[0002] Sliding table saw is a kind of mechanical equipment for wood processing, mainly used for straight cutting, and can also be realized by being equipped with appropriate accessories to be inclined or other types of cutting. The core feature of sliding table saw is that a sliding workbench, also called sliding table, is designed, which is perpendicular to the saw blade, and the user can make the wood on the workbench close to the saw blade by pushing, and the cutting action is completed when the saw blade rotates. Sliding table saw usually includes the following main components: sliding table, used to carry and push wood to approach the saw blade; workbench surface, also called material placing rack, which provides a flat surface to place wood; fender: with scale on it, used to set cutting width, ensure cutting accuracy, and make board, wood or wood and other materials keep parallel and close to the fender, so that the material and the saw blade keep fixed angle and prevent displacement; saw blade, rotating saw blade that performs actual cutting work. Sliding table saw is widely used in furniture manufacturing, wood processing and other industries due to its high precision, high efficiency and safety. Compared with traditional handheld circular saw, sliding table saw can cut wood more accurately, while reducing the risk of direct contact with the saw blade for the operator, improving safety.

When using, board is placed on support frame and sliding table, and board and sliding table are pushed to slide forward along body synchronously in straight line, and saw blade is rotated to cut board.

[0004] The sliding table saw has the following deficiencies:

[0005] I. The stop ruler and the plate support frame are fixedly installed, the stop ruler cannot freely translate or slide to the front end or the rear end along the plate support frame. The plate cannot be freely selected to be placed horizontally at the front end of the stop ruler or the rear end of the stop ruler according to the size of the plate. Specifically, when the plate is long, the plate should be placed horizontally on the plate support frame at the rear end of the stop ruler, so that there is enough space to place the plate. And make the plate and the stop ruler horizontally close, and the plate and the stop ruler are perpendicular to the saw blade, then press and push the plate and the stop ruler straight forward with hands, finally make the saw blade cut off one side of the plate to cut into a straight edge; when the plate is wide, the plate should be placed horizontally on the plate support frame at the front end of the stop ruler, then push the stop ruler and the plate straight forward with hands, which is more convenient and saves labor. And because the stop ruler abuts against the rear end of the plate, the plate will not rotate or shift under the action of the saw blade when the saw blade cuts the plate.

Each quick locking device 6 can correspond to the position of the fixed shaft 200 and is used to lock the two fixed shafts 200 at the two ends of the stop ruler 2. Each quick locking device 6 includes a positioning seat 600, a guide positioning groove 601 is formed at the front end of each positioning seat 600, which is used to guide the fixed shaft 200 to enter and limit the lateral movement of the fixed shaft 200. A locking assembly 602 is installed on each positioning seat 600, which can enter the limiting groove 201 of the fixed shaft 200 to limit the longitudinal movement of the fixed shaft 200.

[0058] Referring again to Figure 1 When sawing the long edge of the long material 10 vertically, the material 10 occupies a large space because it is very long. If the material 10 is placed horizontally on the material placing rack 1 at the front end of the stop ruler 2, the material placing rack 1 and the sliding table 8 do not have enough space to support and enough travel to move the material 10 to the direction of the saw blade 9 to complete the processing. Therefore, the material 10 needs to be placed horizontally on the material placing rack 1 at the rear end of the stop ruler 2. A stop piece 202 is also installed on the stop ruler 2, which is arranged at a right angle of 90 degrees with the stop ruler 2. The stop piece 202 can move left and right along the length direction of the stop ruler 2 and be fixed. It can be used to push the end of the material 10 away from the saw blade 9 to prevent the material 10 from moving. Specifically, the stop ruler 2 can be pushed or pulled to make the stop ruler 2 and the translation plate 302 move synchronously through the translation sliding block 301 along the translation guide rail at the front end of the material placing rack 1, and finally make the stop ruler 2 move to the front end of the material placing rack 1. At this time, the two fixed shafts 200 at the two ends of the stop ruler 2 will automatically enter the two guide positioning grooves 601 of the two positioning seats 600 at the front ends of the material placing rack 1. The two guide positioning grooves 601 are used to guide the fixed shaft 200 to enter and limit the lateral movement of the fixed shaft 200. The two locking assemblies 602 on the two positioning seats 600 correspond to enter the limiting grooves 201 of the two fixed shafts 200 to limit the longitudinal movement of the two fixed shafts 200. At this time, the two ends of the stop ruler 2 are fixed, and then the material 10 is placed horizontally on the material placing rack 1 at the rear end of the stop ruler 2, so that the material 10 is parallel and close to the stop ruler 2, and the material 10 is at a right angle with the saw blade 9. Then, the material 10 is held and pushed by hand to make the material placing rack 1 and the sliding table 8 move linearly to the direction of the saw blade 9, and finally complete the sawing work of the long edge of the material 10.

