Description

Technical Field

[0001] This utility model relates to the technical field of automation mechanisms, specifically a 180-degree in-situ flipping mechanism. Background Technology

[0002] A 180-degree in-situ flipping mechanism typically consists of a support frame, a flipping frame, and a power mechanism. The flipping frame is mounted on the support frame via a pivot, and the power mechanism drives the flipping frame to rotate 180 degrees. This mechanism has a compact structure, enabling maximum range of motion within a limited space, and is widely used in packaging equipment, automated production lines, and other applications, improving production efficiency.

[0003] For example, the existing flipping mechanism disclosed in CN107444888B specifically includes a guide support assembly, a flipping assembly, and a drive assembly. The guide support assembly includes two spaced-apart support seats and sliding supports that slide along the corresponding support seats in a preset direction. The flipping assembly includes two flipping arms and clamping parts disposed on the flipping arms. One end of the flipping arm is hinged between the two support seats, and the clamping parts cooperate with the flipping arms to form a fixed position for fixing the element to be flipped. The drive assembly includes a drive member and a first connecting rod. One end of the first connecting rod is hinged to the mounting surface, and the other end is hinged to the flipping arm. The drive member includes a fixed end and a telescopic end. The fixed end of the drive member is hinged to the sliding support, and the telescopic end of the drive member is hinged to the flipping arm. The above-mentioned flipping mechanism has a high degree of automation, is easy to operate, and reduces labor intensity.

[0004] Due to the varying lengths of workpieces, existing 180-degree in-situ flipping mechanisms are unsuitable for workpieces of different lengths. Incompatible flipping mechanisms may require frequent replacement or adjustment, leading to production interruptions and reduced overall production efficiency. To meet the needs of workpieces of different lengths, it may be necessary to purchase flipping mechanisms of various specifications, which undoubtedly increases the company's equipment purchase and maintenance costs. Therefore, we propose the 180-degree in-situ flipping mechanism. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mechanism for 180-degree in-situ flipping.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model relates to a 180-degree in-situ flipping mechanism, which includes a base, a stand fixedly mounted on the base, an installation mechanism on the stand, a frame on one side of the stand, the frame being connected to the installation mechanism, the installation mechanism being used to install the frame on the stand, and the installation mechanism being able to drive the frame to flip.

[0008] The frame contains two spaced-apart movable seats, and two spaced-apart guide rods are fixedly installed within the frame, passing through both ends of the movable seats. A bidirectional lead screw is rotatably installed within the frame, passing through the movable seats and threadedly connected to them. A first motor is fixedly installed outside the frame, and the output shaft of the first motor is fixedly connected to the bidirectional lead screw. A U-shaped plate is fixedly installed at each end of the movable seats, and a pressure plate is provided within the U-shaped plate. Guide frames are fixedly installed at both ends of the pressure plate, passing through the U-shaped plates. A screw is rotatably installed on the pressure plate, passing through the U-shaped plates and threadedly connected to them.

[0009] As a preferred embodiment of this utility model, a handle is fixedly installed at the end of the screw.

[0010] As a preferred embodiment of this utility model, anti-slip pads are fixedly connected to the opposite sides of the pressure plate and the U-shaped plate.

[0011] As a preferred technical solution of this utility model, the base is provided with a plurality of equally spaced threaded mounting holes.

[0012] As a preferred embodiment of this utility model, the mounting mechanism includes a spline sleeve, which is rotatably mounted on the stand. A spline shaft is inserted into the spline sleeve, and the spline shaft is splinedly engaged with the spline sleeve. One end of the spline shaft is fixedly connected to the frame, and a connecting plate is rotatably mounted on the spline shaft. The spline shaft passes through the connecting plate. Two spaced-apart electric push rods are fixedly mounted on the stand, and the output ends of the electric push rods are fixedly connected to the connecting plate.

[0013] As a preferred embodiment of this utility model, a second motor is fixedly installed on one side of the stand, and the output shaft of the second motor is fixedly connected to the spline sleeve.

[0014] As a preferred embodiment of this utility model, a dust cover is installed on the outside of the second motor.

[0015] The beneficial effects of this utility model are:

[0016] This 180-degree in-situ flipping mechanism fixes the workpiece at both ends within U-shaped plates on both sides. A second motor drives the spline sleeve to rotate, causing the spline sleeve, spline shaft, and frame to rotate synchronously. The movable seat within the frame also rotates synchronously, as do the movable seat and the U-shaped plates. This allows the workpiece to rotate around the spline shaft and flip 180 degrees or rotate to other angles. When the second motor stops, it self-locks, maintaining the workpiece at a fixed angle.

