The second limiting member is used to connect the connecting portion and the fixing member. The supporting base plate has a triangular structure when viewed from above. This structure is only suitable for placing flat parts on it and is not convenient for impregnating tubular parts such as carbon-carbon cylindrical hot press molds, as they are prone to rolling off. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a special impregnation fixture for liquid phase densification using a carbon-carbon cylindrical hot press mold. During use, the pipe fitting is placed below the device, the cylinder is activated, causing three rotating clamping plates to rotate inwards, resulting in three arc-shaped clamping blocks holding the central pipe fitting. The upper part of the mounting plate is fixed to the winding machine via a hanging rope, allowing the hanging rope to be retracted and extended to move the device up and down. The device is then lowered so that the pipe fitting can be operated within the densification impregnation tank. This convenient fixture addresses the shortcomings of the existing technology by providing a special impregnation fixture for liquid phase densification using a carbon-carbon cylindrical hot press mold.

[0004] The objective of this utility model is achieved through the following technical solution:

[0008] 1. In this utility model, the middle sleeve of the clamping plate is connected to the symmetrical mounting sleeve side ears through the No. 2 rotating shaft, so that the upper part of the rotating clamping plate is connected to the middle mounting sleeve shaft, allowing the rotating clamping plate to rotate. The mounting hanging plate is connected to the middle mounting sleeve. The vertical slide rod is installed and fixed on the mounting hanging plate. The vertical slide rod is inserted into the slide rod insertion hole. The tapered slider is laterally positioned by the three vertical slide rods, preventing the tapered slider from moving laterally in the liquid phase densification of the carbon-carbon cylindrical hot press mold, ensuring that the tapered slider can only slide up and down. The limiting slide rod is inserted into the strip limiting groove. The tapered slider slides up and down to control the upper part of the clamping plate to slide in the strip limiting groove. Since the tapered slider has a tapered structure, the up and down movement of the tapered slider drives the rotating clamping plate to rotate axially, so that the three rotating clamping plates rotate centripetally or outward.

[0009] 2. The cylinder of this utility model is installed and fixed on the mounting plate. The piston rod is connected to the conical slider. When the cylinder works, it drives the conical slider to slide up and down, thereby controlling the three rotating clamping plates to rotate simultaneously. The side sleeve of the clamping block is connected to the symmetrical lower ears of the clamping plate through the No. 1 rotating shaft, so that the arc-shaped clamping block is installed below the rotating clamping plate and can rotate. In use, the pipe is placed under the device, the cylinder is started, and the three rotating clamping plates rotate inward so that the three arc-shaped clamping blocks clamp the middle pipe. The upper part of the mounting plate is fixed to the winding machine with the hanging rope. The hanging rope can be wound up and down to move the device up and down. The device is lowered so that the pipe can be operated in the dense impregnation tank. It is convenient to use. Attached Figure Description
