Abstract
The utility model discloses a tooling and fixture for processing eccentric orifices of a valve body of a top entry eccentric ball valve. The tooling and fixture solves the key problems that multiple locatings and multiple fixtures are required, processing is difficult and accuracy cannot be guaranteed in processing the eccentric orifices of a valve body of a top entry eccentric ball valve. The tooling and fixture is characterized in that a supporting body is connected with one side of a first connecting flange off the central axis. The cross section of the supporting body is L-shaped. A part of the supporting body, which is perpendicular to the first connecting flange, is provided with a circular through hole and connected with a locating plate. The locating plate is also provided with a circular through hole. The central axis of the through hole on the locating plate overlaps the central axis of the through hole on the supporting body. The locating plate is provided with a compacting device and an adjustable clamping device. A holding device of the valve body of the eccentric ball valve is formed by the compacting device, the adjustable clamping device and the circular through hole on the locating plate. The holding device is capable of connecting with a second connecting flange after being separated from the supporting body. According to this arrangement, the method that three eccentric orifices are processed on the valve body with one tooling and fixture by means of the replacement of flanges without the removal of main fixtures is realized, so that the high processing accuracy can be guaranteed.
Description
Technical field
The utility model patent relates to a kind of frock clamp of upper dress formula eccentric ball valve valve body eccentric orfice processing, is mainly used in the processing of the valve body eccentric orfice of dress formula eccentric ball valve.
Background technology
At present, known upper dress formula eccentric ball valve valve body eccentric orfice processing method exists needs many cover frock clamps just can finish processing, causes positioning reference plane inconsistent, and manufacturing procedure complexity and mismachining tolerance are larger, the problems such as defect rate height.
Summary of the invention
The utility model provides a kind of use two adpting flanges in order to solve above these problems, shares the frock clamp that a cover valve body possesses the fastener of positioning function.
The main technical scheme that adopts is as follows:
A kind of frock clamp of upper dress formula eccentric ball valve valve body eccentric orfice processing, adpting flange 2 departs from central shaft one side and connects supporting mass 6, described supporting mass 6 cross sections are L-type, vertical adpting flange 2 parts arrange manhole, vertical adpting flange 2 part connected positioning plates 5, on the described location-plate 5 manhole is set also, this through hole axle center is consistent with the axle center of the manhole of supporting mass 6, dispose hold down gag on the location-plate 5, manhole on adjustable clamping device and the location-plate 5 consists of the fastener of valve body jointly, and described fastener can be connected on the adpting flange 13 after breaking away from supporting mass 6.
Further, be connected with balancing weight 1 on the described adpting flange 2.
Further, the manhole of described supporting mass 6 is provided with positioning sleeve 7.
Further, described hold down gag is pressing plate 3 and the screw that connects pressing plate 3 and location-plate 5.
Further, described clamping device is at least two alignment pins 10 that cooperate each other, the screw that 10 1 connected positioning plates 5 of described alignment pin, the horizontal relative position in other end are provided with screw and cooperate with this screw.
The beneficial effects of the utility model are:
1. a cover frock realizes the effect of two cover frocks by two adpting flange designs, effectively reduces the frock cost and increases work efficiency, and increases positioning accuracy; 2. guarantee the eccentricity issues of valve body by the positioning sleeve adpting flange, utilize the concentricity of lathe itself more can guarantee eccentric accuracy.
Description of drawings
Fig. 1 is the side-looking sectional structure chart of the utility model first set frock.
Fig. 2 is the structure chart of facing of the utility model first set frock.
Fig. 3 is the sectional structure chart of facing of the utility model the second cover frock.
Fig. 4 is the plan structure figure of the utility model the second cover frock.
1. balancing weights, 2. adpting flanges, 3. pressing plates, 4. soket head cap screws, 5. location-plates, 6. supporting masses, 7. positioning sleeves, 8. linings, 9. fixed alignment pin 10. alignment pins 11. soket head cap screws 12. soket head cap screws 13. adpting flanges among the figure.
The specific embodiment
In Fig. 1,2, balancing weight 1 adpting flange 2 pressing plates 3 soket head cap screws 4 location-plates 5 supporting masses 6 positioning sleeves 7 linings 8 fixed alignment pin 9 alignment pins 10 soket head cap screws 11 soket head cap screws 12 are assembled one by one, guaranteed precision.
1) will need the valve body of eccentric hole of vehicle to be installed on the supporting mass by location-plate, supporting mass and balancing weight will be installed on the adpting flange.
2) valve body is fixed by alignment pin, pressing plate, soket head cap screw, and by positioning sleeve, fixed alignment pin location.
3) when a whole set of frock is installed on the lathe, the center of having departed from lathe spindle by the rotation valve body eccentric orfice center of lathe spindle makes lathe tool can accurately car go out the eccentric orfice of valve body.
In Fig. 3,41 adpting flange of balancing weight among Fig. 1,2,2 supporting masses, 6 positioning sleeves 7 are taken off one by one, the residue frock is installed in and guarantees on the adpting flange 13 that precision gets final product.
1) will need the valve body of eccentric hole of vehicle to be installed on the adpting flange 13 by location-plate 5.
2) owing to made off-centre, install valve body when location-plate and realized realizing eccentricly with flange center that when a whole set of frock was installed on the lathe, the lathe tool by lathe spindle can accurately car goes out the eccentric orfice of valve body.
What more than enumerate only is a specific embodiment of the present utility model.Obviously, the utility model can also have many distortion, and all distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
