Exemplarily, as shown in Figure 1 , supporting device 300 includes two parallel and spaced supporting seats, and the supporting surface of the supporting seat is a cylindrical surface. When mass production, supporting device 300 is used to support and position pressure vessel 100, the machining consistency of pressure vessel 100 is good, the working efficiency can be improved, and the interchangeability of pressure vessel 100 is ensured.

[0043] According to the actual production needs, marking device 200 can be arranged in the first direction of pressure vessel 100, for example, the first direction is the length direction of pressure vessel 100, and marking device 200 can mark at a certain position in the length direction of pressure vessel 100. Alternatively, marking device 200 is also arranged in the second direction of pressure vessel 100, and the second direction is perpendicular to the first direction;Exemplarily, as shown in Figure 1 , marking device 200 is arranged in the axial direction of pressure vessel 100 and the radial direction of pressure vessel 100, so that marking operation can be performed on the cylinder and the head of pressure vessel 100 respectively.

[0044] As shown in Figure 3 , Figure 4 , Figure 5 and Figure 6 , marking device 200 includes guiding mechanism 220 and numerical control operating mechanism 210, and guiding mechanism 220 guides the movement of numerical control operating mechanism 210.

[0045] The numerical control operating mechanism 210 comprises a sliding component platform 211, a laser receiver 213 and a scribing laser emitter 214. The sliding component platform 211 cooperates with the guide mechanism 220 to allow the sliding component platform 211 to move along a set direction; the laser receiver 213 and the scribing laser emitter 214 are fixed on the sliding component platform 211 and move synchronously with the sliding component platform 211. The laser receiver 213 and the scribing laser emitter 214 are fixed on the upper side of the sliding component platform 211, and can also be arranged on the side of the sliding component platform 211 facing the pressure container 100. In use, the scribing laser emitter 214 can not only cooperate with the laser receiver 213 to confirm the zero point position of the scribing laser emitter 214 relative to the pressure container 100, but also can adjust the power of the scribing laser emitter 214 to laser etch a mark line on the outer wall of the pressure container 100, so that the utilization rate of the scribing laser emitter 214 is high, and the structure of the equipment is simplified.

[0046] The guide mechanism 220 comprises a base 221, which is a frame structure combined and fixed as a whole by profiled materials such as square steel by welding or the like.

The sliding component platform 211 can be provided with a sliding block, which is connected with the linear guides 222 by sliding, and since the sliding block and the sliding component platform 211 can be disassembled, the later maintenance is facilitated. The number of the linear guides 222 can be selected as required, for example, the number of the linear guides 222 is 2, and the two linear guides 222 are arranged in parallel and at intervals. In actual use, the guide structure is not limited to the linear guides 222, and existing guide solutions such as guide columns and guide grooves can also be used.

[0047] Further, the guide mechanism 220 further comprises limit blocks 224 arranged at the ends of the linear guides 222 to limit the movement of the sliding component platform 211 and prevent the sliding component platform 211 from sliding off the linear guides 222. Preferably, the number of the limit blocks 224 is 2, which are respectively arranged at the two ends of the linear guides 222. The limit blocks 224 can be directly fixed on the base 221, or can be directly fixed on the linear guides 222 as required. When the number of the linear guides 222 is 2, the limit blocks 224 can be arranged in the area between the two linear guides 222 and fixed on the base 221.

[0048] The base 221 and the sliding component platform 211 are also provided with a driving structure to drive the sliding component platform 211 to move to a set position. As an embodiment of the driving structure, it comprises a servo motor 215 and a gear 217; the base 221 is fixed with a linear rack 223; the linear rack 223 is parallel to the linear guide rail 222. The servo motor 215 is fixed on a servo motor seat 216, which is fixed on the lower side of the sliding component platform 211, extending to the lower side of the sliding component platform 211, and its output shaft is fixedly connected with the gear 217; the gear 217 is engaged with the linear rack 223. The servo motor 215 drives the gear 217 to rotate; the gear 217 is engaged with the linear rack 223, and under the cooperation of the gear 217 and the linear rack 223, the linear motion of the sliding component platform 211 on the base 221 can be realized. In actual application, the driving structure is not limited to gear engagement transmission, and other driving schemes such as lead screw and belt can also be used.

[0049] Preferably, the linear rack 223 is fixed on the side of the base 221 away from the support device 300, and the side of the linear rack 223 provided with the transmission teeth is downward or vertically arranged, so that the tooth grooves between the transmission teeth do not accumulate sundries, dust and the like, ensuring the engagement transmission effect and precision. The laser receiver 213 and the line laser emitter 214 are located on the side of the sliding component platform 211 close to the support device 300.

[0050] Further, the sliding component platform 211 is also provided with a numerical control control panel 212, which is electrically connected with the laser receiver 213, the line laser emitter 214 and the servo motor 215; the numerical control control panel 212 can receive the signal of the laser receiver 213, and can also control the line laser emitter 214 and the servo motor 215. The electrical connection mode and control of the numerical control control panel 212 with the laser receiver 213, the line laser emitter 214 and the servo motor 215 are prior art, and no improvement is made in the present application. Preferably, the numerical control control panel 212 is located on the side of the sliding component platform 211 away from the support device 300, which is convenient for operation.

[0051] When the device is used, the pressure container 100 is placed on the supporting device 300. The starting moving position of the sliding component platform 211 avoids the pressure container 100 and is not directly opposite to the pressure container 100; the visible light beam can be emitted by the line laser emitter 214 by controlling the servo motor 215 to move the sliding component platform 211 in a set direction; when the laser emitted by the line laser emitter 214 meets the obstacle (i.e. the pressure container 100), the laser receiver 213 receives the light reflected by the laser, and the signal position is the zero position; then, the servo motor 215 is controlled to rotate according to the distance between the line marking position of the pressure container 100 and the zero position, so as to drive the sliding component platform 211 to continuously move to the set position; after reaching the position, the power of the line laser emitter 214 is controlled to be amplified, and the obvious line on the pressure container 100 is etched by the laser. In the process, the servo motor 215 accurately controls the rotation of the gear 217, and the linear rack 223 can accurately control the moving position of the line laser emitter 214, and the line marking mark can be etched on the workpiece produced by the line laser emitter 214, so that the accuracy of the line marking of the pressure container 100 can be effectively improved, and the consistency of the welding size of the pressure container 100 can be ensured.
