Description

Technical Field

[0001] The utility model relates to the field of arc gate processing, in particular to an arc gate panel processing device. Background Art

[0002] The radial gate has a small opening and closing force and good hydraulic conditions. It is widely used in various types of waterways as a working gate. In order to ensure the matching accuracy of the radial gate and the gate groove corner water stop, it is usually necessary to mill the curved panel to ensure the accuracy of the center of the circle to the panel processing surface. At present, there are many solutions for the milling of the curved panel of the radial gate: such as fixing the milling machine bed horizontally in a special pit, and the arc gate rotates around the axis of the horizontal hinge axis, which requires a large amount of civil engineering; or fixing the milling machine bed vertically. The vertical fixation of the milling machine bed usually requires a matching arc slide, arc gate push-pull mechanism, hinged foundation and leaf gate diagonal brace, which has a complex structure and occupies a large area; or using CNC milling and boring machines for processing, but there is often a problem that the CNC milling and boring machine has a limited processing range due to the large size of the arc gate. Therefore, how to simplify the processing of radial gates is crucial to this industry. Summary of the invention

[0003] In view of this, the utility model proposes a radial gate panel processing device, which only needs to preserve the door leaf of the radial gate during the processing, thereby simplifying the processing of the panel.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The arc gate panel processing device described in the utility model includes a bed and a water seal milling mechanism slidably arranged on the bed, and also includes a pulling mechanism and a positioning structure connected to the pulling mechanism, the positioning structure is attached to the arc panel of the arc gate, the bed is fixed on the positioning structure, and the positioning structure makes the cutter head surface of the water seal milling mechanism perpendicular to the normal line passing through the center of the arc panel; the positioning structure includes a positioning frame with a lower left side and a higher right side, and the bottom of the positioning frame is an arc structure that matches the arc surface of the arc panel. The beneficial effect is: the utility model installs the bed on the positioning frame and uses the pulling mechanism for traction, which not only realizes the fixation of the water seal milling mechanism, but also reduces the processing difficulty and processing cost of the arc panel, and can also ensure that the center of the cutter head surface of the water seal milling mechanism is perpendicular to the normal line passing through the center of the arc panel, thereby ensuring the processing accuracy.

[0006] Preferably, the positioning structure further comprises a lower adjustment screw arranged on the bottom plate of the positioning frame and an upper adjustment screw arranged on the top plate of the positioning frame, and the lower adjustment screw is a pointed structure. The beneficial effect is that the upper adjustment screw and the lower adjustment screw of the utility model can be used to fine-tune the position of the bed, thereby aligning the cutter disc, ensuring the positioning accuracy of the cutter disc, and thus ensuring the processing accuracy.

[0007] Preferably, the pulling mechanism is a hand chain hoist, and the pulling mechanism and the positioning structure are multiple and one-to-one corresponding, and the multiple positioning structures are arranged at intervals along the length direction of the bed. The beneficial effect is that the positioning structure of the utility model is multiple, so that the bed is subjected to balanced force and the processing reliability is effectively guaranteed.

[0008] Compared with the prior art, the utility model installs the bed on a positioning frame and uses a pulling mechanism for traction. It has a simple structure and not only realizes the fixation of the water seal milling mechanism, but also reduces the processing difficulty and cost of the arc panel. It can also ensure that the center of the cutter head surface of the water seal milling mechanism is perpendicular to the normal line through the center of the arc panel, thereby ensuring the processing accuracy.

[0014] It should be noted that, in the description of the present utility model, relational terms such as "first" and "second" are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0015] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connection" that may appear should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0016] like Figure 1-3As shown, the arc gate panel processing device described in the utility model includes a bed 1, a water seal milling mechanism 2 slidably arranged on the bed 1, a pulling mechanism 3 and a positioning structure 4 connected to the pulling mechanism 3, the pulling mechanism 3 is preferably a hand chain hoist, and the positioning structure 4 is pulled by the hand chain hoist; there are multiple positioning structures 4 and they are arranged at intervals along the length direction of the vehicle body to effectively ensure the fixing stability; each positioning structure 4 is attached to the arc panel 6 of the arc gate 5, the bed 1 is fixed on the positioning structure 4, and the positioning structure 4 makes the cutter head surface of the water seal milling mechanism 2 perpendicular to the normal line F3 passing through the center of the arc panel 6; the positioning structure 4 includes a positioning frame 4.1 (the whole is a triangular structure) with a lower left and a higher right, and the bottom of the positioning frame 4.1 is an arc structure matched with the arc surface of the arc panel 6, which effectively ensures that the positioning frame 4.1 is attached to the arc panel 6 of the arc gate 5.
