Description

Technical Field

[0001] The utility model relates to the field of a self-enclosed oil cylinder clamp device for a numerically controlled gantry drilling and milling machine, and more specifically to a self-enclosed oil cylinder clamp device for a numerically controlled gantry drilling and milling machine. Background Art

[0002] Gantry milling machine is short for gantry milling machine. It is a milling machine with a gantry frame and a long horizontal bed. Multiple milling cutters can be used to process surfaces at the same time on the gantry milling machine. The processing accuracy and production efficiency are relatively high. It is suitable for processing the plane and inclined surface of large workpieces in batch and mass production. CNC gantry milling machine can also process space curved surfaces and some special parts.

[0003] However, it is not convenient to position the parts when processing large parts. The center positioning of the fixture is inaccurate and the clamping is unreliable, which leads to errors in the processing of parts and even scrapping. In addition, the centering and clamping devices used in current CNC gantry drilling and milling machines are extremely inconvenient to clean up the debris generated by processing and discharge the cutting fluid. The long-term accumulation of debris and cutting fluid will rust and block the internal centering and clamping mechanisms, causing damage to the parts and even failure of the overall function of the mechanism, so improvements are needed.

[0004] In the prior art, such as the authorized CN215616664U, a self-enclosed cylinder clamp device for a CNC gantry drilling and milling machine includes a workbench for placing materials and four movable supports that move on the workbench, and the four movable supports are all fixed with cylinder seats, and the cylinder seats are fixed with cylinders. The utility model coordinates the four movable supports, the cylinders, and the cylinder seats in different positions, and adjusts and controls according to the size of the parts to be processed. It is suitable for parts of different sizes and shapes, and firmly fixes the processed parts to avoid shaking of the parts, ensures the processing quality, and avoids the scrapping of the workpiece, damage to the tool or even the machine tool due to the displacement of the workpiece position during the processing. At the same time, the chips and cutting fluid generated by the processing will not enter the cylinder clamping mechanism, causing the cylinder to rust and block, causing the clamping mechanism to fail;

[0005] In the above patent, the position clamping can be adjusted when clamping parts, but it can only meet the requirements of squeezing and clamping the workpiece from the upper end to the lower end. Some workpieces are large in size and high in height. The above patent cannot meet the clamping conditions and the clamping is not flexible. Utility Model Content

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] The cam is connected with the Y-shaped hinged seat on the inner surface of the cam, and the cam is connected with the Y-shaped hinged seat on the inner surface of the cam.

[0009] Furthermore, a threaded hole is provided on the surface of the slider, and the second bolt is connected to the inner surface of the threaded hole of the slider through a thread, and the second bolt is squeezed and fixed to the inner surface of the convex slide groove of the base, which is convenient for the installation of the second bolt.

When clamped from top to bottom, the bolt is inserted into the first positioning hole to position the angle seat. After the angle seat is turned over, the bolt can be inserted into the second positioning hole for positioning, which makes positioning convenient.

[0011] Furthermore, the outer surface of one side of the extrusion block is fitted to the inner surface of the angle seat, and the fitting and sliding are stable.
