Abstract
The utility model relates to a welding apparatus and especially relates to a positioning earthing device for rotation welding. The purpose of the utility model is providing the positioning earthing device for rotation welding and the positioning earthing device can avoid phenomenon of cable distortion winding and sparking of a cylinder outer wall. The technology scheme of the utility model is that the positioning earthing device for rotation welding comprises a roller base, two rollers, two mandrels, a counterweight, a hammer shaft and a hanging plate. One end of the hanging plate is fixed on one end of the roller base, and the hammer shaft is fixed on the other end of the hanging plate near an edge and is provided with the counterweight. The two mandrels are fixed on the roller base. The two rollers are sleeved on the mandrels. The beneficial effects of the scheme are that the positioning earthing device can keep a cylinder to rotate and the device don't rotate with the cylinder, thereby avoiding cable distortion winding, reducing cable damage, increasing service life of the cable, reducing welding labor intensity and raising work efficiency; and the device and a cylinder inner wall are tightly contacted, so that quality of a cylinder outer surface can't be harmed if an earthing sparking phenomenon appears.
Description
Technical field
The utility model relates to a kind of welding equipment, relates in particular to a kind of rotation welding location earthing device.
Background technology
At present, to the electric welding of welding work pieces of rotation, normally adopt ground wire is fixed on the workpiece and weld.This mode is when welding current is large, and owing to the cable as ground wire is not only thick but also heavy, fixing and dismounting is all required great effort very much at every turn.And owing to being that the workpiece that rotates is welded, along with the rotation of workpiece, cable also can twine, and this winding is distorted cable, after cable is twisted is shortened useful life.Therefore, the method labour intensity that ground wire is fixed on weld on the workpiece is large, inefficiency, and the useful life of cable is short.
The utility model content
The purpose of this utility model provides a kind of rotation welding location earthing device, and it can avoid the distortion of cable to twine in the process of welding, reduces the infringement to cable, increases the useful life of cable, reduces the labour intensity in the welding process, increases work efficiency.
In order to solve described technical problem, the technical solution of the utility model is: a kind of rotation welding location earthing device, comprise roller bearing pedestal, roller bearing, mandrel, counter weight, hammer axle and link plate, one end of described link plate is fixed on roller bearing pedestal one end, the submarginal place of the other end of link plate is fixed with the hammer axle, on the described hammer axle counter weight is arranged, be fixed with mandrel on the described roller bearing pedestal, cover has roller bearing on the described mandrel.
The beneficial effect of this programme is: this positioner can keep barrel body rotation and ground connection is located not transfer, can avoid the distortion of cable to twine, and reduces the infringement to cable, increases the useful life of cable, reduces the labour intensity in the welding process, and operating efficiency is provided; This device inwall closing contact does not injure the container outer surface quality if any the ground connection spark phenomenon yet.
Further, described mandrel is two.
The beneficial effect of above-mentioned further improvement project is: adopt two roller bearings to take turns the rolling earthing method more, device is rolled at cylinder inboard wall better.
Further, described counter weight on the hammer axle away from an end of link plate.
The beneficial effect of above-mentioned further improvement project is: counter weight can be avoided device because deadweight is dropped from welding large-diameter cylinder body workpiece at that end away from link plate.
Further, the material of described welding ground connection positioner is steel.
The beneficial effect of above-mentioned further improvement project is: device has corresponding deadweight, so ground connection is functional.
Description of drawings
Fig. 1 is structural front view of the present utility model;
Fig. 2 is structure left view of the present utility model;
Schematic diagram when Fig. 3 is the utility model use.
In the accompanying drawing, the list of parts of each label representative is as follows:
1, roller bearing pedestal, 2, roller bearing, 3, mandrel, 4, counter weight, 5, the hammer axle, 6, link plate, 7, circular cylinder body.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
Such as Fig. 1, shown in Figure 2, the present embodiment is by roller bearing pedestal (1), roller bearing (2), mandrel (3), counter weight (4), hammer axle (5), link plate (6) forms, one end of link plate (6) is fixed on roller bearing pedestal (1) one end, the submarginal place of the other end of link plate (6) is fixed with hammer axle (5), on the hammer axle (5) counter weight (4) is arranged, the two ends of roller bearing pedestal (1) are fixed with two mandrels (3), the position of two mandrels (3) on roller bearing pedestal (1) is about link plate (6) symmetry, and the upper cover of each mandrel (3) has roller bearing (2), and roller bearing (2) can rotate around mandrel (3).In the present embodiment, the material of roller bearing (2), mandrel (3), counter weight (4) 4, hammer axle (5) is the 45#(45 steel), the material of link plate (6) is the trade mark of Q235(structural carbon steel, the yield strength that represents this steel is 235MPa), the material of roller bearing pedestal (1) is 250 channel-section steels (represent the waist height and be the channel-section steel of 250mm).
Schematic diagram when the utility model as shown in Figure 3 uses, during welding, circular cylinder body (7) is positioned on the welding bench, the roller bearing of the utility model embodiment device (2) places on the inwall of circular cylinder body (7), in welding process, because the needs of welding, need to rotate circular cylinder body (7), because this positioner has corresponding deadweight, and roller bearing (2) can rotate around mandrel (3), ground connection is located not transfer so this positioner can keep barrel body rotation, thereby avoided the puzzlement of earth connection transfer, also avoided winding and the distortion of cable, avoided the work of cleaning cable in welding process, reduce the amount of labour of welding, improved operating efficiency.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
