Specific embodiment
The utility model is described in detail with reference to the accompanying drawing, Fig. 1 shows pole piece material strip in the utility model
A kind of structural schematic diagram of embodiment of length measuring system, is mainly made of carrying roller 1 and encoder 2.Above-mentioned carrying roller 1 wraps
Include the support shaft 11 and roller 12 for being fixed on backboard.Roller 12 is under the frictional force drives of pole piece material strip relative to support shaft 11
Rotate in a circumferential direction movement.Above-mentioned encoder 2 includes magnetic railings ruler 21 and reading head 22, wherein magnetic railings ruler 21 is fixed on roller 12
End face, reading head 22 are fixed on support shaft 11 by support base 3, so, magnetic railings ruler 21 be not easy to contact with pole piece material strip and
Cause to wear, in addition, the axial dimension of roller 12 need not be extended, convenient for reducing rotary inertia by light-weight design, reduces pole
Opposite slippage of the piece material strip relative to roller 12, to improve measurement accuracy.In addition to the advantages indicated above, in traditional design
Scheme, the reference for installation of reading head 22 are backboard, the accumulation being easy to cause error, and in this design scheme, reading head 22
Reference for installation is the support shaft 11 with 12 arranged concentric of roller, thus, convenient for improving installation accuracy, and it is convenient for the maintenance in later period.
In order to further prevent magnetic railings ruler 21 to be damaged and dust-proof needs, protective plate 16, edge can also added
The axial direction of roller 12 extends a distance into (as shown in Figure 2).
Furthermore the contactless position encoder for measuring to pole piece material strip length is above-mentioned in addition to that can use
Encoder 2 can also select grating etc. according to the actual situation.
Herein it should be noted that in order to ensure measurement accuracy, the phase of strict control reading head 22 with magnetic railings ruler 21 is needed
Location error, especially reading head 22 are preferably controlled at a distance from magnetic railings ruler 21 in 0.1~0.8mm, and the two rock tolerance,
At ± 2 °, in addition pitching tolerance and rolling pendulum tolerance control, it is also necessary to be controlled (such as the opposite depth of parallelism and verticality
Shown in Fig. 4).In addition to this, during reading head 22 are installed, the mounting surface and support shaft 11 of control support base 3 are also needed
The depth of parallelism, must control in 0.3.
In order to reduce the rotary inertia of roller 12 as much as possible, the specific structure of carrying roller 1 can refer to be designed as follows: rolling
Cylinder 12 is in thin-wall circular tubular, is made by carbon fiber, and be fixed with the transition piece 14 of aluminum alloy material at its both ends.In addition,
There are two bearing 13 in support shaft 11, just corresponding to the setting of above-mentioned 14 position of transition piece, one of bearing 13 passes through the shaft shoulder
111 carry out abutting against fixation, another bearing 13 is compressed (as shown in Figure 2) by gland 15.In addition, in order to further drop
Low rotor inertia can also offer the lightening hole being evenly distributed on transition piece 14.
As the modification of above-mentioned 2 mounting means of encoder, magnetic railings ruler 21 can also be fixed in support shaft 11, correspondingly,
Reading head 22 is fixed on the end face of roller 12.
Finally, the structure that Fig. 3 shows pole piece material strip length measuring system another embodiment in the utility model is shown
Intention, reading head 22 and magnetic railings ruler 21 can also be set to the free end of support shaft 11, and the specific actual conditions of design structure carry out
Change.
