Description

Technical Field

[0001] The utility model relates to the field of plastic parts, in particular to an assembly jig for plastic parts. Background Art

[0002] Plastic parts are a common component. The structural parts and appearance parts of many products often use plastic parts. Some plastic parts will be installed with embedded nuts during the actual production process. Embedded injection molding is a process in which metal nuts are placed on positioning pins and then molded and injection molded. Subsequent staff use bolt assemblies to assemble the embedded nuts with the required hardware.

[0003] The existing embedded nut assembly is manually performed by staff. First, the through hole of the hardware is aligned with the embedded nut, and then the screw is inserted into the embedded nut through the hardware. Finally, the screw is turned and tightened to complete the overall assembly work. However, in actual operation, it is difficult for staff to ensure the accuracy between the hardware and the embedded nut, resulting in difficulty in quickly positioning the hardware and the embedded nut, thereby reducing the overall assembly efficiency. In addition, if the screw is tilted during the assembly process, it will cause distortion and misalignment during the twisting process, which will damage the embedded nuts of the hardware and plastic parts.

[0004] In summary, the above structure is difficult to ensure the accuracy between the hardware and the embedded nuts during use. If the screws are tilted during assembly, they will cause distortion and misalignment during twisting, thereby damaging the embedded nuts of the hardware and plastic parts. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide an assembly jig for plastic parts to solve the technical problems of reducing the overall assembly efficiency during use, and causing distortion and misalignment during twisting, thereby damaging the embedded nuts of hardware and plastic parts.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an assembly jig for plastic parts, comprising a base and a cover, wherein an array of grooves is provided in the base, a bottom plate is elastically provided in the groove, an array of insertion rods is connected to the bottom of the bottom plate, and splints corresponding to the insertion rods are symmetrically provided in the horizontal direction in the groove, one end of the splint is elastically connected to a guide column, and a socket for inserting the insertion rod is provided on the guide column.

[0007] By adopting the above technical solution, the plastic part will be squeezed by the face cover to move the bottom plate downward. At this time, the insertion rod will slide downward and out of the socket. Under the action of the elastic component, the guide column drives the splint to clamp the plastic part in the groove. Through the action of the hardware positioning groove, the through hole on the hardware and the embedded nut are in the same vertical direction. In this process, it is ensured that there will be no tilting or misalignment during the twisting of the screw.

[0008] The present invention is further configured such that a plurality of hardware positioning grooves corresponding to the grooves are provided on the top of the surface cover, and the hardware positioning grooves are arranged in a trapezoidal shape as a whole.

[0009] By adopting the above technical solution, the hardware positioning groove facilitates direction determination and positioning through the trapezoidal hole, wherein the specific shape of the hardware positioning groove can be changed through the hardware, which facilitates the staff to further improve the positioning efficiency of the hardware itself during subsequent installation.

[0010] The present invention is further configured such that the bottom of the jack is configured in an open shape.

[0011] By adopting the above technical solution, the open-shaped setting makes it easier for the insertion rod to be stably inserted into the inside of the socket, and the opening itself plays a certain guiding role.

[0012] The present invention is further configured such that one end of the guide post and the bottom of the base plate are both provided with elastic components.

[0013] By adopting the above technical solution, when the plastic part is pressed down, the elastic component itself is in a compressed state, so that after the limit is subsequently released, the base plate can drive the plastic part to reset. At the same time, when the guide post is inserted into the rod, the elastic component is also in a compressed state, causing the splint to move toward the inner wall of the groove. When the rod is subsequently pulled out, the elastic component is reset to enable the splint to limit and clamp the plastic part.

[0014] The present invention is further configured such that a protective cover is provided on the inner side of the splint.

[0015] By adopting the above technical solution, the provision of the protective cover prevents the splint from directly contacting the outer wall of the plastic part, and further prevents the splint from causing wear to the outer wall of the plastic part during the assembly process.

[0016] The present invention is further configured such that a plurality of micro protrusions are provided on the top of the bottom plate.

[0017] By adopting the above technical solution, the micro-protrusions can increase the sliding friction between the bottom plate and the plastic part, thereby preventing the plastic part from shifting in position under slight external vibrations.

[0018] The present invention is further configured such that one end of the insertion rod is arranged in an arc shape.

[0019] By adopting the above technical solution, the arc-shaped setting facilitates the smoothness of the insertion rod when inserting it into the socket in the guide column, and the open setting at the bottom end of the socket prevents the insertion rod from getting stuck.

[0020] The present invention is further configured such that the outer wall of the insertion rod and the inner wall of the insertion hole are configured to be smooth.

[0021] By adopting the above technical solution, the smooth setting makes it easy to reduce the friction between the insertion rod and the socket, so that the subsequent insertion rod can easily slide out of the socket.

[0022] The present invention is further configured such that a slot for the bottom plate to be inserted is provided in the groove.

