Damping balance capable of freely adjusting height

Abstract

The invention relates to a damping balance capable of freely adjusting the height, which comprises a base, a guide rail, a fastening slide block structure and a damping balance main body; the guide rail is vertically and fixedly mounted on the base, and the damping balance main body is slidably sleeved on the guide rail through the fastening slide block structure; the damping balance main body is driven to move up and down through the structural combination of the guide rail and the fastening sliding block, the problem that stress on the left side and the right side is different in the lifting process is solved, the balance is stably lifted to the use height, and the distance displayer is arranged on the damping balance main body and can display the horizontal height, the height of the balance platform can be finely adjusted through the shear fork lifting arm, the lifting amplitude is increased, so that the experiment use process is more convenient and practical; the damping structure used for reducing low-frequency vibration can well absorb low-frequency vibration energy, in the weighing process of the balance, the balance can be kept stable, the reading of the balance is more accurate, and the accuracy of experimental results is improved.

Description

technical field [0001] The invention relates to the technical field of balances, in particular to a shock-absorbing balance with freely adjustable height. Background technique [0002] The balance is used to weigh the mass of objects. It has simple structure, low cost, and limited precision. Currently, the balance uses a lifting cylinder to lift the balance and move up and down along the guide device; and the force on the left and right sides is different when lifting, which can easily cause the balance to tilt. , shaking, poor lifting and guiding performance, and the lifting range is too small, which seriously affects the stability and accuracy of the equipment when the balance is used, which will lead to large errors in actual measurement; and the shock absorption of the balance is mainly suitable for small vibration.

[0002] The balance is used to weigh the mass of objects. It has simple structure, low cost, and limited precision. Currently, the balance uses a lifting cylinder to lift the balance and move up and down along the guide device; and the force on the left and right sides is different when lifting, which can easily cause the balance to tilt. , shaking, poor lifting and guiding performance, and the lifting range is too small, which seriously affects the stability and accuracy of the equipment when the balance is used, which will lead to large errors in actual measurement; and the shock absorption of the balance is mainly suitable for small vibration. In the laboratory environment, and for the outdoor environment with large vibration, the shock absorption effect of the existing shock absorption platform is not obvious, the low-frequency vibration caused by sound and manual walking, and the high-frequency vibration caused by the vibration of the cutting equipment, etc. These vibrations will cause the balance to be unstable, which will lead to inaccurate readings, affect the accuracy of the experimental results, and bring certain adverse effects to people's use. In order to increase the lifting range, improve the accuracy and reduce the error, We propose a shock-absorbing balance with freely adjustable height
