Problems solved by technology

In deep hole machining, due to the limitation of the tool diameter and the requirement of the cantilever length of the deep hole tool, the rigidity of the tool is weak, and it is difficult to process with high material removal efficiency. In order to meet the processing requirements, in the traditional deep hole processing technology More processes are used in the process, resulting in lower removal efficiency

Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] refer to Figure 1 to Figure 8 , a tool for high-efficiency machining of deep holes in the oil pump housing of the present invention, including a cutter bar 7 and a blade 8 fixedly mounted on the cutter bar 7, the blade 8 has cutting edges on both sides, and the cutting edge is provided with micro Cutting edge 83. A plurality of blades 8 are installed on the cutter bar 7, and the blades 8 are evenly and fixedly connected to the cutter bar 7 by bolts and gaskets. The blades 8 are arranged at intervals along the axial direction of the cutter bar 7, and the number of blades 8 installed on the cutter bar 7 is n, according to the depth h of the hole in the cutting process 4 And the length L of blade 8 decides, n is an integer. In this way the blade 8 can cover the entire depth of the hole. The distance h between adjacent blades 8 is 0.5-1um, w...

Abstract

The invention discloses a high-efficiency deep hole machining tool in an oil pump housing, which comprises a tool bar and a blade fixedly installed on the tool bar. Both sides of the blade have cutting edges, and the cutting edges are provided with micro-cutting edges. A deep hole high-efficiency machining system with the machining tool includes a vibrating horn and a piezoelectric actuator, and the vibrating horn transmits vibration to the tool. The present invention improves the processing stability of the cutting process and the surface quality of the workpiece through the micro-cutting edges on both sides of the blade, and reduces the burrs on the inner surface of the deep hole and the fillet; It is transmitted to the blade, so that a stable ultrasonic vibration cutting cycle is generated during the cutting process, and the surface quality of the workpiece is further improved.

Description

technical field [0001] The invention relates to the field of deep hole machining tools, in particular to a high-efficiency deep hole machining system in an oil pump housing. Background technique [0002] The internal structure of the oil pump housing is complex. Since the lubricating coolant circulates in the internal pipeline, the surface morphology and residual height of the internal deep holes have become an important factor restricting the improvement of energy efficiency. In deep hole machining, due to the limitation of the tool diameter and the requirement of the cantilever length of the deep hole tool, the rigidity of the tool is weak, and it is difficult to process with high material removal efficiency. In order to meet the processing requirements, in the traditional deep hole processing technology More processes are used in the process, resulting in lower removal efficiency. Contents of the invention [0003] The present invention aims to solve the above-mentione...
