Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of precision manufacturing, in particular to a column precise positioning mechanism based on inclined plane locking. Background Art
[0002] As one of the core components of CNC milling and boring machines, the accuracy of its installation position is directly related to the overall machining accuracy and performance of the machine tool. The column is usually fixed to the slide by bolts, but since the machine tool spindle will generate strong cutting forces when working, these forces will generate component forces in the X and Z directions. If these component forces are sufficient to overcome the friction between the column and the slide, it will lead to a tendency of relative displacement between the two, which will seriously affect the machining accuracy and stability of the machine tool.
[0003] In order to solve this problem, a reliable locking mechanism must be installed between the column and the slide. The traditional locking method usually uses a locating pin. Although this method can fix the position of the column to a certain extent, it has some obvious disadvantages in practical applications. First, the installation of the locating pin needs to be done manually after the column is accurately adjusted, which is not only inefficient but also labor-intensive. Secondly, once the position of the locating pin hole is determined, it can no longer be adjusted, which brings great inconvenience to the subsequent installation and maintenance of the machine tool.

[0024] The utility model is described in detail below with reference to the accompanying drawings and embodiments.
[0025] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by "up", "down", "left", "right", "inside", "outside", "top" and "bottom" are all based on the directions or positional relationships shown in the accompanying drawings.

[0026] like Figure 1-4 As shown, the utility model provides a column precise positioning mechanism based on inclined plane locking, comprising: an inclined pull block 4 and an inclined push block 7;
[0027] The design of the pull block 4 and the push block 7 is based on the principle of inclined plane locking, and the machine tool column 1 can be precisely fixed and adjusted through the relative movement of the two.
[0028] Specifically, the bevel pull block 4 is designed with a rectangular structure, one side of which is provided with an inclined surface, and the other side is provided with a rectangular groove. The bevel pull block 4 is provided with a tightening screw hole 9, and the push bevel block 7 is also a rectangular structure, one side of which is provided with an inclined surface matching the bevel pull block 4, and the other side opposite to it is also provided with a rectangular groove. The bevel pull block 4 and the push bevel block 7 can realize the effective locking and releasing of the machine tool column 1 through the relative movement of the inclined surfaces;
[0029] The bevel pull block 4 and the bevel push block 7 are respectively embedded in the positioning grooves of the machine tool column 1 and the machine tool slide 2. The inclined surfaces of the bevel pull block 4 and the bevel push block 7 are arranged relatively to each other. Through the interaction between the inclined surfaces, a clamping force perpendicular to the inclined surfaces can be generated in the locked state, thereby firmly fixing the machine tool column 1 in the predetermined position, ensuring that the machine tool column 1 can be stably fixed in the predetermined position in the locked state, avoiding displacement caused by vibration or other external forces during the processing process.
[0030] The fixing block 3 is arranged on the outside of the bevel pulling block 4 and the bevel pushing block 7. The fixing block 3 is connected to the bevel pulling block 4 by a tightening screw 5. The fixing block 3 is composed of two rectangular structures. The size of the rectangular structure at the upper end of the fixing block 3 is larger than that of the rectangular structure at the lower end. Such a design helps to improve the stability and strength of the structure. A plurality of fastening screw holes are provided at the upper end of the fixing block 3. Fastening screws 6 are respectively provided in the plurality of fastening screw holes. On the one hand, the fixing block 3 is fixed to the machine tool column 1 by the fastening screws 6. On the other hand, it is connected to the bevel pulling block 4 by the tightening screws 5. The fixing block 3 ensures that the column precise positioning mechanism based on the inclined surface locking remains stable during operation.
