Abstract
The utility model provides a fast cam self-locking table vice, which uses the cam mechanism to amplify the external force to obtain the proper clamp force which can push the clamping vice body to hold the workpiece firmly. The cam can be self-locked when the external force is canceled. The utility model is convenient to operate and simple to control and grasp the clamping force, which can ensure the certain easily damaged workpiece not be damaged. The cam rotation angle is small to clamp the workpiece firmly, which only needs a rotation of 0-180 degrees. The utility model can save work time and improve the work efficiency.
Description
Technical field
The utility model relates to a kind of clamping device class, and more particularly, it relates to a kind of bench vice that has energy self-locking cam control gear.
Background technology
At present, the pincers worker section in each workshop of machine works, mostly the clamping device that extensively adopts in repair shop, industrial and mining enterprises, architectural hardware and other industry is traditional guide screw matrix bench vice.This class bench vice is made of pincers seat, nut, screw rod, moving caliper etc.Come the position of moved jaw stroke by rotating screw bolt, its roll adjustment speed is slower, troublesome poeration, and efficient is lower.Though there is a lot of patented invention to adopt methods such as improving nut structure, screw thread trend now, improve clamping speed to workpiece, could clamping work pieces because of still wanting rotary screw several weeks, its folder speed is still had a greatly reduced quality.Up till now for this reason, it is easy to control not see a kind of clamping force, and fast save time, easy to operate bench vice.
Summary of the invention
The quick cam self-locking bench vice that provides a kind of clamping force easy to control, easy to operate is provided the purpose of this utility model.
Quick cam self-locking bench vice of the present utility model comprises loose caliper body 1, return spring 2 and 7, grips caliper 3, clamps seat 4, cam 5, screw 6 and 8, compression spring 9, positioning ball 10, spur rack 11, key 12, stop pin 13.Pincers seat 4 in the vertical directions of described bench vice are provided with two square holes, the loose caliper body 1 that is fastened with spur rack 11 is set in the following square hole, spur rack 11 and 4 of pincers seats are provided with the positioner of compression spring 9 and positioning ball 10 compositions, be provided with in the upper aperture return spring 2 is housed grip caliper 3, grip the cam 5 that caliper 3 back are equipped with the band handle, cam 5 bottom surfaces of band handle are milled with groove 14, groove 14 is to be the center of circle with the cam pivot, dark both sides, middle part smoothly shoal gradually, and carry out the transition to the arc-shaped slot of cam face, between cam 5 and the loose caliper body 1 stop pin 13 is installed, stop pin 13 is "T"-shaped cylinder lock, and its top is a spherical crown, there is tooth the cylinder bottom surface, cylindrical side is equipped with key 12, stop pin 13 is cooperated with pincers seat 4 prevent its rotation, and stop pin 13 outsides are with return spring 7.Spur rack 11, return spring 7, stop pin 13 are formed locking device.
The beneficial effects of the utility model are: (1) is easy to operate, and clamping force is easy to control, thereby has guaranteed that the bad workpiece of some easy folder is unlikely to be pressed from both sides bad.(2) just can clamp or unclamp workpiece because of cam only needs the rotation of 0～180 degree,, improve work efficiency so saved the time.

The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
In Fig. 1, quick cam self-locking bench vice of the present utility model mainly by loose caliper body 1, return spring 2 and 7, grip caliper 3, pincers seat 4, cam 5, screw 6 and 8, compression spring 9, positioning ball 10, spur rack 11, key 12, straight stop pin 13 and form.Described pincers seat 4 in the vertical directions are provided with two square holes, the loose caliper body 1 that is fastened with spur rack 11 is set in the following square hole, spur rack 11 and 4 of pincers seats are provided with the positioner of compression spring 9 and positioning ball 10 compositions, positioning ball 10 and spur rack 11 cooperate, after moving loose caliper body 1 folder workpiece, can make spur rack 11 corresponding with the tooth of stop pin 13, and mutually interlock and with loose caliper body 1 locking; Be provided with in the upper aperture return spring 2 is housed grip caliper 3, grip the cam 5 that caliper 3 back are equipped with the band handle, cam 5 bottom surfaces are milled with groove 14, in conjunction with Fig. 2, groove 14 is to be the center of circle with the cam pivot, and dark both sides, middle part smoothly shoal gradually, and carry out the transition to the arc-shaped slot on cam 5 surfaces, the design of its groove arc length and change in depth should be satisfied before rotating cam 5 clamping work pieces and to promote stop pin 13 earlier and move down loose caliper body 1 locking, after promote to grip caliper 3 clamping work pieces again.Between cam 5 and the loose caliper body 1 stop pin 13 is installed, in conjunction with Fig. 3, stop pin 13 is "T"-shaped cylinder lock, its top is a spherical crown, and there is tooth the cylinder bottom surface, and cylindrical side is equipped with key 12, stop pin 13 is cooperated with pincers seat 4 prevent its rotation, stop pin 13 outsides are with return spring 7.
The design of the eccentric throw of cam and the tooth pitch of spur rack will determine the multiplication factor of external force, can be selected in millimeter level value, and the more little external force multiplication factor of eccentric throw just improve greatly more.The design of groove arc length and change in depth should design with reference to other parameters such as eccentric throw and spur racks, and will satisfy before rotating cam 5 clamping work pieces and to promote stop pin 13 earlier and move down loose caliper body 1 locking, after promote to grip caliper 3 clamping work pieces again.
Directly move loose caliper body 1 during clamping workpiece and block workpiece, rotating cam 5 again, and cam 5 promotes stop pin 13 and moves, block loose caliper body 1, loose caliper body 1 position is fixed, then along with being rotated further of cam 5, promote again to grip caliper 3 tightly clamp workpiece.Cam 5 self-lockings after external force is cancelled, and grip caliper 3 can not after move, this moment workpiece firmly clamped.
