Description

Technical Field

[0001] This utility model relates to the technical field of workpiece pressing, specifically a dual-station vertical tumbling platform. Background Technology

[0002] Existing dual-station tumbling platforms mainly utilize turntables and servo translation mechanisms. The turntable is a vertical shaft that rotates horizontally to complete the reciprocating rotation switching action between the two stations. When actually transporting products, this type of turntable can only transport relatively short products. Once the product length is long, the diameter of the turntable will increase with the increase in product length, which will lead to the need for a very large equipment that occupies a lot of space. Moreover, if the turntable is very large, the working cycle will be relatively slow when switching between dual-station operations, which will seriously affect the production progress. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a dual-station vertical tumbling platform, which enables long products to quickly and efficiently switch between dual stations, while the entire platform occupies relatively little space, thus reducing the equipment's manufacturing cost.

[0004] A dual-station vertical tumbling platform, characterized in that it comprises:

[0005] The drive shaft has protruding partitions at both ends of its radial diameter, and the protruding partitions extend along the length of the drive shaft.

[0006] Two sets of discs;

[0007] And two sets of long workstation support frames;

[0008] The transmission shaft is fixed to the center of each set of disks at both ends along its length and protrudes outward. The two sets of protruding partitions divide the two sets of disks into two evenly distributed semi-cylindrical areas. The two ends of each set of long workstation support frames are respectively installed in the corresponding semi-cylindrical areas by bearings. One end of the transmission shaft protrudes outward and is fixedly fitted with a first central tooth after corresponding to the disk. The two ends of one set of diameters of the first central tooth are respectively engaged with the second transmission teeth located on both sides. The outer sides of each set of second transmission teeth are also respectively engaged with the third transmission teeth. Each set of third transmission teeth is fixedly fitted to the corresponding protruding end of the corresponding long workstation support frame.

[0009] In the initial position, the upper surfaces of the two long workstation support frames are set flush and used to place products for transfer operations.

[0010] Its further features are:

[0011] The first central tooth, the two second transmission teeth, and the two third transmission teeth are arranged at intervals on the same straight line;

[0012] The outer periphery of the first central tooth and the two second transmission teeth is provided with a protective cover. A support frame is provided outside the protective cover. The corresponding end of the transmission shaft corresponding to the first central tooth is supported by the internal bearing of the support frame. The other end of the transmission shaft passes through the center of another disc and protrudes outward and is supported by a bearing on the other end of the placement frame. The support frame and the placement frame are set to correspond to the fixed machine base.

[0013] The protruding part at one end of the drive shaft is used to connect an external servo motor and a reduction mechanism. The servo motor drives the drive shaft to reliably rotate the first center tooth and can stop at any angle.

[0014] Two concave alignment points are provided at both ends of a diameter on the turntable of the non-gear ring on the outer periphery of the two third transmission teeth. An alignment monitoring mechanism is fixedly provided on the external fixed machine base corresponding to the stop position of the set work station. The alignment monitoring mechanism includes a fixed mounting bracket and an alignment cylinder. When the long work station support rotates to the set position, the piston end of the alignment cylinder is pushed out and inserted into the corresponding concave alignment point. It is used to reliably monitor whether the position of the long work station support is stable and reliable.

[0015] The first central gear, the two second transmission gears, and the two third transmission gears are all helical gears, which meet the requirements of high speed, high efficiency, high precision, and low noise operation of the Yuxing system.

[0016] With this invention, an external motor drives the entire transmission shaft to rotate, which in turn drives the two discs to rotate. During the rotation, the first central gear drives the second transmission gear, which in turn drives the third transmission gear, thus ensuring that the upper surface of the long workstation support frame is always horizontal. The disc rotates half a circle, causing the positions of the two long workstation support frames to be interchanged. Then the external motor flips, causing the disc to rotate half a circle to reset, causing the positions of the two long workstation support frames to be interchanged again. This allows for continuous operation of the product, enabling long products to be quickly and efficiently switched between two workstations. The entire platform occupies relatively little space, reducing the manufacturing cost of the equipment. Attached Figure Description

Detailed Implementation

[0025] A dual-station vertical tumbling platform, see Figures 1-5 It includes a drive shaft 10, two sets of discs 20, and two sets of long workstation support frames 30;

[0026] A convex partition plate 40 is provided at both ends of one diameter of the drive shaft 20, and the convex partition plate 40 extends along the length of the drive shaft 20.

