Description

Technical Field

[0002] PCD tools have the characteristics of high hardness, high compressive strength, good thermal conductivity and wear resistance, etc., and can achieve high processing accuracy and processing efficiency in high-speed cutting. Therefore, the application scope and usage of PCD tools are rapidly expanding, so PCD tools are often used in the processing of end gears. In order to make the cutter head stronger and not fall off, the PCD tool needs to be welded, and the most important process in the welding process is to clamp the PCD tool, so a clamping device is needed;

[0003] Existing public patent: CN202223312799.7 In a PCD tool clamping device, the operator can accurately control the direction of the clamping mechanism by adjusting the screw. At the same time, after the adjustment, the clamping mechanism can be maintained in the specified direction, which effectively increases the stability of the tool during welding and promotes the safety of the device.

[0004] In this comparative example, when the device needs to be moved, the four support blocks need to be flipped in turn to allow the moving wheels to support the ground, and then the support blocks need to be positioned by positioning screws. The whole process is rather cumbersome, which makes it necessary to spend more time to move the clamping device of the PCD tool, thereby reducing the production efficiency of the PCD tool and simultaneously reducing the practicality of the clamping device.

The clamping device body 2 is an existing public patent: CN202223312799.7 A prior art in the clamping device of a PCD tool, which will not be described in detail here;

[0048] Wherein, a bottom groove 3 is provided on the lower surface of the base 1;

[0049] Among them, a rotating shaft 5 is fixedly connected between the inner walls on the front and rear sides of the bottom groove 3;

[0050] Among them, four connecting blocks 15 are provided on the rotating shaft 5 through the bearing rotating sleeve;

[0051] Among them, the outer surfaces of the four connecting blocks 15 on one side away from the rotating shaft 5 are fixedly connected to two fixing blocks 4;

[0052] Among them, a moving mechanism is arranged on the two fixed blocks 4, and the moving mechanism includes a mounting block 6, a wheel 7, a sliding rod 8, a handle 9, a bidirectional threaded rod 10, a supporting spring 11, a positioning block 12, a connecting block 15, a supporting shaft 13 and a rolling block 14.

[0053] Furthermore, the two fixing blocks 4 are arranged in a mirror image;

[0054] Among them, the two fixing blocks 4 are arranged at an angle;

[0055] Among them, four mounting blocks 6 are fixedly connected to the lower surfaces of the two fixing blocks 4;

[0056] Among them, four wheels 7 are installed on the lower surface of the mounting block 6.

[0057] Further, the bidirectional threaded rod 10 is rotatably connected between the left and right inner walls of the bottom groove 3;

[0058] The left end of the bidirectional threaded rod 10 rotates and penetrates the left side surface of the base 1;

[0059] Wherein, the handle 9 is fixedly connected to the left end of the bidirectional threaded rod 10;

[0060] Among them, two sliding rods 8 are fixedly connected between the left and right inner walls of the bottom groove 3;

[0061] The bidirectional threaded rod 10 is located between the two sliding rods 8 .

[0062] Further, the bidirectional threaded rod 10 and the two sliding rods 8 are both located on the lower side of the two fixed blocks 4;

[0063] Wherein, the lower surface of the wheel 7 extends out of the lower surface of the base 1 through the bottom groove 3;

[0064] Among them, two positioning blocks 12 are threadedly sleeved on the outer surface of the bidirectional threaded rod 10;

[0065] The two positioning blocks 12 are located at two opposite threads of the bidirectional threaded rod 10;

[0066] The two positioning blocks 12 are slidably sleeved on the outer surfaces of the two sliding rods 8 .

[0067] Further, the two positioning blocks 12 are in a U shape;

[0068] Among them, the two support shafts 13 are rotatably connected between the two vertical blocks of the two positioning blocks 12;

[0069] Among them, the two positioning blocks 12 are arranged in a mirror image;

[0070] The four rolling blocks 14 are fixedly sleeved on the outer surfaces of the two supporting shafts 13 .

[0071] Furthermore, the upper surfaces of the four rolling blocks 14 are in contact with the lower surfaces of the two fixed blocks 4 .

[0072] Among them, a plurality of support springs 11 are fixedly connected to the top wall of the bottom groove 3;

[0073] The lower ends of the plurality of support springs 11 are fixedly connected to the upper surfaces of the two fixing blocks 4 .

