Description

Technical Field

[0001] This invention relates to an adjustable linear cutting machine, belonging to the field of cutting tool technology. Background Technology

[0002] A linear cutting machine is a tool that uses a motor to drive a saw blade to cut a workpiece. Existing linear cutting machines include a frame, a motor mounted on the frame via guide rails and a slider, and a saw blade mounted on the motor's output shaft. In use, the workpiece is placed on a support platform below the saw blade, the position of the workpiece is adjusted, the motor is started, and the motor moves to perform linear cutting on the workpiece. With this type of linear cutting machine, the saw blade can only move along the length of the guide rail, thus it can only perform linear cutting in one direction. After cutting one section, it can be cut again in the same direction at another location. Alternatively, if a change in cutting direction is needed, the workpiece must be moved horizontally or rotated before linear cutting can begin. For heavy workpieces, horizontal movement and rotation are relatively difficult, making linear cutting of the workpiece inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable linear cutting machine, which solves the technical defects of existing linear cutting machines where the saw blade can only move in one direction, and the plate needs to be moved if the cutting position needs to be changed, making it inconvenient to cut heavy workpieces.

[0004] To solve the above problems, the technical solution adopted by the present invention is: an adjustable linear cutting machine, including a frame, a horizontal slide plate, a vertical slide plate, a drive motor, a mounting base, connecting frames A, and a cutting motor. The frame is fixed to a fixed object in use. The horizontal slide plate is mounted on the frame and forms a horizontal sliding pair with the frame. The vertical slide plate is mounted on the horizontal slide plate and forms a vertical sliding pair with the horizontal slide plate. The drive motor is mounted on the horizontal slide plate and connected to the vertical slide plate, used to drive the vertical slide plate to slide vertically on the horizontal slide plate. The mounting base includes a vertical fixing plate and a horizontal fixing plate. One end of the vertical fixing plate is fixedly connected to the bottom end of the horizontal fixing plate. There are two connecting frames A, each including a first connecting frame unit and a second connecting frame unit, which are close to each other. The first connecting frame unit is rotatably connected to one end of the vertical slide plate at the end furthest from the second connecting frame unit, and to one end of the vertical fixed plate at the end furthest from the first connecting frame unit. The connecting shafts between the first and second connecting frame units, between the first and vertical slide plates, and between the second and vertical fixed plates are all vertically oriented. Two connecting frames A are symmetrically positioned on both sides of the vertical slide plate, with the horizontal fixed plate facing away from the vertical slide plate. A push-pull mounting base allows the connecting shafts between the first and second connecting frame units in the two connecting frames A to move synchronously closer or further away, adjusting the distance between the mounting base and the frame. A cutting motor is mounted on the horizontal fixed plate, and a saw blade is mounted on the output shaft of the cutting motor. The blade in this invention can move horizontally and vertically with the movement of the horizontal slide plate, vertical slide plate, and connecting frame A, allowing for linear cutting of different parts of the workpiece without moving the workpiece. This invention is convenient for cutting heavy workpieces that are difficult to move.

[0005] As a further improvement of the present invention, a connecting frame B is also included. Connecting frame B comprises a third connecting frame unit and a fourth connecting frame unit. The ends of the third and fourth connecting frame units close to each other are rotatably connected. The end of the third connecting frame unit away from the fourth connecting frame unit is rotatably connected to the vertical sliding plate. The end of the fourth connecting frame unit away from the third connecting frame unit is rotatably connected to the vertical fixing plate. The connecting shafts between the third and fourth connecting frame units, between the third connecting frame unit and the vertical sliding plate, and between the fourth connecting frame unit and the vertical fixing plate are all arranged in a horizontal direction. The present invention, by providing connecting frame B in conjunction with connecting frame A, makes the support and movement of the mounting base in the present invention more stable, thereby improving the cutting accuracy of the plate.

