Description

Technical Field

[0001] This invention belongs to the field of intelligent manufacturing technology, and in particular relates to a production equipment for a drive shaft for an angle grinder. Background Technology

[0002] In the field of angle grinder drive shaft production and processing, cutting is a key process that determines the dimensional accuracy of shaft parts. Its core objective is to remove material by cutting so that the key dimensions of the drive shaft, such as the shaft diameter and keyway, meet the design requirements. For example, in the announcement number CN111673094A, an automatic production equipment for motor drive shaft is disclosed.

[0003] However, existing production equipment cannot obtain diameter data in real time during the cutting process. Due to the lack of real-time diameter data feedback, the cutting parameters of the drive shaft (such as feed rate and cutting depth) cannot be dynamically adjusted, which easily leads to insufficient cutting (residual allowance > 0.1mm, requiring secondary processing) or excessive cutting (out of tolerance and scrap). Insufficient cutting requires secondary processing, while excessive cutting directly leads to the scrapping of the drive shaft. This not only reduces production efficiency and increases costs, but also causes unstable product quality and aggravates equipment wear and tear.

[0004] Therefore, a production equipment for the drive shaft of an angle grinder is proposed. Summary of the Invention

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] like Figures 1-6 As shown, a production equipment for a drive shaft of an angle grinder includes a base 1 and a drive box 2 disposed on one side of the top of the base 1. A three-jaw chuck 3 is rotatably mounted on the side wall of the drive box 2. A gear drive assembly (not shown in the figure) is disposed inside the drive box 2, and the gear drive assembly is fixedly connected to the three-jaw chuck 3. The equipment also includes: The moving mechanism 4 is located on the top of the machine base 1, and a rotating tool holder 5 is located on the top of the moving mechanism 4. The moving mechanism 4 can drive the rotating tool holder 5 to adjust its position in the X-axis and Y-axis directions. The moving mechanism 4 includes a support platform 41 fixedly installed on the top of the machine base 1. A recovery chamber 10 is fixedly installed on the top of the machine base 1 and located between the drive box 2 and the support platform 41. The recovery chamber 10 can collect the waste generated during the cutting process. An X-axis electric slide rail 42 is fixedly installed on the top of the support platform 41. An X-axis electric slide block 43 is installed on the top of the X-axis electric slide rail 42. A Y-axis electric slide rail 44 is fixedly installed on the top of the X-axis electric slide block 43. A Y-axis electric slide block 45 is installed on the top of the Y-axis electric slide rail 44. The rotating tool holder 5 is fixedly installed on the top of the Y-axis electric slide block 45. When the X-axis electric slide rail 42 and the Y-axis electric slide rail 44 are activated, the X-axis electric slide rail 42 and the Y-axis electric slide rail 44 move together, so that the blade on the rotating tool holder 5 is accurately aligned with the workpiece.

[0021] A dynamic feed rate monitoring mechanism 6 is located on top of the moving mechanism 4 and is used to dynamically monitor the feed rate of the rotary tool holder 5. The dynamic feed rate monitoring mechanism 6 includes a mounting plate 61 fixedly mounted on the side wall of the X-axis electric slide 43. A monitoring box 62 is fixedly mounted on the upper surface of the mounting plate 61. A resistance rod 63 is horizontally fixed inside the monitoring box 62. A conductive sleeve 64 is slidably mounted on the wall of the resistance rod 63. An insulating fixing block 65 is fixedly mounted outside the conductive sleeve 64. A connecting block 66 is fixedly provided at the bottom of 65. A connecting rod 67 extending to the outside of the monitoring box 62 is fixedly provided on the side wall of the connecting block 66. The end of the connecting rod 67 away from the connecting block 66 is fixedly connected to the bottom of the Y-axis electric slide 45. When the Y-axis electric slide 45 moves, it drives the connecting block 66 to move linearly inside the monitoring box 62 through the connecting rod 67. The connecting block 66 is linked with the insulating fixing block 65, so that the conductive sleeve 64 slides synchronously on the resistor rod 63, thereby dynamically adjusting the resistance value of the resistor rod 63 connected to the circuit.

