Description

Technical Field

[0001] The invention belongs to the technical field of tooling fixtures, in particular to a welding fixture for a wheel cover of an automobile. Background Art

[0002] Automobile wheel covers, also commonly known as hub covers or wheel locks, are a circle of plastic or metal protective covers installed above the four wheels of a motor vehicle. The wheel covers can block dirt, stones and other debris thrown up during driving, preventing these debris from causing scratches or impact damage to the wheels. During the production process of automobile wheel covers, it is necessary to weld the various components of the wheel covers, and in order to ensure the stability of the wheel covers during the welding process, the wheel covers need to be fixed with a clamp.

[0003] The patent with announcement number CN217618724U discloses a welding fixture for automobile wheel cover, which belongs to the technical field of tooling fixtures. It mainly aims at the problem that the existing device cannot clamp wheel covers of different diameters, and proposes the following technical solutions: including a bottom plate, a side plate, a mounting shaft, an annular clamping seat, a limiting ring, a motor, a threaded rod and a pressure block; two side plates are provided, both of which are arranged on the bottom plate, and the two side plates are distributed in the transverse direction; two mounting shafts are provided, and the two mounting shafts are respectively rotatably arranged on the inner sides of the two side plates; the annular clamping seat is arranged between the two mounting shafts, and an opening is arranged on the side of the annular clamping seat; the limiting ring is arranged at the bottom of the annular clamping seat, and a side opening is arranged on the side of the limiting ring, and the side opening is located directly below the opening; the motor is arranged on the side plate, and the motor is connected to the mounting shaft by driving. This patent can clamp wheel covers of different thicknesses and diameters.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] Although wheel covers of different thicknesses and diameters can be clamped, workers still need to remove the welded wheel covers before the subsequent wheel covers can be clamped. In most cases, the welding process of automobile wheel covers is performed by a robotic arm with a welding gun, and workers do not need to hold the welding gun to weld. When multiple wheel covers are welded in sequence, workers are required to frequently remove the welded wheel covers and clamp the subsequent wheel covers. This requires workers to be near the fixture and be ready to replace the wheel covers at any time. When the welding cycle is long, it will delay workers from doing other work and affect work efficiency. In addition, in some cases, the welded wheel covers need to be transferred to the next process. After the workers remove the welded wheel covers, the wheel covers may be placed in a relatively messy state on the periphery, thereby affecting the subsequent transportation efficiency. It is also more laborious for workers to manually organize the wheel covers.

[0006] To this end, the present invention provides a welding fixture for a wheel cover of an automobile. Summary of the invention

[0048] Specifically, the existing automobile wheel cover welding fixture can clamp wheel covers of different thicknesses and diameters during use, but the welded wheel cover still needs to be removed by workers before the subsequent wheel cover can be clamped. In most cases, the welding process of automobile wheel cover is performed by a robot arm with a welding gun, and workers do not need to hold the welding gun for welding. When welding multiple wheel covers in sequence, workers need to frequently remove the welded wheel cover and clamp the subsequent wheel cover, which requires workers to be near the fixture and be ready to replace the wheel cover at any time. When the welding cycle is long, it will delay the workers from doing other work, affecting the work efficiency. In addition, in some cases, the welded wheel cover needs to be transported to the next process. After the workers remove the welded wheel cover, the wheel cover may be placed in a relatively messy state around, thereby affecting the subsequent transportation efficiency. It is also more laborious for workers to manually organize the wheel cover.

[0049] Therefore, in order to solve the above problems, this embodiment is used for the same batch of wheel covers with the same specifications; multiple wheel covers to be welded are placed in multiple placement grooves 4 in sequence, and the turntable 3 is driven to rotate by the motor 5 35, so that the multiple wheel covers on the turntable 3 move simultaneously, and when the turntable 3 rotates, the bottom of the rotating ring 16 is away from the upper end surface of the turntable 3. When the axis of the placement groove 4 where the wheel cover is placed coincides with the axis of the rotating ring 16, the motor 2 12 drives the threaded rod 1 13 to rotate, so that the lifting plate 14 can be lowered. At this time, the clamping block The wheel cover is fixed by a pair of clamping blocks 21. When the wheel cover is welded, the lifting plate 14 rises again, and the turntable 3 rotates again to remove the welded wheel cover. The next wheel cover is moved between the clamping blocks 21. The above operation is repeated to weld the wheel covers in the plurality of placement grooves 4 in sequence. Moreover, the worker can carry out other work after placing the plurality of wheel covers in the placement grooves 4 at one time, which saves the worker from frequently removing the welded wheel cover and clamping the subsequent wheel cover, and does not delay the worker from carrying out other work, thereby improving the worker's work efficiency.

