Description

Technical Field

[0001] This utility model relates to the field of gantry planer technology, specifically a gantry planer capable of bidirectional planing. Background Technology

[0002] Gantry planers are mainly used for planing large workpieces. They can also clamp multiple parts on the worktable for simultaneous processing, making them the mother machine of industry. The worktable of the gantry planer carries the workpiece in a linear reciprocating motion through a gantry frame, with the idle stroke speed exceeding the working stroke speed. A vertical tool post is generally mounted on the crossbeam. The tool post slide can rotate at an angle in the vertical plane and can make transverse feed movements along the crossbeam to achieve cutting of large workpieces.

[0003] As proposed in authorization announcement number CN220943363U, a speed-adjustable gantry planer includes a support plate. Two fixed plates are fixedly installed on the top of the support plate and are arranged opposite to each other. A groove is provided on one side of each of the two fixed plates, and a screw is movably connected inside the groove. This gantry planer facilitates the replacement of the planer tool and is equipped with an avoidance structure to prevent the drill bit from colliding with the workpiece during planer operation.

[0004] However, the aforementioned gantry planer still has certain shortcomings in its application. When the gantry planer performs planing, the workpiece reciprocates once, and the planer only contacts the workpiece during the forward stroke. During the return stroke, the workpiece faces the back of the planer and cannot be planed during the return stroke. This processing method is not only inefficient but also wastes time. In addition, the aforementioned gantry planer can only perform planing on a horizontal plane and cannot perform side planing on the workpiece, making it difficult to meet the different processing requirements of the workpiece. In order to address the above problems, we provide a gantry planer that can perform bidirectional planing to solve the aforementioned issues. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 In this embodiment of the utility model, a gantry planer capable of bidirectional planing includes a hollow bed 1, the bottom of which is provided with a plurality of support legs. Please see Figure 7 and Figure 8 A planing worktable 2 is provided above the hollow bed 1. Inside the hollow bed 1 is a moving assembly for driving the planing worktable 2 to move along the hollow bed 1. The moving assembly includes two side slide rails 23, which are fixedly connected to the two sides inside the hollow bed 1. L-shaped slide blocks 27 are fixedly connected to both sides of the lower end face of the planing worktable 2, and the L-shaped slide blocks 27 are slidably connected to the side slide rails 23. A strip-shaped shell 24 is fixedly connected to one side inside the hollow bed 1. A third threaded rod 25 is rotatably connected inside the strip-shaped shell 24. A mountain-shaped slider 26 is threaded onto the third threaded rod 25. The slider 26 is slidably connected to the strip shell 24. The upper ends of both sides of the mountain-shaped slider 26 are fixedly connected to the planing table 2. One end of the hollow bed 1 is also provided with a third servo motor 9 for driving the third threaded rod 25 to rotate. When the planing table 2 is driven to move, the third servo motor 9 drives the third threaded rod 25 to rotate. The rotation of the third threaded rod 25 drives the mountain-shaped slider 26 to move. The movement of the mountain-shaped slider 26 can drive the planing table 2 to move along the side slide rail 23. The strip shell 24 can shield and protect the third threaded rod 25 to prevent metal chips generated during planing from falling onto the position of the third threaded rod 25 and affecting the transmission.

[0027] Please see Figure 8The hollow bed body 1 is fixedly connected with a retaining edge at the position above the side slide rail 23 on the inner side; the retaining edge can block the area above the side slide rail 23 to prevent the chips generated by planing from falling onto the side slide rail 23 and affecting the sliding of the L-shaped slide 27.

[0028] Please see Figure 1 and Figure 4 A gantry frame 4 is fixedly connected to the middle of the hollow bed body 1. A vertical box 7 is provided on one side of the crossbeam of the gantry frame 4. A lateral movement assembly for driving the vertical box 7 to move laterally is provided on the upper crossbeam of the gantry frame 4. The lateral movement assembly includes a convex slide groove 8, which is opened at the position of the upper crossbeam of the gantry frame 4. A convex slider 10 is slidably connected in the convex slide groove 8. The convex slider 10 is fixedly connected to the vertical box 7. A first threaded rod 16 is rotatably connected inside the convex slide groove 8. The first threaded rod 16 is threadedly connected to the convex slider 10. A first servo motor 5 is provided at one end of the gantry frame 4 for driving the first threaded rod 16 to rotate. When driving the vertical box 7 to move laterally, the first servo motor 5 drives the first threaded rod 16 to rotate. The rotation of the first threaded rod 16 can drive the convex slider 10 to move along the convex slide groove 8. The movement of the convex slider 10 can drive the vertical box 7 to move accordingly.

