Description

Technical Field

[0001] This application relates to the field of automation equipment technology, and more specifically, to a ring spring locking and positioning device. Background Technology

[0002] Currently, the winding of circular springs into fixed-size circles is done manually, which is extremely inefficient. The difficulty in automating the winding of circular springs lies in the fact that the springs have a large elastic force, making it impossible to effectively fix and support them. Excessive support force can easily cause them to bend and deform, while insufficient support force will also affect the roundness of the formed product. The formed product is not perfectly round and requires subsequent reshaping. Secondly, after the spring is wound into a circle, the driving force required increases as the diameter decreases, and this change is not linear, requiring complex control algorithms for control.

[0003] Therefore, those skilled in the art need to improve existing positioning devices to enhance the roundness of the formed product. Summary of the Invention

[0004] The main purpose of this application is to provide a circular spring locking and positioning device to ensure that the formed product is perfectly circular.

[0005] To achieve the above objectives, in a first aspect, this application provides a ring spring locking and positioning device, including a base, a cylindrical core fixedly disposed on the base, and a first abutting component, a second abutting component, and a third abutting component disposed on the outer circumference of the core. The first abutting component includes a first abutting part slidably disposed on the base and a first driving mechanism for driving the first abutting part to slide. The first abutting part is tangentially disposed to the outer circumference of the workpiece. The second abutting component includes a second abutting part slidably disposed on the base and a second driving mechanism for driving the second abutting part to slide. The second abutting part has a first arc-shaped contact surface, and the first contact surface has a plurality of serrated structures with radii of curvature. The third abutting component includes a third abutting part slidably disposed on the base and a third driving mechanism for driving the third abutting part to slide. The third abutting part has a second arc-shaped contact surface, and the second contact surface has a plurality of serrated structures with radii of curvature.

[0006] A further improvement is that a pressing component is slidably disposed on the first abutment portion, the pressing component including a pressing part slidably disposed with the first abutment portion and a fourth driving mechanism for driving the pressing part to slide.

[0007] A further improvement is that the clamping component, the second abutting component, and the third abutting component are arranged in an equilateral triangle.

[0008] A further improvement is that a limiting structure is provided between the pressing part and the first abutting part.

[0009] A further improvement is that a first sliding frame is slidably disposed on the base, the second driving mechanism is slidably disposed on the first sliding frame, and a first locking structure is provided between the first sliding frame and the base.

[0010] A further improvement is that a second sliding frame is slidably disposed on the base, the core seat is fixedly disposed on the second sliding frame, and a fifth driving mechanism is disposed between the second sliding frame and the base.

[0011] A further improvement is that a first rotating frame is rotatably mounted on the base, the third driving mechanism is fixedly mounted on the first rotating frame, and a second locking mechanism is provided between the base and the first rotating frame to lock the two in at least two working positions.

[0012] A further improvement is that the first drive mechanism, the second drive mechanism, the third drive mechanism, and the fourth drive mechanism are all cylinders.

[0013] A further improvement is that the fifth drive mechanism includes an adjusting screw rotatably mounted on the base and an adjusting sleeve fixedly mounted on the bottom of the second sliding frame and cooperating with the adjusting screw.

[0014] A further improvement is that a guide structure is provided between the first rotating frame and the base.

[0015] The circular ring spring locking and positioning device provided by this invention has the following advantages compared with the prior art: by setting three abutment components, the first abutment component is used for positioning, and the distance between the first abutment component and the core seat determines the diameter of the formed ring. The second and third abutment components have a sawtooth structure with multiple radii of curvature on their contact surfaces. Thus, during the forming process, the product can adapt to different radii of curvature as the product diameter changes, ensuring that the product always adapts to the appropriate circumferential surface during the forming process, thus ensuring the roundness of the formed ring.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] It should be noted that the terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be used interchangeably where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0020] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0021] In addition, the term "multiple" should mean two or more.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present application will now be described in detail with reference to the embodiments.

