Description

Technical Field

[0001] The utility model relates to the technical field of CNC, in particular to a clamping fixture for CNC four-side rolling processing. Background Art

[0002] Generally, CNC machining (CNC milling machine) refers to computer digital controlled precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. The feed route of CNC machining (CNC milling machine) refers to the path that the turning tool moves from the tool setting point (or the fixed origin of the machine tool) until it returns to the point and ends the machining program, including the cutting path and the non-cutting empty travel path such as tool cutting in and out. The feed route of fine machining is basically carried out in sequence along the contour of the part. The application of CNC machining for mold manufacturing can greatly improve the machining accuracy, reduce manual operation, improve machining efficiency, and shorten the mold manufacturing cycle.

[0003] For example, the Chinese patent with application number "CN202122713646.2", its name is: "A CNC four-sided processing auxiliary clamping fixture", including a base, a rotating shaft, a push rod and a limit rod, the top of the base is fixedly connected to a motor for driving the rotating shaft to rotate vertically, and the outer wall of the rotating shaft is embedded with a first movable rod for driving the push rod to move horizontally, so that the movement of the first movable rod drives the push rod to slide horizontally along the inner wall of the limit rod, and the push rod is fixedly connected to an movable clamping block at one end away from the first movable rod, and by providing a movable clamping block, the material to be processed is placed on the side wall of the fixed clamping block, so that the motor works, drives the rotating shaft to rotate vertically, and at the same time drives the first movable rod to move, and the push rod is driven to slide along the inner wall of the limit rod through the movement of the first movable rod, so that the movable clamping block slides along the outer wall of the first connecting rod, and the processed material is clamped by the movable clamping block and the fixed clamping block, thereby achieving the purpose of clamping the processed material.

[0004] During the use of the device, the material to be processed is clamped by a movable clamp and a fixed clamp, but the device can only clamp the two sides of the material to be processed. The workpiece may swing during the processing, which will affect the processing accuracy. Secondly, when the workpiece is processed, flying debris will be generated, and the collection device alone cannot completely collect the debris. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a clamping fixture for CNC tumbling four-sided processing, which is convenient for clamping the four sides of the workpiece by setting a sliding block, a fixed block and a limit device, so that the workpiece can remain stable during the processing and the processing accuracy of the workpiece is improved. A splash-proof shell, a feed chute and a collection box are provided to facilitate the collection of debris generated by the workpiece processing to avoid affecting the processing effect of the workpiece.

[0006] The utility model also provides the above-mentioned clamping fixture for CNC rolling four-sided processing, comprising: a workbench, two slide slots are arranged above the workbench, and the ends of the two slide slots that are away from each other are fixedly connected with a connecting block, one end of the two connecting blocks are fixedly connected with a motor, the output end of the motor is fixedly connected with a screw rod, the outer side surface of the screw rod is sleeved with a sliding block, the top of the sliding block is fixedly connected with a fixed block, the front and rear upper ends of the workbench are fixedly connected with a connecting plate, the opposite sides of the connecting plate are provided with a limit device for fixing the workpiece, the top of the workbench is fixedly connected with a splashproof shell, a material discharge chute is arranged above the workbench and inside the splashproof shell, a supporting device for supporting the workpiece is arranged on the material discharge chute, and a trough body is arranged on the front side of the workbench, and a collection box is slidably connected to the trough body. By setting up sliding blocks, fixed blocks and limit devices, it is convenient to clamp the four sides of the workpiece, so that the workpiece remains stable during the processing and the processing accuracy of the workpiece is improved. The splashproof shell, feed chute and collection box are set to collect the debris generated by the workpiece processing to avoid affecting the processing effect of the workpiece.

[0007] According to the clamping fixture for CNC tumbling four-side processing, the limiting device includes an electric push rod fixedly connected to one side of the connecting plate, and the end of the electric push rod away from the connecting plate is fixedly connected to the limiting block. The electric push rod drives the limiting block to clamp the front and rear sides of the workpiece.

[0008] According to the clamping fixture for CNC tumbling four-side processing, the inner sides of the limit block and the fixed block are fixedly connected with protective pads, and the protective pads are made of rubber. The protective pads prevent the limit block and the fixed block from damaging the workpiece surface.

The through holes prevent the splash-proof shell from colliding with the fixing block and the limit block.

[0013] According to the clamping fixture for CNC rolling four-side processing, a controller is fixedly connected to one side of the workbench, and the output end of the controller is electrically connected to the motor and the electric push rod. The controller is convenient for staff to operate and control.

A connecting plate 8 is fixedly connected to the upper ends of the front and rear sides of the table 1, and a limiting device 9 for fixing the workpiece is provided on the opposite side of the connecting plate 8. A splash-proof shell 10 is fixedly connected to the top of the workbench 1, and the splash-proof shell 10 can avoid the splashing of debris to the greatest extent. A feed chute 11 is provided above the workbench 1 and inside the splash-proof shell 10, and the debris inside the splash-proof shell 10 on the surface of the workbench 1 is allowed to fall through the feed chute 11. A supporting device 12 for supporting the workpiece is provided on the feed chute 11, and a trough body 13 is provided on the front side of the workbench 1, and a collecting box 14 is slidably connected to the trough body 13, and the debris generated by the processing is collected through the collecting box 14.

[0024] The limiting device 9 includes an electric push rod 901 fixedly connected to one side of the connecting plate 8, and one end of the electric push rod 901 away from the connecting plate 8 is fixedly connected to a limiting block 902. The electric push rod 901 outputs the limiting block 902 to clamp the front and rear sides of the workpiece.

[0025] The supporting device 12 includes a supporting frame 121 fixedly connected to the inner wall of the material discharge chute 11, three interconnected connecting rods 122 are fixedly connected above the supporting frame 121, and a placing table 123 is fixedly connected above the three connecting rods 122, so that the bottom of the workpiece can be supported by the placing table 123.

[0026] Working principle: When using for the first time, place the workpiece to be processed on the placement table 123, and then start the motor 4 to output the screw rod 5 to drive the sliding block 6 to slide inside the slide groove 2. The two sliding blocks 6 slide in opposite directions to drive the fixed block 7 to limit and clamp the left and right sides of the workpiece. At the same time, the electric push rod 901 outputs the limit block 902 to clamp the front and back sides of the workpiece. The four-sided clamping prevents the workpiece from being displaced during processing. Secondly, flying debris will be generated during the processing of the workpiece. The splash-proof shell 10 can effectively prevent the flying debris. At the same time, the debris on the surface of the workbench 1 and in the splash-proof shell 10 falls into the collection box 14 through the discharge chute 11 for collection, so as to prevent the residual debris from affecting the processing of the workpiece.
