Description

Technical Field

[0001] The invention relates to an automatic centering structure. Background Art

[0002] During the production process of the cable, the cable core must be fixed in the center position to avoid shaking during the production process and causing damage. At present, in order to ensure that the cable core is in the center position during the production process, two sets of parallel guide rollers are usually used to overlap each other vertically to form a tic-tac-toe structure, and the two pairs of parallel guide rollers are adjusted in the two horizontal and vertical open grooves in the groove respectively. According to the outer diameter of the cable, the position of the four guide rollers is manually adjusted to ensure that the cable passes stably through the tic-tac-toe guide rollers. However, when passing cables of different outer diameters through the openings of the four guide rollers, it is necessary to loosen the screws on the four guide rollers, and then fix the nuts in turn after adjustment. The operation is cumbersome, time-consuming and labor-intensive, and the center position of the cable core cannot be guaranteed to remain unchanged during the adjustment of the four guide rollers. Especially in the extrusion process, the deviation of the center position can easily lead to eccentricity of the extrusion layer, resulting in product quality defects. Summary of the invention

[0003] The object of the present invention is to provide an automatic centering structure which is simple to operate, saves time and effort, and enables the central axis of the cable core to be at the same position when replacing cables with different outer diameters.

[0004] To achieve the above object, the present invention provides the following technical solution: an automatic centering structure, comprising:

[0005] Mounting seat;

[0006] an elastic member connected to the mounting seat; and

[0007] A clamping assembly connected to the elastic member and capable of applying a force to the elastic member under the action of an external force so as to cause the elastic member to deform;

[0008] Wherein, the clamping components are provided with at least two groups, and at least two groups of the clamping components form a clamping space to clamp and fix the target object;

[0009] Each group of the clamping components has a first clamping state and a second clamping state. When the clamping components are switched between the first clamping state and the second clamping state, the clamping components apply force to the elastic member to cause the elastic member to deform and thereby adjust the position of the clamping components relative to the target object, thereby ensuring that the central axis of the target object is always located at the same position.

[0010] Further, each group of the clamping components includes support rods arranged in parallel and clamping members sleeved on the support rods, the elastic member is sleeved on the support rods and connected to the clamping members, and the clamping members have a clamping surface;

[0011] When the clamping assembly is in the first clamping state, the horizontal central axes of the clamping surfaces of the two clamping members in each group do not overlap; when the clamping assembly is in the second clamping state, the horizontal central axes of the clamping surfaces of the two clamping members overlap.

[0012] Further, the clamping surface is an arc surface.

[0013] Further, the clamping assembly further includes a friction member disposed on the clamping member, and the friction member is disposed on at least a part of the clamping surface.

[0014] Further, the friction member is a protrusion.

[0015] Further, the friction member and the clamping member are integrally formed or separately provided.

[0016] Further, the clamping assembly further includes at least one bearing, and at least one of the bearings is installed on the end side of the clamping member.

[0017] Further, the clamping assembly further includes a buffer member, and the buffer member is disposed at one end of the clamping member away from the elastic member.

[0018] Further, the two clamping members of each group of clamping assemblies are disposed on the same side of the mounting seat.

[0019] Further, the two clamping members of each group of clamping assemblies are respectively disposed on both sides of the mounting seat.

[0020] The beneficial effects of the present invention are as follows: by providing an elastic member and at least two groups of clamping assemblies connected to the elastic member, at least two groups of clamping assemblies form a clamping space to clamp and fix the target object, and each group of clamping assemblies has a first clamping state and a second clamping state. When the clamping assembly is switched between the first clamping state and the second clamping state, only by applying a force to the elastic member through the clamping assembly, the elastic member is deformed to adjust the position of the clamping assembly relative to the target object, so that the central axis of the target object is always in the same position, and the operation is simple, time-saving and labor-saving, improving the production efficiency.

[0027] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the convenience of description, only parts related to the present invention rather than all structures are shown in the drawings. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0028] The terms "comprise" and "have" in the present invention and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0029] Referring to "embodiments" herein means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present invention. The phrase appears at various positions in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0030] Please refer to Figure 1 and Figure 3, the automatic centering structure shown in a preferred embodiment of the present invention is used to hold the target object to prevent the target object from shifting. In this embodiment, the target object 200 is a cable 200. In other embodiments, the target object can also be other things, and no specific limitation is made on the target object here. The automatic centering structure includes a mounting base 1 (not shown), an elastic member 3 connected to the mounting base 1, and a clamping assembly 2 connected to the elastic member 3. Among them, the clamping assembly 2 can apply a force to the elastic member 3 under an external force to cause the elastic member 3 to deform, and at least two groups of clamping assemblies 2 are provided. The at least two groups of clamping assemblies 2 form a clamping space (not labeled), and the cable 200 passes through the clamping space to be clamped and fixed. Please refer to Figure 2 and Figure 4 , each group of clamping assemblies 2 has an initial state, a first clamping state, and a second clamping state. When the clamping assembly 2 is switched between the initial state, the first clamping state, and the second clamping state, an external force is applied to the clamping assembly 2 to cause the elastic member 3 connected to the clamping assembly 2 to deform, thereby adjusting the position of the clamping assembly 2 relative to the cable 200, so that the central axis of the cable 200 is always located at the same position. It should be noted that the initial state is the state when the automatic centering structure does not clamp and fix the cable 200, the first clamping state is the state when the automatic centering structure clamps and fixes the cable 200 with a smaller outer diameter, and the second clamping state is the state when the automatic centering structure clamps and fixes the cable 200 with a larger outer diameter. In other embodiments, the state when the automatic centering structure clamps and fixes the cable 200 with a larger outer diameter can also be defined as the first clamping state, and the state when the automatic centering structure clamps and fixes the cable 200 with a smaller outer diameter can be defined as the second clamping state. When the clamping assembly 2 is in the initial state, the clamping assembly 2 abuts against the elastic member 3 or presses against the elastic member 3, and the length of the clamping assembly 2 is selected according to the size of the outer diameter of the cable 200, and no specific limitation is made here.

