Description
Technical field
The present invention relates to a kind of belt pulley fixed axis tool for drilling.
Background technology
Belt transmission is a kind of kind of drive be in daily use, and in belt transmission, belt pulley and its fixed axis are very common.
Usually also need between belt pulley with belt pulley fixed axis to hole and by holding screw by belt pulley and the fixed axis fixation of belt road in belt pulley fixed axis circumference except key is connected.
When the circumference boring to belt pulley fixed axis, inventor encounters problem, clamping tool of the prior art often fixes insecure when clamping belt pulley fixed axis or operation is too complicated, and these not only have impact on machining accuracy, and have impact on production efficiency.
Summary of the invention
The invention is intended to provide a kind of belt pulley fixed axis tool for drilling, to enhance productivity.
Belt pulley fixed axis tool for drilling in this programme, comprise pedestal, also comprise eccentric wheel, lever, V-block, drill bushing and rest pad, pedestal is provided with the supporting arm of C shape, supporting arm back side pivot joint eccentric wheel, its intermediate part is hubbed on supporting arm lower end, rest pad is positioned at the belly of supporting arm, rest pad lower end is the bar portion be slidably connected with supporting arm, bar subordinate end is against lever right-hand member, bar portion cover has the spring connecting lever right-hand member and supporting arm, lever left end can offset with eccentric wheel wheel rim, the anti-rotation groove along glide direction is provided with in the middle part of bar portion, supporting arm sidewall is provided with the anti-turn screw inserting anti-rotation groove, supporting arm upper end connects bushing plate, bushing plate is provided with V-block, V-block is positioned at directly over rest pad, V-block center is embedded with drill bushing.
Axis and the eccentric geometrical axis at eccentric shaft axis and pivoting point place are inconsistent.
Compared with prior art, the invention has the advantages that: during work, workpiece is put on rest pad, then eccentric wheel is rotated, eccentric wheel moves down against lever left end, and lever right-hand member moves, thus makes rest pad holder workpiece to move to V-block, and together with V-block clamping work pieces, then drill bit is through drill bushing processing work, after machining, only need operate eccentric wheel and rotate backward, lever right-hand member moves down reset under the action of the spring, and rest pad moves down and unclamps workpiece.This programme convenient mounting and clamping is quick, processing ease, can fast pulley fixed axis fast, substantially increases production efficiency.
Further, be connected by screw fixing between bushing plate and supporting arm, facilitate installing/dismounting.
Further, lever left end screw connects push rod, and push rod upper end and eccentric wheel wheel rim offset, and push rod lower end is threaded with lever left end, and convenient adjustment push rod stretches out the height of lever left end, thus adjustment clamping degree and gripping range.
Further, V-block is provided with positioning boss, and on bushing plate, correspondence is provided with counterbore, is fixed between V-block and bushing plate by screw, is convenient to fixedly secure V-block.
Further, be also provided with lining between bar portion and supporting arm, lining can reduce the frictional force between bar portion and supporting arm, and spring one end is connected to lining bottom surface, and the spring other end is against lever right-hand member end face, and spring can make lever reset, rest pad unclamps workpiece.
Further, eccentric wheel is provided with handle, conveniently rotates eccentric wheel.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: eccentric wheel 1, lever 2, V-block 3, drill bushing 4, rest pad 5.
Embodiment is substantially as shown in Figure 1: belt pulley fixed axis tool for drilling comprises pedestal, also comprise eccentric wheel 1, lever 2, V-block 3, drill bushing 4 and rest pad 5, pedestal is provided with the supporting arm of C shape, supporting arm back side pivot joint eccentric wheel, eccentric wheel is provided with handle, conveniently rotate eccentric wheel, its intermediate part is hubbed on supporting arm lower end, rest pad is positioned at the belly of supporting arm, rest pad lower end is the bar portion be slidably connected with supporting arm, also lining is provided with between bar portion and supporting arm, lining can reduce the frictional force between bar portion and supporting arm, spring one end is connected to lining bottom surface, the spring other end is against lever right-hand member end face, spring can make lever reset, rest pad unclamps workpiece, bar subordinate end is against lever right-hand member, bar portion cover has the spring connecting lever right-hand member and supporting arm, lever left end screw connects push rod, push rod upper end and eccentric wheel wheel rim offset, push rod lower end is threaded with lever left end, convenient adjustment push rod stretches out the height of lever left end, thus adjustment clamping degree and gripping range, the anti-rotation groove along glide direction is provided with in the middle part of bar portion, supporting arm sidewall is provided with the anti-turn screw inserting anti-rotation groove, supporting arm upper end connects bushing plate, be connected by screw fixing between bushing plate and supporting arm, facilitate installing/dismounting, V-block is provided with positioning boss, on bushing plate, correspondence is provided with counterbore, fixed by screw between V-block and bushing plate, be convenient to fixedly secure V-block, V-block is positioned at directly over rest pad, V-block center is embedded with drill bushing.
