Technical Field

[0001] The utility model relates to the technical field of workpiece conveying equipment, in particular to a rotary transition rack. Background Art

[0002] The transition rack placed on the workshop visit passage not only needs to transfer workpieces, but also cannot block the passage for visitors.

[0003] If the traditional rack occupies the workshop visit passage, it can only occupy the visit passage even when no workpiece needs to be transferred, which affects the walking of workers. Or the rack on the visit passage is made detachable. When not needed, the rack on the visit passage is removed. When needed, it is reinstalled. This method not only wastes manpower and material resources, but also has safety risks during frequent hoisting and unloading. Content of the Utility Model

[0004] In order to solve the technical problem that the existing transition rack is troublesome to disassemble and assemble after occupying the visit passage, the utility model provides a rotary transition rack.

[0005] The technical solution of the utility model is realized through the following scheme: a rotary transition rack, including a passage, a first rack and a second rack. The first rack and the second rack are asymmetrically distributed on both sides of the passage. A support base is placed on the passage. An active rotary drive assembly and a driven rotary rack are detachably arranged on the support base. The active rotary drive assembly drives and meshes with the driven rotary rack;

[0006] A protective cover is detachably installed on the outer surface of the driven rotary rack. Detection devices are arranged on both the support base and the protective cover. The detection devices are communicatively connected to the active rotary drive assembly.

[0007] Through the above technical scheme, the power is effectively transmitted to the slewing bearing through the active rotary drive assembly, thereby driving the driven rotary rack to rotate. When no workpiece needs to be transferred, it can rotate 90 degrees and be placed in an idle position without occupying the visit passage, optimizing the layout of the workshop. The detection device ensures that the driven rotary rack stops braking when rotating to the maximum limit distance. The protective cover prevents foreign objects from falling and affecting the transmission of the device, ensuring the stability and safety of the rack during rotation.

[0008] Preferably, the driven rotary rack includes a rotary rack and a slewing bearing. The outer ring of the slewing bearing is detachably installed at the bottom of the rotary rack.

[0009] Preferably, a detection bracket is detachably mounted on the support base. The number of the detection brackets is two, and the two detection brackets are arranged at a right angle on the outer surface of the support base.

[0010] Preferably, the detection device includes a trigger and two detectors. The trigger is mounted outside the protective cover shell, and the two detectors are respectively mounted on the detection brackets. The trigger and the detectors are adapted to each other.

[0011] Through the above technical solutions, the protective cover shell effectively covers the key components of the running connection, prevents the intrusion of sundries from above, protects the internal structure and precision components of the equipment, and extends the service life of the equipment. The slewing bearing perfectly connects the support base, the active rotary drive assembly and the rotary table frame to ensure smooth and efficient power transmission. The detectors are mounted on the detection brackets, and the trigger is mounted outside the protective cover shell to achieve effective cooperation between the trigger and the detectors. When the trigger is activated, the detectors can quickly and accurately capture the state or parameter changes of the detection object, thereby improving the detection efficiency and accuracy.

[0014] Through the above technical solutions, the detachable setting of the device greatly simplifies the process of later maintenance and component replacement. The meshing connection not only improves the transmission efficiency, but also ensures the stability and reliability of the transmission.

[0015] In summary, the utility model has the following beneficial effects:

[0016] 1. The utility model effectively transmits power to the slewing bearing through the active rotary drive assembly, thereby driving the driven rotary table frame to rotate.

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0031] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification. The present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] Rotating transition rack, as Figures 1-8 shown, includes a channel 101, a first rack 102 and a second rack 103. The first rack 102 and the second rack 103 are asymmetrically distributed on both sides of the channel 101. A support base 1 is placed on the channel 101. A driving rotation drive assembly 2 and a driven rotation rack 3 are detachably provided on the support base 1. The driving rotation drive assembly 2 drives and meshes with the driven rotation rack 3. The first rack 102 is farther from the channel 101, and the second rack 103 is closer to the channel 101. Therefore, the driven rotation rack 3 is set to be one short and one long. The support base 1 is cylindrical. A support plate 4 is provided on the support base 1. The support plate 4 detachably installs the driven rotation rack 3 and supports and abuts against the driven rotation rack 3. A driving installation and fixing part 7 is provided on the support plate 4. The driving rotation drive assembly 2 is detachably installed on the driving installation and fixing part 7. The driving installation and fixing part 7 and the support plate 4 are of an integral structure. The support plate 4 is integrally circular and welded on the outer surface of the support base 1. A protective cover 5 is detachably installed on the outer surface of the driven rotation rack 3. Detection devices 6 are provided on both the support base 1 and the protective cover 5. The protective cover 5 is in the shape of a round cover. The protective cover 5 prevents foreign objects from falling between the driving gear 22 and the slewing bearing, affecting the rotation drive. The detection devices 6 on the support base 1 and the protective cover 5 are adapted to each other. The detection device 6 is communicatively connected to the driving rotation drive assembly 2 and automatically stops after rotating in place, reducing manual operation and realizing automatic control.

