The fixed plate 2 is also provided with an adjusting component which can drive the supporting square rod 202 to axially move. Through adjusting part, can radially adjust the axial projecting amount of two support square poles 202 along the pipeline to the instruction scale 204 on the cooperation support square pole 202 outer wall can guarantee that the device can both the centering centre gripping installation on each pipe diameter pipeline. And, the two support square rods 202 are arranged, so that two positioning points can determine a straight line, and the eccentricity of the pipeline can be eliminated to the greatest extent, so that the centering clamping installation of the pipeline is ensured, and the concentricity between the processing equipment and the workpiece is ensured. In this embodiment, the lower end of the square support rod 202 is connected with support legs 203 arranged along the axial direction of the pipe. The support legs 203 are thus provided to further prevent axial deflection of the pipe.

The clamping mechanism of the device can realize the clamping of the multi-pipe diameter range, the clamping is stable and firm, simultaneously, two support square rods 202 which are radially arranged along the pipe and can axially adjust the position are utilized, and the centering clamping installation of the device on the pipe with each pipe diameter can be ensured by matching with indication scales 204 on the outer wall of the support square rods 202. Therefore, through the device, the centering clamping of the clamping device on the pipeline can be ensured, so that the concentricity between the processing equipment clamped on the pipeline and the workpiece can be ensured, the positioning with high precision can be realized, and the processing quality is ensured.

In this device, in order to guide the moving path of the support square bar 202, a square chute 201 passing through the entire fixing plate 2 in the radial direction of the pipe is provided on the plate surface of the fixing plate 2, and the support square bar 202 is slidably mounted in the square chute 201. Meanwhile, in order to adjust the protruding amount of the supporting square bar 202, the adjusting assembly of the device comprises a supporting adjusting screw 205 which extends in the same direction as the supporting square bar 202 and is in threaded connection with the supporting square bar 202 at the lower outer wall. The supporting adjusting screw 205 is arranged in the square chute 201, and a limiting block 206 rotatably arranged on the inner wall of the square chute 201 is fixedly arranged on the upper portion of the supporting adjusting screw 205. The upper end of the supporting adjusting screw 205 extends out of the fixed plate 2 and is connected with an adjusting knob 1. When the pipe diameter is required to be positioned by a certain pipe diameter, the supporting adjusting screw rod 205 is driven to rotate by rotating the adjusting knob 1, and when the supporting adjusting screw rod 205 rotates, the supporting adjusting screw rod drives the supporting square rod 202 to radially move to the scale of the specified pipe diameter along the pipeline, so that the pipe diameter positioning adjustment is realized.

In addition, in order to avoid random rotation of the clamping arm adjusting screw, an adjusting knob 1 is connected to the control end of the clamping arm adjusting screw. When a certain pipe diameter needs to be clamped, the clamping arm adjusting screw rod of the clamping mechanism can be driven to rotate by pressing the rotary adjusting knob 1, so that the clamping arm 302 is adjusted to a proper position, and a proper clamping force is generated to clamp a pipeline after the spanner 303 is just stirred.

When the device clamps the pipeline, the adjustment and the setting are needed at first, and the specific setting method is as follows:

S1, according to the diameter of a pipeline, pressing the rotary adjusting knob 1 to enable the indication scales 204 of the two support square rods 202 to correspond to the diameter of the pipeline, then placing the device on the pipeline by taking the two support square rods 202 as supports, at the moment, enabling the wrench 303 to be in a tensioning and locking state, and then pressing the adjusting knob 1 on two sides of the rotary clamping mechanism to enable the clamping arms 302 to clamp the pipeline;

S2, the clamping force after the step S1 is very small, so that the wrench 303 is required to be in an open state again, the device is removed, the adjusting knobs 1 on two sides of the clamping mechanism are adjusted again, the clamping arms 302 are finely adjusted in the direction slightly smaller than the pipe diameter, the specific fine adjustment size is determined according to the actual clamping force, the clamping force is larger when the clamping setting pipe diameter is smaller than that of the clamped pipe, and meanwhile, the wrench 303 is required to be pushed by applying larger force during clamping, so that the wrench is adjusted to a proper amount according to actual conditions in actual use.

S3, after setting, the device is only required to be placed on a pipeline each time when the device is used, and then the spanner 303 is shifted to a locking position, so that the device is accurately clamped and positioned on the pipeline.

The utility model has been described in connection with the preferred embodiments, but the utility model is not limited to the embodiments disclosed above, but it is intended to cover various modifications, equivalent combinations according to the essence of the utility model.
