Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically to a photoelectric protection turret tilting device. Background Technology

[0002] In the field of machining, especially in the operation of turning over heavy components such as turrets, a turning device driven by a drive motor is often used. If such a device turns over abnormally due to a program error or control failure during operation, it is very easy to cause a violent collision with surrounding equipment or structures, resulting in serious mechanical damage and safety accidents.

[0003] Therefore, a safety protection device that can promptly trigger a stop action under abnormal conditions is needed. Traditional photoelectric protection switches are usually fixed in installation, and their trigger position is not adjustable, making it impossible to flexibly adapt to the protection height requirements under different working conditions. Furthermore, in emergency situations, it is difficult for personnel to quickly and accurately trigger the protection switch, resulting in certain limitations in use and safety risks. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a photoelectric protection turret tilting device, which solves the problem of emergency shutdown of traditional tilting turrets. By controlling the rotation of the drive motor through an infrared photoelectric switch, it is easy to shut down the drive motor in an emergency, thus improving the safety during tilting processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photoelectric protection turret tilting device, comprising a bracket, a drive motor, a transmission mechanism, and an infrared photoelectric protection switch. The drive motor is fixed to the bracket, and its output end is connected to the transmission mechanism. The drive motor includes a connecting plate fixedly connected to the side of the bracket. A support frame is fixed to the end of the connecting plate. A sliding plate is provided inside the support frame, and an infrared photoelectric protection switch is provided on the sliding plate. A sliding plate is also provided inside the support frame, and a C-shaped shield is fixed to the upper end of the sliding plate to block the trigger end of the infrared photoelectric protection switch.

[0006] Furthermore: an adjusting rod is provided at the top of the support frame, the adjusting rod is threadedly connected to the fixed plate, the top of the adjusting rod passes through the support frame and is fixed with a lever, rotating the lever can drive the fixed plate and the infrared photoelectric protection switch to move up and down together.

[0007] Furthermore: a screw is fixed to the lower end of the infrared photoelectric protection switch, and the screw passes through the fixing plate and is fixed by a fixing button.

[0008] Furthermore, a clearance groove is provided in the middle of the lower end of the skateboard.

[0009] Furthermore, a fixing tooth for limiting the position is fixed on the end face of the slide plate near the infrared photoelectric protection switch.

[0010] Furthermore, the signal output terminal of the infrared photoelectric protection switch is electrically connected to the PLC controller that controls the drive motor.

[0011] This invention provides an optoelectronic protection turret tilting device. Compared with the prior art, it has the following advantages:

[0012] This photoelectric protection turret tilting device features a height-adjustable infrared photoelectric protection switch design, allowing it to flexibly adapt to different working conditions and protection height requirements, making it highly versatile. The C-shaped shield and sliding trigger structure make emergency stop operations more intuitive, precise, and convenient, significantly shortening emergency response time. The entire device has a compact and reasonable structure, is easy to adjust, and can effectively trigger interlock protection in case of equipment malfunction, automatically stopping the drive motor to prevent mechanical collisions, ensuring high safety and reliability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5This utility model provides a technical solution: a photoelectric protection turret tilting device; specifically, it includes a drive motor 2, with a transmission mechanism 3 at the output end of the drive motor 2. The drive motor 2 drives the transmission mechanism 3 to rotate, thereby causing the material to tilt. A bracket 1 is fixed at the lower end of the drive motor 2, and the bracket 1 can be fixed on the workbench. This is existing public technology and will not be described in detail here. A connecting plate 4 is fixedly connected to the side of the bracket 1, and a support frame 5 is fixed at the upper end of the connecting plate 4. An infrared photoelectric protection switch 8 that can slide up and down is set inside the support frame 5. The core principle of the infrared photoelectric protection switch 8 is to use an infrared beam to form an invisible protective wall. When this wall is interrupted by an object, the device will trigger an emergency stop signal. This allows the tilting action to be stopped by connecting the infrared photoelectric switch and programming to the PLC. When the turret tilts abnormally, the drive motor 2 is automatically interlocked and shut down, thereby stopping the tilting action and preventing mechanical collision.

[0021] A fixing plate 10 is slidably installed inside the support frame 5 with upper and lower limits. A screw 9 is fixed to the lower end of the infrared photoelectric protection switch 8. The screw 9 passes through the fixing plate 10 and is threaded with a fixing button at the lower end of the fixing plate 10, so that the infrared photoelectric protection switch 8 is fixed to the end of the fixing plate 10. The fixing plate 10 is located inside the support frame 5 with one end limited and slidably moving up and down within the support frame 5. An adjusting rod 6 is installed on the support frame 5 and is threadedly connected to the fixing plate 10. The top end of the adjusting rod 6 passes through the support frame 5, and a lever 7 is fixed to the top end of the adjusting rod 6. The lever 7 drives the adjusting rod 6 to rotate, thereby adjusting the fixed plate 10 to move up and down inside the support frame 5, and thus adjusting the infrared photoelectric protection switch 8 to move up and down. The adjustment is made according to the actual height, so that it can be triggered in time during an emergency.

[0022] A sliding plate 11 that moves up and down is provided inside the fixed plate 10. A cover plate 14 is fixed at the upper end of the sliding plate 11. The cover plate 14 is C-shaped. When the infrared photoelectric protection switch 8 is triggered, the cover plate 14 can be pressed down directly. When pressed, the sliding plate 11 slides down, thereby driving the cover plate 14 to cover the trigger end of the infrared photoelectric protection switch 8. This operation is more precise and convenient.

[0023] A clearance groove 12 is provided in the middle of the lower end of the slide plate 11. A fixing tooth 13 is fixed on the end face of the slide plate 11 near the infrared photoelectric protection switch 8. The fixing tooth 13 can conveniently limit the position of the slide plate 11 when it slides down, and can be easily restored through the clearance groove 12.
