[0038] The pen neck guard assembly fixture includes a top plate 1, a bottom plate 2, a pressure plate 3, and a pen neck fixing platform 4. The top plate 1 includes a top plate body 11 and an ejector pin 12 provided on the top plate body 11; the bottom plate 2 includes a bottom plate body 21, a fixing pin 22 provided on the bottom plate body 21, and an ejector pin hole 23; the pressure plate 3 has a fixing pin hole 31, and the fixing pin 22 passes through the fixing pin hole 31 to movably connect the bottom plate 2 and the pressure plate 3; the pen neck fixing platform 4 includes a pen neck fixing portion for fixing the pen neck 101 and making the pen neck 101 coaxial with the fixing pin 22;
[0039] Among them, the top plate 1, the bottom plate 2, the pressure plate 3 and the pen neck fixing platform 4 are arranged in sequence along the axial direction of the pen neck, and the ejector pin 12 passes through the ejector pin hole 23 and abuts against the pressure plate 3; when the top plate 1 moves toward the pen neck fixing platform 4, the ejector pin 12 pushes the pressure plate 3 to slide along the fixing pin 22, so that the sheath 102 sleeved on the fixing pin 22 is installed on the pen neck 101 of the pen neck fixing part.
[0040] refer to Figure 1 The overall assembly diagram of the pen neck guard assembly fixture shown is as follows, Figure 2 A schematic diagram of the sheath 102 is shown, Figure 3 The schematic diagram of the pen neck 101 to be assembled with the sheath 102 is shown, and Figure 4 The schematic diagram of the assembled sheath 102 and the pen neck 101 is shown.
[0041] During assembly, pressure is applied to the top plate 1 in the direction of the pen neck fixing platform 4 (downward in the figure as an example). The pressure acts on the pressure plate 3 through the top pin 12, and then acts on the sheath 102 sleeved on the fixing pin 22 through the pressure plate 3. The sheath 102 moves downward under the pressure and is gradually installed on the pen neck 101, which can make the installation of the pen neck 101 and the sheath 102 more convenient and improve the assembly efficiency. In addition, since the sheath 102 is gradually put on the pen neck 101 by pressing down on the pressure plate 3, the exemplary embodiment of the present disclosure can also improve the success rate of assembly. For example, when installing a very soft sheath 102 with a hardness of only 7 to 8 degrees on the pen neck 101, the pen neck sheath assembly fixture disclosed in the present disclosure can stably assemble the sheath 102 to the pen neck 101.
[0042] In an exemplary embodiment of the present disclosure, referring to Figure 1 The overall assembly diagram of the pen neck guard assembly fixture shown and Figure 5 In the schematic diagram of the base plate 2 shown, the distance between the fixing pin 22 and the pen neck 101 at the fixing portion of the pen neck is shorter than the length of the sheath 102. For example, the fixing pin 22 can be cylindrical. As the pressing plate 3 pushes the sheath 102 toward the pen neck fixing platform 4, thereby gradually installing it on the pen neck 101, the sheath 102 is unlikely to become detached from the fixing pin 22 and the pen neck 101.
[0043] In an exemplary embodiment of the present disclosure, the length of the ejector pin 12 is greater than the distance from the pressing plate 3 to the pen neck fixing platform 4. Figure 1 The overall assembly diagram of the pen neck guard assembly fixture shown, Figure 6 The schematic diagram of the top plate 1 shown, Figure 7 The schematic diagram of the pen neck fixing platform 4 shown and Figure 8 The pen neck fixing part shown is a schematic diagram of fixing the pen neck 101.
[0044] The distance between the pressing plate 3 and the pen neck fixing platform 4 described in the present disclosure may refer to the minimum distance between the pressing plate 3 and the pen neck fixing platform 4, for example, the distance from the surface of the pressing plate 3 closest to the pen neck fixing platform 4 to the surface of the pen neck fixing platform 4 closest to the pressing plate 3. For example, the top plate 1, the bottom plate 2, the pressing plate 3, and the pen neck fixing platform 4 are arranged in sequence from top to bottom along the vertical direction, and the ejector pins 12, the fixing pins 22, and the axis of the pen neck 101 fixed to the pen neck fixing platform 4 are all along the vertical direction. During the process of the pressing plate 3 pressing down the sheath 102, the ejector pins 12 can continue to push the pressing plate 3 until the sheath 102 is completely inserted into the pen neck 101.
[0045] In other exemplary embodiments, the top plate 1, bottom plate 2, pressing plate 3 and pen neck fixing platform 4 may be arranged in sequence along the horizontal direction. In other exemplary embodiments, the top plate 1, bottom plate 2, pressing plate 3 and pen neck fixing platform 4 may be arranged in sequence from bottom to top along the vertical direction, that is, Figure 1 The general assembly drawing is shown oriented upside down.
