Description

Technical Field

[0001] This application relates to the technical field of positioning devices, and in particular to an auxiliary positioning mechanism for a wood cutting machine. Background Technology

[0002] A wood cutter is a tool specifically designed for cutting wood, boards, or other wood products.

[0003] Chinese utility model patent CN211491951U discloses a wood cutting machine, including a worktable. A cylindrical groove is formed on the upper surface of the worktable, and a cylindrical, open-topped rotating cylinder is placed within the groove. A cover plate is provided on the rotating cylinder, and a through hole is formed on the cover plate. A cutting wheel is placed within the through hole, and a drive motor for rotating the cutting wheel is located inside the rotating cylinder. In use, the drive motor drives the cutting wheel to rotate. Wood is placed on the top of the worktable, the cutting part is aligned with the cutting wheel, and then the wood slides past the cutting wheel, at which point the cutting wheel cuts the wood.

[0004] However, it was found that the wood needed to be measured and marked with a ruler or other tools before it could be cut, which was quite troublesome. Summary of the Invention

[0005] To facilitate wood cutting, this application provides an auxiliary positioning mechanism for a wood cutting machine.

[0006] This application provides an auxiliary positioning mechanism for a wood cutting machine, which adopts the following technical solution:

[0007] An auxiliary positioning mechanism for a wood cutting machine, comprising:

[0008] The placement seat slides on the worktable, and the sliding direction of the placement seat is the same as the cutting direction of the wood.

[0009] A positioning post is provided on the top of the placement base;

[0010] The positioning block slides on the positioning post, and the sliding direction of the positioning block is perpendicular to the sliding direction of the placement seat;

[0011] A fixing element is provided on the positioning block, and when the positioning block stops sliding, it is fixed to the positioning post by the fixing element;

[0012] A positioning plate is hinged to the positioning block. The positioning plate can be flipped up and down. When cutting, the wood abuts against the positioning plate and the vertical side wall of the positioning post.

[0013] By adopting the above technical solution, the position of the placement seat is far away from the saw wheel before cutting. At this time, the positioning block is slid to adjust the position of the positioning plate. After the adjustment is completed, the positioning block is fixed by the fixing component. Then, the positioning plate is flipped to abut the top of the positioning block, and the wood is abutted against the positioning plate and the positioning post. Then the placement seat is slid to cut the wood. The same steps can be followed when cutting other wood.

[0014] Optionally, the fixing component is a fixing bolt, which is threadedly connected to the positioning block. When the positioning block is fixed, the fixing bolt abuts against the placement seat.

[0016] Optionally, the positioning plate is provided with a mounting base, and the mounting base is provided with a clamping assembly, the clamping assembly including a clamping wheel, a clamping column, a clamping bolt, and an elastic clamping element;

[0017] The clamping bolt is threaded to the positioning plate, and the top of the positioning block has a positioning groove for the clamping bolt to be inserted.

[0018] The clamping post slides up and down on the mounting base, the clamping wheel is rotatably connected to the clamping post, the elastic clamping member is disposed on the clamping post, the elastic clamping member drives the clamping wheel to abut against the wood, and when the wood slides toward the positioning plate, the clamping wheel is rolled and connected to the top of the wood;

[0019] The mounting base has a straightening column hinged to its side wall, and the mounting base is provided with a torsion spring that drives the straightening column to flip upward and away from the mounting base.

[0020] The straightening column is rotatably connected to a straightening wheel on the side away from the mounting base. The mounting base is provided with a transmission component. When the pressing column slides away from the placement base, the transmission component drives the straightening column to flip so that the straightening wheel presses against the wood.

[0021] By adopting the above technical solution, the clamping wheel and the straightening wheel abut against the wood, so that the wood is kept in contact with the placement seat and the positioning column, which helps to improve the flatness of the wood cutting end face.

[0022] Optionally, the transmission component is a drive rope, which slides through the mounting base, with one end connected to the abutment post and the other end connected to the straightening post;

[0023] When the clamping column moves upward away from the placement seat, the drive rope pulls the straightening column downward and flips it over.

