Abstract

The utility model relates to a clamp for a lock key copying machine with a changeable sectional jaw, which comprises a bottom seat which is provided with a long and narrow slot channel, and two sets of a movable jaw and a fixed jaw which can make relative movement on the long and narrow slot channel, wherein two sets of parallel guide rods and a middle spring screw rod set are respectively fixed or penetrated through both sides of the movable jaw and the fixed jaw for making the movable jaw do straight line relative movement toward the fixed jaw on the long and narrow slot channel, sectional jaws which are locally divided into blocks are fixed on the opposite tops of the fixed jaw and the movable jaw in a detachable mode to form a clamping part for clamping a prototype lock key or a key billet, when the sectional jaw is damaged accidentally, a new product can be easily used for replacement.

Description

Machine for reproducing keys anchor clamps with replaceable piecemeal jaw

Technical field

The utility model is about a kind of anchor clamps that are applicable to Machine for reproducing keys, especially refer on a kind of swinging jaw and the relative top of fixed jaw at anchor clamps, that can dismantle is fixed with relative piecemeal jaw, to constitute the clamping part of anchor clamps, when the piecemeal jaw is subjected to accidental destruction, can replacing new product easily, and constitute the Machine for reproducing keys anchor clamps with replaceable piecemeal jaw.

Background technology

The general Machine for reproducing keys structure of anchor clamps, mostly constitute shown in the 3rd figure of No. 180413 patent announcement cases in China Taiwan, mainly be to utilize screwing togather of a driving screw and a swinging jaw, and the guiding of the shaggy block fit of swinging jaw and fixed jaw drive swinging jaw.Yet the driving screw length of this kind anchor clamps, be that more concavo-convex fit is partly long a lot of on ratio, and because the cause of manufacturing tolerance, the mobile of swinging jaw can produce skew slightly, so can cause can't be accurately between swinging jaw and the fixed jaw, effective lamellar key of clamping or spoon embryo, that is the upwards skew of swinging jaw can be pushed up a lamellar key or a spoon embryo are upturned, and can't concordant really being clamped, so that the depth precision of the cutting spoon embryo of cutter is duplicated in influence, and easily cause duplicating the clamping end that is cut to swinging jaw and fixed jaw unexpectedly of cutter, and damage swinging jaw and fixed jaw.Surpassed 1/3rd when above if the clamping end of swinging jaw and fixed jaw damages, though other part of all the other component parts or anchor clamps is still intact, whole anchor clamps also become and can't bear use.Again, for the guiding that relatively moves smoothly of the swinging jaw that makes mutual fit and fixed jaw, must reserve long recess space, therefore when duplicating cutter when cutting spoon embryo, the tiny smear metal meeting of getting off of cutting is fallen in the recess space, and the tiny smear metal of this kind has oil stain, meeting sticks tightly and accumulates in the interior edge of groove, be difficult to remove, and work as the smear metal of being accumulated more and more for a long time, promptly can hinder or make to relatively move more and more little or deflection between swinging jaw and the fixed jaw, cause clamping key or spoon embryo that the swinging jaw and the clamping end of fixed jaw can't be concordant.

The utility model content

The utility model is improved at the shortcoming of above-mentioned prior art, and the clamping end that a kind of swinging jaw of the anchor clamps that will be subjected to duplicating the unexpected cutting of cutter easily and damage and fixed jaw are provided is blocked into the piecemeal jaw of smaller piece, and being placed on the lengthwise L type block that is molded on the top of swinging jaw and fixed jaw of can dismantling respectively, and the dual-side parallel guide rod and the middle springs screw rod group that cooperate two groups of fixing respectively or break-through swinging jaw and fixed jaws, the straight line of deflection relatively moves to make swinging jaw do not facing to fixed jaw, to constitute the Machine for reproducing keys anchor clamps with replaceable piecemeal jaw, when seriously damaging to be subjected to the unexpected cutting of cutter when the piecemeal jaw, can be only with the piecemeal jaw of this smaller piece part new product that changed the outfit, and will do not changed by whole swinging jaw or fixed jaw, to save cost.

