[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0022] This utility model embodiment provides a clamping fixture for a CNC sawing machine, such as... Figure 1-5As shown, the clamping fixture of the CNC sawing machine includes: a placement plate 1, which is mounted on the CNC sawing machine and is used to place the sheet metal to be processed; a support frame 101 is fixedly mounted on the placement plate 1; a plurality of first telescopic rods 2 fixedly mounted on the placement plate 1; a pusher frame 3 fixedly mounted on the output shaft of the plurality of first telescopic rods 2, which is used to push the sheet metal on the placement plate 1; a plurality of second telescopic rods 4 fixedly mounted on the pusher frame 3; a plurality of fixing blocks 5 respectively fixedly mounted on the output shaft of the plurality of second telescopic rods 4, which are used to fix the sheet metal on the placement plate 1; a fixing mechanism assembled on the support frame 101, which is used to fix the transverse center position of the sheet metal on the placement plate 1; and an adjustment mechanism provided on the support frame 101 and the fixing mechanism, which is used to adjust the working position of the fixing mechanism.
[0023] In this embodiment, during use, the placement plate 1 is installed on the longitudinal moving device of the CNC sawing machine. The sheet metal is then placed on the placement plate 1. The controller activates the first telescopic rod 2, which moves the pusher 3 to contact the right edge of the sheet metal. Then, the controller activates the second telescopic rod 4, which moves the fixing block 5 downwards to fix the top of the right edge of the sheet metal. Based on the size of the sheet metal, the position of the fixing mechanism is adjusted by controlling the activation of the adjustment mechanism, thereby adjusting the fixing mechanism to the lateral center position of the sheet metal (or another corresponding lateral position). Then, the fixing mechanism is activated to move downwards to apply force to the center position of the sheet metal for fixation. This effectively improves the stability of the sheet metal fixation, reducing sheet metal shaking and improving the stability during sheet metal sawing, thus improving the accuracy of sheet metal processing. This is achieved through the longitudinal moving mechanism of the CNC sawing machine. The mechanism drives the board to move longitudinally, and under the action of the saw head on the CNC sawing machine, the board can be sawn. After one sawing operation is completed, the controller activates the fixing mechanism to disengage from the center position of the board. At the same time, the controller activates the second telescopic rod 4 to move the fixing block 5 to disengage from the top right side of the board. Then, the controller activates the first telescopic rod 2 to move the pusher 3 to move the board a certain distance. After the movement is completed, the controller activates the second telescopic rod 4 to move the fixing block 5 down to fix the top right side of the board again. Then, the controller activates the adjustment mechanism again to adjust the lateral position of the fixing mechanism, so that the fixing mechanism can be well aligned with the lateral center position of the board. Then, the controller activates the fixing mechanism again to fix the center position of the board. This operation is repeated to perform continuous sawing operations on the board.
[0024] In a further preferred embodiment of the present invention, the fixing mechanism includes: a mounting plate 6 disposed on the support frame 101; a plurality of third telescopic rods 7 fixedly mounted on the mounting plate 6, and a pressure plate 701 fixedly mounted on the output shaft of the plurality of third telescopic rods 7, the pressure plate 701 being used to fix the top of the plate on the placement plate 1.
[0025] In this embodiment, when using the fixing mechanism, the controller activates the third telescopic rod 7 to move the pressure plate 701 downward, thereby fixing the center position of the top of the plate and improving the stability of the plate fixing.
[0026] In a further preferred embodiment of the present invention, the adjustment mechanism includes: a motor 8 fixedly mounted on the support frame 101; a lead screw 9 rotatably mounted on the support frame 101, one end of the lead screw 9 being fixedly connected to the output shaft of the motor 8; and a mounting block 10 threaded onto the lead screw 9, the mounting block 10 being fixedly connected to the mounting plate 6.
[0027] In this embodiment, when using the adjustment mechanism, the controller starts the motor 8 to drive the lead screw 9 to rotate. A limit rod is fixedly installed on the support frame 101. The limit rod and the mounting block 10 are slidably connected. The limit rod limits the mounting block 10, thereby causing the lead screw 9 to drive the mounting block 10 to move, thereby adjusting the lateral use position of the pressure plate 701. This facilitates the alignment of the lateral center position of the pressure plate 701 with that of the plate. At the same time, the lateral use position of the pressure plate 701 is adjusted according to the actual use requirements.
[0028] In a further preferred embodiment of this utility model, multiple limiting mechanisms are provided on both sides of the placement plate 1. The limiting mechanisms are used to limit the placement position of the plate. The limiting mechanisms include: a connecting plate 11 fixedly installed on the placement plate 1; a fourth telescopic rod 12 fixedly installed on the connecting plate 11, and a limiting plate 13 fixedly installed on the output shaft of the fourth telescopic rod 12. The limiting plate 13 is used to limit the plate placed on the placement plate 1.
[0029] In this embodiment, after the board is placed on the placement plate 1, multiple fourth telescopic rods 12 on both sides of the placement plate 1 drive multiple limiting plates 13 to move relative to each other and contact the front and rear edges of the board, thereby limiting and fixing the board and further improving the stability of the board clamping and fixing, preventing the board from shifting forward and backward. At the same time, when the pusher 3 pushes the board, the controller will activate the fourth telescopic rods 12 to drive the limiting plates 13 to move and disengage from the limiting of the board. After the movement is completed, the controller will activate the fourth telescopic rods 12 again to drive the multiple limiting plates 13 to move and limit the edges of the board.
[0030] In a further preferred embodiment of this utility model, a positioning mechanism is provided on the limiting plate 13. The positioning mechanism is used to position the edge of the plate on the placement plate 1. The positioning mechanism includes: a fifth telescopic rod 14 fixedly installed on the limiting plate 13; and a positioning block 15 fixedly installed on the output shaft of the fifth telescopic rod 14. The positioning block 15 is used to position the top of the plate.
[0031] In this embodiment, after the limiting plate 13 contacts the edge of the board, the controller activates the fifth telescopic rod 14 to move the positioning block 15 downward to fix the top of the front and rear edges of the board. By clamping and fixing the board in multiple directions, the stability of the board during sawing is effectively improved, thereby improving the accuracy of the board processing. Similarly, when the pusher 3 pushes the board, the controller activates the fifth telescopic rod 14 to move the positioning block 15 to disengage from the board. After the movement is completed, the controller activates the fifth telescopic rod 14 again to move the positioning block 15 to fix the board.
[0032] In a further preferred embodiment of the present invention, a slider 16 is fixedly installed on the mounting plate 6, and a sliding rod 17 is fixedly installed on the support frame 101, wherein the slider 16 and the sliding rod 17 are slidably connected.
[0033] In this embodiment, the stability of the mounting plate 6 during movement can be improved by the cooperation of the slider 16 and the slide bar 17.
[0034] In a further preferred embodiment of this utility model, friction pads are provided on the fixing block 5, the pressure plate 701, the limiting plate 13 and the positioning block 15.
[0035] In this embodiment, the friction pad can increase the friction between the pad and the plate, thereby improving the stability of clamping and fixing the plate.
[0036] In summary, compared with related technologies, this device can clamp and fix the board in multiple directions, thereby reducing the swaying and displacement of the board, improving the stability of the board sawing process, and thus improving the accuracy of the board processing.
[0037] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