[0023] By adopting the above technical solution, when the plastic part drives the bottom plate to move downward, the bottom plate itself will be stuck in the inside of the card slot, so that the bottom plate and the groove are at the same horizontal height, ensuring the stability of the plastic part in the groove.

[0024] The present invention is further configured such that the base and the cover are connected via positioning guide posts.

[0025] By adopting the above technical solution, the guide column can be used to quickly position and connect the face cover, further accelerating the overall assembly efficiency.

[0026] In summary, the present invention has the following beneficial effects:

[0027] 1. The utility model places the plastic part on the bottom plate in the groove, and then covers the top of the base. At this time, the cover squeezes the plastic part to make the bottom plate move downward. At this time, the insertion rod slides downward and out of the insertion hole. Under the action of the elastic component, the guide column drives the clamping plate to clamp the plastic part in the groove. In this process, the stability of the plastic part is ensured during the assembly process with the hardware.

[0028] 2. The utility model provides a hardware positioning groove corresponding to the groove on the surface cover. Under the action of the hardware positioning groove, the through hole on the hardware and the embedded nut are in the same vertical direction. In this process, it is ensured that the screw will not tilt or misalign during the twisting process, further ensuring the installation effect between the hardware and the plastic part.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] The following describes an embodiment of the present invention based on its overall structure. Example 1

[0038] An assembly jig for plastic parts, such as Figures 1-6As shown, it includes a base 1, a cover 2, a positioning mechanism, a clamping mechanism and a reset mechanism. An array of grooves 10 is provided in the base 1, wherein a bottom plate 7 is elastically provided in the groove 10. The staff places the plastic part 9 to be assembled on the top of the bottom plate 7, and then the staff installs the cover 2 on the top of the base 1 under the action of the positioning guide column. At this time, the cover 2 itself will squeeze the plastic part 9, so that the bottom plate 7 moves downward. An array of plug rods 12 are connected to the bottom of the bottom plate 7, and splints 8 corresponding to the plug rods 12 are symmetrically provided in the horizontal direction in the groove 10, wherein one end of the splint 8 is elastically connected to the guide column 11, and a socket 14 for inserting the plug rod 12 is provided on the guide column 11. Under normal conditions, the plug rod 12 is inserted into the inside of the socket 14, and one end of the guide column 11 is connected through an elastic component. At this time, the elastic component is in a compressed state. When the bottom plate 7 drives the plug rod 12 to move downward, When the screw 5 is inserted into the fixing hole 14, the fixing hole 14 is tightened, and the fixing hole 14 is tightened, so that the fixing hole 14 is tightened and the fixing hole 14 is tightened.

[0039] See also Figure 4 The bottom of the socket 14 is open, which makes it easier for the rod 12 to be stably inserted into the socket 14 and plays a certain guiding role. The outer wall of the rod 12 and the inner wall of the socket 14 are smooth, which reduces the friction between the rod 12 and the socket 14, making it easier for the rod 12 to slide out of the socket 14.

[0040] See also Figure 2 and Figure 3 An array of micro-protrusions is provided on the top of the bottom plate 7. The micro-protrusions are convenient for increasing the sliding friction between the bottom plate 7 and the plastic part 9, preventing the plastic part 9 from shifting in position under slight external vibrations. A protective cover is provided on the inner side of the splint 8. The setting of the protective cover prevents the splint 8 from directly contacting the outer wall of the plastic part 9, further preventing the splint 8 from causing wear on the outer wall of the plastic part 9 during the assembly process. Example 2

[0041] like Figure 3 The illustrated assembly jig for plastic parts has an overall structure similar to that of Example 1, wherein the hardware positioning groove 3 is arranged in a trapezoidal shape as a whole. Under the action of the hardware positioning groove 3, it is convenient to determine the direction and positioning through the trapezoidal hole. The specific shape of the hardware positioning groove 3 can be changed by the hardware 6, which is convenient for the staff to further improve the positioning efficiency of the hardware 6 itself during subsequent installation.

[0042] The working principle of the present invention is as follows: when in use, the plastic part 9 to be assembled is placed on the bottom plate 7 in the groove 10, and then the cover 2 is covered on the top of the base 1 through the positioning guide column. At this time, the cover 2 will squeeze the plastic part 9, so that the bottom plate 7 at the bottom of the plastic part 9 moves downward. At this time, the bottom plate 7 will drive the insertion rod 12 to slide downward, thereby causing one end of the insertion rod 12 to slide out of the insertion hole 14. Under the action of the elastic component, the guide column 11 drives the splint 8 to slide to one side and position and clamp the plastic part 9. In this process, the stability of the plastic part 9 in the groove 10 is guaranteed during the subsequent assembly process. At the same time, a hardware positioning groove 3 is provided on the top of the cover 2, wherein the hardware positioning groove 3 makes the through hole on the hardware 6 and the embedded nut 13 in the same vertical direction. In this process, it is ensured that no tilting or misalignment occurs during the twisting of the screw 5.