[0050] When the welding of a wheel cover is completed, the lifting plate 14 is driven to rise. At the same time, the motor 10 drives the lifting plate 14 to rotate 180 degrees so that the wheel cover is above the tray 36, and then the wheel cover is driven to descend. When the tray 36 contacts the wheel cover, the clamp block 21 loosens the wheel cover. At this time, the wheel cover is placed on the tray 36, and then the lifting plate 14 is reset. After the wheel cover is placed on the tray 36, the motor 8 24 drives the gear 2 47 to rotate, so that the rack rod 49 and the tray 36 move downward by the same distance as the wheel cover height. Repeat the above operation, and multiple wheel covers can be stacked together by placing the upper end of the previous wheel cover on the subsequent wheel cover. When the stacked wheel covers need to be collected, the tray 36 is driven to descend to a position where its upper end surface is flush with the upper end surface of the displacement plate 37, and then the motor 7 46 drives the threaded rod 3 45 to rotate The plurality of adjusting rods 48 are moved radially to move the adjusting ring 244 downward, so that the plurality of connecting rods 243 are rotated at the same time, and the plurality of adjusting rods 248 are driven to move radially at the same time, so that the clamping plate 42 is close to the wheel cover until the plurality of stacked wheel covers are fixed. Moreover, even if the wheel cover is offset with the movement of the tray 36, it can be kept neat under the action of the plurality of clamping plates 42. Then, the electric push rod 38 is used to drive the displacement plate 37 to move so that it is removed from the bottom of the wheel cover, and the collection container is placed under the displacement plate 37. At this time, the clamping plate 42 is driven to loosen the wheel cover, and the wheel cover will fall into the collection container. Then, the workers can transport the collected wheel covers, and the wheel covers in the collection container are neatly stacked, thereby avoiding the problem of low transportation efficiency due to the disorderly placement of the plurality of wheel covers. At the same time, it also saves the workers from the need to manually organize the wheel covers, which is more convenient and labor-saving.

[0051] Furthermore, it can be known from the above content that when the wheel covers need to be collected, all the wheel covers will fall into the collection container at one time. However, in some cases, multiple wheel covers may need to be transferred to different processes for processing in batches to meet different processing requirements. When all the wheel covers fall into the collection container at one time, it will be difficult to process them in batches. Therefore, in order to solve this problem, after all the wheel covers are clamped by the clamping plate 42, according to the number of wheel covers that need to be collected at one time, the motors 6 41 on both sides are used to drive the threaded rods 5 53 on both sides to rotate, so that the connecting block 54 moves up and down, so that the clamping block 2 51 is aligned with the wheel covers at different heights, and then the electric push rod 4 50 is used to drive The second clamping block 51 contacts the wheel cover, and the wheel cover can be fixed under the action of the two second clamping blocks 51. When the clamping plate 42 releases the wheel cover, the wheel cover in the area below the second clamping block 51 will fall into the collection container, while the wheel cover above the second clamping block 51 will stay in place. When the wheel covers in the area below the second clamping block 51 are all placed in the collection container, the tray 36 is driven again to support the remaining wheel covers, and the second clamping block 51 releases the wheel covers. Repeating the above operation can realize multiple batch operations, thereby avoiding the situation that all wheel covers fall into the collection container at one time, which makes it difficult to transport the wheel covers in batches to different processes, and is convenient to meet different processing requirements.

