Description
Technical field
The utility model relates to technical field of mechanical equipment, particularly a kind of M2120 plain grinding machine internal fixture.
Background technology
Installing workpiece in present production practices is all generally clamped by the scroll chuck of trade union college at lathe, endoporus is ground after corrected gear endoporus and end face run-out, the harm brought like this is complex operation, because gear after heat treatment has distortion, precision relies on the level of corrections with operator completely, gear beat easily cause defective.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of convenient mounting and clamping, the M2120 plain grinding machine internal fixture that simple to operate, tooth runout is stable.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of M2120 plain grinding machine internal fixture, comprise the main spindle box body of frame-type, main spindle box body two sides have hole, a main shaft protrudes from the two sides of main spindle box body simultaneously through Kong Bing, main shaft inner sleeve has push rod, main shaft left end is fixedly connected with a main shaft adapter sleeve, main shaft adapter sleeve and hydraulic gyration oil cylinder, push rod pierces into hydraulic gyration oil cylinder, pressure change level with hydraulic gyration oil cylinder is twitched, main shaft right-hand member end face is fixedly connected with a thin film chuck, thin film chuck is provided with film, film is evenly equipped with and is no less than 3 jaws.
Improve, described film is also provided with the end face strong point, and the end face strong point supports workpiece, and workpiece outer face is surrounded by steel ball, and steel ball and saves garden and keeps enclosing, thus ensures clamping work pieces.
Improve, described joint garden keeps circle to comprise three parts, the retention tab that the end face veneer of a slice and workpiece is arranged, and retention tab two ends are connected to iron pin respectively, and two iron pins are each passed through the steel ball of upper/lower terminal.
After adopting technique scheme, the utility model tool has the following advantages:
More for convenience, operation is simple than ever for clamping, has well accomplished to control the stable of tooth runout, has improve class's output of workshop.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
Fig. 1 is the utility model generalized section;
Fig. 2 is the generalized section that joint garden of the present utility model keeps circle and workpiece.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, a kind of M2120 plain grinding machine internal fixture, comprise the main spindle box body 1 of frame-type, main spindle box body 1 two sides have hole, a main shaft 1 protrudes from the two sides of main spindle box body 1 simultaneously through Kong Bing, main shaft 1 inner sleeve has push rod 5, main shaft 1 left end is fixedly connected with a main shaft adapter sleeve 3, main shaft adapter sleeve 3 and hydraulic gyration oil cylinder 4, push rod 5 pierces into hydraulic gyration oil cylinder 4, pressure change level with hydraulic gyration oil cylinder 4 is twitched, main shaft 1 right-hand member end face is fixedly connected with a thin film chuck 6, thin film chuck 1 is provided with film 7, film 7 is evenly equipped with and is no less than 3 jaws 8, described film 7 is also provided with the end face strong point 11, the end face strong point 1 supports workpiece 12, workpiece 12 outer face is surrounded by steel ball 10, steel ball 10 and one saves garden and keeps circle 9, thus ensure clamping work pieces 12, described joint garden keeps circle 9 to comprise three parts, the retention tab that the end face veneer of a slice and workpiece 12 is arranged, retention tab two ends are connected to iron pin respectively, two iron pins are each passed through, the steel ball 10 at lower two ends.
During clamping workpiece 12, the pressure of hydraulic control angling cylinder 4, push rod 5 is twitched in main shaft 1 with pressure change, when pressure is large, push rod 5 is gone out, and film 7 is out of shape thus jaw 8 opens, at this moment workpiece 12 is loaded onto, then hydraulic control angling cylinder 4 makes push rod 5 bounce back, and film 7 gets back to original place makes jaw 8 clamping work pieces 12 Shang Jie garden keep circle 9, clamping work pieces 12.It is almost nil that jaw 8 just needs reconditioning voluntarily that the revolution of jaw is beated in installation afterwards.
The utility model has convenient mounting and clamping, simple to operate, the advantage that tooth runout is stable.
Except above preferred embodiment, the utility model also has other embodiment, those skilled in the art can make various change and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the scope that the utility model claims define.
