Description

Battery lead welding machine

The utility model relates to a battery lead post welding machine, in particular to a storage battery lead post welding machine for welding the lead post and the upper cover of the storage battery in an automatic operation mode.

As shown in Fig. 1 described later, the storage battery 10 (battery) used on general automobiles and locomotives is mainly filled with electrolyte solution in a base 11, so that the electrolyte solution interacts with the zinc plate set in it to achieve electrolysis. For the purpose of discharging, the lead column 13 fixed on the top surface of the upper cover 12 is used as a medium for conducting with the outside world. When the lead post 13 and the upper cover 12 are consolidated, a lead ring 14 must be pre-embedded in the perforation 121 on the top surface of the upper cover 12, and then the lead post 13 is inserted in the lead ring 14, and then the lead post 13 is manually welded. In this way, the lead ring 14 is melted and welded with the lead post 13, so that the lead post 13 and the upper cover 12 are consolidated into one. However, this manual method still has the following disadvantages when it is practical:

One, because the volume of lead ring 14 is not very big, and the operation area during welding is quite small, therefore, this welding work must rely on skilled welder to just be able to finish, thereby often have unqualified product to produce, so finished product quality is unstable.

Two, the output of manual work cannot be improved at all, which not only causes eye or body injury to welders, but also has high cost and low economic benefit.

Therefore, the purpose of the utility model is to provide a battery lead post fusion welding machine which utilizes automatic operation to carry out the fusion welding of the battery upper cover and the lead post.

The battery lead post welding machine according to the utility model includes a conveying platform, a stand, a height adjustment device, an axial adjustment device, a radial adjustment device, two welding torches and a transmission device, and is characterized in that: The conveying platform can transfer the batteries to the processing area in sequence, so that the welding torch and the sliding plate slide up and down between the slideways of the stand with the extension of the cylinder, and are driven by a transmission device to rotate around the lead column, and the upper cover The lead ring melts, so that the lead column and the upper cover are consolidated into one, and the welding torch uses the height adjustment device, the axial adjustment device and the radial adjustment device to adjust the distance, height and front and rear distance, so as to match different sizes of batteries and Positive and negative lead posts with different spacing. The utility model changes the previous manual operation mode and automates the operation, which not only saves manpower and reduces occupational injuries, but also greatly improves productivity and has high economic benefits.
