Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in the figure, crankshaft grinder center frame, comprise centre frame base 1, the side, bottom of described centre frame base 1 is provided with gear 2, gear 2 engages with the tooth bar 4 on grinding machine 3, the top of described centre frame base 1 is connected with left-hand screw bar 6 by bearing block 5, left-hand screw bar 6 one end is connected with joystick 7, left-hand screw bar 6 is connected with back shaft A8, described back shaft A8 is provided with bistrique 15, described bearing block 5 and joystick 7 are by round nut 9, bearing 10 connects, index dial 11 is provided with between round nut 9 and bearing 10, the interior bottom portion side of described centre frame base 1 is provided with central frame body 12, the inclined-plane of described central frame body 12 is provided with slide block 13, described slide block 13 surface support has back shaft B14, described back shaft B14 is provided with bistrique 15, the side of described centre frame base 1 is provided with manual setter 16, manual setter 16 is connected with slide block 13 by right handed worm 17.
Described manual setter 17 comprises joystick 7, round nut 9, bearing 10, index dial 11, bearing block 5, bearing block 5 is fixed on centre frame base 1, described bearing block 5 is connected by round nut 9, bearing 10 with joystick 7, is provided with index dial 11 between round nut 9 and bearing 10.
Described slide block 13 is trapezium structure, and described slide block 13 offers right handed worm connector 18.
Described central frame body 12 is trapezium structure, and the bottom of described central frame body 12 offers groove 19, can be fixed on grinding machine 3.
The utility model in use, first uses spanner transmitting gear 2, drives central frame body 12 to the trunnion position of required processing; Rotate left-handed screw 6 by hand joystick 7, screw rod drives back shaft A8 side-to-side movement.While grinding, turn clockwise joystick 7, supports workpiece, thus realize horizontal direction support; In like manner, when rotating below joystick 7, right handed screw 17 can be with movable slider 13, rises, thus back shaft B14 is moved upward when slide block 13 moves right, and reaches the object supporting workpiece.This mechanical transmission structure operates more laborsaving.In diagram, it is 100mm that center holds adjustment diameter range, and if desired machining spindle neck is less than the crankshaft section of 220mm, then need to change longer bistrique 15.
The utility model rightward space is large, is both applicable to small-diameter grinding wheel, is also applicable to large grinding simultaneously.The large emery wheel of the employing that crank diameter is large, on the contrary use little emery wheel.The crankshaft journal range of work
the workpiece crank length being applicable to processing can reach to largest diameter
the diameter of emery wheel
the width of centre frame only has 80mm, even if the crankshaft type part that axle journal is short, and also can supplemental support; The adjusting range of two back shafts is 0-50mm, need not again because stroke changes bistrique not during fine grinding; Substantially most domestic crankshaft type part grinding fine finishining can be met
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
