Background
Machining refers to a process that utilizes mechanical equipment to change the physical dimensions or properties of a workpiece. In the process of continuing to process, a large number of machining devices, lathes, grinding machines or milling machines, etc. need to be introduced. Lathe work is a part of machining that performs turning work on a rotating workpiece mainly by a turning tool. Various turning surfaces such as inner and outer cylindrical surfaces, inner and outer conical surfaces, threads, grooves, end surfaces, forming surfaces, etc. can be machined using different turning tools or other tools in a lathe apparatus. The machining precision can reach IT8-IT7, and the roughness Ra value of the machined workpiece surface is usually 1.6-0.8. Turning is often used to machine single axis parts such as straight shafts and general disks, sleeves, etc.
At present, common machining process steps are that turning is firstly carried out on a workpiece; then, the workpiece is polished. In the process, different distinction can be made on grinding precision according to actual processing requirements. However, the turning and polishing processes are performed separately, which takes a lot of time for practical production, and is not beneficial to the whole mechanical process. In addition, in both machining steps, a large amount of cooling liquid is consumed, so that the resource waste is caused, and the resource recovery is not facilitated.
Based on this, chinese patent CN113927311B discloses a turning and polishing integrated machine for numerical control machining, which comprises: bear the base, the top fixedly connected with headstock that bears the base, the front of headstock rotates installs three-jaw chuck, just the front fixedly connected with of headstock two slip backup pads, two the top slidable mounting of slip backup pad has the cutting subassembly of polishing, the front fixed mounting that bears the base has the piece collecting box, the cutting subassembly of polishing includes the connector, one side slidable mounting on connector top has the knife rest, the opposite side slidable mounting on connector top has the base of polishing. This kind of turning all-in-one of polishing uses through the cooperation of first worm wheel and first worm and the cooperation of second worm wheel and second worm, by the removal of connector again, drives the runner of polishing and rotates consequently to the low-speed normal running fit high-speed pivoted work piece of runner of polishing polishes the cutting surface of work piece, has improved polishing efficiency.
However, the turning and polishing integrated machine for numerical control machining disclosed above has a technical problem that it is not suitable for machining large-sized parts with large diameters and short lengths. Specifically, the turning and polishing integrated machine for numerical control machining disclosed above can also be used for machining parts with multiple axes, such as parts of a crankshaft, an eccentric wheel or a cam disc and the like, by changing the installation position of a workpiece or modifying a lathe appropriately. In particular, in single-piece small-batch production, various shaft, disc, sleeve and other parts are processed by a horizontal lathe or a numerical control lathe with wide adaptability. In the prior market, the large-sized parts with large diameter and short length generally refer to large-sized parts with the length-diameter ratio of 0.3 to 0.8, and the large-sized parts cannot be applied to horizontal machine tools for machining. That is, the turning and polishing integrated machine disclosed in the prior art can only be suitable for processing single workpieces in small batches; but not for large diameter and short length workpieces; because the horizontal machine tool cannot effectively fix and turn the workpiece.
