Description

Technical Field

[0001] The utility model relates to the technical field of cam turntables, in particular to a double-station roller cam turntable. Background Art

[0002] During the use of the double workstation, one workstation is performing processing while the other workstation is performing unloading and loading. Then, by switching the position of the turntable, the machine at the loading completion position is rotated to the processing workstation. At this time, the other workstation is performing unloading of the raw materials that have just been processed and loading of new raw materials to be processed, thereby realizing the production operation of the double workstation and improving the operating efficiency. In the prior art, in order to improve the stability of the rotation switching of the workstations, the motor is generally provided with a locking structure. Such a motor is generally more expensive, and once damaged, the turntable will still rotate unexpectedly. In order to cope with the above situation, the user will use an external locking structure to limit the turntable. Such an external locking structure design is inconvenient to use. Utility Model Content

[0003] The purpose of the utility model is to provide a double-station roller cam turntable. Through the mutual cooperation of the set driving component and the built-in limit component, there is no need to use a motor with a built-in locking structure. An ordinary motor can be used, thereby reducing the cost of use. In addition, during the rotation switching process, when the rotating shaft stops rotating, automatic locking is achieved on the built-in mechanical structure without the need for an external locking mechanism, thereby avoiding the turntable from rotating accidentally or being pulled, and ensuring the stability of the turntable after rotation.

[0004] The technical solution of the utility model is as follows:

[0005] A double-station roller cam turntable, comprising:

[0006] A drive assembly, the drive assembly comprising a mounting housing, a reducer disposed outside the mounting housing, a motor connected to an input end of the reducer, and a rotating platform disposed above the mounting housing;

[0007] A built-in limiting component includes a cam mechanism connected to the output end of the reducer, a wheel tower arranged in the mounting shell, and a connecting plate connected to the top surface of the wheel tower.

[0008] As a preferred solution of the double-station roller cam turntable described in the utility model, a raised cylinder is fixed on the outer surface of the wheel tower;

[0009] There are a plurality of raised cylinders, and the plurality of raised cylinders are distributed in an annular manner on the outer side wall of the wheel tower.

[0010] As a preferred solution of the double-station roller cam turntable described in the utility model, the cam mechanism includes a long shaft connected to the output end of the reducer and a spiral arc surface connected to the outer surface of the long shaft.

[0011] As a preferred solution of the double-station roller cam turntable described in the utility model, the cam mechanism also includes a straight area axis arranged between the two spiral arc surfaces.

[0012] As a preferred solution of a double-station roller cam turntable described in the utility model, it also includes a connecting component, which includes a first hole position opened on the surface of the connecting disk, a circular groove opened on the bottom surface of the rotating platform and a second hole position opened in the circular groove.

[0013] As a preferred solution of the double-station roller cam turntable described in the utility model, the connecting plate and the circular notch are butted against each other and are locked by a screw passing through the first hole and the second hole.

[0014] The double-station roller cam turntable provided by the utility model has the following advantages:

[0015] By cooperating with each other, the driving assembly and the built-in limit assembly do not need to use a motor with a built-in locking structure, and an ordinary motor can be used, thereby reducing the cost of use. In addition, during the rotation switching process, when the shaft stops rotating, the built-in mechanical structure is automatically locked, and no external locking mechanism is required, thereby avoiding accidental rotation or being pulled of the turntable, and ensuring the stability of the turntable after rotation.

[0016] During specific use, the output end of the motor drives the reducer to rotate, and at this time the reducer drives the long axis to rotate. When the long axis rotates, it will drive the distributed spiral arc surface to rotate. At this time, the spiral arc surface will spirally push the raised cylinder on the outer surface of the wheel tower, and the raised cylinder moves along the surface of the spiral arc surface. In this way, the wheel tower will be driven to rotate, and the rotation switching of the rotating platform can be realized. When the motor stops and the rotating platform is switched, the long axis stops rotating. At this time, the raised cylinder on the outer surface of the wheel tower is located at the position of the axis of the straight area, and the raised cylinder is clamped between two adjacent arc surfaces. In this way, even if someone manually pushes the rotating platform, due to the limited power of manual pushing, it is not enough to make the rotating platform drive the raised cylinder to push the spiral arc surface to flip, so the long axis will not rotate, so the rotating platform can be limited. Only when the motor is started and the motor drives the long axis to rotate through the reducer, the spiral arc surface spirally rotates. At this time, the raised cylinder on the outer surface of the wheel tower can move along the spiral arc surface, driving the rotating platform to rotate and switch. BRIEF DESCRIPTION OF THE DRAWINGS

Further, in order to enable the public to have a better understanding of the present application, some specific details are described in detail in the following detailed description of the present application. Those skilled in the art can fully understand the present application without the description of these details.

