Abstract
The utility model relates to a machine tool accessory which comprises a chassis, a tong body, a fixed jaw and a movable jaw controlled by a handle, wherein, the back end of the bottom surface of the movable jaw is provided with two symmetrical ring slots; circular rings, the material hardness of which is lower than that of the tong body, are inlaid in the ring slots; the cross sections of the ring bodies of the circular rings form a circular shape, and the diameters are larger than the depth of the ring slots. A machine flat tong using the technical proposal has the advantages that the ratio of precision is increased as compared with the existing machine flat tong, and the service life of the flat tong is prolonged.
Description
The utility model relates to a kind of machine tool accessories.
Machine vise is a kind of machine tool accessories that is widely used in milling machine, planer, grinding machine, drilling machine etc.Flat-nose pliers is to the clamping of workpiece and loosen, and is by shaking handle, make the screw mandrel rotation, thereby the push-and-pull moving jaw moving back and forth.At present, the machine vise caliper and the moving jaw that generally use of the public mostly is ironcasting.In use, moving jaw is reciprocating on the caliper guide pass, after long-time the use, can cause the wearing and tearing and the scuffing of caliper guide rail surface or moving jaw bottom surface; In addition, the workpiece of different external forms can produce warpage or arch upwards when clamping, thereby it is unstable to cause workpiece to clamp.Owing to have above-mentioned defective, will inevitably cause the flat-nose pliers service precision to reduce.
The purpose of this utility model provides and a kind ofly can effectively overcome the deficiencies in the prior art part and improve the machine vise of its service precision greatly.
The high accuracy machine vise that the utility model provides, comprise chassis, caliper, regular jaw and by the moving jaw of stick control, be provided with the cannelure of two symmetries in the rear end, bottom surface of moving jaw, inlaid material hardness is lower than the annulus of caliper hardness in the groove, annulus ring body cross section is circular, and its diameter is greater than the degree of depth of cannelure.Like this, when the moving jaw that is provided with annulus was installed on the caliper, just by two annulus actual contact caliper guide rail surface, raised slightly the rear end, bottom surface of moving jaw.Because the hardness of annulus is lower than the hardness of caliper, thereby can reduce the wearing and tearing of caliper; After raise the jaw rear end, can overcome workpiece issuable warpage or go up doming effect when clamped, make it stable more, reliable.
Owing to adopted technique scheme, service precision of the present utility model improves greatly than existing machine vise, and has improved the service life of flat-nose pliers.
(embodiment) is further described the utility model below in conjunction with accompanying drawing.
Fig. 1 is the front schematic view of the utility model user mode.
Fig. 2 is the bottom surface structural representation of moving jaw.
Fig. 3 is the B-B view of Fig. 2.
Fig. 4 is the circular ring structure schematic diagram.
As shown in the figure, the utility model is made up of chassis 1, caliper 2, jaw 3,7 and operating grip 8, the contact-making surface of jaw and workpiece 5 is provided with jaw pad 4,6, be provided with the cannelure 9 of two symmetries in the rear end, bottom surface of moving jaw 7, groove depth h is 1.4 millimeters, inlay annulus 10 in the groove, the ring body cross section is circular, and its diameter d is 1.5 millimeters.Like this, annulus will protrude 0.1 millimeter of moving jaw bottom surface.The material of annulus is a nylon, and its wearability is stronger, but its hardness is still well below caliper hardness.So, when moving jaw 7 moves back and forth, be actually mobile on the guide rail of caliper on caliper, thereby significantly reduced the wearing and tearing of caliper, the service life of having improved flat-nose pliers by the nylon annulus.After the wearing and tearing of nylon annulus, can replace at any time, very convenient.In addition, because inlaying the rear end of the moving jaw 7 behind the annulus raises slightly, when shaking handle 8 clamping work pieces, can produce a downward component Fy to workpiece, (referring to Fig. 1), so just can overcome workpiece when clamped issuable warpage or on doming effect, thereby stable when making workpiece clamped, reliable.
