With the improvement of people's living standards, people's consumption of cars is increasing, and the market for auto parts is getting bigger and bigger. In recent years, auto parts manufacturers are also developing rapidly. In the process of production, auto parts need to be welded with the help of welding equipment to meet the conditions for car use.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] The invention discloses an automobile parts welding machine which is mainly used for welding small automobile parts and nuts.

[0040] Reference Figure 1 and Figure 2 A welding machine for automobile parts comprises a frame assembly 1, wherein a feeding assembly 2 for conveying parts is arranged on the left side of the upper end of the frame assembly 1; a storage linkage mechanism 3 for storing unprocessed parts is arranged in the middle of the upper end of the frame assembly 1; a storage mechanism 4 for storing nuts is arranged on the right side of the upper end of the frame assembly 1; a rotary welding mechanism 5 for welding automobile parts is arranged on the rear side of the storage mechanism 4; a driving mechanism 6 for driving loading and unloading is arranged on the left side of the lower end of the frame assembly 1; a unloading assembly 7 for unloading spare parts is connected to the right side of the driving mechanism 6; a cleaning mechanism 8 for cleaning welding slag dust and purifying harmful gases is arranged on the right side of the unloading assembly 7, and the frame assembly 1 comprises a workbench 101, and a feeding trough 102 is opened through the middle of the workbench 101.

[0041] In this embodiment: first, a part of the small auto parts are placed in the material storage linkage mechanism 3, and a part of the nuts are placed in the storage mechanism 4 to play a pre-storage role. Then, the driving mechanism 6 is started to drive the feeding assembly 2 to push the auto parts previously prepared in the feeding trough 102 to move to the right. At the same time, the feeding assembly 2 drives the material storage linkage mechanism 3 to prepare for the next group of auto parts, so that a group of small parts in the material storage linkage mechanism 3 falls into the feeding trough 102, which is convenient for the feeding assembly 2 to push. When the driving mechanism 6 drives the feeding assembly 2, the driving mechanism 6 synchronously drives the unloading assembly 7. Unload a group of previously welded small auto parts on the unloading column 702 by rotating, and turn a group of free unloading columns 702 to the lower right side of the workbench 101 for easy placement of unprocessed parts. At this time, the feeding component 2 pushes the parts to the right until they are pushed to the upper end of the unloading column 702, and the feeding component 2 drives the storage linkage mechanism 3 in the process of linking the storage mechanism 4 to promote automatic feeding of nuts, ensuring that a group of nuts fall on the upper end of the parts pushed to the upper end of the unloading column 702. At this time, the nuts and parts are merged and welding is carried out. The rotary welding mechanism 5 is started to drive the laser gun 504 to weld the contact point between the nut and the component in a circle. During the welding process, the high temperature generates harmful gases and welding slag dust. Since the unloading column 702 is connected to the cleaning mechanism 8, the harmful gases are collected, purified and discharged by the air pump to ensure that the environmental air index is within a safe range and the physical and mental health of the staff is guaranteed. The welding slag dust is collected in a centralized manner to reduce the subsequent cleaning of waste slag one by one and ensure the normal operation of welding. After the welding of the nut and the component is completed, the driving mechanism 6 is started to synchronously drive the feeding component 2 and the unloading component 7. The feeding component 2 pushes the prepared parts to be loaded and drives the material storage linkage mechanism 3 to prepare for the next group of parts, and drives the material storage linkage mechanism 3 to drive the storage mechanism 4 to feed, and the unloading component 7 rotates and unloads the parts that have been dry-welded, and moves to a new group of unloading columns 702 to the lower right side of the workbench 101 for the next group of parts processing, thereby repeatedly processing continuously, and the staff only needs to intermittently add automobile parts and nuts to the inside of the material storage linkage mechanism 3 and the storage mechanism 4, without manually repeatedly placing the parts on the welding position, thereby reducing contact with welding and improving the safety of the staff.