Fig. 1 is the perspective view that expression the utlity model has the Machine for reproducing keys of replaceable piecemeal jaw.

Fig. 2 is the part section top view that expression the utlity model has the Machine for reproducing keys of replaceable piecemeal jaw.

Fig. 3 is the part section front view that expression the utlity model has the Machine for reproducing keys of replaceable piecemeal jaw.

The specific embodiment

As Figure 1-3, it is Machine for reproducing keys one of the anchor clamps specific embodiment that expression the utlity model has replaceable piecemeal jaw, it comprises: a base 1 has a thin-and-long conduit 11, be used for being placed in a Machine for reproducing keys duplicate cutter and guide pin under or contiguous part (not shown); Can on the thin-and-long conduit, make the swinging jaw 2 and the fixed jaw 3 that relatively move for two groups; The dual-side parallel guide rod 4 and a middle springs screw rod group 5 of two groups of fixing respectively or break-through swinging jaw and fixed jaws, so that swinging jaw 2 can be followed the guiding of dual-side parallel guide rod 4, and utilizing the rotation of the screw rod 51 of middle springs screw rod group 5, the straight line of deflection relatively moves and do not facing to fixed jaw 3 on thin-and-long conduit 11.Screw togather one handle 52 on one end of screw rod 51, be used for rotating screw bolt.

As described above, the utility model can keep the optimum state of really effective clamping key or spoon embryo at any time in order to make the relative swinging jaw 2 and the clamping end of fixed jaw 3, the clamping end is blocked into the piecemeal jaw 21 of smaller piece, 31, but keep the clamping width constant, and utilize countersink head screw 6 with its locking in a lengthwise L type block portion 22 that is molded on the top of swinging jaw 2 or fixed jaw 3, on 32, to constitute the clamping part of anchor clamps, be used for the spoon embryo that clamping one prototype key or desires to duplicate, with when carrying out the replication work of key, the piecemeal jaw 21 of smaller piece, 31 are subjected to duplicating the unexpected cutting of cutter and when seriously damaging, can revolve and move back countersink head screw 6, and the new product that only the piecemeal jaw of this smaller piece part changed the outfit will not changed by whole swinging jaw or fixed jaw, so that do not influence the replication work of key, and then save cost.Because lengthwise L type block portion 22,32 have mutual rectangular vertical plane and horizontal plane, therefore can be convenient to piecemeal jaw 21,31 is honest in holding and locking at lengthwise L type block 22, on 32, cooperate two groups of fixing respectively or the dual-side parallel guide rod 4 of break-through swinging jaw and fixed jaw and settings of a middle springs screw rod group 5 again, can make swinging jaw face toward fixed jaw and do not that the straight line of deflection relatively moves, to reach really the purpose of effective clamping key or spoon embryo.

Claims

1. Machine for reproducing keys anchor clamps with replaceable piecemeal jaw, it is characterized in that these anchor clamps comprise: a base has a thin-and-long conduit; Can on this thin-and-long conduit, make the swinging jaw and the fixed jaw that relatively move for two groups; The dual-side parallel guide rod and a middle springs screw rod group of two groups of fixing respectively or this swinging jaw of break-through and fixed jaws, the straight line of deflection relatively moves so that this swinging jaw can be done not facing to this fixed jaw on this thin-and-long conduit; On the relative top of this swinging jaw and fixed jaw, the piecemeal jaw that is fixed with a relative local piecemeal that can dismantle respectively is to constitute a clamping part.

2. the Machine for reproducing keys anchor clamps with replaceable piecemeal jaw according to claim 1, it is characterized in that, on the relative top of this fixed jaw and swinging jaw, form a lengthwise L type block portion respectively so that with this piecemeal jaw honest by holding and being fixed thereon.
