the second adjustment grooves 120, and the side of the other eccentric member 320 can abut against an inner sidewall of the other second adjustment groove 120, thereby driving the side of the second docking strip 310 to abut against the other inner sidewall of the two second adjustment grooves 120. Specifically, during docking, one end of the second docking strip 310 can be inserted into the second adjustment groove 120 of a track member 100, and then the second adjustment groove 120 of another track member 100 can be fitted onto the other end of the second docking strip 310, and the ends of the two track members 100 abut against each other to achieve preliminary docking. After initial docking, the eccentric component 320 can be rotated for adjustment. When the eccentric component 320 rotates, the eccentric structure can abut against one inner wall of the second adjustment groove 120. When the eccentric component 320 is rotated further, the second docking strip 310 will move in the opposite direction to abut against the other inner wall of the second adjustment groove 120. When the eccentric components 320 on both track components 100 are rotated and engaged, the second docking strip 310 can simultaneously press against the inner walls of the two track components 100 and align them, thereby achieving alignment of the track components 100 in the width direction.

[0029] It is conceivable that four eccentric components 320 can be set, with two located on one track component 100 and the other two located on another track component 100.

[0030] It should be noted that the second adjustment structure 300 can also have other embodiments. For example, the second docking bar 310 can be provided with at least two gear and rack transmission structures. The gears are rotatably disposed on the second docking bar 310, and the racks can abut against the inner sidewall of the second adjustment groove 120. Rotating the gears realizes adjustment.

The eccentric member 320 includes a rotating shaft 321 and an eccentric wheel 322. The rotating shaft 321 is rotatably connected to the connecting hole 312, and the eccentric wheel 322 rotates within the relief groove 311. Specifically, the relief groove 311 allows the eccentric wheel 322 to rotate freely. The eccentric wheel 322 can rotate to protrude from the side wall of the second adjusting strip, thereby achieving lateral transmission and alignment of the track member 100 in the width direction.

[0033] It is conceivable that the eccentric wheel 322 or the shaft 321 may be provided with a mating groove for cooperating with the tool, through which the tool can rotate the eccentric part 320.

[0034] Reference Figures 5 to 6 In some embodiments of this utility model, each end of the second mating strip 310 is provided with a second guide portion 313, which is used to guide the second mating strip 310 into the second adjusting groove 120. Specifically, the second guide portion 313 can be generally designed as a pointed structure to facilitate insertion into the second adjusting groove 120 from the side.

Specifically, both the first adjustment groove 110 and the second adjustment groove 120 can extend to both ends of the track component 100, which facilitates the manufacturing of the track component 100, and both ends of the track component 100 can be connected for easy use.

[0036] Reference Figures 1 to 4In some embodiments of this utility model, the opening orientation of the first adjustment groove 110 is opposite to that of the opening orientation of the second adjustment groove 120. Specifically, the opposite opening orientation of the first adjustment groove 110 and the second adjustment groove 120 facilitates the operator's identification and adjustment, preventing misoperation and resulting adjustment confusion.

[0037] It should be noted that the first adjustment groove 110 and the second adjustment groove 120 mentioned above can be combined into one adjustment groove body, and the first docking strip 210 and the second docking strip 310 can be combined into one docking strip.
