Description

Tool for right-angle lap joint of busbar

Technical Field

The utility model relates to a female overlap joint instrument field of arranging, more specifically say, relate to a female lapped instrument of arranging right angle.

Background

According to statistics, in the assembly line of the low-voltage switch cabinet unit drawer, the right-angle lapping of the busbar is one of the processes. When the two busbars are fastened in the right-angle lap joint, the fastening piece needs to reach a certain torque after being fastened, and in the fastening process, the busbars are driven to rotate, so that the busbars cannot be in the right-angle lap joint. Because female arranging needs the right angle overlap joint, and the revolving force drives during the fastening, and the manpower can not effectively guarantee female arranging not unmovable, so need reciprocal fastening many times, just can guarantee female arranging right angle fastening overlap joint. The time span for fastening the right-angle lap joint of the two busbars is large, the workload of the process cannot be effectively and accurately calculated, and the whole assembly quantity of the whole assembly line of the drawer of the low-voltage switch equipment unit has certain influence.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome the accurate lower problem of the accurate pair of traditional low-voltage switchgear unit drawer assembly line assembling process that exists among the prior art, provide the female lapped instrument of right angle of arranging that has high assembly precision now.

The utility model discloses a female lapped instrument of arranging right angle, include the plate body as the main part, plate body up end open and to have 2 right angle recesses that are diagonal symmetric distribution, the plate body up end on be equipped with the self-plugging rivet of a plurality of equipartitions, the plate body under the dashpot that opens on the terminal surface has a plurality of equipartitions, the dashpot in be equipped with the buffer device who is used for protecting the plate body.

When the tool is used, according to the principle of a tool limiting method, two busbars are placed in the right-angle groove by utilizing the characteristics of right-angle lap joint, thickness, length, width and fasteners of the busbars, the two busbars are in right-angle lap joint, and the middle joint of the two busbars is fixed by bolts. When manual fastening can be saved, the two busbars are effectively ensured to be in right-angle lap joint, and the fastening time is saved. Be fit for female overlap joint of arranging of circuit breaker in the low-voltage switchgear equipment unit drawer, guarantee right angle fastening overlap joint, avoid not the right angle, need constantly adjust the problem of fastening.

Preferably, the buffer device comprises fixing plates which are respectively arranged on the left side and the right side of the top of the buffer groove, a spring pin is arranged at the lower end of each fixing plate, a buffer plate is arranged at the lower end of each spring pin, a first spring is sleeved on each spring pin, and the upper end and the lower end of each first spring are respectively welded with the lower end of each spring pin and the upper end face of each buffer plate.

Preferably, a long pin rod is arranged between the buffer plate and the fixing plate, limiting blocks are arranged at the left end and the right end of the long pin rod respectively, a pin hole used for installing the long pin rod is formed in the center of each limiting block, the bottom of each limiting block is welded with the upper end face of the buffer plate, a second spring is sleeved on the periphery of the long pin rod, compression rings are welded at the left end and the right end of the second spring respectively, push rods are welded at the side ends of the compression rings, rocker arms are hinged to the other ends of the push rods, the other ends of the rocker arms are hinged to one ends of hinge blocks, and the other ends of the hinge blocks are welded with the sides of the fixing plate.

When placing female arranging, female crowded plate body earlier of arranging, the plate body atress back can produce the holding power with the working face of plate body lower extreme, this holding power can extrude the buffer board, the buffer board be the better rubber slab of elasticity, spring round pin can extrude a spring in extrusion process, can absorb the female pressure of bringing of arranging in a spring deformation in-process, when a spring is compressed, the buffer board can rise slightly, at the in-process rocking arm of rising can drive push rod and clamping ring and go to extrude No. two springs, realize through the deformation of a spring and No. two springs the utility model discloses a multistage buffer function to the protection plate body prolongs the utility model discloses a life.

The utility model discloses following beneficial effect has: simple structure, convenient to use, the assembly precision is high, long service life.
