Movable balance weight and manufacturing process thereof

Abstract

The invention discloses a movable balance weight and a manufacturing process thereof. The movable balance weight comprises a mounting frame, threaded rods are connected to the inner walls of the two sides of the mounting frame through bearings, a mounting table is arranged on the outer wall of one side of the mounting frame, a motor is arranged on the outer wall of one side of the mounting table, and one end of an output shaft of the motor is connected to one ends of the threaded rods. First sliding grooves are formed in the two sides of the outer wall of the bottom of the mounting frame, sliding blocks are slidably connected to the inner walls of the two first sliding grooves, the same main balance weight is arranged at the top ends of the two sliding blocks and arranged on the outer walls of the threaded rods, adaptive inserting grooves are formed in the two sides of the outer wall of the top of the balance weight, and transverse frames are arranged on the outer walls of the two sides of the mounting frame. According to the movable balance weight, a balance weight plate on the main balance weight can be gradually transferred, an effective balance fine adjustment effect is achieved, the balance weight produced through the method is low in cost, shrinkage gaps do not occur, the problem of spalling under atrocious weather does not need to be worried about, and a cast shell is not prone to deformation.

Description

technical field [0001] The invention relates to the technical field of balance weights, in particular to a movable balance weight and a manufacturing process thereof. Background technique [0002] Counterweight is an important accessory used in forklifts, excavators, loaders and other construction machinery vehicles to ensure operational stability. At present, there are mainly the following two methods of counterweight manufacturing on the market: the first is a solid balance weight that is formed at one time by casting process, and its material is generally cast iron; the second is the process of casting or steel plate stamping welding counterweight shell , the process is to first cast a shell made of cast iron or steel stamping and welding, and then pour the filling material. [0003] At present, the balance weight manufactured by the first solid cast iron process has high manufacturing costs, a large amount of steel resources and energy consumption, and cannot meet the n...

AI Technical Summary

Problems solved by technology

[0003] At present, the balance weight manufactured by the first solid cast iron process has high manufacturing costs, a large amount of steel resources and energy consumption, and cannot meet the national requirements for energy saving and carbon reduction; while the balance weight of the cast iron shell produced by the second method has the following problems Defects: 1) There is no tight connection between the shell and the canned material, leaving a shrinkage gap;

[0004] 2) It is difficult to completely discharge the water, causing corrosion of the shell, and it is easy to swell and crack in extreme weather; 3) Since filling materials need to be poured into the shell, there are canning holes reserved on the surface of the shell, which affects the structure and structure of the entire balance weight. Appearance; 4) Due to the large volume of the shell, it is easy to deform during casting, which affects product quality; and the supporting balance weight can only be adjusted as a whole during use, and it is difficult to flexibly adjust with the goods in the cargo compartment of the transport vehicle
