Description

Technical Field

[0001] This invention relates to the field of sliding table saw technology, and specifically to a sliding table saw. Background Technology

[0002] A sliding table saw is a type of machinery used for woodworking, primarily for straight cutting, but it can also achieve beveling or other types of cuts with appropriate attachments. The core feature of a sliding table saw is its sliding worktable, also called a push table. This push table is perpendicular to the saw blade, and the user can push the wood on the worktable closer to the saw blade; the saw blade then rotates to complete the cutting action. A sliding table saw typically includes the following main components:

[0003] The sliding table is used to support and push the wood towards the saw blade; the worktable, also called the feed rack, provides a flat surface for placing the wood; the stop has graduations to set the cutting width, ensuring accuracy and keeping materials such as boards, timber, or logs parallel and in close contact with the stop, maintaining a fixed angle between the material and the saw blade to prevent displacement; the saw blade is the rotating blade that performs the actual cutting work. Sliding table saws are widely used in furniture manufacturing, woodworking, and other industries due to their high precision, efficiency, and safety. Compared to traditional handheld circular saws, sliding table saws can cut wood more accurately while reducing the risk of direct operator contact with the saw blade, thus improving safety.

[0004] Utility model patent application CN 220593469 U discloses a sliding table saw. It includes a machine body and a sliding table mounted on the machine body, the sliding table being capable of reciprocating linearly along the machine body. A support frame is mounted on one side of the sliding table, and a saw blade is mounted on the machine body on the other side of the sliding table. The saw blade is driven to rotate by a saw blade motor mounted on the machine body. In use, a sheet of material is placed on the support frame and the sliding table, and the sheet of material and the sliding table are pushed forward synchronously along the machine body. The rotating saw blade cuts the sheet of material.

[0005] This sliding table saw has the following shortcomings: 1. The stop and the plate support frame are fixedly installed. The stop cannot freely move or slide along the plate support frame to the front or rear end. It also cannot freely choose whether to place the plate flat at the front or rear end of the stop according to the plate's dimensions. Specifically, when the plate is long, it should be placed flat on the plate support frame at the rear end of the stop to provide sufficient space. The plate should be horizontally and tightly against the stop, with both the plate and the stop perpendicular to the saw blade. Then, press and push the plate and stop forward in a straight line until the saw blade cuts one side of the plate into a straight edge. When the plate is wide, it should be placed flat on the plate support frame at the front end of the stop, and then pushed forward in a straight line. This is more convenient and less strenuous, and because the stop holds the rear end of the plate, the plate will not rotate or shift under the action of the saw blade during cutting. 2. The stop cannot freely swing or rotate axially along the plate support frame. Therefore, the angle between the stop and the board and the saw blade cannot be freely adjusted; it can only maintain a 90-degree right angle between the stop and the board and the saw blade. It can only cut a straight edge on one side of the board, but not a beveled edge. Therefore, it cannot cut boards into various geometric shapes such as triangles and rhombuses using the saw blade, resulting in poor applicability. Summary of the Invention

[0006] In order to overcome at least one of the technical problems existing in the prior art, the present invention provides a sliding table saw with a stop that can move forward and backward, slide left and right and rotate, and can also quickly lock the stop.

Each quick-locking device includes a positioning seat, and a guide positioning groove is opened at the front end of each positioning seat to guide the fixed shaft into and restrict the lateral movement of the fixed shaft. A locking component is installed on each positioning seat, which can enter into the limit groove of the fixed shaft to restrict the longitudinal movement of the fixed shaft.

[0008] In some embodiments, the guide positioning groove is opened towards the end where the fixed shaft is located. The width of the opening of the guide positioning groove is greater than the diameter of the fixed shaft, and the width of the lower end of the guide positioning groove is less than the diameter of the fixed shaft. A slot is provided on the positioning seat on one side of the guide positioning groove. The locking assembly includes a rotating rod and a tightening rod. The first end of the rotating rod is hinged in the slot, and the tightening rod is threaded to the side wall of the first end of the rotating rod. The second end of the rotating rod can enter the limiting groove of the fixed shaft after rotation. The tightening rod can abut against the side wall of the positioning seat after tightening to prevent the rotating rod from rotating.

