Among the figure: 1, V-type groove rotating disk 2, horn craving scale 3, pedestal 4, clamping screw 5, end cap 6, right angle screw rod 7, trip bolt I 8, ladder coupling shaft 9, trip bolt II

Embodiment: measure auxiliary clamp, it is characterized in that by V-type groove rotating disk, the horn craving scale, pedestal, clamping screw, end cap, the right angle screw rod, trip bolt I, ladder coupling shaft and trip bolt II constitute, V-type groove rotating disk one side is shaped on sleeve, on sleeve wall, make the threaded hole that trip bolt I and trip bolt II are installed, make the recess of established angle index dial at V-type groove rotating disk opposite side, be shaped on the V-type groove on the V-type groove rotating disk, be shaped on the V-type groove rotating disk to be shaped on 6 V-type grooves or the V-type groove rotating disk on 3 V-type grooves or the V-type groove rotating disk and be shaped on 8 V-type grooves, V-type groove center of turntable place is shaped on the through hole that the ladder coupling shaft is installed, make a threaded hole of dress right angle screw rod on each boss of V-type groove rotating disk, ladder coupling shaft one end is made the endoporus of established angle index dial, horn craving scale one side is made optical axis, make the mounting hole that the ladder coupling shaft is installed on the pedestal, screw rod one end in right angle is made external thread, the threaded hole of dress clamping screw is made in screw rod another end in right angle, and the endoporus that end cap is installed is made in the lower end of clamping screw; The ladder coupling shaft is contained on the pedestal, the ladder coupling shaft is connected with the pedestal interference fit, the ladder coupling shaft is not rotated, V-type groove rotating disk is contained on the ladder coupling shaft, V-type groove rotating disk is connected with ladder coupling shaft transition fit, trip bolt I and trip bolt II are contained on the V-type groove rotating disk, the horn craving scale is contained on ladder coupling shaft and the V-type groove rotating disk, horn craving scale and ladder coupling shaft interference fit, the horn craving scale does not rotate, the right angle screw on V-type groove rotating disk, is contained in clamping screw on the right angle screw rod, end cap is contained on the clamping screw.

V-type groove rotating disk is connected with ladder coupling shaft transition fit, V-type groove rotating disk can rotate with ladder coupling shaft center line, measure for the manual positioning of rotating of the direct clamping of rub-out action power that light part can lean on V-type groove rotating disk and ladder coupling shaft, need not tighten up with trip bolt I and trip bolt II, tighten up with trip bolt I and trip bolt II for heavier part.

The anglec of rotation of V-type groove rotating disk is read by the horn craving scale, and the circumferential edges of horn craving scale has the angle groove, and its minimum scale (resolution) can design according to needs.

V-type groove on the V-type groove rotating disk can have different sizes, on V-type groove rotating disk, can design and produce the V-type groove of varying number, as 3 V-type grooves, 6 V-type grooves, 8 V-type grooves etc., each V-type groove can part of clamping, and clampings are to be detected simultaneously can to realize a plurality of parts.

Detect for example:

Example 1: to detect the manufactured head angle is example, rivet shape as shown in Figure 7, the measurement requirement of general manufactured head angle detects 4 orientation angles as shown in Figure 8, provides the scope of angle value.The measuring equipment of selecting for use is generally noncontact radiographic measurement equipment, and as universal tool-measuring microscope, projector, optical three-coordinate etc., each projection can only be measured a direction.

Before not measuring auxiliary clamp, V-block commonly used at every turn can only rivet of clamping, measure the angle of a direction after, need manually the rotation rivet to general 45 ° of positions, again clamping again, measure the angle value of the 2nd direction, and then manually rotate rivet successively, measure to general 90 °, 135 ° positions, until measuring four direction manufactured head angle value, forwarding general 45 °, 90 °, 135 ° positions to entirely with sensation, is the estimated value that obtains by experience, and measuring error is big.

After the measurement auxiliary clamp has been arranged, be 1 ° measurement auxiliary clamp with having 3 V-type grooves and horn craving scale angular indexing value, 3 rivets are contained in respectively in 3 V-type grooves, as shown in Figure 9, the anglec of rotation is accurate to 1 °, and measuring equipment is selected universal tool-measuring microscope for use; The measurement auxiliary clamp that 3 rivets are housed is positioned on the worktable of universal tool-measuring microscope, manually rotate V-type groove rotating disk, No. 1 part is rotated to 0 ° of position, measure No. 1 part direction 3 position manufactured head angles as shown in Figure 8, transverse and longitudinal moves the slide plate of universal tool-measuring microscope then, adjust focal length, measure the angle value of other two relevant positions.

After measuring 0 ° of position manufactured head angle, manually rotate V-type groove rotating disk, No. 1 part is rotated to 45 ° of positions, as shown in figure 10, measure direction 4 position manufactured head angles as shown in Figure 8 No. 1, transverse and longitudinal moves the slide plate of universal tool-measuring microscope then, adjusts focal length, measures the angle value of other two relevant positions.

After measuring 45 ° of position manufactured head angles, manually rotate V-type groove rotating disk, No. 1 part is rotated to 90 ° of positions, as shown in figure 11, measure No. 1 part direction 1 position manufactured head angle as shown in Figure 8, transverse and longitudinal moves the slide plate of universal tool-measuring microscope then, adjusts focal length, measures the angle value of other two relevant positions.

After measuring 90 ° of position manufactured head angles, manually rotate V-type groove rotating disk, No. 1 part is rotated to 135 ° of positions, as shown in figure 12, measure No. 1 part direction 2 position manufactured head angles as shown in Figure 8, transverse and longitudinal moves the slide plate of universal tool-measuring microscope then, adjusts focal length, measures the angle value of other two relevant positions.

So far, the Angular Dimension measurement of three rivet four directions finishes.

This shows, the measurement auxiliary clamp has been arranged after, as long as clamping once, just can detect 3 parts simultaneously, the angle value of 4 directions of each part, not only can be quantitative provided the anglec of rotation and can also increase work efficiency greatly.

Example 2: detected catheter awl prostomum degree, select three coordinate measuring machine for use, during measurement, select the measurement auxiliary clamp of six V-type grooves for use, be placed on the worktable of three coordinate measuring machine, then 6 catheter cartridges are clipped in the V-type groove, vertical view is as shown in figure 13 behind the clamping.Handle three coordinate measuring machine and directly measure the awl mouth taper value of each conduit successively.

This shows that 6 of a clamping finishes testing.
