Description

Technical Field

[0001] The invention relates to the field of production and processing of automobile parts, in particular to a multi-station feeding device for forging a limiter bracket. Background Art

[0002] The stopper bracket is typically mounted on the stopper and bolted to the vehicle body, securing the stopper. As one of the most numerous parts in a car, the stopper bracket is in high demand, requiring high processing efficiency.

[0003] To improve the efficiency of forging stopper brackets, manufacturers often use equipment that can forge stopper bracket workpieces at multiple stations at once. To ensure the smooth implementation of this processing plan, the workpieces must be loaded one by one onto different stations, but traditional loading equipment cannot currently solve this technical problem. Summary of the Invention

[0004] In order to overcome the above-mentioned defect that it is difficult to perform multi-station loading on the limiter bracket, the present invention proposes a multi-station loading device for forging the limiter bracket.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0006] The multi-station loading system for forging stopper brackets features a main processing table with several processing slots arranged in a circular pattern. The table also houses a main cover frame, on which are mounted a chute barrel and a feed position variable drive mechanism. The feed position variable drive mechanism is connected to a spindle, which is then connected to a material unloading control assembly. A limit plate is welded to the right end of the spindle, to which a feeder bar is welded. The processing slots serve as the final loading location and processing station. The main processing table's surface accommodates fixtures and processing equipment for processing the stopper brackets. The chute barrel, which extends vertically, stores the stopper brackets. The feed position variable drive mechanism controls the rotation of the feeder bar, allowing the workpiece to be fed to different processing slots. The unloading control assembly controls the release of the workpiece from the feeder bar after each transport. The feeder bar transports the workpiece, while the limit plate forms the final transport stop. The internal cross-sectional shape of the trough barrel corresponds to the shape of the limiter bracket.

[0007] As a further improvement to the present invention, the feed position drive mechanism comprises an A-type motor mounted on the main housing frame, a main dial connected to the A-type motor, a driven sheave adapted to the main dial, a lower shaft connected to the driven sheave, and a traverse frame mounted at the lower end of the lower shaft. The main shaft is mounted on the traverse frame via a bearing block. The sheave mechanism allows for intermittent rotation of the traverse frame and the main shaft, with the intermittent period facilitating each feed. The lower shaft is positioned at the center of the circular path formed by all the machining slots 1a.

[0008] As a further improvement of the present invention, the lower shaft is rotatably mounted on the main cover frame, a plurality of slots are evenly distributed on the driven sheave, and a pin is provided on the main dial to match the slots.

[0009] As a further improvement of the present invention, the angle between the main shaft rod and the feeding square rod and the horizontal plane is set to 30 degrees. That is, the feeding square rod is lower on the left and higher on the right and is tilted, so that the workpiece can be loaded on the feeding square rod and transported from right to left under the action of gravity.

[0010] As a further improvement to the present invention, the unloading control assembly comprises a B-type motor mounted on the indexing frame, an A-type gear connected to the B-type motor, and a B-type gear meshing with the A-type gear; the B-type gear is mounted on the spindle. When the workpiece slides leftward and abuts the stop plate, the B-type motor 12, driven by the gears, rotates the spindle and feed rod 90 degrees, allowing the workpiece to be released.

[0011] As a further improvement to the present invention, two auxiliary limit plates are welded to the limit plate, and the feeder rod is located in the area between the upper and lower auxiliary limit plates; an auxiliary limit rod is welded to either of the two auxiliary limit plates. The right end of the auxiliary limit rod is flush with the right end of the feeder rod. The two auxiliary limit plates are used to ensure that the workpiece does not deviate when it falls off the feeder rod. The right part of the auxiliary limit rod is used to ensure that the workpiece always abuts against the rear end of the workpiece when it slides on the feeder rod for transportation, preventing the workpiece from sliding off from the rear side.

