Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the schematic diagram that the cutting of the utility model welding gun electrode cap apparatus for shaping does not put in place;
Fig. 2 is the schematic diagram that welding gun electrode cap apparatus for shaping cutting shown in Figure 1 puts in place;
Fig. 3 is that welding gun electrode cap apparatus for shaping shown in Figure 1 cuts the schematic diagram when finishing.
The specific embodiment
See also Fig. 1 to shown in Figure 3, a kind of welding gun electrode cap apparatus for shaping of the present utility model includes cutting cover 3, and is arranged on the dressing stick of cutting cover 3 one ends, and be arranged on the cutting cover 3, with the indicating mechanism that puts in place of dressing stick homonymy, and be arranged on the guiding mechanism of cutting cover 3 other ends; Described guiding mechanism comprises and 3 bearing outsides that link to each other 1 are overlapped in described cutting, and is arranged on the bearing inner sleeve 2 in the bearing outside 1.Wherein, described bearing inner sleeve 2 is used to install and fix electrode cap 10; Described cutting cover 3 is provided with accommodation hole, and described dressing stick is outstanding to be stretched in the accommodation hole, and described bearing inner sleeve matches with described accommodation hole, and described cutting cover also is provided with cutter groove 11; Be provided with elastic component between described bearing inner sleeve and the accommodation hole end face, can make the bearing inner sleeve return freely.In the present embodiment, described dressing stick is an alloy knife 4, and described alloy knife 4 is fixed in the cutter groove 11 of cutting cover, so that electrode cap 10 is cut by jackscrew 5.Described elastic component is a return spring 7, certainly, also can be other existing elastic component, as elastic caoutchouc etc.
The described indicating mechanism that puts in place is included in bit switch 9 and the indicator lamp 6 that electrically connects mutually with location switch 9, and this indicating mechanism that puts in place during rotary cutting, can know that cutting puts in place by being bolted to the end face of cutting cover 3 from indicator lamp; Described bearing outside 1 and bearing inner sleeve 2 be matched in clearance mutually, is provided with ball 8 between described bearing outside 1 and the bearing inner sleeve 2, and described bearing inner sleeve 1 can rotate relative to bearing outside 2; Be provided with groove 14 in the described bearing outside 1, described groove 14 can be accommodated ball 8; Described bearing inner sleeve 2 and described accommodation hole be matched in clearance mutually, described bearing inner sleeve 2 can rotate in accommodation hole and move forward and backward along the axis of accommodation hole by ball 8, described accommodation hole comprises first accommodation hole 12 and second accommodation hole 13 that communicates with first accommodation hole 12, described bearing inner sleeve 2 and return spring 7 are arranged on first accommodation hole 12, described alloy knife 4 outstanding second accommodation holes 13 that stretch into.
During assembling, ball 8 is put into the hole of bearing inner sleeve 2 earlier, on the end face of bearing inner sleeve 2, puts into return spring 7; Again bearing inner sleeve 2 is put into bearing outside 1; Then bearing outside 1 is put into first accommodation hole 12 of cutting cover 3, again with bearing outside 1 and cutting cover 3 welding fabrications; Alloy knife 4 is put into the cutter groove 11 of cutting cover, and adjust cutting angle to suitable position, fixing with jackscrew 5; According to the size of welding gun electrode cap 10 contacts area, adjust the contact point height of location switch 9, promptly finished whole assembling process.
In the operating process, do not need from welding gun dismounting bottom electrode cap 10, as shown in Figure 1, lead by bearing inner sleeve 2, this welding gun electrode cap apparatus for shaping is contained on the electrode cap 10, by two relative balls, 8 clamping keeper electrode caps 10, can guarantee stable being installed on the electrode cap 10 of this welding gun electrode cap apparatus for shaping; As shown in Figure 2, the alloy knife 4 with welding gun electrode cap apparatus for shaping offsets with electrode cap 10 again, so that cut, at this moment, described ball 8 falls into groove 14, has increased the distance of electrode cap 10 with ball 8, can pass through hand-turning like a cork; As shown in Figure 3, by hand-turning, cut, ream electrode cap 10 redundances.Take out this welding gun electrode cap apparatus for shaping, outwell the copper ashes that the inside machines away, repeat above operation, contact with the location switch 9 of the indicating mechanism that puts in place up to electrode cap 10 contact-making surfaces, indicator lamp 6 is promptly glittering, illustrates to cut and finishes.It only needs simple action can finish working angles, and it makes simple, and cost is low, and is easy to operate, the efficient height, and security reliability is good.
