[0031] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0032] Example 1

[0033] In a typical implementation of the present invention, Figure 1 As shown, an automatic workpiece pressing device is provided, including: a transfer platform, a shell fixture assembly is provided on one side of the transfer platform for clamping the shell 5, so as to achieve stable clamping of the shell 5, and at the same time facilitate the operation of the workpiece 4 in different workstations during the production process, and avoid interference between the workpiece 4 and other parts of the device during installation and disassembly.

[0034] A pressing assembly is provided on the side of the transfer platform opposite to the housing fixture assembly, and two parallel guide rails 12 are provided on the transfer platform at the same time. The guide rails 12 have a certain spacing therebetween, and are slidably connected to the clamping jaw assembly and the push rod assembly 13 respectively. The clamping jaw assembly and the push rod assembly 13 are arranged side by side on the transfer platform, so that the clamping jaw assembly and the push rod assembly 13 can respectively slide in the Y direction through the guide rails 12, and the clamping jaw assembly and the push rod assembly 13 can realize movement in the X direction through the drive of the transfer platform.

[0035] The shell 5 corresponding to the workpiece 4 is placed on the shell placement fixture 6, and the workpiece 4 is clamped by the clamping claw assembly. The workpiece 4 is pressed into the shell 5 once by the pressing assembly, but not completely. After the clamped workpiece 4 is withdrawn, it is pressed into the shell 5 for the second time by the push rod assembly 13.

[0036] It is understandable that during the two pressing processes respectively performed above, the connection positions of the pressing assembly, the clamping jaw assembly, the push rod assembly 13, and the housing placement fixture 6 are such that the workpiece 4 and the housing 5 always remain aligned during the pressing.

[0037] The transfer platform includes a transfer cylinder 11, which is arranged on a transfer cylinder mounting plate 9. The bottom surface of the transfer cylinder mounting plate 9 is fixedly connected to a column 10, and the other end of the column 10 is fixedly connected to a bottom plate 8, and the bottom plate 8 is placed on a working plane. The column 10 is vertically connected to the bottom plate 8 and the transfer cylinder mounting plate 9, and the connection between the above structures includes but is not limited to bolt connection to maintain the stability of the entire device during operation.

[0038] The transfer cylinder 11 is connected to the transfer plate 16, and the transfer plate 16 is provided with two parallel guide rails 12, which are respectively slidably connected to the clamping jaw assembly and the push rod assembly 13. The transfer cylinder 11 drives the transfer plate 16 to realize the movement of the clamping jaw assembly and the push rod assembly 13 in the X direction. It can be understood that the movement of the clamping jaw assembly and the push rod assembly 13 in the X direction is synchronized with the transfer platform.

[0039] The housing jig assembly includes a housing placement jig 6, and a rotary clamping cylinder 7 is provided on one side of the housing placement jig 6. The rotary clamping cylinder 7 drives the pressing plate to move and rotate, and presses the housing 5 on the housing placement jig 6. The housing placement jig 6 can move up and down by rotating the clamping cylinder 7, thereby driving the housing 5 to move up and down, so as to adapt to the assembly of the workpiece 4 and the housing 5 under various conditions.

[0040] The pressing assembly includes a pressing electric cylinder 1, which is fixed on the transfer cylinder mounting plate 9. The output end of the pressing electric cylinder 1 is connected to the pressure head, and the side of the pressure head facing the transfer platform is an arc structure, which avoids interference during the pressing process and provides stable pushing pressure.

[0041] like Figure 2 As shown, the clamp assembly includes a clamp cylinder 2, which is arranged on a clamp assembly mounting base. The clamp assembly mounting base can slide on a guide rail 12. The output end of the clamp cylinder 2 is connected to a plurality of clamps 3, and the plurality of clamps 3 are distributed in a circular array at the output end of the clamp cylinder 2, so as to achieve stable clamping of the workpiece 4 and ensure accurate positioning with the housing 5 during pressing, so as to avoid bending and breakage of the workpiece 5 caused by clamping deviation during pressing.

[0042] The push rod assembly 13 includes a push rod, which is arranged on a push rod mounting seat. The push rod mounting seat can slide on the guide rail 12 to realize the pressing of the workpiece 4, and a protrusion is provided at one end of the mounting seat facing the outer shell for placing the jig 6. The protrusion is fixedly connected to the push rod. While the connection is stable, it avoids interference between the push rod assembly 13 and other parts of the device during the pressing of the workpiece 4.

[0043] It is understandable that the structure of the push rod includes but is not limited to a rectangle, and the specific structure can be set according to the workpiece 4 to be pushed.

[0044] The push rod assembly 13 is also provided with a pressure sensor 15 to detect the pressing pressure to ensure the stability of the press-in assembly of the workpiece 4 and avoid damage to the workpiece 4 due to excessive pressure during press-in and assembly failure due to insufficient pressure.

[0045] The sliding direction Y of the clamping jaw assembly and the push rod assembly 13 is perpendicular to the movement direction X of the transfer platform. The above structure realizes automatic clamping and pressing of the workpiece 4 through movement coordination in the X and Y directions, thereby avoiding interference and improving assembly efficiency.

[0046] The clamping jaw assembly and the push rod assembly 13 are also connected to a tension spring 14 to cooperate with the movement and pressing of the entire workpiece 4. During the movement and pressing process, the clamping jaw assembly and the push rod assembly 13 can be pulled back to their original positions by the tension spring 14 to ensure the stable progress of the process and avoid the situation where the clamping jaw assembly and the push rod assembly 13 fail to return to their proper positions, causing interference with the housing 5 or other parts of the device during the assembly of the workpiece 4, thereby damaging the workpiece 4.

[0047] The working principle of the automatic workpiece pressing device of the utility model:

[0048] like Figure 3 As shown, in the automated production process, the shell 5 is transferred from the previous station to the shell placement jig 6, the rotating clamping cylinder 7 descends to clamp the shell 5, the transfer cylinder 11 moves right, the clamping jaw assembly clamps the workpiece 5 from the previous station, and the transfer cylinder 11 moves left back to the pressing position. During this process, the workpiece 4 is aligned with the corresponding shell 5, and then the pressing electric cylinder 1 pushes the clamping jaw assembly to press in, so that the workpiece 4 moves to the specified position, so that the workpiece 4 enters a part of the shell 5;

[0049] like Figure 4 As shown, the pressing electric cylinder 1 then retreats, the clamping jaw assembly is pulled back to its original position by the tension spring 14, the transfer cylinder 11 moves to the right, and the push rod assembly 13 moves to the pressing position. At this time, the push rod assembly 13 is aligned with the workpiece 4, and the pressing electric cylinder 1 pushes the push rod assembly 13 to press in, so that the workpiece 4 completely enters the housing 5. At the same time, the pressure sensor 15 detects the pressure. When the set standard value is reached, the assembly is judged to be qualified, the pressing electric cylinder 1 retreats, and the push rod assembly 13 is pulled back to its original position by the tension spring 14. The rotating clamping cylinder 7 makes the finished product after pressing rise and move it to the next station.

[0050] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
