Description

Technical Field

[0001] The invention relates to the technical field of automobile interior processing, and in particular to a processing and polishing device and method for automobile plastic interior decoration parts. Background Art

[0002] Car interior frames usually refer to a decorative material used inside the vehicle. While playing a decorative role, they can also protect the car's structure (such as the dashboard frame, center console panel and display frame, etc.) from damage. Car interior frames are usually made of various types of plastics and are lightweight, cost-effective and easy to shape. Most of the existing interior frames are regular shapes such as round or rectangular.

[0003] At present, the processing techniques such as injection molding and blow molding are mainly used for processing rectangular interior frames. After demolding and taking out the finished product, the interior frame needs to be cleaned, such as trimming and cutting the inner and outer sides of the rectangular interior frame, so as to improve the quality and texture of the finished product. Secondly, in order to improve the aesthetics of the interior frame, the inner and outer sides of the interior frame will be processed and polished to improve the surface finish of the interior frame. At present, when performing the polishing process, the interior frame needs to be fixed first, and then the inner and outer sides of the interior frame are polished and polished in turn by moving the polishing equipment (such as the polishing wheel machine) to improve the surface finish.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0030] like Figure 1 and Figure 2As shown, a processing and polishing device for automobile plastic interior decoration parts comprises: a base 1, the upper end surface of the base 1 is provided with four sliding grooves evenly distributed in the circumferential direction, a driving plate 2 is slidably arranged in the sliding groove, a lifting frame 3 corresponding to the driving plates 2 is fixedly arranged on the upper end surface of the base 1, an L-shaped guide plate 4 is commonly arranged on the left driving plate 2 and the front driving plate 2 as well as on the right driving plate 2 and the rear driving plate 2, the two guide plates 4 are centrally symmetrical about the vertical center line of the base 1, and the two guide plates 4 are staggered up and down, and a clamping unit 5 for clamping the interior decoration frame is commonly arranged between the four driving plates 2.

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, a moving box 6 is commonly arranged between the four driving plates 2, and a grinding mechanism 7 is arranged on the moving box 6. The grinding mechanism 7 includes a center plate 70. The lower end surface of the moving box 6 is rotatably provided with the center plate 70 via a rotating shaft. Both ends of the center plate 70 are fixedly provided with moving plates 700 via multi-stage telescopic rods. The lower end of the moving plate 700 is rotatably provided with a processing roller 701 via a processing shaft with a vertical axis. The processing shaft is connected to an external motor 1, and the rotating shaft is connected to an external motor 2. The grinding mechanism 7 also includes a fixing unit 9 arranged on the moving box 6.

[0032] like Figure 1 , Figure 2 and Figure 6 As shown, the processing shaft is provided with a guide unit 8 for guiding the movement of the processing roller 701, the guide plate 4 is provided with an L-shaped guide groove 80, and the guide unit 8 includes a guide block 800 for guiding the movement of the processing roller 701 after cooperating with the guide groove 80.

[0033] During operation, the interior trim frame to be polished is first placed on the lifting frame 3, and then the clamping unit 5 and the polishing mechanism 7 are adjusted according to the end face to be processed. The polishing of the inner side of the interior trim frame is taken as an example for explanation. The clamping unit 5 clamps the interior trim frame by clamping the outer side of the interior trim frame, and makes the center of the interior trim frame coincide with the center of the base 1. During this process, the two guide plates 4 move to the specified position, and then the moving box 6 moves downward. During the downward movement of the moving box 6, the fixing unit 9 locks the two guide plates 4 to improve the stability of the subsequent processing process. As the moving box 6 continues to move downward, the guide block 800 in the guide unit 8 moves to the corresponding guide groove 80. At the same time, the two processing rollers 701 are guided by the guide unit 8. They are all tightly attached to the diagonal parts of the inner side surface of the interior decoration frame. It should be noted that the circumferential surface of the processing roller 701 is provided with sandpaper (not shown in the figure) for polishing and improving the surface finish by pasting before the processing operation. The external motor 1 drives the processing roller 701 to rotate synchronously through the processing shaft. At the same time, the external motor 2 drives the rotating shaft and the center plate 70 to rotate synchronously. The movable plate 700 drives the corresponding two processing rollers 701 to rotate 180 degrees clockwise synchronously. In this process, the processing roller 701 processes the inner side surface of the interior decoration frame, and the guide block 800 guides the corresponding processing roller 701 to move in the corresponding section to ensure the polishing quality of the processing roller 701. After completing the above operations, the movable box 6 is moved upward and the polishing mechanism 7 and the clamping unit 5 are reset.

