Technical Field

[0001] This utility model relates to the field of metal material processing technology, and specifically to a positioning mechanism for an edge trimming and shaping device. Background Technology

[0002] The aluminum casting charger housing is the core protective component of the charger, primarily serving to prevent dust and water damage, provide electromagnetic shielding, dissipate heat, and provide structural support. Its molding process requires selection of techniques such as die casting, gravity casting, or squeeze casting, depending on the application scenario.

[0003] During the trimming and shaping process of aluminum casting charger housings, waste material left on the workbench after cutting can easily damage the workpiece. Workers are also prone to safety accidents when cleaning the workbench.

[0004] Therefore, it is desirable to provide a positioning mechanism for an edge trimming and shaping device in order to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning mechanism for a trimming and shaping device, which can automatically collect the waste generated after trimming and shaping of the workpiece.

[0006] To achieve the above-mentioned utility model objectives, this utility model provides a positioning mechanism for an edge trimming and shaping device, including a base plate and a worktable;

[0008] The workbench is fixed to the base plate; the workbench is provided with a contour plate, which is adapted to the workpiece to be trimmed and shaped.

[0009] A lower cutting blade is fixed around the contour plate on the worktable;

[0010] The workbench is provided with a slag discharge port on the outside of the lower cutter. The bottom of the slag discharge port is provided with a slag discharge slope. The lower end of the slag discharge slope has an outlet. The bottom plate is provided with a slag outlet directly below the outlet.

[0011] The slag discharge port is surrounded by a protective plate.

[0012] Preferably, the base plate is provided with a sliding groove along its length, and the worktable is slidably disposed on the sliding groove; the bottom of the worktable is provided with a set screw, which is used to fix the worktable after it slides to a suitable position.

[0013] Specifically, the lower surface of the contour plate is threaded with a contour plate limiting bolt, which slides through the bottom of the worktable;

[0014] Several contour plate limiting springs are provided between the contour plate and the worktable. One end of each contour plate limiting spring is connected to the contour plate, and the other end is connected to the worktable, and they are kept in a vertical position.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Example

[0026] like Figure 1As shown, the positioning mechanism for the edge trimming and shaping device provided in this embodiment includes a base plate 1 and a worktable 2; the base plate 1 is provided with guide posts 3 at the corners to guide the lifting device on the external hydraulic device; the worktable 2 is fixed on the base plate 1; the worktable 2 is provided with a contour plate 4, which is adapted to the workpiece to be trimmed and shaped; a lower cutting blade 5 is fixed around the contour plate on the worktable 2.

[0027] In this embodiment, the base plate 1 is provided with a slide groove 6 along its length direction, and the worktable 2 is slidably disposed on the slide groove 6; the bottom of the worktable 2 is provided with a set screw 7, which is fixed by the set screw 7 after the worktable 2 slides to a suitable position; this facilitates the adjustment of the position of the worktable 2, and cooperates with the pressing mechanism to perform edge trimming and shaping operations on the workpiece.

[0028] In this embodiment, the lower surface of the contour plate 4 is threaded with a contour plate limiting bolt 8, which slides through the bottom of the worktable 2. A plurality of contour plate limiting springs 9 are provided between the contour plate 4 and the worktable 2. One end of each contour plate limiting spring 9 is connected to the contour plate 4, and the other end is connected to the worktable 2, and they remain vertical. With this arrangement, when the upper pressing mechanism presses down to cut the edge, the contour plate 4 moves downward, which facilitates the cutting and shaping of the periphery of the workpiece. After the cutting is completed, the contour plate 4 returns to its original state upward under the elastic force of the contour plate limiting springs 9.

[0029] Furthermore, a plurality of first guide posts 10 are vertically fixed on the workbench 2, and the contour plate 4 is sleeved on the plurality of first guide posts 10; to ensure that the contour plate 4 will not deflect during the up and down movement.

[0030] In this embodiment, the workbench 2 is also provided with an air blowing device 11 located around the contour plate 4, which can blow away the residual debris on the workpiece after edge trimming and shaping.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, a slag discharge port 12 is provided on the workbench 2 outside the lower cutter. A slag discharge ramp 13 is provided at the bottom of the slag discharge port 12. An outlet 14 is provided at the lower end of the slag discharge ramp 13. A slag outlet 15 is provided on the bottom plate 1 directly below the outlet 14. A protective plate 16 is provided around the slag discharge port 12. In this vertical manner, when the upper pressing mechanism cooperates with the lower cutter to trim and shape the workpiece, the waste material passes through the slag discharge port 12, the slag discharge ramp 13, and finally falls from the slag outlet 15 into the external collection box for convenient centralized processing.

[0032] In this embodiment, as Figure 2As shown, at least two photoelectric sensors 31 are provided on one side of the worktable 2 at the edge of the contour plate 4, and a reflector 32 adapted to the photoelectric sensors 31 is provided on the other side of the worktable 2 at the edge of the contour plate 4. The reflector 32 corresponds one-to-one with the photoelectric sensor 31. With this arrangement, when the workpiece is placed flat, the reflector 32 can receive the light emitted by all the photoelectric sensors 31. However, if the light emitted by one photoelectric sensor is not received by the corresponding reflector, it indicates that the workpiece is not placed flat on the contour plate and needs to be repositioned to ensure the accuracy of subsequent edge trimming. In this embodiment, the number of photoelectric sensors 31 is two.

[0033] When trimming and shaping the workpiece, the workpiece is first placed on the contour plate 4, and the photoelectric sensor 31 detects whether the workpiece is placed flat. After it is placed flat, the pressing device starts to press down, and the upper cutter works with the lower cutter 5 to remove waste material around the workpiece. The removed waste material passes through the slag discharge port 12, the slag discharge slope 13, and finally falls from the slag outlet 15 into the external collection box for convenient centralized processing. After trimming, the piston rod of the cylinder 27 extends forward, so that the clamping plate 28 clamps the trimmed and shaped workpiece, and moves upward with the pressing mechanism. The external receiving device extends directly below the workpiece, the piston rod of the cylinder moves backward, and the workpiece falls into the receiving device.

[0034] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
