Abstract
The utility model discloses a welder bearing that moves, the outer steel bushing and the interior steel bushing of diameter for 24mm that are 28mm including the diameter, outer steel bushing and interior steel bushing between laid a plurality of bearing, bearing and outer steel bushing and interior steel bushing between be interference fit, the coefficient of friction bigger difficult damage of steel bushing atress simultaneously in the time of can reducing the welder motion, bad bearing influences production line production when avoiding welder to use.
Description
Technical field
This utility model relates to technical field of welding equipment, is specifically related to a kind of welding gun motion bearings for automatic welder(welding machine) dotting equipment.
Background technology
Spot welding belongs to the one of electric resistance welding, it is welded piece to be pressed between two electrodes, and passing to electric current, the resistance utilizing electric current to flow through workpiece contact surface and adjacent domain generation is heated to fusing or mecystasis, is allowed to form a kind of welding method that metal combines.
Traditional motion bearings, is hard friction due to steel bushing and axle when using steel bushing, and coefficient of friction is bigger, does not reaches welding gun design pressure；When using bearing；For rolling friction between bearing and axle, the least welding gun design pressure that can reach of coefficient of friction, but owing to the wall of bearing is relatively thin, cause more greatly bearing damage in welding gun motion middle (center) bearing stress；And field failure is many, maintenance time is longer.
Utility model content
The purpose of this utility model is to provide a kind of welding gun motion bearings, it is possible to reduce the steel bushing stress simultaneously of coefficient of friction during welding gun motion is more very much not easily damaged；When avoiding welding gun to use, bad bearing affects production line production.
This utility model solves its technical problem and be the technical scheme is that a kind of welding gun motion bearings, outer steel sleeve and the interior steel bushing of a diameter of 24mm including a diameter of 28mm, it is laid with some needle bearings between described outer steel sleeve and interior steel bushing, is interference fit between described needle bearing and outer steel sleeve and interior steel bushing.
The beneficial effects of the utility model are: by using special technique to be combined together with steel bushing by bearing, it is possible to reduce the steel bushing stress simultaneously of coefficient of friction during welding gun motion is more very much not easily damaged；When avoiding welding gun to use, bad bearing affects production line production.
Accompanying drawing explanation
Fig. 1 is the structural representation of welding gun motion bearings.
Steel bushing, 3-needle bearing in 1-outer steel sleeve, 2-in figure.
Detailed description of the invention
In order to make this utility model be solved the technical problem that, technical scheme and beneficial effect clearer, below in conjunction with accompanying drawing and embodiment, this utility model is further described.Should be appreciated that embodiment described herein is used only for explaining this utility model, be not used to limit this utility model.
As shown in Figure 1, this utility model one welding gun motion bearings, including outer steel sleeve 1 and the interior steel bushing 2 of a diameter of 24mm of a diameter of 28mm, it is laid with some needle bearings 3 between outer steel sleeve 1 and interior steel bushing 2, is interference fit between needle bearing 3 and outer steel sleeve 1 and interior steel bushing 2.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equal replacement and improvement etc. made within spirit of the present utility model and principle, all should fall within protection domain of the present utility model.