[0009] In some embodiments, two adjustment through holes are provided side by side at the top of the rear end of the positioning seat. The positioning seat connector passes through the adjustment through holes to fix the positioning seat to the feeding rack. A top pressure block is installed on the feeding rack at the rear end of the positioning seat. Two top pressure rods are threaded to the side wall at the rear end of the top pressure block. The top pressure rods can pass through the top pressure block and push the positioning seat to move, thereby adjusting the level of the positioning seat.

[0010] In some embodiments, the guide positioning groove is V-shaped, the slot is U-shaped, the limiting groove is an annular groove, which is opened along the outer wall of the fixed shaft, and the rotating rod is provided with an outwardly convex arc surface that matches the limiting groove.

[0011] In some embodiments, a fine-tuning device is also included, comprising a rack mounted on one side of one of the translation guides, a gear meshing with the rack, the gear being sleeved and fixed on a fine-tuning shaft, and the fine-tuning shaft being rotatably connected to the translation plate.

[0012] In some embodiments, a fine-tuning handwheel is installed at the lower end of the fine-tuning shaft, and bearing seats are installed on the upper and lower surfaces of the translation plate respectively. The upper end of the fine-tuning shaft extends out of the translation plate, and the fine-tuning shaft is rotatably connected to the bearings in the two bearing seats in sequence.

[0013] In some embodiments, the feeding rack includes an outer frame and multiple reinforcing beams installed inside the outer frame; two translation guide rails are installed parallel to each other on the top of the two reinforcing beams located in the middle of the outer frame; the lower end of the connecting shaft passes through the gap between the two reinforcing beams; a rotating handwheel is threaded to the end of the connecting shaft; and the locking element is a plate with a length greater than the width of the gap.

[0014] In some embodiments, the feeding rack is horizontally arranged, with one end of the feeding rack vertically connected to the sliding table of the push table saw. Support plates are symmetrically installed on the top of the left and right ends of the feeding rack, and feeding rollers are installed side by side on the outer side of the support plate at the end away from the sliding table.

[0015] Beneficial effects: (i) The stop can move horizontally back and forth on the feeding rack to the front or rear end of the feeding rack. Depending on the length and shape of the processed board, the board can be placed flat at the front or rear end of the stop. It is easy to move, has good applicability, and the board is not easy to shift during processing, resulting in high processing accuracy. (ii) The stop can rotate to change the angle between itself and the saw blade. Therefore, it can not only cut straight edges on the board, but also cut beveled edges, which can meet a variety of processing needs. (iii) The quick-lock device and locking parts can easily and quickly fasten the stop. Whether the stop is located at the front or rear end of the feeding rack, or one end is located in the area between the front and rear ends of the feeding rack after rotation, it can be easily fixed. The operation is simple, and locking and unlocking are convenient, which can improve work efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] In the prior art, the sliding table saw includes a machine body 7 and a sliding table 8 mounted on the machine body 7. The sliding table 8 can move back and forth in a straight line along the machine body 7. A feeding rack 1 is installed on one side of the sliding table 8, and a rotating saw blade 9 is installed on the machine body 7 on the other side of the sliding table 8. Materials 10 such as boards and timber are placed flat on the feeding rack 1. When the feeding rack 1 and the sliding table 8 move toward the end where the saw blade 9 is located, the high-speed rotating saw blade 9 will cut off one end of the material 10 that it passes through.

