Abstract
Description
Technical Field
[0001] The utility model mainly relates to the technical field of control valve spool processing equipment, and specifically relates to a wire winding and cutting mechanism based on a skeleton. 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, the copper wire needs to be spirally wound around the skeleton, and after winding, the copper wire is cut. Currently, in existing wire winding equipment, the skeleton can be driven to rotate to achieve the purpose of automatic wire winding. However, when winding the copper wire, the copper wire needs to be spirally wound around the skeleton, so the position of the lead wire needs to move along the axis direction of the skeleton and be evenly wound around the skeleton. And due to the change of the lead wire position, the cutting position also needs to change accordingly. During this period, it requires staff to operate, adjust the lead wire position, and manually cut. Due to the large production volume in the factory, continuous operation and processing are required. For the staff, the labor intensity is relatively large, time-consuming and laborious, and manual operation is prone to errors, affecting 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 wire winding and cutting mechanism based on a skeleton to solve the technical problem that during the wire winding process in the above background technique, it is necessary for staff to manually adjust the lead wire position and manually cut, which is prone to errors and affects product quality.

[0024] Please refer specifically to the attached Figures 1-5 , a wire winding and cutting mechanism based on a framework, including a lifting plate 1 and a rotating shaft 2 in a wire winding device. A lead wire shearing device 3 is arranged on the lifting plate 1. The lead wire shearing device 3 includes a motor 31 and a support plate 32. The motor 31 is installed on the upper side of the lifting plate 1 through bolts. A threaded column 33 is arranged at the output end of the motor 31. The threaded column 33 is threadedly connected with a threaded barrel 34. A plurality of pneumatic scissors 35 are linearly arranged at equal intervals on the support plate 32. A lead wire assembly 36 is arranged on one side of each pneumatic scissors 35. And the back of the support plate 32 is connected to one end of the threaded barrel 34.
[0025] With the above structure, when winding the wire around the skeleton in the valve core, the introduction position of the copper wire can be automatically adjusted to meet the spiral winding mode on the skeleton, and the shearing point is synchronously adjusted for precise cutting. There is no need for manual operation by workers, which saves time and effort, improves the automation coverage and work efficiency, avoids errors caused by traditional manual operation, improves product quality, reduces the unqualified rate and scrap rate, and saves costs to a certain extent.
[0026] The specific operation is as follows. First, turn on the device that drives the rotating shaft 2. Then, the rotating shaft 2 drives the skeleton to rotate, and the copper wire is wound around the skeleton. At the same time, the motor 31 is started to drive the threaded column 33 to rotate. Under the constraint of the limiting convex block 371 and the limiting sliding groove 341, the relative position of the threaded column 33 and the threaded barrel 34 is changed, so that the threaded barrel 34 drives the support plate 32 to linearly move. Then, the wire guiding rod 362 on the support plate 32 pulls the copper wire to linearly move along the axis direction of the rotating shaft 2, so that the copper wire is spirally wound around the skeleton. When the winding is completed, the pneumatic scissors 35 beside the wire guiding rod 362 are started to cut the copper wire.
[0027] Please refer to the attached Figure 2 and the attached Figure 3 For details, the wire shearing device 3 further includes a first limiting ring 37 and a second limiting ring 38. Limiting convex blocks 371 are arranged on both sides of the inner wall of the first limiting ring 37. Each limiting convex block 371 is slidably connected to a limiting sliding groove 341. The limiting sliding grooves 341 are arranged on both sides of the outer wall of the threaded barrel 34. Through the mutual cooperation between the limiting convex block 371 and the limiting sliding groove 341, the constraint of the threaded barrel 34 is realized, so that the threaded barrel 34 can only linearly move. The second limiting ring 38 is slidably connected to a limiting column 39. One end of the limiting column 39 is connected to the back surface of the support plate 32. Through the mutual cooperation between the second limiting ring 38 and the limiting column 39, the stability of the movement of the support plate 32 is improved. The second limiting ring 38 and the first limiting ring 37 are both installed on the upper surface of the lifting plate 1 by bolts, which is convenient for disassembly and maintenance. A plurality of rectangular openings 321 are linearly arranged at equal intervals on the support plate 32. Through the design of the rectangular openings 321, the weight of the support plate 32 is reduced, which is convenient for the movement of the support plate 32.
[0028] Please refer to the attached Figure 2 and the attached Figure 4 For details, each wire guiding component 36 includes a pneumatic telescopic rod 361. The output end of the pneumatic telescopic rod 361 is provided with a wire guiding rod 362. A wire guiding hole 363 is arranged at the lower end of the wire guiding rod 362. Through the mutual cooperation between the pneumatic telescopic rod 361 and the wire guiding rod 362, the distance from the introduction end of the copper wire to the skeleton is changed, so as to adjust the tension of the copper wire.
[0029] The above description of the present utility model with reference to the accompanying drawings is exemplary. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
