Description

Technical Field

[0001] The utility model belongs to the technical field of cutting, and in particular relates to a cutting device with high efficiency and precise positioning. Background Art

[0002] CNC cutting device is a kind of efficient and precise processing equipment that uses computer control system to control cutting tool to cut materials. Although CNC cutting device has many advantages, some existing devices still have some problems in actual application. One of the main problems is that when the cutting tool is feeding, the processing computer does not know the actual thickness of the material being processed. Since the processing computer cannot sense the material thickness in real time, the cutting tool may not make enough prediction when entering the material, resulting in the tool entering the material completely before the bottom of the material is completely cut through. This will cause the tool to run empty for a long time at the bottom of the material, wasting time and cutting force. Since the thickness of the material cannot be accurately known, the processing computer often cannot accurately calculate the quick entry point of the tool, which will affect the cutting process and the cutting effect is not ideal. Utility Model Content

[0003] In order to overcome the existing CNC cutting device, because the processing computer does not know the thickness of the material being processed when the cutting tool is fed, the tool is prone to long-term idling during feeding, cannot accurately calculate the rapid entry point, and increases the problem of tool wear.

[0004] The technical solution of the utility model is: a cutting device with high efficiency and precise positioning, including a gear box transmission assembly and a workpiece feeding assembly; a workpiece feeding assembly is arranged below the gear box transmission assembly; the gear box transmission assembly includes a spindle box, a cutting disc, a transmission shaft, a height adjustment cylinder, a laser height measurement sensor, and an ultrasonic thickness sensor; a cutting disc is arranged at the front end of the spindle box, and the cutting disc is transmission-connected to the output end of the spindle box.

[0005] Preferably, a laser height measurement sensor is used to calculate the spatial position of the spindle box in real time, effectively improving the accuracy of the feed entry point of the cutting blade when processing the workpiece. At the same time, an ultrasonic thickness sensor is used to calculate the thickness of the workpiece under the cutting blade, thereby effectively improving the cutting efficiency and preventing the tool from running empty and wearing during feeding, thereby improving the accuracy of automated processing, and solving the problem of existing CNC cutting devices, because the processing computer does not know the thickness of the material being processed when the cutting tool is fed, resulting in long-term empty feeding of the tool, inability to accurately calculate the rapid entry point, and increased tool wear.

[0006] Preferably, a transmission shaft is provided at the rear end of the spindle box, and the transmission shaft is transmission-connected to the input end of the spindle box.

[0007] Preferably, a height-adjusting cylinder is provided on one side of the spindle box, and the outer shell of the height-adjusting cylinder is fixedly connected to the outer shell of the spindle box, and the output end of the height-adjusting cylinder is pneumatically lifted and driven by the external bracket below. The height-adjusting cylinder drives the spindle box as a whole to perform lifting operations, thereby effectively improving the speed and height adjustment sensitivity of the cutting blade during feed and retract, and preventing the cutting blade tool from wearing due to slow feed and retract.

[0008] Preferably, laser height measuring sensors are provided on both sides of the spindle box, and the laser height measuring sensors are fixedly connected to the outer shell of the spindle box, and the outer side of the detection angle of the laser height measuring sensor is tilted downward. The laser height measuring sensor is used to calculate the spatial position of the spindle box in real time, effectively improving the feed entry point accuracy of the cutting disc when processing the workpiece.

[0009] Preferably, the workpiece feeding assembly includes a worktable and a workpiece; the worktable is arranged below the gearbox transmission assembly; the workpiece is arranged at the upper end of the worktable, and the workpiece is fixedly connected to the worktable.

[0010] Preferably, ultrasonic thickness sensors are provided on the top and both sides of the cutting disc, and the ultrasonic thickness sensors are fixedly connected to the outer shell of the spindle box. The ultrasonic thickness sensors cooperate to calculate the thickness of the workpiece under the cutting disc, thereby effectively improving the cutting efficiency, preventing the tool from running empty and wearing, and improving the accuracy of automated processing.

[0011] Beneficial effects of the utility model:

[0012] 1. The existing CNC cutting device, because the processing computer does not know the thickness of the material being processed when the cutting tool is fed, it is easy to run empty for a long time when the cutting tool is fed, and the rapid entry point cannot be accurately calculated, which increases the wear of the cutting tool. The laser height measurement sensor is used to calculate the spatial position of the spindle box in real time, effectively improving the accuracy of the feeding entry point of the cutting disc when processing the workpiece, and at the same time, the ultrasonic thickness sensor is used to calculate the thickness of the workpiece under the cutting disc, thereby effectively improving the cutting efficiency, preventing the tool from running empty and wearing, and improving the accuracy of automated processing; This solves the problem that the existing CNC cutting device, because the processing computer does not know the thickness of the material being processed when the cutting tool is fed, causes the tool to run empty for a long time when the cutting tool is fed, cannot accurately calculate the rapid entry point, and increases the wear of the cutting tool;

[0013] 2. Through the setting of the height adjustment cylinder, the height adjustment cylinder drives the spindle box to perform lifting operations as a whole, effectively improving the speed and height adjustment sensitivity of the cutting disc during feed and retract, and preventing the cutting disc tool from wearing due to slow feed and retract.
