Title
(EN) COMBINED CENTRAL SUPPORT FOR LASER CUTTING PIPE
(FR) SUPPORT CENTRAL COMBINÉ POUR DÉCOUPE PAR LASER DE TUYAUX
(ZH) 一种组合式激光切管中心支架
Abstract
(EN)
Disclosed is a combined central support for laser cutting a pipe. The central support comprises a four-claw combined support main body (1) and a large through hole gear transmission assembly (2) which are mutually connected. The four-claw combined support main body comprises four perpendicular single-claw support assemblies (3) arranged in such a manner that every two are opposite one another, wherein each single-claw support assembly is connected with a pulley clamping assembly (4), and the single-claw support assembly is used for driving the corresponding pulley clamping assembly to move. The single-claw support assemblies comprise a power mechanism (5), a tapered wedge mechanism (7) and a displacement transmission mechanism (8), wherein the power mechanism is connected with the tapered wedge mechanism by means of screw rod and nut assemblies (6); the tapered wedge mechanism comprises a tapered wedge connecting block (71), a translation guide rail (72), a translation sliding block (73), a skewing guide rail (74), a skewing sliding block (75) and a skewing adapter plate (76); and the displacement transmission mechanism comprises a perpendicular clamping block (81) and a dovetail moving upper plate (84). The central support is simple in structure, easy to manufacture, good in terms of sealing and dust-proof performances, and low in usage cost.

L'invention concerne un support central combiné pour découper par laser un tuyau. Le support central comprend un corps principal de support combiné à quatre griffes (1) et un ensemble de transmission à engrenage à grand trou traversant (2) qui sont mutuellement reliés. Le corps principal de support combiné à quatre griffes comprend quatre ensembles support à griffe unique perpendiculaires (3) agencés de telle manière que chaque paire est opposée l'une à l'autre, chaque ensemble support à griffe unique étant relié à un ensemble de serrage à poulie (4), et l'ensemble support à griffe unique étant utilisé pour entraîner l'ensemble de serrage à poulie correspondant en déplacement. Les ensembles support à griffe unique comprennent un mécanisme de puissance (5), un mécanisme de coin effilé (7) et un mécanisme de transmission de déplacement (8), le mécanisme de puissance étant relié au mécanisme de coin effilé à l'aide d'ensembles vis, tige et écrou (6) ; le mécanisme de coin effilé comprend un bloc de liaison de coin effilé (71), un rail de guidage en translation (72), un bloc de coulissement en translation (73), un rail de guidage en biais (74), un bloc de coulissement en biais (75) et une plaque d'adaptation en biais (76) ; et le mécanisme de transmission de déplacement comprend un bloc de serrage perpendiculaire (81) et une plaque supérieure mobile en queue d'aronde (84). Le support central est de structure simple, il est facile à fabriquer, il est bon en termes d'étanchéité et de performances anti-poussière, et il a un faible coût d'utilisation.
