The basic principles of the utility model, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the utility model.

It will be understood by those skilled in the art that in the disclosure of the specification, the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, which are merely for convenience in describing the utility model and to simplify the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus the terms are not to be construed as limiting the utility model.

A bending press-fitting mechanism according to a preferred embodiment of the present invention will be described in detail below with reference to fig. 1 to 5 of the specification. The bending press-fitting mechanism is used for bending and press-fitting a plurality of antennae 11 on the periphery of a workpiece 10, and comprises a mechanism body 20, a positioning element 30, a guide press-fitting mechanism 40 and a bending mechanism 50.

The positioning member 30 is fixedly disposed at an upper portion of the mechanism body 20, wherein the positioning member 30 is provided with a first clearance groove 31 corresponding to the antenna 11 of the workpiece 10. The positioning of the workpiece 10 is realized by inserting the antenna 11 around the workpiece 10 into the first avoiding groove 31 corresponding to the positioning element 30, and meanwhile, the first avoiding groove 31 can also provide a processing avoiding position for bending and press-fitting the antenna 11.

The guiding press-fitting mechanism 40 includes a guiding rod 41 correspondingly disposed below the first avoiding groove 31, wherein the guiding rod 41 is disposed on the mechanism body 20 in a manner of moving up and down synchronously, and a press head 42 is mounted on the upper portion of the guiding rod 41, so that the antenna 11 can be press-fitted synchronously from bottom to top after the antenna 11 is bent, and the antenna 11 is made to approach the bottom of the workpiece 10.

The bending mechanism 50 includes a bending rod 51 corresponding to the antenna 11 and a bending knife 52 disposed on the bending rod 51 and extending into the first avoiding groove 31, wherein the bending rod 51 is matched with the corresponding guide rod 41, so that when the guide rod 41 moves upwards, the corresponding bending rod 51 can be driven to drive the bending knife 52 to shift inwards, so as to bend the antenna 11, and after the antenna 11 is bent, the bending rod 51 and the bending knife 52 can be reset by the continuous upward movement of the guide rod 41, so that the press-fitting of the antenna 11 is realized by the continuously-rising press head 42.

In other words, during the upward movement of the guide rod 41, the guide rod 41 drives the bending rod 51 in a manner such that the folding blade 52, which is disposed on the bending rod 51 and extends into the first avoiding groove 31, is synchronously bent inward, thereby bending the antenna 11 corresponding to the first avoiding groove 31, then the guide rod 41 is continuously driven to move upward, so that the bending rod 51 and the folding blade 52 are reset, and finally the antenna 11 is directly pressed upward by the pressing head 42 which is continuously lifted, so as to be close to the bottom of the workpiece 10. The manner in which the guide rod 41 drives the folding blade 52 to shift inward and return outward will be described in detail later.

In the process of machining the workpiece 10 having the antenna 11 on the periphery, it is often necessary to fix the workpiece 10 to a machine. For example, in the process of bending and press-fitting the label of the steering wheel of the automobile, the antenna of the label needs to be bent and press-fitted on the steering wheel of the automobile. That is, the installed equipment may be different for the machining of different workpieces, or for the machining of workpieces of different specifications. In order to facilitate the fixing of the device for installing the workpiece 10, as a preferred embodiment of the present application, the bending press-fitting mechanism further includes a profile fixing plate 60, wherein the profile fixing plate 60 is fixedly disposed on the mechanism body 20 and located below the positioning element 30. The profiling fixing plate 60 is provided with a second avoiding groove 61 to communicate with the corresponding first avoiding groove 31 in the vertical direction, wherein the folding knife 52 movably penetrates through the second avoiding groove 61. In addition, the profile modeling fixing plate 60 is also provided with a plurality of mounting holes so as to facilitate the installation and the fixation of equipment. Therefore, when different workpieces 10 are machined, only the corresponding copying fixing plate 60 needs to be replaced, so that the cost can be effectively saved, and the production efficiency can be improved.

