Description

Technical Field

[0001] This utility model relates to the technical field of parts strength testing devices, specifically a device for testing the compressive strength of shaft parts. Background Technology

[0002] As is well known, shaft parts need to undergo various parameter tests before leaving the factory, such as shaft diameter, shaft length, chamfers, and shaft strength, which requires strength testing equipment. During installation, shaft parts are typically installed horizontally or vertically. Regardless of the installation method, the axial compressive strength of the shaft parts must be qualified. Otherwise, after installing load-bearing drive wheels, the shaft parts may twist and deform, rendering the equipment inoperable. Therefore, testing equipment is needed to test the compressive strength of the shafts.

[0003] Existing technology publication CN219694747U discloses a device for testing the compressive strength of shaft parts, belonging to the field of strength testing technology. It includes a frame, within which a vertically arranged electric actuator is installed, with a pressure sensor mounted on the top surface of the actuator; a vertically arranged screw is located at the top of the frame, with a pressure block at its bottom, the pressure block and the pressure sensor arranged vertically opposite each other; the shaft part is placed on the pressure sensor; rotating the screw causes the pressure block to press against the top of the shaft part, positioning it or moving it away from the shaft part; the electric actuator pushes the pressure sensor upwards; the relative force between the pressure block and the electric actuator compresses the shaft part, causing deformation; the pressure sensor detects the compressive strength of the shaft part. This application is simple to operate, provides accurate measurements, eliminates the need for repeated measurements, improves work efficiency, and easily meets work requirements.

[0004] However, existing shaft parts compressive strength testing devices typically require applying pressure to the shaft parts during use to test their compressive strength. However, during the pressure application process, some shaft parts may break apart due to quality issues, or spring open due to improper installation or excessive pressure. Since the shaft parts compressive strength testing device is difficult to protect against, it is easy to accidentally injure workers, resulting in poor safety of the shaft parts compressive strength testing device. To address this issue, we propose a shaft parts compressive strength testing device. Utility Model Content

[0015] (III) Beneficial Effects

[0016] This utility model provides a device for testing the compressive strength of shaft parts, which has the following advantages:

[0017] (1) This type of shaft part compressive strength testing device, through the setting of protective frame, protective net, protective frame and shielding net, during the testing process, the lifting motor drives the lifting screw to rotate clockwise, and the nut seat will drive the protective frame to move downward through the adjustment groove due to the rotation direction of the lifting screw.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4This utility model provides a technical solution: a device for testing the compressive strength of shaft parts, including a testing frame 3, a testing base 1 fixedly connected to the bottom of the testing frame 3, a lifting motor 16 installed inside the testing base 1, a lifting screw 17 fixedly connected to the drive end of the lifting motor 16, a protective frame 9 fixedly connected to the top edge of the testing base 1, a protective net 10 fixedly connected to the top of the protective frame 9, an adjustment groove 11 opened on one side of the testing frame 3, a protective frame 12 movably connected to one side of the testing frame 3 through the adjustment groove 11, a shielding net 13 fixedly connected inside the protective frame 12, a top seat 7 fixedly connected to one side of the top of the testing frame 3, a testing rod 8 installed on the top of the top seat 7, and a control panel 4 fixedly connected to the front of the testing frame 3.

[0025] Furthermore, a displacement sensor 801 is fixedly connected to the bottom end of the detection rod 8, and a pressure block 802 is fixedly connected to the bottom end of the displacement sensor 801. The pressure block 802 presses against the shaft part and applies pressure, while the displacement sensor 801 detects the displacement of the shaft part.

[0026] Furthermore, the outer side of the lifting screw 17 is threaded with a nut seat 18, which is movably connected to the protective frame 12. The lifting motor 16 drives the lifting screw 17 to rotate clockwise, and the nut seat 18 will cause the protective frame 12 to move downward through the adjustment groove 11 due to the rotation direction of the lifting screw 17.

[0027] Furthermore, a pressure sensor 14 is embedded in the top of the detection base 1, and a detection platform 15 is installed on the top of the pressure sensor 14. The pressure sensor 14 can be used to apply pressure to the pressure block 802 against the shaft part for detection.

[0028] Furthermore, four casters 2 are fixedly connected to the bottom of the testing base 1. The four casters 2 are located at the four corners of the bottom of the testing base 1, which facilitates the movement of the testing device by the staff.

[0029] Furthermore, a display screen 6 is embedded in the front of the control panel 4, and operation buttons 5 are fixedly connected to the lower part of the front of the control panel 4 away from the display screen 6. The display screen 6 makes it easy for staff to view the test data, and the operation buttons 5 make it easy for staff to operate and use the test device.

[0030] Furthermore, the detection base 1 is made of metal material, and the outer surface of the detection base 1 is smooth. The detection base 1 made of metal material is more sturdy and durable and is not easily damaged.

[0031] Working Principle: After installation, the installation, fixation, and safety protection of this utility model are checked first. When using the shaft part compressive strength testing device, the operator places the shaft part on the testing platform 15, then starts the testing rod 8. The testing rod 8 drives the pressure block 802 to move downward. At this time, the pressure block 802 presses against the shaft part and applies pressure. The pressure sensor 14 monitors the applied pressure, and the displacement sensor 801 detects the displacement of the shaft part. Simultaneously, during the testing process, the lifting motor 16 drives the lifting screw 17 to rotate clockwise, and the nut seat 18 rotates clockwise due to the lifting screw 17. The rotation of 7 will cause the protective frame 12 to move downward through the adjustment groove 11. At this time, the shielding net 13 on the protective frame 12 will shield the front of the detection device. When the shaft part breaks or pops open, the protective net 10 on the protective frame 9 can protect the back and right side of the detection device, so that the shaft part will not move out of the detection area even if it breaks or pops open. After the detection is installed, the detection rod 8 will drive the pressure block 802 to reset. At this time, the shaft part can be taken out. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
