Description

Technical Field

[0001] This utility model relates to the field of carbon fiber wheel set technology, specifically a prefabricated fixture for producing carbon fiber wheel sets to prevent wheel slippage. Background Technology

[0002] Carbon fiber wheelsets are favored by many cycling enthusiasts for their lightweight, high strength, and good aerodynamic properties. Carbon fiber materials can effectively reduce the overall weight of a bicycle while providing sufficient rigidity to cope with complex and varied mountain road conditions. In addition, carbon fiber wheelsets generally have better durability and corrosion resistance, making them suitable for long-term use.

[0003] The above technical conditions also have defects: the existing carbon fiber wheel set prefabrication fixtures lack a precise positioning structure during the assembly process, which can easily cause the wheel set to shift during curing, affecting the product accuracy.

[0004] Based on this, this utility model designs a prefabricated fixture for the production of carbon fiber wheelsets to prevent misalignment, in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a prefabricated fixture for the production of carbon fiber wheelsets that prevents them from shifting, in order to solve the above-mentioned technical problems.

The wheelset body is disposed inside the cavity formed between the top ring, the middle ring, and the bottom ring. Multiple alignment blocks are fixedly disposed at the bottom of the bottom ring, and multiple alignment grooves adapted to the alignment blocks are disposed on the middle ring.

[0007] By adopting the above technical solution, the alignment block and the alignment groove work together to achieve precise positioning of the bottom ring and the middle ring, preventing the wheel set from shifting during the prefabrication process and ensuring product accuracy.

[0008] Preferably, the top ring has multiple positioning holes, and a pressure monitoring mechanism is installed in some of the positioning holes.

[0009] By adopting the above technical solution, the pressure monitoring mechanism can monitor the pressure distribution between the middle ring and the top ring in real time, avoiding uneven pressure that could lead to wheel deformation.

[0010] Preferably, the pressure monitoring mechanism includes a pressure sensor, the top of which is fixedly connected to the inside of a positioning hole on the top ring, a spring is fixedly connected to the bottom of the pressure sensor, and a contact block is fixedly connected to the bottom end of the spring.

[0011] By adopting the above technical solution, the spring buffers the pressure and transmits it to the sensor, and the contact block directly abuts against the middle ring, providing sensitive feedback of pressure data.

[0012] Preferably, the pressure monitoring mechanism consists of three groups, which are intermittently arranged on multiple positioning holes.

[0013] By adopting the above technical solution, three sets of monitoring points can cover the circumference range at minimal cost and efficiently detect pressure uniformity.

[0014] Preferably, the alignment block and the alignment groove are provided in three sets, and the interval between each two sets is 120°.

[0015] By adopting the above technical solution, the 120° symmetrical distribution ensures force balance and further improves positioning stability.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-2This application will be described in further detail.

[0024] A prefabrication fixture for producing carbon fiber wheelsets with anti-deviation features includes a top ring 1, a middle ring 2, a wheelset body 3, and a bottom ring 4. The wheelset body 3 is disposed inside the cavity formed between the top ring 1, the middle ring 2, and the bottom ring 4, which allows for pre-forming of the wheelset body 3, facilitating subsequent processing. Multiple alignment blocks 5 are fixedly disposed at the bottom of the bottom ring 4, and multiple alignment grooves 6 that are adapted to the alignment blocks 5 are disposed on the middle ring 2, enabling precise alignment between the bottom ring 4 and the middle ring 2, preventing deviation during subsequent processing, and improving the prefabrication effect.

[0025] Furthermore, multiple positioning holes 7 are provided on the top ring 1, and pressure monitoring mechanisms 8 are installed in some of the positioning holes 7. The pressure monitoring mechanisms 8 can monitor the pressure value between the middle ring 2 and the top ring 1 in real time and promptly remind people when abnormalities occur.

[0026] Furthermore, the pressure monitoring mechanism 8 includes a pressure sensor 81. The top of the pressure sensor 81 is fixedly connected to the inside of the positioning hole 7 on the top ring 1. A spring 82 is fixedly connected to the bottom of the pressure sensor 81, and a contact block 83 is fixedly connected to the bottom of the spring 82. After the middle ring 2 is installed on the top ring 1, the bottom of the contact block 83 abuts against the top of the middle ring 2, thereby compressing the spring 82. At this time, the pressure sensor 81 reads a value. If the value remains basically unchanged, it indicates that the middle ring 2 and the top ring 1 are in good contact. If an abnormality occurs, it indicates that there is a problem with the contact between the middle ring 2 and the top ring 1.

[0027] Furthermore, both the alignment block 5 and the alignment groove 6 are provided with three sets, and each pair of sets is spaced 120° apart, which makes the force more uniform.

[0028] Furthermore, there are three groups of pressure monitoring mechanisms 8, which are intermittently arranged on multiple positioning holes 7, that is, there are two positioning holes 7 on both sides of each pressure monitoring mechanism 8 where no pressure monitoring mechanism 8 is installed.

[0029] The implementation principle of this embodiment is as follows: the middle ring 2 is placed on the bottom ring 4, and the alignment block 5 of the bottom ring 4 is inserted into the alignment groove 6 of the middle ring 2 to achieve precise positioning of the three rings. Then, the wheel assembly body 3 is placed on the middle ring 2, and finally the top ring 1 is placed on the middle ring 2. The middle ring 2 and the top ring 1 are aligned and installed through the positioning hole 7. At this time, the bottom of the contact block 83 abuts against the top of the middle ring 2, the spring 82 is compressed and the pressure is transmitted to the pressure sensor 81. During the pressing process, the pressure sensor 81 monitors the pressure at each point in real time. If the value is abnormal, it prompts for adjustment to ensure that the pressure is evenly distributed.
