Description

Technical Field

[0001] The present invention relates to the technical field of electric chucks, and in particular to an electric chuck device based on LORA MODBUS wireless communication. Background Art

[0002] LORA wireless communication provides a low-power, long-distance wireless transmission method. In the electric chuck device, LORA technology enables the chuck controller to communicate wirelessly with the central control system or other equipment (such as PLC, HMI, etc.) without physical connection, which improves the flexibility of deployment and the convenience of maintenance; MODBUS protocol combined with LORA wireless technology, MODBUS commands and data packets can be transmitted wirelessly to achieve remote control and status monitoring of the electric chuck; using LORAMODBUS wireless communication, the operator or central control system can send instructions wirelessly, such as opening and closing the chuck, adjusting the clamping force, etc., and can also receive status feedback of the chuck, such as the current clamping status, fault alarm, etc.

[0003] In the existing patent CN115476059A, an electric intelligent chuck is disclosed, including a chuck body, a bearing seat, a driving mechanism and a rotating mechanism. The chuck body is mounted on the bearing seat, the driving mechanism is mounted in the bearing seat, and can drive the claw assembly on the chuck body to open and close, the rotating mechanism can drive the chuck body to rotate, and the driving mechanism includes a driving motor, a transmission assembly, a toothed disc assembly and a bridge gear set. The driving motor drives the toothed disc assembly to rotate through the transmission assembly, and drives the claw assembly on the chuck body to open and close through the bridge gear set. The driving mechanism in the present invention adopts the form of a motor combined with a gear, and the overall moment of inertia is smaller, and a high speed can be achieved. At the same time, the motor driving accuracy is higher, the applicability is wider, and there is no need to specially set up an airtight structure, and the cost is effectively reduced. Since the motor peripherals are located outside the bearing seat, no collector ring is required to arrange the circuit, the service life is long, and the chuck is more durable. At the same time, the motor is located outside the chuck, which is easy to maintain and repair.

[0004] In the above structure, the material can be clamped, but during the feeding process, the chuck gradually approaches the material. Since the feeding speed of the chuck is difficult to control and the feed drive requires reaction time, when the chuck contacts the material, when the chuck feed speed is fast, a larger clamping force is generated, forcing the chuck to exert a greater pressure on the material, thereby damaging the material. When the chuck feed speed is slow, the contact time between the chuck and the material is prolonged, reducing the processing efficiency, wasting time, and not conducive to the chuck clamping the material.

Since the feeding component will quickly collide with the workpiece during high-speed movement, in order to reduce the speed of the feeding component when it is close to the workpiece and enter a deceleration movement state, the driving mechanism is disconnected from the feeding component by the connecting component, and the driving mechanism is stopped.

At the same time, LORA MODBUS wireless communication transmits data, completes the clamping operation of the workpiece, starts the rotating mechanism, forces the turntable to rotate, and thus adjusts the processing direction of the workpiece; in summary, the electric chuck device based on LORA MODBUS wireless communication of the present application utilizes the segmented combination of the driving mechanism and the feed assembly to distinguish the feed assembly into high speed and low speed, so that the feed assembly adopts high-speed motion in the early stage, so that the feed assembly can quickly reach the vicinity of the workpiece, and utilizes the self-motion of the feed assembly to drive the feed assembly to decelerate to a reasonable speed, forcing the driving mechanism to be connected to the feed assembly, so that the feed assembly enters a low-speed motion state, and realizes the transition from high-speed motion to low-speed motion of the feed assembly, avoiding the reaction time of the device, and improving the device's control over the speed of the feed assembly. The speed of the feed assembly is increased in the early stage, so that the feed assembly can quickly approach the workpiece, thereby improving the processing efficiency, and a smaller force is generated when the device and the workpiece are fitted in the later stage, thereby protecting the workpiece.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0034] Embodiment 1:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the electric chuck device based on LORAMODBUS wireless communication of the present invention comprises a support ring 1, a bearing is provided on the support ring 1 and a ring-shaped turntable 2 is connected thereto, and a rotating mechanism 3 for driving the turntable 2 to rotate is provided on the support ring 1;

[0036] The turntable 2 is provided with a driving mechanism 4, the output end of the driving mechanism 4 is provided with a connecting component 5, and the turntable 2 is provided with a feeding component 6 for clamping the workpiece, and the driving mechanism 4 acts on the feeding component 6 through the connecting component 5;

[0037] The turntable 2 is provided with a sliding assembly 7, a transmission assembly 8 is provided on the sliding assembly 7, and a brake assembly 9 is provided on the sliding assembly 7. When decelerating, the sliding assembly 7 moves so that the transmission assembly 8 is connected with the feeding assembly 6. The feeding assembly 6 moves through the transmission assembly 8 to act on the brake assembly 9, and the brake assembly 9 forces the feeding assembly 6 to decelerate.

