[0029] Example

[0030] Please refer to Figure 1 As shown, this embodiment provides a fixing device for gluing plastic parts, comprising: a substrate 10, a cover plate 20, and a positioning assembly 30. The cover plate 20 is rotatably mounted on the substrate 10, and an adjustable accommodation space 201 is formed between the cover plate 20 and the substrate 10. The fixed plastic part is inserted into the accommodation space 201, and the cover plate 20 rotates toward the substrate 10 to abut against the plastic part, so as to achieve the fixing of the plastic part by the cover plate 20; the positioning assembly 30 is installed in the accommodation space 201, and the positioning assembly 30 is used to abut against the plastic part to fix the relative position between the plastic part and the substrate 10.

[0031] In this embodiment, the substrate 10 and the cover plate 20 are U-shaped, and the substrate 10 and the cover plate 20 are arranged relative to each other, and a receiving space 201 is formed between the two. The glued plastic parts are placed in the receiving space 201, and the cover plate 20 is driven to rotate toward the substrate 10 to abut against the surface of the plastic parts, and the relative position between the substrate 10 and the cover plate 20 is fixed, so that the glued plastic parts can be fixed. The positioning assembly 30 is installed on the inner wall side of the receiving space 201, and is used to position and clamp the plastic parts to improve the gluing accuracy. The snap-fit ​​fixation of the substrate 10 and the cover plate 20 further protects the glued plastic parts from dislocation, bumps and scratches caused by external forces during the fixing process.

[0032] Further, in some implementations of this embodiment, Figures 1 to 4As shown, the positioning assembly 30 includes: a positioning plate 301, a first positioning block 302, and a second positioning block 303. The positioning plate 301 is mounted on the substrate 10; the first positioning blocks 302 are symmetrically mounted on both sides of the substrate 10, and the first positioning blocks 302 move relative to the substrate 10; the second positioning block 303 is mounted on the positioning plate 301.

[0033] In this embodiment, a positioning plate 301 is installed on an opening on one side of the substrate 10, and is used to cooperate with the substrate 10 to preliminarily position the glued plastic part. The first positioning block 302 is installed on the inner walls on both sides of the substrate 10. The first positioning block 302 slides relative to the substrate 10 to adapt to plastic parts with size changes on the two relative sides, improve the applicability of the device, and improve the stability and reliability of the device positioning. The second positioning block 303 is a columnar block, which abuts and positions one side of the plastic part, and cooperates with the first positioning blocks 302 distributed on both sides of the substrate 10 to clamp the plastic part, thereby reducing the dislocation and slippage caused by the cover plate 20 rotating to abut the plastic part, and further improving the stability of the device fixation.

[0034] Further, in some implementations of this embodiment, Figure 2 and Figure 3 As shown, the positioning assembly 30 further includes a pressing plate 304 . The pressing plate 304 has a mounting groove 305 formed on the cover plate 20 . The pressing plate 304 is slidably mounted in the mounting groove 305 . The pressing plate 304 moves relative to the cover plate 20 toward the accommodation space 201 .

[0035] In this embodiment, the pressure plate 304 is slidably mounted on the inner side of the cover plate 20 to float against the upper surface of the plastic part to improve the stability of the contact, to compensate for the angle change caused by the rotation of the cover plate 20, and to improve the uniformity of the external force applied to the upper surface.

[0036] Further, in some implementations of this embodiment, Figures 1 to 5 As shown, the device further includes: a mounting member 401, a limiting rod 402, and a pressing block 403. The mounting member 401 has a rotation groove 202 on the cover plate 20, and the mounting member 401 is rotatably mounted in the rotation groove 202; the limiting rod 402 is mounted on the mounting member 401, and a limiting groove 101 is provided on the substrate 10. The limiting rod 402 rotates toward the substrate 10 as the mounting member 401 rotates, so as to drive the limiting rod 402 to extend into the limiting groove 101; the pressing block 403 is slidably arranged on the limiting rod 402, and the pressing block 403 slides along the axis of the limiting rod 402 toward the substrate 10 to abut against the substrate 10, thereby fixing the relative position between the substrate 10 and the cover plate 20.

