Description

Technical Field

[0001] The utility model belongs to the field of terminal processing, in particular to a high-precision terminal pitch-changing rotation mechanism. Background Art

[0002] High-precision terminals are electronic connection devices with high precision and high reliability. They are usually used for connections between electronic circuits and have functions such as transmitting signals and electrical energy. During their production and processing, multiple terminals need to be rotated with variable pitch. The current conventional application method requires two steps to achieve this. The first step is to rotate the terminals into place, and the second step is to reduce the spacing between the terminals. This structural method takes a long time to operate, has low efficiency, high cost, and is inconvenient to maintain.

[0003] Since the terminal is irregularly shaped and tilted, the traditional variable distance method requires two actions to complete this work, which is inefficient, costly, and has a complex structure. Therefore, a new device needs to be designed. Utility Model Content

[0006] A high-precision terminal pitch-changing rotation mechanism includes a support assembly for supporting pitch-changing operations, a pitch-changing assembly mounted on the support assembly for step-by-step pitch-changing operations, and four fixed assemblies for two-point position limiting and upward blowing. The four fixed assemblies have the same structure and differ only in appearance.

[0007] The variable pitch assembly includes a travel limit plate, a stepped groove is provided on the travel limit plate, a cylinder is installed under the travel limit plate, a connecting plate is provided at the output end of the cylinder, a push rod is installed behind the connecting plate, the push rod is stepped in shape, friction pads are provided on the upper and lower surfaces of the push rod, a limiting block is provided at the rear end of the push rod, a fixed seat is slidably installed on the outside of the push rod, and three sliding seats are evenly arranged behind the fixed seat.

[0008] Furthermore: the support assembly includes a base plate, and two support plates are symmetrically arranged on both sides of the base plate.

[0009] Furthermore: the fixing assembly includes an air intake seat, an air intake pipe is provided on one side of the air intake seat, a limit seat is installed on the air intake seat, a limit clamp is provided on one side of the top of the limit seat, an insertion rod is provided on one side of the limit clamp, and two air blowing ports are provided on the limit seat, and the air intake pipe is connected to the two air blowing ports through the inside of the air intake seat and the inside of the limit seat.

[0010] Furthermore: two sliding rods are symmetrically arranged on both sides of the travel limit plate, and the sliding seat is slidably connected to the sliding rods.

[0011] Furthermore: the fixing seat is located at the front end of the stepped groove and is restricted at the front end of the stepped groove.

[0012] Furthermore: the two blowing ports are respectively located on one side of the insertion rod and the inner side of the limiting clamp.

[0013] Compared with the prior art, the beneficial effects are:

[0014] 1. Through the setting of two-point limit and stepped push-to-change distance, the terminal is limited from two points to make it conform to the swing direction. No rotation is required. The distance change operation can be achieved by simply pushing the sliding seat to move equidistantly through the push rod and the stepped groove, which improves efficiency, saves costs and simplifies the structure.

[0015] 2. Through the setting of step-by-step pitch-changing operation, only one control cylinder is needed to realize the pitch-changing movement of multiple sliding seats;

[0016] 3. Through the setting of upward blowing and dropping, the terminals are automatically blown off, realizing automatic dropping. BRIEF DESCRIPTION OF THE DRAWINGS
