Description

Technical Field

[0001] This utility model relates to the field of wheel rim production technology, and in particular to a machine-pressed limiting structure for wheel rim production. Background Technology

[0002] The wheel rim, also known as the wheel hub, is one of the core components of a car wheel. It has a ring-shaped structure and its main function is to mount and securely support the tire around the wheel. It also connects with the wheel spokes and works in tandem to form a complete wheel assembly, providing fundamental support and serving as a crucial carrier for power transmission during vehicle movement.

[0003] A search revealed Chinese patent CN221020680U, which discloses a machine-pressed limiting structure for wheel rim production, relating to the field of automotive processing and manufacturing technology. The structure includes: an upper ball bearing, an upper rail, a lower ball bearing, a lower rail, a support column, and a bushing. Both the upper and lower ball bearings are semi-cylindrical. The upper rail is fixedly connected above the upper ball bearing, and the lower rail is fixedly connected below the lower ball bearing. The lower end face of the upper ball bearing corresponds to the upper end face of the lower ball bearing. A support column is symmetrically arranged on the lower end face of the upper ball bearing and is fixedly connected to the upper ball bearing. A bushing is symmetrically arranged on the upper end face of the lower ball bearing and is fixedly connected to the lower ball bearing. The support column is fitted inside the bushing, and a locking element is provided on the outside of the bushing. This design solves the problems of high costs due to excessive parts and high labor costs caused by complex operation requiring operators with certain technical skills and professional knowledge.

[0004] The aforementioned device requires manual positioning of the wheel rim and lacks a working environment isolation device. Manual positioning relies on manual adjustment to fix the wheel rim, which is not only cumbersome and time-consuming, but also requires repeated operation on each wheel rim individually in mass production, greatly increasing the labor intensity and slowing down the production pace. Furthermore, it is difficult to accurately control the positioning force manually, which can easily lead to problems such as the positioning being too loose, causing the wheel rim to shift or wobble during processing, or the positioning being too tight, damaging the inner wall of the wheel rim, affecting the processing accuracy and the yield of finished products. On the other hand, the lack of an environmental isolation device makes it easy for metal shavings generated during processing to fly around, which may cut the operators and pollute the processing environment. Utility Model Content

[0005] The purpose of this utility model is to provide a machine-pressed limiting structure for wheel rim production, which can solve the problems of the above-mentioned devices requiring manual limiting of the wheel rim and lacking a working environment isolation device. Manual limiting relies on manual adjustment and fixing of the wheel rim, which is not only cumbersome and time-consuming, but also requires repeated operation on each wheel rim one by one in batch production, which greatly increases the labor intensity and slows down the production pace. Moreover, it is difficult to accurately control the limiting force when applying force manually, which can easily lead to problems such as the limiting being too loose, causing the wheel rim to shift or shake during processing, or the limiting being too tight, damaging the inner wall of the wheel rim, affecting the wheel rim processing accuracy and the finished product qualification rate. On the other hand, the lack of an environmental isolation device makes it easy for metal shavings generated during processing to fly, which may scratch the operators and pollute the processing environment.

The connector drives multiple top plates to move outward, thereby providing inward support and limiting of the wheel rim. A shielding frame is disposed on one side of the mounting bracket; A support member is disposed on one side of the shielding frame, and the support member is used to drive the shielding frame to move laterally on one side of the mounting frame.

[0007] In one preferred embodiment, the connecting rod is fixedly disposed on one side of the mounting plate; A push plate is slidably disposed on the outside of the connecting rod, and the push plate moves laterally on the outside of the connecting rod; The first support arm is rotatably mounted on the inner side of the end of the push plate; A connecting block is rotatably disposed on the outer side of the end of the first support arm away from the push plate, and one side of the connecting block is connected to one side of the top plate; A sleeve is fixedly disposed on the outer side of the end of the connecting rod away from the mounting plate; The second connecting arm is rotatably disposed on the inner side of the end of the sleeve, and the outer side of one end of the second connecting arm is rotatably connected to the inner side of one end of the connecting block; The third connecting arm is rotatably disposed on the inner side of the end of the sleeve, and the outer side of one end of the third connecting arm is rotatably connected to the inner side of one end of the connecting block.

[0008] In a preferred embodiment, a first telescopic rod is mounted on one side of the mounting plate, and the outer side of the output end of the first telescopic rod is connected to one side of the push plate.

