Abstract
The invention provides a movable pre-stretching device for a chain, which has the characteristics of stable pre-stretching value, large extension amount after stretching and high machining efficiency. The device comprises a chain feeding chain wheel, a stressing chain wheel and a chain discharging chain wheel on which the chain is wound in turn, wherein a stressing chain wheel shaft sleeved with the stressing chain wheel can be arranged on a stressing chain wheel seat in a way of moving along a radial direction. By changing position the stressing chain wheel, the pre-stretching value is changed and the pre-stretching value is stable, so the problems of unstable pre-stretching value and low machining efficiency caused by manual operation are solved.
Description
Technical field
The present invention be a kind of be applied to chain product assembling after, eliminate a kind of loading movable pre-stretching device in the gap that produces in the production process, have performance simple and reliable, that the power value is steady, easy and simple to handle.
Background technology
Former chain Assembling Production needs saving by under the assembler after the assembling, carries out the quiet prestretching of craft then, and pre-pulling method is simply backward, pretension value instability, and artificial factor influence is bigger, and the elongation after drawing is about 0.30mm, and efficient is low, and labor strength is big; Everyone per tour is drawn about 1800.Also because pretension value instability, the elongation after drawing is less, cause chain to be sold after, in use elongation is big and occur reprocessing once more.
Summary of the invention
The movable pre-stretching device for chain that the purpose of this invention is to provide a kind of pretension value stabilization, the elongation after drawing is big, working (machining) efficiency is high.
This movable pre-stretching device for chain comprises being used to walk around advancing chain sprocket wheel, afterburning sprocket wheel, going out the chain sprocket wheel of chain successively that the afterburning sprocket shaft of the afterburning sprocket wheel of suit can radially be arranged on the afterburning chain pulley seat movably.
The present invention is by the position of the afterburning sprocket wheel of change, thus change pretension value, and the pretension value stabilization, change manually-operated pretension value instability, the problem that working (machining) efficiency is low.
In order to reflect the pretension value accurately, it also comprises the sprocket wheel of weighing with chain engages, and the weigh sprocket shaft of weighing of sprocket wheel of suit slide to be provided with on the chain pulley seat of weighing, fixing LOAD CELLS on the chain pulley seat of weighing, and LOAD CELLS links to each other with the sprocket shaft of weighing.Can reflect the pretension value by LOAD CELLS.LOAD CELLS belongs to prior art.
Afterburning sprocket shaft can radially be arranged on structure on the afterburning chain pulley seat movably to be had multiplely, and for example, afterburning sprocket shaft is arranged on the slide block that can slide with respect to afterburning chain pulley seat, is hinged on the slide block with the screw rod end that afterburning chain pulley seat becomes to be threaded.By rotating screw bolt, slide block is and the afterburning sprocket shaft on it moves together.
As improvement, it also comprises the driven sprocket with chain engages.
As improvement, advance the chain sprocket wheel and go out the chain sprocket wheel to be separately fixed at into sprocket and to go out on the end face of sprocket, advance sprocket and go out sprocket and all mesh with driving gear.Can realize into chain sprocket wheel and the synchronous rotation that goes out the chain sprocket wheel by simple structure like this.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
Fig. 2 drives the chain sprocket wheel and goes out the structural representation of the synchronous rotation of chain sprocket wheel.
The specific embodiment
See this movable pre-stretching device for chain shown in Figure 1, comprise being used to walk around advancing chain sprocket wheel 1, the sprocket wheel 2 of weighing, first driven sprocket 3, afterburning sprocket wheel 4, second driven sprocket 5, transition sprocket wheel 6, going out chain sprocket wheel 7 of chain 22 successively.
Afterburning sprocket shaft 8 is arranged on and can be hinged on the slide block with screw rod 11 ends that 10 one-tenth of afterburning chain pulley seats are threaded with respect to afterburning chain pulley seat along on the slide block that radially slides 9 of afterburning sprocket wheel, and screw rod 11 other ends are runner 12 fixedly.By rotating screw bolt, slide block promptly and the afterburning sprocket shaft on it, afterburning sprocket wheel together along the moving radially of afterburning sprocket wheel, thereby the size of change pretension value.
The weigh sprocket shaft 14 of weighing of sprocket wheel 2 of suit slides and is provided with on the chain pulley seat 13 of weighing, fixing LOAD CELLS 15 on the chain pulley seat 13 of weighing, and LOAD CELLS links to each other with the sprocket shaft of weighing.The size of pretension value can be measured and reflect to LOAD CELLS.
Advance on the end face that chain sprocket wheel 1 is fixed on sprocket 16 into, go out on the end face that chain sprocket wheel 7 is fixed on out sprocket 17, advance sprocket and go out sprocket and all mesh with driving gear 18.
Driving gear 18 is fixed on the worm gear output shaft 20 of worm gear reducer 19.The input of worm gear reducer 19 links to each other with motor 21.
Motor 21 rotates, and drives worm gear output shaft 20 through worm gear reducer 19 and rotates, and driving gear 18 drives sprocket and goes out sprocket, advances chain sprocket wheel 1 and goes out chain sprocket wheel 7 and rotate synchronously.The chain 22 of in bundling after the assembling is passed through in this device, regulate runner 12 and adjust loading force by afterburning sprocket wheel, the size of power value is reflected by LOAD CELLS, can visual control adjustment, chain passes through stably by the direction of working motion shown in the arrow among Fig. 1 in this device, has born the loading of afterburning sprocket wheel.
Chain after the improvement is assembled into continuous production, carries out the moving prestretching of machinery and save down behind roller, and pulling force power value is steady, and can adjust, chain is stressed evenly in the prestretching process, draws the back elongation about 0.45mm, significantly reduce the initial stage elongation, favourable improving the quality of products; Prestretching is a mechanical system, and everyone per tour is drawn about 2400, has improved production efficiency, has alleviated working strength of workers simultaneously, improves work efficiency 33%.Result of use of the present invention is clearly, and is simple to operate, realizes machine work, complete instead of manual prestretching, and the power value is steadily safe and reliable, and the elongation of minimizing initial stage is improved the quality of products, and can enhance productivity, and has alleviated labor strength, reaches the effect that reduces cost.
