Abstract

The utility model discloses a device for running-in and pre-stressing of chains, which mainly comprises a machine body; a motor is arranged in the machine body; the motor is connected with a worm speed reducer; at least five sprockets are matched with the surface of the machine body; each of the sprockets is composed of a sprocket shaft and a sprocket cover; a gear is also arranged on the same sprocket shaft; the motor drives the gear through the worm speed reducer and drives the gear on a next sprocket shaft to achieve the goal that the whole device for running-in and pre-stressing of chains is started; pretension is adjusted through adjusting a pressure spring; the utility model is especially provided with a pull force sensor, a pressure sensor and a digital indicator. The utility model is suitable for running-in and pre-stressing for tooth-shaped chains, roller chains, bush chains and chains with other forms.

Description

The chain running-in, give drawing device

The utility model relates to the chain running-in, gives drawing device.

Present all kinds of chains that in industrial, communications and transportation, use, since the chain product before dispatching from the factory through the chain running-in, give and PROCESS FOR TREATMENT such as draw, so new chain is through after a while use, to elongate appear in chain easily, loosening, influenced result of use and product quality.

It is a kind of reasonable in design, simple in structure, easy to use that the purpose of this utility model is to provide, and has good running-in, gives the chain running-in of drawing effect, gives drawing device.

The utility model is the chain running-in, give drawing device, for achieving the above object, the utility model mainly is made up of body, motor, worm reducer, also comprise at least 5 sprocket wheels being located on the body, place in the body with the same sprocket shaft of sprocket wheel, play the gear of gearing and draw, pressure sensor and digital display meter, the stage clip that places being used on the body to stablize loading force is in addition formed.Described sprocket wheel also comprises the sprocket shaft that places centre of sprocket and places the bearing cap on the sprocket wheel to form that described stage clip also comprises stage clip cushion block and stage clip pull bar composition.

The utility model compared with prior art has following distinguishing feature and good effect.1, the utility model stretched to the chain that the assembles initial stage of carrying out, and reduced elongation when chain is used in the early stage, improved the quality of products.2, by the chain running-in, give and drawing, can reduce or eliminate when chain is just adorned the burr that exists or slightly die for the sake of honour, improve chain flexibility in actual use.3, the utility model is as long as change the profile of tooth of sprocket wheel, can be applicable to the chain running-in of silent chain, roller chain, bush(ing) chain and other form and gives and drawing, and is of many uses.4, the utility model also can use simultaneously with chain Short Item testing fixture.The utility model is that chain is made special equipment, uses the chain manufacturing.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 5 is the utility model agent structure plane D-D cutaway view.

As shown in Figure 1, the utility model body 18 work tops are provided with at least 5 sprocket wheels 1, Figure 1 shows that 7 sprocket wheels 1, and sprocket wheel 1 is provided with bearing cap 2, is fixed on the sprocket shaft 3.In order to guide the chain dish to go into each sprocket wheel 1, carry out running-in and give and drawing, be provided with feed lead rail 4 and guide pad 5 specially at charging aperture, be provided with discharging guide rail 6 and discharging guide pad 7 at discharging opening.Shown in Fig. 2,3, in body 18, be provided with motor 11, motor 11 connects worm reducer 14, and worm reducer 14 links to each other with gear 17 by the

shaft coupling

15,16 on the sprocket shaft 3.

As Fig. 3, shown in 4, when the utility model starts use, press the motor starting control knob earlier, during motor 11 runnings, by motor 11 the axle with worm reducer 14 power shafts on one group of

shaft coupling

12,13, worm reducer 14 is started working, again by one group of shaft coupling 15 on worm reducer 14 output shafts and the

sprocket shaft

3,16 connect, also be provided with gear 17 on the sprocket shaft 3, gear 23 engagements on this gear 17 and the axle 22 of passing a bridge, be meshed with gear 17 on another sprocket shaft 3 by the gear 23 of axle 22 of passing a bridge, drive each relevant sprocket shaft 3 and sprocket wheel 1 like this, reach the whole running-in of drive, giving drawing device starts working.

Giving the adjustment of pulling force, is to adjust by the stage clip 8 of stablizing loading force.Described stage clip 8 also comprises stage clip cushion block 9 and stage clip pull bar 10, and in the running-in of chain, give and being pulled through in the journey, when chain pitch had minor variations, then pressured spring 8 was done suitably flexiblely to adjust and keep giving the stable of pulling force.

As shown in Figure 5, for faster, show the numerical value give pulling force better, the utility model also is provided with specially and draws, pressure sensor 19 and digital display meter 24, draw, pressure sensor 19 is that adjustment by nut 21 and screw rod 20 realizes, draw by being connected again, the digital display meter 24 on the pressure sensor 19 shows.For draw, the size of pressure can be correctly, show intuitively, thereby according to the numerical value that display 24 shows, in time adjust stage clip pull bar 10, adjust the chain running-in, give the effect of drawing realizing.

Chain running-in of the present utility model, give drawing device, can also with the supporting use of chain assembly machine.Electric or mechanical type chain Short Item testing fixture also can be set on the zone that chain passes through, just can reach the chain running-in simultaneously, give the purpose of drawing and checking Short Item.

The utility model is applicable to the chain manufacturing, be specially adapted to the chain of silent chain, roller chain, bush(ing) chain and other form running-in, give and drawing.