[0024] By adopting the above technical solution, when the clamping column moves upward, the drive rope pulls the straightening column downward and flips it over, which helps the straightening wheel push the wood to abut the positioning column.

[0025] Optionally, the elastic clamping element is a clamping spring, a limiting block is provided on the side wall of the clamping column, the clamping spring is sleeved on the clamping column, one end of the clamping spring abuts against the limiting block, and the other end abuts against the bottom of the mounting base.

[0026] By adopting the above technical solution, the elastic release of the clamping mechanism allows the clamping wheel to push the wood against the placement seat.

[0027] Optionally, a power shaft is rotatably connected inside the abutment post, and a coil spring is wound around the outer periphery of the power shaft. One end of the coil spring is engaged with the power shaft, and the other end is engaged with the abutment post.

[0028] The abutment post is equipped with a drive assembly. When the wooden board slides toward the positioning plate and drives the abutment wheel to rotate, the drive assembly drives the power shaft to rotate, and the rotation direction of the power shaft is opposite to that of the abutment wheel.

[0029] A control component is provided on the clamping post. When the wooden board abuts against the positioning plate, the control component controls the power shaft to work in conjunction with the clamping wheel. At this time, the clamping wheel pushes the wood toward the positioning plate.

[0030] By adopting the above technical solution, the spring is released, allowing the clamping wheel to push the wood against the positioning plate, which helps to further improve the flatness of the wood cutting end face.

[0031] Optionally, the drive assembly includes a drive helical gear, a connecting helical gear, and a transmission helical gear;

[0032] The transmission helical gear is rotatably connected to the clamping column, the clamping wheel is coaxially provided with a rotating shaft, the driving helical gear is provided on the outer periphery of the rotating shaft, and the transmission helical gear meshes with the driving helical gear;

[0033] The connecting helical gear is disposed on the outer periphery of the power shaft, and the transmission helical gear meshes with the connecting helical gear.

[0034] By adopting the above technical solution, the driving helical gear drives the connecting helical gear to rotate through the transmission helical gear, so that the power shaft and the rotating shaft can rotate in opposite directions.

[0035] Optionally, the control assembly includes a control rope, a control column, a push column, a control spring, a control block, and a drive spring;

[0036] The driving helical gear is rotatably connected to the rotating shaft, the control block slides on the rotating shaft along the direction perpendicular to the central axis, and the control spring pushes the control block against the inner wall of the driving helical gear;

[0037] The control column is slidably connected to the rotating shaft, and the end face of the power shaft is formed with a plug-in groove corresponding to the rotating shaft. The drive spring is disposed on the rotating shaft. When the rotating shaft is aligned with the plug-in groove, the drive spring pushes the control column to insert into the plug-in groove. At this time, the power shaft and the rotating shaft are linked together.

[0038] The control rope is slidably threaded through the rotating shaft, with one end of the control rope connected to the control column and the other end connected to the control block;

[0039] When the control column is inserted into the insertion slot, the control rope pulls the control block away from the drive helical gear;

[0040] The push column is slidably connected to the power shaft and can protrude into the insertion groove. The abutting column has a receiving groove for accommodating the sliding of the push column when the power shaft rotates. The abutting column has an inlet and outlet surface for the push column to enter and exit the receiving groove.

[0041] When the power shaft and the rotating shaft rotate in opposite directions, the push column slides in the receiving groove. When the push column slides away from the receiving groove through the inlet / outlet surface, the push column pushes the control column to disengage from the insertion groove.

[0042] By adopting the above technical solution, when the coil spring is released, the clamping wheel can push the wood towards the positioning plate.

[0043] Optionally, the abutment post is provided with a push block, the push block is inclined to form a push surface, and when the wood slides on the push surface, the abutment post slides upward.

[0044] By adopting the above technical solution, when the wood moves toward the positioning plate, it slides on the pushing surface, which facilitates the upward movement of the pressing column.

[0046] 1. By using positioning plates to limit the movement of timber, there is no need to measure and mark all the timber, greatly reducing the tediousness of cutting timber;

[0047] 2. The clamping wheel and the straightening wheel abut against the wood, keeping the wood in contact with the placement seat and the positioning post, which helps to improve the flatness of the wood cutting end. Attached Figure Description

[0059] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0060] This application discloses an auxiliary positioning mechanism for a wood cutting machine.

