Description

Drilling multiaxis device for machining shell Technical Field The invention relates to the technical field of drilling processing, in particular to a drilling multiaxial device for processing a shell. Background In the manufacturing process of various casing components such as a motor casing, a reduction gearbox body, a control cabinet body and the like, drilling is a key and frequent process. In order to improve the machining efficiency and ensure the position accuracy among a plurality of hole sites, a drilling multi-axis machine (also called multi-axis drill or multi-hole drill) is widely applied to production practice. The device is a functional part which can be installed on a vertical drilling machine, a radial drilling machine or a machining center, and has the core effects of driving a plurality of main shafts (i.e. drilling shafts) to synchronously rotate through one power input, so that the one-time multi-hole synchronous machining of workpieces is realized, the production efficiency is greatly improved, and the labor intensity of operators is reduced. The basic construction of prior art drilling multi-axis machines generally comprises an input interface for connection to the machine tool spindle, a housing with a built-in gear or universal coupling drive, and a plurality of output spindles for mounting the drill bits. When the machine tool works, the power of the machine tool is uniformly distributed to all output spindles through the transmission mechanism, and all drill bits are driven to cut simultaneously. However, the conventional drilling multiaxial device has a significant technical disadvantage that the distance between the plurality of output spindles (i.e. the pitch of the hole sites that can be processed) is fixed during design and manufacture, and cannot be adjusted. This means that a conventional multiaxial machine is generally adaptable to only one or a few workpieces having identical hole site layouts. In actual production, once another casing with different hole pitch specifications needs to be processed, the whole multi-axis device needs to be detached from the machine tool and replaced by another multi-axis device with matched hole pitch, or a new multi-axis device is specially customized for a new workpiece. This "one-use" feature results in extremely poor versatility. Along with the trend of market demands on small-batch and multi-variety flexible production modes, the contradiction caused by the defects is more remarkable, and enterprises either store a large number of multi-axis machines with different specifications to adapt to different products, so that the equipment purchase and management cost is high, the occupied space is large, or custom production is frequently carried out, so that the production preparation period is long and the response speed is low. This severely limits the flexibility of the production line and the overall cost effectiveness. Therefore, developing a universal drilling multi-axis device with adjustable spindle spacing and capable of rapidly adapting to different workpiece hole spacing requirements becomes a technical problem to be solved in the field. Disclosure of Invention The invention aims to provide a drilling multi-axis device for machining a shell, so as to solve the problems in the prior art. The drilling multiaxier for machining the shell comprises four device main bodies which are fixedly arranged at the corners of the periphery of a square support through mounting plates, a placing table is connected to the surrounding middle parts of the four device main bodies through square positioning seats, the placing table is used for positioning and mounting workpieces through positioning rods, and cutting fluid conveying devices are arranged around the square positioning seats; The device main part is including the hydraulic telescoping rod towards placing a middle part to and install in the connecting pipe on hydraulic telescoping rod flexible top constitutes, and the connecting pipe loops through bolt mounting inner shell body and shell body, still drives two connectors of vertical symmetry installation in shell body department through the main shaft connecting piece in the connecting pipe, is fixed with a drilling head in two connectors respectively. As a further improvement of the scheme, the main shaft connecting piece is formed by cooperation of the driving unit and the adjusting unit, the main shaft connecting piece comprises a main shaft which is rotationally connected with the inner shell through a bearing, one end of the main shaft is connected with a main shaft transmission motor, the other end of the main shaft is positioned in the outer shell and is connected with a multi-stage gear, the multi-stage gear comprises a first main gear, a second main gear, a third main gear and a fourth main gear which are coaxially and uniformly connected to the outer shell, and the diameters of the first main gear, the second main gear, the third m
