Description

Technical Field

[0001] This application relates to the technical field of wood saws, and particularly to a wood cutting table. Background Art

[0002] A circular saw is a commonly used tool for cutting various materials, especially wood. The circular saw uses a saw blade driven by an electric motor to cut wood horizontally and longitudinally to form multiple wood segments or wooden boards.

[0003] For the horizontal, i.e., radial, cutting of wood, it is relatively easy, and a general handheld electric saw can meet the requirements. However, when performing longitudinal, i.e., lengthwise, cutting, since the length of wood is generally relatively large, a cutting table is used. The saw blade and the motor are installed at the bottom of the cutting table, and the saw blade extends out from the saw hole on the tabletop. The operator places the wood on the tabletop and pushes it forward, and the saw blade can cut the wood longitudinally. Since there are generally requirements for the thickness of the wooden board during the cutting process, a structure for adjusting the thickness of the wooden board is usually provided, such as CN217992786U and CN207027732U.

[0004] However, during the cutting process, the diameters of the wood are not all large enough. Sometimes, for some woods with smaller diameters, it is necessary to cut them in half from the middle, that is, cut the wood into two parts with the same thickness. For the requirement of bisecting small-diameter wood and cutting large-diameter wood with a fixed thickness, the current cutting table cannot meet both at the same time. Utility Model Content

[0005] The embodiments of this application provide a wood cutting table to solve the problem that the existing cutting table cannot meet both the requirement of bisecting small-diameter wood and cutting large-diameter wood with a fixed thickness at the same time.

[0006] The embodiments of this application provide a wood cutting table, which includes a tabletop, a saw blade, a first baffle and a second baffle. The saw blade is arranged at the bottom of the tabletop, and a part of the saw blade passes through the tabletop and exposes above the tabletop. Both the first baffle and the second baffle are slidably arranged on the tabletop, and the first baffle and the second baffle are respectively located on both sides of the saw blade. A distance adjustment component is arranged at the bottom of the tabletop. The distance adjustment component includes a first contact plate, a second contact plate and an adjustment wheel. The adjustment wheel is rotatably arranged at the bottom of the tabletop. The first contact plate and the second contact plate are respectively arranged at the bottoms of the first baffle and the second baffle, and both the first contact plate and the second contact plate are located below the tabletop. The first contact plate is vertically movably arranged at the bottom of the first baffle. The adjustment wheel is respectively in contact with the top surface of the first contact plate and the bottom surface of the second contact plate. Under the action of the adjustment wheel, the first contact plate and the second contact plate rotate simultaneously to keep the first baffle and the second baffle at an equal distance from the saw blade. When the first contact plate moves downward, it disengages from the adjustment wheel, so that the first baffle and the second baffle can move independently.

[0007] In a possible implementation, slide holes are provided on the tabletop, distributed on both sides of the saw blade. A first connecting rod is provided at the bottom of the first baffle. The first connecting rod passes through the slide hole on one side of the saw blade on the tabletop and extends below the tabletop. The first contact plate is vertically movably arranged on the first connecting rod. A second connecting rod is provided at the bottom of the second baffle. The second connecting rod passes through the slide hole on the other side of the saw blade on the tabletop and extends below the tabletop. The second contact plate is arranged on the second connecting rod.

[0008] In a possible implementation, an activity groove is provided on the side surface of the first connecting rod. The first contact plate is inserted into the activity groove and vertically moves in the activity groove.

[0009] In a possible implementation, an adjusting bolt is screwed on the first baffle. The adjusting bolt extends into the activity groove and is rotatably connected to the first contact plate. When the adjusting bolt rotates, the vertical height of the first contact plate is adjusted, so that the first contact plate contacts or disengages from the adjusting wheel.

[0010] In a possible implementation, springs are connected to both the first connecting rod and the second connecting rod. The ends of the springs are connected to the bottom of the tabletop. The springs provide an elastic force for the first baffle and the second baffle to move towards each other.

[0011] In a possible implementation, both the first contact plate and the second contact plate are racks, and the adjusting wheel is a gear. The adjusting wheel meshes with the first contact plate and the second contact plate respectively.

[0012] In a possible implementation, a positioning bolt is screwed on the second baffle. The positioning bolt passes through the second baffle and contacts the tabletop. After the positioning bolt is tightened, it abuts against the tabletop to fix the second baffle at a fixed position on the tabletop.

[0013] In a possible implementation, scales are also provided on the tabletop. The extending direction of the scales is parallel to the moving direction of the second baffle, and the ends of the scales are directly opposite to the edge of the saw blade.

[0014] A wood cutting table in the present application has the following advantages:

[0015] The distance between the two baffles is adjusted by the distance adjusting component. Moving the first contact plate downward can make the two baffles move separately, so that wood with a larger diameter can be cut into wooden boards with a fixed thickness. After moving the first contact plate upward, the two baffles can move towards or away from each other simultaneously to ensure that the saw blade is on the midline of the two baffles, and wood with a smaller diameter can be bisected, achieving the effect that the same cutting table can meet different cutting requirements.

