Description

Technical Field

[0001] This utility model belongs to the technical field of torsion testing machine, and specifically relates to a calibration device for a torsion testing machine. Background Technology

[0002] A torsion testing machine is a device used to measure the mechanical properties of materials under torsional loads.

[0003] Torsion testing machines are primarily used for testing the torsional strength of metallic or non-metallic materials, and can also be used for torsional strength testing of various parts and components. Their principle is based on applying torque to the material and recording its mechanical properties at different torsional angles, such as yield strength, fracture point, and elastic limit. Torsion testing machines are widely used in various fields, including metals, plastics, and composite materials.

[0004] Currently, existing torsion testing machine calibration devices still have some shortcomings. They are often not very accurate during testing, and the torsion amplitude is easily too large or too small, which affects the calibration effect. Therefore, we propose a torsion testing machine calibration device. Utility Model Content

[0005] The purpose of this invention is to provide a calibration device for a torsion testing machine to solve the problems mentioned in the background art, such as low accuracy during testing, excessive or insufficient torsion amplitude, which affect the calibration effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a calibration device for a torsion testing machine, comprising a worktable and a first clamping plate and a second clamping plate. A gear is provided inside the worktable. A first rotating shaft is fixedly connected to the bottom of the gear, and the bottom of the first rotating shaft is rotatably connected to the bottom of the worktable.

The top of the second rotating shaft is fixedly connected to the bottom of the first clamping plate. A rack is provided on the front of the gear, movably connected inside the worktable, and meshes with the gear. A second clamping plate is provided on the top right side of the worktable, movably connected to the top right side of the worktable. A pressure sensor is fixedly connected to one end of the first and second clamping plates facing each other. A fixed plate is fixedly connected to one end of the pressure sensor. A ball bearing is provided inside the fixed plate, rotatably connected to the inside of the fixed plate.

[0007] Preferably, a support plate is fixedly connected to the right side of the inside of the workbench, and a first electric push rod is fixedly connected to the left side of the support plate. The left side of the first electric push rod is fixedly connected to the right side of the rack.

[0008] Preferably, the workbench has a door on its front side, the door is rotatably connected to the front side of the workbench, and a handle is fixedly connected to the front side of the door.

[0009] Preferably, a support plate is fixedly connected to the top right side of the workbench, and a second electric push rod is fixedly connected to the left side of the support plate. The left side of the second electric push rod is fixedly connected to the right side of the second clamping plate.

[0010] Preferably, a fixed frame is fixedly connected to the bottom of the workbench, and an anti-slip seat is fixedly connected to the bottom of the fixed frame. There are four anti-slip seats, and the bottom of each anti-slip seat is provided with a movable wheel, which is engaged inside the anti-slip seat.

[0011] Preferably, the anti-slip base has two side slots inside, and the movable wheel is fixedly connected to two sides with a locking block. The locking block is adapted to the slot and is engaged inside the slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Move the second clamp to the left to hold the torsion head of the torsion testing machine in conjunction with the first clamp. Push the rack, and the rack will drive the gear to rotate, causing the torsion testing machine to torsion. The ball on the pressure sensor applies pressure to the torsion testing machine. Fix the ball to the force application end to simulate the transmission of point load and realize the detection. The rack drives the gear to rotate to realize the torsion test. The transmission accuracy is high and the power transmission is stable, avoiding the torsion amplitude from being too large or too small, thereby improving the calibration effect.

[0014] 2. The flexible movement of the device is enhanced by the movable wheels. When it needs to be placed on a flat surface, the locking block is removed from the slot, the movable wheels are removed, flipped over, and the movable wheels are locked upwards into the anti-slip seat.