[0045] Reference Figures 1-15This sliding table saw includes a horizontally arranged feeding rack 1, a stop 2 horizontally mounted on the feeding rack 1, and also includes a front-to-back translation device 3, a tilting device 4, a left-to-right sliding device 5, and a quick-locking device 6. The front-to-back translation device 3 includes two parallel translation guide rails 300 fixed on the feeding rack 1, a translation slider 301 slidably mounted on the two translation guide rails 301, and a translation plate 302 fixedly mounted on the translation slider 301. The translation plate 302 can reciprocate linearly along the translation guide rails 300 via the translation slider 301, thereby moving the stop 2 to any position between the front end, rear end, or both ends of the feeding rack 1. The tilting device 4 includes a tilting plate 4. 00. A connecting shaft 401 is vertically fixed to the lower end of the swing plate 400; a bearing 402 is fixed in the bearing mounting through hole of the translation plate 302; and a connecting sleeve 403 is fixed to the bottom of the translation plate 302. One side wall of the swing plate 400 can be set as an arc surface 404, which can be used with devices such as a rotary magnetic encoder and annular magnetic grid to detect the rotation angle value. The connecting shaft 401 is rotatably connected to the translation plate 302 through the bearing 402. The lower end of the connecting shaft 401 passes through the bearing 402 and the connecting sleeve 403 axially. The connecting shaft 401 and the connecting sleeve 403 are rotatably connected. When the translation plate 302 does not slide or slides, the swing plate 400 can... The axial rotation causes the stop 2 to rotate, changing the angle between the stop 2 and the saw blade 9. A thread is provided on the lower outer wall of the connecting shaft 401, and a locking element 405 is threadedly connected to the lower end of the connecting shaft 401. The locking element 405 is located at the bottom of the feeding rack 1. When tightened, the locking element 405 abuts against the bottom of the feeding rack 1, preventing the connecting shaft 401 from rotating. After the stop 2 rotates to the desired angle via the swing plate 400, to prevent the stop 2 and the swing plate 400 from rotating, the locking element 405 can be tightened, causing it to move towards the bottom of the feeding rack 1, ultimately making the locking element 405 and the bottom surface of the feeding rack 1 in close contact. The locking function is as follows: The left and right sliding device 5 includes a sliding slider 500 fixed on the top of the swing plate 400 and a sliding guide rail 501 slidably mounted on the sliding slider 500. The bottom of the stop 2 can be fixedly connected to the sliding guide rail 501 by screws. When the stop 2 and the swing plate 400 rotate synchronously, the stop 2 and the sliding guide rail 501 can also slide left and right along the sliding slider 500 mounted on the top of the swing plate 400. Fixed shafts 200 are symmetrically installed at both ends of the bottom of the stop 2. Both fixed shafts 200 are installed perpendicular to the stop 2 and are on the same straight line. A limiting groove 201 is opened at the lower end of the fixed shaft 200.There are four quick-locking devices 6, arranged in pairs. Two are located at the front ends of the feeding rack 1, and the other two are located at the rear ends of the feeding rack 1. Each quick-locking device 6 corresponds to the position of the fixed shaft 200 and is used to lock the two fixed shafts 200 located at the bottom ends of the stop 2. Each quick-locking device 6 includes a positioning seat 600. A guide positioning groove 601 is provided at the front end of each positioning seat 600 to guide the fixed shaft 200 into the rack and restrict its lateral movement. A locking component 602 is installed on each positioning seat 600, which can enter the limiting groove 201 of the fixed shaft 200 to restrict its longitudinal movement.

[0046] Refer to Figure 1 When vertically sawing the long side of a long material 10, because the material 10 is very long, it will occupy a lot of space. If the material 10 is placed flat on the feeding rack 1 at the front end of the stop 2, the feeding rack 1 and the sliding table 8 do not have enough space to support it, nor enough stroke for the material 10 to move towards the saw blade 9 to complete the processing. Therefore, the material 10 needs to be placed flat on the feeding rack 1 at the rear end of the stop 2. A baffle 202 is also installed on the stop 2. The baffle 202 is set at a 90-degree right angle to the stop 2. The baffle 202 can move left and right and be fixed along the length of the stop 2. It can be used to hold the end of the material 10 away from the saw blade 9 to prevent the material 10 from shifting. Specifically, the stop ruler 2 can be pushed or pulled, causing the stop ruler 2 and the translation plate 302 to move synchronously along the front end of the translation guide rail feeding rack 1 via the translation slider 301. Ultimately, the stop ruler 2 moves to the front end of the feeding rack 1. At this point, the two fixed shafts 200 located at both ends of the bottom of the stop ruler 2 will automatically enter the two guide positioning grooves 601 of the two positioning seats 600 located at both ends of the front end of the feeding rack 1. The two guide positioning grooves 601 are used to guide the fixed shafts 200 into the rack and restrict their lateral movement. The two locking components 602 on 600 are inserted into the limiting grooves 201 of the two fixed shafts 200 to restrict the longitudinal movement of the two fixed shafts 200. At this time, both ends of the stop 2 are fixed, and then the material 10 is placed flat on the feeding rack 1 at the rear end of the stop 2, so that the material 10 is parallel and close to the stop 2, and the material 10 is perpendicular to the saw blade 9. Then, the material 10 is held and pushed by hand, so that the feeding rack 1 and the sliding table 8 move in a straight line towards the saw blade 9, and finally the long side sawing of the material 10 is completed.