[0012] As a further improvement to the present invention, a U-shaped temporary storage rack is welded to the bottom of the chute drum; the bottom of the U-shaped temporary storage rack forms a 30-degree angle with the horizontal plane. During feeding, the workpieces in the chute drum first fall onto the U-shaped temporary storage rack, then slide to the left under the action of gravity until they are mounted on the feeding rod and continue sliding.

[0013] As a further improvement of the present invention, a three-axis cylinder is also installed on the main cover frame, and the three-axis cylinder is connected to a blocking block that can slide on the U-shaped temporary storage frame. Under normal circumstances, the blocking block blocks the lower end of the material chute, and will be driven to the right by the three-axis cylinder when material is needed.

[0014] As a further improvement to the present invention, a conveyor channel is provided above each processing slot, and all conveyor channels are connected to a collection frame fixedly mounted on the main processing table. Workpieces that have escaped from the feeding square rod will move steadily downward through the corresponding conveyor channel to the corresponding processing slot for loading.

[0015] As a further improvement of the present invention, two extension plates are provided at the upper end of each conveying channel, which further ensure that the falling workpiece will not deviate and fall stably into the conveying channel.

[0016] As a further improvement of the present invention, the number of the intermediate slots is consistent with the number of the processing slots.

[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention adopts multiple limit functions to ensure that the limiter bracket can be stably transported to each work station, with good reliability.

[0019] 2. The present invention can automatically load and transport workpieces to different workstations, with convenient control, high transportation efficiency, and convenience for subsequent clamping and processing.

[0020] 3. The technical solution proposed by the present invention is that the main transport part can be realized by relying on the action of gravity, which not only simplifies the control but also saves energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be explained more clearly and completely below in conjunction with the drawings in the embodiments. Of course, the described embodiments are only a part of the present invention, not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0032] like Figures 1 to 4 As shown, the multi-station loading device for forging a stopper bracket comprises a main processing table 1 with several processing slots 1a arranged in a circular pattern. The main processing table 1 also houses a main cover frame 2, on which are mounted a feed trough barrel 3 and a feed position variable drive mechanism. The feed position variable drive mechanism is connected to a spindle 4, which is connected to a discharge control assembly. A limit plate 5 is welded to the right end of the spindle 4, to which a feed square rod 6 is welded. The processing slot 1a represents the final loading location and processing station. The tabletop of the main processing table 1 accommodates fixtures and processing equipment for processing the stopper bracket. The feed trough barrel 3 extends vertically and is used to store the stopper bracket. The feed position variable drive mechanism controls the rotation of the feed square rod 6, thereby feeding the workpiece to different processing slots 1a. The discharge control assembly controls the release of the workpiece from the feed square rod 6 after each transport. The feeding square rod 6 is used to convey the workpiece, and the limit plate 5 is the end of the workpiece conveying. The internal cross-sectional shape of the trough barrel 3 corresponds to the shape of the limiter bracket.

[0033] like Figure 1 and Figure 5As shown, the feed position variable drive device consists of an A-type motor 7 mounted on the main cover frame 2, a main dial 8 connected to the A-type motor 7, a driven sheave 9 adapted to the main dial 8, a lower shaft 10 connected to the driven sheave 9, and a traverse frame 11 mounted on the lower end of the lower shaft 10. The main shaft 4 is mounted on the traverse frame 11 via a bearing seat. The sheave mechanism allows the traverse frame 11 and the main shaft 4 to rotate intermittently, with the intermittent period facilitating each feeding operation. The lower shaft 10 is located at the center of the circular trajectory formed by all the processing slots 1a.

[0034] like Figure 5 As shown, the lower shaft 10 is rotatably mounted on the main cover frame 2, a plurality of slots 9a are evenly distributed on the driven sheave 9, and a pin 8a adapted to the slots 9a is provided on the main dial 8. The above structure is a conventional design of a sheave.

[0035] like Figure 1 As shown, the angle between the main shaft rod 4 and the feeding square rod 6 and the horizontal plane is set to 30 degrees. That is, the feeding square rod 6 is lower on the left and higher on the right and is tilted, so that the workpiece can be carried on the feeding square rod 6 and transported from right to left under the action of gravity.

