Aforesaid a kind of new gear pitch error pick-up unit is characterized in that described column is provided with screw thread, and described sensor bracket is installed on the column.
The beneficial effects of the utility model are:
1, drives gear to be measured and do the rotation of accurate constant speed because the utility model is provided with stepper motor, add and utilize highly sensitive displacement transducer to catch the tooth pitch deviation data, so requirement of this pick-up unit coincidence measurement precision, efficiency of measurement and economy, The hardware design is succinct, the software section modular design meets the design concept of modern electronic product.
2, because the utility model only need be provided with relevant parameters at different gears and just can finish whole surveying work automatically, solved big, the inefficient problem of traditional measurement instrument workload, so under the prerequisite that guarantees measuring accuracy, improve measuring speed greatly, can satisfy enterprise's production development needs.
3, because the utility model has adopted the flexible design mode of replaceable axle, be fit to measure different in the gear of external diameters, so measurement range of the present utility model is wide, and can realize more test function add other measurement module in the future.
4, because the utility model adopts the Computer Analysis deal with data, so can select to preserve the measurement data that meets specific format easily.
[description of drawings]
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the axis side view that waits of the present utility model;
Fig. 3 is a software program flow chart of the present utility model.
[embodiment]
As shown in the figure, a kind of new gear pitch error pick-up unit, it is made up of bearing assembly 1, clamping assembly 2 and measurement assembly 3; Described bearing assembly comprises base 101, and being installed in above the base 101 is can parallel mobile slide plate 102, and tailstock 103 and bearing seat 104 are installed on the slide plate 102.In top 105 cavitys that are installed in above the tailstock 103.Axle 106 is inserted in the dead eye of bearing seat 104, gear to be measured is inserted in the axle 106, and gear to be measured is fixed by gear check nut 204.
Motor frame 107 is installed, fastening with standard bolt.Stepper motor 4 passes motor frame 107 macropores and inserts axle 106 right-hand members, adjusts axle 106 angles, is screwed into clamp-screw 5, can be affixed stepper motor 4 and axle 106.
