Description
Technical field
The utility model relates to the clamping of a kind of workpiece or cutter, and supporting, positioner, is specifically related to a kind of disc spring clamp system.
Background technology
The clamping device of instrument lathe mainly adopts the relative sliding of the collet 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 collet self clamps and loosens workpiece, can change the size of clamping force.Change the collet of different inner diameters, the processing of different-diameter part can be adapted to.
Existing clamping device passes through manpower, cylinder or hydraulic cylinder etc. as power source when holding workpiece, drive cylinder lever connecting rod, thus drives collet to move, thus by Workpiece clamping.In the process of processing workpiece, owing to driving the dynamic instability of pull bar, so easily there is the phenomenon loosened in workpiece.
Utility model content
For the defect that above-mentioned prior art exists, the purpose of this utility model is the disc spring clamp system providing a kind of holding workpiece stable.
For achieving the above object, the technical solution of the utility model is:
Disc spring clamp system, comprise pedestal, the main shaft of hollow, pull bar and collet, described main shaft is fixed on pedestal, main shaft one end is 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 flange extension, end cap, slide block, disc spring and eccentric shaft, flange extension is connected with pedestal, end cap is connected with flange extension, described slide block and end cap 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 end cap 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.In the utility model, when being in holding workpiece state, the power of its clamping is provided by disc spring, not provided by manpower, cylinder or hydraulic cylinder, the power that disc spring is applied on pull bar is more stable, so when processing work, there will not be the phenomenon that workpiece loosens.
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 the position of round nut on pull bar, just can regulate the decrement of disc spring, thus chucking power when controlling holding workpiece.
Further, described eccentric shaft is provided with bearing, and this bearing and slide block offset.During eccentric rotation axis, bearing and slide block offset, and friction is between the two little, so the time that can use is long.
Further, described eccentric shaft is provided with handler.By handler eccentric rotation axis, add the moment of rotation, eccentric rotation axis is more laborsaving.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model disc spring clamp system embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
As shown in Figure 1, a kind of disc spring clamp system, comprise pedestal 1, the main shaft 2 of hollow, pull bar 3 and collet 4, main shaft 2 is fixed on pedestal 1, main shaft 2 one end is the taper hole of enlarging shape, collet 4 forms the clamping hole 41 of hollow, pull bar 3 is sheathed in main shaft 2, collet 4 is connected to pull bar 3 near taper hole one end, and collet 4 coordinates with taper hole inclined-plane, pull bar 3 stretches out main shaft 2 away from taper hole one end, wherein, also be provided with flange extension 5, end cap 6, slide block 9, disc spring 7 and eccentric shaft 10, flange extension 5 is connected with pedestal 1, end cap 6 is connected with flange extension 5, slide block 9 and end cap 6 are slidably connected, slide block 9 side and pull bar 3 end offset, the side that pull bar 3 stretches out main shaft 2 is enclosed within outside disc spring 7, disc spring 7 one end is fixed on pull bar 3, the other end and main shaft 2 one end offset, eccentric shaft 10 and end cap 6 are rotationally connected, and eccentric shaft 10 surface offsets away from pull bar 3 side with slide block 9.
In the present embodiment, pull bar 3 is provided with away from the position of main shaft 2 one end the round nut 8 be threaded with pull bar 3 in disc spring 7.Regulate the position of round nut 8 on pull bar 3, just can regulate the decrement of disc spring 7, thus chucking power when controlling holding workpiece.
Eccentric shaft 10 is provided with bearing, and this bearing and slide block 9 offset.During eccentric rotation axis 10, bearing and slide block 9 offset, and friction is between the two little, so the time that can use is long.
Eccentric shaft 10 is provided with handler 11.By handler 11 eccentric rotation axis 10, add the moment of rotation, eccentric rotation axis 10 is more laborsaving.
Specific works principle:
When preparing holding workpiece, first eccentric rotation axis 10, when the larger side of eccentric shaft 10 eccentric throw is contacted with slide block 9, eccentric shaft 10 pushing drawing rod 3 moves towards main shaft 2 side, owing to being enclosed within the side that pull bar 3 stretches out main shaft 2 outside disc spring 7, disc spring 7 one end is fixed on pull bar 3, the other end and main shaft 2 one end offset, so disc spring 7 is compressed, and collet 4 becomes releasing orientation from being extruded by main shaft 2 taper hole, then workpiece is inserted in the clamping hole 41 of collet 4, and then eccentric rotation axis 10, the less side of eccentric shaft 10 eccentric throw is contacted with slide block 9, now, disc spring 7 is recovered, pull bar 3 is driven to move towards away from main shaft 2 side, because collet 4 is connected with pull bar 3, and collet 4 coordinates with main shaft 2 taper hole inclined-plane, so collet 4 is extruded, collet 4 shrinks and piece-holder is lived.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
