Description

Technical Field

[0001] The utility model belongs to the technical field of wave soldering, and specifically relates to an elastic pressing part for wave soldering tooling. Background Art

[0002] Wave soldering refers to melting soft solder (lead-tin alloy), which is sprayed into a solder wave peak of the designed requirements by an electric pump or an electromagnetic pump, or can be formed by injecting nitrogen into the solder bath, so that a printed circuit board pre-loaded with components passes through the solder wave peak to achieve the mechanical and electrical connection between the component solder terminals or pins and the printed circuit board pads through soft soldering. When performing wave soldering, it is necessary to tightly fix the printed circuit board through a pressing part. Currently, the pressing head of the pressing part is fixedly installed with the sliding rod, and the connecting sleeve sleeved on the top of the sliding rod is connected to the workbench. In use, the pressing head is a vulnerable part. When it is damaged, the entire pressing part needs to be replaced, resulting in waste of parts. Moreover, the pressing part is fixed to the workbench by interference fit or other means, and it is difficult to disassemble during replacement, making it inconvenient to use. For this reason, we propose an elastic pressing part for wave soldering tooling to solve the above problems.

[0003] The existing patent (application number: CN202220302062.8) proposes an elastic pressing part for wave soldering tooling, including a sliding rod. One end of the sliding rod is slidably sleeved with a connecting sleeve, and the sliding rod penetrates through the connecting sleeve and is sleeved with a nut head. A fastening mechanism is installed between the sliding rod and the connecting sleeve. The sliding rod is connected to the pressing head through a threaded structure, and a pressing spring is sleeved on the sliding rod between the pressing head and the connecting sleeve. The connecting sleeve is sleeved in the mounting hole on the workbench. After the pressing spring is sleeved on the sliding rod, the sliding rod passes through the connecting sleeve and is connected to the nut head, thereby installing the sliding rod and the connecting sleeve. At this time, the sliding rod squeezes the fastening mechanism, thereby fixing the connecting sleeve on the workbench. Then, the pressing head is threadedly sleeved at the bottom of the sliding rod. In use, the pressing head pushes the sliding rod, thereby compressing the pressing spring. The sliding rod slides along the connecting sleeve, facilitating the placement of the printed circuit board. Then, the pressing head presses the printed circuit board under the pressure of the pressing spring. When the pressing head is damaged, it can be directly separated from the sliding rod through the threaded structure, facilitating replacement.

[0004] The existing elastic pressing parts for wave soldering tooling usually use springs as the elastic force source, and achieve the pressing and loosening of the printed circuit board through the compression and release of the springs. However, since the elastic force of the springs is fixed and cannot be adjusted according to the actual use situation, in actual applications, there are often situations where the pressing force is insufficient or excessive, resulting in unstable welding quality or damage to the printed circuit board.

[0005] In view of this, this application is specifically proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an elastic pressing part for wave soldering tooling to achieve the required purpose.

[0007] To solve the above technical problems, an elastic pressing member for a wave soldering tooling provided by the utility model includes a sliding rod, a pressing head is detachably connected to the top end of the sliding rod, a mounting seat is detachably connected to the bottom end of the sliding rod, a pressing spring and a sliding ring are sleeved on the outer part of the sliding rod, one end of the pressing spring abuts against the bottom surface of the pressing head, the other end of the pressing spring abuts against the top surface of the sliding ring, a plurality of locking claws are fixedly arranged on the bottom surface of the sliding ring in an annular array, a clamping ring sleeve is sleeved on the outer part of the locking claws, and an adjusting screw sleeve is sleeved on the outer part of the clamping ring sleeve, and the adjusting screw sleeve is threadedly sleeved on the outer part of the sliding ring.

[0008] Further, an installation screw is fixedly connected to the top end of the sliding rod, a retaining ring is fixedly installed on the outer edge of the bottom end of the installation screw, and a threaded hole for the installation screw to be screwed into is arranged inside the pressing head. The cooperation of the provided installation screw and the retaining ring facilitates the installation and disassembly of the pressing head.

[0009] Further, the mounting seat is sleeved on the bottom end of the sliding rod, a positioning screw is fixedly connected to the bottom end of the adjusting screw sleeve, a through hole for the positioning screw to pass through is formed in the mounting seat, and a positioning nut is threadedly connected to the end of the positioning screw extending outside the mounting seat through the through hole. In order to facilitate the installation of the mounting seat on the processing bed, the installation efficiency is improved, and great convenience is brought to the assembly personnel.

[0010] Further, a flange is formed on the outer surface of the clamping ring sleeve, and the clamping ring sleeve and the adjusting screw sleeve are matched through the flange. In order to ensure that the vertical movement of the adjusting screw sleeve can drive the clamping ring sleeve to displace synchronously.

[0011] Further, the inner surface of the clamping ring sleeve is of a conical surface structure, and the outer surface of the locking claw is adapted to the inner surface of the clamping ring sleeve. In order to ensure that the clamping ring sleeve clamps the locking claw on the outer wall of the sliding rod.

[0012] Further, an external thread is integrally formed on the outer surface of the sliding ring, and an internal thread adapted to the external thread on the outer surface of the sliding ring is integrally formed on the inner surface of the adjusting screw sleeve.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art.

[0014] In the present utility model, by rotating the adjusting sleeve, it can undergo a threaded displacement along the sliding ring. During the movement of the adjusting sleeve, it can drive the clamping sleeve to undergo a vertical displacement. With the displacement of the clamping sleeve, under the action of the conical surface fit, the locking claws at the lower part of the sliding ring contract and hold the sliding rod, enabling the position of the sliding ring on the sliding rod to be adjusted. Furthermore, the compression deformation amount of the compression spring can be adaptively adjusted. This new type of elastic pressing member for wave soldering tooling can automatically adjust the elastic force according to factors such as the thickness of different printed circuit boards and welding process requirements to ensure the welding quality and stability.
