Description

Technical Field

[0001] This invention relates to the field of spring processing equipment technology, specifically to a multi-specification spring winding and forming and pitch adaptive adjustment device. Background Technology

[0002] Springs, as a common mechanical component, are widely used in various fields. Spring winding is one of the core processes in spring manufacturing. It is the process of processing spring steel wire into a spiral or other complex shape by winding equipment according to specific geometric parameters (such as wire diameter, number of turns, pitch, outer diameter, etc.).

[0003] Traditional spring coiling machines typically require manual pitch adjustment when coiling springs of different specifications. This method is inefficient and relies entirely on the operator's experience, resulting in poor product consistency. To address this, we propose a multi-specification spring coiling and pitch adaptive adjustment device. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-specification spring winding and pitch adaptive adjustment device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-specification spring winding forming and pitch adaptive adjustment device, comprising a base and an external control module, wherein a winding mechanism is installed at one end of the base, a feeding mechanism is installed at the other end of the base and located on the feeding side of the winding mechanism, and a pitch adjustment mechanism is installed above the winding mechanism.

[0006] The winding mechanism includes a drive box, and a spindle replacement assembly is installed at the output end of the drive box. A winding spindle is detachably installed inside the spindle replacement assembly. The winding mechanism is used to wind spring wire to form a spring.

[0007] The pitch adjustment mechanism includes an adjustment drive assembly with an adjustment wheel mounted at its bottom. The adjustment wheel acts on the spring wire to change the spring pitch. The pitch adjustment mechanism also includes an adaptive detection assembly, which is located at the other end of the winding spindle and is used to detect the diameter of the winding spring and control the moving speed of the adjustment wheel in real time based on the detection result.

[0008] As a further aspect of the present invention: the spindle replacement assembly includes a mounting plate, and each of the grooves in the circumferential direction of the mounting plate is provided with a screw through a bearing. Each screw has an adjusting component threadedly connected to its outer wall, and a locking rod is fixedly connected to the opposite side of each adjusting component.

[0009] As a further embodiment of the present invention: an insertion hole is provided in the middle of the outer surface of the mounting plate, the insertion hole is inserted into the winding spindle, and locking holes are arranged on the outer surface of the winding spindle near the mounting plate in the circumferential direction, the locking holes are inserted into the locking rods respectively.

[0010] As a further aspect of the present invention: the adjustment drive assembly includes a lead screw, a servo motor is mounted on one end of the lead screw, the servo motor is connected to the control module, a movable part is threadedly connected to the outer wall of the lead screw, a cylinder is mounted on the bottom of the movable part, and the output end of the cylinder is connected to the adjustment wheel.

[0011] As a further aspect of the present invention: a displacement sensor is installed on one side of the adjusting wheel, the displacement sensor is used to monitor the position of the adjusting wheel in real time, and the displacement sensor is connected to the control module.

[0012] As a further aspect of the present invention: the adaptive detection component includes a base, and both ends of the base are hinged with arc-shaped parts. One arc-shaped part is provided with a magnetic adsorption part at its upper end, and the other arc-shaped part is provided with a metal part at its upper end. The metal part and the magnetic adsorption part are magnetically attracted to each other, so that the two arc-shaped parts surround the outside of the winding spindle.

[0013] As a further aspect of the present invention: photoelectric sensors are symmetrically installed on the inner wall of the arc-shaped component, and the photoelectric sensors are connected to the control module.

[0014] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows:

[0015] 1. This invention enables the assembly and disassembly of the winding spindle by setting up a spindle replacement component. The operation only requires rotating the screw to lock and unlock. The multi-point radial locking design ensures the coaxiality and stability of the winding spindle at high speeds, which facilitates the processing of springs with different inner diameter specifications and enables rapid prototyping for multi-specification production.

[0016] 2. The controller of this invention controls the servo motor to drive the adjusting wheel to move axially along the winding spindle in real time according to the preset pitch parameters and the current winding spindle speed. This pushes the spring wire away from the previous turn by a fixed distance each time it is wound, thus achieving pitch adjustment. The photoelectric sensor can pass through after the spring is formed to detect the specifications of the wound spring in real time and automatically adjust the moving speed of the adjusting wheel along the winding spindle, achieving adaptive adjustment of the spring winding without stopping the machine, thereby improving production efficiency and product accuracy.

[0017] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from the practice of the invention.

[0024] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0025] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Please see the appendix Figure 1 - Appendix Figure 5 The present invention discloses a multi-specification spring winding forming and pitch adaptive adjustment device, including a base 1 and an external control module. A winding mechanism 2 is installed at one end of the base 1, and a feeding mechanism 4 is installed at the other end of the base 1 and located on the feeding side of the winding mechanism 2. A pitch adjustment mechanism 3 is installed above the winding mechanism 2.

[0027] In the first embodiment, the winding mechanism 2 includes a drive box 21, a spindle replacement assembly 22 is installed at the output end of the drive box 21, and a winding spindle 23 is detachably installed inside the spindle replacement assembly 22. The winding mechanism 2 is used to wind spring wire to form a spring.

