Description

Technical Field

[0001] The utility model mainly relates to the technical field of control valve skeleton processing equipment, and specifically relates to a positioning and pressing tooling for a skeleton used for winding wires. Background Technique

[0002] A control valve consists of two main assemblies: a valve body assembly and an actuator assembly (or actuator system), and is divided into four major series: single-seat series control valves, double-seat series control valves, sleeve series control valves, and self-acting series control valves. Different types of control valves are applicable to different occasions. Among them, the valve core in the control valve is a valve part that realizes the basic functions of direction control, pressure control, or flow control by means of its movement.

[0003] The valve core in the control valve mainly consists of a skeleton, copper wires, terminals, and a housing. During the assembly of the valve core, it is necessary to helically wind the copper wires around the skeleton. During the winding process, it is necessary to position the skeleton to prevent the skeleton from accidentally falling off the driven rotating shaft. In order to avoid sliding friction between the clamping block used for positioning and the skeleton during the rotation of the skeleton, resulting in wear on one side surface of the skeleton, generally, a certain gap is left between the clamping block and the skeleton. However, currently, since the clamping block is driven by a cylinder to move towards the skeleton side, it is difficult to determine the size of the gap. Sometimes, the size is too large, which causes the skeleton to shake along the axis on the rotating shaft, affecting the helical winding of the copper wires and making the wiring chaotic. Sometimes, the size is too small, which will cause friction with the surface of the skeleton, resulting in wear and affecting the outer tube, reducing the product quality. Summary of the Utility Model

[0004] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution significantly different from the existing technology. Specifically, the utility model mainly provides a positioning and pressing tooling for a skeleton used for winding wires to solve the technical problem that due to the drive of the cylinder, it is difficult to determine the size of the gap, affecting the product quality, as mentioned in the above background technique.

[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows:

A placing groove is arranged at the front end of the limiting column. A ball is arranged in the placing groove. A spring is arranged between the ball and the inner wall of the placing groove.

[0007] Furthermore, the limiting assembly also includes a mounting plate, which is sleeved on the end of the limiting clamp, and the mounting plate and the mounting block are both mounted on the moving beam by bolts.

[0008] Furthermore, each of the driving assemblies includes a pulling rod and a supporting frame, each of the pulling rods is provided with a stabilizing frame, each of the stabilizing frames is slidably connected to a limiting opening, and the limiting opening is provided on a side wall of the supporting frame.

[0010] Furthermore, a threaded column is provided at the front end of each pulling rod, and each threaded column is threadedly connected to a connecting plate.

[0011] Furthermore, each of the connecting plates and the movable crossbeam is connected via bolts.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0023] Please refer specifically to the attached Figures 1-4

[0024] With the above structure, when winding the wire around the skeleton inside the control valve spool, reasonable limitation of the skeleton can be achieved, leaving a certain gap, ensuring the normal rotation and wire winding of the skeleton, avoiding friction with the side surface of the skeleton and causing wear, effectively solving the problem of uncontrollable movement amplitude caused by the drive of the cylinder 3, and having a stable structure, convenient operation, and certain practical value.

[0025] The specific operation is as follows. First, put the skeleton on the wire-winding rotating shaft 1, then turn on the cylinder 3. Subsequently, pull the moving crossbeam 21 towards this side of the wire-winding rotating shaft 1 through the pulling rod 221. The ball 237 will first touch one end of the wire-winding rotating shaft 1. At the same time, under the action of the spring 238, it serves the purpose of small-amplitude regulation and "soft contact", so that there is a certain safety gap between the front end of the limit clamping cylinder 232 and the skeleton. Then, the driving device can be turned on to make the wire-winding rotating shaft 1 drive the skeleton to rotate and wind the wire.

[0026] Please refer specifically to Appendix Figure 1 and Appendix Figure 2 , each of the driving components 22 includes a pulling rod 221 and a support frame 224. A stabilizing frame 223 is arranged on each pulling rod 221. Each stabilizing frame 223 is slidably connected to a limit opening 225. The limit opening 225 is arranged on the side wall of the support frame 224. Through the mutual cooperation between the stabilizing frame 223 and the limit opening 225, the stability of the linear movement of the moving crossbeam 21 back and forth is improved. A cylinder 3 is installed on each support frame 224 through bolts, and the output end of the cylinder 3 is connected to one end of the corresponding pulling rod 221. Through the cylinder 3, driving force is provided for the movement of the moving crossbeam 21. A threaded column 222 is arranged at the front end of each pulling rod 221. Each threaded column 222 is threadedly connected to a connecting plate 24. Each connecting plate 24 and the moving crossbeam 21 are connected through bolts. Through the mutual cooperation between the connecting plate 24 and the threaded column 222, one end of the pulling rod 221 is installed on the moving crossbeam 21.

[0027] Please refer specifically to Appendix Figure 1 and Appendix Figure 3 , the limiting component 23 further includes a mounting plate 233. The mounting plate 233 is sleeved on the end of the limit clamping cylinder 232. The mounting plate 233 and the mounting block 231 are both installed on the moving crossbeam 21 through bolts. Through the mutual cooperation between the mounting plate 233 and the mounting block 231, a detachable connection method is realized, and the limit clamping cylinder 232 can be quickly installed on the moving crossbeam 21, which is very convenient and fast.
