Abstract

The utility model discloses a projection welding machine for stud welding, comprising a welding gun, an upper electrode and a lower electrode. The projection welding machine for stud welding is characterized in that the lower electrode is provided with a downwardly concave placing port in which an insulation sleeve is arranged. The projection welding machine for stud welding is simple in structure, convenient for use, stable and reliable in stud welding quality, low in cost and capable of reducing the production cost.

Description

A kind of projection welder that can be used for carrying out stud welding

Technical field

The utility model relates to welder, particularly a kind of can be widely used at automobile and mechanical industry, the projection welder that can be used for carrying out stud welding.

Background technology

The welding of panel beating parts is common operations in the mechanical industry, particularly auto manufacturing, wherein double-screw bolt is welded very general especially; Yet in the present automobile manufacture industry, in the welding process of plates of automobile parts,, when being welded, adopted double-screw bolt double-screw bolt to plant welder's mode of planting in a large number in order to improve weld strength and stability of the welding quality.But the existing soldering equipment expensive of planting needs tens0000 RMB easily, has increased production cost.Though and use general projection welder welding screw can save cost; But require very high to operation; Especially cross and then be difficult to weld when thin at the corresponding weldering parent sheet metal component material of planting; Operate and careless slightlyly will cause that to plant weldering parent sheet metal component breakdown or come off, cause part function to lose efficacy, produce waste.

Therefore be badly in need of a kind of simple in structurely, easy to use, the steady quality of stud welding is reliable, and cheap, can be used for carrying out the projection welder of stud welding.

The utility model content

The purpose of the utility model provides a kind of simple in structure, easy to use, and the steady quality of stud welding is reliable, and cheap, can be used for carrying out the projection welder of stud welding.

For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:

A kind of projection welder that can be used for carrying out stud welding comprises welding gun, top electrode and bottom electrode, it is characterized in that: described bottom electrode is provided with the recessed mouth of putting into, and the described mouth of putting into is provided with insulation sleeve.

The beneficial effect of the utility model is: because described bottom electrode is provided with the recessed mouth of putting into, the described mouth of putting into is provided with insulation sleeve, just can double-screw bolt be placed on the insulation sleeve of putting into mouth so in use; Regulate the electrode pressure of top electrode and bottom electrode then; Make that double-screw bolt and sheet metal component are under the pressure of top electrode and bottom electrode all the time in process, and then stable operation, can not cause sheet metal component breakdown or come off; Guarantee the quality of production, improved production efficiency; Be provided with insulation sleeve owing to put into mouth in addition, just prevented when operation that like this screw thread silk tooth from being broken by electric current, guaranteed welding quality.The utility model is simple in structure, and is cheap, reduced production cost, practicality very.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model.

Symbol description among the figure:

Welding gun-1, top electrode-2, bottom electrode-3 is put into mouth-4, insulation sleeve-5, sheet metal component-6, double-screw bolt-7

The specific embodiment

Be described further below in conjunction with 1 pair of the utility model of accompanying drawing

The described a kind of projection welder that can be used for carrying out stud welding of the utility model comprises welding gun 1, top electrode 2 and bottom electrode 3, it is characterized in that: described bottom electrode 3 is provided with recessed puts into mouthfuls 4, describedly puts into mouthfuls 4 and is provided with insulation sleeve 5.

Just can double-screw bolt 7 be placed on the insulation sleeve 5 of putting into mouth 4 in use; Regulate the electrode pressure of top electrode 2 and bottom electrode 3 then; Make in process double-screw bolt 7 and sheet metal component 6 be in all the time under the pressure of top electrode 2 and bottom electrode 3, and then stable operation, can not cause sheet metal component 6 breakdown or come off; Guarantee the quality of production, improved production efficiency; Be provided with insulation sleeve 5 owing to put into mouthfuls 4 in addition, just prevented when operation that like this screw thread silk tooth from being broken by electric current, guaranteed welding quality, the utility model is simple in structure, and is cheap, reduced production cost, practicality very.
