Special equipment for drilling and reaming large scale equipment dowel hole

Abstract

The invention relates to special equipment for drilling and reaming a large scale equipment dowel hole. The special equipment is composed of a portal frame, a main shaft box, a drilling device, lead screws, rotating wheels, guide rails and a control device. Supports on two sides are connected with a top beam, a transverse beam is arranged in the middle, a rotating wheel is arranged on the lower side of each support, two guide rails are arranged on the lower sides of the rotating wheels, and therefore the portal frame capable of moving forwards and backwards and braking is formed. The lead screws are arranged in the two supports and the transverse beam, the supports and the transverse beam are connected through guide rail armature iron pressing plates, the transverse beam can move vertically on the portal frame formed by the supports, the main shaft box is installed on the transverse beam, the drilling device is installed in the main shaft box, the main shaft box and the drilling device can move horizontally on a guide rail of the transverse beam, and tightening blocks are installed in the main shaft box and the drilling device. Processing of the dowel hole of large scale equipment is convenient, locating is accurate, stable, high in power and high in efficiency in the process of machining, holes which cannot be machined via a drilling machine can be machined by the special equipment, and machining range of hole drilling and reaming is enlarged.

Description

technical field [0001] The invention relates to a special equipment for drilling and reaming positioning pin holes of large-scale equipment Background technique [0002] In the field of mechanical processing and equipment installation, after a piece of equipment is finally installed and tested for running performance, all parts of the equipment must be positioned and fixed. The positioning methods are nothing more than bolts, welding, direct pins and taper pins. This process is very important. If there is no positioning, the parts of the equipment after handling, lifting, installation and operation are easy to loosen and misplace, which will change the performance of the equipment or even damage it. The processing of the positioning taper pin hole and the installation of the taper pin are an important task. Usually, when the taper pin is drilled and reamed in the factory, after the production equipment has been installed and the trial run is completed, the drilling and reami...

Problems solved by technology

This process is very important. If there is no positioning, the parts of the equipment will be easily loosened and misplaced after handling, lifting, installation and operation, which will change the performance of the equipment or even damage it.

The processing of the positioning taper pin hole and the installation of the taper pin are an important task. Usually, when the taper pin is drilled and reamed in the factory, after the production equipment has been installed and the trial run is completed, the drilling and reaming is performed with a hand electric drill or manually. Due to manual operation No positioning center, swinging back and forth, lack of axial force, drill bit, reamer in the drilling and reaming process gradually increases as the drilling goes deeper into the reaming hole, and the cutting resistance gradually increases, the reamer often swings or breaks , which makes drilling and reaming difficult. The more important difficulty is that most of the drilling and reaming taper holes are used for the positioning of various parts of the equipment, and the equipment is often carried out after the installation is completed. Because the equipment to be processed is relatively large, if you want to put the equipment It is impossible to transport the drilling machine to the drilling machine. It is difficult to transport the drilling machine to the front of the equipment, but because the rocker arm and the base of the drilling machine are close to each other, it is difficult to implement. Therefore, after drilling with a hand electric drill, reaming with a hand electric drill or manual reaming is difficult. Difficult to twist, time-consuming and labor-intensive, which brings a lot of trouble to the work
