Description

Technical Field

[0001] This utility model relates to the field of splined shaft sleeve testing technology, and in particular to a splined shaft sleeve paired with a steel ball sorting instrument. Background Technology

[0002] In the field of mechanical transmission, the spline shaft is a key transmission component. The accuracy of its span and spacing directly affects the equipment assembly quality and transmission performance. As industrial automation continues to increase the requirements for transmission accuracy, accurately detecting the span and spacing of the spline shaft and selecting suitable steel balls based on the detection results has become a core link to ensure the reliability of spline shaft assembly.

[0003] In the traditional process of detecting the span and spacing between spline shafts, manual measurement and positioning are often required. Manual measurement usually uses specialized measuring tools (such as micrometers and coordinate measuring machines) to measure a single section. However, single-section measurement cannot fully reflect the form and position tolerances of the bushing, is prone to missing local deformations, and is easily affected by human factors, resulting in cumbersome and inefficient operation and difficulty in ensuring the consistency of measurement accuracy. At the same time, the measurement results rely on manual recording and comparison, lacking real-time data processing capabilities. Manual positioning can easily lead to misalignment between the spline shaft and the measuring probe, and misalignment of the spline shaft clamping can easily lead to distortion of the detection data, which in turn affects the accuracy of subsequent steel ball sorting. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a splined shaft assembly with a steel ball sorting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spline shaft assembly and steel ball sorting instrument includes a worktable, an upper protective cover fixedly connected to the top of the worktable, and two detection plates symmetrically fixedly connected inside the worktable. A spline shaft measuring component and a spline sleeve measuring component are respectively provided on the two detection plates, and a positioning clamping component is provided on one side of each of the spline shaft measuring component and the spline sleeve measuring component.

[0007] The spline shaft measuring assembly includes a mounting guide located at the bottom of the detection plate. A probe washer is fixedly connected to the top of the mounting guide. Both the probe washer and the mounting guide have mounting holes in the middle for placing the spline shaft. Three sets of support seats are arranged in a circumferential array around the mounting holes. A shape-changing pad is provided on the top of the support seat. A push cylinder is provided inside one side of the shape-changing pad. The output end of the push cylinder is connected to a cross-bar displacement sensor. The output end of the cross-bar displacement sensor is connected to a calibration probe. The outer wall of the mounting guide has six movable holes for the calibration probe to pass through.

[0008] Preferably, the spline sleeve testing assembly includes a mounting plate located at the bottom of another testing plate. A reduction motor is provided on the mounting plate. The output end of the reduction motor is connected to a drive wheel. A transmission belt is sleeved on the outside of the drive wheel. One end of the transmission belt is connected to a driven wheel. The end of the driven wheel is fixedly connected to a drive shaft.

[0009] One end of the drive shaft passes through the detection plate and is connected to a positioning seat. A positioning hole is opened in the middle of the positioning seat, and a positioning rod is installed in the positioning hole. A rod spacing displacement sensor is installed on the top of the positioning rod, and two measuring probes are symmetrically connected to the output end of the rod spacing displacement sensor.

[0010] Preferably, the positioning clamping assembly includes a fixed plate located on one side of the detection plate, a positioning cylinder is provided on the top side of the fixed plate, two slide rails are fixedly connected to the outer wall of the fixed plate, a guide rail seat is slidably connected on the slide rails, and the output end of the positioning cylinder is connected to the guide rail seat.

[0011] A clamping gripper is fixedly connected to one side of the guide rail seat, and a supporting side plate is fixedly connected to the side wall of the fixing plate. Laser diameter gauges are evenly distributed on the supporting side plate, and a V-shaped clamping block is connected to the bottom of the guide rail seat on the spline sleeve measuring assembly via a T-shaped plate.

[0012] Preferably, a pad is fixedly connected between the two detection plates, and the pad is respectively provided with shaft calibration parts and sleeve calibration parts.

[0013] Preferably, a support profile is fixedly connected to the workbench, and two control switches are provided on the support profile. The two control switches are provided with a start button and an emergency stop button.

[0014] Preferably, a support beam is fixedly connected inside the upper protective cover, a display screen is installed on the support beam, electrical components are installed below the display screen, and an SPC system is installed inside the electrical components.

[0015] Preferably, two vertical plates are symmetrically arranged on the workbench, and a number of safety light curtains are fixedly connected between the two vertical plates.

