Abstract

The utility model relates to a non-return device, belonging to a machine tool accessory, in particular to an accessory used to deliver workpieces on a production line. The non-return device comprises conveying rollers. The conveying rollers are rotatably installed at the swinging end of a swinging arm. The swinging arm is rotatably installed on a base through a torsion spring and a shaft. The utility model has the advantages that the structure is novel, the non-return device and the workpiece conveying rollers are effectively integrated into a whole body, the volume is small and the non-return valve can be installed in a small space. When the workpiece passes through the rollers, the rollers drives the swinging arm to rotate under the gravity of the workpiece to smoothly transfer the workpiece forward; after the workpiece passes through the rollers, the swinging arm is recovered and rises up under the reverse drawing force of the torsion spring. The top of the rollers on the swinging arm is higher than the raceway surface to prevent the workpiece from drawing back, so as to realize non-return movement.

Description

Check device

One, technical field:

The utility model relates to machine tool accessories, especially for the annex of production line workpiece conveying.

Two, background technology:

At present, the production line workpiece carries raceway when conveying workpieces, sometimes for preventing that workpiece from stopping to draw back afterwards, employing is provided with check device on production line way solves, and existing most check device adopts gravity principle, complex structure, volume is bigger, can't satisfy in less space mounting, so that the lathe volume is big, has increased taking up room of workshop.

Three, summary of the invention:

The purpose of this utility model is to address the above problem, and a kind of check device is provided, and is simple in structure, volume is small and exquisite, can be in less space mounting.

The technical scheme that the utility model is adopted for achieving the above object is: check device, relate to conveying roller, and roller is rotatably installed in the swinging end of swing arm, and swing arm is rotatably installed on the pedestal by torsion spring and axle.

Described roller end face is higher than swing arm, and swing arm upper roller end face is higher than the raceway plane.

Described roller is rotatably installed on the swinging end of swing arm by wheel shaft.

The utility model novel structure, check device and workpiece conveying roller effectively are combined as a whole, volume is little, has solved the problem of check device in less space mounting, when work is through roller during work, roller is the swing arm rotation under the effect of workpiece gravity, make steadily transmission forward of workpiece, behind workpiece process roller, utilize the anti-pull out force of torsion spring that the swing arm revolution is erected, roller end face in the swing arm is higher than the raceway plane, stops workpiece to be drawn back to realize non-return.

Four, description of drawings:

Fig. 1 is the utility model structural representation.

Fig. 2 is the left view of Fig. 1.

Five, the specific embodiment:

Check device as shown in Figure 1, 2, relate to conveying roller 3, roller is rotatably installed in the swinging end of swing arm 2 by wheel shaft 4, roller 3 end faces are higher than swing arm 2, swing arm upper roller end face is higher than the raceway plane, swing arm is rotatably installed on the pedestal 7 by torsion spring 5 and axle 6, and pedestal 7 is fixed on the base plate that links with the aluminium alloy wallboard.

As shown in Figure 1, workpiece 1 is placed on the raceway roller shaft during work, and when workpiece 1 advances and contacts with roller 3, roller 3 drives swing arm 2 revolutions under workpiece 1 effect, and roller 3 rolls in workpiece 1 bottom surface; Break away from roller 3 when workpiece 1 advances to, roller 3, swing arm 2, wheel shaft 4 attitude that restores to the original state under torsion spring 5 counter-drawing actions plays preventing to return effect behind the workpiece 1.

Claims

1, check device relates to roller, it is characterized in that: roller (3) is rotatably installed in the swinging end of swing arm (2), and swing arm (2) is rotatably installed on the pedestal (7) by torsion spring (5) and axle (6).

2, check device according to claim 1 is characterized in that: the roller end face is higher than swing arm, and swing arm (2) upper roller end face is higher than the raceway plane.
