Description

Technical Field

[0001] This utility model relates to the field of cutting technology, specifically to a cutting saw. Background Technology

[0002] A cutting saw is a tool that cuts materials using a high-speed rotating or reciprocating saw blade. It is widely used in many fields such as construction, manufacturing, woodworking, and metal processing. In the woodworking field, in order to adapt to diverse production needs, it is often necessary to cut wood at different angles.

[0003] For example, patent document CN222987143U, entitled "An Angle Adjustment Structure for a Cutting Saw," includes a mounting frame, a rotating shaft, a connecting rod, and an electric saw. A placement plate is fixedly connected to the side wall of the rotating shaft. Both side walls of the mounting frame are equipped with limiting mechanisms to restrict the position of the placement plate. Each limiting mechanism includes multiple clamping screws disposed on the side wall of the mounting frame, and friction blocks are movably mounted on the clamping screws. Two arc-shaped plates are fixedly connected to the lower end of the placement plate, and a rotating disk is rotatably connected to the upper end of the placement plate. A second scale is provided on the placement plate, and a first scale is provided on the side wall of the mounting frame. A fixing mechanism for securing the wood is provided on the side wall of the rotating disk. The wood can rotate not only laterally but also longitudinally within the mounting frame. For larger pieces of wood, angle adjustment of the electric saw is unnecessary.

[0004] However, in the process described in the literature, although the angle of the electric saw does not need to be adjusted during use, when adjusting the angle of the wood, it is necessary to first loosen several clamping screws one by one, then rotate the wood to the target angle by using the placement plate, and finally tighten all the clamping screws to fix the two curved plates. This makes the operation of adjusting the wood angle cumbersome, wastes manpower, and reduces the cutting efficiency of the wood. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cutting saw that solves the technical problem mentioned in the background art: adjusting the angle of wood is cumbersome, wastes manpower, and reduces the cutting efficiency of wood.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cutting saw includes a support frame with a cutting assembly for cutting wood. A worktable is rotatably mounted on the support frame, and a clamping assembly for clamping the wood is mounted on the worktable. A mounting frame is fixedly mounted on one side of the support frame, and a worm gear is rotatably mounted on the mounting frame. A driven shaft and a driving shaft are rotatably mounted on one side of the support frame. A driving gear and a worm wheel are fixedly mounted on the driving shaft, and the worm wheel meshes with the worm gear. The driven shaft is coaxially and fixedly connected to the worktable, and a driven gear is fixedly mounted on the driven shaft, meshing with the driving gear.

[0008] Furthermore, the cutting assembly includes a support rod mounted on a support frame, a protective cover, and a telescopic component mounted on the support rod for driving the protective cover to move vertically. A motor is fixedly mounted on one side of the protective cover, and the output end of the motor extends into the protective cover and is fixedly mounted with a cutting blade.

[0009] Furthermore, the telescopic component is an electric push rod, which is fixedly mounted on the top of the support frame, and the output end of the electric push rod is fixedly connected to the protective cover.

[0010] Furthermore, the clamping assembly includes a threaded rod rotatably mounted on the worktable, a clamping plate threadedly connected to the threaded rod, and a guide rod slidably mounted on the worktable, with the guide rod fixedly connected to the clamping plate.

[0011] Furthermore, a scale is fixedly provided on one side of the mounting frame, and a pointer that cooperates with the scale is fixedly provided on the driven shaft.

[0012] Furthermore, the diameter of the driving gear is smaller than the diameter of the driven gear.

[0013] The beneficial effects of this utility model are as follows: By setting up a worm gear, worm wheel, drive shaft, driven shaft, drive gear, and driven gear, when adjusting the angle of the wood, rotating the worm gear drives the worm wheel to rotate, the worm wheel drives the drive shaft to rotate, the drive shaft drives the drive gear to rotate, the drive gear drives the driven gear to rotate, the driven gear drives the driven shaft to rotate, the driven shaft drives the worktable to rotate, and the worktable drives the wood to rotate. Thus, when the wood rotates to the appropriate cutting angle, the worm gear stops rotating. Because the worm gear and worm wheel have a self-locking function, the worktable will not rotate after it stops rotating. The operation steps are simple and save manpower, thereby improving the efficiency of adjusting the wood cutting angle and thus improving the efficiency of cutting wood. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-3 As shown, a wood cutting saw includes a support frame 1, which comprises two spaced-apart support plates, with support columns evenly welded to the bottom of each support plate. A cutting assembly for cutting wood is mounted on the top of the support frame 1. The cutting assembly includes a support rod 4 mounted on the top of one of the support plates of the support frame 1, a protective cover 42, and a telescopic component mounted on the support rod 4 for vertically moving the protective cover 42. The telescopic component is an electric push rod 41, which is fixedly mounted on the top of the support frame 1. The output end of the electric push rod 41 extends downward through the support rod 4 and is fixedly connected to the protective cover 42. A motor 43 is fixedly mounted on one side of the protective cover 42. The output end of the motor 43 is rotatably connected to the protective cover 42, and the output end of the motor 43 extends into the protective cover 42 and is fixedly mounted with a cutting blade 44. By providing the protective cover 42, wood chips can be prevented from flying during wood cutting.

