Description

Technical Field

[0001] This utility model relates to the technical field of milling devices, and in particular to a milling device for the end face of a tower connector. Background Technology

[0002] To ensure the reliability of the connection between the end face of the tower connector and the connecting part, the end face of the connector needs to be milled to improve its flatness. Chinese utility model patent CN206883253U discloses a milling device for connecting plates. This milling device includes a machine body and a working platform. A feeding conveyor belt is provided on one side of the working platform, and a discharging conveyor belt is provided on the other side. The working platform has a first groove station and a second groove station for positioning the connecting plate. The recess depth of both the first and second groove stations is one-third to one-half of the thickness of the milled connecting plate. Each of the first and second groove stations has several suction nozzles for adsorbing and fixing the connecting plate, and the suction nozzles are connected to suction tubes. A milling mechanism is provided above the first groove station, including a milling cutter, a milling machine table, and a milling motor. The milling machine table is slidably mounted on the machine body. A cleaning mechanism is provided above the second groove station, including a cleaning brush, a cleaning machine table, and a cleaning motor. The cleaning machine table is slidably mounted on the machine body.

[0003] The above-mentioned milling processing device uses a conveyor belt to transport the connector and a groove station to position and clamp the connector. However, the above-mentioned milling processing device cannot adjust the height of the connector. Since the height of the connector is not consistent after the initial welding processing, the connector needs to be repeatedly adjusted to the relative position with the end face of the connector when it is positioned for milling. That is, repeated centering operations are required, which leads to complicated operation and low work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a milling device for the end face of tower connectors that automatically positions and centers the end face height of the connector, is simple to operate, and has high working efficiency.

[0005] This utility model discloses a milling device for the end face of a tower connector, comprising a milling machine body and a spindle. The spindle is mounted on the milling machine body in a height-adjustable manner, and a milling cutter is mounted on the output shaft of the spindle. It also includes a robotic arm mechanism, a robotic hand mechanism, a drive motor, an active roller, a driven roller, and a photoelectric sensor. The robotic arm mechanism is mounted on the milling machine body, and the robotic hand mechanism is mounted at its end. The driven roller is rotatably mounted on the robotic hand mechanism. The drive motor is mounted on the robotic hand mechanism, and the active roller is concentrically mounted on the output shaft of the drive motor. The active roller and the driven roller cooperate to roll and clamp the connector, ensuring that the end face of the connector is perpendicular to the output shaft of the spindle. The photoelectric sensor is mounted on the milling machine body, located below the milling cutter on the spindle, and is used to position the end face of the connector. During operation, the emitting part of the photoelectric sensor emits a horizontal laser beam, targeting the middle of the connector. The connector is held between the driven and driven rollers. The robotic arm mechanism moves the connector's end face to below the spindle, aligning it with the milling cutter. The drive motor rotates the driven roller, causing friction between it and the connector, thus pushing it upwards. When the connector's end face contacts the laser beam emitted by the photoelectric sensor, the beam is reflected. The photoelectric sensor receives the reflected beam, generating an electrical signal. The drive motor stops upon receiving the signal, automatically positioning the connector's end face height for automatic alignment. The spindle then drives the milling cutter to rotate and descend according to the program. The robotic arm mechanism moves the connector horizontally via the manipulator, allowing the milling cutter to perform full milling on the connector's end face. This avoids repetitive alignment operations, simplifying operation and increasing efficiency.

[0006] Preferably, the robotic arm mechanism includes a mounting plate, a slider, and a push cylinder. The mounting plate is mounted on the end of the robotic arm mechanism, the drive motor is mounted on the mounting plate, the active roller is mounted on the output shaft of the drive motor, the slider is slidably mounted on the mounting plate, the driven roller is rotatably mounted on the slider, and the fixed end of the push cylinder is mounted on the mounting plate. The piston rod of the push cylinder is connected to the slider. The extension and retraction of the piston rod of the push cylinder drives the slider to move along the mounting plate, causing the slider to move the driven roller closer to the active roller to clamp the connector. At this time, the drive motor drives the active roller to rotate, causing the active roller to rub against the connector and rise or fall, or the slider drives the driven roller away from the active roller to release the connector, thereby realizing the rolling clamping and release of the connector.

