[0012] As a further description of the above technical solution:

[0013] The telescopic cylinder is connected with an electromagnetic control valve.

[0014] As a further description of the above technical solution:

[0015] The tensioning sleeve is in the shape of a circular tube, and a plurality of air-avoiding grooves are provided at the end of the tensioning sleeve. A deformation clamp is formed between two adjacent air-avoiding grooves.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] In the utility model, the main shaft sleeve is installed in the machine tool box as a structural support. Under the connection action of the pull rod shaft, the telescopic cylinder retracts to drive the tensioning sleeve to slide in the tensioning support sleeve. The tensioning support sleeve squeezes the end of the tensioning sleeve to produce deformation, and then the workpiece inside the tensioning sleeve can be quickly clamped. Similarly, the extension of the telescopic cylinder can reset the tensioning sleeve and release the clamping of the workpiece, making it convenient to clamp the workpiece and improving the clamping efficiency and processing efficiency.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-5 The utility model provides a technical solution: a semi-automatic clamping device for loading and unloading materials without stopping the equipment, comprising:

[0029] The main shaft sleeve 1 is arranged in the machine tool box 2;

[0030] a telescopic cylinder 3, which is provided at one end of the main shaft sleeve 1;

[0031] A tension support sleeve 4, which is provided at the other end of the main shaft sleeve 1;

[0032] a tension sleeve 5 , which is inserted into the tension support sleeve 4 and extends into the main shaft sleeve 1 , with the outer wall of the tension sleeve 5 abutting against the inner edge of the tension support sleeve 4 ;

[0033] A pull rod shaft 6 is provided in the main shaft sleeve 1, and the two ends of the pull rod shaft 6 are respectively connected to the telescopic cylinder 3 and the tension sleeve 5;

[0034] The telescopic cylinder 3 is a double-piston rotary cylinder, and the end of the pull rod shaft 6 is fixedly connected to the telescopic end of the telescopic cylinder 3;

[0035] The telescopic cylinder 3 is connected to an electromagnetic control valve 7 to facilitate the control of the telescopic cylinder 3;

[0036] The tensioning sleeve 5 is in the shape of a circular tube. A plurality of air-avoiding grooves 8 are provided at the end of the tensioning sleeve 5. A deformable clamping jaw 9 is formed between two adjacent air-avoiding grooves 8. An oblique boss 10 is provided on the outer wall of the deformable clamping jaw 9. A guiding slope 11 is provided on the inner edge of the tensioning support sleeve 4. The oblique boss 10 abuts against the guiding slope 11, so that the deformable clamping jaw 9 is squeezed and deformed when a misalignment occurs between the tensioning sleeve 5 and the tensioning support sleeve 4, thereby clamping the workpiece.

[0037] A circular hole slideway 12 is provided inside the main shaft sleeve 1 , and the outer wall of the tension sleeve 5 fits into the inner wall of the circular hole slideway 12 to ensure that the tension sleeve 5 slides smoothly.

[0038] Working principle: First, the workpiece is inserted into the tensioning sleeve 5, and the telescopic cylinder 3 retracts. Under the linkage action of the pull rod shaft 6, the tensioning sleeve 5 slides along the circular hole slide 12. Secondly, when dislocation occurs between the tensioning sleeve 5 and the tensioning support sleeve 4, the guide bevel 11 presses against the oblique boss 10, so that the deformable jaws 9 are squeezed and deformed, and then clamp the workpiece, so that the workpiece is quickly clamped. Then, the steel foot workpiece is turned. Finally, the telescopic cylinder 3 extends. Under the linkage action of the pull rod shaft 6, the tensioning sleeve 5 slides along the circular hole slide 12. After the tensioning sleeve 5 is reset, the deformable jaws 9 are elastically reset, releasing the clamping of the workpiece.
