Description

Technical Field

[0001] The invention relates to the technical field of automobile interior processing, and in particular to a method for preparing a polymer flame-retardant automobile interior decoration part. Background Art

[0002] Due to reasons such as line aging, oil line failure and mechanical failure, the car may cause spontaneous combustion, causing great damage to passengers and property. The polymer flame retardant car interior can slow down the speed of car spontaneous combustion, providing passengers with more escape time, thereby reducing casualties of passengers. When processing curved car interior parts, in order to reduce the heat generated by the friction of the drill bit due to continuous work and thus extend the service life of the drill bit, the drill bit needs to be sprayed with coolant to cool it down. When the drill bit is processed vertically, the coolant will accumulate in the curved groove of the interior part due to the horizontally placed interior parts to be processed. At this time, the coolant needs to be dumped. Since there are many interior parts to be processed, manual dumping is often used to clean the coolant residue inside the interior parts, which makes the staff easily tired and thus reduces work efficiency.

A first fixed plate 113 is fixed to one side of the support platform 110, and a third guide rail 160 and one end of a fourth guide rail 170 are fixed to the top of one side of the first fixed plate 113. A plurality of first limit blocks 111 for limiting the first slider 121 and the second slider 122 are fixed on the support platform 110, and first guide grooves 152 are provided on both sides of the fixed arm 150 and one side of the fourth guide rail 170. A plurality of support blocks 112 for fixing the rotating arm 230 are fixed on the support platform 110, and a pushing assembly for feeding is provided on the support platform 110;

[0050] In this embodiment, the pushing assembly includes a second servo motor 180 fixed on the support platform 110, and one end of the motor shaft of the second servo motor 180 is fixed with a first screw rod 181 with one end rotatably connected to one side of the first fixed plate 113, and a push plate 182 is spirally connected to the first screw rod 181, and one end of the push plate 182 is slidably engaged in the first guide rail 114 fixed on the support platform 110. By controlling the second servo motor 180, the push plate 182 pushes multiple clamping units 240 located close to the fourth guide rail 170 close to the feeding table 310, so that the multiple clamping units 240 can be processed in sequence, thereby improving the processing efficiency.

[0051] The clamping mechanism 200 includes a C-shaped clamping block 210, one end of which is rotatably connected to a rotating arm 230. A first gear 220 is fixedly sleeved on the rotating arm 230. A clamping unit 240 for securing an automotive interior workpiece is fixed to one end of the rotating arm 230. The clamping unit 240 includes clamping jaws 241 that are slidably engaged with the two ends of the clamping unit 240. A first spring 242 and a telescopic rod 243 are fixed between one end of the two clamping jaws 241, and the telescopic rod 243 is located inside the first spring 242. By placing the workpiece between the two clamping jaws 241, the workpiece is secured, thereby improving the stability of the workpiece during processing.

[0052] The feeding mechanism 300 includes a feeding table 310 fixed on the other end of the supporting platform 110, another third guide rail 160 is fixed on one side of the feeding table 310, and the other end of the fourth guide rail 170 is fixed on one side of the feeding table 310, and a processing feeding unit is provided on the feeding table 310, and the processing feeding unit includes a second guide groove 350 for sliding the rotating arm 230 opened on the feeding table 310, and the second guide groove 350 is slidably engaged with the first gear 220, and a third servo motor 320 is fixed to one side of the top of the feeding table 310, and a second screw rod 321 is fixed to one end of the motor shaft of the third servo motor 320, and one end of the second screw rod 321 is rotatably connected to the other side of the top of the feeding table 310, and the second screw rod 321 is spirally connected to the inside of the first fixed block 330 that is slidably engaged with the feeding table 310, and the first An electric push rod 340 is fixed to one side of the fixed block 330, and a U-shaped claw 341 is fixed to one end of the electric push rod 340 for sliding engagement with the rotating arm 230. The electric push rod 340 is displaced in the horizontal direction by controlling the third servo motor 320, and the electric push rod 340 is controlled so that the U-shaped claw 341 can push the rotating arm 230 located in the second guide groove 350 to displace within the second guide groove 350. When the rotating arm 230 is displaced to the middle of the second guide groove 350, the clamping unit 240 approaches the processing mechanism 400, and the processing mechanism 400 is controlled to process the workpiece on the clamping unit 240. A first guide groove 152 is formed on one side of each of the multiple third guide rails 160, and a first rack 161 is fixed to one side of each of the multiple fixed arms 150 and the first guide groove 152 of one of the third guide rails 160.