[0061] Example 1

[0062] See Figure 1 and Figure 2 The auxiliary positioning mechanism includes a placement seat 1, which is a cuboid structure. The placement seat 1 slides on the top of the worktable, and a saw wheel for cutting wood is rotatably connected to the worktable. The worktable is equipped with a motor to drive the saw wheel to rotate. The sliding direction of the placement seat 1 is parallel to the cutting direction of the saw wheel. During cutting, the wood is placed on the placement seat 1 and protrudes outwards from the placement seat 1 towards the saw wheel. Then, the placement seat 1 is slid, and as the wood passes the saw wheel, the saw wheel cuts the wood.

[0063] The auxiliary positioning mechanism also includes a positioning post 2, a positioning block 3, and a positioning plate 4. The positioning post 2 is a cuboid structure and is fixed to the top of the placement base 1. The length direction of the positioning post 2 is parallel to the length direction of the placement base 1. The top of the positioning post 2 has an inverted "T"-shaped groove 21 extending along its length direction. The positioning block 3 slides in the groove 21. The end face of the positioning block 3 is an inverted "T"-shaped structure, and the top of the positioning block 3 protrudes out of the groove 21. The sliding direction of the positioning block 3 is perpendicular to the sliding direction of the placement base 1.

[0064] The positioning block 3 is equipped with a fixing component, namely a fixing bolt 31, which is threadedly connected to the positioning block 3. Before sliding the positioning block 3, the fixing bolt 31 is reversed. At this time, the bottom of the fixing bolt 31 moves away from the bottom wall of the slide groove 21, and the positioning block 3 enters a free rotation state. When the positioning block 3 stops sliding, the fixing bolt 31 is rotated clockwise until the bottom of the fixing bolt 31 abuts against the bottom wall of the slide groove 21. At this time, the fixing bolt 31 is pressed against the bottom wall of the slide groove 21, so that the positioning block 3 enters a fixed state.

[0065] The positioning plate 4 includes a plate body 41 and a column body 42. The column body 42 is fixed in the middle of the side wall of the plate body 41, and the side of the column body 42 away from the plate body 41 is hinged to the top of the positioning block 3. The column body 42 can be flipped up and down. When the column body 42 is flipped to abut the top of the positioning block 3, the end face of the plate body 41 facing the saw wheel has a rectangular structure and the plate body 41 is parallel to the saw wheel.

[0066] The top of the placement seat 1 has a placement area 11 for placing wood. Before cutting, the placement seat 1 is away from the saw wheel. Then, the column 42 is flipped so that its bottom abuts against the top of the positioning block 3 and the plate 41 is in the placement area 11. At this time, the vertical distance from the plate 41 to the cutting surface of the saw wheel is the length of the wood after cutting. Therefore, the length of the wood after cutting can be ensured by adjusting the position of the positioning block 3, without having to measure and mark the wood before each cutting.

[0067] After flipping the column 42 so that its bottom abuts against the top of the positioning block 3 and the plate 41 is in the placement area 11, slide the wood sidewall against the vertical sidewall along the length of the column towards the plate 41 until the end of the wood abuts against the plate 41; finally, slide the placement seat 1, and when it passes the saw wheel, the saw wheel cuts off the part of the wood that protrudes from the placement seat 1. Then, the placement seat 1 can be driven away from the saw wheel and the cut wood can be removed. The same operating steps described above can be used to cut the wood.

[0068] The implementation principle of the auxiliary positioning mechanism of a wood cutting machine according to Embodiment 1 of this application is as follows:

[0069] Before cutting, adjust the position of the fixing block. When cutting, flip the column 42 until the bottom of the column 42 abuts against the top of the positioning block 3 and the plate 41 is in the placement area 11. Then, the wood abuts against the plate 41 and the vertical side wall of the positioning column 2 at the same time. Finally, slide the placement seat 1 through the saw wheel to complete the cutting of the wood. The same steps are followed when cutting other wood.

