Abstract
Description
Technical Field
[0001] The utility model relates to the field of automatic control, and more specifically, to an intelligent tapping workstation. Background Art
[0002] A tapping machine is a device widely used in machining and other fields, primarily for producing internal threads on workpieces. It typically consists of a power mechanism, transmission mechanism, feed mechanism, and tap fixture. The power mechanism provides the necessary power for the tapping operation. Common types include electric and pneumatic. Electric tapping machines offer stable power and adjustable output, while pneumatic tapping machines are characterized by their quick response, lightness, and portability.
[0003] However, existing tapping machines typically use tapping oil during the tapping operation to lubricate, cool the tap, and facilitate chip removal. This oil continuously drips from the tapping area onto the work surface, and waste chips generated by the tapping operation are scattered across the work surface. This makes cleaning difficult, forcing workers to completely clean the entire work surface, which undoubtedly consumes a significant amount of time and effort, and introduces inconvenience to daily production and maintenance. Furthermore, when multiple threaded holes need to be machined on a workpiece, errors can occur. For example, sometimes missed tapping occurs, where the location where the threaded hole should be machined is omitted, resulting in an incomplete number of threaded holes on the workpiece. Other times, tapping may fail to reach the specified depth, where the tap fails to fully machine the thread, resulting in a hole depth that does not meet the required depth. (These unexpected situations can be caused by program errors, severe tap wear, low machine precision, operator error, and other factors.) These problems can seriously affect the quality of the product produced.
[0004] Therefore, in order to solve the above technical problems, the present application proposes an intelligent tapping workstation. Utility Model Content
[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an intelligent tapping workstation.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an intelligent tapping workstation, comprising an oil collection workbench, and a CNC tapping machine fixed to the top corner of the oil collection workbench, wherein a tap is installed on the transmission part of the CNC tapping machine, the bottom of the oil collection workbench is made of iron sheet to form a funnel-shaped feeding opening, which wraps the entire tooling, a plurality of profiling blocks are fixedly connected to the middle part of the top of the oil collection workbench, and the profiling blocks pass through the middle to communicate with the funnel-shaped feeding opening, and the intelligent tapping workstation also includes:
[0007] The electrical components include a PLC controller, indicator lights, a buzzer and a proximity switch, which work together to determine whether the hole has been tapped.
[0008] Preferably, it also includes a fixture assembly, which includes reference blocks fixed on both sides of the top of the oil collecting workbench, and a pressure plate driven by a cylinder installed on the top of the oil collecting workbench corresponding to the tapping position to press down the multiple ear holes that need to be processed to prevent the product from moving upward during tapping.
[0009] Preferably, the CNC tapping machine comprises a servo motor, a controller, a display screen and a bracket.
[0010] Preferably, the tap is an OSG extrusion tap with oil groove, which greatly improves the precision, strength and wear resistance of the thread surface compared to ordinary cutting taps.
[0011] Preferably, a torque protection chuck is installed between the tap and the CNC tapping machine. The torque protection chuck is used to adjust the chuck torque and provide slip protection when the tap reaches the bottom of the blind hole and exceeds its torque.
[0012] Preferably, the electrical component further comprises an air supply device and a solenoid valve, so as to clean the oil collection workbench surface after tapping and blow away the oil and waste chips in the product hole.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The utility model wraps the entire tooling with a funnel-shaped discharge port, and a trash can can be placed at the bottom of the workbench to collect waste dripping oil. When tapping oil used for tapping drips onto the tooling during work, it can slide through the funnel-shaped discharge port into the trash can for collection, thereby keeping the work station clean and reducing the amount of cleaning for the staff in the later stage. When in use, the CNC tapping machine drives the tap downward to tap. When the tap approaches the proximity switch, the proximity switch sends a signal, and the indicator light lights up, indicating that the hole on the product has been tapped through. If the indicator light does not light up, it means that the tap has not been tapped in place. At the same time, if the tap 7 does not tap the product hole or misses tapping, the PLC control system will control the buzzer to sound an alarm and display which hole position on the product has not been tapped in place or missed tapping, thereby timely discovering defective products, which is conducive to improving the production quality of the product and is more intelligent, so as to solve the problems of the background technology in that the staff has a large workload in cleaning the work table and is prone to missed tapping or inadequate tapping.
