Embodiment Construction

[0017] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 , figure 2 The clamping jaws shown for easy replacement include: a three-claw base 1 fixedly connected to the base of the optical surveying instrument, a three-claw head 2 located above the three-claw base 1, a three-claw head 2 and a three-claw base 1 Detachable connection. The three-claw head 2 includes: a rotating rod 23, a first ring 21 and a second ring 22 positioned outside the rotating rod; A fixed thread is provided; an annular protrusion 24 is provided on the rotating rod 23 .

[0019] The three-claw base 1 is provided with a groove for placing the three-claw head 2, and the top of the groove is provided with an internal thread that cooperates with the fixed thread. When installing, the first ring 21 and the second ring 22 are sleeved on the rotating rod 23 outside, then put the three-claw head 2 into...

Abstract

The invention discloses a clamping jaw convenient to replace. The clamping jaw convenient to replace comprises a three-jaw base fixedly connected with a substrate, and a three-jaw head positioned on the three-jaw base. The clamping jaw convenient to replace is characterized in that the three-jaw head is detachably connected with the three-jaw base; the three-jaw head comprises a rotating lever, and a first ring and a second ring positioned on the outer side of the rotating lever; the first ring is fixedly connected with the second ring; the periphery of the first ring is provided with fixing screw threads; the rotating lever is provided with an annular boss. The clamping jaw convenient to replace has the beneficial effects that the three-jaw head is convenient to take down and replace; the second ring is a rubber ring, the connection of the three-jaw head and the three-jaw base is increased by the deformation of the second ring; thus, looseness is not generated when the clamping jaw is used for clamping optical elements and instruments.

Description

technical field [0001] The invention relates to a chuck structure of an optical component, in particular to a snap-in claw for easy replacement in a three-jaw chuck. Background technique [0002] The three-jaw chuck is composed of three-jaw bases, snap-in claws and other components. In optical measurement, the radial movement of the three snap-in claws evenly distributed on the three-jaw chuck can be used to clamp and position the workpiece on the three-jaw chuck. on optical mapping instruments. The three-jaw chuck has been used for a long time. With the wear of the chuck, the three jaws will appear bell-shaped, and the three jaws will gradually deviate from the center of the three-jaw chuck, which will affect the clamping of optical parts and instruments. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a snap-in claw that is easy to replace. [0004] In order to achieve the above o...
