Description

Technical Field

[0001] This application relates to the field of parts processing and testing, and in particular to a device for parts hole processing and thread testing. Background Technology

[0002] In industries such as metal products, plastic products, molds, machinery and equipment, automobiles and their parts, and electronics, the processing and manufacturing of spare parts is of widespread demand and significant importance. With continuous industrial development, the processing technology for these spare parts is also constantly improving, and their quality and precision directly affect the performance and stability of related products. For example, in the automotive manufacturing field, high-quality spare parts can improve the overall quality and safety of automobiles, playing a crucial role in driving industry development. Furthermore, as market demands for product quality and production efficiency continue to rise, optimizing the processing flow of spare parts has become a focus of attention within the industry.

[0003] In traditional parts processing, for parts requiring internal hole cleaning and internal thread inspection, the conventional approach is to assign different personnel and equipment to perform these tasks. Operators use different equipment in different areas to perform the corresponding processing steps; for example, cleaning the internal hole in one area and then moving to another area for internal thread inspection. Even with semi-automatic equipment or equipment for individual processes, it is still necessary to transfer parts between different processes. While this method can complete the parts processing to some extent, it also involves numerous operational steps.

[0004] However, this conventional implementation method requires significant manual intervention, resulting in high labor costs. Furthermore, each piece of equipment occupies its own area, leading to a large processing space requirement. Simultaneously, due to the high level of human involvement, human factors have a greater impact on product quality, easily causing inconsistencies. In addition, even when using semi-automatic equipment or individual process equipment, transferring parts between different processes is time-consuming and labor-intensive, severely impacting production efficiency. Summary of the Invention

[0005] In order to automate multiple processes, improve yield and efficiency, and reduce labor costs, this application provides a device for processing fitting holes and testing threads.

[0006] This application provides a fitting hole processing and thread testing device, which adopts the following technical solution: A fitting hole processing and thread testing device includes a worktable and a turntable. The turntable is rotatably connected to the worktable along its vertical axis. A plurality of mounting blocks for fixing fittings are uniformly fixed circumferentially on the upper surface of the turntable. The upper surface of the worktable is fixed circumferentially along the worktable with sequentially arranged, corresponding one-to-one mounting blocks, a loading station, a pre-test cleaning station, a hole processing station, a thread testing station, a post-test cleaning station, and a unloading station. The hole processing station includes a plurality of cleaning needles corresponding one-to-one with the threaded holes of the fittings to be tested and a first lifting component. A drive motor is coaxially fixedly connected to the cleaning needles. The first lifting component drives the cleaning needles to extend into the threaded holes of the fittings. The thread testing station includes a testing motor, a testing screw, and a displacement device. The displacement device and the first lifting component are both fixed to the upper surface of the worktable. The displacement device drives the testing screw to extend into the threaded hole to be tested. The testing motor drives the testing screw to rotate. The testing motor is connected to an alarm device.

[0007] By adopting the above technical solution, the turntable is rotatably connected to the worktable along the vertical axis. The mounting blocks on the turntable can fix the parts and, as the turntable rotates, sequentially pass through the loading station, pre-inspection cleaning station, hole treatment station, thread inspection station, post-inspection cleaning station, and unloading station, realizing the automatic transfer of parts between different processes and improving processing efficiency. The pre-inspection cleaning station can pre-clean the threaded holes of the parts, removing debris and impurities, providing a good foundation for subsequent hole treatment and thread inspection. In the hole treatment station, the first lifting component drives the cleaning needle to extend into the threaded hole of the part, and the drive motor drives the cleaning needle to rotate, which can more deeply clean the threaded hole and further remove impurities in the hole, ensuring the cleanliness of the hole. In the thread inspection station, the displacement device drives the inspection screw to extend into the threaded hole to be inspected, and the inspection motor drives the inspection screw to rotate, which can accurately detect whether the thread meets the requirements. If there is a problem with the part, the alarm device will promptly alarm and stop the machine, preventing unqualified products from entering subsequent processes and improving the product yield. The entire equipment integrates multiple processes, achieving fully automated completion of multiple processes, reducing manual intervention and labor costs, while also reducing quality problems caused by human factors, which meets the needs of industrial transformation and upgrading.

[0008] Optionally, an installation plate is provided above the turntable. The installation plate is fixedly connected to the worktable. A clamping cylinder is fixedly provided on the upper surface of the installation plate, which corresponds to the cleaning station before inspection, the hole treatment station, the thread inspection station, and the cleaning station after heat exchange inspection. A clamping plate is fixedly provided on the telescopic end of the clamping cylinder. The clamping plate and the installation block together clamp the parts to be processed.

