Description

Technical Field

[0001] This utility model relates to the field of sawing machines, specifically a sawing machine with a protective structure. Background Technology

[0002] Sawing machines are widely used in industrial production for cutting various materials. However, the high-speed rotation of the saw blade and its sharp edge bring significant safety risks. If the operation is improper or an accident occurs, the operator is easily injured due to direct contact with the saw blade. The flying debris and noise generated during the sawing process may also threaten the operator's health.

[0003] During the cutting process, saw blades easily generate a large amount of debris. This debris can not only injure operators, but also affect cutting accuracy and workpiece quality. In practical applications, saws not only need to have basic cutting functions, but also need to be able to adjust the tilt angle of the saw blade according to different cutting requirements. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a saw with a protective structure.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A saw with a protective structure includes a cutting table, with legs fixedly connected to the four corners of the bottom of the cutting table. A mounting opening is formed in the center of the top of the cutting table. Side panels are fixedly connected to the left and right sides of the top of the cutting table. A protective cover is fixedly connected between the tops of the two side panels, positioned above the mounting opening. An electric push rod is located below the mounting opening. The top of the output shaft of the electric push rod is fixedly connected to a base plate. Support rods are fixedly connected to the four corners of the top of the base plate. A mounting plate is fixedly connected between the tops of the four support rods. The outer wall of the mounting plate slides against the inner wall of the mounting opening. A cutting opening is formed in the center of the top of the mounting plate. A frame plate, which is box-shaped and opens vertically, is located inside the cutting opening. The frame extends forward and backward. A motor is fixedly installed in the middle of the left side wall of the frame. The output shaft of the motor passes through the middle of the left and right side walls of the frame and is rotatably connected to the left and right side walls of the frame. The frame has a saw blade inside, which is fixedly sleeved on the outer wall of the motor's output shaft. The bottom of the frame has a connecting frame, with both the front and rear ends of the connecting frame extending upward. The front and rear ends of the connecting frame are fixedly connected to the front and rear outer walls of the frame, respectively. Connecting shafts are fixedly connected to the top of the front and rear sides of the outer wall of the connecting frame. The opposite ends of the two connecting shafts are rotatably connected to the front and rear inner walls of the cutting opening. A handle is fixedly connected to the bottom of the connecting frame. The front and rear sides of the connecting frame have angle adjustment and limiting mechanisms.

[0007] The angle adjustment limiting mechanism includes an arc-shaped plate, the top of which is fixedly connected to the bottom of the mounting plate. The center of the arc-shaped plate is located on the axis of the connecting shaft. A sliding hole is opened in the middle of the front side wall of the arc-shaped plate, and a scale groove is opened at the top of the arc-shaped plate. The scale groove is located at the top of the sliding hole and is evenly distributed along the sliding hole. A slider is provided inside the sliding hole, and the slider slides in fit with the sliding hole. One end of the slider is fixedly connected to the outer wall of the connecting frame, and the other end of the slider is fixedly connected to the connecting plate. The bottom end of the connecting plate extends to the bottom of the arc-shaped plate, and a locking bolt is threaded to the bottom of the connecting plate. The top of the locking bolt abuts against the bottom of the arc-shaped plate. A pointer is fixedly connected to the outer wall of the connecting plate, and the pointer points to the scale groove.

[0008] The beneficial effects of this utility model are:

[0009] This invention allows for convenient adjustment of the saw blade height via an electric push rod, meeting the cutting needs of plates of different thicknesses.

[0010] The saw blade tilt angle adjustment is simple and quick. The operator only needs to hold the handle and rotate the connecting frame to adjust the angle. Furthermore, through the cooperation of the locking bolt and the pointer and scale groove, the tilt angle of the saw blade can be accurately fixed and adjusted, thereby enabling beveling of the board and improving the versatility and applicability of the saw.

[0011] The protective cover is located above the installation port and works with the side baffle on the top of the cutting table to form a relatively enclosed space. This effectively intercepts the wood chips generated during the cutting process, preventing them from splashing into the surrounding environment. It provides good protection for operators and equipment, ensuring the safety and cleanliness of the cutting process. Attached Figure Description

