Abstract
A kind of butterfly valve valve assemblying presses frock, including：Support；The power section on support is connected to, power section includes pressure head；Position portion, position portion includes positioning seat, and positioning seat is provided with support member, and valve block is located in support member, and position portion also includes the limiting component being engaged with valve block.The rotation riveting mode that valve block is assembled is changed into the processing that presses by this frock, so as to avoid the defect that the rivet that gap is caused between rotation riveting metapore and rivet is easy to fracture；This tool locating part ensure that the stabilization for the middle location of workpiece that presses, and improve machining accuracy；This frock has the simple in construction, precision that presses height, the advantage of workpiece service life length.
Description
Technical field
The utility model is related to butterfly valve processing technique field, and machining accuracy is assembled more particularly, to a kind of valve block that improves
Butterfly valve valve assemblying presses frock.
Background technology
Butterfly valve is a kind of control valve for rotating the open and close to realize passage around valve shaft by valve block, in pipeline
It is upper to play a part of to cut off and throttle.Assembling mode is between traditional valve block and valve shaft：Valve block and rocker arm shaft are loaded into valve body；Plus
Frock distribution（Including milling, brill, hinge process）；Rivet is inserted in the pilot hole in valve block and valve shaft；Rotation riveting is carried out to rivet
It is fixed.The technique has the drawback that：Revolve after riveting that simply rivet head exposed parts diameter becomes big, rivet diameter is not in valve block
Become, so that there is gap between rivet and valve block after riveting, in the hot environment normally used after butterfly valve dispatches from the factory, rivet
It is easily broken off in the case where shearing and wearing and tearing double action, in turn results in product failure, and if the hole of assembling processing is too small, then rivet
It is difficult to pack into pilot hole.
The content of the invention
The utility model provides a kind of butterfly valve valve block frock that presses, between being eliminated after the processing that presses between hole and rivet
Gap, and the one-shot forming that presses, improve processing efficiency, and the technical scheme of use is：A kind of butterfly valve valve assemblying presses frock,
It is characterized in that：The frock includes：Support；The power section of connection on the bracket, the power section includes pressure head；
Position portion, the position portion includes positioning seat, and the positioning seat is provided with support member, and valve block is located at the support member
On, the position portion also includes the limiting component being engaged with valve block.
Technical characteristic of the present utility model also has：The limiting component includes nylon block, and the nylon block is fixed on positioning
On seat, and there is inclined plane upward and that the valve block coordinates.
Technical characteristic of the present utility model also has：The limiting component also includes limited block, and the limited block is fixed on institute
State on support, and with the groove coordinated with valve shaft.
Technical characteristic of the present utility model also has：The support member is rivet support pin, and described supporting pin one end is fixed
On positioning seat, the other end has the circular groove coordinated with rivet head.
Technical characteristic of the present utility model also has：The power section also includes installing gas-liquid pressure-boosting on the bracket
Cylinder, the pneumohydraulic pressure-cylinder includes the pressure head.
The beneficial effects of the utility model are：The rotation riveting that valve block is assembled is changed into the processing that presses by this frock, so as to keep away
Exempt to revolve the defect that the rivet that gap is caused between riveting metapore and rivet is easy to fracture；This tool locating part, which ensure that, to press
The stabilization of the location of workpiece, improves machining accuracy；This frock has that the simple in construction, precision that presses is high, workpiece service life length it
Advantage.
Brief description of the drawings
Accompanying drawing 1 is the utility model structural representation, and accompanying drawing 2 is to remove structural representation after power section in accompanying drawing 1, attached
Fig. 3 is the use state schematic diagram of accompanying drawing 2, and accompanying drawing 4 is that rotation riveting installs gap schematic diagram with pilot hole, and accompanying drawing 5 is the utility model
Middle rivet installs gap schematic diagram with pilot hole, wherein 1 is pneumohydraulic pressure-cylinder, 2 be support, and 3 be pressure head, and 4 be rivet support pin,
5 be nylon block, and 6 be limited block, and 7 be positioning seat, and 8 be valve block, and 9 be valve shaft, and 10 be rivet, and 11 be valve body.
Embodiment
Below in conjunction with the accompanying drawings, embodiment of the present utility model is illustrated.The utility model discloses one kind
Butterfly valve valve assemblying presses frock, and frock includes：Support 2；The power section on support 2 is connected to, power section includes pressure
First 3, in addition to moved up and down with dynamic head 3, pneumohydraulic pressure-cylinder 1 on support 2；Position portion, location division subpackage
Positioning seat 7 is included, positioning seat 7 is provided with support member, and valve block 8 is located in support member, position portion also includes matching with valve block 8
The limiting component of conjunction.
In the present embodiment, limiting component includes nylon block 5, and nylon block 5 is fixed on positioning seat 7, and with upward, with
The inclined plane that riveting status lower disc 8 coordinates；Limiting component also includes limited block 6, and limited block 6 is fixed on support 2, and is had
The groove coordinated with valve shaft 9；Support member is rivet support pin 4, and the one end of rivet support pin 4 is fixed on positioning seat 7, the other end
With the circular groove with the head fits of rivet 10.
In use, the valve body after assembling is loaded into the frock, press after button, pneumohydraulic pressure-cylinder 1 is descending with dynamic head 3,
Press processing to the rivet row loaded in valve block, and pressure head 3 rises after riveting, and once pressing machines.This frock to press
Power is under the premise of definite value, rivet is effectively filled with the gap between rivet and mounting hole, while rivet exposed parts also obtain pier
Slightly, it placed rivet to come off, and extend workpiece service life.
Certainly, described above is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
The variations, modifications, additions or substitutions that the those of ordinary skill in art field is made in essential scope of the present utility model, also belong to
In protection domain of the present utility model.
