Abstract

The utility model relates to a multifunctional F clamp, which comprises a slide bar, a movable jaw, a screw rod, a cross arm, a floating presser foot, a stop block and a rivet, wherein the function of the traditional F clamp is single, one F clamp can only clamp one type of workpiece, and the limitation is large, the utility model adds a plurality of functions on the basis of the traditional F clamp, the clamp body of the traditional F clamp is replaced by the movable jaw, both ends of the F clamp can slide along the slide bar rapidly, the opening amount is larger, the clamping range is wider, both ends of the F clamp are provided with adjustable screw rods, the F clamp can be used under a plurality of conditions, not only can clamp common plane workpieces, but also can clamp two-side groove type workpieces such as channel steel, one end of the slide bar is riveted by the rivet, the other end is provided with a detachable stop block, thus, the movable jaw is not easy to fall off when in work, the movable jaw can be reversely mounted after the movable jaw is dismounted, can be used to reverse type work pieces such as supporting plane and recess, the utility model provides a simple structure, reasonable in design's multi-functional F presss from both sides, can not need the change instrument during centre gripping different grade type work piece, operation labour saving and time saving.

Description

Multifunctional F-shaped clamp

Technical Field

The utility model belongs to the technical field of manual hardware and tools technique and specifically relates to a multi-functional F presss from both sides.

Background

The traditional F clamp has single function, one F clamp can only clamp one type of workpiece, the limitation is large, the common F clamp can only clamp plane type workpieces, and when the two-side groove type workpieces need to be clamped, the F clamp special for clamping the two-side groove type workpieces needs to be replaced; when the workpiece needs to be supported outwards, a special supporting tool needs to be replaced, and time and labor are wasted.

Disclosure of Invention

The multifunctional F clamp is simple in structure and reasonable in design, does not need to be replaced when clamping different types of workpieces, and is time-saving and labor-saving in operation.

The technical scheme adopted by the invention is as follows: a multifunctional F clamp comprises a sliding rod, a movable jaw, a screw rod, a cross arm, a floating presser foot, a stop block and a rivet, wherein one end of the movable jaw is a square hole, the sliding rod penetrates through the square hole of the movable jaw to enable the movable jaw to slide on the sliding rod, the other end of the movable jaw is a threaded hole, the screw rod is fixed on the movable jaw through the threaded hole, one end of the screw rod is a ball head, the other end of the screw rod is provided with a circular through hole, the floating presser foot is riveted on the ball head at one end of the screw rod and can rotate around the ball head for different angles to clamp workpieces with different angle planes, and the cross arm penetrates through the circular through hole at the other.

Each slide bar is provided with 2 movable jaws, 2 screw rods, 2 floating presser feet and 2 cross arms. The utility model discloses a two move the jaw with 2, 2 screw rods, 2 floating presser feet and 2 cross arms pass through square hole connection on the slide bar, slide bar one end is by rivet fixation, the other end has a screw hole, dog one end is the cylinder, and there is the hexagonal counter bore, convenient dismantlement, the other end has the screw thread, screw hole through slide bar one end is fixed to the slide bar, play the effect that prevents two removal jaws landing, lift the dog off, can make two each removal jaws pass through dog one end and freely load and unload, when two remove when keeping silent the direction relative installation, both can the clamping plane class work piece like this, also can the clamping two face recess class work piece, when two remove when keeping silent reverse installations, can play the effect of outside support like this.

Detailed Description

The multifunctional F clamp comprises a sliding rod 6, a movable jaw 3, a screw rod 2, a cross arm 1, a floating presser foot 4, a stop dog 7 and a rivet 5, wherein one end of the movable jaw 3 is a square hole, the sliding rod 6 penetrates through the square hole of the movable jaw 3 to enable the movable jaw 3 to slide on the sliding rod 6, the other end of the movable jaw 3 is a threaded hole, the screw rod 2 is fixed on the movable jaw 3 through the threaded hole, one end of the screw rod 2 is a ball head, the other end of the screw rod is provided with a circular through hole, the floating presser foot 4 is riveted on the ball head at one end of the screw rod 2 and can rotate around the ball head at different angles to clamp workpieces with different angle planes, and the cross arm 1 penetrates through the circular through hole at the.

Each slide bar 6 is provided with 2 movable jaws 3, 2 screws 2, 2 floating presser feet 4 and 2 cross arms 1. 2 move the jaw 3, 2 screw rods 2, 2 float presser feet 4 and 2 cross arms 1 and connect on slide bar 6 through the square hole, slide bar 6 one end is fixed by rivet 5, the other end has a screw hole, dog 7 one end is the cylinder, and there is hexagonal counter bore, the convenient dismantlement, the other end has the screw thread, fix on slide bar 6 through the screw hole of slide bar 6 one end, play the effect of preventing two and remove 3 slips of jaw, lift off dog 7, can make two each move jaw 3 and pass through dog 7 one end and freely load and unload, when two move jaw 3 directions and install relatively, so both can the clamping plane class work piece, also can the clamping two-sided recess class work piece, when two move jaw 3 reverse installations, so can play the effect of outside support plane and recess class work piece.

When a workpiece is clamped by applying force inwards, the movable jaw 3 on the left side slides towards the workpiece, so that the floating presser foot 4 on the screw rod 2 leans against one side of the workpiece, then the movable jaw 3 on the other side is moved, the floating presser foot 4 on the screw rod 2 leans against the other side of the workpiece, the cross arm 1 is rotated, the screw rod 2 moves towards the workpiece through a threaded hole at one end of the movable jaw 3, and the floating presser foot 4 on the screw rod 2 is pushed to gradually clamp the workpiece; when a force is applied outwards to support a workpiece, the stop block 7 can be firstly detached, then the two movable jaws 3 are reversely arranged on the slide rod 6, the directions of the floating presser feet 4 on the screw rod 2 are respectively outwards, then the movable jaws 3 are moved, the two floating presser feet 4 are respectively leaned against two surfaces of the workpiece needing to be supported outwards, the cross arm 1 is rotated, the screw rod 2 is enabled to move outwards through the threaded hole at one end of the movable jaws 3, and the floating presser feet 4 on the screw rod 2 are pushed to gradually support the workpiece outwards.
