As shown in fig. 1 to 5, an embodiment of the present application provides a processing device for a ball of a ball valve, which includes a chassis 1, a first support 2, a second support 3, and a hemispherical body 4. The first support 2 and the second support 3 are both of an L-shaped structure. The short sides of the first support 2 and the second support 3 are provided with first fixing holes. The working surface of the chassis 1 is provided with a plurality of second fixing holes corresponding to the first fixing holes along the two ends of the diameter of the working surface towards the center of the circle at intervals. The first support 2 and the second support 3 are respectively positioned at two ends of the diameter of the chassis 1. The first and second fixing holes fix the first and second supports 2 and 3 to the chassis 1 by bolts. The hemisphere 4 is fixed between the first support 2 and the second support 3 and the convex surface of the hemisphere 4 faces away from the chassis 1. The chassis 1 is detachably connected with the connecting end of the machine tool.
It should be noted that, in the embodiment of the application, the processing assembly of part of the ball valve sphere is assembled on the chassis 1 to form the processing device of the ball valve sphere; the chassis 1 of the ball valve sphere machining device is detachably connected with the machine tool connecting end, so that the technical purpose that a machine tool of one type can be matched with ball valve sphere machining components of different types is achieved, the problem that a machine tool of one type can only machine ball valve spheres of a certain range of size in the prior art is solved, and then the machine tool of one type can machine ball valve spheres of a plurality of range sizes. Because the distance between the first support 2 and the second support 3 can be adjusted through the second fixing hole, the ball valve ball processing device can also process ball valve balls with different sizes.
As shown in fig. 1, in the processing device for a ball of a ball valve provided by the embodiment of the application, a chute 11 is arranged on one side of a chassis 1, which is far away from a machine tool connection end, and is positioned at a distribution position of second fixing holes.
The chute 11 is provided to facilitate adjustment of the distance between the first support 2 and the second support 3, and the structure is simple.
As shown in fig. 1, 6 and 7, the processing device for a ball valve sphere provided by the embodiment of the application further comprises an upper mandrel 5 and a lower mandrel 6. The long sides of the first support 2 and the long sides of the second support 3 are provided with first connection holes. The side wall of the hemisphere 4 is provided with two second connecting holes. The upper core shaft 5 passes through the first connecting hole of the first support 2 and one of the second connecting holes to fixedly connect the first support 2 with the hemispherical body 4. The lower core shaft 6 passes through the first connecting hole of the second support 3 and the other second connecting hole to fixedly connect the second support 3 with the hemispherical body 4.
It should be noted that, in the embodiment of the present application, after the upper mandrel 5 and the lower mandrel 6 are connected with the hemispherical body 4, the convex surface of the hemispherical body 4 is processed, and the hemispherical body 4 is finally connected with the upper mandrel 5 and the lower mandrel 6 for cooperation, so that the convex surface of the hemispherical body 4 is convenient to process. The outer circle of the upper mandrel 5 is in clearance fit connection with one of the second connecting holes of the hemispherical body 4, and the outer circle of the lower mandrel 6 is in clearance fit connection with the other second connecting hole of the hemispherical body 4, so that the integrity of the hemispherical body 4 and other components of the ball valve ball processing device is improved; because the hemispheroids 4 are different in shape and irregular, the clamping tool is difficult to clamp the hemispheroids 4, and in the embodiment of the application, the upper mandrel 5 passes through the first connecting hole of the first support 2 and one of the second connecting holes to fixedly connect the first support 2 with the hemispheroids 4, and the lower mandrel 6 passes through the first connecting hole of the second support 3 and the other second connecting hole to fixedly connect the second support 3 with the hemispheroids 4. Therefore, the processing device of the ball valve ball body cannot cause difficulty in clamping the hemispheroids 4 because the hemispheroids 4 are different in shape and irregular.
