[0028] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0029] A needle bed base flipping fixture includes:

[0030] A base plate 1 is provided, a bearing plate 2 is provided directly above the base plate 1, a fixing plate 7 is provided directly above the bearing plate 2, a needle bed base body 3 is provided directly above the fixing plate 7, a fixing column 14 is fixedly installed at the top of the base plate 1 and at the four corners, the four fixing columns 14 penetrate the bearing plate 2 and are fixed to the bottom of the fixing plate 7, an electric push rod 13 is provided at the top of the base plate 1 and between the four fixing columns 14, the output end of the electric push rod 13 is fixed to the top of the bearing plate 2;

[0031] Four cylinders 11 are fixedly installed at the four corners of the top of the fixed plate 7. Rubber pads 10 are fixedly installed on the top of each of the four cylinders 11. The tops of the four rubber pads 10 are in contact with the bottom of the needle bed base body 3. The top of the bearing plate 12 is provided with a sliding groove 15.

[0032] Two side plates 9 are set in the slide groove 15. The two side plates 9 are located on both sides of the needle bed base body 3 and the fixing plate 7, respectively. Clamps 8 are set on the side of the two side plates 9 that are close to each other. The two clamps 8 are located on both sides of the needle bed base body 3, respectively. A second bearing plate 5 is fixedly installed on one side of one of the side plates 9. A second motor 6 is fixedly installed on the top of the second bearing plate 5. The output of the second motor 6 passes through one of the side plates 9 and is fixed to one of the clamps 8.

[0033] The power assembly is located on the support plate 2 and is used to drive the two side plates 9 to move closer or further apart. Through the cooperation of the base plate 1, support plate 2, needle bed base body 3, support plate 5, motor 6, fixing plate 7, clamp 8, side plate 9, rubber pad 10, cylinder 11, electric push rod 13, and fixing column 14, the overall device is a simple-to-operate, highly efficient, and easy-to-adjust needle bed base position with a simple structure and low maintenance cost flipping fixture. It not only improves work efficiency and reduces maintenance costs, but also enhances practicality and reliability, bringing great convenience to the use and maintenance of the needle bed base.

[0034] In this embodiment, the power assembly includes:

[0035] Motor 4 is located on top of the support plate 2 and on one side of the two side plates 9. A bidirectional threaded rod 12 is provided on the output shaft of motor 4. One end of the bidirectional threaded rod 12 passes through the two side plates 9. When motor 4 in the power assembly is started, its output shaft drives the bidirectional threaded rod 12 to rotate. Since the two side plates 9 are threadedly connected to the bidirectional threaded rod 12 and the side plates 9 are located in the slide groove 15 and are slidably connected to the slide groove 15, the rotation of the bidirectional threaded rod 12 causes the two side plates 9 to move closer to each other along the slide groove 15. The clamps 8 on the side plates 9 then move closer to the needle bed base body 3. Since the clamps 8 are adapted to the needle bed base body 3, they can finally firmly clamp the needle bed base body 3 from both sides, providing a stable clamp for flipping.

[0036] In this embodiment, the motor 4 is tightly welded to the bearing plate 2, and the side plate 9 is threadedly connected to the bidirectional threaded rod 12, ensuring the structural stability of the motor 4 and the bearing plate 2, and ensuring that under the action of the thread, the rotating bidirectional threaded rod 12 can drive the two side plates 9 to move closer or further apart.

[0037] In this embodiment, the bearing plate 2 is slidably connected to the fixed column 14, and the fixed column 14 is tightly welded to the fixed plate 7, ensuring that the bearing plate 2 can slide normally on the fixed column 14 and ensuring the structural stability of the fixed column 14 and the fixed plate 7.

[0038] In this embodiment, the electric push rod 13 is tightly welded to the support plate 2, and the side plate 9 is slidably connected to the slide groove 15, ensuring the structural stability of the electric push rod 13 and the support plate 2, and ensuring that the side plate 9 can slide normally in the slide groove 15.

