The electrode matrix is a tubular body which is vertically through; the cooling jacket is sleeved on the cavity of the electrode matrix; the gland is in threaded connection with an upper port of the electrode matrix; a center hole of the gland and the cavity of the cooling sleeve form a counter bore; the positioning pin and the spring are arranged in the counter bore; the insulating sleeve is arranged between the positioning pin and the gland; the bottom of the positioning pin is connected with the upper end of the spring; the lower end of the spring is connected with the insulated pad; and a gap is reserved between the outer wall of the cooling sleeve and the inner wall of the electrode matrix. The water jacket of the water jacket type nut welding electrode has novel and reasonable structure, can improve the cooling effect, prolong the service life of the electrode and ensure the welding quality of the nut and the vehicle body.
Description
Technical field
The utility model relates to a kind of resistance welding electrode, especially a kind of nut-welding electrode.
Background technology
Along with China's car output rapidly increases, a large amount of nut welder skills that adopt because on a coachbuilt body 60-100 nut arranged generally, were used for fixing parts such as seat, inside gadget and instrument board, than truck showed increased during vehicle body was made.Electrode is generally used for welded nut and sheet metal, and its inside is provided with sparge pipe and is used for cooling electrode.When top electrode presses down the nut upper surface, under the energising situation, nut and sheet metal are welded together.
The nut-welding electrode of using has a kind of structure as shown in Figure 2 at present.Only comprise bottom electrode among Fig. 2, omitted top electrode simple in structure and that only cooperate bottom electrode to use.Bottom electrode comprises alignment pin 1, gland 2, insulation sleeve 9, spring 3, electrode body 4 and insulating base 5.Electrode body 4 is the tubular body in open-blind hole, upper end, is the gland 2 of through hole in the middle of its upper end is connecting, and gland 2 is connected with electrode body 4 by being threaded.The cell body inner chamber of electrode body 4 is provided with insulating base 5, and insulating base 5 is fixed on the bottom of electrode body 4 cell bodies.Fixedly connected spring 3 lower ends on the insulating base 5, spring 3 upper ends connect and are fixed on the bottom of alignment pin 1.In the hole of alignment pin 1 in the middle of gland 2, and by insulation sleeve 9 maintenance insulation connections.Be provided with cooling water cavity 40 in the electrode body 4, cooling water cavity 40 in electrode body 4, the bottom of insulating base 5, and be communicated with cooling water source.
When traditional electrode welded nut and steel plate, cooling chamber distance electrode surface beeline reaches 40mm as shown in Figure 2, and the cooling chamber volume is 2.3ml only, and cooling effect is poor.Wearing and tearing are easily caused in the temperature higher position of electrode surface like this, and spring temperature height easily causes inefficacy, so service life is low, the nut poor welding quality.These problem has become the principal contradiction of vehicle body nut welding procedure.
Summary of the invention
The utility model provides a kind of water-jacket typ nut-welding electrode, can improve cooling effect, improves electrode life, guarantees the welding quality of nut and vehicle body.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: the water-jacket typ nut-welding electrode, comprise bottom electrode, bottom electrode is by alignment pin, gland, coolant jacket, electrode body, felt pad, spring, insulation sleeve is formed. and described electrode body is the tubular body of up/down perforation, it is characterized in that: coolant jacket is located at the inner chamber of electrode body, gland and electrode body upper port are passed through spiral marking connection, the centre bore of gland and coolant jacket inner chamber constitute counterbore, alignment pin and spring are installed in this counterbore, be provided with insulation sleeve between alignment pin and the gland, the bottom of alignment pin is connected with the upper end of spring, the lower end of spring is connected with felt pad, is provided with the gap between the outer wall of described coolant jacket and the inwall of electrode body.
To improvement of the technical scheme: the bottom of described alignment pin is provided with insulating collar with the position that the upper end of spring is connected.
Beneficial effect:
Use the jacket structure for water novelty of water-jacket typ nut-welding electrode described in the utility model, rationally.Be provided with the gap between the outer wall of coolant jacket and the inwall of electrode body, electrode surface narrows down to 15mm to the cooling chamber beeline like this, the cooling chamber volume is brought up to 8ml, the water-cooled area improves 2.5 times than traditional electrode, recirculated cooling water can be arrived at herein coolant jacket and electrode body are cooled off rapidly, effectively improved cooling effect, can reduce the particularly temperature of working surface and spring of electrode temperature rapidly, therefore can obviously improve electrode life, guarantee nut and automobile body welding quality; The bottom of alignment pin is provided with insulating collar with the position that the upper end of spring is connected, and completely cut off the heat that the location taper pin transmits, and guaranteed that spring works under relatively low temperature; Gland and electrode body upper port are by spiral marking connection, and adopting is threaded makes compact conformation.
