In the figure: 1. a base; 11. mounting holes; 12. a rotating groove; 13. a chute; 2. a swing arm; 3. a rotating shaft; 4. a rack; 5. a gear; 6. a cylinder; 7. a shaft sleeve; 8. a key pin; 9. a connecting member.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, an embodiment of the present application provides an overturning structure, which includes a base 1, wherein a rotating groove 12 and a sliding groove 13 are provided on the base 1, and the sliding groove 13 is located on one side of the rotating groove 12. The rotation of rotating groove 12 is connected with the rotation axis 3 that runs through base 1 in the rotation, the both ends fixedly connected with spiral arm 2 of rotation axis 3, sliding connection has rack 4 in the spout 13, fixedly connected with and rack 4 meshed gear 5 on the rotation axis 3, be provided with the actuating mechanism who is used for driving rack 4 to go up and down on the base 1.

In the course of the work, the flexible rack 4 that drives of output of cylinder 6 goes up and down in spout 13, because gear 5 and rack 4 mesh, 4 lift in-process of rack can drive gear 5 and rotate to can drive radial arm 2 and be the upset motion, gear 5 and rack 4 have the ability of auto-lock, when cylinder 6 does not move, radial arm 2 does not have the rotation for base 1, makes radial arm 2 can stop at arbitrary angle that opens and shuts.

The utility model can meet the use requirement of a larger opening and closing angle in a specific station and has the advantages of high precision, flexible and stable overturning, simple structure and low use cost.

On the basis, the driving mechanism comprises a cylinder 6 and a connecting piece 9, the cylinder 6 is fixedly connected with the base 1, one end of the connecting piece 9 is fixedly connected with the output end of the cylinder 6, and the other end of the connecting piece 9 is hinged to the rack 4.

In the course of the work, the output of cylinder 6 drives connecting piece 9 and stretches out and draws back to drive rack 4 and go up and down, the axiality of connecting piece 9 and rack 4 hardly keeps unanimous in the actual production manufacturing, thereby leads to taking place vibrations between the two easily, influence the stability of mechanism, through articulating connecting piece 9 and rack 4, in the course of the work, can the rotation each other make level in order to realize the self-adaptation between connecting piece 9 and the rack 4, thereby can reach the purpose of proofreading and correct the concentricity.

The technical scheme reduces the vibration generated in the using process of the utility model and effectively improves the stability of the utility model.

On the basis, a shaft sleeve 7 is arranged in the rotating groove 12 in an interference fit mode, and the rotating shaft 3 is rotatably connected in the shaft sleeve 7.

The shaft sleeve 7 is in interference fit in the rotating groove 12, so that relative rotation does not exist between the shaft sleeve 7 and the base 1, the rotating friction force between the shaft sleeve 7 and the base 1 can be reduced, and the rotating shaft 3 is supported and can rotate by the inner ring of the shaft sleeve 7.

Through the setting of axle sleeve 7, reduced the wearing and tearing between axle sleeve 7 and the base 1, strengthened its life, make rotation of rotation axis 3 more nimble stable simultaneously.

On the basis, a key groove is arranged between the gear 5 and the rotating shaft 3, and a key pin 8 is arranged in the key groove.

In the working process, the pin key is used for limiting and locking the gear 5 on the rotating shaft 3, and the rotating shaft 3 can be driven to rotate while the gear 5 rotates.

Through the arrangement of the pin keys, the stability of connection of the gear 5 and the rotating shaft 3 is improved.

On the basis of the above, the base 1 is provided with a mounting hole 11 for mounting it to an external device.

The mounting hole 11 is used to mount the base 1 to an external device.

Through the setting of mounting hole 11 for the installation of base 1 is more convenient, and has better connection stability.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the utility model may occur to those skilled in the art without departing from the principle of the utility model, and are considered to be within the scope of the utility model.
