Abstract

The utility model relates to a quick-fastening and quick-loosening vice, which is composed of a fixed vice body 1, a movable vice body 2, a fixed rack 3, a left and a right guide rods 4, 6, a screw rod 5, a rocking handle 8 and a positioning locking mechanism 7 which traces the movable vice body 2. Because the movable vice body 2 can move quickly along the left guide rod 4, the right guide rod 6 and the screw rod 5 between the fixed rack 3 and the fixed vice body 1 when the lock is opened, the utility model accelerates the speed of assembling and disassembling workpieces and obviously improves efficiency; in addition, materials are saved, weight is lightened, and the varying range of the vice mouth size is widened.

Description

Speedy tightening/loosening bench clamp

The utility model relates to a kind of improvement of bench vice, specifically, but is a kind of bench vice of push-and-pull moved jaw.

As everyone knows, bench vice is that people are used for clamping the instrument that workpiece is processed, and its application scenario is very extensive.Though work posts such as pincers worker, plumber, mould, casting and carpenter, or the maintenance work in the daily life etc. all be unable to do without it, the width of the workpiece of being entreated by several millimeters to the hundreds of millimeter, range spans is very big.But the present bench vice that uses, pincers clamping of workpieces or unclamp workpiece and all lean on the rocking-turn screw mandrel to come the distance of mobile moving caliper and fixed caliper, precession length by length, speed is very slow, particularly run into the very big occasion of its different azimuth thickness variation scope of processing work, for example change to 300 millimeters from 5 millimeters, influence the raising of operating efficiency just fairly obviously.Simultaneously, because present commercially available bench vice is to be made of fixed caliper, moving caliper, mounting seat and screw mandrel and rocking handle, moving caliper moves along the guide rail on the base.Therefore, have also that volume is big, Heavy Weight, the jaw excursion is restricted and owing to jaw must exceed some trouble that workpiece that the steady job table top causes adds man-hour significantly.

The purpose of this utility model provides a kind of bench vice of workpiece loading and unloading apace.

Technical solution of the present utility model is: 1. be provided with and the meshing locking mechanism opened of screw mandrel; 2. save the mounting seat of existing bench vice, the guide rail on the original base is made into to being positioned at the guide post of screw mandrel left and right sides.Thus, the utility model comprises fixed caliper, moving caliper, screw mandrel, guide post, fixed mount, rocking handle and position and lock mechanism.Guide post is positioned at screw mandrel both sides and parallel to each other, by fixed caliper and fixed mount fixed guide pole and support screw.Moving caliper is between fixed mount and fixed caliper, and mechanism is in opening when position and lock, and moving caliper can be along guide post and screw mandrel fast moving-be straight line advance and retreat rather than spiral advance and retreat.The synchronous tracking lock of position and lock mechanism and moving caliper in the time will vising workpiece, makes the location lock meshing with screw mandrel, and workpiece is just fastened motionless.When unloading workpiece, as long as position and lock mechanism has been opened.Moving caliper moves, and position and lock mechanism is also following the tracks of the locking of waiting for screw mandrel, uses very convenient.

The utility model has the advantages that: but 1. fast moving moving caliper is convenient to the loading and unloading to workpiece, compares with existing bench vice, can increase work efficiency 5～10 times; 2. material is saved in weight saving; 3. the jaw movable range is big, can entreat the workpiece that is as thin as several millimeters thick to 300 millimeter.

The utility model is implemented by the following drawings.

Fig. 1 is a combination general picture schematic diagram of the present utility model.

Fig. 2 is a structural representation of the present utility model.

According to Fig. 1 and Fig. 2, provide one of the utility model embodiment and being set forth preferably, ins and outs of the present utility model further are provided.Among Fig. 1, the utility model comprises fixed caliper 1, moving caliper 2, fixed mount 3, left guide post 4, screw mandrel 5, right guide post 6, position and lock mechanism 7 and rocking handle 8, also has installing hole 9 on the moving caliper 2.Left and right guide post 4,6 and screw mandrel 5 are parallel and be positioned at the left and right sides of screw mandrel 5.Connect with cooperating for 5 one-tenth with fixed mount 3 fixing left and right guide posts 4,6 by fixed caliper 1 with screw mandrel.Moving caliper 2 and is inserted in 5 one-tenth loose fits of left and right sides guide post 4,6 and screw mandrel between fixed caliper 1 and fixed mount 3.Position and lock mechanism 7 follows the tracks of synchronously with moving caliper 2 and connects.Mobile bench vice 2 is opened position and lock mechanism 7 when workpiece loading and unloading, after tightening up workpiece, position and lock mechanism 7 is locked.Rocking handle 8 passes screw mandrel 5 heads.From Fig. 2 as seen, an end of screw mandrel 5 passes fixed mount 3 backs and inserts pin 19 to fix it.Position and lock mechanism 7 comprises kayser 12, lock frame 11, the bar 10 of unblanking, unlocking handle 13.Unlocking handle 13 is connect by unlocking handle return spring 15 with fixed caliper 1, and the inner ring and the unlocking handle 13 of this spring 15 tightly connect, and its outmost turns contacts with fixed caliper 1.Lock frame 11 is fixed on the moving caliper 2.There is the line tooth 18 mutually meshing with screw mandrel 5 lower end of kayser 12, and the medium pore 17 of lock frame 11 is passed in the upper end, putting in the right position has the unblank fluting 16 of bar 10 of the supporting of putting, and an end of the bar 10 of unblanking and unlocking handle 13 are connect by pinning 14, and it is lateral opening and insert and slot 19 to pass the both sides of lock frame 11 afterwards again.Pulling handle 13 can make kayser 12 rise and discharge locking to screw mandrel 5.

Claims (3)

1, a kind of quick tense-lax bench vice, comprise that fixed caliper 1, an end pass and cooperate the screw mandrel 5 that connects with fixed caliper 1, be inserted in the moving caliper 2 of screw mandrel 5, cooperate the fixed mount 3 of connection with screw mandrel 5 other ends and stretch out the rocking handle 8 that the outboard end of fixed caliper 1 connects mutually, it is characterized in that with screw mandrel 5:

A. have tightly connect, pass with fixed caliper 1 and 2 adaptive with moving caliper, again with the fixed mount 3 tight left and right sides guide posts 4,6 that connect, they lay respectively at the left and right sides of screw mandrel 5 and parallel with screw mandrel 5,