[0023] like Figures 1-3As shown, a ring spring locking and positioning device includes a base 1, a cylindrical core seat 13 fixedly disposed on the base 1, a first abutting component, a second abutting component, and a third abutting component disposed on the outer circumference of the core seat 13. The first abutting component includes a first abutting part 2 slidably disposed on the base 1 and a first driving mechanism 3 for driving the first abutting part 2 to slide. The first abutting part 2 is tangentially disposed to the outer circumference of the workpiece. The second abutting component includes a second abutting part 4 slidably disposed on the base 1 and a second driving mechanism 5 for driving the second abutting part 4 to slide. The second abutting part 4 has a first contact surface in the shape of an arc and a serrated structure with multiple radii of curvature on the first contact surface. The third abutting component includes a third abutting part 6 slidably disposed on the base 1 and a third driving mechanism 7 for driving the third abutting part 6 to slide. The third abutting part 6 has a second contact surface in the shape of an arc and a serrated structure with multiple radii of curvature on the second contact surface.

[0024] It should be noted that the serrated structures on the first and second contact surfaces are symmetrically arranged, and each serration has a different radius of curvature. As the workpiece diameter changes during the automatic winding process, it ensures that there is always an arc surface on the first and second contact surfaces to match it, thus ensuring the roundness of the formed product and the quality of the product.

[0025] To prevent the spring sheet from warping during the winding process, a pressing component is slidably provided on the first abutment 2. The pressing component includes a pressing part 8 slidably disposed with the first abutment 2 and a fourth driving mechanism 9 for driving the pressing part 8 to slide. To ensure the accuracy of adjustment, a limiting structure is provided between the pressing part 8 and the first abutment 2. The limiting structure includes a dovetail groove disposed on the first abutment 2 and dovetail sliders disposed on both sides of the pressing part 8 that cooperate with the dovetail groove.

[0026] To improve the stability of product processing, the clamping component, the second abutting component, and the third abutting component are arranged in an equilateral triangle.

[0027] To enable the processing of different product models, a first sliding frame 10 is slidably mounted on the base 1, and a second driving mechanism 5 is slidably mounted on the first sliding frame 10. A first locking structure is provided between the first sliding frame 10 and the base 1. The first locking structure includes a slide rail fixedly mounted on the base 1 and a sliding part fixedly mounted on the bottom of the first sliding frame 10 and cooperating with the slide rail. The slide rail and the sliding part are fixed together by fasteners. Multiple locking holes are provided on the slide rail to cooperate with the fasteners, thereby achieving locking at different positions. A second sliding frame 5 is slidably mounted on the base 1. The core seat 13 is fixedly mounted on the second sliding frame 11. A fifth driving mechanism is provided between the second sliding frame 11 and the base 1. The fifth driving mechanism includes an adjusting screw rotatably mounted on the base 1 and an adjusting sleeve fixedly mounted on the bottom of the second sliding frame 11 and cooperating with the adjusting screw. For ease of operation, an operating handle is fixedly mounted at the end of the adjusting screw. By rotating the operating handle, the adjusting screw is driven to rotate, thereby realizing the sliding adjustment of the core seat 13. Of course, the core seat 13 can be detached and connected to the second sliding frame 11 to match the processing of different models of products.

[0028] Similarly, to accommodate the processing of different product models, a first rotating frame 12 is rotatably mounted on the base 1, and the third driving mechanism is fixedly mounted on the first rotating frame 12. A second locking mechanism is provided between the base 1 and the first rotating frame 12 to lock them in at least two working positions. The locking structure is not the design focus of this application. Multiple positioning holes can be opened on the rotating frame, and the first rotating frame 12 can be fixed to the base 1 by the cooperation of the positioning element and the positioning hole. In order to ensure the accuracy of the rotation of the first rotating frame 12 and the stability of the entire equipment, a guide structure is provided between the first rotating frame 12 and the base 1. The guide structure can be an arc-shaped guide groove opened on the first rotating frame 12, and a positioning pin that cooperates with the arc-shaped guide groove is fixedly mounted on the base 1.

[0029] In this embodiment, preferably, the first drive mechanism 3, the second drive mechanism 5, the third drive mechanism 7 and the fourth drive mechanism 9 are all cylinders. Of course, electric push rods and other similar devices can also be used.