[0026] In order to improve the engineering economy, the present utility model provides a double-station roller cam turntable. Through the mutual cooperation of the provided driving assembly and the built-in limiting assembly, there is no need to use a motor with a built-in locking structure, and an ordinary motor can be used, reducing the use cost. And during the rotation switching process, when the rotating shaft stops rotating, automatic locking on the built-in mechanical structure is achieved, without an external locking mechanism, avoiding the situation of accidental rotation or being turned of the turntable, and ensuring the stability of the turntable after rotation.

[0027] The present utility model will be further described below with reference to the accompanying drawings.

[0028] As Figure 1-6 shown, the present utility model is a double-station roller cam turntable, including a driving assembly and a built-in limiting assembly;

[0029] The driving component is used in cooperation with the built-in limiting component. Specifically, the driving component includes the installed mounting housing 11, the speed reducer 12 arranged outside the mounting housing 11, the motor 13 connected to the input end of the speed reducer 12, and the rotating platform 14 arranged above the mounting housing 11;

[0030] In specific use, the built-in limiting component is installed based on the Anzu housing 11, the speed reducer 12, the motor 13 and the rotating platform 14, and the motor 13 is driven.

[0031] The built-in limiting component is used for built-in limiting. Specifically, the built-in limiting component includes the cam mechanism 21 connected to the output end of the speed reducer 12, the wheel tower 22 arranged inside the mounting housing 11, and the connecting disk 23 connected to the top surface of the wheel tower 22;

[0032] A convex cylinder is fixed on the outer surface of the wheel tower 22;

[0033] Among them, a plurality of convex cylinders are provided, and the plurality of convex cylinders are annularly distributed on the outer side wall of the wheel tower 22;

[0034] The cam mechanism 21 includes the long shaft 211 connected to the output end of the speed reducer 12, and the spiral arc surface 212 connected to the outer surface of the long shaft 211; the cam mechanism 21 further includes the linear region shaft 213 arranged between the two spiral arc surfaces 212;

[0035] In specific use, the output end of the motor 13 drives the speed reducer 12 to rotate. At this time, the speed reducer 12 drives the long shaft 211 to rotate. When the long shaft 211 rotates, it will drive the distributed spiral arc surfaces 212 to rotate. At this time, the spiral arc surface 212 will helically push the convex cylinders on the outer surface of the wheel tower 22, and the convex cylinders will move along the surface of the spiral arc surface 212. In this way, the wheel tower 22 will be pushed to rotate, and the rotation switching of the rotating platform 14 can be realized. When the motor 13 stops, when the rotation switching of the rotating platform 14 is realized, the long shaft 211 stops rotating. At this time, the convex cylinders on the outer surface of the wheel tower 22 are located at the position of the linear region shaft 213, and the convex cylinders are clamped between two adjacent arc surfaces. In this way, even if someone manually pushes the rotating platform 14, due to the limited power of manual pushing, it is not enough to make the rotating platform 14 drive the convex cylinders to push the spiral arc surface 212 to flip, so the long shaft 211 will not rotate, and the rotating platform 14 can be limited in this way. Only when the motor 13 is started and the motor 13 drives the long shaft 211 to rotate through the speed reducer 12, the spiral arc surface 212 rotates helically. At this time, the convex cylinders on the outer surface of the wheel tower 22 can move along the spiral arc surface 212 to drive the rotation switching of the rotating platform 14.

[0036] The connecting component is used for connecting to the rotating platform 14. Specifically, the connecting component includes a first hole 31 formed on the surface of the connecting disk 23, a circular notch 32 formed on the bottom surface of the rotating platform 14, and a second hole 33 formed in the circular notch 32;

[0037] In specific use, the connecting disk 23 and the circular notch 32 are docked with each other, and are locked by a screw passing through the first hole 31 and the second hole 33.

[0038] Although the present invention has been described above with reference to the embodiments, however, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way, and the exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
