Abstract
The utility model relates to a friction feed roller which is matched in a loading device on an automatic production line of automobile U-shaped beams and belongs to the field of auxiliary machining devices. The friction feed roller comprises a friction feed roller body driven by a motor, wherein a guide rail is arranged on a stander on the lower side of the friction feed roller body; the friction feed roller body and the motor are in sliding connection with the guide rail through a support; one side of the outer edge of the friction feed roller body is in pressing fit with the surface of a U-shaped beam through jacking the other side of the friction feed roller by an air cylinder; the friction feed roller body comprises a steel wheel positioned in the core part and a friction layer covering the outer edge of the steel wheel; the surface of the friction layer is uniformly provided with a plurality of chutes. Due to the adoption of the structure, as the surface of the friction feed roller body is provided with the chutes, the friction coefficient of the surface of the friction layer can be increased, and the surface tension is reduced, thus the phenomenon that materials cannot be smoothly conveyed due to slip caused by oil stains on the surface in the material conveying process of the U-shaped beam is avoided.
Description
Technical field
The utility model relates to machine up relevant equipment field, particularly matching used friction feeding roller in a kind of feeding device of car U-shaped beam automatic production lines.
Background technology
The automatic charging device that car U-shaped beam automatic production line adopts, need to carry out auxiliary feeding work by friction pay-off, its principle of work is for passing through cylinder-pressing friction roller and U-shaped beam friction of rolling, then by motor, rotarily drive friction roller and rotate, friction roller rotarily drives U-shaped beam and travels forward.This common friction roller of the prior art is circular ladle polyurethane structure, and in use, if U-shaped beam surface exists greasy dirt, thereby friction roller just there will be skidding cannot drive U-shaped beam motion.
Utility model content
The problem that the utility model exists pin prior art, provides a kind of friction coefficient that increases, and reduces capillary friction feeding roller, to prevent causing the problem of feeding smoothly because surface exists greasy dirt to skid in U-shaped beam feeding.
The purpose of this utility model is to realize like this, a kind of friction feeding roller, comprise by motor-driven friction feeding roller, the frame of described friction feeding roller downside is provided with guide rail, described friction feeding roller and motor are by bearing and guide rail sliding block joint, described friction feeding roller outer rim one side is pressed opposite side and U-shaped beam surface pressure flush fit by cylinder top, and described friction feeding roller comprises the steel wheel of core and the friction layer of steel wheel outer rim parcel, and described friction layer surface uniform is provided with some skewed slots.
Friction feeding roller of the present utility model, on friction feeding roller surface, oblique notch, electric machine rotation drives friction feeding roller to rotate, friction feeding roller surface and U-shaped beam force fit, the greasy dirt on U-shaped beam surface is squeezed into skewed slot, can prevent from forming oil film between the mating surfaces of friction feeding roller and U-shaped beam and occurs skidding; And after oblique notching in friction feeding roller surface, can destroy its surface tension, when friction feeding roller be subject to cylinder when pushing with the distortion increase of U-shaped beam contact site with enlarge active surface, thereby further increase the friction coefficient between its contact surface, the pay-off that makes to rub has the also feeding smoothly of situation of greasy dirt at the surface of the work of carrying, obviously improve the reliability of device.
For further improving the friction coefficient on friction roller surface, described skewed slot is the double spiral groove of the intersection that rotation direction is contrary.
As a kind of preferred version of the present utility model, described friction layer is polyurethane encapsulate layer.
Accompanying drawing explanation
Fig. 1 is the structural representation of friction pay-off of the present utility model.
Fig. 2 is the block diagram of friction feeding roller.
Fig. 3 is the structural representation of friction feeding roller
Wherein, 1 friction feeding roller; 101 steel wheels; 102 friction layers; 103 skewed slots; 2 U-shaped beams; 3 motors; 4 cylinders; 5 guide rails.
The specific embodiment
As shown in Fig. 1-3, for friction feeding roller of the present utility model, comprise the friction feeding roller 1 driving by motor 3, the frame of friction feeding roller 1 downside is provided with guide rail 5, friction feeding roller 1 and motor 3 are by bearing and guide rail 5 sliding block joints, friction feeding roller 1 outer rim one side is pressed opposite side and U-shaped beam 2 surface pressure flush fits by cylinder 4 tops, wherein, cylinder block and fuselage are fixed, U-shaped beam 2 supports and is arranged on conveying roller, friction feeding roller 1 comprises the steel wheel 01 of core and the friction layer 102 of steel wheel 101 outer rim parcels, friction layer 102 surface uniforms are provided with some skewed slots 103, in the present embodiment, skewed slot 103 is the double spiral groove of the intersection that rotation direction is contrary, friction layer is polyurethane encapsulate layer.
Friction feeding roller of the present utility model surface oblique notches 103, motor 3 rotating drive friction feeding rollers 1 rotate, friction feeding roller 1 surface and U-shaped beam 2 force fit, the greasy dirt on U-shaped beam 2 surfaces is squeezed into skewed slot 103, can prevent from forming oil film between the mating surfaces of friction feeding roller 1 and U-shaped beam 2 and occurs skidding; And oblique notch after 103 in friction feeding roller 1 surface, can destroy its surface tension, when friction feeding roller 1 is subject to cylinder 4 pushing with the distortion increase of U-shaped beam 2 contacts site with enlarge active surface, thereby further increase the friction coefficient between its contact surface, the pay-off that makes to rub has the also feeding smoothly of situation of greasy dirt at the surface of the work of carrying, obviously improve the reliability of device.
The utility model is not limited to above-described embodiment; every on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the scope of the utility model protection.
