Abstract
The utility model discloses a special clamp. The special clamp comprises a clamp body, and is characterized in that the body is a trapezoid fixing frame, screw holes are respectively arranged in end walls of two sides of the trapezoid fixing frame, a threaded rod is arranged in the screw holes in penetrating mode, clamp heads are connected with inner end heads of the threaded rod, handles are arranged on outer end heads of the threaded rod, and outer ends of the clamp heads are respectively provided with a clamp portion. The special clamp can clamp a workpiece of a trapezoid structure conveniently.
Description
Technical field
The utility model relates to the special fixture that a kind of machine tooling is used.
Background technology
Be used for fixing processing object in the machine-building process, make it to be in correct position, the device to accept construction or to detect is referred to as anchor clamps, be called again jig, in a broad sense, any operation in technical process is used for rapidly, the device of convenient, safe installation workpiece, all can be described as anchor clamps, such as weld jig, inspection jig, assembling jig, jig etc., wherein jig is the most common, is called for short anchor clamps.On lathe during processing work, for the surface energy that makes workpiece reach the drawing regulation size, geometry and with other surperficial specification requirement such as relative-position error, workpiece must be installed (location) before the processing, clip (clamping).Anchor clamps are comprised of setting element (determining the tram of workpiece in anchor clamps), clamping device, tool setting induction element (determining relative position or the guiding tool orientation of cutter and workpiece), indexing means, Connection Element and clamp body (clamp base) etc. usually.
Anchor clamps can be divided into according to its handling characteristics: (1) universal anchor clamps, such as machine vice, chuck, sucker etc.; (2) specificity anchor clamps, commonly used have turning attachment, a fraise jig etc.; (3) flexible jig; (4) built-up jig.Anchor clamps often can run into the workpiece that profile is trapezoidal shape in processing is used the time, therefore need a kind of anchor clamps of special use to be used for clamping work pieces.
Summary of the invention
The utility model purpose provides a kind of special fixture that can clamp easily trapezoidal workpiece.
The technical solution of the utility model is: a kind of special fixture, comprise a chuck body, described body is trapezoidal fixed mount, offer respectively screw on the end wall of described trapezoidal fixed mount both sides, run through in the described screw and be provided with screw rod, described screw rod inner termination is connected with chuck, and described screw rod external end head is provided with handle, and described chuck outer end is respectively equipped with clamping part.
Further the described clamping part of technical scheme comprises the sawtooth that cooperatively interacts that is arranged at respectively two chuck outer ends.
In the technique scheme, it is inboard that workpiece to be processed is positioned over trapezoidal fixed mount, between two chucks, thereby by rotary screw so that the chuck of both sides inwardly rotate, and then clamping work pieces, because the chuck outer end is sawtooth, thereby the trapezoidal workpiece of preferably clamping.
The utility model has the advantages that:
1. the utility model is by arranging respectively screw rod in trapezoidal fixed mount both sides, and screw rod the inner is provided with chuck, and the chuck outer end is clamping part, thus screw rod rotation so that the chuck clamping work pieces, clamping part is sawtooth, thus the irregular workpiece of clamping surface easily;
2. the utility model is simple in structure, and is easy to use, and is easy to realize, is fit to promote the use of.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the structural representation of the utility model embodiment one.
Wherein: 1, trapezoidal fixed mount; 2, screw rod; 3, chuck; 4, handle; 5, clamping part.
The specific embodiment
Embodiment one: referring to shown in Figure 1, a kind of special fixture, comprise a chuck body, described body is trapezoidal fixed mount 1, offers respectively screw on the described trapezoidal fixed mount 1 both sides end wall, runs through being provided with screw rod 2 in the described screw, described screw rod 2 inner termination are connected with chuck 3, described screw rod 2 external end heads are provided with handle 4, and described chuck 3 outer ends are respectively equipped with clamping part 5, and described clamping part comprises the sawtooth that cooperatively interacts that is arranged at respectively two chuck outer ends.
The utility model in use, it is inboard that trapezoidal workpiece to be processed is positioned over trapezoidal fixed mount, between the chuck of both sides, the operator grasps rotatable handle, so that screw rod inwardly rotates, inwardly move thereby promote chuck, and then clamping work pieces, because the chuck outer end is provided with the zigzag clamping part, easily the irregular workpiece of clamping surface.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. special fixture, comprise a chuck body, it is characterized in that: described body is trapezoidal fixed mount (1), offer respectively screw on the end wall of described trapezoidal fixed mount (1) both sides, run through in the described screw and be provided with screw rod (2), described screw rod (2) inner termination is connected with chuck (3), and described screw rod (2) external end head is provided with handle (4), and described chuck (3) outer end is respectively equipped with clamping part (5).
2. a kind of special fixture according to claim 1, it is characterized in that: described clamping part comprises the sawtooth that cooperatively interacts that is arranged at respectively two chuck outer ends.