[0020] A workbench 2 is rotatably mounted between two support plates of the support frame 1. A clearance groove 21 is provided in the middle of the workbench 2 to allow the cutting blade 44 to pass freely, preventing damage to the workbench 2 when cutting wood. Connecting shafts (not shown in the figure) are fixedly mounted on the middle of both sides of the workbench 2, and these shafts are rotatably fitted with the corresponding support plates. A clamping assembly for pressing the wood is symmetrically mounted on the top of the workbench 2. The clamping assembly includes a threaded rod 3 rotatably mounted on the workbench 2, a clamping plate 32 threadedly connected to the outer circumference of the threaded rod 3, and guide rods 33 symmetrically slidably mounted on the workbench 2. Symmetrically arranged through holes are vertically provided on the workbench 2, and the guide rods 33 are slidably fitted with the corresponding through holes. The top of the guide rod 33 is fixedly connected to the bottom of the clamping plate 32. The bottom of the threaded rod 3 is a smooth section, and the bottom of the threaded rod 3 rotatably passes through the workbench 2. A rotating plate 31 is fixedly mounted on the top of the threaded rod 3, facilitating rotation of the threaded rod 3 via the rotating plate 31.

[0021] A U-shaped mounting frame 5 is fixedly installed on one side of the support frame 1. A worm gear 6 is rotatably mounted on the top of the mounting frame 5. A handwheel 64 is fixedly mounted on the top of the worm gear 6, and the bottom end of the worm gear 6 extends into the interior of the mounting frame 5 and is rotatably connected to the mounting frame 5. A driven shaft 65 and a driving shaft 61 are rotatably mounted on one side of the support frame 1. A driving gear 63 and a worm wheel 62 are fixedly sleeved on the outer periphery of the driving shaft 61 at intervals. The worm wheel 62 meshes with the worm gear 6. The driven shaft 65 passes through the corresponding support plate and is coaxially fixedly connected to the connecting shaft on one side of the worktable 2. A driven gear 66 is fixedly sleeved on the outer periphery of the driven shaft 65, and the driven gear 66 meshes with the driving gear 63.

[0022] A dial 71 is fixedly mounted on the side of the mounting frame 5 away from the support frame 1. The driven shaft 65 is rotatably connected to the mounting frame 5 at one end away from the support frame 1, and a pointer 7 that cooperates with the dial 71 is fixedly mounted on the end of the driven shaft 65 that passes through the mounting frame 5. This facilitates observation of the rotation angle of the worktable 2.

[0023] In another embodiment, the diameter of the driving gear 63 is smaller than that of the driven gear 66, and correspondingly, the number of teeth of the driving gear 63 is also less than that of the driven gear 66. Thus, when the driving gear 63 drives the driven gear 66 to rotate, it is easier to slow down the rotation speed of the driven gear 66, thereby facilitating the control of the rotation angle of the workbench 2 and improving the accuracy of adjusting the wood cutting angle.

[0024] Working principle:

[0025] When in use, place the wood on the workbench 2, with both ends of the wood positioned below the pressure plate 32. Then rotate the rotating plate 31, which in turn rotates the threaded rod 3. The threaded rod 3 then moves the pressure plate 32 downward, pressing the wood down to prevent it from moving when being cut.

[0026] When the cutting angle of the wood needs to be adjusted, the worm gear 6 is rotated by handwheel 64. The worm gear 6 drives the worm wheel 62 to rotate, which in turn drives the drive shaft 61 to rotate. The drive shaft 61 drives the drive gear 63 to rotate, which in turn drives the driven gear 66 to rotate. The driven gear 66 drives the driven shaft 65 to rotate, which in turn drives the worktable 2 to rotate. The worktable 2 then drives the wood to rotate. By observing the scale position indicated by the pointer 7 on the dial 71, the handwheel 64 is stopped when the wood reaches the appropriate cutting angle. Because the worm gear 6 and worm wheel 62 have a self-locking function, the worktable 2 will not rotate after it stops, thus improving the efficiency of adjusting the wood cutting angle and consequently improving the efficiency of cutting the wood.

[0027] Finally, the electric push rod 41 is started and slowly moved down. The electric push rod 41 drives the protective cover 42 to move down, and at the same time the motor 43 is started. The motor 43 drives the cutting blade 44 to rotate, and the cutting blade 44 cuts the wood.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
