[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figure 1-Figure 4 As shown, the utility model provides a workpiece lifting device for a CNC lathe, comprising a balancing crane 1, a balancing crane 1, an outer wall of the balancing crane 1 movably contacting a lifting ring 2, a bottom of the lifting ring 2 fixedly connected to a support frame 3, an outer wall of the support frame 3 is provided with two mounting holes 4, the inner walls of the two mounting holes 4 are fixedly inserted with bearings 5, the inner walls of the two bearings 5 ​​are fixedly inserted with a bidirectional screw rod 6, an outer wall side of the bidirectional screw rod 6 is fixedly connected to a servo motor 7, an outer wall of the bidirectional screw rod 6 is threadedly connected to two threaded blocks 8, the bottoms of the two threaded blocks 8 are provided with a slide groove 9, the inner walls of the two slide grooves 9 are slidably embedded with a slider 10, one side of the outer wall of the two sliders 10 is fixedly connected to a push block 11, the tops of the two push blocks 11 are fixedly connected to a hydraulic rod 12, and the outer walls of the two threaded blocks 8 are fixedly connected to the outer walls of the two hydraulic rods 12, and one side of the outer wall of the two sliders 10 is fixedly connected to a support plate 13.

[0024] The effect achieved by the entire embodiment 1 is that, after the workpiece is adsorbed and fixed, the two hydraulic rods 12 are first started according to the height of the workpiece, and the telescopic ends of the two hydraulic rods 12 will drive the two support plates 13 to move downward smoothly and accurately until the height of the two support plates 13 is completely flush with the bottom of the workpiece, and then the servo motor 7 is started, and the output end of the servo motor 7 drives the bidirectional screw 6 to rotate. Since the thread designs on both sides of the bidirectional screw 6 are opposite, and the outer wall of the bidirectional screw 6 is threadedly connected to the inner wall of the two threaded blocks 8, the rotation of the bidirectional screw 6 will drive the two threaded blocks 8 to move in opposite directions, and the two threaded blocks 8 will then drive the two support plates 13 to move synchronously until the two support plates 13 are tightly located at the bottom of the workpiece to form a stable support. In this way, even if the workpiece accidentally loosens or falls off for some reason, the two support plates 13 can catch the workpiece in time, thereby effectively preventing accidents or damage to the workpiece.

[0025] Example 2, as Figure 2-Figure 4 As shown, the bottom of the support frame 3 is fixedly connected to the fixing frame 14, and the top of the fixing frame 14 is provided with two first movable grooves 15, and the inner walls of the two first movable grooves 15 are movably inserted with a group of first fixing screws 16, and the outer walls of the two groups of first fixing screws 16 are threadedly connected with first fixing nuts 17, and the tops of the two groups of first fixing nuts 17 are fixedly connected with a load-bearing plate 18, and the tops of the two load-bearing plates 18 are provided with a second movable groove 19, and the inner walls of the two second movable grooves 19 are movably inserted with a group of second fixing screws 20, and the outer walls of the two groups of second fixing screws 20 are threadedly connected with second fixing nuts 21, and the bottoms of the two groups of second fixing screws 20 are fixedly connected with suction cups 22.

[0026] The effect achieved by the entire embodiment 2 is that, by rotating the two sets of first fixing nuts 17, the fixing effect of the two sets of first fixing screws 16 on the load-bearing plate 18 can be released, so that the staff can easily adjust the position of the two load-bearing plates 18, thereby ensuring that the lateral arrangement position of the four suction cups 22 matches the length of the workpiece. Then, by loosening the two sets of second fixing nuts 21, the lock of the two sets of second fixing screws 20 is released, so that the positions of the four suction cups 22 on the two load-bearing plates 18 can be adjusted respectively, so that the longitudinal positions of the four suction cups 22 match the width of the workpiece. Such adjustment ensures that the four suction cups 22 can be accurately and stably located in the key adsorption area of ​​the workpiece, so that the workpiece surface can be more effectively adsorbed. In addition, through this flexible adjustment method, the lifting device can adapt to and adsorb workpieces of different sizes, thereby significantly improving its versatility and practicality.

[0027] Working principle: When in use, first, according to the size of the workpiece to be processed, the two sets of first fixing nuts 17 must be rotated to release the fastening effect of the two load-bearing plates 18, so that the operator can easily adjust the distance between the two load-bearing plates 18, thereby ensuring that the horizontal arrangement of the four suction cups 22 can accurately match the length of the workpiece. Subsequently, by properly loosening the two sets of second fixing nuts 21, the positions of the four suction cups 22 on their respective load-bearing plates 18 can be adjusted independently, so that their longitudinal arrangement is consistent with the width of the workpiece. This adjustment ensures that the four suction cups 22 can accurately and firmly fit the key adsorption areas on the surface of the workpiece, thereby achieving a more reliable and more uniform adsorption effect. Once the four suction cups 22 successfully fix the workpiece, it can be lifted steadily by using the balancing crane 1. Then, according to the actual height of the workpiece, the staff starts the two hydraulic rods 12 and uses their telescopic ends to push the two support plates 13 down smoothly until the height of the support plates 13 is completely flush with the bottom of the workpiece. At this time, the servo motor 7 is started again, and the output end of the servo motor 7 drives the bidirectional screw rod 6 to rotate. With the help of the opposite threads on both sides, and the outer wall of the bidirectional screw rod 6 is threadedly connected to the inner wall of the two threaded blocks 8, the two threaded blocks 8 can be driven to move in opposite directions by rotating the bidirectional screw rod 6, thereby driving the two support plates 13 to move to the bottom of the workpiece, forming a stable support structure, thereby preventing the workpiece from falling off or shifting due to unexpected factors such as wind interference, operational errors, etc. during lifting or processing, and effectively ensuring the safety of the workpiece and the smooth progress of the processing process.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
