Embodiment

[0026] like Figure 1-3 As shown, a general-purpose long screw shaft diameter processing support device includes a support assembly 1 sleeved outside the long screw 2 to be processed, the support assembly 1 is supported by the center frame of the lathe, and the support assembly 1 is fixed on the Fixing mechanism on long screw 2. The fixing mechanism includes non-standard screws 9 and V-shaped blocks 10 (the fixing mechanism in this embodiment is the same as that in the Chinese invention patent CN2019103250336, so it will not be repeated here). The support assembly 1 includes a sleeve 3 and a support ring 14 , the support ring 14 is located in the middle of the outer wall of the sleeve 3 , and several slide grooves 12 are arranged on the sleeve 3 along the axial direction of the long screw 2 . The chute 12 is symmetrically distributed on both sides of the support ring 14 , wherein the spacing between adjacent chute 12 on the same side of the support ring 14 is equal, and the f...

Abstract

A universal long screw shaft diameter machining supporting device comprises a supporting assembly and a fixing mechanism. A sliding groove is formed in the supporting assembly, and the two ends of the fixing mechanism are fixed to the sliding groove and a long screw to be machined respectively. A flange is arranged at the outer end of the supporting ring, and a stiffening plate is further arranged between the flange and a sleeve. The supporting assembly comprises an upper arc section and a lower arc section. According to the supporting device, the fixing mechanism slides to a proper position in the axial direction in the assembling process, and therefore interference between the fixing mechanism and a spiral structure on the screw can be avoided. The combined structure of the flange and the stiffening plate can greatly increase the contact area between the supporting device and a lathe center frame roller, and vibration generated between the supporting assembly and a lathe center frame is avoided. The supporting device is divided into two detachable parts, frequent shaft penetrating operation during assembly and disassembly of the integral supporting device can be avoided, assembly and disassembly are fast, operation is easy, welding is not needed, universality and durability are good, long screws of various specifications can be machined through one supporting device, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to mechanical processing, in particular to a universal long screw shaft diameter processing support device. Background technique [0002] In machining, the machining of the long axis generally requires the use of additional tooling to support it to enhance its rigidity. Patent CN2019103250336 discloses an easy-to-assemble and disassemble long screw shaft diameter processing support device. By setting a fixing mechanism on the support component to fix the support component on the long screw, the support component and the fixing mechanism can be reused. However, in production practice, it is found that there are many problems with this support device: when the support device is used, it needs to be installed frequently on the production site with driving and manual cooperation, the process is complicated, the operation is difficult, and the efficiency is low; the fixed screw assembly can only To adapt to the long screw of specific ...
