Abstract
The utility model relates to an outer hexagonal screw sword that has location antiskid function based on magnetic current becomes effect. A take place for working as the screwdriver is screwed up or when loosening the bolt, thereby prevents to produce the phenomenon that relative slippage destroyed the bolt head because of exert oneself too quickly screwdrivers blade of leading to and bolt head . the device comprises shell, magnetorheological suspensions, cage ring, solenoid, piston, sealing washer, piston rod, horizontal pole, connecting rod, supporting rod, outer hexagonal screw tool bit, volume -compensating ware, slider, button, spout. After outer hexagonal screw tool bit stretches into the bolt head, sliding block up for the bolt head is tightly carried to the supporting rod, then makes screwdrivers blade, bolt head, supporting rod three not produce relative slippage when twisting the screwdriver according to the knob down circular telegram, is guaranteeing finally that the bolt head does not have to tighten or unclamp the bolt under the circumstances of fish tail, and it cuts off the power supply and then press the knob down once more, and down sliding block makes the supporting rod unclamp the bolt head, accomplishes wholely to tighten or unclamp the bolt process.
Description
Technical field
The utility model relates to the outer-hexagonal screwdriver with anti-slip positioning shifting function, especially relates to the outer-hexagonal screwdriver with anti-slip positioning shifting function based on magnetic rheology effect.
Background technology
In the assembling process of component of machine; major part parts are all bolted; often can there is such situation: staff is when tightening or unclamping bolt; screwdriver head and bolt head generation Relative sliding; bolt head can be caused to be worn and torn by screwdriver head when bolt head insufficient strength, finally cause the awkward situation of twisting not tight or Song Bukai.For preventing the generation of this situation, the utility model utilize magnetic flow liquid have reaction rapidly, continuously, reversible, shear yield stress is high, consume energy the feature such as low, it is combined with the frame for movement of screwdriver, designs a kind of outer-hexagonal screwdriver with anti-slip positioning shifting function.
Utility model content
The technical problems to be solved in the utility model is to provide the outer-hexagonal screwdriver with anti-slip positioning shifting function based on magnetic rheology effect.
In order to effectively solve the deficiency as above of outer-hexagonal screwdriver, the utility model realizes as follows: this device is by shell, magnetic flow liquid, cage ring, solenoid, piston, sealing ring, piston rod, cross bar, connecting rod, supporting rod, outer-hexagonal driver bit, pressurizer, slide block, button, chute forms.Its internal structure is: piston has groove, and solenoid is around wherein; Shell upper end has admittance rail, and lower end has semiclosed guide rail, and guide rail bottom is provided with pressurizer, and piston rod and this two guide rails at piston two ends coordinate slippage, and are coordinated by sealing ring between them; Shell, piston rod, sealing ring form a closed chamber, and magnetic flow liquid is sealed in wherein; Solenoid is isolated by cage ring and magnetic flow liquid; Piston rod and cross bar are connected, and the connected mode of cross bar and connecting rod and connecting rod and supporting rod is hinge-connection; Shell has chute, and slide block and piston are connected, and drives the upper and lower slippage of piston by slide block, and button is arranged on above slide block, controls the break-make of solenoid current.
After outer-hexagonal driver bit stretches into bolt head, up sliding slider, thus drive piston upwards slippage, pass through piston rod, cross bar, the transmission of connecting rod, supporting rod is finally made tightly to clamp bolt head, then press the button, solenoid energising makes driver bit, bolt head, supporting rod three does not produce Relative sliding when tightening or unclamp bolt, finally tighten when ensureing that bolt head does not scratch or unclamp bolt, next again press the button and make solenoid power-off, sliding down movable slider makes supporting rod unclamp bolt head, complete and wholely tighten or unclamp bolt process.
The good effect with the outer-hexagonal screwdriver of anti-slip positioning shifting function based on magnetic rheology effect described in the utility model is: utilize magnetic flow liquid have reaction rapidly, continuously, reversible, shear yield stress is high, consume energy the feature such as low, it is combined with the frame for movement of screwdriver, designs a kind of outer-hexagonal screwdriver with anti-slip positioning shifting function.Magnetic flow liquid volume required in whole device only has 7mL, and shear yield stress can reach 300Mp, and therefore, closely, rapidly, reliability is high, low cost for workable, response for whole apparatus structure.
Accompanying drawing explanation
Fig. 1 be based on magnetic rheology effect there is the fishbolt head of the outer-hexagonal screwdriver of anti-slip positioning shifting function time structural representation.
Fig. 2 be based on magnetic rheology effect have the outer-hexagonal screwdriver of anti-slip positioning shifting function unclamp bolt head time structural representation.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
Composition graphs 1 and Fig. 2, the utility model is based on the outer-hexagonal screwdriver with anti-slip positioning shifting function of magnetic rheology effect, and this device is made up of shell 1, magnetic flow liquid 2, cage ring 3, solenoid 4, piston 5, sealing ring 6, piston rod 7, cross bar 8, connecting rod 10, supporting rod 11, outer-hexagonal driver bit 12, pressurizer 14, slide block 15, button 16, chute 17.Its internal structure is: piston 5 has groove, and solenoid 4 is around wherein; Shell 1 upper end has admittance rail, and lower end has semiclosed guide rail, and guide rail bottom is provided with pressurizer 14, and piston rod 7 and this two guide rails at piston 5 two ends coordinate slippage, and are coordinated by sealing ring 6 between them; Shell 1, piston rod 7, sealing ring 3 form a closed chamber, and magnetic flow liquid 2 is sealed in wherein; Solenoid 4 is isolated by cage ring 3 and magnetic flow liquid 2; Piston rod 7 and cross bar 8 are connected, and cross bar 8 is hinge-connection 9 with the connected mode of connecting rod 10 and connecting rod 10 and supporting rod 11; Shell 1 has chute 17, and slide block 15 and piston 5 are connected, and drive piston about 5 slippage by slide block 15, and button 16 is arranged on above slide block 15, controls the break-make of solenoid 4 electric current.
Utilize magnetic flow liquid 2 have reaction rapidly, continuously, reversible, shear yield stress is high, consume energy the feature such as low, it is combined with the frame for movement of screwdriver, designs a kind of outer-hexagonal screwdriver with anti-slip positioning shifting function.Magnetic flow liquid volume required in whole device only has 7mL, and shear yield stress can reach 300Mp, and therefore, closely, rapidly, reliability is high, low cost for workable, response for whole apparatus structure.
After outer-hexagonal driver bit 12 stretches into bolt head 13, up sliding slider 15, thus drive piston 5 upwards slippage, by piston rod 7, cross bar 8, the transmission of connecting rod 10, supporting rod 11 is finally made tightly to clamp bolt head 13, then 16 are pressed the button, solenoid 4 energising makes driver bit 12, bolt head 13, supporting rod 11 three does not produce Relative sliding when tightening or unclamp bolt, finally tighten when ensureing that bolt head 13 does not scratch or unclamp bolt, next again pressing the button 16 makes solenoid 4 power-off, sliding down movable slider 15 makes supporting rod 11 unclamp bolt head 13, complete and wholely tighten or unclamp bolt process.
