Description
Technical field
The utility model belongs to the milling tools of electric armour clamp, specifically a kind of wire clamp inwall polishing rod.
Background technology
In electrical construction, on equipment, normal operation has very large impact in the processing of current-carrying part contact-making surface, and the contact resistance that directly affects contact-making surface is processed in the processing of electrical connector, and the size of contact resistance is to affect contact point heating ground key factor.At present, for the processing of the flat contact surface of electric armour clamp, adopt angle grinding machine or flat file very, can be easy to flat contact surface to process the precision of needs, and use the instruments such as round file, sand paper to be also difficult to an oxide layer for contact-making surface in cylinder to process clean for the equipment of the tubulars such as strain clamp and device clamp splicing sleeve, and and dealing with and waste time and energy, the contact resistance of contact-making surface does not reach the precision needing yet, in cylinder, the resistance of contact-making surface is relatively large, leaves hidden danger to the safe operation of electrical network.
Utility model content
Applicant is in electrical equipment construction working for many years, find the problems referred to above, through exploring and research, object is to propose a kind of wire clamp inwall polishing rod, in the time that the equipment for strain clamp and device clamp splicing sleeve etc. with tubular contact-making surface carries out the grinding process of contact-making surface, can be easy to use, save time, ensure that the polishing precision of tubular contact-making surface reaches designing requirement.
Technical solution adopted in the utility model is, a kind of wire clamp inwall polishing rod, its structure comprises: cylindrical hold-down bars and connecting rod, the upper end of described connecting rod and the bottom of cylindrical hold-down bars are connected to a fixed, the axis of connecting rod and cylindrical hold-down bars is on a line, the lower end of described connecting rod is provided with electric drill joint, electric drill joint is connected with described connecting rod, described cylindrical hold-down bars upper, lower two ends are plane, in the upper end of cylindrical hold-down bars, an annular fixed groove is offered respectively in lower end and centre, annular fixed groove arranges with cylindrical hold-down bars is concentric, also on cylindrical hold-down bars, wrap up one deck sand paper, in the outside of sand paper, the position of corresponding circle annular fixed groove arranges bandage, bandage is fixed sand paper.
The beneficial effects of the utility model: when use, after new sand paper is wrapped on cylindrical hold-down bars, by tying up at the bandage at annular fixed groove position, sand paper is fixed, then the electric drill joint of connecting rod lower end is connected with electric drill, the hold-down bars insertion strain clamp and the device clamp splicing sleeve etc. that tie up sand paper are there is to the device interior of tubular contact-making surface, open electric drill, both can polish to tubular contact-making surface, this novel a kind of wire clamp inwall polishing rod, have easy to use, grinding efficiency is high, the effective advantage of polishing, be particularly suitable for applying in power communication industry.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of wire clamp inwall of the utility model polishing rod when sand paper is not installed;
Fig. 2 is the structural representation of a kind of wire clamp inwall of the utility model polishing rod when sand paper is installed.
The specific embodiment
Referring to Fig. 1-2, a kind of wire clamp inwall polishing rod, its structure comprises: cylindrical hold-down bars 1 and connecting rod 2, the bottom of the upper end of described connecting rod 2 and cylindrical hold-down bars 1 is connected to a fixed, the axis of connecting rod 2 and cylindrical hold-down bars 1 is on a line, the lower end of described connecting rod 2 is provided with electric drill joint 3, electric drill joint 3 is connected with described connecting rod 2, described cylindrical hold-down bars 1 upper, lower two ends are plane, in the upper end of cylindrical hold-down bars 1, an annular fixed groove 4 is offered respectively in lower end and centre, annular fixed groove 4 and the concentric setting of cylindrical hold-down bars 1, also on cylindrical hold-down bars 1, wrap up one deck sand paper 5, in the outside of sand paper 5, the position of corresponding circle annular fixed groove 4 arranges bandage 6, bandage 6 is by fixing sand paper 5.