[0042] In the first embodiment, considering the need for preparation and loading and pushing of spare parts, the specific operations are as follows: Reference Figure 1 , Figure 2 and Figure 3In a preferred embodiment, the feeding assembly 2 includes a pushing plate 201 slidably connected to the inside of the feeding trough 102, a square groove 202 is opened on the left side of the pushing plate 201, and a movable rod 203 is arranged inside the square groove 202, and the material storage linkage mechanism 3 includes a material storage box 301 arranged in the middle of the upper end of the workbench 101, and the material storage box 301 is penetrated by the material storage trough 302, and the sliding rod 303 is slidably connected to the front and rear ends of the lower part of the material storage box 301, and the outer surface of the sliding rod 303 is wound with a first spring 304, and the first spring 304 is inside the material storage box 301, and a limiting plate 305 is connected to the right side of the sliding rod 303, and a connecting rod 306 is connected to the front and rear ends of the right side below the limiting plate 305, and a top column 308 is arranged at the front and rear ends of the upper right side of the limiting plate 305, and a partition plate 307 is connected to the middle part of the right side of the limiting plate 305, and a sliding groove 103 is opened at the front and rear ends of the upper middle part of the workbench 101.

[0043] When the loading of spare parts is required, the rotating movable rod 203 moves in a circular motion in the square groove 202, prompting the pushing plate 201 to push the feeding groove 102 to the right, and the spare parts prepared in the feeding groove 102 are pushed to the right. During the pushing process, the right front end of the pushing plate 201 contacts the connecting rod 306, prompting the connecting rod 306 to slide to the right along the slide groove 103 on the workbench 101, thereby driving the limiting plate 305 and the sliding rod 303 to slide to the right in the material storage box 301, and the first spring 304 on the outer surface of the sliding rod 303 is contracted by the sliding rod 303 sliding to the right. At the same time, the limiting plate 305 synchronously drives the partition plate 307 and the top column 308 to move to the right. At this time, the lower end of the material storage groove 302 inside the material storage box 301 is opened, and the parts stored in the material storage groove 302 fall down and fall on the upper surface of the pushing plate 201. At this time, the right front end of the pushing plate 201 After the spare parts pushed from the end are in place, the movable rod 203 moves in a circle in the square groove 202, and the push plate 201 moves to the left in the feeding trough 102. At that time, the resistance of the push plate 201 to the right of the connecting rod 306 disappears, and the sliding bar 303, the limit plate 305, the connecting rod 306, the partition plate 307 and the top column 308 are reset by the first spring 304, and the limit plate 305 moves to the left at the lower end of the storage box 301 to block the storage trough 302. At this time, the upper spare parts of the storage trough 302 are blocked, and one group falls on the upper end of the push plate 201. During the displacement of the push plate 201 to the left, the spare parts on the upper end of the push plate 201 are resisted by the workbench 101 and remain in place. Subsequently, after the push plate 201 is withdrawn, the spare parts fall into the feeding trough 102 and serve as the preparation spare parts to facilitate the processing of the push plate 201 when it is pushed to the right again.

[0044] In the first embodiment, the nut feed needs to be combined with the spare parts. Considering that a set of spare parts is matched with a set of nuts, the specific operation is as follows: Reference Figure 1 , Figure 4 and Figure 5 In a preferred embodiment, the storage mechanism 4 includes a storage column 401 connected to the right side of the storage box 301, a through groove 402 is opened in the middle of the storage column 401, a card slot 403 is opened at the lower left end of the storage column 401, a fixed plate 404 is arranged at the lower right end of the storage column 401, a sliding plate 405 is slidably connected to the middle of the fixed plate 404, a conduction rod 408 is connected to the front and rear ends of the left side of the sliding plate 405, a cylinder 407 is connected to the end of the conduction rod 408 away from the sliding plate 405, and a second spring 406 is connected to the right side of the cylinder 407.

[0045] In this embodiment, when the limit plate 305 synchronously drives the partition plate 307 and the top column 308 to move to the right, the partition plate 307 is clamped into the inner part of the card slot 403 on the storage column 401, and the through slot 402 inside the storage column 401 is blocked. At the same time, the top column 308 contacts the cylinder 407, causing the sliding plate 405 to move to the right, and the second spring 406 contracts. The through slot 402 originally blocked by the sliding plate 405 is opened, and the nut inside slides down and falls on the blocked partition plate 307. At this time, the partition plate 307 and the top column 308 move to the right. When the left reset displacement occurs, the top force of the cylinder 407 disappears, and the cylinder 407 and the sliding plate 405 are reset by the second spring 406, blocking the through groove 402, so that the upper thread cannot fall, and there is a set of nuts between the sliding plate 405 and the partition 307. After the partition 307 is pulled out of the slot 403, the set of nuts originally on the partition 307 slides down and combines with the spare parts. Therefore, when a set of spare parts is pushed, a set of nuts will fall down to match, thereby reducing the phenomenon of repeated picking up by staff and improving the automation effect of feeding.