[0046] In an exemplary embodiment of the present disclosure, referring to Figure 1 、 Figure 5 as well as Figure 6 As shown, the diameter of the fixing needle 22 is larger than the diameter of the ejector pin 12. For example, the diameter of the fixing needle 22 may be 8 to 20 mm, and the diameter of the ejector pin 12 may be 5 to 10 mm.
[0047] In an exemplary embodiment of the present disclosure, the diameter of ejector pin hole 23 is greater than or equal to the diameter of ejector pin 12. For example, the clearance fit between ejector pin 12 and ejector pin hole 23 reduces the resistance of ejector plate 1 to the downward pressure of pressing plate 3. For example, retaining pin 22 and sheath 102 have an interference fit to prevent sheath 102 from falling off. For example, sheath 102 can be made of an elastic material such as rubber and stretched to fit over retaining pin 22.
[0048] In an exemplary embodiment of the present disclosure, the portion where the fixing needle 22 passes through the pressing plate 3 may also be provided with an anti-slip section, and the sheath 102 is sleeved on the anti-slip section to prevent the sheath 102 from falling off by itself.
[0049] In an exemplary embodiment of the present disclosure, a plurality of ejector pins 12 may be provided on the ejector plate 11, and a plurality of ejector pin holes 23 corresponding to each other may be provided on the bottom plate 21; the plurality of ejector pins 12 pass through the ejector pin holes 23 and abut against the pressing plate 3. Figure 1 For the sake of illustration, Figure 1 An exemplary embodiment is shown in which a top plate body 11 is provided with a ejector pin 12, and a bottom plate body 21 is provided with an ejector pin hole 23 corresponding to the ejector pin 12. In an exemplary embodiment of the present disclosure, for example, two ejector pins 12 may be provided on the top plate body 11, respectively provided at the two ends of a diagonal line of the top plate body 11, or respectively provided at the two ends of a long side of the top plate body 11, or respectively provided at the two ends of a short side of the top plate body 11. For another example, four ejector pins 12 may be provided on the top plate body 11, respectively provided near the four corners of the top plate body 11, to apply uniform and stable pressure to the pressure plate 3. In some exemplary embodiments, more ejector pins 12 may be provided on the top plate body 11, and more ejector pin holes 23 may be provided on the bottom plate body 21, as long as the ejector pins 12 and the ejector pin holes 23 correspond one to one.
[0050] In an exemplary embodiment of the present disclosure, a plurality of ejector holes 23 on the bottom plate body 21 are circumferentially arranged on one side of the fixing pin 22 near the outer edge of the bottom plate body 21. For example, the fixing pin 22 can be arranged near the center of the bottom plate body 21, and the ejector holes 23 can be arranged at the edge of the bottom plate body 21. For example, for any fixing pin 22, its minimum distance from any edge of the bottom plate body 21 is not less than the minimum distance from the ejector hole 23 closest to the edge to the edge. Exemplarily, four ejector holes 23 are provided on the bottom plate body 21, respectively, at the four corners of the bottom plate body 21, and the fixing pin 22 is provided at the center of the bottom plate body 21.
[0051] refer to Figure 9 The schematic diagram of the pressing plate 3 shown is for the convenience of illustration. Figure 5 It is shown that a fixing pin 22 is provided on the bottom plate 21. Figure 9 An exemplary embodiment in which a fixing pin hole 31 is provided on the pressing plate 3 is shown. In an exemplary embodiment of the present disclosure, a plurality of fixing pins 22 may be provided on the bottom plate body 21, the pressing plate 3 has a plurality of fixing pin holes 31 corresponding one-to-one to the fixing pins 22, and the pen neck fixing platform 4 includes a plurality of pen neck fixing parts for fixing a plurality of pen necks 101 and making the pen necks 101 coaxial with the fixing pins 22 in a one-to-one correspondence. This exemplary embodiment can realize batch assembly of a plurality of pen necks 101 and sheaths 102, that is, by pushing the top plate 1 once, a plurality of sheaths 102 can be installed on the corresponding pen necks 101 at one time. Exemplarily, the bottom plate body 21 can be a rectangular flat plate, and the plurality of fixing pins 22 are evenly distributed on the bottom plate body 21 in an array along the length and width directions of the bottom plate body 21. A plurality of top pin holes 23 are circumferentially arranged on the outer edges of the plurality of fixing pins 22.
[0052] refer to Figure 10 The schematic diagram of the assembly of the base plate 2, the pressing plate 3 and the sheath 102 is shown. In an exemplary embodiment of the present disclosure, the length of the fixing needle 22 extending from the pressing plate 3 is less than the length of the sheath 102, which can improve the efficiency of the assembly.
[0053] For example, refer to Figure 7 、 Figure 8 As shown, the pen neck fixing platform 4 can be a rectangular box-shaped structure, and the pen neck fixing part is arranged inside the pen neck fixing platform 4, for example, a hole adapted to the shape of the pen neck 101, so that the axis of the pen neck 101 can be stably fixed to the pen neck fixing platform 4.
[0054] Other embodiments of the present disclosure will readily occur to those skilled in the art after considering the specification and practicing the utility model disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein.
