the utility model discloses a deep hole reaming device for stabilizing a cutter bar, which comprises a cutter bar, a cutter body vertically fixed with the side wall of the front end of the cutter bar, a support bearing arranged in front of the fixed position of the cutter body on the side wall of the cutter bar, and a disc-shaped support body arranged behind the fixed position of the cutter body on the side wall of the cutter bar; the outer diameter of the supporting bearing is matched with the initial inner hole diameter of the part to be reamed, and the outer diameter of the supporting body is matched with the inner hole diameter of the part to be reamed after reaming.
During reaming, firstly, inserting the front end of the deep hole reaming device into an initial inner hole of a part to be reamed, and supporting the outer ring of the support bearing on the inner wall of the initial inner hole of the part to be reamed; the deep hole reaming device comprises a cutter body, a support body and a support body, wherein the cutter body is used for cutting and reaming the inner wall of a part to be reamed, when a cutter bar of the deep hole reaming device advances to the support body and enters the inner cavity of the part to be reamed, the outer ring of the support body is supported on the inner wall of the inner cavity of the part to be reamed, the reaming part is completed, in the forward feeding process of the deep hole reaming device, the outer ring of a support bearing is always supported on the inner wall of the initial inner hole of the part to be reamed, the outer ring of the support body is always supported on the inner wall of the inner cavity of the part to be reamed, the cutter bar cannot vibrate in the feeding process, and the machining.
The supporting bearing adopts a deep groove ball bearing.
The front end of the cutter bar is in threaded connection with a compression nut, and the rear end face of the compression nut compresses the inner ring of the support bearing.
The excircle of the supporting body is radially inwards provided with an insertion groove with the width matched with the diameter of the cutter bar, and the supporting body is inserted into the side wall of the cutter bar through the insertion groove.
The supporting bodies are axially and uniformly distributed behind the cutter bar side wall cutter body fixing position.
The cutter body compresses tightly the side wall of the cutter bar through a set screw.
Advantageous effects
The utility model discloses a deep hole reaming device, simple structure, the cost of manufacture is low, through set up support bearing and set up the supporter in the cutter arbor rear end at the cutter arbor front end, at the deep hole reaming device in-process of advancing, support bearing's outer lane is supported all the time on the inner wall of treating the initial hole of reaming part, and the inner chamber inner wall of reaming part has been accomplished in the outer lane of supporter supports all the time, the cutter arbor can not take place the phenomenon of quivering at the feed process, has guaranteed the machining precision of reaming operation.
