Description
Technical field
The utility model relates to spot-welding equipment, especially for the equipment of vehicle shock absorber support projection welding, specifically relates to the unsteady frock of a kind of vehicle shock absorber support projection welding.
Background technology
Since the 1950's, the Automobile Manufacture Industry in China solder technology is mainly based on manual welding and electric resistance welding.The resistance welder process has advantages such as production efficiency height, even structure be reliable, therefore makes the field extensive use at auto parts and components.Along with the development of China auto manufacturing, solder technology has obtained great advance, still compares with the auto industry of developed country also to have huge gap.Auto industry is an industry-global business, and abroad, French Renault and Japanese Nissan motor corporation have all adopted the driver's cabin of the full robot line that is welded, and the assembling of driver's cabin, gluing, spot welding are all finished by robot.At home, problem causes the utilization rate of welding robot in the auto parts and components manufacturing low because the developed country that compares of the whole industrial level of automobile industry also has a certain distance, and, technological equipment design level relatively poor such as the repeatable accuracy of part is lower etc.In the face of international competition globalization, the international situation of domestic compentition, for Domestic Automotive Industry can be occupied a tiny space in world's developing of automobile industry, have the raising that relies on the improvement of Manufacturing Technology and the innovation ability that comprise solder technology only, could realize the target of Chinese Automobile Industry ' independent development capability.
Shock absorber is connected between body of a motor car and the vehicle bridge, belongs to the vitals in the automobile suspension system, can increase security, comfortableness to vehicle on the one hand; The vehicle shock absorber support is according to booster actions such as support and rat tail support, QS, oil pipe are arranged on the other hand, its position dimension and form and position tolerance except guaranteeing spare part, also to guarantee the requirement of part welding shearing force equal strength, so the welding of vehicle shock absorber support belongs to the technological difficulties of shock absorber manufacture process.
The projection welding technology is a kind of new solder technology that grows up on the spot welding basis.Be best suited for the welding of mild steel, it is that the profile of utilizing the raised points that processes in advance or part intrinsic, chamfering etc. are the contact-making surface between the part, the electric resistance welding that makes these contact points formation solder joints after collapsing is pressed in upper/lower electrode pressurization and energising heating (function of upper/lower electrode is to transmit pressure-holding workpiece and location-transmission current-the lead part heat of loose weldment and weld zone).Pressure between weldment on the unit are and electric current are shunted lessly, help improving welding quality.The welding deformation that workpiece produces during projection welding is little, and lack (generally between 0.1-2S) weld interval, and often be that a plurality of salient points weld simultaneously, so welding production efficiency height.
According to the characteristics of automobile damper bracket, the projection welding technology has become the process means of main employing.Shown in Figure 16,17, support 801 is welded on the oil tube assembly assembly 802, guarantees 15 ° ± 2 ° of design sizes; 54 ± 0.5; Welding shearing force 9.8KN.Support 801 is that mild steel is stamped to form, and design has two salient points on the part, uses 200 projection welders, utilizes the back welding of self-control frock (referring to Figure 18) location.
Under the demands status of market multi-varieties and small-batch, my company has product kind more than 200 at present, and position and the size of support on oil tube assembly have nothing in common with each other, and contoured cradle has nothing in common with each other, and seems particularly outstanding so make the problem of positioning tool by oneself.By serious analysis and research, come back as follows to the common problem that shows to present technological equipment:
1, mould replacing time is long: owing to support 801, an oil tube assembly assembly 802 are separately fixed at top electrode 1A and bottom electrode 2A, top electrode 1A and bottom electrode 2A do not have the mechanism of aligning, in case the replacing product, the part position size just must be readjusted according to the following steps: range estimation dress mould → little electric current welding → detection size → by the difference in size of adjustment move upper/lower electrode position → little electric current welding → detection size → ... → till size is qualified.This method of adjustment needs 1-2 hour at least to experienced operators, for the new employee, the time that die change needs even nearly 4-6 hour, has a strong impact on manufacturing schedule;
2, quality state instability: positioning accuracy is poor: because welding process is the process of a part energising pressurized, support 801 is positioned at top electrode, and oil tube assembly assembly 802 is positioned at bottom electrode 2A, and it is bigger influenced by human factor; Weld strength instability on the other hand and since part respectively clamping on upper/lower electrode, rigid collision during the welding process contact, the little pressure of salient point contact area is big, precompressed process salient point produces plastic deformation, bump size changes to some extent, the weld strength instability;
3, frock debugging cost height: because the die change process needs little electric current welding back → detection size to readjust the frock position again, the part in the debugging welding process can't carry out secondary welding, scraps totally, has increased production cost of products;
4, frock cost height: because the material of whole frock 90% adopts red copper, the cost of frock is very high.An a kind of support welding of product, the expense of only calculating the frock material reaches 6000～8000 yuan, and there are 200 multiple products in my company at present, two supports of 80% product needed welding is arranged, so the frock expense of product is a no small number.And the red copper material purchases cycle is long, and welding process is subjected to thermal wear very fast, and available part seldom just must monoblock be scrapped after the wearing and tearing on the cube electrode, needs additional frock expense also quite big;
5, the frock safety coefficient is low: support adopts the shell fragment clamping to be positioned at top electrode 1A, and shell fragment is loosening easily, and welding process drops easily under the gravity effect, and because welding process is heated, the life-span of shell fragment is very short.Shell fragment loosening or be subjected to thermal failure for a long time after, the operator is through hand commonly used or change cutter and help part, has very big potential safety hazard;
6, the welding process loss is big: because the part welding process is except that salient point, all the other contact-making surfaces do not have any insulation measures, and shunting is serious, and energising welding process workpiece discharges easily with the frock contact site and wounds, so energy loss is serious, the weldment presentation quality is poor.
