Description
Technical Field
The utility model relates to the field of machinary, especially, relate to clamping device, specifically indicate a F presss from both sides.
Background
At present in various mechanical frock centre gripping, carpenter's processing, spot welding work piece centre gripping field, various clamping device demands are bigger and bigger, generally adopt traditional F to press from both sides centre gripping work piece as clamping device, but traditional F presss from both sides also has its shortcoming, and the shortcoming lies in that traditional F presss from both sides centre gripping work piece location inconvenient, the clamping-force is poor, and stability can not be good, and is faced the work piece of soft material a bit, damages the work piece surface very easily, leads to the damage of spare part. Can not be applied to the field of fine workpieces, and has certain problem of positioning property. Many conventional F-clamps can only hold workpieces of a certain size and are not practical for workpieces that are oversized.
Therefore, the positioning is accurate, the clamping force is good, the surface of the workpiece can not be damaged, the stability is good, the F clamp can be used for clamping workpieces of various sizes, and the novel F clamp which can be suitable for the field of fine workpieces has practical significance.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the shortcoming of above-mentioned prior art, providing a location accurate, clamping-force good, can not damage workpiece surface, stability good, can be used for the work piece of the various sizes of centre gripping, can adapt to the novel F clamp in meticulous work piece field.
In order to achieve the above object, the utility model provides a F presss from both sides has following characteristics: comprises a movable part which is arranged on the relative fixed part and moves relative to the relative fixed part,
wherein, the movable part comprises a rotating component and a movable jaw connected with the rotating component;
the relative fixed part comprises a screw seat, and the rotating part is arranged inside the screw seat in a penetrating way through the internal thread of the screw seat.
Preferably, the relative fixing part further comprises a ruler rod for fixing the screw seat, and a fixed jaw oppositely fixed on the ruler rod and arranged opposite to the movable jaw, and the bottom of the movable jaw is slidably sleeved on the ruler rod.
Preferably, the fixed jaw is sleeved on the ruler rod and is relatively fixed through the supporting leg provided with the spring. The supporting legs can be pulled up to freely slide the fixed jaw back and forth to the corresponding position, and the supporting legs are locked by the springs to be fixed.
Preferably, the rotating component comprises a screw rod penetrating through the screw seat and a cross rod fixed with the screw rod.
More preferably, the movable jaw and the fixed jaw have the same height.
Preferably, the F clamp is an aluminum alloy F clamp.
Preferably, the other end of the ruler rod, which is opposite to the screw seat, is provided with a choke plug.
Adopt the utility model discloses a F presss from both sides, stability is good, and the location is accurate, design benefit, its regular jaw relatively fixed in on the chi pole, can slide on the chi pole, when the work piece size of needs centre gripping is great, can slide regular jaw to the chi pole on from movable jaw part far away and fixed through the supporting legs that has the spring, so alright with the work piece of various sizes of centre gripping, its lead screw that adopts to wear to locate the screw seat carries out the centre gripping as rotary part, the atress is balanced, can not bruise workpiece surface, just the utility model discloses a F presss from both sides for aluminum alloy F, and hardness is lower itself, also has the advantage of avoiding workpiece surface to bruise. Has practical value.

Detailed Description
In order to more clearly describe the technical content of the present invention, the following further description is given with reference to specific embodiments.
Fig. 1 is a schematic view of an overall structure of an F-clamp of the present invention, please refer to fig. 1, which includes a movable portion mounted on a relative fixed portion and moving relative to the relative fixed portion, wherein the movable portion includes a rotating member and a movable jaw 5 connected to the rotating member; the relative fixed part comprises a screw seat 3, and the rotating part is arranged inside the screw seat 3 in a penetrating way through the internal thread of the screw seat 3.
The opposite fixing part also comprises a ruler rod 7 for fixing the screw seat 3 through the rivet 4 and a fixed jaw 6 which is oppositely fixed on the ruler rod 7 and is opposite to the movable jaw 5, and the bottom of the movable jaw 5 is sleeved on the ruler rod 7 in a sliding way. The fixed jaw 6 is sleeved on the ruler rod 7 and is relatively fixed through a supporting leg 9 provided with a spring 10. The supporting feet 9 on the fixed jaw 6 are pulled up to freely slide the fixed jaw 6 back and forth to the corresponding position for clamping the workpiece, and the supporting feet 9 are locked by the spring 10 for relative fixation.
The rotating part comprises a screw rod 2 penetrating through a screw seat 3 and a cross rod 1 fixed with the screw rod 2. The movable jaw 5 is connected with the screw rod 2 through a cylindrical end set screw 11.
The movable jaw 5 and the fixed jaw 6 have the same height. The F clamp is an aluminum alloy F clamp.
The other end of the ruler rod 7 opposite to the screw seat 3 is provided with a choke plug 8.
The screw seat 3, the movable jaw 5, the fixed jaw 6, the ruler rod 7 and the supporting legs 9 are all made of aluminum alloy, and most of the parts are made of aluminum alloy, so that the F clamp is an aluminum alloy F clamp which is lighter 2/3 than a conventional F clamp, and is very convenient to carry and use.
Adopt the utility model discloses a F presss from both sides, stability is good, and the location is accurate, design benefit, its regular jaw relatively fixed in on the chi pole, can slide on the chi pole, when the work piece size of needs centre gripping is great, can slide regular jaw to the chi pole on from movable jaw part far away and fixed through the supporting legs that has the spring, so alright with the work piece of various sizes of centre gripping, its lead screw that adopts to wear to locate the screw seat carries out the centre gripping as rotary part, the atress is balanced, can not bruise workpiece surface, just the utility model discloses a F presss from both sides for aluminum alloy F, and hardness is lower itself, also has the advantage of avoiding workpiece surface to bruise. Has practical value.
The above-mentioned embodiments are preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and those skilled in the art should understand that they can make modifications, changes, combinations, substitutions, etc. without departing from the spirit of the present invention, which is also within the scope of the present invention as claimed in the appended claims.