[0038] The driving mechanism 4 starts running at a low speed and acts on the feeding assembly 6 through the connecting assembly 5, forcing the feeding assembly 6 to run at a low speed, thereby achieving the transition of the feeding assembly 6 from a high speed to a low speed.

[0039] Working principle: When clamping the workpiece, use the traction equipment to pass the workpiece through the turntable 2, use the connecting component 5 to connect the driving mechanism 4 with the feeding component 6, start the driving mechanism 4, and under the action of the connecting component 5, the feeding component 6 moves, and multiple feeding components 6 gradually approach the workpiece at the same time. When the feeding component 6 is close to the workpiece and needs to be decelerated, the sliding component 7 is used to drive the transmission component 8 and the brake component 9 to move, forcing the transmission component 8 to synchronize with the movement of the feeding component 6, and the preparation action is completed. At this time, the high-speed action is completed. Because the feeding component 6 will quickly conflict with the workpiece during high-speed movement, in order to reduce the speed of the feeding component 6 when it is close to the workpiece, it enters a deceleration movement state, and the connecting component 5 is used to disconnect the driving mechanism 4 from the feeding component 6, and the driving mechanism 4 is stopped. Due to inertia, the feeding component 6 continues to move forward. Under the action of the component 8, the force of the feed assembly 6 is transmitted to the transmission component 8, so that the force is transmitted to the brake component 9. The brake component 9 brakes the feed assembly 6 to decelerate the feed assembly 6, so that the feed assembly 6 enters a decelerated motion state. When the feed assembly 6 reaches a certain speed, it is fed back to the system. At this time, the feed assembly 6 is close to the workpiece, and the connecting component 5 is used to connect the drive mechanism 4 and the feed assembly 6 again, and the sliding component 7 drives the brake component 9 and the transmission component 8 to retreat, so that the transmission component 8 is separated from the feed assembly 6. Since the speed of the feed assembly 6 is slow, the drive mechanism 4 is started at this time. Under the action of the connecting component 5, the drive mechanism 4 drives the feed assembly 6 to move slowly until multiple feed assemblies 6 are in contact with the workpiece to form a clamp for the workpiece, and the drive mechanism 4 is stopped. At the same time, LORA MODBUS wireless communication transmits data, completes the clamping operation of the workpiece, starts the rotating mechanism 3, forces the turntable 2 to rotate, and thus adjusts the processing direction of the workpiece; in summary, the electric chuck device based on LORAMODBUS wireless communication of the present application utilizes the segmented combination of the driving mechanism 4 and the feeding assembly 6 to distinguish the feeding assembly 6 into high speed and low speed, so that the feeding assembly 6 adopts high-speed movement in the early stage, so that the feeding assembly 6 can quickly reach the vicinity of the workpiece, and utilizes the self-movement of the feeding assembly 6 to drive the feeding assembly 6 to decelerate to a reasonable speed, forcing the driving mechanism 4 to be connected with the feeding assembly 6, so that the feeding assembly 6 enters a low-speed movement state, and realizes the transition from high-speed movement to low-speed movement of the feeding assembly 6, avoiding the reaction time of the device, and improving the control of the speed of the feeding assembly 6 by the device. In the early stage, the speed of the feeding assembly 6 is increased, so that the feeding assembly 6 can quickly approach the workpiece, thereby improving the processing efficiency, and in the later stage, when the device and the workpiece are in contact, a smaller force is generated, thereby protecting the workpiece.

[0049] like Figure 4 and Figure 5 As shown, in the electric chuck device based on LORA MODBUS wireless communication of the present invention, a detection component 10 for detecting speed is arranged on the rotating wheel 907, the detection component 10 includes a signal gear ring 1001 fixedly mounted on the rotating wheel 907, a support rod 1002 is arranged on the turntable 2, a wheel speed sensor 1003 adapted to the signal gear ring 1001 is installed on the support rod 1002, and the wheel speed sensor 1003 is electrically connected to the control system to control the output speed of the motor 2 402.