[0036] like Figure 1 and Figure 4 As shown, the unloading control assembly consists of a B-type motor 12 mounted on the indexing frame 11, an A-type gear 13 connected to the B-type motor 12, and a B-type gear 14 meshing with the A-type gear 13. The B-type gear 14 is mounted on the spindle 4. When the workpiece slides leftward and abuts the stop plate 5, the B-type motor 12 drives the gear transmission, causing the spindle 4 and the feed square rod 6 to rotate 90 degrees, allowing the workpiece to be released.

[0037] like Figure 6 As shown, two auxiliary limiting plates 15 are welded to the limiting plate 5, and the feeder rod 6 is located in the area between the two auxiliary limiting plates 15. An auxiliary limiting rod 16 is welded to each of the two auxiliary limiting plates 15. The right end of the auxiliary limiting rod 16 is flush with the right end of the feeder rod 6. The two auxiliary limiting plates 15 are used to ensure that the workpiece does not deviate when it falls off the feeder rod 6. The right part of the auxiliary limiting rod 16 ensures that the workpiece always abuts against the rear end of the workpiece when it slides on the feeder rod 6 for transportation, preventing it from sliding off the rear side.

[0038] like Figure 1 and Figure 7 As shown, a U-shaped temporary storage rack 17 is welded to the bottom of the chute 3; the bottom of the U-shaped temporary storage rack 17 is at an angle of 30 degrees to the horizontal plane. During feeding, the workpieces in the chute 3 will first fall onto the U-shaped temporary storage rack 17, then slide to the left under the action of gravity until they are carried by the feeding rod 6 and continue to slide.

[0039] like Figure 1 and Figure 2 As shown, a three-axis cylinder 18 is also installed on the main cover frame 2, and the three-axis cylinder 18 is connected to a blocking block 19 that can slide on the U-shaped temporary storage frame 17. Under normal circumstances, the blocking block 19 blocks the lower end of the material chute barrel 3, and when material is needed, it will be driven to the right by the three-axis cylinder 18.

[0040] like Figure 1 and Figure 4 As shown, a conveyor channel 20 is provided above each processing slot 1a, and all conveyor channels 20 are connected to a collection frame 21 fixedly mounted on the main processing table 1. The workpiece separated from the feeding square rod 6 will move steadily downward through the corresponding conveyor channel 20 to the corresponding processing slot 1a for loading.

[0041] like Figure 4 As shown, two extension plates 20 a are provided at the upper end of each conveying channel 20 , which further ensure that the falling workpieces will not deviate and fall stably into the conveying channel 20 .

[0042] It should be noted that the number of the intermediate slots 9a is consistent with the number of the processing slots 1a, and the numbers in the figure are only for reference.

[0043] Before use, just Figure 8 The limiter bracket shown is vertically stacked in the chute tube 3 with the multiple holes facing right.

[0044] During use, the following two steps can be performed during each rest phase.

[0045] In the first step, the three-axis cylinder 18 can pull the blocking block 19 to the right, allowing a workpiece to fall onto the U-shaped temporary storage rack 17 first, then move to the left and be carried on the feeding square rod 6 to slide against the limit plate 5, and then the three-axis cylinder 18 pushes the blocking block 19 to the left to continue blocking.

[0046] The A-type motor 7 is driven to rotate, driving the indexing frame 11 and the feeding square rod 6 to rotate intermittently around the lower shaft 10.

[0047] In the second step, the A-type gear 13 can be driven to rotate and the feeding square rod 6 can be rotated 90 degrees, so that the porous surface of the workpiece faces right and then faces downward, thereby automatically falling and stably entering the corresponding processing slot 1a through the conveying channel 20, completing one loading of the workpiece, and then the feeding square rod 6 is rotated and reset.

[0048] When the indexing frame 11 and the feeding square rod 6 complete a full revolution, the workpiece can be loaded into all workstations.

[0049] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and description merely illustrate the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention.
