Description
Technical field
The utility model relates to a kind of ball core roundness measurement frock.
Background technology
Ball core is the vital part of ball valve, and the dimensional accuracy of ball core, circularity, roughness, hardness directly affect the usability of ball valve complete machine.Therefore, ball core is complicated as vital part manufacturing process, and flow process is many, to size and positional precision influence factor more.
After the processing of sphere completes, be the key guaranteeing assembly quality, the particularly detection of ball core circularity to the detection of part quality.And ball core circularity is difficult to easy mode Measurement accuracy, and, use inconvenience high by existing three-coordinates measuring machine price.
Utility model content
The purpose of this utility model is to provide the ball core roundness measurement frock that a kind of measuring accuracy is higher, structure is simple, easy to operate.
A kind of ball core roundness measurement frock, its special feature is: comprise supporting box, and the upper surface of this supporting box is provided with gauge stand, and this gauge stand is connected with dial gauge by fixed bar; Outside this supporting box, handwheel is installed, this handwheel is fixedly mounted on a worm screw top, the bottom of this worm screw to be stretched in supporting box and is engaged with the transmission turbine be sleeved on transmission shaft, it is outer and be fixedly connected with a pedestal that this transmission shaft extend out to supporting box upper surface, is provided with groove on the base thus can places ball core to be detected.
Wherein fixed bar is L-type bar.
The inside surface of its further groove is inclined-plane or sphere.
Wherein the upper surface of supporting box is magnetic conductive material, and described gauge stand is Magnetic gauge stand.
Through probationary certificate, after adopting detection frock of the present utility model, coordinated with dial gauge by shake handwheel, can realize the roundness measurement to ball valve ball core quickly and easily, not only testing cost is low, and detection efficiency is high; , by Magnetic gauge stand and fixed bar, dial gauge is fixed meanwhile, the accuracy detected can be ensured further.The utility model also has structure advantage simple, easy to use, is especially applicable to the detection of ball valve ball core in enormous quantities.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of ball core roundness measurement frock, and comprise supporting box 1, the upper surface of this supporting box 1 is provided with gauge stand 10, this gauge stand 10 is connected with dial gauge 8 by fixed bar 9; Outside this supporting box 1, handwheel 6 is installed, this handwheel 6 is fixedly mounted on worm screw 5 top, the bottom of this worm screw 5 to be stretched in supporting box 1 and is engaged with the transmission turbine 4 be fixedly set on transmission shaft 3, it is outer and be fixedly connected with a pedestal 2 that this transmission shaft 3 part extend out to supporting box 1 upper surface, this pedestal 2 is provided with groove thus places ball core 7 to be detected.
Wherein fixed bar 9 is L-type bar thus is supported by dial gauge 8 and fix, and the inside surface of groove is inclined-plane or sphere.The upper surface of supporting box 1 is magnetic conductive material in addition, and described gauge stand 10 is Magnetic gauge stand, namely which is provided with permanent magnet.
Embodiment 1:
As shown in Figure 1, a kind of ball core roundness measurement frock of the present utility model comprises supporting box 1 and dial gauge 8, supporting box 1 is built with transmission shaft 3 and transmission turbine 4, transmission turbine 4 is connected with the worm screw 5 in supporting box 1, and handwheel 6 is equipped with on worm screw 5 top, and transmission shaft 3 is connected with the pedestal 2 outside supporting box 1, pedestal 2 is placed with ball core 7 to be measured, ball core 7 surface contacts with dial gauge 8, and dial gauge 8 is connected with Magnetic gauge stand by fixed bar 9, and Magnetic gauge stand is adsorbed on the outside surface of supporting box 1.
Particularly, pedestal 2 circumferential direction inside direction is provided with groove, and groove surface is inclined-plane or sphere.Further, pedestal 2 is connected with transmission shaft 3, transmission shaft 3 is connected with (transmission) turbine 4, and turbine 4 is connected with worm screw 5, and handwheel 6 is equipped with on worm screw 5 top, when handwheel 6 rotates, drive worm screw 5 to rotate, worm screw 5 drives turbine 4 to rotate, and turbine 4 drives transmission shaft 3 to rotate, final drive shaft 3 is with moving base 2 to rotate, and final pedestal 2 drives ball core 7 to rotate.Further, dial gauge 8 is fixed by fixed bar 9 and is contacted with ball core 7 to be detected.
During use, first be steadily positioned on pedestal 2 by ball core 7 to be measured, by dial gauge 8 fixed bar 9 fixation, contact is just pressed on sphere, large list index press-in one circle, the now little lattice of little table rotation 1, subsequently large list index for 0 scale mark, subsequently shake handwheel 6, pedestal 2 drives ball core 7 to be measured to rotate, observe the beat of pointer of dial gauge 8, the lower maxima and minima of meter, both differences are the circularity limit deviation detecting position sphere.Ball core circularity such as soft sealing ball valve requires 0.02 ~ 0.05.Ball core circularity for metal hard-sealing ball valve requires 0.01 ~ 0.02.Detect a rear flank, 180 ° have been turned to spheroid, repeated above-mentioned detection method, detect the circularity limit deviation of opposite side sphere.
