Abstract

The utility model relates to the field of workpiece clamping devices, in particular to a sliding clamping device. The sliding clamping device comprises a base, wherein a driving mechanism and a clamping mechanism are arranged on the base. The driving mechanism comprises a pulling handle, a nut, a screw and a force applying structure. The clamping mechanism comprises a clamping claw and a centering claw. An operator pulls the pulling handle downwards so that a workpiece is clamped by the clamping claw, and then the force applying structure drives the centering claw to center the workpiece; and the operator pushes the pulling handle upward to drive the clamping claw and the centering claw to loosen the workpiece. Two composite springs with large compressibility are adopted to enable the workpiece to be clamped tightly, and workpieces with different thicknesses can be clamped.

Description

Sliding fixture

Technical field

The utility model relates to the Workpiece clamping device field, is specifically related to a kind of sliding fixture.

Background technology

Often need in the workpiece process at present workpiece is fixing after, carry out follow-up processing again, so sliding fixture is widely used in the workpiece manufacture field, and existing sliding fixture shortcoming has at present: 1. clamping work pieces instability; 2. can not clamp the workpiece of different-thickness.

The utility model content

When being to provide a kind of clamping work pieces, the purpose of this utility model can stablize sliding fixture smoothly when unclamping workpiece.

For achieving the above object, the technical solution of the utility model is: a kind of sliding fixture, comprise pedestal, and be provided with driving mechanism, clamp mechanism at pedestal, described driving mechanism comprises pull handle, nut, screw rod, force application structure, and described nut is provided with the inclined-plane and is fixed on the pull handle upper end; Described screw rod upper end is connected on the pedestal, and the lower end is through in the axial blind hole of pull handle; Described force application structure comprises complex spring and top cover, and the top cover upper surface is connected with complex spring, and the complex spring other end is connected on the pedestal; Described clamp mechanism comprises clamp jaw, centering jaw, and described clamp jaw has a chute, and is hinged on the pedestal, and clamp jaw one end and carriage are hinged, and carriage contacts by the inclined-plane with nut, and the clamping head of the clamp jaw other end contacts with workpiece surface; Described centering jaw is articulated on the pedestal, and an end and top cover lower surface offset, and the centering head of the centering jaw other end contacts with workpiece.

When adopting technique scheme, following advantage is arranged: 1. adopt the bigger constrictive complex spring can be so that more stable during clamping work pieces; 2. clamp jaw has a chute, thereby can regulate the workpiece that the clamp jaw position clamps different-thickness.

Further, when the venthole that pull handle radially is provided with blind hole communicates, can when decontroling workpiece, successfully up push away by pull handle.

Screw rod can be unloaded convenient for maintaining when further, screw rod and pedestal keep in repair by being threaded in.

Further, the surface that contacts with workpiece of centering jaw arranges annular knurl and can prevent effectively that workpiece from sliding.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is the sectional structure view of utility model sliding fixture.

The specific embodiment

As shown in Figure 1, a kind of sliding fixture comprises a kind of sliding fixture, comprise pedestal 1, be provided with driving mechanism, clamp mechanism at pedestal 1, described driving mechanism comprises pull handle 2, nut 3, screw rod 4, force application structure, and described nut 3 is provided with the inclined-plane and is fixed on pull handle 2 upper ends; Described screw rod 4 upper ends are connected on the pedestal 1, and the lower end is through in the axial blind hole of pull handle 2; Described force application structure comprises complex spring 5 and top cover 6, and top cover 6 upper surfaces are connected with complex spring 5, and complex spring 5 other ends are connected on the pedestal 1; Described clamp mechanism comprises clamp jaw 7, centering jaw 9, described clamp jaw 7 has a chute, and is hinged on the pedestal 1, and clamp jaw 7 one ends and carriage 8 are hinged, carriage 8 and nut 3 contact by the inclined-plane, and the clamping head of clamp jaw 7 other ends contacts with workpiece surface; Described centering jaw 9 is articulated on the pedestal 1, and an end and top cover 6 lower surfaces offset, and the centering head of centering jaw 9 other ends contacts with workpiece.

Concrete using method: workpiece is positioned on the sliding fixture, the pull handle 2 of leaving behind, complex spring 5 drives top cover 6, top cover 6 promotes centering jaw 9 rotations and makes workpiece centering, when leaving behind pull handle 2, the carriage 8 that contacts with the nut inclined-plane moves down, and inwardly puts thereby drive clamp jaw 7, can realize the clamping of workpiece; Upwards promote pull handle 2, simultaneously with carriage 8 jack-up, thereby driving clamp jaw 7 outwards puts, nut 3 collision centering jaws 9 make top cover move up, thereby compression combined spring 5, at pull handle 2 venthole that communicates with blind hole is set and guarantees that pull handle 2 up promotes smoothly, realizes unclamping of workpiece.

Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
