Embodiment Construction

[0018] Such as figure 1 A self-locking manual compression fixture shown includes a support 1, and a mounting hole is provided on the support 1, a sliding shaft 2 is slidably disposed in the mounting hole, and a sliding shaft 2 is provided on the lower side of the sliding shaft 2. The wedge surface 2-1, the lower side of the sliding shaft 2 is directly opposite to the wedge surface 2-1, and the wedge indenter 3 is provided, and the inclination angle between the upper end surface of the wedge indenter 3 and the wedge surface 2-1 Similarly, the inclination angle range of the upper end surface of the wedge indenter 3 and the wedge surface 2-1 is 6°-10°, preferably 8°. The underside of the support 1 is provided with an elastic element 4 for resetting the wedge indenter 3, and the elastic element 4 is mounted on the support 1 by screws.

[0019] Such as figure 1 As shown, the elastic element 4 is a return leaf spring. Compared with the traditional cylindrical helical compression s...

Abstract

The invention discloses a self-locking type manual pressing clamp. The self-locking type manual pressing clamp comprises a support, wherein an installing hole is formed in the support, a sliding shaft is arranged in the installing hole in a sliding mode, a wedge surface is arranged on the lower side face of the sliding shaft, a wedge press head is arranged at the position, opposite to the wedge surface, of the lower side of the sliding shaft, the inclination angle of the upper end face of the wedge press head is equal to that of the wedge surface, the inclination angle of the upper end face of the wedge press head and the inclination angle of the wedge surface range from six degrees to ten degrees, and an elastic component is arranged on the lower side of the support, and is used for enabling the wedge press head to reset. The self-locking type manual pressing clamp has the advantages that clamping force is much higher than that of an ordinary manual clamp, self-locking performance is high, the shakeproof capacity is high, the design is reasonable, the structure is simple, operation is convenient, the size is small, the weight is light, disassembly and assembly are convenient, carrying is convenient, the service life is long, the application range is wide, the production cost is low, and popularization and use are convenient.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a clamp, in particular to a self-locking manual pressing clamp. Background technique [0002] At present, manual fixtures are still widely used in modern manufacturing because of their simple structure, low production cost, short manufacturing cycle, energy saving and environmental protection. However, the manual clamp has a fatal disadvantage, that is, due to the limited force of the human hand, its clamping force cannot be very large, so it cannot be compared with hydraulic, pneumatic and other motorized clamps. For example, for fixtures operated at high frequencies, the manual force is generally required to be less than 150N; for fixtures operated at low frequencies, the force applied by the hand should be limited to less than 600N. Otherwise, the labor intensity of the operating workers will be too large. Contents of the invention [0003] The purpose of the p...
