Abstract
The utility model relates to a preloaded disk spring device which is one of most important parts in an air flotation coordinate measuring machine. A preload air bearing has relative resilience to the change of supplying air. If a disk spring is not arranged in the preload air bearing, the stability of each rigid body in the process of the dynamic measurement of the air flotation coordinate measuring machine is not ensured and the precision of measurement is reduced. The preloaded disk spring device comprises an air bearing 2, a disk spring 1 which is arranged on the air bearing 2, an elastic washer 3 which is pressed on the disk spring 1, and supporting bolts 4 which are respectively connected with the elastic washer 3, wherein the supporting bolts 4 are arranged in a nut 5 and a lining sleeve 6 which are arranged in a rigidity connector 7. The utility model is used for the air flotation air bearing of the coordinate measuring machine.
Description
Technical field:
The utility model relates to a kind of belleville spring device that preloads.
Background technique:
Belleville spring is one of most important part in the air supporting coordinate measuring machine, the pneumatic bearing that process preloads has corresponding spring-back force to the variation of air feed, if do not have belleville spring in the pneumatic bearing that preloads, just can not guarantee the stability of each rigid body in the air supporting coordinate measuring machine dynamic measurement process, reduce the degree of accuracy of measuring.
Summary of the invention:
The purpose of this utility model provide a kind of be used for coordinate measuring machine air supporting pneumatic bearing preload the belleville spring device.
Above-mentioned purpose realizes by following technological scheme:
Preload the belleville spring device, its composition comprises: air-bearing, described air-bearing is provided with belleville spring, be pressed with elastic washer on the described belleville spring, described elastic washer and stay bolt link, described stay bolt is installed in nut and the lining, and described nut and lining are contained in the rigid joint part.
This technological scheme has following beneficial effect:
1. belleville spring is one of most important part in the air supporting coordinate measuring machine, the air-bearing that process preloads has corresponding spring-back force to the variation of air feed, and belleville spring is a kind of standardized element of simple shape, and be to use the steel plate drawing, profile is the truncated cone shape, so have buffering, shock-absorbing, stored energy and become the effect that rigidity realizes transient equiliblium, thereby can guarantee the stability of each rigid body in the air supporting coordinate measuring machine dynamic measurement process, guarantee the motion pliability and the sensitivity of each air-float guide rail, improve the degree of accuracy of measuring.
2. simple in structure, easy to operate, the good manufacturability of the utility model.
Description of drawings: accompanying drawing 1 is the structural representation of this product.
Embodiment:
Embodiment 1:
Preload the belleville spring device, its composition comprises: air-bearing 2, described air-bearing 2 is provided with belleville spring 1, be pressed with elastic washer 3 on the described belleville spring 1, described elastic washer 3 links with stay bolt 4, described stay bolt 4 is installed in nut 5 and the lining 6, and described nut 5 and lining 6 are contained in the rigid joint part 7.
Embodiment 2:
The above-mentioned belleville spring device that preloads, its working principle: form pressure air film 8 (as Fig. 1) when pressurized air enters air-bearing 2 by the throttling pore on the air-bearing 2 (or throttling groove), when rigid joint part 7 relative guide rails 9 are realized frictionless motion, then the belleville spring in preloading air-bearing 21 is subjected to from the thrust load under the effect of pressure air film, so awl base angle, the cross section of belleville spring 1 reduces, belleville spring 1 produces axial deformation, its axial dimension diminishes, thereby elastic energy that produces and air supporting pressure keep transient equiliblium, making the air-film thickness between its surface that guarantees air-bearing 2 relative guide rails 9 is 1/2 of belleville spring 1 axial deformation, guarantee the stiff stability of each rigid body in the coordinate measuring machine dynamic measurement process, strengthened the dynamic stability of system.
Claims (1)
1. one kind preloads the belleville spring device, its composition comprises: air-bearing, it is characterized in that: described air-bearing is provided with belleville spring, be pressed with elastic washer on the described belleville spring, described elastic washer and stay bolt link, described stay bolt is installed in nut and the lining, and described nut and lining are contained in the rigid joint part.
