Description

Technical Field

[0001] The invention relates to the technical field of parts production and testing equipment, and in particular to a synchronous detection device for the outer diameter and center hole of a helical gear. Background Art

[0002] In the machinery manufacturing industry, the precision and quality of parts are directly related to the performance and reliability of the final product. For a specific designed part, its structural features include a center hole set at one end and a thread bevel formed near the outside of the other end. These two features each have different functions. The center hole is often used for installation and positioning, requiring extremely high coaxiality and dimensional accuracy to ensure the stable operation of rotating parts and reduce wear. The thread bevel is usually used for close connection with other parts or to transmit torque. The accuracy of its pitch, tooth angle, thread depth and other parameters is crucial to the connection strength and sealing.

[0003] In the traditional final inspection process, since these two features are relatively independent in spatial position, and the detection methods and required equipment are different, they are usually carried out separately at two different stations. The detection of the center hole relies on a high-precision inner diameter gauge to ensure that the position accuracy and size of the hole meet the design requirements. The detection of the helical thread is more complicated, requiring the use of a special thread comprehensive measuring instrument or thread plug gauge to verify whether the various parameters of the thread meet the standards through rotary contact measurement or optical non-contact scanning technology.

[0004] Although this multi-station inspection method can ensure inspection accuracy, it has the problems of low production efficiency and increased costs. Each time the station is changed, the parts need to be repositioned, which is not only time-consuming, but may also introduce new errors due to multiple clamping. In addition, multi-station inspection requires more equipment and manpower investment, increasing the overall production cost and management complexity.

[0005] Therefore, as the manufacturing industry develops towards intelligence and automation, how to optimize the inspection process and improve inspection efficiency has become an urgent problem to be solved. Especially in the face of large-scale production models, developing a device that can simultaneously detect the center hole and the helical thread teeth can not only significantly improve the inspection speed and reduce production costs, but also enhance the flexibility and adaptability of the production line, which is of great significance to improving the competitiveness of the entire manufacturing process and product quality.

[0025] A synchronous detection device for the outer diameter and center hole of a helical gear, such as Figure 1 As shown, it is used to detect a component 100 with a predetermined structure, wherein the predetermined structure at least includes a center hole 101 located at one end of the component 100 and a threaded bevel tooth 102 on the outer side surface close to the other end of the component 100.

[0026] like Figure 2-6 As shown, it includes a mounting platform 10, a workbench 20, a base 31, a center hole detection component 32 and a helical gear outer diameter ring gauge detection component 33.

[0027] The base 31 is fixed to the mounting platform 10 and includes a vertically arranged stand 313; The workbench 20 is horizontally arranged above the mounting platform 10, and an inspection station 20d for fixing the component 100 is arranged on the workbench 20. When the component 100 is fixed at the inspection station, the center hole 101 and the threaded bevel teeth 102 are respectively located on both sides of the vertical direction of the workbench 20; in an embodiment of the present application, the center hole 101 is located at the upper end of the component 100, and when fixed at the inspection station, it is located above the table surface of the workbench 20, and the threaded bevel teeth 102 are located on the outside of the lower side of the component 100, and when fixed at the inspection station, it is located below the table surface of the workbench 20.

[0028] The center hole detection assembly 32 and the helical gear outer diameter ring gauge detection assembly 33 are both vertically slidably arranged on the vertical plate, and the detection station 20d is located between the center hole detection assembly 32 and the helical gear outer diameter ring gauge detection assembly 33. The center hole detection assembly 32 is used to detect the center hole 101; the helical gear outer diameter ring gauge detection assembly 33 is used to detect the threaded helical teeth 102.

[0029] In an optional embodiment of the present application, the center hole detection assembly 32 is vertically slidably installed on the upper part of the vertical plate 313, and is used to detect the center hole 101 of the component 100 to be tested; the helical tooth outer diameter ring gauge detection assembly 33 is vertically slidably installed on the lower part of the vertical plate 313, and is used to detect the threaded helical teeth 102 of the component 100 to be tested.

[0030] Among them, the center hole detection component 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.

[0031] The L plate 321 is slidably mounted on the upper part of the vertical plate 313 and is formed with a through hole. The XY axis adjustable slide 322 is installed on the upper end of the L plate. The bushing 324 passes through the L plate 321 and the XY axis adjustable slide 322 and is fixed to the upper end of the XY axis adjustable slide 322.

[0032] Among them, the center hole contact 323 is fixed to the lower end of the bushing 324, the center hole standard detection rod 325 includes a rod body 3251 and a standard joint 3252, the rod body 3251 is movably arranged in the bushing 3252, and a through hole matching the standard joint 3252 is formed on the center hole contact 323, the limiting ring 326 is connected to the outer side of the rod body 3251 and is arranged at the upper end of the bushing 324, and the outer diameter of the limiting ring 326 is larger than the inner diameter of the bushing 324.

