Description

Plum blossom contact spring assembly fixture

Technical Field

The utility model belongs to the technical field of assembly, and particularly relates to a spring assembly technology.

Background

In a medium voltage switch, a tulip contact is an important component, and 4 springs are arranged in one tulip contact. The existing installation mode needs to manually buckle a spring at the small end of the guide sleeve to form a closed loop, then the closed loop spring is supported by hands, the spring is slightly unfolded along the guide sleeve, and the spring is pressed by hands until the spring is forcibly clamped into a corresponding clamping groove of the copper contact piece. The installation action is repeated for 3 times continuously, and the plum blossom contact can be ensured to be installed completely, so that the manpower is wasted, and the working strength is high. Because the parts are small, and the spring mounting process needs a large force, the difficulty coefficient is large. If exert oneself improperly or the direction of exerting oneself is not right, the unable accurate installation of spring is in the draw-in groove of copper contact, and light then reinstallates, and heavy then the spring bullet flies, has certain potential safety hazard.

SUMMERY OF THE UTILITY MODEL

The utility model provides a plum blossom contact spring assembly tool for solving the problems in the prior art, and adopts the following technical scheme for achieving the purpose.

The frock includes uide bushing, direction curb plate, elastic belt, bolt and clamp plate, and the latch connection clamp plate is passed through to the upper end of direction curb plate, and elastic belt constraint several direction curb plate encloses into the tubbiness, overlaps in the uide bushing upper end, and the uide bushing lower extreme is arranged in to the plum blossom contact, and the uide bushing upper end is arranged in to the spring, and the clamp plate pushes down the direction curb plate, struts elastic belt, moves down along the uide bushing, and the spring is pushed down, entangles the plum blossom contact draw-in groove.

Furthermore, the guide side plate comprises a limiting hole, and the elastic belt penetrates through the limiting hole.

Further, the tool further comprises a positioning column and a base, the positioning column is fixed on the base, the positioning column is sleeved with the plum blossom-shaped contact, and the upper end of the positioning column is arranged in the guide sleeve.

Further, the tool further comprises a support and an air cylinder, the support is mounted on the base, the air cylinder is mounted at the upper end of the support, and the air cylinder extends to press the pressing plate downwards.

Further, base and support include the several pinhole, through different pinhole connection base and support to the height of adjustment frock.

The utility model has the beneficial effects that: the elastic belt binds the plurality of guide side plates to form a barrel shape, and the spring is pressed downwards to be stressed uniformly; the pressure plate presses down the guide side plate to convert point force into surface force; the cylinder replaces manual force, labor intensity is reduced, a plurality of springs can be assembled at one time, stretching is free, and assembly efficiency is improved; the positioning column fixes the plum blossom contact and is accurately assembled; the support and the base are connected through the pin holes, the height of the tool is flexibly adjusted, and the tool corresponds to the plum blossom-shaped contacts of different models.

Reference numerals: the device comprises a support 1, a base 2, an air cylinder 3, a pressure plate 4, a guide side plate 5, a guide sleeve 6, a plum blossom contact 7, a positioning column 8 and a bolt 9.

Detailed Description

The technical scheme of the utility model is specifically explained in the following by combining the attached drawings.

The parts of the tool comprise a support 1, a base 2, a cylinder 3, a pressing plate 4, a guide side plate 5, a guide sleeve 6, a tulip contact 7, a positioning column 8 and a plug pin 9, wherein the four guide side plates 5 are taken as examples, as shown in fig. 1, and are adjusted according to needs in actual use.

The frock structure after the part combination is shown in fig. 2, base 2 and support 1 include the several pinhole, through different pinhole connection base 2 and support 1, with the height of adjustment frock, the location, 8 are fixed in base 2, reference column 8 is entangled to plum blossom contact 7, arrange 6 lower extremes of uide bushing in, 8 upper ends of reference column are arranged in to uide bushing 6, the direction side, the clamp plate 4 is connected through bolt 9 in the upper end of 5, direction curb plate 5 has the spacing hole, elastic belt passes spacing hole, four direction curb plates 5 of constraint, enclose into the tubbiness, the cover is in 6 upper ends of uide bushing, cylinder 3 is installed in support 1 upper end.

The tool is used as shown in figure 3, the spring is arranged at the upper end of the guide sleeve 6, the air cylinder 3 extends, the guide side plate 5 is pressed down through the pressing plate 4 to open the elastic belt, the elastic belt moves down along the guide sleeve 6, and the spring is pressed down to sleeve the plum blossom contact clamping groove.

The cylinder 3 is shortened, the pressure of the pressure plate 4 and the guide side plate 5 is lost, the elastic belt contracts, the guide side plate 5 and the pressure plate 4 move upwards, the guide sleeve 6 is removed, the unassembled tulip contact 7 is replaced, and the spring is continuously installed.
