[0037] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0038] like Figure 1-5 As shown, the present invention provides a grinding device for automobile interior plastic parts, which includes: a processing platform 1, a support platform 2, a clamping mechanism and a grinding mechanism 9;

[0039] The upper end of the processing platform 1 is horizontally fixed with a support table 2 for supporting the plastic part. A clamping mechanism capable of fixing the plastic part is provided on the upper side of the support table 2. The polishing mechanism 9 is movably provided on the processing platform 1 through a moving mechanism 7. The moving mechanism 7 includes a pulley 701 and a belt 702.

[0040] At least two pulleys 701 are spaced apart and vertically rotatably arranged above the processing platform 1 on both sides of the support platform 2, and the distance between the two pulleys 701 is greater than the length of the support platform 2. All the pulleys 701 are connected together by a belt 702. A grinding mechanism 9 is fixedly arranged on the belt 702 facing away from the pulleys 701, so that the grinding mechanism 9 can move along the edge of the plastic part in turn and grind its edge.

[0041] In the above solution, the width of the support platform 2 is greater than the length of the plastic part to be processed.

[0042] During use, the plastic part to be polished is fixed horizontally on the support table 2. Since the width of the support table 2 is greater than the length of the plastic part to be processed, the edge of the plastic part placed on the support table 2 is exposed outside the edge of the support table 2, so that the polishing mechanism 9 can polish its edge later.

[0043] During the grinding process, the pulley 701 is driven to rotate so that the belt 702 mounted on all the pulleys 701 runs horizontally at the upper end of the processing platform 1 and counterclockwise or anticlockwise around the periphery of the support table 2. The belt 702 can drive the grinding mechanism 9 to move along the edge of the plastic part during its horizontal movement, and can grind multiple edges of the plastic part in sequence during its movement.

[0044] Therefore, during the entire grinding process, the four edges of the plastic part can be grinded in sequence without moving or turning the plastic part, thereby improving the grinding efficiency.

[0045] In a preferred embodiment of the present invention, the grinding mechanism 9 includes: a grinding seat 901, a motor box 903 and a grinding disc 904; wherein,

[0046] The upper end of the support platform 2 is located above the belt 702, and a grinding seat 901 is fixedly provided on the belt 702 facing away from the pulley 701. The grinding seat 901 located above the belt 702 is horizontally and movably provided with a motor box 903 that can be approached toward the plastic part. A grinding motor is horizontally fixed inside the motor box 903, and the output end of the grinding motor extends from the motor box 903 and is coaxially fixed with a grinding disc 904 through a coupling.

[0047] In the above embodiment, during use, the motor box 903 is driven horizontally toward the plastic part until the grinding disc 904 on the motor box 903 contacts the edge of the plastic part. Then, the grinding motor in the motor box 903 is activated to rotate the grinding disc 904 to grind the edge of the plastic part. Simultaneously, the moving mechanism 7 is activated to drive the grinding mechanism 9 so that the belt 701 of the moving mechanism 7 drives the grinding seat 901 to move along the edge of the plastic part and grind the edge of the plastic part.

[0048] In a preferred embodiment of the present invention, the grinding mechanism 9 further includes: a second electric telescopic rod 902; wherein,

[0049] A second electric telescopic rod 902 is fixedly provided horizontally on the upper end of the grinding seat 901 , and a motor box 903 is fixedly provided on the telescopic end of the second electric telescopic rod 902 .

[0050] In the above solution, the motor box 903 and the grinding disc 904 fixed on the motor box 903 are driven to move by the second electric telescopic rod 902 so that the grinding disc 904 approaches the plastic part on the support platform 2.

[0051] In a preferred embodiment of the present invention, the clamping mechanism includes: a pressing plate 3, a vacuum generator 5 and a vacuum suction cup 6; wherein,

[0052] A bracket 8 with a height greater than that of the grinding mechanism 9 is vertically fixed above the processing platform 1. A pressing plate 3 with a hollow structure inside and capable of resting on the supporting platform 2 is horizontally and liftably arranged inside the bracket 8 located above the supporting platform 2. A plurality of vacuum suction cups 6 that are connected to the interior of the pressing plate 3 and can be adsorbed on plastic parts are evenly and vertically fixed at the bottom end of the pressing plate 3. A vacuum generator 5 is also fixed on the top of the bracket 8, and the vacuum generator 5 is connected to the interior of the pressing plate 3 through an air pipe.

