Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
Such as Fig. 1~5, a kind of control-rod geometric tolerance detection device, including pedestal 1, tailstock supporting block 2, tailstock sealing plate 3,
Slide bar 4, dial framework 5, amesdial 6, spring cylinder 7, handle 8 and graduated scale 9；The tailstock supporting block 2 has two pieces to be oppositely arranged on
1 two sides of pedestal offer V-groove 21 in Founder thereon, are connected on the outside of one of tailstock supporting block 2 tangent with V-groove 21
The tailstock sealing plate 3 kept out of control-rod 10 is formed, another piece of 2 outside of tailstock supporting block is connect with spring cylinder 7, and connection type can be with
It is that puller bolt is installed in the threaded hole that 7 vertical end seat supports block of spring cylinder, 2 direction opens up；During the spring cylinder 7 is
Hollow structure, and perforation offers through-hole 71, such as Fig. 3,4；Back-off pull rod 72 is equipped in the through-hole 71；In the back-off pull rod 72
The boss 73 that there is diameter to be greater than through-hole 71 in portion, to guarantee that back-off pull rod 72 will not be drawn out through-hole 71, always in spring cylinder 7
Interior movement is set with spring away from back-off 72 tailstock supporting block of pull rod, 2 side and (spring is not shown in the figure, installation site is being schemed
Show at middle spring installation position 20), it faces 2 side of tailstock supporting block and is placed in V-groove 21 and pushes against control-rod 10 to tailstock
Sealing plate 3；The both ends of the spring is connect with handle 8 and spring cylinder 7 respectively；The slide bar 4 has two to be arranged in parallel in two tailstocks
Between supporting block 2；The dial framework 5 is slidably set on slide bar 4；The amesdial 6 is arranged on dial framework, and indicator vertically to
The lower line for being directed toward two V-groove 21V word tips；The graduated scale 9 is set on pedestal 1 along 4 length direction of slide bar.
Control-rod 10 is installed first, handle 8 is pulled outward, back-off pull rod 72 is moved back outward and (at most retreats to boss 73 to be stuck in
At the through-hole 71 in left side), while the spring that connection is arranged between handle 8 and spring cylinder 7 is in tensional state, it then will control
Bar 10 processed is placed in two V-grooves 21, and one end of control-rod 10 is against on tailstock sealing plate 3, following release handle 8, spring
It resets, control-rod 10 is pushed against on tailstock sealing plate 3 by back-off pull rod 72.The indicator of amesdial 6 is kept to be vertical downwardly directed at this time
The outer surface of control-rod 10.
Cylindricity detection: rotating handle 8 drives control by pushing against frictional force under the abutting effect of back-off pull rod 72
Bar 10 rotates, and checks 6 indicator of amesdial bounce situation, and then detect the cylindricity of the part.
Linearity surveying: pulling dial framework 5, and linear slide can be done on slide bar 4, checks 6 indicator of amesdial bounce feelings
Condition, and then detect the straightness of the part, graduated scale 9 can then calculate the distance of the movement of dial framework 5, and then calculate unit length
Straightness tolerance cases.
The utility model is on the basis of being equally able to achieve control-rod geometric tolerance (cylindricity, straightness) detection, relatively
The imports measuring instruments such as existing axial profile instrument, pneumatic measuring instrument, with of simple structure and low cost, easy to operate etc.
