The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] See alsoFigure 1 , Figure 2 , Figure 5 and Figure 6 A plastic hole pressing metal sleeve jig comprises: a base 100, wherein the middle part of the base 100 has a limiting space, and positioning columns 300 corresponding to the plastic holes 11 of the plastic product 10 are respectively arranged on both sides of the base 100, and the bottom of the positioning column 300 has an elastic member (not shown in the figure); a pressing plate 200, wherein the pressing plate 200 is located above the base 100 and is provided with a pressing sleeve 210 corresponding to the positioning column 300.

[0033] Specifically, when the present embodiment is operated, the base 100 is mounted on the platform of the punching machine, and the pressing plate 200 is installed and connected with the pressing part of the punching machine. After the jig is installed on the punching machine, the plastic product 10 is placed in the limited space of the base 100 for limiting, and the plastic holes 11 on both sides of the plastic product 10 are respectively inserted into the positioning posts 300, and then the metal sleeves 20 are sleeved on each positioning post 300. At this time, the punching machine is started again, and the pressing part of the punching machine will drive the pressing plate 20 to move downward. While the pressing plate 20 moves downward, the pressing sleeve 210 will press the metal sleeve 20. When the metal sleeve 20 is pressed, it will act on the positioning post 300, so that the positioning post 300 moves downward, and the positioning post 300 The elastic part at the bottom is squeezed, and the elastic part can be a compression spring. When the positioning column 300 moves downward, the metal sleeve 20 will be pressed into the plastic hole 11, so as to realize the press-fitting of the metal sleeve 20, making the press-fitting process of the metal sleeve 20 simple and convenient, and the simultaneous press-fitting of multiple metal sleeves 20 can be realized through the jig, thereby improving the press-fitting efficiency of the metal sleeve 20, and making the metal sleeve 20 evenly stressed during press-fitting, ensuring the press-fitting quality of the metal sleeve 20, and avoiding the plastic hole 11 of the plastic product 10 from being cracked during operation; after the metal sleeve 20 is pressed in, the pressing plate 200 moves upward to reset, and the positioning column 300 is reset under the action of the elastic part, and the plastic product 10 can be removed at this time, and the next plastic product 10 can be press-fitted, and the cycle is repeated.

[0034] Of course, in order to press the metal sleeve 20 into the plastic hole 11 of the plastic product 10, the outer diameter of the metal sleeve 20 will be larger than the inner diameter of the plastic hole 11, and the side wall of the metal sleeve 20 has an opening 21. When the metal sleeve 20 is press-fitted, the metal sleeve 20 is axially pressed by the pressing sleeve 210, and the metal sleeve 20 is radially squeezed by the inner diameter of the plastic hole 11, so that the opening 21 of the metal sleeve 20 becomes smaller, so as to facilitate press-fitting it into the plastic hole 11. After being pressed in, the opening 21 of the metal sleeve 20 expands outward under its own recovery, so that it is tightly fitted in the plastic hole 11.

[0035] See also Figure 3, in order to limit the plastic product 10, therefore, the base 100 in this embodiment includes an integrally formed limiting portion 110 and a pressing sleeve portion 120, and pressing sleeve portions 120 are provided on both sides of the limiting portion 110, and the height of the pressing sleeve portion 120 is higher than that of the limiting portion 110, so that the base 100 forms a concave shape, and the protruding side walls of the pressing sleeve portion 120 are limiting walls 121. Through the enclosure of the limiting walls 121 on both sides and the limiting portion 110, a limiting space is formed. When press-fitting the metal sleeve 20, the plastic product 10 can be directly placed in the limiting space for limiting; at the same time, in order to ensure the limitation of the plastic product 10, the distance between the two limiting walls 121 is adapted to the size of the plastic product 10, and the overall length of the plastic product 10 can be limited and fixed by the two limiting walls 121.

