Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Gear angle cubing as shown in Fig. 1, Fig. 2, Fig. 3 has base plate 1, and base plate 1 two ends are respectively equipped with a column 2, is sheathed on sleeve 3 rear ends outside the column 2, and sleeve 3 front end sleeves are located in the slide block 4, and corresponding second column 13 of sleeve 3 front ends.Be arranged with mandrel 5 in the sleeve 3, mandrel 5 rear ends are connected with handle 7 by spring 6, and front end has top 8.The slide block 4 laterally inclined dial gauges 9 that are provided with, the vertical contact of the thimble of this dial gauge 9 is on slide block 4 surfaces, and two

taper pins

11,12 that are arranged with on slide block 4 inwalls are positioned at mandrel 5 tops.Be provided with toply 14 in the column 13, this top 14 is provided with in opposite directions with mandrel top 8 simultaneously.The level of going back on the base plate 1 is provided with dial gauge 15, also is provided with Working piece positioning device simultaneously between two columns 2,3.Working piece positioning device comprises register pin 16, register pin 16 axis normal are in base plate 1, be arranged with spring 17 on the register pin 16, on the upper and lower side of spring 17

step

18,19 that contact is provided with in register pin 16 middle parts and bottom respectively, register pin 16 bottoms connect fork 20 1 ends, the other end of fork 20 connects the thimble of dial gauge 15, and fork 20 also is provided with spring lever 31 at this end.13 in the described column 13 top 14 and column are connected by spring 21.

For the convenient displacement that limits slide block 4, also be provided with groove 40 on the slide block 4, this groove 40 matches with the backstay 22 that column 2 is provided with.

For better workpiece being positioned, register pin 16 tops also are provided with positioning ball 23, and steel ball 23 can better be placed in the workpiece teeth groove, and workpiece is positioned.

When using this cubing, earlier slide block 4 is slided left, its sliding distance is by 40 controls of the groove on backstay 22 and the slide block 4, and when contact groove 40 bottoms, backstay 22 top, slide block 4 can not continue to slide left again.Handle 7 is to pressing down then, and extension spring 6 also drives mandrel 5 and moves to left, and standard component 30 covers is placed between mandrel top 8 and the column top 14 again.The structure of its standard component 30 such as Fig. 4, shown in Figure 5, standard component 30 have pin 24, die cavity groove 25, also are provided with teeth groove 26 on the outer wall.Its angle that will measure is the number of degrees of the angle ∠ A between pin 24 and the tooth 29.Die cavity groove 25 ends of standard component are aimed at mandrel 5, and other end alignment post is top 14, and teeth groove 26 is aimed at the positioning ball 23 of locating devices, as shown in Fig. 6, Fig. 7.Decontrol handle 7, spring 6 returns back to original position, and mandrel 5 is homing also, and mandrel top 8 stretches in the die cavity groove 25 of standard component, and its standard component is clamped between mandrel top 8 and the column top 14, and positioning ball 23 is positioned at standard component teeth groove 26.Rotate standard component, 26 liang of flank of tooth of positioning ball 23 and standard component teeth groove are contacted well, and with 15 pairs zero of second dial

gauges.Taper pin

11,12 inserts in the standard component die cavity groove 25 gently when then slide block 4 slowly being slided to the right, the slide block 4 that swings then contacts two

taper pins

11,12 respectively with die

cavity trough rim

27,28, and make both sides stressed evenly, then with 9 pairs zero of first dial gauges.Standard component is taken off, and workpiece for measurement is put into cubing, and is identical with said process, first turning of work piece, and purpose is to allow at every turn clamping of workpiece be consistent, it clamps the reading of whether adopting second dial gauge 15 unanimously and confirms.In the workpiece rotating process, workpiece teeth groove two flank of tooth compressing register pin 16 moves down, because register pin 16 bottoms connect fork 20 1 ends, the other end of fork 20 connects the thimble of second dial gauge 15, the two ends of fork 20 are isometric simultaneously, therefore the amount that fork 20 left ends move down with right-hand member moves up is identical, and this amount of movement is the reading of second dial gauge 15, and reading represents that in-0.05～+ 0.05 scope workpiece clamp installs to the position.Last slide block 4 moves to right taper pin is inserted in the workpiece cavity groove, and two taper pins are contacted with the die cavity trough rim respectively, and makes both sides stressed evenly, read the reading of first dial gauge 9 then, this reading is a deviate, and with this deviate and the contrast of angle collation table, converting draws the actual angle value.
