Description

Technical Field

[0001] This utility model relates to the technical field of automotive interior parts processing equipment, specifically a flanging device for automotive interior covering parts. Background Technology

[0002] As the demands for automotive performance, appearance, and safety continue to increase, the requirements for automotive interiors are also constantly rising. Nowadays, automotive interiors generally use wrapping parts to enhance aesthetics, comfort, and luxury. When processing automotive interior wrapping parts, it is necessary to perform a flanging operation on their edges.

[0003] A Chinese patent describes a novel flanging device for automotive interior trim panels (patent number: CN220973392U). This device includes a support frame with multiple flanging mechanisms on its top surface. Each flanging mechanism includes a drive assembly, which is vertically mounted on the top surface of the support frame. A second drive assembly is mounted on the output shaft of the drive assembly, and the second flanging mechanism is located on the top surface of the support frame. This device automates the flanging of automotive interior trim panels, replacing manual labor and reducing workload. However, the device has a relatively simple structure, relying solely on a cylinder to push a flanging plate. Since the flanging plate is not fixed to the edge of the automotive interior trim panel, the edge of the panel is prone to detaching from the flanging plate during the flanging process, affecting the stability of the flanging process.

[0023] Please see Figures 1-4 In this practical embodiment, a flanging device for automotive interior trim is provided. The device consists of four sets, with the four sets of flanging mechanisms arranged around the periphery of the automotive interior trim. This device only takes one set of flanging mechanisms as an example, as detailed in the background art document, which is prior art and will not be explained further here.

[0024] This embodiment includes a base plate shell 1 and a fixing plate 2. The fixing plate 2 is vertically disposed at one end of the top surface of the base plate shell 1. The base plate shell 1 is provided with a flipping mechanism. The upper end of the fixing plate 2 is hinged to a connecting plate 3. The upper end of the connecting plate 3 is fixedly connected to a flange plate 4. The fixing plate 2, the connecting plate 3, and the flange plate 4 are on the same vertical plane from bottom to top. One end of the flipping mechanism is hinged to the flange plate 4. A pressure-relieving mechanism is provided on one side of the flange plate 4. An adsorption mechanism is fixedly connected to the side of the pressure-relieving mechanism away from the flange plate 4.

[0025] The adsorption mechanism includes a negative pressure plate shell 5, a negative pressure pipe connector 6, and adsorption heads 7. The negative pressure plate shell 5 is fixedly connected to the pressure relief mechanism. A negative pressure pipe connector 6 is connected to one side of the negative pressure plate shell 5, and a number of evenly arranged adsorption heads 7 are connected to the side of the negative pressure plate shell 5 away from the pressure relief mechanism. A negative pressure device is connected to the negative pressure pipe connector 6. When the negative pressure device is working, a negative pressure is generated in the negative pressure plate shell 5, and the adsorption heads 7 adsorb and fix the edge of the automotive interior trim covering, preventing material detachment during the edge-flipping operation of the automotive interior trim covering and making the edge-flipping operation more stable.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown: The flipping mechanism includes a stepper motor 8, a lead screw 9, a nut block 10, a swing arm 11, and a slot 12. The stepper motor 8 is fixed to one end of the base plate 1 away from the fixed plate 2. The main shaft end of the stepper motor 8 passes through the base plate 1 and is fixedly connected to the lead screw 9. The lead screw 9 is located on the central axis of the base plate 1. The nut block 10 is threaded onto the lead screw 9. The inner wall of the base plate 1 is in frictional contact with the outer wall of the nut block 10. The upper side wall of the nut block 10 is hinged to the swing arm 11. The upper side wall of the base plate 1 has an elongated slot 12, which is parallel to the lead screw 9. The upper end of the swing arm 11 passes through the slot 12 and is hinged to the side wall of the flanging plate 4. When it is necessary to perform flanging operation on the edge of the automotive interior covering, the edge of the automotive interior covering is placed in the adsorption mechanism. The adsorption mechanism adsorbs and fixes the edge of the covering. The stepper motor 8 is started to work, driving the lead screw 9 to rotate. Since the lead screw 9 is threadedly connected to the nut block 10, the nut block 10 is forced to move at this time, which can push the swing arm 11 to swing, thereby driving the flanging plate 4 to swing to a vertical state, realizing the flanging operation on the automotive interior covering, and the operation is stable.

