Technical Field

[0001] This utility model relates to the field of precision measurement technology, specifically to a ball bearing slider accuracy grade measuring device. Background Technology

[0002] As is well known, existing testing equipment suffers from numerous technical shortcomings in the process of ball slider precision testing: low measurement efficiency, cumbersome and time-consuming testing procedures, high skill requirements for operators, and measurement results easily affected by human factors, resulting in poor stability; insufficient measurement accuracy, with existing equipment unable to accurately capture the actual data of key dimensions of the ball slider, failing to meet the needs of high-precision testing; poor equipment versatility, difficult to adapt to different specifications and series of ball sliders, requiring complex adjustments when changing the test object, and weak adaptability; low degree of automation, unable to achieve automatic operation of the testing process, and weak data processing capabilities, unable to quickly and accurately complete data analysis and accuracy level determination. These problems not only affect the overall efficiency of ball slider precision testing but also restrict the effective control of product quality, ultimately failing to meet the high-efficiency and accurate requirements for ball slider precision testing in actual production. Therefore, there is an urgent need for a ball slider precision level measuring device that can solve the above problems. Utility Model Content

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a ball slider accuracy grade measuring device.

[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a ball bearing slider precision grade measuring device, comprising a central control mechanism and multiple actuators. Each actuator is equipped with a worktable, a slide rail, an electric push rod, and a U-shaped frame. A manual trolley is mounted on the slide rail. The central control mechanism is connected to each actuator via a quick-connect interface. The U-shaped frame is equipped with six sets of high-precision contact displacement sensors and a temperature sensor. A proximity sensor is mounted on the electric push rod. The central control mechanism is equipped with a start button and an industrial control computer, which is used to switch the test program corresponding to the actuator.

[0005] Furthermore, the quick-connect interface between the central control unit and the actuator is achieved through a heavy-duty connector plug.

[0006] Furthermore, the six sets of high-precision contact displacement sensors are used to detect the actual measured values ​​of the test piece and the standard piece in key dimensions such as parallelism, straightness, width, and height, and to assist in calculating the relative difference between the two to determine the accuracy level of the slider.

[0007] Furthermore, the workbench is made of marble measuring platform to provide a stable bearing reference for the testing process.

[0008] (III) Beneficial Effects Compared with the prior art, this utility model provides a ball slider accuracy grade measuring device, which has the following beneficial effects: This ball bearing slider accuracy level measuring device adopts a structure in which a central control mechanism and multiple sets of actuators are connected by a quick-connect interface. With the help of an industrial control computer, the test program of the corresponding actuator can be directly switched, which greatly simplifies the changeover and debugging process when testing sliders of different specifications or series, reduces test preparation time, effectively improves measurement efficiency, and avoids the problems of cumbersome operation and long time consumption of existing equipment.

[0009] The actuator's U-shaped frame is equipped with a high-precision contact displacement sensor, which can accurately collect the actual measurement values ​​of the test piece and the standard piece in key dimensions, providing accurate data support for accuracy judgment. At the same time, the actuator's worktable uses a marble measuring platform with stable load-bearing capacity, providing a stable benchmark for the entire testing process. This effectively avoids the interference of environmental factors or benchmark instability on the measurement results, significantly improving measurement accuracy. Moreover, the measurement results do not rely on manual readings, reducing the influence of human factors and making the results more objective and reliable.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1 to 4This utility model relates to a ball bearing slider precision grade measuring device, comprising a central control mechanism 1 and multiple actuators 4. Each actuator 4 is equipped with a worktable 3, a slide rail 5, an electric push rod 9, and a U-shaped frame 7. A manual trolley 2 is mounted on the slide rail 5. The central control mechanism 1 is connected to each actuator 4 via a quick-connect interface. The U-shaped frame 7 is equipped with six sets of high-precision contact displacement sensors 8 and a temperature sensor 6. The electric push rod 9 is equipped with a proximity sensor 10. The central control mechanism 1 is equipped with a start button and an industrial control computer, which is used to switch the test program corresponding to each actuator 4. In this embodiment, after confirming that the central control unit 1 and the actuator 4 to be used have been connected via quick-connect, the industrial control computer on the central control unit 1 switches to the test program corresponding to the actuator 4. A known high-precision standard part is placed at the designated reference position on the worktable 3 of the actuator 4 to ensure stable positioning of the standard part. The status of the slide rail 5, electric push rod 9, U-shaped frame 7 on the worktable 3, and the six sets of high-precision contact displacement sensors 8, temperature sensors 6, and proximity sensors 10 on the electric push rod 9 on the U-shaped frame 7 are checked to ensure that each component is working properly. The test piece (the ball bearing slider under test) is manually placed on the manual trolley 2 of the worktable 3 of the actuator 4, and the manual trolley 2 is pushed to move along the slide rail 5, so that the test piece on the manual trolley 2 is close to the area of ​​the U-shaped frame 7, until it is close to the detection station corresponding to the U-shaped frame 7. When the test piece moves to the designated position with the manual trolley 2, the proximity sensor 10 on the electric push rod 9 detects its presence and sends a trigger signal to the central control unit 1. The operator presses the start button on the central control unit 1, and the equipment enters the automatic testing mode: the central control unit 1 controls the activation of 6 sets of high-precision contact displacement sensors 8 to simultaneously collect the actual measurement values ​​of the test piece and the standard piece in key dimensions. The temperature sensor 6 monitors the ambient temperature in real time (to help ensure the stability of the measurement data). All collected data is transmitted to the central control unit 1 in real time. After the central control unit 1 completes data reading and preliminary processing, it automatically stops the testing program. The operator manually pushes the manual trolley 2 along the slide rail 5 to move it out of the testing station, removes the test piece, and, based on the test results fed back by the central control unit 1, transfers the test piece to the next process (such as warehousing of qualified parts, rework of unqualified parts, etc.). When performing a changeover test on sliders of the same specification but different series, the electric push rod 9 is controlled to adjust the position of the proximity sensor 10, and the detection position of the high-precision contact displacement sensor 8 on the actuator 4 can be finely adjusted. Sliders of the same specification but different series include standard type, extended type, flange type, heightened type, and extended and heightened type.

