[0002] A cement sampler is a tool or device used to collect cement samples. It is usually made of special materials. During the preparation of the cement sampler, the CNC lathe can complete a series of processing procedures, including turning, milling, drilling and other operations. By controlling the precise positioning and movement of the tool by the control system, the cement sampler can be precisely processed and its shape controlled to ensure its quality and accuracy. By automatically controlling the movement and processing path of the tool, the cement sampler can be processed with high precision. Compared with traditional manual operations, CNC lathes can provide higher processing accuracy and repeatability, reduce human errors, and ensure the accuracy of the cement sampler.

[0003] However, when the CNC lathe is used to prepare the cement sampler, since the empty tube of the cement sampler is a hollow tube, the clamping force and the vibration generated by the processing operation can easily cause the empty tube to deform, resulting in defective products, causing the finished product to be unusable or to have poor performance.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0022] Reference Figures 1 to 4 In the embodiment of the utility model, a CNC lathe for preparing a cement sampler includes: a lathe body 1, a main shaft 2 is provided at one end inside the lathe body 1, a chuck 3 is fixedly connected to one end of the main shaft 2, a connecting column 4 is fixedly connected to the middle of one end of the main shaft 2, an externally threaded rod 5 is fixedly connected to one end of the connecting column 4, a supporting inner sleeve 1 6 is provided at one end of the external threaded rod 5, a supporting inner sleeve 2 7 is provided at the other end of the external threaded rod 5, and a supporting inner sleeve 3 8 is provided at the other end of the external threaded rod 5.

[0023] Reference Figure 1 , Figure 2 and Figure 5 A support frame 9 is provided at the other end of the lathe body 1, and a connecting plate 10 is fixedly connected to one end of the inner side of the support frame 9. A telescopic cylinder 11 is fixedly connected to one end above the connecting plate 10. A curved support frame 12 is provided at the movable end of the telescopic cylinder 11. The movable end of the telescopic cylinder 11 penetrates the support frame 9 and is fixedly connected to the curved support frame 12. The curved support frame 12 is movably plugged into the support frame 9.

[0024] By adopting the above scheme, after the chuck 3 clamps and fixes the empty tube of the cement sampler, the arc surface support frame 12 can be driven to move upward by the telescopic cylinder 11, so that the arc surface of the arc surface support frame 12 supports the empty tube, further consolidating its stability during processing.

[0025] Reference Figure 1 and Figure 2 A tool holder 13 is provided at the other end of the lathe body 1, a lathe base 14 is fixedly connected to one end below the lathe body 1, a control panel 15 is provided at the other end of the lathe body 1, and a tailstock 16 is provided at the other end of the lathe body 1.

[0026] By adopting the above scheme, through the functions of the tool holder 13, the control panel 15 and the tailstock 16, the empty tube or other parts of the cement sampler can be processed when the cement sampler is prepared.

[0027] Reference Figures 1 to 4 A motor and a gear transmission assembly are integrated inside the lathe body 1, the motor output end is fixedly connected to the spindle 2, the external threaded rod 5 passes through the chuck 3, and the external threaded rod 5 is threadedly connected to the support inner sleeve 1 6, the support inner sleeve 2 7 and the support inner sleeve 3 8.

[0028] By adopting the above scheme: through the arrangement of supporting inner sleeve 1 6, supporting inner sleeve 2 7 and supporting inner sleeve 3 8 with different outer diameters, a supporting inner sleeve matching the inner diameter of the empty tube of the cement sampler to be processed can be selected, and then sleeved on the outside of the external threaded rod 5. After the chuck 3 fixes the empty tube, the supporting inner sleeve plays a supporting role in the inner cavity of the empty tube.

[0029] The working principle of the utility model is: when the empty tube of the cement sampler is processed, through the connection relationship between the external threaded rod 5 and the supporting inner sleeve 1 6, the supporting inner sleeve 2 7 and the supporting inner sleeve 3 8, according to the inner diameter size of the empty tube of the cement sampler to be processed, multiple groups of supporting inner sleeves 1 6 or supporting inner sleeves 2 7 or supporting inner sleeves 3 8 with matching outer diameters can be set, and sleeved on the outside of the external threaded rod 5, and then the empty tube is put into the chuck 3, and the supporting inner sleeve is inserted into the empty tube, and then the chuck 3 is used to fix the empty tube so as to perform grinding or turning operations, so that the inner cavity of the empty tube can be supported when the empty tube is processed to avoid the clamping force being too large. The large size and the vibration generated by the processing operation cause the empty tube to deform, thus resulting in defective products, which make the finished products unusable or have poor use effects, and waste the materials for preparing the cement sampler. By setting the support inner sleeve 1 6, the support inner sleeve 2 7 and the support inner sleeve 3 8 with different outer diameters, the empty tubes of cement samplers with different inner diameters can be processed; through the connection relationship between the support frame 9, the connecting plate 10, the telescopic cylinder 11 and the arc surface support frame 12, after clamping and fixing the empty tube, the telescopic cylinder 11 drives the arc surface support frame 12 to move upward, so that the arc surface of the arc surface support frame 12 supports the empty tube, further consolidating its stability during processing.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
