[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0018] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.
[0019] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.
[0020] Combination Figure 1-6 As shown, the four-station processing device includes a machine table 1, on which a rotatable rotating disk 2 is provided, and the rotating disk 2 is evenly provided with four pairs of clamping components along the circumferential direction, and the machine table 1 is provided with a guide mechanism 3 and a punching mechanism 4 in a counterclockwise direction toward the rotating disk, and the punching mechanism 4 includes a stand 41, and a press frame 42 is provided on the top of the stand 41, and a guide opening is opened in the press frame 42, and a T-shaped lifting plate 43 is provided in the guide opening, and the bottom of the lifting plate 43 is connected to a punching plate 44, and the bottom of the punching plate 44 is opened A pair of punching holes 45, slots 46 are provided on both sides of the press frame 42, short columns 47 are provided in the slots 46, and the short columns 47 pass through the lifting plate 43, and springs 48 are provided on the short columns 47 and at the bottom of the lifting plate 43, a punching cylinder 49 is provided at the tail of the stand 41, a driving plate 410 is provided on the driving shaft of the punching cylinder 49, the end of the driving plate 410 passes through the press frame 42 and is located on the top surface of the lifting plate 43, and a guide edge 411 inclined upward and inward is formed at the bottom of the driving plate 410.
[0021] After the crankshaft is processed, some of the crankshafts will have burrs on their end faces, and such crankshafts cannot be directly sold out of the factory. The staff will select the crankshafts and classify them. If there are only a few burrs on the end faces of the crankshafts, they can be deburred using this device so that they can be sold again.
[0022] In the embodiment, the machine is reversely arranged in sequence with a loading station, a guide station, a punching station, and a blanking station, wherein a pair of clamping components are arranged on the rotating disk corresponding to the above four stations, and the guide station and the punching station are respectively a guide mechanism and a punching mechanism, and the above loading station and the blanking station can be respectively a loading hand clamp and a blanking hand clamp. The above loading hand clamp and the blanking hand clamp are not the key contents of the present device, so they will not be described here.
[0023] When processing the crankshaft, first the current clamping assembly rotates to the loading station, and the loading station loads the crankshaft onto the current clamping assembly. At this time, the crankshaft is placed vertically and the top of the crankshaft is the processing end. The rotating disk rotates one station in the opposite direction, and the current clamping assembly rotates to the guiding station, and the guiding mechanism guides the crankshaft. At the same time, the loading station continues to load the crankshaft to be processed to the next clamping assembly, and then the rotating disk rotates one station again, and the current clamping assembly rotates to the stamping station. After the stamping mechanism stamps the crankshaft, the rotating disk continues to rotate one station, and the current clamping assembly rotates to the unloading station for unloading. The device is used to perform guiding and stamping on the end of the crankshaft in one go to remove the internal and external burrs on the end of the crankshaft, making the end of the crankshaft smoother, further improving the quality of the crankshaft, and the entire device can continuously deburr the end of the crankshaft with high efficiency.
[0024] Combination Figure 1 The clamping assembly includes a pair of rotating cylinders 5 fixed on a rotating disk 2, and the driving shaft of each rotating cylinder 5 is connected to a pneumatic chuck 6. In this clamping assembly, the number of the pneumatic chucks is 2, and the clamping assembly can clamp two crankshafts at one time through the pneumatic chucks, which can improve the processing effect. The pneumatic chuck can be rotated by the rotating cylinder.
[0025] When stamping the crankshaft, the front clamping assembly rotates to the stamping station, and the stamping cylinder drives the driving plate to move inward. During the movement, the guide edge at the bottom of the driving plate gradually presses the lifting plate downward, and the stamping plate moves toward the crankshaft until the top ends of the two crankshafts are respectively inserted into the corresponding stamping ports, and the stamping of the crankshaft is completed.
[0026] The upper end of the crankshaft is punched by a punching mechanism to further remove the burrs in the end of the crankshaft, making the crankshaft smoother and improving the quality of the crankshaft. The spring of the punching plate is gradually compressed during the punching process. When the punching is completed, the driving plate is reset under the action of the punching cylinder. At this time, the spring recovers its deformation, and the lifting plate is reset under the action of the spring.
[0027] In this structure, the lifting plate is a T-shaped structure and the two wings at the upper end of the lifting plate are both located in the notch on the same side, and the notch serves to limit the lifting plate. It is also convenient to install short columns, which make the lifting plate more stable during the lifting process, so that the stamping effect on the crankshaft is better.
[0028] like Figure 4The top surface of the lifting plate 43 is provided with a guide notch 7. By providing the guide notch, when the stamping cylinder drives the driving plate to move, the guide notch can guide and limit the guide edge at the bottom of the driving plate, making the process of the driving plate pressing the lifting plate more stable, further improving the stamping effect.
[0029] As a preferred structure, Figure 6 The guide mechanism 3 includes a fixed frame 31, a slide 32 is provided on the top surface of the fixed frame 31 facing inward, a guide seat 33 is provided on the slide 32, a pair of grinding blocks 34 are provided on the guide seat 33, and a guide cylinder 35 for driving the slide 32 to move is also provided on the fixed frame 31. The guide seat 33 is vertically slidably mounted on the slide 32, a locking block 36 is provided on the top of the slide 32, an adjusting stud 37 is screwed into the locking block 36, and the bottom of the adjusting stud 37 passes through the locking block 36 and is connected to the guide seat 33.
[0030] When the clamping assembly rotates to the edge guiding station, the edge guiding mechanism guides the clamped pair of crankshafts. During the edge guiding process, the edge guiding cylinder first drives the slide to slide toward the rotating disk until the two grinding blocks contact the top of the crankshaft respectively. Then, the rotating cylinder drives the pneumatic chuck to rotate at least one circle. During the rotation of the pneumatic chuck, the grinding block guides the crankshaft to remove the burrs on the outer side of the crankshaft end.
[0031] In this structure, the height of the guide seat can be fine-tuned to adapt to crankshafts of different heights. When the installation position of the guide seat needs to be fine-tuned, such as when the installation position of the guide seat needs to be raised, the adjusting stud can be turned counterclockwise, and the adjusting screw moves upward, thereby driving the guide seat to move upward along the side wall of the slide seat until it is adjusted to the right position.
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
