Abstract
The utility model belongs to a quick-operating woodworking fixture. The lower part of a fixing forceps body (13) is provided with a movable half nut which is matched with a screw rod. The movable half nut can be engaged with or disengaged from screw threads of the screw rod. The moving of the movable half nut is controlled by a turnover board on a movable forceps body. The utility model has the advantages of simple structure, convenient use, quick-operating realization of idle stroke and slow-operating workpiece clamping. The utility model enhances work efficiency. Because the screw rod adopts inner obliquity zigzag special type the crew threads, the screw rod can be fixedly and reliably clamped.
Description
The utility model relates to Woodworker clamp, more particularly is the snap-action Woodworker clamp.
Present Woodworker clamp is made up of fixed caliper, moving caliper, screw mandrel etc., feed screw nut and fixed caliper are integral, during use, the operator makes the caliper clamping work pieces by rotary screw rod, and this kind clamp structure is simple, but clamping work pieces speed is slow, time-consuming effort again, and the stroke of clamping work pieces is big more, and it is just outstanding more that this folder shortcoming shows.
The purpose of this utility model can be eliminated above-mentioned shortcoming in order to provide a kind of exactly, can snap-action, but slow motion again clamps the efficient height, positioning and reliable clamping snap-action Woodworker clamp.
In order to achieve the above object, screw mandrel of the present utility model (1) adopts the extraordinary screw thread of leaning angle zigzag.The bottom of fixed caliper (13) is provided with the half-nut (10) that cooperates with screw mandrel.
In " V " the type groove that is inserted in half-nut (10) bossing that the returning face plate of this device (11) is movable and the groove of nut gland (12), returning face plate is connected on the spring fast pulley (12) by split pin (15), the spring fast pulley connects with handgrip (3) on the moving caliper (6), the spring fast pulley is provided with scroll spring (14), one end of scroll spring connects with the spring fast pulley, and the other end connects with moving caliper (6).
This device is provided with the guide post (9) suitable with screw mandrel (1) length, and is linked together by fixing iron (16), and the top of moving caliper (6) is provided with detent rail (7) and trip bolt (4), and the screw thread leaning angle of screw mandrel (1) is generally 3 °～6 °.
The utility model is simple in structure, and is easy to use, and idle stroke can realize snap-action, but slow motion during clamping work pieces has greatly improved operating efficiency, and clamping firmly, reliable.
Below in conjunction with accompanying drawing the utility model is described further:
Description of drawings: Fig. 1 is the device cutaway view
Fig. 2 is an A-A cutaway view among Fig. 1
Fig. 3 is a B-B cutaway view among Fig. 1
This device is provided with screw hole in the centre of moving caliper (6), screw mandrel (1) is installed in the hole, it can only be rotated in the hole, and can not move axially, on the moving caliper (6) of screw hole both sides and fixed caliper (13), be provided with the guide post hole, guide post (9) connects with moving caliper, and can slide along the guide post hole of fixed caliper, the guide post other end and screw mandrel are connected by fixing iron (16), the bottom of fixed caliper (13) is fluted, screw mandrel is by passing through in the groove, and be provided with the half-nut (10) (showing) of band projection as Fig. 2, the screw thread of half-nut cooperates with screw mandrel and can move in groove, can mesh or break away from wire rod thread, the bossing of half-nut outwards is higher than the fixed caliper outer surface, and on fixed caliper, be provided with nut gland (12), the inside of nut gland and the bossing of half-nut are respectively established one " V " type groove, insert returning face plate (11) between two " V " type groove, returning face plate connects with the spring fast pulley (18) of moving caliper (6), and can in total travel, slide with moving caliper, moving caliper is established a through hole on (6), handgrip (3) is housed in the through hole, the spring fast pulley (08) and the returning face plate (11) of handgrip and moving caliper another side link up (showing as Fig. 3) with pin (15), scroll spring (14) is housed on the spring fast pulley, one end of scroll spring is fixed on the spring fast pulley, and the other end is stuck on the boss of moving caliper (6).
This device in use, grasp the screw mandrel head, hold handgrip (3) simultaneously, when firmly holding handgrip, handgrip can turn over a position, drive spring fast pulley (18) and returning face plate (11) simultaneously and rotate same position, scroll spring (14) screws, and this moment, the rotation of returning face plate made half-nut (10) move down a segment distance, broke away from wire rod thread, screw mandrel can before and after arbitrarily push-and-pull, realize the snap-action action.Unclamp handgrip (3) under the effect of scroll spring, make repositions such as handgrip returning face plate, make the screw-threaded engagement of half-nut and screw mandrel, can realize that slow motion clamps.
The screw thread of this device screw mandrel (1) adopts the extraordinary screw thread of the zigzag of 3 °～6 ° of introversions, and corresponding half-nut (10) also adopts identical screw thread, makes the engagement of half-nut and screw mandrel more reliable.
The top of the moving caliper of this device (6), be provided with detent rail (7) and trip bolt (4), detent rail is arranged in the groove on moving caliper (6) top, can rise and to fall, height by trip bolt (4) control detent rail, it mainly acts on is to the need timber of operation such as plane, and can be placed on the workbench, is located by detent rail.
