Abstract

Technical Field
[0001] The utility model relates to the technical field of tool swing detection, in particular to an automatic precision tool swing detector. Background Art
[0002] Tool runout refers to the deviation between the tool's operating diameter and its nominal diameter during tool motion, caused by various factors, such as the machine spindle or tool itself. A common method for measuring tool runout is to use a tool runout gauge to measure the diameter of the rotating tool. The difference in the gauge readings is the runout value. Knowing the runout value allows program modifications or adjustments to tool setup to achieve precise machining according to workpiece data.
[0003] The existing CNC tool machine tool swing detection device is to place the tool swing detector near the CNC after the tool is hung on the CNC machine. The detection table of the tool swing detector is close to the tool, and the protrusion of the detection table contacts the tool. After driving the CNC spindle to rotate, the pointer of the detection table begins to swing. The difference in the calibration table reading is the swing number, thereby achieving the effect of detecting tool swing.
[0004] The drawback of this tool swing detection method is that the tool swing detection takes up the operation time of the machine, which consumes a long time and delays the working efficiency of the machine, thereby reducing the output value of the machine.
[0005] Based on this, the utility model designs an automatic precision tool swing detector to solve the above problems. Utility Model Content

[0029] The following is combined with Figure 1-6 This application is described in further detail.

In this embodiment, the rotating rod 8 is driven to rotate by a motor 9; the support cylinder 3 is coaxially threadedly connected to the rotating rod 8, the support cylinder 3 is in a frustum shape, a fixing plate 10 is fixedly provided on the support base 5, a bearing 11 is rotatably provided on the fixing plate 10, the support cylinder 3 is plugged into the inner ring of the bearing 11, so that the support cylinder 3 can rotate on the installation box 1;
[0031] Reference Figures 1-6 , a placing rod 12 is provided on the fixing plate 10, a mounting block 13 is provided on the placing rod 12, a moving block 14 is slidably provided on the mounting block 13, a fixing component for fixing the moving block 14 is provided on the mounting block 13, and the tool swing detection table 4 is fixedly set on the moving block 14; before the detection, the tool 2 is first placed vertically in the supporting cylinder 3, and the inner wall of the supporting cylinder 3 supports the tool 2, and the moving block 14 is adjusted to move the tool swing detection table 4 toward the side of the tool 2 until the detection head of the tool swing detection table 4 contacts the tool 2, The moving block 14 is fixed by a fixing component, and then the motor 9 is driven to rotate the rotating rod 8, which drives the supporting cylinder 3 to rotate, thereby driving the tool 2 to rotate. At this time, the tool swing detection meter 4 detects the tool 2. When the pointer deviation value of the tool swing detection meter 4 is not within the specified range, it indicates that the tool 2 has a defect. The tool 2 is detected in advance by the tool swing detection device, and there is no need to turn on the CNC for detection. The process is fast and simple. The tool 2 is detected in advance, thereby reducing CNC shutdown and achieving the effect of improving work efficiency.
[0032] Reference Figures 1-6 A fixing block is fixed on the groove wall of the mounting groove 6, and a mounting rod 15 is fixedly arranged on the fixing block at an angle. A supporting wheel 16 is rotatably arranged on the mounting rod 15, and two supporting wheels 16 are arranged on the upper and lower parts of the mounting rod 15, and the upper and lower supporting wheels 16 respectively abut against the supporting tube 3. A plurality of mounting rods 15 are provided in the mounting groove 6. In this embodiment, three mounting rods 15 are equidistantly arranged in the mounting groove 6, and the angle between the center points of the three mounting rods 15 is 120 degrees; when the supporting tube 3 rotates, the six supporting wheels 16 respectively support the supporting tube 3, reduce the swing of the supporting tube 3, and improve the accuracy of the detection.

[0033] Reference Figures 1-6When it is necessary to replace a different type of support tube 3, the support tube 3 is removed from the rotating rod 8 and the required support tube 3 is replaced to facilitate the detection of tools 2 of different sizes; a debris groove 17 is provided on the rotating rod 8, and the debris groove 17 is located in the support tube 3. The debris groove 17 is located below the tool 2. The debris generated during the detection falls down into the debris groove 17 for collection, reducing the impact of residual debris accumulation on the placement of the tool 2.
[0034] The implementation principle of this embodiment is: before detection, the tool 2 is placed in the support cylinder 3, and the moving block 14 is pushed at the same time to allow the tool swing detection head to contact the tool 2. During detection, the motor 9 is driven to drive the rotating rod 8 to rotate, thereby driving the support cylinder 3 to rotate. At this time, the support wheel 16 supports the support cylinder 3 to prevent the support cylinder 3 from swinging. The support cylinder 3 stably drives the tool 2 to rotate. At this time, the pointer on the tool swing detection table 4 swings. When the pointer swings beyond the specified range, it indicates that there is a defect on the tool 2. The tool 2 is detected in advance by the tool swing detection device, and there is no need to turn on the CNC for detection. The process is fast and simple. The tool 2 is detected in advance, thereby reducing CNC shutdown and achieving the effect of improving work efficiency.
