[0002] Railway vehicles need regular maintenance, including the coupler. One of the coupler parts is the hook tail frame. After the hook tail frame is disassembled, it needs to be sandblasted, rust-removed, and flaw-detected. After that, it needs to be assembled again. This is done in the form of an assembly line. However, the hook tail frame usually has multiple specifications. When sandblasting, rust-removing, and flaw-detecting, one maintenance line is used, and when assembling, it is necessary to assemble according to the model. Therefore, the hook tail frames of multiple specifications on one line need to be transferred to different installation lines according to the specifications. At present, there is no equipment in the prior art that can efficiently and reasonably solve the above problems. Utility Model Content

[0003] The problem solved by the utility model is that there is no device in the prior art that can efficiently and reasonably solve the problem of transferring hook tail frames of various specifications on one line to different installation lines according to specifications, and provides an intelligent caching and feeding mechanism for hook tail frames of multiple specifications.

[0004] The utility model is realized by the following technical scheme, a multi-specification hook tail frame intelligent buffer feeding mechanism, comprising:

[0005] A transfer mechanism, wherein the transfer mechanism comprises a portal frame, a horizontal moving mechanism, a vertical moving mechanism, a rotating mechanism, and an electromagnetic chuck, wherein the horizontal moving mechanism is mounted on the portal frame, the vertical moving mechanism is mounted on the movable end of the horizontal moving mechanism, the rotating mechanism is mounted on the movable end of the vertical moving mechanism, and the electromagnetic chuck is mounted on the movable end of the vertical moving mechanism;

[0006] The inspection and conveying mechanism is used to transport hook tail frames of various specifications, including at least a first hook tail frame and a second hook tail frame;

[0007] A first assembly conveying mechanism, used for conveying a first hook tail frame;

[0008] A second assembly conveying mechanism is used to convey a second hook tail frame;

[0009] The cache mechanism includes a bottom guide rail, a mobile platform, and a platform driving mechanism. The mobile platform is slidably arranged on the bottom guide rail and is driven to move by the platform driving mechanism. At least a first placement platform and a second placement platform are arranged on the mobile platform. The first placement platform and the second placement platform are both parallel to the horizontal moving mechanism, and the moving direction of the mobile platform is perpendicular to the moving direction of the horizontal moving mechanism.

[0010] An industrial camera, which is fixedly installed next to the inspection and conveying mechanism and can identify the position and model of the hook tail frame on the inspection and conveying mechanism;

[0011] One end of the inspection and conveying mechanism, the first assembly and conveying mechanism, and the second assembly and conveying mechanism are all located below the working area of ​​the transfer mechanism.

[0012] Furthermore, the first assembly conveying mechanism and the second assembly conveying mechanism are both step-by-step conveying mechanisms.

[0013] Furthermore, a first connecting plate is installed at the movable end of the rotating mechanism, the electromagnetic suction cup is installed on a second connecting plate, the first connecting plate and the second connecting plate are slidingly connected through a plurality of guide rods, nuts for limiting are installed at both ends of the guide rods, and a spring is provided on the guide rod outer sleeve.

[0014] Furthermore, a weighing sensor is arranged between the movable end of the rotating mechanism and the first connecting plate.

[0015] Furthermore, a balancing cylinder is installed at the movable end of the horizontal moving mechanism, the balancing cylinder is vertically arranged, and the piston rod of the balancing cylinder is connected to the movable end of the vertical moving mechanism.

[0016] The beneficial effects of the utility model are:

[0017] 1. The maintenance conveying mechanism of the utility model conveys the first hook tail frame and the second hook tail frame, and the industrial camera performs visual recognition to determine the model of the hook tail frame. Then the transfer mechanism transfers the first hook tail frame and the second hook tail frame to the first assembly conveying mechanism, the second assembly conveying mechanism or the cache mechanism through magnetic suction, lifting, rotation, and walking. The first conveying mechanism and the second assembly conveying mechanism feedback whether there is a placement position. If there is a placement position, the transfer mechanism directly transfers the first hook tail frame and the second hook tail frame to the first assembly conveying mechanism and the second assembly conveying mechanism. If there is no placement position, it is placed on the cache mechanism. The first placement table and the second placement table of the cache mechanism are respectively used to place the first hook tail frame and the second hook tail, and when placing, they start to place close to the corresponding assembly conveying mechanism. After the assembly conveying mechanism conveys forward, when there is a vacancy, the transfer mechanism transfers the hook tail frame on the cache mechanism to the corresponding assembly conveying mechanism with a vacancy. Due to the existence of the cache mechanism, the unloading of the maintenance conveying mechanism is not affected by the assembly speed, which improves the smoothness of the operation of the maintenance line.

