Abstract
The invention discloses a clamping device with a wedge block to solve the problems of complex structure and unstable clamping of an existing clamping device. The clamping device comprises a cylinder and a clamping jaw. The clamping device is characterized by further comprising the slidable wedge block, a first roller and a transmission rod, the slidable wedge block is arranged at the bottom of a piston rod of the cylinder, the side of the slidable wedge block is provided with an inclined section, the inclined section is abutted to the first roller, the first roller is arranged at one end of the transmission rod, the other end of the transmission rod is connected with the lower portion of the clamping jaw, the middle of the clamping jaw is hinged, the upper portion of the clamping jaw is provided with a clamping end, a clamping table is arranged in the side of the cylinder and matched with the clamping end to clamp workpieces, and the slidable wedge block, the first roller and the transmission rod are arranged in the guide groove. The clamping device is simple in structure and stable to operate.
Description
Technical field
The present invention relates to Machining Technology, be specifically related to a kind of clamping device with voussoir.
Background technology
Clamping device is widely used for manufacturing, as to the punching press of workpiece, riveted joint, welding, paste or solidify etc. and in process, usually need the position relationship that keeps correct, clamping device has various reference surfaces or point, workpiece can accurately be located, so clamping device is considered to requisite parts in processing industry.
Clamping device generally adopts cylinder or oil cylinder as power, but existing clamping device power transmission arrangment is more complicated, generally will just can make dynamic action in jaw through multi-level transmission, just can clamp or unclamp action, causes holding action unstable.
Summary of the invention
The invention provides a kind of clamping device with voussoir, to solve complex structure that existing clamping device exists, to clamp unsettled problem.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
Clamping device with voussoir, comprise cylinder and jaw, also comprise sliding wedge, the first roller and drive link, sliding wedge is arranged on the piston rod bottom of cylinder, the side direction of sliding wedge is tilting section, described tilting section and the first roller offset, the first roller is arranged on one end of drive link, the other end of drive link is connected with the bottom of jaw, the middle part of jaw is hinged, the top of jaw is bare terminal end, and the side direction of cylinder is provided with the grain-clamping table that coordinates holding workpiece with described bare terminal end, and sliding wedge, the first roller and drive link are all arranged in guide groove.
This clamping device promotes sliding wedge by cylinder and moves up and down, and by roller and drive link, makes in jaw bottom pendulum or pendulum outward, because the middle part of jaw is hinged, therefore, and clamping work pieces during pendulum in the bare terminal end on jaw top, bare terminal end unclamps workpiece outward while putting.
Than existing clamping device, this device is by sliding wedge, roller and drive link transferring power, and simple in structure, voussoir inclined plane coordinates transferring power with roller, can guarantee to transmit the stability of action.
Further, described voussoir dorsad a side of tilting section be provided with the second roller, the second roller is arranged in guide groove.The second roller is set, can reduces because voussoir bears the friction that clamping force produces.
Further, on described tilting section surface, be provided with one deck cushion course.Impact when cushion course can reduce transmission of power, makes to transmit more stable.
Accompanying drawing explanation
Fig. 1 is that the present invention is with the structural representation of the clamping device embodiment of voussoir.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
The clamping device with voussoir as shown in Figure 1, comprise cylinder 1, jaw 7, grain-clamping table 8, sliding wedge 2, the first roller 3, the second roller 4 and drive link 6, sliding wedge is arranged on the piston rod bottom of cylinder, the side direction of sliding wedge is tilting section, on described tilting section surface, be provided with one deck cushion course 5, described tilting section and the first roller offset, the first roller is arranged on one end of drive link, the other end of drive link is connected with the bottom of jaw, the middle part of jaw is hinged, the top of jaw is bare terminal end, the side direction of cylinder is provided with the grain-clamping table that coordinates holding workpiece with described bare terminal end, sliding wedge, the first roller and drive link are all arranged in guide groove, described voussoir dorsad a side of tilting section be provided with the second roller, the second roller is arranged in guide groove.
This clamping device promotes sliding wedge by cylinder and moves up and down, and by roller and drive link, makes in jaw bottom pendulum or pendulum outward, because the middle part of jaw is hinged, therefore, and clamping work pieces during pendulum in the bare terminal end on jaw top, bare terminal end unclamps workpiece outward while putting.
