CN102674078A - Adjustable balance mechanism of winding machine spindle - Google Patents

Abstract

As promotion of requirements for high-speed high-quality processing in winding processing, at present, some spindle rotation speed of a high-speed winding machine arrives 10000 revolutions per minute. In an actual production process, a plurality of special-shaped products are produced. After a special-shaped product is installed on a high-speed winding spindle through a clamp, due to the presence of unbalance amount of manufacturing and installation of the products and the clamp, the spindle rotates unstably so as to influence processing accuracy directly and generate shock and noise. The adjustable balance mechanism of the winding machine spindle is simple in structure, three weight balancing blocks with adjustable circumferential positions are arranged between a shaft sleeve check ring 4 and a movable check ring 2, a balance amount which is equal to the size of a spindle unbalance amount and opposite to the direction of the spindle unbalance amount is obtained through a debugging mode so as to enable a product principal inertia axis 6 to be coincided with a rotation axis 7, and the spindle is balanced. The adjustable balance mechanism of the winding machine spindle can improve winding quality, effectively prolong service life of a spindle bearing of the winding machine, and greatly reduce shock and noise generated in winding.

Description

The adjustable equalizing gear of wire coiling machine main shaft

Affiliated technical field

The present invention relates to the adjustable equalizing gear of a kind of wire coiling machine main shaft.

Background technology

Along with the demand for the processing of high speed high quality in the coiling processing promotes; At present the spindle speed of high speed wire coiling machine some in addition reached 10000RPM, and in actual production process, more special-shaped product is arranged; Be installed to the main shaft that winds the line at a high speed through anchor clamps after; Amount of unbalance existence because of its product itself and anchor clamps manufacturing installation causes main axis rotation unstable, directly has influence on working accuracy and produces and shake and noise.

Summary of the invention

For the vibrations that overcome existing wire coiling machine work in-process and the list of making an uproar, and improve crudy and efficient, the invention provides a kind of dynamically balanced adjustment structure, this structure manufacturing is simple, easy to adjust, has excellent popularization and is worth.

Be the realization above-mentioned purpose, the function of claim 1, it possesses: axle sleeve back-up ring 4, in the function that realizes claim 1, it mainly plays the effect of constraint clump weight axial slip, also plays the function that connects product and main shaft simultaneously.Movable back-up ring 2, it mainly plays the effect of constraint clump weight axial slip, clump weight 3, it is a principal character of the present invention, plays adjustment and improves the dynamically balanced effect of main shaft.Clump weight holding screw 1, it mainly plays the effect that tightens up after clump weight is adjusted to destination locations.

The specific embodiment:

Below, specify the present invention based on accompanying drawing and embodiment.Fig. 1 representes the block diagram in the present embodiment, with convenient understanding directly perceived.But details is expressed and is not very clear.Fig. 2 has showed longitudinal profile of the present invention, the position relation between each element of more clearly performance.Fig. 3 master 3 has explained that mainly the mode of tightening up of the clump weight 3 between axle sleeve back-up ring 4 and movable back-up ring 2 is: after clump weight 3 is adjusted to destination locations; Locking clump weight holding screw 1; Then the shoulder of clump weight 3 can hold out against the inner edge of axle sleeve back-up ring 4 and movable back-up ring 2, tightens up purpose to reach.Fig. 4 has laterally analysed and observe clump weight 3 positions.

Specific embodiment: start wire coiling machine; Main shaft drives mechanism of the present invention and comprises the product rotation; Because main shaft itself reaches the overbalance that product itself and installation error cause, product principal axis of inertia 6 is not overlapped with main axis rotation axle 7; Cause main axis rotation unstable, directly have influence on working accuracy and produce vibrations and noise.Use the present invention to solve this problem step: to unscrew clump weight holding screw 1; It is along the circumferential direction slided, behind the appropriate location, tighten clump weight holding screw 1; It is also fixing with the inner edge of movable back-up ring 2 that then the shoulder of clump weight 3 can hold out against axle sleeve back-up ring 4; This action differs according to operator's skill level number of times, overlaps with main axis rotation axle 7 up to product principal axis of inertia 6, and vibrations have bigger improvement with noise; Then the balance adjusting work of this main shaft is accomplished, up to the production adjustment according to circumstances again of another specification.

Claims (1)

1. between the product of wire coiling machine and main shaft, have quantity be not less than 2 the scalable circumferential position clump weight and improve the main shaft kinetic balance with this.
