Abstract
The utility model discloses a spring machine diameter changing mechanism. The spring machine diameter changing mechanism comprises a ball screw and a diameter changing sliding block, wherein the ball screw penetrates through the diameter changing sliding block and is connected with the diameter changing sliding block in a threaded manner; the diameter changing mechanism is internally provided with a motor gear and a reduction gear which are meshed with each other; the screw is driven through the motor gear, so that a torque transmitted by a motor and an abutting and pushing force of the screw are increased; moreover, a servo motor is designed at the upper end of gearbox, so that the diameter changing mechanism is convenient to install, the problem that a wrench is inconvenient to operate because of the influence of the position of the servo motor during installation is prevented; the side of the diameter changing sliding block is provided with a limiting baffle plate parallel to the ball screw, and the sliding block is provided with a sensing block capable of sensing with an inductance type proximity switch; when the sensing block reaches to upper and lower limit points, the diameter changing sliding block automatically stops, and the sliding block is prevented from sliding excessively to cause damage to equipment.
Description
Technical field
The utility model relates to a kind of reducing mechanism of spring machine, belongs to coiling machine mechanical field.
Background technology
Coiling machine is the plant equipment of producing spring, and steel wire is line sending from coil holder, first passes through alignment, and then steel wire carries out wind spring reducing, finally by cutting knife, has cut off the making of a spring.
Diameter changing mechanism is the critical component in wire spring winding machinery, in spring winding process, steel wire is forced to send, to a direction, move, must there be the push rod of diameter changing mechanism or roller in several positions and go up from different directions steel wire is pushed, change the direction of advance of steel wire, just can make steel wire coil be coiled into spring, therefore, the improvement of diameter changing mechanism is that the development in spring coiling machine field is played to significance.
At present there is following defect in diameter changing mechanism: 1, little, the screw mandrel of the torsion of motor transmission pushes the defect that power is low, commercially available coiling machine product has partial design to have to add the device of high pulling torque, but irrational problem is designed in location, bring very large inconvenience to installation, maintenance, dismounting; 2, easily occur the problem out of control of sliding during reducing slide block linear slide, slide block upward sliding excessively excessively causes to clash into and damages being fixed on knife rest on slide block gearbox extruding or down sliding.
Utility model content
The utility model object is to solve the deficiencies in the prior art, provides a kind of and increases torsion, screw mandrel pushes power and uses the strong reducing mechanism of spring machine of safe, practical property.
The utility model deal with problems adopt technical scheme be:
A kind of reducing mechanism of spring machine, it comprises: ball screw, reducing slide block, reducing knife rest, described ball screw wears reducing slide block and is threaded with reducing slide block, and described diameter changing mechanism also comprises drive unit, and this drive unit comprises gearbox and servomotor;
In described gearbox, be provided with motor gear and reduction gearing, reduction gearing is fixedly connected with ball screw, and described motor gear engages with reduction gearing;
Described servomotor is arranged on gearbox upper end;
Described reducing slide block side is provided with the postive stop baffle parallel with ball screw, first-class point of this postive stop baffle is provided with three inductive type approach switchs, be respectively upper change point, initial point and lower-limit point, on reducing slide block, be provided with the sensor block that can respond to this inductive type approach switch.
The beneficial effects of the utility model are: thus the utility model engages driving screw mandrel with reduction gearing by motor gear, increased the power that pushes of torsion and the screw mandrel of motor transmission, meanwhile, servomotor is designed in gearbox upper end, facilitate diameter changing mechanism to install, there will not be the problem that causes the tool operation inconvenience such as spanner while installing because of the impact of servomotor position.
And, by be provided with inductive type approach switch on postive stop baffle, on slide block, be provided with the sensor block that can respond to inductive type approach switch, when sensor block arrives upper and lower point of accumulation, reducing slide block stops automatically, has avoided slide block to slide and excessively equipment has been caused to damage.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is top view of the present utility model.
In figure: 1. sensor block, 2. ball screw, 3. reducing slide block, 4. postive stop baffle, 5. drive unit, 51. gearboxes, 51a. motor gear, 51b. reduction gearing, 52. servomotors.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1 and Figure 2, a kind of reducing mechanism of spring machine, it comprises: ball screw 2, reducing slide block 3, described ball screw 2 wears reducing slide block 3 and is threaded with reducing slide block 3, diameter changing mechanism also comprises drive unit 5, and this drive unit 5 comprises gearbox 51 and servomotor 52;
In described gearbox 51, be provided with motor gear 51a and reduction gearing 51b, reduction gearing 51b is fixedly connected with ball screw 2, and described motor gear 51a engages with reduction gearing 51b;
Described servomotor 52 is arranged on gearbox 51 upper ends;
Described reducing slide block 3 sides are provided with the postive stop baffle parallel with ball screw 24, first-class point of this postive stop baffle 4 is provided with three inductive type approach switchs, be respectively upper change point, initial point and lower-limit point, on reducing slide block 3, be provided with the sensor block 1 that can respond to inductive type approach switch.
During use, the motor gear 51a being connected with servomotor 52 drives reduction gearing 51b, reduction gearing 51b and ball screw 2 are fixing, under speed change state, the torsion of same motor is strengthened greatly, ball screw 2 wears reducing slide block 3 and is spirally connected with it, thereby the movement by reducing slide block 3 acts on to pushing of reducing knife rest the effect that plays reducing, simultaneously, servomotor 52 is arranged on to gearbox 51 upper ends, when fixing diameter changing mechanism 1, there will not be the problem that causes the tool operation inconvenience such as spanner while installing because of the impact of servomotor 52 positions.
By be provided with inductive type approach switch on postive stop baffle 4, on reducing slide block 3, be provided with the sensor block 1 that can respond to inductive type approach switch, when sensor block 31 arrives upper and lower point of accumulation, reducing slide block 3 stops automatically, has avoided reducing slide block 3 to slide and excessively equipment has been caused to damage.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of the claims in the present invention.
