Description

Technical Field

[0001] This invention belongs to the field of CNC machine tool technology, specifically a turning and milling composite machine tool. Background Technology

[0002] CNC machine tools are short for numerical control machine tools. They are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, input them to the CNC device through an information carrier, and after calculation and processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and size required by the drawings.

[0003] A multi-axis vertical turning-milling composite CNC machine tool with publication number CN120326372B is available. It can perform milling, grinding, and turning operations on workpieces. Different processes can be completed on a single CNC machine tool without the need to transfer the workpiece, saving workpiece transfer time and improving workpiece processing efficiency. However, in this type of rotatable and adjustable machining table, the grinding wheel and cutting end will continuously exert a strong vibration force on the workpiece during the process of using a three-jaw chuck to hold the workpiece. This causes the first rotating connecting plate to easily deflect slightly around the second rotating connecting plate along the rotating connecting piece, resulting in instability in the three-jaw chuck's workpiece clamping. Therefore, improvements are needed. Summary of the Invention

[0004] To address the problem of workpiece wobbling during machining using existing grinding wheels, the present invention provides a milling-turning machine tool comprising a control component, a grinding component, and a suspension component. The control component is located at the back of the suspension component, and the grinding component is located at the front of the control component. The suspension component includes a container base, a propulsion component, a gripper disc, and a suction unit. The gripper disc is a three-jaw chuck used to hold the workpiece being processed. The middle part of the inner cavity of the container base is inserted into the outer surface of the adsorber through a slot. A discharge pipe is inserted into the front part of the adsorber, and the front end of the discharge pipe extends to the outside of the container base. The adsorber adsorbs the processing debris into the box through the upper mesh groove, and discharges the waste through the front discharge pipe. The propulsion components are symmetrically arranged on the left and right sides of the inner cavity of the container base, and the outer surface of the propulsion components is inserted into the bottom of the gripper disk. The propulsion component includes a guide ring shell, an inner sliding arc plate, a deflection base, a connecting guide plate, and a pressure plate; The lower surface of the pressure plate is inserted into the upper surface of the connecting guide plate, the right end of the guide ring shell is inserted into the lower surface of the connecting guide plate, the right side of the outer surface of the deflection base is rotatably connected to the left side of the outer surface of the connecting guide plate, a guide groove is provided in the upper part of the inner cavity of the deflection base, and the bottom of the gripper plate is inserted into the upper surface of the connecting guide plate through the guide groove. The bottom of the gripper plate can slide along the guide groove and then be inserted into the deep part of the guide groove for fixation. The outer surface of the inner sliding arc plate is slidably connected to the inner wall of the guide ring shell. The end of the inner sliding arc plate away from the connecting guide plate is inserted into the lower surface of the deflection base. After the pressure plate applies pressure to the right side of the inner cavity of the guide ring shell, the inner sliding arc plate will deflect clockwise along the inner cavity of the guide ring shell under the pressure, pushing the deflection base on the left side clockwise. The deflection base drives the upper gripper plate to rotate from a horizontal state to a vertical state. Then the deflection base is blocked by the connecting guide plate and cannot deflect.

[0005] Furthermore, the propulsion component also includes: A filler spring is provided outside the inner sliding arc plate. One end of the filler spring is inserted into the end of the inner sliding arc plate near the connecting guide plate, and the other end of the filler spring is inserted into the inner wall of the guide ring shell. A fixed base is disposed outside the guide ring housing.

[0006] Furthermore, the fixed base includes: The counterweight support shell has its inner wall fitted into the middle of the outer surface of the guide ring shell. Pressure-sensitive plates are symmetrically arranged on the front and rear sides of the inner wall of the counterweight support shell. The outer surface of the pressure-sensitive plates is inserted into the outer surface of the guide ring shell via an insertion interface. The end of the pressure-sensitive plate away from the counterweight support shell extends into the interior of the guide ring shell. After the pressure plate applies pressure to the interior of the guide ring shell, it will, on the one hand, push the inner sliding arc plate to slide and rotate clockwise, and on the other hand, it will apply pressure to the pressure-sensitive plates of the counterweight support shell. Based on the pressure applied to the pressure-sensitive plates, the pressure inside the counterweight support shell is determined, and the pressure control effect is achieved in conjunction with the pressure application of the pressure plate. A fixed base plate is provided, the bottom of which is inserted into the inner cavity of the container base.

[0007] Furthermore, the polishing component includes: A container, wherein the container is positioned in front of the control unit; The outer cylindrical grinding parts are symmetrically arranged inside the container to grind the components held by the gripper disc.