[0033] 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 limit ring 326 and the probe fixing L plate 327.

[0034] By introducing structures such as L-plate 321, XY-axis adjustable slide 322, center hole contact 323, bushing 324, center hole standard detection rod 325, limit ring 326, probe fixing L-plate 327, center hole sensor probe 328 and compression spring 329, a center hole detection assembly 32 with adjustable height and accurate coaxiality calibration is constructed. Among them, the sliding installation of L-plate 321 on the vertical plate 313 provides flexibility in the detection position, and 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.

[0035] Among them, the matching design of the center hole contact 323 and the bushing 324, as well as the movable setting of the center hole standard detection rod 325, enable the detection process to stably and accurately contact and measure the size and shape of the center hole 101, while avoiding detection errors caused by individual differences in parts. The setting of the limit ring 326 not only prevents excessive movement of the rod body 3251 in the bushing, but also ensures the effective matching of the center hole contact 323 and the standard connector 3252, further improving the reliability of the detection; the introduction of the compression spring 329 provides a buffering effect during the detection process, which not only protects the detection component from accidental impact, but also ensures the continuity and stability of the measurement.

[0036] Overall, this design not only improves the accuracy and efficiency of center hole detection, but also enhances the adaptability and durability of the detection system, providing a more reliable guarantee for the quality control of parts.

[0037] The center hole detection assembly 32 is configured so that when the limit ring 326 contacts the upper end of the bushing 324 , the standard connector 3252 extends a predetermined distance from the upper end surface of the center hole contact 323 ; the lower end of the standard connector 3252 is configured to be the standard shape of the center hole 101 .

[0038] This configuration ensures that when the center hole is detected, the standard connector 3252 can accurately contact the center hole 101 with a predetermined extension length. This design not only improves the accuracy of the detection, but also makes the detection process more standardized and controllable. The lower end of the standard connector 3252 is designed to be the standard shape of the center hole 101, which can perfectly match the center hole 101 to be measured according to the processing standard, thereby effectively reducing the measurement error caused by shape mismatch, and can quickly and accurately identify whether the center hole meets the processing standard. In addition, when the limit ring 326 contacts the upper end of the bushing 324, the design of the standard connector 3252 extending a predetermined distance also plays a role in protecting the detection equipment and the component 101 to be measured, avoiding damage caused by excessive force or improper operation. This design not only improves the detection accuracy, but also enhances the safety and stability of the detection system, providing strong support for the accurate measurement and quality control of the component 100.

[0039] In the present application, the helical gear outer diameter ring gauge detection assembly 33 includes a floating head fixing plate 331 and a helical gear outer diameter floating head 332; the floating head fixing plate 331 is slidably installed on the lower part of the vertical plate 313, and the helical gear outer diameter floating head 331 includes a helical gear outer diameter ring gauge 3322 floatingly set relative to the floating head fixing plate 331, and the helical gear outer diameter ring gauge 332 cooperates with the threaded helical teeth 102 to detect the threaded helical teeth 102.

[0040] The helical gear outer diameter ring gauge detection assembly 33 realizes efficient and accurate detection of the threaded helical gear 102 through the combined design of the floating head fixing plate 331 and the helical gear outer diameter floating head 332. The floating head fixing plate 331 is slidably mounted on the vertical plate, providing a flexible detection position adjustment space, making the detection process more flexible and convenient. The helical gear outer diameter ring gauge 3322 in the helical gear outer diameter floating head 332 adopts a floating setting, which can adaptively cooperate with the threaded helical gear 102, effectively reducing the measurement error caused by the matching clearance or shape difference, and improving the accuracy and reliability of the detection.

[0041] Specifically, the helical gear outer diameter floating head 332 also includes a helical gear ring gauge sleeve 3321, a floating gauge sleeve 3323, a floating gauge cable sleeve 3324 and a floating gauge universal joint 3325. The floating gauge sleeve 3323 is fixed to the upper end of the floating head fixed plate 331, the floating gauge universal joint 3325 is arranged inside the floating gauge sleeve 3323, the floating gauge cable sleeve 3324 is mounted on the outside of the floating gauge universal joint 3325, the helical gear ring gauge sleeve 3323 can be rotatably mounted on the outside of the floating gauge cable sleeve 3324, and the helical gear outer diameter ring gauge 3322 is installed inside the mounting groove at the upper end of the helical gear ring gauge sleeve 3321.

[0042] The above structural combination constructs a highly flexible and adaptable thread bevel gear detection assembly 33. The floating gauge sleeve 3323 is fixed to the floating head fixing plate 331, ensuring the stability of the thread bevel gear detection assembly 33, while the combination of the floating gauge universal joint 3325 and the floating gauge cable sleeve 3324 provides adaptability and flexibility during the detection process, so that the bevel gear outer diameter ring gauge 3322 can be fine-tuned according to the shape and angle of different thread bevel gears, ensuring the accuracy of the detection results.

