[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-6 As shown, this utility model is a workpiece clamping fixture for CNC machine tools, including a machine tool 1. A support plate 2 is provided inside the machine tool 1. A placement platform 3 is provided on the top of the support plate 2. A plurality of clamping components 4 are provided on the outer surface of the placement platform 3. An adjustment component 5 is provided inside the placement platform 3 corresponding to the clamping components 4. The clamping components 4 and the adjustment components 5 are poweredly connected. A drive component 6 is provided inside the placement platform 3. The drive component 6 is poweredly connected to the plurality of adjustment components 5.

[0030] The adjustment component 5 is used to support the clamping component 4 so that the clamping component 4 can be adjusted in position on the outside of the placement platform 3 according to the end face of the irregular part. The driving component 6 is used to push the adjustment component 5 so that the clamping component 4 can clamp and fix the irregular part on the placement platform 3.

[0031] When clamping and fixing irregularly shaped workpieces, the clamping components 4 on several adjusting components 5 are pushed. At this time, the adjusting components 5 can guide the clamping components 4 and make the clamping components 4 rotate on the outside of the placement platform 3 according to the outer surface of the irregularly shaped workpiece. After the adjustment of the clamping components 4 is completed, the irregularly shaped workpiece is placed on the top of the placement platform 3, and then the driving component 6 is driven, so that the driving end of the driving component 6 pulls the clamping components 4 through the adjusting components 5, thereby making the clamping components 4 complete the clamping and fixing of the irregularly shaped workpiece.

[0032] By pushing the clamping assembly 4, it can rotate outside the placement table 3, and the clamping end of the clamping assembly 4 can be adjusted according to the outer surface of the irregular workpiece. This setting allows the driving assembly 6 to pull the clamping assembly 4 through the adjusting assembly 5, so that when the clamping assembly 4 clamps and fixes the irregular workpiece, the clamping end of the clamping assembly 4 can be in close contact with the outer surface of the irregular workpiece, thereby avoiding the phenomenon of shaking that easily occurs when processing the irregular workpiece. At the same time, since the adjustable clamping assembly 4 can adapt to irregular workpieces of different specifications, the overall applicability of the clamping fixture is improved.

[0033] In one embodiment, the clamping assembly 4 includes an L-shaped movable plate 401. Multiple L-shaped movable plates 401 are provided on the outside of the placement platform 3. An adjusting screw 402 is threadedly connected to the inside of the L-shaped movable plate 401. One end of the adjusting screw 402 is rotatably connected to a clamping plate 403. A limiting rod 404 is fixedly connected to the outside of the clamping plate 403. The limiting rod 404 is movably connected to the L-shaped movable plate 401. The other end of the adjusting screw 402 passes through the L-shaped movable plate 401 and is fixedly connected to a control disk 405.

[0034] After the L-shaped moving plate 401 is positioned according to the outer surface of the irregular workpiece, the adjusting screw 402 is rotated by the control panel 405, so that the adjusting screw 402 can push the clamping plate 403. At this time, the clamping plate 403 moves inside the L-shaped moving plate 401 under the push of the adjusting screw 402 and the guidance of the limiting rod 404. The clamping plate 403 inside the L-shaped moving plate 401 can be set to adjust its position, so that when clamping and fixing the irregular workpiece, the drive assembly 6 can drive several clamping plates 403 at the same time, so that the clamping plates 403 can also contact the outer surface of the irregular workpiece, making it more convenient to fix the irregular workpiece.

[0035] In one embodiment, the adjustment component 5 includes an adjustment groove 501. Multiple adjustment grooves 501 are provided on the outer side of the placement platform 3 corresponding to the L-shaped moving plate 401. An adjustment block 502 is movably connected inside the adjustment groove 501. The L-shaped moving plate 401 is movably connected to the corresponding adjustment block 502. A ring frame 503 is fixedly connected to the top of the placement platform 3. The adjustment block 502 is movably connected to the ring frame 503.

[0036] By pushing the adjusting block 502, the annular frame 503 can guide the adjusting block 502, allowing it to move in an arc shape inside the adjusting groove 501. The moving adjusting block 502 then drives the L-shaped moving plate 401 to rotate outside the placement platform 3, so that the clamping plate 403 on the L-shaped moving plate 401 can correspond to the outer surface of the irregular workpiece. The aforementioned setting of the annular frame 503 ensures that the adjusting block 502 will not move out of the adjusting groove 501 during movement.

[0037] In one embodiment, for the aforementioned adjusting block 502, a locking bolt 504 is threadedly connected to the outer side of the adjusting block 502, and a plurality of arc-shaped adjusting frames 505 are provided on the inner L-shaped moving plate 401 of the placement platform 3. The L-shaped moving plate 401 is movably connected to the corresponding arc-shaped adjusting frame 505, and the plurality of arc-shaped adjusting frames 505 are arranged alternately up and down.

