Description

Technical Field

[0001] This invention relates to the field of automotive parts production and conveying technology, specifically to a conveying device for automotive parts production and its usage method. Background Technology

[0002] In the process of automobile manufacturing, it is necessary to transport the processed parts between various processing machines. This allows for the convenient transport and processing of automobile parts and components within each processing machine. When washing automobile parts during production, the parts need to be transported and cleaned using a conveying device.

[0003] For example, an automotive parts conveying device with publication number CN119349183A uses a limiting structure to limit the conveying of parts from both sides, creating a more precise limiting effect. This facilitates subsequent automated drilling processes. However, in actual use, automotive parts are typically conveyed and cleaned via a conveyor belt. During this process, it is not convenient to flip the parts or thoroughly rinse them. For instance, when rinsing and flipping precision automotive parts (such as those in engines and transmissions), friction can easily occur between the parts and the conveyor belt. Metal debris adhering to the surface of the parts during rinsing may fall onto the top of the conveyor belt. When flipping the parts, the movement between the parts and the conveyor belt can cause friction between the parts and the metal debris, potentially scratching the surface of the precision parts and affecting their production quality. This presents certain defects in its use.

[0004] Therefore, we propose a conveying device for automotive parts production and its usage method to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a conveying device and its usage method for automotive parts production, in order to solve the problems mentioned in the background art, which typically involves conveying parts via conveyor belts. During the conveying process, it is not convenient to turn the parts over or to thoroughly wash them. For example, when washing and turning over precision automotive parts (such as parts in engines and transmissions), friction can easily occur between the parts and the conveyor belt, which can easily cause scratches on the surface of the precision parts and affect the production quality of the precision parts.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveying device for automobile parts production, including a workbench, a support frame symmetrically installed at the bottom of the workbench, and upright plates symmetrically installed at the top of the workbench, and two sets of rotating rollers symmetrically rotatably connected between the two upright plates, while a conveyor belt is rotatably connected to the outside of the two sets of rotating rollers.

[0019] By adopting the above technical solution, the downward movement of the moving rod can drive the movable plate to move downward as well.

[0020] Preferably, a movable plate is fixedly installed at the bottom of the movable plate, and a positioning frame is fixedly installed on one side of the inside of the rotating frame. The movable frame is symmetrically slidably connected inside the positioning frame. Meanwhile, a sloping groove is opened through one side of the movable plate, and a column block is fixedly installed between the two movable frames. The column block is slidably connected to the sloping groove.

[0021] By adopting the above technical solution, the downward movement of the movable plate can drive the movable frame to move.

[0022] Preferably, a mounting plate is fixed on one side of each of the two movable frames, and the mounting plate is symmetrically slidably connected with columns.

[0027] By adopting the above technical solution, the movement of the connecting plate is supported and limited.

[0028] Compared with the prior art, the beneficial effects of the present invention are: the conveying device for automobile parts production and its method of use can fix the parts without pushing the parts to move during the fixing process, avoid the parts from moving during the flipping process, prevent the parts from shifting and rubbing during the washing and flipping process, prevent damage to precision parts during the conveying of precision parts, and improve the conveying quality.

[0029] 1. When washing automotive parts, the parts are placed on a conveyor belt. A motor drives a rotating roller, causing the conveyor belt to rotate and transport the parts. During transport, the parts are washed by the washing equipment. After being moved, the parts enter the rotating frame, where they contact the rubber pads on the limit plate. This allows one side of the part to push against the limit plate, causing a movable rod to slide on the rotating frame and stretch a telescopic spring. The spring's elasticity coefficient should not be too high. At this point, the operator can stop the conveyor belt, ensuring the part pushes against the limit plate before stopping the belt. This prevents the conveyor belt from stopping too late, which could cause friction between the part and the belt, potentially damaging delicate parts. Afterwards, the electric pneumatic system can be controlled... The cylinder retracts, allowing the sliding rod to move. The sliding rod then moves the movable block, which slides on the fixed rod, causing the positioning plate to move. After the positioning plate moves, it causes the crossbar to slide on the guide frame. The moving rod moves laterally and downwards, causing the positioning plate to move downwards and to one side of the part. Then, the crossbar moves to the straight position of the guide frame. The positioning plate then moves, allowing the sponge pad to contact the part. The positioning plate and the limiting plate can fix the part in place without pushing it during the fixing process. This prevents the part from moving during the flipping process, avoids displacement and friction during rinsing and flipping, and prevents damage to precision parts during transport, thus improving the transport quality.

