After the thermal spraying treatment, the bonding force between the ball valve and the surface alloy coating can reach 70MPa, the porosity is lower than 1%, the HV hardness of the coating is higher than 1200, the sealing performance of the hard sealing ball valve can be obviously improved by the thermal spraying technology, and the service life of the ball valve is limitedly prolonged. However, in the spraying process, the ball valve is hollow in the spherical axial direction, so the spraying work is difficult to manufacture, the ball valves are various in types and need to be manufactured with a large number of tools, the machining unit is troublesome, the tool for manufacturing each type of ball valve cannot be universal with other types of ball valves, and the manufacturing of the special tool is time-consuming, labor-consuming, waste and large in capital.
The utility model has the following contents:
the utility model discloses the technical problem that will solve is: overcome prior art's not enough, provide a reasonable in design, improve work efficiency and be applicable to the ball valve spraying frock of multiple ball valve spraying from feeling relieved.
The technical scheme of the utility model is that:
the utility model provides a from ball valve spraying frock of centering, includes the fixed axle, half section in the left side of fixed axle is cylindrical structure, and half section in the right side is screw rod formula structure, and, the left end portion of fixed axle is provided with the centre gripping handle, and right-hand member portion is provided with the apex hole, be provided with fixed connector on the half section cylinder in the left side of fixed axle, be provided with on the half section screw in the right side of fixed axle and remove the connector, the two sliding type is connected, fixed connector and removal connector are articulated through support and arc kicking block respectively, the arc kicking block is two, are located respectively the both sides of fixed axle just, the outside of removing the connector is provided with lock nut.
A check ring is arranged at the left end of the fixed shaft close to the clamping handle, a bushing is arranged between the movable connector and the locking nut, and the bushing can slide on the screw rod.
Fixed connector and removal connector are U type structure, and the internal surface of arc kicking block also is provided with U type structure, and two liang of corresponding U type structures are equallyd divide and are do not connected through support and articulated shaft rotary type.
The utility model has the advantages that:
1. the utility model discloses the distance at two arc kicking blocks and lead screw center equals to the speed and the distance of the outside expansion of two arc kicking blocks also equal, so reached from the effect of centering.
2. The utility model discloses one end has and adds the handle and can use the chuck centre gripping, if the jack catch does not clutch the frock in the time, the retaining ring can prevent that the frock from leading to the frock to drop the damage to the motion of chuck direction at rotatory in-process.
3. The utility model discloses the lead screw afterbody has a center hole, can use top tight frock of deciding after the ball valve installation finishes, prevents to throw at rotatory in-process frock.
4. The utility model discloses be provided with the bush, can move the connector on the lead screw in the same direction as smooth promotion, with the lock nut cooperation, can be the fixed case inner wall of arc kicking block tensioning.
5. The utility model relates to a rationally, improve work efficiency and be applicable to multiple ball valve spraying, its application scope is wide, has good economic benefits after promoting.
Description of the drawings:
fig. 1 is a schematic structural view of a self-centering ball valve spraying tool.
The specific implementation mode is as follows:
example (b): referring to fig. 1, there are 1-grip handle, 2-retainer ring, 3-fixed connector, 4-bracket, 5-arc top block, 6-bush, 7-lock nut, 8-lead screw, 9-tip hole, 10-mobile connector, 11-articulated shaft, 12-fixed shaft.
From ball valve spraying frock of centering, including fixed axle 12, wherein: the left half section of fixed axle 12 is cylindrical structure, the right half section is screw rod formula structure, and, the left end portion of fixed axle 12 is provided with centre gripping handle 1, the right-hand member portion is provided with apex hole 9, be provided with fixed connector 3 on the left half section cylinder of fixed axle 12, be provided with on the right half section lead screw 8 of fixed axle 12 and remove connector 10, the two sliding type connection, fixed connector 3 and removal connector 10 are articulated with arc kicking block 5 through support 4 respectively, arc kicking block 5 is two, be located the both sides of fixed axle 12 respectively just, the outside of removing connector 10 is provided with lock nut 7.
The preferred scheme is as follows: the left end of the fixed shaft 12 is provided with a retainer ring 2 close to the clamping handle 1, a bushing 6 is arranged between the movable connector 10 and the locking nut 7, and the bushing 6 can slide on the screw rod 8. Fixed connector 3 and removal connector 10 are U type structure to the internal surface of arc kicking block 3 also is provided with U type structure, and two liang of corresponding U type structures are equallyd divide and are connected through support 4 and articulated shaft 11 rotary type respectively.
During operation, the clamping handle 1 can be clamped by a chuck, and if the clamping jaw does not tightly grasp the tool, the retainer ring 2 can prevent the tool from falling and being damaged due to the fact that the tool moves towards the chuck in the rotating process. 8 afterbody of lead screw has a centre hole 9, can use top tight frock after the ball valve installation finishes, prevent to throw at rotatory in-process frock, wear into the frock to the ball valve, make the hollow inner wall of ball valve correspond the contact with arc kicking block 3 together, extrude bush 6 through clockwise rotation lock nut 7, can make movable connector 10 move to the central point of ball valve puts, movable connector 10 can force support 4 at the in-process of inward movement and upwards arch up, and arc kicking block 3 is in the middle of two supports 4 tops, two supports 4 can make arc kicking block 3 outwards expand when encircleing up, thereby reach the effect that arc kicking block 3 and ball valve cavity inner wall closely cooperate. The distance of the outward expansion of the support 4 can be controlled by the locking nut 7, so that the diameter of the hollow inner wall of the ball valve can be used within the stroke range of the motion of the tool support, and the tool can adapt to various types of ball valves. The distance between the two arc-shaped jacking blocks 3 and the center of the screw rod 8 is equal, and the outward expansion speed and distance of the two arc-shaped jacking blocks 3 are also equal, so that the self-centering effect is achieved. After spraying, the locking nut 7 is rotated reversely, the two arc-shaped jacking blocks 3 shrink towards the screw rod 8, the ball valve can be taken out, and one working cycle is completed.
it should be understood that the above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent variations and modifications made to the above embodiments according to the technical spirit of the present invention are within the scope of the present invention.