[0070] Example 2

[0071] See Figure 3 During the cutting process, it was found that if the wood shifts during the cutting process and is not kept in close contact with the mounting base 1 or positioning post 2, the flatness of the wood end face will be affected.

[0072] See Figure 3 and Figure 4 Therefore, the difference between Embodiment 2 and Embodiment 1 is that the positioning plate 4 is fixedly connected to the side facing the saw wheel with a mounting base 5. The mounting base 5 is provided with a clamping component, a straightening column 51 and a straightening wheel 53, which are used to keep the wood in contact with the board body 41 and the positioning column 2.

[0073] See Figure 4 and Figure 5 The clamping assembly includes a clamping wheel 62, a clamping column 61, a clamping bolt 6, and an elastic clamping element; the clamping bolt 6 is threadedly connected to the column 42, and a positioning groove 32 is formed on the top of the positioning block 3. When the column 42 is clamped against the top of the positioning block 3, the clamping bolt 6 is aligned with the positioning groove 32. At this time, the clamping bolt 6 is inserted into the positioning groove 32, and the clamping bolt 6 restricts the column 42 from rotating.

[0074] See Figure 4 and Figure 6The clamping post 61 has a "T"-shaped structure and slides up and down on the mounting base 5. The clamping post 61 protrudes downwards from the mounting base 5 to the outside. A stop block is fixedly connected to the side wall of the clamping post 61, and a groove is formed inside the mounting base 5 to allow the stop block to slide up and down, thus preventing the clamping post 61 from sliding downwards out of the mounting base 5. A rotating shaft 621 is rotatably connected to the bottom of the clamping post 61, and a clamping wheel 62 is fixedly connected to the rotating shaft 621. The rotating shaft 621 and the clamping wheel 62 are coaxially arranged. When the wood slides towards the board 41, the clamping wheel 62 rolls against the top of the wood.

[0075] See Figure 3 and Figure 4 The elastic clamping element is a clamping spring 612. A limiting block 611 is fixedly connected to the vertical side wall of the clamping post 61, and the limiting block 611 is located outside the mounting base 5. The clamping spring 612 is sleeved on the outer periphery of the clamping post 61, with one end of the clamping spring 612 abutting against the top of the limiting block 611 and the other end abutting against the bottom of the mounting base 5. When the clamping spring 612 is released elastically, it pushes the clamping post 61 downward. A "7"-shaped pushing block 9 is fixedly connected to the side wall of the clamping post 61. The bottom of the pushing block 9 is inclined to form a pushing surface 91, which faces the direction of the saw wheel.

[0076] When the wood slides towards the board 41, it slides on the pushing surface 91. At this time, the pushing block 9 drives the pressing column 61 to slide upward, so that the pressing wheel 62 can roll on the top of the wood. At the same time, the pressing spring 612 enters the compression state, applying a downward force to the pressing column 61, so that the pressing wheel 62 pushes the wood to fit against the placement seat 1.

[0077] A straightening shaft is rotatably connected to the side wall of the mounting base 5. A straightening column 51 is fixedly connected to the outer periphery of the straightening shaft. A straightening wheel 53 is rotatably connected to the side of the straightening column 51 away from the mounting base 5. A torsion spring 52 is sleeved on the outer periphery of the straightening shaft. One end of the torsion spring 52 abuts against the straightening column 51, and the other end abuts against the mounting base 5. When the torsion spring 52 is released elastically, it pushes the straightening column 51 to flip upward.

[0078] Mounting base 5 is equipped with a transmission component, which is a drive rope 54. The drive rope 54 is elastic. The drive rope 54 slides through the mounting base 5, is wound around the straightening shaft, and one end of the drive rope 54 is fixed to the outer periphery of the straightening shaft. The other end of the drive rope 54 is fixed to the outer periphery of the straightening column 51.

[0079] In the initial state, the clamping wheel 62 is away from the mounting base 5, and the straightening column 51 is perpendicular to the clamping column 61. When the clamping column 61 slides upward, it pulls the drive rope 54, which in turn pulls the straightening shaft to rotate, causing the straightening column 51 to flip downward until the straightening wheel 53 abuts against the side wall of the wood and pushes the wood to fit against the positioning column 2. As the wood slides towards the board 41, the straightening wheel 53 rolls against the side wall of the wood.

