Abstract
The invention provides a combined spring comprising a pull rod (1), a choke ring (2), a pressure spring (3) and a tension spring (4). The combined spring is characterized in that the pressure spring (3) is sleeved in the tension spring (4), the choke ring (2) is connected with the inner upper end face of the pressure spring (3) and the outer upper end face of the tension spring (4), the pull rod (1) penetrates through the choke ring (2) and the pressure spring (3) to be connected with the pressure spring (3), and one end of the pull rod (1) extends out of the choke ring (2) while the other end of the pull rod (1) is connected with the outer lower end face of the pressure spring (3). The combined spring is capable of transforming the performances of two kinds of springs in a numerical control mechanism, thereby equipment is simpler.
Description
One, technical field
The present invention relates to a kind of spring, particularly a kind of cluster spring is fit to digital control processing and uses
Two, background technique
Extension spring is the helical spring that bears axial tension, generally make with circular section material spring steel, when not bearing load, between the circle of extension spring and the circle generally all be and tight very close to each other, utilize spring-back force (pulling force) work after stretching, in order to the size of the motion of controlling parts, storage or saving energy, measuring force etc., most extension spring usually under tension force to a certain degree, even without any the situation of load under.This initial tension force has determined in the situation without any load, the tightness degree of extension spring coiling.Extension spring is widely used in the protection hardware, control valve for fluids, mechanical space flight parts, actuator, switching device machine, instrument of medical breathing apparatus, motion control, medical mobile device, manual tool, home care apparatus, damping, pump spring, machinery and electronics.
Along with automation and integrated fast development; the processing of a workpiece usually can once be finished from the blank to the finished product; this will run into different processing environments; the power suffered at different processing environments is not identical yet; when the stressed difference of institute is little, can use common extension spring; but when suffered pulling force difference was huge, common extension spring can't adapt to the variation of processing environment, make automatic integratedization be processed into can not or process equipment more complicated.
Three, summary of the invention
The objective of the invention is to invent a kind of cluster spring that can in different stretch length, change the elastic coefficient, can cooperate numerical control device restrained stretching length, workpiece is worked under different pulling force environment.
Cluster spring of the present invention comprises pull bar, choke ring, stage clip and extension spring is characterized in that compression spring sleeve in extension spring, and choke ring connects stage clip upper end interior edge face and exterior edge face, extension spring upper end, pull bar passes choke ring and stage clip, and an end extends outside the choke ring, and the other end is connected with exterior edge face, stage clip lower end.
The external diameter of stage clip is less than the internal diameter of extension spring, and pull bar can be freely movable in choke ring and stage clip, and choke ring is connected stiff with the extension spring upper end.
Cluster spring of the present invention, the parameter of its stage clip, extension spring, choke ring, pull bar can design according to actual needs.
During stretching, pull bar tension and compression spring, stage clip is compressed, the elasticity coefficient of numerical control cluster spring is the stack of stage clip and extension spring, after stage clip is pressed onto the end and lost efficacy, the numerical control cluster spring again by choke ring take the elasticity coefficient of extension spring as main, thereby can change pulling force by how much orders of magnitude, thereby adapt to different processing environments.
The performance of cluster spring of the present invention two kinds of springs of energy conversion in a cnc mechanism, thus make equipment simpler.
Four, description of drawings
Accompanying drawing is a kind of embodiment's of cluster spring of the present invention structural representation.Among the figure, the 1st, pull bar, the 2nd, choke ring, the 3rd, stage clip, the 4th, extension spring.
Five, embodiment
Referring to accompanying drawing, cluster spring of the present invention is by pull bar 1, choke ring 2, stage clip 3 and extension spring 4 form, stage clip 3 is enclosed within the extension spring 4, and choke ring 2 connects stage clip 3 upper end interior edge faces and exterior edge face, extension spring 4 upper end, and pull bar 1 passes choke ring 2 and stage clip 3, one end extends outside the choke ring 2, and the other end is connected with exterior edge face, stage clip 3 lower end.
In the practical application, the performance of cluster spring of the present invention two kinds of springs of energy conversion in a cnc mechanism.As in the numerical control gem process equipment, the facet jewel that will polish has a lot of faces and forms a beautiful pattern, these faces vary, area differs more than ten times, these faces must just can be ground and polish under certain pressure, and the cluster spring of the present invention as required size of grinding and burnishing surface applies different power and makes them be ground and polish under identical pressure.
