Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment, and specifically relates to a limiting mechanism applied to the operating box of a CNC machine tool. Background Technology

[0002] The control box of a CNC machine tool is an important human-machine interface component that needs to be opened and closed frequently for debugging, maintenance and other tasks.

[0003] Existing traditional control box limit mechanisms are designed so that after the control box rotates to a certain angle, a pad at the bottom impacts a pad on the control box mounting base, thus physically blocking movement. This leads to the following problems:

[0004] 1. The impact is significant when opening and closing, affecting the overall lifespan of the gaskets and housing.

[0005] 2. The gasket is welded to the bottom of the control box and the control box mounting base. The process is complex and the labor cost is high. If the gasket is damaged in the future, it is inconvenient to replace it.

[0006] 3. The existing limit mechanism uses a fixed stop whose limit angle is set at the factory and cannot be changed, resulting in poor versatility. Utility Model Content

[0007] Purpose of the utility model: In order to overcome the shortcomings of the prior art, this utility model provides a limiting mechanism for the operation box of CNC machine tools. It has a simple structure, low cost, strong adjustability, high reliability, and can accurately control the limiting angle, so as to improve its adaptability and user experience.

[0008] Technical solution: A limiting mechanism for a CNC machine tool operating box, comprising: a fixed base, a limiting block, a limiting screw, a washer, a mounting washer, a rubber ring, a connecting bolt, a copper washer, an anti-loosening washer, a lock nut, an operating box body, an upper cable routing port, and an upper fixing plate of the operating box;

[0009] The fixed seat is installed on the outer protection of the machine tool, and the protruding end face of the fixed seat is connected to the connecting bolt by screws; the limiting block is connected to the fixed seat by screws, the limiting screw passes through the mounting washer and is connected to the operating box, the mounting washer is connected to the operating box by screws, the mounting washer coincides with the end face of the rubber ring, and the rubber ring is installed at the bottom of the connecting bolt.

[0010] The copper washer and the mounting washer have their end faces coincide, the anti-loosening washer and the copper washer have their end faces coincide, and the locking nut and the anti-loosening washer have their end faces coincide.

[0011] The upper cable routing port is installed on the top of the operating box with screws. The upper fixing plate of the operating box is installed on the outer protection of the machine tool. The upper cable routing port is inserted into the notch of the upper fixing plate of the operating box.

[0012] When the operating box rotates, the mounting shim rotates around the connecting bolt, and the limiting screw rotates with the mounting shim. When it rotates to a set angle, the blocked part of the limiting screw will contact the limiting block, and the movement will be stopped, thereby achieving the limiting.

[0013] As an optimization, a washer is provided between the limiting screw and the mounting washer.

[0014] As an optimization, the upper cable routing port is coaxial with the upper fixing plate of the control box.

[0015] As an optimization: while the operating box rotates, the upper cable routing port rotates within the notch of the fixing plate on the operating box.

[0016] Beneficial effects: The specific advantages of this utility model are as follows:

[0017] 1. The limiting mechanism of this utility model is highly adjustable. The limiting angle of the operating box can be changed by adjusting the position of the limiting block, so different rotation angles can be achieved to adapt to various scenarios and customer needs.

[0018] 2. The limiting mechanism of this utility model has a simple structure and low cost. The core components are connecting bolts and screws, which are easy to purchase and process. No welding or grinding is required, and the production efficiency is high.

[0019] 3. The mounting gaskets of the limiting mechanism of this utility model are equipped with leather rings and copper gaskets on both sides, which increases the service life.

[0020] The operator or maintenance personnel of the limiting mechanism of this utility model can quickly determine whether the connection is reliable by visually inspecting whether the screws are in place and tightened; if small parts such as screws are damaged, only the screws need to be replaced or the threaded holes need to be repaired. The replacement cost of the limiting mechanism of this utility model is extremely low and the operation is simple, requiring no professional tools or skills. Attached Figure Description

[0027] Example

[0028] like Figure 1-6 As shown, a limiting mechanism for a CNC machine tool operating box includes: a fixed base 1, a limiting block 2, a limiting screw 3, a washer 4, a mounting shim 5, a rubber ring 6, a connecting bolt 7, a copper washer 8, an anti-loosening washer 9, a locking nut 10, an operating box body 11, an upper cable routing port 12, and an upper fixing plate 13 for the operating box.

[0029] The fixed base 1 is installed on the outer protection of the machine tool. The protruding end face of the fixed base 1 is connected to the connecting bolt 7 by screws. The limiting block 2 is connected to the fixed base 1 by screws. The limiting screw 3 passes through the mounting washer 5 and is connected to the operating box 11. A washer 4 is provided between the limiting screw 3 and the mounting washer 5. The mounting washer 5 is connected to the operating box 11 by screws. The end face of the mounting washer 5 coincides with that of the rubber ring 6. The rubber ring 6 is installed at the bottom of the connecting bolt 7. The end face of the copper washer 8 coincides with that of the mounting washer 5. The end face of the anti-loosening washer 9 coincides with that of the copper washer 8. The locking nut 10 coincides with that of the anti-loosening washer 9.

[0030] The upper cable routing port 12 is installed on the top of the operating box 11 by screws. The upper fixing plate 13 of the operating box is installed on the outer protection of the machine tool. The upper cable routing port 12 is inserted into the notch of the upper fixing plate 13 of the operating box. The upper cable routing port 12 and the upper fixing plate 13 of the operating box are coaxial.

[0031] When the operator rotates the control box 11, the mounting shim 5 rotates around the connecting bolt 7, and the limit screw 3 rotates with the mounting shim 5. When it reaches the set angle, the blocked part of the limit screw 3 will contact the limit block 2, and the movement will be stopped, thereby achieving the limit. Figure 3 and Figure 4 To determine the specific limit positions when the limit screw is at two extremes, the upper cable routing port 12 rotates within the notch of the upper fixing plate 13 of the operating box while the operating box 11 rotates.

[0032] The limiting mechanism of this utility model is highly adjustable. The limiting angle of the operating box can be changed by adjusting the position of the limiting block, so different rotation angles can be achieved to adapt to various scenarios and customer needs. The structure is simple and the cost is low. The core components are connecting bolts and screws, which are easy to purchase and process. No welding or grinding is required, and the production efficiency is high. The mounting gaskets are equipped with leather rings and copper gaskets on both sides, which increases the service life.

[0033] The operator or maintenance personnel of this utility model can quickly determine whether the connection is reliable by visually inspecting whether the screws are in place and tightened. If small parts such as screws are damaged, only the screws need to be replaced or the threaded holes need to be repaired. The replacement cost of this utility model's limit mechanism is extremely low and the operation is simple, requiring no professional tools or skills.

[0034] The foregoing description clearly and completely illustrates the technical solutions in the embodiments of this utility model, enabling those skilled in the art to better understand the advantages and features of this utility model, thereby providing a clearer definition of the scope of protection of this utility model. The embodiments described in this utility model are merely some embodiments of this utility model, not all embodiments.
