Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1-Figure 3, a kind of embodiment for combing scouring machine index table location locking mechanism is provided.Fig. 2 is Fig. 1
In A-A cross-sectional view；Fig. 3 is the C-C cross-sectional view in Fig. 1.
In Fig. 2, that is, view A-A, with the main shaft 2 being arranged inside shell 1 and shell 1, there are oilhole, worm gear on shell 1
It is fixed on main shaft 2 by flat key and locknut, mandrel 5 is connected by screw on main shaft 2, worm screw 4 and worm gear engagement, 4 band of worm screw
Dynamic worm gear and main shaft 2 rotate, and main shaft 2 is rotated with moving mandrel 5, and that realizes comb teeth workpiece divides tooth to move, not due to worm gear and worm screw 4
It is evitable there are sideshake, cause workpiece during comb teeth that can constantly carry out back rotation, machining accuracy influenced, in such case
Under, it is necessary to main shaft 2 is locked in consideration, prevents workpiece when processing from rotating.
To scheme in C-C, i.e. Fig. 3,2 retaining mechanism of main shaft is installed on shell 1,8 lid 6 of piston is mounted on shell 1 by screw,
Piston rod 12 is connected on piston 8, disc spring 7 is socketed on piston rod 12, and piston 8 is mounted on shell 1 by disc spring 7 and 8 lid 6 of piston
Hole in, pressing plate 9 is mounted on piston rod 12 by screw, and pressing plate 9 and 5 end face of mandrel fit closely.
When work, hydraulic station, to fuel feeding in 1 hole of shell, pushes piston 8 to compress disc spring 7 by fuel feed hole 11, make pressing plate 9 with
5 end face of mandrel is detached from, at this point, worm screw 4 drives worm gear and mandrel 5 to rotate, is realized that workpiece divides tooth, is divided after the completion of tooth, hydraulic station unloads
Oil, under the action of disc spring 7, piston 8 is moved with dynamic pressure plate 9, and pressing plate 9 is made to compress 5 end face of mandrel, is realized that mandrel 5 is locked, is prevented