It is worth mentioning that, in the specific arrangement mode that the guide rod 41 can move up and down synchronously, one possible implementation mode is: the guiding press-fitting mechanism further includes a lifting drive device 70 to drive the guide rods 41 in a directional and synchronous manner. The lifting driving device 70 includes a first driving element (not shown), a sliding bottom plate 71, and a plurality of guiding columns 72 spaced along the circumference of the sliding bottom plate 71. The guide post 72 is fixedly provided to a lower portion of the mechanism body 20 in a vertical direction. The sliding bottom plate 71 is fixed to the bottom end of the guide rod 41 in the horizontal direction, and is slidably fitted over the guide post 72. The first driving element is disposed below the sliding bottom plate 71 to drive the guide rod 41 to move up and down synchronously, wherein the first driving element is preferably implemented as an air cylinder. The sliding bottom plate 71 is driven to move up and down by the expansion and contraction of the air cylinder, so that the guide rod 41 fixedly arranged on the top surface of the sliding bottom plate 71 is driven to move up and down along the extending direction of the guide post 72.

It should be noted that, after the work piece is machined, although the sliding bottom plate 71 can be automatically lowered and reset by the self weight of the sliding bottom plate 71, in order to further improve the working efficiency, the guide posts 72 are respectively sleeved with a first elastic member 73, wherein the first elastic member 73 is disposed above the sliding bottom plate 71 in a compressed manner, so that after the first driving element is reset, the sliding bottom plate 71 can be rapidly lowered and reset by the rebounding action of the first elastic member 73, so as to rapidly machine the next work piece 10, wherein the first elastic member 73 is preferably implemented as a spring.

In addition, the guide post 72 is further sleeved with a guide sliding sleeve 74, wherein the guide sliding sleeve 74 is embedded between the sliding bottom plate 71 and the guide post 72 to provide guidance for the up-and-down movement of the sliding bottom plate 71, effectively reduce the friction force between the sliding bottom plate 71 and the guide post 72, and improve the working efficiency and the service life of the bending press-fitting mechanism. The guide sliding sleeve 74 is preferably implemented as a linear bearing, which performs point contact friction with the guide post 72 through a ball or a roller inside the bearing, and is particularly suitable for high-speed linear movement of the sliding bottom plate 71 on the guide post 72, and the friction resistance is small, the precision is high, and the movement is rapid.

As for the way of driving the folding knife 52 to shift inward and return outward by the guide rod 41, one possible implementation is as follows: the mechanism body 20 is further fixedly provided with a plurality of mounting blocks 21, wherein the inner sides of the mounting blocks 21 are provided with hinge grooves 22 for the lower parts of the bending rods 51 to be hinged to the mounting blocks 21, so that the upper parts and the lower ends of the bending rods 51 can rotate by taking the hinge points as rotation axes. Specifically, when the lower end of the bending bar 51 moves outward, the upper portion of the bending bar 51 can be shifted inward in synchronization. Similarly, when the lower end of the bending rod 51 moves inward, the upper portion of the bending rod 51 can be shifted outward in synchronization. The mounting block 21 is further provided with a second elastic member 23 below the hinge slot 22, wherein the second elastic member 23 is compressed between the bending bar 51 and the mounting block 21, wherein the second elastic member 23 is preferably implemented as a spring.

The outer side of the guide rod 41 is provided with an arc-shaped convex structure 411. The protruding structure 411 is engaged with the bottom end of the bending bar 51. When the guide rod 41 moves upwards, the bottom end of the bending rod 51 moves outwards by the protrusion 411 pushing the bending rod 51 to compress the second elastic part 23. Under the hinge action of the bending rod 51 and the mounting block 21, the folding blade 52 provided to the bending rod 51 is correspondingly shifted inward in the first avoiding groove 31, thereby bending the corresponding antenna 11. When the guide rod 41 moves upwards continuously to enable the bending rod 51 to cross the convex structure 411, under the rebounding action of the second elastic element 23, the bending rod 51 automatically resets to enable the folding knife 52 to reset to be away from the antenna 11, so that a press-fitting position is provided for the press head 42 which is pushed continuously due to the fact that the guide rod 41 moves upwards continuously, and press-fitting of the bent antenna 11 is completed.

