Description

Technical Field

[0001] This utility model relates to the field of automobile wheel hub manufacturing technology, and in particular to a pressure testing machine for automobile wheel hubs. Background Technology

[0002] Automotive wheel hubs are key components of a vehicle's driving system, and their performance directly affects the vehicle's safety, stability, and comfort. With the rapid development of the automotive industry, especially the widespread adoption of new energy vehicles and intelligent vehicles, the quality requirements for wheel hubs are increasingly stringent. Stress testing, as an important part of wheel hub quality control, can effectively detect the strength and durability of wheel hubs under extreme conditions.

[0003] In the prior art, since wheel hub bearings are usually circular, this geometric characteristic makes them prone to rolling or sliding when subjected to external pressure. During pressure testing, wheel hub bearings may shift due to uneven force or unstable fixing, resulting in distorted test data. Utility Model Content

[0004] This utility model mainly provides a pressure testing machine for automobile wheel hubs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pressure testing machine for automobile wheel hubs, comprising a testing machine body, a transmission mechanism on the testing machine body, a pressure plate at the bottom of the transmission mechanism, a testing platform on the outer wall of the testing machine body below the pressure plate, a limiting component inside the testing platform, the testing platform limiting the wheel hub through the limiting component, and a control panel at the front end of the transmission mechanism.

[0006] Preferably, the limiting component includes a guide groove formed on the surface of the test platform below the pressure plate. A motor is provided at the front end of the test platform, and a bidirectional lead screw is provided at the output end of the motor. The bidirectional lead screw rotates in the guide groove. Two sets of transmission blocks are threaded onto the bidirectional lead screw. Each transmission block has a fixed seat at its top. Each fixed seat has a clamping groove on its side facing the test platform. A wheel hub is placed in the middle of the clamping groove. Two sets of sliding grooves are provided on the side of the clamping groove facing the wheel hub. A first spring is provided on the inner wall of each sliding groove. A limiting plate is fixedly connected to the other end of each first spring. The limiting plate slides linearly in the clamping groove.

[0007] Preferably, anti-slip textures are provided on the corresponding side surfaces of both sets of clamping grooves.

[0008] Preferably, the input end of the motor is electrically connected to the controller via a wire, and the top of the test bench is provided with a groove for storing the controller.

[0009] Preferably, the transmission mechanism is provided with a protective component to protect the control panel. The protective component includes two sets of fixed blocks on the surface of the transmission mechanism above the control panel. A rotating component rotates inside the fixed block. A socket slides at the bottom of the rotating component. A protective cover is provided at the bottom of the socket. A spring groove is provided on one side of the rotating component. A second spring is provided on the inner wall of the spring groove. A positioning post is fixedly connected to the other end of the second spring. A positioning groove is provided on the inner wall of the socket corresponding to the outer end surface of the positioning post.

[0010] Preferably, the portion of the rotating component inserted into the socket is rectangular in shape, and the top surface of the socket has a countersunk hole that matches the rotating component.

[0011] Preferably, the outer end surface of the positioning post is provided with a soft pad, and the soft pad is an anti-slip soft pad.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, a motor drives a bidirectional lead screw to rotate in a guide groove, and two sets of transmission blocks move on the bidirectional lead screw and converge towards the center of the bidirectional lead screw, thereby clamping the hub with two sets of clamping grooves. Then, the restoring force of the first spring pushes the limiting plate to slide in the slide groove, and the two sets of limiting plates limit the two sides of the hub, thereby achieving the purpose of fixing the hub. This makes it less likely for the hub to shift or roll during the pressure test, thus improving the accuracy of the test data.

[0014] 2. In this utility model, by fitting the socket onto the rotating part and aligning the positioning post with the positioning groove, the restoring force of the second spring is used to push the positioning post to slide back in the spring groove and pass through the positioning groove, thereby achieving the purpose of replacing the protective cover and preventing damage to the protective cover, which would otherwise prevent the protective cover from failing to protect the control panel.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a pressure testing machine for automobile wheel hubs, including a testing machine body 1, a transmission mechanism 2 on the testing machine body 1, a pressure plate 3 at the bottom of the transmission mechanism 2, a testing platform 4 on the outer wall of the testing machine body 1 below the pressure plate 3, a limiting component 5 inside the testing platform 4, and the testing platform 4 limiting the wheel hub through the limiting component 5. A control panel 7 is provided at the front end of the transmission mechanism 2.

