Fig. 2 is the A-A cross section view of Fig. 1.
Fig. 3 is that the B of Fig. 1 is to view.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
Like Fig. 1～shown in Figure 3: the present invention mainly transmits bar 10, bearing 11, handle 12, second by tong-test ammeter cover 1, contiguous block 2, screw 3, measuring spring 4, body 5, screw 6, handle 7, first guide pin bushing 8, first stop screw 9, first and transmits bar 13, first back-moving spring 14, rule body 15, first pin, 16, second back-moving spring 17, gauge head 18, first cover plate 19, second stop screw 20, second guide pin bushing 21, second cover plate 22 and second pin 23 etc. and form.
Hole slot diameter measurement mechanism in of the present invention, the upper end of said body 5 is through the contiguous block 2 that is threaded.Be press-fitted tong-test ammeter cover 1 on the contiguous block 2, had screw 3 to be used for clamping dial gauge in the contiguous block 2.Second cover plate 22 is housed on the said body 5, and body 5 connects handle 7 through screw 6.First guide pin bushing 8 and second guide pin bushing 21 are equipped with in perforate in the middle of the body 5.Be equipped with first in said first guide pin bushing 8 and second guide pin bushing 21 and transmit bar 10, spacing through first stop screw 9, first transmits bar 10 middle flutings is equipped with bearing 11, and handle 12 is loaded on the body 5 through second pin 23, and handle 12 contacts with bearing 11.Be set with measuring spring 4 on the first transmission bar 10; First transmits bar 10 through measuring spring 4 transferring power, and rule body 15 is contained in body 5 belows through being threaded, and perforate is equipped with second and is transmitted bar 13 in the middle of the rule body 15; Be set with first back-moving spring 14 on the second transmission bar 13; Second transmits bar 13 resets through first back-moving spring 14, and second transmits bar 13 and gauge head 18 through the inclined-plane transferring power that contacts, and second back-moving spring 17 is housed on the gauge head 18; Second back-moving spring 17 resets gauge head 18; Second back-moving spring 17 is pressed in the gauge head 18 by first cover plate 19 through first pin 16, stop screw 20 is housed in first cover plate 19 transmits bar 13 positions in order to limit second, and gauge head 18 slides in the groove of rule body 15 through first cover plate 19.
Shown in accompanying drawing 1, it is clearance fit that first guide pin bushing, 8, the second guide pin bushings 21 and first transmit bar 10, and tolerance clearance is less, and purpose is that the radial missing that bar 10 produces is transmitted in control first when moving in first guide pin bushing, 8, the second guide pin bushings 21; The second transmission bar 13 is clearance fit with rule body 15, and tolerance clearance is less, and purpose is that the radial missing that produces when bar 13 moves is transmitted in control second in advising body 15; The purpose of mounting knob 7 is to make things convenient for personnel's one hand to pick up cubing to operate; Bearing 11 produced and rolls when handle 12 contacted with bearing 11, so it is less to regain first power when transmitting bar 10; Gauge head 18 is a clearance fit in the square groove of rule body 15, and tolerance clearance is less, and purpose is the radial missing of control gauge head 18 in rule body 15; The stroke that stop screw 20 can be used for regulating the second transmission bar 13 is housed in first cover plate 19.
The principle of work of the present invention and the course of work:
The measurement state; Release handle 12, under the acting force of measuring spring 4, first transmits bar 10 moves downward; First transmits bar 10 transmits bar 13 with force transmission to second; Second transmits bar 13 passes to gauge head 18 through the inclined-plane with ergometry, and gauge head 18 ejects, and the spring force of measuring spring 4 need overcome the power of first back-moving spring 14 and second back-moving spring 17.
The recovery state, pressing handle 12 transmits bar 10 with first and upwards mentions, and second transmits bar 13 regains under the power effect of first back-moving spring 14 and second back-moving spring 17 respectively with gauge head 18, and at this moment gauge head 18 withdrawals can propose workpiece with whole device.
In school zero, at first pressing handle 12 will advise body 15 then and will be placed in the calibrating device datum hole, release handle 12, and gauge head 18 ejects, and transmits bar 13 and first through second and transmits bar 10 interior hole slot diameter variation amount is passed, and the numerical value of demonstration is returned to zero.
After accomplish in school zero, just can measure workpiece with same procedure, the numerical value that surveying instrument shows be exactly in the variable quantity of the relative and calibrating device of hole slot diameter.
