[0002] CNC blanking machine is a kind of automation equipment widely used in metal processing, woodworking processing, plastic processing and other fields. It uses computer control system to automatically perform cutting, blanking, slotting and other processing operations according to pre-set programs and parameters, and can achieve high-precision and high-efficiency production and processing.
[0003] CNC blanking machines are widely used in furniture manufacturing, metal processing, architectural decoration, automobile manufacturing and other industries. During processing, the workpiece needs to be positioned and clamped to avoid displacement of the workpiece during processing. At the same time, it can also make the processing more accurate and avoid deviation between the cutting position and the predetermined position, resulting in reduced processing quality. In the prior art, the positioning of the workpiece is usually plane clamping, which results in a smaller clamping contact surface when there are inclined surfaces on both sides of the workpiece, which is easy to damage the workpiece. In view of this, we propose a fixed-point delivery device for CNC blanking machines. Utility Model Content
[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a fixed-point delivery device for a CNC blanking machine, which can solve the problem of small clamping contact surface when there are inclined surfaces on both sides of the workpiece.

[0006] Preferably, the rear surface of the workbench is fixedly connected to a U-shaped plate, the front surface of the cross plate of the U-shaped plate is fixedly connected to a hydraulic telescopic rod, the upper surface of the workbench is fixedly connected to a positioning block, the upper surface of the workbench is fixedly connected to a second mounting plate, and the rear surface of the second mounting plate is provided with a through groove extending from its front surface.
[0007] Preferably, the front end of the hydraulic telescopic rod extends out of the front surface of the second mounting plate through the through slot, and the front end of the hydraulic telescopic rod is fixedly connected to a push plate.
[0008] Preferably, a motor is arranged at the rear side of the workbench, a second fixing sleeve is sleeved on the outer surface of the motor, and a front side surface of the second fixing sleeve is fixedly connected to the rear side surface of the workbench.
[0009] Preferably, the output end of the motor is fixedly connected to a second worm, the front surface of the workbench is fixedly connected to a protection box, the interior of the protection box is configured to be hollow, and the upper surface of the protection box is provided with a sliding groove extending into the interior thereof.
[0010] Preferably, the front end of the second worm rotates and penetrates into the interior of the protection box, the front and rear side surfaces of the two displacement plates are respectively fixedly connected with threaded sleeves, and the rear side surface of the workbench is fixedly connected with two fixing plates.
[0011] Preferably, one side surface of the two fixing plates that is adjacent to each other is rotatably connected with a bidirectional threaded rod, and the inner wall of the protection box is also rotatably connected with a bidirectional threaded rod.
[0012] Preferably, the front and rear four threaded sleeves are respectively threadedly sleeved on two opposite thread sections of the two bidirectional threaded rods, the outer surfaces of the two bidirectional threaded rods are sleeved with second worm gears, and the two second worm gears are meshingly connected with the second worm gears.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] (1) The CNC blanking machine uses a fixed-point delivery device. When the left and right sides of the plate-like workpiece to be processed are inclined, the worm gear can be driven to rotate by rotating the worm. After the worm gear rotates, it synchronously drives the rotating rod to rotate. After the rotating rod rotates, it synchronously drives the connecting sleeve to rotate. After the connecting sleeve rotates, it synchronously drives the clamping plate to rotate. After the clamping plate is rotated, it is inclined, thereby increasing the contact area with the inclined surface of the plate when clamping and fixing. At the same time, the existence of the roller can reduce friction when positioning the plate front and back. Through the above structure, when the left and right sides of the plate are inclined, the tiltable clamping plate can be used to increase the contact area during clamping, thereby reducing the possibility of damage to the plate due to the small contact area.
[0015] (2) The CNC blanking machine uses a fixed-point delivery device, which uses a motor to drive the second worm to rotate. After the second worm rotates, it synchronously drives the two second worm wheels to rotate. After the two second worm wheels rotate, they synchronously drive the two bidirectional threaded rods to rotate. Since a single displacement plate is indirectly connected to the two bidirectional threaded rods, the movement trajectory of the displacement plate is limited. Therefore, when the bidirectional threaded rod rotates, it will synchronously drive the two displacement plates to move in opposite directions. Through the above structure, the plate can be positioned in the middle part of the workbench during clamping, which is convenient for subsequent processing. At the same time, the protective box can also be used to prevent workers from accidentally contacting the rotating parts on the front side, thereby ensuring the safety of the workers.