[0023] like Figure 2 and 3 As shown, the limiting component 5 includes a guide groove 51 formed on the surface of the test platform 4 below the pressure plate 3. A motor 52 is provided at the front end of the test platform 4. A bidirectional lead screw 53 is provided at the output end of the motor 52. The bidirectional lead screw 53 rotates in the guide groove 51. Two sets of transmission blocks 54 are threadedly connected to the bidirectional lead screw 53. A fixed seat 55 is provided on the top of each transmission block 54. A clamping groove 56 is provided on the side surface of the fixed seat 55 facing the test platform 4. A hub is placed in the middle of the clamping groove 56. Two sets of sliding grooves 57 are provided on the side surface of the clamping groove 56 facing the hub. A first spring 58 is provided on the inner wall of each sliding groove 57. A limiting plate 59 is fixedly connected to the other end of each first spring 58. The limiting plate 59 slides linearly in the clamping groove 56.

[0024] The motor 52 drives the bidirectional lead screw 53 to rotate in the guide groove 51, and causes the two sets of transmission blocks 54 to move on the bidirectional lead screw 53 and converge towards the middle of the bidirectional lead screw 53, thereby clamping the wheel hub with the two sets of clamping grooves 56. Then, the restoring force of the first spring 58 pushes the limiting plate 59 to slide in the slide groove 57, and the two sets of limiting plates 59 limit the two sides of the wheel hub, thereby achieving the purpose of fixing the wheel hub. This makes it less likely for the wheel hub to shift or roll during the pressure test, thus improving the accuracy of the test data.

[0025] like Figure 3 As shown, anti-slip textures are provided on the corresponding side surfaces of the two sets of clamping grooves 56, which can improve the friction when the wheel hub contacts the clamping groove 56, thereby ensuring the stability of the clamping groove 56 when clamping the wheel hub and preventing the wheel hub from shifting.

[0026] like Figure 2 As shown, the input terminal of motor 52 is electrically connected to the controller via a wire. The top of the test bench 4 is provided with a groove for storing the controller, which makes it convenient for staff to operate motor 52, thereby improving the convenience of using motor 52 and preventing the controller from falling to the ground and being damaged.

[0027] like Figure 3 and Figure 4 As shown, a protective component 6 is provided on the outside of the transmission mechanism 2. The protective component 6 protects the control panel 7. The protective component 6 includes two sets of fixing blocks 61 set on the surface of the transmission mechanism 2 above the control panel 7. A rotating part 62 rotates inside the fixing block 61. A socket 63 slides at the bottom of the rotating part 62. A protective cover 64 is provided at the bottom of the socket 63. A spring groove 65 is opened on one side of the rotating part 62. A second spring 66 is provided on the inner wall of the spring groove 65. A positioning post 67 is fixedly connected to the other end of the second spring 66. A positioning groove 68 is opened on the inner wall of the socket 63 corresponding to the outer end surface of the positioning post 67.

[0028] By fitting the socket 63 onto the rotating member 62 and aligning the positioning pin 67 with the positioning groove 68, and then using the restoring force of the second spring 66 to push the positioning pin 67 to return to its original position within the spring groove 65 and allow the positioning pin 67 to pass through the positioning groove 68, the purpose of replacing the protective cover 64 is achieved, preventing damage to the protective cover 64 and ensuring that the protective cover 64 can no longer protect the control panel 7.

[0029] like Figure 4 As shown, the part of the rotating component 62 that inserts into the socket 63 is rectangular in shape. The top surface of the socket 63 has a countersunk hole that matches the rotating component 62, which allows the socket 63 to slide stably in a straight line on the rotating component 62, thereby achieving the purpose of positioning the positioning post 67 and the positioning groove 68, so as to facilitate the installation of the protective cover 64 by the staff.

[0030] like Figure 4 As shown, a soft pad is provided on the outer surface of the positioning post 67, and the soft pad is a non-slip soft pad, which can improve the comfort of the operator pressing the positioning post 67 into the spring groove 65 by hand and prevent the hand from slipping when pressing the positioning post 67.

[0031] The usage and working principle of this device are as follows: When in use, first place the wheel hub in the two sets of clamping slots 56. Then, start the motor 52 through the controller. The motor 52 drives the bidirectional lead screw 53 to rotate in the guide slot 51, and causes the two sets of transmission blocks 54 to move on the bidirectional lead screw 53 and converge towards the middle of the bidirectional lead screw 53, so that the two sets of clamping slots 56 clamp the wheel hub. Then, the restoring force of the first spring 58 pushes the limiting plate 59 to slide in the slide groove 57, and causes the two sets of limiting plates 59 to limit the two sides of the wheel hub. Then, the transmission mechanism 2 drives the pressure plate 3 to perform a pressure test on the wheel hub.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the 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 this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