[0050] Working principle: When clamping the workpiece, the workpiece is passed through the turntable 2 by using the traction device, and the electric push rod 502 is started. Under the action of the support block 501, the output end of the electric push rod 502 drives the support frame 503 to move, and the support frame 503 drives the friction sleeve 504 to move, forcing the sliding sleeve 505 to move on the rotating rod 604 until the friction sleeve 504 moves to contact with the sleeve 403, so that the sleeve 403, the rotating rod 604 and the friction sleeve 504 form a whole;

[0051] Start the second motor 402, the output shaft of the second motor 402 rotates to drive the sleeve 403 to rotate, and the sleeve 403 drives the rotating rod 604 and the threaded rod 601 to rotate. Under the action of the turntable 2, the support rod 602 and the clamping block 603 move forward, so that the clamping block 603 gradually approaches the workpiece, and multiple clamping blocks 603 move at high speed. When the clamping block 603 moves to a certain position, it is necessary to decelerate the clamping block 603 so that the speed of the clamping block 603 drops to a reasonable speed to avoid rapid contact between the clamping block 603 and the workpiece;

[0052] Start the electric push rod 2 701, so that the output end of the electric push rod 2 701 drives the connecting plate 702 and the supporting platform 703 to move, and the supporting platform 703 drives the transmission assembly 8 and the brake assembly 9 to move synchronously, so that the rotating gear 803 is meshed with the spur rack 804, and the connection between the driving mechanism 4 and the rotating rod 604 is disconnected at the same time, and the electric push rod 1 502 is started in the reverse direction. Under the action of the supporting block 501, the output end of the electric push rod 1 502 drives the supporting frame 503 to move in the reverse direction, and the supporting frame 503 drives the friction sleeve 504 to move in the reverse direction, forcing the sliding sleeve 505 to move on the rotating rod 604 until the friction sleeve 504 moves to disengage from the sleeve 403, so that the sleeve 403 is separated from the rotating rod 604;

[0053] Due to the effect of inertia, the rotating rod 604 drives the threaded rod 601 to continue to rotate. At this time, since the spur rack 804 is meshed with the rotating gear 803, the spur rack 804 continues to move forward with the support rod 602, so that the rotating gear 803 rotates, and the rotating gear 803 drives the rotating shaft 1 802 to rotate, so that the transmission gear 1 805 rotates, forcing the transmission gear 2 808 to rotate, and the transmission gear 2 808 drives the rotating shaft 2 806 to rotate. Under the transmission action of the pulley 809 and the belt 8010, the rotating shaft 3 807 is forced to rotate, and the rotating shaft 3 807 drives the rotating disk 901 to rotate, and the rotating disk 901 drives the connecting rod 902 to move, and the connecting rod 902 reciprocates. Under the guiding action of the guide block 904, the movable rod 903 drives the L-shaped rod 905 to move back and forth, so that the brake pad 906 is intermittently in contact with the rotating wheel 907, so that the brake pad 906 forms a braking effect on the rotating wheel 907, thereby gradually reducing the rotation speed of the rotating rod 604;

[0054] Since the rotating wheel 907 drives the signal gear ring 1001 to rotate, the wheel speed sensor 1003 detects the signal gear ring 1001 in real time, measures the rotation speed of the rotating wheel 907, and transmits the speed to the control system. The rotation speed of the rotating rod 604 is reduced to a certain speed until the clamping block 603 enters the low-speed zone. The control system analyzes the speed value and controls the output speed of the motor 2 402;

[0055] The electric push rod 1 502 is started again. Under the action of the support block 501, the output end of the electric push rod 1 502 drives the support frame 503 to move, and the support frame 503 drives the friction sleeve 504 to move, forcing the sliding sleeve 505 to move on the rotating rod 604 until the friction sleeve 504 moves to contact the sleeve 403, so that the sleeve 403, the rotating rod 604 and the friction sleeve 504 form a whole; at the same time, the electric push rod 2 701 is started, so that the output end of the electric push rod 2 701 drives the connecting plate 702 and the supporting platform 703 to move and retreat to the original position. At this time, the rotating gear 803 is separated from the spur rack 804;

[0056] The output speed of the second motor 402 is controlled by the control system, so that the speed of the output shaft of the second motor 402 is adapted to the low speed of the rotating rod 604. The output speed of the rotating rod 604 is controlled by the second motor 402, and the rotating rod 604 is controlled to run at a low speed, thereby forcing the clamping block 603 to run slowly until it fits with the workpiece, and the second motor 402 is stopped to form a clamping effect on the workpiece, and at the same time, the data is transmitted by LORA MODBUS wireless communication;

