Manufacturer direct selling of 12 head trapezoidal lead screw

  The 12 head trapezoidal lead screw is refitted by the lathe, the workpiece rotates, and the cutter head and knurled tool holder move
Remove the tool rest part of the lathe, install the milling head and self-made tool heel on the slide, install the knurled cutter on the tool heel, and place the tool heel in front of the milling cutter head
The left end of the workpiece is clamped with a chuck, the tailstock is removed at the right end, and a support with a longer hollow pipe is installed
In this way, longer raw materials can be clamped at one time (equivalent to more than twice the length of one milling)
The milling part can be cut off and processed, which can reduce the waste of end materials
When specially designed, the polished rod drives the lead screw to rotate in the nut, the left end of the lead screw is equipped with a spring collet, and the workpiece rotates and feeds to the left
Both the polished rod and the lead screw are processed with a hollow tube (reducing the waste of end material)
Because of the long suspension in the middle, it can be supported by auxiliary support
Clamping device of knurling knife
The knurling cutter devices of the two designs are the same, but the connecting part between the support frame and the machine tool is different
A hole is processed on the support frame, and the groove and through hole are milled on the center line of the transverse through hole opposite the processing part: the groove width is the same as that of the knurled tool handle, and the depth is the same as that of the tool handle
Close to the groove joint hole, the lower edge is flush with the groove root, and a narrow groove is milled vertically to facilitate the outflow of fine iron filings extruded by knurling and prevent the knurling wheel from blocking and clamping
The knurling knife is pressed by the quick change cover plate, and the knurling knife handle is pressed tightly by the screw with plum blossom handle
The round steel is knurled after passing through the guide sleeve, followed by high-speed milling to complete two processes at one time
The guide sleeve is quenched and tempered with tool steel, and an opening is milled on it, and its length is flat with the end face of the support
The guide sleeve locating pin hole and assembly screw shall be matched with the support to ensure that the opening is facing the center line of the groove