[0018] 2. The utility model can adaptably increase the number of placement tables and assembly conveyor lines according to the specifications and quantity of the hook tail frames, and can meet the requirements of various working conditions.

[0019] 3. The electromagnetic chuck and the rotating mechanism of the utility model are elastically connected so as to be able to slide up and down. After the electromagnetic chuck and the hook tail frame come into contact, the spring can continue to be compressed to meet the needs of hook tail frames of different heights and reduce the impact force of the contact.

[0020] 4. A weighing sensor is arranged between the movable end of the rotating mechanism of the utility model and the first connecting plate. The weight of each hook tail frame is different. Weighing is used to assist in detecting the model and cooperate with the industrial camera to improve the detection accuracy and avoid errors.

[0021] 5. A balancing cylinder is installed at the movable end of the horizontal moving mechanism of the utility model. The balancing cylinder is vertically arranged, and the piston rod of the balancing cylinder is connected to the movable end of the vertical moving mechanism. The balancing cylinder balances the gravity of the vertical moving mechanism, the rotating mechanism, and the electromagnetic suction cup, reduces the workload of the motor of the vertical moving mechanism, and can increase the lifting speed.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The embodiment aims to solve the problem of hook tail frame placement management, divert various specifications of hook tail frames on the maintenance line to assembly lines of their respective specifications, and realize automatic flow of hook tail frames between the maintenance line, assembly line and storage area.

[0034] like Figure 1-3 As shown, a multi-specification hook tail frame intelligent cache feeding mechanism includes a transfer mechanism 1, a maintenance conveying mechanism 2, a first assembly conveying mechanism 3, a second assembly conveying mechanism 4, a cache mechanism 5, and an industrial camera 6.

[0035] The transfer mechanism 1 includes a portal frame 101, a horizontal moving mechanism 102, a vertical moving mechanism 103, a rotating mechanism 104, and an electromagnetic suction cup 105. Specifically, the horizontal moving mechanism 102 is installed on the portal frame 101. The portal frame 101 adopts a cantilever track, a power rack is installed, and a gear drive is adopted. The counter and the inductive sensor are used to locate the horizontal position. The vertical moving mechanism 103 is installed at the movable end of the horizontal moving mechanism 102. The vertical moving mechanism 103 is composed of a gear rack driven by a lifting motor, with a stroke of 820mm, and a gear drive is adopted. The counter and the inductive sensor are used to locate the vertical position. The rotating mechanism 104 is installed at the movable end of the vertical moving mechanism 103. The rotating mechanism 104 adopts a rotating motor to control the rotation of the electromagnetic suction cup 105. The electromagnetic suction cup 105 is installed at the movable end of the vertical moving mechanism 103, with a maximum suction force of not less than 1.5 tons, and has a power-off magnetic function, a rotation speed of 6r / min, and a speed-controlled variable frequency; the transfer mechanism 1 has magnetic suction, lifting, rotation, walking, and positioning functions.

[0036] The maintenance conveying mechanism 2 adopts a plate chain conveyor, which is used to transport hook tail frames of various specifications, including at least a first hook tail frame and a second hook tail frame; the maintenance conveying mechanism 2 is parallel to the portal frame 101, and the end of the maintenance conveying mechanism 2 is located below the right end of the portal frame 101.

[0037] The first assembly conveying mechanism 3 is used to convey the first hook tail frame. The first assembly conveying mechanism 3 is perpendicular to the portal frame 101 , and the end of the first assembly conveying mechanism 3 is located below the portal frame 101 .

[0038] The second assembly conveying mechanism 4 is used to convey the second hook tail frame. The second assembly conveying mechanism 4 and the first assembly conveying mechanism 3 are arranged in parallel. The end of the second assembly conveying mechanism 4 is located below the portal frame 101 .

[0039] The cache mechanism 5 includes a bottom rail 501, a mobile platform 502, and a platform driving mechanism 503. The mobile platform 502 is slidably arranged on the bottom rail 501. The mobile platform 502 is about 3m long and 2.2m wide, and is welded from square steel. The platform driving mechanism 503 uses an oil cylinder, which is arranged below the mobile platform 502. At least a first placement platform 504 and a second placement platform 505 are arranged on the mobile platform 502; the first placement platform 504 and the second placement platform 505 are parallel to the horizontal moving mechanism 102, and the moving direction of the mobile platform 502 is perpendicular to the moving direction of the horizontal moving mechanism 102. Driven by the oil cylinder, the first placement platform 504 and the second placement platform 505 move to the right below the transfer mechanism 1 in turn according to demand.

