[0014] An automatic milling device and process for automobile grille mold frame includes the following steps:

[0015] S1: When using this device, first install the device at the designated position of the production line, then place the automobile grille mold frame to be processed on the support table, and then start the hydraulic pump, which can drive two push plates one and two push plates two to position the automobile grille mold frame;

[0016] S2: When push plate 1 and push plate 2 have moved to the final position, the hydraulic pump continues to push the pressure plate 1, the clamping column will be pushed upward, the two clamping plates will also move towards each other, the elastic airbag will expand, and then the automobile grille mold frame will be fixed and limited;

[0017] S3: After the processing is completed, the hydraulic pump continues to push the pressure plate 1 to the back, the sliding shell will move upward, the gear shaft will mesh with the rack 2, and as the sliding shell continues to move upward, the fixed automobile grille mold frame will be flipped.

[0018] The present invention has the following beneficial effects:

[0019] 1. The present invention utilizes a pressing plate 1 to move compressed air, and the thrust generated by the compressed air pushes the pushing plate 1 and the pushing plate 2, thereby positioning the automobile grille mold frame. Specifically, the hydraulic pump is started, and the hydraulic pump drives the pressing plate 1 to move, thereby pushing the air in the sealing shell into the air guide hose 1, and the air guide hose 1 passes the air through the interior of the support platform and finally passes into the fixed box 1, and the air passed into the fixed box 1 will push the pressing plate 2, thereby pushing the two pushing plates 1 in a direction close to each other, and the air passed into the fixed box 1 will also pass into the fixed box 2 through the air guide hose 2, and the air passed into the fixed box 2 will push the pressing plate 3, thereby pushing the two pushing plates 2 in a direction close to each other, and positioning the automobile grille mold frame through forces in four directions, and when the pushing plate 1 and the pushing plate 2 are both moved to the final position, the automobile grille mold frame placed on the support platform will be pushed to the top of the storage plate to complete the positioning, and this design can position the automobile grille mold frame through the action of the pushing plate 1 and the pushing plate 2, and no manual intervention is required, thereby saving the time and cost of manual operation and improving production efficiency.

[0020] 2. When the automobile grille mold frame is pushed onto the storage plate, it indicates that the push plate 1 and the push plate 2 have moved to the final position. At this time, the hydraulic pump continues to push the pressure plate 1, and the air will squeeze the sealing rod 1, thereby pushing the sealing rod 1 away from the fixing box 1 and compressing the spring 2. At this time, the air will enter the fixing sleeve 1 and enter the air guide hose 4 through the air guide hose 3. The air guide hose 4 will pass the air in the fixing sleeve 2 and push the clamping column upward, thereby clamping the clamping column in the automobile grille mold frame to prevent it from moving during the milling process. When the hydraulic pump drives the pressure plate 1 to perform the re-engraving, the pressure plate 1 will be pressed to the fixed box 1. When the push plates 1 and 2 are in the same position, the air introduced into the fixing box 1 and the fixing box 2 will be sucked out, thereby driving the push plates 1 and 2 to reset. After the reset of the push plates 1 and 2 is completed, as the pressure plate 1 continues to move toward the front, the sealing rod 2 will be sucked away from the fixing sleeve 1 and compress the spring 3. At this time, the air introduced into the air guide hose 4 can be sucked back through the connecting pipe. This design can limit the automobile grille mold frame through the clamping column and the support platform, so that the automobile grille mold frame is firmly fixed on the equipment to prevent movement or shaking during the processing, thereby ensuring the processing accuracy and quality.

[0021] 3. In the present invention, the air introduced into the fixing sleeve 2 will also enter the fixing seat through the air guide hose 5. The air entering the fixing seat will push the two clamps towards each other through the air guide cavity, so as to limit the upper part of the automobile grille mold frame. When the clamp is pushed to the final position, as the air continues to be introduced into the fixing seat, the air will enter the elastic airbag through the inflation hole, thereby expanding the elastic airbag, filling the gap between the clamp and the automobile grille mold frame, and further stabilizing the automobile grille mold frame. This design can limit the upper part of the automobile grille mold frame by setting the clamp, and provide uniform fixing pressure to the automobile grille mold frame through the expansion of the elastic airbag, thereby ensuring that the automobile grille mold frame is in a stable position during the processing, and will not cause scratches on the surface of the automobile grille mold frame, thereby preventing the automobile grille mold frame from vibrating up and down during the processing, resulting in inaccurate processing position.

