Abstract
Description
Technical Field
[0001] The utility model relates to a testing bracket with wheels. Background Art
[0002] In a system using transmission parts, such as a belt-driven system, a pulley is required to transmit the belt. The pulley can change the extension direction of the transmission part, tension the transmission part, change the wrap angle of the transmission part, transfer energy from the transmission part to the component, etc. Therefore, the pulley plays a very important role in the transmission system.
[0003] In order to test the performance of the pulley, the pulley needs to be fixed to a specific test machine. However, when testing different pulleys, it is necessary to complete the test on the same machine as much as possible to reduce the test cost, speed up the test, and shorten the test preparation time.
[0004] Therefore, a wheeled test stand is needed. Utility Model Content
[0005] The technical problem to be solved by the present invention is to provide a pulley test bracket which can be adapted to pulleys of different diameters.
[0006] In order to solve the above technical problems, the present invention provides a pulley test bracket, which is used to adapt to pulleys of different diameters and can clamp the pulleys, including a main body, which is provided with at least two symmetrically arranged long arms, and the long arms are provided with claws that can move and be fixed along the long arms, and also include a clamping member that cooperates with the claws and fixes the claws on the long arms.
[0007] The beneficial effect of the invention is that the clamping claws whose positions can be adjusted relative to the main body can be used to adapt to pulleys of different diameters, which shortens the adaptation time, improves production efficiency, and saves testing costs. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 This is a three-dimensional schematic diagram of the pulley test stand and pulley for this creation.
[0009] Figure 2 This is a three-dimensional schematic diagram from another angle of the claw of the pulley test bracket for this creation. DETAILED DESCRIPTION
[0010] The following is combined with Figure 1-2 Provide a clear and complete description of this creative wheeled test stand.
[0011] A pulley test stand is used to adapt to pulleys of different diameters and can clamp the pulley 5. The pulley test stand includes a body 1, which is provided with at least two symmetrically arranged long arms 2. Preferably, the long arms 2 can be three or four symmetrically arranged, such as three long arms 2 divided into three equal parts, or four long arms 2 divided into four equal parts. The long arms 2 are provided with claws 3 that can move and be fixed along the long arms 2, and clamping members 4 that cooperate with the claws 3 and fix the claws 3 on the long arms 2. Each claw 3 is provided with an arc-shaped clamping surface 31 that cooperates with the circular outer surface of the pulley 5 on the radial inner side. The long arm 2 is provided with a hollow narrow hole 21, and a bolt serving as a clamping member 4 is provided on the other axial side of the long arm 2 relative to the claw 3. The bolt passes through the narrow hole 21 of the long arm 2 and is screwed with the threaded hole 33 of the claw 3. When the claw 3 can move along the long arm 2, the bolt and the claw 3 are relatively loosened, and when the claw 3 clamps the pulley 5, the bolt and the claw 3 are tightened.
[0012] In a preferred embodiment, the claw 3 is clamped on the long arm 2 from both sides of the long arm 2 and can move along the long arm 2. In other optional embodiments, the claw can be in other shapes, such as an L-shape hung on the long arm and can move along the long arm. The long arm does not need to be provided with a narrow hole, and the structure is simpler. Alternatively, the long arm can also be provided with a T-shaped slot, and the claw is provided with a corresponding T-shaped shape, and can slide along the long arm in the T-shaped slot. It can be seen that the cooperation forms of the long arm and the claw are various, and they are not described one by one here. All forms that can achieve the purpose of this creation can be applied to this creation.
[0013] For pulleys 5 of different heights, for example, the central axis of the pulley 5 and the edge of the pulley have different axial heights, corresponding designs need to be made for some pulleys with higher central axes. The radial inner side of each clamping claw 3 is provided with clamping surfaces of different radii arranged radially, and the clamping surfaces of different radii have different axial heights, and the radius of the clamping surface 32 axially away from the long arm is larger than the radius of the clamping surface 31 axially close to the long arm.
[0014] The other side of the body 1 relative to the clamping pulley 5 is provided with a mounting platform 11 for cooperating with a testing device.
[0015] The above technical solution is only an explanation of the implementation example of the present invention, and is not a limitation of the present invention. Any equivalent changes made by those skilled in the art based on the present invention shall fall within the protection scope of the present invention.
