Detailed description of the invention
This utility model provides a kind of spline locking positioning pin mechanism for cubing, including being arranged at the set pin sleeve of cubing and being arranged in the alignment pin of set pin sleeve；
Alignment pin includes body and latch assembly；
Latch assembly for applying the chucking power of clamping part to be measured by body to set pin sleeve.
By arranging latch assembly on original alignment pin, substitute binding clasp of the prior art, apply to clamp the chucking power of part to be measured by the body of alignment pin to set pin sleeve and part to be measured is clamped, avoid when limited space, independent binding clasp or binding clasp affect the problem of manual detection parts to need inconvenience to arrange, thus improve the efficiency of detection.
Fig. 1 to 6 shows that exemplary embodiments of the present utility model, spline locking positioning pin mechanism include the set pin sleeve 2 being arranged at cubing and be arranged in the alignment pin 1 of set pin sleeve；Alignment pin 1 includes body 10 and latch assembly.
Wherein, latch assembly includes tie down screw 11, set lever 12 and fixing screw 13；
Body 10 offers the first through hole 14；Set lever 12 offers the second through hole 15 and fixing threaded hole 16；Tie down screw 11 forms key pin towards the first end 11a of set lever, offers screw thread (not shown) towards the second end 11b of set pin sleeve 2；Set pin sleeve 2 offers third through-hole 21, third through-hole 21 mates with the second end 11b screw thread of tie down screw 11 away from the inner wall shape of one end of body 10, for fixing the second end 11b screw thread of tie down screw 11, so that will not move axially relative to set pin sleeve 2 when tie down screw 11 is locked；Second through hole 15 inwall of set lever 12 and the first end 11a key pin outer peripheral edge of tie down screw 11 arrange and match, and set lever 12 can move along tie down screw 11 bearing of trend；Fixing screw 13 is arranged in fixing threaded hole 16, for providing pressure, so that after fixing screw 13 screws, set lever 12 will not move axially relative to tie down screw 11 and rotate to the first end 11a keyway of tie down screw 11；
When needs are locked, first tie down screw 11 is arranged in the receiving intracavity being made up of first through hole the 14, second through hole 15 and third through-hole 21；Tightening screw 13, ensureing that set lever 12 will not move axially relative to tie down screw 11 and rotate, then rotational lock handle 12 makes it drive body 10 to move towards set pin sleeve 2, clamps part 3 to be measured and clamps, thus arrange, it is achieved that the locking function of spline locking positioning pin mechanism.In order to increase frictional force, convenient rotation, set lever 12 outer peripheral edge is additionally provided with roller flower (not shown).
Body 10 is provided with spline end 23 and positioning end 17, in this enforcement towards one end of set pin sleeve 2
In example, spline end 23 is preferably key pin, and positioning end 17 is preferably rhombus cone；The third through-hole 21 of set pin sleeve 2 is formed with receiving spline end 23 towards one end inwall of body 10, and the keyway 22 mated with spline end 23, the inwall of keyway 22 is formed with the locating surface mated with spline end 23 outer peripheral edge, so that body 10 will not rotate relative to set pin sleeve 2；The third through-hole of set pin sleeve 2 is also formed with accommodating the locating slot 24 of positioning end 17 inside one end of body 10；Spline end 23 and the positioning end 17 of body 10 are worn the third through-hole 21 into set pin sleeve 2, owing to the keyway 22 of set pin sleeve 2 and the spline end 23 of body 10 match, so that body 10 will not rotate relative to set pin sleeve, positioning end also can position the hole site of auto parts and components, thus achieves spline and the positioning function of spline locking positioning pin mechanism.The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done, should be included within the scope of this utility model protection.