[0022] 4. After the processing is completed, the hydraulic pump continues to push the pressure plate 1 to the back side. At this time, the sliding rod will block the air guide hose 1, and the thinner part of the semi-sealing rod will also slide to the position previously in contact with the sealing shell, so that the pressure plate 1 continues to move and the air will not be passed into the air guide hose 1. The movement of the pressure plate 1 to the back side will drive the rack 1 to move to the back side through the connecting rod, so that the rack 1 is meshed with the gear. As the rack 1 continues to move, it will drive the threaded rod to rotate through the gear. The rotation of the threaded rod will drive the extrusion block to move in the direction away from the sealing shell. The extrusion block will move the sliding shell upward along the inclined surface of the extrusion block through the extrusion roller. The sliding shell is rising. During the process, the fixed shaft and the storage plate will be driven to move upward together. After the sliding shell moves upward to a certain distance, the gear shaft will mesh with the rack 2. As the sliding shell continues to move upward, the gear shaft will rotate during the rising process. The rotation of the gear shaft will drive the fixed shaft and the storage plate to rotate through the synchronous belt, thereby turning over the fixed automobile grille mold frame. This design can pour out the milling fluid and debris left in the groove at the milling location of the automobile grille mold frame during the milling process, thereby automatically cleaning the automobile grille mold frame, reducing manual operations while facilitating subsequent processing, painting or assembly processes, thereby improving production efficiency and quality.

As the rack 402 continues to move, it will drive the threaded rod 404 to rotate through the gear 403. The rotation of the threaded rod 404 will drive the extrusion block 405 to move away from the sealing shell 104. The extrusion block 405 will make the sliding shell 407 move upward along the inclined surface of the extrusion block 405 through the extrusion roller 409. The sliding shell 407 will drive the fixed shaft 410 and the storage plate 102 to move upward during the rising process. After the sliding shell 407 moves upward to a certain distance , the gear shaft 412 will mesh with the rack 2 413, and as the sliding shell 407 continues to move upward, the gear shaft 412 will rotate during the rising process. The rotation of the gear shaft 412 will drive the fixed shaft 410 and the storage plate 102 to rotate together through the synchronous belt 411, thereby turning over the fixed automobile grille mold frame. This design can pour out the milling fluid and debris left in the groove of the milling part of the automobile grille mold frame during the milling process, and then automatically clean the automobile grille mold frame, reducing manual operations while facilitating subsequent processing, painting or assembly processes, thereby improving production efficiency and quality.

[0046] The process of the milling equipment includes the following steps:

[0047] S1: When using the device, first install the device at a designated position of the production line, then place the automobile grille mold frame to be processed on the support table 101, and then start the hydraulic pump 103, which can drive two push plates 112 and two push plates 2 116 to position the automobile grille mold frame;

[0048] S2: When the push plate 112 and the push plate 2 116 have moved to the final position, the hydraulic pump 103 continues to push the pressure plate 105, the clamping column 211 will be pushed upward, the two clamping plates 304 will also move towards each other, and the elastic airbag 306 will expand, thereby fixing and limiting the automobile grille mold frame;

[0049] S3: After the processing is completed, the hydraulic pump 103 continues to push the pressure plate 105 to the back, the sliding shell 407 will move upward, the gear shaft 412 will mesh with the rack 2 413, and as the sliding shell 407 continues to move upward, the fixed automobile grille mold frame will be flipped.

