Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC machine tool workpiece measurement technology, specifically a CNC machine tool workpiece measurement module. Background Technology
[0002] CNC machine tools are high-precision and high-efficiency machining equipment that play an indispensable role in modern manufacturing. When CNC machine tools process workpieces, a measurement module is needed to measure them to make the processing data more accurate.
[0003] In existing technologies, general measurement modules require periodic cleaning of the probes or cleaning based on abnormal test data. They cannot automatically detect whether dust has adhered to the probes, affecting the test data. Furthermore, the probes lack protective limit devices during testing, which may cause them to deviate and thus affect the test results. Utility Model Content
[0004] The purpose of this invention is to provide a CNC machine tool workpiece measurement module to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a CNC machine tool workpiece measurement module, comprising a tool holder and an infrared probe. The bottom of the tool holder is provided with the infrared probe, and the bottom of the infrared probe is provided with a connecting seat. Temperature sensors are provided at the middle positions on both sides of the connecting seat, and optical sensors are provided on both sides of the bottom of the connecting seat. A probe is provided at the middle position of the bottom of the connecting seat, and limiting blocks are provided at the bottom of the connecting seat on both sides of the probe. Infrared sensors are provided at both ends of the bottom of the limiting blocks, and alarms are provided on the outer sides of the limiting blocks corresponding to the positions of the infrared sensors. The alarm is electrically connected to the infrared sensor. Both ends of the limiting block have threaded holes, and corresponding threaded holes at both ends of the limiting block are connected to screws via threads. The outer side of the limiting block has grooves corresponding to the screw positions, and the screws within these grooves are connected to nuts via threads. This allows the infrared sensor to detect whether dust adheres to the probe before it measures the workpiece, and to issue an alarm and initiate cleaning as needed. This prevents excessive dust accumulation from affecting the detection data. Furthermore, during use, the probe can be limited and fixed to prevent displacement that could affect the detection results.
[0006] Preferably, the inner side of each limiting block is arc-shaped, and the arc shape of the inner side of each limiting block is in contact with the outer side of the probe, and the inner side of each limiting block is uniformly provided with arc-shaped grooves.
[0007] Preferably, springs are evenly arranged in the arc-shaped grooves, and the other end of each spring is provided with an arc-shaped pad corresponding to the arc-shaped groove, so that the arc-shaped pad contacts the probe under the action of the spring to buffer it, which can prevent excessive extrusion pressure from causing wear to the probe.
[0008] Preferably, the bottom of the connecting seat corresponding to the limiting block is provided with a sliding groove, and a slider is slidably connected in the sliding groove, and the bottom of the slider is connected to the corresponding limiting block.
[0009] Preferably, the slider is provided with a telescopic shield on the side away from the probe, and the other end of the telescopic shield is connected to the slide groove. When the slider moves the limiting block on the slide groove, it moves the telescopic shield together, which can shield the slide groove and reduce the adhesion of dust and debris.
[0010] Preferably, a fixing bolt is threadedly connected to the middle position of the bottom of the limiting block on the side away from the probe, and the limiting block is connected to the connecting seat through the fixing bolt, so that the fixing bolt fixes the limiting block to the connecting seat and prevents it from shifting.
[0011] Preferably, a connecting block is provided at the middle position of the top of the probe, and the outer side of the connecting block is uniformly provided with external threads.
[0012] Preferably, the connecting block has a connecting groove at the middle position of the bottom of the connecting seat, and the inner side of the connecting groove is uniformly provided with internal threads corresponding to the external threads. The connecting groove is connected to the connecting block by threads, so that the probe is connected to the connecting seat by threads through the connecting block, which facilitates assembly and disassembly.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This CNC machine tool workpiece measurement module uses an infrared sensor to determine the dust concentration based on the intensity of reflected light. When there is dust on the probe, it may affect the intensity or signal of the reflected light, causing abnormal sensor readings. Then, it can transmit alarm information to the alarm device, which can process the information and issue an alarm, reminding the staff to clean the probe. This can prevent excessive dust from adhering to the probe and affecting its detection data. Before use, the probe can be connected to the connecting seat, and then the limiting block can be moved to make it fit with the probe. Then, the screw can be taken and screwed through the corresponding threaded hole, and nuts can be screwed on both ends of the screw to limit and fix it. After the limiting block is connected and fixed, the probe can be limited to prevent it from deviating during use and affecting its detection effect. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0021] Please see Figure 1-5 The present invention provides an embodiment of a CNC machine tool workpiece measurement module, comprising a tool holder 1 and an infrared probe 2. The bottom of the tool holder 1 is provided with the infrared probe 2, and the bottom of the infrared probe 2 is provided with a connecting seat 3. Temperature sensors 4 are provided at the middle positions on both sides of the connecting seat 3, and optical sensors 12 are provided on both sides of the bottom of the connecting seat 3. A probe 5 is provided at the middle position of the bottom of the connecting seat 3, and a limiting block 6 is provided at the bottom of the connecting seat 3 on both sides of the probe 5. Infrared sensors 11 are provided at both ends of the bottom of the limiting block 6, and an alarm 10 is provided on the outer side of the limiting block 6 corresponding to the position of the infrared sensor 11. The alarm 10 is electrically connected to the infrared sensor 11.
