For ordinary skilled persons in the art, the specific meanings of the above terms in the embodiments of the utility model can be understood according to specific circumstances.

[0026] In an embodiment of the utility model, as shown in Figures 1-6 A face cover press fitting machine with accurate positioning is provided, which comprises a workbench 1 and a base 2 arranged on the workbench 1. A mounting seat 3 is formed in the middle of the base 2 and used for mounting an assembly 10. The mounting seat 3 is provided with a plurality of stamping grooves 31. The assembly 10 comprises a metal face cover 101 and a plastic part 102 mounted at the bottom of the metal face cover 101. The metal face cover 101 extends towards the plastic part 102 and is provided with a plurality of mounting strips 103. The workbench 1 is provided with a plurality of first driving members 21 and a plurality of punch rods 22 around the base 2. The top surface of the punch rod 22 is provided with a guide groove 23. A sub-push rod 231 is arranged in the guide groove 23. The extension directions of the guide groove 23 and the sub-push rod 231 are the same as the extension direction of the punch rod 22. Each first driving member 21 is used for driving the corresponding punch rod 22 to push the corresponding mounting strip 103 into the corresponding stamping groove 31. The mounting strip 103 is pressed on the bottom surface of the plastic part 102 through the sub-push rod 231.

[0027] Further, the punch rod 22 and the sub-push rod 231 are provided with a buffer surface 24 on the side close to the mounting base 3, the buffer surface 24 comprises a vertical part 241 and an inclined surface 242, the inclined surface 242 is arranged on the top of the vertical part 241, and the inclined surface 242 is inclined from the top of the vertical part 241 to the direction away from the mounting base 3. The guide groove 23 is open outward through the inclined surface 242. The top of the sub-push rod 231 is higher than the top of the punch rod 22. Specifically, in the installation process, the punch rod 22 is driven by the first driving member 21 to move towards the stamping groove 31, at this time, the inclined surface 242 of the buffer surface 24 of the punch rod 22 extrudes the lower section of the mounting strip 103, so that the lower section of the mounting strip 103 is attached to the buffer surface 24 of the punch rod 22, and gradually makes the middle section of the mounting strip 103 slide into the guide groove 23, when the middle section of the mounting strip 103 contacts with the buffer surface 24 of the sub-push rod 231, the upper section of the mounting strip 103 is pushed to bend and deform towards the bottom of the plastic part 102, finally, the top of the sub-push rod 231 is attached to the plastic part 102 by sliding and extruding the mounting strip 103, in addition, the mounting strip 103 can be constrained by the guide groove 23 during the deformation process, and the deformation of the mounting strip 103 occurs along the extension direction of the guide groove 23, so that the bending effect of the mounting strip 103 is better, and the protruding angle at the connection between the mounting strip 103 and the metal cover 101 is avoided when the mounting strip 103 deforms to other directions, thereby improving the product quality and the yield.

[0028] Further, the fixing mechanism 4 for fixing the assembly 10 is further included, the workbench 1 is provided with a plurality of sliding grooves 11, the fixing mechanism 4 includes a plurality of clamps 41 and a second driving member 42 corresponding to each of the clamps 41 respectively, the second driving member 42 is used to push the clamp 41 to move in the sliding groove 11 towards or away from the mounting seat 3. The clamp 41 is provided with a limiting groove 411, a screw rod 412 is slidably arranged in the limiting groove 411, the screw rod 412 is vertically arranged on the bottom surface of the sliding groove 11, and the nut part of the screw rod 412 is limitedly and slidably matched with the top surface of the clamp 41. The top of each of the clamps 41 extends a pressing part 413 above the mounting seat 3, and the pressing part 413 is matched with the top surface of the mounting seat 3 to fix the assembly 10. Each of the sliding grooves 11 extends to the center of the mounting seat 3, and the extension direction of each of the sliding grooves 11 has a certain angle with the extension direction of an adjacent one of the punching grooves 31, so that the pressing part 413 is located above the punching groove 31 when the second driving member 42 pushes the clamp 41 to clamp the assembly 10. Specifically, when installing, the assembly 10 is placed on the mounting seat 3, the clamp 41 is driven by the second driving member 42 to move towards the mounting seat 3, and finally the pressing part 413 is completely pressed on the top edge of the assembly 10. In this process, the pressing part 413 gradually moves above the mounting seat 3 and moves above the punching groove 31, so that the pressing part 413 fixes the position of the assembly 10 corresponding to the punching groove 31, avoids displacement of the assembly 10 during punching operation, and realizes better processing quality. In addition, in the process of moving the clamp 41 by the second driving member 42, the top surface of the clamp 41 slides with the nut part of the screw rod 412, which limits the clamp 41 and avoids the clamp 41 from being raised upward, so that better clamping effect is realized.

[0029] Working principle: when in use, the assembly 10 is installed on the mounting seat 3, at this time the installation strip 103 of the metal surface cover 101 of the assembly 10 is located in the punching groove 31, the punch rod 22 is driven by the first driving member 21 to move into the punching groove 31, in this process, one end of the punch rod 22 first extrudes the bottom end of the installation strip 103, and makes the bottom end of the installation strip 103 bent, so that the middle segment of the installation strip 103 slides into and slides on the bottom wall of the guide groove 23, until the middle segment of the installation strip 103 is in contact with the auxiliary push rod 231 and is extruded and deformed by the auxiliary push rod 231, so that the upper segment of the installation strip 103 is bent and deformed towards the bottom of the plastic part 102, and finally the top surface of the auxiliary push rod 231 is in sliding extrusion with the installation strip 103 to realize the fixed fit with the bottom of the plastic part 102, so that good fixing effect is realized, and the phenomenon that the installation strip 103 is broken or the installation strip 103 cannot be fitted with the bottom of the plastic part 102 is avoided.

[0030] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
