Abstract
The utility model relates to machine tool accessories, in particular to flat pliers used for a machine tool. The shape of the flat pliers is similar to that of the flat pliers used for the old machine, the force direction is changed and the problems of workpiece upwarping in clamping workpieces of the flat pliers and deformation or breakage of a pliers body of the common flat pliers under force are solved by changing the shapes of a screw rod and a screw nut and the connection method of the screw rod and the screw nut with a fixed pliers body and a movable pliers body. The precision flat pliers have the advantages of simple structure, large opening distance, convenient operation and maintenance and low manufacturing and maintenance costs.
Description
Technical field
The utility model relates to a kind of machine tool accessories, the precision flatnosed pliers that particularly a kind of lathe uses.
Background technology
Existing common flat-nose pliers is when clamping parts, because the caliper structure problem, part upwarps when causing clamping part, has destroyed the machining accuracy of part.If adopt "painted-face" character in opera to knock, both destroyed the positioning accuracy of part, reduced production efficiency again, the precision influence to lathe itself when percussion power is excessive is also bigger.Simultaneously, because the flat-nose pliers leading screw adopts the mode clamping work pieces on top, cause flat-nose pliers caliper when stressed to occur bending and deformation and even fracture.
Summary of the invention
The purpose of this utility model is by changing leading screw, the profile of screw and the juncture of leading screw, screw and fixed caliper and moving caliper, change moving caliper and be subjected to force direction, the problem that workpiece upwarps when having solved the flat-nose pliers clamping workpiece, and the problem that has solved the stressed forceps major body deformability of common flat-nose pliers or fractureed by the connected mode that changes leading screw and fixed caliper.The utility model is simple in structure, extended distance is big, operation and easy to maintenance, cheap for manufacturing cost.
The purpose of this utility model is realized by following technical scheme: a kind of anti-precision flatnosed pliers that upwarps, it is included in regular jaw 2, pad 8, leading screw 9 is installed on the fixed caliper 1, leading screw 9 cooperates with screw 6 and contacts with roller 5 formation lines, when female 6 rectilinear motions of leading screw 9 rotating band movable wires, move by roller 5 drive moving calipers 4 and moving jaw 3, thereby realization is to the clamping of part.10 pairs of leading screws 9 of gripper shoe play the supplemental support effect, and prevent leading screw 9 play when jaw opens by back-up ring 11 and jackscrew 12.Backplate 7 adopts screw to be fixed in caliper with gripper shoe 10.
The beneficial effects of the utility model are, can prevent in the parts fixation process that part from upwarping and the caliper distortion, have improved the speed and the precision of parts fixation, and simple in structure, make easy to maintenance, with low cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the anti-general assembly drawing that sticks up precision flatnosed pliers embodiment.
Fig. 2 is the anti-A-A cutaway view that sticks up precision flatnosed pliers embodiment.
1. calipers among the figure, 2. regular jaw, 3. moving jaw, 4. moving caliper, 5. roller, 6. screw, 7. backplate, 8. packing ring, 9. leading screw, 10. gripper shoe, 11. back-up rings, 12. jackscrews.
The specific embodiment
Utilize drawings and Examples that the utility model is further described below.
With reference to Fig. 1, present embodiment is the anti-precision flatnosed pliers that upwarps, its external form is similar to old-fashioned machine vise, by changing the profile and the leading screw 9 of screw 6, the juncture of screw 6 and fixed caliper 1 and moving caliper 4, changed the force direction that is subjected to of moving caliper 4, thereby having solved that flat-nose pliers workpiece when clamping workpiece upwarps and stressed forceps major body deformability of common flat-nose pliers or the problem that fractures. it is included in regular jaw 2 is installed on the fixed caliper 1, pad 8, leading screw 9, leading screw 9 cooperates with screw 6 and contacts with roller 5 formation lines. when female 6 rectilinear motions of leading screw 9 rotating band movable wires, move by roller 5 drive moving calipers 4 and moving jaw 3, realize clamping to part. screw 6 is 45 ° of inclined-planes with the contact-making surface of roller 5, when promoting moving caliper 4 and moving jaw 2 clamping work pieces forward, produce downward pressure, moving caliper 4 and moving jaw 3 are pressed on the guide pass of fixed caliper, prevented that moving caliper from upwarping, guaranteed the clamping force and the clamping precision of part.
The leading screw 9 of present embodiment is that the power of being born is pulling force at clamping workpiece, its pulling force that bears equates with the clamping force of workpiece and the pressure sum that is applied on the moving caliper 4, and the pressure of 6 pairs of fixed calipers 1 of pressure that fixed caliper 1 bears and screw equates, fixed caliper 1 only bears the pulling force that leading screw 9 is produced at the end that pad 8 is installed, therefore, when having guaranteed part clamping, positioning stablity, avoided the distortion of fixed caliper 1, thereby further improved the precision of flat-nose pliers.9 of 10 pairs of leading screws of gripper shoe play the supplemental support effect, and prevent leading screw 9 play when jaw opens by back-up ring 11 and jackscrew 12.Backplate 7 adopts screw to be fixed in caliper with gripper shoe 10.
Claims (2)
1. prevent upwarping precision flatnosed pliers for one kind, it is included in regular jaw (2) is installed on the fixed caliper (1), pad (8), leading screw (9), leading screw (9) cooperates with screw (6) and contacts with roller (5) formation line, when leading screw (9) rotating band movable wire mother (6) rectilinear motion, move by roller (5) drive moving caliper (4) and moving jaw (3), thereby realize clamping to part, gripper shoe (10) plays the supplemental support effect to leading screw (9), and preventing leading screw (9) play when jaw opens by back-up ring (11) and jackscrew (12), backplate (7) adopts screw to be fixed in caliper with gripper shoe (10).
