Description
Technical field
The invention belongs to welding technology field, specifically, particularly a kind of double end separate type resistance spot-welding welding tongs.
Background technology
Under present Trend of Auto Manufacturing Technologies condition, in the manufacturing process of automobile body-in-white, solder technology is absolutely necessary, and wherein ripe spot-welded on technique and superior soldering turret performance play critical effect to the quality of vehicle body.
Spot welding is by electrode pressure welding work pieces to be clipped together, and discharges large electric current so that the contact-making surface of workpiece and electrode melts the formation nugget by the electrode two ends, to reach the welding procedure of welding purpose.Select dissimilar soldering turrets to weld extremely for different welding positions and be necessary, so both improved quality of welding spot, optimized again productive temp.But in the welded body process, all also there is following problem in the welding for being similar to the workpiece such as vehicle body fuel filler cap inner plate structure:
1) the similar workpiece such as filler cap be around sealing, welding gets ready and can only enter from refueling oral pore, soldering turret generally will select the electrode brachium, but refuels the original limited space of oral pore, soldering turret can be interfered with workpiece, thereby affects welding efficiency;
2) oil filler and plate landing limit are few, weld the outside plate of damaging easily when closing rifle;
3) welding of general oil filler is got number ready for 4-6, turns over rifle and get difficulty ready in oil filler, not only inconvenient operation, and inefficiency.
Summary of the invention
It is a kind of easy to operate that technical problem to be solved by this invention is to provide, and can guarantee the double end separate type resistance spot-welding welding tongs of product quality and production efficiency.
Technical scheme of the present invention is as follows: a kind of double end separate type resistance spot-welding welding tongs, two electrode stems that are arranged side by side (1) middle part is hinged, the first horn (2) is installed in the lower end of an electrode stem (1) therein, the second horn (3) is installed in the lower end of another electrode stem (1), inboard in described the first horn (2) lower end is fixedly installed a round end electrode (4), the inboard of the second horn (3) lower end is fixed two cylinder electrodes (5) side by side, described round end electrode (4) and two cylinder electrodes (5) are on sustained height, round end electrode (4) equates with distance between two cylinder electrodes (5), and be provided with copper cushion block (6) between described round end electrode (4) and two cylinder electrode (5).
The present invention combines the advantage of general resistance spot welding tongs and one plane type welding, be fixed on the anchor clamps by the bipolar electrode copper cushion block that soldering turret is separated, and adjust to required weld pads position, the round end electrode of bipolar electrode copper cushion block when soldering turret clamps and on the first horn tightly fitted, guaranteed the stable of welding, also optimized the problem that soldering turret and workpiece are interfered, not only easy to operate, and can guarantee product quality.In addition, the bipolar electrode copper cushion block is easy for installation, and it is little to take up room, and exempts from dismounting, can install in the weld pads many places.Two cylinder electrodes can weld 2 points simultaneously, have also reduced the time that soldering turret turns over rifle, have improved welding efficiency.
An end face at described copper cushion block (6) is provided with circular groove, and copper cushion block (6) matches with round end electrode (4) by this circular groove, in conjunction with closely, can further guarantee the stability of welding between the two; Another end face at copper cushion block (6) is formed with two boss (6a), these two boss (6a) are corresponding one by one with two cylinder electrodes (5), two boss and two cylinder electrodes are clamped in respectively the both sides of welding position, the location is reliable, can further improve welding quality.
Described copper cushion block (6) is made by chromium pick copper product.Chromium pick copper has good electric conductivity, thermal conductivity, and hardness is high, wear-resisting antiknock, crack resistance and softening temperature are high, and export license is few when welding like this, and speed of welding is fast, and the welding totle drilling cost is low.
Be provided with the first locating piece (7) on the next door of described boss (6a), the below of the first locating piece (7) is provided with the second locating piece (8), described the first locating piece (7) and the second locating piece (8) are rectangular structure, the first locating piece (7) fixes by upper end and the copper cushion block (6) of bolt and spring leaf (9), and the lower end of spring leaf (9) fixes by bolt and the second locating piece (8).The second locating piece is used for jockey, between anchor clamps and the copper cushion block spring leaf is set, and utilizes spring leaf to have the characteristic of strain, and copper cushion block and workpiece are fitted closely, is conducive to improve welding quality.
Beneficial effect: the present invention can be used in the welding of the similar workpiece such as filler cap, soldering turret can not interfered with workpiece, can effectively prevent the welding workpiece of damaging when closing rifle, not only simple to operate, welding quality is secure, and once can weld simultaneously 2 points, and reduced the time that soldering turret turns over rifle, greatly improved welding efficiency.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic diagram that the present invention takes off copper cushion block.
Fig. 3 is use state diagram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, the present invention is comprised of members such as electrode stem 1, the first horn 2, the second horn 3, round end electrode 4, cylinder electrode 5, copper cushion block 6, the first locating piece 7, the second locating piece 8 and spring leafs 9.Wherein, two electrode stem that is arranged side by side 1 middle parts are hinged, and the set-up mode of electrode stem 1 is same as the prior art, and therefore not to repeat here.The first horn 2 is installed in the lower end of an electrode stem 1 therein, round end electrode 4 of inboard fixed installation of these the first horn 2 lower ends; The second horn 3 is installed in the lower end of another electrode stem 1, the inboard of the second horn 3 lower ends is installed two cylinder electrodes 5 side by side, described round end electrode 4 and two cylinder electrodes 5 are on sustained height, and round end electrode 4 equates with distance between two cylinder electrodes 5.
