Description

Horizontal drilling and tapping integrated machine Technical Field The invention relates to the technical field of automobile accessory machining, in particular to a horizontal drilling and tapping integrated machine. Background In the field of machining, particularly in machining workpieces with multi-surface and multi-angle hole site characteristics such as automobile parts (such as automobile fan bins and automobile display screen back plates), drilling and tapping are two core and frequent processes. The traditional processing mode generally adopts separate procedures and separate equipment for operation, namely, a workpiece is required to be drilled on a drilling machine and then transferred to a tapping machine for tapping. The processing mode of multiple clamping and multiple positioning has the following technical defects: First, machining efficiency is low and accumulated errors are large. The workpiece is circulated and clamped repeatedly among different devices, so that the auxiliary time is increased, the coaxiality and the position accuracy between drilling and tapping are more difficult to ensure, and the product quality is directly influenced. In view of the problem, some drilling and tapping compound machines appear on the market, but most of the drilling and tapping compound machines have limited vertical structures or functional integration levels. Second, multi-angle machining is difficult to achieve. For workpieces such as automobile display screen back plates, which need to be processed with hole systems on different angle planes, a traditional vertical processing center often needs a complex angle head or multiple clamping to finish, and the equipment is high in cost and complex in programming. Third, the cooling and cleaning modes in the processing are extensive. The cooling system in the prior art is mostly normally open type spraying, so that a large amount of cutting fluid is splashed and wasted to pollute the working environment, and meanwhile, scrap iron is easily accumulated on the surface of a workpiece or wound on a cutter and is even blocked into a drill shaft, a tapping shaft or a machine tool gap to influence the processing precision and the service life of equipment. After the processing is finished, the cleaning is usually carried out manually, so that the efficiency is low, and potential safety hazards exist. Fourth, it is difficult to achieve both automation and flexibility. The existing automatic drilling and tapping equipment is either in a special machine form and difficult to adapt to product change, or is an expensive machining center, and has good flexibility but large investment. Disclosure of Invention The invention aims to provide a horizontal drilling and tapping integrated machine, which aims to solve the problems in the background technology. The technical scheme is that the multi-station machining device comprises a workbench, a clamping mechanism arranged on the workbench, a plurality of machining units respectively arranged at the side, the front and the rear of the clamping mechanism, at least one side tapping mechanism and a plurality of obliquely arranged drilling mechanisms, a follow-up cooling system matched with at least part of the machining units and used for cooling a machining area in an adjustable direction in the machining process, and the machining units are arranged around the clamping mechanism to perform multi-directional multi-station cooperative machining on a workpiece clamped on the clamping mechanism, so that the re-clamping of the workpiece is reduced. The plurality of inclined drilling mechanisms comprise an inclined drilling mechanism I, an inclined drilling mechanism II, an inclined drilling mechanism III and an inclined drilling mechanism IV which are arranged on the rear side of the clamping mechanism; The follow-up cooling system comprises a fixed ring, a connector, a supply pipe, a spray head, a baffle shell, a first mounting seat, a third air cylinder and a second mounting seat, wherein the second mounting seat is fixedly connected to one side of the fixed ring, the third air cylinder is rotationally connected to the inner side of the second mounting seat, the first mounting seat is rotationally connected to the other end of the third air cylinder, the baffle shell is fixedly connected to one side, far away from the fixed ring, of the first mounting seat, the spray head is fixedly connected to the inner side of the baffle shell, one end of the spray head is communicated with the supply pipe, and the other end of the supply pipe is communicated with the connector; When the PLC monitors that the load current of the servo motor of the processing machine head (such as the first inclined drilling machine head) is increased (indicating that the cutter is contacted with the workpiece to start cutting), a command is immediately sent. Compressed air or cooling liquid enters through the connector and is conveyed to the spray head throu