[0009] In a preferred embodiment, the outer side of the top plate is provided with an arc-shaped structure for fitting the inner side of the wheel rim.

[0010] Its specific function is as follows: with the support of the second and third connecting arms, the top plate is pushed outward to expand, and the arc-shaped structure on one side of the top plate forms a stable support for the inner side of the rim, so as to achieve precise positioning.

[0011] In a preferred embodiment, a first slide rail is installed on one side of the mounting frame, and the mounting plate is slidably connected to the mounting frame via the first slide rail; Top arms are rotatably mounted on the outer sides of both ends of the mounting plate; The slider is rotatably mounted on the inner side of the end of the top arm away from the mounting plate, and the outer side of the slider is connected to the inner side of the bottom end of the shielding frame.

It efficiently adapts to wheel rim production needs. After placing the wheel rim on the outside of the top plate, activating the first telescopic rod links the push plate, first support arm, and other components. Supported by the second and third connecting arms, the top plate expands outwards. The arc-shaped structure on one side of the top plate provides stable support to the inside of the wheel rim, achieving precise positioning and ensuring stable rim positioning during processing. Simultaneously, the second telescopic rod drives the mounting plate to slide vertically on the first slide rail, which in turn links the top arm and slider to move the two shielding frames inwards. This not only shields the wheel rim outside the top plate to isolate the processing environment and prevent external interference or waste splashing, but also allows fallen debris to fall directly into the collection box for centralized collection, reducing manual cleaning workload. Overall, it balances positioning stability, environmental protection, and convenient waste disposal, improving wheel rim production efficiency and processing standardization.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] Please see Figure 1 - Figure 4 This embodiment provides a machine-pressed limiting structure for rim production that can stably support the rim. The specific idea is as follows: A machine-pressed limiting structure for wheel rim production includes a mounting bracket 1, and the machine-pressed limiting structure for wheel rim production also includes a mounting plate 201 and a connector.

[0021] Among them, the top outer side of the mounting frame 1 is provided with a top plate 2 that plays a supporting role. It is a component that directly contacts the inner wall of the wheel rim. A mounting plate 201 that plays a mounting role is movably provided on one side of the mounting frame 1. The mounting plate 201 can move vertically along one side of the mounting frame 1. A connector is provided on one side of the mounting plate 201, which can drive multiple top plates 2 to move synchronously outward.

[0022] As examples, in this embodiment, the connector includes a connecting rod 202 and a push plate 203.

[0023] Among them, a connecting rod 202 that serves as a connecting element is fixedly connected to one side of the mounting plate 201, and a push plate 203 that serves as a connecting element is slidably connected to its outer side. The push plate 203 can move laterally outside the connecting rod 202. The inner side of the end of the push plate 203 is rotatably connected to a first support arm 204 that provides support. The outer side of the end of the first support arm 204 away from the push plate 203 is rotatably connected to a connecting block 205 that provides connection. One side of the connecting block 205 is fixedly connected to one side of the top plate 2. The lateral movement of the push plate 203 drives the first support arm 204 to rotate, thereby driving the connecting block 205 to move in conjunction with the top plate 2. Meanwhile, a sleeve 206 that serves as a connection is fixedly connected to the outer side of the end of the connecting rod 202 away from the mounting plate 201. The inner side of the end of the sleeve 206 is rotatably connected to a second connecting arm 207 and a third connecting arm 208 that serve as a support. The outer side of one end of both arms is rotatably connected to the inner side of one end of the connecting block 205. Through the coordinated rotation of multiple sets of connecting arms, stable support is provided for the movement of the top plate 2. In addition, a first telescopic rod 209 that serves as a drive is installed on one side of the mounting plate 201. The outer side of its output end is connected to one side of the push plate 203. The telescopic action of the first telescopic rod 209 provides power for the lateral movement of the push plate 203.

[0024] It should be noted that the outer side of the top plate 2 adopts an arc-shaped structure design. This arc-shaped structure fits into the inner contour of the rim. When the connecting parts drive multiple top plates 2 to move outward, the arc-shaped surface can form a large-area contact with the inner wall of the rim, so that the supporting force is evenly distributed and the accuracy of the rim machine pressing is ensured. Example 2

[0025] Please see Figure 1 - Figure 4This embodiment provides a machine-pressed limiting structure for rim production that facilitates shielding the processing environment. The specific concept is as follows: A machine-pressed limiting structure for wheel rim production includes a mounting frame 1, and the machine-pressed limiting structure for wheel rim production also includes a shielding frame 3 and a support member.

