[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 10 , the present invention provides a technical solution: A trimming device for automobile parts processing and forming, comprising a tooling table 1, wherein two parallel through grooves 101 are horizontally opened from the upper end surface to the lower end surface of the tooling table 1, and then a convex structure slide bar 102 is fixedly installed on the lower end surface of the tooling table 1 and parallel to the through grooves 101. Figure 2 shown.

[0025] Then, symmetrical moving rods 106 are slidably installed on the outer sides of the front and rear sliding rods 102. The moving rod 106 has a U-shaped structure, and both ends are located inside the through groove 101. A through sliding groove 107 is opened on the left and right sides of the front and rear edge positions of the moving rod 106. The structure of the sliding groove 107 matches that of the sliding rod 102, and the sliding rod 102 and the sliding groove 107 are slidably combined, as shown in FIG. Figure 3 shown.

[0026] Then, an arc-shaped plate 108 is fixedly installed on the top of the moving rod 106. Furthermore, a main motor 103 is fixedly installed at the center position of the lower end surface of the workbench 1. An adjusting rod 104 is fixedly installed on the output shaft of the main motor 103. Connecting rods 105 are rotatably installed at the lower ends of the adjusting rod 104. The ends of the two connecting rods 105 away from the adjusting rod 104 are rotatably installed at the middle part of the lower end of the moving rod 106. Figure 2 shown.

[0027] During use, the main motor 103 is started, and the output shaft of the main motor 103 drives the adjusting rod 104 to rotate, and the adjusting rod 104 drives the connecting rod 105 to rotate. When the connecting rod 105 rotates, it drives the moving rod 106 to slide along the path of the sliding rod 102 through the sliding groove 107, so that the moving rod 106 and the arc plate 108 can be combined into a ring structure.

[0028] A cavity column 109 is fixedly installed on the inner circumferential surface of the left and right arc-shaped plates 108, a spring 110 is fixedly installed inside the cavity column 109, an arc-shaped clamping plate 111 is fixedly installed on one end of the outer side of the spring 110, and one end of the outer side of the arc-shaped clamping plate 111 is slidably installed inside the cavity column 109.

[0029] Under the action of the spring 110 , the arc-shaped clamping plate 111 can clamp the lower end of the inner automobile component to ensure that there is no tilting during the trimming process.

[0030] The top of the arc-shaped plate 108 is fixed with a sealing plate 2. The left and right sealing plates 2 can be combined into a sealed rectangular parallelepiped structure to ensure that there will be no interference during the trimming process. Figure 1 shown.

[0031] Then, an L-shaped connecting pipe 201 is fixedly installed on the front and rear side surfaces of the sealing plate 2, a cavity box 204 is fixedly installed on the upper end of the connecting pipe 201, and a fan 205 is fixedly installed on the upper end of the cavity box 204. Then, three water tanks 202 are fixedly installed on the outer circumferential surface of the connecting pipe 201, a water pump is fixedly installed on the inner lower end surface of the water tank 202, and a water supply pipe 203 is fixedly installed on the upper end of the water pump, and the top of the water supply pipe 203 passes through the water tank 202 and is fixedly connected to the upper end surface of the cavity box 204, and is in a through state.

[0032] During use, after the fan 205 is started, air can be sucked into the cavity box 204 through the connecting pipe 201. At this time, the water pump is started to transport the water source inside the water tank 202 to the inside of the cavity box 204. When transported to the inside of the cavity box 204, the water source becomes mist, which reduces the dust and is then discharged through the fan 205.

[0033] A vertical groove 206 is provided on the inner side walls of the left and right sealing plates 2, and a driving motor 301 of the trimming assembly 3 is fixedly installed on the top of the sealing plate 2. A reciprocating screw 302 is fixedly installed on the output shaft of the driving motor 301. The reciprocating screw 302 is located inside the groove 206, and a moving frame 303 is screwed and installed on the circumferential surface of the reciprocating screw 302. The moving frame 303 is slidably installed inside the groove 206. Figure 6 shown.

[0034] Furthermore, a first motor 304 is fixedly installed at the outer upper edge of the movable frame 303, and a first groove wheel 305 is fixedly installed on the output shaft of the first motor 304. Then, a second groove wheel 306 is rotatably installed at the outer upper end of the movable frame 303. Tracks are rotatably installed on the circumferential surfaces of the first groove wheel 305 and the second groove wheel 306. Then, a screw rod 307 is rotatably installed from the upper end of the second groove wheel 306 to the inside of the movable frame 303. The screw rod 307 is threadedly connected to the second groove wheel 306, and a ring 308 is fixedly installed at the lower end of the screw rod 307.

[0035] During use, the first motor 304 is started, and the first motor 304 drives the track through the first groove wheel 305, and the track drives the second groove wheel 306, and the second groove wheel 306 drives the screw rod 307 to rotate. When the screw rod 307 rotates, it can move the ring 308 up and down.

[0036] A second motor 317 is fixedly mounted on the outer edge of the lower end of the movable frame 303. A convex shaft 318 is fixedly mounted on the output shaft of the second motor 317 and inside the movable frame 303. A connecting slip ring 310 is slidably mounted on the outer circumferential surface of the convex shaft 318. Figure 7 shown.

