Abstract

The utility model discloses a combined clamp, which includes a clamp body, a screw, a clamp head and a hand lever as well as a stud, wherein a stepped hole is formed in the center of the clamp body, screw holes are formed at the upper and the lower ends of the clamp body, a round through hole is formed in the middle of the clamp body, and the diameter of the middle round through hole is greater than that of the screw hole; and the upper and the lower screw holes are in threaded connection with the upright stud, and the upper and the lower screw holes and the upright stud are locked through a lock nut. The utility model has the benefits that the combined clamp placed on a polygonal worktable can simultaneously clamp a plurality of workpieces and facilitates the simultaneous operation of many operators, thereby greatly improving the working efficiency, enlarging the use range, and achieving the advantages of simple structure and wide application range; and the combined clamp as the novel clamp can be made into the line products of different forms and sizes, thereby meeting the requirements of different customers.

Description

A kind of built-up jig

Technical field

The utility model relates to a kind of anchor clamps, is specifically related to a kind of built-up jig, belongs to the clamping device technical field.

Background technology

Often need a kind of anchor clamps to clamp in factory and have two plane-parallel workpiece; So that accomplish work such as welding, boring, recontour; Particularly can be fixed in the universal fixturing that clamps a plurality of workpiece on the polygon workbench, also not have this anchor clamps on the domestic and international market at present as far as we know.

Summary of the invention

The utility model satisfies user's needs in order to increase work efficiency, and a kind of built-up jig is provided, and can accomplish the clamping to a plurality of workpiece simultaneously.

The utility model solves the technical scheme that its technical problem adopted: a kind of built-up jig, comprise clamp, screw rod, chuck, hand lever, and it is characterized in that: it also comprises double-screw bolt; Said clamp center is provided with shoulder hole, and two ends are screwed hole up and down, and middle is the circle open-work, and middle circle open-work diameter is greater than the screwed hole diameter; Said two screwed holes up and down are threaded with the said double-screw bolt of vertically placing, and lock with locking nut.

Further, be arranged with above the said clamp more than or equal to four even number wing bodies, be arranged with below more than or equal to four even number wing bodies, the both wings body is relative up and down, is to be sidelong Π shape; Wing end of body is provided with screwed hole above the said clamp, is connected with said screw flight, is parallel to each other between each screw rod, and said screw rod lower end is equipped with said chuck, and the screw rod upper end is provided with horizontal round open-work, the said hand lever of movable placement in the circle open-work; Both wings end of body and screw rod upper grip are provided with boss relatively below the said clamp.

Further, said double-screw bolt is fixed on the chassis and perpendicular to the chassis.

Further, said chassis is threaded on the base.

The even number wing body that preferred said clamp is arranged with up and down can be 4,6,8.

The beneficial effect of the utility model is, this built-up jig is positioned on the polygon workbench, can clamp a plurality of workpiece simultaneously; Be convenient to many people and work simultaneously, thereby improved operating efficiency greatly, enlarged the scope of application; Have simple in structurely, advantages of wide application range is as a kind of novel clamp; Can make multi-form and series of products size, satisfy the needs of different user.

The specific embodiment

As depicted in figs. 1 and 2, a kind of built-up jig comprises clamp 3, screw rod 4, chuck 5, hand lever 11, and said clamp 3 centers are provided with shoulder hole, and two ends are screwed hole up and down, and middle is the circle open-work, and middle circle open-work diameter is greater than the screwed hole diameter; Said two screwed holes up and down are threaded with the double-screw bolt of vertically placing 1, and with locking nut 2 lockings.

Be arranged with above the said clamp 3 more than or equal to four even number wing bodies, below symmetry also be provided with more than or equal to four even number wing bodies, the both wings body is relative up and down, is to be sidelong Π shape; Wing end of body is provided with screwed hole above the said clamp 3, is threaded with screw rod 4, is parallel to each other between each screw rod 4, and said screw rod 4 lower ends are equipped with chuck 5, and screw rod 4 upper ends are provided with horizontal round open-work, the movable hand lever 11 of placing in the circle open-work; Both wings end of body and screw rod 4 upper grips 5 are provided with boss relatively below the said clamp 3.

Said double-screw bolt 1 is perpendicular to chassis 10 and fixing with chassis 10.Particularly, double-screw bolt 1 is welded on the chassis 10.

Said chassis 10 is threaded with base 9.Particularly, chassis 10 and base 9 usefulness bolts 8, nut 7, spring washer 6 are connected, and its connecting bolt 8 numbers are 4 to 8.

Embodiment 1: the wing body number that said clamp 3 is arranged with up and down is 4.

Embodiment 2: the wing body number that said clamp 3 is arranged with up and down is 6.

Embodiment 3: the wing body number that said clamp 3 is arranged with up and down is 8.

During work, workpiece is put on the bottom wing body boss, hand lever 11 is rotated on plane on chuck 5 alignment pieces, and screw rod 4 moves down, chuck 5 workpiece pressings; After processing workpiece, counter-rotation hand lever 11 unclamps workpiece, and it is unloaded.

This built-up jig is placed on the corresponding polygon workbench according to wing body number, is operated simultaneously by many people, thereby has improved operating efficiency greatly, has enlarged the scope of application.
