Abstract
The utility model relates to a high precision involute spline distance-over-bar flexible measurement apparatus, and belongs to measurement apparatuses for machined parts examination clamps. A stop pin is fixedly connected with a machine base. A linear bearing is connected with the machine base in a sliding mode. The linear bearing is in differential slip with a sleeve. A transmission bar and the sleeve are in sliding connection. The sleeve is in pin junction with a pin. A measurement head is in threaded connection with the sleeve. A dial gauge is in threaded connection with the sleeve. A handle is in threaded connection with a cam. A spring is positioned between the transmission bar and the measurement head. The high precision involute spline distance-over-bar flexible measurement apparatus of the utility model is advantageous in that: the high precision involute spline distance-over-bar flexible measurement apparatus is novel in structure, and can carry out measurement on external splines accurately and rapidly and determine the distances-over-bar of the external splines; the efficiency and the accuracy of on-site measurement are guaranteed; and in measurement, the cam and the linear bearing are employed to make the measurement to be very accurate and the usage to be very labor saving.
Description
Technical field
The utility model belongs to the measurement mechanism of machine-made spares inspection jig.
Background technology
Measurement mechanism is ingredient very important in inspection jig, and reading of final measurement is to rely on it to complete.The selection of the precision of measurement mechanism self and measurement point position all directly affects measurement result, and the standard metrology tool in inspection jig design is dial indicator.Measuring the accuracy of transmitting is to reduce most critical one ring that measuring error improves measuring accuracy, and it is the problem that will consider in the middle of design equally that indicating value easy to use reads simple and clear.
In the design of machine-made spares inspection jig, while relating to the measurement of high precision involute spline, conventionally adopt chute-type, square groove formula measuring mechanism at present, this measuring mechanism is easy to wear, slide dumb, the spring force that cam handle need to overcome is large, is not laborsaving especially.
Summary of the invention
The utility model provides a kind of high precision involute spline Kua Bangju flexible measuring mechanism, to solve easy to wear that existing measuring mechanism exists, slides dumb, and the spring force that cam handle need to overcome is large, is not special labour-saving problem.
The technical solution of the utility model is: backing pin is fixedly connected with support, linear bearing and support are slidably connected, linear bearing and sleeve differential sliding, drive link and sleeve are slidably connected, sleeve is connected with finger pin, and gauge head is connected with bush whorl, and indicating gauge is connected with bush whorl, handle is threaded with cam, and spring is between drive link and gauge head.
The utility model has the advantage of: novel structure, can to male splines, measure quickly and accurately, determine male splines across excellent distance, guaranteed efficiency and the accuracy of in-site measurement, during measurement, adopt cam and linear bearing to make measurement very accurate, use very laborsaving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model body overhead cam and handle portion.
In figure, support 1, gauge head 2, spring 3, linear bearing 4, sleeve 5, drive link 6, backing pin 7, indicating gauge 8, finger 9, cam 10, handle 11.
Embodiment
Backing pin 7 is fixedly connected with support 1, linear bearing 4 is slidably connected with support 1, linear bearing 4 and sleeve 5 differential slidings, drive link 6 is slidably connected with sleeve 5, sleeve 5 is connected with finger 9 pins, and gauge head 2 is threaded with sleeve 5, and indicating gauge 8 is threaded with sleeve 5, handle 11 is threaded with cam 10, and spring 3 is between drive link and gauge head.
Pull backward handle 11 and stir finger 9 and move, finger 9 band sleeves 5 and gauge head 2 and indicating gauge 8 move, and spring 3, in compressive state, is oppositely stirred handle 11, by backing pin 7, and drive link 6, spring 3 resets measuring mechanism, in measuring state.