[0007] Preferably, the driven roller includes a sleeve, a first limiting circular plate, an insert, and a second limiting circular plate. The sleeve is rotatably mounted on the slider. The first limiting circular plate is installed at the end of the sleeve near the slider. The insert is threaded into the sleeve. The second limiting circular plate is installed at the end of the insert away from the slider. The driving roller has the same structure as the driven roller. The outer wall of the sleeve rolls in contact with the connecting piece. The first and second limiting circular plates limit the outer side of the connecting piece. The insert rotates relative to the sleeve, causing the insert and sleeve to expand and contract relative to each other under the action of the threads, thereby adjusting the distance between the first and second limiting circular plates. This design is suitable for connecting pieces of different diameters and widths, and has good versatility.

[0008] Preferably, the robotic arm mechanism includes a sliding sleeve, a first horizontal arm, and a second horizontal arm. The sliding sleeve is mounted on the milling machine body. The first horizontal arm is horizontally slidable back and forth within the sliding sleeve. The second horizontal arm is rotatable and movable, horizontally mounted on the end of the first horizontal arm. The robotic arm mechanism is mounted on the end of the second horizontal arm. The first horizontal arm moves horizontally back and forth along the sliding sleeve, and the second horizontal arm moves horizontally left and right on the first horizontal arm. This allows the robotic arm mechanism to move the connecting piece horizontally, enabling the milling cutter of the spindle to perform full milling on the end face of the connecting piece. The second horizontal arm rotates on the end of the first horizontal arm, rotating the connecting piece under the spindle for milling or rotating the connecting piece out of the spindle, facilitating loading and unloading.

[0009] Preferably, it also includes a stepper motor, a lead screw, and a lead screw nut. The stepper motor is mounted on the sliding sleeve, and the lead screw is rotatably mounted on the sliding sleeve. The output shaft of the stepper motor is connected to the lead screw. The lead screw nut is mounted on the cross arm and is threadedly connected to the lead screw. The stepper motor drives the lead screw to rotate, and the lead screw and lead screw nut are threadedly connected, thereby driving the cross arm to move horizontally back and forth along the sliding sleeve, realizing the back and forth movement of the connecting part.

[0010] Preferably, the assembly also includes a first flip motor, a second sliding sleeve, a second stepper motor, a second lead screw, and a second lead screw nut. The first flip motor is installed at the end of the first horizontal arm, and the output shaft of the first flip motor is installed in the second sliding sleeve. The second horizontal arm is slidably installed in the second sliding sleeve. The second stepper motor is installed on the second horizontal arm, and the second lead screw is rotatably installed on the second horizontal arm. The output shaft of the second stepper motor is connected to the second lead screw via a transmission connection. The second lead screw nut is installed on the second sliding sleeve, and the second lead screw and the second lead screw nut are connected via a threaded transmission connection. The first flip motor drives the second sliding sleeve to rotate, and the second sliding sleeve drives the second horizontal arm to rotate, thereby driving the connecting part to rotate below or move out of the main shaft through the robotic arm mechanism, facilitating loading and unloading. The second stepper motor drives the second lead screw to rotate, and the second lead screw and the second lead screw nut are connected via a threaded transmission, thereby driving the second lead screw to move the second horizontal arm horizontally along the second sliding sleeve, adjusting the left and right positions of the connecting part, which is highly practical.

[0011] Preferably, it also includes a second flip motor, which is mounted on the end of the second horizontal arm, and the robotic arm mechanism is mounted on the output shaft of the second flip motor. The output shaft of the second flip motor drives the robotic arm mechanism to rotate, thereby milling the end faces of both ends of the connector in sequence, thereby improving processing efficiency.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, the emitting part of the photoelectric sensor emits a horizontal laser beam. The middle part of the connector is rolled and clamped between the driven roller and the driving roller. The movement of the robotic arm mechanism causes the robotic arm mechanism to move the end face of the connector to below the spindle, and make the end face of the connector concentric with the milling cutter of the spindle. The drive motor drives the driving roller to rotate, so that the driving roller rubs against the connector, thereby driving the connector upward. When the end face of the connector contacts the laser beam emitted by the photoelectric sensor, the laser beam is reflected. The receiving part of the photoelectric sensor receives the reflected laser beam, causing the photoelectric sensor to generate an electrical signal. The drive motor stops after receiving the electrical signal, thereby automatically positioning the height of the end face of the connector and completing automatic centering. At this time, the spindle drives the milling cutter to rotate and descend according to the program. The movement of the robotic arm mechanism drives the connector to move in the horizontal plane through the robotic arm mechanism, so that the milling cutter performs full milling processing on the end face of the connector, avoiding repeated centering operations, simplifying operation and increasing work efficiency.

