[0021] See also Figures 1 to 5 , the utility model provides a technical solution:

[0022] A square turret lathe with quick clamping and switching includes a mounting seat 1, a mounting block 5 and a tool holder 13. The mounting block 5 is fixedly mounted on the side wall of the mounting seat 1. The outer wall of the mounting block 5 is arranged in a trapezoidal shape. A mounting groove 7 is provided in the middle of the side wall of the mounting block 5. A circular hole 8 is provided in the middle of the mounting groove 7 toward the inside of the mounting block 5. Square grooves 6 are symmetrically provided on the top surface of the mounting block 5. A through hole 9 is provided between two groups of square grooves 6. The inner walls of the through holes 9 are respectively slidably connected to the anti-column 12.

The side walls of the paddle 10 are respectively provided with springs 11 above and below the anti-column 12. The other end of the spring 11 is fixedly mounted to the inner wall of the square groove 6. The circular hole 8 and the through hole 9 are interconnected. The inner wall of the circular hole 8 is slidably connected to the cylinder 15 mounted on the side wall of the tool holder 13.

[0023] The side wall of the mounting block 5 is set to be trapezoidal, and a mounting groove 7 is opened in the middle of the side wall of the mounting block 5, a circular hole 8 is opened in the middle of the mounting groove 7, and square grooves 6 are symmetrically opened on the top surface of the mounting block 5, a through hole 9 is opened between the two groups of square grooves 6, and the inner wall of the through hole 9 is slidably connected to the side wall of the anti-pillar 12, and the outer side walls of the two groups of anti-pillars 12 are fixedly installed with the paddles 10 respectively, so that the cylinder 15 on the side wall of the tool holder 13 can slide in the mounting groove 7 to the circular hole 8, and squeeze the anti-pillar 12 inside the through hole 9 to fix it. Conversely, the maintenance personnel can squeeze the paddle 10 inward to squeeze the cylinder 15 out of the circular hole 8, so as to realize the rapid installation and disassembly of the tool holder 13.

[0024] The side wall of the cylinder 15 is fixedly mounted on the knife seat 13 through an embedded spring, and the side wall of the cylinder 15 is slidably connected to the knife seat 13. By setting the side wall of the cylinder 15 to be fixedly mounted on the knife seat 13 through the embedded spring, when the cylinder 15 slides in the mounting groove 7 to the circular hole 8, it pops out from the inside of the knife seat 13 to fix the knife seat 13.

[0025] The original length diameter of the spring 11 is smaller than the inner wall diameter of the square groove 6. By setting the original length diameter of the spring 11 smaller than the inner wall diameter of the square groove 6, the paddle 10 can be moved in the square groove 6, so that the stop column 12 squeezes the cylinder 15 to realize the disassembly of the knife seat 13.

[0026] The side walls of the tool holder 13 are located on both sides of the cylinder 15 and are provided with trapezoidal grooves corresponding to the outer side walls of the mounting block 5. The side walls of the cylinder 15 are located on the outside of the grooves and are symmetrically provided with reinforcement plates 14. The side walls of the mounting seat 1 are provided with fixing frames 2. The reinforcement plates 14 and the fixing frames 2 are fixedly installed by bolts 3. By symmetrically providing reinforcement plates 14 on the side walls of the tool holder 13 on both sides of the cylinder 15, and the reinforcement plates 14 and the fixing plates 4 fixedly installed on both sides of the mounting seat 1 are reinforced for the second time by bolts 3, the stability of the installation of the tool holder 13 is increased.

[0027] A groove 16 is formed on the side wall of the tool holder 13 away from the cylinder 15, and sliding grooves 17 are formed on the inner walls of both sides of the groove 16. Through grooves 18 are formed on both side walls of the tool holder 13, and the through grooves 18 and the sliding grooves 17 are interconnected. Mounting holes are symmetrically formed on the top and bottom surfaces of the groove 16.

[0028] The inner wall of the slide groove 17 is slidably connected with the spring plunger 20 , and the spring plunger 20 is respectively installed on the side wall of the tool body 19 , and the tool holder 13 is fixedly installed with the tool body 19 through a fixing pin penetrating the mounting hole.

[0029] A groove 16 is provided on the side of the tool holder 13 away from the cylinder 15, and slide grooves 17 are provided on the inner walls on both sides of the groove 16. The slide grooves 17 are engaged with the spring plunger 20, so that the tool body 19 can be disassembled and installed on the tool holder 13, making it convenient for maintenance personnel to disassemble and replace the tool body 19.

[0030] When a worker is using it, he slides the cylinder 15 on the side wall of the tool holder 13 into the installation groove 7. When the cylinder 15 slides to the circular hole 8, the cylinder 15 pops out into the circular hole 8, so that the cylinder 15 squeezes the anti-column 12 inside the through hole 9 and moves to both sides, so that the cylinder 15 enters the through hole 9, and the cylinder 15 is clamped to fix the tool holder 13. The fixing frame 2 and the reinforcement plate 14 are fixed for a second time by the bolts 3. At the same time, the spring plungers 20 on both sides of the tool body 19 are pressed to slide the tool body 19 into the groove 16. When the spring plunger 20 slides to the through groove 18, the tool body 19 is clamped and fixed, which is convenient for maintenance personnel to separately install and disassemble the tool body 19 and the tool holder 13.
