Description

Technical Field

[0001] This invention relates to the field of cutting tooling technology, and more specifically to an automatic cutting tooling. Background Technology

[0002] Any cutting process requires three basic conditions: a cutting tool, a workpiece, and a cutting motion, known as the three elements of cutting. The cutting tool must have a cutting edge, and its material must be harder than the workpiece. Different tool structures and cutting motions constitute different cutting methods. Methods using tools with fixed cutting edge shapes and numbers include turning, drilling, boring, milling, planing, broaching, and sawing; methods using grinding wheels or abrasives with variable cutting edge shapes and numbers include grinding, lapping, honing, and polishing.

[0003] Cutting is a machining process that uses cutting tools (including cutting tools, grinding wheels and abrasives) to remove excess material layers from a blank or workpiece, resulting in chips, so that the workpiece obtains a specified geometric shape, size and surface quality.

[0004] Traditional cutting fixtures cut the workpiece from the same position, and the tooling operator cannot adjust the position of the clamping mechanism on the fixture for adjustment, which reduces the practicality of the fixture. In addition, the cutting fixtures commonly seen on the market are convenient for clamping taller workpieces, but generally cannot clamp shorter workpieces stably. Therefore, designing an automatic cutting fixture has become an urgent problem to be solved. Summary of the Invention

[0005] The main technical problem solved by this invention is to provide an automatic cutting fixture that can solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, more specifically, an automatic cutting fixture includes a worktable, a housing, and a vertical plate. The worktable is fixedly connected to the upper surface of the housing. The vertical plate is fixedly connected to the rear edge of the upper surface of the worktable. A longitudinal electric slide rail is fixedly connected to the center of the front surface of the vertical plate. A transverse electric slide rail is slidably connected to the front of the longitudinal electric slide rail. An electric slider is slidably connected to the front of the transverse electric slide rail. An electric push rod is fixedly connected to the front surface of the electric slider by bolts. A U-shaped mounting bracket is fixedly connected to the bottom end of the electric push rod. A drive motor is fixedly connected inside the U-shaped mounting bracket. A cutter head is installed at the bottom of the output end of the drive motor. Two elongated slots are integrally formed on the upper surface of the worktable. A round rod extends through the left and right sides of the interior of each elongated slot. A top plate is fixedly connected to the top ends of the two round rods on the left side, and a top plate is also fixedly connected to the top ends of the two round rods on the right side. A connecting post is integrally formed at the bottom end of each round rod. A connecting post is rotatably connected to the outer wall of the connecting post. A concave plate No. 1 has a cylindrical rod fixedly connected to its lower surface. A concave plate No. 2 is fixedly connected to the bottom end of the cylindrical rod. A transmission rod is rotatably connected to the inner wall of the concave plate No. 2 via a rotating shaft. There are four transmission rods in total. A first disc is mounted on the side of the two outermost transmission rods, and a motor No. 1 is mounted on the side of the first disc. A second disc No. 1 is mounted on the side of the two middle transmission rods, and a motor No. 3 is mounted on one side of the second disc No. 1. A motor base is fixedly connected to the lower surface of the motor No. 1. Two... A square movable rod is fixedly connected to the opposite side of the motor base. A horizontal plate is fixedly connected to the upper interior of the housing. A second motor is fixedly connected to the upper left side of the interior of the housing. A lead screw is fixedly connected to the output end of the second motor. A lead screw seat is movably connected to the outer side wall of the second motor, and the bottom end of the lead screw seat contacts the upper surface of the horizontal plate. Support blocks are fixedly connected to the left and right sides of the upper surface of the lead screw seat. The square movable rod is slidably connected to the top of each support block. An expansion mechanism is installed between two square movable rods.

[0007] Furthermore, the expansion mechanism includes a miniature electric push rod, a second disc, a support plate, a vertical rod, a horizontal bar, a connecting block, a transmission rod number two, a transmission rod number three, a fixing block, a transmission rod number four, and a push rod. The miniature electric push rod is fixedly connected to the middle of the upper surface of the lead screw seat. The push rod is fixedly connected to the top of the miniature electric push rod. The horizontal bar is fixedly connected to the top of the push rod. The transmission rod number four is rotatably connected to the left and right sides of the front surface of the horizontal bar. The transmission rod number three is rotatably connected to the rear surface of the transmission rod number four. The fixing block is rotatably connected above the rear surface of the transmission rod number three. The transmission rod number two is rotatably connected to one side of the front surface of the fixing block. The connecting block is rotatably connected to the rear of the connecting block and the transmission rod number three. The vertical rod is fixedly connected to one side of the lower surface of the connecting block. The support plate is fixedly connected to the lower surface of the vertical rod. The second disc, the second disc, is fixedly connected to the lower surface of the support plate and is fixed to the lead screw seat.

[0008] Furthermore, the push rod is externally fitted with the support plate and the second disk, and both the second disk and the support plate are slidably connected to the push rod.

[0009] Furthermore, one side of the lower surface of the square movable rod is fixed to the upper surface of the fixed block.

