Description

Technical Field

[0001] This utility model relates to the technical field of gearbox testing equipment, specifically a gearbox running-in sample device for rapid positioning and clamping. Background Technology

[0002] In the field of gearbox manufacturing, newly assembled gearboxes need to undergo a break-in test to verify the fitting accuracy of internal parts (such as drive shafts, bearings, worm gears, etc.) and whether the machining dimensions of the parts meet the requirements of actual working conditions. Existing equipment mainly relies on manual observation or post-testing to monitor the break-in process, lacking the function of real-time acquisition and analysis of key parameters such as temperature and torque. It is impossible to detect assembly deviations or abnormal wear problems in a timely manner, resulting in insufficient accuracy and reliability of test data.

[0003] Chinese Patent CN102620936B discloses a bearing break-in testing device. It includes an operating cabinet, a break-in test bench, and a core sleeve assembly / disassembly table, which are connected in series via hydraulic oil pipes. The break-in test bench consists of a housing, spindle, pulley, gearbox, clamping cylinder, V-seat, stop pin, set nut, loosening nut, clamping device, core sleeve, and electromagnetic speed-regulating motor. The core sleeve assembly / disassembly table consists of a hydraulic cylinder, pressure head, support, and bed. This device drives the rolling bearing to be broken in at a certain speed, simultaneously applying a certain radial load to the bearing for a certain break-in period to remove fine burrs and shallow marks, eliminating adverse effects and thus preventing potential accidents. However, this device relies on hydraulic cylinders for clamping and manual or semi-manual adjustment using mechanical components such as stop pins and nuts. The clamping process involves multiple steps, resulting in low positioning efficiency and failing to meet the need for rapid positioning. Therefore, it is imperative for those skilled in the art to solve these technical problems. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned prior art, improve the positioning efficiency of gearboxes to be broken in, and improve the reliability of the test results of internal components of gearboxes.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A gearbox break-in sample device for rapid positioning and clamping includes a frame, a rapid positioning and clamping device, a drive assembly, and a control assembly;

[0007] The rapid positioning and clamping device, drive assembly, and control assembly are all fixedly mounted on the frame.

[0008] The rapid positioning and clamping device includes a positioning base and a clamping mechanism. The positioning base is fixedly installed on the top of the frame, and a positioning groove is provided on the top surface of the positioning base. The clamping mechanism includes an upper pressing component and a side top component. The upper pressing component is fixedly installed above the positioning base by a mounting bracket, and the side top component is fixedly installed on the side of the positioning base by a mounting seat.

[0009] The drive assembly includes a motor and a frequency converter. The motor is fixedly mounted on one side of the frame, and its output shaft is coaxially connected to the input shaft of the gearbox via a coupling. The frequency converter is fixedly mounted in the electrical control cabinet of the frame and is electrically connected to the motor via wires.

[0010] The control component includes a temperature sensor, a torque sensor, a data acquisition module, and a data processing unit. The temperature sensor and the torque sensor are fixed to the motor via threaded connections or clamps. The data acquisition module is fixedly mounted on the frame. The signal input terminal of the data acquisition module is electrically connected to the temperature sensor and the torque sensor via wires, and the signal output terminal of the data acquisition module is electrically connected to the data processing unit via wires. The data processing unit is fixedly mounted inside the electrical control cabinet of the frame.

[0011] By adopting the above technical solution, the frame, as the core load-bearing structure, integrates and fixes the rapid positioning and clamping device, drive components, and control components, forming a compact, integrated device. The various functional modules achieve spatial coordination through the physical connection of the frame, avoiding the operational inconvenience caused by a scattered layout and ensuring precise linkage between components, thus providing a structural foundation for the efficient conduct of gearbox break-in tests.

[0012] Furthermore, the upper pressure assembly includes a lower pressure fixing cylinder, the cylinder body of which is fixedly connected to the frame via the mounting bracket, and the piston rod of which extends vertically downward to above the positioning groove;

[0013] The side-top assembly includes a cylinder propulsion device and a propulsion fixture. The cylinder body of the cylinder propulsion device is fixedly connected to the frame via a mounting base. The propulsion fixture is fixedly connected to the piston rod of the cylinder propulsion device and extends horizontally toward the positioning groove.

[0014] By adopting the above technical solution, the lower pressing and fixing cylinder of the upper pressing component is fixed above the positioning base by the mounting bracket, and the cylinder propulsion device of the side top component is fixed to the side of the positioning base by the mounting seat. This vertical and horizontal bidirectional assembly allows the gearbox sample to be initially aligned by the positioning groove during clamping, and to be fixed without gap by the rapid advancement of the cylinder piston rod. This significantly shortens the clamping time. At the same time, the multi-directional clamping force distribution improves the stability of the sample and avoids test errors caused by displacement during the break-in process.

[0015] Furthermore, both the pressing and fixing cylinder and the cylinder propulsion device are equipped with air pressure regulating valves at their air source interfaces, and the air pressure regulating valves are connected to an external air source through pipelines.