[0038] After the adjusting block 502 moves to the appropriate position, the locking bolt 504 is rotated, causing the bottom end of the locking bolt 504 to contact the outer surface of the placement platform 3. At this point, due to the high friction between the locking bolt 504 and the placement platform 3, the adjusted block 502 will not move arbitrarily. When the adjusting block 502 moves inside the adjusting groove 501, the L-shaped moving plate 401 slides on the outer surface of the arc-shaped adjusting frame 505 under the influence of the adjusting block 502. When clamping and fixing irregularly shaped workpieces, the arc-shaped adjusting frame 505 is pulled, thereby causing the L-shaped moving plate 401 to move. The L-shaped movable plate 401 moves under the pull of the arc-shaped adjusting frame 505. At this time, the arc-shaped adjusting frame 505 can drive the clamping plate 403 to move towards the axis on the placement table 3 through the L-shaped movable plate 401. This setting ensures that no matter how the L-shaped movable plate 401 is adjusted, the clamping plate 403 can move towards the axis on the placement table 3 during the subsequent clamping process, so that the clamping of irregular workpieces can be performed normally. At the same time, since several arc-shaped adjusting frames 505 are arranged vertically and vertically, there will be no movement interference when several arc-shaped adjusting frames 505 are pulled at the same time.

[0039] In one embodiment, the drive assembly 6 includes an arc-shaped drive frame 601, which is fixedly connected to an arc-shaped adjustment frame 505. A drive plate 602 is fixedly connected to the outer surface of the arc-shaped drive frame 601. A plurality of drive screws 603 are rotatably connected to the inner wall of the placement platform 3, and the plurality of drive screws 603 are threadedly connected to the corresponding drive plates 602.

[0040] By rotating the drive screw 603, the drive screw 603 can drive the arc-shaped adjustment frame 505 to move through the drive plate 602 and the arc-shaped drive frame 601. Since the drive plate 602 is located under the arc-shaped adjustment frame 505 under the support of the arc-shaped drive frame 601, the drive plate 602 will not cause any obstruction when the L-shaped moving plate 401 moves.

[0041] In one embodiment, for the aforementioned placement platform 3, an installation cylinder 604 is fixedly installed on the top of the inner wall of the placement platform 3, one end of each of the plurality of drive screws 603 extends through into the interior of the installation cylinder 604 and is fixedly connected to a bevel gear 605, the plurality of bevel gears 605 meshing together, and a drive motor 606 is fixedly installed on the top of the support plate 2, the output end of the drive motor 606 being fixedly connected to one of the drive screws 603.

[0042] By driving the drive motor 606, one of the drive screws 603 is rotated. The rotating drive screw 603 is driven to rotate synchronously through the meshing bevel gear 605. Thus, the drive screws 603 can drive the corresponding drive plate 602, and the clamping plates 403, driven by the corresponding L-shaped moving plate 401, complete the clamping and fixing of the irregular workpiece.

[0043] In one embodiment, for the aforementioned placement platform 3, a connecting ring 7 is fixedly connected to the outer side of the placement platform 3, and the connecting ring 7 is fixedly installed on the top of the support plate 2.

[0044] The mounting platform 3 can be mounted on top of the support plate 2 by means of the fixing bolts and connecting ring 7. This arrangement makes it easier to maintain the components inside the mounting platform 3.

[0045] Through the above technical solution, 1. By pushing the clamping component 4, the clamping component 4 can rotate outside the placement table 3, and the clamping end of the clamping component 4 can be adjusted according to the outer surface of the irregular workpiece. This setting allows the driving component 6 to pull the clamping component 4 through the adjusting component 5, and when the clamping component 4 clamps and fixes the irregular workpiece, the clamping end of the clamping component 4 can be in close contact with the outer surface of the irregular workpiece, thereby avoiding the phenomenon of shaking that easily occurs when processing the irregular workpiece; at the same time, because the clamping component 4 can be adjusted... The holding component 4 can adapt to different specifications of irregularly shaped workpieces, thereby improving the overall applicability of the clamping fixture; 2. The adjusting screw 402 is rotated by the control panel 405, so that the adjusting screw 402 adjusts the position of the clamping plate 403 according to the actual situation. This setting allows the driving screw 603 connected by bevel gear 605 to drive the corresponding driving plate 602 synchronously. At the same time, several clamping plates 403 can be in close contact with the corresponding outer surface of the irregularly shaped workpiece while moving synchronously. The whole process only requires control of one driving source.
