Guide rail 39 rotates counterclockwise, so that product and product fixed part be driven to rotate together.Product fixed part rotates to setting
It is limited after angle by rotation angle limited block 15, rotation is then navigated to by the locating rod 26 connected on positioning power source 17
In the swivel plate positioning sleeve in the left side on plate, then lathe turntable is rotated again to some angle, and one face of product can be processed at this time
On all such space angle holes.After all such space angle hole machineds are complete, made by Machine-Tool Control limit power source 21
Gag lever post 28 rises, while positioning power source 17 drives the swivel plate positioning sleeve in the left side on the disengaging swivel plate 2 of locating rod 26, so
Rotating power source 13 retracts afterwards, drives product fixed part to do clockwise movement together, stops after encountering gag lever post 28, this
When positioning power source 17 drive locating rod 26 to move upwards, then position the swivel plate positioning sleeve placed in the middle that is raised on swivel plate
In, lathe turntable stops after rotating to certain another angle again at this time, then all such skies on processable another face of product
Between angle hole.Finally, being determined by the swivel plate placed in the middle that Machine-Tool Control positioning power source 17 drives locating rod 26 to be detached from swivel plate 2
Position set, rotating power source 13 move forward to stop motion after a upper angle limit with carry-over bar, and limit power source 21 drives
Gag lever post 28 moves downward until stopping when can not limiting swivel plate, turn spur is done always rotating power source 13 again at this time
Clockwise movement, until meeting another rotation angle limited block, the locating rod 26 that is connected on positioning power source 17 at this time
It moves upwards, then navigates in the swivel plate positioning sleeve on the right side on swivel plate, lathe turntable rotation at this time is a certain to the end
Stop after a angle, completes the processing in the space angle hole of workpiece third position.It in this process, can also be on converted products
Other positions, no details will be provided herein.Behind the space angle hole for processing third position, the entire space angle of product
The processing tasks in hole are completed, then circulation above operation when replacing another product.
From the point of view of the information provided according to above-mentioned technical solution, the invention structural stratification orderliness is clear, and fixture assembly is simple,
Positioning accuracy is high, smooth when rotation due to being allowed to rotate using high-precision arc formula rolling guide, running accuracy is high, meets
Segment space angle hole and the processing of other positions of product can be completed on same set of clamping device (fixture), and the invention can not only
The investment for enough saving product machining mechanism, lowers the investment of space angle hole fixture, additionally it is possible to greatly improve the production of product
Efficiency.
