Description

Technical Field

[0001] This invention belongs to the field of rotating shaft manufacturing technology, specifically relating to a computer-controlled automatic rotating shaft production line and its operation method. Background Technology

[0002] Computer spindles are divided into types such as straight spindles and single-axis rotary spindles. The spindle core inside the spindle assembly is an important component of the entire spindle assembly. Therefore, the quality of the spindle core can affect the working quality and service life of the entire spindle assembly.

[0003] However, the existing technology does not involve the detection of surface roughness and amplitude in the manufacturing of shaft cores, thus failing to guarantee the quality of subsequent shaft cores. Summary of the Invention

[0004] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to provide an automated production line for computer-controlled rotary shafts and its operation method.

[0005] This invention provides the following technical solution:

[0006] An automated production line for computer-controlled spindles includes a grinding and cutting assembly for grinding and cutting spindle cores, a roughness detection assembly for detecting the surface roughness of spindle cores, and a vibration measurement assembly for detecting the amplitude of spindle core vibration. The grinding and cutting assembly, the roughness detection assembly, and the vibration measurement assembly transfer spindle cores between them via a robotic arm.

[0007] Specifically, the grinding and cutting assembly includes a worktable, a cam pusher movably mounted on the worktable, a rough grinding assembly, a fine grinding assembly, and a cutting assembly; the grinding and cutting assembly has three stations, namely a rough grinding station, a fine grinding station, and a cutting station, and the cam pusher is used to push the raw material for rough grinding, fine grinding, and cutting.

[0008] Specifically, the cam pusher includes a worktable, a fixed seat and a positioning frame mounted on the worktable, a main shaft movably mounted on the fixed seat and the positioning frame via a motor, a bushing mounted on the main shaft, a limit seat, a first limit seat and a second limit seat mounted on the bushing, the first limit seat and the second limit seat forming a cam track, a processing unit movably placed in the cam track and evenly distributed around the axis of the main shaft, the processing unit containing raw materials; an outer disk movably mounted on the main shaft, the outer disk having a groove around the axis of the main shaft, one end of the raw materials passing through the outer disk and placed in the groove.

The raw material is clamped onto the connecting shaft via a clamp. A cylinder three is installed inside the motor base, and a positioning hole is provided on the limit seat corresponding to the position of cylinder three. When the raw material completes one workstation operation, i.e., motor two rotates n times (n is a positive integer), cylinder three is activated, so that the cylinder rod extends into the positioning hole to fix the processing unit, thereby driving the processing unit to rotate to the next workstation.

[0010] Specifically, the coarse grinding assembly includes a shaft 1 that is movably mounted on a positioning frame via a motor 3. A coarse grinding blade is mounted on the shaft 1, and the coarse grinding blade is in contact with an external disc and positioned above a groove.

[0011] Specifically, the fine grinding assembly includes a shaft 2 that is movably mounted on a positioning frame via a motor 4. A fine grinding cutter is mounted on the shaft 2 and is in contact with an external disc and positioned above a groove.

[0012] Specifically, the cutting assembly includes a shaft three that is movably mounted on a positioning frame via a motor five and a cylinder four, and a sensor mounted on the positioning frame. A cutting blade is mounted on the shaft three and is in contact with an external disk. When the sensor senses that the raw material has extended to the designated position, the motor five and the cylinder four are turned on, and the cylinder four pushes the cutting blade to cut.

[0013] Specifically, the roughness inspection component includes a base plate, a mounting bracket movably mounted on the base plate via a height adjustment pin, the mounting bracket being movably mounted on the base plate via a positioning rod and spring in conjunction with a positioning seat, a pressure plate mounted at the bottom of the mounting bracket, the pressure plate being mounted on the base plate via an elbow clamp, a surface roughness measuring machine mounted on the mounting bracket, a support seat positioned directly below the measuring end of the surface roughness measuring machine and mounted on the base plate, and the workpiece being placed on the support seat.

[0015] Based on the above-described device, the present invention also proposes an operating method for an automated production line using a computer-controlled rotary shaft, comprising the following steps:

[0016] S1, the grinding and cutting components perform coarse grinding, fine grinding and cutting of the raw materials;

[0038] Computer spindles are divided into types such as straight spindles and single-axis rotary spindles. The spindle core inside the spindle assembly is an important component of the entire spindle assembly. Therefore, the quality of the spindle core can affect the working quality and service life of the entire spindle assembly.

