Description

Welding gun

Technical field

The present invention relates to technical field of welding equipment, especially a kind of welding gun for welding.

Background technology

In the maintenance of some industrial goods and electronic product, usually electric iron is used, and existing electric iron includes the sheath be fixedly connected with housing therewith for hand-held housing, outwardly directed heat-generating pipe is provided with in sheath, the termination point casing that heat-generating pipe stretches out is equipped with plumb joint, heater is provided with in heat-generating pipe, the power line of heater connects attaching plug through housing, because this electric iron only has heating function, during welding, workman needs a first hand-held solder, one hand-held electric iron electric iron melts a little solder and is bonded on solder horn, and then put down solder in hand and to take element, element is welded on weldment, in the process, finger will be ironed slightly because of carelessness, and when taking out element from weldment, first solder is scalded molten with electric iron, and then take out element, in the process, solidify because solder also concentrates on cold being easy to of solder chance on weldment, therefore pickup is more difficult, often breaks the loss that pin causes components and parts, and therefore this electric iron also exists inconvenient operation, inefficiency in use and easily makes people come to harm and the problem causing components and parts to lose.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of welding gun automatically entering solder and Absorbable rod excess solder, can solve inconvenient operation, inefficiency and easily make people come to harm and the problem causing components and parts to lose.

In order to solve the problem, the technical solution adopted in the present invention is: this welding gun includes the sheath that is connected with housing and stretches out from sheath and the heat-generating pipe of plumb joint is housed, described housing is provided with charging aperture and hand handle, be provided with the conveying box be arranged on feed pipe and the draw-out device be connected with the piston tail end be arranged in suction tube in described housing, in the cavity that described suction tube surrounds close to the front portion of described plumb joint and the head end of described piston, be provided with spring; Described feed pipe and described suction tube are all identical with described sheath direction, and one end of described feed pipe and described suction tube is all corresponding to described plumb joint, and the other end of described feed pipe connects described charging aperture, and the described suction tube other end connects described housing.

In technique scheme, technical scheme can also be more specifically: in described conveying box, be provided with the driving ratchet be connected with motor, and described driving ratchet place is provided with the first driven ratchet and the second driven ratchet; The gear teeth that described hand engages the tooth above offering the gear installed on the housing with its bearing block, described draw-out device includes the first belt pulley and the second belt pulley that are connected with described piston tail end by belt, and described second belt pulley is sleeved on the central shaft of described gear.

Further: described housing is provided with the switch controlling described heat-generating pipe and described motor, described switch is connected with power electric.

Further: the front end of described housing is provided with the support set installing sheath, feed pipe and suction tube; Described sheath is connected by the first connector with described feed pipe, and described sheath is connected by the second connector with described suction tube.

Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:

1, owing to having offered charging aperture on housing, and in housing, add feed pipe and conveying box, only solder need be sent to from charging aperture during welding, welded header can be delivered to by conveying box, do not need a hand-held solder, a hand-held electric iron, not only avoid and iron finger, and easy to operate, improve operating efficiency.

2, owing to being provided with the driving ratchet be connected with motor in conveying box, described driving ratchet is provided with the first driven ratchet and the second driven ratchet, namely plumb joint place is delivered to by ratchet drive along feed pipe when solder is fed through driving ratchet from charging aperture, feeding is controlled, and due to motor average rate advance make each solder joint well-balanced, improve welding quality.

3, because hand is being above provided with the gear teeth with gears meshing, and gear is connected with piston with belt by belt pulley, when compression hand handle, gear and belt pulley transmit power by belt and drive piston, are pulled out by piston from tail end, producing negative pressure in the cavity that suction tube is surrounded close to the front portion of plumb joint and the head end of piston sucks in this chamber by solder, when unclamp hand time, spring makes piston get back to original position, now the solder solidified can be poured out from suction tube, easy to use, can not components and parts be damaged.

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the invention will be further described:

Welding gun shown in Fig. 1, Fig. 2, Fig. 3, include the sheath 2 be fixedly connected with housing 3 therewith for hand-held housing 3, outwardly directed heat-generating pipe 1 is provided with in sheath 2, the termination point casing that heat-generating pipe 1 stretches out is equipped with plumb joint, heater is provided with in heat-generating pipe 1, housing 3 offers charging aperture and hand 17, be provided with the conveying box 10 be arranged on feed pipe 5 and the draw-out device be connected with piston 122 tail end be arranged in suction tube 12 in housing 3, in the cavity that suction tube 12 surrounds close to the front portion of plumb joint and the head end of piston 122, be provided with spring 121; Feed pipe 5 and suction tube 12 to be all arranged at below sheath 2 and identical with sheath 2 direction, and sheath 2 is connected by connector 8 with feed pipe 5, and sheath 2 is connected by the second connector 18 with suction tube 12; One end of feed pipe 5 and suction tube 12 is all corresponding to plumb joint, and the other end of feed pipe 5 connects charging aperture, and suction tube 12 other end connects housing; The driving ratchet 104 be connected with motor 101 is provided with above in conveying box 10, below corresponding to driving ratchet 104 is provided with the first driven ratchet 102 and the second driven ratchet 103, housing 3 is provided with the switch controlling motor 101 and heat-generating pipe 1, the power line 11 of motor 101 is connected on the button 72 of switch 7, and the button 71 that the power line 9 of heater is connected to switch 7 connects attaching plug through housing; Hand offers the gear teeth on 17, and these gear teeth are meshed with the tooth of gear 16, and housing 3 is provided with bearing block, and the central shaft of gear 16 is installed in this bearing block; Draw-out device include belt 13, one end of belt 13 is connected with piston tail end 122, and the other end of belt 13 furls on the second belt pulley 15 by the first belt pulley 14, and the second belt pulley 15 is sleeved on by its centre bore on the central shaft of gear 16; The front end of housing is provided with the support set 6 installing sheath 2, feed pipe 5 and suction tube 12.
