Abstract
The utility model relates to a quick multifunctional bench vice which is characterized in that a sheath sleeve is arranged between a screw rod and a nut. The inner and outer of the thread sleeve are both provided with a trapezoidal thread. But an inner screw thread and the screw thread of the screw rod are alternately milled by 1/4 circumferential screw thread. The jaw frames of a fixed vice body and a movable vice body are provided with a semicylindrical jaw fixture. The utility model has the advantages of rapid clamping workpieces, complete clamping function, simple structure, reliable performance, less parts, low cost and suitable lot production.
Description
The utility model relates to a kind of instrument that is used for pincers worker, machined part clamping, specifically refers to the rotating disc type bench vice.
The conventional table vice is the work purpose that reaches the jaw closure or openness by screw mandrel and the relative rotation of nut.During for big different workpieces of size span or same workpiece different azimuth clamping, rotating cycle of screw rod reaches tens of circles sometimes.Especially to batch workpiece, rotary screw was both time-consuming repeatedly, required great effort again, and work efficiency is very low again.In addition, also because the jaw of old-fashioned bench vice is to adopt the cotton ginning plate that is fixed on fixed caliper and moving caliper jaw both sides to come holding workpiece.The function ratio of this jaw clamping workpiece is less, is not suitable for the workpiece of the irregular or surface smoothing of processing external form.Though the structure of bench vice improves to some extent in recent years, because its complex structure, parts are many, processing difficulties, and cost is high or because of its function singleness, and is little practical and fail to form and produce in enormous quantities, makes it to popularize.
It is both rapid that the purpose of this utility model provides a kind of clamping workpiece, the quick multifunctional bench vice that the clamping function is complete again, and it can accomplish simple in structure, parts are few, and are easy to process.
The purpose of this utility model is achieved in that on the basis of existing rotating disc type bench vice, spinning one is with externally threaded silk braid between screw mandrel and nut, part corresponding to 1/4 circumference about in this silk braid is a unthreaded hole, remaining part is a screw thread, and corresponding jaw frame (9) flexibly connects by connectors such as pin (11) or bolts with jaw anchor clamps (10).
Operation principle of the present utility model:
Referring to Fig. 2～Fig. 6, owing between screw mandrel and nut (6), be provided with silk braid (7), the inside and outside trapezoidal thread that all is shaped on of silk braid (7), but its internal thread and screw mandrel (2) screw thread has all respectively milled the screw thread of 1/4 circumference, so when operating grip (13) makes the threaded part of screw mandrel (2) change the unthreaded portion of silk braid (7) over to, push handle (13), screw mandrel (2) quick straight line in silk braid (7) is moved, and promptly screw mandrel (2) drives moving caliper (1) near fixed caliper (8).When jaw anchor clamps (10) during near workpiece, lead angle is little because screw mandrel (2) matches, import easily, and, on the external screw thread of silk braid (7), increase and import resistance, after making screw mandrel (2) screw thread at first import the internal thread of silk braid (7) and putting in place, silk braid (7) and screw mandrel (2) are done continuous worm drive together in nut (6), finely tune clamping and locking workpiece, at this moment screw mandrel (2) is located, after processing workpiece, same can deviate from screw mandrel (2) and put in place from silk braid (7) screw thread, drive silk braid (7) withdraws from from nut (6) screw thread and puts in place, and screw mandrel (2) is return fast, unloads workpiece.In a word, the utility model has utilized double-deck trapezoidal thread structure, the internal layer screw thread is play import and deviates from effect, and outer screw thread plays and advances and the locking effect.
Since jaw anchor clamps (10) can in the groove of jaw frame (9), slide from the screw thread that has also milled half about the screw mandrel corresponding to the part of 1/4 circumference vertically.The jaw frame of fixed caliper and moving caliper is made " U " type jaw frame respectively, and have 1～2 semi-circular recesses betwixt.Flexibly connecting 1～2 in the groove can be along the half-cylindrical jaw anchor clamps of groove slip, and the side of these half round post jaw anchor clamps has an arc eccentric through-hole, has the cross recess of " V " type on its working face.
The utlity model has following advantage:
1, screw mandrel and the silk braid owing to this device can radially break away from total travel or engagement, can realize axially moving freely of screw mandrel and silk braid during disengaging, screw mandrel drive silk braid carries out continuous worm drive with respect to nut during engagement, therefore this device can be finished the operation that clamps the locking workpiece in a second, it not only has clamping characteristics rapidly, but also has kept the advantage of conventional table vice reliable operation.
2, since this device have slidably freely and automatically adjusting angle in order to clamping the semicircle jaw anchor clamps of irregular special-shaped workpiece or surface smoothing workpiece, so it not only holding function is complete, but also dependable performance.
3, simple in structure, parts are few, and handling ease is with low cost, are fit to produce in batches.
4, use is easy to maintenance quick.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Referring to Fig. 1, moving caliper of the present utility model (1), back-up ring (12), handle (13), fixed caliper (8), positioning sleeve (4), rotating disc type base (3), nut (6), the topology layout of bolt parts such as (5) is the same with existing rotating disc type bench vice, it is characterized in that, spinning one has externally threaded silk braid (7) between screw mandrel (2) and nut (6), and being opposed to 1/4 circumferential section up and down in this silk braid (7) is unthreaded hole, and the part corresponding to 1/4 circumference about it is a screw thread, also milled the screw thread of half accordingly up and down vertically corresponding to the part of 1/4 circumference at screw mandrel (2), promptly screw mandrel (2) is a polished rod corresponding to the part of 1/4 circumference up and down.Remaining compartment is a screw thread, and the jaw frame of fixed caliper (8) and moving caliper (1) made " U " type jaw frame (9) respectively, and have 1～2 semi-circular recesses betwixt, being provided with 1～2 in groove can be along the half-cylindrical jaw anchor clamps (10) of groove slip, the side of these half round post jaw anchor clamps (10) has an arc eccentric through-hole, on the working face of these half round post jaw anchor clamps (10), have the cross recess of " V " type, the groove both sides of jaw frame (9) have the corresponding dowel hole of eccentric through-hole with jaw anchor clamps (10), as, when workpiece is pressed close to jaw anchor clamps (10), 4 jaw anchor clamps (10) adjusting angle voluntarily also slide on the workpiece of being close to the bench vice mouth very soon, make workpiece stressed all around, grip strength is even, add and also have " V " type cross recess on jaw anchor clamps (10) working face, so the workpiece of any irregular special-shaped workpiece or surface smoothing can both be clamped tightly.
