Description
Technical field
The utility model relates to technical field of engineering machinery, particularly about a kind of screw disassembling tool.
Background technology
Transfer printing board (claims again relief printing plate, soft version, post skin, in written word, be often called APR version, because the trade mark of Japanese Asahi Kasei Corporation is gained the name) be a kind of plate body that ultraviolet curing polyurethanes resin makes as raw material of take, it is used on the printing cylinder in alignment films printing equipment.During printing, first oriented material solution is transferred to being pre-formed in the APR version of figure, by APR version, orientation liquid is printed onto to for example surface of glass substrate afterwards and forms alignment films.
When APR version is attached on printing cylinder, also need the leading edge that clamps APR version with an APR version clamping element to be fixed on printing cylinder, Figure 1 shows that a kind of schematic diagram of APR version clamping element.As shown in Figure 1, APR version clamping element 30 comprises clamping element 31 and lower clamping element 32, APR version 40 is located between clamping element 31 and lower clamping element 32, the hole (not shown) that screw 33 passes of allowing in APR version 40 is alignd with the screw 321 on lower clamping element 32, upper clamping element 31 is provided with counter sink 311, screw 33 is through locking in the screw 321 of lower clamping element 32 after the hole in counter sink 311 and APR version 40, thereby upper clamping element 31 and lower clamping element 32 are fixed together, and the screw 33 conventionally adopting in APR version clamping element 30 is soket head cap screw.Because APR version 40 possesses certain elasticity, when the screw upper clamping element 31 of 33 locking and lower clamping element 32, the screen resilience of APR version 40 can make clamping element 31 and lower clamping element 32 have the trend that both sides separate up and down, and because the afterbody of screw 33 is locked in the screw 321 of lower clamping element 32, the head of screw 33 is locked in the counter sink 311 on clamping element 31, thereby the afterbody of screw 33 is subject to the downward pulling force of lower clamping element 32 to its generation, the head of screw 33 is subject to the pulling force that make progress of clamping element 31 to its generation, make between screw 33 and upper clamping element 31 and lower clamping element 32 contact tightr, therefore, when using inner hexagon spanner knockout screw 33, the frictional force of the contact position between screw 33 and upper clamping element 31 and lower clamping element 32 increases, inner hexagon spanner need to apply that enough large torsion can overcome above-mentioned frictional force and screw 33 is removed screw 33.Therefore, repeatedly installing, dismantling for a long time in the process of APR version clamping element 30, easily cause the part of periphery of inner hexagonal hole of screw 33 because of damaging compared with large torsion that inner hexagon spanner repeatedly applies it, cause re-using inner hexagon spanner and removed.When the inner hexagonal hole damage of the head because of screw 33 cannot be used spanner dismounting, conventionally use the modes such as saw, burr, punching that screw 33 heads are changed into " one " font, in the bottom surface of the inner hexagonal hole of screw 33, make the groove of " one " font, then removed with screwdriver.Yet, because screw 33 is located in the counter sink 311 of upper clamping element 31, screw 33 is sawed, file, during the operation such as punching inevitably can on clamping element 31 damaging property damages, cause shorten the service life of APR version clamping element 30.