[0039] In this embodiment, the side plate 9 is rotatably connected to the clamp 8, and the clamp 8 is adapted to the needle bed base body 3, ensuring that the clamp 8 can rotate normally on the side plate 9 and that the clamp 8 can clamp and fix the needle bed base body 3.

[0040] In this embodiment, the output shaft of motor 2 6 is tightly welded to the fixture 8 to ensure the structural stability of the output shaft of motor 2 6 and the fixture 8.

[0041] In this embodiment, the surface of the rubber pad 10 is provided with anti-slip texture to ensure that the surface of the rubber pad 10 has a large friction force.

[0042] In this embodiment, the needle bed base flipping fixture is used with the base plate 1 as a stable base. Four fixing columns 14 are fixed to the four corners of the top of the base plate 1, pass through the bearing plate 2, and are tightly welded to the bottom of the fixing plate 7 to form an overall frame. The needle bed base body 3 is placed stably on the four rubber pads 10 on the top of the fixing plate 7. The rubber pads 10 are connected to the fixing plate 7 through the cylinder 11. The anti-slip texture on its surface can increase the friction and prevent the needle bed base body 3 from sliding when initially placed. At this time, the electric push rod 13 is in the retracted state, the bearing plate 2 is located at a lower position above the base plate 1, and the two side plates 9 and the clamps 8 are in the open state, away from the needle bed base body 3.

[0043] When it is necessary to flip the needle bed base body 3, first activate the electric push rod 13 on the base plate 1. Since the output end of the electric push rod 13 is fixed to the top of the support plate 2 and the support plate 2 is slidably connected to the fixed column 14, when the electric push rod 13 extends, it will push the support plate 2 to slide upward along the fixed column 14. The side plate 9, clamp 8 and other components on the support plate 2 will move upward accordingly until the clamp 8 and both sides of the needle bed base body 3 are at the same horizontal height, meeting the position requirements for clamping operation. Then, the electric push rod 13 stops working and maintains the current height. After the position is adjusted, start the motor 4 in the power assembly. Its output shaft drives the bidirectional threaded rod 12 to rotate. Since the two side plates 9 are threadedly connected to the bidirectional threaded rod 12, and the side plates 9 are located in the slide groove 15 and are slidably connected to the slide groove 15, the rotation of the bidirectional threaded rod 12 causes the two side plates 9 to move closer to each other along the slide groove 15. The clamps 8 on the side plates 9 then move closer to the needle bed base body 3. Since the clamps 8 are adapted to the needle bed base body 3, they can finally firmly clamp the needle bed base body 3 from both sides, providing a stable clamp for flipping.

[0044] After the needle bed base body 3 is clamped, the motor 6 on the bearing plate 2 5 is started. The output shaft of the motor 2 6 is tightly welded to one of the clamps 8, and the other clamp 8 is rotatably connected to the side plate 9. When the motor 2 6 rotates, it drives the connected clamp 8 to rotate. Through friction, the needle bed base body 3 rotates synchronously. The other clamp 8 rotates on the side plate 9 accordingly as the needle bed base body 3 rotates, thereby realizing the flipping of the needle bed base body 3. It can be flipped to a specified angle as needed.

[0045] After the flipping is completed, first control motor 4 to rotate in the reverse direction, driving the bidirectional threaded rod 12 to rotate in the reverse direction, so that the two side plates 9 move away from each other along the slide groove 15. The clamp 8 releases the needle bed base body 3. Then, start the electric push rod 13 to retract it, driving the bearing plate 2 and the side plates 9 on it, the clamp 8 and other components to slide down along the fixed column 14 and return to the initial lower position. At the same time, motor 6 rotates in the reverse direction, so that the clamp 8 returns to the initial angle. The entire fixture returns to the initial state and waits for the next operation. The overall device is easy to operate, has high flipping efficiency, adjusts the position of the needle bed base, has a simple structure, and low maintenance cost. The flipping fixture not only improves work efficiency and reduces maintenance costs, but also enhances practicality and reliability, bringing great convenience to the use and maintenance of the needle bed base.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