[0029] Please see Figure 2 , Figure 3 and Figure 5 The vertical box 7 has a sliding inner box 11 slidably connected inside it. The vertical box 7 is equipped with a lifting assembly that drives the sliding inner box 11 to move up and down. The lifting assembly includes a second threaded rod 17, which is located inside the vertical box 7. The upper end of the second threaded rod 17 is rotatably connected to the vertical box 7. A threaded sleeve is fixedly connected to the middle of the upper end of the sliding inner box 11. The second threaded rod 17 is threadedly connected to the threaded sleeve. A second servo motor 6 is installed in the middle of the upper end of the vertical box 7 to drive the second threaded rod 17 to rotate. When the sliding inner box 11 is raised or lowered, the second servo motor 6 drives the second threaded rod 17 to rotate. The rotation of the second threaded rod 17 can drive the sliding inner box 11 to slide inside the vertical box 7, thereby realizing the adjustment of the height of the sliding inner box 11.

[0030] Please see Figure 6The lower end of the sliding inner box 11 is rotatably connected to a planer head box 3 via a rotating shaft. The planer head box 3 contains a planing assembly for bidirectional planing. The planing assembly includes racks 19, which are slidably connected to both sides inside the planer head box 3. A gear 20 is rotatably connected to the center of the planer head box 3, and the gear 20 meshes with two racks 19 on each side. The lower ends of the racks 19 extend out of the planer head box 3, and each end extending out of the planer head box 3 is fixedly connected to a mounting sleeve 14. Planing blades 13 are inserted into each mounting sleeve 14, with the two planing blades 13 cutting in opposite directions. Each mounting sleeve 14 has a locking screw 12 on one side for fixing the planing blades 13. The planer head box 3 has an electric motor on one side for driving one side of the racks 19 to move up and down. The electric cylinder 15, through the two racks 19 and the gear 20, allows the two planer blades 13 to be staggered, one high and one low. During the planing process, one planer blade 13 contacts the workpiece and performs planing. When the workpiece returns, the output end of the electric cylinder 15 moves one rack 19, which drives the gear 20 to rotate. The rotation of the gear 20 can switch the other planer blade 13 to the planing position, so that the other planer blade 13 contacts the workpiece during the return stroke and performs planing, thus realizing bidirectional planing, which can effectively improve processing efficiency. When the planer blade 13 needs to be replaced, the locking screw 12 can be loosened or unscrewed, and then the planer blade 13 can be pulled out from the mounting sleeve 14 for replacement. After replacement, the locking screw 12 can be tightened to fix the replaced planer blade 13.

[0031] Please see Figure 3 , Figure 5 and Figure 6 The lower end of the sliding inner box 11 is also provided with an adjustment component for adjusting the planing angle. The adjustment component includes a threaded post 21, which is fixedly connected to the lower end of the planer head box 3 near the sliding inner box 11. A turntable is fixedly connected to the lower end of the sliding inner box 11. The turntable is concentric with the rotating shaft at the lower end of the sliding inner box 11. An adjustment arc groove 18 is provided on the turntable. A locking nut 22 is threadedly connected to the position where the threaded post 21 passes through the adjustment arc groove 18. When it is necessary to adjust the planing angle, the locking nut 22 can be loosened first, and then the planer head box 3 can be rotated to adjust the angle. After the adjustment is completed, the locking nut 22 can be tightened. This allows for horizontal planing, side planing of the workpiece, and planing at other angles within the adjustment range, which can meet different processing requirements of the workpiece.

[0032] The working principle of this utility model is as follows: During processing, the required workpiece is first fixed on the planing worktable 2. Then, the height of the planer head box 3 is adjusted according to the height of the workpiece. During adjustment, the second servo motor 6 drives the second threaded rod 17 to rotate. The rotation of the second threaded rod 17 can drive the sliding inner box 11 to slide within the vertical box 7, thereby realizing the adjustment of the height of the sliding inner box 11. Then, the lateral position of the planer head box 3 is adjusted by the transverse component so that the tool reaches the planing position. During planing, the third servo motor 9 drives the third threaded rod 25 to rotate. The rotation of the third threaded rod 25 drives the mountain-shaped slider 26 to move. The movement of the mountain-shaped slider 26 can drive the planing worktable 2 to move along the side slide rail 23. By controlling the forward and reverse rotation of the third servo motor 9, the planing worktable 2 can drive the workpiece to reciprocate. When the planing table 2 reciprocates, the workpiece can contact the two planing cutters 13 respectively, thereby realizing bidirectional planing. Specifically, when the planing table 2 moves the workpiece forward, one planing cutter 13 contacts the workpiece for planing. When the workpiece returns, the third servo motor 9 switches its direction, driving the third threaded rod 25 to reverse, causing the planing table 2 to return. When the third servo motor 9 switches its direction, the output end of the electric cylinder 15 moves synchronously, driving one rack 19 to move. The rack 19 drives the gear 20 to rotate. Through the rotation of the gear 20, the other planing cutter 13 can be switched to the planing position, so that the other planing cutter 13 contacts the workpiece for planing during the return stroke. During planing, the planing head box 3 can be moved accordingly in conjunction with the transverse component and the lifting component to realize the planing processing of the workpiece.

[0033] It should also be noted that this application uses a programmable logic controller (PLC) for control. The control and circuit wiring of the servo motor and electric cylinder are common knowledge in this technical field. Those skilled in the art can simply edit them according to production needs, so no further details are provided here.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