[0040] The industrial camera 6 is fixedly installed next to the maintenance conveying mechanism 2, and can identify the position and model of the hook tail frame on the maintenance conveying mechanism 2 through visual learning.

[0041] When the present embodiment is working, the inspection conveying mechanism 2 conveys the first hook tail frame and the second hook tail frame, the industrial camera 6 performs visual recognition to determine the model of the hook tail frame, and then the transfer mechanism 1 transfers the first hook tail frame and the second hook tail frame to the first assembly conveying mechanism 3, the second assembly conveying mechanism 4 or the cache mechanism 5 through magnetic attraction, lifting, rotation and walking actions. The first conveying mechanism and the second assembly conveying mechanism 4 feedback a signal whether there is a placement position. If there is a placement position, the transfer mechanism 1 directly transfers the first hook tail frame and the second hook tail frame to the first assembly conveying mechanism 3 and the second assembly conveying mechanism 4. If there is no placement position, they are placed on the cache mechanism 5. The first placement table 504 and the second placement table 505 of the cache mechanism 5 are respectively used for placing the first hook tail frame and the second hook tail, and when placing, they start to place close to the corresponding assembly conveying mechanism, such as Figure 3 As shown, the first hook tail frame on the first placement table 504 is placed from right to left, and the second hook tail frame on the second placement table 505 is placed from left to right. After the assembly conveying mechanism is conveyed forward, when a vacant position appears, the transfer mechanism 1 transfers the hook tail frame on the buffer mechanism 5 to the corresponding assembly conveying mechanism with a vacant position. Due to the existence of the buffer mechanism 5, the unloading of the maintenance conveying mechanism 2 is not affected by the assembly speed, which improves the smoothness of the operation of the maintenance line.

[0042] This embodiment is applicable to hook tail frames of two specifications. If there are three types of hook tail frames, a third assembly conveyor line is set, and a third placement table is set on the buffer mechanism 5. If there are more types of hook tail frames, then the same is true. The utility model can meet the working requirements.

[0043] In practical applications, the first assembly conveying mechanism 3 and the second assembly conveying mechanism 4 are both step-by-step conveying mechanisms. The oil cylinder drives the platform to move, and a hook that can be flipped in one direction is arranged on the platform. When the oil cylinder is actuated once, the movable hook tail frame moves forward one step, and a vacant position appears during the operation, which can remind the transfer mechanism 1 to move the hook tail frame to the assembly conveying line.

[0044] In practical applications, the movable end of the rotating mechanism 104 is installed with a first connecting plate 106, and the electromagnetic suction cup 105 is installed on a second connecting plate 107. The first connecting plate 106 and the second connecting plate 107 are slidably connected through a plurality of guide rods 108, and nuts for limiting are installed at both ends of the guide rods 108. The outer sleeve of the guide rods 108 is provided with a spring 109. Therefore, the electromagnetic suction cup 105 and the rotating mechanism 104 are elastically connected to slide up and down, and the spring 109 can continue to be compressed after the electromagnetic suction cup 105 contacts the hook tail frame, so as to meet the hook tail frames of different heights and reduce the impact force of the contact.

[0045] In actual applications, a weighing sensor (not shown in the figure) is arranged between the movable end of the rotating mechanism 104 and the first connecting plate 106. The weight of each hook tail frame is different. Weighing is used to assist in detecting the model and cooperate with the industrial camera 6 to improve the detection accuracy and avoid errors.

[0046] In actual application, a balancing cylinder 110 is installed at the movable end of the horizontal moving mechanism 102. The balancing cylinder 110 is vertically arranged, and the piston rod of the balancing cylinder 110 is connected to the movable end of the vertical moving mechanism 103. The balancing cylinder 110 balances the gravity of the vertical moving mechanism 103, the rotating mechanism 104, and the electromagnetic suction cup 105, reduces the workload of the motor of the vertical moving mechanism 103, and can increase the lifting speed.

[0047] In summary, due to the presence of the buffer mechanism 5, the material unloading of the maintenance conveying mechanism 2 of the multi-specification hook tail frame intelligent buffer feeding mechanism described in the utility model is not affected by the assembly speed, thereby improving the smoothness of the operation of the maintenance line.

[0048] The above shows and describes the basic principles, main features and advantages of the utility model. The technicians in this industry should understand that the above implementation is only to illustrate the technical concept and characteristics of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it, and it cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