[0031] The rectangular structure at the lower end of the fixing block 3 is respectively provided with a tightening screw hole opposite to the pushing block 7 and a threaded hole through which the tightening screw 5 can pass. The tightening screw 8 is arranged in the tightening screw hole. The tightening screw 5 matches the tightening screw hole 9 on the pulling block 4 and passes through the fixing block 3 to be connected thereto, thereby ensuring that the pulling block 4 can be firmly fixed on the tightening screw 5 and ensuring that the pulling block 4 can be driven to slide in the positioning groove when the tightening screw 5 is rotated;
[0032] The fixing block 3 is provided with a tightening screw 8, which is arranged in the tightening screw hole. The position of the push-bevel block 7 can be adjusted by tightening the tightening screw 8. Tightening the tightening screw 8 can make the push-bevel block 7 move relatively along the inclined surface of the pull-bevel block 4, thereby realizing fine-tuning of the machine tool column 1.
[0033] The following is a detailed introduction to the actual working scenario of a column precision positioning mechanism based on inclined plane locking.
[0034] like Figure 1 As shown, in the actual working process, it is first necessary to assemble the machine tool column 1 and the machine tool slide 2, adjust the position accuracy of the machine tool column 1 and fix it, install the column precise positioning mechanism based on the inclined surface locking, combine the inclined surfaces of the pulling block 4 and the pushing block 7 relatively, and install them in the positioning grooves of the machine tool column 1 and the machine tool slide 2 after combination, and ensure that the pulling block 4 and the pushing block 7 can slide relatively in the positioning groove, fix the fixed block 3 on the machine tool column 1 through a plurality of fastening screws 6, install the tightening screw 5 on the fixed block 3, so that the tightening screw 5 can be screwed into the tightening screw hole 9 provided on the pulling block 4 through the threaded hole provided on the fixed block 3, and ensure that the pulling block 4 can slide in the positioning groove when the tightening screw 5 is rotated, and the tightening screw 8 is installed in the tightening screw hole and pressed against the outer wall of the pushing block 7, and ensure that the pushing block 7 can slide in the positioning groove when the tightening screw 8 is rotated;
[0035] When adjusting, the bevel pull block 4 and the bevel push block 7 are relatively displaced by rotating the tension screw 5 and the tension screw 8, so that the bevel pull block 4 and the bevel push block 7 are gradually tightened with the side of the positioning groove of the machine tool slide 2 to achieve the effect of positioning and locking;
[0036] In actual work, two sets of column precise positioning mechanisms based on inclined plane locking are usually used at the same time. The two sets of column precise positioning mechanisms based on inclined plane locking can realize the position locking of the machine tool column 1 in two directions. When the machine tool column 1 is disassembled and adjusted many times, there will be a certain misalignment between the machine tool column 1 and the positioning groove on the machine tool slide 2, resulting in the original positioning device being unusable. At this time, the inclined pull block 4 and the inclined push block 7 can be adjusted to adapt to the position of the positioning groove on the machine tool slide 2 to achieve the effect of rapid assembly and locking positioning.
[0037] It can be understood that the above-mentioned various embodiments mentioned in the present invention can be combined with each other to form a combined embodiment without violating the principle logic. Due to space limitations, the present invention will not elaborate on them.
[0038] Those skilled in the art will appreciate that, in the above method of specific implementation, the order in which the steps are written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of the steps should be determined by their functions and possible internal logic.
[0039] The utility model provides a column precise positioning mechanism based on inclined surface locking. Through the relative arrangement of the inclined surfaces of the inclined pull block 4 and the inclined push block 7, the precise positioning of the machine tool column 1 can be achieved, ensuring that the machine tool has high precision during the processing. The inclined pull block 4 and the inclined push block 7 are respectively embedded in the positioning grooves of the machine tool column 1 and the machine tool slide 2. Through the cooperation of the inclined surfaces, stable support can be provided to prevent the machine tool column 1 from shifting during the processing. By tightening or loosening the tightening screw 8, the position of the inclined push block 7 can be conveniently adjusted, thereby achieving fine-tuning of the machine tool column 1 to meet different processing requirements. The column precise positioning mechanism based on inclined surface locking has a simple structure and is easy to manufacture and maintain, thereby achieving the purpose of replacing the method of positioning the machine tool by the locating pin in the prior art, and solving the problem that the position of the locating pin hole cannot be adjusted after the machine tool is positioned by the locating pin, which is not conducive to the subsequent installation and maintenance of the machine tool.