[0006] As a further improvement of the present invention, the second connecting frame unit and the fourth connecting frame unit have the same structure, each including two parallel connecting sleeves and at least one connecting rod A. The two ends of the connecting rod A are respectively fixedly connected to the two connecting sleeves. The first connecting frame unit and the third connecting frame unit have the same structure, each including two parallel connecting rods B. One end of each connecting rod B is located at one end of a connecting sleeve. The connecting rod B is mounted on the connecting sleeve by a screw passing through the connecting sleeve and the two connecting rods B, and nuts located at both ends of the screw. The screw is the connecting rod between the connecting sleeve and the connecting rod B. A connecting shaft is provided on the vertical slide plate, with a protrusion and a mounting through hole. The other end of the connecting rod B is located at both ends of the protrusion. The connecting rod B is mounted on the vertical slide plate by a screw passing through the mounting through hole and nuts at both ends of the connecting rod B. The screw is the connecting shaft between the connecting rod B and the vertical slide plate. A connecting ear plate is provided at each end of the connecting sleeve on the vertical fixing plate. The connecting ear plate is mounted on the connecting sleeve by a screw passing through the connecting sleeve and the two connecting ear plates, and nuts at both ends of the screw. The screw is the connecting shaft between the connecting sleeve and the connecting ear plate. This invention, through the connecting sleeve, protrusion, and connecting ear plates, facilitates the rotatable connection of the various parts of the connecting frame A and the connecting frame B, as well as the rotatable connection with the vertical slide plate and the mounting base.

[0007] As a further improvement of the present invention, a rotating seat is provided on the horizontal fixed plate. The rotating shaft of the rotating seat is arranged in the vertical direction. The cutting motor is mounted on the horizontal fixed plate by the rotating seat. The angle of the cutting motor is adjusted by the rotating seat to adjust the saw blade and change the cutting direction of the saw blade. The present invention provides a rotating seat, which changes the angle between the output shaft of the cutting motor and the frame, such as adjusting the output shaft of the motor to be parallel or perpendicular to the frame, so as to cut the plate along a direction perpendicular or parallel to the frame.

[0008] As a further improvement of the present invention, the frame includes two uprights, two horizontally arranged connecting beams, and one or more horizontally arranged guide rods. The two uprights are arranged in parallel, and their bottom ends are used for mounting on a fixed object. The two ends of the connecting beams are respectively fixedly connected to the upper part of the uprights. The two ends of the horizontal guide rods are respectively fixedly connected to the two uprights. A horizontal slider is provided on the horizontal slide plate, and the horizontal guide rod passes through the horizontal slider. The horizontal slide plate slides synchronously with the horizontal slider as it slides on the horizontal guide rod. The present invention facilitates the horizontal sliding connection between the horizontal slide plate and the frame in the horizontal direction through the cooperation of the horizontal guide rod and the horizontal slider.

[0009] As a further improvement of the present invention, a horizontal frame is fixed on the horizontal sliding plate. Two vertical guide rods and a lead screw are provided on the horizontal frame. The top and bottom ends of the vertical guide rods are fixedly connected to the horizontal frame, and the two ends of the lead screw are rotatably connected to the horizontal frame. The vertical sliding plate is provided with a vertical slider that cooperates with the vertical guide rods and a fixing block that threadedly engages with the lead screw. A drive motor is installed at the bottom end of the horizontal frame, and its output shaft is connected to the lead screw. The drive motor drives the lead screw to rotate, thereby driving the vertical sliding plate to move vertically on the horizontal frame. The present invention provides a horizontal frame to facilitate the sliding connection between the vertical and horizontal sliding plates. Through the cooperation of the vertical guide rods and the vertical sliders, the vertical sliding plate can slide vertically relative to the horizontal frame, thus achieving the purpose of vertical sliding of the vertical sliding plate relative to the horizontal sliding plate.

[0010] As a further improvement of the present invention, a vertical frame is fixed on the side of the vertical slide away from the horizontal slide, and the connecting frame A is rotatably connected to the upper part of the vertical frame. The present invention provides a vertical frame to facilitate rotatable connection with connecting frame A and connecting frame B.

