Description

Technical Field

[0001] This invention relates to the field of parts manufacturing and testing equipment, specifically to a device for simultaneous testing of the outer diameter and center hole of helical gears. Background Technology

[0002] In the machinery manufacturing industry, the precision and quality of components directly affect the performance and reliability of the final product. For a specific design of a component, its structural features include a center hole at one end and helical threads formed near the outer edge of the other end. These two features each serve different functions. The center hole is often used for installation and positioning, requiring extremely high coaxiality and dimensional accuracy to ensure stable operation of rotating parts and reduce wear. The helical threads, on the other hand, are typically used for tight connections with other components or for transmitting torque; the accuracy of parameters such as pitch, thread angle, and thread depth is crucial for connection strength and sealing performance.

[0003] In traditional final inspection processes, because these two features are relatively independent in spatial location and differ in inspection methods and required equipment, they are usually performed separately at two different workstations. The inspection of the center hole relies on high-precision internal diameter measuring tools to ensure that the hole's positional accuracy and dimensions meet design requirements. The inspection of thread helical teeth, however, is more complex, requiring the use of specialized thread measuring instruments or thread plug gauges. This involves using rotary contact measurement or optical non-contact scanning technology to verify whether the various parameters of the thread meet the standards.

[0004] While this multi-station inspection method can guarantee inspection accuracy, it suffers from low production efficiency and increased costs. Each station change requires repositioning of the parts, which is not only time-consuming but may also introduce new errors due to multiple clamping operations. In addition, multi-station inspection requires more equipment and manpower, increasing overall production costs and management complexity.

[0005] Therefore, as the manufacturing industry moves towards intelligence and automation, optimizing the inspection process and improving inspection efficiency has become an urgent problem to be solved. Especially when facing large-scale production, developing a device that can simultaneously inspect center holes and threaded helical teeth can not only significantly improve inspection speed and reduce production costs, but also enhance the flexibility and adaptability of the production line, which is of great significance for improving the competitiveness of the entire manufacturing process and product quality.

[0038] A device for simultaneous detection of the outer diameter and center hole of helical teeth, such as Figure 1 As shown, a component 100 with a predetermined structure is used for testing. The predetermined structure includes at least a central hole 101 located at one end of the component 100 and a threaded helical tooth 102 near the outer surface of the other end of the component 100.

[0039] like Figure 2-6 As shown, it includes an installation platform 10, a workbench 20, a base 31, a center hole detection component 32, and a helical tooth outer diameter ring gauge detection component 33.

[0040] The base 31 is fixed to the mounting platform 10 and includes a vertically arranged upright plate 313;

[0041] The workbench 20 is horizontally positioned above the mounting platform 10. A testing station 20d for fixing the component 100 is provided on the workbench 20. When the component 100 is fixed at the testing station, the central hole 101 and the threaded helical tooth 102 are located on opposite sides of the workbench 20 in the vertical direction. In this embodiment, the central hole 101 is located at the upper end of the component 100, and when fixed at the testing station, it is located above the surface of the workbench 20. The threaded helical tooth 102 is located on the lower outer side of the component 100, and when fixed at the testing station, it is located below the surface of the workbench 20.

[0042] The center hole detection component 32 and the helical tooth outer diameter ring gauge detection component 33 are both vertically slidably disposed on the upright plate. The detection station 20d is located between the center hole detection component 32 and the helical tooth outer diameter ring gauge detection component 33. The center hole detection component 32 is used to detect the center hole 101; the helical tooth outer diameter ring gauge detection component 33 is used to detect the helical thread 102.

[0043] In one optional embodiment of this application, the center hole detection component 32 is vertically slidably mounted on the upper part of the upright plate 313 for detecting the center hole 101 of the component to be tested 100; the helical tooth outer diameter ring gauge detection component 33 is vertically slidably mounted on the lower part of the upright plate 313 for detecting the thread helical tooth 102 of the component to be tested 100.

[0044] The center hole detection assembly 32 includes an L-plate 321, an XY-axis adjustable slide 322, a center hole contact 323, a bushing 324, a center hole standard detection rod 325, a limit ring 326, a probe fixing L-plate 327, a center hole sensor probe 328, and a compression spring 329.

[0045] L-plate 321 is slidably mounted on the upper part of vertical plate 313 and has a through hole. XY-axis adjustable slide 322 is mounted on the upper end of L-plate. Bushing 324 passes through L-plate 321 and XY-axis adjustable slide 322 and is fixed to the upper end of XY-axis adjustable slide 322.

[0046] The central hole contact 323 is fixed to the lower end of the bushing 324. The central hole standard detection rod 325 includes a rod body 3251 and a standard connector 3252. The rod body 3251 is movably disposed inside the bushing 3252. The central hole contact 323 has a through hole that mates with the standard connector 3252. The limiting ring 326 is connected to the outside of the rod body 3251 and disposed at the upper end of the bushing 324. The outer diameter of the limiting ring 326 is larger than the inner diameter of the bushing 324.

