A kind of balanced valve valve body mesopore fixture for processing device
Technical field
The utility model relates to machining apparatus technical field, is specifically related to a kind of balanced valve valve body mesopore fixture for processing device.
Background technology
Balanced valve is a kind of adjustment type valve with number lock specific function, adopt once-through type valve body structure, there is better equal percentage flow characteristic, can reasonably dispense flow rate, effectively solve the room temperature problem uneven in temperature existed in heat supply (air-conditioning) system.Pressure drop and flow can be regulated exactly simultaneously, in order to improve liquid flowing state in pipe network system, reach the object in pipe network fluid balance and the source of saving.Valve is provided with open degree instruction, aperture locking device and the little valve of pressure measurement for flow measurement, as long as load onto the balanced valve of suitable specification at each branch road and user entry, and lock after carrying out disposable debugging with intelligent instrument specially for same, the total Water of system to be controlled in rational scope thus to overcome the un-reasonable phenomenon of " large discharge, the little temperature difference "; At present, existing valve manufacture enterprise is in line balancing valve process, because valve body is comparatively large, machine tool cannot complete processing tasks, usually needs by heavy duty machine tools equipment, but when processing valve mesopore, heavy duty machine tools cannot directly process valve body mesopore, need by different fixtures by repeatedly processing, and traditional fixture needs repeatedly to adjust angle just can complete processing to valve body mesopore, not only working (machining) efficiency is low, and the machining accuracy of valve body mesopore is also difficult to ensure.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of balanced valve valve body mesopore fixture for processing device, the utility model not only efficiently solves the mesopore of existing balance valve body in process, needs handling adjustment angle repeatedly just can complete the processing to valve body mesopore, the above-mentioned processing mode problem that not only working (machining) efficiency is low, and owing to loading and unloading repeatedly, be difficult to the concentricity issues ensureing hollow processing.
The utility model is achieved through the following technical solutions:
A kind of balanced valve valve body mesopore fixture for processing device, comprise the stationary backplate (1) be fixedly connected with machine tooling table top, stationary backplate (1) is provided with installs through hole (11), stationary backplate (1) is fixedly connected with machine tooling table top by installing through hole (11), it is characterized in that: described stationary backplate (1) lower surface is vertically installed with fixed base plate (2), fixed base plate (2) bilateral symmetry is provided with movable holddown (3), upper movable holddown (3) two ends is connected with fixed base plate (2) is adjustable by leading screw (4), on two, movable holddown (3) outside is provided with lower locating piece (5), lower locating piece (5) two ends are fixedly connected with fixed base plate (2) by securing member (6), detent (51) is provided with inside twice locating piece (5) bodies.
The further Technological improvement plan of the utility model is:
Described upper movable holddown (3) two ends are symmetrically arranged with kidney-shaped adjustment hole (31), adjusting grooves (7) is provided with on the fixed base plate (2) of upper movable holddown (3) opposite position, length and upper movable holddown (3) match, and two leading screws (4) are all arranged in adjusting grooves (7).
The further Technological improvement plan of the utility model is:
Described lower locating piece (5) is positioned at adjusting grooves (7) outside, be arranged in parallel with upper movable holddown (3).
The further Technological improvement plan of the utility model is:
Described fixed base plate (2) is also provided with mesopore fine setting screw rod (8), mesopore fine setting screw rod (8) is arranged between movable holddown on two (3).
The utility model compared with prior art, has following obvious advantage:
One, the utility model fixture is arranged on process equipment chuck, two locating pieces and mesopore fine-tuning nut is used down to realize positioning action, the upper movable pressing board that bilateral symmetry is arranged realizes fixation, can realize location and assembling fast, improve the machining accuracy of working (machining) efficiency and mesopore.
Two, the utility model is by the adjustment to leading screw, adjusting grooves and lower locating piece distance, and highly versatile, can meet the middle hole machined of different size balanced valve, reduces the supporting cost of production of enterprise.