[0037] It should be noted that there are two outward protrusions on the circumferential surface of the convex shaft 318, and two U-shaped matching grooves are opened on the inner circumferential surface from the upper end to the lower end of the connecting slip ring 310, which are used to allow the connecting slip ring 310 to slide and connect with the convex shaft 318.

[0038] A trapezoidal plate 309 is fixedly mounted on the lower end of the connecting slip ring 310 . The internal structure of the trapezoidal plate 309 matches the convex shaft 318 . The outer circumferential surface of the connecting slip ring 310 is a concave structure, and the ring 308 is located inside the concave structure.

[0039] Therefore, when the circular ring 308 moves up and down, it will bring the connecting slip ring 310 up and down synchronously, and then bring the trapezoidal plate 309 up and down.

[0040] Then, two symmetrical rotating rods 311 are rotatably installed at the lower end of the outer side of the mobile frame 303, an adjusting wheel 312 is rotatably installed at the upper left end of the rotating rod 311, and a trimming motor 313 is fixedly installed inside the other end. The output shafts at both ends of the trimming motor 313 are fixedly installed with third groove wheels 314. Then, fourth groove wheels 315 are rotatably installed on the upper and lower sides of one end of the outer side of the rotating rod 311, and a grinding belt 316 is rotatably installed on the circumferential surfaces of the fourth groove wheel 315 and the third groove wheel 314. Figure 10 shown.

[0041] It should be noted that the position where the rotating rod 311 and the movable frame 303 are rotatably connected is in a strong connection, and the rotating rod 311 will generate a self-resetting force so that the two ends on the left side are always in a state of being close to each other, but due to the interference of the trapezoidal plate 309, the rotating rod 311 can be in a parallel or tilted state.

[0042] The trimming motor 313 is started, and the output shaft of the trimming motor 313 drives the third groove wheel 314 to rotate, and the third groove wheel 314 drives the grinding belt 316 to rotate, and the grinding belt 316 drives the fourth groove wheel 315 to rotate synchronously.

[0043] By making the upper and lower sizes of the trapezoidal plate 309 inconsistent, the left side of the rotating rod 311 can be changed to be in a state of approaching or moving away, and the distance between the two side grinding belts 316 on the right side is also in a state of approaching-moving away, thereby realizing the grinding operation of different protruding parts.

[0044] Working principle: During operation, in the process of use, the main motor 103 is started, and the output shaft of the main motor 103 drives the adjusting rod 104 to rotate, and the adjusting rod 104 drives the connecting rod 105 to rotate. When the connecting rod 105 rotates, it drives the moving rod 106 to slide along the path of the sliding rod 102 through the sliding groove 107, so that the moving rod 106 and the arc plate 108 can be combined into a ring structure.

[0045] A cavity column 109 is fixedly installed on the inner circumferential surface of the left and right arc-shaped plates 108, a spring 110 is fixedly installed inside the cavity column 109, an arc-shaped clamping plate 111 is fixedly installed on one end of the outer side of the spring 110, and one end of the outer side of the arc-shaped clamping plate 111 is slidably installed inside the cavity column 109.

[0046] Under the action of the spring 110 , the arc-shaped clamping plate 111 can clamp the lower end of the inner automobile component to ensure that there is no tilting during the trimming process.

[0047] A sealing plate 2 is fixedly installed on the top of the arc-shaped plate 108 , and the two sealing plates 2 on the left and right can be combined into a sealed rectangular parallelepiped structure.

[0048] During the grinding operation, after the fan 205 is started, air can be sucked into the cavity box 204 through the connecting pipe 201. At this time, the water pump is started, and the water pump transports the water source inside the water tank 202 to the inside of the cavity box 204. When transported to the inside of the cavity box 204, the water source is in the form of mist, which reduces the dust and is then discharged through the fan 205.

[0049] Furthermore, the first motor 304 is started, and the first motor 304 drives the crawler belt through the first groove wheel 305, and the crawler belt drives the second groove wheel 306, and the second groove wheel 306 drives the screw rod 307 to rotate. When the screw rod 307 rotates, it can move the ring 308 up and down.

[0050] The circular ring 308 slides up and down, causing the connecting slip ring 310 to slide up and down, and then causing the trapezoidal plate 309 to slide up and down.

[0051] The trimming motor 313 is started, and the output shaft of the trimming motor 313 drives the third groove wheel 314 to rotate, and the third groove wheel 314 drives the grinding belt 316 to rotate, and the grinding belt 316 drives the fourth groove wheel 315 to rotate synchronously.

[0052] It should be noted that, when the second motor 317 is started, the output shaft of the second motor 317 rotates with the cam 318. Since there are two outward protrusions on the circumferential surface of the cam 318, and there are two inward depressions on the inner circumferential surface of the connecting slip ring 310, the protruding position of the cam 318 matches the depressed position of the connecting slip ring 310, and the cam 318 can rotate synchronously with the connecting slip ring 310. In the process of rotation, since the outer circumferential surface of the connecting slip ring 310 is a depressed structure, and the ring 308 extends to the inside of the depressed structure, the problem of the connecting slip ring 310 automatically falling is prevented, so that when the connecting slip ring 310 rotates, it will rotate synchronously with the trapezoidal plate 309.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