[0047] Preferably, the probe fixing L plate 327 is installed on the upper end of the XY axis adjustable slide 322, the center hole sensor probe 328 is locked on the probe fixing L plate, the center hole sensor probe 328 is coaxially arranged with the rod body 3251, and the compression spring 329 is arranged between the limiting ring 326 and the probe fixing L plate 327.

[0048] By introducing structures such as an L-plate 321, an XY-axis adjustable slide 322, a center hole contact 323, a bushing 324, a center hole standard detection rod 325, a limiting ring 326, a probe fixing L-plate 327, a center hole sensor probe 328, and a compression spring 329, a center hole detection assembly 32 with adjustable height and precise coaxiality calibration is constructed. The sliding installation of the L-plate 321 on the vertical plate 313 provides flexibility in the detection position, while the XY-axis adjustable slide 322 ensures that the coaxiality between the center hole sensor probe 328 and the center hole standard detection rod 325 can be fine-tuned to the optimal state, thereby improving the accuracy of the detection.

[0049] The design of the fit between the center hole contact 323 and the bushing 324, as well as the movable setting of the center hole standard detection rod 325, ensures stable and accurate contact and measurement of the size and shape of the center hole 101 during the testing process, while avoiding testing errors caused by individual differences in components. The limiting ring 326 not only prevents excessive movement of the rod 3251 within the bushing but also ensures effective fit between the center hole contact 323 and the standard connector 3252, further improving the reliability of the test. The introduction of the compression spring 329 provides a buffering effect during the testing process, protecting the testing components from accidental impacts and ensuring the continuity and stability of the measurement.

[0050] Overall, this design not only improves the accuracy and efficiency of center hole inspection, but also enhances the adaptability and durability of the inspection system, providing a more reliable guarantee for the quality control of parts.

[0051] The center hole detection assembly 32 is configured such that when the limiting ring 326 contacts the upper end of the bushing 324, the standard connector 3252 extends a predetermined distance from the upper end face of the center hole contact 323; the lower end of the standard connector 3252 is configured to have the standard shape of the center hole 101.

[0052] This configuration ensures that the standard connector 3252 can accurately contact the center hole 101 with a predetermined extension length during center hole inspection. This design not only improves the accuracy of the inspection but also makes the inspection process more standardized and controllable. The lower end of the standard connector 3252 is designed to conform to the standard shape of the center hole 101, perfectly matching the machined standard center hole 101 under test. This effectively reduces measurement errors caused by shape mismatch and allows for rapid and accurate identification of whether the center hole meets the machining standards. Furthermore, the design of the standard connector 3252 extending a predetermined distance when the limiting ring 326 contacts the upper end of the bushing 324 also protects the inspection equipment and the tested component 101, preventing damage caused by excessive force or improper operation. This design not only improves the inspection accuracy but also enhances the safety and stability of the inspection system, providing strong support for the accurate measurement and quality control of component 100.

[0053] In this application, the helical tooth outer diameter ring gauge detection assembly 33 includes a floating head fixing plate 331 and a helical tooth outer diameter floating head 332; the floating head fixing plate 331 is slidably installed on the lower part of the upright plate 313, and the helical tooth outer diameter floating head 331 includes a helical tooth outer diameter ring gauge 3322 that is floating relative to the floating head fixing plate 331, and the helical tooth outer diameter ring gauge 332 cooperates with the threaded helical tooth 102 to detect the threaded helical tooth 102.

[0054] The helical tooth outer diameter ring gauge inspection assembly 33, through the combined design of a floating head fixing plate 331 and a helical tooth outer diameter floating head 332, achieves efficient and accurate inspection of the helical thread teeth 102. The floating head fixing plate 331 is slidably mounted on the vertical plate, providing flexible adjustment space for the inspection position, making the inspection process more flexible and convenient. The helical tooth outer diameter ring gauge 3322 in the helical tooth outer diameter floating head 332 adopts a floating setting, which can adaptively cooperate with the helical thread teeth 102, effectively reducing measurement errors caused by fit clearance or shape differences, and improving the accuracy and reliability of the inspection.

[0055] Specifically, the helical tooth outer diameter floating head 332 also includes a helical tooth ring gauge sleeve 3321, a floating tooth gauge sleeve 3323, a floating tooth gauge cable sleeve 3324, and a floating tooth gauge universal joint 3325. The floating tooth gauge sleeve 3323 is fixed to the upper end of the floating head fixing plate 331. The floating tooth gauge universal joint 3325 is disposed inside the floating tooth gauge sleeve 3323. The floating tooth gauge cable sleeve 3324 is fitted on the outside of the floating tooth gauge universal joint 3325. The helical tooth ring gauge sleeve 3323 is rotatably fitted on the outside of the floating tooth gauge cable sleeve 3324. The helical tooth outer diameter ring gauge 3322 is installed inside the mounting groove at the upper end of the helical tooth ring gauge sleeve 3321.

