Abstract
The invention discloses a ring-shaped part multiple-spot welding process method. The ring-shaped part multiple-spot welding process method comprises the steps of firstly measuring a circular-ring inner diameter of an annular part, adjusting the horizontal diameter of a positioning pin, enabling the horizontal diameter of the positioning pin to be smaller than the circular-ring inner diameter of the annular part, supporting the annular part, fixing the positioning pin on a connecting rod through a locking bolt, enabling the annular part to sleeve the positioning pin, adjusting horizontal positions of the positioning pin and a welding machine electrode, enabling the position required to be welded of the annular part to be perpendicular to the welding machine electrode, and performing readjustment to enable contact faces of the positioning pin and the annular part to be located on the same plane with a lower electrode of a welding machine. The ring-shaped part multiple-spot welding process method can achieve quick multiple-spot welding based on a common seat spot welding machine, an operator can simply and conveniently repair the electrode, conveniently and quickly replace other products during welding and perform operation by himself/herself.
Description
Technical field
The present invention relates to a kind of spot-welding technology method, particularly a kind of ring-shaped work pieces multiple spot welding process.
Background technology
At present, known multiple spot is welded with two kinds of methods, the first adopts common welding machine and multipoint electrode in conjunction with welding, to switch on by three electrodes of a transformer control simultaneously, shortcoming is to ensure that the electric current, the pressure that between each upper/lower electrode, pass through are consistent, thereby cannot ensure the quality of three solder joints; It two is to adopt special multiple-spot welding machine to weld, and this kind of multiple-spot welding machine is expensive, puts that more multivalence lattice are more expensive, and is usually used as special plane, and utilization rate of equipment and installations is not high, cannot use it to produce other products or be difficult to use it to produce other products.
Summary of the invention
The object of the invention is to adopt common welding machine and multipoint electrode in conjunction with ensureing the quality of solder joint or adopt the special low problem of multiple-spot welding machine utilization rate of equipment and installations in order to solve existing multiple spot welding, and a kind of ring-shaped work pieces multiple spot welding process is provided.
General principle of the present invention is to utilize the horizontal relative position of alignment pin restriction ring-shaped work pieces and electrode welder, and ensures the vertical range between ring-shaped work pieces and electrode welder, welds ring-shaped work pieces solder joint around by rotary annular part.
Specific works method of the present invention: the internal radius of first measuring ring-shaped work pieces, adjust the horizontal diameter of alignment pin, make the horizontal diameter of alignment pin be greater than the internal radius of ring-shaped work pieces, ring-shaped work pieces is held up, by clamping screw, alignment pin is fixed on connecting rod, ring-shaped work pieces is enclosed within on alignment pin, adjust alignment pin and the top electrode of welding machine and the horizontal level of bottom electrode, the position that ring-shaped work pieces need to be welded is vertical with bottom electrode with the top electrode of welding machine, then adjusts the contact-making surface of alignment pin and ring-shaped work pieces and the bottom electrode of welding machine at grade.
Described alignment pin is fixed on electric welding machine by connecting rod, between alignment pin and connecting rod, be provided with felt pad, alignment pin is hollow structure, and the centre of alignment pin is provided with insulation sleeve, and clamping screw is fixed on alignment pin on connecting rod through insulation sleeve and felt pad.
If this welding machine will change other productions, only need unload clamping screw, take away alignment pin.
For preventing shunting between the top electrode of alignment pin and welding machine welding machine and bottom electrode, around clamping screw, be provided with insulation sleeve, be provided with felt pad in the bottom of alignment pin.
Position and connected mode need to be determined according to actual conditions and part shape in the position of connecting rod, are not here described.
Beneficial effect of the present invention: the present invention can realize quick multi-point welding on the basis of common seat mash welder, operator repaiies that to frustrate electrode simple and convenient, and convenient and swift while changing other products welding, operator self just can solve.

Detailed description of the invention
Refer to shown in Fig. 1 and Fig. 2, for embodiments of the invention, first measure the internal radius a of ring-shaped work pieces, adjust the horizontal diameter b of alignment pin 1, make the horizontal diameter b of alignment pin 1 be greater than the internal radius a of ring-shaped work pieces, ring-shaped work pieces is held up, by clamping screw 2, alignment pin 1 is fixed on connecting rod 5, ring-shaped work pieces is enclosed within on alignment pin 1, adjust alignment pin 1 and the top electrode 8 of welding machine C and the horizontal level of bottom electrode 7, the position that ring-shaped work pieces need to be welded is vertical with bottom electrode 7 with the top electrode 8 of welding machine C, adjust again the contact-making surface 6 of alignment pin 1 and ring-shaped work pieces and the bottom electrode 7 of welding machine at grade.
Described alignment pin 1 is fixed on electric welding machine C by connecting rod 5, between alignment pin 1 and connecting rod 5, be provided with felt pad 4, alignment pin 1 is hollow structure, and the centre of alignment pin 1 is provided with insulation sleeve 3, and clamping screw 2 is fixed on alignment pin 1 on connecting rod 5 through insulation sleeve 3 and felt pad 4.
If this welding machine C will change other productions, only need unload clamping screw 2, take away alignment pin 1.
For preventing shunting between the top electrode 8 of alignment pin and welding machine C and bottom electrode 7, around clamping screw 2, be provided with insulation sleeve 3, be provided with felt pad 4 in the bottom of alignment pin 1.
Position and connected mode need to be determined according to actual conditions and part shape in the position of connecting rod 5, are not here described.
