[0033] To make the objectives and technical solutions of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] like Figure 1 As shown: This utility model discloses a table saw backing auxiliary positioning system. The table saw backing 2 of the table saw 1 is located on one side of the saw blade. The table saw 1 is provided with a backing track for the backing to move. The height and angle of the saw blade are adjusted by the saw blade lifting adjustment handwheel 3 and the saw blade swing angle adjustment handwheel 4 on the table saw.

[0035] A visual recognition component 5 and a fine-tuning displacement mechanism 6 for synchronously adjusting the displacement of the table saw 1 are provided on the table saw backing 2. The fine-tuning displacement mechanism 6 is arranged on the backing track through a spring clamping mechanism 7. The visual recognition component 5 is used to identify and preset the backing movement position.

[0036] The saw blade lifting adjustment handwheel 3 is connected to the shaft of the inclinometer assembly 8. The saw blade swing angle adjustment handwheel 4 will drive the saw blade lifting adjustment handwheel 3 to lift synchronously. The lifting of the saw blade lifting adjustment handwheel 3 will cause the inclinometer assembly 8 to tilt. The inclinometer assembly 8 will provide feedback on the actual tilt angle through the tilt degree.

[0037] The table saw backrest auxiliary positioning system uses digital imaging technology and a fine-tuning displacement mechanism to help the table saw backrest move quickly and accurately to the designated position, improving work efficiency.

[0038] like Figure 2 , Figure 3 , Figure 4 The visual recognition components shown:

[0039] The visual recognition component 5 is fixed to the back of the table saw via the camera housing 52.

[0040] The visual recognition component 5 includes a camera 51, a camera housing 52, a scale 53, and a display screen 54;

[0041] The scale 53 is installed on the underside of the table saw's back rail by the scale rotating seat. The camera 51 is fixedly installed on the outside of one end of the table saw's back rail 2 by the camera housing 52. The scale 53 is located below the back rail, and the camera 51 is installed on the camera housing 52. The camera 51 feeds back the actual distance between the table saw's back rail 2 and the table saw blade to the display screen 54.

[0042] The camera focuses on the scale and images it in real time. Through digital imaging technology, the actual distance between the saw blade and the saw head is displayed on the screen. The scale is available in lengths suitable for extending the table to sizes up to 52 inches.

[0043] The principle behind digital imaging technology is as follows: a camera captures the scale information displayed on the ruler; AI recognizes the scale in the image and converts it into digital information, which is then compared with preset numbers to display and preset the position of the table saw against the mountain; the operation process is as follows:

[0044] (1) Input the preset distance between the backrest and the saw blade via the touch screen;

[0045] (2) Release the locking handle of the BIG EYE straight ruler and quickly move it to the vicinity of the preset position;

[0046] (3) Turn the fine adjustment knob until you hear a "beep beep beep" sound, then slow down the turning speed and stop when you hear a success sound.

[0047] (4) Tighten the BIG EYE straight ruler locking handle, and the backrest will be in the preset position;

[0048] Two auxiliary functions can be achieved using the touchscreen display: camera focus adjustment and position calibration. Camera focus adjustment process: Select the focus adjustment mode on the touchscreen display. The camera will transmit the captured image to the display in real time. Rotate and adjust the camera's position until the displayed image is clear.

[0049] Position calibration process: The large-eye straightedge has its own locking handle. Loosening the locking handle allows you to manually move the entire straightedge and auxiliary positioning mechanism freely. Select the position calibration mode on the touch display, move the straightedge to fit snugly against the saw blade, and you can set this position as 0 point.

