Description

Technical Field

[0001] The present application relates to the technical field of tool detection, and in particular to a precise tool setting device for a CNC machine tool. Background Art

[0002] The laser tool setting instrument uses laser light through a transmitter and a receiver to set the tool. It can be installed on the workbench of the gauge machine or on both sides of the workbench so that the laser beam passes through the entire working area. It can be used for high-speed, high-precision tool setting and tool breakage detection. When the tool passes through the laser beam, the light intensity at the receiver decreases, sending a signal to the controller to record the current machine position and derive the tool size from it.

When the tool on the machine tool is to be set and detected, the laser tool setting instrument body 1 can be placed on the machine tool platform and under the tool. By controlling the machine tool, the tool can be moved down, and the tool will move at a uniform speed when it moves down. Rotate, when the tool moves down, the operation of the cleaning component 4 allows the internal components of the cleaning component 4 to clean the tool, and then clean the iron filings adhered to the tool to prevent the iron filings from adhering to the tool and affecting the accuracy of tool setting detection. After cleaning, the tool can be moved down to the inner side of the laser tool setting instrument body 1, and the infrared irradiation and reception of the infrared transmitter 2 and the infrared receiver 7 can be used to collect the data of the tool, and the detection data can be presented through the touch screen controller 3 to facilitate people to view the detection results. In addition, when the iron filings are cleaned, the electromagnet 5 can be used to absorb the iron filings brushed off. When the iron filings on the electromagnet 5 are processed, they can be moved above the receiving box 6 and the electromagnet 5 can be closed to make the adsorbed iron filings fall into the receiving box 6, so as to collect and process the iron filings to prevent the iron filings from splashing and polluting the surrounding environment.

[0036] Reference Figure 2 A slide groove 11 is provided on both sides of the inner side of the main body 1 of the laser tool setting instrument. An electric push rod 12 is fixedly connected to one side of the inner side of the slide groove 11. A slider 13 is fixedly connected to one end of the electric push rod 12. The two sliders 13 are respectively fixedly connected to the infrared transmitter 2 and the infrared receiver 7. When infrared detection is performed on the tool, the slider 13 can be driven by the synchronous operation of the electric push rod 12, so that the slider 13 slides inside the slide groove 11, thereby driving the infrared transmitter 2 and the infrared receiver 7 to move synchronously, and then the tool is detected.

When the brush cleaning member 46 is damaged after long-term use and needs to be replaced, the screw can be manually rotated to remove the brush.

[0040] Working principle: When the tool on the machine tool is to be checked, the laser tool setting instrument body 1 can be placed on the machine tool platform and under the tool.

When the tool moves down, the servo motor 42 can drive the bidirectional threaded rod 43 to rotate. The rotating bidirectional threaded rod 43 can drive the two drive plates 45, thereby driving the two drive plates 45 to approach each other, thereby driving the two cleaning brushes 46 to approach each other. The cleaning brushes 46 can brush away the iron filings adhering to the tool to prevent the iron filings from adhering to the tool and affecting the tool checking. The accuracy of measurement can be improved. After cleaning, the tool can be moved down to the inner side of the laser tool setting instrument body 1. The data of the tool can be collected through the infrared irradiation and reception of the infrared transmitter 2 and the infrared receiver 7, and the detection data can be presented through the touch screen controller 3 to facilitate people to view the detection results. In addition, when cleaning iron filings, the iron filings brushed off can be adsorbed by the electromagnet 5. When the iron filings on the electromagnet 5 are processed, they can be moved to the top of the receiving box 6 and the electromagnet 5 can be closed to make the adsorbed iron filings fall into the receiving box 6, so as to collect and process the iron filings to prevent the iron filings from splashing and polluting the surrounding environment.
