Description

Technical Field

[0001] The utility model mainly relates to the technical field of control valve spool processing equipment, and specifically relates to a spool skeleton winding mechanism. Background Technique

[0002] A control valve consists of two main components: 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 spool inside 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 spool inside the control valve mainly consists of a skeleton, copper wire, terminals, and a housing. During the assembly of the spool, it is necessary to helically wind the copper wire around the skeleton. In the existing skeleton winding mechanisms, generally, the skeletons are wound one by one or a whole row of skeletons are wound. After the winding is completed, it is necessary to pause the winding equipment to replace the skeletons wound on the rotating shaft. The time used for pausing and replacing the skeletons throughout the day is relatively long, and the number of skeletons that need to be wound in the factory is large. This winding method that requires pausing to replace the skeletons greatly reduces the work efficiency. Content of the Utility Model

Two first motors are arranged on the lifting plate, and winding components are arranged below the two first motors and on the moving tray.

[0007] Further, each of the winding components includes a bottom plate, on the upper side of the bottom plate, there are a plurality of mounting openings and two first positioning openings, and on the lower side of the bottom plate, there are two second positioning openings. Inside the first positioning openings, there are clamping members and rotating shafts rotatably connected inside the clamping members, and between adjacent rotating shafts, they are connected by pulleys and belts.

[0008] Further, a third motor is also provided on the bottom plate, and the third motor is connected to one end of the corresponding rotating shaft.

[0009] Further, at the output end of each first motor, there is a connecting shaft, and at the lower end of each connecting shaft, there is a positioning block, and the positioning block can fit with the first positioning opening and the second positioning opening.

[0024] Please refer specifically to the attached Figures 1-5 A spool valve skeleton wire winding mechanism includes a skeleton limiting mechanism 1. A replaceable wire winding device 2 is arranged on one side close to the skeleton limiting mechanism 1. The replaceable wire winding device 2 includes a main body bracket 21 and a moving tray 25. The main body bracket 21 is installed with a cylinder 22 through bolts. The output end of the cylinder 22 is provided with a lifting plate 23, and both sides of the lifting plate 23 are slidably connected to the inner wall of the main body bracket 21. Two first motors 24 are arranged on the lifting plate 23, and wire winding assemblies 3 are arranged below the two first motors 24 and on the moving tray 25.

[0025] Through the above structure, during the process of machining the control valve spool, the wire winding on the skeleton can be continuously carried out, reducing the time for placing the skeleton on the rotating shaft 33, greatly improving the working efficiency, meeting the production requirements of the factory for a large number of skeletons, reducing unnecessary time waste, and having a stable structure, easy to operate, high degree of automation, and having a certain market prospect.

[0026] The specific operation is as follows. First, turn on the third motor 34 inside the wire winding assembly 3 under the lifting plate 23. Then, through the mutual cooperation between the pulley and the belt, drive multiple rotating shafts 33 to rotate synchronously, driving the skeleton to rotate for wire winding. When the wire winding is about to end, the second motor 26 starts, and then the lead screw 261 rotates. Then, the nut seat 262 on the lead screw 261 drives the unprocessed wire winding assembly 3 on the moving tray 25 to move under the lifting plate 23. Subsequently, the air cylinder 22 pushes the lifting plate 23 downward, and then the processed wire winding assembly 3 on the connecting shaft 241 moves downward until the two sides of the bottom plate 31 on this wire winding assembly 3 fall into the positioning grooves 251 on the moving tray 25. Subsequently, under the action of the air cylinder 22, the positioning block 242 is pushed downward again, so that the positioning block 242 disengages from the second positioning port 313. Then, the first motor 24 rotates, and the positioning block 242 rotates 90 degrees. Then, the air cylinder 22 pulls the lifting plate 23 back to its original position, so that the positioning block 242 passes through the first positioning port 312. Subsequently, the nut seat 262 drives the un-wired skeleton to move to the position of the previously wired skeleton. Then, under the cooperation of the air cylinder 22 and the first motor 24, the positioning block 242 is driven to move downward, first passing through the first positioning port 312, then rotating 90 degrees, and then moving upward and getting stuck in the second positioning port 313. Then, the entire bottom plate 31 is pulled up to the wire winding position through the positioning block 242 for wire winding. At the same time, the nut seat 262 drives the already wired skeleton to one end of the side frame 27, and the wired skeleton is taken off and replaced with a new one.

[0027] Please refer specifically to Appendix Figure 2 and Appendix Figure 3, a connecting shaft 241 is provided at the output end of each of the first motors 24, a positioning block 242 is provided at the lower end of each of the connecting shafts 241, and the positioning block 242 can fit with the first positioning port 312 and the second positioning port 313. Through the mutual cooperation among the positioning block 242, the first positioning port 312, and the second positioning port 313, the lifting and lowering of the bottom plate 31 are realized, achieving the overall replacement of the winding assembly 3. Two groups of positioning grooves 251 are provided on the moving tray 25, and the positioning grooves 251 fit with the front edges on both sides of the bottom plate 31. Through the positioning grooves 251, the position of the bottom plate 31 on the moving tray 25 is limited. The replaceable winding device 2 further includes a second motor 26. A lead screw 261 and a side frame 27 at the front end of the lead screw 261 are provided at the output end of the second motor 26. A nut seat 262 is provided on the lead screw 261. The upper side of the nut seat 262 and the lower side of the moving tray 25 are connected by bolts. Through the mutual cooperation among the second motor 26, the lead screw 261, the nut seat 262, and the side frame 27, the linear drive of the winding assembly 3 is realized.

A clamping member 32 and a rotating shaft 33 rotatably connected within the clamping member 32 are provided in the first positioning port 312. Adjacent two rotating shafts 33 are connected by a belt pulley and a belt. Through the mutual cooperation between the belt and the belt pulley, the plurality of rotating shafts 33 rotate synchronously, achieving the purpose of winding multiple skeletons at one time.
