Abstract

Disclosed is a bouncing degree detector, comprising a locating lever, a measuring tool body fixedly arranged upon the locating lever, and a dial indicator fixedly arranged upon the measuring tool body, wherein the top end of the locating lever is provided with a connecting shaft eccentric to the locating lever, with the eccentricity between the locating lever and the connecting shaft being 1; the measuring tool body is fixedly arranged upon the locating lever via the eccentric connecting shaft; the measuring tool body is provided with a pin I used for fixing the measuring tool body upon the locating lever connecting shaft; the connecting shaft is symmetrically provided with an Alpha plane and a Beta plane in the axial direction, with the pin tightly against the Alpha plane or the Beta plane of the connecting shaft; and the measuring tool body is further provided with a pin II for fixing the dial indicator. The bouncing degree detector of the utility model is utilized to measure the bouncing degree of same benchmark of two step-hole pairs, which substantially improves the measuring speed, raises the working efficiency, solves the problem of making multiple locating levers, and decreases the cost of making the measuring tool.

Description

The beating degree pick-up unit

Technical field

The utility model relates to a kind of pick-up unit of mechanical part, particularly a kind of device that is used for machines machining hole beating degree.

Background technology

Round glitch detection appearance is mainly adopted in the measurement of beating degree, surveys the beating degree of appearance or endoporus through the dial gauge contact.Measure two holes at present and need measure with the different measurers of two covers the beating degree of same benchmark, the beating degree in a hole of every survey all will be selected the suitable measurer of backstay, surveys the beating degree in two holes and then will select twice measurer.The backstay size classification of every suit measurer is more, so every cover measurer all can be made the backstay of a series of sizes, owing to make the precision height of backstay, quantity is many, has therefore increased the cost of making measurer greatly; And change measurer repeatedly, greatly reduce detection efficiency.

To above-mentioned deficiency, a kind of new beating degree pick-up unit need be provided, when reducing the cost of making measurer, improve the speed of two holes of measuring greatly to same benchmark beating degree.

The utility model content

In view of this, the purpose of the utility model provides a kind of beating degree pick-up unit, when reducing the cost of making measurer, improves the speed of two holes to same benchmark beating degree of measuring greatly.

The purpose of the utility model realizes through following technical scheme: a kind of beating degree pick-up unit; Comprise backstay, be fixedly installed on the measuring on the backstay and be fixedly installed on the dial gauge on the measuring; The top of said backstay is provided with and the eccentric coupling shaft of backstay; Eccentric throw between backstay and the coupling shaft is l, and measuring is fixedly installed on the backstay through eccentric coupling shaft.

Further, be provided for being fixed in the pin I on the backstay coupling shaft on the said measuring;

Further, be symmetrical set the α plane and the βPing Mian of two symmetries on the coupling shaft vertically, α plane or βPing Mian that pin presses closer at coupling shaft;

Further, also be provided for the fixedly pin II of dial gauge on the said measuring.

The beneficial effect of the utility model: when the beating degree pick-up unit of employing the utility model is measured the beating degree of same benchmark two shoulder holes, improved measuring speed greatly, improved work efficiency; And overcome the shortcoming of making many backstays, reduce the measurer cost of manufacture.

Embodiment

Fig. 1 is the structural representation of the utility model; Fig. 2 is the vertical view of the utility model; Fig. 3 is the user mode figure that measures when the D1 hole is to benchmark A beating degree in the shoulder hole; Fig. 4 is the P portion enlarged drawing among Fig. 3; Fig. 5 is the user mode figure that measures when the D2 hole is to benchmark A beating degree in the shoulder hole; Fig. 6 is the M portion enlarged drawing among Fig. 5.As shown in the figure: a kind of beating degree pick-up unit of present embodiment; Comprise backstay 1, be fixedly installed on the measuring 2 on the backstay and be fixedly installed on the dial gauge 3 on the measuring; The top of said backstay is provided with and the eccentric coupling shaft 1a of backstay; Eccentric throw between backstay and the coupling shaft is l, and measuring is fixedly installed on the backstay through eccentric coupling shaft; In the present embodiment, be provided for being fixed in the pin I 4 on the backstay coupling shaft on the said measuring; Be symmetrical set the α plane and the βPing Mian of two symmetries on the coupling shaft vertically, α plane or βPing Mian that pin 4 presses closer at coupling shaft; Also be provided for the fixedly pin II 5 of dial gauge 3 on the said measuring 2.

Method of application is: after the beating degree pick-up unit of the utility model is assembled; Utilize the eccentric structure on backstay 1 and the measuring 2 can adjust the distance between backstay 1 center to the contact of dial gauge 3, to reach with same measurer to measuring with benchmark shoulder hole beating degree.As shown in Figure 3, energy measurement D1 hole was to the beating degree of diagram benchmark A when screw 4 was compressed the α face on the backstay 1; After the beating degree that measures D1, as shown in Figure 5, unclamp screw 4, measuring 3 around backstay 1 rotation, until the β face that screw 4 points on the backstay 1, is tightened screw 4 and compressed the β face on the backstay, measure the beating degree of D2 hole to benchmark A.

Adopt the transfer degree pick-up unit of the utility model to have improved measuring speed greatly, improved work efficiency to reach with the purpose of same measurer to measuring with benchmark shoulder hole beating degree; And overcome the shortcoming of making many backstays, reduce the measurer cost of manufacture.