[0047] Refer to Figure 2When sawing the short side of a long piece of material 10 perpendicularly, if the material 10 is placed flat at the rear end of the feeding rack 1 and pressed and pushed by hand, the force applied to the material 10 is uneven due to its length, making it impossible to hold the material 10 firmly. As the saw blade 9 cuts, one end of the material 10 will tilt and shift. Therefore, it is necessary to move the stop 2 to the rear end of the feeding rack 1. The method for moving and locking the stop 2 is the same as described above. Then, the material 10 is placed flat on the feeding rack 1 located at the front end of the stop 2. The stop 2 is then held and pushed by hand, and it will steadily push the material 10 with even force. The feeding rack 1 and the sliding table 8 then move linearly towards the saw blade 9, finally completing the sawing of the long side of the material 10. This method prevents the material 10 from tilting and shifting during sawing, resulting in high processing accuracy and less effort.

[0048] Refer to Figure 3 , Figure 4 When sawing material 10 non-perpendicularly, for example, when the angle between material 10 and saw blade 9 is to be acute or obtuse, the stop ruler 2 needs to be rotated. Specifically, when the stop ruler 2 is fixed at the front or rear end of the feeding rack 1, the locking component 602 at the end away from the sliding table 8 is completely released, and the other locking component 602 can be completely or partially released, as long as the fixed shaft 200 at that end can rotate freely; then, by pushing the stop ruler 2 at the end away from the sliding table 8, the stop ruler 2 and the swing plate 400 can rotate along the connecting shaft 401 to achieve the swing angle; when the stop ruler 2 and the swing plate 400 rotate synchronously, the stop 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 stop ruler 2 can also move forward or backward through the front and rear translation device 3. The stopper 2 moves backward; when the stopper 2 swings to the predetermined position, so that the angle between the stopper 2 and the saw blade 9 meets the angle required for sawing the wood, the locking component 602 near 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 stopper 2 has moved away from the locking component 602 at that end during the rotation of the stopper 2, it cannot be fixed by the locking component 602 at that end. Therefore, it is necessary to tighten the locking part 405 so that it abuts against the bottom of the feeding rack 1 to prevent the connecting shaft 401 from rotating. At this time, the stopper 2 is restricted by the above two fixed points and cannot move forward or backward or rotate to ensure the accuracy of sawing.

[0049] The stop ruler 2 of this application can be moved back and forth on the feeding rack 1 to the front or rear end of the feeding rack 1. Depending on the length and shape of the material 10 being processed, the material 10 can be freely placed at either the front or rear end of the stop ruler 2. This design allows for easy movement, good applicability, and prevents the material 10 from shifting during processing, resulting in high processing accuracy. The stop ruler 2 can rotate to change the angle between itself and the saw blade 9. Therefore, it can not only cut straight edges on the material 10 but also beveled edges, meeting various processing needs. The quick-lock device 6 and locking element 405 can conveniently and quickly secure the stop ruler 2. Whether the stop ruler 2 is located at the front or rear end of the feeding rack 1, or one end is located in the area between the front and rear ends of the feeding rack 1 after rotation, it can be easily fixed. The operation is simple, locking and unlocking are convenient, and work efficiency is improved.

[0050] In some embodiments, the guide positioning groove 601 is opened towards the 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 large width at the opening facilitates the entry of the fixed shaft 200, and the small width at the lower end allows it to fit tightly against the outer wall of the fixed shaft 200, preventing the fixed shaft 200 from shaking. A slot 603 is provided on the positioning seat 600 on one side of the guide positioning groove 601. The locking assembly 602 includes a rotating rod 602A and a tightening rod 602B. The first end of the rotating rod 602A is hinged. Within the slot 603, it can rotate freely; the tightening rod 602B is threaded into the threaded hole on the side wall of the first end of the rotating rod 602A. The tightening rod 602B passes vertically out of 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 the two are in close contact. After tightening, the tightening rod 602B can abut against the side wall plane of the positioning seat 600 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. Locking and loosening the fixed shafts 200 is very convenient, which can improve stability, processing accuracy and work efficiency.

