Description
Technical field
The invention belongs to field of machining, are related to a kind of automatic tensioning mechanism of wire cutting machine.
Background technique
There are many wire cutting machine used by medical rehabilitation market at present, traditional wire cutting machine metal molybdenum filament it is elastic by people
Work is adjusted, and the dynamics of manual adjustment not can guarantee for a long time the service life for unanimously thus influencing molybdenum filament, processing zero
The precision and surface roughness of part, and chip removal is unsmooth, reduces cutting efficiency, fracture of wire situation is easy to appear when serious, in the market
The existing general cost of tensioning mechanism is relatively high, complex process, and stability is not also high.Based on this, applicant is in traditional screwing apparatus
It is optimized on the basis of structure, makes the product.
Summary of the invention
The purpose of the present invention is overcoming defect of the existing technology, a kind of structurally reasonable, operation, the simple side of adjusting are made
Just, the automatic tensioning mechanism of the better wire cutting machine of using effect.
The technical scheme is that a kind of automatic tensioning mechanism of wire cutting machine, including upper support seat, holding screw, on
Directive wheel, litter, upper springs, sliding support, lower directive wheel, connection sheet, lower springs, adjusting nut, the support base
It is connect by screw thread pair with wire cutting body, support base connects litter by screw thread pair, and upper directive wheel is mounted on by bearing block
Above support base, bearing block is held out against by holding screw, and litter lower part is equipped with connection sheet, and the position of connection sheet can pass through adjusting
Nut adjustment, sliding support are slidably matched with litter, and there are upper springs in sliding support upper end, there is lower springs, lower guiding below
Wheel is mounted on above sliding support by bearing block, lower directive wheel and upper directive wheel in the same plane, support base and sliding
Seat is all nylon material.
The purpose of the present invention can be further realized by following scheme: the support base passes through screw thread pair and wire cutting
Body connection, by screw thread pair connection litter, upper directive wheel is mounted on above support base support base by bearing block, bearing block by
Holding screw is held out against.
One embodiment of the present invention is: the litter lower part is equipped with connection sheet, and the position of connection sheet can lead to
Overregulate nut adjustment.
One embodiment of the present invention is: the sliding support is slidably matched with litter, on sliding support upper end has
Portion's spring, there is lower springs below.
One embodiment of the present invention is: the lower directive wheel is mounted on above sliding support by bearing block.
One embodiment of the present invention is: the lower directive wheel and upper directive wheel are in the same plane.
One embodiment of the present invention is: the support base and sliding support is all nylon material.
Beneficial effects of the present invention: the automatic tensioning mechanism of this wire cutting machine, which passes through, increases molybdenum filament cutting line constant tension device,
Make Wire EDM due to molybdenum filament cutting line tension recovery cause roughness of machining surface, cutting efficiency reduce, fracture of wire increase at
This defect occurrence probability further decreases, and the configuration of the present invention is simple is easy to operate, time saving, laborsaving, improves cutting efficiency.
Detailed description of the invention
Fig. 1 is main view of the invention；
Fig. 2 is left view of the invention；
Accompanying drawing number: upper support seat 1, holding screw 2, upper directive wheel 3, litter 4, upper springs 5, sliding support 6, lower directive wheel
