Abstract
The utility model relates to a rotary grounding device with an adjustable gap and belongs to the field of welding technology in metallurgical industry. A technical scheme is that the rotary grounding device comprises a mandrel (1), a copper sleeve (2), a pressing cover (3), a thrust bearing (4), a butterfly spring (5), and lock nuts (6), that the mandrel is formed by combining two portions with different diameters, that a portion with a large diameter is in a taper shape, that the copper sleeve is disposed on the outer side of the portion with a large diameter, that the pressing cover, the thrust bearing, the butterfly spring, and the lock nuts are disposed on a portion with a small diameter successively, and that the conicity of the pressing cover is matched with that of the mandrel. The copper sleeve is rotated in order to adjust a gap. Then the copper sleeve is guaranteed to be rotated smoothly and the lock nuts are locked thereafter. The rotary grounding device has beneficial effects of preventing a tangle problem of a grounding wire, preventing breakdown of a vertical mill body caused by direct connection between the rotary grounding device and a vertical mill body, guaranteeing an electricity conducting effect, achieving reliable welding and grounding, and achieving convenient assembly and disassembly.
Description
Technical field
The utility model relates to the adjustable rotary earthing device in a kind of gap, belongs to the metallurgy industry welding technology field.
Background technology
At present, in the metallurgy industry welding is produced, all need mill, grinding roller to weld under rotation status in cement vertical mill, the mill of power plant's coal mill, the built-up welding reparation of grinding roller, if use the dead earth clamp, certainly will cause the winding of earth connection, therefore, need be made into the fixed grounding clamp rotary, avoid the winding problem of earth connection.Rotary earthing device structure in the market is: front end is clamp structures, and the rotating part gap is non-adjustable.But the mill grinding roller when wire bonding, can only connect the body of the clamp Vertical Mill of front end, can cause like this Vertical Mill body to puncture.The rotating part gap is non-adjustable, but after using a period of time, the copper sheathing wearing and tearing, gap increases, and conductive effect is poor, causes the built-up welding weak effect.
The utility model content
The utility model purpose is to provide the adjustable rotary earthing device in a kind of gap, regulates with the axle of tapering and the gap of copper sheathing, guarantees conductive effect.Solve the problem that exists in background technology.
The technical solution of the utility model is:
The rotary earthing device that a kind of gap is adjustable, it is characterized in that comprising axle, copper sheathing, gland, thrust bearing, butterfly spring, locknut, described axle is integrally formed by the different two parts of diameter, the part that diameter is large is tapered, the outside is provided with copper sheathing, be provided with successively gland, thrust bearing, butterfly spring and nut on the little part of diameter, gland and axle tapering are complementary.
Described axle tapering face is provided with conductive paste, and locknut is two.
The rotation copper sheathing, adjusting play, guarantee the copper sheathing rotation flexibly, the locking locknut gets final product.After using a period of time, due to the copper sheathing wearing and tearing, gap can increase gradually, will cause poor electric conductivity, at this moment, the outermost end locknut is unclamped, and another locknut is screwed, and after adjusting play is suitable, then the outer end nut-locking is got final product.
The beneficial effects of the utility model are: both avoided the winding problem of earth connection, solved again grounding device and directly be connected on the body of mill, body is breakdown.Guaranteed conductive effect, make welding ground connection more reliable, and dismounting has been very convenient.
Description of drawings
Fig. 1 is the utility model structural representation;
In figure: axle 1, copper sheathing 2, gland 3, thrust bearing 4, butterfly spring 5, locknut 6.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by example.
With reference to accompanying drawing 1, the rotary earthing device that a kind of gap is adjustable, comprise axle 1, copper sheathing 2, gland 3, thrust bearing 4, butterfly spring 5, locknut 6, copper sheathing uses the copper rod that conducts electricity very well to process, axle adopts the 45# steel to process, described axle is integrally formed by the different two parts of diameter, the part that diameter is large is tapered, the tapering face is provided with conductive paste, the outside is provided with copper sheathing, be provided with successively gland, thrust bearing, butterfly spring and nut on the little part of diameter, locknut is two, and gland and axle tapering are complementary.The rotation copper sheathing, adjusting play, approximately 0.2-0.3mm, guarantee the copper sheathing rotation flexibly, the locking locknut gets final product.During use, axle is connected with the drive motors reductor shaft, then the line that will forge iron is fixing gets final product.After using a period of time, due to the copper sheathing wearing and tearing, gap can increase gradually, will cause poor electric conductivity, at this moment, the outermost end locknut is unclamped, and another locknut is screwed, and after adjusting play is suitable, then the outer end nut-locking is got final product.
Claims (2)
1. rotary earthing device that gap is adjustable, it is characterized in that comprising axle (1), copper sheathing (2), gland (3), thrust bearing (4), butterfly spring (5), locknut (6), described axle is integrally formed by the different two parts of diameter, the part that diameter is large is tapered, the outside is provided with copper sheathing, be provided with successively gland, thrust bearing, butterfly spring and nut on the little part of diameter, gland and axle tapering are complementary.
According to claim 1 between the adjustable rotary earthing device of gap, it is characterized in that axle (1) tapering face is provided with conductive paste, locknut is two.
