Abstract

A circuit board clamp capable of achieving rapid clamping comprises a base. The base is provided with a plurality of positioning blocks, an eccentric wheel, an eccentric rotating shaft, a movable guiding block, a positioning rod, a sliding block and a linear rail. The positioning rod is perpendicularly fixed to the movable guiding block. The plane formed by the center lines of the positioning rod and the movable guiding block is parallel to the upper end face of the base. The linear rail is fixed to the base. The positioning blocks are provided with workpiece limiting portions. The positioning blocks are fixed to the base in the mode of adapting to the workpiece shape arrangement mode. During clamping, the workpiece limiting portions make contact with the side walls of edges of workpieces, and the workpieces are arranged between the positioning blocks. Clamping force is mastered better, and the phenomenon that a brittle circuit board is damaged due to the fact that the clamping force is excessively large is avoided; the side walls of the workpieces are limited through the workpiece limiting portions of the positioning blocks, even stress on a circuit board during clamping is ensured, and the phenomenon that the circuit board is damaged due to local uneven stress is avoided.

Description

technical field [0001] The invention relates to the field of plate workpiece fixtures, in particular to a circuit board fixture for quick clamping. Background technique [0002] The use of circuit boards is very common, and its production process needs to go through many different environments, such as welding, painting, etc.; circuit boards often need to be reliably fixed in some processes. At present, many circuit boards on the market are made of resin and other materials, and the circuit boards made of them are relatively brittle. Therefore, when clamping is required, uneven force is easily applied to cause damage to the board body, and the scrap rate is high. Contents of the invention [0003] In view of the above-mentioned defects, the object of the present invention is to propose a circuit board fixture for fast clamping, which realizes fast clamping through the eccentric wheel, and each positioning block provides a limit point for the workpiece, which ensures unifor...
