Abstract

The utility model relates to a friction drive type roller machine, wherein a driving unit is constituted by a roller machine frame, a speed reducing motor, a friction drive wheel and a compacting wheel, a set of short rollers mounted on the side board is taken as the support of the sled body, the support for short roller is mounted on the roller machine frame, and a rolling bearing is installed in the roller, legs whose height and levelness can both be adjusted are provided on the lower part of the roller machine frame; a friction wheel is mounted on the output shaft of the speed reducing motor, the speed reducing motor is fixed on a floating base supported by the speed reducing motor; a compacting wheel is mounted relative to the friction wheel. In a non-working status, the gap between the friction wheel and compacting wheel is smaller than the width of the longitudinal girder of the sled body. When the sled body passes through, the friction wheel is extruded out, the spring is compressed, and the elastic force of the spring compacts the longitudinal girder of the sled body between the friction wheel and the compacting wheel. A friction driving force is generated when the friction wheel rotates, to drive the sled body to operate. The utility model has features of saved material, small operation resistance, no noise, no pollution and low energy consumption.

The specific embodiment

For further understanding summary of the invention characteristics of the present utility model and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1-Fig. 4.

As shown in Figure 1 and Figure 2: roll bed frame and form by the end plate 2 of the Z-shaped side plate 1 of pair of straight, a pair of inside bending, the connecting panel of the straight Z-shaped side plate 1 of pipe link 3 and two ends, side plate 1, end plate 2 and pipe link 3 use bolt (or rivet) to be fixed into one respectively, two are rolled usefulness pipe link 3 connections between the side plate 1, can improve the rigidity that integral body is rolled bed frame; Supporting leg 4 is made up of A support 5, adjusting screw(rod) 6 and nut 7, supporting leg 4 by pressing plate 8 usefulness bolts with roll bed frame and captive joint, be whole height and the level attitude that rolls bed frame of scalable by turning adjusting screw(rod) 6 and nut 7; Inboard at side plate 2 is fixed with actuating device, this actuating device includes reducing motor 9, motor base 10, friction wheel 11, contact roller 12 and spring 13,10 fens two parts of motor base, a part be fixed part it be connected with side plate 2 by fixed mount 14 usefulness bolts, another part is a floating part, be rotationally connected A bearing 17 places of two end supports in fixed mount 14 of little axle 16 with fixed mount 14 by the little axle 16 of B support 15 usefulness that is fixed together with motor base 10; Friction wheel 11 is fixed on the shaft of reducing motor 9; Contact roller 12 and friction wheel 11 relative installations, the center of contact roller 12 has the hole, flush fit has B bearing 18 and penetrates A mandrel 19 in its hole, the two end supports of A mandrel 19 is on B bearing 18, contact roller 12 is fixed on the side plate 1 by C support 20, under off working state, the gap between friction wheel 11 and the contact roller 12 is less than the width of sledge body 25 longerons.When sledge body 25 passes through, friction wheel 11 can be swung around fixed mount 14 by little axle 16 by the crowded reducing motor 9 that then is fixed on the B support 15 that floats of opening, at this moment, spring 13 is compressed, and the bounce of spring 13 compresses sledge body 25 longerons between friction wheel 11 and contact roller 12.Motor 9 drives friction wheel 11 rotations when starting. and the rotation of friction wheel 11 will produce friction force and produce, and the friction force of along continuous straight runs moves the sledge body 25 that driving is supported on each roller 21; The live roll assembly includes roller 21, roller bearing 22, B mandrel 23 and C bearing 24, roller bearing 22 usefulness bolts are connected with side plate 1, the center of roller bearing 22 has and wears B mandrel 23 in the hole, one end of B mandrel 23 is fixed in the hole of roller bearing 22, B mandrel 23 is maintained static, the other end flush fit C bearing 24 of B mandrel 23, open-blind hole, the center gland of roller 21 are supported on many group rollers 21 as the prying body 25 of workpiece on the outer ring of C bearing 24.When starting working,,, drive sledge body 25 by originally rolling bed so reducing motor 9 starts when sledge body 25 moves its heads near friction wheel 11 because of on the motor base 10 photoelectric detection switch being installed.When sledge body 25 afterbodys and friction wheel 11 disengaged, reducing motor 9 shut down.

Advantage is: cancelled cog belt, and the resistance that produces when having eliminated the cog belt engagement, so the friction-driven formula is rolled bed accessory and saving in material arranged, little, the characteristic of low energy consumption of running resistance.Can in the normal temperature working environment, be applied to general conveying of sledge body (workpiece) and technology and carry.
