Description

Thin rectifier tube welding jig

Technical Field

The utility model relates to an electronic components technical field.

Background

The high-power rectifier tube is widely applied to the fields of ships, aviation, national defense, locomotive traction and the like. In some special occasions, the volume and the sealing performance of the rectifier tube are higher. The thin high-power rectifier tube 1, the thin rectifier tube cap 2 and the thin rectifier tube seat 3 are structurally shown in figures 1-3, the thin high-power rectifier tube meets the requirements of the occasions, the thickness of the thin high-power rectifier tube is generally 8-15 mm, most of domestic manufacturers adopt cold pressing sealing at present, and the sealing mode has the advantages of high production efficiency and poor sealing reliability. The other sealing mode is plasma welding sealing, and has the advantages of high sealing reliability, low production efficiency and high process realization difficulty.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned problem that current slim high-power rectifier tube seals the existence, the utility model provides a thin rectifier tube welding jig.

The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: a thin rectifying tube welding fixture comprises a tube cap positioning fixture, a first tube seat positioning fixture and a second tube seat positioning fixture, wherein the first tube seat positioning fixture is located between the tube cap positioning fixture and the second tube seat positioning fixture, the first tube seat positioning fixture is matched with a groove in the upper portion of a thin rectifying tube seat, the front end of the second tube seat positioning fixture is matched with the maximum excircle diameter of the thin rectifying tube seat, and the outer diameter of the first tube seat positioning fixture is matched with the maximum outer diameter of the second tube seat positioning fixture.

And an annular groove is formed in one surface of the pipe cap positioning clamp, which is in contact with the thin rectifying pipe cap.

The outer surface of the first pipe seat positioning clamp is of a conical structure, and the first pipe seat positioning clamp is made of brass.

The utility model discloses a thin rectifier tube welding jig seals technology production efficiency height, the technology with this anchor clamps and realizes that the degree of difficulty is little, and sealing quality is high.

Detailed Description

The utility model discloses an anchor clamps for slim rectifying tube plasma welding are shown in 4-7, by pipe cap positioning fixture 4, first tube seat positioning fixture 5 and second tube seat positioning fixture 6, first tube seat positioning fixture 5 is located between pipe cap positioning fixture 4 and the second tube seat positioning fixture 6, first tube seat positioning fixture 5 and the 3 upper portion recess phase-matchs of slim rectifying tube seat, 6 front ends of second tube seat positioning fixture and the 3 biggest excircle diameter phase-matchs of slim rectifying tube seat, the external diameter of first tube seat positioning fixture 5 matches with the biggest external diameter of second tube seat positioning fixture 6, pipe cap positioning fixture 4 is provided with ring channel 7 with the one side of rectifying tube cap 2 contacts, through the ring channel, reduce the lifting surface area of pipe cap welding anchor ring face, heat conduction space when increasing the welding. First tube socket positioning fixture 5's material is brass, and the surface is the toper, chooses brass for use through the material with first tube socket positioning fixture 5 and the surface sets up to the toper, has guaranteed the good shaping in the narrow and small space of tube socket welding ring face. The outer diameter of the tube seat positioning clamp 1 is matched with the maximum outer diameter of the tube seat positioning clamp 2, so that the thin rectifying tube is uniformly and intensively stressed on a welding ring surface after being arranged in the clamp, and the welding quality is further improved.