[0009] By adopting the above technical solution, the mounting plate is fixedly connected to the worktable, providing a stable mounting foundation for the clamping cylinders. Clamping cylinders, each corresponding to a pre-inspection cleaning station, hole treatment station, thread inspection station, and post-inspection cleaning station, are installed on the upper surface of the mounting plate, functioning at each critical station. When the part rotates to the corresponding station with the turntable, the telescopic end of the clamping cylinder drives the clamping plate to move, causing the clamping plate and the mounting block to clamp the part to be processed. This ensures that at the pre-inspection cleaning station, the part remains stable during air blowing to remove debris and prevents movement that could affect the cleaning effect. At the hole treatment station, it ensures that the part does not shift when the motor-driven wire extends into the hole for cleaning, improving cleaning accuracy. At the thread inspection station, it allows for more accurate and reliable drilling of the hole with an externally threaded drill bit to check if the thread meets requirements; if a problem is found with the part, the equipment can accurately alarm and stop. At the post-inspection cleaning station, it ensures that the part's position remains fixed during subsequent air blowing to remove debris and improves cleaning quality. This improves the stability and accuracy of the entire equipment in processing fitting holes and testing threads, ensuring the processing quality and testing effect of products, and further enhancing the equipment's working efficiency and yield rate.

[0010] Optionally, a positioning sensor is fixedly installed on the upper surface of the turntable to detect the installation status of the accessories in the mounting block of the feeding station.

[0011] By adopting the above technical solution and installing a positioning sensor on the upper surface of the turntable, the installation status of components within the mounting block at the feeding station can be accurately detected. When the component is correctly installed in the mounting block, the positioning sensor can promptly provide feedback, ensuring the smooth progress of subsequent processing steps. If the component is not correctly installed, the sensor can immediately send a signal to remind the operator to make adjustments, avoiding problems in subsequent processing due to improper component installation. This improves the stability of equipment operation and processing accuracy, reduces the defect rate, and enhances overall production efficiency.

[0012] Optionally, the turntable is provided with a material conveying pipe above the loading station. The inner wall of the material conveying pipe is adapted to the shape of the accessory. Two pressure plates that move in opposite directions in the horizontal direction are provided below the material conveying pipe. The pressure plates slide in the vertical direction. A first pneumatic finger cylinder is fixedly provided on the pressure plate. A first lifting cylinder is fixedly provided on the first finger cylinder. The cylinder body of the first lifting cylinder is fixedly connected to the worktable.

[0013] By adopting the above technical solution, when feeding parts, the conveyor pipe can store parts, and its inner wall is adapted to the shape of the parts to ensure orderly conveying. Two pressure plates that move in opposite directions horizontally can be adjusted according to the size of the parts for better handling. The pressure plates slide vertically, working in conjunction with the first pneumatic finger cylinder and the first lifting cylinder to flexibly grasp and place parts, achieving precise feeding of parts from the conveyor pipe to the mounting block on the turntable. This improves feeding accuracy and efficiency, reduces manual intervention, and thus lowers labor costs.

[0014] Optionally, two collection boxes are provided below the turntable and abut against the upper end of the worktable. The two collection boxes are used to collect qualified parts and unqualified parts respectively. The turntable has a discharge port between two adjacent mounting blocks. A material picking device is provided on one side of the collection box and is installed on the upper end of the worktable.

[0015] By adopting the above technical solution, the two collection boxes located below the turntable are used to collect qualified and unqualified parts respectively, enabling the classification and collection of parts with different test results and avoiding confusion between parts of different quality. The feeding port on the turntable allows parts to fall smoothly from the turntable into the corresponding collection box, achieving an efficient feeding process. Simultaneously, a material handling device located on one side of the collection box is installed on the end face of the worktable, facilitating further operation or transfer of the parts within the collection box, improving the overall automation level and work efficiency of the equipment, reducing manual intervention, and lowering labor costs.

[0016] Optionally, the material handling device includes a second lifting cylinder, a second pneumatic finger cylinder, and several inserts adapted to the side wall of the accessory. The inserts are fixedly connected to the telescopic end of the second pneumatic finger cylinder, the cylinder body of the second pneumatic finger cylinder is fixedly connected to the telescopic end of the second lifting cylinder, and the cylinder body of the second lifting cylinder is fixedly connected to the worktable.