[0022] A cutting temperature detection mechanism 7 is located on the top side of the machine base 1, with its end extending above the cutting head of the rotary tool holder 5. The cutting temperature detection mechanism 7 includes a support tube 71 fixedly mounted on the top of the Y-axis electric slide 45. The end of the support tube 71 extends above the cutting head of the rotary tool holder 5, and a temperature sensor 72 is detachably mounted on the end of the support tube 71. An exhaust box 73 is fixedly mounted on the top of the machine base 1, and an exhaust fan 74 is fixedly mounted on the side wall of the exhaust box 73. A filter screen 75 is fixedly mounted inside the exhaust box 73. A disassembly plate is mounted on the top of the exhaust box 73 and is fixedly connected to the filter screen 75 for disassembling and maintaining the filter screen 75 (the disassembly plate is not shown in the diagram). An exhaust pipe 76 is fixedly mounted on the top of the exhaust box 73, with one end of the exhaust pipe 76 away from the exhaust box 73 fixedly connected to the wall of the support tube 71. The exhaust fan 74 operates... The system is transformed into a negative pressure field, which rapidly exhausts the air inside the exhaust box 73, exhaust pipe 76, and support pipe 71, putting the pipeline system in a negative pressure state. This negative pressure effect drives the hot air around the blank cutting area into the interior of the exhaust pipe 76. The temperature sensor 72 can detect the temperature of the hot air. At the same time, the gas entering the exhaust box 73 is filtered through the filter screen 75. Finally, the clean gas is discharged to the outside through the exhaust fan 74. A mounting bracket 77 is fixedly provided on the inner wall of the end of the support pipe 71. The middle of the mounting bracket 77 has a screw hole that is threaded to the temperature sensor 72, so that the temperature sensor 72 can be screwed off from the end of the support pipe 71 for easy maintenance. A protective net 78 is fixedly provided at the end of the support pipe 71 to isolate the temperature sensor 72. The protective net 78 can isolate and protect the temperature sensor 72.

[0023] Cooling mechanism 8 is located on one side of the top of machine base 1, and its end extends to the oblique upper part of the cutting head of rotary tool holder 5. Cooling mechanism 8 includes a liquid supply tank 81 fixedly installed on the top of machine base 1. The side wall of liquid supply tank 81 is provided with a liquid replenishment pipe for adding coolant (not shown in the figure). Liquid supply tank 81 is fixedly provided with a liquid pump 82 and a cooler 83. The output end of liquid pump 82 is fixedly provided with a liquid supply pipe 84 extending to the outside of liquid supply tank 81. The outer wall of the end of support pipe 71 is fixedly provided with a bracket 85, and the inside of bracket 85 is fixedly provided with a spray head 86 at an angle. The end of liquid supply pipe 84 away from liquid supply tank 81 is fixedly connected to spray head 86. When liquid pump 82 and cooler 83 are started, cooler 83 cools the coolant (such as emulsion) in liquid supply tank 81, and liquid pump 82 delivers low temperature coolant to spray head 86 through liquid supply pipe 84, which is then accurately sprayed onto the cutting area of ​​the blank to achieve efficient conduction and diffusion of cutting heat.

[0024] The PLC controller 9 is fixedly installed on the side wall of the drive box 2. The drive box 2, the moving mechanism 4, the feed dynamic monitoring mechanism 6, the cutting temperature detection mechanism 7, and the cooling mechanism 8 are all electrically connected to the PLC controller 9.

