[0034] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0035] See Figures 1-5 This utility model discloses a material positioning device for a reciprocating saw, including a workbench 10, a ruler 20, a positioning seat 40, and a digital display mechanism. The workbench 10 is provided with a workbench surface 11, and the ruler 20 is set on the workbench surface 11. The ruler 20 is set along the length direction of the workbench 10, and the side of the ruler 20 is provided with a ruler abutment surface 21. The ruler 20 is perpendicular to the workbench surface 11.

[0036] Additionally, a positioning seat 40 is disposed on the worktable surface 11. The positioning seat 40 is disposed along the width direction of the worktable 10, and is slidably connected to the straightedge 20. The positioning seat 40 can also slide along the length direction of the worktable 10. A positioning abutment surface 41 is provided on the side of the positioning seat 40. The positioning abutment surface 41 is perpendicular to the worktable surface 11 and perpendicular to the positioning abutment surface 20.

[0037] The specific digital display mechanism includes a magnetic head, a magnetic strip 31, and a digital display structure. The magnetic strip 31 is set on the ruler 20, and the magnetic head 33 is installed on the positioning seat 40. When the magnetic head 33 slides on the positioning seat 40, it magnetically engages with the magnetic strip 31 and sends a position signal. The digital display structure is used to receive and display the position signal.

[0038] Based on the above structure, when using the material positioning device of the reciprocating saw of this utility model,

[0039] During the wood cutting process, the long side of the wood rests against the straightedge abutment surface 21 of the straightedge 20, and the wide side rests against the positioning abutment surface 41 of the positioning seat 40. The straightedge 20 is used to assist in the positioning of the workpiece and ensure cutting accuracy. The straightedge 20 is set along the length direction of the worktable 10 and can provide a positioning reference for the workpiece in the length direction. The positioning seat 40 is slidably connected to the straightedge 20 and can slide along the length direction of the worktable 10, adapting to the length dimension of the wood.

[0040] In the digital display mechanism, the magnetic strip 31 is mounted on the straightedge 20, and the magnetic head 33 is mounted on the positioning seat 40. When the positioning seat 40 slides, the magnetic head 33 and the magnetic strip 31 magnetically cooperate to generate a position signal. The digital display structure receives and displays this signal, measures the displacement by changing the magnetic signal, and converts it into a digital display. This digital display method can accurately display the position of the positioning seat 40. That is, based on the sliding of the positioning seat 40 along the length direction, it can adapt to the length of the wood for sliding positioning, display the wood length dimension, and improve the positioning accuracy and operation convenience of the workbench 10.

[0041] It should be noted that in related technologies, the magnetic strip 31 is a strip structure formed by uniformly coating a magnetic material (such as iron oxide) onto a plastic substrate. Its surface is divided into multiple magnetic tracks, each of which records binary data through a different magnetization direction. The magnetic head 33 is an electromagnetic conversion device, mainly composed of an iron core and a coil. When the magnetic strip 31 passes over the magnetic head 33, the change in the magnetic field of the magnetic strip 31 induces an electromotive force in the coil, and the data is read by detecting the voltage change. Of course, the data read by the magnetic head 33 and the magnetic strip 31 is prior art and does not fall within the technical content protected by this application, and will not be described in detail here.

[0042] As an optional implementation, the digital display structure includes a display box 321 and a display screen 322. The display box 321 is mounted on the positioning base 40; the display screen 322 is mounted on the display box 321 and receives position signals. Thus, the position signals detected by the magnetic head 33 and the magnetic strip 31 can be received through the display screen 322 for easy observation.

[0043] Furthermore, the display box 321 is rotatably mounted on the positioning base 40 via the pivot 323. This allows the orientation of the display screen 322 to be adjusted by rotating the display box 321, making it convenient for users to observe from different angles and providing greater flexibility in use.

[0044] As an optional implementation, sliding guide mechanisms are provided on both sides of the worktable 10 in the width direction. The sliding guide mechanisms are used to guide the positioning seat 40 to slide, so as to guide the positioning seat 40 to slide stably along the worktable 10 and prevent the positioning seat 40 from swaying during the sliding process.

[0045] As an optional implementation, the sliding guide mechanism includes a slide rail 51 and a slider 53. The worktable 10 is provided with slide rails 51 on both sides, and the positioning seat 40 is provided with sliders 53 on both sides. The sliders 53 slide in cooperation with the slide rails 51.