[0010] Furthermore, the round rod is fixedly connected to the front left side of the lower surface of each of the top plates and the rear right side of the lower surface of each of the top plates, and the center of the second disk coincides with that of the first disk.

[0011] Furthermore, a spring is fitted on the upper part of each of the round rods, and a base plate is fitted on the outer part of the two round rods in the front-rear direction near the lower part of the spring, and the upper surface of the base plate is in contact with the upper surface of the worktable.

[0012] Furthermore, the front surface of the housing is connected to door panels on both the left and right sides via hinges.

[0013] Furthermore, a control system is provided on the left side of the upright plate. The control system is fixedly connected to the upright plate and electrically connected to the longitudinal electric slide rail, the transverse electric slide rail, the second motor, the electric push rod, the drive motor, the miniature electric push rod, the third motor, and the first motor.

[0014] Furthermore, a workpiece is held between the two top plates, and the workpiece is detachably connected to the top plates.

[0015] The beneficial effects of the automatic cutting fixture of the present invention are as follows:

[0016] The designed cutting fixture features an adjustable cutter head, allowing for horizontal and vertical position adjustments. Operators can adjust the cutter head to the left, center, or even right depending on the work requirements. This adjustment also allows for adjustment of the clamping mechanism. Through the control system, the operator can move the lead screw seat horizontally, thereby moving the components on the lead screw. When motors one and three are running, the two output shafts move in opposite directions. Through the transmission rod, concave plate two, cylindrical rod, concave plate one, and connecting column, the cylindrical rod can move vertically. Since the base plate contacts the worktable, the top plate can move downwards towards the worktable or upwards. The top plate is positioned lower than the workpiece height by adjusting its height, allowing it to contact different workpieces. Furthermore, when the miniature electric actuator moves upwards, transmission rod number four moves upwards, pushing the lower part of transmission rod number three outwards, bringing the two fixed blocks closer together. This allows the square moving rod to slide on the support pier. Because motors number one and three are connected to the base plate, the top plates at the top can move away from each other, allowing the workpiece to be placed between them and clamped. The designed cutting fixture can clamp workpieces of different sizes and thicknesses, and the workpiece position can be adjusted arbitrarily. It is simple and convenient to operate, and highly functional. Attached Figure Description

[0025] According to the present invention Figure 1-5As shown, an automatic cutting fixture is provided, including a worktable 10, a housing 16, and a vertical plate 42. The worktable 10 is fixedly connected to the upper surface of the housing 16, and the vertical plate 42 is fixedly connected to the rear edge of the upper surface of the worktable 10. A longitudinal electric slide rail 1 is fixedly connected to the middle of the front surface of the vertical plate 42. A transverse electric slide rail 3 is slidably connected to the front of the longitudinal electric slide rail 1, and an electric slider 2 is slidably connected to the front of the transverse electric slide rail 3.

The internal drive motor 6 is fixedly connected to the U-shaped mounting bracket 5. A cutter head 7 is installed at the bottom of the output end of the drive motor 6. The upper surface of the worktable 10 has two integrally formed long slots 9. A round rod 19 runs through the left and right sides of the interior of each long slot 9. A top plate 8 is fixedly connected to the top of the two round rods 19 on the left side, and a top plate 8 is also fixedly connected to the top of the two round rods 19 on the right side. A connecting post 20 is integrally formed at the bottom of each round rod 19. A concave plate 21 is rotatably connected to the outer wall of the connecting post 20. The lower surface of the concave plate 21 is fixed. A cylindrical rod 22 is connected, and a concave plate 23 is fixedly connected to the bottom end of the cylindrical rod 22. A transmission rod 24 is rotatably connected to the inner wall of the concave plate 23 via a rotating shaft. There are four transmission rods 24 in total. A first disc 25 is mounted on the side of the two outer transmission rods 24, and a motor 26 is mounted on the side of the first disc 25. A second disc 45 is mounted on the side of the two middle transmission rods 24, and a motor 43 is mounted on one side of the second disc 45. A motor base 27 is fixedly connected to the lower surface of the motor 26. The two motor bases 27 are positioned opposite each other. A square moving rod 28 is fixedly connected to the side. A horizontal plate 13 is fixedly connected to the upper part of the inside of the box 16. A motor 40 is fixedly connected to the upper left side of the inside of the box 16. A lead screw 14 is fixedly connected to the output end of the motor 40. A lead screw seat 12 is movably connected to the outer wall of the motor 40, and the bottom end of the lead screw seat 12 is in contact with the upper surface of the horizontal plate 13. Support blocks 11 are fixedly connected to the left and right sides of the upper surface of the lead screw seat 12. A square moving rod 28 is slidably connected to the top of each support block 11. An expansion mechanism 44 is installed between two square moving rods 28.

