[0036] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0037] Refer to Figure 1 and Figure 2, an embodiment provided by the present utility model: A workpiece handling device for a numerically controlled lathe, comprising two protective shells 1. Electric telescopic rods 3 are fixedly connected to the front and rear sides of the inner top wall of the top protective shell 1. The output ends of the two electric telescopic rods 3 are fixedly connected with displacement plates 4. The two displacement plates 4 are connected by an elastic band 8. Threaded knobs 5 are threadedly penetrated through the left and right sides of the top walls of the two displacement plates 4. The bottom ends of the plurality of threaded knobs 5 are threadedly connected with fixing plates 6. A foam pad 9 is fixedly installed on the inner bottom wall of the bottom protective shell 1. A bottom shell 18 is arranged on the bottom wall of the bottom protective shell 1. Handling grooves 17 are opened on the front and rear sides of the bottom protective shell 1. Protective corner pads 10 are fixedly connected to the four corners of the inner wall of the bottom protective shell 1. Locking components are arranged on the left and right sides of the top protective shell 1. A cleaning mechanism 2 is arranged on the inner wall of the bottom shell 18;

[0038] Specifically, turn the workpiece into the interior of the bottom protective shell 1. Soft foam pads 9 are laid inside the shell. These foam pads 9 can effectively absorb and disperse the impact force, thereby reducing the direct damage to the workpiece. To further enhance the protection of the workpiece, protective corner pads 10 are installed at the four corners of the protective shell 1. These protective corner pads 10 are made of elastic materials and can effectively protect the edges and corners of the workpiece, preventing collision and wear during transportation. At the top of the protective shell 1, the fixing plate 6 is fixed to the bottom of the displacement plate 4 through the threaded knob 5, and the displacement plate 4 is driven by two electric telescopic rods 3. When it is necessary to fix the workpiece, just start the electric telescopic rod 3 to make the displacement plate 4 drive the fixing plate 6 to move to an appropriate position for fixing. By rotating the threaded knob 5, the fixing plate 6 can be replaced, so that the device can adapt to workpieces of different specifications and meet various fixing requirements.

[0039] Refer to Figure 1 and Figure 3 , the cleaning mechanism 2 includes a plurality of return springs 201. The far - away sides of the plurality of return springs 201 are respectively fixedly connected to the left and right sides of the inner wall of the bottom shell 18. Grooves 202 are opened on the left and right sides of the inner wall of the bottom shell 18. The adjacent sides of the plurality of return springs 201 are fixedly connected with cleaning shells 203. Cleaning sponge brushes 204 are fixedly installed on the inner walls of the two cleaning shells 203. A hydraulic rod 205 is fixedly connected to the middle of the inner bottom wall of the bottom shell 18. The output end of the hydraulic rod 205 is fixedly connected with a clamping plate 206;

[0040] Specifically, the inner wall of the clamping plate 206 is clamped with the bottom of the bottom protective shell 1, which improves the stability. By activating the hydraulic rod 205, the lifting of the clamping plate 206 can be easily achieved, thereby driving the two protective shells 1 to finely adjust the height. When the bottom protective shell 1 is displaced, the cleaning sponge brush 204 can easily reach and clean the handling groove 17, effectively reducing the risk of hand slipping caused by dirt. To ensure the close fit of the cleaning sponge brush 204 with the bottom protective shell 1, multiple reset springs 201 are added in the design. These reset springs 201 not only make the cleaning sponge brush 204 closely adhere to both sides of the bottom protective shell 1, but also keep the cleaning surface of the sponge brush always in close contact with the handling groove 17, thereby improving the cleaning effect.

[0041] Referring to Figure 1 , the locking assembly includes two locking plates 11. The adjacent sides of the two locking plates 11 are respectively rotatably connected to the left and right sides of the top protective shell 1. Locking grooves 12 are opened on the left and right sides of the bottom protective shell 1. The bottom parts of the two locking plates 11 are respectively clamped with the corresponding locking grooves 12. The inner wall of the clamping plate 206 is clamped with the bottom of the bottom protective shell 1. A control switch 15 is fixedly connected to the front side of the top protective shell 1; rubber pads 7 are fixedly connected to the left and right sides of the inner top wall of the two fixing plates 6; the control switch 15 is electrically connected to the electric telescopic rod 3;

[0042] Specifically, by rotating the two locking plates 11, the bottom parts of the two locking plates 11 are respectively separated from the corresponding locking grooves 12, thereby achieving the purpose of separating the two protective shells 1. Conversely, locking is completed, which improves the connection effect of the two protective shells 1. Through the control switch 15 electrically connected to the electric telescopic rod 3, the control switch 15 can turn on and off the electric telescopic rod 3. Through multiple rubber pads 7, the fixing effect of the two fixing plates 6 is improved.

[0043] Referring to Figure 2 , a protective cover 16 is arranged on the front side of the control switch 15. The protective cover 16 is rotatably connected to the front side of the top protective shell 1 through a hinge; universal wheels 19 are fixedly installed at the four corners of the bottom wall of the bottom shell 18. A towing rod 20 is fixedly connected to the front side of the bottom shell 18; connecting plates 13 are fixedly connected to the left and right sides of the top wall of the bottom protective shell 1. Card slots 14 are opened on the left and right sides of the bottom wall of the top protective shell 1. The top parts of the two connecting plates 13 are respectively clamped with the corresponding card slots 14;

[0044] Specifically, the protective cover 16 can protect the control switch 15 and prevent accidental touch. Through multiple universal wheels 19, it is convenient to move the device. Through the top parts of the two connecting plates 13 being respectively clamped with the corresponding card slots 14, the connection effect of the two protective shells 1 in the horizontal direction is improved and it is not easy to shake.

[0045] Working principle: When starting to use, by turning the workpiece into the interior of the bottom protective shell 1, the effect of protecting the workpiece is improved through the foam pad 9 and multiple corner pads 10. By starting two electric telescopic rods 3, the two displacement plates 4 drive the corresponding fixing plates 6 fixedly installed through the threaded knobs 5 to displace, so that the top of the workpiece can be fixed. For workpieces of different specifications, the threaded knob 5 can be rotated, and then the fixing plate 6 can be disassembled and replaced to meet the fixing requirements of workpieces of different specifications. Through the elastic band 8, it is prevented that the fixed workpiece has a height difference and then detaches. Rotate the two locking plates 11 so that the bottoms of the two locking plates 11 are respectively engaged with the corresponding locking grooves 12, thus completing the locking work of the two protective shells 1. And through the engagement of the inner wall of the engaging plate 206 with the bottom of the bottom protective shell 1, the stability is improved. By starting the hydraulic rod 205, the engaging plate 206 drives the two protective shells 1 to adjust the height. Through the displacement of the bottom protective shell 1, the cleaning sponge brush 204 can clean the handling grooves 17 on its front and back sides, reducing the situation of hand slipping caused by dirt during handling. Through multiple return springs 201, the cleaning sponge brush 204 can closely adhere to both sides of the bottom protective shell 1, improving the cleaning effect, and thus avoiding the possibility of the fixed box slipping and falling, and improving the safety.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
