Description
Technical field
The utility model relates to mechanical manufacturing field, and in particular, the utility model is a kind of quick clamping device about welding clamp.
Background technology
Tank bracket is the main body of power switch cabinet, is the institute of the installation of other electrical equipments.In the production process of welded type tank bracket, because the tank bracket member is numerous, need a large amount of clamping devices, each member location is reliable to keep, the welding deformation of control member and tank bracket.When tank brackets such as XGN12, GG-1A welded, every tank bracket all needed the clamping point about 60.For this reason, when the whole production beam worker in, clamp and to unclamp the shared time proportion of clamping device bigger.Reduce to loosen, tighten the time of anchor clamps, have a significant effect raising labour productivity.
Patent Office of the People's Republic of China has announced a CN2838844Y document on November 22nd, 2006, name is called the weld clamp device, this device comprises that two cards placed side by side are blue, is provided with the rigidity connector between this two cards orchid, and this rigidity connector has at least two stationary planes.Because be provided with the rigidity connector between the two card orchids, this rigidity connector has stationary plane, workpiece to be welded can be fastened between stationary plane and the screw mandrel in use, and workpiece to be welded is fixed.The shortcoming of this device is a complex structure, troublesome poeration.
Summary of the invention
The utility model provides a kind of quick clamping device simple in structure, easy and simple to handle for solving the welding clamp complex structure that exists in the prior art, the shortcoming of troublesome poeration.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises support, handle, clamping head, one end and the support of handle, clamping head are hinged, handle also links to each other by connecting rod with clamping head, one end and the handle of connecting rod are hinged, and the other end and the clamping head of connecting rod are hinged; Support, handle, connecting rod and clamping head are formed a quadric chain, when handle, when clamping head is in clamped condition, the free end of clamping head is close to clamped thing, the hinged line of centres at connecting rod two ends is parallel with the center line of handle and perpendicular with the center line of clamping head.As everyone knows, near the four bar linkage dead points huge reinforcement characteristic is arranged, the characteristic of retaining is arranged again behind the dead point excessively; And these characteristics are in other field prolonged application, be stablize, structure reliably; During welding clamped thing welded part is placed on the welding platen, support is fixedlyed connected with securing member with the welding platen, clamping head is aimed at clamped thing, turning handle, handle rotates clamping head by connecting rod simultaneously, when the free end of clamping head and clamped thing are close to, connecting rod is parallel with the center line of handle and perpendicular with the center line of clamping head, be that quadric chain is in the dead-centre position, at this moment the clamping head lateral pressure very big to clamped deposits yields makes clamped thing and welding bench plate holder tight; Weld the backward rotation handle that finishes, handle drives the clamping head reverse rotation by connecting rod, breaks away from the dead-centre position, and clamping head unclamps clamped thing; Whole operation is very convenient quick, and structure is also very simple.
As preferably, support is provided with a spacing inclined-plane, and when handle, when clamping head is in clamped condition, the end that connecting rod links to each other with clamping head contacts with described spacing inclined-plane.One spacing inclined-plane is set on support, when the clamp operation handle, connecting rod can be rotated to above the dead-centre position and since spacing inclined-plane stop that quadric chain is in more stable lock-out state, make the state safety and reliability of clamping.
As preferably, the free end of clamping head is provided with adjusting device; Adjusting device comprises screw bolt and nut, and an end of bolt passes the free end of clamping head, and fixedly connected by nut; When clamping, the other end of bolt compresses with clamped thing and is connected.Regulate the extension elongation of bolt and can regulate when operating grip is done to clamp rotation the distance of bolt end face when quadric chain reaches the dead-centre position and welding platen surface; Therefore as long as regulate the clamped thing that the extension elongation of bolt just can clamp different-thickness.
As preferably, clamping head is provided with and the corresponding stopper slot of clamped thing towards a side of clamped thing.When clamp operation, there is the component that level is reverse in clamping head in the rotation that clamps, clamped thing is moved horizontally, accurate in order to guarantee clamped thing in horizontal inverted orientation, clamping head towards clamped thing one side establish one with the corresponding stopper slot of clamped thing.
The beneficial effects of the utility model are: simple in structure, easy to operate, accurate positioning, the reliable clamped thing that also can adapt to different-thickness of fastening safety.
Description of drawings
Fig. 1 is a kind of structural representation of the quick clamping device of the utility model when unclamping;
Fig. 2 is a kind of structural representation of the quick clamping device of the utility model when clamping.
Among the figure: 1. handle, 2. connecting rod, 3. support, 4. clamping head, 5 adjusting devices, 6. clamped thing, 7. welding platen, 8. spacing inclined-plane, 9. stopper slot.
The specific embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings the technical solution of the utility model is described in further detail.
Embodiment:
The quick clamping device of present embodiment, referring to Fig. 1, comprise the quadric chain that support 3, handle 1, clamping head 4, connecting rod 2 are formed, one end and the support 3 of handle 1, clamping head 4 are hinged, the two ends of connecting rod 2 are hinged with handle 1, clamping head 4 respectively, in the upper end of support 3 are spacing inclined-planes 8, are provided with adjusting device 5 at the free end of clamping head 4, and adjusting device 5 comprises a bolt, two nuts; Clamping head 4 be provided with stopper slot 9 towards clamped thing 6 one sides, clamped thing 6 is angle steel in the present embodiment, stopper slot 9 is slightly larger than the thickness of angle steel.
Before welding, support 3 usefulness securing members are fixedlyed connected with welding platen 7, with weldment is that clamped thing 6 is placed on the welding platen 7, turning handle 1, handle 1 rotates clamping head 4 by connecting rod 2, the free end of clamping head 4 rotates towards clamped thing 6, referring to Fig. 2, clamped thing 6 snaps in stopper slot 9, when the bolt on the adjusting device 5 is close to clamped thing 6, quadric chain is in the dead-centre position, and promptly hinged center, connecting rod 2 two ends connecting line is parallel with the center line of handle 1 and vertical with the center line of clamping head 4; Be rotated further handle 1 again, the end that connecting rod 2 is linked to each other with clamping head 4 is close to the spacing inclined-plane 8 on the support 3, and this moment, quadric chain skipped over the dead-centre position, the thrust maximum, and because the position-limiting action on spacing inclined-plane 8, quadric chain is in highly stable state.
After welding is finished, backwards rotation handle 1, handle 1 drivening rod 2 backward rotation, quadric chain breaks away from the dead-centre position, and clamping head 4 unclamps clamped thing 6.
