Description

Technical Field

[0001] The invention relates to the technical field of case cover processing, in particular to laser processing equipment and a method for processing a case cover of a motorcycle engine. Background Art

[0002] The motorcycle engine case cover is an important part of the motorcycle engine. It has the functions of protecting the internal parts of the engine, sealing the engine, dissipating heat and providing structural support. During the processing, the motorcycle engine case cover needs to be punched at its edge for bolt connection so that the motorcycle engine case cover can be stably installed on the engine. In order to improve the punching efficiency, laser punching is generally used when punching the engine case cover. Although the working efficiency of laser punching is relatively high, it has certain shortcomings, namely, high-energy lasers will cause the material to melt and evaporate, and there may be burnt carbonized residues on the formed hole walls, which require staff to clean up later. This cleaning process is troublesome because the residue is in the hole. Not only is the cleaning efficiency relatively low, but it also makes the staff's work intensity relatively high, which is very inconvenient. Summary of the invention

[0027] A method for processing a motorcycle engine case cover comprises the following steps:

[0028] Step 1: Pushing the workpiece: Position the workpiece on the workpiece carrier, and use the pneumatic push rod to drive the workpiece carrier to move, so that the workpiece moves to the working point;

[0029] Step 2: Punching the workpiece: After the workpiece is moved to the working point, the laser puncher is started to punch holes in it;

After the workpiece drilling is completed, the workpiece carrier moves in the opposite direction and the matching driving platform will push the bearing movable plate to move, which can drive the supporting movable plate to move so that the supporting movable plate is above the hole, which is convenient for cleaning the residue in the hole.

[0034] 3. In addition, during the drilling process of the workpiece, the supporting movable plate is not above the hole, which makes it convenient for the laser puncher to perform drilling operations on the workpiece and avoids interference of the supporting movable plate on the drilling. After the drilling is completed, when the supporting movable plate moves to the top of the hole, as the workpiece bearing table resets, the supporting movable plate will be driven downward by the lower driving inclined plate, so that the slag pushing column is inserted into the hole, and the residue in the hole can be pushed out from the lower port of the hole to achieve cleaning without manual operation.

[0055] like Fig. 9As shown, a mating plug-in rod 63 is fixedly provided at the lower end of the supporting movable plate 6, and the mating plug-in rod 63 is plugged into the mating through hole 56. A third connecting spring 64 is sleeved on the mating plug-in rod 63, and a movable carrier 65 is fixedly provided at the lower end of the mating plug-in rod 63. A slag pushing column 66 is fixedly provided on the lower side of the movable carrier 65. The two ends of the third connecting spring 64 are respectively fixed on the supporting movable plate 6 and the bearing mounting block 55. In addition, the diameter of the slag pushing column 66 is equal to the drilling diameter.

[0056] A method for processing a motorcycle engine case cover comprises the following steps:

[0057] Step 1: Pushing the workpiece: Position the workpiece on the workpiece carrier 2, and use the pneumatic push rod 12 to drive the workpiece carrier 2 to move, so that the workpiece moves to the working point;

[0058] Step 2: punching a hole in the workpiece: after the workpiece is moved to the working point, the laser puncher 11 is started to punch a hole in the workpiece;

[0059] Step 3: Removal of the workpiece: After the workpiece is drilled, the workpiece carrier 2 drives the workpiece to move in the reverse direction to reset it. During the reverse movement, the slag pushing column 66 is inserted into the hole to push the residue in the hole out, and the workpiece can be removed.

[0060] When punching the engine case cover, it is positioned and placed on the workpiece carrier 2, and then the pneumatic push rod 12 drives the workpiece carrier 2 to move in the direction of the laser puncher 11, so that the engine case cover moves to the working point, and the laser puncher 11 performs the punching operation. When the workpiece carrier 2 moves in the direction of the laser puncher 11, the mating drive platform 3 is at the lower side of the first protrusion 51 at this time. When the first protrusion 51 passes over the driving inclined surface 35, as the workpiece carrier 2 continues to move, the push-up mating plate 25 will contact the driving connecting plate 38, so that under the action of the push-up mating plate 25, the driving connecting plate 38 will be pushed to move in the direction away from the supporting carrier 16, and then under the action of the movable connecting rod 37, The mating driving platform 3 is pushed to move upward so that the mating driving platform 3 is on one side of the first protrusion 51. In addition, as the workpiece bearing platform 2 moves, the supporting convex plate 24 will be separated from the mating contact plate 41, so that the supporting convex plate 24 will no longer limit the mating contact plate 41. As the mating driving platform 3 moves upward, when the mating bearing hole 34 is aligned with the supporting limit rod 4, the supporting limit rod 4 will be driven to move under the action of the first connecting spring 43, and then the supporting limit rod 4 will be inserted into the mating bearing hole 34. The mating driving platform 3 is supported by the supporting limit rod 4 to be in a stable state. When the drilling is completed, the pneumatic push rod 12 drives the workpiece bearing platform 2 to move in the reverse direction. During the upward movement, the first matching wheel 52 on the first protrusion 51 will contact the driving inclined surface 35, so that under the action of the driving inclined surface 35, the supporting movable plate 5 will be pushed to move in the direction of the workpiece supporting platform 2 until the first matching wheel 52 passes over the driving inclined surface 35. As the supporting movable plate 5 moves, it will also drive the supporting movable plate 6 to move above the hole. At this time, the second protrusion 61 is below the lower driving inclined plate 15. As the workpiece supporting platform 2 continues to move, the second matching wheel 62 will contact the lower driving inclined plate 15. Under the action of the lower driving inclined plate 15, the second matching wheel 62 will be pushed to move downward, thereby driving the supporting movable plate 6 to move downward. As the supporting movable plate 6 moves downward, it will also drive the movable carrier 6 The frame 65 moves downward, so that the slag pushing column 66 on the movable carrier 65 is inserted into the hole on the engine case cover. In this way, the residue in the hole can be pushed out from the lower port of the hole under the action of the slag pushing column 66, so that the residue is cleaned without the need for staff to clean it. When the second matching wheel 62 passes over the lower drive inclined plate 15, the supporting movable plate 6 will be pushed upward under the action of the third connecting spring 64, so that the slag pushing column 66 withdraws from the hole on the engine case cover. At the same time, the first matching wheel 52 is separated from the matching driving platform 3. In this way, the supporting movable plate 5 is reset under the action of the second connecting spring 54, and as the workpiece bearing platform 2 continues to reset and move, the supporting convex plate 24 will contact the matching contact plate 41 again.In this way, under the action of the supporting convex plate 24, the matching contact plate 41 will be driven to move in the direction of the mounting bearing plate 191, so that the supporting limit rod 4 will withdraw from the matching bearing hole 34 and no longer support the matching driving platform 3. In this way, the matching driving platform 3 will move downward and reset under the action of its own gravity. As the matching driving platform 3 moves downward and resets, the driving connecting plate 38 will also be driven to reset under the action of the movable connecting rod 37, so that the matching driving platform 3 moves down to the lower side of the first convex bracket 51 again, which will not affect the movement of the workpiece bearing platform 2 in the direction of the laser puncher 11. In addition, during the drilling process, the supporting movable plate 6 of the engine cover is not above the drilling position, avoiding its obstruction to the drilling.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