[0036] At the same time, in order to better limit the plastic product 10, several limiting grooves 111 are further provided on the limiting portion 110. Since the bottom of the plastic product 10 has protruding parts, the protruding parts will cooperate with the limiting grooves 111. When the plastic product 10 is placed in the limiting space, the protruding parts at the bottom of the plastic product 10 will be placed in the limiting grooves 111. Through the limiting grooves 111 and the protruding parts at the bottom of the plastic product 10, the plastic product 10 can be better limited, so as to avoid the displacement of the plastic product 10 when pressing the metal sleeve 20.

[0037] In addition, in order to install the positioning column 300, in this embodiment, a pressing sleeve hole 122 is provided on the pressing sleeve portion 120. When the positioning column 300 is assembled, it will penetrate upward from the bottom of the pressing sleeve hole 122. After penetration, an elastic member is arranged at the bottom of the positioning column 300 for abutment, and the other end of the elastic member 300 can abut against the plug of the pressing sleeve hole 122 or cooperate with the stamping machine platform, and the positioning column 300 can move along the pressing sleeve hole 122 through the pressing sleeve 210 and the elastic member.

[0038] Please refer to Figure 4 , in order to facilitate the pressing of the metal sleeve 20 into the plastic hole 11 of the plastic product 10, therefore, the positioning column 300 in this embodiment includes a positioning section 310, a movable section 320 and a limiting section 330 which are connected in sequence from top to bottom. The diameters of the positioning section 310, the movable section 320 and the limiting section 330 increase in sequence. An abutting surface 321 is formed at the top of the movable section 320. The diameter of the limiting section 330 is larger than the inner diameter of the pressing sleeve hole 122, which can prevent the elastic member from pushing the positioning column 300 out of the pressing sleeve hole 122. The diameter of the movable section 320 is adapted to the inner diameter of the pressing sleeve hole 122, which can facilitate the up and down movement of the movable section 320 along the pressing sleeve hole 122. The diameter of the positioning section 310 is matched with the inner diameter of the metal sleeve 20, which can prevent the metal sleeve 20 from shifting during press-fitting and avoid cracking the plastic hole 11.

[0039] In the initial state, the movable section 320 of the positioning column 300 can be protruded from the top surface of the pressing sleeve hole 122 by the elastic member. When the plastic product 10 is limited, its plastic hole 11 will be inserted into the movable section 320 of the positioning column 300. At this time, the metal sleeve 20 is inserted from the top of the positioning section 310. The metal sleeve 20 is sleeved on the positioning section 310, and its bottom surface is placed on the abutment surface 321 of the movable section 320. When the pressing plate 200 moves downward, the pressing plate 20 0 will act on the top surface of the metal sleeve 20 and press it. When the metal sleeve 20 is pressed, it will act on the abutment surface 321 of the movable section 320, so that the movable section 320 moves downward along the pressing sleeve hole 122. When the movable section 320 moves downward, the pressing sleeve 210 will press the metal sleeve 20 into the plastic hole 11, thereby realizing the press-fitting of the metal sleeve 20 and making the metal sleeve 20 evenly stressed during press-fitting, thereby ensuring its press-fitting quality.

[0040] In order to enable the pressing sleeve 210 to easily press the metal sleeve 20 into the plastic hole 11, in this embodiment, the inner hole diameter of the pressing sleeve 210 needs to match the outer diameter of the positioning section 310 of the positioning column 300, so that when the pressing sleeve 210 presses the metal sleeve 20, the positioning section 310 can be inserted into the inner hole of the pressing sleeve 210, so that the pressing sleeve 210 can always press the metal sleeve 20 into the plastic hole 11 of the plastic product 10.

[0041] Finally, in order to facilitate the insertion of the plastic hole 11 and the metal sleeve 20 of the plastic product 10 into the positioning column 300, the top of the positioning section 310 has a chamfer 311, and the chamfer 311 can be a rounded corner. The rounded chamfer 311 can facilitate the installation of the plastic hole 11 and the metal sleeve 20.

[0042] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Any technician in the industry can smoothly implement the utility model according to the drawings shown in the specification and the above description; however, any equivalent changes, modifications and evolutions made by any technician familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the scope of protection of the technical solution of the utility model.
