Description

A shaft load test fixture Technical Field

[0001] This utility model relates to the field of shaft testing, specifically a shaft load operation test fixture. Background Technology

[0002] The shaft life testing machine can simulate the complex factors that shafts experience in actual working environments, such as various mechanical loads, temperature changes, humidity conditions, and possible vibrations and shocks. By setting specific test parameters, such as rotation speed, load size, and operating cycle, the shaft undergoes long-term, high-intensity continuous testing to observe and record performance changes, thereby verifying whether the shaft's design life meets expected requirements. The performance of a shaft depends not only on its design rationality but also on the materials used. During the testing process, the shaft life testing machine can visually reflect the performance of different materials under specific working conditions, such as wear resistance, fatigue resistance, and corrosion resistance.

[0003] However, current shaft testing methods mostly rely on testing the shaft's repeated rotations to determine its fatigue level after a large number of rotations, rather than effectively testing the shaft's compressive strength. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a rotating shaft load operation test fixture, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a rotating shaft load operation test fixture, including a load tester, a rotating seat mounted on the upper surface of the load tester, a swing bracket mounted inside the rotating seat, an upper mounting bracket mounted above the swing bracket, and a test fixture positioned directly below the swing bracket on the upper surface of the load tester. The test fixture includes: a fixed base plate and a movable pad. A guide groove is formed on the upper surface of the fixed base plate. A positioning bolt is installed inside the movable pad corresponding to the position of the guide groove. A rotating shaft slot is formed on the upper surface of the movable pad. A limit ring is installed above the rotating shaft slot. A positioning screw is installed inside the swing bracket.

[0006] As a further embodiment of this utility model: a clamping groove is provided below the positioning screw, a bearing groove is provided inside the clamping groove, and a rotating bearing is installed at the lower end of the positioning screw inside the bearing groove.

[0007] As a further improvement of this utility model: an adjustment ear plate is installed between the fixed base plate and the load tester, and a drive motor is connected between the side surface of the rotating seat and the swing bracket.

[0008] As a further improvement of this utility model, the positioning screw is rotatably connected to the upper mounting bracket.

[0009] As a further embodiment of this utility model: the movable pad is slidably connected to the guide groove, and the positioning bolt is engaged and rotatably connected to the movable pad.

[0010] As a further improvement of this utility model: the positioning screw is movably connected to the bearing slot through the rotating bearing.

[0011] As a further improvement of this utility model, the limiting ring is fixedly connected to the movable pad.

[0012] As a further improvement of this utility model, a movable shaft is connected between the drive motor and the swing bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting an adjustable movable pad on the fixed base plate, the compressive strength of the rotating shaft can be tested by limiting the rotating shaft inside the rotating shaft slot and cooperating with the positioning screw set above. At the same time, the fixed base plate as a whole can also be tested for the rotation of the instrument after the rotating shaft is assembled under pressure. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] As shown in Figures 1-5, this embodiment provides a rotating shaft load operation test fixture, including a load tester 1. A rotating seat 2 is mounted on the upper surface of the load tester 1. A swing bracket 3 is installed inside the rotating seat 2. An upper mounting bracket 4 is mounted above the swing bracket 3. A test fixture 6 is set directly below the swing bracket 3 on the upper surface of the load tester 1. The test fixture 6 includes: a fixed base plate 601 and a movable pad 602. A guide groove 604 is formed on the upper surface of the fixed base plate 601. Plate 602 is slidably connected to guide groove 604. Positioning bolt 606 is installed inside movable pad 602 at the position corresponding to guide groove 604. Positioning bolt 606 is engaged and rotatably connected to movable pad 602. Rotary shaft groove 603 is opened on the upper surface of movable pad 602. Limiting ring 605 is installed above rotating shaft groove 603. Limiting ring 605 is fixedly connected to movable pad 602. Positioning screw 5 is installed inside swing bracket 3. Positioning screw 5 is engaged and rotatably connected to upper mounting bracket 4.

[0023] As shown in Figures 2-3, in this embodiment, a clamping slot 502 is provided below the positioning screw 5, and a bearing slot 503 is provided inside the clamping slot 502. A rotating bearing 501 is installed on the inner side of the bearing slot 503 at the lower end of the positioning screw 5. The positioning screw 5 is movably connected to the bearing slot 503 through the rotating bearing 501. An adjusting ear plate 607 is installed between the fixed base plate 601 and the load tester 1. A drive motor 7 is connected between the side surface of the rotating seat 2 and the swing bracket 3. A movable shaft is connected between the drive motor 7 and the swing bracket 3.

[0024] The working principle of this utility model is as follows: In use, the rotating shaft with detection is first placed inside the rotating shaft slots 603 on two movable pads 602. The two movable pads 602 are then pressed against the ends of the rotating shaft. The limiting rings 605 above prevent the ends of the rotating shaft from springing up during pressurization. By rotating the positioning screw 5 downwards, the clamping slots 502 are secured above the rotating shaft. Continuous rotational force causes the rotating bearing 501 at the end of the positioning screw 5 to rotate inside the bearing slots 503, pressing the rotating shaft downwards. The deformation of the rotating shaft is then judged. After the detection is complete, the rotating shaft is installed inside the load device to be tested (such as a computer), and the entire load device is placed on the fixed base plate 6. On the upper surface of 01, the movable pad 602 is moved towards the center position inside the guide groove 604 on the upper surface of the fixed base plate 601 by controlling the movable pad 602 to clamp the workpiece and fix it on the upper surface of the fixed base plate 601 by engaging the positioning bolt 606. After rotating the swing bracket 3 and the upper mounting bracket 4 to be perpendicular to the upper surface of the load tester 1, the control positioning screw 5 is engaged and rotated above the upper mounting bracket 4. After the clamping slot 502 is snapped on the top of the computer, the drive motor 7 drives the swing bracket 3 to swing inside the rotating seat 2. This is used to determine the service life of the shaft after multiple tests, and can also be used to determine whether the shaft can still be used after being compressed.