[0080] See Figure 6 A power groove 615 is formed inside the clamping post 61, and a power shaft 613 is rotatably mounted in the power groove 615. The power shaft 613 and the rotating shaft 621 are coaxially arranged and adjacent to each other. A coil spring 614 is provided inside the clamping post 61, and a coil spring groove 616 communicating with the power groove 615 is formed inside the clamping post 61. The coil spring 614 is sleeved on the outer periphery of the power shaft 613 and located in the coil spring groove 616. One end of the coil spring 614 is snapped and fixed to the outer periphery of the power shaft 613, and the other end is snapped and fixed to the groove wall of the coil spring groove 616.

[0081] See Figure 5 and Figure 6 The clamping post 61 is equipped with a drive component. When the wooden board slides toward the positioning plate 4 and drives the clamping wheel 62 to rotate, the drive component drives the power shaft 613 to rotate. At this time, the rotation direction of the power shaft 613 is opposite to the rotation direction of the rotating shaft 621.

[0082] See Figure 7 and Figure 8 The drive assembly includes a drive helical gear 7, a connecting helical gear 71, and a transmission helical gear 72.

[0083] The transmission helical gear 72 is rotatably connected to the clamping post 61, and the driving helical gear 7 rotates within the clamping post 61 and is located on the outer periphery of the rotating shaft 621. The transmission helical gear 72 and the driving helical gear 7 mesh with each other. The connecting helical gear 71 is rotatably connected within the clamping post 61 and fixed on the outer periphery of the power shaft 613. The transmission helical gear 72 and the connecting helical gear 71 mesh with each other. When the wood approaches the board 41 and the clamping wheel 62 rotates, the rotating shaft 621 drives the driving helical gear 7 to rotate. At this time, the transmission helical gear 72 drives the connecting helical gear 71 to rotate, causing the power shaft 613 to drive the coil spring 614 into an elastic winding state.

[0084] See Figure 7 and Figure 9 The clamping post 61 is equipped with a control component, which includes a control rope 85, a control post 81, a push post 82, a control spring 83, a control block 84, and a drive spring 8.

[0085] The drive helical gear 7 is rotatably connected to the rotating shaft 621. Multiple control grooves extending towards the central axis are formed on the outer periphery of the rotating shaft 621. Control blocks 84 correspond to each control groove and are located within them. Control blocks 84 can slide within the control grooves along the direction perpendicular to the central axis. The shape of the control blocks 84 is adapted to the shape of the inner periphery of the drive helical gear 7, and a rubber layer is fixed to each control block 84 to abut against the drive helical gear 7. Control springs 83 correspond to each control groove and are installed within them. One end of the control spring 83 abuts against the side of the control block 84 away from the drive helical gear 7, and the other end abuts against the groove wall away from the groove opening. When the control spring 83 is released elastically, it pushes the control block 84 to abut against the inner periphery of the drive helical gear 7, at which point the rotating shaft 621 and the drive helical gear 7 are in a linked state.

[0086] A sliding groove extending along the central axis is formed at the end of the rotating shaft 621 near the power shaft 613. There is a gap between the sliding groove and the central axis of the rotating shaft 621. The control post 81 slides within the sliding groove. A drive spring 8 is installed within the sliding groove, with one end abutting against the end face of the control post 81 and the other end abutting against the side wall of the sliding groove away from the opening. A corresponding insertion groove 6131 is formed on the end face of the power shaft 613 facing the rotating shaft 621. When the rotating shaft 621 and the power shaft 613 rotate simultaneously in opposite directions, the control post 81 and the insertion groove 6131 move closer together. When the control post 81 and the insertion groove 6131 are aligned, the drive spring 8 drives the control post 81 to insert into the insertion groove 6131, at which point the power shaft 613 and the rotating shaft 621 enter a linked state.

