Tool fixture convenient to adjust for welding of circuit board

Abstract

The invention discloses a tool fixture convenient to adjust for welding of a circuit board. The tool fixture comprises a base, wherein a sliding groove is formed in a right side of an upper surface ofthe base, a sliding block is clamped to the sliding groove and is adaptive to the sliding groove, a first through hole is formed in a middle part of an inner side wall of the sliding groove and is arranged in a right side of the sliding groove, a bearing is fixedly embedded to a middle part of the inner side wall of the sliding groove and is arranged at a left side of the sliding groove, a firstnut is fixedly embedded to a lower part of a right side surface of the sliding block and is arranged in the sliding groove, a screw rod is arranged at a right side of the base and is adaptive to the first nut, and a left side surface of the screw rod sequentially penetrates through the first through hole and the first nut and extends to the sliding block. In the tool fixture convenient to adjust for welding of the circuit board, the screw rod is arranged, rotation of the screw can be converted to adjustment of distance between two studs under effects of the first nut and the sliding block, sothat the circuit board with different lengths can be clamped and fixed, and the purpose of reducing production cost is achieved.

Description

technical field [0001] The invention relates to the technical field of circuit board processing and manufacturing, in particular to a tooling fixture for circuit board welding that is convenient for adjustment. Background technique [0002] The names of circuit boards include ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, ultra-thin circuit boards, ultra-thin circuit boards and printed circuit boards. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances. [0003] In order to facilitate the welding of electronic components on the circuit board, mounting holes are generally opened on the corresponding positions of the circuit board. Before soldering electronic components on the circuit board, the circu...
