Abstract
The utility model discloses a protective device for a positioning cylinder of a welding fixture. The protective device comprises a base, a support block is arranged on the base, a positioning cylinder is connected on the support block, a positioning block for installing a workpiece to be welded is fixedly connected on a piston rod of the positioning cylinder, and a lead is fixed on the positioning block and is connected with the base. For the protective device, since the lead is additionally arranged on the positioning block, current generated during welding keeps away from the positioning cylinder, so that internal parts of the positioning cylinder cannot be damaged so as to protect the positioning cylinder, ensure the use safety of the positioning cylinder and prolong the service life of the positioning cylinder.
Description
Technical field
The utility model relates to welding equipment, relates in particular to a kind of protective device that is used for the positioning cylinder of weld jig.
Background technology
Electric welding is a kind ofly to utilize welding rod to pass through high arc temperature to melt a kind of welding operation that realize in place that metal parts need connect.At present, all be provided with the positioning cylinder that is used to move, locate parts to be welded on the general weld jig, still, have electric current directly to pass through during welding, damage the cylinder interior part easily from cylinder block.
The utility model content
In view of the defective that above-mentioned prior art exists, the purpose of the utility model is the protective device that proposes a kind of weld jig positioning cylinder.
The purpose of the utility model will be achieved through following technical scheme:
A kind of protective device of weld jig positioning cylinder; Comprise a base; Said base is provided with a back-up block, is connected with a location cylinder on the said back-up block, and fixed connection one is used to install the locating piece of workpiece to be welded on the piston rod of said positioning cylinder; Be fixed with a lead on the said locating piece, said lead is connected with said base.Welding current is received through lead on the base of weld jig, receives the negative pole of welding machine then through cable, the positive pole of welding gun welder, thus forming welding circuit, positioning cylinder has been walked around with welding current in this loop.
Preferably, the protective device of above-mentioned weld jig positioning cylinder, wherein: said lead is through mechanical fixation, and welding arbitrary mode fixing or that be adhesively fixed is fixed on the said locating piece.
Preferably, the protective device of above-mentioned weld jig positioning cylinder, wherein: the external packets of said lead is wrapped with electrical insulator.
The outstanding effect of the utility model is: the utility model has added lead on locating piece; The electric current that produces during welding has been avoided positioning cylinder, therefore can not damage the inner body of positioning cylinder, the protection positioning cylinder; Guarantee that positioning cylinder is safe in utilization, prolong the positioning cylinder life-span.
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the utility model is done further to detail, so that the utility model technical scheme is easier to understand, grasp.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
The specific embodiment
Embodiment 1:
The protective device of a kind of weld jig positioning cylinder of present embodiment; As shown in Figure 1, comprise base 1, base 1 is provided with back-up block 2; Be connected with positioning cylinder 3 on the back-up block 2; Be fixedly connected the locating piece 4 that is used to install workpiece to be welded on the piston rod 31 of positioning cylinder 3, be fixed with lead 5 on the locating piece 4, lead 5 is connected with base 1.Welding current is received through lead 5 on the base 1 of weld jig, receives the negative pole of welding machine 7 then through cable 6, the positive pole of welding gun 8 welders 7, thus forming welding circuit, positioning cylinder 3 has been walked around with welding current in this loop.Lead 5 is through mechanical fixation, and welding arbitrary mode fixing or that be adhesively fixed is fixed on the locating piece 4.The external packets of lead 5 is wrapped with electrical insulator.
Present embodiment has added lead 5 on locating piece 4, the electric current that produces during welding has been avoided positioning cylinder 3, therefore can not damage the inner body of positioning cylinder 3, and protection positioning cylinder 3 guarantees that positioning cylinder 3 is safe in utilization, prolongs 3 life-spans of positioning cylinder.
The utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within the protection domain of the utility model.
