Description

Technical Field

[0001] The utility model relates to the technical field of numerical control drilling machines, in particular to a clamp for a numerical control drilling machine. Background Art

[0002] The CNC drilling machine fixture is a device used to fix and position the workpiece on the CNC drilling machine. It is characterized by a compact structure, quick and convenient operation, and labor-saving.

[0003] An existing Chinese patent (publication number: CN208428007U) proposes a CNC drilling machine fixture, including a workbench, to which a first fixed plate, a second fixed plate, a third fixed plate and a fourth fixed plate are fixedly connected on the front, right, rear and left sides above the workbench, respectively. A first hydraulic cylinder is installed on the rear side of the first fixed plate, and a second hydraulic cylinder is installed on the left side of the second fixed plate. Limiting holes and open slots are provided on the third and fourth fixed plates. A limiting rod is movably connected inside the limiting hole, and a rack is provided below the open slot.

[0004] The above technical solution relieves the pressure generated by clamping during the clamping process by setting the spring and rubber pad in the clamping mechanism, thereby protecting the object to be processed. The rough adjustment of the horizontal position of the object is achieved by setting the first hydraulic cylinder and the second hydraulic cylinder. The precise horizontal movement and adjustment of the object can be achieved by shaking the handle by setting the worm gear, worm and rack, making the punching position more accurate.

[0005] However, during the drilling process, the downward pressure is too great, which can easily cause damage to both sides of the workpiece. However, the above device does not have a support structure for this. In addition, since debris is generated during the drilling process, if it is not collected in time, it will cause the debris to fall from the hole into the mechanical components below, which can easily cause damage to the mechanical components. Therefore, we proposed a CNC drilling machine fixture. Utility Model Content

[0006] The purpose of the present invention is to provide a CNC drilling machine fixture to solve the problems raised in the above background technology.

[0017] The above technical solution is adopted: by setting a second motor, the first clamping plate can be driven to rotate, thereby driving the workpiece to flip, and the water and debris after cooling the workpiece will flow from the hole into the collection box below.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are:

[0019] 1. In the utility model, a support component is provided to prevent the two sides of the workpiece from being broken due to excessive downward pressure during the drilling process.

By setting a second motor, the first clamping plate can be driven to rotate, thereby driving the workpiece to flip, and the water and debris after the workpiece is cooled can flow from the hole into the collection box below.