[0052] In most cases, for the sake of heat dissipation performance, aesthetics, and ease of processing and manufacturing, a plurality of holes are evenly arranged in the radial direction on the wheel cover. In the processing procedure after the wheel cover is welded, in some cases, in order to facilitate the assembly of the stacked wheel covers, it is necessary to align the holes of the stacked wheel covers, which is conducive to uniform assembly. However, when the workers place the wheel covers in the placement groove 4, it is not easy to control the angle of the wheel covers, resulting in inconsistent angles of the wheel covers placed in the placement groove 4, which will cause the holes of the stacked wheel covers to be in a non-aligned state. This will affect the efficiency of unified assembly of the wheel cover. Therefore, in order to solve this problem, after the wheel cover is welded, according to the distance between the wheel cover hole and its center, the motor 28 is used to drive the threaded rod 29 to rotate, so that the threaded block 31 moves horizontally until the pressure sensor 33 is lowered and can pass through the hole of the wheel cover. Then, the electric push rod 17 is used to drive the mounting plate 27 to descend. When the end of the pressure sensor 33 is flush with the upper end surface of the wheel cover, if the pressure sensor 33 contacts the solid part of the wheel cover, the pressure sensor 33 detects a pressure signal, and the motor 36 is turned on. The gear 1 25 is driven to rotate, and the rotating ring 16 can be rotated. When the pressure sensor 1 33 cannot detect the pressure signal, it means that the pressure sensor 1 33 is aligned with the hole area of ​​the wheel cover. At this time, the mounting plate 27 will drop again, so that the pressure sensor 1 33 extends into the hole of the wheel cover, and then the wheel cover continues to rotate. When the pressure sensor 2 34 detects the pressure signal, it means that one side of the hole of the wheel cover is in contact with the pressure sensor 2 34, and the wheel cover stops rotating. Then the pressure sensor 1 33 is driven to extend out of the hole of the wheel cover, and then the wheel cover is transferred to the tray 36. If the pressure sensor 1 33 drops to a position flush with the upper end of the wheel cover and no pressure is detected, it means that the pressure sensor 1 33 has been aligned with the hole, then the pressure sensor 1 33 continues to drop and extend into the hole, and the wheel cover rotates until the pressure sensor 2 34 can detect a signal. Repeat the above operation. As long as one side of the wheel cover hole contacts the pressure sensor 2 34, the wheel cover stops rotating and is transferred to the tray 36, which can ensure that all stacked wheel cover holes are aligned, which is conducive to the unified assembly of multiple wheel covers, thereby improving the assembly efficiency.