[0017] like Figure 1-4 As shown: A saw with a protective structure includes a cutting table 1, with support legs 2 fixedly connected to the four corners of the bottom of the cutting table 1. A mounting opening 3 is opened in the center of the top of the cutting table 1. Side baffles 4 are fixedly connected to the left and right sides of the top of the cutting table 1. A protective cover 5 is fixedly connected between the tops of the two side baffles 4. The protective cover 5 is located above the mounting opening 3. An electric push rod 6 is located below the mounting opening 3. The top of the output shaft of the electric push rod 6 is fixedly connected to a base plate 7. Support rods 8 are fixedly connected to the four corners of the top of the base plate 7. A mounting plate 9 is fixedly connected between the tops of the four support rods 8. The outer wall of the mounting plate 9 slides against the inner wall of the mounting opening 3. A cutting opening 10 is opened in the center of the top of the mounting plate 9. A frame plate 11 is located inside the cutting opening 10. The frame plate 11 is box-shaped and open at the top and bottom. Extending forward and backward, a motor 13 is fixedly installed in the middle of the left side wall of the frame plate 11. The output shaft of the motor 13 passes through the middle of the left and right side walls of the frame plate 11 and is rotatably connected to the left and right side walls of the frame plate 11. The frame plate 11 has a saw blade 12 inside, which is fixedly sleeved on the outer wall of the output shaft of the motor 13. The bottom of the frame plate 11 has a connecting frame 14, and the front and rear ends of the connecting frame 14 extend upward. The front and rear ends of the connecting frame 14 are fixedly connected to the front and rear outer walls of the frame plate 11, respectively. The top of the front and rear sides of the outer wall of the connecting frame 14 are fixedly connected to connecting shafts 15. The opposite ends of the two connecting shafts 15 are rotatably connected to the front and rear inner walls of the cutting opening 10. The bottom of the connecting frame 14 is fixedly connected to a handle 23. The front and rear sides of the connecting frame 14 have angle adjustment and limiting mechanisms.

[0018] The angle adjustment limiting mechanism includes an arc plate 16, the top of which is fixedly connected to the bottom of the mounting plate 9. The center of the arc plate 16 is located on the axis of the connecting shaft 15. A sliding hole 17 is opened in the middle of the front side wall of the arc plate 16. A scale groove 18 is opened on the top of the arc plate 16. The scale groove 18 is located at the top of the sliding hole 17 and is evenly distributed along the sliding hole 17. A slider 19 is provided inside the sliding hole 17. The slider 19 slides in conjunction with the sliding hole 17. One end of the slider 19 is fixedly connected to the outer wall of the connecting frame 14. The other end of the slider 19 is fixedly connected to the connecting plate 20. The bottom end of the connecting plate 20 extends to the bottom of the arc plate 16. A locking bolt 22 is threadedly connected to the bottom of the connecting plate 20. The top of the locking bolt 22 abuts against the bottom of the arc plate 16. A pointer 21 is fixedly connected to the outer wall of the connecting plate 20. The pointer 21 points to the scale groove 18.

[0019] When the height of the saw blade 12 needs to be adjusted, the electric push rod 6 is activated. The output shaft of the electric push rod 6 will extend and retract, and the base plate 7 fixedly connected to the top of the output shaft will move up and down accordingly.

[0020] The support rods 8, which are fixedly connected to the four corners of the top of the base plate 7, drive the mounting plate 9 to move up and down. Since the outer wall of the mounting plate 9 slides and engages with the inner wall of the mounting opening 3, the stability of the mounting plate 9 in moving up and down is ensured.

[0021] The frame plate 11 and the saw blade 12 inside the cutting opening 10 at the top center of the mounting plate 9 also move up and down, thereby realizing the adjustment of the height of the saw blade 12.

[0022] To adjust the tilt angle of the saw blade 12, the operator holds the handle 23 fixedly connected to the bottom of the connecting frame 14 and rotates the connecting frame 14 around the connecting shaft 15.

[0023] The front and rear ends of the connecting frame 14 are fixedly connected to the front and rear outer walls of the frame plate 11, respectively. The frame plate 11 will rotate together with the connecting frame 14, thereby driving the saw blade 12 inside the frame plate 11 to rotate, so as to adjust the tilt angle of the saw blade 12.

[0024] During rotation, the connecting shaft 15, which is fixedly connected to the top of the front and rear sides of the outer wall of the connecting frame 14, rotates on the inner walls of the front and rear sides of the cutting opening 10 to ensure smooth rotation.

[0025] The front and rear sides of the outer wall of the connecting frame 14 are slidably engaged with the sliding hole 17 in the middle of the front side wall of the arc plate 16 via the slider 19. One end of the slider 19 is fixedly connected to the outer wall of the connecting frame 14, and the other end is fixedly connected to the connecting plate 20.

[0026] After the saw blade 12 is adjusted to the required tilt angle, the top of the locking bolt 22 connected to the bottom thread of the connecting plate 20 is rotated to abut the bottom of the arc plate 16, thereby fixing the connecting plate 20 and thus fixing the tilt angle of the connecting frame 14 and the saw blade 12.

[0027] Meanwhile, the pointer 21 fixedly connected to the outer wall of the connecting plate 20 points to the scale groove 18 opened on the top of the arc plate 16, and the operator can accurately understand the tilt angle of the saw blade 12 according to the scale indicated by the pointer 21.

[0028] Place the board to be cut on the cutting table 1, start the motor 13, and the output shaft of the motor 13 drives the saw blade 12 to rotate.

[0029] Push the board so that it comes into contact with the rotating saw blade 12 to perform the cutting operation.

[0030] During the cutting process, the side baffles 4 fixedly connected to the top left and right sides of the cutting table 1 and the protective cover 5 fixedly connected between the tops of the two side baffles 4 can effectively intercept the wood chips generated during the cutting process and prevent wood chips from flying.

[0031] This utility model only protects the mechanical parts; the functions implemented by the software control part are not within the scope of protection of this utility model.
