Problems solved by technology

Although the fixture is simple and lightweight, it is flexible and convenient to operate, and has high repeat positioning accuracy, which ensures the precision of mold spray welding. During the clamping process, it is necessary to constantly adjust the placement angle of the large-size neodymium glass piece
[0004] In the prior art, when the large-size neodymium glass sheet is used to detect the transmitted wavefront error, the stage is usually used to place the large-size neodymium glass sheet, and manual handling is used to realize the detection clamping and moving transfer, so it is impossible to guarantee the large-size The neodymium glass sheet is securely clamped and at the same time realizes the convenient placement angle adjustment and mobile transfer of large-size neodymium glass sheets

Embodiment 1

[0029]A large-size neodymium glass plate transmission wavefront error detection fixture includes a base 19, a base turntable 14 is arranged on the top surface of the base 19, and the base turntable 14 can rotate freely on the base 19. The connection mode between the base 19 and the base turntable 14 is: the base 19 and the connection pins above the base 19 are fixedly connected by screws, the base turntable 14 is sleeved on the connection pins and positioned by the shoulders of the connection pins, and the base turntable 14 The aperture is slightly larger than the diameter of the connecting pin, so the base rotating disk 14 can rotate freely around the axis of the connecting pin. In addition, a thrust bearing can also be set between the base rotating disk 14 and the base 19, and the distance between the two can be moved by the thrust bearing. The surface contact is changed to rolling contact, which effectively reduces the friction between the base turntable 14 and the base 19 ,...

Embodiment 2

[0032] On the basis of Embodiment 1, a number of left limit holes 12 are provided on the support frame 15 near the end of the I-shaped left slide rail 10, and some left limit holes 12 are located on the same side of the I-shaped left slide rail 10. The limiting holes 12 are arranged along the length direction of the I-shaped left slide rail 10 . One end near the right slide rail 11 of the I-type on the bracing frame 15 is provided with some right limit holes 13, and some right limit holes 13 are positioned at the same side of the I-type right slide rail 11, and some right limit holes 13 are along the right side of the I-type. The lengthwise direction of the slide rails 11 is arranged. Left support arm 6 bottom is connected with left screw rod 8, and the outer diameter of left screw rod 8 is compatible with the inner diameter of left limit hole 12, when needing to move left support arm 6, lift left screw rod 8 to make left screw rod 8 stop from the left Break away from the hol...

Embodiment 3

[0035] On the basis of the first or second embodiment, the two sides of the base 19 are also provided with traveling mechanisms. This walking mechanism comprises left lifting roller cover 26, right lifting roller cover 27, left lifting roller 20, right lifting roller 21, handle 18, left lever 16 and right lever 17. The left lifting roller cover 26 is fixedly connected to the left side of the base 19, and the right lifting roller cover 27 is fixedly connected to the right side of the base 19. The central position of left lifting roller cover 26 and right lifting roller cover 27 all offers the rectangular through hole that is used to place lifting roller, makes left lifting roller cover 26 and right lifting roller cover 27 form " back " font structure. The left lifting roller 20 is placed in the rectangular through hole of the left lifting roller cover 26, the left lifting roller 20 can move up and down along the height direction of the left lifting roller cover 26, and the fron...

Abstract

The invention discloses a large-size neodymium glass sheet transmission wavefront error detection fixture, which relates to a clamping device for large-size neodymium glass sheet transmission wavefront error detection in the technical field of special fixtures, and aims to provide a large-size neodymium glass sheet transmission wavefront error detection fixture. The wave surface error detection fixture enables it to simultaneously realize the safe clamping of large-size neodymium glass sheets and the convenient and quick adjustment of the placement angle. Including the base, the two sides of the base are connected with a walking mechanism, the top of the base is connected with a base turntable, and the top of the base turntable is connected with a support frame, and the support frame can rotate around the axis of the base along with the base turntable, and the top surface of the support frame is arranged in sequence from left to right There are I-shaped left slide rails, bottom concave clamps and I-shaped right slide rails. A left support arm that can move along the length direction of the I-shaped left slide rail is arranged on the I-shaped left slide rail. Concave clamping block: the right support arm that can move along the length direction of the right slide rail of the I-type is provided on the right slide rail of the I-shaped, and the right concave clamping block is provided on the right support arm.

Description

technical field [0001] The invention belongs to the technical field of special fixtures, and relates to a clamping device for large-size neodymium glass sheet transmission wave surface error detection, in particular to a device capable of realizing safe clamping, convenient placement angle adjustment and moving transfer of large-size neodymium glass sheets at the same time fixture. Background technique [0002] Large-size neodymium glass is a key component in large-scale high-power solid-state laser devices, and its performance index directly affects the output laser power and beam quality of the entire laser device, and the transmission wavefront error of large-size neodymium glass is the key One of the performance indicators. Large-size neodymium glass sheets need to be placed at specific angles when detecting transmission wavefront errors, so fixtures are required to clamp and fix large-size neodymium glass sheets. [0003] At present, most of the clamping of glass occu...
