DETAILED DESCRIPTION

[0023] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.

[0024] Please refer to Figures 1-5 The utility model provides a technical scheme:

[0025] A phase friction welding machine driven by double servo parallel main shafts, comprising a phase friction welding machine 1 for realizing friction welding by double servo parallel main shaft driving, the phase friction welding machine 1 comprising:

[0026] The rotary welding machine unit 11 comprises a bed body 111, the top of the bed body 111 is provided with a main shaft box 112, the inside of the main shaft box 112 is fixedly installed with a main shaft clamp 113 through a main shaft, the top of the main shaft box 112 is fixedly installed with a first main motor 114 and a second main motor 115, the inside of the main shaft box 112 is fixedly installed with a first belt pulley 116 and a second belt pulley 117 at one end of the main shaft, and the first main motor 114, the second main motor 115, the first belt pulley 116 and the second belt pulley 117 are connected through a first synchronous belt 118 and a second synchronous belt 119 for realizing friction welding by double servo parallel main shaft driving;

[0027] The cleaning mechanism 12 is arranged at the top of the bed body 111 and is used for collecting and cleaning the debris generated during welding of the welded part.

[0028] Through parallel driving and synchronous control of the first main motor 114 and the second main motor 115, the rotation accuracy of the main shaft is effectively improved, the phase angle during the welding process can be accurately controlled, the phase deviation problem commonly seen in the traditional single servo motor system is avoided, thereby the quality and consistency of the welded joint are greatly improved, and since the double motors are used to drive the main shaft, the load capacity of the welding machine can be doubled relative to the single servo driving motor, a large-power friction welding machine can be manufactured, and larger parts can be welded.

[0029] Parallel driving of the two servo motors makes the system have greater redundancy, increases the stability and reliability of the system, and reduces the shaking and deviation during the welding process.

[0030] The servo motor has the characteristics of rapid response, can timely adjust the motion parameters of the main shaft, and is suitable for different workpieces and welding conditions.

[0031] According to different welding process requirements, the motion parameters of the main shaft can be flexibly adjusted through the control system, and various welding modes can be realized.

[0032] The double-servo parallel driving system can complete the welding process in a shorter time by increasing the output torque of the system, improving the welding efficiency, especially when dealing with large diameter and high strength material welding tasks, which has a significant advantage.

[0033] The double-servo parallel driving structure adopts two symmetrical servo motors, which are connected to the main shaft in the main shaft box 112 through the first synchronous belt 118, the second synchronous belt 119 and the first pulley 116, the second pulley 117. The speed and torque of the servo motor are adjusted in real time by the control system to ensure that the power output of the two motors remains synchronized. The speed deviation of the two motors is detected by the feedback sensor in the control system and corrected by the control algorithm to ensure the stability and accuracy of the main shaft rotation. This design not only improves the redundancy of the system, but also provides stronger power support when dealing with large torque loads, avoiding the power shortage problem that may occur when a single servo motor is driven.

[0034] The rotation control of the main shaft is completed by the PLC control system. The system accurately controls the rotation speed and angle of the servo motor according to the preset phase welding process parameters. The control system monitors the angular displacement of the main shaft in real time through the rotary encoder and feeds back to the control algorithm for correction, ensuring that the two motors run synchronously during the phase welding process and avoiding angle deviation. The system can also adjust the phase angle of the main shaft according to the welding process requirements to achieve precise welding between different workpieces. This control method combines high-precision encoder feedback and the fast response characteristics of servo motors to ensure that the phase control error during welding does not exceed ±0.5 degrees.

[0035] The feedback system monitors the rotation state in real time through the angle sensor installed on the main shaft and the rotary encoder of the servo motor. The angle sensor detects the change in the rotation angle of the main shaft, and the encoder monitors the speed of the servo motor. The control system dynamically adjusts the working parameters of the servo motor according to the feedback data to ensure that the main shaft can always maintain high-precision rotation under high load or complex welding conditions. The monitoring system also provides an alarm function. When the system detects that the synchronization error between the motors exceeds the preset threshold, the system will automatically adjust or stop running to prevent welding defects.

[0036] In this embodiment, the top of the bed body 111 is fixedly installed with a fixed clamp 2 for clamping the welding piece.

[0037] Place the welding piece in the clamping groove of the fixed clamp 2 to ensure that the contact surface of the welding piece and the clamp is in full contact, and clamp the welding piece through the air cylinder

[0038] In this embodiment, the top of the bed body 111 is fixedly installed with an auxiliary clamp 3 for pressing the bottom end of the welding piece.
