Round bar center hole machining device

Abstract

The invention relates to the technical field of round bar machining equipment, in particular to a round bar center hole machining device which comprises a workbench, a pressing and limiting assembly, an adjustable drilling assembly, a clamping assembly and an automatic discharging assembly, wherein the pressing and limiting assembly is arranged on one side of the top of the workbench, the adjustable drilling assembly is arranged on the side, away from the pressing and limiting assembly, of the top of the workbench, the clamping assembly is arranged below the pressing and limiting assembly, and the automatic discharging assembly is arranged on the side, close to the clamping assembly, of the top of the workbench. According to the round bar center hole machining device, adjustment can be made in time under the action of the clamping assembly according to different specifications of round bars, so that the round bars are clamped more firmly, the round bars are prevented from shaking and dislocation in the machining process, the machined round bars can be automatically discharged under the action of the automatic discharging assembly, an existing oil cylinder is replaced with a gas-liquid conversion cylinder, cost can be reduced, and the machining precision can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of round bar processing equipment, in particular to a round bar center hole processing device. Background technique [0002] The center hole is a process hole used to process the center of the workpiece. Most shaft parts have a center hole. The main function of the center hole is to serve as a positioning reference for the workpiece during processing and to bear the weight of the workpiece during processing. and cutting force, the existing processing technology for round bars still has the following problems: [0003] The general round rod center hole processing device has poor fixation to the round rod, which causes the round rod to be easily shaken and dislocated, which affects the accuracy and efficiency of the processing hole, and the drilling of the drilling head to the round rod will generate high temperature due to friction, which is not timely Cooling will affect the service life of the drilling hea...

AI Technical Summary

Problems solved by technology

[0003] The general round rod center hole processing device has poor fixation to the round rod, which causes the round rod to be easily shaken and dislocated, which affects the accuracy and efficiency of the processing hole, and the drilling of the drilling head to the round rod will generate high temperature due to friction, which is not timely Cooling will affect the service life of the drilling head and the quality of the processed center hole

[0004] (1) The existing compression device for the center hole of the round rod cannot pre-tighten the round rod, and direct pressure to compress the round rod will cause the center of the round rod to shift, making the machining accuracy insufficient, and the existing The cost of the hold-down device is high, and the high rework rate also leads to loss of efficiency

[0005] (2) The existing fixing device for the center hole of the round bar cannot be adjusted according to the different specifications of the round bar, which causes the round bar to easily shake and dislocate, which affects the accuracy and efficiency of the hole processing

[0006] (3) The existing technology usually requires manual blanking of the processed round bar. Due to the heavy weight of the round bar, manual blanking is extremely time-consuming and laborious