[0050] like Figure 5 , Figure 6 The fine-tuning displacement mechanism 6 shown is connected to the side of the BIG EYE ruler by a fine-tuning fixing bracket;

[0051] Includes a fine-tuning housing 61, a fine-tuning knob 62, a rubber roller 63, a first-stage A1 gear 64, a first-stage A2 gear 65, a second-stage B1 gear 66, and a second-stage B2 gear 67;

[0052] The fine-tuning housing 61 is arranged on one side of the table saw's support rail 2, located on the side of the table saw's support rail track; the fine-tuning knob 62 is on the same axis as the first-stage A1 gear 64, the second-stage B1 gear 66 is on the same axis as the first-stage A2 gear 65, the rubber roller 63 is on the same axis as the second-stage B2 gear 67, and the second-stage B1 gear 66 and the second-stage B2 gear 67 mesh with each other;

[0053] The fine-tuning displacement is achieved through a two-stage gear transmission. After the fine-tuning knob is turned, the first-stage A1 gear rotates, driving the first-stage A2 gear to rotate. The second-stage B1 gear then transmits the motion to the second-stage B2 gear. The fine-tuning displacement mechanism 6, driven by the rotation of rubber rollers, moves the entire backrest. The two-stage transmission ratio reduces the rotation of the fine-tuning knob to a tiny displacement of the entire backrest, achieving precise positioning of the backrest.

[0054] like Figure 8 , Figure 9 As shown: The spring clamping mechanism 7 includes a fine-tuning fixing bracket 71, a guide post 72, a spring 73, a guide post connecting block 74, and an adjusting screw 75; the spring clamping mechanism is used to keep the fine-tuning displacement mechanism pressed against the backing guide rail at all times, ensuring that the friction between the rubber roller and the guide rail is sufficient to drive the entire backing to move.

[0055] The fine-tuning fixing bracket 71 is fixed on the outer side of one end of the table saw back (2). The bottom end of the fine-tuning fixing bracket 71 is provided with a guide post connecting block 74. The guide post 72 passes through the guide post connecting block 74 and the fine-tuning fixing bracket 71. The thread on the head of the guide post 72 fixes the guide rod and the fine-tuning fixing bracket 71. The outer half edge of the bottom end face of the fine-tuning fixing bracket 71 is provided with a guide post fixing cavity 76. One end of the guide post 72 is fixed by the internal thread in the guide post fixing cavity 76 through the thread structure. The other end of the guide post 72 is connected to the guide post connecting block 74. The guide post connecting block 74 is used to arrange the threaded hole of the guide post 72 and the screw hole for placing the set screw 77 is arranged horizontally on the through hole. The set screw 77 is fastened to part of the guide post 72.

[0056] The fine-tuning fixing bracket 71 has an inner cavity for accommodating the spring 73 and the adjusting screw 75, with the adjusting screw 75 passing through the guide post connecting block 74.

[0057] The set screw 77 on the rear side of the guide post connecting block 74 presses the guide post 72, fixing the guide post connecting block 74 and the guide post 72 in place, meaning that the guide post and the guide post connecting block do not experience relative displacement. The adjusting screw 75 is threadedly connected to the guide post connecting block 74, and the head of the adjusting screw presses the spring into the fine-tuning fixing bracket 71. The reaction force of the spring 73 will press the adjusting screw down, causing the guide post connecting block 74 to press down, so that the rubber roller of the fine-tuning component is always pressed against the guide rail. By rotating the adjusting screw, the spring can be tightened / loosened, and the spring reaction force will change accordingly, thereby adjusting the above-mentioned clamping force.

[0058] like Figure 10 The inclinometer assembly shown is mounted on the table saw blade lifting and adjusting mechanism. Rotating the saw blade swing angle adjustment handwheel will cause the entire lifting mechanism and saw blade to swing, and the inclinometer will feed back the tilt angle to the display screen.

[0059] Inclinometer assembly 8 includes inclinometer bracket 81, inclinometer support 82, and inclinometer 83;

[0060] One end of the inclinometer bracket has a shaft hole 84 coaxially arranged with the saw blade lifting and adjusting handwheel 3, and the other end of the inclinometer bracket 81 has an inclinometer support 82; the inclinometer 83 is mounted on the inclinometer support 82. Fixing screws lock the entire assembly onto the table saw blade lifting and adjusting mechanism. A cylindrical pin positions the bracket and support. A small oblong hole is provided on the support for fine-tuning the support's inclinometer angle.

[0061] The inclinometer support 82 and the inclinometer 83 are attracted to each other by magnets. A piece of iron is embedded in the bottom of the support, and magnets are installed on the inner side wall of the inclinometer. This allows the inclinometer to be removed at any time or rotated 90° for placement.

[0062] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