Detailed implementation manners

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0021] Figure 1-2Schematic diagram of a wood cutting table structure provided by an embodiment of the present application. An embodiment of the present application provides a wood cutting table, including a tabletop 100, a saw blade 200, a first baffle 310 and a second baffle 320. The saw blade 200 is arranged at the bottom of the tabletop 100, and a part of the saw blade 200 passes through the tabletop 100 and exposes from above the tabletop 100. Both the first baffle 310 and the second baffle 320 are slidably arranged on the tabletop 100, and the first baffle 310 and the second baffle 320 are respectively located on both sides of the saw blade 200. It is characterized in that a distance adjusting assembly is arranged at the bottom of the tabletop 100. The distance adjusting assembly includes a first contact plate 313, a second contact plate 323 and an adjusting wheel 102. The adjusting wheel 102 is rotatably arranged at the bottom of the tabletop 100. The first contact plate 313 and the second contact plate 323 are respectively arranged at the bottoms of the first baffle 310 and the second baffle 320, and both the first contact plate 313 and the second contact plate 323 are located below the tabletop 100. The first contact plate 313 is vertically movably arranged at the bottom of the first baffle 310. The adjusting wheel 102 is respectively in contact with the top surface of the first contact plate 313 and the bottom surface of the second contact plate 323. Under the action of the adjusting wheel 102, the first contact plate 313 and the second contact plate 323 rotate simultaneously, so that the first baffle 310 and the second baffle 320 maintain the same distance from the saw blade 200. When the first contact plate 313 moves downward, it disengages from the adjusting wheel 102, so that the first baffle 310 and the second baffle 320 can move independently.

[0022] Exemplarily, the overall structure of the cutting table is similar to that of a table. There are multiple support legs below the tabletop 100. Through these support legs, the tabletop 100 can be at an appropriate height, which is convenient for the operator to place the wood on the tabletop 100 and perform cutting operations.

[0023] A motor is arranged at the bottom of the tabletop 100. The rotating shaft of the motor is connected to the saw blade 200. When the operator turns on the power of the motor through a switch arranged at the bottom of the tabletop 100, the saw blade 200 will rotate driven by the motor, and then cut the wood placed on the tabletop 100. It should be understood that a cutting hole needs to be arranged on the tabletop 100. The width of the cutting hole is slightly larger than the thickness of the saw blade 200, and the length of the cutting hole is slightly larger than the length of the part of the saw blade 200 exposed above the tabletop 100. Therefore, the saw blade 200 can expose from the cutting hole and rotate normally.

[0024] Both the first baffle 310 and the second baffle 320 are in a long strip shape and are parallel to each other and both are parallel to the saw blade 200. When the wood to be cut is placed between the two baffles, the operator can easily push the wood along the channel between the baffles, and then the saw blade 200 cuts the wood. By setting the saw blade 200 and the two baffles to be parallel, it can be ensured that when the saw blade 200 cuts the wood, it can cut along the length direction of the wood, or in other words, the axial direction.

[0025] In an embodiment of the present application, sliding holes are provided on the table top 100, and the sliding holes are distributed on both sides of the saw blade 200. A first connecting rod 312 is provided at the bottom of the first baffle plate 310, and the first connecting rod 312 extends to the bottom of the table top 100 after passing through the sliding hole on the table top 100 located on one side of the saw blade 200, and a first contact plate 313 is vertically movably provided on the first connecting rod 312, and a second connecting rod 322 is provided at the bottom of the second baffle plate 320, and the second connecting rod 322 extends to the bottom of the table top 100 after passing through the sliding hole on the table top 100 located on the other side of the saw blade 200, and a second contact plate 323 is provided on the second connecting rod 322.

[0026] Two sliding holes are provided below the first baffle 310 and the second baffle 320. Therefore, two first connecting rods 312 are provided at the bottom of the first baffle 310, and two second connecting rods 322 are also provided at the bottom of the second baffle 320. After the two first connecting rods 312 are respectively inserted into the two sliding holes, the first baffle 310 can slide on the table 100 along the length direction of the sliding holes, that is, in a direction perpendicular to the saw blade 200. Correspondingly, after the two second connecting rods 322 are respectively inserted into the two sliding holes, the second baffle 320 can slide on the table 100 along the length direction of the sliding holes.

