Detailed description of the invention
Below in conjunction with accompanying drawing, principles of the invention and feature being described, example is served only for explaining the present invention, is not intended to limit the scope of the present invention.
As depicted in figs. 1 and 2, a kind of pull bar detecting device, including base plate 1, height gauge 2, lever indicator 3, lever indicator contact 4, cylindrical positioning pins 5 and quick clamping mechanism 6, described height gauge 2 and quick clamping mechanism 6 be the fixing both sides being placed in described base plate 1 upper end respectively, described height gauge 2 is set with the slide block 7 that can slide along described height gauge 2, described slide block 7 is fixedly connected with cross bar 8 near the side of described quick clamping mechanism 6, the described fixing lower end being placed in described cross bar 8 of lever indicator 3, described lever indicator 3 is linked by cross bar 8 and described slide block 7；The described fixing lower end being placed in described lever indicator 3 of lever indicator contact 4；Described cylindrical positioning pins 5 fixes the upper end being placed in base plate 1, and described cylindrical positioning pins 5 is in the lower section of described quick clamping mechanism 6 push-down head.
Preferably, also including cylinder backing pin 9, on the described fixing base plate 1 being placed between described height gauge 2 and quick clamping mechanism 6 of cylinder backing pin 9, and described cylinder backing pin 9 is in the side near described lever indicator contact 4.
Preferably, described height gauge 2 is two-tube height gauge.
Preferably, the side of described slide block 7 is provided with handwheel, rotates described handwheel and described slide block 7 can be driven vertically to slide on described height gauge 2.
Preferably, also including positive stop 10, described positive stop 10 is fixing to be placed on the described height gauge 2 base plate 1 away from the side of described quick clamping mechanism 6, and described positive stop 10 is in the lower section of described slide block 7.
Implementing this device, be lowered in the cylindrical positioning pins 5 on base plate 1 in pull bar 11 hole, the other end of pull bar 11 is close to cylinder backing pin 9, then passes through the other end in hole, quick clamping mechanism 6 compressing pull rod location；After compression, by adjusting height gauge 2 height, lever indicator contact 4 is moved up and down in tie rod hole, and then the upper allowance below nominal size of this hole bus is read by lever indicator 3, thus quickly determining that whether detection hole is overproof with the perpendicularity of benchmark bottom surface, positive stop 10 is to prevent generation making contact between lever indicator contact 4 and base plate 1.
