Description

Technical Field

[0001] The invention relates to the technical field of railway wheel processing, and in particular to a turning device for railway wheel processing and manufacturing. Background Art

[0002] In the processing and manufacturing process of train wheels, the flipping device is an important equipment, and its function is to flip the train wheels to different angles to meet the needs of processing operations on various surfaces. However, existing train wheel flipping devices may cause the train wheels to fall off. For example, during the flipping process, the train wheels may fall off due to impact force and vibration generated by operations such as drilling and cutting.

[0003] The falling off of train wheels will not only cause damage to the processed parts, but also pose a serious threat to the safety of operators, and will also affect production efficiency.

[0004] In summary, we have proposed a flipping device for anti-falling railway wheel processing and manufacturing to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a turning device for processing and manufacturing railway wheels. The double clamping method significantly enhances the clamping stability of the railway wheels by superimposing the clamping forces of two stages.

[0006] To achieve the above object, the present invention proposes the following scheme: A turning device for processing and manufacturing train wheels comprises a base, the upper end of the base is fixedly connected to a mounting frame, a lifting frame is fixedly connected to the side surface of the mounting frame, a lifting frame is provided on the side surface of the lifting frame and a lifting turning mechanism is provided, a front end of the turning mechanism is rotatably connected to a clamping mechanism, a rubber pad is provided on the upper end surface of the base, the rubber pad fully covers the area between the two mounting frames, a placement circular plate for placing the train wheel is provided at the center of the upper surface of the rubber pad, and an early warning mechanism is installed on one side of the upper surface of the base; A motor is provided inside the flip mechanism, the front end of which is rotatably connected to a rotating disk, the output end of the motor is transmission-connected to the rotating disk, the lower end of the outer surface of the rotating disk is fixedly connected to a support plate, the upper surface of the support plate is fixedly mounted with a first hydraulic cylinder, and a movable clamping mechanism is provided; Side clamps are integrally arranged on both sides of the clamping mechanism. The clamping mechanism and the side clamps are used together to clamp the train wheels in the first stage. A second hydraulic cylinder is arranged inside the clamping mechanism. A clamping plate is connected to the output end of the second hydraulic cylinder. The clamping plate is used to clamp the train wheels in the second stage. A pressure sensor is arranged inside the side clamp for detecting pressure.

[0007] A control panel is installed on one side of the upper surface of the base, and an early warning mechanism installed on the other side includes a mounting rod and an early warning light, and the early warning light is fixedly connected to the mounting rod.

[0008] A lifting motor is installed on the upper surface of the lifting frame, a lifting groove is opened on the side surface of the lifting frame, a threaded rod is arranged inside the lifting groove, the output end of the lifting motor passes through the lifting groove and is transmission-connected with the threaded rod, a lifting block is threadedly connected to the outer surface of the threaded rod, and the side surface of the lifting block is fixedly connected to the flipping mechanism.

[0009] A sensing groove is provided on the upper surface of the side clamp, a pressure sensor is installed on the inner wall of the sensing groove, and a first flexible pad is fixedly connected to the outer surface of the side clamp.

[0010] A hydraulic groove is provided on the upper surface of the clamping mechanism, the second hydraulic cylinder is located inside the hydraulic groove, the output end of the second hydraulic cylinder passes through the hydraulic groove and is fixedly connected to the clamping plate, and a second flexible pad is fixedly connected to the front surface of the clamping plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects: (1) The invention provides a turning device for processing and manufacturing train wheels. The double clamping method significantly enhances the clamping stability of the train wheels by superimposing the clamping forces of two stages. In particular, during the turning process, the train wheels need to withstand large centrifugal forces and vibrations. The double clamping can effectively prevent the train wheels from being displaced or falling off due to these external forces, thereby ensuring the continuity and safety of the processing process.

[0012] (2) In a turning device for processing and manufacturing train wheels of the present invention, a pressure sensor monitors the pressure of the clamping mechanism in real time. When the vibration generated by the milling cutter causes the clamping force to decrease, the pressure sensor can quickly detect the pressure abnormality and transmit the information to the control panel. After receiving the signal, the control panel immediately starts the second hydraulic cylinder to push the clamping plate for secondary clamping, quickly increasing the pressure to ensure that the clamping effect is always in the best state.

[0013] (3) The present invention provides a turning device for processing and manufacturing railway wheels. The outer surface of the side clamp is fixedly connected to a first flexible pad, and the front surface of the clamp is fixedly connected to a second flexible pad. These flexible pads are made of rubber with a Shore hardness of 65 and a thickness of 6 mm. In the process of clamping the railway wheel, the flexible pad can play a buffering role, reduce the hard collision and friction between the railway wheel and the clamp, prevent the surface of the clamp from being worn due to long-term stress, extend the service life of the clamp, and reduce the maintenance and replacement frequency of the clamp.

[0014] (4) The present invention provides a turning device for processing and manufacturing train wheels. The rubber pad disposed on the upper surface of the base fully covers the area between the two mounting frames, and a circular plate for placing the train wheels is disposed at the center. When the train wheels accidentally fall off during processing, the rubber pads can act as a buffer, effectively preventing the train wheels from being damaged or damaging the equipment, thereby reducing the equipment maintenance cost and the risk of train wheels being scrapped, and ensuring the safety of the production environment.

A pressure sensor 512 is provided inside the side clamp 51 for detecting pressure. When in use, the train wheel to be processed is placed on the upper end of the placement circular plate 121, and then the lifting frame 31 is driven to drive the clamping mechanism 5 to descend. The train wheel can be clamped by the clamping mechanism 5, and then the lifting frame 31 drives the clamping mechanism 5 to rise to the processing height. The rotation is achieved by the flipping mechanism 4, and the flipping processing can be completed. The rubber pad 12 is specifically made of a rubber material, which fully covers the area between the two lifting frames 31. Certain protective measures can be taken when the train wheel falls off to prevent the train wheel from being damaged or smashing the equipment.

When in use, the milling cutter continuously processes the train wheel, which may cause the clamping force to become lower due to vibration. When the pressure sensor 512 predicts that the clamping pressure is lower than a certain value, it quickly transmits the information to the control panel 11. After receiving the signal, the control panel 11 quickly responds to transmit a start signal to the second hydraulic cylinder 521. The second hydraulic cylinder 521 starts to push the clamping plate 53, and the clamping plate 53 is pushed forward to achieve secondary clamping, which immediately increases the pressure and improves the clamping effect, thereby reducing the risk of the train wheel falling off.
