Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, the dual-arm grinding device of this utility model embodiment includes a base 10. A frequency converter 12 is installed in the base 10 through a fixing plate 11. The frequency converter 12 is electrically connected to a dual-output shaft motor 20. The output end of the dual-output shaft motor 20 is connected to a drive wheel 30. The drive wheel 30 is sleeved on a cantilever 40 through a belt 31. A grinding device (not shown in the figure) is installed at the output end of the cantilever 40. The input end of the cantilever 40 is installed in a fixing device 70. The fixing device 70 is installed on an angle adjustment device 50. The angle adjustment device 50 is rotatably installed on the end face of the dual-output shaft motor 20.

[0022] The angle adjustment device 50 includes an adjustment housing 52 rotatably mounted on the end face of the dual-output shaft motor 20. An adjuster 51 is mounted on the adjustment housing 52. A copper bushing 53 is hinged inside the adjustment housing 52, and the input end of a connecting rod 41 is sleeved inside the copper bushing 53. A fixing device 70 is installed on the output end of the connecting rod 41. The angle adjustment device 50 is used to adjust the angle of the cantilever 40 to adapt to the grinding requirements of different workpieces. The copper bushing 53 reduces the frictional resistance of the cantilever 40 during operation, enhancing operational stability. The adjustment housing 52 is rotatably mounted on the end face of the dual-output shaft motor 20 via a motor flange seat 21. A Teflon gasket 22 is provided between the motor flange seat 21 and the dual-output shaft motor 20. Sound insulation cotton 23 is installed inside the Teflon gasket 22. The Teflon gasket 22 and the sound insulation cotton 23 reduce vibration and noise during equipment operation, thereby improving grinding accuracy and the comfort of the operating environment.

[0023] The fixing device 70 includes an adjustment box 71 mounted on the angle adjustment device 50. The adjustment box 71 is a box structure with a through-hole in the middle. The front end of the adjustment box 71 has a U-shaped groove 72 for mounting the cantilever 40, and the input end of the cantilever 40 has a corresponding mounting groove 73. The adjustment box 71 and the cantilever 40 are fixed together by a fixing bolt 74. The rear end of the adjustment box 71 and the output end of the connecting rod 41 also have mounting grooves 73, and the adjustment box 71 and the connecting rod 41 are also fixed together by fixing bolts 74. When installing the cantilever 40, first fix the adjustment box 71 to the connecting rod, then pass the fixing bolt 74 through the input end of the cantilever 40, then push the cantilever 40 into the U-shaped groove 72 of the adjustment box 71, and finally put on the belt 31. By setting the fixing device 70, this equipment can be used with cantilever 40 of different specifications, and the installation process is simple and quick.

[0024] A correction device 42 is provided on the cantilever 40. The correction device 42 includes an adjusting plate 43 rotatably mounted in the adjusting box 71 via a fixing bolt 74. The adjusting plate 43 abuts against an adjusting bolt 44. A stepped sleeve 45 passes through the adjusting bolt 44 and is installed between the adjusting plate 43 and the inner wall of the adjusting box 71. A spring 46 is sleeved between the outer wall of the adjusting box 71 and the end face of the adjusting bolt 44. The correction device 42 is used to adjust the position of the grinding device to ensure grinding accuracy.

[0025] The dual-output shaft motor 20 is surrounded by a motor housing 24, on which a switch box 60 is mounted. The switch box 60 contains a power switch 61, an emergency stop button 62, a frequency converter operation panel 63, and a motor speed control button 64. The power switch 61 is electrically connected to the emergency stop button 62, the frequency converter operation panel 63, and the motor speed control button 64. The emergency stop button 62 is used to quickly cut off the power supply in emergencies to ensure operational safety. The frequency converter operation panel 63 is used to control the frequency converter 12 and is also connected to the motor speed control button 64. The motor speed control button 64 is used to adjust the speed of the dual-output shaft motor 20 to achieve grinding operations of varying intensities. By setting the motor speed control button 64, the grinding intensity can be flexibly adjusted to meet diverse processing needs.

[0026] The base 10 also houses a fan 13, which is electrically connected to the power switch 61 for heat dissipation, ensuring stable operation of the equipment over a long period. The bottom of the base 10 is equipped with anti-vibration feet 14, which reduce vibration during operation and improve grinding precision.

[0027] During operation, the equipment is first started via power switch 61, and the dual-shaft motor 20 begins to run under the control of frequency converter 12. The motor's output drives the drive wheel 30 to rotate, and the drive wheel 30 transmits power to the cantilever 40 via belt 31. The cantilever 40 then drives the grinding device to perform grinding operations on the workpiece. During the grinding process, the operator can adjust the speed of the dual-shaft motor 20 via the frequency converter control panel 63 and the motor speed control button 64 to meet different grinding intensities.

[0028] The dual-arm grinding system in this invention employs a dual-output shaft motor 20 to synchronously drive two grinding arms, achieving synchronized operation of the two arms and significantly improving grinding efficiency. Through the cooperation of the frequency converter 12 and the dual-output shaft motor 20, precise control of the motor speed is achieved, flexibly adapting to grinding requirements of varying intensities. The application of the fixing device 70 makes it suitable for cantilever arms 40 of different specifications, and the installation process is simple and quick. By setting up a correction device 42 and an angle adjustment device 50, the position and angle of the grinding device can be precisely adjusted to ensure grinding accuracy. The design of the copper bushing 53 and Teflon gasket 22 effectively reduces frictional resistance and equipment vibration during cantilever arm 40 operation, improving operational stability and grinding accuracy.
