Setting groove is then convenient for placing spring, and then optimizes the overall stability of structure, and then by setting counter sink and threaded hole
Convenient for being screwed into bolt, so that convenient limit positioning pin.
The fixed function to spring one end limited block is set then can be played, consequently facilitating the initial setup process of spring, i.e.,
First spring and limited block can be fixed by operator, and positioning pin is then inserted into limit hole, in the process, spring
Situations such as will not falling off, so that installation process is more convenient.
Setting stop collar is then convenient for being engaged with bolt, as long as positioning pin is because of stop collar after positioning pin insertion limit hole
Presence, therefore can be engaged in any direction with bolt, and the structure is relatively stable, fixed effect is preferable.
Setting brake block can then enhance braking effect.
O-ring, which is arranged, then can increase the sealing effect of piston.
The beneficial effects of the utility model are: the utility model provides the brake structure of machine tool chief axis, it can be to machine
Bed main shaft is quickly and effectively braked, and structure is simple, and braking effect is good.