[0016] Preferably, a frame is fixedly connected to one side of the workbench, and several mounting boxes are stacked on the frame.

[0017] Preferably, the side wall of the workbench is provided with heat dissipation holes, and a cooling fan is installed in the heat dissipation holes.

[0018] The beneficial effects of this utility model are:

[0019] This invention utilizes a positioning and clamping assembly consisting of a positioning cylinder, a guide rail, and a clamping gripper to achieve automated downward positioning of the spline shaft. Simultaneously, it works with a laser diameter gauge to monitor the relative position of the spline shaft and the measuring station in real time. If the positioning is abnormal, the SPC system can automatically determine and reposition the shaft, solving the problems of easy deviation and data distortion in traditional manual positioning, and ensuring the detection accuracy of the span and distance between bars.

[0020] This invention employs six cross-bar spacing displacement sensors, arranged in pairs, to simultaneously scan three sections of the spline shaft. Each section collects three sets of ball track dimension data, for a total of nine sets of data. During bar spacing detection, a geared motor drives a positioning rod to rotate, detecting multiple sections and multiple sets of internal channels of the spline shaft, also acquiring nine sets of data. The detection data is transmitted to a display screen in real time, and automatically calculated and analyzed by an SPC system. This allows for rapid comparison of measured values ​​with theoretical tolerances. Compared to traditional single-section manual measurement and recording, multi-section detection comprehensively reflects the spline shaft's form and position tolerances, avoids missing local deformations, and provides richer, more reliable detection data that accurately reflects processing quality, thus improving the efficiency and accuracy of spline shaft ball selection.

[0021] This invention protects personnel during instrument operation by using a safety light curtain in front of the upper protective cover; the cooling fan accelerates internal air circulation and dissipates heat through the heat dissipation holes, maintaining a stable internal temperature field and preventing excessive temperature from affecting detection accuracy, thus ensuring long-term stable operation of the equipment.

A push cylinder is provided inside the change-up pad 305. The output end of the push cylinder is connected to a cross-bar distance displacement sensor 306. The output end of the cross-bar distance displacement sensor 306 is connected to a calibration probe 307. The outer wall of the mounting guide 301 has six movable holes through which the calibration probe 307 can pass.

[0038] The spline sleeve testing assembly 4 includes a mounting plate 401 located at the bottom of another testing plate. A reduction motor 402 is provided on the mounting plate 401. The output end of the reduction motor 402 is connected to a drive wheel. A transmission belt 403 is sleeved on the outside of the drive wheel. One end of the transmission belt 403 is connected to a driven wheel. The end of the driven wheel is fixedly connected to a drive shaft.

[0039] One end of the drive shaft passes through the detection plate and is connected to a positioning seat 404. A positioning hole is provided in the middle of the positioning seat 404, and a positioning rod 405 is provided in the positioning hole. A rod spacing displacement sensor 406 is provided on the top of the positioning rod 405. Two measuring probes 407 are symmetrically connected to the output end of the rod spacing displacement sensor 406.

[0040] The positioning and clamping assembly includes a fixed plate 5 located on one side of the detection plate, a positioning cylinder 501 is provided on the top side of the fixed plate 5, two slide rails 502 are fixedly connected to the outer wall of the fixed plate 5, a guide rail seat 503 is slidably connected on the slide rails 502, and the output end of the positioning cylinder 501 is connected to the guide rail seat 503.

[0041] A clamping gripper 504 is fixedly connected to one side of the guide rail seat 503, and a supporting side plate 505 is fixedly connected to the side wall of the fixing plate 5. Laser diameter gauges 506 are evenly distributed on the supporting side plate 505. A V-shaped clamping block 601 is connected to the bottom of the guide rail seat 503 located on the spline sleeve measuring assembly 4 through a T-shaped plate 6.

[0042] A pad 7 is fixedly connected between the two test plates. A shaft calibration part 701 and a sleeve calibration part 702 are respectively provided on the pad 7.

[0043] A support profile is fixedly connected to the workbench 1. Two control switches 8 are installed on the support profile. The two control switches 8 are equipped with a start button and an emergency stop button.

[0044] The upper protective cover 2 is internally fixedly connected to a support beam 9, on which a display screen 901 is installed. Below the display screen 901, an electrical component 902 is installed, and an SPC system is installed inside the electrical component 902.