[0016] By adopting the above technical solution, the pneumatic pressure regulating valve is directly installed at the air source interface of the pressing and fixing cylinder and the cylinder propulsion device, and connected to an external air source through pipelines, thus integrating the clamping force adjustment function with the cylinder body. Operators can control the cylinder's output pressure in real time by adjusting the pneumatic pressure regulating valve, which not only adapts to the clamping requirements of gearboxes of different sizes or materials, but also avoids the cumbersome steps of disassembly and adjustment required by traditional mechanical clamps, further improving the flexibility and efficiency of the clamping process.

[0017] Furthermore, the control circuit of the frequency converter extends to the operation panel of the electrical control cabinet, and the operation panel is provided with a speed parameter input interface.

[0018] By adopting the above technical solution, the inverter's control circuitry is extended to the electrical control cabinet's operating panel, and the assembly relationship of the speed parameter input interface is set on the panel, realizing direct connection of the drive components. Operators do not need to enter the electrical control cabinet for debugging; they can adjust the inverter parameters in real time through panel input, thereby controlling the motor speed. This significantly improves the switching efficiency between different operating conditions (such as low-speed break-in and high-speed testing), meeting diverse testing needs.

[0019] Furthermore, the signal output terminal of the data processing unit is electrically connected to the display screen of the rack, and the display screen is fixedly installed on the front panel of the rack.

[0020] By adopting the above technical solution, the data processing unit, through an assembly method where its signal output terminal is electrically connected to the display screen on the front panel of the frame, links the acquisition, processing, and visualization functions of monitoring data, such as temperature and torque. Real-time monitoring data, after being processed by the data acquisition module and data processing unit, is directly presented on the display screen. Operators can intuitively observe parameter changes during the break-in process without additional equipment, facilitating timely detection of anomalies, such as sudden temperature increases or torque fluctuations, and enabling intervention measures. This effectively improves the reliability of test data and the accuracy of assessing the condition of internal gearbox components.

[0021] Furthermore, the positioning groove is adapted to the gearbox to be run-in, and the inner surface of the positioning groove of the positioning base is provided with anti-slip texture, which contacts and engages with the bottom surface of the gearbox to be run-in.

[0022] By adopting the above technical solution, the design of the positioning groove adapting to the gearbox to be broken in, combined with the contact fit between the anti-slip texture on the inner surface of the positioning groove and the bottom surface of the gearbox, allows the contour of the positioning groove to quickly guide the gearbox sample into the correct position when it is placed, reducing manual alignment time. The anti-slip texture increases the contact friction, preventing the sample from sliding or shifting due to external force before clamping, further shortening the clamping preparation time. At the same time, it provides a stable initial positioning basis for the subsequent pressure and precise clamping of the side top components.

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model forms a clamping structure with vertical and horizontal bidirectional coordination by fixing the positioning base of the quick positioning clamping device to the top of the frame, fixing the upper pressure component to the upper part of the positioning base through the mounting bracket, and fixing the side top component to the side of the positioning base through the mounting seat. This allows the gearbox sample to be run-in to be pre-aligned by the positioning groove and fixed without gap by the rapid advancement of the upper pressure and side top components during clamping, which significantly improves the clamping efficiency and the stability of the sample during the run-in process.

[0025] 2. This utility model extends the control line of the frequency converter to the operation panel of the electrical control cabinet and sets up a speed parameter input interface on the panel. This realizes direct connection between the operation end and the control end of the drive component. The operator can adjust the motor speed in real time by inputting through the panel without entering the control cabinet. This simplifies the switching process between different working conditions, such as low-speed break-in and high-speed testing, and improves the convenience of test operation.

[0026] 3. This utility model achieves this by sequentially and electrically connecting the temperature sensor, torque sensor, data acquisition module, and data processing unit, and connecting the output of the data processing unit to the display screen on the front panel of the frame. This enables key parameters such as temperature and torque during the break-in process to be collected, processed, and visualized in real time. Operators can intuitively observe data changes and promptly detect abnormalities, effectively improving the reliability of monitoring the test results of internal components of the gearbox.

[0027] 4. This utility model achieves an integrated design of clamping force adjustment function and cylinder body by directly installing the air pressure regulating valve at the air source interface of the pressing and fixing cylinder and the cylinder propulsion device, and connecting it to the external air source through pipeline. The operator can directly adjust the air pressure regulating valve to control the cylinder output pressure, flexibly adapting to the clamping requirements of gearboxes of different sizes or materials, avoiding the cumbersome steps of disassembly and adjustment required by traditional mechanical clamps, and further improving the flexibility of the clamping process.

[0038] In one embodiment, refer to Figure 5As can be seen, the gearbox to be run-in is first placed in the positioning groove 211 on the top surface of the positioning base 21. The positioning groove is adapted to the gearbox, and the anti-slip texture on the inner surface increases the contact friction to prevent slippage.
