And second bearing, clutch shaft bearing and second bearing are in same horizontal line, in clutch shaft bearing and second bearing line of centres just
Top is provided with 3rd bearing, and 3rd bearing is connected by contiguous block with connecting rod, and base top is provided with compact heap, compact heap
Upper setting lock-screw, lock-screw lower end is resisted against on connecting rod during locking.
The diameter of the clutch shaft bearing, second bearing and 3rd bearing is φ 10mm, clutch shaft bearing and second bearing
Centre-to-centre spacing is 10.7mm.
The contiguous block is connected by the second shaft with link rotatable, and block and the gear are provided with the right side of 3rd bearing
Block is fixedly mounted on base, and pushing mechanism is provided with the left of 3rd bearing and promotes 3rd bearing to be resisted against block all the time
On.
The pushing mechanism includes fixed block, slide bar, sliding block and spring, and the slide bar is arranged in parallel in the lower section of connecting rod
And be connected by fixed block with connecting rod, spring and sliding block are set on slide bar, and the left end of spring is resisted against on fixed block, and right end supports
Lean against on sliding block, be resisted against on the right side of sliding block in 3rd bearing.
The bottom portion of groove centre position is in downward concave arc-shaped.The structure can to avoid clamped core bar with it is recessed
Trench bottom interferes, and ensures the rotating smoothness of core bar.
The compact heap can be rotated around its vertically-mounted axis.When unclamping lock-screw, can rotate backward compact heap,
Connecting rod is facilitated to rotate, in order to the core bar that clamping is to be detected.
The contiguous block is arranged on the back side of connecting rod, and contiguous block is located in groove during connecting bar locking.Contiguous block is arranged on company
The back side of bar, it is convenient to be detected with to core bar, avoid contiguous block and amesdial from interfering.
Compared with prior art, beneficial effects of the present invention are as follows：
1st, when accommodate core bar to be checked using the present invention, pivot link is only needed, core bar is inserted into clutch shaft bearing, the
Between two bearings and 3rd bearing, core bar can be compressed while tightening screw in compression connecting rod by tightening, and during inspection, only need to use
Hand, which stirs one of bearing, to drive core bar to rotate, and amesdial easy to use is tested.In addition, drive the by connecting rod
Three bearings carry out upper and lower movement, the core bar suitable for clamping different diameter specifications.
2nd, in the present invention, the diameter of clutch shaft bearing, second bearing and 3rd bearing is φ 10mm, clutch shaft bearing and
The centre-to-centre spacing of two bearings is 10.7mm, and the straight of core bar can be clamped when 3rd bearing and clutch shaft bearing, second bearing fit
Footpath is 1.82mm, therefore the present invention is suitable for the core bar of clamping diameter >=more than φ 2.0mm.
3rd, in the present invention, 3rd bearing is controlled by limited block and pushing mechanism, ensures 3rd bearing with even
The rotation of bar and during the decline risen, 3rd bearing is moved on the perpendicular bisector of clutch shaft bearing and second bearing line of centres all the time,
So that 3rd bearing is to compress the core bar of required detection vertically downward, it ensure that core bar rotates more in detection process
Steadily.