[0046] When the positioning seat 40 slides relative to the straightedge 20, an external force is applied to the positioning seat 40, and the slider 53 on the positioning seat 40 slides linearly on the slide rail 51 of the worktable 10. The surface of the slide rail 51 is precision machined to provide a smooth moving surface, thereby reducing the frictional resistance when the slider 53 slides. Since sliders 53 are provided on both sides of the positioning seat 40 and slide rails 51 are provided on both sides of the worktable 10, the sliding of both sides of the positioning seat 40 can be guided by the sliders 53 and the slide rails 51, reducing the offset of the positioning seat 40 in the width direction. In this way, when the wood abuts against the positioning abutment surface 41 of the positioning seat 40, the positioning abutment surface 41 will not wobble due to sliding, thus improving the positioning accuracy.

[0047] Of course, lubricant may be added between the slider 53 and the slide rail 51 to further reduce friction and improve the smoothness and efficiency of the movement. This sliding fit allows the positioning seat 40 to move precisely along a specific direction of the worktable 10, thereby realizing functions such as positioning and moving objects.

[0048] As an optional implementation, the sliding guide mechanism also includes a locking element 52, which is mounted on the positioning seat 40 and used to lock the slider 53 and the slide rail 51. In this way, after the positioning seat 40 slides into place, the locking element 52 can lock the slider 53 and the slide rail 51 connected to the positioning seat 40, preventing the positioning seat 40 from sliding during operation and affecting the machining accuracy.

[0049] As an optional implementation, the locking member 52 includes a locking block 521 and a locking screw 522. Specifically, the locking block 521 is provided with two locking arms 523, and a locking groove 524 is formed between the two locking arms 523. The slide rail 51 is slidably engaged with the locking groove 524. The locking screw 522 is screwed to the locking arms 523 and drives the two locking arms 523 to move closer or further apart during the rotation of the screw thread. When the positioning seat 40 slides on the slide rail 51 via the slider 53, the locking screw 522 rotates until the two locking arms 523 move away from each other, and the two locking arms 523 are released. At this time, the slide rail 51 can slide relative to the locking groove 524. The sliding of the positioning seat 40 is guided by the slider 53 and the slide rail 51.

[0050] However, when the positioning seat 40 slides, the locking screw 522 rotates, driving the two locking arms 523 to move closer together and press against the slide rail 51, thus locking them in place. It should be noted that the locking screw 522 is threadedly connected to one of the locking arms 523, and the other locking arm 523 has a threaded hole. This allows the locking screw 522 to be threaded into or released from the threaded hole of the other locking arm 523, achieving locking or unlocking.

[0051] As an optional implementation, the locking screw 522 is provided with a rotating handle, which is used to drive the locking screw 522 to rotate. In this way, the locking screw 522 can be operated by holding the rotating handle, making the operation more convenient.

[0052] As an optional implementation, to facilitate the installation of the slider 53, a first mounting plate 42 and a second mounting plate 43 can be provided on both sides of the positioning base 40. The first mounting plate 42 is connected to the top of the positioning base 40 and extends toward the top of the ruler 20. The slider 53 is provided at the bottom end of the first mounting plate 42. The second mounting plate 43 is connected to the side end of the positioning base 40 and extends downward; the slider 53 is provided on the inner side of the bottom end of the second mounting plate 43.

[0053] Based on this structure, when the positioning seat 40 slides, one side of the positioning seat 40 abuts against the guide surface 21 of the guide ruler 20, and the first mounting plate 42 extends toward the top of the guide ruler 20. In this way, the first mounting plate 42 of the positioning seat 40 slides with the slide rail 51 at the top of the guide ruler 20 through the slider 53 at the bottom. Meanwhile, the second mounting plate 43 on the other side of the positioning seat 40 slides with the other slide rail 51 through the slider 53 on the side. In this way, both sides slide with the slider 53 and the slide rail 51, making the sliding process of the positioning seat 40 more stable.

[0054] As an optional implementation, a base frame 60 is provided at the bottom of the worktable 10. The base frame 60 can evenly distribute the weight of the worktable 10 to the ground, preventing the worktable 10 from tilting or shaking due to uneven force. In this way, the worktable 10 can remain stable during processing, reducing the reduction in processing accuracy due to shaking.

[0055] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
