It is understood that a reinforcing structure is arranged in a bed body of the conventional drilling and tapping machine, and although the reinforcing structure has a certain supporting force for the Y-axis movement assembly and the workbench, the structure of the reinforcing structure is too complex, the reinforcing structure cannot be arranged corresponding to the Y-axis movement assembly and the workbench, so that the design complexity and the process difficulty of the bed body are greatly increased, and it is not convenient to achieve the light weight of the bed body, in order to solve the above technical problems, in this embodiment, as shown in fig. 1, 4, 5, 6, 7, 8 and 9, the first bed body 11 includes a first mounting seat 111 and two first outer side plates 112 extending along the Y-axis direction, the Y-axis guide rail 61 is arranged at the top end of the first mounting seat 111, the first outer side plates 112 are arranged at the bottom of the outer side of the first mounting seat 111, and the two first outer side plates 112 are arranged in a shape of a Chinese character 'ba'. From this, the brill of this embodiment attacks the machine and has following advantage:

(1) the first bed body 11 comprises a first mounting seat 111 and two first outer side plates 112 extending along the Y-axis direction, the Y-axis guide rail 61 is arranged at the top end of the first mounting seat 111, the first outer side plates 112 are arranged at the bottom of the outer side of the first mounting seat 111, and the two first outer side plates 112 are arranged in a shape like a Chinese character 'ba', wherein the upper part of each first outer side plate is narrow and the lower part of each first outer side plate is wide, so that the rigidity and the strength of the first bed body 11 are favorably improved, the saddle 7 and the workbench 400 are stably supported, and the first bed body 11 is prevented from collapsing due to insufficient rigidity of the first bed body 11;

in addition, the first outer side plate 112 has a simple structure, and the first bed body 11 does not need to be provided with a reinforcing structure with a complex structure and is used for supporting the saddle 7 and the workbench 400, so that the design and manufacture of the first bed body 11 are facilitated, and the lightweight design of the first bed body 11 is realized;

(2) when the main shaft assembly 5 does not process a workpiece, under the action of gravity of the tool magazine 8, the main shaft assembly 5 receives a certain amount of pulling force, the main shaft assembly 5 pulls the upright column 2 forward, the main shaft assembly 5 tends to tilt forward, in order to prevent the upright column 2 from tilting forward, the first bed body 11 of the embodiment is located at the front side of the second bed body 12, the first outer side plate 112 is connected with the second bed body 12, the first outer side plate 112 applies a certain supporting force to the second bed body 12, and the second bed body 12 is not prone to tilting forward.

In some embodiments, as shown in fig. 1, 8 and 9, the rear side of the first bed body 11 is disposed flush with the front side of the column 2, or the rear side of the first bed body 11 is located behind the front side of the column 2. Therefore, the first outer side plate 112 extends from the front to the back to the column 2, so as to ensure that the first bed body 11 has enough supporting force for the column 2;

tests show that when the rear side of the first bed body 11 is flush with the front side of the column 2, stress concentration is likely to occur on the rear side of the first outer side plate 112 and the rear side of the first mounting seat 111, and after long-term use, fatigue cracks are generated on the rear side of the first outer side plate 112 and the rear side of the first mounting seat 111, so that the column 2 cannot be stably supported by the first bed body 11;

as a preferable technical solution, the rear side of the first bed body 11 is located behind the front side of the column 2, so that the requirement that the first bed body 11 can stably support the column 2 can be met, fatigue cracks are not easily generated on the rear side of the first outer side plate 112 and the rear side of the first mounting seat 111, and the service life of the first bed body 11 is ensured.

Therefore, compared with the first bed body 11 which is subjected to the dynamic loads of the saddle 7 and the workbench 400, the second bed body 12 is mainly subjected to the gravity of the column 2, the dynamic load applied to the second bed body 12 is small, and the second outer side plate 122 can be vertically arranged.

In some embodiments, as shown in fig. 4, the second bed body 12 further includes a rear side plate 124, and the rear side plate 124 is disposed between the rear sides of the two second external side plates 122, so as to further enhance the connection strength of the two second external side plates 122.

In some embodiments, as shown in fig. 1, 5, 6 and 7, the drilling and tapping machine further comprises two first supporting seats 9, two second supporting seats 10 and two third supporting seats 20, wherein the first supporting legs 30 are connected to the first supporting seats 9, the second supporting seats 10 and the third supporting seats 20;

the two first supporting seats 9 are respectively disposed in front of the two first outer side plates 112, the two second supporting seats 10 are respectively disposed behind the two second outer side plates 122, and the third supporting seat 20 is disposed across the first outer side plates 112 and the second outer side plates 122. Therefore, the first support seat 9, the second support seat 10 and the third support seat 20 are all used for fixing the first support leg 30, so that the connection between the first bed body 11 and the ground and the connection between the second bed body 12 and the ground are more stable; meanwhile, the third support seat 20 connects the first outer side plate 112 and the second outer side plate 122 together to improve the connection strength between the first outer side plate 112 and the second outer side plate 122;