[0028] Specifically, the spindle replacement assembly 22 includes a mounting plate 221. Each groove in the circumferential direction of the mounting plate 221 is provided with a screw 222 via a bearing. Each screw 222 has an adjusting member 223 threadedly connected to its outer wall. Each adjusting member 223 has a locking rod 224 fixedly connected to its opposite side. The mounting plate 221 has an insertion hole 225 in the middle of its outer surface. The insertion hole 225 is inserted into the winding spindle 23. The outer surface of the winding spindle 23 near the mounting plate 221 has locking holes 231 arranged in the circumferential direction. The locking holes 231 are correspondingly inserted into the locking rods 224.

[0029] In this embodiment, multiple screws 222 on the mounting plate 221 are driven to rotate, causing the adjusting component 223 to move radially, so that the locking rod 224 extends into or disengages from the locking hole 231, thereby facilitating the replacement of different specifications of the winding spindle 23 and realizing rapid prototyping for multi-specification production.

[0030] In embodiment 2, the pitch adjustment mechanism 3 includes an adjustment drive assembly 31, an adjustment wheel 32 is mounted at the bottom of the adjustment drive assembly 31, the adjustment wheel 32 acts on the spring wire to change the spring pitch, and the pitch adjustment mechanism 3 also includes an adaptive detection assembly 34, which is set at the other end of the winding spindle 23 and is used to detect the diameter of the winding spring and control the moving speed of the adjustment wheel 32 in real time according to the detection result.

[0031] Specifically, the adjustment drive assembly 31 includes a lead screw 311, a servo motor 312 is installed at one end of the lead screw 311, the servo motor 312 is connected to the control module, a movable part 313 is threaded to the outer wall of the lead screw 311, a cylinder 314 is installed at the bottom of the movable part 313, and the output end of the cylinder 314 is connected to the adjustment wheel 32.

[0032] In this embodiment, during winding, the control module drives the cylinder 314 so that the adjusting wheel 32 abuts against one end of the spring wire. Then, the servo motor 312 starts, causing the lead screw 311 to drive the movable part 313 to move and wind the spring wire into shape. The controller controls the servo motor 312 to drive the adjusting wheel 32 to move axially along the winding spindle 23 in real time according to the preset pitch parameters and the current speed of the winding spindle 23. This allows the spring wire to be pushed away from the previous turn by a fixed distance each time it is wound, thus achieving pitch adjustment.

[0033] Specifically, a displacement sensor 33 is installed on one side of the adjusting wheel 32. The displacement sensor 33 is used to monitor the position of the adjusting wheel 32 in real time and is connected to the control module.

[0034] Specifically, the adaptive detection component 34 includes a base 341, with arc-shaped parts 342 hinged at both ends of the base 341. One arc-shaped part 342 has a magnetic adsorption part 343 at its upper end, and the other arc-shaped part 342 has a metal part 344 at its upper end. The metal part 344 and the magnetic adsorption part 343 magnetically attract each other, so that the two arc-shaped parts 342 surround the outside of the winding spindle 23. Photoelectric sensors 345 are symmetrically installed on the inner wall of the arc-shaped parts 342, and the photoelectric sensors 345 are connected to the control module.

[0035] In this embodiment, the wound spring is removed by the operator and passed through the detection ring composed of the arc-shaped part 342. The photoelectric sensor 345 detects the position change of the outer edge of the spring in real time and continuously transmits the signal to the control module. The control module compares the real-time diameter with the preset diameter, and calculates the required axial movement speed of the adjusting wheel 32 according to the preset pitch parameters and the current rotation speed of the winding spindle 23, thus forming the required pitch.

[0036] Working principle:

[0037] First, select a winding spindle 23 with the corresponding diameter according to the inner diameter specification of the spring to be produced. Insert the winding spindle 23 into the insertion hole 225. By rotating the screw 222, the screw 222 drives the adjusting component 223 to move the locking rod 224 towards the axis, so that the locking rod 224 is inserted into the locking hole 231, thus completing the locking of the winding spindle 23.

[0038] The operator inputs the parameters of the target spring (diameter, pitch length, etc.) into the external control module (such as PLC), rotates the two arc-shaped parts 342 of the adaptive detection component 34 around the bottom to close, and the upper magnetic adsorption part 343 magnetically locks the metal part 344, so that the two arc-shaped parts 342 form a complete ring, surrounding the outside of the discharge end of the winding spindle 23.

[0039] The control module issues a command, and the feeding mechanism 4 starts to operate, continuously and stably feeding the spring wire toward the winding spindle 23. The spring wire is delivered to the upper surface of the winding spindle 23, and the control module drives the cylinder 314 to make the adjusting wheel 32 press one end of the spring wire. Then, the drive box 21 starts to drive the winding spindle 23 to rotate at the set speed. At the same time, the controller controls the servo motor 312 to drive the adjusting wheel 32 to move along the axial direction of the winding spindle 23 in real time according to the preset pitch parameters and the current speed of the winding spindle 23. This allows the spring wire to be pushed away from the previous turn by a fixed distance each time it is wound, thus realizing pitch adjustment.

[0040] The wound spring is removed by the operator and passed through the detection ring composed of the arc-shaped part 342. The photoelectric sensor 345 detects the position change of the outer edge of the spring in real time and continuously transmits the signal to the control module. The control module compares the real-time diameter with the preset diameter, calculates the required axial movement speed of the adjusting wheel 32 based on the preset pitch parameters and the current rotation speed of the winding spindle 23, and forms the required pitch. At this point, the entire workflow is completed.
