Rotary jacking four-position precision turntable of cast-weld machine

Abstract

The invention discloses a cast-weld machine rotary jacking four-position precision rotary table which comprises a mounting base, a lifting mechanism and an angle adjusting mechanism, a high-precision divider is arranged on the upper end face of the mounting base, a rotary table is arranged at the upper end of the high-precision divider, a plurality of fixed guide shafts are arranged at the upper end of the rotary table, and the angle adjusting mechanism is arranged at the lower end of the rotary table. A linear guide rail is connected to the fixed guide shaft rail in a sliding mode, a rotary disc is arranged on the linear guide rail, brackets are arranged on the four sides of the rotary disc, clamps are arranged on the brackets, the lifting mechanism is arranged on the mounting base and the rotary disc, and the angle adjusting mechanism is arranged on the brackets. The mechanism is simple in structure, reasonable in design, high in indexing precision, high in rigidity, stable in operation, high in efficiency, low in noise, high in repeated positioning precision and long in service life, an existing mechanism can synchronously achieve overturning of the clamp in the rotating process of the rotating disc, the efficiency is higher, and the mechanism is superior to an existing clamp structure.

Description

technical field [0001] The invention relates to the technical field of casting and welding machine equipment, in particular to a four-position precision turntable that is rotated and lifted by a casting and welding machine. Background technique [0002] Casting and welding machine, also known as automatic battery casting and welding machine, is a small valve-controlled sealed lead-acid battery casting and welding equipment. [0003] Disadvantages of the existing technology: [0004] The traditional cast-welded turntable rotates as a clutch-type mechanism. Since the platform uses a motor-driven link mechanism to achieve indexing, the transmission accuracy is low. At the same time, after the rotation is completed, the positioning pin needs to be used to position the turntable, and the positioning accuracy is difficult to guarantee after the positioning pin is worn out. The repeated positioning accuracy is low, which leads to the offset of the relative position of the welding ...

Problems solved by technology

[0004] The traditional casting and welding turntable rotates as a clutch mechanism. Since the platform uses a motor to drive the linkage mechanism to achieve indexing, the transmission accuracy is low. At the same time, after the rotation is completed, positioning pins are needed to position the turntable. After the positioning pins are worn out, the positioning accuracy is difficult to guarantee. The repeat positioning accuracy is low, which leads to the offset of the relative position of the electrode plate and the mold welding, which affects the quality of casting and welding and the stability of the product