[0030] 2. During the downward movement of the positioning plate driven by the moving rod, the telescopic rod can also be moved downward, which in turn moves the movable plate downward. The movable plate moves downward, which in turn moves the movable plate and can slide on the positioning rod for limiting. After the movable plate moves, it can push the column block to move through the sliding connection between the inclined groove and the column block, which in turn moves the moving frame and the positioning sleeve, so that the positioning sleeve fits against the movable rod. Then, the moving frame continues to move, which can push the mounting plate to move, so that the column rod slides on the mounting plate, which can stretch the return spring. The reaction force of the return spring makes the positioning sleeve fit tightly against the movable rod, which can reliably position the movable rod. Afterward, the movement of the moving rod can cause the telescopic rod to retract, which can prevent the limiting plate from moving when fixing the parts and avoid unnecessary friction damage to the parts.

[0031] 3. After the parts are fixed, the hydraulic push rod can be activated to move the connecting plate downward. During the downward movement of the connecting plate, the support block slides on the limit rod to limit the movement of the connecting plate. Then, through the movement of the connecting plate, the toothed plate meshes with the rotating gear to drive the rotating shaft to rotate, which in turn rotates the rotating frame, allowing the parts to be flipped. After the rotating frame rotates half a revolution, it will not collide with the rotating roller, and the protruding parts on the rotating frame can extend between the conveyor belt and the vertical plate, thus facilitating the flipping of the parts.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1-9 The present invention provides a technical solution: a conveying device for automobile parts production, including a workbench 1, a support frame 101 symmetrically installed at the bottom of the workbench 1, and a vertical plate 102 symmetrically installed at the top of the workbench 1, and two sets of rotating rollers 103 symmetrically rotatably connected between the two vertical plates 102, and a conveyor belt 104 rotatably connected to the outside of the two sets of rotating rollers 103.

[0044] Also includes:

[0045] The fixing component 2 is disposed above the two sets of rotating rollers 103, and the fixing component 2 includes a rotating frame 201;

[0046] A rotating frame 201 is positioned above and between two sets of rotating rollers 103. The rotating frame 201 has movable rods 202 symmetrically slidably connected inside. One end of each movable rod 202 is fixedly mounted with a limiting plate 203, and a rubber pad 204 is fixedly mounted on one side of the limiting plate 203. Meanwhile, a fixing plate 205 is fixedly mounted on the other end of each movable rod 202. Furthermore, a telescopic spring 206 is sleeved on the outside of each movable rod 202 on one side of the fixing plate 205, and both ends of the telescopic spring 206 are fixedly connected to the fixing plate 205 and the rotating frame 201, respectively.

[0047] The fixed frame 207 is symmetrically installed on the top two sides of the rotating frame 201. A fixed rod 208 is fixedly installed between each pair of fixed frames 207, and movable blocks 209 are slidably connected to the outside of the two fixed rods 208. A fixed sleeve 210 is fixedly installed on the side of the two movable blocks 209 that are close to each other.

[0048] The interior of each of the two fixed sleeves 210 is slidably connected with a moving rod 211, and a positioning plate 212 is fixedly installed on the side of the two moving rods 211 that are close to each other. A sponge pad 213 is fixedly installed on one side of the positioning plate 212. At the same time, a mounting bracket 214 is fixedly installed on the top of each set of two fixed brackets 207, and a guide bracket 215 is fixedly installed between each set of two mounting brackets 214.

[0049] A crossbar 216 is fixedly installed above the side of each of the two movable rods 211 near the guide frame 215, and the crossbar 216 is slidably connected to the guide frame 215.

[0050] A sliding rod 217 is fixedly installed on one side of the movable block 209, and the sliding rod 217 is slidably connected to the fixed frame 207 on one side. A positioning seat 218 is fixedly installed on the top side of the rotating frame 201, and an electric cylinder 219 is fixedly installed on the upper part of the inside of the positioning seat 218. The movable end of the electric cylinder 219 is fixedly connected to the sliding rod 217.