[0053] In the above scheme, when in use, the pressing plate 3 is driven to descend in the vertical direction so that several of the vacuum suction cups 6 at the lower end of the pressing plate 3 are pressed against the plastic part on the support table 2, and the vacuum generator 5 is started so that all the vacuum suction cups 6 at the lower end of the pressing plate 3 are adsorbed on the plastic part, so as to firmly fix the plastic part on the support table 2, thereby preventing the plastic part from shifting and affecting the grinding efficiency during the grinding process of the edge of the plastic part by the grinding mechanism 9.

[0054] The vacuum generator 5 is a conventionally known technology and is used in conjunction with the vacuum cup 6. Its specific structure will not be described here. Its operating principle is as follows: By activating the vacuum generator 5, the vacuum cup 6 is sucked from the vacuum cup 6 to generate a negative pressure, thereby firmly adhering to the plastic part. After processing is completed, the positive air generator 5 steadily inflates the vacuum cup 6, causing the negative pressure inside the vacuum cup 6 to decrease to zero pressure or a slightly positive pressure, thereby releasing the vacuum cup 6 from the plastic part.

[0055] In a preferred embodiment of the present invention, the clamping mechanism further comprises: a first electric telescopic rod 4 for driving the pressing plate 3 to move up and down in the vertical direction; wherein,

[0056] A first electric telescopic rod 4 is vertically and fixedly provided on the top of the bracket 8 , and the telescopic end of the first electric telescopic rod 4 is fixed on the pressing plate 3 .

[0057] In the above solution, the pressing plate 3 is driven to move up and down in the vertical direction by the first electric telescopic rod 4 .

[0058] In a preferred embodiment of the present invention, the second electric telescopic rod 902 is a servo electric cylinder.

[0059] In the above solution, the servo electric cylinder is a modular product that integrates a servo motor and a lead screw. It converts the rotational motion of the servo motor into linear motion. At the same time, it converts the best advantages of the servo motor: precise speed control, precise rotational speed control, and precise torque control into precise speed control, precise position control, and precise thrust control. It realizes a new product series of high-precision linear motion and is compact in size, taking up little space during assembly.

[0060] In addition, the No. 1 electric telescopic rod 4 can also be a servo electric cylinder, and the specifications and sizes of the No. 1 electric telescopic rod 4 and the No. 2 electric telescopic rod 902 can be appropriately selected to the corresponding specifications and sizes according to the actual assembly environment.

[0061] In a preferred embodiment of the present invention, a plurality of travel wheels 13 capable of rolling on the processing platform 1 are rotatably provided at intervals on both sides of the grinding seat 901 .

[0062] In the above solution, the traveling wheel 13 can forcefully support the grinding seat 901 that moves along with the belt 702 , so that the grinding seat 901 can move smoothly and reliably along with the belt 702 on the processing platform 1 .

[0063] In a preferred embodiment of the present invention, a support leg 11 is vertically fixed at the bottom end of the grinding seat 901, and a ball 12 is rollably provided at the bottom end of the support leg 11. The upper part of the processing platform 1 is recessed inward to form a guide groove 10 adapted to the belt 702, and the bottom end of the ball 12 extends into the guide groove 10 and is rollingly connected thereto.

[0064] In the above scheme, the support leg 11 plays the role of supporting the cutting seat 901. In addition, through the cooperation of the ball 12 of the support leg 11 and the guide groove 10 adapted thereto, the grinding seat 901 can be smoothly and reliably operated and moved along the specified route.

[0065] In a preferred embodiment of the present invention, the moving mechanism 7 further includes: a moving motor 703; wherein,

[0066] The interior of the processing platform 1 is a hollow structure, and the central shaft portion of any one of the pulleys 701 extends into the interior of the processing platform and is coaxially fixedly connected to the mobile motor 703 vertically fixed inside the processing platform 1 through a coupling.

[0067] In the above solution, the moving motor 703 drives all the pulleys 701 to rotate and drives the belt 702 to run in the horizontal direction.

[0068] In summary, the automobile interior plastic parts grinding device provided by the utility model overcomes the problem in the prior art that workers need to adjust or flip the plastic parts so that each edge of the plastic parts faces the grinding wheel for grinding. The operation is cumbersome, increases the workload of workers, reduces work efficiency, and there are certain safety hazards for workers during operation.