[0026] The mounting frame 1 has a shielding frame 3 on one side, which serves as a protective structure during the rim pressing process. The shielding frame 3 has a support on one side, which can drive the shielding frame 3 to move laterally on one side of the mounting frame 1.

[0027] As examples, in this embodiment, the support includes a first slide rail 301 and a top arm 302.

[0028] The mounting bracket 1 has a first slide rail 301 installed on one side for connecting. The mounting plate 201 is slidably connected to the mounting bracket 1 through the first slide rail 301. With the guidance of the first slide rail 301, the mounting plate 201 is ensured to move stably and vertically along a fixed trajectory. The mounting plate 201 has a top arm 302 rotatably connected to the outer sides of both ends, which plays a linkage role. The top arm 302 is rotatably connected to the inner side of the end away from the mounting plate 201, which plays a connecting role. The outer side of the slider 303 is fixedly connected to the inner side of the bottom end of the shielding frame 3. The movement linkage between the mounting plate 201 and the shielding frame 3 can be realized by rotating the top arm 302. Meanwhile, a second slide rail 304 is installed on the inner side of the bottom end of the mounting frame 1 for connecting purposes. The slider 303 is slidably connected to the inner side of the bottom end of the mounting frame 1 through the second slide rail 304, providing stable guidance for the movement of the slider 303. A second telescopic rod 305 for driving purposes is installed on the inner side of the top end of the mounting frame 1, and its output end is connected to the outer side of the top end of the mounting plate 201. The extension and retraction of the second telescopic rod 305 drives the mounting plate 201 to move vertically along the first slide rail 301, and then drives the slider 303 to slide along the second slide rail 304 through the top arm 302, ultimately realizing the lateral movement of the shielding frame 3.

[0029] In addition, a collection box 306 is fixedly connected to the inner side of the bottom of the shielding frame 3. During the wheel rim pressing process, the generated debris and impurities can slide down the inner wall of the shielding frame 3 into the collection box 306. The collection box 306 realizes the centralized collection of waste materials and avoids the waste materials from scattering and polluting the working environment.

[0030] Working principle: When using the device, the user can place the rim on the outside of the top plate 2. At this time, the user can activate the first telescopic rod 209. The first telescopic rod 209 pushes the push plate 203 to slide on the outside of the connecting rod 202. Then, the push plate 203 pushes multiple first support arms 204 to rotate. While the first support arms 204 are rotating, under the support of the second connecting arm 207 and the third connecting arm 208, the top plate 2 is driven to expand outward. Then, the arc structure on one side of the top plate 2 supports the inner side of the rim, thereby achieving stable positioning. At the same time, the second telescopic rod 305 can drive the mounting plate 201 to slide vertically upward on the first slide rail 301. While the mounting plate 201 is sliding, it will pull the sliders 303 on both sides to move inward through the top arm 302. Then, it will drive the two shielding frames 3 to move inward. Then, the shielding frames 3 can shield the rim on the outside of the top plate 2, isolate the processing environment, and the falling debris will fall into the inner side of the collection box 306 for collection.

[0031] This machine-pressed limiting structure for wheel rim production offers significant advantages in wheel rim limiting and fixing, processing environment protection, and debris handling. It efficiently adapts to wheel rim production needs. After placing the wheel rim on the outside of the top plate 2, activating the first telescopic rod 209 links the push plate 203, the first support arm 204, and other components. Supported by the second connecting arm 207 and the third connecting arm 208, the top plate 2 expands outward. The arc-shaped structure on one side of the top plate 2 provides stable support to the inner side of the wheel rim, achieving precise limiting and ensuring positional stability during wheel rim processing. Simultaneously… The second telescopic rod 305 can drive the mounting plate 201 to slide vertically on the first slide rail 301, thereby linking the top arm 302 and the slider 303 to move the two shielding frames 3 inward. This can shield the outer rim of the top plate 2 to isolate the processing environment and avoid external interference or the splashing of processing waste. It can also allow the falling debris to fall directly into the inner side of the collection box 306 for centralized collection, reducing the burden of manual cleaning. Overall, it takes into account the stability of the limit position, environmental protection and the convenience of waste disposal, and improves the production efficiency and processing standardization of the rim.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
