Embodiment Construction

[0021] Such as figure 1 As shown, a drum device includes a drum 1 installed on the frame, an indexing drive mechanism, a positioning mechanism and a drum clamping mechanism, the drum 1 is installed on the frame through the drum shaft, and the drum 1 It has multiple stations, and each station has a workholding fixture. The indexing drive mechanism and the positioning mechanism are located on the same side of the drum 1, and the drum clamping mechanism is located on the other side of the drum 1. The frame includes left and right wall panels on both sides of the drum, and a fixed beam at the top of the left and right wall panels connecting the left and right wall panels.

[0022] The indexing drive mechanism drives the drum 1 to rotate to each station according to the indexing requirements. The indexing drive mechanism includes a servo motor 3-1, a reducer 3-2, a synchronous belt 3-3 and a synchronous pulley 3-4, and the synchronous pulley 3-4 is installed on the drum shaft and...

Abstract

The invention relates to a drum wheel device, which comprises a drum wheel, an indexing driving mechanism, a positioning mechanism and a drum wheel clamping mechanism, which are mounted on a rack; the indexing driving mechanism drives the drum wheel to rotate to all stations according to indexing demands; the positioning mechanism comprises a positioning oil cylinder, and a positioning hole in the side surface of the drum wheel; the positioning oil cylinder comprises a cylinder body, a piston rod and a piston arranged in the cylinder body; the piston rod in the cylinder is divided into a thick part and a thin part; a step for pushing the piston rod to move to one side of the drum wheel under the action of hydraulic oil is formed at the jointing position between the thick part and the thin part; the piston is slidably sleeved at the thick part of the piston rod; a limiting part for preventing the piston from sliding to the thin part is arranged at the thick part of the piston rod; the drum wheel clamping mechanism pushes the drum wheel shaft to axially move and enable the drum wheel to tightly lean onto the rack, so the drum wheel is clamped. The drum wheel device has the beneficial effects that the drum wheel device is simple in structure, convenient to manufacture, large in indexing speed, small in impact, high in indexing precision, small in abrasion and good in precision retainability.

Description

technical field [0001] The invention relates to a drum arrangement. Background technique [0002] The indexing drive mechanism of the traditional drum device usually adopts the forms of plane Markov mechanism, spherical Markov mechanism, rack and pinion mechanism with swing oil cylinder, rack and pinion mechanism with ratchet pawl, etc. The common characteristics of these forms are The mechanism is complex, the manufacturing precision of parts is high, the wear is large, and the precision retention is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a drum device with high indexing speed, small impact, high indexing accuracy and good accuracy retention. [0004] The technical solution adopted by the present invention to solve its technical problems is: a drum device, including a drum mounted on the frame, an indexing drive mechanism, a positioning mechanism and a drum clamping mechanism, and the drum is ins...
