The elastic telescopic component 20 is arranged at one end of the lifting clamping component 21 close to the jacking device 3 and conflicts with the jacking device 3. When the jacking device 3 moves toward the conveying device 1 within the first specified interval, the elastic deformation of the elastic telescopic component 20 drives the lifting clamping component 21 to move synchronously on the conveying device 1, so that the lifting clamping component 21 clamps the jig to be clamped at the specified position.

After the lifting device 3 moves upward and touches the elastic telescopic component 20, the elastic telescopic component 20 will undergo a certain degree of deformation or elastic deformation, and the pressure received will be transmitted to the lifting and clamping component 21, so that the elastic telescopic component 20 drives the lifting and clamping component 21 to move synchronously on the conveying device 1, and then clamps the jig to be clamped at the specified position between the lifting and clamping component 21 and the pressing plate 12. Therefore, the lifting and clamping component 21 is driven by the elastic telescopic component 20 to clamp the jig to be clamped at the lifting and clamping Between the component 21 and the pressing plate 12, compared with directly clamping the jig to be clamped between the lifting clamping component 21 and the pressing plate 12 by driving the lifting clamping component 21 through a rigid straight rod, it is ensured that the elastic telescopic component 20 of the jig to be clamped can absorb and weaken the impact and vibration generated when the jacking device 3 moves upward during the clamping process, thereby reducing the mechanical stress on the clamping device 2 and the jig to be clamped, reducing the risk of damage to the jig to be clamped, and can adaptively adjust according to different workpiece shapes and sizes during the clamping process, ensuring that the clamping process is smoother and more reliable.

A lifting and clamping mechanism, characterized in that: It includes a conveying device, a clamping device and a lifting device; The conveying device is fixedly connected to the external mechanism, and the lifting device is located on one side of the conveying device and forms a first designated interval with the conveying device; The clamping device is arranged opposite to the lifting device; The clamping device includes an elastic telescopic component and a lifting clamping component, the lifting clamping component is slidably connected to the conveying device, the elastic telescopic component is arranged at one end of the lifting clamping component close to the jacking device, and is in conflict with the jacking device. When the jacking device moves toward the conveying device within the first specified interval, the elastic deformation of the elastic telescopic component drives the lifting clamping component to move synchronously on the conveying device, so that the lifting clamping component clamps the jig to be clamped at the specified position.

2. The lifting and clamping mechanism according to claim 1, characterized in that: There are two conveying devices that are arranged opposite to each other. The conveying devices include conveyor belt tracks and at least two connecting plates for connecting lifting and clamping components. The conveyor belt tracks are fixedly connected to an external mechanism. The connecting plate is arranged on one side of the conveyor belt tracks and extends toward the lifting device so that the first specified interval is located between the connecting plate and the lifting device.

3. The lifting and clamping mechanism according to claim 2, characterized in that: A limiting member is disposed on one side of the connecting plate, and the limiting member is adjustably disposed at one end of the connecting plate close to the jacking device.

4. The lifting and clamping mechanism according to claim 2, characterized in that: There are two lifting and clamping components which are arranged opposite to each other, and the lifting and clamping components include a guide rail slider, a lifting plate and a lifting plate. The guide rail slider is slidably connected to the connecting plate through a linear guide rail, the lifting plate is fixedly connected to a side of the guide rail slider away from the connecting plate, and the lifting plate is fixedly connected to an end of the lifting plate away from the lifting device. The lifting plate and the connecting plate are respectively located on opposite sides of the conveyor belt track, and a second specified interval is formed between the lifting plate and the conveyor belt track.

5. The lifting and clamping mechanism according to claim 4, characterized in that: The lifting plate includes a first lifting plate connected to the lifting plate, and a second lifting plate connected to an end of the first lifting plate away from the lifting plate, a side of the first lifting plate away from the connecting plate is provided with an inclined surface inclined toward the second lifting plate, and a width of the second lifting plate is smaller than a width of the first lifting plate away from an end of the second lifting plate.

6. The lifting and clamping mechanism according to claim 4, characterized in that: The elastic telescopic component includes an elastic member and a telescopic rod, the elastic member is arranged in the lifting plate, the telescopic rod is sleeved on one end of the elastic member close to the jacking device, a limiting hole is arranged on the telescopic rod, and the telescopic rod is movably connected in the lifting plate by passing a flat head screw through the limiting hole.

7. The lifting and clamping mechanism according to claim 6, characterized in that: A lifting buffer block is arranged at one end of the telescopic rod away from the elastic member, and the lifting buffer block is made of any one of rubber, polyurethane and foam plastic.

8. The lifting and clamping mechanism according to claim 2, characterized in that: The lifting device includes a driving cylinder, a lifting mounting plate and a lifting base plate, the driving cylinder is arranged on the lifting mounting plate, the lifting base plate is arranged on one end of the lifting mounting plate away from the driving cylinder, the lifting mounting plate and the lifting base plate are connected by a lifting guide rod connected to the driving cylinder, and the length of the lifting base plate is greater than the distance between the two conveying devices.

9. The lifting and clamping mechanism according to claim 8, characterized in that: A floating joint is arranged at one end of the driving cylinder close to the lifting bottom plate, and the floating joint is respectively located in the middle of the lifting installation plate and the lifting bottom plate.

10. A mounting machine, characterized in that: It comprises a lifting and clamping mechanism as described in any one of claims 1-9.