[0025] The operating principle of the present invention is described as follows: The operator first clamps the drive shaft blank in the three-jaw chuck 3, and inputs the target diameter data of the drive shaft through the manual operation of the PLC controller 9. Then, the control system of the PLC controller 9 starts the gear transmission drive group, the X-axis electric slide rail 42 and the Y-axis electric slide rail 44 in the automatic drive box 2. The gear transmission drive group drives the three-jaw chuck 3 and the blank to rotate at high speed. The X-axis electric slide rail 42 and the Y-axis electric slide rail 44 move in coordination, so that the blade on the rotating tool holder 5 is accurately aligned with the blank and the cutting operation is started synchronously. When the cutting blade of the rotary tool holder 5 feeds along the Y-axis, the Y-axis electric slide 45 drives the connecting block 66 to move linearly inside the monitoring box 62 via the connecting rod 67. The connecting block 66, in conjunction with the insulating fixing block 65, causes the conductive sleeve 64 to slide synchronously on the resistor rod 63, thereby dynamically adjusting the resistance value of the resistor rod 63 connected to the circuit. As the cutting progresses, the diameter of the billet gradually decreases, and the movement of the conductive sleeve 64 causes the resistance value to decrease linearly, resulting in a corresponding increase in the circuit current. The measuring circuit collects the current change signal at both ends of the resistor rod 63 in real time, and after amplification and filtering, transmits it to the PLC controller 9. The built-in algorithm of the PLC controller 9 maps the real-time current value to the current diameter data of the billet (for every 1m change in current). A, corresponding to a change in billet diameter of 0.02mm, i.e., a feed distance of 0.01mm in the Y-axis direction), is dynamically compared with the initially input target diameter data. The system automatically adjusts the feed amount of the Y-axis electric slide 45 according to the difference between the two. When the real-time diameter is greater than the target diameter, the Y-axis electric slide 45 is driven to continue feeding. When the two data match, a stop command is immediately triggered to complete the precise cutting. This process constructs a closed-loop control circuit through real-time feedback of resistance-current signals, realizing dynamic monitoring and precise control of the feed amount in the billet cutting process, effectively avoiding the problems of insufficient cutting (excessive residual material) or excessive cutting (out-of-tolerance scrapping), and ensuring that the dimensional accuracy of the transmission shaft meets the design requirements. During the cutting process, the operator starts the exhaust fan 74 via the PLC controller 9. The exhaust fan 74 operates at high speed, creating a negative pressure field that rapidly exhausts the air inside the exhaust box 73, exhaust pipe 76, and support pipe 71, placing the pipeline system in a negative pressure state. This negative pressure effect drives the hot air (including cutting heat and frictional heat) around the blank cutting area to be drawn in along the exhaust pipe 76. When the air flows past the temperature sensor 72 at the end of the support pipe 71, the temperature sensor 72 collects the hot air temperature data in real time. The air entering the exhaust box 73 is filtered through the filter screen 75. Finally, the clean air is discharged outward through the exhaust fan 74. The temperature sensor 72 then transmits the real-time temperature value to the PLC controller 9 in the form of an electrical signal. The built-in logic module of the PLC controller 9 dynamically adjusts the processing parameters according to the temperature change gradient. When the temperature rises to ≤20℃: it is determined to be within the normal cutting heat dissipation range, and the current feed speed of the X-axis electric slide rail 42 (transverse feed) and Y-axis electric slide rail 44 (longitudinal feed) is maintained (e.g., 0.1mm / r). When the temperature rises by 20-50℃: a first-level warning is triggered, and the PLC controller 9 automatically reduces the feed speed by 20% (e.g., from 0.1mm / r to 0.08mm / r). When the temperature rises above 50℃: a level two warning is triggered, the feed speed drops sharply to 0.05mm / r, and the exhaust fan is activated in high-speed mode 74 (airflow increased to 500m³ / h). 3If the temperature continues to rise above the threshold (e.g., the upper limit is set to 150℃), the system will automatically stop the cutting operation to prevent the tool from overheating and wearing or the billet from thermally deforming. This closed-loop control process uses a linkage mechanism of "hot gas extraction - temperature detection - parameter adjustment" to achieve dynamic monitoring of cutting temperature and adaptive adjustment of feed rate, avoiding tool life reduction or blank size accuracy deviation caused by excessive temperature, and ensuring that the cutting process is carried out stably in a constant thermal environment. During the cutting process, the operator activates the liquid pump 82 and the cooler 83 via the PLC controller 9. The cooler 83 controls the cooling of the coolant (such as emulsion) in the supply tank 81, while the liquid pump 82 delivers the low-temperature coolant through the supply pipe 84 to the spray head 86, precisely spraying it onto the cutting area of ​​the workpiece to achieve efficient heat transfer and diffusion. Simultaneously, the system dynamically adjusts the power of the cooler 83 and the flow rate of the liquid pump 82 based on real-time data from the temperature sensor 72. When the temperature rises by ≤20℃: within the normal range The cooler maintains its base power (e.g., 20% of rated power), and the coolant temperature in the liquid supply tank 81 is maintained at 18-22℃ (default operating temperature). Pump 82: delivers coolant at a standard flow rate of 10L / min, and spray nozzle 86 maintains low-speed atomization to ensure mild cooling of the cutting edge (expected temperature drop of 5-10℃). Temperature rise of 20-50℃: Level 1 warning Refrigerator 83: Power is increased to 50% of rated power, coolant temperature is reduced to 15-18℃, and heat exchange capacity is enhanced; Liquid pump 82: Flow rate increased to 20L / min, spray head 86 switched to medium-pressure direct injection mode (pressure 1.5MPa) to directly flush the cutting zone, expected to cool down by 15-25℃; Temperature rise > 50℃: Level II warning Refrigerator 83: Full power operation (100%), coolant temperature drops sharply to 10-12℃, and stirring device is activated to prevent temperature stratification; Liquid pump 82: The flow rate jumps to 30L / min, and the liquid nozzle 86 starts high-pressure injection mode (pressure 3MPa) to form a ring-shaped cooling curtain, which is expected to reduce the temperature by 30-40℃; Once the target diameter is reached, the built-in system of the PLC controller 9 will automatically stop the equipment, and the operator will then remove the processed drive shaft from the three-jaw chuck 3.
