The link has vertical portion, and there is the contact piece vertical portion rear, and the contact piece is located between last limit switch on the support and the lower limit switch.

The vertical portion of the link has a damper contact portion. The damper contact portion is located above the damper on the bracket.

The cylinder rod of the cylinder extends downward.

The advantages are that:

a novel reaming equipment with full-automatic processing. It can be through attenuator automatic control processing feed volume, reduces the loaded down with trivial details operation of manpower, reduces intensity of labour and improves production efficiency, beats some, and the preliminary steps of drilling etc. are accomplished by other equipment, and this equipment carries out the reaming more accurate to reach more perfect processing effect, guarantee that the smooth finish of reaming reaches the settlement requirement of technology, realize mass production processing.

Detailed Description

A reaming equipment is provided with a base 1, and a support 2 which is vertically arranged is fixed on the base 1.

The top of the bracket 2 is fixed with a belt pulley box 6, and the shell of the motor 15 is fixed with the belt pulley box 6.

The output shaft of the motor 15 is connected with the input shaft of the belt pulley box 6, and the driven belt pulley shaft 24 of the belt pulley box 6 is connected with the vertically arranged main shaft 16.

The upper end of the main shaft 16 is provided with a spline 17 which is inserted into a spline hole of the driven pulley shaft 24.

A sleeve 18 is arranged outside the main shaft 16, and the main shaft 16 is supported in the sleeve 18 through a corresponding bearing.