[0037] In this embodiment, the mounting member 401 is rectangular and has a circular cross section, and the rotation groove 202 is a semicircular groove corresponding to the mounting member 401 to facilitate the rotation of the mounting member 401 relative to the cover plate 20. Figure 1 As shown, the driving mounting member 401 is rotated toward the substrate 10, and the limiting rod 402 is rotated into the limiting groove 101 to limit the displacement of the mounting member 401 along the axial direction of the rotating groove 202. The clamping block 403 and the limiting rod 402 are threadedly connected. The clamping block 403 is rotated to drive the clamping block 403 to move along the axis of the limiting rod 402 toward the substrate 10 to abut against the substrate 10, thereby fixing the relative position between the substrate 10 and the cover plate 20, thereby improving the stability of the installation of the cover plate 20 and the substrate 10.

[0038] Further, in some implementations of this embodiment, Figures 1 to 4 As shown, the device also includes: a stop block 102 is installed at the mouth of the limiting groove 101; a sliding groove 103 is opened on the inner wall of the substrate 10, and the first elastic element 306 is installed in the sliding groove 103, and the first elastic element 306 is installed between the first positioning block 302 and the sliding groove 103; the second elastic element 307 is installed in the installation groove 305, and the second elastic element 307 is installed between the cover plate 20 and the pressure plate 304.

[0039] In this embodiment, the stopper 102 is installed to abut against the peripheral side of the pressing block 403 to prevent the pressing block 403 from sliding out of the limiting groove 101, thereby improving the reliability of the installation of the cover plate 20 and the substrate 10. The first elastic element 306 and the second elastic element 307 can be springs. The installation of the first elastic element 306 applies an external force toward the fixed plastic part to the first positioning block 302, keeps the first positioning block 302 in contact with the plastic part, and improves the positioning accuracy of the device. The installation of the second elastic element 307 improves the floating property of the pressing plate 304, thereby improving the uniformity of the contact of the pressing plate 304 with the plastic part.

[0040] Further, in some implementations of this embodiment, Figure 4 As shown, there are multiple first positioning blocks 302 , which are arranged in groups of two. A group of first positioning blocks 302 is installed on both sides of the substrate 10 .

[0041] In this embodiment, two positioning blocks are relatively arranged on both sides of the base plate 10 as a group, so as to improve the stable clamping and fixing of the plastic parts by both sides of the base plate 10 and reduce the position slippage of the plastic parts during the installation and fixing process.

[0042] Further, in some implementations of this embodiment, Figure 4 There are multiple second positioning blocks 303 , which are distributed on the positioning plate 301 at intervals.

[0043] In this embodiment, there are three second positioning blocks 303, which are spaced apart on the positioning plate 301, so as to improve the positioning effectiveness between the positioning plate 301 and the plastic plate, adapt to the positioning of plastic parts with size changes on the peripheral side, and improve the applicability of the device.

[0044] Further, in some implementations of this embodiment, Figures 1 to 4 As shown, the contact surfaces between the first positioning block 302 and the second positioning block 303 and the plastic part are both curved surfaces.

[0045] In this embodiment, the curved surfaces of the contact surfaces between the first positioning block 302 and the second positioning block 303 and the plastic part reduce the contact area to increase the clamping force on the plastic part, prevent adhesion between the positioning assembly 30 and the plastic part caused by surface-to-surface contact, and improve the reliability of the device in positioning the plastic part.

[0046] To summarize, when a fixing device for gluing plastic parts is used to glue and fix plastic parts, the fixed plastic part is slid into the substrate 10, and the plastic part is initially clamped on the substrate 10 by the first positioning component 30 and the second positioning component 30, and the cover plate 20 is driven to rotate toward the substrate 10 to abut the plastic part, driving the pressure plate 304 to press the upper surface of the plastic part, and the mounting part 401 is rotated to drive the limiting rod 402 to rotate into the limiting groove 101, and the pressing block 403 is rotated to abut the substrate 10 to fix the relative position of the substrate 10 and the cover plate 20, thereby reducing the tedious operation of clamping the glued plastic parts in multiple places with multiple fixing clamps, providing more convenient, fast and reliable fixation, thereby improving processing efficiency.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
