Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC machine tool technology, specifically a novel tool setting structure for CNC machine tools. Background Technology
[0002] A tool setter is a high-precision ON / OFF contact sensor used for positioning cutting tools and nozzles. It is mainly used to measure the size and position of cutting tools on CNC machine tools to ensure machining accuracy and quality. The core components of the tool setter consist of a high-precision switch (probe), a high-hardness, high-wear-resistant cemented carbide tetrahedron (tool setting probe), and a signal transmission interface. The tetrahedron probe is used to contact the tool and transmits force to the high-precision switch through a flexible support rod installed below it. The on / off signal emitted by the switch is transmitted to the CNC system through the signal transmission interface for tool orientation identification, calculation, compensation, and storage.
[0003] Tool setters are usually fixedly installed on the worktable of CNC machine tools. During the machining process, the tool setter occupies worktable space and is prone to damage to the tool. In order to solve the above problems, the inventor proposes a new tool setter structure for CNC machine tools. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example: Figure 1-5 As shown, this utility model provides a novel tool setting structure for CNC machine tools, including a worktable 1, which is a worktable inside the CNC machine tool used to place the workpiece. A mounting plate 2 is rotatably mounted on one side of the worktable 1. A tool setting device 3 is bolted to the mounting plate 2. The tool setting device 3 is a fully automatic contact type tool setting device, which is existing technology. It consists of a high-precision switch (probe), a high-hardness, high-wear-resistant cemented carbide tool setting probe, and a signal transmission interface. During tool setting, the corresponding program is input into the CNC system. The probe of the tool setting device 3 contacts the tool, and the force is transmitted to the high-precision switch through a flexible support rod installed below it. The on / off signal emitted by the switch is transmitted through signal transmission... An interface device transmits data to the CNC system for tool direction recognition, calculation, compensation, and storage to achieve automatic tool setting. A worm gear 11 is fixedly mounted on the rotating shaft of the mounting plate 2. A worm 10 is rotatably mounted on one side of the worktable 1, and the worm 10 meshes with the worm gear 11. A second motor 12 is fixedly mounted on the side of the worktable 1 where the mounting plate 2 is mounted, and the output end of the second motor 12 is fixedly connected to one end of the worm 10. After tool setting is completed, the second motor 12 drives the worm 10 to rotate, the worm 10 drives the worm gear 11 to rotate, and the worm gear 11 drives the mounting plate 2 and the tool setting device 3 to rotate 90 degrees, thereby hiding the tool setting device 3 on one side of the worktable 1. This way, it will not occupy the space of the worktable 1 and will not damage the tool.
[0021] A fixed plate 6 is fixedly installed on one side of the workbench 1 where the mounting plate 2 is installed. A rotating plate 7 is rotatably installed on the fixed plate 6. A brush plate 8 is detachably installed on the rotating plate 7.
[0022] By adopting the above technical solution, when the tool setter 3 is rotated 90 degrees and hidden on one side of the worktable 1, the probe surface of the tool setter 3 comes into contact with the bristles of the brush plate 8, and the rotating plate 7 drives the brush plate 8 to rotate, cleaning the probe surface of the tool setter 3, removing impurities from the probe surface, and preventing the probe from affecting the accuracy of the next use.
[0023] A first motor 9 is fixedly installed on the fixed plate 6, and the output end of the first motor 9 is fixedly connected to the rotating plate 7.
[0024] By adopting the above technical solution, the first motor 9 drives the rotating plate 7 to rotate.
[0025] Two mirror-distributed lifting plates 13 are slidably installed inside the rotating plate 7, and the surfaces of the two lifting plates 13 that are close to each other are fixedly installed with locking blocks 14.
[0026] By adopting the above technical solution, the lifting plate 13 can drive the two locking blocks 14 to move away from or closer to each other.
[0027] A bidirectional lead screw 15 is rotatably installed inside the rotating plate 7, and the bidirectional lead screw 15 is threaded into one end of the two lifting plates 13. A knob 16 is fixedly installed at the top of the bidirectional lead screw 15.
[0028] By adopting the above technical solution, the knob 16 drives the bidirectional lead screw 15 to rotate, and the bidirectional lead screw 15 drives the two lifting plates 13 to move away from each other or closer to each other.
[0029] Both the upper and lower ends of the brush plate 8 are provided with slots 17, and the card block 14 can be locked in the corresponding slot 17.
[0030] By adopting the above technical solution, the locking block 14 on the lifting plate 13 can be inserted into the locking slot 17 on the brush plate 8 to fix the brush plate 8.
[0031] A fixing rod 4 is fixedly installed on one side of the workbench 1 where the mounting plate 2 is installed, and a stop block 5 is fixedly installed on the fixing rod 4.
[0032] By adopting the above technical solution, the stop block 5 can limit the mounting plate 2 and prevent the mounting plate 2 from rotating excessively.
[0033] Working principle: Tool setting device 3 can be used for tool setting. After tool setting is completed, the second motor 12 drives the worm gear 10 to rotate, the worm gear 10 drives the worm wheel 11 to rotate, and the worm wheel 11 drives the mounting plate 2 and the tool setting device 3 to rotate 90 degrees, so that the tool setting device 3 can be hidden and stored on one side of the worktable 1. This way, it will not occupy the space of the worktable 1 and will not damage the tool.
[0034] After the tool setter 3 is rotated 90 degrees and hidden in the side of the workbench 1, the probe surface of the tool setter 3 comes into contact with the bristles of the brush plate 8, and the first motor 9 drives the rotating plate 7 to rotate. The rotating plate 7 drives the brush plate 8 to rotate, cleaning the probe surface of the tool setter 3 and removing impurities from the probe surface to prevent the accuracy of the probe from being affected during the next use.
[0035] When it is necessary to replace the brush plate 8, the knob 16 is used to drive the bidirectional lead screw 15 to rotate. The bidirectional lead screw 15 drives the two lifting plates 13 to move away from each other. The lifting plates 13 drive the locking block 14 to disengage from the locking groove 17 on the brush plate 8, thereby releasing the limit on the brush plate 8 and realizing the purpose of facilitating the replacement of the brush plate 8.
[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
