As shown in fig. 3, which is a schematic structural diagram of the clamping member 9, the clamping member 9 includes a chuck 2 and four jaws 3, the four jaws 3 are uniformly distributed on the chuck 2, and each jaw 3 is slidably connected to the chuck 2; locking and positioning screws 4 are arranged at the positions, corresponding to the clamping jaws 3, on the side of the chuck 2, the locking and positioning screws 4 are connected with the clamping jaws 3 in a matched mode, and the number of the clamping jaws 3 is at least 3 according to the use requirement; the chuck 2 is provided with a plurality of sliding grooves 10, the number of the sliding grooves 10 is consistent with that of the clamping jaws 3, and the bottoms of the clamping jaws 3 are provided with sliding blocks 11 which are in fit connection with the sliding grooves 10; the locking and positioning screw rod 4 is threaded in a sliding groove 10 on the chuck 2, and the end part of the locking and positioning screw rod 4 is connected with a sliding block 11 at the bottom of the clamping jaw 3 in a matching way; the sliding groove 10 is of an inverted T shape, and the shape of the sliding block 11 at the bottom of the jaw 3 is consistent with that of the inverted T-shaped sliding groove 10, specifically, as shown in a schematic structural diagram of the jaw 3 in fig. 4.
As shown in fig. 2, which is an enlarged schematic structural diagram of the plugging joint 6, the connection end of the plugging joint 6 and the opening of the gas cylinder 5 is provided with an external thread, the inner side of the opening of the gas cylinder 5 is provided with an internal thread matched with the external thread, and the opening of the gas cylinder 5 is matched with the internal thread and the external thread of the plugging joint 6 to play a role in connection and sealing; the end, connected with the tip 7, of the plugging joint 6 is provided with a mounting groove 13, a rolling bearing 14 is arranged in the mounting groove 13, the end of the tip 7 is arranged in the mounting groove 13 and is matched and fixedly connected with the rolling bearing 14, and a positioning jackscrew 12 used for fixing the rolling bearing 14 in the mounting groove 13 is arranged on the side of the plugging joint 6. The plugging connector 6 is made of an HPb59-1 type brass material, and the purpose of using the type brass is as follows: because steel gas cylinder 5 is at the polishing in-process, corrosion and tiny granule under the cutting can block up threaded connection department gap at the inside diffusion of gas cylinder 5, if shutoff joint 6 uses the steel material to make, so the external screw thread of its steel and 5 bottleneck steel screw-thread fit connection departments of gas cylinder can take place to bite the dead state, very easily produce the destruction to 5 bottleneck screw threads of gas cylinder after the dismantlement, lead to whole gas cylinder 5 to scrap. Therefore, the plugging connector 6 is made of brass which is softer than the steel gas cylinder 5, so that the thread of the opening of the gas cylinder 5 cannot be damaged after the plugging connector 6 is detached.
As shown in fig. 2, a rolling bearing 14 is arranged at the connecting end of the plugging joint 6 and the tip 7, and can play a role in protecting the screw thread at the connecting part of the plugging joint 6 and the opening of the gas cylinder 5. Specifically, during the rotation of the gas cylinder 5, if the thread at the connection part of the sealing joint 6 and the opening of the gas cylinder 5 is loosened, a force which is perpendicular to the axial direction and outward towards the end part of the tip 7 is generated; because the centre 7 is axially fixed, an opposite acting force is generated and faces the direction of the gas cylinder 5, and the gas cylinder 5 is scrapped because the rotating speed is high and the acting force cannot be released, the thread is damaged by displacement at the thread matching connection part. When the rolling bearing 14 is installed, the plugging joint 6 and the gas cylinder 5 can easily rotate around the end part of the tip 7, and the phenomenon of loosening of threads is reduced or avoided. In summary, the plugging joint 6 provided with the rolling bearing 14 has the following characteristics: not only has good sealing effect, but also ensures that the gas cylinder 5 is safer and more stable in the rotating process; the tip 7 can enable the plugging joint 6 used at the opening of the gas cylinder 5 to be sealed on the opening of the gas cylinder 5 more tightly, the grinding and rust removing process is in a completely sealed state, and the influence of dust leakage on the environment is avoided.
The utility model relates to a gas cylinder 5 grinding steps of gas cylinder internal surface clearance rust cleaning equipment as follows: (1) firstly, injecting grinding and shot blasting into a gas cylinder from the opening of the gas cylinder 5, wherein the injection amount is about one third of the internal volume of the whole gas cylinder 5, and sealing the opening by using a plugging joint 6; (2) then, horizontally hoisting the gas cylinder 5 by a crane and installing the gas cylinder on a clamping piece 9 of the lathe 1, clamping the tail end of the gas cylinder 5 at a proper position by a clamping jaw 3 of the clamping piece 9, correspondingly adjusting a locking positioning screw rod 4 to lock the clamping jaw 3 to fix the tail end of the gas cylinder 5, and simultaneously butting and fixing a rolling bearing 14 of a plugging joint 6 with a tip 7; (3) after the fixed installation is finished, setting the rotating speed of a power output shaft of the lathe 1 to be 80r/min, starting the lathe 1, driving the power output shaft of the lathe 1 to drive the gas cylinder 5 clamped on the clamping piece 9 to rotate, and grinding the inner surface of the gas cylinder 5 by grinding and shot blasting additionally arranged in the gas cylinder 5 for 15-20 minutes.
The utility model relates to a 5 grinding theory of operation of gas cylinder internal surface clearance rust cleaning equipment: by means of the lathe 1, relative motion is generated between the grinding shot blast and the inner surface of the gas cylinder 5, a certain pressure is applied through centripetal force, the rust layer is removed from the inner surface of the gas cylinder 5, meanwhile, a high surface finish is obtained, and the method is very suitable for the gas cylinder 5 product due to the fact that the requirement on the inner surface appearance quality is high. When lathe 1 was rotatory, 5 inside grinding of gas cylinder throw the ball will even dispersion and open, and the grinding of using throws the hardness of ball material and is less than 5 material hardness of gas cylinder, when grinding and throw the ball and do relative motion with gas cylinder 5 under the exogenic action, has sharp-pointed edges and corners and high rigidity's granule in grinding and throwing the ball, can produce the cutting action on 5 internal surfaces of gas cylinder for a bit, then roll or slide and produce the smooth friction between 5 internal surfaces of gas cylinder for a bit. These particles are regarded as cutting blades, and produce a slight amount of cutting action on the inner surface of the gas cylinder 5, and cut off a layer of extremely thin metal from the inner surface of the gas cylinder 5 uniformly, namely, produce good cleaning effect on rust attached to the inner surface of the gas cylinder 5. In conclusion, the grinding shot blast additionally arranged in the gas cylinder 5 rotates along with the lathe 1 through mechanical movement of rotating at a certain speed, so that the grinding shot blast is in contact with the inner surface of the gas cylinder 5, and the effect of cleaning and removing rust is achieved.
