[0037] The fixed assembly 8 comprises a fastening cone 801 rotatably mounted on the inner wall of the fixed hole plate 7. The inner hole structure of the fastening cone 801 is composed of two parts. The main body part is a straight wall circular hole, and one end is connected with a tapered hole with an enlarged diameter. The diffusion tapered hole of the fastening cone 801 can conveniently straighten the rod shell 1102 to better enter the fastening cone 801, avoiding the problem that the straightening rod shell 1102 is hindered during use. The arc head circular rod structure of the straightening rod shell 1102 can ensure that the whole enters the telescopic oil cylinder more smoothly. The surface of the fastening cone 801 is fixedly installed with a transmission gear ring 802 on the side close to the protective cover 5.

[0041] The connecting machine 3 comprises a guide inclined plate 301 arranged on one side of the outer wall straightening machine 13, and the height of the guide inclined plate 301 is arranged at the same height as the outer wall straightening machine 13, and one side of the guide inclined plate 301 is provided with a guide pipe frame 302, a rotating connecting rod 3021 is rotatably arranged inside the guide pipe frame 302 and close to one side of a storage groove frame 303, a pipe pushing rod 3022 is fixedly arranged on the rod wall of the rotating connecting rod 3021, and a pushing electric telescopic rod 3023 for pushing is arranged at the center of the rod wall of the rotating connecting rod 3021, the fixed end of the pushing electric telescopic rod 3023 is connected with the surface of the storage groove frame 303, and the pushing effect of the pushing electric telescopic rod 3023 can avoid the manual carrying work of the operator, one side of the guide pipe frame 302 is provided with the storage groove frame 303, one side of the storage groove frame 303 away from the fixed hole plate 7 is provided with a pushing table 304, the top surface of the pushing table 304 is embedded with an electric sliding rail 305, the top surface of the electric sliding rail 305 is fixedly provided with a pushing rod 306, the surface of the pushing rod 306 is slidably connected with the inner wall of the storage groove frame 303, one side of the storage groove frame 303 close to the fixed hole plate 7 is provided with a conveying table 307, and the top surface of the conveying table 307 is fixedly provided with a plurality of inclined chute blocks 308, and the inner wall of the plurality of inclined chute blocks 308 is on the same horizontal line as the inner wall of the storage groove frame 303.

[0042] The working principle of the above embodiment is as follows:

[0043] When the telescopic oil cylinder is used, the telescopic oil cylinder is straightened by the outer wall straightening machine 13, so that the straightening effect of the outer wall straightening machine 13 can be guaranteed, and the straightening effect of the outer wall straightening machine 13 on the telescopic oil cylinder is a mature technology, which will not be described in detail herein.

[0044] When the outer wall straightening machine 13 finishes straightening, the telescopic oil cylinder is conveyed to the guide inclined plate 301, and the inclined effect of the guide inclined plate 301 makes the straightened telescopic oil cylinder conveyed to the storage groove frame 303 through the guide pipe frame 302, then the telescopic oil cylinder is flipped and pushed into the storage groove frame 303 by the pipe pushing rod 3022 driven by the pushing electric telescopic rod 3023, and then the telescopic oil cylinder is conveyed to the inner wall of the fastening cone cylinder 801 by the pushing rod 306 driven by the electric sliding rail 305 through the inclined chute block 308.

[0045] After the operator uses the fastening bolt 805 to fix the straightened telescopic oil cylinder barrel of the outer wall, it is convenient to straighten the inner wall of the cylinder barrel. In the process of straightening the inside of the telescopic oil cylinder, the mounting block 1101 is moved to the inside of the telescopic oil cylinder, so that the straightening rod shell 1102 smoothly enters the inside of the telescopic oil cylinder through the enlarged opening at the upper end of the fastening cone barrel 801. The fastening cone barrel 801 of the present application is provided with an embedded groove structure at the connection position with the telescopic oil cylinder, which can ensure that the inner wall of the telescopic oil cylinder coincides with the inner wall of the fastening cone barrel 801, so that the straightening rod shell 1102 can more smoothly enter the telescopic oil cylinder. When the straightening rod shell 1102 extends into the telescopic oil cylinder, its inner wall will be in contact with the plurality of extrusion oval rollers 1202. Thus, under the extrusion contact of the plurality of extrusion oval rollers 1202, the inside of the telescopic oil cylinder can be supported and straightened. The extrusion oval rollers 1202 are inclined, which can drive the straightening rod shell 1102 to rotate during the rotation of the telescopic oil cylinder, thereby better ensuring the straightening effect of the inner wall of the telescopic oil cylinder. The rotation effect of the telescopic oil cylinder is achieved by the output motor 803 driving the connecting gear 804 and other structures. During the straightening process of the straightening rod shell 1102, the extrusion oval roller 1202 drives the transmission rod 1206 in the transmission rubber wheel 1207 to rotate. Because the transmission rubber wheel 1207 is closely attached to the extrusion oval roller 1202, the friction generated between the transmission rubber wheel 1207 and the extrusion oval roller 1202 can ensure the smooth rotation of the transmission rod 1206.

[0046] The transmission rod 1206 can ensure the movement of the two extrusion pieces 1209 in the square barrel 1203 through the convex extrusion effect of the cam block 1208. Then, under the movement of the extrusion pieces 1209, the sponge block lubricating liquid in the square barrel 1203 can be extruded. The storage box 6 is pre-filled with lubricating liquid, and the liquid pipe 1106 delivers the lubricating liquid to the sponge block in the straightening rod shell 1102. The lubricating liquid in the sponge block is conducted through the cotton bar 1205, so that the sponge block in the square barrel 1203 is also filled with lubricating liquid. The sponge fully filled with lubricating liquid is in contact with the extrusion oval roller 1202, which can avoid damage to the inside of the telescopic oil cylinder during the straightening of the extrusion oval roller 1202 and the inside of the telescopic oil cylinder. The present device can ensure the straightening of the inside and outside of the telescopic oil cylinder, and increase the use performance of the device. The present application is mainly aimed at straightening the cylinder barrel made of high-quality aluminum alloy plate, and the outer wall straightening machine 13 and the inner wall straightening machine 2 in the application can stamp the inner and outer surfaces of the cylinder barrel, thereby ensuring the stamping effect of the metal, and straightening the cylinder barrel by stamping.

[0047] The mounting mode, the connecting mode or the setting mode disclosed in the embodiment are all common mechanical connecting modes, and can be implemented as long as the beneficial effects can be achieved. In addition, the electrical components appearing in the embodiment are electrically connected with the master controller and the power supply. The master controller can be a conventional known device such as a computer which plays a control role. A person skilled in the art can realize the control of the electrical components through simple programming. The existing disclosed power connection technology also belongs to the common knowledge in the field. Therefore, the specific structure composition and working principle of the embodiment will not be described in more details.
