[0023] Please refer to the attached Figure 1-4 A control valve needle assembly tooling includes a positioning support mechanism 1 and a driving mechanism 2, wherein the positioning support mechanism 1 includes a seat 11, and the driving mechanism 2 includes a hydraulic cylinder 21, and the hydraulic cylinder 21 is located on the vertical part of the seat 11, and a positioning block 12 is provided on the upper surface of the seat 11, and a socket 121 is provided at the center position of the positioning block 12, and a push rod 22 is provided at the output end of the hydraulic cylinder 21, and a coupling 23 is provided at the lower end of the push rod 22, and a mounting cylinder 24 is provided at the lower end of the coupling 23, and the central axis of the mounting cylinder 24 coincides with the central axis of the positioning block 12.

[0024] Through the above structure, during the assembly of the control valve armature, the needle body 3 is automatically driven to move in the direction of the needle head 4 for plug-in assembly, which effectively avoids the clamping and driving of the thinner needle head 4, reduces the probability of the needle head 4 being bent and scrapped, improves the efficiency of assembly, reduces costs, and does not require manual operation, thereby reducing labor intensity, saving time and effort, and has certain practical value.

[0025] The specific operation is as follows: first, insert the tip of the needle 4 into the socket 121 of the positioning block 12, with the end of the needle 4 facing upward, then insert the needle body 3 into the opening at the lower end of the mounting cylinder 24, and tighten the locking bolt 25 for positioning, then open the hydraulic cylinder 21, and then push the mounting cylinder 24 downward through the coupling 23, so that the circular hole at the lower end of the needle body 3 is inserted together with the end of the needle 4 to complete the assembly, and at the same time, the lower side of the coupling 23 is pressed just on the limiting pad 16.
