[0024] like Figures 1-2 As shown, this application provides a rotary worktable based on laser cutting, including a base 1 and a rotating plate 11 with bearings mounted on the base 1. The rotating plate 11 is adapted to be flipped under the action of an external driving force to adjust the tilt angle of the rotating plate 11.

[0025] Furthermore, a rotating body 2 for placing circular curved parts is installed on the rotating plate 11. The rotating body 2 consists of a rotating seat 21 with bearings mounted on the rotating plate 11 and a top plate 22 fixed on the rotating seat 21. The rotating body 2 is adapted to rotate under the action of external driving force. A sliding groove 221 is provided on the top plate 22. A clamping clamp 3 is provided in the sliding groove 221. The clamping clamp 3 is used to fix the circular curved parts on the rotating body 2.

[0026] The clamping fixture 3 includes a base 31 that is slidably mounted on a slide groove 221, and a pressure head 33 that is hinged to the base 31. A handle 32 is hinged to the top of the tail of the pressure head 33, and a connecting rod (not shown in the figure) is hinged between the handle 32 and the base 31. When the handle 32 is rotated, the handle 32 pulls the pressure head 33 to rotate through the cooperation of the connecting rod, thereby fixing and loosening the circular curved surface part.

[0027] In this application, all external drives mentioned above are driven by motors, and no further limitations are made here. Also, the clamping fixture 3 mentioned above is a clamping device in the prior art. For its specific structure and principle, please refer to the prior art, and no further details are made here.

[0028] like Figures 2-3 As shown, an adjustment mechanism 5 corresponding to the number of clamping fixtures 3 is also provided on the rotating body 2. The adjustment mechanism 5 is used to drive the position of the clamping fixtures 3. The adjustment mechanism 5 includes an adjustment plate 51 with a bearing mounted on the rotating base 21, and an arc groove 511 is provided on the adjustment plate 51. A guide shaft 52 is provided in the arc groove 511. The guide shaft 52 passes through the arc groove 511 and is fixedly connected to the base 31 of the clamping fixture 3. A guide groove 211 is provided on the rotating base 21. The guide groove 211 is set towards the center of the rotating base 21, and the end of the guide shaft 52 is located in the guide groove 211 and is slidably connected to the guide groove 211. The guide groove 211 is used to limit the movement of the guide shaft 52.

[0029] When the adjusting plate 51 is rotated, the guide shaft 52 is pushed to slide along the guide groove 211 by the action of the inner wall of the arc groove 511, and the base 31 is indirectly driven to move along the slide groove 221 under the drive of the guide shaft 52, so that the clamping clamp 3 can move and achieve the purpose of adjusting the position of the clamping clamp 3.

[0030] like Figures 3-4As shown in the drawings, the outer diameter of the adjusting disc 51 is greater than that of the top disc 22, and a positioning unit 4 is mounted at the edge of the adjusting disc 51, which is used to fix the position of the adjusting disc 51, and the positioning unit 4 comprises an arc block 41 fixed at the edge of the adjusting disc 51, a sliding cavity 411 is formed in the arc block 41, and a sliding block 42 is slidably mounted in the sliding cavity 411, and a spring 43 is arranged between the sliding block 42 and the inner wall of the sliding cavity 411, wherein the spring 43 always exerts a spring force on the sliding block 42, and a pull-torque 422 is arranged on the sliding block 42 for driving the sliding block 42 to move, when the pull-torque 422 is pulled, the sliding block 42 moves along the sliding cavity 411 and presses the spring 43, and after the pull-torque 422 is released, the sliding block 42 returns to the original position under the action of the spring 43, and the sliding block 42 is adapted to be locked with the top disc 22 under the cooperation of the spring 43;

[0031] Meanwhile, a first ratchet 421 (as shown in the partial enlarged view of Figure 3 , and a second ratchet 222 (as shown in the partial enlarged view of Figure 2 ) is arranged on the outer ring of the top disc 22 and engaged with the first ratchet 421, and the arc angle of the second ratchet 222 is greater than that of the first ratchet 421, so that when the adjusting disc 51 drives the sliding block 42 to rotate, the first ratchet 421 on the sliding block 42 can always be engaged with the second ratchet 222, and the first ratchet 421 and the second ratchet 222 are adapted to be engaged with each other and fix the position of the adjusting disc 51;

[0032] When it is necessary to fix different inner diameter circular curved surface parts, first pull the pull-torque 422 to drive the sliding block 42 to slide along the sliding cavity 411 and press the spring 43, so that the first ratchet 421 on the sliding block 42 is separated from the second ratchet 222, then rotate the adjusting disc 51 to drive the guide shaft 52 to move along the guide groove 211 under the action of the arc groove 511, and indirectly drive the base 31 to move through the guide shaft 52, so that the compression clamp 3 slides along the sliding groove 221, thereby achieving the purpose of adjusting the position of the compression clamp 3;

[0033] After the compression clamp 3 reaches the position, release the pull-torque 422, and drive the sliding block 42 to return to the original position under the action of the spring 43, so that the first ratchet 421 of the sliding block 42 is engaged with the second ratchet 222 on the top disc 22, and under the action of the spring 43, the sliding block 42 always exerts a pressure on the top disc 22, thereby achieving the purpose of fixing the position of the adjusting disc 51;

[0034] In summary, by adjusting the arc groove 511 on the disc 51, the guide shaft 52 is driven to move along the guide groove 211, and the base 31 is indirectly caused to slide along the sliding groove 221, while the first ratchet 421 on the sliding block 42 is always in meshing state with the second ratchet 222 on the top disc 22 under the action of the spring 43, so that the position of the adjusting disc 51 is fixed, the position adjustment of the pressing clamp 3 is achieved, and the simple adjustment of the pressing clamp 3 is achieved, thereby solving the problem of inconvenient position adjustment of the presser.

[0035] The preferred embodiments of the present application are described above, but the present application is not limited to the above. Those skilled in the art can make various changes and modifications to the present application. Any improvements and refinements within the spirit and principles of the present application, without departing from the principles of the present application, should be considered within the protection scope of the present application.