[0008] Furthermore, the control component includes: A control back panel, the bottom of which is inserted with a connecting plate, the front end of which is inserted into the back of the outer surface of the container base; The control panel is located on the front of the control back panel; Vertical guide rails are symmetrically arranged on the left and right sides of the front of the control back panel; The counterweight slide bar has its back side slidably connected to the inner wall of the vertical guide rail, and its rear end is slidably connected to the inner cavity of the control back plate via a traction device. The counterweight slide bar has a propulsion function and can drive the container to move back and forth through the slidable rod at the axis. After the parameters are set by the operation panel, the control back plate can drive the counterweight slide bars on both sides to move in a directional manner along the vertical guide rail by activating the internal traction device.

[0009] Furthermore, the control component also includes: A transverse guide rail, the two ends of which are respectively inserted into the front ends of the counterweight slide rods on both sides; The connecting slide is connected to the back of the outer surface of the container via a plug on its front side. The back of the inner wall of the connecting slide is slidably connected to the outer surface of the transverse guide rail via rollers. The connecting slide is equipped with motor-driven rollers inside, which can actively slide along the transverse guide rail.

[0010] Furthermore, the outer cylindrical grinding part includes: An independent motor, wherein a rotating base is inserted into the bottom end of the independent motor shaft; Adjustable pull plates are symmetrically inserted into the left and right sides of the lower surface of the rotating base; The control base shell has its outer surface inserted into the bottom end of the adjustment pull plate, and its inner cavity is rotatably connected to a grinding roller via a rotating motor.

[0011] Furthermore, the container includes: An aluminum frame housing, the back of which is plugged into the front of a connecting slide plate via a plug; The inner guide plate is symmetrically inserted into both sides of the inner wall of the aluminum frame housing, and the end of the inner guide plate away from the inner wall of the aluminum frame housing is slidably connected to the outer surface of the independent motor housing. A pressure controller is inserted into the middle of the upper surface of the aluminum frame housing, and a compression sleeve is inserted into the bottom end of the pressure controller. A buffer connector, the upper surface of which is inserted into the bottom end of the compression sleeve, and the bottom of which is inserted into the shaft center of the upper surface of the independent motor.

[0012] Furthermore, the container also includes: The inner sliding frame has its lower inner wall rotatably connected to the outer surface of the rotating base via a rotating groove, and its outer surface is slidably connected to the inner wall of the aluminum frame shell. A spring sleeve, the inner wall of which is fitted onto the upper part of the outer surface of the inner slide frame, and the bottom end of which is inserted into the lower part of the inner wall of the inner slide frame. After the pressure controller pressurizes the compression sleeve, the compression sleeve extends and pushes the outer cylindrical grinding part and the inner slide frame downward.

[0013] The beneficial effects of this invention are as follows: 1. This device can grind workpieces mounted on suspension components. Since the deflection base has both horizontal and vertical states, the gripper disc placed on top of it will also cause the workpiece to deflect, thus ensuring that the grinding components can also grind the side parts of the workpiece. After the deflection base rotates to the vertical state, a larger workpiece can be gripped and ground by the gripper discs on both sides. When the deflection base is in the vertical state, the other end of the inner sliding arc plate is subjected to pressure and continuously applies force to the deflection base, thereby counteracting the vibration generated by the workpiece during grinding. This avoids the problem of the deflection base rotating slightly around the connecting guide plate, which would lead to a decrease in workpiece stability.

[0014] 2. When the pressure inside the guide ring shell increases, it will apply pressure to the pressure-sensing plate on the inner wall of the counterweight support shell. The pressure state inside the guide ring shell can be judged based on the pressure on the pressure-sensing plate. When the pressure on the pressure-sensing plate is constant, it means that the deflection base is in a vertical state. At this time, the pressurization work of the pressure plate should be stopped in time to prevent the pressure plate from continuously pressurizing, which may cause the pressure inside the guide ring shell to become too high, exceed its threshold, and cause it to burst.

[0015] 3. When the high-speed rotating grinding roller grinds the workpiece below, the pressure controller pressurizes the inside of the compression sleeve, pushing the entire outer cylindrical grinding part along with the inner sliding frame downwards. The grinding roller is in close contact with the workpiece below, ensuring that the grinding roller will not separate from the workpiece due to the vibration generated during grinding when it contacts uneven parts of the workpiece's outer surface. At the same time, it performs high-intensity targeted grinding on harder protruding parts of the workpiece, thereby quickly eliminating grinding points and improving work efficiency.

