Description

Technical Field

[0001] The utility model relates to a heating tool for expanding the pipe of a compressor cylinder body, belonging to the field of heating tools for expanding the pipe of a cylinder body. Background Technique

[0002] An expanding pipe tool is a tool used to expand the inner and outer diameters of pipe fittings to expand the pipe end. A heating tool is used during pipe expansion to prevent damage to the cylinder body caused by directly expanding the cylinder opening. Therefore, it is necessary to insert a fitting into the cylinder end, and utilize the elastic recovery of the pipe fitting around the fitting to tightly connect the pipe fitting and the fitting, so as to make a pipe installation tool that does not leak water or air and can withstand a certain pressure.

[0003] In the prior art, a heating tool is used during the expansion of the compressor cylinder body. The heating tool for expanding the compressor cylinder body is composed of a fixture, a rotating rod, an expanding cone, and an electric heating tube. Therefore, when using the heating tool for expanding the compressor cylinder body, it is necessary to preheat the position of the expanding cone through a heating component, and then correspond the position of the expanding cone and the cylinder body through the fixture. At this time, rotate the rotating rod to move the position of the expanding cone, so that the expanding cone penetrates into the cylinder body to complete the expansion of the cylinder body. However, since the position where the electric heating tube heats the expanding cone is fixed, due to the limited position where the heating tube heats the expanding cone, the position where the expanding cone penetrates into the cylinder body will be affected, resulting in a temperature drop, which will cause the expanding cone to get stuck inside the cylinder body and the expanding cone cannot be taken out. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a heating tool for expanding the pipe of a compressor cylinder body to solve the problems raised in the above background technique. The utility model can make the heating component move together with the expanding cone to prevent the preheated expanding cone from being inside the cylinder body.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical scheme: A heating tool for expanding the pipe of a compressor cylinder body includes a housing, a side plate is fixedly connected to the surface of the housing, and a bottom plate is fixedly connected to the bottom of the side plate;

[0006] A first cylinder is fixedly connected to the center of the inner wall of the housing. A side groove is opened on the surface of the first cylinder, a first wall groove is opened in the center of the side groove, a round block is fixedly connected to the inner wall of the first wall groove, a second cylinder is fixedly connected to the top of the round block, a second wall groove is opened in the center of the second cylinder, a bottom block is movably connected to the round block, an electric heating tube is fixedly arranged on the top of the bottom block, a hot plate is fixedly connected to the surface of the electric heating tube, a card slot is opened in the hot plate, a cone block is fixedly connected to the top of the hot plate, a connecting block is fixedly connected to the bottom of the bottom block, and an electric telescopic rod is fixedly connected to the bottom of the connecting block.

[0007] Further, the bottom of the first cylinder contacts the outer shell. The shape of the round block fits the first wall groove. A groove is provided at the position where the round block contacts the bottom block. The shape of the central groove of the round block matches the shape of the bottom block, and four side grooves are equally spaced on the surface of the first cylinder.

[0008] Further, the hot plate is arranged inside the second wall groove. The shape of the hot plate fits the shape of the second wall groove. The position of the electric heating tube is covered by the card slot, and the position where the connecting block contacts the electric telescopic rod is penetrated by the electric telescopic rod and contacts the bottom end of the bottom block.

[0009] Further, a bottom groove is provided at the center of the bottom plate. A round plate is fixedly connected to the center of the bottom groove. A clamping plate is fixedly connected to the surface of the round plate. A shaft block is rotatably connected to the bottom of the round plate. A rotating block is rotatably connected to the center of the bottom of the shaft block. A connecting rod is fixedly connected to the surface of the rotating block. A pull rod is fixedly connected to the bottom of the connecting rod. A receiving plate is fixedly connected to the bottom of the bottom plate. A fixing plate is fixedly connected to the surface of the receiving plate.

[0010] Further, three clamping plates are equally spaced on the surface of the round plate. The tops of the three clamping plates are fixedly connected to the bottom of the first cylinder at the same time. The rotating block passes through the centers of the round plate, the receiving block and the shaft block and contacts the electric telescopic rod.

[0011] Further, six fixing plates are equally spaced on the surface of the receiving plate. Each receiving plate is connected to the surface of the fixing plate and the bottom of the bottom plate at the same time. A groove is provided at the center of the receiving plate.

[0012] Advantages of the utility model: First, it is necessary to align the position of the first cylinder with the opening of the cylinder body, start the electric heating tube and the electric telescopic rod. The electric telescopic rod pushes the position of the bottom block to move. At the same time, the bottom block moves along the inner wall of the second wall groove. The cone block and the hot plate are disengaged from the top of the second wall groove and contact the opening of the cylinder body. Since the electric heating tube heats the hot plate and the cone block, the cone block can enter the inside of the cylinder body from the opening of the cylinder body. In this way, the tube expansion of the cylinder body can be achieved, and the electric heating tube can move along with the flaring cone, completing the problem of preventing the flaring cone from being stuck inside the cylinder body due to temperature reduction;

[0013] Secondly, when the cone block enters the opening of the cylinder body, it is necessary to rotate the pull rod. The pull rod drives the rotating block connected by the connecting rod to rotate. The rotating block drives the shaft block, the receiving block and the electric telescopic rod to rotate. The electric telescopic rod drives the bottom block, the hot plate and the cone block to rotate, making it more convenient for the cone block to enter the inside of the cylinder body.
