Description

Technical Field

[0001] The utility model relates to the field of machine tool support structures, in particular to a double-layer support structure for a CNC machine tool bed. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. Since CNC machine tools will vibrate when in use, in order to protect the ground and the machine itself, the CNC machine tools will be used in conjunction with the support structure. The existing machine tool bed support structure is mainly based on horizontal and vertical ribs and the traditional rib design, which will lead to insufficient rigidity of the machine tool bed. Due to shaking during heavy cutting and high-speed cutting, such a support structure will cause the machine tool to shake, which in turn leads to unstable machining accuracy. Utility Model Content

[0011] Technical effects and advantages of the utility model:

[0012] The utility model firstly utilizes the top bed ribs and the bottom bed ribs to form a double-layer structure, and then a supporting structure is arranged between the middle parts of the opposite sides of the top bed ribs and the bottom bed ribs, and the strength support of the trapezoidal structure is strengthened by the first diagonal bracing ribs, the first supporting ribs, the second supporting ribs, the second diagonal bracing ribs and the top layer ribs, so that the strength of the entire bed support structure is higher.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] The utility model provides Figure 1 The double-layer support structure of the CNC machine tool bed shown in the figure includes a top bed rib 1 and a bottom bed rib 6. A support mechanism is arranged between the middle parts of the opposite sides of the top bed rib 1 and the bottom bed rib 6. The support mechanism includes a first diagonal support rib 3 and a second diagonal support rib 4. The bottoms of the first diagonal support rib 3 and the second diagonal support rib 4 are respectively provided with a first support rib 601 and a second support rib 602.

[0017] Specifically, the first oblique bracing rib 3, the first supporting rib 601, the second supporting rib 602, the second oblique bracing rib 4 and the top layer rib 101 are sequentially arranged end to end to form a trapezoidal structure.

[0018] It should be noted that the support form of the traditional machine tool support mechanism is a horizontal support structure, while in the present solution, the first diagonal support rib 3, the first support rib 601, the second support rib 602, the second diagonal support rib 4 and the top rib 101 are sequentially arranged end to end to form a trapezoidal structure. Through such a trapezoidal support structure, the support strength of the entire support mechanism is improved. By using such a structural shape setting, the rigidity of the bed support structure is increased by 50%. In this way, the bed support structure is more stable when supporting machine tool processing, thereby ensuring the stability of machine tool processing.

[0019] Furthermore, the thickness of the first diagonal bracing rib 3, the first supporting rib 601, the second supporting rib 602, the second diagonal bracing rib 4 and the top layer rib 101 are all set to be 12-20 mm.

[0020] It should be noted that since the thickness of the support ribs of the traditional machine tool support structure is 12 mm, in this solution, by increasing the thickness of the first diagonal support rib 3, the first support rib 601, the second support rib 602, the second diagonal support rib 4 and the top rib 101 to 12-20 mm, the thickness of the entire bed support mechanism is made thicker, thereby ensuring the strength of the overall structure of the support mechanism.

[0021] A top rib 101 is arranged between the top of the first diagonal bracing rib 3 and the top of the second diagonal bracing rib 4. A support pad 2 is arranged at the top of the top bed rib 1 and at both ends of the top rib 101.

[0022] Specifically, a diagonal brace 5 for stabilizing the support structure is arranged between the two ends of the top bed rib 1 and the bottom bed rib 6. Through the design of the diagonal brace 5, the double-layer structure combination support of the top bed rib 1 and the bottom bed rib 6 is more stable. At the same time, by utilizing such a structural design, the top bed rib 1, the bottom bed rib 6 and the diagonal brace 5 also form a trapezoidal structure, which further improves the stability of the support structure.

[0023] Furthermore, support blocks 8 are provided at both ends of the bottom of the bottom bed rib 6, and the support blocks 8 are used for cushioning the entire supporting structure.

[0024] Furthermore, bolts 7 for connecting the top of the support block 8 and the two ends of the bottom bed rib 6 are provided between the two ends.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
