Description

Axle housing mills face drilling frock Technical Field The invention relates to the technical field of axle housing machining, in particular to an axle housing face milling and drilling tool. Background Axle housings are key load bearing members of automotive axles and are used primarily to support and protect final drives, differentials, axle shafts, and the like. At present, in the axle housing mass production process, the tooling is used as a core component for positioning and clamping the axle housing, and the structural rationality of the tooling directly determines the processing quality and the production beat, so that the tooling is one of key factors for restricting the mass production of the axle housing. Most axle housing milling and drilling tools in the prior art are simple in structure, and the loading and clamping operation of the next axle housing to be processed can be performed only after the current axle housing is processed, the clamping is manually released and the finished product is taken down, so that the machine tool is in an idle state for a long time in the loading and unloading stage, the processing efficiency is reduced, and the labor intensity of workers is increased due to manual clamping and clamping releasing. Therefore, aiming at the technical problems, the axle housing milling surface drilling tool is provided. Disclosure of Invention Aiming at the defects in the prior art, the invention provides the axle housing face milling and drilling tool which is convenient for synchronous processing and loading and unloading, can automatically clamp the axle housing to be processed and cancel the clamping of the processed axle housing, and greatly improves the processing efficiency and reduces the labor intensity of workers. An axle housing mills face drilling frock, includes: the base is used for being installed on a processing machine tool; the mounting seat is rotatably arranged at the top end of the base; The first clamping mechanism comprises a mounting plate, a first fixing assembly, supporting seats, clamping blocks and a transmission mechanism, wherein the mounting plate is fixed at two ends of the mounting seat through the first fixing assembly, two groups of supporting seats are oppositely arranged at the top ends of the mounting plate, the clamping blocks are vertically and slidably arranged at the top ends of the four groups of supporting seats, the transmission mechanism is arranged on the two groups of mounting plates and is connected with the base and the four groups of clamping blocks, the rotation of the mounting seat can drive the clamping blocks to be close to or far away from the supporting seats to slide through the transmission mechanism, the sliding directions of the clamping blocks on the mounting plate are opposite, and the rotation directions of the clamping blocks on the mounting plate are opposite The feeding mechanism comprises a sliding plate and a second fixing component, wherein the sliding plate is arranged at the top end of the base in a sliding mode, the second fixing component is arranged on the sliding plate and can clamp or cancel the mounting plate, and the first fixing component is used for fixing the mounting plate while clamping or canceling the mounting plate. The axle housing milling surface drilling tool has the beneficial effects that: Through placing the axle housing to be processed on two sets of supporting seats on one end mounting panel, then drive the mount pad to rotate, the mount pad rotates and drives this mounting panel and other end mounting panel to rotate, and drive two sets of grip blocks on this mounting panel through drive mechanism and be close to the support pad and remove and wait to process the axle housing and carry out the centre gripping fixedly, two sets of grip blocks on the other end mounting panel are kept away from the support pad and are removed fixedly to the axle housing that has processed, when this mounting panel rotates to the slide top, drive the mounting panel of this mounting panel centre gripping of second fixed subassembly, and make first fixed subassembly remove fixedly to this mounting panel, can drive the slide to slide this mounting panel and drive this mounting panel and remove and wait to process the axle housing and remove to the processing position and carry out milling face hole processing, and when processing, can take off the axle housing that has processed from another group mounting panel again, after the processing is accomplished, drive slide reverse slip resets, the centre gripping of second fixed subassembly to the mounting panel is removed, and make first fixed subassembly resume the fixed, the rotation can get into next round processing, be convenient for process and go on with the unloading simultaneously, and can automatic centre gripping wait to process the axle housing and cancel processing and the centre gripping intensity of having improved by a wide margin processing intensi
