[0016] The following further describes the present utility model with reference to the drawings.
[0017] As Figures 1 to 3 shown, a clamping cylinder 1 is connected to a base 2 through a cylinder connecting piece. The driving end of the clamping cylinder 1 is connected to one end of a dial 3 through a dial connecting piece 14, and the other end of the dial 3 is an open structure; a clamping device 6 is provided at the other end of the dial 3. A retaining ring 4 is sleeved outside the clamping device 6, and the bottom of the retaining ring 4 is connected to a mounting nut 11; a plurality of set screws 8 are evenly distributed on the inner edge of the mounting nut 11. One end of a spring 10 is connected to the set screw 8, and the other end of the spring 10 is connected to one end of a dial piece 12, and the other end of the dial piece 12 is connected to the clamping device 6.
[0018] The dial 3 is of a C - shaped structure. One end of the dial 3 where it is closed is connected to the clamping cylinder 1 through a dial connecting piece 14, and runners 7 are respectively connected to the inner side of the open end of the dial 3.
[0019] The retaining ring 4 is of an annular structure, and a plurality of buckle grooves 5 are evenly distributed on the inner side wall of the retaining ring 4.
[0020] The clamping device 6 is of an annular structure. A plurality of chuck pieces 13 are evenly distributed in the middle of the clamping device 6, and a chuck connecting cylinder 15 is provided below the chuck pieces 13; a plurality of protrusions 16 are evenly distributed on the outer edge of the chuck connecting cylinder 15, and the protrusions 16 are embedded in the other end of the dial piece 12.
[0021] There are at least 3 set screws 8, and the number of dial pieces 12 is the same as the number of set screws 8.
[0022] The mounting nut 11 is positioned and connected to the clamping device 6 through a number of clamping pins 9.
[0023] The working principle of the utility model is as follows:
[0024] 1. When the clamping device 6 is in its original position, the spring 10 is in a compressed state and is fixed to the set screw 8, which is fixed to the mounting nut 11, thus pushing the dial 12 and keeping the chuck piece 13 on the clamping device 6 in a loose state through the lever principle;
[0025] 2. During automatic machining, the machine tool truss delivers the workpiece 17 to be machined to the machining position;
[0026] 3. The clamping cylinder 1 pushes the dial 3 to the right (as pushed in the direction of the left arrow in Figure 4 ), thus pushing up the snap ring 4 (as pushed in the direction of the right arrow in Figure 4 ), that is, the clamping device 6 is pushed against the workpiece 17 to be ground. At this time, the spring 10 relaxes and pushes the chuck piece 13 to clamp. Since the dial 3 is provided with a runner 7, there is no interference between the dial 3 and the clamping device 6 during machining;
[0027] 4. After machining is completed, the clamping cylinder 1 drives the dial 3 to move the snap ring 4 back to its original position, that is, the clamping device 6 returns to its original position. At this time, the spring 10 compresses and pushes the dial 12 to loosen the chuck piece 13;
[0028] 5. The machine tool truss takes away the finished product.
[0029] The installation and disassembly method of the utility model is as follows:
[0030] 1. During installation, use a screwdriver or similar tool to lift the clamping device 6 onto the clamping pin 9 inside the mounting nut 11;
[0031] 2. Place the clamping device 6 between the bayonet slots 5 of the snap ring 4 and rotate the clamping device 6 counterclockwise until the device can be hooked onto the clamping pin 9;
[0032] 3. Install the set screw 8 and tighten it to complete the installation;
[0033] 4. During disassembly, unscrew the set screw 8 of the clamping device 6;
[0034] 5. Use a screwdriver or similar tool to rotate the clamping device 6 clockwise until the clamping device 6 can be removed from the bayonet slot 5 of the snap ring 4.