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0021] like Figures 1 to 6 As shown, a milling device for the end face of a tower connector includes a milling machine body 1 and a spindle 2. The spindle 2 is mounted on the milling machine body 1 in a height-adjustable manner, and a milling cutter is mounted on the output shaft of the spindle 2. It also includes a robotic arm mechanism 3, a robotic hand mechanism 4, a drive motor 5, a driving roller 6, a driven roller 10, and a photoelectric sensor 7. The robotic arm mechanism 3 is mounted on the milling machine body 1, and the robotic hand mechanism 4 is mounted at the end of the robotic arm mechanism 3. The driven roller 10 is movably and rotatably mounted on the robotic hand mechanism 4. The drive motor 5 is mounted on the robotic hand mechanism 4, and the driving roller 6 is concentrically mounted on the output shaft of the drive motor 5. The driving roller 6 and the driven roller 10 cooperate to roll and clamp the connector, and the end of the connector is arranged perpendicular to the output shaft of the spindle 2. The photoelectric sensor 7 is mounted on the milling machine body 1, and the photoelectric sensor 7 is located below the milling cutter of the spindle 2. Sensor 7 is used to position the end face of the connector; the robotic arm mechanism 4 includes a mounting plate 8, a slider 9, and a push cylinder 11. The mounting plate 8 is mounted on the end of the robotic arm mechanism 3. The drive motor 5 is mounted on the mounting plate 8. The active roller 6 is mounted on the output shaft of the drive motor 5. The slider 9 is slidably mounted on the mounting plate 8. The driven roller 10 is rotatably mounted on the slider 9. The fixed end of the push cylinder 11 is mounted on the mounting plate 8. The piston rod of the push cylinder 11 is connected to the slider 9. The driven roller 10 includes a sleeve 12, a first limiting circular plate 13, an insertion tube 14, and a second limiting circular plate 15. The sleeve 12 is rotatably mounted on the slider 9. The first limiting circular plate 13 is installed on the end of the sleeve 12 near the slider 9. The insertion tube 14 is threaded in the sleeve 12. The second limiting circular plate 15 is installed on the end of the insertion tube 14 away from the slider 9. The active roller 6 has the same structure as the driven roller 10.

[0022] Rotating the insert 14 relative to the sleeve 12 causes the insert 14 and sleeve 12 to extend and retract relative to each other under the action of the thread, thereby adjusting the distance between the first limiting circular plate 13 and the second limiting circular plate 15. This is suitable for connectors of different diameters and widths. During operation, the emitting part of the photoelectric sensor 7 emits a horizontal laser beam. The piston rod of the push cylinder 11 extends and retracts, driving the slider 9 to move along the mounting plate 8. This causes the slider 9 to drive the driven roller 10 to approach the active roller 6 to clamp the connector. The outer wall of the sleeve 12 rolls in contact with the connector. The first limiting circular plate 13 and the second limiting circular plate 15 limit the outer side of the connector. At this time, the drive motor 5 drives the active roller 6 to rotate, causing the active roller 6 to rub against the connector, raising or lowering it. The action of the robotic arm mechanism 3 causes the robotic arm mechanism 4 to move the end face of the connector to below the main shaft 2, and to make the end face of the connector align with the main shaft 2. The milling cutter of spindle 2 is concentric, and drive motor 5 drives drive roller 6 to rotate, so that drive roller 6 rubs against the connector, thereby driving the connector upward. When the end face of the connector comes into contact with the laser beam emitted by photoelectric sensor 7, the laser beam is reflected. The receiving part of photoelectric sensor 7 receives the reflected laser beam, so that photoelectric sensor 7 generates an electrical signal. Drive motor 5 stops after receiving the electrical signal, thereby automatically positioning the height of the end face of the connector and completing automatic centering. At this time, spindle 2 drives the milling cutter to rotate and descend according to the program. The robotic arm mechanism 3 moves the connector in the horizontal plane through robotic arm mechanism 4, so that the milling cutter performs full milling on the end face of the connector. After the processing is completed, slider 9 drives driven roller 10 away from drive roller 6 to release the connector for unloading. The operation is simple and the work efficiency is high. Example 2

