Description

A device for removing end plug electrodes of a pressure resistance welding machine

technical field

The utility model belongs to the manufacturing technology of a pressurized water reactor nuclear power fuel assembly, in particular to a device for removing an end plug electrode of a pressure resistance welding machine.

Background technique

The establishment of the pressurized water reactor nuclear fuel element manufacturing production line can meet the needs of my country's nuclear power development. In the manufacturing process of the pressurized water reactor nuclear power fuel assembly, according to the equipment requirements of the fuel rod pressure resistance welding machine, it is necessary to support the fuel rod pressure resistance welding machine End plug electrodes for installation and removal.

In the prior art, a torque wrench is used to remove the end plug electrode, but due to the limited working space of the operator, it is very difficult to disassemble and install, and the labor intensity increases. At the same time, improper removal of the end plug electrode will cause the consumption of welding machine spare parts.

Contents of the invention

The purpose of the utility model is to provide a device for removing the electrode of the end plug of a pressure resistance welding machine, which is easy to operate,

The technical scheme of the utility model is as follows:

A terminal plug electrode removal device for a pressure resistance welding machine, which includes a disassembly body, the disassembly body includes an adapter and a square body fixedly connected with the adapter, the outer end surface of the square body is processed with a card slot, The end plug electrode for disassembly is placed in the groove, and there is a gap between the slot and the end plug electrode.

In the above-mentioned device for removing the end plug electrode of the pressure resistance welding machine: it also includes a sleeve arranged outside the adapter.

In the above-mentioned terminal plug electrode removal device of a pressure resistance welding machine: a wrench is fixed on the sleeve.

In the above-mentioned device for removing the end plug electrode of a piezoresistance welding machine: the clamping groove is an octagonal clamping groove.

In the above-mentioned device for removing the end plug electrode of a pressure resistance welding machine: the adapter is a cylinder with a hexagonal cross-section.

The beneficial effects of the utility model are: the wrench is installed on the disassembly body through the sleeve, and the torque is transmitted to the adapter by using the wrench to realize the disassembly of the end plug electrode, which solves the problem of limited working space and reliably clamps the end plug electrode , while avoiding damage to the electrode by the wrench. At the same time, the labor intensity of operators and the consumption of welding machine spare parts are reduced.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in FIG. 1 , the end plug electrode removal device of the pressure resistance welding machine includes a dismounting body 6 , a sleeve 3 arranged outside the dismounting body 6 , and a wrench 5 is fixedly installed on the sleeve 3 .

As shown in Figure 2a and Figure 2b, the disassembly body 6 includes two parts of a square body and a cylinder with a hexagonal cross-section. The octagonal draw-in groove 1 is a sinking groove, and a cylinder with a hexagonal cross section is used as an adapter 2. A sleeve 3 is installed outside the adapter 2. The inner wall section of the sleeve 3 is processed into a hexahedron, and the outside of the sleeve 3 is Fix the installation wrench 5.

The end plug electrode 4 is placed in the octagonal slot 1, and there is an installation gap between the octagonal slot 1 and the end plug electrode 4, which is convenient for installation and disassembly of the device.

The adapter 2 is connected to the sleeve 3, and the adapter 2 is rotated by a wrench to separate the disassembly body 6 from the end plug electrode 4 .

Adopt the above-mentioned dismounting body 6 of stainless steel support, increase its structural strength.
