Description

Friction type roller way

Technical Field

The utility model relates to a roll table, especially a friction formula roll table.

Background

With the continuous development of automatic industrial production, many production enterprises can purchase a plurality of automatic devices to realize different processing and production requirements, and the devices are connected by adopting conveying lines such as roller tables and the like, and the roller tables can convey workpieces from one station to another station; however, in the actual production process, if the previous step is not completed for various reasons, the subsequent workpieces need to be temporarily stopped to be cached on the roller bed; if the workpiece is merely stopped and the rollers in direct contact with the workpiece are still rotating, marks may be left on the surface of the workpiece, so that the rollers supporting the workpiece cannot move relative to the workpiece when the workpiece is stopped.

The traditional roller way for conveying the workpieces is difficult to solve the problems, so that a tray is mostly placed below the workpieces, the roller is directly contacted with the tray, and when the material blocking mechanism blocks the tray, the roller is rubbed with the bottom of the tray, so that the workpiece is protected.

However, the above method requires a tray, which increases a part of the cost. There is therefore a need for a method or apparatus that can remedy the above-mentioned problems.

Disclosure of Invention

The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed can realize the friction formula roll table of work piece buffer memory under the circumstances of not shutting down.

The technical solution of the utility model is that: the utility model provides a friction formula roll table, includes support 1, its characterized in that: support 1 is last to rotate through bearing 2 and to support has a plurality of pivot 3 that are parallel to each other and equidistance distributes, 3 last keys connection of pivot has gyro wheel 4, the tip of pivot 3 is provided with driven sprocket 5, driven sprocket 5 links to each other with drive sprocket through driving chain 6, drive sprocket set up on driving motor's work end, driving motor then set up in support 1, driven sprocket 5's both sides are provided with respectively and cup joint interior friction disc 7 and the outer friction disc 8 in pivot 3, interior friction disc 7 is connected with pivot 3 through round pin axle 9, and interior friction disc 7 is located between driven sprocket 5 and the bearing 2, the threaded connection of end department of pivot 3 has adjusting nut 10, has cup jointed spring 11 in pivot 3 between adjusting nut 10 and outer friction disc 8.

Compared with the prior art, the utility model, have following advantage:

the friction type roller way with the structural form is simple in structure, ingenious in design and reasonable in layout, and a special roller way structure is designed aiming at the problems of a traditional roller way or a traditional conveying line in the working process. The transmission device utilizes two friction plates to be clamped on a chain wheel, and realizes the transmission of torque under the normal working state through the friction force between the two friction plates. And once the stopping mechanism works and stops in front of the workpiece, the friction force between the chain wheel and the friction plate is not enough to drive the rotating shaft to rotate continuously, so that the rotating shaft and the roller cannot rotate, and the chain wheel idles. The structure can stop the workpiece on the roller way at any time, and the problem that the surface of the workpiece is scratched due to relative movement between the roller and the workpiece is avoided. The friction roller way is simple in manufacturing process and low in manufacturing cost, so that the friction roller way has multiple advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.

Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 and 2: the utility model provides a friction formula roll table, includes support 1, rotates through bearing 2 on support 1 and supports the pivot 3 that has a plurality of mutual parallels and equidistance and distributes, the key joint has gyro wheel 4 on pivot 3, the tip of pivot 3 is provided with driven sprocket 5, driven sprocket 5 links to each other with drive sprocket through driving chain 6, drive sprocket set up on driving motor's work end, driving motor then set up in support 1, driven sprocket 5's both sides are provided with respectively and cup joint interior friction disc 7 and the outer friction disc 8 in pivot 3, interior friction disc 7 is connected with pivot 3 through round pin axle 9, and interior friction disc 7 is located between driven sprocket 5 and the bearing 2, the threaded connection of end department of pivot 3 has adjusting nut 10, has cup jointed spring 11 in pivot 3 between adjusting nut 10 and outer friction disc 8.

The utility model discloses friction formula roll table's working process as follows: under the normal working state, under the action of the spring 11, the driven sprocket 5 is clamped by the inner friction plate 7 and the outer friction plate 8 from two sides, and the static friction force between the inner friction plate and the outer friction plate can ensure that when the driven sprocket 5 rotates, the rotating shaft 3 can be driven to rotate together, so that the roller 4 is driven to rotate, and the roller 4 can drive a workpiece supported by the roller 4 to move on a roller way;

when some problems occur at the station in the front direction, the stopping mechanism on the roller way extends out to stop in the advancing direction of the workpiece, at this time, the rotating shaft 3 does not continue to rotate, and the driven chain wheel 5 and the rotating shaft 3 rotate relatively (a bearing is arranged between the driven chain wheel 5 and the rotating shaft 3 to enable the driven chain wheel 5 and the rotating shaft 3 to rotate relatively), namely, the driven chain wheel 5 idles at this time, rotates relatively with the two friction plates, and the rotating shaft 3 does not rotate;

after the stopping mechanism is returned, under the action of friction force, the two friction plates and the driven chain wheel 5 rotate relatively, so that the rotating shaft 3 is driven to rotate continuously;

in actual operation, springs with different specifications or hardness can be selected, and the positive pressure exerted by the two friction plates on the driven sprocket wheel 5 (namely, the friction force between the two friction plates) can be adjusted by rotating the adjusting nut 10 and changing the specific position of the adjusting nut at the end of the rotating shaft 3.
