Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Example 1

Referring to fig. 2, fig. 2 is a top view of a large glass chuck for optical coating according to an embodiment of the present invention.

This chuck includes internal dial, outward turning disc and clamping jaw at least, internal dial activity nestification is in outward turning disc, the equidistant rotation of edge of internal dial is followed to the one end of clamping jaw connects the setting, the radial sliding connection setting of outward turning disc is followed to the other end of clamping jaw. In one embodiment of the embodiment, the number of the clamping jaws is four, so that the clamping of the large square glass is facilitated; besides the number of the clamping jaws is set to be four, the clamping jaws can be set to be one, two, three or more, and the description is omitted.

The chuck provided by the embodiment realizes variable caliber through the following operation modes: the rotating inner rotary disc is rotated, the clamping jaws and the rotating inner rotary disc are rotatably connected with one end of the rotating inner rotary disc and are driven to rotate when the inner rotary disc rotates, the self rotates with the connecting end of the rotating inner rotary disc, the clamping jaws and the other end of the radial sliding connection of the outer rotary disc rotate when the inner rotary disc rotates, the clamping jaws slide along the radial direction of the outer rotary disc, so that the calibers formed by limiting the clamping jaws are changed, for example, when the inner rotary disc rotates positively, the calibers are reduced, when the inner rotary disc rotates reversely, the calibers are increased, and the calibers are adjusted. It should be noted that, compared with the related art in which the chuck is manually adjusted, the chuck provided in the present embodiment is used for clamping large glass, so that high clamping stability can be provided, and each clamping jaw does not need to be adjusted independently, so that the operation is simple, manpower can be effectively saved, and the wiping efficiency is improved.
