A turret with a long service life

Abstract

The invention discloses a tool turret with long service life, comprising a main box body, a bearing seat, a main shaft and a cutter head. The bearing seat is connected with the main box body, the cutter head is sleeved outside the bearing seat, and the outer side of the cutter head is provided with A plurality of installation holes for the main shaft to be inserted, wherein, it also includes a sealing mechanism arranged on the installation holes, and a self-lubricating driving mechanism for driving the rotation of the cutter head. The sealing mechanism includes a mounting seat, the mounting seat is provided with a first through hole, and the main shaft has a It extends into the lower end of the first through hole, there is a first gap between the first through hole and the outer side of the lower end, an annular sealing groove is opened on the side wall of the first through hole, and a sealing member is embedded in the annular sealing groove . By adopting the above structure, compared with the prior art, the present invention can improve the sealing performance of the cutter head, and at the same time, self-lubricate the internal parts of the main box, reduce the internal friction force of the cutter turret during operation, and improve the service life of the turret.

Description

technical field [0001] The invention relates to the technical field of turrets, in particular to a turret with a long service life. Background technique [0002] The turret is the core functional component of the CNC machining center. It is mainly used to install tools and realize functions such as turning and milling. The main structure of the turret includes the main box and the cutter head. There are multiple sets of cutters on the cutter head, and the cutter is selected by rotating the cutter head. The working environment of the spindle is relatively harsh, and impurities such as cutting fluid, chips, and dust can easily enter the interior of the cutter head. In the prior art, the joint between the main shaft and the cutter head is sealed by an ordinary rubber ferrule or oil seal. However, when the main shaft rotates at a high speed, the friction of the rubber ferrule may cause wear and tear, thus affecting the sealing effect, and it is easy to cut most of the dirt. Wh...

Problems solved by technology

The working environment of the spindle is relatively harsh, and impurities such as cutting fluid, debris, and dust can easily enter the interior of the cutter head

The existing technology is to seal the joint between the main shaft and the cutter head through ordinary rubber ferrules or oil seals. However, when the main shaft rotates at high speed, the rubber ferrule will rub and cause wear and tear, which will affect the sealing effect, and it is easy to cut most of the dirt. Entering the interior of the cutter head and friction with the spindle, causing wear of the internal parts of the cutter head and reducing the service life of the turret

In addition, most of the cutterheads in the prior art are driven by gears. The gears are easy to wear after long-term work, which further reduces the service life of the turret. In addition, the turret needs to be disassembled frequently to lubricate the internal gears, which is time-consuming and laborious.
