DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The principles and features of the present utility model are described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0020] This embodiment provides an automatic internal rotation and turning equipment for processing the shield machine propulsion cylinder. This device is used for automatic internal rotation and turning operations during the processing of the shield machine propulsion cylinder, improving the stability of the automatic internal rotation and turning of the shield machine propulsion cylinder and facilitating the processing of the shield machine propulsion cylinder.

[0021] Reference Figure 1 Figure 1 , an automatic internal rotation and turning equipment for the processing of shield machine propulsion cylinders, includes two fixed bottom plates 1. A turning mechanism 2 is jointly arranged on one side of the two fixed bottom plates 1 close to each other. A processing mechanism 3 is jointly arranged above the two fixed bottom plates 1. The processing mechanism 3 includes two sliding frames 303. The bottom surface of each sliding frame 303 is in contact with the upper surface of the fixed bottom plate 1. By using the two sliding frames 303, it is convenient to support and fix the structure for clamping and driving the cylinder to rotate, so as to facilitate the processing of the shield machine propulsion cylinder.

[0022] Reference Figure 1 And Figure 2 Figure 2 , the turning mechanism 2 includes a fixed platform 201. One side surface of the two fixed bottom plates 1 close to each other is fixedly connected to the outer surface of the fixed platform 201. A stepping motor 202 is fixedly connected to the inner wall of the fixed platform 201. The stepping motor 202 is an open-loop control motor that converts an electrical pulse signal into an angular displacement or a linear displacement. The model of the stepping motor 202 is PH533HG1-NA. The output end of the stepping motor 202 is fixedly connected to a rotating disk 203. One side surface of the two sliding frames 303 away from each other is fixedly connected to a hydraulic rod 302. The upper surface of each fixed bottom plate 1 is fixedly connected to a fixed baffle 301. One side surface of the two fixed baffles 301 close to each other is respectively fixedly connected to one end of the two hydraulic rods 302 away from each other. By using the fixed baffle 301, the hydraulic rod 302 can be fixed between the fixed baffle 301 and the sliding frame 303, so as to facilitate the use of the hydraulic rod 302 to push the sliding frame 303 to slide on the fixed bottom plate 1.

[0023] Reference Figure 1 、 Figure 2 And Figure 3 Figure 3 , the bottom surface of the rotating disk 203 is fixedly connected with sliding columns 204 arranged at equal distances. A stable sliding groove 205 is opened on the upper surface of the fixed platform 201. Each sliding column 204 is slidably connected to the inside of the stable sliding groove 205. The inner walls of the two sliding frames 303 are respectively fixedly connected with a limiting component 304 and a three-jaw chuck 305. A turning tool 306 is fixedly connected to the upper surface of one of the fixed bottom plates 1. By using the rotating motor and the limiting workpiece arranged by the limiting component 304, and through the three-jaw chuck 305, it is convenient to clamp and fix the cylinder, so as to facilitate driving the cylinder to rotate by the limiting component 304 and using the turning tool 306 to process it.

[0024] Reference Figure 1 And Figure 4, a positioning seat 206 is fixedly connected to the upper surface of the rotating disc 203. Two positioning rings 210 are slidably connected inside the positioning seat 206. An oil cylinder fixing ring 209 is fixedly connected to the inner wall of the positioning seat 206. Clamping assemblies 216 are fixedly connected to the inner walls of the oil cylinder fixing ring 209 and each positioning ring 210. By using the pushing hydraulic structure and universal bearings included in the clamping assembly 216, the oil cylinder can be stably clamped and fixed through the oil cylinder fixing ring 209 and the positioning ring 210, so that the oil cylinder can be stably and automatically rotated and turned inward.

[0025] Refer to Figure 1 and Figure 4 , two sliding blocks 211 are fixedly connected to the outer surface of each positioning ring 210. Two groups of sliding grooves 207 are formed on the upper surface of the positioning seat 206. Each group of sliding blocks 211 is slidably connected inside the sliding groove 207. Moving sliders 212 are fixedly connected to the mutually remote side surfaces of the two groups of sliding blocks 211. The bottom surface of each group of moving sliders 212 is in contact with the upper surface of the positioning seat 206. By using the moving sliders 212, it is convenient to fix the sliding blocks 211, thereby limiting and fixing the positioning rings 210.

[0026] Refer to Figure 1 and Figure 4 , a fastening bolt 213 is rotatably connected inside each group of moving sliders 212. Two groups of fastening sliding grooves 208 are formed on the upper surface of the positioning seat 206. Each group of fastening bolts 213 is slidably connected inside the fastening sliding groove 208. The bottom ends of the two groups of fastening bolts 213 respectively penetrate through the fastening sliding groove 208 and extend to both sides of the positioning seat 206. By sliding the fastening bolts 213 in the fastening sliding groove 208, the fastening bolts 213 are manually twisted to fix the moving sliders 212 on the positioning seat 206.

[0027] Refer to Figure 3 and Figure 4 , a tightening block 214 is threadedly connected to the outer surface of each group of fastening bolts 213. Two tightening grooves 215 are formed on both side surfaces of the positioning seat 206. Each group of tightening grooves 215 is communicated with the fastening sliding groove 208. Each group of tightening blocks 214 is slidably connected inside the tightening groove 215. By arranging the tightening blocks 214 in the tightening grooves 215, the tightening blocks 214 can only slide inside and cannot rotate, which is convenient for the tightening blocks 214 to squeeze the positioning seat 206, and can conveniently fix and limit the oil cylinder.

[0028] Working principle: When in use, first connect the stepping motor 202, the clamping assembly 216, the hydraulic rod 302 and the limiting assembly 304 to the power supply. When it is necessary to use this equipment to automatically internally rotate and process the shield machine propulsion cylinder, it is convenient to process both ends of the shield machine propulsion cylinder. First, place this equipment on the horizontal ground manually, so that the two fixed bottom plates 1 and the fixed table 201 are fixed at the required positions, so that this equipment can be stably used to process the shield machine propulsion cylinder. Then, manually control the hydraulic rod 302 to move the two sliding frames 303 away from each other, and place the cylinder into the cylinder fixing ring 209 and the two positioning rings 210. Clamp the cylinder by controlling the clamping assembly 216, and manually move the positioning ring 210 in the positioning seat 206 to sleave the positioning ring 210 at a suitable position outside the cylinder. Use the sliding block 211 to slide in the sliding groove 207 to improve the movement stability of the positioning ring 210. And manually twist the fastening bolt 213 sliding in the fastening chute 208, so that the tightening block 214 can be firmly clamped into the tightening groove 215 by the fastening bolt 213, so that the moving slider 212 can be firmly fixed on the positioning seat 206, and then the two positioning rings 210 can firmly fix the cylinder.

[0029] Control the two hydraulic rods 302 to move the two sliding frames 303 closer, and use the three-jaw chuck 305 to clamp the cylinder. Drive the cylinder to rotate by controlling the power supply of the limiting assembly 304, so that the turning tool 306 can be used to process the cylinder. When it is necessary to flip the cylinder, only need to control the hydraulic rod 302 to move the two sliding frames 303 away from each other, and control the stepping motor 202 to drive the rotating disk 203 to rotate. Since the upper surface of the rotating disk 203 is fixedly connected to the bottom surface of the positioning seat 206, the rotation of the rotating disk 203 can be used to drive the cylinder to rotate, and use the multiple sliding columns 204 to rotate in the stable chute 205 to improve the flipping stability of the cylinder and facilitate the processing of the cylinder.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
