Description
Technical field
The utility model is related to valves to fabricate field, especially a kind of for when to valve flanges facing pair
The positioning fixture that valve is positioned.
Background technology
Valve is the control unit in fluid delivery system, have cut-off, adjusting, water conservancy diversion, prevent countercurrently,
The functions such as voltage stabilizing, shunting or overflow pressure relief.For the valve of fluid control systems, from simplest shut-off valve to pole
For various valves used in complicated robot control system(RCS), kind and specification are quite various.Turning is carried out to valve flanges end face
When, it first has to position valve using fixture, valve can only be rotated and cannot be occurred in other directions any around its central axes
Displacement.The positioning fixture of China's production at present can not reach good locating effect, and valve is caused to generate in process
It is unqualified to may result in processing for displacement when carrying out turning to valve in this way；Also there is part positioning fixture that can play good fixed
Position effect, but it is complicated, and cost of manufacture is higher, increases the cost of enterprise.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of valve flanges facing positioning fixtures, solve existing
Have when carrying out turning to valve flanges end face in technology that positioning fixture positioning is inaccurate and positioning fixture cost is higher and structure mistake
In complicated problem.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of valve flanges facing positioning fixture, which is characterized in that including clamp body, clamp body is cylinder, folder
Specific length is less than the length of valve body and outer diameter is 0.03 millimeter smaller than the internal diameter of valve body, and both ends are respectively arranged with cylindric first
Protrusion and the second protrusion, first protrusion and the second convex surfaces are both provided with right-handed thread, and left locating piece is frustum cone structure,
First raised corresponding position is being provided with cylindric first groove, inside is provided with axis hole and keyway on the left of left locating piece, and the right side is fixed
Position block is frustum cone structure, and the second raised corresponding position is being provided with cylindric second groove, is being opened at right locating piece right center
There are coniform locating slot, first groove and the second groove inner surface to be both provided with right-handed thread, the left locating piece and the right side
The end face diameter of locating piece is both greater than the internal diameter of valve body.
Further, the left end face of the left locating piece is provided with the first in command.
Further, the right end face of the right locating piece is provided with second handle.
The utility model has the advantages that：This positioning fixture is easy to use, is easily installed and dismantles, to valve
Accurate positioning when being positioned, it is ensured that valve will not generate displacement in any direction, to reach higher turning effect；And
This positioning fixture cost is relatively low, simple in structure, and production cost has been saved for valve production and processing enterprise.
Description of the drawings
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is valve mechanism schematic diagram.
Specific implementation mode
As shown in Figure 1, 2, a kind of valve flanges facing positioning fixture, which is characterized in that including clamp body 1, fixture
Body 1 is cylinder, and the length of clamp body 1 is less than the length of valve body 4 and outer diameter is 0.03 millimeter smaller than the internal diameter of valve body 4, both ends point
It is not provided with cylindric first protrusion 11 and the second protrusion 12, first protrusion, 11 and second raised 12 surfaces are both provided with the right side
Screw thread is revolved, left locating piece 21 is frustum cone structure, and the first raised 11 corresponding positions are being provided with cylindric first groove 2, Zuo Ding
The position left side of block 21 is internal to be provided with axis hole 23 and keyway 24, and right locating piece 31 is frustum cone structure, with the second raised 12 corresponding positions
It is provided with cylindric second groove 3, coniform locating slot 33,2 He of the first groove are provided at 31 right center of right locating piece
Second groove, 3 inner surface is both provided with right-handed thread, and the end face diameter of the left locating piece 21 and right locating piece 31 is both greater than valve
The internal diameter of body 4.The left end face of the left locating piece 21 is provided with the first in command 22.The right end face of the right locating piece 31 is set
Second handle 32 is set.
When carrying out turning to the end face of flange 6 of valve, first clamp body 1 is put into valve body 4, then by left locating piece 21 and the right side
Locating piece 31 puts on the first protrusion 11 and the second protrusion 12 respectively, and operation employee is by rotating the first in command 22 and second handle 32
Left locating piece 21 and right locating piece 31 are tightened, the central axes 13 of positioning fixture and the central axes 41 of valve overlap, since a left side is fixed
Position block 21 and the end face diameter of right locating piece 31 are both greater than the internal diameter of valve body 4, so left locating piece 21 and right locating piece when tightening
31 are adjacent to generation stiction with 4 inner wall of valve body becomes an entirety, at this time by the key on the transmission shaft and transmission shaft of lathe point
It is not corresponding with axis hole 23 and keyway 24 engagement, start lathe so that transmission shaft is rotated counterclockwise, positioning fixture and valve composition it is whole
Body is also that axis rotates counterclockwise with central axes 41, at this moment uses the cutter on lathe to carry out turning to end face of flange 6, processes close
