Abstract

The utility model provides a parallel double torsional spring winder, comprising a base, a winding supporting frame which is fixed on the base, a driven gear which is fixed at one end of the winding supporting frame, a driving gear which is engaged with the driven gear and fixed on the winding supporting frame, a handle which is connected with the driving gear and drives the driving gear to rotate, a core axle which is fixed at the other end of the winding supporting frame and a snap ring stop which is fixed at the middle part of the core axle. The parallel double torsional spring winder is characterized in that the parallel double torsional spring winder also comprises a steel wire holding frame which is fixed in the long type hole of the base and is parallel with the core axle. The pressure plate on the steel wire holding frame is fixed through a pressure spring and the screw bolt of a pressure plate, and the spring steel wire enters the snap ring stop through the space between the steel wire holding frame and the pressure plate to wind. The parallel double torsional spring winder can improve the universal performance, reducing the manufacturing cost of tooling, improving the work efficiency, and being suitable for the mass production. The quality of the torsional spring which is winded is more stable, and the qualification rate is higher.

Description

Block form torsion spring coiling device

Technical field: the utility model relates to a kind of block form torsion spring coiling device.

Background technology: in the prior art, the coiling of block form torsion spring adopts manual winding instrument to come coiling usually, the block form torsion spring of every kind of specification will use a kind of frock, and need the operator to use handle to twine on the other hand, the hand-held steel wire to be wound of another or on iron plate boring steel wire to be wound is inserted clamped wire in the iron plate hole, so have that versatility is relatively poor, the frock manufacturing expense is higher, work efficiency is lower, a defective such as inapplicable production in enormous quantities and the torsion spring quality instability, the qualification rate that wind up are lower.For overcoming these defectives, block form torsion spring coiling device is developed.

Summary of the invention: technical problem to be solved in the utility model is that a kind of block form torsion spring coiling device will be provided, and it can improve universal performance, reduction frock manufacturing expense, the work efficiency that improves effectively, the suitable torsion spring quality of producing in enormous quantities and winding up is stable, qualification rate is higher.

The technical scheme that its technical problem that solves the utility model adopts is:

It comprises base, be fixed in the winding support on the base, be fixed in the driven gear that twines support one end, the driving gear that twines on the frame that is fixed in the driven gear engagement, the rocking handle that is connected and drives the driving gear rotation with driving gear, be fixed in the mandrel that twines on the support other end, be fixed in the clasp block at mandrel middle part, be fixed in steel wire holding frame parallel in the base long shape hole with mandrel, by the fixing pressing plate on the steel wire holding frame of compression spring, follower bolt, spring steel wire enters between steel wire holding frame and pressing plate and carries out coiling in the clasp block.

Described mandrel is to be fixed in by the mandrel screw to twine the body seat other end.

The beneficial effect that the utility model is produced against existing technologies:

1, the spring steel wire clamp structure that has adopted pressing plate, follower bolt, compression spring to constitute owing to the utility model, spring steel wire enters in the clasp block between steel wire holding frame and pressing plate; To the torsion spring arranged side by side of different size, only need commutation to answer the mandrel and the just energy coiling of clasp block of specification; So it can improve universal performance effectively, reduces the frock manufacturing expense, improves work efficiency, be suitable for and produce in enormous quantities.

2, because the utility model can be regulated the pressure size that follower bolt compresses steel wire by compression spring, and then the tensile force of adjusting coiling torsion spring arranged side by side, make the pressure unanimity of two strands of steel wires, the torsion spring angle unanimity, the quality that wind up are stable, qualification rate is higher so can make.