[0011] As a further improvement of the present invention, a motor mounting plate is provided at the bottom of the horizontal frame, and the drive motor is mounted on the motor mounting plate. The present invention provides a motor mounting plate to facilitate the installation of the drive motor.

[0012] As a further improvement of the present invention, a fixing rod is fixed to the bottom of the column. This fixing rod is horizontally arranged and forms an inverted T-shape with the column, used to fix the column to the fixed object during use. The fixing rod in this invention increases the contact area between the frame and the fixed object during use, making the frame support more stable.

[0013] As a further improvement of the present invention, a reinforcing rod is provided on each of the lower two sides of the column. The reinforcing rods are inclined, and their two ends are fixedly connected to the column and the fixing rod, respectively. The reinforcing rods in this invention increase the connection strength between the column and the fixing rod.

[0014] In summary, the beneficial effects of the present invention are: the blade of the present invention can move in the horizontal and vertical directions as the horizontal slide plate, the vertical slide plate and the connecting frame A move, so that straight cutting can be performed on different parts of the work without moving the plate. The present invention is particularly convenient for cutting plates that are heavy and inconvenient to move. Attached Figure Description

[0022] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0023] like Figures 1 to 6The adjustable linear cutting machine shown includes a frame 1, a horizontal slide plate 2, a vertical slide plate 3, a drive motor 4, a mounting base 5, a connecting frame A8, and a cutting motor 11. The frame 1 is fixed to a fixed object during use. In this invention, the frame 1 is fixed to the ground during use. The horizontal slide plate 2 is mounted on the frame 1 and forms a horizontal sliding pair with the frame 1. The horizontal movement of the horizontal slide plate 2 is achieved by manual pushing. The vertical slide plate 3 is mounted on the horizontal slide plate 2 and forms a vertical sliding pair with the horizontal slide plate 2. In this invention, the drive motor 4 is mounted on the horizontal slide plate 2 and connected to the vertical slide plate 3. The drive motor 4 is used to drive the vertical slide plate 3 to slide vertically on the horizontal slide plate 2. The straight slide plate 3 moves synchronously with the horizontal slide plate 2 as the horizontal slide plate 2 slides horizontally. The mounting base 5 in this invention includes a vertical fixing plate 6 and a horizontal fixing plate 7. The end of the vertical fixing plate 6 near the frame 1 is fixedly connected to the bottom end of the horizontal fixing plate 7, making the longitudinal section of the entire mounting base 5 L-shaped. The vertical fixing plate 6 and the horizontal fixing plate 7 are integrally molded. There are two connecting frames A8 in this invention. Each connecting frame A8 includes a first connecting frame unit 9 and a second connecting frame unit 10. The ends of the first connecting frame unit 9 and the second connecting frame unit 10 that are close to each other are rotatably connected. The end of the first connecting frame unit 9 away from the second connecting frame unit 10 is connected to the vertical slide plate 3. One end of the second connecting frame unit 10 is rotatably connected to the end of the vertical fixing plate 6 away from the first connecting frame unit 9. The connecting shafts between the first connecting frame unit 9 and the second connecting frame unit 10, the connecting shaft between the first connecting frame unit 9 and the vertical slide plate 3, and the connecting shaft between the second connecting frame unit 10 and the vertical fixing plate 6 are all arranged in the vertical direction. The two connecting frames A8 are symmetrically arranged on both sides of the vertical slide plate 3, and the horizontal fixing plate 7 is located on the side away from the vertical slide plate 3. When the mounting base 5 is pushed or pulled, the connecting shafts connecting the first connecting frame unit 9 and the second connecting frame unit 10 in the two connecting frames A8 move closer or further away simultaneously to adjust the distance between the mounting base 5 and the frame 1. In this invention, when the connecting shafts of the first connecting frame unit 9 and the second connecting frame unit 10 move closer together, the distance between the mounting base 5 and the frame 1 increases; conversely, when the connecting shafts of the first connecting frame unit 9 and the second connecting frame unit 10 move further apart, the distance between the mounting base 5 and the frame 1 decreases. The cutting motor 11 is mounted on the horizontal fixed plate 7, and a saw blade 12 is mounted on the output shaft of the cutting motor 11. The cutting motor 11 slides horizontally in sync with the horizontal sliding plate 2, slides vertically in sync with the vertical sliding plate 3, and moves synchronously with the movement of the mounting base 5. The cutting motor 11 drives the saw blade 12 to rotate, and the plate is cut as the cutting motor 11 moves. The horizontal movement of the horizontal sliding plate 2 can also be achieved by a motor driving a lead screw threaded to the horizontal sliding plate.