[0053] The supporting platform 110 is provided with a processing mechanism 400 for processing automobile interior parts. The multiple workpieces to be processed are placed in the corresponding clamping units 240. At this time, the first servo motor 140 is controlled to rotate the first rotating shaft 130, so that the C-shaped clamping block 210 drives the clamping unit 240 to rotate. Then, the hydraulic push rod 120 is controlled to move the multiple clamping units 240 to the second guide rail 151. At this time, the multiple first gears 220 are engaged with the corresponding first guide grooves 152, and the clamping units 240 are flipped due to the action of the first gears 220. When the hydraulic push rod After 120 displaces the multiple rotating arms 230 close to the fourth guide rail 170, it controls the pushing assembly to make the multiple clamping units 240 approach and displace them close to the feeding table 310, and the processing feeding unit set on the feeding table 310 displaces the single clamping unit 240 close to the processing mechanism 400 for processing, so that the curved surface of the automobile interior processing part can be relatively vertical to the horizontal plane, so that the coolant used by the processing mechanism 400 during processing can flow out along the curved surface of the processing part, thereby reducing the process of pouring the coolant in the processing part, thereby improving the processing efficiency.

[0054] Specifically, a baffle 360 ​​for assisting in fixing the workpiece is fixed at one end of the feeding table 310. When the workpiece in the clamping unit 240 is being processed, one side of the baffle 360 ​​contacts one side of the workpiece, thereby making the processing more stable. Two second fixed plates 115 are fixed on the support platform 110. The processing mechanism 400 includes a fourth servo motor 410 fixed to one side of the second fixed plate 115. The motor shaft of the fourth servo motor 410 passes through one end of the second fixed plate 115 and is fixed with a third screw rod 411. One end of the third screw rod 411 is rotatably connected to the other side of the second fixed plate 115. The third screw rod 411 is spirally connected to the bottom end of the processing component 430, and the bottom end of the processing component 430 is slidably sleeved with a guide rod 42 fixed between the two second fixed plates 115. 0, a drill unit 431 is fixed to the top of the processing component 430, and a second fixed block 440 is fixed to the top and bottom of the drill unit 431, and a slide groove 442 is opened on both sides of the second fixed block 440, and a second spring 441 is fixed to one end of the second fixed block 440, and a top support arm 450 is fixed to one end of the second spring 441, and a third slider 451 is fixed to both ends of the top support arm 450, and the third slider 451 is slidably engaged in the slide groove 442 on the same side of the second fixed block 440. By controlling the fourth servo motor 410, the processing component 430 can be horizontally displaced on the support platform 110, so that the drill unit 431 is close to the clamping unit 240, and due to the action of the top support arm 450, one side of the workpiece is stably fitted to the baffle 360, thereby improving the stability of the workpiece during processing.

[0055] Specifically, a second rack 351 engaged with the first gear 220 is fixed at one end of the second guide groove 350. By controlling the third servo motor 320 and the electric push rod 340, the rotating arm 230 slides in the second guide groove 350. When the rotating arm 230 slides close to the second rack 351, the first gear 220 and the second rack 351 are engaged. At this time, the first gear 220 causes the clamping unit 240 to rotate, thereby rotating the workpiece to the side of the remote processing assembly 430, which is convenient for the staff to unload, thereby improving work efficiency. A drainage plate 370 for assisting in collecting coolant is fixed at one end of the feeding table 310. The drainage plate 370 can assist in the discharge of coolant flowing out of the workpiece, thereby avoiding splashing of coolant.