[0034] Then, the placement of the interior decoration frame is adjusted, and the above operation is repeated so that the clamping unit 5 can open and clamp the inner side surface of the interior decoration frame, and polish the outer side surface of the interior decoration frame.

[0035] like Figure 1 , Figure 5 and Figure 6 As shown, the guide unit 8 also includes a plug-in column 81, and the upper end surface of the movable plate 700 is fixedly provided with the plug-in column 81, and an L-shaped frame 810 is plugged and installed on the plug-in column 81, and the transverse section and the longitudinal section of the L-shaped frame 810 are slidably penetrated by a movable column 811 with a vertical axis, and the lower end surface of the movable column 811 is fixedly connected to the corresponding guide block 800, and the upper end surface of the movable column 811 is fixedly provided with a mounting block, and a spring 812 mounted on the movable column 811 is fixedly provided between the mounting block and the L-shaped frame 810.

[0036] like Figure 6 As shown, the guide block 800 is an isosceles trapezoid with the small end facing downward, and the two inclined surfaces of the guide block 800 are both facing the inner wall of the guide groove 80 extending along the length direction, and the upper end of the guide groove 80 is chamfered.

[0037] like Figure 1 and Figure 5As shown, the fixed unit 9 includes a rotating plate 901, and the lower end surface of the movable box 6 is rotatably provided with a rotating cylinder 90 sleeved on the rotating shaft, and the rotating cylinder 90 is fixedly provided with a rotating plate 901, and the rotating plate 901 is fixedly provided with two groups of column groups corresponding to the junctions of the two guide plates 4, and the column group includes a plurality of fixed columns 902 which are equidistantly distributed along the length direction of the rotating plate 901 and the axis extends from top to bottom, and the lower end surface of the fixed column 902 is chamfered.

[0038] During operation, the processing of the inner side of the interior frame is used as an example to illustrate that first, the L-shaped frame 810 and the movable column 811 thereon are plugged and installed on the plug-in column 81 (the plug-in method of the L-shaped frame 810 during the processing of the inner side of the interior frame is shown in FIG. Figure 5 and Figure 6 ), after the transverse and longitudinal sections of the two guide plates 4 cooperate with each other to clamp the outer side of the interior decoration frame, the movable box 6 is moved downward manually, and the movable box 6 drives the center plate 70, the processing roller 701 and the rotating plate 901 thereon to move downward synchronously, and the rotating plate 901 drives the two groups of column groups thereon to move downward synchronously. It should be noted that the fixed columns 902 in the two groups of column groups correspond one to one, and each fixed column 902 corresponds to the fixing requirements of interior decoration frames of different sizes. The two guide plates 4 are limited by moving the two fixed columns 902 downward and inserting them into the two guide grooves 80, so as to improve the stability of the processing roller 701 during the movement during subsequent processing and polishing.

[0039] It should be noted that before the guide block 800 moves down and snaps into the corresponding guide groove 80, the length of the multi-stage telescopic rod is adjusted so that the multi-stage telescopic rod drives the movable plate 700, the processing roller 701 and the L-shaped frame 810 thereon to approach the adjacent guide plate 4, so that the subsequent guide block 800 moves down and snaps into the guide groove 80. As the movable box 6 continues to move down, the center plate 70 drives the movable plate 700 and the processing roller 701 to move down synchronously, so that the two processing rollers 701 move down to the two diagonal positions of the interior trim frame. At the same time, in this process, the movable plate 700 drives the L-shaped frame 810 and the movable column 811 thereon to move down synchronously, so that the L-shaped frame 810 drives the guide block 800 thereon to snap into the corresponding guide groove 80 (see Figure 6 ), the chamfer of the guide groove 80 and the inclined surface of the guide block 800 are matched to facilitate the guide block 800 to be inserted into the corresponding guide groove 80, and then the external motor 1 and the external motor 2 work synchronously, and the center plate 70 drives the two processing rollers 701 to rotate 180 degrees while the processing rollers 701 rotate on their own.

