Title:
COMBINED CENTRAL SUPPORT FOR LASER CUTTING PIPE
Document Type and Number:
WIPO Patent Application WO/2020/093259
Kind Code:
A1
Abstract:
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.
