Technical Field

[0001] The utility model relates to the field of numerical control equipment, in particular to a part clamping tool for a numerical control machining machine tool. Background Art

[0002] CNC machine tools are automated machine tools that are controlled by computer digital programs and are capable of high-precision and high-efficiency processing. They control the motion trajectory, speed and processing parameters of the machine tool through programming to achieve the processing of complex shapes and fine structures. The part clamping tool of the CNC machine tool is a device specially designed to fix and support the processed parts. It allows the CNC machine tool to accurately process parts. In CNC processing, the part clamping tool must meet the requirements of high precision and high stability to ensure the accuracy and repeatability of the processing process. In some special processing environments, the surface of the workpiece is often stained with some oil before being clamped. It is relatively difficult to wipe it with a rag. If the oil is not cleaned, the workpiece may slip after being clamped, thus affecting the accuracy of the processing. Utility Model Content

[0003] In order to overcome the problem that during CNC machining, it is sometimes necessary to clean the oil stains on the surface of the workpiece before clamping the workpiece. However, it is relatively time-consuming and ineffective to just wipe the oil stains with a rag, which may cause the workpiece to slip due to residual oil stains after being clamped, thus affecting the machining accuracy.

[0004] The technical solution of the utility model is: a part clamping tool for a CNC machining machine tool, comprising an adjusting component, a cleaning component, a fixing component and a shock-absorbing component; a cleaning component for cleaning dirt from a workpiece is rotatably connected inside the adjusting component; a fixing component for fixing the workpiece is arranged at the rear end of the cleaning component; and a shock-absorbing component for suppressing vibration is installed on the fixing component.

[0005] Preferably, the adjusting component is used to control the angle of the cleaning component, the cleaning component is used to clean the oil stains on the surface of the workpiece, the fixing component is used to fix the workpiece, and the shock absorbing component is used to suppress vibration.

After the workpiece is clamped by the second clamping block, the first hydraulic cylinder retracts, and the motor drives the transmission gear to rotate, thereby rotating the gear ring to change the position of the nozzle and the first clamping block from vertical to horizontal, and then the second hydraulic cylinder pushes the fixed frame forward to move the clamped workpiece to the front end of the device.

[0007] Preferably, the cleaning assembly includes a gear ring, a first receiving groove, a first hydraulic cylinder, a fixed plate, a nozzle, a water pipe connector, a first clamping block, and a curved wiper strip; the upper end of one side of the transmission gear is meshed with a gear ring that rotates in the ring groove; both sides of the inner ring of the gear ring are provided with a first receiving groove; the upper and lower ends of the inner ring of the gear ring are fixedly connected to the first hydraulic cylinder; and the first hydraulic cylinder is fixedly connected to the fixed plate. The liquid outlet device containing the cleaning agent is connected through the water pipe connector, and then the first clamping block is displaced by the first hydraulic cylinder to clamp the rear end of the workpiece, and then the cleaning agent is continuously sprayed onto the surface of the workpiece by the nozzle until the oil stains are dissolved and fall off, and then the workpiece is manually pushed to the rear end, and the liquid at the upper and lower ends of the workpiece is scraped off by the curved wiper strip.

[0008] Preferably, the fixed plates are all fixedly connected with nozzles; one side of the nozzles is connected with a water pipe connector; the rear end of the nozzles is fixedly connected with a first clamping block; and the front end of the nozzles is fixedly connected with a curved wiper strip.

The position of the second clamping block is adjusted by the fourth hydraulic cylinder so that the clamping component can be adapted to workpieces of multiple sizes, and in the process of the first hydraulic cylinder pushing the first clamping block, the third hydraulic cylinder pushes the slide plate and the second clamping block synchronously. When the workpiece is manually pushed to the rear end, the rear end of the workpiece will be displaced between the upper and lower sets of second clamping blocks. When the workpiece completely slides off the first clamping block, the third hydraulic cylinder pushes the slide plate and the second clamping block again to clamp the workpiece.

When the counterweight block 403 moves, the shock absorber 404 absorbs the impact energy between the two counterweight blocks 403 to suppress the resonance peak between the counterweight block 403 and the equipment, thereby suppressing the vibration of the equipment.
