Technical field
The utility model relates to the clamping of a kind of workpiece or cutter, and supporting, positioner, is specifically related to a kind of flat-nose pliers Bidirectional clamping apparatus.
Background technology
Flat-nose pliers has another name called machine vice, is a kind of universal fixturing, is usually used in installing miniature workpiece, and it is the random annex of milling machine, drilling machine, is fixed on platen, is used for holding workpiece to carry out machining.Generally include screw rod, moving jaw, clamp block and square nut, moving jaw is connected by pin with square nut, and screw rod is threaded with square nut, uses spanner rotating screw bolt, drives moving jaw to move by screw rod, formed to the clamping of workpiece with unclamp.
For existing flat-nose pliers, moving jaw and square nut by the dead locate mode of pin, due to pin be moving jaw, square nut is connected, so its interchangeability is poor.So when adopting existing flat-nose pliers clamping work pieces, in order to clamp the workpiece of difformity, size, then different flat-nose pliers must be changed.
Utility model content
For the defect that above-mentioned prior art exists, the purpose of this utility model is to provide one to be convenient for changing jaw seat, is convenient to the flat-nose pliers Bidirectional clamping apparatus of workpiece clamping sizes, shape.
For achieving the above object, the technical solution of the utility model is: flat-nose pliers Bidirectional clamping apparatus, comprise clamp block, screw rod, jaw seat and moving jaw, described clamp block is provided with groove, it is equal that described screw rod bilateral symmetry is provided with pitch, the screw thread that rotation direction is contrary, described moving jaw is connected with jaw seat, wherein, clamp block in the middle part of described screw rod is provided with the location structure of screw rod, in addition, have additional the slide be threaded with screw rod both sides respectively, screw rod and slide are positioned at groove, described slide is provided with positioning boss and screwed hole, described jaw seat is provided with the positioning runner coordinating positioning boss, and the installing hole of mate with threaded holes, jaw seat and slide adopt screw to be connected by installing hole and screwed hole.
When adopting technique scheme, workpiece to be held is placed between two moving jaws, because screw rod bilateral symmetry is provided with the screw thread that pitch is equal, rotation direction is contrary, and the slide that screw rod is threaded with screw rod both sides respectively, rotating screw bolt, makes two slide relative movements, because jaw seat is connected with slide, and moving jaw is connected with jaw seat, so moving jaw also relative motion thereupon, thus by Workpiece clamping; Rotate backward screw rod, the slide of screw rod both sides then moves in opposite directions, and equally, two moving jaws be connected with both sides slide also move toward one another thereupon, unclamps workpiece.In the utility model, slide is provided with positioning boss and screwed hole, so the jaw seat that only need be connected with slide is provided with the positioning runner coordinating positioning boss, and the installing hole of mate with threaded holes, by the adjustment position of positioning boss in positioning runner, installing hole and screwed hole are aligned.Then jaw seat and slide adopt screw to be connected by installing hole and screwed hole.Under prerequisite like this with regard to energy same clamping device, by changing different jaw seats and positioning wrench jaw, clamp the workpiece of different size, shape.
Further, for diameter is less than the cylinder of both sides in the middle of described screw rod, described location structure is the positioning seat be fixed in the middle part of clamp block, and described positioning seat is provided with the through hole coordinating cylinder in the middle part of screw rod, and positioning seat both sides offset with the end face at cylinder two ends respectively.In the process of rotating screw bolt, positioning seat both sides offset with the end face at cylinder two ends respectively, so can prevent screw rod movement in the axial direction.
Further, described cylinder is arranged with bearing, and bearing arrangement is in through hole.During rotating screw bolt, avoid cylinder in the middle of screw rod directly and the through hole friction of positioning seat, rotating screw bolt is more laborsaving.
Further, for diameter is less than the cylinder of both sides in the middle of described screw rod, described location structure is for being located at cylinder two ends, and the limiting plate offseted with cylinder end face respectively.The limiting plate at such cylinder two ends can limit screw rod movement vertically.
Further, described slide is provided with two positioning boss and two screwed holes, and two positioning boss, two screwed holes are symmetrical about screw axis respectively.In holding workpiece process, moving jaw is stressed comparatively large, and therefore, require that slide and jaw seat are connected firmly, slide arranges two positioning boss and just jaw seat stably can be connected with slide with two screwed holes.