[0022] In use, the infrared sensor 11 can determine the dust concentration based on the intensity of reflected light. When there is dust on the probe 5, it may affect the intensity or signal of the reflected light, causing abnormal sensor readings. Then, it can transmit alarm information to the alarm 10, which can process the information and issue an alarm to remind the staff to clean the probe 5. This can prevent excessive dust from adhering to the probe 5 and affecting its detection data. In use, the temperature sensor 4 can sense the temperature information at the workpiece detection point to prevent the temperature from being too high, and the optical sensor 12 can sense the position information of the workpiece. The temperature sensor 4 and the optical sensor 12 can transmit the sensed information to the control system, which can then control its movement. The probe 5 and the infrared probe 2 can then collect and process the data information of the detected workpiece in the data control system.
[0023] The limiting block 6 has threaded holes at both ends, and screw rods 7 are threadedly connected between the corresponding threaded holes at both ends of the limiting block 6. The limiting block 6 has grooves 8 on the outer side corresponding to the screw rods 7, and nuts are threadedly connected to the screw rods 7 in the grooves 8.
[0024] In use, the limiting block 6 can be moved to fit against the probe 5. Then, the screw 7 can be taken and screwed through the corresponding threaded hole. Nuts can be screwed on both ends of the screw 7 to limit and fix it. When screwing, the two ends of the screw 7 can be placed in the groove 8 to protect the two ends of the screw 7 and prevent it from exceeding the limiting block 6, which would cause inconvenience. After the limiting block 6 is connected and fixed, the probe 5 can be limited to prevent it from deviating during use and affecting its detection effect.
[0025] The inner side of the limiting block 6 is arc-shaped, and the arc shape of the inner side of the limiting block 6 is in contact with the outer side of the probe 5. The inner side of the limiting block 6 is uniformly provided with arc-shaped grooves 18, and springs 19 are uniformly provided in the arc-shaped grooves 18. The other end of the springs 19 is provided with arc-shaped pads 9 corresponding to the arc-shaped grooves 18.
[0026] When in use, after the limiting block 6 is in contact with the probe 5, the inner arc-shaped pad 9 can contact it, and the arc-shaped pad 9 can buffer the contact force through the action of the spring 19 to prevent excessive contact pressure from causing wear to the probe 5.
[0027] The bottom of the connecting seat 3 corresponding to the limiting block 6 is provided with a sliding groove 13, and a slider 15 is slidably connected in the sliding groove 13. The bottom of the slider 15 is connected to the corresponding limiting block 6. A telescopic shield 14 is provided on the side of the slider 15 away from the probe 5, and the other end of the telescopic shield 14 is connected to the sliding groove 13.
[0028] In use, the limiting block 6 can be moved on the slide groove 13 by the action of the slider 15 so that it is in contact with the probe 5. At the same time, when it moves, it can drive the telescopic shield 14 to extend and retract to shield the slide groove 13, which can reduce the adhesion of dust and impurities and affect its movement effect.
[0029] A fixing bolt 20 is threadedly connected to the middle position of the bottom of the limiting block 6 on the side away from the probe 5, and the limiting block 6 is connected to the connecting seat 3 through the fixing bolt 20.
[0030] When in use, after the limit blocks 6 are connected by the screw 7, the fixing bolt 20 can be screwed through the limit block 6 and the slider 15 and connected to the connecting seat 3 to prevent the limit block 6 from shifting.
[0031] A connecting block 16 is provided at the middle position of the top of the probe 5, and the outer side of the connecting block 16 is uniformly provided with external threads. The connecting block 16 is provided with a connecting groove 17 at the middle position of the bottom of the connecting seat 3, and the inner side of the connecting groove 17 is uniformly provided with internal threads corresponding to the external threads. The connecting groove 17 is connected to the connecting block 16 through threads.
[0032] In use, the probe 5 is screwed into the connecting groove 17 through the external thread of the connecting block 16, which facilitates its assembly and disassembly.
[0033] In this embodiment, the connecting block 16 at the top of the probe 5 is screwed into the connecting groove 17 for easy assembly and disassembly. Then, the limiting block 6 can be moved to engage with the probe 5. During this movement, the connected slider 15 moves within the slide groove 13, simultaneously causing the telescopic shield 14 to extend and retract, blocking the slide groove 13 and reducing the adhesion of dust and impurities that could affect its movement. The screw 7 can then be screwed through the corresponding threaded hole, and nuts are screwed onto both ends of the screw 7 for positioning and fixing. During screwing, both ends of the screw 7 are positioned within the groove 8, protecting them from exceeding the limiting block 6 and causing inconvenience. During connection, the inner arc-shaped pad 9 contacts the probe 5, and the spring 19 cushions the contact force, preventing excessive pressure that could wear the probe 5. Finally, the fixing bolt 20 can be screwed through the limiting block 6 and the slider 15 to connect with the connecting seat 3, preventing further movement. Block 6 shifts, and once the limiting block 6 is connected and fixed, it can limit the probe 5 to prevent it from shifting during use and affecting its detection effect. When it is necessary to measure the workpiece, the infrared sensor 11 can determine the dust concentration based on the intensity of reflected light. If there is dust on the probe 5, it may affect the intensity or signal of the reflected light, causing abnormal sensor readings. Then, it can transmit alarm information to the alarm 10, which can process the information and issue an alarm to remind the staff to clean the probe 5 and prevent excessive dust from adhering to the probe 5, affecting its detection data. During use, the temperature sensor 4 can sense the temperature information at the workpiece detection point to prevent the temperature from being too high, and the optical sensor 12 can sense the position information of the workpiece. The temperature sensor 4 and the optical sensor 12 transmit the sensed information to the control system, which controls its movement. Then, the probe 5 and the infrared probe 2 can measure and detect the workpiece data information and transmit it to the data control system for collection and processing.
