Abstract
The invention discloses a clamping device, in particular to an interior clamping device. The interior clamping device comprises a base and a support seat, wherein a boss is arranged in the middle of the base, and the support seat is sheathed on the boss; the upper surface of the support seat is a circular workbench; a centering cone is arranged between the support seat and the boss and provided with a centering cone head; and a through hole is formed in the base, a guide rod is arranged in the through hole, one end of the guide rod, which is near the centering cone head, is hinged with one end of a clamping jaw, the other end of the clamping jaw is a clamping end which is matched with the workbench to clamp a workpiece, and the middle part of the clamping jaw is hinged with the upper end of the boss. The interior clamping device can be used for fixing the workpiece with a cylindrical inner cavity.
Description
Technical field
The invention belongs to the technical field of anchor clamps, relate in particular to a kind of inner clamping device.
Background technology
Clamping device is widely used for manufacturing, as to punching press, riveted joint, the welding of workpiece, paste or solidify etc. and usually need the position relationship that keeps correct in the process, clamping device has various reference surfaces or point, workpiece can accurately be located, so clamping device is considered to requisite parts in the processing industry.
Existing Internal jigging is normally by a pair of claw, the inner chamber of holding workpiece fixes processing object, make it to occupy correct position, to accept construction or to detect, but fixing inner chamber by a pair of claw holding workpiece inside is columniform workpiece, and its limitation is: occur easily skidding when fixedly inner chamber is columniform workpiece 1.; 2. when externally surface smoothness has the workpiece of special requirement to be fixed, can damage outer surface of workpiece, affect the workpiece crudy.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of inner clamping device, and fixedly inner chamber is the workpiece that columniform workpiece and external surface smoothness have specific (special) requirements.
The technical solution adopted in the present invention is: include pedestal and supporting seat, be provided with boss in the middle of the described pedestal, supporting seat is enclosed within on the boss, and the supporting seat upper surface is circular workbench, is provided with centering cone between supporting seat and the boss, centering cone has centering cone head, the inside of pedestal is provided with through hole, is provided with guide rod in the through hole, and an end of the close centering cone head of guide rod and an end of jaw are hinged, the other end of jaw is the bare terminal end that cooperates holding workpiece with workbench, and the jaw middle part is hinged with the boss upper end.
Compared with prior art, the invention has the advantages that: move upward by guide rod, drive jaw and put outward, block workpiece, because workbench is circular, coincide so be that columniform workpiece is easier to inner chamber; Owing to be to be fixed by holding inside workpiece, so workpiece is fixed Shi Buhui to the outer surface of workpiece injury.
Further, described centering cone has three, and three centering cones are at grade 120 ° and are evenly distributed on around the boss.This kind structure can accurately be located cylindrical work, and centering cone cooperates supporting seat and the common fixation workpiece of jaw, makes fixing more firm.
Further, described centering cone is provided with stage clip between the bottom of centering cone and the pedestal, can so that centering cone after workpiece withdraws from, under the effect of stage clip, automatically reset.
Further, described guide rod is provided with feather key, and boss inside is provided with chute, and feather key embeds chute, in the time of can moving up and down to guide rod, can position guide rod, rotation when preventing the guide rod motion.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, the inside clamping device of present embodiment includes pedestal 1 and supporting seat 2, be provided with boss in the middle of the described pedestal 1, supporting seat 2 is enclosed within on the boss, and supporting seat 2 bottoms are by bolt 3 and pedestal 1 bottom fixed-link, and supporting seat 2 upper surfaces are circular workbench.
Be provided with centering cone 6 between supporting seat 2 and the boss, described centering cone has three, and three centering cones are at grade 120 ° and are evenly distributed on around the boss, and centering cone 6 has centering cone head.
The inside of pedestal 1 is provided with through hole, be provided with guide rod 4 in the through hole, guide rod 4 is provided with feather key 8, hole wall at pedestal 1 through hole is provided with chute, feather key 8 embeds chute, and an end of guide rod 4 close centering cone heads and an end of jaw 5 are hinged, and the other end of jaw 5 is the bare terminal end that cooperates holding workpiece 9 with workbench, jaw 5 middle parts and boss upper end is hinged, is provided with stage clip 7 between the bottom of described centering cone 6 and pedestal 1.
During use, guide rod 4 is moved upward, drive the jaw 5 outer pendulum that are connected on the guide rod 4, block workpiece 9.Centering cone 6 has three, and is at grade 120 ° and is evenly distributed on around the boss, can be that columniform workpiece 9 is accurately located to inner chamber, and centering cone 6 cooperates supporting seat 2 and jaws 5, so that the workpiece 9 that will fix is more firm.Be provided with stage clip 7 between the bottom of centering cone 6 and the pedestal 1, can be so that centering cone 6 after workpiece 9 withdraws from, automatically reset under the effect of stage clip 7, the feather key 8 on the guide rod 4 positions in the time of can sliding to guide rod 4, prevents from spinning when guide rod 4 from moving up and down.