[0026] In this embodiment, the expansion mechanism 44 includes a miniature electric push rod 29, a second disc 30, a support plate 31, a vertical rod 32, a horizontal bar 33, a connecting block 34, a transmission rod 35, a transmission rod 36, a fixing block 37, a transmission rod 38, and a push rod 39. The miniature electric push rod 29 is fixedly connected to the middle of the upper surface of the lead screw seat 12. The top of the miniature electric push rod 29 is fixedly connected to the push rod 39. The top of the push rod 39 is fixedly connected to the horizontal bar 33. The left and right sides of the front surface of the horizontal bar 33 are rotatably connected to the transmission rod 38. The rear surface of the transmission rod 38 is rotatably connected to the transmission rod 36. The fixing block 37 is rotatably connected above the rear surface of the transmission rod 36. One side of the front surface of the fixing block 37 is rotatably connected to the transmission rod 35. The rear surface of the transmission rod 35 is rotatably connected to the transmission rod 35. A connecting block 34 is connected, and the rear of the connecting block 34 is rotatably connected to the transmission rod 36. A vertical rod 32 is fixedly connected to one side of the lower surface of the connecting block 34. A support plate 31 is fixedly connected to the lower surface of the vertical rod 32. A second disc 30 is fixedly connected to the lower surface of the support plate 31, and the second disc 30 is fixed to the lead screw seat 12. The output end of the micro electric push rod 29 can be extended or shortened. When the output shaft of the micro electric push rod 29 is shortened, the push rod 39 moves downward, pulling the transmission rod 38 downward. At this time, the lower halves of the two transmission rods 36 move closer to each other, and the two fixed blocks move further away from each other, so that the two square moving rods 28 move further away from each other, thereby causing the two top plates 8 to move further away from each other. Different workpieces can be clamped between the top plates 8, and the left and right sides of the workpiece contact the top plates 8.

[0027] In this embodiment, a support plate 31 and a second disc 30 are sleeved on the outside of the push rod 39, and the second disc 30 and the support plate 31 are slidably connected to the push rod 39. The support plate 31 is fixed above the lead screw seat 12, and the push rod 39 can move in the vertical direction.

[0028] In this embodiment, one side of the lower surface of the square movable rod 28 is fixed to the upper surface of the fixed block 37. When the fixed block 37 moves, the square movable rod 28 will move.

[0029] In this embodiment, a round rod 19 is fixedly connected to the left front of the lower surface of each top plate 8 and the right rear of the lower surface of each top plate 8. The center of the second disc 45 coincides with that of the first disc 25. There are two round rods 19 under each top plate 8. When the round rod 19 moves downward, the spring 17 is compressed.

[0030] In this embodiment, a spring 17 is sleeved on the upper part of each round rod 19. A base plate 18 is sleeved on the outer part of the two round rods 19 in the front-back direction near the lower part of the spring 17. The upper surface of the base plate 18 is in contact with the upper surface of the worktable 10. The two base plates 18 can move closer to each other or further away from each other. In addition, the two base plates 18 can move simultaneously, moving to the left or to the right together.

[0031] In this embodiment, door panels 15 are rotatably connected to the left and right sides of the front surface of the box 16 via hinges, and the interior of the box 16 can be used as storage space.

[0032] In this embodiment, a control system 41 is provided on the left side of the upright plate 42. The control system 41 is fixedly connected to the upright plate 42. The control system 41 is electrically connected to the longitudinal electric slide rail 1, the transverse electric slide rail 3, the second motor 40, the electric push rod 4, the drive motor 6, the micro electric push rod 29, the third motor 43, and the first motor 26. The control system 41 serves as the brain of the cutting tooling.

[0033] In this embodiment, a workpiece is held between two top plates 8, and the workpiece is detachably connected to the top plates 8.

[0034] The working principle of this device is as follows: First, when using the device, check whether the control system 41 of the tooling is powered. The control system 41 is electrically connected to an external power source. The cutter head 7 on the tooling can be adjusted in both the horizontal and vertical directions. The tooling operator can adjust the cutter head 7 to the left, middle, or even right according to the working conditions. Furthermore, the adjustment of the cutter head 7 means that the clamping mechanism can also be adjusted. Through the control system 41, the operator can realize the horizontal movement of the lead screw seat 12, thereby moving the components on the lead screw 14. When motor 1 26 and motor 3 43 are running, the two output shafts move in opposite directions. Through the operation of the transmission rod 24, concave plate 23, cylindrical rod 22, concave plate 21, and connecting column 20, the cylindrical rod 19 can be moved in the horizontal direction. In the vertical direction, since the base plate 18 contacts the worktable 10, the top plate 8 can move downwards closer to the worktable 10 or upwards away from the worktable 10. By adjusting its height, the position of the top plate 8 is lower than the height of the workpiece, which can contact different workpieces. In addition, when the micro electric push rod 29 is running, the push rod 39 moves upwards, the transmission rod 4 38 moves upwards, and pushes the lower part of the transmission rod 3 36 to move outwards, which can bring the two fixed blocks 37 closer to each other. Then the square moving rod 28 slides on the support block 11. Since the base plate 18 is connected to the motor 1 26 and the motor 3 43, the top plate 8 at the top can move away from each other, which can clamp the workpiece between the two. Then the cutter head 7 moves downwards after adjusting its position, which can drill holes in the workpiece.

[0035] All electrical components mentioned in this article are real-world electrical components.

[0036] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