[0074] Furthermore, in this solution, the support spring 11 is in a slightly compressed state, at which time the lower surface of the wheel 7 extends out of the lower surface of the base 1 through the bottom groove 3, and at this time the lower surface of the wheel 7 can contact the ground, thereby pushing the base 1 and the clamping device body 2 to move, and at this time the support force of the support spring 11 on the fixed block 4 is sufficient to support the base 1 and the clamping device body 2 from shaking up and down in the normal processing state and the moving state;

[0075] After the base 1 and the clamping device body 2 are moved to a suitable position, the handle 9 is turned, and the rotation of the handle 9 drives the bidirectional threaded rod 10 to rotate. The rotation of the bidirectional threaded rod 10 synchronously drives the two positioning blocks 12 to move relative to each other, so that the two positioning blocks 12 move away from or close to each other. When the two positioning blocks 12 move away from each other, the upper surfaces of the four rolling blocks 14 roll on the lower surface of the fixed block 4, and because the two fixed blocks 4 are in an inclined state, when the two positioning blocks 12 move away from each other, the four rolling blocks 14 are synchronously driven to push the two fixed blocks 4, so that the two fixed blocks 4 rotate around the rotating shaft 5. During the rotation of the two fixed blocks 4, the support spring 11 is squeezed, so that the support spring 11 is squeezed and deformed, and the wheel 7 is driven to move upward into the bottom groove 3 during the rotation. When the wheel 7 is completely moved into the bottom groove 3 and the lower surface of the base 1 contacts the ground, the lower surface of the base 1 is fitted, thereby positioning the base 1 to prevent the wheel 7 from contacting the ground during the processing. The shaking of the clamping device body 2 affects the processing quality of the pcd tool.

[0076] As mentioned above, the wheel 7 can be hidden by rotating the handle 9 without rotating multiple bolts, which saves manpower and improves the production efficiency of the PCD tool, thereby increasing the practicality of the clamping device.

[0077] As mentioned above, when the handle 9 is turned to make the two positioning blocks 12 move closer to each other, under the action of the release elastic force of the support spring 11, the support spring 11 pushes the two fixing blocks 4 to reset as the two positioning blocks 12 move relative to each other, thereby restoring the wheel 7 to its initial state. The adjustment of the wheel 7 is convenient and quick, saving manpower while improving the production efficiency of the PCD tool, thereby increasing the practicality of the clamping device.

[0078] Working principle: When the device is used, through this solution, the support spring 11 is in a slightly compressed state, at this time, the lower surface of the wheel 7 extends out of the lower surface of the base 1 through the bottom groove 3, and at this time the lower surface of the wheel 7 can contact the ground, thereby pushing the base 1 and the clamping device body 2 to move. At this time, the support force of the support spring 11 on the fixed block 4 is sufficient to support the base 1 and the clamping device body 2 from shaking up and down in the normal processing state and the moving state;

[0079] After the base 1 and the clamping device body 2 are moved to a suitable position, the handle 9 is turned, and the rotation of the handle 9 drives the bidirectional threaded rod 10 to rotate. The rotation of the bidirectional threaded rod 10 synchronously drives the two positioning blocks 12 to move relative to each other, so that the two positioning blocks 12 move away from or close to each other. When the two positioning blocks 12 move away from each other, the upper surfaces of the four rolling blocks 14 roll on the lower surface of the fixed block 4, and because the two fixed blocks 4 are in an inclined state, when the two positioning blocks 12 move away from each other, the four rolling blocks 14 are synchronously driven to push the two fixed blocks 4, so that the two fixed blocks 4 rotate around the rotating shaft 5. During the rotation of the two fixed blocks 4, the support spring 11 is squeezed, so that the support spring 11 is squeezed and deformed, and the wheel 7 is driven to move upward into the bottom groove 3 during the rotation. When the wheel 7 is completely moved into the bottom groove 3 and the lower surface of the base 1 contacts the ground, the lower surface of the base 1 is fitted, thereby positioning the base 1 to prevent the wheel 7 from contacting the ground during the processing. The shaking of the clamping device body 2 affects the processing quality of the pcd tool.