[0027] The two ends of the drive shaft 10 along its length are fixed to the center of each set of discs 20 and protrude outwards. Two sets of protruding partitions 40 divide the two sets of discs into two evenly distributed semi-cylindrical areas. The two ends of the protruding partitions 40 along their length are fixed to the inner surfaces of the corresponding discs. The two ends of each set of long workstation support frames 30 are installed in the corresponding semi-cylindrical areas by bearings. One end of the drive shaft 10 protrudes outwards and is fixedly fitted with a first central tooth 1. The two ends of one set of diameters of the first central tooth 1 are respectively meshed with the second drive teeth 2 located on both sides. The outer side of each set of second drive teeth 2 is also meshed with a third drive tooth 3. Each set of third drive teeth 3 is fixedly fitted to the corresponding protruding end of the corresponding long workstation support frame 30.

[0028] In the initial position, the upper surfaces of the two long workstation support frames 30 are set flush with each other and used to place products for transfer operations.

[0029] In a specific embodiment, the first central tooth 1, two second transmission teeth 2, and two third transmission teeth 3 are arranged at intervals on the same straight line;

[0030] The outer periphery of the first central tooth 1 and the two second transmission teeth 2 is provided with a protective cover 60. The outer side of the protective cover 60 is provided with a support frame 70. In specific implementation, the corresponding end of the transmission shaft 10 corresponding to the first central tooth 1 is supported by the internal bearing of the support frame 70. The other end of the transmission shaft 10 passes through the center of another disc 20 and protrudes outward, and is supported by a bearing on the other end of the placement frame 80. The support frame 70 and the placement frame 80 are set to correspond to the fixed machine base.

[0031] In specific implementation, a servo motor 90 and a reduction mechanism 100 are provided on the periphery of the protective cover 60. The reduction mechanism 100 is connected to the corresponding end of the transmission shaft 10. The servo motor 90 drives the transmission shaft 10 to reliably rotate the first central tooth 1 and can stop at any angle.

[0032] Two concave alignment points 32 are provided at both ends of a diameter on the turntable 31 of the non-gear ring on the outer periphery of the two third transmission teeth 3. An alignment monitoring mechanism 110 is fixedly provided on the external fixed machine base corresponding to the stop position of the set work station. The alignment monitoring mechanism 110 includes a fixed mounting bracket 111 and an alignment cylinder 112. When the long work station support 30 rotates to the set position, the piston end of the alignment cylinder 112 is pushed out and inserted into the corresponding concave alignment point 32. It is used to reliably monitor whether the position of the long work station support 30 is stable and reliable.

[0033] In practice, the first central gear 1, the two second transmission gears 2, and the two third transmission gears 3 are all helical gears, which meet the requirements of high speed, high efficiency, high precision, and low noise operation.

[0034] In specific implementation, the long workstation support frame 30 is also equipped with electrical components. An arc-shaped drag chain mechanism 120 is provided on the outside of the non-servo motor arrangement end of the drive shaft 10. The corresponding bearing position of the long workstation support frame 30 corresponding to the arc-shaped drag chain mechanism 120 is a hollow position 301. The electrical line passes through the hollow position 301 and enters the long workstation support frame 30 for electrical connection. The arc-shaped drag chain mechanism 120 ensures that the electrical connection is stable and reliable.

[0035] A magnetic ring 50 is also provided at the end of the drive shaft 10 away from the servo motor. The magnetic ring 50 is used to accurately detect the rotation position.

[0036] Its working principle is as follows: The servo motor and reduction mechanism drive the entire transmission shaft to rotate, which in turn drives the two discs to rotate. During the rotation, the first central gear drives the second transmission gear and then the third transmission gear, so that the upper surface of the long workstation support frame is always horizontal. The disc rotates half a circle, so that the positions of the two long workstation support frames are interchanged. Then the external motor flips, so that the disc rotates half a circle to reset, so that the positions of the two long workstation support frames are interchanged again. This allows for continuous operation of the product. It enables long products to quickly and efficiently switch between two workstations, and the entire platform occupies relatively little space, reducing the manufacturing cost of the equipment.