[0056] Working principle: When in use, the interior decoration piece to be processed is placed between the two clamping jaws 241. The first spring 242 is used to fix the interior decoration piece to be processed between the two clamping jaws 241. At this time, the C-shaped clamping block 210 at one end of the clamping unit 240 with the interior decoration piece to be processed is clamped to the first rotating shaft 130, so that the two ends of the C-shaped clamping block 210 are in contact with the corresponding second limit block 131 and the multiple rotating arms 230 are clamped in the corresponding first fixed plate 113. At this time, the first servo motor 140 is started, so that the third gear 141 drives the first servo motor 140 to rotate. The second gear 132 is driven to rotate the first rotating shaft 130. Under the action of the second limit block 131, the C-shaped clamping block 210 rotates to a vertical position as the first rotating shaft 130 rotates, thereby verticalizing the multiple clamping units 240. The hydraulic push rod 120 is then activated to move the first slider 121 and the second slider 122 toward the fourth guide rail 170. At this time, the rotating arm 230 enters between two adjacent second guide rails 151 or between the second guide rail 151 and the third guide rail 160, and the first gear 220 slides and engages with the first guide groove 152.

[0057] When the first gear 220 slides to engage with the first rack 161, the first gear 220 rotates due to the pushing action of the hydraulic push rod 120, so that the rotating arm 230 drives the clamping unit 240 to rotate the side of the interior trim to be processed to a suitable position;

[0058] When the hydraulic push rod 120 pushes the first rotating shaft 130 to the side of the rotating arm 230 and contacts the fourth guide rail 170, the second servo motor 180 is started, causing the first screw rod 181 to rotate. Due to the clamping effect of the first guide rail 114, the push plate 182 moves along the first screw rod 181 toward the feeding table 310, so that the push plate 182 pushes the multiple clamping units 240 to fit tightly and causes the rotating arm 230 located near the feeding table 310 to contact one end of the second guide groove 350. At this time, The first and second guide rails 350 are moved to the left and right sides of the work platform 310, and the second and third guide rails 350 are moved to the right and left sides of the work platform 310, respectively. The support arm 430 approaches the clamping unit 240 until one end of the support arm 450 is close to the side of the interior part to be processed inside the clamping unit 240 at one end of the rotating arm 230, and pushes the clamping unit 240 so that the other side of the interior part contacts the baffle 360. At this time, the fourth servo motor 410 is controlled to make the drill unit 431 process the interior part, and the coolant sprayed by the drill unit 431 slides from the groove at the top of the interior part into the drain plate 370, and then the coolant is recovered;

[0059] After the processing is completed, the fourth servo motor 410 is controlled to make the processing assembly 430 move away from the processed interior parts. At this time, the electric push rod 340 is started again to make the U-shaped claw 341 approach the first fixed block 330. Similarly, the rotating arm 230 slides from the middle of the second guide groove 350 to the second rack 351 to engage with the first gear 220. Under the action of the second rack 351, the rotating arm 230 drives the clamping unit 240 to rotate to the side away from the drill unit 431. When the rotating arm 230 slides to the appropriate position on the other side of the feeding table 310, the third servo motor 320 is controlled to make the electric push rod 340 move away The rotating arm 230 is separated from the bottom of the processed interior decoration part, and the electric push rod 340 is controlled again to make the U-shaped claw 341 move again toward the first fixed block 330. After disengaging from the rotating arm 230, the staff pulls out the processed interior decoration part in the clamping unit 240 and takes away the clamping mechanism 200 after processing. Similarly, the second servo motor 180 is controlled to make the push plate 182 push the next rotating arm 230 to the inside of one end of the second guide groove 350, and similarly, the third servo motor 320 and the electric push rod 340 are controlled to displace the clamping unit 240 at one end of the next rotating arm 230 for post-processing.