The bending press-fitting mechanism provided by the application synchronously drives the guide rod 41 to move up and down through the sliding base plate 71, then drives the bending mechanism 20 to bend the corresponding antenna 11 in a mechanical transmission mode through the convex structure 411, after the antenna 11 is bent, the bending mechanism 50 automatically resets, and finally, the bent antenna 11 is press-fitted through the continuous upward movement of the guide rod 41. Therefore, the bending press-fitting mechanism is driven only by an external power source (a first driving element), and most of the bending press-fitting mechanism realizes integral processing of bending and press-fitting the workpiece 10 by means of a smart transmission design structure, so that energy can be effectively saved, and the processing efficiency is improved. Meanwhile, based on the operation mode of mechanical transmission, the manufacturing cost is low, and the maintenance and the repair at the later stage are more convenient.

In a possible embodiment, the bottom end of the bending rod 51 is provided with a rotating element 511 cooperating with the protruding structure 411, wherein the rotating element 511 is preferably embodied as a bearing. Through the rotation of the bearing relative to the convex structure 411, the bottom end of the bending rod 51 can be driven by the convex structure 411 more flexibly to move outwards, and meanwhile, the friction force between the bending rod 51 and the guide rod 41 can be effectively reduced.

Preferably, a rod-shaped mounting portion 421 is integrally provided at a lower portion of the pressing head 42, wherein the mounting portion 421 is movably provided to the guide rod 41 along an extending direction of the guide rod 41, so that the height of the pressing head 42 can be flexibly adjusted to be suitable for press-fitting workpieces 10 of different heights. Specifically, the inner side of the guide rod 41 is correspondingly provided with a limiting groove 412 along the vertical direction to accommodate the mounting portion 421. The mounting portion 421 and the limiting groove 412 are both provided with a plurality of mounting screw holes 422 along the vertical direction. The mounting portion 421 flexibly adjusts the total length of the guide rod 41 and the pressure head 42, i.e., the height of the pressure head 42, by being screwed at different positions in the limit groove 412 of the guide rod 41. In a specific arrangement, the pressing head 42 is preferably disposed along the extending direction of the guide rod 41 and as close to the inner side of the guide rod 41 as possible to avoid interference with the offset of the folding blade 52.

In one possible embodiment, the folding blade 52 is movably arranged on the folding bar 51 in the direction of extension of the folding bar 51, so that the folding of different workpieces 10 and/or different tentacles 11 is adapted by the movement of the folding blade 52, wherein the specific arrangement of the folding blade 52 that is movable in the folding bar 51 can be referred to the arrangement of the pressure head 42 that is movable in the guide bar 41.

In some cases, the press-fitting force of the ram 42 against the antenna 11 can be cancelled out by only the self-weight of the workpiece 10. However, in some cases, when the self-weight of the workpiece 10 is difficult to effectively counteract the press-fitting force of the ram 42 on the antenna 11, an additional force needs to be applied above the workpiece 10. Therefore, in a possible embodiment, the bending press-fitting mechanism further includes a pressing element (not shown), wherein the pressing element is preferably implemented as a cylinder, wherein the pressing element is disposed above the mechanism body 20 to press the workpiece 10 above, so as to prevent the workpiece 10 from moving during the press-fitting process, and also prevent the workpiece 10 from moving during the bending process, which affects the press-fitting and bending quality.

It should be noted that the terms "first and second" in the present invention are used for descriptive purposes only, do not denote any order, are not to be construed as indicating or implying any relative importance, and are to be interpreted as names.

The objects of the utility model have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
