Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: referring to fig. 1 to 9, a clamp for spraying a target material includes a first end 2, a second end 4, a sheath 3, an inner tube 5 and a bolt 6. The one end of first end 2 is provided with flange 21 for be connected with target spraying equipment, the other end of first end 2 is provided with first end 22 that stretches, the both sides of first end 2 are provided with screw hole 27, the inside of first end 2 is provided with the inlet opening 26 that runs through its both ends, be provided with a plurality of apopores 24 around the inlet opening 26, first end 22 that stretches is provided with first concave station 25, first end 22 that stretches is provided with first seal groove 23 on the outer circumference. The one end of second end 4 is provided with apical pore 45, conveniently withholds with the top of circling round on the target spraying equipment tailstock, the other end of second end 4 is provided with the second and stretches into end 41, the both sides of second end 4 are provided with screw hole 27, the inside of second end 4 is provided with second concave station 42, the bottom of second concave station 42 is provided with second recess 46, the both sides of second concave station 42 are provided with first recess 43, second recess 46 and first recess 43 intercommunication, the second is stretched and is provided with second seal groove 44 on the outer circumference of end 41. The inner side of the sheath 3 is provided with a matching part 31, one side of the matching part 31 is provided with a protection part 32, the other side of the protection part 32 is provided with a blocking part 33, and the sheath 3 is provided with a through hole 34 penetrating through the inner side and the outer side of the sheath. The fitting portion 31 is for fitting with the outer circumference of the first head 2 or the second head 4; the inner diameter and length of the protector portion 32 are slightly larger than the outer diameter and length of the threaded port 11, respectively; the end surface of the stopper 33 is aligned with the inner side surface of the relief groove 12 after the installation is completed. The inner tube 5 is tubular and has bosses 51 at both ends, and the bosses 51 are adapted to be inserted into the first recess 25 or the second recess 42.

The cross sections of the first concave platform 25 and the second concave platform 42 are regular hexagons and have the same size, and the cross sections and the size of the boss 51 are the same as those of the first concave platform 25 and the second concave platform 42.

The first groove 43 has a rectangular parallelepiped shape.

The second groove 46 is cylindrical with a diameter close to the inner diameter of the inner tube 5.

The length of the inner tube 5 is greater than the length of the back tube 1 to facilitate installation.

The working principle and the process are as follows: referring to fig. 1-9, first, sealing rings are installed in the first sealing groove 23 and the second sealing groove 44, then the first extending end 22 is inserted into one end of the back tube 1, then the boss 51 at one end of the inner tube 5 is inserted into the first concave platform 25, because the length of the inner tube 5 is greater than that of the back tube 1, the other end of the inner tube is exposed from the other end of the back tube 1, the end is held by hand to be located on the axis of the back tube 1 as much as possible, then, as shown in fig. 2, the second concave platform 42 on the second end 4 is sleeved on the boss at the end of the inner tube 5, and then the second end 4 is continuously pushed to the right, so that the second extending end 41 is inserted into the back tube 1. The through holes 34 in the sheath 3 are then aligned with the threaded holes 27 and secured with the bolts 6, completing the assembly, as shown in fig. 9. The second recess 42 is deeper and the depth of the first recess 25 plus the second recess 42 plus the length of the back tube 1 is close to the length of the inner tube 5 minus the length of the first and second projecting ends 22 and 41, preferably less than 0.2 times the height of the projection 51. In order to prevent the first and second terminals 2 and 4 from falling off, the lengths of the first and second extending ends 22 and 41 should be longer than appropriate. The assembled components can be mounted on a rotating bed of the plasma spraying equipment, a water passing device is arranged on the rotating bed, a water outlet of the water passing device is connected with a water inlet 26, a water return port of the water passing device is communicated with a water outlet 24, the water passing device adopts a structure that two pipes are sleeved together, water is discharged from the inner pipe, water is returned from a cavity between the two pipes, and a flange is arranged at the end part of the outer pipe. The cooling water can enter the inner pipe 5 from the water inlet 26, then flow into the back pipe 1 from the second groove 46 and the first groove 43 and the gap between the second concave platform 42 and the outside of the inner pipe 5, and finally flow out from the water outlet hole 24, so as to cool the back pipe 1. Because the cross sections of the boss 51, the first concave table 25 and the second concave table 42 are regular hexagons, when the rotating bed drives the first end 2 to rotate, the inner tube 5 can drive the second end 4 to rotate synchronously, so as to drive the back tube 1 to rotate, and compared with a structure with only one end to drive, the structure has the advantages that the back tube 1 is not subjected to torsion and is not easy to slip. The blocking portion 33 blocks most of the chrome material, but since the flame flow of the spraying is diffused outward, a small amount of chrome enters the relief groove 12, and the protection portion 32 protects the screw port 11 from the chrome material spraying on the screw port 11.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