[0017] By adopting the above technical solution, the second lifting cylinder in the material handling device can drive the second pneumatic finger cylinder to move up and down. The second pneumatic finger cylinder can control the opening and closing of the insert block. Since the insert block is adapted to the side wall of the accessory, when the second pneumatic finger cylinder retracts, the insert block can closely fit the side wall of the accessory and grab it. Then, through the rising action of the second lifting cylinder, the accessory is taken out from the mounting block, realizing efficient and accurate material handling operation of the accessory. It is convenient to transfer qualified or unqualified accessories to the corresponding collection boxes, thereby improving the automation level and work efficiency of the equipment.

[0018] Optionally, both the pre-inspection cleaning station and the post-inspection cleaning station include a second lifting component and several jet pipes that correspond one-to-one with the threaded holes of the accessories, with the telescopic end of the second lifting component fixedly connected to the jet pipes.

[0019] By adopting the above technical solution, a second lifting component and an air jet pipe are installed at both the pre-inspection cleaning station and the post-inspection cleaning station. The second lifting component can drive the air jet pipe to approach or move away from the threaded hole of the component. Before inspection, the air jet pipe can blow air into the threaded hole of the component, effectively cleaning the debris and foreign matter inside, preventing debris and foreign matter from affecting subsequent hole processing and thread inspection processes, and ensuring the accuracy of inspection results. After inspection, the threaded hole is cleaned again by blowing air through the air jet pipe, which can remove new debris and foreign matter that may have been generated during the inspection process, ensuring the cleanliness of the component and further improving the product yield.

[0020] Optionally, the displacement device includes a vertical electric track, a longitudinal electric track, and a transverse electric track. The longitudinal electric track is connected to a detection motor. The displacement device is used to drive the detection screw to extend sequentially into several threaded holes of the accessory.

[0021] By adopting the above technical solution, the vertical electric track, longitudinal electric track, and transverse electric track in the displacement device work together to precisely drive the detection screw to move in multiple dimensions, thereby sequentially extending into several threaded holes of the accessory, realizing accurate detection of each threaded hole, improving the efficiency and accuracy of thread detection, effectively avoiding the problem of detection omissions or inaccuracies that may be caused by manual operation, and making the equipment more comprehensive and reliable in detecting the threads of accessories.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The turntable rotates along its vertical axis and is connected to the worktable. Mounting blocks on the turntable secure the parts, which then rotate through the loading station, pre-inspection cleaning station, hole treatment station, thread inspection station, post-inspection cleaning station, and unloading station. This automatic transfer of parts between different processes improves processing efficiency. The pre-inspection cleaning station pre-cleans the threaded holes of the parts, removing debris and providing a good foundation for subsequent hole treatment and thread inspection. In the hole treatment station, the first lifting component drives a cleaning needle into the threaded hole of the part. The drive motor rotates the cleaning needle, allowing for deeper cleaning of the threaded hole and further removal of impurities, ensuring hole cleanliness. In the thread inspection station, a displacement device drives a detection screw into the threaded hole to be inspected. The detection motor drives the detection screw to rotate, accurately detecting whether the thread meets requirements. If a part has a problem, an alarm device will promptly sound an alarm and stop the machine, preventing unqualified products from entering subsequent processes and improving the product yield. The entire equipment integrates multiple processes, achieving fully automated completion of multiple processes, reducing manual intervention and labor costs, while also reducing quality problems caused by human factors, which meets the needs of industrial transformation and upgrading; 2. The mounting plate is fixedly connected to the worktable, providing a stable mounting base for the clamping cylinders. Clamping cylinders, corresponding to the pre-inspection cleaning station, hole treatment station, thread inspection station, and post-inspection cleaning station respectively, are installed on the upper surface of the mounting plate, functioning at each critical station. When the part rotates to the corresponding station with the turntable, the telescopic end of the clamping cylinder drives the clamping plate to move, causing the clamping plate and the mounting block to clamp the part to be processed. This ensures that at the pre-inspection cleaning station, the part is stably fixed when blowing air to clean debris from the hole, preventing the cleaning effect from being affected by the part's movement; at the hole treatment station, it ensures that the part will not shift when the motor-driven wire extends into the hole for cleaning, improving cleaning accuracy; at the thread inspection station, it allows the drill bit with external threads to rotate and drill into the hole to check if the thread meets the requirements more accurately and reliably; if there is a problem with the part, the equipment can accurately alarm and stop; at the post-inspection cleaning station, it ensures that the part's position is fixed when blowing air to clean debris from the hole again, improving cleaning quality. This improves the stability and accuracy of the entire equipment in processing accessory holes and testing threads, ensuring the processing quality and testing effect of products, and further improving the working efficiency and yield of the equipment. 3. A positioning sensor is installed on the upper surface of the turntable to accurately detect the installation status of components within the mounting block at the loading station. When a component is correctly installed in the mounting block, the positioning sensor provides timely feedback, ensuring smooth operation of subsequent processing steps. If a component is not correctly installed, the sensor immediately sends a signal to remind the operator to make adjustments, preventing problems in subsequent processing due to improper component installation. This improves the stability and accuracy of equipment operation, reduces the defect rate, and enhances overall production efficiency. Attached Figure Description