[0051] Example 1: As Figures 1-6As shown, when washing automotive parts, the parts are placed on the conveyor belt 104. A motor drives the rotating roller 103 to rotate, causing the conveyor belt 104 to rotate and transport the parts. During transport, the parts are washed by the washing equipment on the conveyor belt 104. After being transported and moved, the parts can enter the interior of the rotating frame 201, allowing the parts to contact the rubber pad 204 on the limiting plate 203. This allows one side of the part to push against the limiting plate 203, causing the movable rod 202 to slide on the rotating frame 201 and stretch the telescopic spring 206. The elastic coefficient of the telescopic spring 206 is not too large. At this point, the operator can stop the operation of the conveyor belt 104, ensuring the parts push against the limiting plate 203 before stopping the conveyor belt 104. This prevents the conveyor belt 104 from stopping too late, which could cause friction between the parts and the conveyor belt 104, thus avoiding damage to delicate parts. Afterwards, the electric cylinder can be controlled. 219 retracts, allowing the sliding rod 217 to move. The sliding rod 217 then moves the movable block 209, which slides on the fixed rod 208, causing the positioning plate 212 to move. After the positioning plate 212 moves, it causes the crossbar 216 to slide on the guide frame 215, allowing the moving rod 211 to move laterally and downward, causing the positioning plate 212 to move downward and to one side of the part. Then, the crossbar 216 moves to the straight position of the guide frame 215. The movement of the positioning plate 212 allows the sponge pad 213 to contact the part. The positioning plate 212 and the limiting plate 203 can fix the part, and the part will not be pushed to move during the fixing process. This prevents the part from moving during the flipping process, avoids displacement and friction during the washing and flipping process, prevents damage to the precision parts during the transport of precision parts, and improves the transport quality.

[0052] Two movable rods 211 are fixedly installed with telescopic rods 220 on one side below the fixed sleeve 210. A movable plate 221 is fixedly installed at the end of the telescopic rod 220 away from the fixed sleeve 210. A positioning rod 222 is slidably connected to the inside side of the movable plate 221. At the same time, a limit block 224 and a limit frame 223 are fixedly installed at both ends of the positioning rod 222, and the limit block 224 and the limit frame 223 are both fixedly connected to the rotating frame 201.

[0053] A movable plate 225 is fixedly installed at the bottom of the movable plate 221, and a positioning frame 226 is fixedly installed on one side of the inside of the rotating frame 201. A movable frame 227 is symmetrically slidably connected inside the positioning frame 226. Meanwhile, a slanted groove 228 is opened through one side of the movable plate 225, and a column block 229 is fixedly installed between the two movable frames 227. The column block 229 is slidably connected to the slanted groove 228.

[0054] Two movable frames 227 are fixedly mounted on one side with a plate 230, and the inside of the mounting plate 230 is symmetrically slidably connected with a column rod 231. The outer side of each column rod 231 is fitted with a return spring 232. The two ends of the return spring 232 are fixedly connected to the mounting plate 230 and the column rod 231 respectively. A positioning sleeve 233 is fixedly installed at one end of each column rod 231, and a number of rubber protrusions are fixedly installed on one side of the positioning sleeve 233.

[0055] Example 2: Figures 2-4 and Figures 7-8 As shown, during the downward movement of the positioning plate 212 driven by the moving rod 211, the telescopic rod 220 can also be moved downward, which in turn moves the movable plate 221 downward. The downward movement of the movable plate 221 can move the movable plate 225, which can slide on the positioning rod 222 for limitation. After the movable plate 225 moves, it can push the column block 229 to move through the sliding connection between the inclined groove 228 and the column block 229, which can move the moving frame 227, which can move the positioning sleeve 233, so that the positioning sleeve 233 and the movable rod 222... After the 02 is fitted, the moving frame 227 continues to move, which can push the mounting plate 230 to move, so that the column rod 231 slides on the mounting plate 230, which can stretch the return spring 232. Through the reaction force of the return spring 232, the positioning sleeve 233 is pressed tightly against the movable rod 202, which can reliably position the movable rod 202. Then, the movement of the moving rod 211 can cause the telescopic rod 220 to retract, thereby preventing the limiting plate 203 from moving when fixing the part and avoiding unnecessary friction damage to the part.

