Technical field
The utility model relates to a kind of secondary process instrument of milling machine, relates in particular to a kind of Milling Process clamping that is used for the processing of annular thin wall shell.
Background technology
The shell of workpiece is a kind of annular thin wall part, normally adopts one to press the mode on a top to process on Milling Machining Center.Workpiece shell work in-process, if the Milling Process clamping is excessive to Milling Force in the clamping weak effect of workpiece shell or the process, the workpiece shell will be moved or high vibration so.The mobile back of workpiece shell just must be proofreaied and correct, and this greatly reduces production efficiency; And the radial cutting force that the vibration of workpiece shell produced also can influence the service life of machining tools such as its milling clamping and milling cutter, and the workpiece case surface that processes also chatter mark can occur.These all not only influence machining accuracy, also influence the quality of processing work finished product.
The clamping structure that present technician adopts in the Milling Process of annular thin wall shell is: comprise the scroll chuck that is fixed on the milling center, and positioning disk.Scroll chuck is provided with three-jaw chuck, and the positioning disk endoporus is outwards tightened (seeing accompanying drawing 2) by three-jaw chuck, thereby positioning disk is fixed on the scroll chuck.Workpiece shell one side leans against on the positioning disk, with the seam positioning and clamping of positioning disk; The shell opposite side leans against on the ring flange, fixes (seeing accompanying drawing 1) by the ring flange seam.But all having in various degree in reality processing, vibration produces and the positioning disk displacement, when using this clamping method, positioning disk is not subjected to displacement, it is just quite high just the three-jaw chuck on the scroll chuck to be collapsed the requirement of tight positioning disk, even can not guarantee that like this work in-process is not in the phenomenon that produces vibration and displacement, in case produce above-mentioned reason, workpiece quality and cutter life will be had a greatly reduced quality.
The utility model content
The purpose of this utility model is to provide a kind of Milling Process clamping that is used for the processing of annular thin wall shell, and it is simple in structure, and is easy to operate, accurate positioning, can improve the crudy and the working (machining) efficiency of workpiece, prolong the service life of cutter, alleviate labor strength.
The purpose of this utility model is achieved through the following technical solutions: a kind of Milling Process clamping that is used for the processing of annular thin wall shell, comprise chuck, positioning disk, ring flange that sets gradually along horizontal axis and the holding device that is connected with ring flange, described chuck is fixed in the milling in the heart; Described positioning disk is provided with the scrobicular ring that matches and be connected with chuck, and described positioning disk is fixed on the described chuck by hold-down bolt.
Described positioning disk is provided with the boss seam of stationary annular thin-wall shell; Described ring flange one side is provided with the seam of stationary annular thin-wall shell, and opposite side ring flange center is provided with the taper hole that is connected with the holding device coupling.
Described chuck is provided with draw-in groove, and described positioning disk is provided with via hole, and described hold-down bolt passes the positioning disk via hole and draw-in groove is fastenedly connected.
Scrobicular ring diameter on the described positioning disk card is 160mm, and the center of circle of described via hole is 70mm to the distance in the positioning disk center of circle.
The quantity of described via hole is 3.
The utility model compared with prior art has following advantage and beneficial effect: after the utility model removes three claws of original technology, adopt the mode that compresses that positioning disk is fixed again, can adopt former program to cut.In the actual milling, chatter mark does not appear in sound, workpiece processing rear surface that vibration do not occur yet, has improved the machining accuracy and the end product quality of workpiece shell.

The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but embodiment of the present utility model is not limited thereto.
As illustrated in fig. 1 and 2, a kind of Milling Process clamping that is used for the processing of annular thin wall shell for prior art comprises scroll chuck 1, positioning disk 2, ring flange 3 and holding device 4.Scroll chuck 1 is provided with three claws 11.Positioning disk is provided with positioning disk mesopore 21 on a side that is connected with scroll chuck.Described positioning disk is provided with the boss seam 22 of stationary annular thin-wall shell; Described ring flange one side is provided with the seam 31 of stationary annular thin-wall shell, and the opposite side center is provided with the taper hole 32 with the holding device coupling; Described holding device comprises holder and is located at the top-fastening rod 41 that mates with ring flange center taper hole 32 on the holder.
