Embodiment Construction
[0017] The present invention will be further described below with reference to the accompanying drawings and in conjunction with the embodiments.
[0018] The invention is a clamp used when the anode assembly of the rectifier tube is sealed with the glass tube shell, and plays the role of fixing and positioning the two parts.
[0019] refer to figure 1 , The sealing fixture of the present invention is mainly composed of a base 1 , a fixing ring 2 , a positioning shrapnel 3 , a positioning chuck 4 and a clamping rod 5 . The above-mentioned positioning elastic piece 3 is generally processed by elastic alloy material. The clamping rod 5 is mainly used for clamping the whole fixture on the sealing equipment to realize clamping.
[0020] Such as figure 2 As shown, the base is a T-shaped structure, including a cylindrical head and a stem. The clamping rod 5 is installed at the center of the head of the base 1 through threaded connection, and the positioning chuck 4 is installed...

The invention discloses a sealing clamp for a rectifier tube anode assembly. The sealing clamp comprises a base, fixing rings, positioning elastic pieces, a positioning chuck and a clamping rod. The base is of a T-shaped structure. The clamping rod is installed in the center of the head of the base in a threaded connection manner. The positioning chuck is installed in the center of the tail end of a rod part of the base in a threaded connection manner. The positioning chuck is internally provided with a positioning hole used for clamping an anode. The fixing rings are arranged on the periphery of the rod part of the base in a sleeving manner through clearance fit. Open holes are formed in the fixing rings. The positioning elastic pieces are of piece-shaped structures with bent middles. One ends of the positioning elastic pieces are clamped between the rod part of the base and the fixing rings, and the other ends of the positioning elastic pieces stretch out from the open holes. According to the sealing clamp for the rectifier tube anode assembly, precision and consistency in sealing can be well ensured, and meanwhile breaking of a glass pipe shell due to excessive clamping force cannot happen; and in addition, the clamp is simple in structure, low in technology achieving difficulty coefficient and convenient to use and operate.
Description
technical field [0001] The invention relates to a processing device for a glass stripe screen, which belongs to the field of mechanical design. Background technique [0002] In the manufacture and production of cold cathode rectifier tubes, the sealing link of the anode assembly is very important, and the accuracy of the sealing of the anode assembly directly determines whether the technical indicators of the product can meet the requirements. At present, the sealing of the anode assembly mainly adopts spring collet clamping. The clamping of the spring collet can not guarantee the sealing accuracy very well and it is not easy to grasp the clamping force, which often leads to the breakage of the glass tube shell, the product is scrapped, and its production efficiency is extremely low. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a sealing fixture for the sealing of the anode assembly, which aims to improv...
