Specific embodiment
The utility model is described in further detail below in conjunction with Figure of description and specific embodiment.
As shown in Fig. 2, the measuring device of the interior cold hole actual lead of the present embodiment includes workbench 2,3 and of bar support base
Two groups of measurement components 4 at 3 both ends of bar support base are divided into, measurement component 4 includes bracket 41, angle dial 42, pointer 43
With positioning pin 44, bracket 41 is placed on workbench 2, and angle dial 42 is liftable to be set on bracket 41, and pointer 43 can be around
42 center rotating of angle dial is set on angle dial 42, and positioning pin 44 can be set along what angle dial 42 moved radially
In on pointer 43, positioning pin 44 can cooperate with interior cold hole 11, and bar support base 3 is equipped with and is used to support interior cold bar 1 and makes interior cold
The V-shaped groove 31 parallel with the horizontal plane of workbench 2 of bar 1, interior cold hole 11 are located on interior cold bar 1, angle dial 42 and work
Make the horizontal plane of platform 2, the axis of positioning pin 44 is vertical with angle dial 42.
In the present embodiment, pointer 43 is equipped with the sliding block 45 that can be radially slided, and positioning pin 44 is set on sliding block 45, mobile to slide
The height of positioning pin 44 is adjusted in block 45.Pointer 43 is mounted on angle dial 42 by pin shaft 46, and pointer is around 4 phase of pin shaft
Angle dial 42 is rotated.The both ends of the surface of the bar support base 3 also horizontal plane with workbench 2.
When specifically being measured using the measuring device of the utility model, the outer screw pitch of interior cold bar 1 is precomputed
Periodicity N, calculation method are as follows: with the overall length L of bar 1 cold in vernier caliper measurement, according to interior cold 11 theory lead P0 (factory of hole
Family provide) calculate N, N=L/P0, as a result only give up to enter, the measurement method method specifically includes the following steps:
(1) cold hole 11 in optional one of cold 1 one end face of bar, is labeled as hole A, pours into compressed air including, finds out internally
The interior cold hole 11 that cold 1 other end of bar has gas to flow out, is labeled as hole A ', and A-A ' constitutes an inner cooling path；
(2) interior cold bar 1 is placed on V-shaped groove 31, rotating interior cold bar 1 makes hole A be approximately at highest point, rotation and hole
The corresponding pointer 43 in the end A is overlapped it (such as Fig. 4) with 0 ° of line on angle dial 42, adjusts 44 height of positioning pin and (passes through movement
Sliding block 45 adjusts the height of positioning pin 44) it is aligned positioning pin 44 with the hole center A, then positioning pin 44 is caught in hole A (as schemed
In 3 shown in the part b) in；
(3) pointer 43 corresponding with the end hole A ' is rotated, while adjusting the height of the end positioning pin 44, makes positioning pin 44 and hole
The alignment of the center A ', translating bracket 41 are caught in positioning pin 44 in hole A ' (as shown in the part a in Fig. 3), record the end pointer at this time
β (as shown in Figure 5) is read on angle dial 42 corresponding to 43；
(4) set the deflection angle in interior cold hole 11 as β, by P '/360 formula L=N*P '+β *, can obtain P '=L/ (N+ β/
360), L, N, β are brought into P '=L/ (β/360 N+), finds out P ', P ' is the actual lead in interior cold hole 11.
In the present embodiment, in step (2), before adjusting 44 height of positioning pin and being aligned positioning pin 44 with the hole center A, first
According to the height of interior cold bar 1, then the preliminary height (coarse adjustment) for adjusting angle dial 42 on bracket 41 is adjusting positioning
The height (fine tuning) of pin 44.After adjusting 44 height of positioning pin and being aligned positioning pin 44 with the hole center A, interior cold bar 1 is translated
And fine rotation, it is caught in positioning pin 44 in the A of hole.In addition to the present embodiment, bracket 42 can also be moved, inserts positioning pin 44 actively
Enter hole A.
The measuring device of the interior cold hole actual lead of the utility model, according to formula P '=L/ (β/360 N+), using two groups
The deflection angle that measurement component 4 measures interior cold hole 11 is β, to calculate actual lead P ', can fast and accurately be measured interior
The actual lead in cold hole corrects deviation, interior cold hole is avoided to be worn through and waste product occur.And the prior art is unable to measure interior cold hole
Actual lead P ' when grinding, can only be subject to the theoretical lead of bar supplier offer, therefore in actual production, interior cold hole is real
Border lead and theoretical lead always have some deviations, if deviation is excessive, will lead to interior cold hole and are worn through, drill bit is scrapped.
