Description

Technical Field

[0001] This utility model relates to a loading device for rough workpieces. Background Technology

[0002] In motorcycle parts manufacturing, when producing crankcase center sleeves, multiple crankcase center sleeve blanks are simultaneously loaded into a vibratory feeder. The feeder then vibrates the blanks for subsequent processing. The current method involves loading multiple crankcase center sleeve blanks produced in the previous process into a storage bin. Once the bin is full, the entire bin of blanks is manually poured into the vibratory feeder. However, due to the weight of the crankcase center sleeve blanks, this method typically requires male workers, causing difficulties in processing arrangements and increasing the workload for the workers. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a loading device for rough workpieces, which can conveniently place the crankcase center sleeve blank on the vibratory plate for subsequent processing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a loading device for rough blanks, comprising:

[0005] Material frame, used to store crankcase center sleeve blanks;

[0006] The support frame is positioned close to the vibratory feeder.

[0007] The rotating frame includes a connecting frame and a support plate. The top of the rotating frame is hinged to the support frame and located on the side away from the vibratory feeder. The support plate is located at the bottom of the connecting frame and is used to support the material frame.

[0008] A rotary drive source, mounted on a support frame and connected to a connecting frame, drives the connecting frame to rotate. When the connecting frame rotates more than 90°, the material outlet of the material frame is located directly above the vibratory feeder.

[0009] A blocking structure is installed on the connecting frame. During the rotation of the connecting frame, the blocking structure can prevent the material frame from falling off the support plate.

[0010] Furthermore, it also includes an intermittent conveying mechanism for forward conveying the material frame containing the crankcase center sleeve blank; the support plate is located at the discharge end of the intermittent conveying mechanism. When the rotating frame hangs down naturally, the top of the intermittent conveying mechanism and the support plate are set at the same height and close to each other. The material frame conveyed from the intermittent conveying mechanism can be automatically pushed onto the support plate by subsequent material frames.

[0011] Furthermore, the rotary drive source includes a telescopic mechanism and a strut, the strut being positioned at the top of the connecting frame, the telescopic mechanism being hinged to the bottom end of the support frame, and the telescopic shaft of the telescopic mechanism being hinged to the strut.

[0012] Furthermore, the blocking structure includes a baffle rod, which is disposed at the top of the connecting frame and extends laterally outward.

[0013] Furthermore, there are two material stop bars, which are spaced apart.

[0014] Furthermore, the blocking structure also includes a lifting drive source, on which both baffles are mounted. The lifting drive source can drive the two baffles to rise and fall vertically relative to the support plate.

[0015] Furthermore, the lifting drive source includes a lifting mechanism and a connecting rod. The lifting mechanism is mounted on the support plate, the connecting rod is mounted on the lifting shaft of the lifting mechanism, and two stop rods are mounted on the connecting rod for driving the connecting rod to lift perpendicular to the support plate.

[0016] The beneficial effects of this utility model are:

[0017] When using the above-mentioned loading device for rough blanks, the material frame filled with the crankcase center sleeve blank can be placed on the support plate first, and then the material frame can be moved horizontally onto the support plate. Then, the blocking structure blocks the top of the material frame. When it is necessary to pour the blank into the vibratory feeder, the rotation drive source is started, and the connecting frame is rotated more than 90°. The discharge port of the material frame is located directly above the vibratory feeder. At this time, the blank in the material frame is poured into the vibratory feeder. Since the blocking structure blocks the material frame at this time, the material frame can be prevented from falling.

[0018] Using the above-mentioned loading device, crankcase housing center sleeve blanks can be easily, quickly, and in batches placed into the vibratory feeder, facilitating the processing of the next step. Attached Figure Description

Detailed Implementation

[0024] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0025] Please see Figures 1 to 2 This utility model provides a loading device for rough workpieces, including a material frame 100, a support frame 200, a rotating frame 300, a rotation drive source 400, and a blocking structure 500.

[0026] Specifically, the material frame 100 is used to store the crankcase center sleeve blank. The support frame 200 is located near the vibratory feeder. The rotating frame 300 includes a connecting frame 310 and a support plate 320. The top of the rotating frame 300 is hinged to the support frame 200 and located on the side away from the vibratory feeder. The support plate 320 is located at the bottom of the connecting frame 310. The support plate 320 is used to support the material frame 100. The rotation drive source 400 is located on the support frame 200 and connected to the connecting frame 310, used to drive the connecting frame 310 to rotate. When the connecting frame 310 rotates to its highest point, the outlet of the material frame 100 is located directly above the vibratory feeder. The blocking structure 500 is located on the connecting frame 310. During the rotation of the connecting frame 310, the blocking structure 500 can prevent the material frame 100 from falling off the support plate 320.

