Description

Technical Field

[0001] This utility model relates to the field of scraping tooling, and in particular to a scraping tooling for fixing the spindle box of a drilling and tapping machine. Background Technology

[0002] As the requirements for machined parts in industries such as precision instruments and aerospace continue to increase, current technology generally involves placing the spindle box on the ground for scraping, making it impossible to level the measurement with a dial indicator. Traditional methods cannot constrain translational motion in the X and Y directions, thus failing to address the issue of ease of operation for scraping personnel.

[0003] Currently, many of these methods involve scraping on soft rubber mats placed on the ground, but the friction of the rubber mats alone cannot constrain translational motion in the X and Y directions.

[0004] Therefore, it is necessary to propose a scraping fixture for fixing the spindle box of a drilling and tapping machine to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This scraping fixture for fixing the spindle box of a drilling machine allows the spindle box to be placed on top of it via a scraping component. The hard rubber sheet installed in the inner cavity of the mounting slot is used for scraping. The fixture body prevents leveling with a dial indicator, effectively improving the scraping accuracy of the spindle box.

Based on this, the distance between the two scraping components can be adjusted according to the size of the spindle box. It can be adapted to spindle boxes of various sizes when performing scraping work.

[0014] 3. This scraping fixture for fixing the spindle box of a drilling and tapping machine can effectively limit the spindle box during scraping by setting a limiting component. The limiting component has a certain telescopic effect through the setting of the second movable groove, the fixing rod and the spring, which can further improve the adaptability of the spindle box. The setting of the pulley can reduce the friction between the spindle box and the spindle box wall during scraping. Attached Figure Description