[0057] When the workpiece needs to be processed in multiple directions, the motor 301 is started, and the output shaft of the motor 301 rotates to drive the driven gear 303 to rotate, thereby rotating the turntable 2 to adjust the processing circumferential direction of the workpiece, thereby cooperating with the traction equipment to realize processing of different positions of the workpiece;

[0058] The setting of the rotating mechanism 3 facilitates the rotation of the turntable 2, so that the turntable 2 can be rotated to a reasonable position, so that the device can process all four sides of the workpiece, and the flexibility of the device is improved; the setting of the driving mechanism 4 provides power, which is convenient for driving the sleeve 403 to rotate, so that under the action of the connecting component 5, the rotating rod 604 rotates with the sleeve 403, which is conducive to controlling the speed of the rotating rod 604, thereby controlling the feeding speed of the clamping block 603; the setting of the feeding component 6 can use the power of the driving mechanism 4 to gradually push the clamping block 603 to the workpiece, so that the clamping block 603 approaches the workpiece at a certain speed, so that the movement speed of the clamping block 603 is increased. The arrangement of the connecting assembly 5 can realize the connection between the driving mechanism 4 and the feeding assembly 6, thereby realizing the speed control of the rotating rod 604, so that the device presents three speed intervals, namely high-speed movement, deceleration movement and low-speed movement, realizing the control effect of the driving mechanism 4 on the feeding assembly 6, and improving the rationality and flexibility of the device; the arrangement of the sliding assembly 7 can drive the synchronous movement of the transmission assembly 8 and the brake assembly 9, so that the transmission assembly 8 is connected to the feeding assembly 6, forcing the self-movement of the feeding assembly 6 to drive the transmission assembly 8 to move, and at the same time, the transmission assembly 8 and the brake assembly 9 can be retracted to the original position, so that the transmission assembly 8 and the feeding assembly 6 The transmission assembly 8 is not connected, so that the device forms a low-speed motion state; the setting of the transmission assembly 8 can make the spur rack 804 mesh with or separate from the rotating gear 803. When the spur rack 804 meshes with the rotating gear 803, the movement force of the support rod 602 is transmitted to the brake assembly 9, so as to achieve the deceleration of the feed assembly 6. When the spur rack 804 is separated from the rotating gear 803, the high-speed or low-speed operation of the feed assembly 6 is achieved. The setting of the transmission gear 1 805 and the transmission gear 2 808 is convenient for amplifying the movement of the support rod 602, so that the number of braking times of the brake assembly 9 is increased, and the braking effect is improved; the setting of the brake assembly 9 is convenient for achieving The deceleration effect of the rotating rod 604 reduces the travel speed of the clamping block 603, realizes the braking of the feeding assembly 6, and converts the circular motion into a linear reciprocating motion, so that the brake pad 906 continuously forms a point brake on the rotating wheel 907, thereby improving the braking effect, while protecting the brake pad 906 and the rotating wheel 907, and increasing the service life of the device; the setting of the detection component 10 facilitates the speed detection of the rotating wheel 907, which is beneficial to the speed control of the device, and at the same time transmits the speed to the control system, which is beneficial to the control system to reasonably drive the device, thereby realizing the device's control of relatively high speed, deceleration and low speed, and improving the rationality of the device;

[0059] This solution divides the movement speed of the clamp 603 into a high-speed zone, a deceleration zone and a low-speed zone, thereby achieving control of the movement speed of the clamp 603 and controlling the fit between the clamp 603 and the workpiece; the driving mechanism 4 is combined with the feeding assembly 6 in sections to distinguish the feeding assembly 6 from high-speed and low-speed, so that the feeding assembly 6 adopts high-speed movement in the early stage, so that the feeding assembly 6 can quickly reach the vicinity of the workpiece, and the feeding assembly 6 is driven to decelerate to a reasonable speed by its own movement, forcing the driving mechanism 4 to be connected with the feeding assembly 6, so that the feeding assembly 6 enters a low-speed movement state, and the transition from high-speed movement to low-speed movement of the feeding assembly 6 is achieved, thereby avoiding the reaction time of the device, improving the control of the speed of the feeding assembly 6 by the device, increasing the speed of the feeding assembly 6 in the early stage, so that the feeding assembly 6 can quickly approach the workpiece, improving the processing efficiency, and generating a smaller force when the device fits with the workpiece in the later stage, thereby protecting the workpiece; and the solution realizes data transmission and control between devices based on LORA MODBUS wireless communication, solves the problems of limited transmission distance, difficult wiring and high maintenance cost, and improves the stability and reliability of the industrial automation system.
