Abstract
The utility model discloses an inertia transmission main shaft of a nut conveyor, which has the advantages of high speed. The embedded nut has high accuracy and the function of automatically regulating the target when the positioning pin is lands on the ground. One main shaft can simultaneously fit with nuts of more than two specifications and has the advantages of high degree of standardization. In the technical proposal of the inertia transmission main shaft of the nut conveyor, the front end of the main shaft is provided with a thin neck which is 25 to 35mm long, and the gap between the thin neck and the inner hole of the nut is 1 to 4mm.
Description
Technical field
The utility model relates to a kind of conveying main shaft, carries main shaft more specifically to a kind of inertia of nut conveyer.
Background technology
With the supporting nut conveyer of projection weld machine, when being transported to nut on the electrode, realize by the cylinder crank motion.Carry the slender rod piece of nut on the cylinder piston rod, be referred to as conveying lever or main shaft traditionally.As Fig. 1 is magnetic main axle structure scheme drawing.The magnetic main shaft is to rely on magnetic attraction, the main shaft of constraint as its name suggests.10 millimeters of front end of spindles, with 100 millimeters of rear ends be non-magnet material, 180 millimeters of middle-ends are made for permeability magnetic material.The main shaft on the go will accurately and stably be transported to nut on the electrode locating dowel pin, must carry out nut: fixed constraint.Nut machine product fixed constraint way common on the market has: magnetic attraction; The air-flow locking; Vacuum attraction etc.Being used for maximum is magnetic attraction, and magnetic source has the branch of electromagnet and permanent magnet.As Fig. 2, in the motion, main shaft middle-end permeability magnetic material conduction magnetic force holds nut, and after nut arrived assigned address, the magnetic conduction position broke away from magnetic source, and nut comes off, and finishes conveying.This mechanism can stably be transported to nut accurate position, and delivery speed is adjustable, and the rate of being up to the standards is easy to reach 100% purpose.But have stability problem, promptly the client what some can occur and fall nut in use for some time, card nut phenomenon.Reason has four:
1, the nut of the most advanced and sophisticated absorption of main shaft is made the time spent nut and is come off easily being subjected to external force (door closure).
2, main shaft is most advanced and sophisticated little with the nut inner hole gap, embeds probability and reduces with nut precision attenuating in stop place in passage.
3, permanent magnet magnetic force can be decayed with the interference of the alternating electric field of projection weld machine.
4, spindle deformation also can have influence on and carry nut accurately to land on the locating dowel pin.
In addition, the magnetic spindle material is welded by three sections, requires the welding technique height, relies on import welding blank.The working accuracy height, technology cost height.The Chinese automobile manufacture of today, also to weld simultaneously other as: circular nut, hexagonal nut, rhombus nut, trapezoidal nut etc., this has higher requirement to carrying main shaft.
Summary of the invention
The purpose of this utility model is to solve deficiency and the problem that exists in the above-mentioned present technology, provides a kind of inertia of nut conveyer to carry main shaft.
The utility model is achieved through the following technical solutions:
The inertia of nut conveyer of the present utility model is carried main shaft, and it is 25～35 millimeters thin neck that its described front end of spindle is provided with length, and carefully the gap of neck and nut inner hole is 1～4 millimeter.
The inertia of nut conveyer of the present utility model is carried main shaft, and it is 20 °～55 ° that the inertia of its nut conveyer is carried main shaft itself and horizontal sextant angle when carrying nut.
The inertia of nut conveyer of the present utility model carries its principle of main shaft to be: when the cylinder conveying mechanism is carried nut, be about 20 °～55 ° with horizontal sextant angle, nut can produce one with motion of main shaft the time: the acceleration/accel that partical gravity Pcos (20 °～55 °) forms.Utilize the principle of inertia of particle barodynamics dexterously, reasonable consideration cylinder piston rod motion process, front end of spindle design length is 25～35 millimeters thin neck, makes the nut that embeds neck can not be touched down promptly that (neck is weak point more, more easily touches down by door closure; The gap is bigger, more easily touches down), cylinder can not be broken away from again when slowing down in advance, rationally increases the gap (1～4 millimeter) of thin neck of main shaft and nut inner hole simultaneously, makes it easy inserted num.
The utility model compared with prior art has following beneficial effect:
The inertia of nut conveyer of the present utility model carries main shaft to have fireballing characteristics; Inserted num accuracy rate height has the function of automatic compensation target position when locating dowel pin lands; Can make a main shaft be suitable for two or more specifications of nuts simultaneously, have the high characteristics of standardization level; Because the gap is big, has reduced precision, reduce the technology cost; Cancel magnet assemblies, simplified mechanism; What use is a kind of material, does not reimportation blank, reduces material cost.

The specific embodiment
Embodiment
As shown in Figure 3 and Figure 4, it is 35 millimeters thin neck 3 that the inertia of nut conveyer of the present utility model carries main shaft, its described main shaft 2 front ends to be provided with length, and the gap of thin neck 3 and nut inner hole is 2 millimeters.It is 40 ° that the inertia of nut conveyer of the present utility model is carried main shaft itself and horizontal sextant angle when carrying nut.
During work: the motion starting stage, main shaft carries out the transition to uniform movement by accelerated movement, can smoothly nut be embedded into the neck root.After-stage, motion of main shaft stops by decelerating to, and during deceleration, the neck of lengthening still can effectively stop nut to be deviate from, and when main shaft stops, yet nut relies on inertia Zi on the electrode locating dowel pin that accurately lands.
In implementation process, though based on high-frequency work tempo, nut is easier to wearing and tearing to the thin neck ratio of main shaft, and the inertia of nut conveyer of the present utility model carries the main shaft design service life to reach more than 60000 times.
Claims (2)
1, a kind of inertia of nut conveyer is carried main shaft, it is characterized in that it is 25～35 millimeters thin neck that described front end of spindle is provided with length, and carefully the gap of neck and nut inner hole is 1～4 millimeter.
