[0004] The above-mentioned equipment can avoid deviation during sheet metal processing when in use by setting up anti-deviation mechanisms, drilling machines, support piles and other structures. However, the anti-deviation mechanism of the above-mentioned structure is limited only by the structures on both sides. This limiting method cannot be applied to objects with irregular edges, has a narrow scope of application, poor versatility, and a long screw stroke. The adjustment speed is slow during use and the adaptability is poor. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an anti-deviation structure for sheet metal processing of high-precision CNC machine tools, which solves the current problems of poor versatility and adaptability.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an anti-deviation structure for sheet metal processing of high-precision CNC machine tools, comprising an equipment body, a control panel, a protective ring and a support column, the control panel being arranged at the upper end of the equipment body, the protective ring being arranged on the outer end surface of the equipment body, the support column being arranged on the same side as the upper end of the equipment body, and a placement plate being arranged at the upper end of the equipment body.

[0007] A cylinder is arranged inside the main body of the equipment, a receiving plate is arranged at the bottom end of the cylinder, a position shifting linkage frame is arranged outside the receiving plate, and a correction clamp is arranged at the top end of the position shifting linkage frame.

[0008] The device body also includes a limiting rubber ring, a support frame and an external fixing frame. The limiting rubber ring is fixedly installed on the inner wall end face of the device body, the support frame is fixedly connected to the inner side of the limiting rubber ring, and the external fixing frame is fixedly installed on the top of the device body.

[0009] In some of the embodiments, a circular groove structure is provided at the upper end of the device body, four groups of limiting rubber rings are provided, and five groups of support frames are provided, which are equidistantly distributed in annular shapes on the inner wall of the groove inside the device body.

[0015] In some embodiments, the inner end of the support frame is fixedly connected to the outer wall of the cylinder, and the bottom of the correction clamp is fixedly installed on the top of the displacement linkage frame.

[0016] Compared with the prior art, the present invention provides an anti-deviation structure for high-precision CNC machine tool sheet metal processing:

[0017] The invention discloses an anti-deviating structure for sheet metal processing of high-precision CNC machine tools. The structure comprises a cylinder, a receiving plate, a displacement linkage frame, a correction clamp, an active connection block and a slide rail. When the device is used, the sheet metal processing tool to be used is installed through the bolt structure at the upper end of the external fixing frame. The operator controls the cylinder through the control panel. The cylinder is started under the fixation of the support frame and is pushed downward to apply pressure. The receiving plate is pressed to move downward and drive the outer right-angle connecting frame. The right-angle connecting frame pulls the upper displacement linkage frame through the active connection block, and causes the top of the displacement linkage frame to slide around under the limit support of the slide rail. When the material to be processed is placed flat on the placement plate, the cylinder is controlled to shrink. When the receiving plate moves upward, the right-angle connecting frame pushes upward, causing the movable connecting block to shift outward. At this time, the top of the displacement linkage frame moves inward through the support of the slide rail, and the five sets of correction clamps are driven to close. When the adaptive baffle at the end of the correction clamp contacts the edge of the material to be processed, it is pressed and rotated through the fixed axis until the inner side is close to the edge of the material to be processed. At this time, the CNC machine tool can be used for stamping or punching operations. After the operation is completed again, repeat the above steps to ensure that the adaptive baffle is close to the outer edge of the material to be processed.

[0018] The above settings and processes can make the device have the following beneficial effects:

[0019] Through the cooperation of the cylinder, the receiving plate, the shifting linkage frame and the slide rail, the correction clamp can automatically complete the expansion and contraction movement under the drive of the cylinder, and through the cooperation of the fixed shaft on the outside of the correction clamp and the adaptive baffle, the five groups of correction clamps can rotate the adaptive baffle according to the edge conditions of the processed material during the contraction and closing process, and always keep it close to the outer edge of the processed material to prevent deviation. Compared with the existing two-end clamping anti-deviation method, this structure is not only applicable to more forms of workpieces, but also has a short cylinder stroke, faster adjustment speed and strong adaptability.
