Abstract
The utility model provides a machine vice for high-speed clamping workpiece, which is composed of a plurality of parts, such as a fixed vice body, a movable vice body, a jaw iron, a screw, a guiding rod with teeth, guiding nuts, etc. The teeth on the side face of the guiding nuts can be connected, combined, or separated with the teeth on the top face of the guiding rod. When the teeth on the side face of the guiding nuts are connected and combined with the teeth on the top face of the guiding rod, the use of the vice is the same with a general machine vice. When the teeth on the side face of the guiding nuts are separated with the teeth on the top face of the guiding rod, the movable vice body can slide freely on the guiding rod. The dimension of the opening of the jaw can be adjusted by pushing and pulling the movable vice body, but not by rotating the wrench. So the time can be saved and the high-speed clamping can be realized.
Description
The utility model relates to a kind of improved machine vice, the machine vice of the quick clamping work pieces of particularly a kind of energy.
The quick clamping machine vice that uses both at home and abroad is divided into following three kinds substantially at present: the one, utilize the left and right screw mandrel that revolves, and drive left and right jaw respectively, reach quick clamping, loosen; The 2nd, utilize eccentric stiffener; The 3rd, utilize off-centre or screw mandrel to do clamping, uncoupling gear, utilize the moving caliper stepping to slide, locate coarse adjustment then as openings of sizes, the clamping force size all is subjected to the restriction of eccentric throw, adaptability to workpiece processing is very narrow, the third then needs twice adjustment, only is suitable for having the workpiece processing of certain batch.Task of the present utility model is that a kind of improved machine vice will be provided.This device did not need rotating spanner before clamping work pieces, only need push away, draw moving caliper just can regulate the size of jaw opening size, saved time, and reached the purpose of quick clamping work pieces.
Task of the present utility model is to realize (with reference to accompanying drawing) like this:
On fixed caliper (1), be fixed with two toothed guide posts in side (3), moving caliper (2) is linked together with screw mandrel (4), can slide before and after guide post (3) is gone up.There is serrated teeth guiding nut (5) two sides above the screw mandrel (4), can with the indented joint above the guide post (3).Go up boring at guiding nut (5) and communicate with screw, the nylon block of packing in the hole (6), spring (7) are tightened with screw (8).The elastic force of spring (7) is pressed on the screw mandrel (4) nylon block (6), increases the friction of guiding nut (5) and screw mandrel (4).
When the tooth of guiding nut (5) side during not with the indented joint of guide post (3), with hand push, draw moving caliper (2), it before and after going up, guide post (3) is slided, regulate the size of jaw opening size.When reaching dimensional requirement, clockwise rotate screw mandrel (4), make screw mandrel (4) drive guiding nut (5) and clockwise rotate, the side tooth of guiding nut (5) begins the side indented joint with guide post (3).Along with the rotation of screw mandrel (4), when the side tooth of guiding nut (5) all engages with the side tooth of guide post (3), guiding nut (5) will no longer rotate, at this moment, produce relative motion between screw mandrel (4) and the guiding nut (5), the caliper (2) that promotes to live moves, and workpiece is clamped.
When rotating counterclockwise screw mandrel (4), relative motion takes place earlier with guiding nut (5) in screw mandrel (4), and the clamping force between jaw and workpiece is disappeared, and is also no longer stressed between guiding nut (5) and the guide post (3).Under the effect of spring (7), guiding nut (5) rotates together in company with screw mandrel (4), all breaks away from guide post (3), and moving caliper (2) can be free to slide on guide post again.
When the tooth pitch of guide post (3), guiding nut (5) soldered tooth was identical with screw mandrel pitch, screw mandrel (4) rotated within the week and just workpiece can be clamped.

Claims (1)
- A kind of machine vice of quick clamping work pieces, comprise moving caliper (2), fixed caliper (1), screw mandrel (4), guiding nut (5), guide post parts such as (3), it is characterized in that guiding nut (5) and guide post (3) partable, there is serrated teeth the two sides of guiding nut (5), and spring (7) is housed, the pressue device that nylon block (6) and screw (8) are formed, the side of guide post (3) has serrated teeth, can engage with guiding nut.