[0024] The present invention includes a connecting frame B13, which comprises a third connecting frame unit 14 and a fourth connecting frame unit 15. The ends of the third connecting frame unit 14 and the fourth connecting frame unit 15 that are close to each other are rotatably connected. The end of the third connecting frame unit 14 that is away from the fourth connecting frame unit 15 is rotatably connected to the vertical sliding plate 3. The end of the fourth connecting frame unit 15 that is away from the third connecting frame unit 14 is rotatably connected to the vertical fixing plate 6. The connecting shafts of the third connecting frame unit 14 and the fourth connecting frame unit 15, the connecting shaft of the third connecting frame unit 14 and the vertical sliding plate 3, and the connecting shaft of the fourth connecting frame unit 15 and the vertical fixing plate 6 are all arranged in the horizontal direction.

[0025] The second connecting frame unit 10 and the fourth connecting frame unit 15 of this invention have the same structure, each including two parallel connecting sleeves 16 and at least one connecting rod A17. There are two connecting rods A17 in this invention, and they are arranged in parallel. The two ends of each connecting rod A17 are fixedly connected to the two connecting sleeves 16. The first connecting frame unit 9 and the third connecting frame unit 14 have the same structure, each including two parallel connecting rods B18. One end of each connecting rod B18 is located at both ends of the same connecting sleeve 16. The connecting rods B18 are mounted on the connecting sleeve 16 by a screw 20 passing through the connecting sleeve 16 and the two connecting rods B18, and nuts 21 located at both ends of the screw 20. Loosening the nuts 21 allows the connecting rods B18 to rotate relative to the connecting sleeves 16, while tightening the nuts 21 clamps the connecting rods B18 and the connecting sleeves 16. The connecting rod B18 and the connecting sleeve 16 can be fixed. The screw 20 here is the connecting shaft between the connecting sleeve 16 and the connecting rod B18. The present invention provides protrusions 19 on both sides and top of the vertical slide plate 3. The protrusions 19 are provided with mounting through holes (not shown in the figure). The other ends of the two connecting rods B18 are respectively located at the two ends of the protrusions 19. The connecting rods B18 are installed on the vertical slide plate 3 by the screw 20 passing through the mounting through holes and the connecting rods B18 and the nuts 21 at both ends of the connecting rods B18. The screw 20 is the connecting shaft between the connecting rods B18 and the vertical slide plate 3. The present invention provides a connecting ear plate 22 at each end of the connecting sleeve 16 on the vertical fixing plate 6. The connecting ear plate 22 is installed on the connecting sleeve 16 by the screw 20 passing through the connecting sleeve 16 and the two connecting ear plates 22 and the nuts 21 at both ends of the screw 20. The screw 20 is the connecting shaft between the connecting sleeve 16 and the connecting ear plate 22.

[0026] The present invention provides a rotating seat 23 on a horizontal fixed plate 7. The rotating shaft of the rotating seat 23 is arranged in the vertical direction. The rotating seat 23 in the present invention is prior art and will not be described in detail. The cutting motor 11 is mounted on the horizontal fixed plate 7 by the rotating seat 23. The angle of the cutting motor 11 is adjusted by the rotating seat 23 to adjust the saw blade 12 to change the cutting direction of the saw blade 12.