[0053] Working principle: the wheel cover to be welded is placed in the placement groove 4 on the turntable 3, and the turntable 3 is driven to rotate by the motor 5 35, so that the multiple wheel covers on the turntable 3 are moved at the same time, and when the turntable 3 rotates, the bottom of the rotating ring 16 is away from the upper end surface of the turntable 3. When the axis of the placement groove 4 where the wheel cover is placed coincides with the axis of the rotating ring 16, the motor 2 12 drives the threaded rod 13 to rotate, so that the lifting plate 14 can be lowered. At this time, the electric push rod 23 is used to drive the adjustment ring 15 to move upward, so that multiple connecting rods 19 can be rotated at the same time, and the connecting rod 19 drives multiple adjustment rods 20 to move radially at the same time and approach the wheel cover. When multiple clamping blocks 21 are all in contact with the wheel cover, the wheel cover is fixed, and the wheel cover can be welded, thereby ensuring The stability of the wheel cover during the welding process is ensured. When the wheel cover welding is completed, the lifting plate 14 rises again, and the turntable 3 rotates again to remove the welded wheel cover, and the next wheel cover is moved between multiple clamping blocks 21. The above operation is repeated to weld the wheel covers in multiple placement grooves 4 in sequence. Moreover, the worker can carry out other work after placing multiple wheel covers in the placement grooves 4 at one time, which saves the worker from frequently removing the welded wheel cover and clamping the subsequent wheel cover, and does not delay the worker from carrying out other work, thereby improving the worker's work efficiency. When the welding of a wheel cover is completed, the lifting plate 14 is driven to rise. At the same time, the motor 10 drives the lifting plate 14 to rotate 180 degrees, so that the wheel cover is above the tray 36, and then the lifting plate 14 is driven to rotate 180 degrees. The wheel cover descends, and when the tray 36 contacts the wheel cover, the clamp block 21 releases the wheel cover. At this time, the wheel cover is placed on the tray 36, and then the lifting plate 14 is reset. After the wheel cover is placed on the tray 36, the motor 8 24 drives the gear 2 47 to rotate, so that the rack rod 49 and the tray 36 move downward by the same distance as the wheel cover height. Repeat the above operation, and multiple wheel covers can be stacked together by placing the upper end of the previous wheel cover on the subsequent wheel cover. When the stacked wheel covers need to be collected, the tray 36 is driven to descend to a position where its upper end surface is flush with the upper end surface of the displacement plate 37, and then the motor 7 46 is used to drive the threaded rod 3 45 to rotate, so that the adjusting ring 2 44 moves downward, so that multiple connecting rods 2 43 can be rotated at the same time, and bring The plurality of adjusting rods 2 48 are moved radially at the same time to make the clamping plates 42 approach the wheel covers until the plurality of stacked wheel covers are fixed. Furthermore, even if the wheel covers are offset as the tray 36 moves, they can be kept neatly arranged under the action of the plurality of clamping plates 42. Then, the electric push rod 38 is used to drive the displacement plate 37 to move it away from the bottom of the wheel covers, and the collection container is placed under the displacement plate 37. At this time, the clamping plates 42 are driven to loosen the wheel covers, and the wheel covers will fall into the collection container. The workers can then transfer the collected wheel covers, and the wheel covers in the collection container are neatly stacked, thereby avoiding the problem of low transfer efficiency caused by the disorderly placement of the plurality of wheel covers. At the same time, the workers do not need to manually arrange the wheel covers, which is more convenient and labor-saving.Furthermore, it can be known from the above content that when the wheel covers need to be collected, all the wheel covers will fall into the collection container at one time. However, in some cases, multiple wheel covers may need to be transferred to different processes for processing in batches to meet different processing requirements. When all the wheel covers fall into the collection container at one time, it will be difficult to process them in batches. Therefore, in order to solve this problem, after all the wheel covers are clamped by the clamping plate 42, according to the number of wheel covers that need to be collected at one time, the motors 6 41 on both sides are used to drive the threaded rods 5 53 on both sides to rotate, so that the connecting block 54 moves up and down, so that the clamping block 2 51 is aligned with the wheel covers at different heights, and then the electric push rod 4 50 is used to drive The second clamping block 51 contacts the wheel cover, and the wheel cover can be fixed under the action of the two second clamping blocks 51. When the clamping plate 42 releases the wheel cover, the wheel cover in the area below the second clamping block 51 will fall into the collection container, while the wheel cover above the second clamping block 51 will stay in place. When the wheel covers in the area below the second clamping block 51 are all placed in the collection container, the tray 36 is driven again to support the remaining wheel covers, and the second clamping block 51 releases the wheel covers. Repeating the above operation can realize multiple batch operations, thereby avoiding the situation that all wheel covers fall into the collection container at one time, which makes it difficult to transport the wheel covers in batches to different processes, and is convenient to meet different processing requirements.In most cases, for the sake of heat dissipation performance, aesthetics, and ease of processing and manufacturing, a plurality of holes are evenly arranged in the radial direction on the wheel cover. In the processing procedure after the wheel cover is welded, in some cases, in order to facilitate the assembly of the stacked wheel covers, it is necessary to align the holes of the stacked wheel covers, which is conducive to uniform assembly. However, when the workers place the wheel covers in the placement groove 4, it is not easy to control the angle of the wheel covers, resulting in inconsistent angles of the wheel covers placed in the placement groove 4, which will cause the holes of the stacked wheel covers to be in a non-aligned state. This will affect the efficiency of unified assembly of the wheel cover. Therefore, in order to solve this problem, after the wheel cover is welded, according to the distance between the wheel cover hole and its center, the motor 28 is used to drive the threaded rod 29 to rotate, so that the threaded block 31 moves horizontally until the pressure sensor 33 is lowered and can pass through the hole of the wheel cover. Then, the electric push rod 17 is used to drive the mounting plate 27 to descend. When the end of the pressure sensor 33 is flush with the upper end surface of the wheel cover, if the pressure sensor 33 contacts the solid part of the wheel cover, the pressure sensor 33 detects a pressure signal, and the motor 36 is turned on. The gear 1 25 is driven to rotate, and the rotating ring 16 can be rotated. When the pressure sensor 1 33 cannot detect the pressure signal, it means that the pressure sensor 1 33 is aligned with the hole area of ​​the wheel cover. At this time, the mounting plate 27 will drop again, so that the pressure sensor 1 33 extends into the hole of the wheel cover, and then the wheel cover continues to rotate. When the pressure sensor 2 34 detects the pressure signal, it means that one side of the hole of the wheel cover is in contact with the pressure sensor 2 34, and the wheel cover stops rotating. Then the pressure sensor 1 33 is driven to extend out of the hole of the wheel cover, and then the wheel cover is transferred to the tray 36. If the pressure sensor 1 33 drops to a position flush with the upper end of the wheel cover and no pressure is detected, it means that the pressure sensor 1 33 has been aligned with the hole, then the pressure sensor 1 33 continues to drop and extend into the hole, and the wheel cover rotates until the pressure sensor 2 34 can detect a signal, and the above operation is repeated. As long as one side of the wheel cover hole contacts the pressure sensor 2 34, the wheel cover stops rotating and is transferred to the tray 36, which can ensure that the holes of all stacked wheel covers are aligned, which is conducive to the unified assembly of multiple wheel covers, thereby improving the assembly efficiency. ;