[0039] like Figure 1 As shown, the present invention provides an automated production line for computer spindles, including a grinding and cutting component 1 for grinding and cutting the spindle core, a roughness detection component 2 for detecting the surface roughness of the spindle core, and a vibration measurement component 3 for detecting the amplitude of the spindle core. The grinding and cutting component 1, the roughness detection component 2 and the vibration measurement component 3 are connected by a robotic arm to transfer the spindle core.

[0040] First, the raw material undergoes rough grinding, fine grinding, and cutting into shaped shaft cores. Then, the shaft cores are transported by a robotic arm to the surface roughness detection component 2 for surface roughness testing. Finally, the robotic arm transfers the shaft cores to the vibration measurement component 3 to detect the amplitude of vibration. This completes the manufacturing, roughness testing, and amplitude testing of the shaft cores. Roughness testing ensures the quality of the shaft cores; simultaneously, since the internal environment of a computer generates slight vibrations during operation, it is necessary to detect the shaft core amplitude to further determine the quality and lifespan of the shaft cores.

[0041] Please refer to this carefully. Figure 2The grinding and cutting assembly 1 includes a worktable 101, a cam pusher 102 movably mounted on the worktable 101, a rough grinding assembly 103, a fine grinding assembly 104, and a cutting assembly 105. The grinding and cutting assembly 1 has three stations: a rough grinding station, a fine grinding station, and a cutting station. The cam pusher 102 is used to push the raw material for rough grinding, fine grinding, and cutting.

[0042] Please refer to this carefully. Figure 3 The cam pusher 102 includes a worktable 101, a fixed seat 1026 and a positioning frame 10211 mounted on the worktable 101, a main shaft 1021 movably mounted on the fixed seat 1026 and the positioning frame 10211 via a motor, a bushing 1022 mounted on the main shaft 1021, a limit seat 1023, a first limit seat 1024 and a second limit seat 1025 mounted on the bushing 1022, the first limit seat 1024 and the second limit seat 1025 forming a cam path 1028, and a processing unit 1027 movably placed in the cam path 1028 via bearings and evenly placed around the axis of the main shaft 1021, with raw materials installed in the processing unit 1027.

[0043] Therefore, when the spindle 1021 rotates, the machining unit 1027 can move back and forth with the cam path 1028.

[0044] Furthermore, the external disk 1029 is movably mounted on the main shaft 1021. The external disk 1029 has a groove 10210 around the axis of the main shaft 1021. One end of the raw material passes through the external disk 1029 and is placed in the groove 10210.

[0045] Please refer to this carefully. Figure 2 , 4 5. The processing unit 1027 includes a small motor 10271 mounted on a motor base 10274. A connecting shaft 10272 is mounted on the small motor 10271. The raw material is clamped onto the connecting shaft 10272 via a clamp 10273.

[0046] When motor 2 and small motor 10271 are turned on, the raw material will move back and forth in the groove 10210 and rotate in the groove 10210.

[0047] For further details, please refer to the following: Figure 3 The processing unit 1027 also includes a cylinder 10275 installed in the motor base 10274, and a positioning hole 10276 on the limit seat 1023 corresponding to the position of the cylinder 10275. When the raw material completes one station operation, that is, after the motor rotates n times (n is a positive integer), the cylinder 10275 is opened, so that the cylinder rod extends into the positioning hole 10276 to fix the processing unit 1027, thereby driving the processing unit 1027 to rotate to the next station.

[0048] Please refer to this carefully. Figure 3 The coarse grinding assembly 103 includes a shaft 1032 movably mounted on a positioning frame 10211 via a motor. A coarse grinding blade 1031 is mounted on the shaft 1032. The coarse grinding blade 1031 contacts the outer disk 1029 and is positioned above a groove 10210, so that when the processing unit 1027 moves back and forth and rotates, the coarse grinding blade 1031 performs coarse grinding on the raw material.

[0049] The fine grinding assembly 104 includes a shaft 1042 movably mounted on a positioning frame 10211 via a motor. A fine grinding blade 1041 is mounted on the shaft 1042. The fine grinding blade 1041 contacts the outer disk 1029 and is positioned above a groove 10210, so that the fine grinding blade 1041 performs fine grinding on the raw material when the processing unit 1027 moves back and forth and rotates.