[0050] A specific application of the present embodiment is as follows: when using the present device, the device is first installed at a designated position of the production line, and then the automobile grille mold frame to be processed is placed on the support platform 101, and then the hydraulic pump 103 is started, the hydraulic pump 103 will drive the pressing plate 105 to move, and then push the air in the sealing shell 104 into the air guide hose 109, the air guide hose 109 will pass the air through the interior of the support platform 101 and finally into the fixed box 110, the air passed into the fixed box 110 will push the pressing plate 2 111, and then the two pushing plates 112 can be pushed towards each other, the air passed into the fixed box 110 will also pass into the fixed box 2 114 through the air guide hose 2 113, and the air passed into the fixed box 2 114 The air will push the pressure plate three 115, and then the two push plates two 116 can be pushed towards each other. Through the forces in four directions, the automobile grille mold frame is positioned. When the push plate one 112 and the push plate two 116 are moved to the final position, the automobile grille mold frame placed on the support platform 101 will be pushed to the top of the storage plate 102 to complete the positioning. This design can position the automobile grille mold frame through the action of the push plate one 112 and the push plate two 116, and no manual intervention is required, thereby saving the time and cost of manual operation and improving production efficiency. When the automobile grille mold frame is pushed onto the storage plate 102, it means that the push plate one 112 and the push plate two 116 have moved to the final position. At this time, the hydraulic pump 103 continues to push the pressure plate one 105 , the air will squeeze the sealing rod 1 203, thereby pushing the sealing rod 1 203 away from the fixed box 1 110 and compressing the spring 204. At this time, the air will enter the fixed sleeve 1 201 and enter the air guide hose 4 209 through the air guide hose 3 205. The air guide hose 4 209 will pass the air therein into the fixed sleeve 210 and push the clamping column 211 upward, thereby causing the clamping column 211 to be stuck in the automobile grille mold frame to prevent it from moving during the milling process. When the hydraulic pump 103 drives the pressure plate 1 105 to reset, the air passed into the fixed box 1 110 and the fixed box 2 114 will be sucked out, thereby driving the push plate 1 112 and the push plate 2 116 to reset. When the push plate 1 112 and the push plate 2 116 are reset, as the pressure plate 1 1 05 continues to move toward the front, the sealing rod 207 will be sucked away from the fixing sleeve 1 201 and the spring 3 208 will be compressed. At this time, the air passed into the air guide hose 4 209 can be sucked back through the connecting pipe 206. This design can limit the automobile grille mold frame through the clamping column 211 and the support platform 101, so that the automobile grille mold frame is firmly fixed on the equipment to prevent movement or shaking during the processing, thereby ensuring the processing accuracy and quality. In the above process, the air passed into the fixing sleeve 210 will also enter the fixing seat 302 through the air guide hose 5 301. The air entering the fixing seat 302 will push the two clamping plates 304 towards each other through the air guide cavity 303, thereby limiting the upper part of the automobile grille mold frame.When the card plate 304 is pushed to the final position, as air is continuously introduced into the fixing seat 302, the air will enter the elastic airbag 306 through the inflation hole 305, thereby expanding the elastic airbag 306, filling the gap between the card plate 304 and the automobile grille mold frame, and further stabilizing the automobile grille mold frame. This design can limit the upper part of the automobile grille mold frame by setting the card plate 304, and provide uniform fixing pressure to the automobile grille mold frame through the expansion of the elastic airbag 306, thereby ensuring that the automobile grille mold frame is in a stable position during the processing, and will not cause damage to the surface of the automobile grille mold frame. Scratches are formed to prevent the automobile grille mold frame from vibrating up and down during processing, resulting in inaccurate processing positions. After the clamping is completed, the hydraulic pump 103 is controlled to stop running. At this time, the automobile grille mold frame can be milled. After the processing is completed, the hydraulic pump 103 continues to push the pressing plate 105 to the back. At this time, the sliding rod 107 will block the air hose 109, and the thinner part of the semi-sealing rod 106 will also slide to the position where it was previously in contact with the sealing shell 104, so that the pressing plate 105 continues to move without passing air into the air hose 109. The pressing plate 105 moves to the back through the connection The rod 401 drives the rack 1 402 to move to the back side, so that the rack 1 402 meshes with the gear 403. As the rack 1 402 continues to move, it drives the threaded rod 404 to rotate through the gear 403. The rotation of the threaded rod 404 drives the extrusion block 405 to move away from the sealing shell 104. The extrusion block 405 drives the sliding shell 407 to move upward along the inclined surface of the extrusion block 405 through the extrusion roller 409. The sliding shell 407 drives the fixed shaft 410 and the storage plate 102 to move upward during the rising process. After the sliding shell 407 moves upward to a certain distance, the gear 403 drives the threaded rod 404 to rotate. The threaded rod 404 rotates and drives the extrusion block 405 to move away from the sealing shell 104. The extrusion block 405 drives the sliding shell 407 to move upward along the inclined surface of the extrusion block 405 through the extrusion roller 409. The shaft 412 will mesh with the rack 413. As the sliding shell 407 continues to move upward, the gear shaft 412 will rotate during the rising process. The rotation of the gear shaft 412 will drive the fixed shaft 410 and the storage plate 102 to rotate together through the synchronous belt 411, thereby turning over the fixed automobile grille mold frame. This design can pour out the milling fluid and debris left in the groove of the automobile grille mold frame during the milling process, and then automatically clean the automobile grille mold frame, reducing manual operations while facilitating subsequent processing, painting or assembly processes, thereby improving production efficiency and quality.
