[0002] As a key component in mechanical transmission systems such as automobiles, the ball cage plays an important role in ensuring the stability and accuracy of transmission. It is usually a ring-shaped structure with many windows distributed around it. These windows are used to accurately position and guide the transmission ball to ensure smooth transmission of power.

[0003] In the traditional production inspection process, the width inspection of the numerous windows around the ball cage cage mostly relies on manual operation. The inspectors need to use measuring tools to measure each window one by one. The process is cumbersome and easily prone to errors due to human factors. The inspection efficiency is extremely low and it is difficult to meet the inspection needs of large-scale production. At the same time, the inner and outer diameter inspections of the ball cage cage are also mainly manual. Manual handheld measuring tools are not only labor-intensive, but also affected by factors such as human operation techniques and measurement angles.

[0017] The following is combined with the embodiments and attached Figures 1 to 13 , the technical solution of the present invention is further elaborated. Example

[0018] A ball cage cage comprehensive detection device comprises: a box body 1, an inner and outer diameter detection module 2, a window detection module 3 and a transfer module 4 arranged inside the box body 1, and three groups of conveying modules 5; The transfer module 4 on the left transfers the workpiece on the conveying module 5 on the left to the left inspection table 21 of the inner and outer diameter inspection module 2 for inner and outer diameter inspection, and after completion, transfers the workpiece to the conveying module 5 in the middle; The transfer module 4 on the right transfers the workpiece on the conveying module 5 in the middle to the right inspection station 31 of the window inspection module 3 for window inspection, and then transfers it to the conveying module 5 on the right after the inspection is completed; The inner and outer diameter detection module 2 includes an outer diameter detection sensor assembly 22 and an inner diameter detection sensor assembly 23. The two sets of outer diameter detection sensor assemblies 22 are synchronously moved inward to contact the outer wall of the workpiece under the action of the power assembly 1 24 to measure the outer diameter of the workpiece. The two sets of inner diameter detection sensor assemblies 23 are synchronously moved outward to contact the inner wall of the workpiece under the action of the power assembly 2 25 to measure the inner diameter of the workpiece. The window detection module 3 includes an umbrella linkage component 32 and a plurality of groups of window detection sensor modules 33. The umbrella linkage component 32 drives each window detection sensor module 33 to simultaneously extend into the corresponding window of the workpiece on the right detection platform 31 to measure the width of the workpiece window.

[0019] like Figure 1 to Figure 13 As shown, the use principle of the present invention is: This comprehensive detection device is mainly composed of a box body, an inner and outer diameter detection module arranged inside the box body, a window detection module and a transfer module, as well as three groups of conveying modules. The transfer module on the left is responsible for transferring the workpiece on the left conveying module to the left detection station of the inner and outer diameter detection module for inner and outer diameter detection, and then transferring it to the middle conveying module after completion; the transfer module on the right transfers the workpiece on the middle conveying module to the right detection station of the window detection module for window detection, and then transfers it to the right conveying module after completion. The inner and outer diameter detection module drives the outer diameter detection sensor assembly and the inner diameter detection sensor assembly through the power assembly to measure the outer diameter and inner diameter of the workpiece at the same time; the window detection module uses an umbrella linkage assembly to drive several groups of window detection sensor modules, and simultaneously extends into each window corresponding to the workpiece to measure the window width.

[0020] It realizes the automatic detection of the inner and outer diameters of the ball cage cage and the window width, greatly improves the detection efficiency, reduces the errors caused by manual detection, ensures the accuracy and consistency of the detection results, and effectively improves product quality and production efficiency.

[0021] As a further preferred embodiment, the power assembly 24 is located above the left inspection platform 21 and includes a guide rail 241, a slider 242 and an outer diameter cylinder 243. The slider 242 is slidably arranged on the guide rail 241. The outer diameter shift block 244 connected to the output end of the outer diameter cylinder 243 is connected to the slider 242. The outer diameter detection sensor assembly 22 includes an outer diameter mounting plate 221 and a plurality of groups of outer diameter detection sensors 222. The outer diameter mounting plate 221 is connected to the slider 242. The outer diameter detection sensors 222 are fixed on the outer diameter mounting plate 221 at intervals. The outer diameter detection sensors 222 are located outside the workpiece. A limiting screw 223 is provided at the rear end of the outer diameter mounting plate 221. The power assembly 1 is located above the left inspection table, and is composed of a guide rail 4, a slider 4 and an outer diameter cylinder. When the outer diameter cylinder is working, its output end extends or retracts, driving the outer diameter shift block connected thereto to move. Since the outer diameter shift block is connected to the slider 4, and the slider 4 is slidably set on the guide rail 4, the movement of the outer diameter shift block will cause the slider 4 to make a linear reciprocating motion along the guide rail 4. The outer diameter mounting plate connected to the slider 4 moves synchronously therewith, and several groups of outer diameter detection sensors fixed at intervals on the mounting plate can synchronously approach or move away from the outer wall of the workpiece to measure the outer diameter of the workpiece. A limit screw 1 is provided at the rear end of the outer diameter mounting plate. When the outer diameter mounting plate moves to a certain position, the limit screw 1 contacts the corresponding structure inside the box body to prevent the outer diameter mounting plate from continuing to move, thereby playing a limiting role and ensuring that the sensor will not be damaged due to excessive movement.