[0043] Specifically, a bearing 3326 is sleeved on the outer side of the floating tooth gauge universal joint 3325, and the helical gear ring gauge sleeve 3323 and the floating tooth gauge cable rod sleeve 3324 are respectively located on the upper side and the lower side of the bearing 3326. The bearing 3326 can reduce friction and wear, so that the floating tooth gauge universal joint 3325 is smoother during the rotation and adjustment process, improves the detection efficiency and accuracy, ensures the stability and accuracy of the helical gear outer diameter ring gauge 3322 during the detection process, and enables the floating tooth gauge universal joint 3325 to freely adjust the angle within a certain range to meet the detection requirements of different thread helical teeth.

[0044] During specific inspection, the component 100 to be tested is rotated with the horizontal turntable 61 to the bevel gear outer diameter ring gauge inspection station 61d. At this time, after adjusting the verticality of the center hole standard inspection rod 325 through the XY axis adjustable slide 322, the center hole detection assembly 32 is driven to move downward as a whole, so that the center hole contact 323 contacts the end face of 110. At this time, the displacement of the center hole standard inspection rod 325 detected by the center hole sensor probe 328 can determine whether the center hole 110 meets the processing requirements.

[0045] At the same time, the helical outer diameter ring gauge detection assembly 33 moves upward as a whole, and the waist 130 and the small head 140 of the component 100 extend into the interior of the helical outer diameter ring gauge 3322. Since the helical ring gauge sleeve 3323 is rotatably mounted on the outside of the floating gauge rod sleeve 3324, the helical outer diameter ring gauge 3322 is installed in the mounting groove at the upper end of the helical ring gauge sleeve 3321. Therefore, when the waist 130 and the small head 140 extend into the interior of the helical outer diameter ring gauge 3322, the helical ring gauge sleeve 3323 drives the helical outer diameter ring gauge 3322 to rotate, thereby preventing the detection process from failing due to part jamming.

[0046] At this workstation, the helical gear outer diameter ring gauge inspection and the center hole inspection are all integrated into one, thereby ensuring that the two inspection processes are carried out at the same time, eliminating the need to set up additional processes, effectively saving the space occupied by the inspection equipment, and carrying out the two inspections at the same time can also effectively improve the inspection efficiency.

[0047] Preferably, the base 31 includes a first adjustable bottom plate 311, a second adjustable bottom plate 312 and a vertical plate 313, the first adjustable bottom plate 311 is movably arranged on the working platform 10 along a first direction, the second adjustable bottom plate 312 is movably arranged on the first adjustable bottom plate 311 along a direction, and the vertical plate 313 is vertically connected to the second adjustable bottom plate 312.

[0048] Specifically, a plurality of strip holes along the X direction are formed on the first adjustable base plate 311, which is movably locked on the working platform 10 by locking bolts, and a plurality of strip holes along the Y direction are formed on the second adjustable base plate 312, which is movably locked on the first adjustable base plate 311 by locking bolts, thereby realizing horizontal adjustment of the vertical plate 313 on the working platform 10 to ensure the accuracy of the detection position.

[0049] In the present application, the working platform 20 is a circular turntable, on which 6 evenly distributed inspection stations 20d are arranged. The circular turntable 20 is configured to rotate in steps of 60°. It can be understood that other inspection tools can be set at other inspection stations to realize the inspection of other structures on parts. The number of inspection stations 20d on the circular turntable can be determined according to actual conditions, and can be set to 3, 4, 6 or other optional numbers. Correspondingly, the angle of the step-by-step rotation is adjusted accordingly to be consistent with the angle between two adjacent inspection stations 20d, and after each rotation, there is an inspection station 20d corresponding to the synchronous detection device setting.

[0050] In the present application, in order to facilitate the fixation of the component 100 and effectively prevent the wear of the work platform 20, a mounting hole is formed on each of the inspection stations 20d, and a component carrier 200 is detachably arranged in the mounting hole. A positioning hole is formed on the carrier 200 for the vertical setting of the component 100.

[0051] The synchronous detection device for the outer diameter and center hole of the helical gear provided by the present application realizes the simultaneous detection of the center hole and the helical threaded gear of the parts, which significantly improves the detection efficiency. By setting a detection station for fixing the parts on the workbench, and using the center hole detection component and the helical gear outer diameter ring gauge detection component to detect the center hole and the helical threaded gear on both sides of the vertical direction of the workbench, the problem of changing the station in the traditional detection method is avoided, the introduction of errors is reduced, and the production cost is reduced. At the same time, the device has a compact structure, is easy to operate, and has strong adaptability. It can be widely used in the detection of various parts with similar structures, providing strong support for the intelligent and automated detection of the manufacturing industry.
