Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to an automatic leveling device. Background Art

[0002] Annular parts with high precision often require end surface flattening and rounding. Existing technologies often require separate processes for these processes, which is not only time-consuming and labor-intensive, but also requires multiple clamping operations that affect machining accuracy. In light of the above technical issues, this application proposes an automatic flattening device that can flatten the end surfaces of annular parts while also achieving rounding, saving time and effort and improving machining efficiency. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an automatic flattening device, aiming to solve the technical problem in the prior art that the end face flattening and rounding of annular parts cannot be processed simultaneously.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An automatic leveling device includes a top plate and a bottom plate, wherein a punching needle is provided on the top plate, a workbench is provided on the bottom plate, and a push trough, a workpiece placement position, and a discharge trough are provided on the workbench in sequence; a push rod is provided in the push trough, and a push cylinder is provided on the bottom plate, and the piston rod of the push cylinder is connected to the push rod; the punching needle includes an inner needle and an outer needle, and the bottom end of the outer needle is higher than the bottom end of the inner needle.

[0006] Furthermore, in the automatic leveling device, a material-blocking cylinder is provided on the bottom plate, and the piston rod of the material-blocking cylinder is connected to the material-blocking rod.

[0026] The present invention provides an automatic leveling device. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] See also Figures 1 to 6 The present invention provides an automatic leveling device. The accompanying drawings are only used to illustrate the structural principles and are not to scale with the actual product. The accompanying drawings only depict structures related to the invention of this application, and some conventional structures are not specifically depicted.

[0028] An automatic leveling device includes a top plate 11 and a bottom plate 12, wherein a punching needle 2 is provided on the top plate, a workbench 3 is provided on the bottom plate, a push trough 302, a workpiece placement position 300, and a discharge trough 304 are provided on the workbench in sequence; a push rod 51 is provided in the push trough, a push cylinder 5 is provided on the bottom plate, and the piston rod of the push cylinder is connected to the push rod; the punching needle includes an inner needle 21 and an outer needle 22, and the bottom end of the outer needle is higher than the bottom end of the inner needle.

[0029] For ease of understanding, Figure 2 Two annular workpieces are drawn, wherein 9' represents an annular workpiece that has not yet entered the workpiece placement position, and 9" represents an annular workpiece that has entered the workpiece placement position.

[0030] In practice, the top plate is connected to the punching slide of the punch press, while the bottom plate is mounted on the press bed. Because the structural principles of the punch press are already known, the accompanying drawings do not detail the punch press structure. Each punching operation not only flattens the end surface of the annular workpiece but also achieves a rounded inner circle.

[0031] Further, the base plate is provided with a stopper cylinder 6, the piston rod of which is connected to a stopper rod 61. The significance of setting the stopper rod is that it is convenient to ensure that the annular part is pushed to the workpiece placement position each time the material is pushed, and the annular part is not pushed out of the workpiece placement position due to excessive thrust.

[0032] like Figure 3 As shown, further, the workbench is provided with a stopper bar chute 303 at the corresponding stopper bar place. By arranging the stopper bar chute, the stopper bar is moved linearly in the stopper bar chute, thereby playing a good guiding role.

[0033] like Figure 5 and Figure 6As shown, a finger cylinder 6 is further positioned beneath the workbench. Two clamping fingers 61 extend upward from the workbench, each connected to a clamping block 62. Each clamping block has an arcuate groove 620 defined within it. The shape of these arcuate grooves matches the contour of the annular workpiece. During stamping, the finger cylinder clamps, ensuring that the arcuate grooves of the two clamping blocks adhere to the outside of the annular workpiece. This allows for simultaneous end face flattening, inner circle straightening, and outer circle straightening, further enhancing the utility of the automatic flattening device and the efficiency of annular workpiece processing.

[0034] Furthermore, the workbench is provided with a feeding chute 301, which is connected to the pushing chute. The significance of providing the feeding chute is that it facilitates cooperation with an automatic feeding device in practical applications, thereby further improving feeding efficiency. As a preferred embodiment, a corresponding vibrating plate loader (not shown) can be provided, with its outlet end connected to the feeding chute. Since the structural principle of the vibrating plate loader itself is prior art, it will not be explained in detail here.

[0035] Furthermore, the workbench is equipped with an air blowing device (not shown) located on the side opposite the discharge chute. In other words, the air blowing device is located on the same side as the push cylinder. After each annular part is processed, the air blowing device blows air into the annular part, pushing it into the discharge chute. This eliminates the need for manual removal of the annular part, improving work efficiency and operational safety. The attached figures do not illustrate the specific structure of the air blowing device; in practice, it will suffice as long as it can blow the completed annular part into the discharge chute.

[0036] Preferably, the discharge chute 304 is arranged to be inclined downward so that the ring star parts can fall smoothly after entering the discharge chute.

[0037] For ease of understanding, the working principle of the automatic leveling device is briefly described below.

[0038] (1) The ring parts to be processed are poured into the vibrating plate, and the vibrating plate sends the ring parts to the loading chute one by one.

[0039] (2) After the annular part leaves the loading chute, it is pushed to the workpiece placement position by the push cylinder. During the pushing process, the finger cylinder is released, and the stop cylinder drives the stop rod to extend to play the role of stopping the material; after the loading is completed, the stop cylinder drives the stop rod to retract.

[0040] (3) Stamping: the inner needle is inserted into the inner hole of the annular part, and the bottom end of the outer needle is against the upper end surface of the annular part; at the same time, the finger cylinder is clamped so that the arc grooves of the two clamping blocks are clamped on the outside of the annular workpiece.

[0041] (4) After the stamping is completed, the inner needle is withdrawn from the inner hole of the annular part, and the finger cylinder drives the two clamping blocks to loosen; the blowing device blows air to the processed annular part and blows it into the discharge trough.

[0042] From the above analysis, it can be seen that during each stamping process, the upper and lower end faces of the annular part are pressed by the vertical force, so that the two end faces are flattened (because the lower end face of the annular part and the workpiece are placed in opposition, the lower end face will also be flattened); because the inner needle is inserted into the inner hole of the annular part, it plays the role of straightening the inner circle; and the finger cylinder drives the clamping block to clamp the annular part, so it also plays the role of straightening the outer circle.

[0043] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the present invention.
