Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of Split type electric cartridge welding vacuum tube boss lower clamp.
Background technology
When carrying out vacuum tube butt-joint, producing through multiple welding, there are wearing and tearing unavoidably in the bottom electrode of boss lower clamp.When wearing and tearing occur the bottom electrode of boss lower clamp, must carry out safeguarding and even change.But due in existing boss lower clamp, lower electrode tip is integral type, if will change, just must change whole lower electrode tip, cost is higher, changes loaded down with trivial details.
Therefore, need to design a kind of Split type electric cartridge being convenient to the welding vacuum tube boss lower clamp changed.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of Split type electric cartridge being convenient to the welding vacuum tube boss lower clamp changed.
In order to achieve the above object, the utility model devises a kind of Split type electric cartridge welding vacuum tube boss lower clamp, comprise bottom electrode, it is characterized in that: the top of electrode tip holder is provided with blind hole, the upper end of blind hole is embedded with bottom electrode, the bottom of blind hole and the end thereof contacts of spring, the other end of spring is set in the bottom of alignment pin, and the top of alignment pin is passed bottom electrode and protrudes.
The middle part of described bottom electrode is provided with boss, and the two sides, front and back of boss are globoidal structure, and the left and right sides of boss are planar structure.
The lower end of described alignment pin is provided with the frustum of a cone.
The lower end of described electrode tip holder is provided with connecting plate, and connecting plate is provided with four shoulder holes, adopts connecting plate to fix between electrode tip holder and boss lower clamp.
The utility model compared with the existing technology, devise the electrode tip assembly structure of electrode tip holder, bottom electrode and alignment pin split, bottom electrode changes insulation high-abrasive material into, after bottom electrode weares and teares, the assembling of whole electrode tip need not be changed, only need pull down bottom electrode to change, make replacing more convenient, also reduce maintenance cost.

See Fig. 1 and Fig. 2,1 is electrode tip holder; 2 is spring; 3 is bottom electrode; 4 is alignment pin.
Detailed description of the invention
Now by reference to the accompanying drawings the utility model is described further.
See Fig. 1-Fig. 5, the utility model devises a kind of Split type electric cartridge welding vacuum tube boss lower clamp, comprises bottom electrode.The top of electrode tip holder 1 is provided with blind hole, and the upper end of blind hole is embedded with bottom electrode 3, the bottom of blind hole and the end thereof contacts of spring 2, and the other end of spring 2 is set in the bottom of alignment pin 4, and the top of alignment pin 4 is passed bottom electrode 3 and protrudes.
In the utility model, the middle part of bottom electrode 3 is provided with boss, and the two sides, front and back of boss are globoidal structure, and the left and right sides of boss are planar structure, and the design of boss is the handling for the ease of bottom electrode 3.
In addition, bottom electrode 3 adopts insulation high-abrasive material to make, and improves the wearability of bottom electrode 3, thus extends the service life of bottom electrode 3.
The lower end of alignment pin 4 is provided with the frustum of a cone, and the interior bone respective outer side edges of the frustum of a cone and bottom electrode 3, plays spacing effect.
The lower end of electrode tip holder 1 is provided with connecting plate, and connecting plate is provided with four shoulder holes, adopts connecting plate to fix between electrode tip holder 1 and boss lower clamp.
The utility model, after bottom electrode 3 weares and teares, clamps boss by fixture, is taken off by bottom electrode 3 and the bottom electrode 3 more renewed, and is enclosed within by new bottom electrode 3 in the outer also intercalation electrode seat 1 of alignment pin 4, so far, completes the replacing of bottom electrode 3.
The utility model, after bottom electrode 3 weares and teares, need not be changed the assembling of whole electrode tip, only need pull down bottom electrode 3 and change, make replacing more convenient, also reduce maintenance cost.