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] This application discloses a fitting hole processing and thread testing device.

[0031] Reference Figure 1 and Figure 2 A device for processing holes and testing threads of fittings includes a workbench 1 and a turntable 2. The turntable 2 is rotatably connected to the workbench 1 along its own vertical axis. Several mounting blocks 21 for fixing fittings are uniformly fixed on the upper surface of the turntable 2 along the circumference. The upper surface of the workbench 1 is fixed with a loading station 8, a pre-inspection cleaning station 5, a hole processing station 3, a thread inspection station 4, a post-inspection cleaning station 7, and a unloading station 9 arranged sequentially and corresponding one-to-one with the mounting blocks 21. This layout allows fittings to be processed sequentially at different stations, improving production efficiency.

[0032] Reference Figure 1 and Figure 2The hole processing station 3 includes several cleaning needles 31 corresponding one-to-one with the threaded holes of the parts to be inspected, and a first lifting component 32. The cleaning needles 31 are coaxially fixedly connected to a drive motor 33. The cleaning needles 31 are typically made of metal, possessing a certain degree of hardness and wear resistance, effectively cleaning debris from the threaded holes. They are slender needles to facilitate insertion into the threaded holes. Replaceable features include cleaning needles 31 made of different materials, such as ceramic, which offers better wear resistance and corrosion resistance. The first lifting component 32 can be a cylinder, driven by pneumatic pressure to achieve lifting action. It is mounted on the worktable 1 and connected to the cleaning needles 31, precisely controlling the lifting height of the cleaning needles 31 to ensure accurate insertion into the threaded holes of the parts. The drive motor 33 is fixed to one end of the cleaning needles 31, providing rotational power. The drive motor 33 can be a servo motor with precise speed control and torque output, or a stepper motor, which is relatively low-cost. When the first lifting component 32 drives the cleaning needle 31 to extend into the threaded hole of the accessory, the drive motor 33 drives the cleaning needle 31 to rotate, thereby cleaning the threaded hole and removing debris and impurities inside the hole.

[0033] Reference Figure 1 and Figure 2 The thread inspection station 4 includes an inspection motor 41, an inspection screw 42, and a displacement device 43. The displacement device 43 and the first lifting component 32 are both fixed to the upper surface of the worktable 1. The inspection screw 42 is generally made of high-strength alloy steel with a specially treated surface, exhibiting good thread accuracy and wear resistance. Its shape is adapted to the threaded hole to be inspected, allowing it to be accurately screwed into the threaded hole for inspection. A replaceable feature is the use of different inspection screws 42, such as a plastic inspection screw 42, for inspecting some threaded holes with lower precision requirements. The displacement device 43 includes a vertical electric track 431, a longitudinal electric track 432, and a transverse electric track 433. The longitudinal electric track 432 is connected to the inspection motor 41, and precise motor control enables the movement of the inspection screw 42 in three-dimensional space, driving the inspection screw 42 to sequentially extend into several threaded holes of the accessory. The detection motor 41 is connected to an alarm device. When the detection screw 42 encounters an abnormality during the screwing into the threaded hole, such as when the thread does not meet the requirements, the alarm device will sound an alarm and the equipment will stop so that the problem can be dealt with in a timely manner.

[0034] Reference Figure 2A mounting plate 6 is located above the turntable 2 and is fixedly connected to the workbench 1. A clamping cylinder 61 is fixedly mounted on the upper surface of the mounting plate 6, corresponding to the pre-inspection cleaning station 5, the hole treatment station 3, the thread inspection station 4, and the post-inspection cleaning station 7, respectively. A clamping plate 62 is fixedly mounted on the telescopic end of the clamping cylinder 61. The clamping plate 62 and the mounting block 21 together clamp the parts to be processed. The clamping cylinder 61 can be a single-acting cylinder, driven by air pressure to extend or retract its telescopic end. The clamping plate 62 is usually made of rubber, possessing a certain degree of elasticity, which can prevent damage to the parts when clamping them. When the parts move to the corresponding station, the clamping cylinder 61 drives the clamping plate 62 to descend, ensuring the stability of the parts during processing.

