Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment for steel rim production, and in particular to a testing device for bicycle steel rim production. Background Technology

[0002] Bicycles are a common means of transportation and sports equipment, and are widely used around the world. As one of the key components of a bicycle, the quality of the bicycle rim directly affects the overall performance, safety, and riding experience of the bicycle. The production process of bicycle rims involves multiple complex processes, such as the selection, cutting, forming, welding, and surface treatment of steel. Each process may introduce various quality problems, so it is essential to conduct comprehensive and accurate testing of the rims.

[0003] The roundness of the rim is an important indicator. An out-of-round rim will cause uneven stress on the tire, accelerate tire wear, and affect riding comfort and handling. Existing testing methods usually involve fitting the rim onto a regular ring and then rotating it to observe whether the ring and the inner side of the rim are in complete contact. However, this method cannot accurately and in real time detect minute deviations in the roundness of the rim. Therefore, the above problems need to be addressed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a testing device for bicycle rim production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a testing device for bicycle rim production, comprising a base, a first support rod and a second support rod installed on the upper end of the base, a first sliding groove being opened laterally at the front end of the base, and a positioning mechanism being installed on the top surface of the base, a second sliding groove being opened vertically at the front end of the first support rod, and a testing mechanism being slidably installed on both the first sliding groove and the second sliding groove.

[0006] Preferably, positioning rollers are installed on the inner sides of the upper ends of the first and second support rods, and second motors are installed on the outer sides of the upper ends of the first and second support rods, with the output end of the second motors connected to the rotating shaft of the positioning rollers.

[0007] Preferably, the positioning mechanism includes a first motor mounted on one side of the top surface of the base, and the first motor is equipped with a lead screw via a coupling.

[0008] Preferably, the bottom end of the first support rod is fixedly connected to the top surface of the base, and the lower part of the first support rod has a guide hole that passes through the lead screw.

[0009] Preferably, the bottom end of the second support rod slides against the top surface of the base, and the lower part of the second support rod is provided with a threaded hole that mates with the lead screw.

[0010] Preferably, the detection mechanism includes an I-shaped slider that is slidably installed in a first slide groove and a second slide groove. A telescopic rod is hinged to the top surface of the slider. A connecting block is rotatably installed on the telescopic rod. A pressure sensor is installed at the other end of the connecting block. The output end of the pressure sensor is fixedly connected to the connecting rod. A detection wheel is installed at the other end of the connecting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of the moving mechanism and the positioning roller, facilitates the installation of the steel ring between two positioning rollers, and drives it to rotate through the second motor. Then, by abutting the detection wheel against the inner side of the steel ring, when there is a depression inside the steel ring, the detection wheel will shake irregularly, causing the vibration sensor to detect the vibration. It can accurately detect whether there is a deviation in the roundness of the steel ring and whether there is a depression on the inner side of the steel ring in real time; ultimately solving the problem of low detection accuracy of the existing device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4 This utility model discloses a testing device for bicycle rim production, comprising a base 1, a first support rod 2 and a second support rod 6 mounted on the upper end of the base 1. The base 1 facilitates the installation of a positioning mechanism; the first support rod 2 facilitates the installation of a testing mechanism; and the second support rod 6 facilitates the positioning of the rim in conjunction with the first support rod 2. A first sliding groove is laterally formed at the front end of the base 1, and a positioning mechanism is mounted on the top surface of the base 1. A second sliding groove is vertically formed at the front end of the first support rod 2. Testing mechanisms are slidably mounted on both the first and second sliding grooves, facilitating the detection of whether there are any dents inside the rim. Positioning rollers 3 are installed on the inner sides of the upper ends of the first support rod 2 and the second support rod 6, which facilitates fixing the steel ring and driving the steel ring to rotate. Second motors 7 are installed on the outer sides of the upper ends of the first support rod 2 and the second support rod 6, which facilitates driving the positioning rollers 3 to rotate. The output end of the second motor 7 is connected to the rotating shaft of the positioning roller 3. The positioning mechanism includes a first motor 4 installed on one side of the top surface of the base 1, which facilitates driving the lead screw 5 to rotate. The lead screw 5 is installed on the first motor 4 through a coupling, which facilitates driving the second support rod 6 to move towards the first support rod 2.

[0020] In this invention, the bottom end of the first support rod 2 is fixedly connected to the top surface of the base 1, and a guide hole is provided at the lower part of the first support rod 2 to pass through the lead screw 5. The bottom end of the second support rod 6 slides against the top surface of the base 1, and a threaded hole is provided at the lower part of the second support rod 6 to cooperate with the lead screw 5. The detection mechanism includes an I-shaped slider 8 slidably installed in the first and second slide grooves, through which a telescopic rod 9 is easily installed; the top surface of the slider 8 is hinged to the telescopic rod 9, through which a connecting block 10 is easily installed; the connecting block 10 is rotatably installed on the telescopic rod 9, through which a pressure sensor 11 is easily installed; the other end of the connecting block 10 is equipped with a pressure sensor 11, through which a vibration is easily detected to detect whether there is a dent on the inner side of the steel ring; the output end of the pressure sensor 11 is fixedly connected to a connecting rod 12, through which a detection wheel 13 is easily installed; the other end of the connecting rod 12 is equipped with a detection wheel 13, through which a contact with the inner side of the steel ring is easily rotated.

[0021] In this invention, the pressure sensor is a HS-100 vibration acceleration sensor.

[0022] Working Principle: When using this invention, first connect the power supply, place the steel ring inside the two positioning rollers 3, then start the first motor 4 and drive the lead screw 5 to rotate. The lead screw 5 drives the second support rod 6 to move towards the first support rod 2. When the two positioning rollers 3 clamp the steel ring, the first motor 4 stops. At this time, rotate the telescopic rods 9 on the two detection mechanisms respectively and adjust the length of the telescopic rods 9 until the detection wheel 13 abuts against the inner side of the steel ring. Then start the second motor 7. The second motor 7 drives the steel ring to rotate through the positioning rollers 3. At the same time, the detection wheel 13 rotates inside the steel ring. When the inner circle of the steel ring is not standard or there is a groove on the inner side, the detection wheel 13 will move laterally or longitudinally, thus generating vibration. This vibration will be transmitted to the pressure sensor 11. When the pressure sensor 11 receives the signal, it will immediately transmit the signal to the cloud and determine the fault location based on the number of rotations and the rotation speed to remind the inspection personnel. After the inspection is completed, remove the device and turn off the power.
