Component fixing device

Abstract

The invention discloses a component fixing device. The component fixing device comprises a bottom plate, a fixed clamping block, a movable clamping block and a pushing device. The bottom plate is in astrip shape, the fixed clamping block is fixed to one end of the bottom plate. Sliding grooves in the length direction of the bottom plate are formed in the two sides of the bottom plate. The movableclamping block is provided with two sliding blocks matched with the different sliding grooves correspondingly. Matched faces formed by the side faces of the sliding grooves and the bottom faces of the sliding blocks are arc faces. In the depth direction of the sliding grooves, the highest point of the position of each arc face is located between the opening end of each sliding groove and the bottom end of each sliding groove. Two sliding grooves are formed in each side of the bottom plate, and the two sliding grooves located in the same side of the bottom plate are located in the upper end and the lower end of the bottom plate correspondingly. The upper end and the lower end of the bottom plate are different in width. The connecting manner of the fixed clamping block and the pushing device and the connecting manner of the pushing device and the bottom plate are detachable connecting forms. According to the structure, when component clamping is finished, uniformity of stress of variouspoints on the clamping face is facilitated. Stability of the relative position of the fixed clamping block and the movable clamping block is facilitated, and meanwhile the service life is long.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a component fixing device. Background technique [0002] In the process of mechanical manufacturing, the device used to fix the processing object so that it occupies the correct position to accept construction or inspection is generally called a fixture, also known as a jig. In a broad sense, any process in the process of workpiece production, inspection or maintenance, the device used to quickly, conveniently and safely install the workpiece can be called a fixture. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. [0003] In the prior art, a bench vise is a kind of universal fixture, and is an indispensable clamping device on a fitter's bench. Although the bench vise can clamp larger workpieces and provide sufficient clamping force, for parts with high dimensional accuracy, the bench vise clamp During the holding tim...

Problems solved by technology

[0004] In the above-mentioned prior art, for parts with high dimensional accuracy, when the parts are clamped by the bench vise without using other cushioning objects to wrap the parts, the force on the jaws of the bench vise is uneven at different positions. It is easy to cause the problem that the dimensional accuracy of the parts is damaged, the invention provides a part fixing device
