Description

Technical Field

[0001] This invention belongs to the field of machining technology, and specifically relates to a machining corner cutting device. Background Technology

[0002] In the field of machining, workpiece corner cutting often involves angle cutting on both horizontal and vertical planes (such as corner cutting of frame-like workpieces, multi-faceted chamfering of irregularly shaped components, etc.). However, existing corner cutting equipment has significant technical limitations: its angle adjustment function is mostly limited to a single plane, either only able to adjust the angle of the workpiece or corner saw in the horizontal plane, or only able to complete the tilting cut of the corner saw in the vertical plane, and cannot achieve coordinated adjustment of the "horizontal-vertical" dual planes. Specifically, when processing workpieces that require both horizontal and vertical chamfering, operators must complete the process in two steps: First, the workpiece is fixed on the worktable to complete the chamfering process in the horizontal plane; second, the processed portion must be manually disassembled, the workpiece's posture readjusted (e.g., flipping the original vertical plane to the horizontal plane), and clamped and fixed again before the equipment can be started to complete the chamfering process in the vertical plane. This "single-time processing of a single plane, multi-plane processing of multiple steps" mode not only leads to a cumbersome processing flow and extended operation time, but also causes positioning deviations due to repeated workpiece fixing. The reference points for the two fixings are difficult to be completely consistent, easily causing dimensional misalignment and angular deviations between horizontal and vertical chamfering, ultimately affecting the workpiece assembly accuracy. At the same time, repeated manual loading and unloading of workpieces increases labor intensity, and there is a risk of workpiece damage during flipping and handling, further reducing processing efficiency and finished product qualification rate, making it difficult to meet the modern machining production requirements of "high efficiency, precision, and integration". In view of this, this invention proposes a machining chamfering device. Summary of the Invention

[0003] To address the aforementioned shortcomings in the existing technology, the present invention provides a machining corner cutting device, comprising a base, a machining table mounted on the base, a clamping device embedded in the top of the machining table, and a corner cutting saw mounted on the base. The bottom of the corner cutting saw is connected to a Y-axis moving component, a vertical rotating component is mounted at the lower end of the corner cutting saw, an X-axis moving component is provided in the middle, and a horizontal rotating component is mounted on the clamping device. The Y-axis moving assembly includes two slide rails that are parallel to each other and mounted on the upper surface of the base. The upper end of the slide rails is movably connected to a pulley. The pulley is rotatably mounted on the lower end of the mounting plate. A threaded block is fixedly mounted on the lower surface of the mounting plate. The threaded block is screwed into a first lead screw through a thread. Both ends of the first lead screw are rotatably connected to a limiting plate fixedly mounted on the base. One end of the first lead screw is connected to the shaft of a third motor. The third motor is detachably mounted on the upper surface of the base. Secondly, the vertical rotation assembly includes a second mounting base fixedly mounted on the upper surface of the mounting plate, and the upper end of the second mounting base is fixedly connected to the shaft of a second motor fixedly mounted on the bottom of the corner saw.

[0004] Meanwhile, the X-axis moving assembly includes a third mounting base mounted on the upper end of the seventh motor. A fourth motor is detachably mounted on the top of the third mounting base. The rotating shaft of the fourth motor is connected to a second worm gear. The second worm gear is meshed with a first worm wheel. The first worm wheel is fixedly mounted on a support rod. The middle part of the support rod is rotatably connected to a support plate fixedly mounted on the top of the third mounting base. Second worm wheels are also fixedly mounted on both ends of the support rod. The second worm wheels are meshed with two first worm gears that are threadedly connected to the upper end of the third mounting base.

[0005] The first worm gear has a first mounting base installed at its rear end, and a first motor is provided at the upper end of the first mounting base. The rotating shaft of the first motor is rotatably connected to the bottom of the corner saw.

[0006] Furthermore, the horizontal rotation assembly includes a fixed box embedded in the processing table. A fifth motor and a sixth motor are detachably installed at the bottom of the fixed box. A first spur gear is fixedly installed on the shaft of the fifth motor. The first spur gear meshes with a second spur gear fixedly installed at the lower end of the connecting rod. The upper end of the connecting rod is fixedly connected to the top of the clamping worktable. The lower surface of the clamping worktable is in contact with the upper surface of the fixed box.

[0007] Secondly, the clamping device includes a third spur gear fixedly mounted on the shaft of the sixth motor, which meshes with a fourth spur gear fixedly mounted on the bottom of the sleeve. The sleeve is fitted onto the outer wall of the connecting rod, and a first bevel gear is mounted on the upper end of the sleeve.

