Novel counter weight balance system and using method

Abstract

The invention belongs to the technical field of precision machining and testing and provides a novel counter weight balance system and a using method. The novel counter weight balance system is a counter weight system based on a constant load spring device, the work load balance is achieved, meanwhile large self weight of a traditional counter weight is avoided, and the borne pressure and movementdeformation of supporting parts are reduced; the complex problems which exist on aspects of structural design and machining processes of a spring counter weight system are solved; through a double-way locking structure, the rope slipping phenomenon of the tail end of a rope is avoided; and by adopting the mode of adapter-connection plate side surface plastic laminating and end surface plain holedistribution and the method of guiding wheel axial adjustment, the oscillatory motion phenomenon caused by centroid transient shift is reduced, and thus stable movement, in a back surface of an L-shaped adapter plate, of the adapter-connection plate is achieved. The novel counter weight balance system has the advantages that the structure is simple, designing and machining are convenient, the pressure bearing deformation of supporting members is small, and movement is stable, and has good market application prospects and popularization value.

Description

technical field [0001] The invention belongs to the technical field of precision machining and testing, and relates to a novel counterweight balance system and a use method. Background technique [0002] The counterweight balance system is widely used in machine tools, lifting equipment, etc. Its main function is to reduce the load on the motor and reduce the torque required for lifting the work load. [0003] The traditional counterweight balance system includes the main counterweight box and auxiliary counterweight box and the internal counterweight / iron / disk, guide wheels, counterweight support structure, etc. The traditional counterweight balance system adopts the method of adding a counterweight, that is, the weight is connected to one end of the rope, the rope crosses a fixed pulley, and the other end of the rope is connected to a counterweight with the same mass as the weight. When a small torque is applied to the rotating shaft of the pulley, it is possible to lift ...

Problems solved by technology

[0005] In order to overcome the deficiencies of traditional and spring counterweight systems; in order to solve the safety hazards caused by the sliding rope at the end of the rope when the clamp groove structure is used in the counterweight balance system for locking; in order to realize the adapter plate in the L-shaped In order to improve the phenomenon of oscillating motion caused by the transient shift of the center of mass caused by the force on both sides of the vertical direction on the back of the adapter plate, the present invention proposes a counterweight balance system based on a constant load spring device and a method of use. Under the condition of providing constant tension, it achieves a balanced working load while avoiding the large self-weight of the traditional counterweight, reducing the pressure bearing of the supporting member, and reducing the movement deformation of the guide rail; it overcomes the structural design and There are relatively complicated problems in the processing technology; through the two-way locking structure, the safety hazard caused by the sliding rope at the end of the rope is eliminated; the method of using the plastic on the side of the adapter plate and the matching of the installation hole on the end surface and the axial adjustment of the guide wheel improves The phenomenon of oscillation movement caused by the transient deviation of the center of mass is eliminated, and the smooth movement of the adapter plate in the back of the L-shaped adapter plate is realized.
