Adjustable positioning device for internal welding of small tin furnace

Abstract

The invention discloses an adjustable positioning device for internal welding of a small tin furnace, which comprises a furnace body, hinge seats are arranged on both sides of the surface of one end of the furnace body, a U-shaped frame is hinged to the surfaces of the hinge seats, sliding grooves are formed in both side surfaces of the U-shaped frame, rollers are mounted on both side surfaces of both ends of the sliding grooves in a rolling manner, and the rollers are movably connected with the furnace body. A transverse rod is fixedly connected to the surface of one side of the rolling wheel, connecting rods are fixedly connected to the surfaces of the two ends of the transverse rod, a connecting plate is fixedly installed on the surface of one end of each connecting rod, a transverse adjusting groove is formed in the surface of one end of each connecting plate, and a fixing sleeve is fixedly installed on the surface of the other end of each connecting plate; and a sliding sleeve is slidably mounted on the side face of the transverse adjusting groove, sliding rods are slidably mounted on the side faces of the fixed sleeve and the sliding sleeve correspondingly, and a clamping block is fixedly connected to the surface of one end of each sliding rod, so that the use convenience and stability can be greatly improved, and the welding positioning safety is guaranteed.

Description

technical field [0001] The invention relates to the field of small tin furnaces, and more specifically relates to an adjustable positioning device for welding inside a small tin furnace. Background technique [0002] In the process of circuit board production and local maintenance and processing, it is necessary to solder and position the pins of components. Generally, a small tin furnace is used for operation, and it can be directly put into the circuit board for comprehensive welding, which has high efficiency. In order to ensure safety Stable type, you need to use a positioning device to position the circuit board, and then insert it into the solder liquid in the small tin furnace. [0003] However, most of the existing small tin furnace positioning devices are simple splint structures, which are separated from the small tin furnace for positioning. This is not only troublesome for clamping and positioning, the stability is poor, and it is easy to misalign with the openin...

Problems solved by technology

[0003] However, most of the existing small tin furnace positioning devices are simple splint structures, which are separated from the small tin furnace for positioning. This is not only troublesome for clamping and positioning, the stability is poor, and it is easy to misalign with the opening of the small tin furnace, causing the circuit board to fail. Put it in the welding liquid stably, which will affect the operation, cause the pins of components to be misplaced or fall off, which is not conducive to use, and the surface of the welding liquid is easy to oxidize and peel during operation, which needs to be scraped off separately, which is troublesome and needs to be improved
