The clamping sliding rod 2 is fitted into the through hole of the sliding fit sleeve 14. A rotating connecting end 24 is integrally provided at the upper end of the clamping sliding rod 2. A rotating connecting hole 25 is machined on the rotating connecting end 24. The two sides of the rotating connecting end 24 are rotatably connected to the lower ends of connecting plate 15 and connecting plate 26, respectively. The upper ends of connecting plate 15 and connecting plate 26 are rotatably connected to one end of a transition connecting bent plate 17. The other two ends of the transition connecting bent plate 17 are rotatably connected to connecting plate three 19 and connecting plate four 20 respectively. The other ends of connecting plate three 19 and connecting plate four 20 are rotatably connected to one end of the transition connecting straight plate 22. An upper support column 9 is fixedly installed on the clamping support beam 4 near the end. A clamping support bar 10 is fixedly installed on the upper end of the upper support column 9. A hinge seat 23 is fixedly installed on the clamping support bar 10. The other end of the transition connecting straight plate 22 is rotatably connected to the hinge seat 23. A support connecting groove 18 is opened at the end of the clamping support bar 10 near the pressing sliding rod 2. The two sides of the support connecting groove 18 are rotatably connected to the bend of the transition connecting bent plate 17.

[0024] The transition connecting plate 17 is a right-angled bent plate structure. The bending position and both ends of the transition connecting plate 17 are machined with mating through holes for assembly with the connecting parts.

[0025] The main body of the pressing sliding rod 2 is a cylindrical structure, the rotating connection end 24 is a milled flat structure, the pressing plate 1 is fixedly set at the lower end of the pressing sliding rod 2, and a reinforcing fixing sleeve 13 is provided at the connection position between the pressing plate 1 and the pressing sliding rod 2 to improve the connection stability between the pressing plate 1 and the pressing sliding rod 2.

[0026] A fixed connecting block 21 is fixedly installed on the upper outer side of the connecting plate 3 19 and the connecting plate 4 20. A tensioning operating rod 11 is fixedly installed on the side of the fixed connecting block 21. The tensioning operating rod 11 has an L-shaped structure. A handle 12 is provided at the end of the tensioning operating rod 11. A comfortable hand grip is provided at the handle 12.

[0027] Main support rods 3 are fixedly installed at both ends of the bottom surface of the clamping support beam 4. A support platform 5 is installed at the lower end of the main support rod 3. A positioning seat 7 is fixedly installed on the support platform 5. A positioning block 8 is installed on the positioning seat 7. The positioning block 8 has a V-shaped block structure. There are two main support rods 3, which are located at opposite corners of the support platform 5.

[0028] A base plate 6 is fixedly installed below the support plate 5. The support plate 5 and the base plate 6 are parallel to each other. The bottom surface of the base plate 6 is machined with a keyway to facilitate installation with the machine tool worktable.

[0029] The working principle of this utility model is as follows: When machining the flange fork, the base plate 6 is fixedly installed on the workbench of the equipment. The handle 12 is pulled away from the end of the clamping support bar 10. The handle 12 drives the fixed connecting block 21 to rotate through the tensioning operating rod 11. The fixed connecting plate 3 19 and the connecting plate 4 20 drive the transition connecting bent plate 17 and the transition connecting straight plate 22 to rotate. The transition connecting straight plate 22 rotates relative to the hinge seat 23. The transition connecting bent plate 17 rotates relative to the support connecting groove 18 of the clamping support bar 10. During the rotation of the transition connecting bent plate 17 along the support connecting groove 18, it drives the connecting plate 1 15 and the connecting plate 2 16 to rotate and move upward. The lower end of the connecting plate 1 15 and the connecting plate 2 16 drives the rotating connecting end 24 to move upward, which in turn drives the pressing sliding rod 2 to move upward along the sliding fit sleeve 14. The pressing plate 1 moves upward, providing position space for the flange fork. Then, the flange fork is placed on the V-shaped support surface of the positioning block 8.

[0030] When the handle 12 is pulled in the opposite direction, the connecting plate 15, connecting plate 26, connecting plate 319, transition connecting bent plate 17, and transition connecting straight plate 22 move accordingly, causing the pressing sliding rod 2 to move downward along the sliding fit sleeve 14. The pressing plate 1 moves downward to press and fix the top surface of the flange fork, thus completing the quick clamping of the flange fork.

[0031] The quick clamping device of this utility model, through the setting of connecting plate 15, connecting plate 16, connecting plate 19, connecting plate 20, transition connecting bent plate 17, fixed connecting block 21 and tightening / loosening operating rod 11, can drive the pressing sliding rod 2 to move up and down along the sliding fitting sleeve 14 through a crank-connecting rod structure, thereby driving the pressing plate 1 to move up and down, realizing the quick locking and loosening of the flange fork. The clamping device is equipped with a hinge seat 23 and a transition connecting straight plate 22 to support the clamping position and limit the loosening position. Compared with the crank-connecting rod, the tightening / loosening operating rod 11 is an extended structure with a longer lever arm, making the tightening / loosening operation process more labor-saving. The structure is simple and practical.