[0035] Reference Figure 2 A position sensor 22 is fixedly installed on the upper surface of the turntable 2 to detect the installation status of the parts in the mounting block 21 of the loading station 8. The position sensor 22 can be a photoelectric sensor, which detects whether the parts are installed in place by emitting and receiving light. When the parts are installed in place, the position sensor 22 will send a signal to indicate that the equipment can proceed to the next step.

[0036] Reference Figure 3 and Figure 4 Below the turntable 2 are two collection boxes 13 that abut against the upper end of the workbench 1. The two collection boxes 13 are used to collect qualified parts and unqualified parts, respectively. The collection boxes 13 can be made of plastic or metal and have a certain capacity. The turntable 2 has a discharge port 23 between two adjacent mounting blocks 21. A picking device 14 is provided on one side of the collection box 13 and is installed on the upper surface of the workbench 1. After the picking device 14 removes the qualified or unqualified parts from the mounting block 21, they fall into the collection box 13 from the corresponding discharge port 23. The picking device 14 includes a second lifting cylinder 141, a second pneumatic finger cylinder 142, and several inserts 143 that are adapted to the side wall of the parts. The inserts 143 are fixedly connected to the telescopic end of the second pneumatic finger cylinder 142. The cylinder body of the second pneumatic finger cylinder 142 is fixedly connected to the telescopic end of the second lifting cylinder 141. The cylinder body of the second lifting cylinder 141 is fixedly connected to the workbench 1. The second lifting cylinder 141 drives the second pneumatic finger cylinder 142 to rise or fall. The second pneumatic finger cylinder 142 grabs the accessory through the insert block 143, removes it from the mounting block 21, and drops it into the corresponding collection box 13 through the discharge port 23.

[0037] Reference Figure 3 and Figure 5Above the loading station 8, the turntable 2 is equipped with a conveying pipe 11. The inner wall of the conveying pipe 11 is adapted to the shape of the parts and is used to transport the parts. The conveying pipe 11 can be made of plastic, which has good wear resistance and smoothness, facilitating the sliding of the parts. Below the conveying pipe 11, there are two pressure plates 12 that move in opposite directions in the horizontal direction. The pressure plates 12 slide in the vertical direction. A first pneumatic finger cylinder 121 is fixedly mounted on the pressure plate 12. A first lifting cylinder 122 is fixedly mounted on the first finger cylinder. The cylinder body of the first lifting cylinder 122 is fixedly connected to the worktable 1. The first pneumatic finger cylinder 121 is used to grip the parts. The first lifting cylinder 122 drives the pressure plate 12 and the first pneumatic finger cylinder 121 to rise or fall, accurately placing the parts on the mounting block 21.

[0038] Reference Figure 2 Both the pre-inspection cleaning station 5 and the post-inspection cleaning station 7 include a second lifting component 51 and several air jet pipes 52 corresponding one-to-one with the threaded holes of the accessories. The telescopic end of the second lifting component 51 is fixedly connected to the air jet pipes 52. The second lifting component 51 can be an electric push rod, driven by a motor to achieve the lifting action. The air jet pipes 52 are made of metal or plastic, with good corrosion resistance and sealing performance. When the second lifting component 51 drives the air jet pipes 52 to descend to the appropriate position, the air jet pipes 52 blow air into the threaded holes of the accessories to clean the debris and impurities inside the holes.

[0039] The implementation principle of the accessory hole processing and thread testing equipment in this application embodiment is as follows: The equipment uses the rotation of turntable 2 to sequentially transport accessories to various workstations for processing. At the loading station 8, the accessory is placed on the mounting block 21 via the conveying pipe 11 and the picking device 14, and the position sensor 22 detects the accessory's installation status. At the pre-test cleaning station 5, the air jet pipe 52 blows air to clean the threaded holes of the accessory. At the hole processing station 3, the cleaning needle 31 further cleans the threaded holes. At the thread testing station 4, the thread is tested via the testing screw 42; if a problem is found, an alarm device sounds. At the post-test cleaning station 7, the threaded holes are blown air to clean again. Finally, the picking device 14 removes the accessory from the mounting block 21 and places it into the corresponding collection box 13 according to the test results. This layout and working method achieves fully automated completion of multiple processes, greatly improving production efficiency and yield, while reducing labor costs.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
