Combined type laser pipe cutting center support

Abstract

The invention discloses a combined type laser pipe cutting center support, and relates to the field of laser cutting. The combined type laser pipe cutting center support comprises a four-claw combinedsupport main body and a large through hole gear transmission assembly which are connected to each other; the four-claw combined support main body comprises four vertical single-claw support assemblies, every two of the four single-claw support assemblies are oppositely arranged, each single-claw support assembly is connected to a pulley clamping assembly, and the single-claw support assemblies are used for driving the corresponding pulley clamping assemblies to move; each single-claw support assembly comprises a power mechanism, an inclined wedge mechanism and a displacement transmission mechanism; the power mechanisms are connected to the inclined wedge mechanisms through screw rod nut assemblies; each inclined wedge mechanism comprises an inclined wedge connecting block, a translation guide rail, a translation sliding block, an oblique moving guide rail, an oblique moving sliding block and an oblique moving adapter plate; and each displacement transmission mechanism comprises a vertical clamping block and a dovetail moving upper plate. The center support has the advantages of being simple in structure, easy to manufacture, good in sealing and dust preventing effects and low in use cost.

Description

technical field [0001] The invention relates to the field of laser cutting, in particular to a combined laser tube cutting central support, which is mainly used for clamping rotating tubes for laser cutting. Background technique [0002] The current pipe cutting center support mainly includes a mounting base plate, a servo motor, a clamping device, a controller and a large through-hole bearing, wherein the servo motor and the large through-hole bearing are fixed on the mounting base plate. The ring is connected with the servo motor, and the servo motor drives the toothed outer ring of the large through-hole bearing to rotate through gear transmission, thereby driving the printed circuit board, clamping device, controller and the clamped pipe on the toothed outer ring of the large through-hole bearing to synchronize rotate. [0003] The clamping device has 2 sets of 4 clamping support plates in total, each clamping support plate slides on the corresponding linear guide rail ...

AI Technical Summary

Problems solved by technology

[0005] 1. The clamping force of the clamping device clamping the pipe fittings comes from the linear stepping motor. Due to the current technical level and the limitation of the volume of the center bracket, the clamping force of the clamping pipe fittings generated by the linear stepping motor is too small to meet the clamping requirements. Requirements for heavier fittings

[0006] 2. Due to occasional equipment failure or human reasons, pipe fittings rotate or sag at one end, which will generate a large reverse force on the clamping device. These large reverse forces are finally transmitted to the linear stepper through the screw rod. Motor, which often leads to damage to the linear stepper motor, complex maintenance and high cost

[0007] 3. Due to the limitation of the structure and volume of the center support, the sealing degree of the moving parts such as the linear guide rail slider and the screw nut in the clamping device is relatively low, and a large amount of dust, water, and oil stains generated during laser cutting are easy to penetrate into these moving parts And it is difficult to clean, which seriously reduces the service life of the center support
