Description

[0002] Pressure vessels refer to closed equipment that contains gas or liquid and bears a certain pressure. Pressure vessels are widely used. They play an important role in many sectors such as industry, civil industry, military industry, and many fields of scientific research. Among them, the most used are in the chemical industry and petrochemical industry. The pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. At present, pressure vessels often involve welding and cutting in the production process. There are weld nodules and burrs on their outer surfaces, so they need to be polished by polishing equipment.

[0003] However, since the pressure vessel has a certain length and volume, multiple driving sources need to be set up to achieve comprehensive grinding, such as a driving source for driving the grinding wheel to rotate, a driving source for driving the grinding wheel to move, and even a driving source for driving the pressure vessel to move or rotate. Even if no driving source is set, manual adjustment is required to achieve the adjustment of the grinding position. Too many driving sources make the entire grinding equipment relatively tall and energy-intensive, and manual adjustment is time-consuming and labor-intensive, resulting in low grinding efficiency.

[0047] It should be noted that the device frame 1 is also provided with a hood for protecting the processing area. The hood can be opened and a transparent observation window is provided on it to facilitate observation of the internal processing conditions. At the same time, the device is also equipped with necessary means such as a control system and a power supply system, all of which adopt conventional technologies and will not be elaborated on in detail.

[0048] When in use, the pressure vessel body 6 is placed on the bracket 12 on the side of the second fixing frame 10 away from the first fixing frame 9, and initially, the end of the first clamping arm 7 away from the first positioning frame 3 is located inside the second rotating cylinder 24, and then the second clamping arm 8 is screwed, and the second clamping arm 8 is displaced to push the pressure vessel body 6 to move, and then one end of the pressure vessel body 6 enters the inside of the first rotating cylinder 18, and the first clamping arm 7 and the second clamping arm 8 The ends close to each other clamp the two ends of the pressure vessel body 6 respectively, and then during grinding, the control motor 11 drives the first end face gear ring 16 and the second end face gear ring 17 to rotate, and then the second rotating cylinder 24 and the first rotating cylinder 18 rotate. At this time, the grinding wheel 27 is not in contact with the pressure vessel body 6, and the gear 26 is not meshed with the gear ring 25. Therefore, initially, when the first rotating drum 18 drives the driving block 21 to rotate, it will touch the driving shaft 20, and then the driving block 21 is pressed to move toward the direction of the first fixed frame 9, the first spring 34 is compressed, and the driving block 21 drives the bearing seat 23 to move toward the axial direction of the first rotating drum 18 through the cooperation of the second rotating shaft 35 and the first guide groove 33. When the slot 36 and the block 37 are matched, the second spring 38 is reset, and one end of the block 37 is inserted into the slot 36. At this time, the grinding wheel 27 just contacts the outer wall of the pressure vessel body 6, and the gear 26 is meshed with the gear ring 25. Then, when the first drum 18 and the second drum 24 rotate, the gear 26 is driven to rotate due to the action of the gear ring 25, and then the grinding wheel 27 rotates. Since the first drum 18 rotates synchronously, the grinding wheel 27 rotates around the rotating surface tooling of the pressure vessel body 6, and then the grinding wheel 27 grinds the outer wall of the pressure vessel body 6. When the first drum 18 rotates one circle, the driving rod 30 enters a second guide groove 41 to drive the first roller 14 to rotate, and then the first roller 14 drives the second roller 42 to rotate through the synchronous belt 13, and the second roller 42 drives the force plate 45 to rotate. Since the number of the force plate 45 is less than the second guide groove 41, when When the first rotating drum 18 rotates for multiple turns, one of the force-applying plates 45 will come into contact with one of the force-bearing plates 44, and when they come into contact, the second positioning frame 4 and the first positioning frame 3 will be driven to move forward for a distance as a whole. The first rotating drum 18 rotates for multiple turns to drive the pressure vessel body 6 to move, which can ensure that the corresponding part of the outer side of the pressure vessel body 6 and the grinding wheel 27 can be fully ground, thereby changing the position of the pressure vessel body 6. In addition, the driving rod 30 drives the first roller shaft 14 to rotate once through the second guide groove 41, and then the second guide groove 41 will correspond to the driving rod 30, so that when the driving rod 30 rotates to the first roller shaft 14, it is convenient to drive the first roller shaft 14 to rotate again;

[0049] In addition, it should be noted that when the force-applying plate 45 is in a separated state from the force-bearing plate 44, the locking tooth 48 and the rack 43 are in a clamping state, and the first positioning frame 3 and the second positioning frame 4 remain stationary as a whole. Before the force-applying plate 45 touches the force-bearing plate 44, one end of the corresponding unlocking plate 46 will enter the third guide groove 50 through the first through groove 32, and then the two locking plates 47 will move closer to each other, and then the locking tooth 48 and the rack 43 will separate, and the second positioning frame 4 will be unlocked. Then the force-applying plate 45 will touch the force-bearing plate 44 and drive the second positioning frame 4 to move forward a certain distance. When the force-applying plate 45 is separated from the force-bearing plate 44, one end of the corresponding unlocking plate 46 will separate from the third guide groove 50, and then the third spring 49 will reset, and the locking plate 47 will drive the locking tooth 48 to clamp with the rack 43, and then the first positioning frame 3 and the second positioning frame 4 are fixed as a whole again, avoiding the instability of the pressure vessel body 6 during grinding;

[0050] After completion, the locking tooth 48 can be manually separated from the rack 43, and then the first positioning frame 3 and the second positioning frame 4 can be pushed to reset as a whole, and then the second clamping arm 8 is screwed to loosen the pressure vessel body 6, and the pressure vessel body 6 is removed, and finally the block 37 is pulled outward, one end of the block 37 is separated from the slot 36, the first spring 34 is reset, and the bearing seat 23 drives the gear 26 and the grinding wheel 27 to move away from the axis of the first rotating drum 18, waiting for subsequent grinding operations.

[0051] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
