Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a segmented trimming fixture for a multi-side gate tailgate inner panel. Background Technology

[0002] As a complex, large, thin-walled component, the injection molding process for automotive tailgate inner panels places stringent requirements on gate design and subsequent processing. For long glass fiber (PP + glass fiber) tailgate inner panels, the main gate types currently include point gates and side gates. For products where the structure allows, point gates are typically used in non-appearance areas. The automatic fracture characteristics of point gates can significantly reduce post-processing time and effectively prevent the melt from severely eroding the glass fiber.

[0003] However, due to the complex geometry and mounting point locations of the tailgate inner panel, some tailgate inner panels cannot provide sufficient space or structural support for the proper arrangement of point gates. Therefore, side gates are often used instead. After demolding, side gates often form large, irregularly shaped stubs that are firmly connected to the body. Currently, the main methods for handling the stubs at the side gates are manual trimming or machine milling. Manual trimming has low precision and low production efficiency, making it unsuitable for high-volume, high-cycle tailgate inner panel production. Machine milling, on the other hand, generates a lot of shavings, which is also unsuitable for high-volume, high-cycle tailgate production. Furthermore, since different areas of the tailgate inner panel have different trimming requirements, neither manual trimming nor machine milling can provide targeted trimming for side gates in different areas with different requirements.

[0004] Therefore, a new type of segmented trimming fixture is urgently needed for tailgate inner panels with multiple side gates. Utility Model Content

In order to enhance the stability of the movable frame 3 when sliding, the base 1 can be provided with multiple slide rails 11.

[0081] The base pulling unit 4 in this embodiment includes at least one pulling cylinder 41. The cylinder body of the pulling cylinder 41 is disposed on the base 1. The end of the telescopic rod of the pulling cylinder 41 is connected to the movable frame 3, thereby driving the movable frame 3 to slide on the slide rail 11 for installing the tailgate inner panel 10.

[0082] like Figure 4-5 As shown, the movable frame 3 of this embodiment is provided with a first positioning plate 32, a second positioning plate 33, a third positioning plate 34, and a fourth positioning plate 35 from bottom to top.

The positioning plates are all specifically designed with numerous hollow areas according to the shape and position of other components within the fixture, facilitating the installation and operation of other components.

[0083] Example 3:

[0084] This embodiment provides a segmented trimming fixture for the inner panel of a multi-side gate tailgate. The trimming fixture of this embodiment includes a base 1, a fixed frame 2, a movable frame 3, a base pulling unit 4, a clamping unit 5, a pneumatic trimming unit 6, a pulling trimming unit 7, a pneumatic grinding unit 8, and a vibration cutting unit 9.

[0085] The difference from Example 1 is that, as Figure 6As shown, the clamping unit 5 in this embodiment includes a clamping drive cylinder 51, a clamping arm 52, a pressing member 53, a hinged connecting piece 55, and an auxiliary positioning block 54. Specifically, the clamping arm 52 is hinged to the end of the telescopic rod of the clamping drive cylinder 51, and the hinged connecting piece 55 is hinged to both the clamping arm 52 and the cylinder body of the clamping drive cylinder 51. When the telescopic rod of the clamping drive cylinder 51 retracts, the clamping arm 52 is in an open state, facilitating the insertion of the tailgate inner panel 10; when the telescopic rod of the clamping drive cylinder 51 extends, the clamping arm 52 is pulled inward under the restraint of the hinged connecting piece 55, so that the pressing member 53 at the top of the clamping arm 52 presses the tailgate inner panel 10 against the auxiliary positioning block 54.

[0086] In this embodiment, the clamping arm 52 can also be specially designed according to the shape and structure of the tailgate inner panel 10, and a corresponding auxiliary positioning block 54 can be added for positioning and cooperation.

[0087] Example 4:

[0088] This embodiment provides a segmented trimming fixture for the inner panel of a multi-side gate tailgate. The trimming fixture of this embodiment includes a base 1, a fixed frame 2, a movable frame 3, a base pulling unit 4, a clamping unit 5, a pneumatic trimming unit 6, a pulling trimming unit 7, a pneumatic grinding unit 8, and a vibration cutting unit 9.

[0089] The difference from Example 1 is that, as Figure 7 As shown, the pneumatic trimming unit 6 in this embodiment includes a first motion cylinder 61 and a pneumatic shear 62 disposed at the telescopic end of the motion cylinder 61. The pneumatic shear 62 is used to trim the side gates that are difficult to bend evenly, so that their residual height is controlled within 0-0.5mm.

Therefore, a vibration cutting method with less spray and higher efficiency is adopted.

[0093] In this embodiment, the base pulling unit 4, clamping unit 5, pneumatic trimming unit 6, pulling trimming unit 7, pneumatic grinding unit 8, and vibration cutting unit 9 are all connected to the central control system to achieve automated trimming of more than 10 areas of the tailgate inner panel.

From bottom to top, the movable frame 3 of this embodiment is provided with a first positioning plate 32, a second positioning plate 33, a third positioning plate 34, and a fourth positioning plate 35. The clamping units 5 of this embodiment are distributed on any one or more of the aforementioned positioning plates, and each of the four positioning plates is provided with positioning blocks 36 for positioning with the tailgate inner panel 10, thereby enhancing the positioning, fit, and clamping fixation of the tailgate inner panel 10 with the trimming fixture in multiple ways.

