A chip-clearing jig and chip-clearing method

Abstract

The invention discloses a chip-clearing clamp and a chip-clearing method automatically. The core clamp includes: a pull rod (1), a clamp connecting plate (2), a positioning mandrel (7) and a tensioning mandrel (5). The positioning mandrel (7) is connected to the clamp connecting plate (2), the tie rod (1) is connected to the center guide hole of the clamp connecting plate (2), the connecting port of the pulling rod (1) is connected to the connecting end of the tensioning mandrel (5), and the positioning The mandrel (7) is connected with a positioning sleeve (3) and an expansion sleeve (4), which is characterized in that: the tie rod (1) and the tension mandrel (5) are provided with air passages and communicated, and the air outlet of the tie rod (1) It is connected with the air inlet of the tensioning mandrel (5), the air inlet of the tie rod (1) is connected with the blower device, and the air outlet of the tensioning mandrel (5) is located at the position between the tensioning mandrel and the top of the tailstock (6) of the machine tool. position. After the fixture is assembled in the present invention, the pores communicate with each other. It is used for some iron filings on the outer surface of fixtures such as blowing sleeves, and realizes the automatic removal of the center hole of the expanding core fixture and the iron filings pasted on the top.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a method for removing the center hole of a cutting and grinding fixture and the iron filings pasted on the tip, and a core expanding fixture for automatic chip removal. Background technique [0002] When lathes and grinders are equipped with expanding core fixtures and use the top to process shaft workpieces, the iron chips generated sometimes stick to the center hole of the fixture and the top. The general method of cleaning is to manually blow air with an air gun or water gun and pour in cutting fluid to ensure that the fixture is not damaged. The center hole and the tip are clean. Before the shaft is positioned and clamped, the iron filings and other dirt in the center hole of the fixture and the tip must be removed to realize the correct positioning of the shaft workpiece, otherwise it will affect the coaxiality of the inner hole and the outer circle of the shaft w...

Problems solved by technology

However, using air guns and water guns to increase the manual operation steps is time-consuming and laborious, and the center hole and top of the fixture are generally in the direction of the tailstock of the machine tool, which is not easy to operate, and sometimes it is not clean
