Description

Technical Field

[0001] This utility model relates to the field of drag device technology, and in particular to a dual-motor synchronous drag device used on a high-precision grinding and polishing machine. Background Technology

[0002] Precision grinding and polishing machines are equipment used for precision surface processing of materials, capable of processing cylindrical, planar, and other shapes with nanometer-level precision; this equipment is suitable for grinding and polishing various materials such as metals, ceramics, glass, semiconductor materials, and rock and mineral samples;

[0003] The dragging device on existing polishing machines is generally driven by a single motor. However, single motor drive has insufficient precision under high power, high load or complex motion trajectory. Moreover, the consistency of its speed and position during the dragging of the workpiece is poor. It is prone to vibration and error caused by asynchronous movement, resulting in poor uniformity of the polished surface of the workpiece, which affects product quality and needs to be improved.

[0004] Therefore, this application proposes a dual-motor synchronous drive device for use on a high-precision grinding and polishing machine to solve the problems in the background art.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0010] The limiting mechanism includes a ring plate, a bracket, an electric push rod, and a limiting block. The two transmission wheels are each fixedly fitted with a ring plate, and both ring plates are in contact with the drag belt. The coordinated design between the control module, the two motors, the two encoders, the two gearboxes, and the limiting mechanism improves the accuracy of the workpiece dragging, thereby improving product quality.

[0026] This utility model provides a dual-motor synchronous drive device for use on a high-precision polishing machine, referring to... Figures 1-4 A dual-motor synchronous drive device for use on a high-precision polishing machine includes a drive belt 1 for the high-precision polishing machine, a motor 9, and a limiting mechanism 4.

Transmission wheels 6 are fixedly installed at one end of both output shafts 5. Both transmission wheels 6 are connected to the traction belt 1. The two transmission wheels 6 can be replaced according to the type or specification of the material. Both gearboxes 3 are provided with limiting mechanisms 4, and the two limiting mechanisms are respectively connected to the two transmission wheels 6.

[0028] The limiting mechanism includes a ring plate 41, a bracket 42, an electric push rod 43, and a limiting block 44. The ring plate 41 is fixedly sleeved on both transmission wheels 6, and both ring plates 41 are in contact with the drag belt 1. The coordinated design between the control module 7, two motors 9, two encoders 10, two gearboxes 3, and the limiting mechanism 4 improves the accuracy of dragging the workpiece, thereby improving product quality. Moreover, it can achieve mechanical positioning and zeroing to further eliminate errors and improve accuracy.

[0029] In this embodiment, a bracket 42 is fixedly connected to the top of each of the two gearboxes 3. An electric push rod 43 is fixedly installed on the bracket 42 for moving and adjusting the two limit blocks 44. A control module 7 is fixedly installed on one of the two bases 2. Both electric push rods 43 are connected to the control module 7. The two electric push rods 43 are driven and controlled by a preset program in the control module 7.

[0030] In this embodiment, the output end of the electric push rod 43 is fixedly connected to a limiting block 44, the limiting block 44 is engaged with the ring plate 41, and the ring plate 41 is provided with multiple limiting grooves 45, all of which are adapted to the limiting block 44. Through the interaction between the limiting block 44 and the limiting grooves 45, and the transmission of the ring plate 41, the effect of accurately positioning the transmission wheel 6 is achieved.

[0031] In this embodiment, multiple limiting grooves 45 are arranged at equal intervals on the ring plate 41, and the number of multiple limiting grooves 45 can be flexibly set according to actual needs.

[0032] In this embodiment, an encoder 10 is installed on one side of each of the two gearboxes 3. The two encoders 10 are connected to the two output shafts 5 respectively. Both encoders 10 are connected to the control module 7. Through the function of the two encoders 10, the rotational speed of the two output shafts 5 can be monitored in real time. At the same time, the monitored information is transmitted to the control module 7. Meanwhile, the control module 7 analyzes and judges the information through its internal preset program and sends commands to the two motors 9. At the same time, the two motors 9 control their operating state according to the adjusted signal and compensate for synchronization error to ensure that the motion state of the two motors 9 is consistent.

[0033] In this embodiment, supports 8 are fixedly connected to both bases 2, and motors 9 are fixedly installed on both supports 8. The output ends of the two motors 9 are respectively connected to the drive shafts on one side of the two gearboxes 3. Both motors 9 are connected to the control module 7. The device is installed at the position corresponding to the feed inlet of the high-precision polishing machine through the action of the two bases 2. Then, through the drive of the two motors 9 and the transmission through the cooperation of the two gearboxes 3, the two output shafts 5 rotate synchronously. At the same time, the two output shafts 5 drive the two transmission wheels 6 to rotate synchronously and transmit with the drag belt 1, thereby achieving the effect of dragging and conveying the processed parts. Both motors 9 are servo motors, and the control module 7 is a PLC controller. By comparing the feedback values ​​of the two encoders 10 with the command values, the synchronization error is calculated, and the output signals of the two motors 9 are adjusted through the algorithm.

[0034] Working principle: When in use, first turn on the power and drive and control the two motors 9 and the electric push rod 43 through the preset program in the control module 7;

[0035] First, the device is installed at a position corresponding to the feed inlet of the high-precision polishing machine by means of two bases 2. Then, driven by two motors 9 and driven by two gearboxes 3, the two output shafts 5 rotate synchronously. At the same time, the two output shafts 5 drive the two transmission wheels 6 to rotate synchronously and drive them to the drag belt 1, thereby achieving the effect of dragging and conveying the processed parts.

[0036] During this process, the two encoders 10 can monitor the rotational speed of the two output shafts 5 in real time, and transmit the monitored information to the control module 7. The control module 7 analyzes and judges the information through its internal preset program and sends commands to the two motors 9. The two motors 9 control their operating status according to the adjusted signals and compensate for synchronization errors to ensure that the motion state of the two motors 9 is consistent. Thus, by working together, the two motors 9 solve the problem of insufficient accuracy of existing single motor drives under high power, high load or complex motion trajectory, ensure the consistency of speed and position during motion, reduce vibration and errors caused by asynchrony, thereby ensuring the uniformity of the polished surface and improving product quality.

[0037] Subsequently, when the two motors 9 stop working, the extension drive of the electric push rod 43 causes the limiting block 44 to interact with one of the multiple limiting grooves 45 on the ring plate 41, and the limiting block 44 engages with its limiting groove 45. At this time, through the interaction between the limiting block 44 and the limiting groove 45, and the transmission of the ring plate 41, the transmission wheel 6 is precisely positioned, thereby achieving mechanical positioning and zeroing to further eliminate errors.

[0038] The technological advancements achieved by this invention compared to existing technologies are: improved accuracy in conveying processed parts through the coordination of various components, thereby improving product quality; furthermore, mechanical positioning and zeroing can be achieved to further eliminate errors and improve accuracy; and the structure is simple and more practical.