[0040] Take the left processing roller 701 as an example for explanation. During the movement of the processing roller 701, the processing roller 701 drives the L-shaped frame 810 thereon to move synchronously. The guide block 800 on the left side of the L-shaped frame 810 guides the processing roller 701 to move forward. When the processing roller 701 moves forward to the angle in front of the left side of the interior trim frame, the inclined surface of the guide block 800 on the front side of the L-shaped frame 810 contacts the lateral section of the corresponding guide plate 4, and the guide block 800 moves upward, and the spring 812 The guide block 800 is compressed, and as the processing roller 701 continues to move forward, the guide block 800 is gradually stuck into the lateral section of the corresponding guide groove 80 under the action of the elastic force generated by the compression of the spring 1 812. Then, as the center plate 70 rotates, the processing roller 701 moves to the right, and the inclined surface of the guide block 800 on the left side of the L-shaped frame 810 contacts the inner wall of the guide groove 80, and gradually moves upward, and finally moves out of the guide groove 80. Then, the guide block 800 on the front side guides the processing roller 701 to move to the right for processing and grinding.

[0041] In summary, by sequentially inserting the two guide blocks 800 on the same L-shaped frame 810 into the corresponding guide grooves 80 , the moving processing and grinding process of the processing roller 701 is sequentially guided, thereby improving the stability during the processing.

[0042] When the outer side of the interior trim frame needs to be processed and polished, the positions of the two guide blocks 800 are adjusted during the process of plugging and installing the L-shaped frame 810 to facilitate adapting to the guiding needs in different situations.

[0043] like Figure 1 and Figure 2 As shown, a cavity is provided inside the moving box 6, and a mounting shaft 60 with a vertical axis is fixedly provided in the inner cavity of the moving box 6. Two gears 600 distributed up and down are rotatably sleeved on the mounting shaft 60. Two groups of toothed plate groups corresponding to the gears 600 are slidably provided on the moving box 6. The toothed plate groups include two rack plates 601 which are symmetrical about the center of the mounting shaft 60 and meshed with the corresponding gears 600. A mounting frame 602 is fixedly provided on the driving plate 2, and the rack plate 601 is slidably provided on the corresponding mounting frame 602.

[0044] like Figure 1 , Figure 2 and Figure 3As shown, the clamping unit 5 includes a moving frame 50, and the upper end surface of the driving plate 2 is slidably provided with an L-shaped moving frame 50, the horizontal section of the moving frame 50 is close to the junction of two adjacent guide plates 4, and the left and right moving frames 50 are slidably arranged on the corresponding driving plate 2, and the front and rear moving frames 50 are slidably arranged on the corresponding driving plate 2, and the vertical sections of the front and rear moving frames 50 are slidably arranged on the corresponding driving plate 2, and the front and rear moving frames 50 are slidably arranged on the corresponding driving plate 2. The vertical sections of the front and rear moving frames 50 slide forward and backward and are penetrated by a connecting rod 51, and the connecting rod 51 is fixedly connected to the corresponding guide plate 4, and a spring 52 mounted on the corresponding connecting rod 51 is fixedly arranged between the guide plate 4 and the corresponding moving frame 50, and the vertical sections of the left and right moving frames 50 are fixedly connected to the corresponding guide plate 4 through a connecting block, and a driving group 53 is arranged on the base 1.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, the driving group 53 includes a rectangular block 530, and a rectangular block 530 opposite to the driving plate 2 is fixedly provided on the lower end surface of the base 1, and a threaded rod 531 penetrating the corresponding driving plate 2 is rotatably provided on the rectangular block 530, and the threaded rod 531 is threadedly matched with the corresponding driving plate 2, and a first bevel gear 532 is fixedly provided on the opposite surfaces of the four threaded rods 531, and a transmission shaft 533 with a vertical axis and located between the four rectangular blocks 530 is rotatably provided on the lower end surface of the base 1, and a second bevel gear 534 meshing with the first bevel gear 532 is fixedly sleeved on the transmission shaft 533, and the transmission shaft 533 is connected to the external motor three.

