[0008] According to the above technical solution, the free end of the telescopic elastic rod is fixedly connected to the inclined block, and the reciprocating screw rotates through the surface of the processing table to effectively maintain its relative position and avoid dislocation or warping caused by processing.

[0009] According to the above technical solution, the surface of the base is provided with an auxiliary processing device for rotating the pipe to facilitate processing and restrict it to avoid improper influence on the pipe during processing. The auxiliary processing device includes a sliding table, which is slidably installed on the surface of the base, and a rotating processing mechanism is provided on the inner wall of the sliding table. A rotating wheel is rotatably installed on the surface of the rotating processing mechanism, and a sleeve plate is sleeved on the end of the rotating wheel close to the processing table. A telescopic linkage plate is fixedly installed on the surface of the clamping plate 2, and a C-shaped plate is fixedly installed on the surface of the sleeve plate, and a fixed plate is fixedly installed on the end of the C-shaped plate away from the sleeve plate. At this time, the rotation of the pipe realizes the controllability of multi-angle processing of the pipe, improves the convenience of the pipe processing process, and can ensure that the pipe always maintains a stable rotation posture during processing, so that the processing tool can act evenly on each part of the pipe, avoiding processing errors caused by improper manual operation.

The surface of the cleaning disk is provided with bristles, which knock on the surface of the pipe to improve the cleaning effect. At the same time, knocking on it will shake off the impurities attached to the surface of the pipe through vibration, further improving the surface cleanliness and appearance.

[0014] The present invention provides a fixing device for laser processing of metal pipes, which has the following beneficial effects: (1) The fixing device for laser processing of metal pipes drives the sliding plate to move downward by the output end of the hydraulic cylinder, and the movement of the sliding plate drives the clamping plate 1 to move at the same time. The movement of the clamping plate 1 clamps the pipe, thereby improving the stability and accuracy of the pipe during the processing and avoiding shaking or vibration of the pipe due to improper clamping during the processing, thereby affecting the processing accuracy and quality of the finished product. The movement of the inclined block drives the sliding plate to move in the direction close to the pipe, and the movement of the sliding plate drives the clamping plate 2 to move.

[0015] (2) The fixture for laser processing of metal pipes is driven to rotate the wheel by rotating the processing mechanism. At this time, the wheel contacts the pipe under the action of the rotating sleeve, and the rotation of the wheel drives the pipe to rotate. At this time, the rotation of the pipe realizes the controllability of multi-angle processing of the pipe, improves the convenience of the pipe processing process, and can ensure that the pipe always maintains a stable rotation posture during the processing, so that the processing tool can act evenly on each part of the pipe, avoiding processing errors caused by improper manual operation, and ensuring high precision of the processing size. The automatic rotation can help the pipe to rotate accurately at different processing stages to ensure the smooth progress of the processing process.

[0016] (3) The fixture for laser processing of metal pipes drives the C-shaped plate to move toward the pipe by moving the sleeve plate. The movement of the C-shaped plate drives the fixing plate to move until the pipe is limited, thereby preventing the pipe from being improperly shaped or bent during processing, thereby damaging the equipment and even causing harm to the staff.

[0017] (4) The fixing device for laser processing of metal pipes drives the cleaning disk to rotate by the rotating wheel under the action of the rotating processing mechanism. At the same time, the cleaning disk drives the brush to rotate to clean the end face of the pipe to prevent dust or impurities from affecting the subsequent processing or treatment effect, making the surface of the pipe more tidy, thereby improving the processing accuracy and smoothness. At the same time, the telescopic support plate will adapt to the height of pipes of different sizes. The telescopic support plate moves under the action of the pipe and drives the connecting plate to move. At the same time, the movement of the connecting plate drives the brush plate to move. At this time, the end face of the pipe away from the sliding table is cleaned by the self-rotation of the pipe, and both end faces of the pipe are cleaned, making the subsequent reversing processing process smoother and more stable.

[0018] (5) The fixture for laser processing of metal pipes drives the rotating shaft to rotate by rotating the second roller, and the rotating shaft drives the eccentric wheel to rotate. The eccentric wheel rotates to contact and squeeze the knocking plate to move upward. The knocking plate moves upward to knock on the surface of the pipe, thereby improving the cleaning effect. At the same time, knocking on it will shake off the impurities attached to the surface of the pipe through vibration, further improving the surface cleanliness and appearance.