[0059] Referring again to Figure 2When vertically sawing the short side of a long material 10, if the material 10 is placed flat on the rear end of the material rack 1, and the material 10 is pressed and pushed by hand, because the material 10 is very long, the force applied by the hand on the material 10 is uneven, and the hand cannot firmly press the material 10. When one end of the material 10 is cut by the saw blade 9, the other end will tilt and shift. Therefore, it is necessary to translate the ruler 2 to the rear end of the material rack 1. The method of translating the ruler 2 and locking the ruler 2 is the same as the method described above. Then place the material 10 flat on the material rack 1 at the front end of the ruler 2, and then hold and push the ruler 2 by hand. The ruler 2 will push the material 10 stably and evenly, and then the material rack 1 and the sliding table 8 will move straight toward the direction of the saw blade 9, and finally complete the sawing of the long side of the material 10. The above method can prevent the material 10 from tilting and shifting during sawing, and the processing accuracy is high and labor-saving.

[0060] Refer again Figure 3 、 Figure 4 When sawing the material 10 in a non-vertical manner, for example, to make the angle between the material 10 and the saw blade 9 acute or obtuse, it is necessary to rotate the ruler 2 to achieve this. Specifically, when the ruler 2 is fixed to the front or rear end of the material unloading rack 1, completely loosen the locking assembly 602 at the end away from the sliding table 8, and the other locking assembly 602 can be completely loosened or partially loosened, as long as the fixed shaft 200 at that end can rotate freely; then, push the ruler 2 at the end away from the sliding table 8, and the ruler 2 and the swing angle plate 400 can rotate along the connecting shaft 401 to achieve the swing angle; when the ruler 2 and the swing angle plate 400 rotate synchronously, the ruler 2 can also move left or right through the left and right sliding device 5 to adapt to its rotation. In addition, one end of the ruler 2 can also move forward or backward through the front and rear translation device 3. After that, it moves; when the ruler 2 swings to the predetermined position so that the angle between the ruler 2 and the saw blade 9 meets the angle required for sawing wood, the locking assembly 602 close to one end of the sliding table 8 is locked to the fixed shaft 200 at the same end; because the fixed shaft 200 at the other end of the ruler 2 has been away from the locking assembly 602 at that end during the rotation of the ruler 2, and cannot be fixed by the locking assembly 602 at that end, it is necessary to tighten the locking piece 405 to make it rest against the bottom of the material rack 1 to prevent the connecting shaft 401 from rotating. At this time, the ruler 2 is restricted by the above two fixed points and cannot move forward or backward or rotate to ensure the accuracy of sawing.

[0061] The blocking ruler 2 of the application can be translated forward and backward on the material placing rack 1 to the front end or the rear end of the material placing rack 1, and the material 10 can be placed on the front end or the rear end of the blocking ruler 2 according to the length and shape of the processed material 10, which is convenient to move and has good applicability, and the material 10 is not easy to move during processing, so that the processing precision is high. The blocking ruler 2 can be rotated to change the included angle between the blocking ruler 2 and the saw blade 9, so that not only straight edges but also bevels can be sawed on the material 10, which can meet various processing requirements. The quick locking device 6 and the locking part 405 can conveniently and quickly fasten the blocking ruler 2, and the blocking ruler 2 can be conveniently fixed whether it is located at the front end, the rear end or one end of the material placing rack 1 after rotation between the front end and the rear end of the material placing rack 1, which is simple to operate, convenient to lock and loosen, and can improve work efficiency.

[0062] In some embodiments, the guide positioning groove 601 is opened towards one end where the fixed shaft 200 is located, so that the fixed shaft 200 can smoothly enter the guide positioning groove 601. The width of the opening of the guide positioning groove 601 is greater than the diameter of the fixed shaft 200, and the width of the lower end of the guide positioning groove 601 is less than the diameter of the fixed shaft 200. The wide opening facilitates the entry of the fixed shaft 200, and the narrow lower end allows the fixed shaft 200 to closely adhere to the outer wall of the fixed shaft 200, preventing the fixed shaft 200 from shaking. The positioning seat 600 on one side of the guide positioning groove 601 is provided with a slot 603, the locking assembly 602 includes a rotating rod 602A and a tightening rod 602B, the first end of the rotating rod 602A is hinged in the slot 603 and can freely rotate; the tightening rod 602B is threadedly connected in the screw hole on the side wall of the first end of the rotating rod 602A, and the tightening rod 602B penetrates vertically from the rotating rod 602A, the second end of the rotating rod 602A can enter the limiting groove 201 of the fixed shaft 200 after rotation and closely adhere to each other, and the tightening rod 602B can abut against the side wall plane of the positioning seat 600 after tightening to prevent the rotating rod 602A from rotating. Through the rotating rod 602A and the tightening rod 602B, the two fixed shafts 200 can be fixed in the two corresponding guide positioning grooves 601, which is very convenient to lock and loosen the fixed shaft 200, and can improve stability, processing precision and work efficiency.

[0063] In some embodiments, two adjusting through holes 604 are provided side by side at the top of the rear end of the positioning seat 600, which are waist-shaped holes or long holes, and the positioning seat connectors are screwed into the screw holes on the material rack 1 after passing through the adjusting through holes 604, so as to fix the positioning seat 600 and the material rack 1 together, and the positioning seat connectors can be bolts or other suitable components; a top pressing block 11 is installed on the material rack 1 at the rear end of the positioning seat 600, two top pressing rods 110 are threadedly connected side by side on the side wall at the rear end of the top pressing block 11, which can be bolts or other suitable components, the top pressing rods 110 penetrate the top pressing block 11 and can push the positioning seat 600 to move, for adjusting the levelness of the positioning seat 600.