[0027] Furthermore, a movable groove 314 is provided on the side of the first connecting rod 312, and the first contact plate 313 is inserted into the movable groove 314 and moves vertically in the movable groove 314. The width of the movable groove 314 is equivalent to the width of the first contact plate 313, but the height of the movable groove 314 is greater than the thickness of the first contact plate 313. When the first contact plate 313 moves to the bottom of the movable groove 314, the first contact plate 313 will completely break away from the contact with the adjusting wheel 102. At this time, the first baffle 310 and the second baffle 320 will be able to move separately and will no longer move synchronously toward or away from each other. In this case, the first baffle 310 or the second baffle 320 can be fixed on the table 100. After ensuring that the distance between the first baffle 310 or the second baffle 320 and the saw blade 200 is the required wood thickness, the wood can be pushed along the first baffle 310 or the second baffle 320, and then the wood can be cut into a board of required thickness by the saw blade 200. When the first contact plate 313 moves to the top of the movable groove 314, the first contact plate 313 will contact the adjusting wheel 102. At this time, since the adjusting wheel 102 is in contact with the top surface of the first contact plate 313 and the bottom surface of the second contact plate 323 respectively, when one of the first contact plate 313 and the second contact plate 323 moves, the other will also move synchronously in the opposite direction, thereby ensuring that the first baffle plate 310 and the second baffle plate 320 can move the same distance at the same time and always keep the same distance from the saw blade 200.

[0028] Further, the adjusting wheel 102 can be a smooth wheel, while the first contact plate 313 and the second contact plate 323 can be smooth plates. The adjusting wheel 102, the first contact plate 313, and the second contact plate 323 are driven by friction. In other embodiments, both the first contact plate 313 and the second contact plate 323 are racks, and the adjusting wheel 102 is a gear. The adjusting wheel 102 meshes with the first contact plate 313 and the second contact plate 323 respectively. In this meshing manner, it can ensure that the transmission of movement and rotation is more stable and there will be no slipping. Whether it is a smooth wheel or a gear, the adjusting wheel 102 is connected to the bottom surface of the table 100 through a hanging rod 101.

[0029] Further, a slope can be provided at the ends on the same side of the first baffle 310 and the second baffle 320, and the slope faces the direction of wood insertion. Since the diameters of the woods to be cut are not exactly the same, when cutting a wood with a larger diameter, the wood can be inserted into the slopes at the ends of the two baffles. Under the action of the slopes, the baffles are gradually expanded, and finally the wood is closely attached to the sides of the baffles.

[0030] In a possible embodiment, an adjusting bolt 311 is screwed on the first baffle 310. The adjusting bolt 311 extends into the moving slot 314 and is rotatably connected to the first contact plate 313. When the adjusting bolt 311 rotates, the vertical height of the first contact plate 313 is adjusted, so that the first contact plate 313 contacts or disengages from the adjusting wheel 102.

[0031] Exemplarily, the position where the adjusting bolt 311 is located is directly above the sliding hole. Therefore, when the adjusting bolt 311 passes through the first baffle 310, it can extend into the first connecting rod 312 and finally expose from the moving slot 314. A connecting slot matching the diameter of the adjusting bolt 311 is provided on the top surface at the end of the first contact plate 313. The side surface at the end of the adjusting bolt 311 is a smooth surface. After the smooth surface part is rotationally inserted into the connecting slot, when the adjusting bolt 311 rotates, it can move up and down in the vertical direction on the first baffle 310, thereby driving the first contact plate 313 to move up and down in the moving slot 314, realizing the switching between the contact and disengagement of the first contact plate 313 and the adjusting wheel 102.

[0032] In a possible embodiment, springs are connected to both the first connecting rod 312 and the second connecting rod 322. The ends of the springs are connected to the bottom of the table 100. The springs provide an elastic force for the first baffle 310 and the second baffle 320 to move towards each other.

[0033] Exemplarily, after the springs are provided, the first baffle 310 and the second baffle 320 can apply sufficient clamping force to the wood, so that the wood moves along a fixed channel on the table 100 without skewing or other situations.

[0034] In a possible embodiment, a positioning bolt 321 is screwed onto the second baffle 320. The positioning bolt 321 passes through the second baffle 320 and contacts the tabletop 100. After the positioning bolt 321 is tightened, it abuts against the tabletop 100, so that the second baffle 320 is in a fixed position on the tabletop 100.

[0035] Exemplarily, since the tightened positioning bolt 321 needs to contact the tabletop 100, the positioning bolt 321 needs to be arranged at a position outside the sliding hole. After the spring is arranged, although the spring will always apply a pulling force to the second baffle 320, after the positioning bolt 321 is tightened, the frictional force between the positioning bolt 321 and the tabletop 100 will exceed the pulling force of the spring, so that the second baffle 320 is in the position positioned by the positioning bolt 321 and will not be pulled by the spring to the position closest to the saw blade 200.

[0036] In a possible embodiment, a scale is further arranged on the tabletop 100. The extending direction of the scale is parallel to the moving direction of the second baffle 320, and the end of the scale is directly opposite to the edge of the saw blade 200.

[0037] Exemplarily, corresponding length values can also be marked near the scale. This length value represents the distance between the saw blade 200 and the second baffle 320, that is, the thickness of the template after the wood is cut. Therefore, when adjusting the positioning bolt 321, the positioning bolt 321 can be loosened first, and then the second baffle 320 can be moved to the required position with reference to the scale and then the positioning bolt 321 can be tightened.

[0038] Although the preferred embodiments of the present application have been described, those skilled in the art can make additional changes and modifications to these embodiments once they learn the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0039] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application is also intended to include these modifications and variations.
