Description
Technical field
The present invention relates to the clamping of a kind of workpiece or cutter, supporting, positioner, is specifically related to a kind of clamping device being convenient to processing work circumference.
Background technology
The clamping device of instrument lathe mainly adopts the relative sliding of the elastic jacket conical surface and spindle taper hole to carry out clamping work pieces.At main shaft tail end, the cylinder lever connecting rod on driving chuck moves backward and the resilience of elastic jacket self clamps and loosens workpiece, can change the size of clamping force.Change the elastic jacket of different inner diameters, the processing of different-diameter part can be adapted to.
Existing above-mentioned clamping device is after holding workpiece, and the angle of workpiece cannot adjust, so for the situation wanting processing work circumference, as offered the groove of circumference on axle, then first workpiece to be unclamped, again clamp after turning of work piece, then other angles of workpiece be processed.
Summary of the invention
For the defect that above-mentioned prior art exists, the object of the present invention is to provide a kind of clamping device being convenient to processing work circumference, this clamping device can processing work be circumferential once.
For achieving the above object, technical scheme of the present invention is:
Be convenient to the clamping device of processing work circumference, comprise motor, support, the main shaft of hollow, pull bar and collet, described main shaft two ends are rotatably connected on support, main shaft one end forms the taper hole of enlarging shape, described collet forms the clamping hole of hollow, described drag link sleeve is located in main shaft, described collet is connected to pull bar near taper hole one end, and collet coordinates with taper hole inclined-plane, described pull bar stretches out main shaft away from taper hole one end, wherein, also be provided with belt pulley, regular way is blue, slide, slide block, disc spring and eccentric shaft, described motor output end and main shaft are equipped with belt pulley, both pass through belt transmission, orchid is connected with support regular way, slide and long Flange joint, described slide block and slide are slidably connected, slide block side and tie rod end offset, the side that pull bar stretches out main shaft is enclosed within outside described disc spring, disc spring one end is fixed on pull bar, the other end and main shaft one end offset, described eccentric shaft and slide are rotationally connected, and eccentric shaft surface offsets away from pull bar side with slide block.
When adopting technique scheme, when preparing holding workpiece, first eccentric rotation axis, when making eccentric shaft apart from larger side and shoe contact, eccentric shaft pushing drawing rod moves towards main shaft side, the side of main shaft is stretched out owing to being enclosed within pull bar outside disc spring, disc spring one end is fixed on pull bar, the other end and main shaft one end offset, so disc spring is compressed, and collet becomes releasing orientation from being extruded by spindle taper hole, then workpiece is inserted in the clamping hole of collet, and then eccentric rotation axis, make eccentric shaft apart from less side and shoe contact, now, disc spring is recovered, drive pull bar towards moving away from main shaft side, because collet is connected with pull bar, and collet coordinates with spindle taper hole inclined-plane, so collet is extruded, collet shrinks and piece-holder is lived, starter motor, because the output of motor and main shaft are equipped with belt pulley, and both are by belt transmission, so driven by motor main shaft rotates, now, just can process the circumference of workpiece.Piece-holder can not only be lived by the present invention, and can pacify by rotational workpieces, and institute is so that processing circumference.
Further, described pull bar is provided with away from the position of main shaft one end the round nut be connected with pull rod screw in disc spring.Regulate round nut in pull rod shaft position upwards, thus regulate the decrement of disc spring, and chucking power during final control holding workpiece.
Further, described belt pulley is connected with main shaft key.The mode of this connection is convenient to installation and removal.
Further, described main shaft two ends are rotationally connected respectively by bearing and support.Resistance in main axis process is little, and also very little to the wearing and tearing of main shaft.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that the clamping device embodiment of processing work circumference is convenient in 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: support 1, pull bar 2, main shaft 3, collet 4, clamping hole 41, belt wheel 5, bearing 6, regular way orchid 7, round nut 8, slide block 9, eccentric shaft 10, slide 11, disc spring 12.
As shown in Figure 1, a kind of clamping device being convenient to processing work circumference, comprise motor, support 1, the main shaft 3 of hollow, pull bar 2 and collet 4, main shaft 3 two ends are rotatably connected on support 1, main shaft 3 one end forms the taper hole of enlarging shape, collet 4 forms the clamping hole 41 of hollow, pull bar 2 is sheathed in main shaft 3, collet 4 is connected to pull bar 2 near taper hole one end, and collet 4 coordinates with taper hole inclined-plane, pull bar 2 stretches out main shaft 3 away from taper hole one end, wherein, also be provided with belt pulley 5, regular way orchid 7, slide 11, slide block 9, disc spring 12 and eccentric shaft 10, motor output end and main shaft 3 are equipped with belt pulley 5, both pass through belt transmission, regular way blue 7 is connected with support 1, slide 11 is connected with regular way blue 7, slide block 9 and slide 11 are slidably connected, slide block 9 side and pull bar 2 end offset, the side that pull bar 2 stretches out main shaft 3 is enclosed within outside disc spring 12, disc spring 12 one end is fixed on pull bar 2, the other end and main shaft 3 one end offset, eccentric shaft 10 and slide 11 are rotationally connected, and eccentric shaft 10 surface offsets away from pull bar 2 side with slide block 9.
Pull bar 2 is provided with away from the position of main shaft 3 one end the round nut 8 be threaded with pull bar 2 in disc spring 12.Regulate round nut 8 in pull bar 2 position axially, thus regulate the decrement of disc spring 12, and chucking power during final control holding workpiece.
