Problems solved by technology

[0002] When traditional CNC manufactures a workpiece that needs to be fully finished, it is usually glued or tightened with screws on the bottom and processed on both sides of the vise. These methods are time-consuming and labor-intensive. Every time a workpiece is replaced, it takes Re-calibration and re-edge finding. If a workpiece needs to be processed several times, it needs to be re-calibrated and edge-finding at each station, which wastes a lot of manpower and time. In the traditional processing of plate-shaped parts, rough machining is performed first, and then dismantling After removing the stress, finish machining. If the precision requirements are high or complex, it needs to be processed several times. Repeated calibration and edge finding will waste a lot of manpower and time, and also increase the risk of human error.

Embodiment 1

[0020] refer to Figure 1 to Figure 4 The shown general-purpose CNC vacuum suction clamping workbench includes a workbench 1, a workpiece positioning assembly 2 and a workpiece pressing assembly. The workbench 1 includes an upper template 1a and a lower template 1b that fit together. The upper template 1a is provided with several vacuum via holes 1a1 distributed in a matrix, the workpiece positioning assembly 2 includes several positioning pins 2a for limiting the workpiece 5, and the workpiece pressing assembly includes several A pressure block 3 that presses the workpiece 5, the worktable 1 saves the time required for traditional workpiece 5 calibration and edge finding through the rapid positioning of the workpiece 5 positioning pin, and the vacuum suction can save the traditional glue or lock on the workpiece 5 Screw link.

[0021] The upper template 1a is a rectangular structure, and all the positioning pins 2a are arranged at intervals along the midline of the upper tem...

Embodiment 2

[0026] The clamping process of the above-mentioned universal CNC vacuum suction clamping workbench includes the following steps: firstly, the workpiece 5 is placed on the upper template 1a of the workbench 1, and the positioning pin 2a of the workpiece positioning assembly 2 limits the workpiece 5, and then Several pressing blocks 3 of the workpiece pressing assembly press the workpiece 5 to compress the workpiece 5, and finally, there are vacuum via holes 1a1 distributed in a matrix on the upper template 1a to vacuum absorb the workpiece 5 to realize quick clamping.

Abstract

The invention relates to the technical field of precision machining, in particular to a universal CNC vacuum-suction clamping workbench. The universal CNC vacuum-suction clamping workbench comprises aworkbench body, a workpiece positioning assembly and a workpiece pressing assembly. The workbench body comprises an upper template and a lower template which are attached together. A plurality of vacuum holes which are distributed in a matrix mode are formed in the upper template. The workpiece positioning assembly comprises a plurality of positioning pins used for limiting a workpiece. The workpiece pressing assembly comprises a plurality of pressing blocks used for pressing the workpiece. According to the universal CNC vacuum-suction clamping workbench, through rapid positioning by the workpiece positioning pins, time for calibration and edge searching of the workpiece is not needed; and through vacuum suction, the traditional link of coating the workpiece with glue or locking the workpiece with screws can be omitted, and thus, clamping is rapider; particularly for workpieces needing to be machined repeatedly, the efficiency is improved more remarkably, and time is saved, and the efficiency is improved; and the clamping process is simple and reliable, and the design is ingenious.