[0027] The frame 1 of this invention includes two uprights 24, two horizontally arranged connecting beams 25, and one or more horizontally arranged guide rods 26. The two uprights 24 are arranged parallel to each other in the vertical direction, and the bottom end of the uprights 24 is used to install on a fixed object (i.e., the ground). The two ends of the connecting beams 25 are respectively fixedly connected to the upper part of the uprights 24. This invention is provided with two horizontal guide rods 26, which are parallel to the connecting beams 25 and located between the two connecting beams 25. The two ends of the horizontal guide rods 26 are respectively fixedly connected to the two uprights 24. A horizontal slider 27 is detachably installed on the horizontal slide plate 2 using bolts. The horizontal guide rods 26 pass through the horizontal slider 27, so that the horizontal slider 27 can slide horizontally along the length direction of the horizontal guide rods 26. The horizontal slide plate 2 slides synchronously with the horizontal slider 27 sliding on the horizontal guide rods 26.

[0028] In this invention, a horizontal frame 28 is welded and fixed on the side of the horizontal slide plate 2 away from the connecting beam 25. The horizontal frame 28 is rectangular and has two vertical guide rods 29 and a lead screw 30. The lead screw 30 is located between the two vertical guide rods 29 and is parallel to them. The top and bottom ends of the vertical guide rods 29 are fixedly connected to the horizontal frame 28. The top and bottom ends of the lead screw 30 are rotatably connected to the horizontal frame 28 by bearings. A vertical slider that cooperates with the vertical guide rods 29 and a fixing block that is threadedly engaged with the lead screw 30 are provided on the vertical slide plate 3. A drive motor 4 is installed at the bottom end of the horizontal frame 28, and its output shaft is connected to the bottom end of the lead screw 30 by a coupling. The drive motor 4 drives the lead screw 30 to rotate, thereby driving the vertical slide plate 3 to move vertically along the vertical guide rods 29 on the horizontal frame 28. In this invention, a vertical frame 31 is fixed on the side of the vertical slide plate 3 away from the horizontal slide plate 2. The vertical frame 31 is rectangular, and the connecting frame A8 is rotatably connected to the upper part of the vertical frame 31. A motor mounting plate 32 is provided at the bottom of the horizontal frame 28, and the drive motor 4 is mounted on the motor mounting plate 32. The motor mounting plate 32 facilitates the installation of the drive motor 4.

[0029] The present invention has a fixing rod 33 fixed at the bottom of the column 24. The fixing rod 33 is horizontally set and welded to the column 24 to form an inverted T-shaped structure. The fixing rod 33 is used to fix the column 24 to the fixed object (i.e. the ground) in the use state. The present invention has a reinforcing rod 34 on each side of the lower part of the column 24. The reinforcing rod 34 is inclined and its two ends are welded to the column 24 and the fixing rod 33 respectively.

[0030] This invention provides a support platform located below the saw blade 12 for placing the board to be cut. In use, the board is placed on the support platform. If cutting is required along a direction parallel to the connecting beam 25, the rotating seat 23 is adjusted so that the output shaft of the cutting motor 11 is perpendicular to the connecting beam 25, thus making the saw blade 12 parallel to the connecting beam 25. Then, by rotating the connecting bracket A8 and connecting bracket B13, the position of the saw blade 12 is adjusted to above the part of the board to be cut. The drive motor 4 then lowers the saw blade 12, and the horizontal sliding plate 2 is moved horizontally to cut the board. If cutting is required along a direction perpendicular to the connecting beam 25, the rotating seat 23 is first adjusted to make the saw blade 12 perpendicular to the connecting beam 25, then the vertical sliding plate 3 is adjusted downwards, and finally, the mounting seat 5 is pushed towards the connecting beam 25 to complete the straight-line cutting of the board.

[0031] Unless otherwise specified in the above description, all parts are prior art, or can be implemented using existing technology. Furthermore, the specific embodiments described in this invention are merely preferred embodiments and are not intended to limit the scope of this invention. That is, all equivalent changes and modifications made within the scope of this invention should be considered within the technical scope of this invention.
