Description

Technical Field

[0001] The utility model relates to the technical field of spring production, in particular to a spring coiling machine with a spring length adjustment function. Background Art

[0002] Springs are generally produced automatically using spring winding machines. During the production process, a feeding mechanism sends a certain length of wire material to a winding area for winding, and then the spring is cut to complete production. However, due to the feeding mechanism or the wire material, the feeding length is not very stable, resulting in inconsistent spring lengths. Since the length of the spring affects its elastic force, it is necessary to ensure that the length of the spring is within a reasonable range, where the length of the spring mainly depends on the feeding length of the wire feeding mechanism. In the prior art, the length is adjusted when the spring winding machine is initially produced. The linkage device in the spring winding machine is driven by rotating the handle to link with the feeding mechanism. After the feeding length is adjusted, production can be carried out. During production, the feeding length deviates due to the quality, temperature and effect of the wire feeding mechanism, resulting in a low spring yield and waste of materials. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a spring winding machine with a spring length adjustment function, which detects the spring length in real time through a sensor and performs forward and reverse rotation through a stepping motor to achieve real-time adjustment of the feed length, thereby solving the problem that the existing technology cannot adjust the feed length in time, resulting in low spring yield and waste of materials.

[0004] In order to solve the above technical problems, the utility model provides a technical solution: a spring coiling machine with a spring length adjustment function, comprising a spring coiling machine, an adjustment mechanism, a feeding mechanism and a rotating handle, wherein the feeding mechanism and the rotating handle are arranged on the spring coiling machine, and the rotating handle is linked to the feeding mechanism through a linkage device in the spring coiling machine, and the feeding length of the feeding mechanism is adjusted by rotating the handle, wherein the adjustment mechanism comprises a bracket and an ultrasonic sensor, and the ultrasonic sensor is supported by the bracket so that the ultrasonic sensor is located directly in front of the spring discharge port;

[0005] The rotating handle is replaced by a stepping motor, and the stepping motor is connected to the spring winding machine through a fixing bracket;

[0006] The ultrasonic sensor and the stepper motor are electrically connected to the controller.

[0007] Furthermore, the bracket is a multi-joint robotic arm.

[0008] Furthermore, the end of the multi-joint robotic arm is fixed to the spring coiling machine through a connecting block and bolts.

[0009] The beneficial effects of the utility model are:

[0010] 1. This application adds an ultrasonic sensor to the existing spring winding machine and replaces the rotary handle with a stepper motor to detect the length of the spring in real time. When the spring length is abnormal, the stepper motor is used to replace the rotary handle in the existing technology to rotate, thereby realizing real-time adjustment of the feed length, trying to keep the spring length within a reasonable range and reduce the defective rate of the spring.

[0011] 2. The ultrasonic sensor of the present application is fixed by a multi-joint robotic arm, which facilitates adjustment of the position of the ultrasonic sensor and is fixed on a spring winding machine, reducing structural complexity.

[0016] The following describes embodiments of the present invention in detail with reference to the accompanying drawings. Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the accompanying drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

Furthermore, the method embodiments may include additional steps or omit the steps shown. The scope of the present invention is not limited in this respect.

[0018] The names of the messages or information exchanged between multiple devices in the embodiments of the present invention are only used for illustrative purposes and are not used to limit the scope of these messages or information. Example 1

[0019] like Figure 1 As shown, a spring winding machine with a spring length adjustment function includes a spring winding machine A, an adjustment mechanism, a feeding mechanism B and a rotating handle. The feeding mechanism B and the rotating handle are arranged on the spring winding machine A. The rotating handle is linked with the feeding mechanism B through a linkage device in the spring winding machine A. The feeding length of the feeding mechanism B is adjusted by rotating the handle. The adjustment mechanism includes a bracket 1 and an ultrasonic sensor 2. The ultrasonic sensor 2 is supported by a fixing bracket 4 so that the ultrasonic sensor 2 is located directly in front of the spring discharge port; the rotating handle is replaced by a stepper motor 5, and the stepper motor 5 is connected to the spring winding machine A through a support base; the ultrasonic sensor 2 and the stepper motor 5 are electrically connected to the controller 3; the stepper motor 5 replaces the rotating handle, and when adjusting the feeding mechanism B, there is no need for manual operation of the rotating handle by personnel, and in conjunction with the ultrasonic Sensor 2 measures the length of the spring (the cutting position of the spring is relatively fixed with the position of the ultrasonic sensor 2, and the ultrasonic wave can measure the distance from the ultrasonic sensor 2 to the end of the spring, thereby obtaining the length of the spring). When the length of the spring is less than the set range, it means that the feed length is too short, and the stepper motor 5 is rotated to increase the feed length. When the length of the spring is greater than the set range, it means that the feed length is too long, and the stepper motor 5 is rotated in the opposite direction to reduce the feed length, so that the feed length reaches the appropriate length range. Among them, the prior art adjusts the feed length according to the rotation angle of the rotating handle. The present application replaces the rotation angle of the rotating handle in the prior art with the precise control of the rotation angle by the stepper motor 5, and then uses the control of the rotation angle by the stepper motor 5 to adjust the feed length. Example 2

[0020] like Figure 1 As shown, this embodiment is obtained by further describing the technical features such as the bracket 1 on the basis of the embodiment one. The remaining technical features are the same as those of the embodiment one, and the similarities are not repeated here. Among them, the difference between this embodiment and the embodiment one is that: the bracket 1 is a multi-joint robotic arm; the end of the multi-joint robotic arm is fixed to the spring winding machine A by a connecting block and bolts.

[0021] In this embodiment, the ultrasonic sensor 2 is fixed by a multi-joint robotic arm, which facilitates adjustment of the position of the ultrasonic sensor 2 and is fixed on the spring coiling machine A, reducing structural complexity.

[0022] The ultrasonic sensor 2 and the controller 3 may be existing mature products, and the specific manufacturer and model are not limited here.

[0023] The use process of the technical solution formed by the above embodiments is as follows: the universal robotic arm 1 is fixed on the spring winding machine A. When the spring is wound but not cut, the ultrasonic sensor 2 detects the distance between it and the spring and sends the distance in the form of an electrical signal to the controller 3. After processing, the controller 3 obtains the length of the spring (the length from the ultrasonic sensor 2 to the spring cutting position minus the obtained distance), and compares the length of the spring with a preset threshold range. When the length of the spring is less than the set range, it means that the feed length is too short, and the feed length is increased by rotating the stepper motor 5. When the length of the spring is greater than the set range, it means that the feed length is too long, and the feed length is reduced by rotating the stepper motor 5 in the opposite direction, so that the feed length reaches the appropriate length range, thereby realizing real-time detection and adjustment of the spring.

[0024] Note that the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are readily apparent to those skilled in the art without departing from the scope of protection of the present invention. Therefore, while the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the appended claims.