[0015] In this solution, the quick-connect interface between the central control mechanism 1 and the actuator 4 is achieved through a heavy-duty connector plug. The heavy-duty connector plug features a high-strength, high-reliability plug-in structure, enabling rapid and stable connection and disconnection of electrical signals (such as sensor data signals and control signals) and power signals between the central control mechanism 1 and the actuator 4. When it is necessary to replace actuators 4 of different specifications, simply plugging and unplugging the heavy-duty connector plug is sufficient to connect or disconnect the signals and power signals between the central control mechanism 1 and the actuator 4, eliminating the need for complex wiring or connection operations. This significantly simplifies the replacement process for actuators 4 of different specifications, shortens changeover time, and improves equipment changeover efficiency. Simultaneously, it avoids problems such as poor contact and wiring errors caused by traditional wiring methods, ensuring the stability of signal transmission between the central control mechanism 1 and the actuator 4, indirectly reducing measurement errors caused by signal interference, and improving equipment operational reliability.

[0016] In this solution, the six sets of high-precision contact displacement sensors 8 are used to detect the actual measured values ​​of the test piece and the standard piece in key dimensions such as parallelism, straightness, width, and height, and to assist in calculating the relative difference between the two to determine the accuracy level of the slider. The six sets of high-precision contact displacement sensors 8 correspond to the key detection dimensions of parallelism, straightness, width, and height of the test piece and the standard piece, respectively. Through direct contact between the sensors and the tested parts (test piece and standard piece), the actual dimensional data of both parts in each key dimension are accurately collected. The central control mechanism 1 calculates the relative difference between the test piece and the standard piece in the corresponding dimension based on the collected actual measured values, and determines the accuracy level of the test piece based on this relative difference. By directly collecting data through high-precision sensors, replacing manual readings, human error is reduced, significantly improving the accuracy of measurement data. Simultaneous detection of multiple key parameters such as parallelism, straightness, width, and height is achieved, eliminating the need to measure each parameter individually, greatly improving measurement efficiency. Using the relative difference as the basis for accuracy level determination provides objective and quantitative test results, avoiding the subjectivity of relying on human experience.

[0017] In this design, a marble measuring platform is selected as the workbench 3 to provide a stable bearing reference for the testing process. Marble material has an extremely low coefficient of thermal expansion, high rigidity, and high structural stability, making it resistant to deformation from environmental temperature fluctuations and external impacts. Using the marble measuring platform as the workbench 3 for the actuator 4 provides a flat and stable bearing reference for the actuator 4, standard parts, test pieces, and six sets of high-precision contact displacement sensors 8, ensuring that the relative positions of all components remain stable during measurement and preventing measurement reference shifts caused by workbench 3 deformation. This stable marble bearing reference reduces measurement deviations caused by workbench 3 deformation (e.g., a traditional metal workbench 3), improving the overall measurement accuracy of the equipment.