[0016] 4. After the grinding roller finishes its work, a large amount of debris will adhere to its outer surface and the gap between it and the control base. It is difficult to clean it directly. At this time, the pressure controller periodically pressurizes the compression sleeve, and the spring sleeve drives the outer cylindrical grinding part to vibrate in the vertical direction, shaking off the debris attached to the outer surface of the grinding roller. With the guidance of the suction device directly below, the attached debris is quickly removed, avoiding the problem of too much debris accumulating on the outer surface of the grinding roller, which would affect its high-speed rotation.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: a milling and turning machine tool, comprising a control component 1, a grinding component 2, and a suspension component 3, wherein the control component 1 is disposed on the back of the suspension component 3, and the grinding component 2 is disposed on the front of the control component 1. The suspension component 3 includes a container base 31, a propulsion component 6, a gripper disc 4, and a suction unit 32. The gripper disc 4 is a three-jaw chuck used to hold the workpiece being processed. The middle part of the inner cavity of the container base 31 is inserted into the outer surface of the adsorber 32 through a slot. The front part of the adsorber 32 is connected to the discharge pipe 33, and the front end of the discharge pipe 33 extends to the outside of the container base 31. The adsorber 32 adsorbs the processing debris into the box through the upper mesh groove, and discharges the waste through the front discharge pipe 33. The propulsion components 6 are symmetrically arranged on the left and right sides of the inner cavity of the container base 31, and the outer surface of the propulsion components 6 is inserted into the bottom of the gripper disk 4. The propulsion component 6 includes a guide ring shell 62, an inner sliding arc plate 63, a deflection base 67, a connecting guide plate 65, and a pressure plate 66; The lower surface of the pressure plate 66 is inserted into the upper surface of the connecting guide plate 65, the right end of the guide ring shell 62 is inserted into the lower surface of the connecting guide plate 65, the right side of the outer surface of the deflection base 67 is rotatably connected to the left side of the outer surface of the connecting guide plate 65, a guide groove 68 is provided in the upper part of the inner cavity of the deflection base 67, and the bottom of the gripper plate 4 is inserted into the upper surface of the connecting guide plate 65 through the guide groove 68. The bottom of the gripper plate 4 can slide along the guide groove 68 and then be inserted into the deep part of the guide groove 68 for fixing. The outer surface of the inner sliding arc plate 63 is slidably connected to the inner wall of the guide ring shell 62. The end of the inner sliding arc plate 63 away from the connecting guide plate 65 is inserted into the lower surface of the deflection base 67. After the pressure plate 66 applies pressure to the right side of the inner cavity of the guide ring shell 62, the inner sliding arc plate 63 will deflect clockwise along the inner cavity of the guide ring shell 62 under the action of pressure, pushing the deflection base 67 on the left side clockwise. The deflection base 67 drives the upper gripper disk 4 to rotate from a horizontal state to a vertical state. Then the deflection base 67 is blocked by the connecting guide plate 65 and cannot deflect.

[0021] Propulsion component 6 also includes: A filler spring 64 is disposed outside the inner sliding arc plate 63. One end of the filler spring 64 is inserted into the end of the inner sliding arc plate 63 near the connecting guide plate 65, and the other end of the filler spring 64 is inserted into the inner wall of the guide ring shell 62. A fixed base 61 is disposed outside the guide ring housing 62.

[0022] The fixed base 61 includes: The counterweight support shell 612 has its inner wall sleeved with the middle of the outer surface of the guide ring shell 62. Pressure-sensing plates 613 are symmetrically arranged on the front and rear sides of the inner wall of the counterweight support shell 612. The outer surface of the pressure-sensing plate 613 is inserted into the outer surface of the guide ring shell 62 through the insertion interface. The end of the pressure-sensing plate 613 away from the counterweight support shell 612 extends into the interior of the guide ring shell 62. After the pressure plate 66 applies pressure to the interior of the guide ring shell 62, it will push the inner sliding arc plate 63 to slide and rotate clockwise on the one hand, and apply pressure to the pressure-sensing plate 613 of the counterweight support shell 612 on the other hand. The pressure inside the counterweight support shell 612 is judged according to the pressure of the pressure-sensing plate 613, and the pressure control effect is achieved in conjunction with the pressure application of the pressure plate 66. The base plate 611 is fixed, and the bottom of the base plate 611 is inserted into the inner cavity of the container base 31.

[0023] After the workpiece is clamped on the jaw plate 4, the preparation work is completed, and the clamped workpiece is ground by the upper grinding component 2.

[0024] The control unit 1 drives the grinding unit 2 to approach the lower workpiece. The debris that falls off the workpiece during grinding is promptly carried away by the suction device 32 in the middle to achieve the cleaning work. During the actual processing, the pressure plate 66 located on the side of the deflection base 67 will push the inner sliding arc plate 63 inside the guide ring shell 62 to slide by pressurizing the connecting guide plate 65, thereby turning the horizontal deflection base 67 into a vertical state. Then, by maintaining the internal pressure of the guide ring shell 62, the clamped workpiece can be clamped into a vertical state.

