45-degree swing angle head for processing machine tool

Abstract

The invention relates to the technical field of processing machine tool equipment, in particular to a 45-degree swing angle head for a processing machine tool. The 45-degree swing angle head for the processing machine tool comprises a shell, wherein the shell comprises an upper shell and a lower shell; the lower shell is fixedly mounted at the bottom of the upper shell through a bolt; a sealing mechanism capable of reducing the speed of gas, dust and the like which are originally high in speed is arranged between the upper shell and the lower shell; an adsorption assembly capable of preventing scrap iron from entering the shell is arranged in the upper shell; and a gear anti-backlash mechanism capable of eliminating backlash of a gear is arranged in the upper shell. According to the 45-degree swing angle head for the processing machine tool provided by the invention, the gear anti-backlash mechanism is directly connected to a second belt pulley through a motor and then connected onto two first belt pulleys through a synchronous belt, the two first belt pulleys are connected to a small gear at the lower end through a speed reducer, and the small gear is meshed with a large gear, so that the gear anti-backlash effect is achieved; and tensioning wheels are arranged on the two sides of a belt of the belt pulleys, so that the belt can be attached to the belt pulleys more tightly, and the transmission stability of the belt is improved.

Description

technical field [0001] The invention relates to the technical field of processing machine tools, in particular to a 45° swing angle head for processing machine tools. Background technique [0002] The swivel head is a kind of machine tool accessory. After the machine tool is equipped with the swivel head, the tool rotation centerline can be angled to the spindle rotation centerline to process the workpiece. Originally produced in Europe, it has been widely used in various fields of mechanical processing such as aviation, automobiles, and molds. Using the oscillating head can increase the processing range and adaptability without changing the structure of the machine tool, so that some processing that is difficult to complete by traditional methods can be realized, and it can reduce repeated clamping of workpieces and improve processing accuracy and efficiency.

Problems solved by technology

[0003] Today's gear transmission will generate high heat during the meshing movement. In order to prevent the gear from being locked due to thermal expansion during the transmission process, there is a certain gap between the tooth surfaces and a certain space for lubrication. This The gap is very small, but due to the high positioning accuracy and repeat positioning accuracy of the CNC machine tool, the backlash value of the gear in the transmission system will cause a certain gap value during the movement of the CNC machine tool in the opposite direction, which will affect the CNC machine tool. The overall positioning accuracy of the machine tool