As shown in fig. 1 and 10, in the processing device for a ball of a ball valve provided by the embodiment of the application, a first gasket 10 attached to the inner wall of the hemispherical body 4 is arranged at a position of the hemispherical body 4 close to a second connecting hole of the upper mandrel 5. A second gasket 12 attached to the inner wall of the hemisphere 4 is arranged at the position of the hemisphere 4 close to the second connecting hole of the lower mandrel 6.
In the embodiment of the present application, a first gasket 10 that is attached to the inner wall of the hemisphere 4 is disposed at a position of the hemisphere 4 near the second connecting hole of the upper mandrel 5, and a second gasket 12 that is attached to the inner wall of the hemisphere 4 is disposed at a position of the hemisphere 4 near the second connecting hole of the lower mandrel 6. The first gasket 10 and the second gasket 12 are used for protecting the inner wall of the hemisphere 4 from being damaged by clamping, and meanwhile, the hemisphere 4 is uniformly stressed by clamping tension.
As shown in fig. 1 and 8, the processing device for a ball valve sphere provided by the embodiment of the application further comprises an upper adjusting block 7. The upper adjusting block 7 is arranged between the first support 2 and the hemispherical body 4, and the upper adjusting block 7 is sleeved on the upper mandrel 5.
In the prior art, when machining the hemisphere 4, it is difficult for the machine tool to adjust the eccentric sizes of the center lines of the upper and lower mandrels 5 and 6 and the center line of the hemisphere 4. Therefore, the processing quality of the hemispherical body 4 is often affected for this reason. According to the embodiment of the application, the size of the upper adjusting block 7 is designed and manufactured according to the eccentric size required by the hemispheroids 4, so that the eccentric size of the hemispheroids 4 can be ensured and the quality of the manufactured ball of the ball valve can be ensured when the hemispheroids 4 are processed.
As shown in fig. 1 and 9, the processing device for a ball valve sphere provided by the embodiment of the application further comprises a lower adjusting block 8. The lower adjusting block 8 is arranged between the second support 3 and the hemispherical body 4, and the lower adjusting block 8 is sleeved on the lower mandrel 6.
It should be noted that, the size of the lower adjusting block 8 is also designed and manufactured according to the eccentric size required by the hemisphere 4, and in the embodiment of the application, the matching use of the upper adjusting block 7 and the lower adjusting block 8 can finely adjust the position of the hemisphere 4 along the central line direction of the upper mandrel 5 and the lower mandrel 6, so as to reduce the machining deviation; when the hemispheroids 4 are processed, the eccentric size of the hemispheroids 4 is more accurate, so that the quality of the manufactured ball valve spheres is better ensured.
As shown in fig. 1 to 3, the processing device for a ball valve sphere provided by the embodiment of the application further comprises a transition disc 9. The transition disc 9 is arranged on one side of the chassis 1 far away from the hemispheroids 4, and the transition disc 9 is detachably connected to the machine tool connection end.
It is difficult to directly connect the ball valve ball to the machine tool through the chassis 1 because the processing device of the ball valve ball has a large mass. Sometimes the accuracy of the processing means of the ball valve ball is impaired, so that the chassis 1 is divided into a chassis 1 and a transition disc 9. Due to the arrangement of the transition disc 9, the chassis 1 is prevented from being directly installed with a machine tool, so that the ball valve ball machining device is conveniently installed on the machine tool, and the ball valve ball machining device is conveniently disassembled from the machine tool.
Before the hemispheroids 4 are installed, the center of the device is found according to the correction excircle of the chassis 1, so that the rotation center of the chassis 1 is ensured to be coincident with the rotation center of the machine tool; aligning the center of the sphere according to the sphere size and the eccentric size, and then connecting the hemispherical body 4 with a processing device of the ball valve sphere and fastening.
In this specification, each embodiment is described in a progressive manner, and the same or similar parts of each embodiment are referred to each other, and each embodiment is mainly described as a difference from other embodiments.
The above embodiments are only for illustrating the technical solution of the present application, and not for limiting the present application; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced with equivalents; such modifications and substitutions do not depart from the spirit of the application.
