Abstract

Provided is a building hoist stand column port cutting fixture and a machining method of a stand column port. The cutting fixture is arranged on a guide track of a body of a lathe. The cutting fixture is provided with a fixture seat (10) which is matched with the guide track of the lathe, a shaft sleeve (5) which is fixedly connected with the fixture seat (10), a first bearing (4), a second bearing (6), hollow rotating shafts (7) which are arranged inside the first bearing (4) and the second bearing (6), flange plates (2) which are fixedly connected with one ends of the hollow rotating shafts (7), and self-centering chucks (1) which are connected with the flange plates (2) and are coaxial with a chuck of the lathe. The first bearing (4) and the second bearing (6) are arranged at two end portions of the shaft sleeve (5). The machining method includes the following steps: mounting the cutting fixture on the guide track of the body of the lathe; enabling a stand column to penetrate through the hollow rotating shafts of the cutting fixture, clamping and fixing one end of the stand column through the chuck of the lathe, clamping and fixing the portion close to a cutting tool through the self-centering chucks; and cutting the stand column port.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a cutting fixture used in the cutting process of a construction lift column port; the invention also relates to a cutting process method for a construction lift column port. Background technique [0002] The construction elevator is also called the construction elevator for construction. It is a manned and cargo-carrying construction machine often used in construction. Because of its unique box structure, it is comfortable and safe to ride. The construction elevator is usually used with the tower crane on the construction site. The frame of the construction hoist is composed of several standard sections. With the development of the construction industry, the maximum erection height of the construction hoist has reached 150 meters, and the height of the construction hoist can be increased to 250 meters by using a heavier standard section. Therefore, the processing accuracy of the standard secti...