[0046] like Figure 1 , Figure 2 and Figure 4 As shown, the clamping unit 5 also includes a mounting square cylinder 54, and the lower end surfaces of the transverse section and the longitudinal section of the front guide plate 4 are fixedly provided with the mounting square cylinder 54 through a connecting frame, and the lower end surfaces of the transverse section and the longitudinal section of the rear guide plate 4 are also fixedly provided with the mounting square cylinder 54, and the length directions of the mounting square cylinders 54 on the two guide plates 4 are perpendicular to each other, and L-shaped clamping plates 540 are arranged on both sides of the length direction of the mounting square cylinder 54, and the two clamping plates 540 on the same mounting square cylinder 54 are symmetrical to each other and the horizontal sections of the two clamping plates 540 are back to back, and an adjustment group is arranged on the mounting square cylinder 54.

[0047] During operation, the process of grinding the inner side of the interior decoration frame is taken as an example to illustrate. In this process, the interior decoration frame is placed on the lifting frame 3 by clamping the clamping plate 540 on the guide plate 4 close to the central area of ​​the base 1. Then, the external motor 3 drives the transmission shaft 533 and the No. 2 bevel gear 534 thereon to rotate synchronously. The engagement between the No. 2 bevel gear 534 and the No. 1 bevel gear 532 enables all No. 1 bevel gears 532 to drive the corresponding threaded rods 531 to rotate synchronously. The threaded cooperation between the threaded rods 531 and the corresponding drive plates 2 enables all drive plates 2 to move synchronously, and the drive plates 2 are all close to the moving box 6.

[0048] As the front and rear driving plates 2 move, the two driving plates 2 drive the corresponding guide plates 4 to move in the front and rear directions through the corresponding moving frames 50, and make the vertical sections of the corresponding clamping plates 540 on the lateral sections of the two guide plates 4 contact the front and rear sides of the interior decoration frame respectively. As the two driving plates 2 continue to move, the spring 2 52 is compressed. The elastic force generated by the compression of the spring 2 52 makes the vertical sections of the clamping plates 540 on the lateral sections of the two guide plates 4 cooperate with each other to clamp the interior decoration frame in the front and rear directions. As the driving plate 2 continues to move, the left The driving plates 2 on the right side drive the corresponding guide plates 4 to move synchronously through the corresponding moving frames 50, and the two guide plates 4 move in the left and right directions. Therefore, the vertical sections of the clamping plates 540 on the longitudinal sections of the two guide plates 4 cooperate with each other to clamp the interior decoration frame in the left and right directions. The circumferential clamping operation of the interior decoration frame is completed in the above manner. During the clamping process of the clamping plates 540, the lateral sections of the clamping plates 540 cooperate with the lifting frames 3 to limit the up and down directions of the interior decoration frame. The limiting and fixing of the interior decoration frame is completed in the above manner, thereby improving the stability during subsequent processing and polishing.

[0049] It should be noted that, in the initial state, the movable box 6 is located directly above the center of the base 1. During the above-mentioned clamping process, when the two left and right driving plates 2 opposite to each other approach each other and the two front and rear driving plates 2 opposite to each other approach each other, the rack plate 601 on the driving plate 2 is meshed with the corresponding gear 1 600, so that the movable box 6 is always located directly above the center of the base 1, which facilitates the subsequent processing roller 701 to be close to the inner side of the interior trim frame and guide the processing and polishing process and the fixing and locking process of the fixing unit 9, thereby improving the accuracy of the subsequent processing and polishing process.

[0050] like Figure 4As shown, the adjustment group includes a gear 2 55, and a gear 2 55 is rotatably arranged in the mounting square cylinder 54 through the gear shaft. Two tooth plates 550 symmetrical about the center of the gear shaft are slidably arranged in the mounting square cylinder 54, and the tooth plates 550 slide along the length direction of the corresponding mounting square cylinder 54. The tooth plates 550 are fixedly connected to the corresponding clamping plates 540 on the mounting square cylinder 54. A plurality of adjustment grooves 551 are penetrated on the gear 2 55, and a clamping column 552 that cooperates with the adjustment grooves 551 is inserted through the upper end surface of the mounting square cylinder 54.

[0051] Before processing and polishing, the position of the clamping plate 540 is adjusted according to the size of the processed and polished interior trim frame.
