Abstract
The utility model provides a clamp which can adjust the jaw opening quickly and carry out continuous full travel clamping of the work piece. The utility model comprises the parts of a movable clamp body, a fixing clamp body, a screw shaft, a nut, etc. The utility model has the advantages that the nut and the screw shaft can be disengaged or engaged in full travel; when the nut and the screw shaft are engaged, the clamp can carry out the full travel spiral propelling clamping as the plain clamp; when the nut and the screw shaft are disengaged, the movable clamp body can slide freely relative to the fixing clamp body, and the quick adjustment of the jaw opening can be accomplished by pushing and drawing the movable clamp body. The disengagement and the engagement can be accomplished only through the rotation of the screw shaft.
Description
The utility model relates to a kind of mechanical grip instrument, but particularly a kind of quick adjustment aperture, the vice of the continuous clamping work pieces of total travel.
The tradition vice is to utilize screw mandrel, the screw of fixing pairing to carry out transmission, and in one week of rotary screw rod, the vice aperture can only change a screw mandrel pitch, and translational speed is slow, inefficiency.And the fast tighten vice of prior art, though can realize the quick adjustment of span of jaw, complex structure, functional reliability are poor, particularly can't carry out big stroke to tighten continuously, and when clamping the bigger workpiece (as spring) of distortion, the work that can not be satisfied with.
Task of the present invention provides a kind of novel vice that overcomes above-mentioned prior art vice defective, and it can realize that vice aperture quick adjustment and total travel continuous feed clamp, and it relaxes, locks, clamps only needs can realize by the rotating screw bolt axle.
Main points of the present utility model are: with the screw rod nut engaged be the eccentric nut of inside and outside circle decentraction, the endoporus of eccentric nut is greater than the external diameter of screw rod, eccentric nut is installed on the fixed caliper by support, under the drive of ratchet mechanism, eccentric nut rotates within the specific limits around the center of cylindrical, the endoporus center is changed, the screw thread of nut is the meshing or disengaging with screw flight with the variation of endoporus center, when nut and screw rod are meshing, the rotating screw bolt axle can promote the moving caliper clamping work pieces that advances, when nut and screw shaft disengaging, screw shaft and nut can axially be free to slide, and the push-and-pull moving caliper can carry out the quick adjustment of span of jaw.
Task of the present utility model realizes (referring to accompanying drawing 1) by following structure.
The utility model is made up of moving caliper (1), fixed caliper (2), screw shaft (3), eccentric nut (4), support (5), banking pin (6), group pearl (7), accent power spring (8), accent power screw parts such as (9).
Support (5) is installed on the fixed caliper (2), the cylindrical of eccentric nut (4) cooperates with the endoporus of support (5), eccentric nut (4) can freely rotate relative to screw shaft (3) and support (5), on eccentric nut (4), be processed with stroke limit groove (10), by being installed in the slewing area of the relative support (5) of spacer pin (6) restriction eccentric nut (4) on the support (5).On eccentric nut (4), be equipped with and dial pearl (7), transfer power spring (8) and transfer power screw (9), be processed with V-type groove (11) on screw shaft (3), rotating screw bolt axle (3) can be by the ratchet mechanism drive eccentric nut rotation of dialling pearl (7), transferring power spring (8), transferring the V-type groove (11) on power screw (9) and the screw shaft (3) to constitute jointly.
When needs quick adjustment vice aperture, counter-clockwise direction rotating screw bolt axle (3), dialling under pearl (7) drive, eccentric nut (4) towards lower dead center (be the eccentric nut inner hole centreline touch the bottom and with the screw shaft dead in line) rotate, eccentric nut (4) inner hole centreline reduces, the screw thread (or teeth groove) that is installed in the screw shaft (3) on the moving caliper (1) breaks away from gradually with the screw thread (or teeth groove) that is connected the last eccentric nut (4) of fixed caliper (2), when eccentric nut arrives lower dead center, be subjected to banking pin (6) and stopper slot (10) restriction (referring to accompanying drawing 2), eccentric nut (4) no longer is rotated further (V-type groove (11) overload of dialling on pearl (7) and the screw shaft surmounts), so can guarantee screw shaft (3) and eccentric nut (4) abundant disengaging (so the time center line of eccentric nut and screw shaft dead in line and eccentric nut endoporus greater than the external diameter of screw rod), push away this moment, draw moving caliper, can realize the quick adjustment of vice aperture.
When the needs clamping work pieces, clockwise direction rotating screw bolt axle (3), dialling under pearl (7) drive, eccentric nut (4) towards top dead centre (be eccentric nut (4) inner hole centreline peak and with screw shaft axis generation maximum deviation) rotate, eccentric nut (4) inner hole centreline is raised, the screw thread (or teeth groove) that is installed in the screw shaft (3) on the moving caliper (1) is meshing gradually with the screw thread (or teeth groove) that is connected the last eccentric nut (4) of fixed caliper (2), when eccentric nut arrives top dead centre, be subjected to the restriction of banking pin (6) and stopper slot (10), eccentric nut (4) no longer is rotated further (V-type groove (11) overload of dialling on pearl (7) and the screw shaft surmounts), so can guarantee the effectively meshing of screw shaft (3) and eccentric nut (4).At this moment, be rotated further screw shaft (3), can realize the continuous clamping of long stroke.
Advantage of the present utility model is: can realize the adjusting of vice aperture rapidly, only need the rotating screw bolt axle, can realize the function that relaxes, locks, clamps.When lax, by pushing away, draw moving caliper, can be in total travel fast moving (whole process only takes 1 second and can finish).During locking, can on the total travel optional position, clamp, can realize that particularly the total travel continuous feed clamps.And have characteristics simple in structure, reliable operation.
Implement the utility model and do not need special technique and special material.Processed one in model machine, result of use is fine.
Claims (3)
1, a kind of quick total travel grip vice, it is made up of parts such as moving caliper, fixed caliper, screw shaft, eccentric nut, support, ratchet mechanisms, it is characterized in that with eccentric nut adjusting screw(rod) axle and nut making jaw produce the screw mechanism that clamping force and screw shaft and nut can freely break away from from, the eccentric stiffener that closes.
2, quick total travel grip vice according to claim 1, it is characterized in that said eccentric stiffener comprise be connected on the fixed caliper, screw thread that endoporus is processed with to be cooperated with screw shaft or the eccentric nut of teeth groove and inside and outside circle decentraction, eccentric stiffener also comprises and is used to control the relative support of eccentric nut (also relative fixed caliper) slewing area, rack-mount banking pin and the stopper slot of processing on the eccentric nut cylindrical respectively.
3, quick total travel grip vice according to claim 1 is characterized in that said screw mechanism comprises the nut of internal orifice dimension greater than the screw shaft external diameter.
