Manufacturing method for sleeve pipe mounted on middle planker

Abstract

A manufacturing method for a sleeve pipe mounted on a middle planker comprises the following steps: 1, cylinder processing: blanking, large end cutting and small end cutting, small end excircle gear grinding allowance and inner hole cutting, and taper hole gear grinding, bolt hole drilling, heat treatment and fine inner hole grinding; 2, seat processing: casting, scribing, bottom surface peeling, inner hole cutting and fine boring, and threaded hole drilling and tapping; 3, drilling and tapping on the large slide carriage of a lathe by using a motor drill, and fixing a positioning plate; 4, fixing a support in a proper position of the middle planker of the lathe; 5, mounting a set screw at the slotted long cylindrical post end on the support by using a nut for locking, and propping the cylindrical end of the bolt on the positioning plate; 6, fixing the seat onto the middle planker of the lathe so as to enable the axial line of the inner hole of the seat to be basically coaxial with the rotation axis of the main shaft of the lathe; 7, clamping a boring bar onto the main shaft of the lathe, the feeding a cutter into the middle planker and finely boring the inner hole of the seat; 8, grinding the excircle of the small end of the cylinder according to the dimension of the finely bored seat so as to enable the match of the cylinder and the inner hole of the seat to be H7/h6; 9, fixing the cylinder into the inner hole; and 10, fixing a hand wheel onto a lead screw and mounting the lead screw into the screw hole of the cylinder. The manufacturing method is simple, scientific and low in cost, and has high economic benefits.

Description

Technical field [0001] The invention relates to a method for manufacturing accessories of metal processing machine tools, in particular to a sleeve mounted on a middle carriage. Background technique [0002] Workers in the machinery industry know that drilling, reaming or reaming of parts on a lathe requires a drill, a reaming knife and a reamer, and these tools are installed in the taper hole of the tailstock sleeve of the lathe. The process needs to be replaced. In actual operation, every time a tool is used, the tailstock must be moved back and forth manually, and the hand wheel is rotated manually, which is time-consuming and labor-intensive. The main accuracy of the sleeve installed on the middle carriage is that the axis of the inner hole where the tool is installed is basically coaxial with the axis of the lathe spindle. To achieve this, use ordinary methods: it is very difficult to process all parts into assembly. Difficult to do. Summary of the invention [0003] The p...

Problems solved by technology

In actual operation, every time a tool is used, the tailstock must be manually moved back and forth, and the handwheel must be manually turned, which is time-consuming and labor-intensive.

The main precision of the sleeve mounted on the middle pallet is that the axis of the inner hole where the tool is installed is basically coaxial with the rotation axis of the lathe spindle. To achieve this purpose, use an ordinary method: it is very difficult to process all the parts into assemblies. Difficult to do