[0022] The power component 25 is located below the left inspection platform 21 and includes a guide rail 5 251, a slider 5 252 and an inner diameter cylinder 253. The slider 5 252 is slidably set on the guide rail 5 251. The inner diameter shift block 254 connected to the output end of the inner diameter cylinder 253 is connected to the slider 5 252. The inner diameter detection sensor component 23 includes an inner diameter mounting plate 231 and a plurality of groups of inner diameter detection sensors 232. The inner diameter mounting plate 231 is connected to the slider 5 252. The inner diameter detection sensors 232 are fixed on the inner diameter mounting plate 231 at intervals and pass upward to the top of the left inspection platform 21. The inner diameter detection sensor 232 is located inside the workpiece. A limiting screw 233 is provided at the rear end of the inner diameter mounting plate 231.

[0023] Power assembly 2 is located below the left inspection table, and its structure is similar to that of power assembly 1. Guide rail 5, slider 5 and inner diameter cylinder work together. The inner diameter cylinder drives slider 5 to slide on guide rail 5 through the inner diameter shift block, so that the inner diameter mounting plate connected to slider 5 and the inner diameter detection sensor fixed thereon pass upward through the left inspection table and contact the inner wall of the workpiece to measure the inner diameter. A limit screw 2 is also provided at the rear end of the inner diameter mounting plate to limit excessive movement of the inner diameter mounting plate.

[0024] The above structure makes the movement of the outer diameter and inner diameter detection sensors smoother and more accurate. The guide rail provides a stable guide for the movement of the slider, and the cylinder can provide a stable and controllable driving force, ensuring that the sensor can accurately contact the inner and outer walls of the workpiece for measurement, thereby improving the accuracy of the measurement. At the same time, the setting of the limit screw effectively prevents the sensor from being damaged by excessive movement, ensures the stability and reliability of the detection process, extends the service life of the detection equipment, and reduces the equipment maintenance cost.

[0025] As a further preferred embodiment, the umbrella-shaped linkage assembly 32 includes a motor 34 and several groups of connecting rod modules 35. Several groups of pull rods 341 are fixed to the bottom of the right detection platform 31, and a motor flange seat 342 is fixed to the bottom of the pull rod 341. The lower end of the motor flange seat 342 is connected to a motor fixing seat 344 through a motor pull rod 343. The motor 34 is installed on the motor fixing seat 344. The output end of the motor 34 is connected to a screw rod 345 through a connecting component. The top of the screw rod 345 is connected to a screw rod fixing plate 346, and the screw rod 345 is connected to a ball screw The female pair 347, the outer side of the ball nut pair 347 is fixed with a connecting block 348, the connecting rod module 35 includes a driving connecting rod 351, a driving connecting block 352, a guide rail 353 and a slider 354, the lower end of the driving connecting rod 351 is rotatably connected to the outer side of the connecting block 348, the lower end of the driving connecting block 352 is rotatably connected to the upper end of the driving connecting rod 351, the driving connecting block 352 passes through the right detection platform 31 and the upper end is rotatably connected to the slider 354, the slider 354 is slidably set on the guide rail 353, and the guide rail 353 is fixed to the right detection platform 31; The motor in the umbrella linkage assembly is installed on the motor fixing seat, which is connected to the motor flange seat through the motor tie rod. The motor flange seat is fixed to the tie rod at the bottom of the right test bench to ensure that the motor is installed firmly. When the motor is running, its output end drives the screw to rotate through the connecting parts. A screw fixing plate is connected to the top of the screw to fix the screw and ensure the stability of the screw during rotation. The ball nut pair on the screw will move up and down with the rotation of the screw. Since a connecting block is fixed on the outside of the ball nut pair, the connecting block will also move up and down synchronously.

[0026] The lower end of the driving connecting rod in the connecting rod module is rotatably connected to the outer side of the connecting block. When the connecting block moves up and down, the driving connecting rod will swing in a circle around the connection point with the connecting block. The upper end of the driving connecting rod is rotatably connected to the driving connecting block. The driving connecting block passes through the right detection platform and the upper end is rotatably connected to the slider three. The slider three is slidably set on the guide rail three fixed to the right detection platform. In this way, the swing of the driving connecting rod will drive the driving connecting block to slide on the guide rail three, thereby causing the window detection sensor module fixed on the slider three to move synchronously.

[0027] The window detection sensor module 33 includes an upper window detection sensor 331, a lower window detection sensor 332 and a mounting seat assembly 333. The mounting seat assembly 333 includes a mounting seat 334, a vertical slide rail 335 and an adjusting screw 2 336. The mounting seat 334 is fixed on a slider 354, and the vertical slide rail 335 is fixed on the mounting seat 334. The upper window detection sensor 331 and the lower window detection sensor 332 are respectively slidably set on the corresponding vertical slide rail 335. The upper window detection sensor 331 and the lower window detection sensor 332 are staggered up and down. The adjusting screw 2 336 is set on the vertical slide rail 335. The height of the upper window detection sensor or the lower window detection sensor is adjusted by the corresponding adjusting screw 2 336. The outer sides of the upper window detection sensor 331 and the lower window detection sensor 332 are both provided with elastic detection contacts 337.