[0046] In the first embodiment, considering that the nut needs to be welded to the spare part, the specific operation is as follows: Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the rotary welding mechanism 5 includes a wheel disc assembly 501 connected to the outer surface of the upper end of the storage column 401 by a bearing, a first motor 502 is connected to the lower rear end of the wheel disc assembly 501, a turntable 503 is connected to the lower front end of the wheel disc assembly 501, and a laser gun 504 is installed on the outer surface of the turntable 503.

[0047] In this embodiment: the first motor 502 is started to drive the law wheel set 501 to drive the turntable 503, so that the turntable 503 forms a circular rotation around the storage column 401, thereby driving the laser gun 504 to move, and performing a circle of high-temperature welding on the contact between the spare parts and the nuts.

[0048] In the first implementation, considering that the loading and unloading need to be driven in order to improve the automation effect, the specific operations are as follows: Reference Figure 1 and Figure 6 In a preferred embodiment, the driving mechanism 6 includes a small gear 601 connected to the lower end of the movable rod 203, the lower end of the small gear 601 is connected to the second motor 602, the right side of the small gear 601 is meshed with a large gear 603, the lower end of the large gear 603 is connected to a bevel gear set 604, and the right side of the bevel gear set 604 is connected to a rotating shaft 605.

[0049] In this embodiment: first, the second motor 602 is started to drive the small gear 601 to drive the movable rod 203 to move in a circle, so that the pushing plate 201 can be displaced left and right in the feeding trough 102 to push the material. At the same time, the small gear 601 synchronously drives the large gear 603 to drive the bevel gear set 604 to rotate the linkage shaft 605, so as to cause the outer cylinder 701 to rotate, thereby realizing the position change of multiple groups of unloading columns 702, and rotating and pushing the processed parts on the unloading columns 702 to unload the materials, and rotating the remaining unloading columns 702 to the processing position at the lower right side of the workbench 101 for subsequent processing of parts.

[0050] In the first embodiment, considering that the spare parts and nuts need to be placed in a certain position for welding, the specific operations are as follows: Reference Figure 1 , Figure 6 and Figure 7 In a preferred embodiment, the material discharge component 7 includes an outer cylinder 701 connected to the right side of the rotating shaft 605, a material discharge column 702 is arranged on the outer surface of the outer cylinder 701, a ventilation groove 703 is opened through the middle of the material discharge column 702, a fence 704 is arranged at the opening of the material discharge column 702 away from the outer cylinder 701, and a limiting protrusion 705 is fixedly connected in the middle of the fence 704.

[0051] In this embodiment: when the push plate 201 pushes the spare parts prepared by the feeding trough 102 to the right, the spare parts are pushed to the upper end of the bar grid 704 of the unloading column 702, and the circular hole on the spare parts is sleeved on the limiting protrusion 705, so that they are stably placed on the upper end of the bar grid 704. At the same time, the ventilation groove 703 is sucked at all times to play a certain adsorption effect, and the lower end of the storage column 401 is aligned with the limiting protrusion 705, so that the nut falls on the limiting protrusion 705 after sliding down, and is combined with the circular hole on the spare parts, which is convenient for finished product processing. After welding is completed, the rotating shaft 605 drives the outer cylinder 701 to rotate, The processed spare parts are rotated and pushed to the corresponding position of the through hole 803 on the inner cylinder 801. Another set of free unloading columns 702 are prepared to be processed by the next set of spare parts at the lower right side of the workbench 101. The processed spare parts are at the corresponding position of the through hole 803 on the inner cylinder 801. The air pump is used to suck the processed spare parts from the through hole 803 to ensure that the processed spare parts continue to have the adsorption effect, preventing the outer cylinder 701 from rotating and the angle of the unloading column 702 from changing, causing the processed spare parts to directly break away from the upper end of the fence 704 and fall from a high place and collide, resulting in the separation of the nut and the spare parts.