[0051] 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. These holes are oblong or elongated. The positioning seat connector passes through the adjusting through holes 604 and is screwed into the screw hole on the feeding rack 1 to fix the positioning seat 600 and the feeding rack 1 together. The positioning seat connector can be a suitable component such as a bolt. A top pressure block 11 is installed on the feeding rack 1 at the rear end of the positioning seat 600. Two top pressure rods 110 are threaded to the side wall at the rear end of the top pressure block 11. These rods can be suitable components such as bolts. The top pressure rods 110 pass through the top pressure block 11 and can push the positioning seat 600 to move, thereby adjusting the level of the positioning seat 600. In use, first loosen the two positioning seat connectors so that the positioning seat 600 can move relative to the two positioning seat connectors. Then, use a right-angle ruler or other protractor as a reference, and then turn any one of the top pressure rods 110. The top pressure block 11 pushes the positioning seat 600 to move slowly for fine adjustment. Finally, the positioning seat 600 and the stop ruler 2 form a 90-degree right angle with the saw blade 9, thereby ensuring that the edge of the material 10 cut by the saw blade 9 is a straight edge.

[0052] In some embodiments, the guide positioning groove 601 is V-shaped to facilitate the entry of the fixed shaft 200 and reduce the difficulty of docking; the slot 603 is U-shaped to facilitate the rotation of the rotating rod 602A and avoid obstruction; the limiting groove 201 is an annular groove to facilitate the installation of the fixed shaft 200, and it is opened along the outer wall of the fixed shaft 200. The rotating rod 602A is provided with an outwardly convex arc surface 602C that matches the limiting groove 201, which increases the contact area between the two, improves stability, prevents or reduces the lateral or axial movement of the fixed shaft 200, thereby improving the processing accuracy of the material 10.

[0053] In some embodiments, a fine-tuning device 12 is also included, which includes a rack 120 mounted on one side of one of the translation guide rails 300, a gear 121 meshing with the rack 120, the gear 121 being sleeved and fixed on a fine-tuning shaft 122, and the fine-tuning shaft 122 being rotatably connected to the translation plate 302; when the fine-tuning shaft 122 is rotated, the fine-tuning shaft 122 drives the gear 121 to rotate synchronously and move linearly along the rack 120. Through the cooperation of the fine-tuning device 12 with measuring tools such as a ruler, the position of the stop 2 can be controlled more precisely to improve the processing accuracy of the material 10.

[0054] In some embodiments, a fine-tuning handwheel 123 is installed at the lower end of the fine-tuning shaft 122, which can increase the contact surface with the hand and make it more convenient and effortless; bearing seats 124 are installed on the upper and lower surfaces of the translation plate 302 respectively, making it more flexible and effortless to rotate the fine-tuning shaft 122; the upper end of the fine-tuning shaft 122 extends out from the translation plate 302, and the fine-tuning shaft 122 is rotatably connected to the bearings in the two bearing seats 124 in sequence.

[0055] In some embodiments, the feeding rack 1 includes an outer frame 100 and multiple reinforcing beams 101 installed inside the outer frame 100 to improve stability; two translation guide rails 300 are installed in parallel on the top of the two reinforcing beams 101 located in the middle of the outer frame 100; the lower end of the connecting shaft 401 passes through the gap 102 between the two reinforcing beams 101; a rotating handwheel is threaded to the end of the connecting shaft 401, which can increase the contact surface with the hand and make it more convenient and labor-saving; the locking member 405 is a rectangular plate with a length greater than the width of the gap 102, so that the upper outer surface of the locking member 405 can be in close contact with the bottom surface of the two reinforcing beams 101 to prevent slippage.

[0056] In some embodiments, the feeding rack 1 is horizontally arranged, and one end of the feeding rack 1 is vertically connected to the sliding table 8 of the push table saw, which can improve accuracy. Support plates 103 are symmetrically installed on the top of the left and right ends of the feeding rack 1. Feeding rollers 104 are installed side by side on the outer side of the support plate 103 away from the sliding table 8. The rollers and support plates 103 are at the same height from the ground, so that the material 10 is kept horizontal while being perpendicular to the saw blade 9. The feeding rollers 104 can reduce the difficulty of feeding, and when the feeding rollers 104 rotate, they can reduce the friction with the surface of the material 10, saving effort and reducing damage to the surface of the material 10.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