[0056] The flipping component 3 is located on both sides of the rotating frame 201;

[0057] The flipping assembly 3 includes rotating shafts 301 symmetrically installed on both sides of the rotating frame 201, and the two rotating shafts 301 are rotatably connected to the two upright plates 102 respectively. One end of one rotating shaft 301 passes through one upright plate 102 and is fixedly installed with a rotating gear 302. Meanwhile, a fixed seat 303 is fixedly installed on the lower front side of one upright plate 102. A hydraulic push rod 304 is fixedly installed inside the fixed seat 303. A connecting plate 305 is fixedly installed on the movable end of the hydraulic push rod 304. A toothed plate 306 is fixedly installed on one side of the connecting plate 305. The toothed plate 306 is meshed with the rotating gear 302.

[0058] A support block 307 is fixedly installed on the other side of the connecting plate 305, and a limit rod 308 is fixedly installed inside the support block 307. Both ends of the limit rod 308 are fixedly installed with connecting blocks 309, and both connecting blocks 309 are fixedly connected to the upright plate 102.

[0059] Example 3: Figures 1-2 and Figure 9 As shown, after the parts are fixed, the hydraulic push rod 304 can be activated to drive the connecting plate 305 to move downward. During the downward movement, the connecting plate 305 drives the support block 307 to slide on the limit rod 308, which limits the movement of the connecting plate 305. Then, through the movement of the connecting plate 305, the toothed plate 306 meshes with the rotating gear 302 to drive the rotating shaft 301 to rotate, which causes the rotating frame 201 to rotate, allowing the parts to be flipped. After the rotating frame 201 rotates half a revolution, it will not collide with the rotating roller 103, and the protruding parts on the rotating frame 201 can extend between the conveyor belt 104 and the vertical plate 102, thus facilitating the flipping of the parts.

[0060] Working principle: When using this conveyor device for automotive parts production, firstly, according to... Figures 1-9 As shown, when washing automotive parts, the parts are placed on the conveyor belt 104. A motor drives the rotating roller 103 to rotate, causing the conveyor belt 104 to rotate and transport the parts. During transport, the parts are washed by a washing device on the conveyor belt 104. After the parts have moved, they can enter the rotating frame 201, allowing them to contact the rubber pad 204 on the limiting plate 203. This allows one side of the part to push against the limiting plate 203, causing the movable rod 202 to slide on the rotating frame 201 and stretch the telescopic spring 206. The elastic coefficient of the telescopic spring 206 is not too large. At this point, the operator can stop the conveyor belt 104, ensuring the part pushes against the limiting plate 203 before stopping the conveyor belt 104, preventing the part from getting stuck on the conveyor belt 104 due to delayed stopping. Friction is generated between the upward movement and the conveyor belt 104 to avoid damage to the more delicate parts. Then, the electric cylinder 219 can be controlled to retract, which can drive the sliding rod 217 to move. The sliding rod 217 can drive the movable block 209 to move, so that the movable block 209 slides on the fixed rod 208, which can drive the positioning plate 212 to move. After the positioning plate 212 moves, it can drive the crossbar 216 to slide on the guide frame 215, so that the moving rod 211 can move laterally and downward at the same time, so that the positioning plate 212 moves downward and moves to one side of the part. Then the crossbar 216 reaches the straight part of the guide frame 215. Then, the movement of the positioning plate 212 can make the sponge pad 213 contact the part. The positioning plate 212 and the limiting plate 203 can fix the part.

