Problems solved by technology
[0002] Due to the complex shape of the poor material pipe 9, there is an eccentric hole 24 in the shaft hole, and a radial hole 25 is arranged on its tube wall, and the radial hole and the eccentric hole in the shaft hole have relative accurate positions (such as figure 1 , 2 As shown), the eccentric hole is in the shaft hole, and the surface cannot be observed and positioned, so it brings great inconvenience to the machining of the radial hole. It is impossible to accurately position the radial hole relative to the eccentric hole with ordinary processing machinery, so it is difficult for the radial hole to be processed. hole brings difficulty

The invention discloses a lean tube radial hole tool. A central axial hole on a tailstock of a machine tool is provided with a tailstock spindle; the rear end part of the tailstock spindle is provided with a ring slot; the front end surface of the tailstock spindle is provided with a round boss and an eccentric stepped pin hole which are coaxial; a stepped pin is arranged on the eccentric stepped pin hole; a circumferential limit screw slot is arranged on the spindle surface of the tailstock spindle; a screw hole is arranged under a spindle hole on the external end surface of the tailstock; the screw hole is provided with an adjustment rod which is provided with a raised flange disc; the flange disc is matched with the ring slot at the rear end part of the tailstock spindle; a limit screw hole is arranged on the side o the tailstock and is provided with a limit screw; the limit screw is provided with a locking nut; the inner end part of the limit screw is matched with the limit screw slot on the tailstock spindle; a dividing head of the machine tool is provided with a dividing head spindle; a connecting rod is arranged at the outer end of the adjustment rod; the end part of the connecting rod is provided with a crank; and the outer end of the limit screw is provided with a limit hand wheel. By using the tool, the productivity can be improved, the labor intensity of workers can be reduced; in addition, the tool also can ensure that the geometric accuracy and the position accuracy of workpieces meet the requirement of drawing design.
Description
technical field [0001] The invention belongs to mechanical processing technology equipment, in particular to a radial hole tooling for a material-poor pipe. Background technique [0002] Due to the complex shape of the poor material pipe 9, there is an eccentric hole 24 in the shaft hole, and a radial hole 25 is arranged on its tube wall, and the radial hole and the eccentric hole in the shaft hole have relative accurate positions (such as figure 1 , 2 As shown), the eccentric hole is in the shaft hole, and the surface cannot be observed and positioned, so it brings great inconvenience to the machining of the radial hole. It is impossible to accurately position the radial hole relative to the eccentric hole with ordinary processing machinery, so it is difficult for the radial hole to be processed. Holes bring difficulty. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a radial hole tooling for a lean material p...
