Problems solved by technology

This scheme is simple in structure and stable in operation, but it brings two problems: first, it takes a certain amount of time for the piston rod in the cylinder to extend; second, non-linear factors such as leakage and compression of the working medium (liquid or gas) in the cylinder , the influence of these two factors makes it difficult for the positioning device to ensure that the turntable is accurately positioned at the predetermined position
Therefore, for the occasions that require precise positioning in industrial production, this solution has obvious limitations

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0022] Such as Figure 1 to Figure 5 As shown, a dual hydraulic motor synchronous positioning turntable assembly according to the present invention includes a positioning table 4, a hydraulic motor assembly 1 and a toothed outer ring turntable bearing 2, and the positioning table 4 includes a positioning table base 402, and the positioning table base 402 A number of connecting threaded holes 401 are opened on the top. The toothed outer ring slewing bearing 2 includes an outer gear ring 201 and an inner gear ring 202. The hydraulic motor assembly 1 meshes with the toothed outer ring slewing bearing 2 through gears. . A plurality of connection holes 203 are opened on the inner ring gear 202, the outer ring gear 201 and the hydraulic motor assembly 1 are geared together, an...

Abstract

The invention relates to a double-hydraulic-motor synchronous positioning rotary table assembly. The assembly comprises a positioning table and a hydraulic motor assembly, the positioning table is fixedly provided with a toothed outer ring rotating disc bearing and a ball plug positioning assembly, a positioning annular groove is formed in the lower side face of the toothed outer ring rotating disc bearing, the ball plug positioning assembly is located below the positioning annular groove of the toothed outer ring rotating disc bearing, and the hydraulic motor assembly is meshed with the toothed outer ring rotating disc bearing through a gear. The ball plug positioning assembly comprises a plunger base, a plunger is arranged on the plunger base, a spring and a ball base are installed in the plunger, a positioning ball is fixed to the ball base, the positioning ball is connected with the positioning annular groove through a rolling pair, and a plurality of concave spherical surfaces areformed in the positioning annular groove. The double-hydraulic-motor synchronous positioning rotary table assembly can be used for solving the problem of inaccurate positioning caused by non-linear factors such as oil liquid compression and gear backlash during positioning of a station rotary table, and the positioning precision is high.

Description

technical field [0001] The invention relates to a dual hydraulic motor synchronous positioning turntable assembly. Background technique [0002] Due to the large driving torque required for large-tonnage automatic station turntables, hydraulic motors are often used as the driving force source. A complete rotary process usually includes multiple steps, which means that the turntable needs to be stopped for positioning. [0003] The traditional station turntable positioning is realized only by motor shutdown, but due to the backlash between the two meshing gears, it cannot be used for the accuracy requirements of high-precision turntable positioning. [0004] The Chinese patent with the application number CN106826721A proposes a movable positioning turntable assembly. The invention is provided with a clamp arm driven by a cylinder and an annular side wall coaxial with the turntable at the bottom of the worktable. When the turntable needs to be synchronized, the piston in the ...