[0015] 2. The utility model uses multiple cylinders to press the pressing plate downward, thereby pressing down multiple ear holes that need to be processed to prevent the product from moving upward during tapping;
[0016] 3. The CNC tapping machine of the utility model can set the speed during tapping, the speed during thread withdrawal, the tapping depth and the torque protection value, thereby improving the efficiency and quality of CNC tapping. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-4 As shown, the utility model provides an intelligent tapping workstation, including an oil collection workbench 1, and a CNC tapping machine 2 fixed to the top corner of the oil collection workbench 1, a tap 7 is installed on the transmission part of the CNC tapping machine 2, the bottom of the oil collection workbench 1 is made of iron sheet to form a funnel-shaped feeding opening 3, which wraps the entire tooling, and a plurality of profiling blocks 4 are fixedly connected to the middle part of the top of the oil collection workbench 1. The intelligent tapping workstation also includes:
[0024] The electrical component 5 includes a PLC controller, an indicator light, a buzzer and a proximity switch, and the components cooperate to determine whether the hole is tapped through.
[0025] The entire tooling is wrapped by the funnel-shaped discharge port 3, and a trash can can be placed at the bottom of the workbench to collect waste dripping oil. When tapping oil used for tapping drips onto the tooling during work, it can slide into the trash can through the funnel-shaped discharge port 3 and be collected, thereby keeping the work station clean and reducing the amount of cleaning required by the staff in the later stage. When in use, the CNC tapping machine 2 drives the tap 7 downward to tap. When the tap 7 approaches the proximity switch, the proximity switch sends a signal, and the indicator light lights up, indicating that the hole on the product has been tapped through. If the indicator light does not light up, it means that the tap has not tapped in place. Similarly, multiple holes on the product are tapped in sequence (the workpiece processed in the drawings of the present invention has five holes). At the same time, if the tap 7 does not tap the product hole through or misses tapping, the PLC control system will control the buzzer to sound an alarm and display which hole on the product has not been tapped in place or missed tapping, thereby fundamentally eliminating the production of defective products, greatly improving product quality, and being more intelligent.
[0026] Furthermore, the electrical component 5 also includes a button box, an air supply device and a solenoid valve to clean the surface of the oil collection workbench 1 after tapping. That is, after checking that all the indicator lights are on, press the button on the button box to turn on the air supply device, and the PLC controls the solenoid valve to blow air to clean the oil and waste chips in the product hole.
[0027] The present invention also includes a fixture assembly 6, which includes reference blocks 601 fixed on both sides of the top of the oil collecting workbench 1, and a pressure plate 603 driven by a cylinder 602 installed on the top of the oil collecting workbench 1 corresponding to the tapping position. When fixing the product, the product is placed on the profiling block 4 for support. It should be noted that the profiling block 4 passes through the middle and is connected to the funnel-shaped discharge port 3. The tapping oil dripping during tapping and the waste chips generated during tapping can slide into the funnel of the workbench through this through hole and be collected together. Reference holes are opened on both sides of the product, and the reference holes are inserted into the reference blocks 601 for positioning. Then, the pressure plate 603 is pressed down by multiple cylinders 602 (a through hole is opened on the pressure plate 603 for the tap 7 to tap), thereby pressing down multiple ear holes that need to be processed to prevent the product from rising during tapping.
[0028] In addition, the CNC tapping machine 2 of the present invention includes a servo motor 201, a controller, a display screen 202 and a bracket 203, and a torque protection chuck 8 is installed between the tap 7 and the CNC tapping machine 2. The servo motor 201 can convert the voltage signal into torque and speed to drive the control object. The controller is used to control the power supply and torque overload protection, and the feed and retract speed are controlled and adjusted through the display screen 202. The torque protection chuck 8 is used to adjust the chuck torque size, and performs slip protection when the tapping reaches the bottom of the blind hole and exceeds its torque. In this way, the CNC tapping machine 2 can set the speed during tapping, the speed during retracting, the tapping depth and the torque protection value, thereby improving the efficiency and quality of CNC tapping.
[0029] Furthermore, because our G iron frame project is used on BMW panoramic sunroofs, the customer's tapping requirements for this product are very stringent. Therefore, we use OSG oil-grooved extrusion taps imported from Japan. Extrusion taps, also known as chipless taps, grooveless taps, and slotless taps, are chipless, extrusion-molded tools. Extrusion taps produce threads with high precision, achieving a high RH8 accuracy and surface roughness of approximately RA0.3 because there is no cutting interference. Cut threads have continuous metal fibers, resulting in approximately 30% higher strength than cut threads. Furthermore, the cold work hardening caused by extrusion increases the surface hardness of the thread by 40% to 50% compared to the core. This also significantly improves the wear resistance of the thread surface, significantly enhancing the precision, strength, and surface wear resistance of the thread compared to conventional cutting taps.
[0030] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