[0008] Secondly, the clamping device also includes two sliding grooves opened along the same straight line on the upper end of the clamping worktable. A clamping plate is slidably connected in the sliding groove. The bottom of the clamping plate is screwed to a second lead screw. A second bevel gear is fixedly installed on one end of the second lead screw near the center of the clamping worktable. The second bevel gear meshes with the first bevel gear.

[0009] Furthermore, two conical positioning plates are installed on the left end of the processing table. The tips of the two conical positioning plates are arranged radially, and there is a gap between the two tips that is greater than the thickness of the corner saw blade, which is conducive to the corner saw cutting and prevents damage to the equipment.

[0010] Furthermore, a rotating groove is provided on the conical positioning plate, which is beneficial to the operation of the horizontal rotating component.

[0011] The bottom of the processing table is equipped with support legs.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention achieves integrated dual-plane corner cutting, simplifying the processing flow: Through the collaborative design of a "horizontal rotation component + vertical rotation component," dual-plane corner cutting can be completed without disassembling and flipping the workpiece. The horizontal rotation component can drive the clamped workpiece to flexibly adjust its angle in the horizontal plane to meet horizontal corner cutting requirements; the vertical rotation component can drive the corner saw to adjust its tilt angle in the vertical plane, adapting to vertical corner cutting. The two components work together to simultaneously or continuously complete the horizontal and vertical plane corner cutting of the workpiece, completely eliminating the tedious steps of "disassembly-flipping-re-fixing," simplifying multi-step processing into a single clamping operation, and significantly shortening the processing cycle. 2. Eliminate repetitive positioning deviations and improve machining accuracy: Since the workpiece only needs to be clamped once to complete the double-plane corner cutting, the problem of datum misalignment caused by multiple fixations is avoided. The clamping device achieves stable clamping through gear-screw transmission, ensuring that the workpiece maintains accurate positioning throughout the horizontal rotation and vertical corner cutting process; at the same time, the X-axis and Y-axis moving components achieve millimeter-level adjustment through screw-worm gear transmission, further ensuring the relative positional accuracy between the corner saw and the workpiece, keeping the dimensional and angular deviations of the horizontal and vertical corner cutting within a very small range, and significantly improving the workpiece assembly adaptability.

[0019] Example 1: like Figure 1-7 As shown in the accompanying drawings, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] I. Equipment Assembly (1) Implementation of Y-axis moving component Two slide rails 17 are installed parallel to each other on the upper surface of the base 1. The upper end of the slide rails 17 is movably connected to the pulley 16. The pulley 16 is rotatably installed on the lower end of the mounting plate 11. A threaded block 14 is fixedly installed on the lower surface of the mounting plate 11. The threaded block 14 is screwed into the first lead screw 13. Both ends of the first lead screw 13 are rotatably connected to the limiting plate 15, and one end is connected to the shaft of the third motor 12. The third motor 12 is installed on the upper surface of the base 1. When the third motor 12 is started, it drives the first lead screw 13 to rotate. The threaded block 14 moves axially along the first lead screw 13, causing the mounting plate 11 to slide along the slide rails 17 via the pulley 16, thus realizing the movement of the corner saw 4 along the Y-axis.

[0021] (2) Implementation of vertical rotation assembly The second mounting base 10 is fixedly mounted on the upper surface of the mounting plate 11. The upper end of the second mounting base 10 is fixedly connected to the shaft of the second motor 9. The second motor 9 is fixed to the bottom of the corner saw 4. When the second motor 9 is started, its shaft drives the corner saw 4 to rotate in the vertical direction, thereby adjusting the vertical angle of the corner saw 4.

[0022] (3) Implementation of X-axis moving components A third mounting base 8 is installed on the upper end of the second motor 9. A fourth motor 22 is installed on the top of the third mounting base 8. The shaft of the fourth motor 22 is connected to the second worm gear 21. The second worm gear 21 meshes with the first worm wheel 25. The first worm wheel 25 is fixed on the support rod 24. The middle part of the support rod 24 is rotatably connected to the support plate 23. The two ends of the support rod 24 are fixed with the second worm wheels 26. The second worm wheels 26 mesh with the first worm gear 7. The first worm gear 7 is screwed onto the third mounting base 8. When the fourth motor 22 is started, it drives the second worm gear 21 to rotate, which in turn drives the first worm wheel 25 and the support rod 24 to rotate. The second worm wheel 26 rotates accordingly, which drives the two first worm gears 7 to move along the X-axis, realizing the movement of the chamfer saw 4 in the X-axis direction.