[0056] The above-described structural combination constructs a highly flexible and adaptable thread helical tooth detection assembly 33. The floating thread gauge sleeve 3323 is fixed to the floating head fixing plate 331, ensuring the stability of the thread helical tooth detection assembly 33. The combination of the floating thread gauge universal joint 3325 and the floating thread gauge cable sleeve 3324 provides adaptability and flexibility in the detection process, allowing the helical tooth outer diameter ring gauge 3322 to be finely adjusted according to the shape and angle of different thread helical teeth, ensuring the accuracy of the detection results.

[0057] Specifically, a bearing 3326 is fitted on the outer side of the floating thread gauge universal joint 3325. The helical tooth ring gauge sleeve 3323 and the floating thread gauge cable sleeve 3324 are located above and below the bearing 3326, respectively. The bearing 3326 reduces friction and wear, making the floating thread gauge universal joint 3325 rotate and adjust more smoothly, improving inspection efficiency and accuracy, ensuring the stability and accuracy of the helical tooth outer diameter ring gauge 3322 during inspection, and allowing the floating thread gauge universal joint 3325 to freely adjust its angle within a certain range to adapt to the inspection requirements of different thread helical teeth.

[0058] During the specific inspection, the part to be tested 100 rotates with the horizontal turntable 61 to the helical tooth outer diameter ring gauge inspection station 61d. At this time, after adjusting the verticality of the center hole standard inspection rod 325 by the XY axis adjustable slide 322, the center hole inspection assembly 32 is driven to move down as a whole, so that the center hole contact 323 contacts the end face of 110. The displacement of the center hole standard inspection rod 325 detected by the center hole sensor probe 328 at this time can determine whether the center hole of 110 meets the processing requirements.

[0059] Simultaneously, the helical tooth outer diameter ring gauge inspection assembly 33 moves upward as a whole, and the waist 130 and small end 140 of component 100 extend into the interior of the helical tooth outer diameter ring gauge 3322. Since the helical tooth ring gauge sleeve 3323 is rotatably fitted onto the outside of the floating tooth gauge cable sleeve 3324, and the helical tooth outer diameter ring gauge 3322 is installed inside the mounting groove at the upper end of the helical tooth ring gauge sleeve 3321, the helical tooth ring gauge sleeve 3323 drives the helical tooth outer diameter ring gauge 3322 to rotate during the process of the waist 130 and small end 140 extending into the interior of the helical tooth outer diameter ring gauge 3322, thereby preventing the inspection process from failing due to component jamming.

[0060] This workstation integrates the inspection of the helical tooth outer diameter ring gauge and the inspection of the center hole into one unit, thereby ensuring that the two inspection processes can be carried out simultaneously. This eliminates the need for setting up separate processes, effectively saving space occupied by the inspection equipment. The simultaneous performance of the two inspections also effectively improves inspection efficiency.

[0061] Preferably, the base 31 includes a first adjustable base plate 311, a second adjustable base plate 312, and a vertical plate 313. The first adjustable base plate 311 is movably disposed on the mounting platform 10 along a first direction, the second adjustable base plate 312 is movably disposed on the first adjustable base plate 311 along a direction, and the vertical plate 313 is vertically connected to the second adjustable base plate 312.

[0062] Specifically, the first adjustable base plate 311 has multiple strip holes along the X direction, which are movably locked onto the mounting platform 10 by locking bolts. The second adjustable base plate 312 has multiple strip holes along the Y direction, which are movably locked onto the first adjustable base plate 311 by locking bolts. This allows the upright plate 313 to be horizontally adjustable on the mounting platform 10, ensuring the accuracy of the detection position.

[0063] In this application, the worktable 20 is a circular turntable with six evenly distributed inspection stations 20d. The circular turntable 20 is configured to rotate in 60° steps. It is understood that other inspection tools can be set at other inspection stations to inspect other structures on the parts. The number of inspection stations 20d on the circular turntable can be determined according to the actual situation and can be set to three, four, six, or other selectable numbers. Correspondingly, the included angle of the stepping rotation is adjusted accordingly to be consistent with the included angle of two adjacent inspection stations 20d. After each rotation, one inspection station 20d is set to correspond to the synchronous inspection device.

[0064] In this application, in order to facilitate the fixing of the component 100 and effectively prevent the wear of the workbench 20, a mounting hole is formed on each of the inspection stations 20d, and a component carrier 200 is detachably set in the mounting hole. The carrier 200 has a positioning hole for the vertical setting of the component 100.

[0065] The simultaneous detection device for the outer diameter and center hole of helical teeth provided in this application enables the simultaneous detection of the center hole and helical threads of parts, significantly improving detection efficiency. By setting a fixed detection station for the parts on the worktable, and using the center hole detection component and the helical tooth outer diameter ring gauge detection component to detect the center hole and helical threads on both sides of the worktable in the vertical direction, the problem of needing to change stations in traditional detection methods is avoided, error introduction is reduced, and production costs are lowered. At the same time, the device has a compact structure, is easy to operate, and is highly adaptable, and can be widely used in the detection of various parts with similar structures, providing strong support for intelligent and automated detection in the manufacturing industry.

[0066] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