[0017] The first motor drives the bidirectional lead screw to rotate, which in turn drives the two movable seats to move synchronously in opposite directions, thereby adjusting the distance between the two movable seats. The U-shaped plates of the movable seats move synchronously, thereby adjusting the distance between the two U-shaped plates. The distance between the two pressure plates is adjustable, which can be used for workpieces of different lengths and can fix workpieces of different lengths.

[0018] The connecting plate is moved by an electric push rod, which in turn moves the spline shaft synchronously. The spline shaft then moves the U-shaped plate back and forth, which in turn moves the workpiece on the mechanism back and forth. This allows for fine-tuning of the workpiece's position, ensuring that the workpiece can accurately reach the predetermined position after being flipped, thus meeting different processing requirements.

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the 180-degree in-situ flipping mechanism of this utility model includes a base 1, a stand 2 fixedly mounted on the base 1, an installation mechanism on the stand 2, a frame 3 on one side of the stand 2, and the frame 3 connected to the installation mechanism. The installation mechanism is used to install the frame 3 on the stand 2 and can drive the frame 3 to flip. Two spaced-apart movable seats 4 are provided inside the frame 3, and two spaced-apart guide rods 5 are fixedly mounted inside the frame 3, passing through both ends of the movable seats 4. A bidirectional lead screw 6 is rotatably mounted inside the frame 3, passing through the movable seats 4 and threadedly connected to them. A first motor 7 is fixedly mounted outside the frame 3, and the output shaft of the first motor 7 is fixedly connected to the bidirectional lead screw 6. U-shaped plates 8 are fixedly mounted at the ends of the movable seats 4, and pressure plates 9 are provided inside the U-shaped plates 8. Guide frames 10 are fixedly mounted at both ends of the pressure plates 9, passing through the U-shaped plates 8. A screw 11 is rotatably mounted on the pressure plates 9, passing through the U-shaped plates 8 and threadedly connected to them. A handle is fixedly installed at the end of the screw 11 for easy rotation. Anti-slip pads are fixedly connected to the opposite sides of the pressure plate 9 and the U-shaped plate 8, so that the workpiece is fixed between the pressure plate 9 and the U-shaped plate 8 and does not slip easily.

[0028] The machine base 1 has multiple equally spaced threaded mounting holes, allowing it to be installed on an external automated production line. The mounting mechanism includes a spline sleeve 12, rotatably mounted on a stand 2. A spline shaft 13 is inserted into the spline sleeve 12, engaging with it via splines. One end of the spline shaft 13 is fixedly connected to a frame 3. A connecting plate 14 is rotatably mounted on the spline shaft 13, passing through it. Two spaced-apart electric push rods 15 are fixedly mounted on the stand 2, their output ends fixedly connected to the connecting plate 14. A second motor 16 is fixedly mounted on one side of the stand 2, its output shaft fixedly connected to the spline sleeve 12. A dust cover is installed around the second motor 16. The electric push rod 15 drives the connecting plate 14 to move, the connecting plate 14 drives the spline shaft 13 to move synchronously, and the spline shaft 13 drives the U-shaped plate 8 to move back and forth, which can drive the workpiece on the mechanism to move back and forth, thereby fine-tuning the position of the workpiece to adapt to different processing requirements.

[0029] Working principle:

[0030] By placing the end of the workpiece between the pressure plate 9 and the U-shaped plate 8, as can be referred to Figure 1As shown, rotating the screw 11 moves the pressure plate 9, causing it to press the workpiece beneath it, fixing both ends of the workpiece within the U-shaped plates 8 on both sides. The second motor 16 drives the spline sleeve 12 to rotate, causing the spline sleeve 12, spline shaft 13, and frame 3 to rotate synchronously. The movable seat 4 within the frame 3 also rotates synchronously, as do the movable seat 4 and the U-shaped plates 8. This allows the workpiece to rotate around the spline shaft 13 and to perform a 180-degree flip or rotate to other angles. When the second motor 16 stops, it self-locks, maintaining the workpiece's angle in a fixed state.

[0031] When the length of the workpiece changes, the first motor 7 drives the bidirectional lead screw 6 to rotate, which can drive the two movable seats 4 to move synchronously and in opposite directions, thereby adjusting the distance between the two movable seats 4. The U-shaped plates 8 of the movable seats 4 move synchronously, thereby adjusting the distance between the two U-shaped plates 8. The distance between the two pressure plates 9 is adjustable, which can be used for workpieces of different lengths and can fix workpieces of different lengths.

[0032] The electric push rod 15 drives the connecting plate 14 to move, which in turn drives the splined shaft 13 to move synchronously. The splined shaft 13 then drives the U-shaped plate 8 to move back and forth, thus moving the workpiece on the mechanism back and forth. This allows for fine-tuning of the workpiece's position to adapt to different processing requirements. The fine-tuning ensures that the workpiece accurately reaches the predetermined position after flipping, meeting various processing needs.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
