Detailed Description
As shown in fig. 1 to 7, the invention provides a channeling-preventing tool for inner and outer plates of an engine cover. In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is described in further detail below.
As shown in fig. 1, the anti-channeling tool for the inner and outer plates of the engine cover is composed of a welding frame 1, 2 outer plate support blocks 2, 8 dummy support blocks 3, 16 clamping units 4, 8 overturning dummy welding mechanisms 5, a negative circuit unit 6, 8 air-cooled cables 7, a welding copper bar 8, a pneumatic button station 9 and an external manual welding tongs 10. Each dummy support block 3 is provided with 1 turnover puppet welding mechanism 5 and 2 clamping units 4 symmetrically arranged on both sides of the turnover puppet welding mechanism 5.
Wherein the outer plate supporting block 2, the profiling supporting block 3, the clamping unit 4, the turnover puppet welding mechanism 5 and the negative electrode circuit unit 6 are connected to the welding frame 1 by bolts, and are provided with insulating gaskets; one end of the positive air-cooled cable 71 is connected to the electrode of the puppet welding cylinder 51 of the overturning puppet welding mechanism 5 by a bolt, and the other end is connected to the positive electrode 81 end of the welding copper bar 8 (the remaining 7 positive air-cooled cables are not shown in the figure); one end of the negative air-cooled cable 72 is connected to the negative electrode circuit unit 6 through a bolt, the other end of the negative air-cooled cable is connected to the negative electrode 82 end of the welding copper bar 8, and an insulating gasket is arranged between the positive electrode 81 and the negative electrode 82 of the welding copper bar 8. The pneumatic button station 9 is connected to the intake and exhaust valves of the clamp cylinder 41, puppet welding cylinder 51, and inversion cylinder 52 via air pipes (not shown). The pneumatic button station 9 controls opening and closing operations of the clamp unit 4, and controls an inverting operation of an inverting cylinder 52 and an extending and contracting operation of an electrode of a puppet welding cylinder 51 in the inverting puppet welding mechanism 5. After welding by using the external manual welding tongs 10, a puppet welding spot is formed.
The welding frame 1 is a square steel pipe.
The working principle and the using process of the invention are as follows:
the puppet welding spot is a spot with connection strength in the traditional sense, and is formed by partially melting the contact part between the edge of the outer plate and the inner plate of the engine cover by using the heat generated by welding with the external manual welding tongs 10. The puppet weld point only needs to satisfy the bonding strength of the inner plate and the outer plate, and does not affect the surface quality of the outer plate of the engine cover. Therefore, the welding current, the welding parameters, the pressure of the welding tongs and other parameters of the external manual welding tongs need to be repeatedly tested and adjusted. And after the welding is finished, taking down the engine cover, and checking whether the puppet welding spots form welding nucleuses and whether the outer plate of the engine cover generates surface defects, thus finishing the anti-channeling working process of the inner plate and the outer plate of the engine cover.
The specific using method comprises the following steps: adjusting the tool to be in an initial open state, placing the engine cover on the tool, pressing the 1 st group of valves of the pneumatic button station, closing the 16 clamping units 4 and the negative circuit unit 6, clamping the clamping units 4 at the edge of the outer plate of the engine cover, and pressing the conductive copper block of the negative circuit unit 6 on the inner plate of the engine cover; pressing the second group of valves 2, overturning 8 overturning puppet welding mechanisms 5 to drive the puppet welding cylinder 51 to swing right above the edge of the engine cover; and pressing the 3 rd group valve to enable the 8 puppet welded cylinder electrodes to extend out and press the electrodes to the edge welding position of the engine cover. An external manual welding tongs 10 is utilized to sequentially weld the welding copper bar 8 for 8 times, and a welding current sequentially passes through the anode welding copper bar 8, the anode air-cooled cable 7, the puppet welding cylinder 51 electrode, the outer engine cover plate, the inner engine cover plate, the cathode circuit unit 6, the cathode air-cooled cable 7 and the cathode welding copper bar 8 to form a loop, so that the welding of the edge of the outer engine cover plate and the inner engine cover plate is completed. After the welding is finished, the 4 th group of valves is pressed, and the electrodes of 8 puppet welding cylinders 51 are retracted; pressing the 5 th group of valves to open the 8 turnover puppet welding mechanisms 5; by pressing the 6 th group of valves, 16 clamp units 4 and the negative circuit unit 6 are opened, and a puppet welding operation on the inner outer plate of the engine cover is completed. After welding by using the external manual welding tongs 10, a puppet welding spot is formed.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
