The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: a kind of device that is used for miller part arc surface; Comprise the rotary table, scroll chuck and the positioning sleeve that are arranged on the milling machine table; The scroll chuck that is used for the clamping workpiece is arranged on the revolution table top of rotary table; The positioning sleeve that is used for workpiece is carried out axial location is arranged in the centre bore of scroll chuck, and rotary table connects a drive through worm-and-wheel gear, and drive and motor-driven mechanism are through the driving-belt transmission; On rotary table, be provided with a block with the rotary table motion; Two ends at the block movement locus are respectively equipped with travel switch, and travel switch is fixed on the milling machine table, and are connected with the control circuit of motor-driven mechanism.
Described milling machine table is fixed with a spring steel wire; The upper bend of spring steel wire is also pointed to the workpiece of clamping in the scroll chuck, and the position that spring steel wire points to and the machining starting point of workpiece arc surface are the interval angle that the angle at interval, the center of circle equals two arc surfaces that will process on the workpiece with the rotary table centre of gyration.
Described motor-driven mechanism is provided with the deceleration speed change gear, and the output shaft of motor-driven mechanism is provided with the driving wheel littler than drive, and driving wheel and drive pass through the driving-belt transmission, to obtain the gearratio of a reduction of speed, and the reduction of speed effect of in transmission, having held concurrently.
The beneficial effect of the utility model is: rotate through reducing motor driving rotational workbench, rotating speed is even, improves crudy, reduces labour intensity; The automatic revolution that realizes rotary table through travel switch and block commutates, and has solved the artificial inconvenience of seeing that the scale mark switching-over brings; Through the simple and easy location of a spring steel wire, reached the arc surface on quick index milling 180 degree opposites, improved efficient.

The specific embodiment
Specify the embodiment of the utility model in conjunction with accompanying drawing.
A kind of device that is used for miller part arc surface; Comprise the rotary table 1, scroll chuck 2 and the positioning sleeve 4 that are arranged on the milling machine table; The scroll chuck 2 that is used for clamping workpiece 3 is arranged on the revolution table top 101 of rotary table 1, and the positioning sleeve 4 that is used for workpiece 3 is carried out axial location is arranged in the centre bore of scroll chuck 2.Drive in the process of workpiece 3 rotations at rotary table 1, the slotting cutter 11 on the milling machine table mills out arc surface on workpiece.The utility model adopts a drive to replace the handwheel that is connected with rotary table 1 through worm-and-wheel gear in order to reduce labour intensity.The motor-driven mechanism 5 of one band deceleration speed change gear is installed on milling machine table; Drive 8 passes through driving-belt 12 transmissions with motor-driven mechanism 5, is rotated through driving-belt 12, drive 8 and worm-and-wheel gear driving rotational workbench 1 by motor-driven mechanism 5.The output shaft of described motor-driven mechanism 5 is provided with the driving wheel 7 littler than drive 8, and driving wheel 7 and drive 8 be through driving-belt 12 transmissions, to obtain the gearratio of a reduction of speed, and the reduction of speed effect of in transmission, having held concurrently.In order to realize the automatic control of rotary table 1 rotation; Block 10 with the rotary table motion is set on rotary table 1; At the two ends of block 10 movement locus a travel switch 9 is set respectively; Travel switch 9 is fixed on the milling machine table, and is connected with the control circuit of motor-driven mechanism 5.Starter motor driving mechanism 5 in the course of work behind the correct position of adjustment slotting cutter 11 with respect to workpiece 3, begins to mill arc surface.When block 10 goes to when running into a travel switch with rotary table 1, the arc surface milling stops, rotary table 1 auto-reverse return.When block 10 goes to when running into another travel switch with rotary table 1, rotary table 1 automatic main story begins the milling of next arc surface.
For ease the arc surface position that will process on the workpiece 3 is positioned, do not hinder the loading and unloading of workpiece 3 in scroll chuck 2 simultaneously.Can be at the fixing spring steel wire 6 of milling machine table; The upper bend of spring steel wire 6 is also pointed to the workpiece 3 of clampings in the scroll chuck 2, and the position that spring steel wire 6 points to and the machining starting point of workpiece arc surface are the interval angle that the angle at interval, the center of circle equals two arc surfaces that will process on the workpiece with rotary table 1 centre of gyration.For example, on workpiece 3, process two arc surfaces, and two arc surfaces are provided with at 180 ° of angles at interval, the machining starting point of the position pointed to of spring steel wire 6 and workpiece arc surface is the 180 ° of angles that are separated by, the center of circle with the centre of gyration of rotary table 1 so.When processing work, push spring steel wire 6 aside, workpiece 3 is put into scroll chuck 2, it automatically resets trip spring steel wire 6 backs.After processing first arc surface; Elder generation's withdrawing unclamps the workpiece 3 that is clamped by scroll chuck 2, turning of work piece 3, the position that the initial processing stand alignment springs steel wire 6 of its first arc surface is pointed to; Can play the effect of quick location, clamping work pieces continues second arc surface of processing afterwards.
This device rotates through reducing motor driving rotational workbench, and rotating speed is even; The revolution that realizes rotary table through travel switch and block commutates, and has solved the artificial inconvenience of seeing that the scale mark switching-over brings; Through the simple and easy location of a spring steel wire, reached quick index, the purpose of the arc surface on milling 180 degree opposites.
