Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited thereto.
[0028] As shown in the figure, the present invention includes a clip body 1 , a small bracket 2 , a middle bracket 3 , a large bracket 4 , a special-shaped connector 5 , a star handle 8 and a connecting flange 11 . The clamp body 1 is composed of a horizontal platform and a vertical plane. Small support 2, middle support 3 and large support 4 are fixed on the vertical plane of clamp body 1 by small studs 10. The special-shaped connector 5 is placed in the through groove of the bracket, the tail is placed in the bracket, and the head is placed outside the bracket. The special-shaped connector and the through groove belong to the clearance fit. The head of special-shaped connector is fixed with nut 6 and support and nut 6 is positioned at outside the support. A lock washer 7 is also provided bet...

Abstract
The invention discloses a general fixture for laser impact reinforced flat samples, and belongs to the field of mechanical technologies and laser machining. The general fixture comprises a fixture body, a small bracket, a large bracket, a big bracket, a special-shaped connecting piece, a star-shaped handle and a connecting flange. According to specifications of samples, the samples are placed on corresponding stations; the horizontal distance of the special-shaped connecting piece is adjusted; through clamping by the star-shaped handle, the clamping of the samples can be finished; then, the surfaces of the samples and a laser beam are kept normally perpendicular; and a point to be treated is placed in a focusing point of the laser beam to finish the preparation before laser impact reinforcement. The fixture is simple in structure and convenient to operate, improves the clamping efficiency and the impact quality of the laser impact reinforced flat samples, is higher in flexibility, and is suitable for flat samples with lengths of 60-260 mm and laser impact lengths of smaller than 120 mm under single clamping.
Description
technical field [0001] The invention relates to the fields of mechanical technology and laser processing, in particular to a universal fixture for laser shock strengthening flat samples, which is suitable for clamping various flat samples. Background technique [0002] Laser shock strengthening technology is a high-tech technology that uses plasma shock waves generated by strong laser beams to introduce residual stress on the metal surface to improve metal fatigue resistance and corrosion resistance. Compared with the traditional shot peening technology, the laser shock peening technology has the following characteristics: high energy, high pressure, ultra-high strain rate; no mechanical and thermal pressure damage; affecting the depth of the layer; good surface quality; good controllability; environmental protection and no pollution. [0003] When carrying out the laser shock strengthening test, it is usually necessary to clamp the flat sample first, then adjust the relativ...