[0027] like Figure 1 and Figure 4As shown: A slide rail 13 is fixedly connected to the left and right side walls of the base plate shell 1, and the two slide rails 13 are arranged opposite each other and are parallel to the lead screw 9. A slider 14 is movably connected to the inner wall of each of the two slide rails 13, and a slide rod 15 is vertically connected to the outer wall of each of the two sliders 14. Both slide rods 15 are parallel to the flange plate 4. A swing rod 16 is hinged to the far end of each of the two slide rods 15. The upper end of each swing rod 16 is hinged to the corresponding end of the flange plate 4. That is, each swing rod 16 is hinged to the same side end of the flange plate 4. When the flipping mechanism drives the flange plate 4 to flip, it can drive the swing rod 16 to swing and move, thereby driving the slider 14 fixed to the slide rod 15 to slide in the slide rail 13. This can play a guiding and supporting role in the flipping of the flange plate 4, making the flipping of the flange plate 4 more stable.

[0028] like Figure 3 As shown: The pressure-relieving mechanism includes movable rods 17, pressure-relieving plates 18, and pressure-relieving springs 19. Two movable rods 17 are symmetrically inserted into the side wall of the flange plate 4, and both are slidably connected to the flange plate 4. The end of each movable rod 17 away from the flange plate 4 is fixedly connected to the pressure-relieving plate 18. The pressure-relieving plate 18 is attached to and fixedly connected to the side wall of the negative pressure plate shell 5. Two pressure-relieving springs 19 are fixedly connected between the flange plate 4 and the pressure-relieving plate 18, and each pressure-relieving spring 19 is sleeved on the outside of one of the movable rods 17. When the adsorption mechanism drives the edge of the automotive interior trim to flip, the edge of the trim is pressed against the automotive interior trim. At this time, the pressure-relieving plate 18 fixed to the negative pressure plate shell 5 can be pushed to move. At this time, the two pressure-relieving springs 19 are compressed and contracted to generate elastic force, which can buffer the pressure exerted by the adsorption mechanism on the edge of the trim and the automotive interior trim, prevent excessive pressure from deforming the automotive interior trim, and improve the processing quality.

[0029] like Figure 3 As shown: the end of the moving rod 17 away from the pressure relief plate 18 extends to the rear of the flange plate 4 and is fixedly connected to the stop block 20 to prevent the moving rod 17 from separating from the flange plate 4.

[0030] like Figure 1 As shown: The adsorption head 7 is made of silicone material. The side wall of the adsorption head 7 has an adsorption hole that is connected to the negative pressure plate shell 5, which can stably adsorb the edge of the car interior covering.

[0031] like Figure 1 As shown: The bottom of the base plate shell 1 is fixedly connected to the mounting bracket 21, which allows the device to be installed on the flanging processing table of automotive interior covering parts.

[0032] The working principle of this embodiment is as follows: When using this device to perform the flanging operation of automotive interior trim, there are four sets of this device. The four sets of flanging mechanisms are arranged around the periphery of the automotive interior trim. The four edges of the automotive interior trim are placed on the four adsorption mechanisms respectively. The negative pressure device is connected to the negative pressure pipe connector 6. When the negative pressure device is working, a negative pressure is generated in the negative pressure plate shell 5. The adsorption head 7 adsorbs and fixes the edges of the automotive interior trim, preventing material detachment during the flanging operation and making the flanging operation more stable. Then, the stepper motor 8 is started to work, driving the lead screw 9 to rotate. Since the lead screw 9 is threadedly connected to the nut block 10, the nut block 10 is forcibly displaced at this time, which can push the swing arm 11 to swing, thereby driving the flanging plate 4 to swing to a vertical state, thus realizing the flanging operation of the automotive interior trim. The operation is stable.

[0033] When the adsorption mechanism causes the edge of the automotive interior trim to flip, the edge of the trim is pressed against the automotive interior trim. At this time, the pressure relief plate 18, which is fixed to the negative pressure plate shell 5, can be pushed to move. At this time, the two pressure relief springs 19 are compressed and contracted to generate elastic force, which can buffer the pressure of the adsorption mechanism on the edge of the trim and the automotive interior trim, prevent excessive pressure from deforming the automotive interior trim, and improve the processing quality.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
