Locating fixture for cathode plates of ultraviolet photoelectric tube

Abstract

The invention discloses a locating fixture for cathode plates of an ultraviolet photoelectric tube. The locating fixture for the cathode plates of the ultraviolet photoelectric tube comprises a locating sleeve barrel, a locating block, a first slide block, a second slide block, a pull rod and a fixed plate, after the locating block is put in the first slide block and second slide block, one end of a distance piece is inserted in the sleeve barrel body of the locating sleeve barrel and extends towards the outside, the pull rod is inserted in the sleeve barrel body of the locating sleeve barrel through a thread head and is in thread connection with a thread hole of the locating block, and a spring sleeves the outer side of the part of the pull rod inserted in the sleeve barrel body. The locating fixture for the cathode plates of the ultraviolet photoelectric tube is simple in structure, smart in principle and convenient to use and operate; when using, two cathode plates are respectively inserted in the clearance between the distance piece and the first slide block and the clearance between the distance piece and the second slide block, the pull rod pushes the locating block to move towards the outer side by the aid of the spring, the first slide block and second slide block press the distance piece by means of the inclines and sleeve barrel body with taper so that the cathode plates in the clearances are compressed, the cathode plates are located precisely, incapable of sliding and capable of keeping effective clearances, and the produced product is qualified.

Description

technical field [0001] The invention relates to an auxiliary tool for packaging of ultraviolet photoelectric tubes, in particular to a positioning tool for cathode sheets of ultraviolet photoelectric tubes. Background technique [0002] When packaging the ultraviolet photocell, there are high requirements for the position of the cathode sheet, and the current positioning tool is to use the shrapnel to press the cathode sheet for positioning. This shrapnel positioning method can only rely on a lot of The small elastic force presses the parts, and cannot form an effective force to press the parts, so that the parts are easy to fall off and shake, and unqualified products will be produced when the products are packaged after positioning. Contents of the invention [0003] In view of this, the present invention provides a positioning tool for the cathode sheet of an ultraviolet photoelectric cell, which has a good pressing effect on the cathode sheet, accurate positioning, and...