[0061] During the downward movement of the positioning plate 212 driven by the moving rod 211, the telescopic rod 220 can also be moved downward, which in turn moves the movable plate 221 downward. The downward movement of the movable plate 221 can move the moving plate 225, which can slide on the positioning rod 222 for limitation. After the moving plate 225 moves, it can push the column block 229 to move through the sliding connection between the inclined groove 228 and the column block 229, which can move the moving frame 227, which can move the positioning sleeve 233, so that the positioning sleeve 233 fits against the movable rod 202. Then, the moving frame 227 continues to move, which can push the mounting plate 230 to move, so that the column rod 231 slides on the mounting plate 230, which can stretch the return spring 232. The reaction force of the return spring 232 makes the positioning sleeve 233 tightly fit against the movable rod 202, which can reliably fix the movable rod 202. After the moving rod 211 moves, the telescopic rod 220 can retract, thus preventing the limiting plate 203 from moving when fixing the part and avoiding unnecessary friction damage to the part. After fixing the part, the hydraulic push rod 304 can be activated to drive the connecting plate 305 to move downward. During the downward movement of the connecting plate 305, the support block 307 slides on the limiting rod 308 to limit the movement of the connecting plate 305. Then, through the movement of the connecting plate 305, the toothed plate 306 meshes with the rotating gear 302 to drive the rotating shaft 301 to rotate, causing the rotating frame 201 to rotate, which can make the part flip. After the rotating frame 201 rotates half a turn, it will not collide with the rotating roller 103, and the protruding parts on the rotating frame 201 can extend between the conveyor belt 104 and the vertical plate 102, thus facilitating the flipping of the part.

7. A method of using a conveying device for automobile parts production, comprising the conveying device for automobile parts production as described in claim 6, characterized in that, The specific usage steps are as follows: Step 1: When washing automotive parts, the parts are placed on a conveyor belt (104). A motor drives a rotating roller (103) to rotate, causing the conveyor belt (104) to rotate and transport the parts. During the transport process, the parts on the conveyor belt (104) are washed by a washing device. After the parts are transported and moved, they enter the interior of a rotating frame (201), causing the parts to contact the rubber pad (204) on the limiting plate (203). This causes one side of the parts to push against the limiting plate (203), moving it and causing the movable rod (202) to slide on the rotating frame (201) and stretch the telescopic spring (206). The elastic coefficient of the telescopic spring (206) is not too large. At this time, the operator stops the operation of the conveyor belt (104), so that the parts push against the limiting plate (203) before stopping the conveyor belt (104), avoiding the parts being stuck on the conveyor belt (104) due to stopping the conveyor belt (104) too late. Friction is generated between the moving part and the conveyor belt (104) to avoid damage to the more delicate parts. Then, the electric cylinder (219) is retracted, which drives the sliding rod (217) to move. The sliding rod (217) drives the movable block (209) to move, which makes the movable block (209) slide on the fixed rod (208), which drives the positioning plate (212) to move. After the positioning plate (212) moves, it drives the crossbar (216) to slide on the guide frame (215), which makes the moving rod (211) move laterally and move downward, which makes the positioning plate (212) move downward, which makes the positioning plate (212) move to one side of the part. Then the crossbar (216) moves to the straight part of the guide frame (215). Then the positioning plate (212) moves to make the sponge pad (213) contact the part, and the positioning plate (212) and the limiting plate (203) fix the part. Step Two: During the downward movement of the moving rod (211) and the positioning plate (212), the telescopic rod (220) is also moved downward, which in turn causes the movable plate (221) to move downward. The downward movement of the movable plate (221) causes the moving plate (225) to move and slide on the positioning rod (222) for limitation. After the moving plate (225) moves, it pushes the column block (229) to move through the sliding connection between the inclined groove (228) and the column block (229), which in turn causes the moving frame (227) to move, which in turn causes the positioning sleeve (233) to move. The movement causes the positioning sleeve (233) to fit against the movable rod (202). Then, the moving frame (227) continues to move, pushing the mounting plate (230) to move, causing the column rod (231) to slide on the mounting plate (230), which stretches the return spring (232). Through the reaction force of the return spring (232), the positioning sleeve (233) is pressed tightly against the movable rod (202), reliably positioning the movable rod (202). Then, the movement of the moving rod (211) causes the telescopic rod (220) to retract. Step 3: After the parts are fixed, the hydraulic push rod (304) is activated to drive the connecting plate (305) to move downward. During the downward movement, the connecting plate (305) drives the support block (307) to slide on the limit rod (308) to limit the movement of the connecting plate (305). Then, through the movement of the connecting plate (305), the toothed plate (306) meshes with the rotating gear (302) to drive the rotating shaft (301) to rotate, causing the rotating frame (201) to rotate, so that the parts are flipped. After the rotating frame (201) rotates half a turn, it will not collide with the rotating roller (103), and the protruding parts on the rotating frame (201) extend into the space between the conveyor belt (104) and the upright plate (102), which facilitates the flipping of the parts.
