[0025] Specifically, the shaft holder 31 includes a base plate 311 and a cover plate 312. The cover plate 312 cooperates with the base plate 311 to conveniently fix the detection shaft 32, and a digital micrometer detection component is installed on the detection shaft 32. When the detection component rolls around the inner wall of the tank body 1, the roundness and coaxiality of the inner wall of the tank body 1 can be detected according to the sensor, which is relatively convenient. After loosening the locking screw, the detection shaft 32 can be removed, and disassembly and assembly are also relatively convenient.

[0026] Reference Figure 3 , Figure 5As shown, an extrusion sleeve 313 is also mounted on the detection shaft 32 close to the shaft holder 31, a front end pressure plate 314 is mounted on the extrusion sleeve 313 through a ball bearing, and an adjusting nut 315 is rotatably mounted on the back of the extrusion sleeve 313, the adjusting nut 315 is threadedly mounted on the detection shaft 32, the rear end holder 33 includes a baffle 331 mounted on the support seat 3, an extrusion bolt 332 is threadedly mounted on the baffle 331, and the rear end pressure plate 333 is rotatably mounted on the end of the extrusion bolt 332;

[0027] Specifically, in order to prevent the tank body 1 from shaking and affecting the detection result during the detection process, an extrusion sleeve 313 is installed on the detection shaft 32 close to the shaft holder 31, and an adjusting nut 315 is installed on the back of the extrusion sleeve 313. When the adjusting nut 315 is rotated, the extrusion sleeve 313 can be pushed to slide along the detection shaft 32 through the threaded cooperation of the adjusting nut 315 and the detection shaft 32, and the extrusion sleeve 313 can push the front end pressure plate 314 to be tightly against the front end of the tank body 1, and then the extrusion bolt 332 is rotated, and the threaded cooperation of the extrusion bolt 332 and the baffle 331 can push the rear end pressure plate 333 to be tightly against the rear end of the tank body 1, and the tank body 1 can be squeezed and fixed through the cooperation of the front end pressure plate 314 and the rear end pressure plate 333.

[0028] Reference Figure 1 , Figure 2 , Figure 4 As shown, a bidirectional screw 23 is also installed in the cylinder support frame 2, and the threads at both ends of the bidirectional screw 23 are symmetrically arranged about the center point, and a slide seat 22 is connected to the bottom of the support wedge 21, and the slide seat 22 is threadedly fitted on the bidirectional screw 23. A control motor 24 is also installed at the end of the cylinder support frame 2, and the output shaft of the control motor 24 is connected to the bidirectional screw 23;

[0029] Specifically, in order to keep the tank body 1 centered and stable when placed, the support wedge 21 arranged on the tube support frame 2 can support the tank body 1. When the control motor 24 is started, the bidirectional screw 23 can be rotated. Through the threaded cooperation between the bidirectional screw 23 and the slide seat 22, the two support wedges 21 can be pushed to slide synchronously, so that the support wedges 21 are always symmetrical about the center point of the tube support frame 2, and the inclined surface on the support wedge 21 will decompose the vertical force of the tank body 1, keep the tank body 1 in the middle of the support wedge 21, and ensure that the tank body 1 is centered.

[0030] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] The implementation principle of the roundness and coaxiality detection tooling of the distillation kettle body of the present application is:

[0033] When in use, the tank body 1 can be placed on the two cylinder support frames 2 first, and then the control motor 24 is started. By controlling the motor 24, the bidirectional screw rod 23 can be rotated. Since the threads on both ends of the bidirectional screw rod 23 are symmetrically arranged about the center point, when the bidirectional screw rod 23 rotates, the corresponding two supporting wedge blocks 21 can be pushed to slide synchronously by cooperating with the threads of the slide seat 22, so that the two supporting wedge blocks 21 are always kept symmetrical about the center point of the cylinder support frame 2. At this time, since the inclined surface of the supporting wedge block 21 can decompose the vertical downward force of the tank body 1, the tank body 1 receives the relative thrusts on both sides and remains in the middle of the supporting wedge block 21 to ensure that the tank body 1 is centered. In addition, when the bidirectional screw rod 23 continues to be rotated, the two supporting wedge blocks 21 can be pushed closer, thereby changing the contact position between the tank body 1 and the surface of the supporting wedge block 21, raising the tank body 1, and conveniently adjusting the tank body 1 so that the central axis of the tank body 1 coincides with the central axis of the detection axis 32, which is convenient for detection;

[0034] Then the detection shaft 32 can be installed on the shaft holder 31. The detection shaft 32 can be fixed by the cooperation of the cover plate 312 and the bottom plate 311. When the digital display micrometer detection component on the detection shaft 32 rolls around the inside of the tank body 1, the roundness and coaxiality of the inner wall of the tank body 1 can be monitored, which is more convenient.

[0035] In order to prevent the shaking of the tank body 1 during the detection process from affecting the detection result, an extrusion sleeve 313 is installed on the detection shaft 32 close to the shaft holder 31, and an adjusting nut 315 is installed on the back of the extrusion sleeve 313. When the adjusting nut 315 is rotated, the extrusion sleeve 313 can be pushed to slide along the detection shaft 32 through the threaded cooperation of the adjusting nut 315 and the detection shaft 32, and the extrusion sleeve 313 can push the front end pressure plate 314 to be tightly against the front end of the tank body 1. Then, the extrusion bolt 332 is rotated, and the threaded cooperation of the extrusion bolt 332 and the baffle 331 can push the rear end pressure plate 333 to be tightly against the rear end of the tank body 1. Through the cooperation of the front end pressure plate 314 and the rear end pressure plate 333, the tank body 1 can be squeezed and fixed to ensure the accuracy of the detection result.