[0023] (4) Implementation of horizontal rotation assembly and clamping device A mounting box 301 is embedded in the processing table 2. A fifth motor 303 and a sixth motor 304 are mounted on the bottom of the mounting box 301. A first spur gear 305 is mounted on the shaft of the fifth motor 303. The first spur gear 305 meshes with a second spur gear 306 at the lower end of the connecting rod 307. The upper end of the connecting rod 307 is connected to the clamping worktable 302. When the fifth motor 303 is started, the first spur gear 305 rotates, driving the second spur gear 306 and the connecting rod 307 to rotate, thereby causing the clamping worktable 302 to rotate horizontally.

[0024] In the clamping device 3, a third spur gear 308 is mounted on the shaft of the sixth motor 304. The third spur gear 308 meshes with a fourth spur gear 309 at the bottom of the sleeve 310. The sleeve 310 is fitted onto the outer wall of the connecting rod 307, and a first bevel gear 311 is mounted on its upper end. Two sliding grooves 313 are provided on the upper end of the clamping worktable 302. A clamping plate 312 is slidably connected within the sliding grooves 313. The bottom of the clamping plate 312 is threaded into a second lead screw 314. A second bevel gear 315 is mounted on one end of the second lead screw 314, and the second bevel gear 315 meshes with the first bevel gear 311. When the sixth motor 304 is started, the third spur gear 308 rotates, driving the fourth spur gear 309 and the sleeve 310 to rotate. The first bevel gear 311 rotates accordingly, meshing with the second bevel gear 315 and driving the second lead screw 314 to rotate. This causes the two clamping plates 312 to move along the sliding grooves 313, thus clamping or releasing the workpiece.

[0025] The two conical positioning plates 18 at the left end of the processing table 2 facilitate the cutting of the corner saw 4 and prevent damage to the equipment; the rotating groove 19 provides operating space for the horizontal rotating assembly; the support leg 20 stably supports the processing table 2.

[0026] First, the support leg 20 is fixed to the bottom of the processing table 2, and then the processing table 2 is installed on the base 1. Then, the slide rail 17 and the limit plate 15 of the Y-axis moving assembly are fixed on the base 1, and the first lead screw 13, the threaded block 14, the mounting plate 11 and the pulley 16 are installed in sequence. Finally, the third motor 12 is installed and connected to the first lead screw 13.

[0027] A second mounting base 10 and a second motor 9 are installed on the mounting plate 11. The shaft of the second motor 9 is connected to the bottom of the corner saw 4. A third mounting base 8 is installed on the upper end of the second motor 9. The fourth motor 22, the second worm 21, the first worm wheel 25, the support rod 24, the second worm wheel 26, and the first worm 7 of the X-axis moving assembly are assembled in sequence, and the corner saw 4 is connected to the first mounting base 6 and the first motor 5.

[0028] Clamping device assembly: The fixed box 301 is embedded into the processing table 2, and the fifth motor 303, the sixth motor 304, and the corresponding spur gears are installed. The connecting rod 307 connects the second spur gear 306 and the clamping worktable 302. The sleeve 310 is fitted with the connecting rod 307 and installs the fourth spur gear 309 and the first bevel gear 311. A sliding groove 313 is opened on the clamping worktable 302, and the clamping plate 312, the second lead screw 314, and the second bevel gear 315 are installed to ensure that the second bevel gear 315 meshes with the first bevel gear 311.

[0029] II. Processing Operation The workpiece is placed on the clamping worktable 302, and the sixth motor 304 is started. The third spur gear 308 and the fourth spur gear 309 drive the sleeve 310 to rotate. The first bevel gear 311 drives the second bevel gear 315 and the second lead screw 314 to rotate, so that the clamping plate 312 moves along the slide groove 313 and clamps the workpiece.

[0030] According to the cutting requirements, the third motor 12 is started to adjust the Y-axis position of the cutting saw 4 through the Y-axis moving component, the second motor 9 is started to adjust the vertical angle of the cutting saw 4 through the vertical rotation component, the fourth motor 22 is started to finely adjust the X-axis position of the cutting saw 4 through the X-axis moving component, and the fifth motor 303 is started to adjust the horizontal angle of the workpiece through the horizontal rotation component.

[0031] After the adjustment is completed, start the first motor 5 to drive the corner saw 4 to run and complete the corner cutting of the workpiece.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