[0023] like Figures 4 to 6As shown, based on Embodiment 1, the robotic arm mechanism 3 includes a sliding sleeve 16, a first horizontal arm 17, and a second horizontal arm 18. The sliding sleeve 16 is mounted on the milling machine body 1. The first horizontal arm 17 is horizontally slidable back and forth within the sliding sleeve 16. The second horizontal arm 18 is rotatably and movable, horizontally mounted on the end of the first horizontal arm 17. The robotic arm mechanism 4 is mounted on the end of the second horizontal arm 18. It also includes a stepper motor 19, a lead screw 20, and a lead screw nut 21. The stepper motor 19 is mounted on the sliding sleeve 16. The lead screw 20 is rotatably mounted on the sliding sleeve 16. The output shaft of the stepper motor 19 is connected to the lead screw 20 via a transmission connection. The lead screw nut 21 is mounted on the first horizontal arm 17 and is threadedly connected to the lead screw 20. It also includes... The system includes a first flip motor 22, a second sliding sleeve 23, a second stepper motor 24, a second lead screw 25, and a second lead screw nut 26. The first flip motor 22 is installed at the end of the first horizontal arm 17. The output shaft of the first flip motor 22 is installed in the second sliding sleeve 23. The second horizontal arm 18 is slidably installed in the second sliding sleeve 23. The second stepper motor 24 is installed on the second horizontal arm 18. The second lead screw 25 is rotatably installed on the second horizontal arm 18. The output shaft of the second stepper motor 24 is connected to the second lead screw 25. The second lead screw nut 26 is installed on the second sliding sleeve 23. The second lead screw 25 and the second lead screw nut 26 are connected by a thread. The system also includes a second flip motor 27, which is installed at the end of the second horizontal arm 18. The robotic arm mechanism 4 is installed on the output shaft of the second flip motor 27.

[0024] The first flip motor 22 drives the second sliding sleeve seat 23 to rotate, which in turn drives the second horizontal arm 18 to rotate. This, in turn, drives the connecting part to rotate below or move it out of the main spindle 2 via the robot arm mechanism 4, facilitating loading and unloading. The first stepper motor 19 drives the first lead screw 20 to rotate, which is threadedly driven by the lead screw nut 21. This drives the first horizontal arm 17 to move horizontally back and forth along the sliding sleeve seat 16, thereby enabling the robot arm mechanism 4 to move the connecting part horizontally back and forth. The second stepper motor 24 drives the second lead screw 25 to rotate, which is threadedly driven by the lead screw nut 26. This drives the second horizontal arm 18 to move horizontally along the sliding sleeve seat 23, adjusting the left and right position of the connecting part. This allows the milling cutter of the main spindle 2 to perform full milling on the end face of the connecting part. The output shaft of the second flip motor 27 drives the robot arm mechanism 4 to rotate, thereby milling the end faces of both ends of the connecting part sequentially, improving processing efficiency.

[0025] like Figures 1 to 6As shown, this utility model discloses a milling device for the end face of a tower connector. During operation, the photoelectric sensor 7 first emits a horizontal laser beam. The push cylinder 11 actuates, rolling and clamping the middle part of the connector between the driven roller 10 and the driving roller 6. The first flip motor 22 moves the end face of the connector below the spindle 2. The first stepper motor 19 adjusts the front-to-back position of the connector, and the second stepper motor 24 adjusts the left-to-right position of the connector, making the end face of the connector concentric with the milling cutter of the spindle 2. The drive motor 5 drives the driving roller 6 to rotate, causing friction between the driving roller 6 and the connector, thus driving the connector upwards. When the end face of the connector contacts the laser beam emitted by the photoelectric sensor 7... When the laser beam is applied, it is reflected. The receiving part of the photoelectric sensor 7 receives the reflected laser beam, causing the photoelectric sensor 7 to generate an electrical signal. The drive motor 5 stops after receiving the electrical signal, thereby automatically positioning the end face height of the connector and completing automatic centering. At this time, the spindle 2 drives the milling cutter to rotate and descend according to the program. The rotation motor 22 and the stepper motor 24 work together to move the connector in the horizontal plane through the robot arm mechanism 4, so that the milling cutter can perform full milling on the end face of the connector. After one end face of the connector is milled, the rotation motor 27 drives the robot arm mechanism 4 to rotate the horizontal arm 2 by 180 degrees, and the above operation is repeated to mill the other end face of the connector.

[0026] The main functions achieved by this utility model are:

[0027] 1. Automatically positions and centers the end face height of the connector, which is simple to operate and highly efficient;

[0028] 2. Dual workstations can be set up to improve work efficiency;