[0052] In the first embodiment, considering that welding slag dust and harmful gases generated during the welding of spare parts and nuts need to be processed, the specific operations are as follows: Reference Figure 1 and Figure 8 In a preferred embodiment, the cleaning mechanism 8 includes an inner cylinder 801 movably connected to the outer cylinder 701, a vent 802 is provided on the upper end of the left outer surface of the inner cylinder 801, a through hole 803 is provided on the rear side of the left outer surface of the inner cylinder 801, a purification net 804 is provided on the right side inside the inner cylinder 801, and a waste box 805 is connected to the right side of the lower end of the inner cylinder 801.

[0053] In this embodiment: during the high-temperature welding of spare parts and nuts by the laser gun 504, the generated welding slag dust and harmful gases are exhausted by the air pump, and enter the inner cylinder 801 through the ventilation slot 703 inside the unloading column 702 through the vent 802. At the same time, the air pump can suck the spare parts placed on the upper surface of the bar grid 704 above the unloading column 702, thereby increasing the stability of the placement. When the outer cylinder 701 is rotating with the unloading column 702, the inner cylinder 801 always remains stationary, thereby ensuring that only the unloading column 702 at the vent 802 on the outer cylinder 701 has a strong suction force. At this time, the welding slag dust and harmful gases enter the inner cylinder 801. After the harmful gases pass through the purification net 804, they are purified and discharged through the purification net 804, thereby ensuring the environmental safety of the working area and the physical and mental health of the staff. At the same time, the welding slag dust is blocked by the purification net 804 and falls into the waste box 805 for centralized collection, thereby ensuring the operation of the processing and reducing the subsequent manual cleaning phenomenon of the staff.

[0054] Among them, auto parts and nuts are shown as follows Fig. 9 shown.

[0055] Working principle: When in use, first place a part of the small auto parts in the storage linkage mechanism 3, and place a part of the nuts in the storage mechanism 4 to play a pre-storage role, then start the driving mechanism 6 to drive the feeding assembly 2 to push the auto parts previously prepared in the feeding trough 102 to move to the right, and at the same time, the feeding assembly 2 drives the storage linkage mechanism 3 to prepare for the next group of auto parts, so that a group of small parts in the storage linkage mechanism 3 falls into the feeding trough 102, which is convenient for the feeding assembly 2 to push, and when the driving mechanism 6 drives the feeding assembly 2, the driving mechanism 6 synchronously drives the unloading assembly Component 7, unload a group of previously welded small auto parts on the unloading column 702 by rotating, and turn a group of free unloading columns 702 to the lower right side of the workbench 101 for easy placement of unprocessed parts. At this time, the feeding component 2 pushes the parts to the right until they are pushed to the upper end of the unloading column 702, and the feeding component 2 drives the storage linkage mechanism 3 in the process of linking the storage mechanism 4 to promote automatic feeding of nuts, ensuring that a group of nuts fall on the upper end of the parts pushed to the upper end of the unloading column 702. At this time, the nuts and parts are merged and welding is carried out. , start the rotary welding mechanism 5 to drive the laser gun 504 to weld the contact point between the nut and the component in a circle. During the welding process, the high temperature produces harmful gases and welding slag dust. Since the unloading column 702 is connected to the cleaning mechanism 8, the harmful gases are collected, purified and discharged by the air pump to ensure that the environmental air indicators are within a safe range and the physical and mental health of the staff is guaranteed. The welding slag dust is collected in a centralized manner to reduce the subsequent cleaning of waste slag one by one and ensure the normal operation of welding. After the welding of the nut and the component is completed, the driving mechanism 6 is started to synchronously drive the feeding component 2 and the unloading component 7. The feeding component While component 2 pushes the prepared parts to be loaded, it drives the material storage linkage mechanism 3 to prepare for the next group of parts, and the material storage linkage mechanism 3 drives the storage mechanism 4 to feed the materials. The unloading component 7 rotates and unloads the parts that have been dry-welded, and moves to a new group of unloading columns 702 to the lower right side of the workbench 101 for the next group of parts processing. Thus, the processing is repeated continuously. The staff only needs to intermittently add automotive parts and nuts to the material storage linkage mechanism 3 and the storage mechanism 4, and there is no need to manually place the parts on the welding position repeatedly, thereby reducing contact with welding and improving the safety of the staff.