[0033] As Figure 7 and Figure 8 shown, the driving rotation drive assembly 2 drives the driven rotation rack 3 to rotate back and forth by 90 degrees, and can rotate automatically at any time. When it is not necessary to transfer workpieces, it can rotate 90 degrees and be placed in an idle position to save space. Compared with the traditional detachable rack, this rotating transition rack does not need to be frequently disassembled and assembled, greatly saving manpower and material resources, reducing the safety risks caused by disassembling and assembling the rack, improving the safety of workshop operations, realizing that it does not obstruct the passage 101 for walking when idle, and being able to efficiently transfer workpieces when working.

[0034] The driven rotary table 3 includes a rotary table 31 and a slewing bearing 32. The outer ring of the slewing bearing 32 is detachably installed at the bottom of the rotary table 31. The protective housing 5 is detachably installed on the outer surface of the rotary table 31. The protective housing 5 covers the support base 1, the active rotary drive assembly 2 and the slewing bearing. The inner ring of the slewing bearing is detachably installed on the support base 1. The slewing bearing 32 is meshed and connected with the active rotary drive assembly 2. The rotary table 31 is in a T shape. Due to the asymmetric distribution of the first table 102 and the second table 103, the two arms of the rotary table 31 are of different lengths. The protective housing 5 is installed on the surface through a plurality of bolts. The outer ring of the slewing bearing is assembled with the bottom of the rotary table 31 through a plurality of bolts, and the outer ring is provided with teeth that are adapted to be meshed with the driving gear 22, thereby being driven to rotate. The inner ring of the slewing bearing 32 is assembled on the support plate 4 of the support base 1 through a plurality of bolts to perform lifting and support. The rotary table 31 is made of steel structure. The device adopts a detachable installation design, making the assembly, maintenance and replacement of components of the table more convenient.

[0035] The support base 1 is detachably installed with two inspection brackets 8. The two inspection brackets 8 are arranged on the support base 1 at a right angle. The inspection device 6 includes a trigger 61 and two detectors 62. The trigger 61 is installed on the outer side of the protective housing 5. The two detectors 62 are respectively installed on the inspection brackets 8. The trigger 61 and the detectors 62 are adapted to each other. The inspection device 6 is preferably a proximity switch. The detector 62 is communicatively connected to the speed reducer 21. The inspection bracket 8 is in an L shape. One end of the inspection bracket 8 is close to the outer surface of the protective housing 5, and the other end is bolted to the support base 1. The detector 62 is installed on the inspection bracket 8 at the end close to the protective housing 5. Since the protective housing 5 is installed on the outer surface of the rotary table 31 and will rotate together with the rotary table 31, the trigger 61 will be driven to rotate. When the detector 62 is triggered, the speed reducer 21 is controlled to stop driving, completing the rotation. It ensures that when the rotary table 31 rotates to a specific position (limit position), the automatic trigger stop mechanism is activated, preventing equipment damage or personal injury caused by excessive rotation, and significantly improving the operation safety. The use of the proximity switch accurately judges the position of the rotary table 31 and controls the start and stop of the speed reducer 21, improving the automation degree of the production line.

[0036] The active rotary drive assembly 2 includes a speed reducer 21 and a driving gear 22. The speed reducer 21 is meshed and connected with the driven rotary table 3 through the driving gear 22. The speed reducer 21 is detachably installed on the drive installation fixing part 7. A gear gland is additionally installed at the assembly part of the driving gear 22 and the speed reducer 21, which not only prevents the risk of the gear falling off due to vibration or impact during high-speed rotation, but also enhances the structural strength of the entire transmission system. The speed reducer 21 drives the driving gear 22, thereby driving the slewing bearing meshed with it to rotate the rotary table 31.

[0037] Both the parts and the equipment adopt conventional models in the prior art, and the circuit communication connection adopts the conventional connection method in the prior art, which will not be elaborated here. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0038] Working principle: The staff starts the speed reducer 21, which drives the driving gear 22 to rotate, thereby driving the slewing bearing 32 meshed with the driving gear 22. The outer ring of the slewing bearing is stressed to drive the rotating table 31 to rotate;

[0039] When the rotating table 31 rotates, it drives the protective cover 5 installed on its outer surface. Since the trigger 61 is installed on the protective cover 5, when it rotates to the position of the detector 62, the detector 62 triggers the automatic stop of the speed reducer 21.

[0040] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification and equivalent change made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