[0025] When the pressure inside the guide ring shell 62 increases, it will apply pressure to the pressure-sensitive plate 613 on the inner wall of the counterweight support shell 612. The pressure state inside the guide ring shell 62 can be judged based on the pressure on the pressure-sensitive plate 613. When the pressure on the pressure-sensitive plate 613 is constant, it means that the deflection base 67 is in a vertical state. At this time, the pressurization work of the pressure plate 66 should be stopped in time.

[0026] Example 2, please refer to Figures 1-9 The present invention provides a technical solution: based on embodiment 1, the grinding component 2 includes: Container 21 is located at the front of control unit 1; The outer cylindrical grinding parts 22 are symmetrically arranged inside the container 21 to grind the components held by the gripper disc 4.

[0027] Control component 1 includes: A control back panel 11 is provided, and a connecting plate 12 is inserted into the bottom of the control back panel 11. The front end of the connecting plate 12 is inserted into the back of the outer surface of the container base 31.

The counterweight slide bar 14 has a propulsion function and can drive the container 21 to move back and forth through the slidable rod at the axis. After the parameters are set by the operation panel 15, the control back plate 11 can drive the counterweight slide bars 14 on both sides to move in a directional manner along the vertical guide rail 13 by activating the internal traction device.

[0028] Control unit 1 also includes: The transverse guide rail 16 has two ends that are respectively inserted into the front ends of the counterweight slide rods 14 on both sides. The connecting slide 17 is connected to the back of the outer surface of the container 21 via a plug on the front. The back of the inner wall of the connecting slide 17 is slidably connected to the outer surface of the transverse guide rail 16 via rollers. The connecting slide 17 is equipped with motor-driven rollers inside, which can actively slide along the transverse guide rail 16.

[0029] The external cylindrical grinding part 22 includes: Independent motor 221, with a rotating base 222 inserted into the bottom end of the shaft of independent motor 221; Adjusting pull plates 223 are symmetrically inserted into the left and right sides of the lower surface of the rotating base 222; The control base 224 is inserted into the bottom end of the adjustment plate 223 on its outer surface. The inner cavity of the control base 224 is connected to the grinding roller 225 by a rotating motor.

[0030] Container 21 includes: The aluminum frame housing 211 has a back that is plugged into the front of the connecting slide plate 17 via a plug; The inner guide plate 215 is symmetrically inserted into both sides of the inner wall of the aluminum frame housing 211. The end of the inner guide plate 215 away from the inner wall of the aluminum frame housing 211 is slidably connected to the outer surface of the housing of the independent motor 221. Pressure controller 212 is inserted into the middle of the upper surface of aluminum frame housing 211, and a compression sleeve 213 is inserted into the bottom end of pressure controller 212. The upper surface of the buffer connector 214 is inserted into the bottom end of the compression sleeve 213, and the bottom of the buffer connector 214 is inserted into the shaft center of the upper surface of the independent motor 221.

[0031] Container 21 also includes: The inner sliding frame 216 has its lower inner wall rotatably connected to the outer surface of the rotating base 222 via a rotating groove, and its outer surface is slidably connected to the inner wall of the aluminum frame shell 211.

After pressure controller 212 pressurizes compression sleeve 213, compression sleeve 213 extends and pushes outer cylindrical grinding part 22 and inner slide frame 216 downward.

[0032] During the processing, the control back plate 11 pulls the grinding component 2 vertically along the vertical guide rail 13 to move it downwards closer to the workpiece below. The counterweight slide bar 14 pushes the grinding component 2 forward. Then, the grinding component 2 slides left and right along the horizontal guide rail 16 through the connecting slide plate 17 on the back, thereby ensuring the freedom of the grinding component 2.

[0033] The control base 224 drives the grinding roller 225 to rotate at high speed through the motor in the inner cavity. During the grinding process, the independent motor 221 can drive the grinding roller 225 to deflect its axis by twisting the rotating base 222, thereby changing the working part of the grinding roller 225.

[0034] The pressure controller 212 pressurizes the inside of the compression sleeve 213, pushing the entire outer cylindrical grinding part 22 and the inner sliding frame 216 downward. At this time, the spring sleeve 217 is compressed, and the grinding roller 225 fits more tightly with the workpiece below, thus ensuring that the grinding roller 225 will not separate from the workpiece due to the vibration generated by grinding when it contacts the uneven parts of the outer surface of the workpiece. After the grinding is completed, the pressure controller 212 shuts off instantly. The compressed spring sleeve 217 drives the inner sliding frame 216 to push upward, resetting the outer cylindrical grinding part 22. Then, the spring sleeve 217 drives the inner sliding frame 216 and the outer cylindrical grinding part 22 to vibrate in the vertical direction, shaking off the debris attached to the outer surface of the grinding roller 225.