[0098] In this embodiment, the base pulling unit 4 is disposed on the base 1 and is used to drive the movable frame 3 to slide on the base 1 or to drive the movable frame 3 to press tightly against the fixed frame 2. The base pulling unit 4 includes at least one pulling cylinder 41. The cylinder body of the pulling cylinder 41 is disposed on the base 1, and the end of the telescopic rod of the pulling cylinder 41 is connected to the movable frame 3, thereby driving the movable frame 3 to slide on the slide rail 11 for installing the tailgate inner panel 10.

[0099] At least one clamping unit 5 is provided in this embodiment for clamping the tailgate inner panel 10 to be trimmed. The clamping unit 5 includes a clamping drive cylinder 51, a clamping arm 52, a pressing member 53, a hinge connecting piece 55, and an auxiliary positioning block 54. Specifically, the clamping arm 52 is hinged to the end of the telescopic rod of the clamping drive cylinder 51, and the hinge connecting piece 55 is hinged to both the clamping arm 52 and the cylinder body of the clamping drive cylinder 51.

[0100] The pneumatic trimming unit 6, the pull trimming unit 7, the pneumatic grinding unit 8, and the vibration cutting unit 9 in this embodiment can perform zoned trimming of the side gates in different areas of the tailgate inner panel 10.

[0101] In this embodiment, at least one pneumatic trimming unit 6 is provided for trimming the side gates on the tailgate inner panel 10 that are difficult to bend evenly.

[0104] In this embodiment, the vibration cutting unit 9 is provided at least one side gate for trimming the latching area of ​​the tailgate inner panel 10. The vibration cutting unit 9 includes a third motion cylinder 91, a Z-axis drive motor 92, a second connecting arm 93, and a vibration cutter 94.

The second connecting arm 93 is connected to the output shaft of the Z-axis drive motor 92 and can move up and down along the Z-axis as the output shaft rotates. The vibration cutter 94 is clamped at the end of the second connecting arm 93. The 4.5mm feed piece of the latching area of ​​the tailgate inner panel 10 is vibrated and cut using a vibration cutting method. Since the PP+LGF40 material used in the latching area of ​​the tailgate inner panel 10 has high strength, it cannot be trimmed using conventional pneumatic shears and rotary cutting methods. Therefore, a vibration cutting method with less spray and higher efficiency is adopted.

[0105] In this embodiment, the base pulling unit 4, clamping unit 5, pneumatic trimming unit 6, pulling trimming unit 7, pneumatic grinding unit 8, and vibration cutting unit 9 are all connected to the central control system to achieve automated trimming of more than 10 areas of the tailgate inner panel. The central control system can be a conventional industrial PLC control system, which can be programmed to achieve different material processing sequences or processing parameters.

[0106] Based on the above structure, the working principle of the tailgate inner panel trimming fixture in this embodiment is as follows:

[0107] (1) The tailgate inner panel 10 to be trimmed is pressed onto the movable frame 3 by the clamping unit 5, and the movable frame 3 is pressed onto the fixed frame 2 by the base pulling unit 4.

[0108] Specifically, the tailgate inner panel 10 is first placed on each of the positioning blocks 36 of the positioning plates (32, 33, 34, 35). Then, the clamping unit 5 is activated, the extension rod of the clamping drive cylinder 51 extends, thereby driving the clamping arm 52 to rotate and pressing the tailgate inner panel 10 onto the auxiliary positioning block 54 through the pressing member 53.

[0109] Activate the pull cylinder 41 to drive the moving frame 3 to move along the slide rail 11 toward the fixed frame 2 and press it against the fixed frame 2.

[0110] (2) The side gates on the inner panel 10 of the tailgate that are difficult to bend are trimmed by the pneumatic trimming unit 6.

[0111] Specifically, the first motion cylinder 61 takes in air, driving the pneumatic shears 62 to approach and trim the side gate that is difficult to bend, so that its residual height is controlled at 0-0.5mm.

[0112] (3) By pulling the trimming unit 7, the material head at the side gate of the tailgate inner panel 10, which is easy to be broken, is pulled off in the X direction.

[0113] Specifically, air is introduced into the X-direction drag cylinder 71, driving the clamping cylinder 72 at the telescopic end to approach the side gate. The flexible clamp of the clamping cylinder 72 is used to trim the side gate into a neatly breakable shape. By using the flexible clamp to trim the side gate into a neatly breakable shape, the cylinder and clamp simulate the operation of manually breaking the side gate, thereby achieving highly efficient trimming of the tailgate inner panel 10.

[0114] (4) The pneumatic grinding unit 8 grinds the broken gate of the tailgate inner panel 10 after it is pulled into place.

[0115] Specifically, the movable frame 3 is pressed tightly onto the fixed frame 2 by the base pulling unit 4, and the tailgate inner panel 10 to be trimmed is pressed onto the movable frame 3 by the clamping unit 5. The pneumatic file 82 is attached to the tailgate inner panel 10 with the gate pulled off by the first connecting arm 81. The gate of the glass area with high precision requirements (after automatic inference) is automatically polished by the trimming method of the pneumatic file 82.

[0116] (5) The vibration cutting unit 9 trims the side gate of the locking area on the inner panel 10 of the tailgate.

[0117] Specifically, the third motion cylinder 91 takes in air, driving the Z-axis drive motor 92 to move horizontally, and through the cooperation of the Z-axis drive motor 92 and the second connecting arm 93, drives the vibratory cutter 94 to move along the Z-axis and approach the side gate. Finally, the vibratory cutter 94 performs vibration cutting on the 4.5mm feed piece of the locking area of ​​the tailgate inner panel 10.

[0118] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort.
