Abstract
The utility model discloses a mechanical pneumatic jacking mechanism for a projection welding machine, which comprises a jacking component, a cylinder and a base; the base is arranged on the working bench of the projection welding machine, the cylinder is arranged on the base, the jacking component is fixedly connected with a piston of the cylinder and comprises a jacking block, the top part of the jacking block is provided with a platform, a through hole for a lower electrode to pass through is arranged on the platform, the cylinder is connected with a travel switch by a pneumatic control mechanism, and the travel switch is connected with an upper electrode. The mechanical pneumatic jacking mechanism utilizes the return action of the upper electrode of the projection welding machine to trigger the travel switch and accordingly separates a part from the lower electrode. Besides, during actual use process, the pneumatic jacking mechanism is adopted for the part projection welding area, small area uniform jacking force is utilized to protect the part molded surface after projection welding against external force, and further avoid unnecessary artificial deformation of parts. The mechanical pneumatic jacking mechanism has simple structure, facilitates dismounting parts for operators and improves the efficiency.
Description
Technical field
The utility model belongs to welding field, relates to a kind of lifting body that is used on the projection welder, the pneumatic lifting body of specifically a kind of mechanical type.
Background technology
Enter the nineties in 20th century, because arc welding process produces a large amount of welding stresses in welding process, generation has a strong impact on to part face of weld quality, make other welding procedures as: spot welding, projection welding etc. more and more is subjected to the favor of auto industry.Wherein projection welding technology is to realize the master that is welded as of nut, screw and sheet material.This type of welding, utilizes transient current that the leg of screw, nut is dissolved, and utilizes welding pressure to make itself and sheet material welding mutually to screw, nut energising by the upper/lower electrode of projection welder, and its characteristics are simple to operate, high efficiency.
During the projection welder welded nut, nut is by the guide-localization of bottom electrode, because the effect of welding heat and welding pressure, nut is squeezed, and the nut internal diameter is dwindled inevitably, when particularly welding the less nut of internal diameter (as M6, M8 etc.), nut is after finishing welding, because internal diameter dwindles, the gap between the guiding of Chang Yin and projection welder bottom electrode is too small, part can't be taken off.
At present, the domestic manual work that generally adopts is finished projection welding, and when running into the problems referred to above, operating personnel often use bigger external force, by force part are taken off from bottom electrode, and part is deformed.And because operating personnel's gesture difference, the deformation that part takes place is irregular often, and this all makes a big impact to the follow-up weld size of part and the debugging of assembly welding clamp.
Therefore, how part is taken off from the projection welder bottom electrode smoothly, do not influence the mechanism of operative employee's speed of welding again, be that those skilled in the art need the technical solution problem always.
The utility model content
The technical problems to be solved in the utility model provide a kind of simple in structure, utilize cylinder backhaul control can be effectively with the lifting body of part jack-up from the bottom electrode, part is broken away from from bottom electrode smoothly.
The utility model is by the following technical solutions:
The pneumatic lifting body of a kind of mechanical type, comprise jacking assembly, cylinder and base, described base is located on the work top of projection welder, cylinder is located on the base, and described jacking assembly is fixedlyed connected with the piston of cylinder, and the jacking assembly comprises jacking block, the top of this jacking block is a platform, be provided with the through hole that bottom electrode passes on platform, described cylinder also is connected with travel switch by pneumatic control mechanism, and described travel switch also is connected with top electrode.
Preferably, described jacking assembly also comprises contiguous block and fixed block, described fixed block fixing with cylinder piston on, described jacking block is connected with fixed block by contiguous block.
Preferably, described pneumatic control mechanism is a pneumatic circuit.
The pneumatic lifting body of the mechanical type that the utility model relates to utilizes the backhaul action of projection welder top electrode, triggers travel switch, thereby part is broken away from from bottom electrode.In addition, in the actual use, can act on part projection welding zone by adopting pneumatic lifting body, utilize the even lifting force of small size, the part profile after the protection projection welding is not subjected to the external force effect, thereby avoids part that unnecessary artificial distortion takes place.The utility model is simple in structure, and has made things convenient for the staff that part is taken off, and efficient is improved.
Description of drawings
The structural representation of the pneumatic lifting body of mechanical type that Fig. 1 relates to for the utility model.
Fig. 2 is the top electrode and the connection diagram that forms switch on the projection welder.
The specific embodiment
Further specify the utility model below in conjunction with the accompanying drawing and the specific embodiment.
As shown in Figure 1, the mechanical type lifting body that the utility model relates to is pneumatic mechanism, comprises fixation kit, Pneumatic assembly, reaches the jacking assembly.Described fixation kit is fixedlyed connected with the work top 7 of projection welder, and described fixation kit is fixedlyed connected with cylinder 6, and described jacking assembly is fixedlyed connected with cylinder piston.
Described jacking assembly comprises jacking block 1, contiguous block 2 and fixed block 3, and jacking block 1 is located on the contiguous block 2, and contiguous block 2 is located on the fixed block 3.Wherein, the top of jacking block 1 is a platform, is provided with a through hole in platform central authorities, and bottom electrode (guiding that comprises bottom electrode) can therefrom pass through.Described fixation kit comprises base 5.Described Pneumatic assembly comprises cylinder 6, and cylinder 6 connects pneumatic circuit, by pneumatic circuit control cylinder 6.Described jacking block 1 is fixedlyed connected by contiguous block 2 with fixed block 3, and described fixed block 3 is connected by bolt 4 with contiguous block 2.Described fixed block 3 is fixedly set on the piston of cylinder 6, and the bottom surface of described cylinder 6 is fixed on the base 5, and described base 5 is fixed on the projection welding work top 7.
The top electrode 9 of projection welder is connecting travel switch 8, and described travel switch 8 connects cylinder 6 by pneumatic circuit, and the variation of travel switch 8 is imported as pneumatic circuit, but control cylinder 6 motions.
As shown in Figure 1 and Figure 2, when projection welder was finished welding, top electrode 9 is return upwards, move upward with driving travel switch 8, by pneumatic circuit, with the piston stroking upward that promotes on the cylinder 6, drive jacking block 1 and produce the even lifting force of small size, make part break away from bottom electrode.Can protect the part profile after the projection welding not to be subjected to the external force effect like this, thereby avoid part that unnecessary artificial distortion takes place.