[0050] The cutting assembly 105 includes a shaft 1052 movably mounted on a positioning frame 10211 via a motor 5 and a cylinder 4, and a sensor mounted on the positioning frame 10211. A cutting blade 1051 is mounted on the shaft 1052 and is in contact with an external disk 1029. When the sensor senses that the raw material has extended to a designated position, the motor 5 and the cylinder 4 are activated, and the cylinder 4 pushes the cutting blade 1051 to cut.

[0051] Please refer to this carefully. Figure 6 The surface roughness inspection assembly 2 includes a base plate 201, a mounting bracket 204 movably mounted on the base plate 201 via a height adjustment pin 209, and a positioning seat 208 via a positioning rod 206 and a spring 207. A pressure plate 205 is mounted on the bottom of the mounting bracket 204, and the pressure plate 205 is mounted on the base plate 201 via an elbow clamp 202. A surface roughness measuring machine 203 is mounted on the mounting bracket 204, and a support seat 210 is positioned directly below the measuring end of the surface roughness measuring machine 203 and mounted on the base plate 201. The workpiece is placed on the support seat 210. To ensure that the measuring end of the surface roughness measuring machine 203 fully contacts the workpiece, the mounting bracket 204 is mounted in conjunction with the elbow clamp 202. Furthermore, to prevent the surface roughness measuring machine 203 from pressing completely onto the workpiece and causing damage, a height adjustment pin 209 is included.

[0052] The design of the height adjustment pin 209 in conjunction with the elbow clamp 202 ensures that the measuring end of the surface roughness measuring machine 203 does not press completely on the workpiece, while also ensuring that the measuring end can fully contact the workpiece.

[0053] When the robot places the workpiece on the support 210, the elbow clamp 202 is pressed down manually so that the measuring end contacts the workpiece.

[0054] Please refer to this carefully. Figure 7 The vibration measuring component 3 includes a base plate 312, a bracket 313 movably mounted on the base plate 312 via a linear guide rail 314, a motor 301 movably mounted on the bracket 313 via a cylinder 303, a vibrating wheel 302 mounted on the motor 301, a mounting plate 315 movably mounted on the bracket 313 via a cylinder 304, a contact sensor 305 mounted on the mounting plate 315, a mounting seat 308 movably mounted on the mounting plate 315 via a guide shaft 307 and a bearing assembly 306, a roller 309 mounted on the mounting seat 308 and in contact with the contact sensor 305, a support 310 mounted on the base plate 312, and rollers 311 symmetrically mounted on the support 310.

[0055] When the robotic arm places the workpiece between rollers 311, cylinders 303 and 304 and motor 301 are activated. Then, the support 313 is moved to the point to be measured. Motor 301 drives the vibrating wheel 302 to rotate. Then, the vibrating wheel 302 contacts the workpiece, and then roller 309 contacts the workpiece. The amplitude of the workpiece is detected by the contact sensor 305. Then, the support 313 is moved to other points to be measured, which can measure the amplitude at different positions.

[0056] Motor 2, small motor 10271, cylinder 3 10275, motor 3, motor 4, motor 5, cylinder 4, sensor, surface roughness measuring machine 203, motor 1 301, cylinder 1 303, cylinder 2 304 and contact sensor 305 are communicationally coupled control panel.

[0057] The control panel contains a PLC controller, which is a programmable numerical control system. The PLC acts as the central control system, using a touchscreen to input programs and control the entire machine, achieving full automation of the transportation process. The control system connects various actuators, allowing them to move along logical trajectories. Programming controls enable these actuators to operate according to the required steps.

[0058] Based on the above-described device, the present invention also proposes an operating method for an automated production line using a computer-controlled rotary shaft, comprising the following steps:

[0059] Step 1: The grinding and cutting component 1 performs coarse grinding, fine grinding, and cutting on the raw material;

[0060] Step 2: The robot arm transports the workpiece to the surface roughness detection component 2, and the surface roughness detection component 2 performs surface roughness detection on the workpiece.

[0061] Step 3: The robot arm transports the workpiece to the vibration measuring component 3, and the vibration measuring component 3 detects the amplitude of the workpiece.

[0062] This device is designed to continuously perform coarse grinding, fine grinding, and cutting of raw materials, while also detecting the surface roughness and amplitude of workpieces.