[0028] The window detection sensor module is composed of an upper window detection sensor, a lower window detection sensor and a mounting seat assembly. The mounting seat assembly includes a mounting seat, a vertical slide rail and an adjusting screw rod 2. The mounting seat is fixed on a slider 3 and moves with the slider 3. The upper window detection sensor and the lower window detection sensor are respectively slidably set on the corresponding vertical slide rails. The height position of the sensor on the vertical slide rail can be adjusted by adjusting the screw rod 2 to adapt to the height of the ball cage holder window of different specifications. An elastic detection contact is provided on the outside of the sensor. During detection, the elastic detection contact contacts the edge of the window and uses its elastic deformation to feedback the window width information.

[0029] The umbrella-shaped linkage assembly can achieve synchronous and precise driving of multiple sets of window detection sensor modules. The precise control of the motor makes the screw rotate stably, thereby ensuring the accuracy of the movement of the window detection sensor module. At the same time, the sensor height can be flexibly adjusted by adjusting the screw rod according to different specifications of the ball cage holder, which greatly improves the versatility and adaptability of the detection device. The elastic detection contact avoids damage to the workpiece while ensuring the accuracy of the detection, improves the reliability of the detection results, reduces the possibility of defects such as scratches on the workpiece surface caused by the detection operation, and ensures product quality.

[0030] As a further preferred embodiment, an inner ball reference bowl 211 for positioning the workpiece is fixed at the center upper end of the left detection table 21, photoelectric switches 212 are arranged on both sides of the inner ball reference bowl 211, side through grooves 213 for the outer diameter detection sensor 222 to enter and exit are arranged around the inner ball reference bowl 211, and a bottom through groove 214 for the inner diameter detection sensor 232 to enter and exit is arranged at the bottom of the inner ball reference bowl 211; The inner ball reference bowl at the center upper end of the left inspection table is used to accurately locate the workpiece. The ball cage holder has a specific spherical structure, and the shape of the inner ball reference bowl is adapted to it, which enables the workpiece to be placed on the left inspection table in the correct posture, facilitating the measurement of the inner and outer diameter detection sensors. The photoelectric switches on both sides detect whether the workpiece is in place by emitting and receiving light. When the workpiece is placed on the inner ball reference bowl, it will block the light of the photoelectric switch 1, causing it to generate a signal change. After receiving the signal, the system determines that the workpiece is in place and can proceed to the next detection operation.

[0031] A reference positioning block 311 for positioning the workpiece is fixed at the center upper end of the right detection platform 31 , and photoelectric switches 312 are arranged on both sides of the reference positioning block 311 .

[0032] The reference positioning block at the center upper end of the right inspection table is used to position the workpiece during window inspection. The shape and size of the reference positioning block match the specific part of the ball cage holder, which can accurately define the position of the workpiece on the right inspection table. The photoelectric switch 2 on both sides also detects whether the workpiece is in place by blocking and conducting light. The principle is the same as that of the photoelectric switch 1 on the left inspection table.

[0033] The inner ball reference bowl and reference positioning block ensure the correct position of the workpiece during the inspection process, providing a basis for accurate measurement. Accurate positioning enables the detection sensor to contact the workpiece at the predetermined position, ensuring the accuracy and consistency of the measurement data. The setting of the photoelectric switch realizes the detection of the workpiece in place in the automated inspection process without manual intervention, further improving the inspection efficiency, reducing the errors that may be caused by manual judgment, and improving the automation and stability of the entire inspection process.

[0034] As a further preferred embodiment, the transfer module 4 also includes an X-axis linear module 41, a guide mounting plate 42, a lifting cylinder 43, a guide rail assembly 44, a grabbing mounting plate 45, a left clamping jaw assembly 46 and a right clamping jaw assembly 47.

By rotating the adjusting screw 1, slider 1 can be moved left and right on guide rail 1, thereby adjusting the position of the positioning fork installed on the left end of slider 1. The workpiece positioning groove in the positioning fork is used to accurately locate the workpiece position. The fine-tuning assembly includes a linear motor assembly, a slider 2, guide rail 2 and a connecting frame. The connecting frame connects guide rail 1 and slider 2, slider 2 is slidably set on guide rail 1, and the rear end of slider 2 is connected to the linear motor assembly. When the linear motor assembly is working, the position of slider 2 on guide rail 1 can be accurately controlled, and then the position of the positioning fork can be fine-tuned to meet higher precision positioning requirements.

[0046] The conveying module realizes the stable conveying of workpieces. The power component provides stable driving force to ensure the uniform speed of the conveyor belt, so that the workpiece can be smoothly transmitted.
