Referring to fig. 1-3, the present invention provides a V-shaped expanding locking clamp, which includes a clamp body 1, a pressing block 2 and a locking screw 3.
Referring to fig. 1 to 3, the clamp body 1 includes a base 11, a left fixing block 12 and a right fixing block 13, and the base 11 is horizontally disposed on the worktable 4. The base 11 is provided with a lower through hole 111 extending along the vertical direction and penetrating through the base 11, the lower through hole 111 is located at the center of the base 11, and the side wall of the lower through hole 111 is provided with lower threads. The lower end of the left fixed block 12 is fixedly connected with the left end of the base 11, and the lower end of the right fixed block 13 is fixedly connected with the right end of the base 11. The two opposite sides of the left fixed block 12 and the right fixed block 13 are enclosed to form an accommodating cavity, and the width of the left and right directions of the accommodating cavity is gradually reduced from top to bottom. In this embodiment, the left fixing block 12 and the right fixing block 13 have the same shape and are symmetrically disposed at the left and right ends of the base 11. Two opposite surfaces of the left fixed block 12 and the right fixed block 13 are inclined surfaces, and in this embodiment, the inclination angles of the two inclined surfaces are both 70 °.
Referring to fig. 1 to 3, in order to reduce the manufacturing cost and improve the compactness of the fixture, the base 11, the left fixing block 12, and the right fixing block 13 are integrally formed. The base 11, the left fixing block 12 and the right fixing block 13 are made of aluminum alloy with good plasticity.
Referring to fig. 1 to 3, the pressing block 2 is embedded between the left fixing block 12 and the right fixing block 13. In this embodiment, the pressing block 2 is provided with an upper through hole 21 at a position corresponding to the lower through hole 111, the upper through hole 21 is located at the center of the pressing block 2, and the side wall of the upper through hole 21 is provided with an upper thread matched with the lower thread. In this embodiment, the pressing block 2 is made of durable steel. In this embodiment, the pressing block 2 is a wedge-shaped pressing block, and the left and right side walls of the pressing block 2 are arranged in cooperation with the two opposite inclined surfaces of the left fixing block 12 and the right fixing block 13.
Referring to fig. 1 to 3, the locking screw 3 is vertically disposed, and a lower end of the locking screw 3 sequentially penetrates through the pressing block 2 and the base 11 and then is fixedly connected to the worktable 4.
