Description

Technical Field

[0001] The invention relates to the technical field of engineering machinery, and in particular to a milling, grinding and deburring integrated numerical control device. Background Art

[0002] Milling is the process of removing material from a workpiece using a rotating tool by advancing the tool into the workpiece in a certain direction. Milling usually uses a milling machine, which has cutting blades that rotate as they are pressed against the workpiece. The workpiece is fixed in place so that it does not rotate or otherwise move. Milling can be divided into face milling and peripheral milling, depending on the position of the cutting tool. After some tubular workpieces are milled, they are face ground to remove burrs from their surface and improve the surface roughness of the tubular workpiece.

[0003] At present, some CNC equipment can only perform separate milling processing. When the workpiece needs to be surface-grinded, it is necessary to manually disassemble the workpiece and transfer it to a special grinding device for installation. In this way, the grinding process needs to be added during processing, and an additional grinding device is required. This means that when mass-producing parts, an additional grinding process is required, and the operator needs to frequently manually disassemble the workpiece and transfer it to another device, which takes more processing time and reduces the processing efficiency.

[0065] Moreover, the adjustment plate 10 includes a limit plate 101, and a rounded corner portion 1011 is provided at the end of the limit plate 101 facing the milling processing module 01. The upper surface of the limit plate 101 is vertically connected to a limit side plate 102, and a guide plate 103 is fixedly connected to one side of the limit side plate 102. The limit side plate 102 is used to resist the clamping claw mechanism 7.

[0066] In this embodiment, when the tubular workpiece body 06 is milled and polished to remove burrs, the present CNC equipment can be selected. The present CNC equipment is a CNC equipment integrating milling and polishing. First, the workpiece body 06 is installed on the pneumatic clamping mechanism 04 and clamped by the pneumatic clamping mechanism 04. Then, the spindle mechanism 013 cooperates with the transverse moving mechanism 011 and the longitudinal moving mechanism 012 to move to mill the workpiece body 06. After completing the milling process on the CNC equipment, the spindle mechanism 013 cooperates with the transverse moving mechanism 011 to retreat to one side, and then the workpiece body 06 is transferred to the side of the polishing module 02 through the workpiece transfer module 03 for polishing and deburring.

[0067] First, the clamping arm mechanism 6 clamps and picks up the workpiece body 06. First, the lifting mechanism 3 raises the height of the clamping arm mechanism 6, and the piston rod of the servo electric cylinder 31 extends or contracts, so that the motor mounting plate 34 is height adjusted, so that the clamping claw mechanisms 7 on both sides can be raised or lowered to a specified height, and the workpiece body 06 is located between the claws 71 on both sides. At this time, the screw motor 35 drives the threaded rod 43 to rotate, and cooperates with the sliding rods 42 on both sides to slide on the sliding rod limit frame 36, so that the synchronization mechanism 4 can only move vertically up and down.

[0068] When the synchronous plate 41 moves up and down, the single-rod bearing 621 at the limiting slide groove 411 will change position synchronously with the position change of the synchronous plate 41, because the second slider 63 moves longitudinally in the slide groove at the bottom of the third slide rail 52. As a result, when the synchronous plate 41 moves up and down, the single-rod bearing 621 slides in the limiting slide groove 411, thereby driving the second sliders 63 on both sides to approach or move away at the same time, so that the clamping arms 61 on both sides are close to each other, so that the claws 71 can clamp the workpiece body 06.

[0069] After the clamping claw 71 clamps the workpiece body 06, the lifting mechanism 3 rises. At this time, the sliding seat 22 slides on the first slide rail 21, so that the clamping arm mechanism 6 drives the workpiece body 06 to move to the grinding module 02 on one side. At this time, the vertical state of the workpiece body 06 needs to be changed to a horizontal state.

[0070] During this process, when the clamping arm mechanism 6 moves to the clamping claw angle adjustment unit 05, the angle will be automatically adjusted. First, the connecting plates 73 on both sides will be released from the guide plate 103. The guide plate 103 is used to ensure that the connecting plate 73 will open the adjustment plate 10 as a whole. Because when clamping tubular workpiece bodies 06 of different diameters, the distance between the claws 71 will also be different, so after the connecting plate 73 contacts the guide plate 103, the adjustment plates 10 on both sides will be slowly opened, causing the second telescopic rod 91 to contract, thereby adjusting the spacing between the adjustment plates 10 on both sides, and under the action of the second spring 92, the adjustment plates 10 on both sides are always against the connecting plates 73 on both sides.

[0071] Once the connecting plate 73 moves to the limit abutment 101, the rounded corner 1011 of the limit abutment 101 abuts against the lower half of the connecting plate 73. As the clamping arm mechanism 6 moves laterally, the connecting plate 73 will rotate around the axis of the bearing 613 due to the abutment of the limit abutment 101, thereby changing from a vertical state to a parallel state with the limit abutment 101, causing the clamping claw mechanism 7 to rotate 90°, thereby driving the workpiece body 06 to rotate 90°, changing the original vertical state to a horizontal state. In this way, it can be ensured that after the workpiece body 06 becomes horizontal, its annular surface can contact the grinding head 022, and the grinding motor 021 drives the grinding head 022 to rotate, thereby performing surface grinding on the workpiece body 06.

[0072] And during the rotation of the connecting plate 73, the protrusion 74 rotates from the bottom to the middle, thereby causing the card plate 65 placed on top to rotate. As the position of the protrusion 74 changes, the card plate 65 rotates around the rotating rod 615, and in this process, the first telescopic rod 642 cooperates with the first spring 645, so that the top block 644 is always pressed on the card plate 65, thereby limiting the rotation angle of the connecting plate 73.

[0073] After grinding, the clamping arm mechanism 6 is disengaged from the clamping claw angle adjustment unit 05. After disengagement, the connecting plate 73 is not restricted by the limiting plate 101. At this time, the top block 644 presses on the clamping plate 65 for reset, and the first spring 645 releases elastic potential energy, so that the first telescopic rod 642 extends and resets, so that the clamping plate 65 presses the protrusion 74 downward, so that the connecting plate 73 rotates for reset, and the limiting protrusion 614 on the top can resist the connecting plate 73 to ensure that the connecting plate 73 is in a vertical state, thereby changing the clamping claw 71 and the workpiece body 06 to the original vertical state. At this time, the clamping arm mechanisms 6 on both sides are separated by driving the screw motor 35, so that the workpiece body 06 after milling and grinding can be disassembled.

[0074] Moreover, during grinding, the milling processing module 01 on the other side can perform the next round of milling processing. During the entire milling and grinding process, the staff only needs to load and unload the materials once.

[0075] In the present invention, by integrating the milling processing module 01 and the grinding module 02 into one device, after the milling processing module 01 processes the workpiece body 06, the synchronous mechanism 4 drives the clamping arm mechanism 6 to cooperate with the clamping claw mechanism 7 to install the workpiece body 06, and the adjustment plate 10 is set so that when the clamping arm mechanism 6 moves, the clamping claw mechanism 7 on the clamping arm mechanism 6 can be adjusted in angle, thereby converting it into a state where it can be ground, and the clamping plate ejection mechanism 64 cooperates with the clamping plate 65 to restore the clamping arm mechanism 6 to its initial state. In this way, the CNC equipment integrating milling and grinding can grind the tubular workpiece body 06 after milling, and the workpiece transfer module 03 can automatically transfer the workpiece body 06, so that the staff does not need to disassemble and install it on the grinding equipment after milling the workpiece body 06, which effectively saves processing time and improves processing efficiency.

[0076] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
