Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for engraving machines, specifically to an automatic fixture removal upper cover plate mechanism for engraving machines. Background Technology

[0002] A CNC engraving and milling machine is a high-precision, high-efficiency CNC machining equipment capable of performing various machining operations such as engraving, milling, drilling, and cutting. It combines the advantages of engraving machines and machining centers, and is suitable for precision cutting, engraving, and drilling of various materials. As a highly efficient and precise CNC machining device, it is widely used in industries such as electronics, mold making, aerospace, and medical devices. Its high precision, versatility, and high efficiency make it an indispensable tool in modern manufacturing.

[0003] Currently, the main components of a conventional CNC engraving machine on the market are the engraving spindle, fixture platform, base, and tilting axis, plus auxiliary mechanisms such as tool magazine and waste collection. When in use, workers need to manually lift the top cover and change products. Changing products requires stopping the machine, which is not very automated and the time for workers to change products is long, affecting the machine's production capacity. At the same time, the operation is somewhat dangerous. Using a robotic arm to remove the top cover would increase costs and also increase the complexity of the robotic arm's operation and the handling of parts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic fixture removal mechanism for a precision engraving machine, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic fixture upper cover plate removal mechanism for a precision engraving machine, comprising a mounting plate, a fixing block provided on the surface of the mounting plate, a fixing connector provided on the surface of the fixing block, a clamping jaw fixing block connected to the bottom of the fixing connector by bolts, a clamping jaw block provided at the bottom of the clamping jaw fixing block, an upper cover plate snapped onto the clamping jaw block, and a fixture upper cover plate provided at the bottom of the upper cover plate snap.

[0006] Optionally, the mounting plate may also include a mounting bracket on its surface, a cylinder mounting plate on one side of the mounting bracket, a lifting cylinder on its surface, a gripper connecting plate on the drive end of the lifting cylinder, and elongated horizontal holes for Y-axis fine adjustment on the surface of the mounting bracket.

[0007] Optionally, the gripper fixing block is mounted on the gripper connecting plate.

[0008] Optionally, the surface of the fixed connector is also provided with the elongated horizontal hole for fine adjustment in the Y direction.

[0009] Optionally, the surface of the gripper block is provided with a fixing groove, the size of which is adapted to the size of the upper cover plate buckle.

[0010] Optionally, the surface of the gripper fixing block is provided with a connecting elongated hole for X-axis fine adjustment.

[0011] This utility model provides an automatic fixture removal and upper cover plate mechanism for a precision engraving machine, which has the following beneficial effects:

[0012] 1. The automatic fixture removal cover plate mechanism of this engraving machine can be directly installed on the engraving spindle of the engraving machine. When the engraving spindle descends to engrave, the mechanism descends simultaneously to cover the engraved product. When the engraving is completed, the cover plate is lifted as the engraving spindle rises, making it convenient for operators to change products. This allows for product changes without stopping the machine, greatly improving the working efficiency of the engraving machine. At the same time, it avoids the risks associated with operators lifting the cover, further enhancing automation.

[0013] 2. This engraving machine features an automatic fixture top cover plate lifting mechanism. For engraving machines that do not employ lifting and lowering mechanisms, this mechanism with a lifting cylinder can be used to automatically lift and lower the fixture top cover plate. This makes the mechanism suitable for various engraving machines. By installing it on the engraving machine itself, it can effectively reduce the complexity of the robot arm's operation and the number of parts to be picked up and placed. It helps to simplify the weight of the robot arm's loading fixture, enabling lightweight robot arm loading and unloading, thereby increasing the robot arm's cycle speed, optimizing time, and improving productivity.
