[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.
[0020] Please refer to Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A schematic structural diagram of a preferred embodiment of a spoke that is easy to process and position provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the positioning sleeve installation structure is shown; Figure 3 for Figure 1 The schematic diagram of the pin installation structure shown in the figure is a spoke that is easy to process and position, comprising: a spoke body 1, a mounting sleeve 2 is fixedly installed at the top center point of the spoke body 1, a positioning sleeve 3 is sleeved on the top of the mounting sleeve 2, a first positioning groove 11 is equidistantly opened on the outside of the mounting sleeve 2, and the number of the first positioning grooves 11 is four, a second positioning groove 12 is equidistantly opened on the outside of the positioning sleeve 3, and the number of the second positioning grooves 12 is four, a pin 8 is penetrated through the second positioning groove 12 on the outside of the mounting sleeve 2, one end of the pin 8 penetrates the positioning sleeve 3 through the first positioning groove 11, and the positioning sleeve 3 and the mounting sleeve 2 are connected by a pin The spokes are fixed with nails 8. After the spokes are formed, their exterior needs to be ground and polished to make their surface smooth for easy installation with the foam wheel. The positioning sleeve 3 and the installation sleeve 2 are installed, and the pins 8 pass through the first positioning groove 11 and the second positioning groove 12 respectively, thereby effectively fixing the positioning sleeve 3 and the installation sleeve 2. The exterior of the positioning sleeve 3 is clamped by a three-jaw chuck, and the spoke body 1 is driven to rotate by the rotation of the three-jaw chuck, thereby facilitating the grinding and polishing of its surface. At the same time, the damage of the spoke caused by direct clamping of the three-jaw chuck is avoided, and the function of facilitating processing and positioning is achieved.
[0021] A sleeve 4 is fixedly installed in an equidistant ring outside the positioning sleeve 3 and at the center point of the four first positioning grooves 11, and the number of sleeves 4 is four. An end cover 5 is fixedly installed at one end of the four sleeves 4, and a sliding rod 6 passes through the center point of the four end covers 5. A limiting ring 7 is fixedly installed outside the four sliding rods 6 and inside the sleeve 4. The outer surface of the limiting ring 7 fits with the inner surface of the sleeve 4. The sliding stability of the sliding rod 6 is guaranteed by the limiting ring 7. At the same time, the limiting ring 7 plays a role of blocking and limiting the spring 9.
[0022] One end of the slide bar 6 is fixedly installed with the pin 8, and the other end of the slide bar 6 is fixedly installed with a handle 10 on the outer side of the end cover 5. Springs 9 are sleeved on the outside of the four slide bars 6 and between the limit ring 7 and the end cover 5. When installing the positioning sleeve 3 and the installation sleeve 2, the four slide bars 6 are pulled outward by the handle 10. At this time, the slide bar 6 slides outward, the spring 9 is compressed, and the pin 8 moves to the inside of the sleeve 4. After the first positioning groove 11 is aligned with the second positioning groove 12, the handle 10 is slowly loosened. Due to the reset effect of the spring 9, the slide bar 6 drives the pin 8 to move, and the pin 8 penetrates the positioning sleeve 3 and the installation sleeve 2, thereby effectively fixing them. When removing the positioning sleeve 3, the handle 10 is pulled outward again, the pin 8 enters the inside of the sleeve 4, and the fixation of the positioning sleeve 3 and the installation sleeve 2 is released. The structure is simple and convenient for installation or disassembly.
[0023] The working principle of the spoke provided by the utility model that is easy to process and position is as follows:
[0024] The first step: after the spoke is formed, it is necessary to grind and polish its exterior to make its surface smooth for easy installation with the foam wheel. The positioning sleeve 3 and the installation sleeve 2 are installed, and the four slide bars 6 are pulled outward by the handle 10. At this time, the slide bar 6 slides outward, the spring 9 is compressed, and the pin 8 moves to the inside of the sleeve 4. After the first positioning groove 11 is aligned with the second positioning groove 12, the handle 10 is slowly loosened. Due to the reset effect of the spring 9, the slide bar 6 drives the pin 8 to move. The pin 8 passes through the first positioning groove 11 and the second positioning groove 12 respectively, thereby effectively fixing the positioning sleeve 3 and the installation sleeve 2, and then the three-jaw chuck is used to clamp the exterior of the positioning sleeve 3. The rotation of the three-jaw chuck drives the spoke body 1 to rotate, thereby facilitating the grinding and polishing of its surface. At the same time, the three-jaw chuck is prevented from directly clamping and causing damage to the spoke, and it has the function of facilitating processing and positioning.
[0025] Step 2: When removing the positioning sleeve 3, pull the handle 10 outward again, and the pin 8 enters the interior of the sleeve 4. The fixation between the positioning sleeve 3 and the installation sleeve 2 is released. The structure is simple and convenient for installation or disassembly. The sliding stability of the slide rod 6 is guaranteed by the limit ring 7. At the same time, the limit ring 7 plays a role of blocking and limiting the spring 9.
[0026] Compared with the related art, the spoke provided by the utility model is easy to process and position and has the following advantages:
[0027] Beneficial effects:
[0028] After the spoke is formed, its exterior needs to be ground and polished to make its surface smooth for easy installation with the foam wheel. The positioning sleeve 3 and the installation sleeve 2 are installed, and the pin 8 passes through the first positioning groove 11 and the second positioning groove 12 respectively, thereby effectively fixing the positioning sleeve 3 and the installation sleeve 2, and then the three-jaw chuck is used to clamp the exterior of the positioning sleeve 3. The rotation of the three-jaw chuck drives the spoke body 1 to rotate, thereby facilitating the grinding and polishing of its surface, while avoiding damage to the spoke caused by direct clamping of the three-jaw chuck, and having the function of facilitating processing and positioning.