[0031] In order to prevent the cable 200 from shifting in the clamping space, in this embodiment, two sets of clamping components 2 are provided. Each set of clamping members 22 includes two parallel support rods 21 and a clamping member 22 sleeved on the support rod 21. Among them, each support rod 21 is connected to the mounting base 1 through a fixing base 4. In this embodiment, the automatic centering structure has four support rods 21 and four clamping members 22 respectively sleeved on the four support rods 21. The four clamping members 22 form the above-mentioned clamping space. When the cable 200 is inserted into the clamping space, the four clamping members 22 rotate along the four support rods 21 respectively, so that the cable 200 can pass through the clamping space more smoothly. In order to prevent the central axis of the cable 200 from shifting in the clamping space, in this embodiment, the two clamping members 22 of each set of clamping components 2 are arranged on the same side of the mounting base 1, and the central axes of the two sets of clamping components 2 are perpendicular to each other, that is, the two sets of clamping components 2 form a "well" shape. In other embodiments, the two clamping members 22 of the two sets of clamping components 2 can also be respectively arranged on the same side of the mounting base 1. At this time, the two sets of clamping components 2 form a "square" shape. Or, the two clamping members 22 of one set of clamping components 2 can be respectively arranged on both sides of the other set of clamping components 2, and the above-mentioned clamping space can also be formed to clamp and fix the cable 200. The positions of the four clamping members 22 are not specifically limited here, as long as the above effects are achieved.

[0032] Please refer to Figure 1 and Figure 5 , the clamping member 22 has a clamping surface 221. When an external force is applied to the clamping member 22, the cable 200 is inserted into the clamping space. The clamping surface 221 of the clamping member 22 contacts the outer surface of the cable 200 to clamp and fix the cable 200. Among them, the clamping surface 221 is set as an arc surface 221, and the arc surface 221 is a concave arc surface 221, so that when the automatic centering structure is used, the clamping component 2 can be switched between the first clamping state and the second clamping state, and the central axis of the cable 200 can always be on the same straight line without manually adjusting the position of the cable 200. In other embodiments, the arc surface 221 can also be set as a convex arc surface, and the conversion between the first clamping state and the second clamping state of the clamping member 22 can also be realized. It is not specifically limited here, as long as the conversion between the first clamping state and the second clamping state can be realized. Specifically, when the clamping component 2 is in the first clamping state, the central axes of the clamping surfaces 221 of the two clamping members 22 in each group do not overlap in the horizontal direction. When the clamping component 2 is in the second clamping state, the central axes of the clamping surfaces 221 of the two clamping members 22 overlap in the horizontal direction.

[0033] Please refer to Figure 5, in order to better fix the cable 200 and prevent the cable 200 from shifting, the clamping assembly 2 further includes a friction member 222 provided on the clamping member 22. The friction member 222 is provided on at least part of the clamping surface 221 to increase the frictional force between the outer surface of the cable 200 and the clamping surface 221. The friction member 222 and the clamping member 22 can be integrally formed or separately provided. In this embodiment, the friction member 222 is an annular protrusion 222 provided along the clamping surface 221 of the clamping member 22. In other embodiments, the friction member 222 can also be an annular groove provided along the clamping surface 221 of the clamping member 22, which is not specifically limited herein.

[0034] The clamping assembly 2 further includes at least one bearing (not shown). At least one shaft is installed on the end side of the clamping member 22 to improve the rotation accuracy of the clamping member 22. In this embodiment, two bearings are provided, and the two bearings are respectively provided at both ends of each clamping member 22 through connecting members.

[0035] Please refer to Figure 1 , the clamping assembly 2 further includes a buffer member 24, and the buffer member 24 is provided at one end of the clamping member 22 away from the elastic member 3. The purpose of providing the buffer member 24 is that when the clamping assembly 2 is converted from the second clamping state to the first conversion state, the clamping member 22 moves in the direction of the buffer member 24 under the action of the elastic member 3 to prevent the clamping member 22 from directly colliding with the fixed seat 4 and causing damage to the clamping member 22. In this embodiment, the buffer member 24 is an anti-collision nylon sleeve. Of course, in other embodiments, the buffer member 24 can also be other, which is not specifically limited herein.

[0036] In summary: By providing at least two sets of clamping members 22 and elastic members 3 connected to the clamping members 22, a clamping space is formed between at least two sets of clamping members 22 to clamp and fix the cable 200; since an arc-shaped surface is provided on each clamping member 22, when replacing cables 200 with different outer diameters in the clamping space, only an external force needs to be applied to the clamping member 22 to deform the elastic member 3 and then adjust the position of the clamping member 22 relative to the cable 200, and it can be ensured that the central axis of the cable 200 is always in the same position, with simple operation, time and labor saving, and improved production efficiency.

[0037] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0038] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
