Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, specifically to a CNC machining device for mold manufacturing. Background Technology

[0002] CNC machining equipment, also known as numerical control machine tools, is a flexible and high-efficiency automated machine tool. It can send various control signals to control the machine tool's movements and automatically process parts according to the shape and size required by the drawings. This effectively solves the problem of processing complex, precise, small-batch, and multi-variety parts, and is especially suitable for mold manufacturing.

[0003] Currently, to facilitate real-time observation of the tool's machining status by operators, existing machine tool protective doors provide observation conditions by nesting a transparent plate. However, during machining, the coolant output from the machine tool will splash onto the inner wall of the transparent plate due to changes in the tool's movement position, thus obstructing the operator's field of vision. On the other hand, turning off the coolant output will cause the tool to heat up, accelerate wear, and be detrimental to the sustainable use of the tool and affect the overall machining effect. Therefore, in summary, existing CNC machining tools still need further improvement. Utility Model Content

[0024] A meshing transmission device is provided at the bottom of the rear end of the curved support plate 6.

[0027] Working principle:

[0028] Example 1

[0029] During the milling process of the Z-axis milling mechanism 3 on the blank mounted on the top of the tooling 4, the two protective doors 5 come into contact and close the clearance space at the front end of the CNC machine tool body 1. At the same time, the camera body 71 inside the composite camera 7 is opened by the processor body 83 and the image captured by the camera body 71 is displayed in real time on the display screen 82. Subsequently, the operator can understand the milling situation of the Z-axis milling mechanism 3 on the top blank of the 4 in real time through the display screen 82.

[0030] When it is necessary to change the viewing angle of different positions, the brake servo motor 12 is started by the processor body 83. The output end of the brake servo motor 12 drives the first gear 10 to rotate synchronously. Then, the first gear 10 meshes with the second gear 11, and the second gear 11 drives the composite camera 7 to rotate around the circumference of the auxiliary support rod through the auxiliary support rod, so that the curved transparent sleeve 72 can shoot from different angles.

[0031] Example 2

[0032] When dirt adheres to the outer surface of the curved transparent sleeve 72 during prolonged use of the composite camera 7, the processor body 83 activates the brake servo motor 12. The output of the brake servo motor 12 drives the first gear 10 to rotate synchronously. Then, the first gear 10 meshes with the second gear 11, which in turn drives the composite camera 7 to rotate around the circumference of the auxiliary support rod. This causes the curved transparent sleeve 72 to reciprocate in contact with the rubber scraper 132 inside the scraper assembly 13. The rubber scraper 132 automatically cleans the dirt adhering to the surface of the curved transparent sleeve 72, thereby maintaining the effective shooting effect of the camera body 71 for a long time.
