Embodiment Construction

[0009] The reference signs in the drawings of the description include: frame 1 , jaw 2 , push rod 3 , baffle plate 4 , and inclined block 5 .

[0010] Such as figure 1 As shown, a self-locking clamp in this embodiment includes a frame 1 , jaws 2 and a push rod 3 . The left end of the frame 1 is provided with a baffle plate 4, and the frame 1 is provided with a bar-shaped groove through which the jaws 2 are slidably connected with the frame 1. A slanting block 5 is arranged in the strip groove, and the inclined surface of the slanting block 5 is inclined to the right, and the angle of inclination is 30 degrees. Balls are arranged on the inclined surface of the slanting block 5, and the slanting block 5 is connected to the bottom of the bar groove by a spring. The push rod 3 is connected to the clamping jaw 2 .

[0011] When holding the push rod 3 to push the jaw 2 to the left, the jaw 2 slides to the left. When the jaw 2 contacts the slanting block 5, the slope of the slantin...

Abstract

The invention discloses a self-locking fixture which comprises a frame, a clamping jaw and a push rod. A baffle is arranged at one end of the frame, a slot is formed in the frame, the clamping jaw is slidably connected with the frame through the slot, an inclined block is arranged in the slot, inclined along the opposite direction of the baffle and connected at the bottom of the slot through a spring, and the push rod is connected on the clamping jaw. When hands hold the push rod to push the clamping jaw along the direction close to the baffle, the clamping jaw can slide along the direction close to the baffle. When the clamping jaw contacts with the inclined block, an inclined plane of the inclined block is inclined along the opposite direction of the baffle, so that the clamping jaw can press and pass the inclined block. The inclined block can upspring under the action of the spring and clamp the clamping jaw after the clamping jaw completely passes the inclined block, so that workpieces are clamped, and force applied to the clamping jaw does not need to be kept.

Description

technical field [0001] The invention belongs to the technical field of workpiece clamping devices. Background technique [0002] The fixture is used to locate and clamp the workpiece, mainly through the reciprocating swing of the jaws. However, the existing clamps do not have a self-locking function. When clamping the workpiece, the jaws need to be kept in a state of applying force, otherwise the workpiece will loosen, the purpose of clamping cannot be achieved, and it is inconvenient to operate. Especially for manual clamps, the operator needs to act on it all the time, which wastes manpower. Contents of the invention [0003] The invention provides a self-locking clamp to solve the problem that the existing clamp needs to keep exerting force on the jaws when clamping the workpiece. [0004] In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions: A self-locking fixture, comprising a frame, jaws and a pu...
