Summary of the invention
Goal of the invention of the present utility model provides a kind of simple, convenient and practical, can locate cubing with respect to the calibrating technological datum hole of the form and position tolerance of hair basal plane location dimension in fast detecting product technological datum hole.
Technical solution of the present utility model is: the through hole corresponding with position to be detected arranged on the cubing body, lining is housed on the through hole; Lever is loaded on the body lower end through balance pivot, and the two ends of lever have gauge head A, gauge head B respectively, and the gauge head A of lever places the cover intracoelomic cavity; Dial gauge is equipped with on body top, the sounding rod of dial gauge is perpendicular to the body central axis, the sounding rod of dial gauge stretches into the cover intracoelomic cavity and pushes up mutually with the gauge head A of lever, is provided with the spring that the gauge head A that promotes an end on sounding rod that the lever rotation makes dial gauge and the lever contacts in the body.
Said cubing body is provided with round register pin, rhombus pin.
Said lining and body are clearance fit.
Said body is provided with the screw that is used to withstand lever, prevents any rotation of lever.
Said body is provided with the lock-screw that is used for after dial gauge is pressed into rod gear and adjusts its locking.
On the said body handle is housed.
The utility model also comprises a calibration cover that is used for dial gauge school zero.
That the utility model compared with prior art has is easy to operate, simple in structure, precision is reliable, easy to manufacture, cost is low, be easy to characteristics such as production.Solved on the product processing line problem, saved detection time, improved work efficiency, can be used widely in respect to the strict detection of product hair basal plane in the technological datum hole to production quality control.

Embodiment
Among Fig. 1, Fig. 2, cubing body 1 is provided with round register pin 4, rhombus pin 2, the through hole corresponding with position to be detected, and lining 5 is housed on the through hole, and rod gear 3 is by contacting the purpose that reaches detection with product hair basal plane 18 in the lining 5 that inserts cubing body 1.The utility model in use, rod gear 3 is a clearance fit with lining 5.
Among Fig. 3, Fig. 4, rod gear 3 is made up of body 8, handle 7, lever 16, balance pivot 15, gauge head A14, gauge head B17, dial gauge 11, spring 13, lock-screw 10, holding screw 12 and screw 9.Lever 16 is loaded on body 8 lower ends through balance pivot 15, the two ends of lever 16 have gauge head A14, gauge head B 17 respectively, the gauge head A14 of lever 16 places body 8 inner chambers, the gauge head B17 of lever 16 inserts calibration cover 6 and contacts with hole wall, dial gauge 11 is equipped with on body 8 tops, the sounding rod of dial gauge 11 is perpendicular to body 8 central axis, the sounding rod of dial gauge 11 stretches into body 8 inner chambers and pushes up mutually with the gauge head A14 of lever 16, and dial gauge 11 is adjusted the back and locked with lock-screw 10 in being pressed into rod gear 3.Be provided with in the body 8 and promote the spring 13 that gauge head A14 that lever 16 rotates an end on the sounding rod that makes dial gauge 11 and the lever 16 contacts, handle 7 is arranged on the body 8, left-right rotation handle 7 makes the gauge head B17 on the lever 16 contact with product hair basal plane 18.The gauge head A14 at two ends, gauge head B17 contact with product hair basal plane 18 with the sounding rod of dial gauge 11 respectively by balance pivot 15 rotating levers 16 on the lever 16, obtain the reading of dial gauge 11.Lever 16 is promoted by spring 13, and spring 13 back are blocked with holding screw 12, and lever 16 relies on the top of screw 9 to withstand behind and prevents that lever 16 from rotating arbitrarily.At every turn should school zero before formal measurement products, rod gear 3 is placed on makes gauge head B17 contact hole wall in the calibration cover 6, the reading of adjusting dial gauge 11 is zero.
Design theory of the present utility model is a product hair basal plane to the distance of the round register pin of cubing is theoretical size.During use, in the time of before formal measurement products, should being pressed into dial gauge 11 in the rod gear 3 at every turn, the sounding rod of dial gauge will have the decrement about 1mm, rod gear 3 is placed on to make gauge head B17 contact hole wall in the calibration cover 6 then, and the reading of adjusting dial gauge 11 is zero.During inspection cubing body 1 is put into the technological datum hole of product by 2 register pins, the lower plane of cubing body 1 and the machined surface of product are adjacent to, then rod gear 3 is inserted in the lining 5 corresponding with detected position, turning handle 7, when the gauge head B17 of rod gear 3 contacted with product hair basal plane 18, the minimal difference that reads dial gauge 11 left and right horizontal positions was the error that product size departs from.
