Description

Technical Field

[0001] The utility model belongs to the technical field of assembly of a switching power supply transmission mechanism, and in particular relates to a press-fitting fixture of a transmission mechanism spring component. Background Art

[0002] Many transmission mechanisms are used in switching power supplies. Spring assemblies are usually used in transmission mechanisms to provide transmission force. The spring assembly usually includes a transmission fish head and a retaining ring, a spring, a retaining ring and a pin that are sequentially sleeved on the transmission fish head. During the assembly process, the retaining rings need to be installed on both ends of the spring and sleeved on the transmission fish head. Then the spring is compressed and the pin is inserted into the pin hole at the end of the transmission fish head.

[0003] This operation is usually completed by assemblers using needle-nosed pliers. However, this assembly method is slow and inefficient, and if the needle-nosed pliers are not clamped firmly, it is easy to cause harm to the assemblers. Utility Model Content

[0034] Embodiment

[0035] As Figure 1-2 shown, a press-fitting fixture for a transmission mechanism spring assembly provided by the present utility model includes: a base, a frame, a quick clamp and a pressing block.

[0036] The base is used to be placed on the operating table. A first groove for placing the first end of the transmission fish head in the spring assembly is opened on the base, and the shape of the first groove matches the shape of the first end of the transmission fish head.

[0037] The frame is arranged on the base, and the quick clamp is installed on the frame. In the figure, the quick clamp is a schematic diagram of a push-pull quick clamp, and the handle of the quick clamp is not shown in the figure. Specifically, the quick clamp can have a dead point after the driving end moves down into place, and the dead point clamp of the quick clamp is used to clamp away, and it can maintain clamping after being pressed down into place. The pressure block is arranged on the driving end of the quick clamp, and is used to press down the retaining ring in the spring assembly. At this time, the pressure block always presses down the retaining ring in the spring assembly to facilitate exposing the pin hole in the transmission fish head.

[0038] The quick clamp is installed above the base through the frame, and a first groove is provided on the base to match the first end of the transmission fish head. Then, a pressure block is provided at the end of the quick clamp to press down the retaining ring on the transmission fish head. After being pressed into place, the quick clamp reaches the dead point and is locked. At this time, the pin can be quickly inserted into the pin hole of the transmission fish head, and then the quick clamp is bent upward to open the pressure block. The entire clamping process is realized through the first groove and the pressure block on the base. The operation is simple and safe, and the production efficiency can be doubled.

[0039] In order to ensure the stability of the transmission fish head when pressed down, a second groove corresponding to the first groove is opened at the bottom of the pressing block, that is, the second groove and the first groove are arranged on the same vertical line, and the second groove is used to accommodate the second end of the transmission fish head. When the pressing block is pressed down, the bottom of the pressing block moves downward to drive the retaining ring to move downward, and the second end of the transmission fish head is accommodated in the second groove.

[0040] In order to cope with spring assemblies of different specifications, the second groove is set to be detachable, specifically including a pressure head, which is detachably connected to the pressure block through a fastener, and the second groove is set on the pressure head. Second grooves of different sizes can be replaced by replacing the pressure head.

[0041] Similarly, the first groove on the base needs to be replaced synchronously, specifically including a mounting seat, the mounting seat is provided with the first groove, the mounting seat is embedded in the base, and by setting the first groove on the mounting seat and the mounting seat is embedded in the base, different sizes of the first groove can be achieved by replacing different mounting seats.

[0042] In order to ensure that the mounting seat is easy to take, an end edge abutting against the surface of the base is arranged on the outer periphery of the top of the mounting seat.

[0043] In this embodiment, a through groove is opened at the bottom of the pressure head in a direction perpendicular to the second groove, and the end of the through groove is connected to the front side of the pressure head. The through groove is used to expose the pin hole at the second end of the transmission fish head. When the pressure head moves downward to push the retaining ring in the spring assembly, the second end of the transmission fish head extends into the through groove, and the pin hole at the second end of the transmission fish head is exposed in the through groove, so that the pin can be easily inserted into the pin hole from the through groove.

[0044] It further includes two guide rods which are vertically arranged on the base, and the pressing block is slidably connected to the guide rods. The two guide rods and the driving end of the quick clamp are arranged in a triangle, and the guide rods can ensure that the pressing block moves up and down without shaking.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