[0087] The control rope 85 slides through the rotating shaft 621. One end of the control rope 85 passes through the drive spring 8 and is fixedly connected to the control post 81. The other end of the control rope 85 is fixedly connected to multiple connecting ropes 851, each corresponding to a control block 84. The connecting rope 851 passes through the control spring 83 and is fixed to the control block 84. When the control post 81 is inserted into the insertion slot 6131, the control rope 85 pulls the control block 84 away from the drive helical gear 7 through the connecting ropes 851. At this time, the drive helical gear 7 and the rotating shaft 621 enter a state of relative rotation.

[0088] A push hole is formed inside the drive shaft 613, extending axially and communicating with the insertion groove 6131. ​​The push post 82 is slidably connected to the push hole. When the control post 81 is inserted into the insertion groove 6131, the push post 82 slides out of the insertion groove 6131 and protrudes out of the drive shaft 613.

[0089] See Figure 8 and Figure 10The side wall of the power groove 615 away from the rotation shaft 621 has a receiving groove 617 extending along an arc-shaped trajectory, and the portion of the push column 82 protruding from the power shaft 613 can slide in the receiving groove 617. The side wall of the power groove 615 away from the rotation shaft 621 has an inclined inlet / outlet surface 618, and the push column 82 enters and exits the receiving groove 617 by sliding on the inlet / outlet surface 618.

[0090] See Figure 8 and Figure 9 In the initial state, the clamping wheel 62 is stationary. At this time, the control column 81 is away from the insertion groove 6131, the pushing column 82 protrudes into the insertion groove 6131, and the end of the pushing column 82 away from the insertion groove 6131 slides on the wall of the power groove 615.

[0091] When the clamping wheel 62 rotates, the power shaft 613 and the rotating shaft 621 rotate in opposite directions. At this time, the control column 81 approaches the insertion slot 6131, while the pushing column 82 slides towards the receiving slot 617 (the receiving slot 617 is in...). Figure 10 (Winning bid). When the wood abuts against the board 41, the control post 81 aligns with the insertion slot 6131, the push post 82 aligns with the receiving slot 617, and the control spring 83 pushes the control post 81 into the insertion slot 6131, pushing the push post 82 out of the push hole, so that the push post 82 enters the receiving slot 617; at this time, the drive helical gear 7 and the rotating shaft 621 enter a relative rotation state, while the power shaft 613 and the rotating shaft 621 enter a coaxial rotation state. Then the coil spring 614 is released elastically, driving the power shaft 613 to rotate, and at the same time the rotating shaft 621 follows the power shaft 613 to rotate in the same direction, so that the pressing wheel 62 pushes the wood against the board 41 (the board 41 is in Figure 3 (Winning bid). When the coil spring 614 drives the power shaft 613 to rotate, the push column 82 slides in the receiving groove 617 and is close to the inlet / outlet surface 618. When the wood moves away from the clamping wheel 62 or the clamping wheel 62 can rotate freely, the power shaft 613 drives the push column 82 to slide in the inlet / outlet surface 618. At this time, the push column 82 slides out of the receiving groove 617 and pushes the control column 81 out of the insertion groove 6131. ​​At this time, the power shaft 613 and the rotating shaft 621 enter a state of separation, while the rotating shaft 621 enters a state of linkage with the drive helical gear 7 through the clamping block. When the coil spring 614 continues to drive the power shaft 613 to rotate, the push column 82 moves away from the inlet / outlet surface 618, and the rotating shaft 621 and the power shaft 613 rotate in opposite directions, so that the control column 81 moves away from the insertion groove 6131.

[0092] The implementation principle of the auxiliary positioning mechanism of a wood cutting machine according to Embodiment 2 of this application is as follows:

[0093] When the wood slides towards the board 41, it pushes the clamping post 61 upward, causing the clamping wheel 62 to roll on the top of the wood and the straightening wheel 53 to roll on the side wall of the wood, which helps to keep the wood in close contact with the placement seat 1 and the positioning post 2. At the same time, the coil spring 614 is released, causing the clamping wheel 62 to push the wood to keep it in contact with the board 41. At this time, when the wood is cut, the flatness of the cut end face is greatly improved.

[0094] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
