[0002] In the field of industrial production, medical equipment, automation assembly, lifting frame as an important auxiliary equipment, is widely used in the clamping, positioning and transportation of objects. However, the traditional lifting frame usually has the problems of single function, limited adjustment range, insufficient running stability, etc. For example, the existing device is often difficult to realize the flexible adjustment of the height and angle of the clamp, and lacks effective limiting and dustproof design, which leads to the device to be prone to shaking, deviation or interference by foreign matters during operation, affecting the work efficiency and precision. In addition, the structure of the traditional lifting frame is complex, and the maintenance cost is high, which is difficult to meet the demand of modern industry for high-precision, multi-functional equipment. Therefore, a single-head electric lifting frame with flexible height and angle adjustment function, stable operation and compact structure is needed to solve the above problems.

[0003] In the prior art, although a certain clamping effect can be achieved in use, the existing device lacks flexible angle and height adjustment function and has insufficient stability during operation. In view of this, a single-head electric lifting frame is proposed to solve the above problems. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at providing a single-head electric lifting frame to solve the problems proposed in the background art.

[0006] In use, the third servo motor drives the lower clamping arm to rotate. The lower clamping arm and the upper clamping arm are a single unit, and the upper clamping arm rotates together with the lower clamping arm, allowing the clamping angle to be changed. The second servo motor drives the upper clamping arm to rotate, thereby changing the distance between the upper and lower clamping arms and achieving the clamping effect of the fixture. The first servo motor drives the lead screw to rotate, which drives the moving block to rise and fall, achieving the effect of adjusting the height of the fixture. In addition, the moving block is connected to both guide rail one and guide rail two, so that the moving block is subject to double limiting, which enhances the stability of the moving block's movement. Both guide rail one and guide rail two are inside the housing, effectively preventing dust from affecting the movement of the fixture.

[0007] Preferably, the rotation center of the lower clamping arm is fixedly connected to the output shaft of the servo motor three, and the rotation of the servo motor three will drive the lower clamping arm to rotate.

[0008] Preferably, one end of the mounting column is fixedly connected to the movable block, the movable block is inserted into the guide rail two, and the movable block has a through groove design, the cross section of which fits into the guide rail two.

[0010] Preferably, the output shaft of the servo motor is fixedly connected to the rotation center of the lead screw, and a nut is screwed onto the bottom of the lead screw.

[0011] Preferably, the lead screw and the movable block are connected by a threaded seat. The movable block is inserted into the guide rail.

[0012] Preferably, the upper end of the box is provided with a cover plate, and the lower end of the box is provided with a base plate. The cover plate can play a dustproof role.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This single-head electric lifting frame utilizes a servo motor to drive the lower clamping arm to rotate, which in turn drives the upper clamping arm to rotate synchronously, enabling flexible adjustment of the clamp at a 360-degree angle. A second servo motor controls the distance between the upper and lower clamping arms for precise clamping. Simultaneously, a first servo motor drives a lead screw to rotate, raising and lowering the moving block to achieve precise adjustment of the clamp height. This design allows the equipment to adapt to various working scenarios, meeting clamping requirements at different heights and angles, and improving operational flexibility and efficiency.

[0015] 2. This single-head electric lifting frame, through the through-slot design in the moving block, fits into the second guide rail and is simultaneously inserted into the first guide rail. The limiting effect of the double guide rails ensures the stability of the moving block during lifting and movement. The special design of the first and second guide rails not only prevents the moving block from shifting and shaking, but also plays a role in dust prevention. This structure makes the clamp run smoothly during lifting and rotation, improves the accuracy and reliability of the equipment, and is suitable for high-precision operation scenarios.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a single-head electric lifting frame, including a housing 1, a clamp 5 and a servo motor 8. The housing 1 is equipped with a motor 8 at its upper end, and the clamp 5 is equipped with a clamp 5 on one side of the housing 1. The clamp 5 is equipped with a mounting column 12, the mounting column 12 is equipped with a lower clamping arm 10, the lower clamping arm 10 is equipped with an upper clamping arm 9, and the connection between the upper clamping arm 9 and the lower clamping arm 10 is equipped with a servo motor 8.

[0024] The rotation center of the lower clamping arm 10 is fixedly connected to the output shaft of the servo motor 13. The servo motor 13 can drive the lower clamping arm 10 to rotate 360 ​​degrees, achieving a flexible motion effect.

[0025] One end of the mounting post 12 is fixedly connected to the movable block 4. The movable block 4 is inserted into the guide rail 2 15. The movable block 4 is fitted into the guide rail 2 15 through its internal through groove, so that the movable block 4 can slide smoothly on the guide rail 2 15. This not only ensures the stability of the mounting post 12, but also allows the clamp 5 to be precisely adjusted in the vertical direction. In addition, the guide rail 2 15 is set inside the box 1. The specially shaped movable block 4 can be connected to the guide rail 2 15 and the guide rail 1 14 inside the box 1, which plays a role in dust prevention.

[0028] The lead screw 6 and the moving block 4 are connected by a threaded seat. The moving block 4 is inserted into the guide rail 14. The lead screw 6 is connected to the moving block 4 through the threaded seat. This design allows the rotational motion of the lead screw 6 to be converted into the linear motion of the moving block 4. The moving block 4 is inserted into the guide rail 14. The limiting function of the guide rail 14 ensures that the moving block 4 can only move on the guide rail 14 without deviation or shaking, further improving the stability of the moving block 4 during the lifting process.

[0029] The upper end of the housing 1 is provided with a cover plate 2, and the lower end of the housing 1 is provided with a base 3, which provides stable support for the entire lifting frame.

[0030] Working principle: During use, the servo motor 13 drives the lower clamping arm 10 to rotate. The lower clamping arm 10 and the upper clamping arm 9 are a whole. The upper clamping arm 9 rotates together with the lower clamping arm 10, so that the clamping angle can be changed. The servo motor 11 drives the upper clamping arm 9 to rotate, thereby changing the distance between the upper clamping arm 9 and the lower clamping arm 10, realizing the clamping effect of the fixture 5. The servo motor 8 drives the lead screw 6 to rotate. The rotation of the lead screw 6 can drive the moving block 4 to rise and fall, realizing the effect of adjusting the height of the fixture 5. In addition, the moving block 4 is connected to both guide rail 14 and guide rail 15, so that the moving block 4 is subject to double limiting, which enhances the stability of the movement of the moving block 4. Both guide rail 14 and guide rail 15 are located inside the housing 1, effectively preventing dust from affecting the movement of the fixture 5.