[0045] Two vertical plates 10 are symmetrically arranged on the workbench 1, and several safety light curtains 100 are fixedly connected between the two vertical plates 10.

[0046] A frame 11 is fixedly connected to one side of the workbench 1, and several storage boxes 110 are stacked on the frame 11.

[0047] The side wall of the workbench 1 is provided with heat dissipation holes 12, and a cooling fan is installed inside the heat dissipation holes 12.

[0048] In this implementation scheme, when it is necessary to sequentially test the span and spacing of the spline shaft, firstly, the shaft calibration part 701 is placed on the probe washer on the mounting guide 301, and the calibration part 702 is fitted onto the outside of the positioning rod 405 for zeroing. After zeroing, the spline shaft to be tested is placed in the clamping jaw 504, so that the clamping jaw 504 clamps the spline shaft. Then, the two positioning cylinders 501 are activated in sequence. When the positioning cylinders 501 are running, they drive the guide rail 503 to move downward along the track of the slide rail 502. The downward movement of the guide rail 503 drives the clamping jaw 504 to move downward. Thus, when the clamping jaw 504 moves downward, it drives the bottom of the spline shaft into the spline shaft measuring assembly 3. Inside the mounting hole 303 and on the positioning rod 405 on the spline sleeve measuring assembly 4, the guide rail seat 503 moves while driving the V-shaped clamp 601 to move downward, thereby clamping the contact part between the spline shaft and the positioning rod 405. During the downward positioning of the spline shaft, the laser diameter gauges 506, which are evenly distributed on one side, scan the cross-sectional position of the spline shaft to synchronously monitor the relative position between the spline shaft and the measuring station. If the spline shaft does not fall precisely into the mounting hole 303 and the positioning rod 405, the distance data collected by the laser diameter gauge 506 will deviate from the theoretical value. Subsequently, the SPC system can determine the positioning abnormality based on this and reposition it, thereby ensuring the stability during the production process of the spline shaft and preventing the deviation from affecting the detection accuracy.

[0049] Furthermore, when it is necessary to detect the span of the spline shaft, six span displacement sensors 306 are activated in pairs. When the span displacement sensors 306 are running, the calibration probe 307 scans and detects the three sections of the spline shaft in sequence. Three sets of ball track size data are detected on each section. Then, three sections are detected, for a total of 9 sets of data. By comparing with the theoretical value, the machining quality of the spline shaft is indirectly reflected.

[0050] When detecting the bar spacing of the spline shaft, the positioning rod 405 is inserted into the spline shaft. At this time, the bar spacing displacement sensor 406 is activated, and the measuring probe 407 is used to detect three cross-sections of the internal channels of the spline shaft. After the three cross-sections are detected, the reduction motor 402 is activated. When the reduction motor 402 runs, it drives the drive wheel to rotate. When the drive wheel rotates, it drives one end of the transmission belt 403 to rotate. When one end of the transmission belt 403 rotates, it drives the other end to drive the driven wheel. When the driven wheel rotates, it drives the positioning seat 404 to rotate. When the positioning seat 404 rotates, it drives the positioning rod 405 to rotate. When the positioning rod 405 drives the bar spacing displacement sensor 406 and the measuring probe 407 to rotate 60°, another set of channels inside the spline shaft is detected. This cycle of detection is repeated to detect three cross-sections and obtain 9 sets of data.

[0051] Furthermore, after the spline shaft's span and spacing are tested, the test data is transmitted to the display screen 901. The SPC system inside the electrical component 902 calculates and analyzes the measurement results. By comparing the measured span and spacing with the design theoretical value (or tolerance range), if they are within the tolerance, the spline shaft's span and spacing are deemed qualified. The spline shaft can then be manually removed and placed in the storage box 110 for unified storage and management for subsequent assembly. If the values ​​are out of tolerance, the cause is analyzed, and the spline shaft is subsequently reworked or scrapped.

[0052] When detecting the span and spacing of the spline shaft, the safety light curtain 100 in front of the upper protective cover 2 prevents the spread of heat and protects personnel safety during the operation of the instrument. The cooling fan accelerates the internal air circulation and exhausts the heat generated inside the instrument through the heat dissipation hole 12 to prevent the detection accuracy of the span and spacing from being affected by excessive temperature and to maintain the stability of the internal temperature field.
