Description
Technical field
The present invention relates to a kind of bearing measuring mechanism, be specially a kind of bearing protrusion measuring sheet mechanism diligently.
Background technology
Heart sheet mechanism is the measurement annex that is used for the bearing end-play or measures bearing protrusion amount, and at bearing industry, when bearing end-play or survey bearing protrusion amount, indicator must be surveyed on axial line as shown in Figure 6.
Because the axial line position of dead eye is a hollow, bearing industry generally adopts like Fig. 6 and heart sheet shown in Figure 7, is characterized in that size d gets the brearing bore size and subtracts tolerance; Guaranteeing to let heart sheet put into brearing bore plays the role of positioning; Size d2 gets the external diameter size of bearing inner race, as long as this heart sheet is placed in the axis hole during use, instrument head is surveyed at the axial line a of heart sheet point; Because the axial line a point of heart sheet overlaps with the axial line of bearing; Shown in the thought-read sheet a data of ordering be exactly the actual value of bearing end-play or protrusion amount, but along with the raising measuring accuracy of bearing accuracy also improves constantly, especially protrusion measuring requires to be the tolerance of 2um; Heart sheet originally all is that car adds part, and precision is not high enough.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of bearing protrusion measuring sheet mechanism diligently is provided.
According to technical scheme provided by the invention, said bearing protrusion measuring is sheet mechanism diligently, and it comprises separable heart sheet body and centering body, and heart sheet body is connected through joint bolt with the centering body and is one; Described heart sheet body is the cylinder bodily form with the centering body; On the top end face of heart sheet body, offer circular end face depression around its axis; On the bottom face of heart sheet body, offer columned centering depression around its axis; The bottom face of the heart sheet body outside the centering depression offers refuse chute, and described refuse chute is communicated with the centering depression, offers intentionally sheet mounting hole at the bottom face shaft core position of heart sheet body; Shaft core position at the centering body offers the centering mounting hole, and the centering mounting hole body coaxial be connected is one with heart sheet body with centering with the interior joint bolt that screws in of heart sheet mounting hole;
The bottom face of the top end face of said heart sheet body and heart sheet body is the flat surface grinding.
The degree of depth of said refuse chute is less than the degree of depth of centering depression.Said refuse chute is radially on the bottom face of heart sheet body to be offered.
Advantage such as simple in structure, easy to manufacture, easy to use and measurement data that the present invention has is accurate.

Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure, this bearing protrusion measuring is sheet mechanism diligently, and it comprises separable heart sheet body 1 and centering body 2, and heart sheet body 1 is connected through joint bolt 3 with centering body 2 and is one; Described heart sheet body 1 is the cylinder bodily form with centering body 2; On the top end face of heart sheet body 1, offer circular end face depression 1.1 around its axis; On the bottom face of heart sheet body 1, offer columned centering depression 1.2 around its axis; Bottom face at the heart sheet body 1 in centering depression 1.2 outsides offers refuse chute 1.3, and described refuse chute 1.3 is communicated with centering depression 1.2, offers at the bottom face shaft core position of heart sheet body 1 and has the inclination sheet mounting hole 1.4; Shaft core position at centering body 2 offers centering mounting hole 2.1, and centering mounting hole 2.1 body 2 coaxial are connected is one with heart sheet body 1 with centering with the heart sheet mounting hole 1.4 interior joint bolts 3 that screw in.
The degree of depth of said refuse chute 1.3 is less than the degree of depth of centering depression 1.2.Said refuse chute 1.3 is radially on the bottom face of heart sheet body 1 to be offered.
Heart sheet of the present invention mechanism is made up of separable heart sheet body 1 and 2 two of bodies of centering, separable fundamental purpose be measurement face (top end face of heart sheet body 1) and reference field (bottom face of heart sheet body 1) but measuring accuracy is guaranteed in flat surface grindings all.Top end face at heart sheet body 1 centers on toroidal cavity of its axis car, can reduce top surface of contact like this, helps guaranteeing the flatness of heart sheet.Since car a toroidal cavity, so be the small cylinder at heart sheet body 1 center, find the measuring center point when helping measuring at axis part, to open several refuse chutes 1.3 at the bottom face of heart sheet body 1.The major function that refuse chute 1.3 is set is to reduce the surface of contact of heart sheet and workpiece; Help guaranteeing the flatness of heart sheet body 1; When measuring, rotate heart sheet body 1 simultaneously, the rubbish of surface of the work can be gone to refuse chute and go for 1.3 li, thereby reduces cleanliness to influence of measurement error.
After heart sheet body 1 tightened up through joint bolt 3 with centering body 2, use principle was identical with the principle of old structural drawing, but measuring accuracy can bring up to 0.001.
