Problems solved by technology
The traditional method of operation is that the efficiency is too low, and the second is that despite repeated corrections, the two center holes still have errors with the ideal rotary surface. Therefore, using the current lathe to drill the center hole is time-consuming and laborious, and the accuracy is not high.

A lathe with an automatic drilling device inside the main shaft, the first oil cylinder piston is connected inside the hollow rotary hydraulic cylinder, the inner end of the first oil cylinder piston is connected with a hollow tie rod, the main shaft is externally connected with a driven pulley, and the hollow rotary hydraulic cylinder A hydraulic feed cylinder is installed on the outside of the rear housing of the main shaft, and a piston rod is connected to the inside of the piston of the second oil cylinder, and the hollow pull rod passes through the piston rod of the piston of the second oil cylinder; a hollow hydraulic chuck is connected to the outside of the inner port of the main shaft, and the hollow A lever pressure plate is hinged inside the hydraulic chuck, and a wedge block is connected to the inner port of the hollow pull rod. The inclined surface of the wedge block is in transmission contact with one end of the lever pressure plate, and the other end of the lever pressure plate is transmission-connected with three chuck jaws; the second oil cylinder The inner end of the piston rod of the piston is connected with a center drill feed pull rod. The front end of the center drill feed pull rod is provided with a center drill.
Description
technical field [0001] The invention relates to a lathe, in particular to a lathe with an automatic drilling device in the main shaft. Background technique [0002] When machining shaft parts on small and medium-sized lathes, it is necessary to drill center holes at both ends. The traditional method is to first clamp the outer circle of one end, drill the center hole on the outer circle of the other end, and then turn around and block the outer circle end of the machine. 1. Drill the center hole on the other side of the outer circle at the other end of the car. [0003] Since the center hole of the shaft workpiece acts as a benchmark for the machining and positioning of the shaft workpiece, the processing quality of the center hole directly affects the quality of the product. For high-precision shafts, secondary drilling and expansion of the center hole is required, and even further grinding of the center is required. hole. The traditional operation method is firstly ineff...
