Fig. 2 is a right view of the present invention.
Fig. 3 is a vertical view of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure, the present invention mainly by measuring 1, fixed positioning piece 2, bolt 3, stretching screw 4, handwheel 5, compress parts such as keeper 6, opening pressing plate 7, tie rod 8, O type elastic ring 9, front end measured hole 10, square measured hole 11, round measured hole 12, attachment bolt 13, bearing pin 14, backstay 15 and before measurement body 16 and form.
This expandable combined detection tool, it comprises measuring 1, fixed positioning piece 2, bolt 3, stretching screw 4, handwheel 5, compress keeper 6, opening pressing plate 7, tie rod 8, O type elastic ring 9, attachment bolt 13, bearing pin 14, backstay 15 and before measurement body 16, fixed positioning piece 2 is fixed on the measuring 1 by dog screw 3, fixed positioning piece 2 part overhangs concrete outer 1, travelling carriage is provided with tie rod 8 in 1 outside concrete, the front end of tie rod 8 is provided with the step circle, opening pressing plate 7 inserts in the step circle of tie rod 8, the rear end of tie rod 8 is provided with screw thread, this screw thread and handwheel 5 are spirally connected, slip cap is connected to and compresses keeper 6 on tie rod 8, this rearward end that compresses keeper 6 is a cylindrical section, this leading section that compresses keeper 6 is the lug body, the lug body diameter is greater than the cylindrical section external diameter, described fixed positioning piece 2 closely is socketed on the cylindrical section that compresses keeper 6, the lug body that compresses keeper 6 is provided with a step circle, on the step that compresses keeper 6 is round, be with O type elastic ring 9, compress on the cylindrical section of keeper 6 and be bolted with stretching screw 4, the rear end bending of stretching screw 4 also is pressed against on the fixed positioning piece 2, be installed with before measurement body 16 by attachment bolt 13 on the measuring 1, be provided with bearing pin 14 and backstay 15 between measuring 1 and the before measurement body 16, offer front end measured hole 10 on the before measurement body 16, offer square measured hole 11 and round measured hole 12 on the measuring 1.
Closely cooperate by dog screw 3 between fixed positioning piece 2 and the measuring 1, fixed positioning piece 2 part overhangs concrete outer 1, certain space is provided for the clamping location of workpiece, compressing keeper 6 is slidingly matched with fixed positioning piece 2, the gap can not be big, and the certain space of adjusting of existence in vertical direction, compress keeper 6 and be provided with a step circle, O type elastic ring 9 is enclosed within on the step circle that compresses keeper 6, O type elastic ring 9 contacts with fixed positioning piece 2 during clamping workpiece, stretching screw 4 is threaded with compressing between the keeper 6, is used to limit the described stroke that compresses keeper 6, and O type elastic ring 9 tie rods 8 and compressing between the keeper 6 are slidingly matched, tie rod 8 front ends are provided with the step circle, opening pressing plate 7 inserts in the step circle of tie rod 8, and the rear end of tie rod 8 is provided with screw thread, and this screw thread is threaded with handwheel 5.By compressing the endoporus of the O type elastic ring 9 realization tensioner workpiece between keeper 6 and the fixed positioning piece 2, tie rod 8 has the step circle, and tie rod 8 can be pulled out from behind, does not influence clamping workpiece like this, also can shorten the front end measurement space.
