Abstract
Description
Technical Field
[0001] The utility model relates to the field of mechanical processing equipment, in particular to a grinding device. Background Art
[0002] A stylus pen is an auxiliary tool that facilitates the use of electronic devices. It generally includes a pen barrel, a contact, and internal electronic components, with the contact mounted at the tip of the pen barrel. The pen barrel is typically an injection-molded part. Since the injection mold is typically composed of two parts, after the pen barrel is injection-molded, one or two parting lines often protrude outward from the circumferential wall of the pen barrel. Therefore, after the initial injection molding of the pen barrel, the circumferential wall of the pen barrel needs to be polished to remove the parting lines and achieve a smooth circumferential wall. However, because the parting lines on the pen barrel are very thin and elongated, milling and polishing this circumferential surface using a traditional CNC lathe tool is time-consuming and inefficient due to the slow tool feed and the long time required to remove the pen barrel after polishing.

In this embodiment, the grinding mechanism 1 includes two grinding motors 12 and two corresponding grinding wheels 11, thereby simultaneously grinding two pen tubes 200 to improve grinding efficiency. The grinding wheels 11 are detachably mounted on the output end of the grinding motor 12 for easy replacement, thereby ensuring a good grinding effect. Furthermore, the grinding motor 12 is a servo motor, and the lifting cylinder 13 and the first cylinder 42 are both hydraulic cylinders.
[0027] Further, see Figure 1 、 Figure 2 and Figure 5 The locking member 20 includes an operating handle 201, a linkage rod 202 and a mounting seat 203. The mounting seat 203 is fixedly arranged on the grinding platform 3. One end of the operating handle 201 is pivotally connected to one side of the mounting seat 203. One end of the linkage rod 202 is pivotally connected between the two ends of the operating handle 201 and the other end is pivotally connected to the second accommodating member 22 to enable the operating handle 201 to be linked with the second accommodating member 22.

[0030] The following describes the operating principle of the grinding device 100 provided by the present invention. First, the end of the pen tube 200 opposite the tip is inserted into the second accommodating cavity 221 of the second accommodating member 22. The pen tube 200 is then rotated about its own axis so that the parting line of the pen tube 200 faces the grinding wheel 11 of the grinding mechanism 1. The second accommodating member 22 is then driven toward the first accommodating member 21 via the operating handle 201 and the linkage rod 202 until the tip of the pen tube 200 extends into the first accommodating cavity 211. When both ends of the linkage rod 202 are rotated to the locked position, the operating handle 201, the second accommodating member 22, and the pen tube 200 are all locked. At this point, the grinding wheel 11 of the grinding mechanism 1 is then driven toward the pen tube 200 to grind the parting line 300 of the pen tube 200. To ensure a good grinding effect, the grinding wheel 11 needs to move back and forth. After polishing is complete, the polishing mechanism 1 is first moved away from the pen barrel 200. The second accommodating member 22 is then released using the operating handle 201, allowing the tip of the pen barrel 200 to leave the first accommodating member 21. The polished pen barrel 200 is then removed, and the polishing process is now complete. After one polishing session is completed, the pen barrel 200 to be polished is replaced and the next polishing session can begin.
[0031] Compared with the prior art, the grinding device 100 provided by the present invention is provided with a fixing mechanism 2 having a first accommodating member 21 and a second accommodating member 22 to fix the two ends of the pen tube 200, and a locking member 20 is provided to drive the second accommodating member 21 to move and lock the second accommodating member 21, thereby locking the pen tube 200 between the first accommodating member 21 and the second accommodating member 22, and a movable grinding mechanism 1 is provided above the grinding platform 3, so that the grinding mechanism 1 is convenient to approach the pen tube 200 to grind the pen tube 200. The parting line 300 of the pen tube 200 is close to or away from the pen tube 200 so that the polished pen tube 200 can be quickly removed and replaced with the pen tube 200 to be polished, and the end surface of the polishing wheel 11 of the polishing mechanism 1 facing the polishing platform 3 is the polishing surface 110, which facilitates the polishing wheel 11 to polish the parting line 300 of the pen tube 200; therefore, the polishing device 100 of the present invention is easy to operate during the polishing process, and it is also very quick to remove the polished pen tube 200 and replace it with the pen tube 200 to be polished, which saves time and has high polishing efficiency.
