Material Guide Device And Automatic Lathe
First Claim
1. A material guide device, comprising:
- a guide bush having a material introducing end and a material lead-out end, as axially opposite ends, and including a hollow-tubular material support section elastically displaceable in a radial direction about a guiding axis; and
an adjusting mechanism for adjusting a radial dimension of said material support section of said guide bush;
said adjusting mechanism comprising;
a carrying member carrying said guide bush, and having a front face disposed around said material lead-out end of said guide bush;
a pressing member disposed near said front face of said carrying member and movable relative to said carrying member and able to make a relative linear motion along said guiding axis relative to said guide bush, the pressing member causing an elastic displacement in said radial direction on said material support section by said relative linear motion; and
a feed screw structure causing said relative linear motion between said pressing member and said guide bush by a mutual screwing motion of threads.

Abstract
A material guide device (10) comprises a guide bush (22) having a material support part (20) elastically displaceable in a radial direction, and an adjusting mechanism (24) adjusting the radial dimension of the material support part of the guide bush. The adjusting mechanism further comprises a carrying member (40) having a front face (40b) disposed around the material lead-out end (22b) of the guide bush and carrying the guide bush, a pressing member (42) disposed near the front face of the carrying member movably relative to the carrying member and linearly movably relative to the guide bush along a guiding axis and causing the radial elastic displacement on the material support part by the relative linear motion, and a feed screw structure (44) causing the relative linear motion between the pressing member and the guide bush by the screwing motion of a screw.

18. A material guide device, comprising:
-
a guide bush having a material introducing end and a material lead-out end, as axially opposite ends, and including a hollow-tubular material support section elastically displaceable in a radial direction about a guiding axis; and
an adjusting mechanism for adjusting a radial dimension of said material support section of said guide bush;
said adjusting mechanism comprises;
a carrying member having a front face disposed around said material lead-out end of said guide bush, and carrying said guide bush in a state as to be secured in a rotational direction about said guiding axis;
a pressing member disposed, near said front face of said carrying member, to be able to make a relative linear motion along said guiding axis relative to said guide bush, the pressing member causing an elastic displacement in said radial direction on said material support section by said relative linear motion; and
a feed screw structure disposed near said front face of said carrying member at a position remote from said material introducing end of said guide bush, for causing said relative linear motion between said pressing member and said guide bush by a mutual screwing motion of threads. - View Dependent Claims (19)
