Technical Field

[0001] The invention relates to the technical field of plastic processing, and in particular to a five-axis plastic precision processing machine tool device. Background Art

[0002] The five-axis machine tool uses the linkage of the three linear axes X, Y, and Z and the two rotary axes A, B (or C) to enable the machine tool to complete high-precision machining of multiple surfaces or even complex curved surfaces of a part in one clamping. This multi-axis linkage technology effectively improves the machining accuracy and efficiency of the parts, and can process various complex parts at the same time, avoiding tool interference, overcutting and undercutting.

[0003] In the process of using five-axis machine tools to process special plastic products (plastics with high precision requirements and high costs, such as liquid crystal polymer (LCP) products, polycarbonate (PC) products, etc.), since these plastic products themselves have high utilization, cost and precision requirements, during the five-axis machine tool processing process, the cut block plastic and debris plastic directly fall into the machine tool and are not easy to collect, resulting in difficulty and low efficiency in recycling and reusing the block plastic, and the debris plastic directly enters the machine tool, causing pollution.

[0014] The present invention provides a chip collection method for a five-axis plastic precision machining machine tool device, which is applied to the above-mentioned five-axis plastic precision machining machine tool device and comprises the following steps:

[0015] S1: The plastic products added by the fixture on the top of the workbench are processed by the machine tool body and the block plastic and debris plastic produced fall into the receiving frame, and the block plastic is received by the chip removal net, while the debris plastic passes through the chip removal net and falls onto the chip collecting plate, so that the block plastic and debris plastic are collected in layers, and the block plastic is recycled and the debris plastic is processed;

[0016] S2: During the collection process, the fixed rod and the three rotating columns are driven to rotate around the workbench through the rotation of the rack 2, and the three gears 1 are driven to move and rotate along the inner surface of the rack 1, and the rotating column is also driven to rotate with the axis of the gear 1 as the rotation point, that is, the rotating column rotates, so as to drive the chip collecting plate, the chip removal net, and the material receiving frame to rotate around the workbench, so that the chip removal net evenly collects the fallen debris and block plastics, and drives the spreading plate to rotate, flattening the block plastics on the chip removal net, so that the chip removal net collects more block plastics;

During the rotation of the rotating column, the spreading plate and the filter rotating plate are driven to rotate in the rotating trough. The nearby block plastic is flattened by the rotation of the spreading plate, so that the block plastic falling on the chip removal net is gradually flattened inside the upper end of the collecting frame, which can collect more fallen block plastics. The rotation of the spreading plate stirs the block plastics and debris plastics on the chip removal net, accelerating the debris plastics to pass through the chip removal net and be collected in layers with the block plastics.

[0037] The present invention provides a chip collection method for a five-axis plastic precision machining machine tool device, which is applied to the above-mentioned five-axis plastic precision machining machine tool device and comprises the following steps:

[0038] S1: The plastic products added by the fixture on the top of the workbench are processed by the machine tool body and the block plastic and debris plastic produced fall into the receiving frame, and the block plastic is received by the chip removal net, while the debris plastic passes through the chip removal net and falls onto the chip collecting plate, so that the block plastic and debris plastic are collected in layers, and the block plastic is recycled and the debris plastic is processed;

[0039] S2: During the collection process, the fixed rod and the three rotating columns are driven to rotate around the workbench through the rotation of the rack 2, and the three gears 1 are driven to move and rotate along the inner surface of the rack 1, and the rotating column is also driven to rotate with the axis of the gear 1 as the rotation point, that is, the rotating column rotates, so as to drive the chip collecting plate, the chip removal net, and the material receiving frame to rotate around the workbench, so that the chip removal net evenly collects the fallen debris and block plastics, and drives the spreading plate to rotate, flattening the block plastics on the chip removal net, so that the chip removal net collects more block plastics;

[0040] S3: When the plastic product processing is completed, the block plastic on the chip discharge net is manually collected for recycling and reuse, and when the discharge net is opened, the broken plastic on the chip collecting plate is discharged for recycling.

[0041] Working principle: When the plastic product is clamped on the upper end of the workbench 23 and processed by the five-axis machine tool body 1, the block plastic falls onto the chip removal net 32 ​​and is surrounded by the upper end of the receiving frame 31, and the debris plastic falls through the chip removal net 32 ​​and falls to the chip collecting plate 35 and is collected at the bottom of the receiving frame 31. In this way, the processed block plastic and debris plastic are collected in layers in the receiving frame 31, preventing the debris plastic from polluting the inside of the machine tool body 1, and the block plastic can be collected for recycling. During the collection process, the waterproof motor 59 is powered on to drive the gear 2 55 to rotate at a low speed, so that the rack 2 56 rotates, driving the three rotating columns 53 and the gear 1 52 to rotate around the workbench 23, and the gear 1 52 is driven by the rack 1 51. The rotation causes the rotating column 53 to further rotate with its own axis as the rotation point, driving the receiving frame 31, the chip removal net 32, and the chip collecting plate 35 to rotate around the workbench 23, so that the chip removal net 32 ​​and the chip collecting plate 35 respectively and evenly catch the block plastic and debris plastic falling from the surroundings of the plastic product processing. During the rotation of the rotating column 53, the spreading plate 57 and the filter rotating plate 33 are driven to rotate in the rotating groove 36. The spreading plate 57 rotates to flatten the nearby block plastics, so that the block plastics falling on the chip removal net 32 ​​are gradually flattened inside the upper end of the collecting frame, so that more fallen block plastics can be collected. In addition, the rotation of the spreading plate 57 stirs the block plastics and debris plastics on the chip removal net 32, accelerating the debris plastics to pass through the chip removal net 32 ​​and be collected in layers with the block plastics.
