Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of mechanical processing, and particularly relates to a mechanical processing corner cutting device. BACKGROUND

[0002] In the field of mechanical processing, workpiece corner cutting processing often needs to simultaneously involve angle cutting of horizontal and vertical planes (such as corner processing of frame type workpieces, multi-surface chamfering of special-shaped components, etc.). However, the existing corner cutting device has significant technical limitations: the angle adjustment function is mostly limited to a single plane, and can only realize angle adjustment of the workpiece or the corner cutting saw in the horizontal plane, or can only complete inclined cutting of the corner cutting saw in the vertical plane, and cannot realize coordinated adjustment of the "horizontal-vertical" double planes. Specifically, when the workpiece needs to be processed simultaneously with horizontal and vertical corner cutting, the operator needs to complete the processing in two steps: first, fix the workpiece on the workbench to complete the corner cutting process in the horizontal plane; second, manually disassemble the processed part, re-adjust the posture of the workpiece (such as turning the original vertical plane to the horizontal plane), and then fix it again before starting the device to complete the corner cutting process in the vertical plane. This mode of "single-plane single processing, multi-plane multi-step" not only leads to a complicated processing flow and prolonged operation time, but also easily causes positioning deviation due to repeated fixation of the workpiece, and the two fixed references are difficult to be completely consistent, which easily causes size misplacement and angle deviation of the horizontal and vertical corner cutting, and finally affects the assembly accuracy of the workpiece; at the same time, manual repeated assembly and disassembly of the workpiece increases the labor intensity, and there is a risk of damage to the workpiece during turning and carrying, which further reduces the processing efficiency and product qualification rate, and is difficult to meet the production demand of modern mechanical processing for "high efficiency, precision and integration". In view of this, the present application provides a mechanical processing corner cutting device. SUMMARY

Secondly, the vertical rotating assembly comprises a second mounting seat fixedly installed on the upper surface of the mounting plate, and the upper end of the second mounting seat is fixedly connected with the rotating shaft of the second motor fixedly installed at the bottom of the angle cutting saw.

[0004] Meanwhile, the X-axis moving assembly comprises a third mounting seat installed on the upper end of the seventh motor, a fourth motor is detachably installed on the top of the third mounting seat, the rotating shaft of the fourth motor is connected with a second worm, the second worm is in meshing connection with a first worm wheel, the first worm wheel is fixedly installed on a supporting rod, the supporting rod is in rotating connection with a supporting plate fixedly installed on the top of the third mounting seat at the middle part of the supporting rod, second worm wheels are fixedly installed at both ends of the supporting rod, and the second worm wheels are in meshing connection with two first worms which are in threadedly screwed connection with the upper end of the third mounting seat.

[0005] The first mounting seat is installed at the rear end of the first worm, the upper end of the first mounting seat is provided with the first motor, and the rotating shaft of the first motor is in rotating connection with the bottom of the angle cutting saw.

[0006] Further, the horizontal rotating assembly comprises a fixed box embeddedly installed on the processing table, the bottom of the fixed box is detachably provided with a fifth motor and a sixth motor, the rotating shaft of the fifth motor is fixedly installed with a first spur gear, the first spur gear is in meshing connection with a second spur gear fixedly installed at the lower end of a connecting rod, the upper end of the connecting rod is fixedly connected with the top of a clamping workbench, and the lower surface of the clamping workbench is in contact connection with the upper surface of the fixed box.

[0007] Secondly, the clamping device comprises a third spur gear fixedly installed on the rotating shaft of the sixth motor, the third spur gear is in meshing connection with a fourth spur gear fixedly installed at the bottom of a sleeve, the sleeve is sleeved on the outer wall of the connecting rod, and the upper end of the sleeve is provided with a first bevel gear.

[0008] Secondly, the clamping device further comprises two sliding grooves which are arranged along the same straight line at the upper end of the clamping workbench, a clamping plate is in sliding connection in the sliding grooves, the bottom of the clamping plate is in threadedly screwed connection with a second screw rod, the second screw rod is fixedly installed with a second bevel gear at the center one end close to the clamping workbench, and the second bevel gear is in meshing connection with the first bevel gear.

[0009] Further, the left end of the processing table is provided with two tapered positioning plates, the tips of the two tapered positioning plates are arranged along the radial direction, and the distance between the tips is greater than the thickness of the saw blade of the angle cutting saw, so as to facilitate the falling of the saw blade of the angle cutting saw and prevent the equipment from being damaged.

The two can be synchronized or continuously completed to realize the horizontal and vertical plane corner cutting of the workpiece, completely eliminating the cumbersome steps of "disassembling - turning over - re-fixing", simplifying the multi-step processing into single clamping completion, and greatly shortening the processing cycle. 2. Eliminate repeated positioning deviation and improve processing precision: since the workpiece only needs to be clamped once to complete the two-plane corner cutting, the reference misplacement problem caused by multiple fixings is avoided. The clamping device realizes stable clamping through gear-screw rod transmission, ensuring that the workpiece always maintains positioning accuracy during horizontal rotation and vertical corner cutting; at the same time, the X-axis and Y-axis moving assemblies realize millimeter-level adjustment through screw-worm transmission, further guaranteeing the relative position accuracy of the corner saw and the workpiece, so that the size and angle deviation of the horizontal corner cutting and the vertical corner cutting are controlled in a very small range, significantly improving the workpiece assembly adaptability.