[0027] In use, the material frame 100 filled with the blank in the center of the crankcase can be placed on the support plate 320. Then, the material frame 100 is moved horizontally onto the support plate 320 and blocked at the top of the material frame 100 by the blocking structure 500. When the blank needs to be poured into the vibratory feeder, the rotary drive source 400 is started. After the drive connecting frame 310 rotates more than 90°, the discharge port of the material frame 100 is located directly above the vibratory feeder. At this time, the blank in the material frame 100 is poured into the vibratory feeder. Since the blocking structure 500 blocks the material frame 100 at this time, the material frame 100 can be prevented from falling.

[0028] Using the above-mentioned loading device, crankcase housing center sleeve blanks can be easily, quickly, and in batches placed into the vibratory feeder, facilitating the processing of the next step.

[0029] In this embodiment, the rotary drive source 400 includes a telescopic mechanism 410 and a support rod 420. The support rod 420 is disposed on the top of the connecting frame 310, the telescopic mechanism 410 is hinged to the bottom end of the support frame 200, and the telescopic shaft of the telescopic mechanism 410 is hinged to the support rod 420.

[0030] When the telescopic shaft of the telescopic mechanism 410 extends, it pushes the support rod 420, thereby driving the connecting frame 310 to rotate, which can drive the material frame 100 to rotate upward. However, when the telescopic shaft of the telescopic mechanism 410 retracts, it can drive the material frame 100 to rotate downward.

[0031] In this embodiment, the blocking structure 500 includes a baffle rod 510, which is disposed at the top of the connecting frame 310 and extends laterally outward. When the material frame 100 is at its top and material is being poured, the baffle rod 510 prevents the material frame 100 from falling. As a preferred embodiment, in specific implementation, at least two baffle rods 510 can be provided, with the two baffle rods 510 blocking the material frame 100 on the left and right sides to further improve the material blocking effect.

[0032] As a more preferred embodiment, the blocking structure 500 also includes a lifting drive source 520, and both baffle rods 510 are mounted on the lifting drive source 520. The lifting drive source 520 can drive the two baffle rods 510 to rise and fall vertically with respect to the support plate 320.

[0033] By driving the baffle rod 510 to rise and fall by the lifting drive source 520, it can adapt to different material frames 100 heights. At the same time, the baffle rod 510 can be pressed tightly against the top of the material frame 100 to improve the blocking effect.

[0034] Specifically, the lifting drive source 520 includes a lifting mechanism 521 and a connecting rod 522. The lifting mechanism 521 is mounted on the support plate 320. The connecting rod 522 is mounted on the lifting shaft of the lifting mechanism 521. Two stop rods 510 are mounted on the connecting rod 522 and are used to drive the connecting rod 522 to lift perpendicularly to the support plate 320. In practical implementation, the height of the stop rods 510 can be adjusted according to the height of the material frame 100 so that the stop rods 510 are pressed against the top of the material frame 100.

[0035] In another embodiment, the device may also include an intermittent conveying mechanism 600, which is used to forward convey the material frame 100 containing the crankcase center sleeve blank. Specifically, the support plate 320 is located at the discharge end of the intermittent conveying mechanism 600. When the rotating frame 300 hangs down naturally, the top of the intermittent conveying mechanism 600 and the support plate 320 are at the same height and close to each other. The material frame 100 conveyed from the intermittent conveying mechanism 600 can be automatically pushed onto the support plate 320 by subsequent material frames 100.

[0036] In practice, after the previous process is completed, the blank is placed in the material frame 100, and then multiple material frames 100 are placed sequentially on the intermittent conveying mechanism 600. During the feeding process, the material frames 100 are conveyed to the support plate 320 through the gaps in the conveying mechanism.

[0037] The method of using the above-mentioned loading device for rough blanks:

[0038] After the previous process is completed, the blank is placed in the material frame 100, and then multiple material frames 100 are placed sequentially on the intermittent conveying mechanism 600. During the feeding process, the material frames 100 are conveyed to the support plate 320 through the gaps of the conveying mechanism.

[0039] When the material frame 100 is conveyed to the support plate 320, the telescopic mechanism 410 is activated, driving the material frame 100 to rotate upward. After the material frame 100 finishes unloading, the telescopic shaft of the telescopic mechanism 410 retracts, driving the material frame 100 back to its original position. Then, after the empty material frame 100 is manually removed, the subsequent material frames 100 of the intermittent conveying mechanism 600 are pushed onto the support plate 320, and the next feeding can be carried out.

[0040] Using the above-mentioned loading device for rough blanks, crankcase housing center sleeve blanks can be easily, quickly, and in batches placed in the vibratory feeder, facilitating the next processing step and reducing the labor intensity of workers.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
