[0031] As used herein, the singular forms "a", "an" and "the" may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms "comprising / including" or "having" etc. specify the presence of the stated features, wholes, steps, operations, components, parts or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0032] Please refer to Figure 1 , a CNC machine tool, comprising:

[0033] A machine tool main body 1 and a mounting plate 2, and a rectangular hole is provided on the surface of the mounting plate 2;

[0034] Based on the above, the setting of the rectangular hole enables the first step 3 to be connected to the mounting plate 2 through a gasket and a nut, and the receiving ladder can be vertically moved by loosening the nut, so as to make the receiving ladder applicable to the case where there is a bracket or a gasket at the bottom of the CNC machine tool.

[0035] As Figure 2 and Figure 5 shown, the first step 3 is disposed between the mounting plate 2 through a nut and a gasket, and includes a first positioning groove 33 and a first transverse hole 34;

[0036] The first step 3 includes first half-step blocks 31 which are connected to each other by screws. On opposite sides of the first half-step blocks 31, there are two first vertical plates 32 provided respectively. On the lower surface of the first vertical plates 32, there are first positioning grooves 33. The top wall of the inner side of the first positioning grooves 33 is an arc-shaped groove surface. On the opposite sides of the first half-step blocks 31, there are first transverse holes 34 and threaded posts 35 provided respectively. The threaded posts 35 penetrate through the rectangular holes and are connected to the mounting plate 2 through nuts and washers.

[0037] Based on the above, due to the setting of the first positioning groove 33, the positioning block 6 can be snapped into the inside of the first positioning groove 33 under the action of the elastic piece 7, thereby fixing the positions of the second step 4 and the third step 5. The setting of the threaded posts 35 enables the first step 3 to be fixedly connected to the mounting plate 2. The setting of the first transverse holes 34 enables the second step 4 to only move horizontally and the movement path is restricted.

[0038] As Figure 2 and Figure 6 shown, the second step 4 is arranged between the first steps 3 and includes a second positioning groove 43, second transverse holes 44, first guide posts 45 and first mounting grooves 46. Among them,

[0039] The first guide posts 45 extend into the inside of the first transverse holes 34.

[0040] The second step 4 includes second half-step blocks 41 which are connected to each other by screws. On opposite sides of the second half-step blocks 41, there are two second vertical plates 42 provided respectively. At the bottom ends of the second vertical plates 42, there are second positioning grooves 43. The top wall of the inner side of the second positioning grooves 43 is an arc-shaped groove surface. On the upper surfaces of the second half-step blocks 41, there are first mounting grooves 46. On the opposite sides of the second half-step blocks 41, there are second transverse holes 44 and first guide posts 45 provided respectively.

[0041] Based on the above, the second positioning groove 43 plays the same role as the first positioning groove 33, and the second transverse holes 44 and the first transverse holes 34 also play the same role. The first transverse holes 34 and the first guide posts 45 cooperate with each other to restrict the movement path of the second step 4 and avoid the situation of detachment during the movement of the second step 4. The setting of the first mounting grooves 46 enables the positioning block 6 and the elastic piece 7 to have sufficient space for movement.

[0042] As Figure 2 and Figure 7 shown, the third step 5 includes third half-step blocks 51, second guide posts 52 and second mounting grooves 54. Among them,

[0043] The second guiding post 52 extends into the interior of the second transverse hole 44. The third step 5 includes third half-step blocks 51 which are interconnected by screws. Second guiding posts 52 are provided on the opposite sides of the third half-step blocks 51. A second mounting groove 54 is provided on the upper surface of the third half-step blocks 51. A grip 53 is provided on the surface of the third half-step blocks 51 away from the machine tool body 1.

[0044] Based on the above, the second guiding post 52 cooperates with the second transverse hole 44, restricting the movement path of the third step 5 and preventing the third step 5 from detaching during movement. The effect of the second mounting groove 54 is the same as that of the first mounting groove 46.

[0045] As Figure 3 、 Figure 4 、 Figure 8 and Figure 9 shown, positioning blocks 6 are respectively provided inside the first mounting groove 46 and the second mounting groove 54 and extend into the interior of the first positioning groove 33 and the second positioning groove 43 respectively. The positioning block 6 includes a block body 61. An arc surface 63 is provided at the top of the block body 61. Limiting grooves 62 are provided on both sides at the bottom of the block body 61. Elastic sheets 7 are provided inside the limiting grooves 62.

[0046] Elastic sheets 7 are respectively provided inside the first mounting groove 46 and the second mounting groove 54 and are in contact with the positioning block 6.

[0047] Based on the above, the setting of the limiting grooves 62 restricts the position of the elastic sheets 7, preventing the elastic sheets 7 from shifting during the use of the device. The arc surface 62 cooperates with the first positioning groove 33 and the second positioning groove 43. When the positioning block 6 is forced to move, there is a vertical component force after the positioning block 6 is squeezed against the inner surfaces of the first positioning groove 33 and the second positioning groove 43, enabling the positioning block 6 to move vertically. The elastic sheets 7 are compressed under force when the positioning block 6 moves vertically, generating a reverse elastic force. When the external force on the positioning block 6 is removed, it will reset under the action of the elastic force.

[0048] When this embodiment is actually used, the first step 3 is fixed between the mounting plates 2 through nuts and gaskets. When it is necessary to deploy the remaining two steps, the grip 53 can be held and the third step 5 can be pulled. When the third step 5 is pulled, the positioning block 6 is squeezed against the second positioning groove 43. At this time, the positioning block 6 moves downward and squeezes the elastic sheet 7. When the positioning block 6 separates from the second step 4, it resets under the action of the elastic force.

[0049] Continue to pull the third step 5 until the positioning block 6 contacts the second step 4, and then snap into the interior of another second positioning groove 43. At this time, the expansion of the third step 5 is realized. Similarly, the second step 4 can be expanded. The expanded storage ladder can be directly used, facilitating the staff to step on it;

[0050] When the storage ladder is not needed, hold the grip 53 and push the third step 5 to make the third step 5 retract into the second step 4. After the retraction is completed, continue to push the third step 5 to drive the second step 4 to move for retraction. After the two steps are retracted, the retraction of the storage ladder is completed;

[0051] If there are structures such as brackets or gaskets installed below the machine tool main body 1 during use, loosen the nut so that the first step 3 can move vertically along the rectangular hole, thereby ensuring that the storage ladder contacts the ground;

[0052] This CNC machine tool is provided with a storage ladder on its surface compared with the traditional machine tool. The storage ladder can be expanded during the use of the equipment, facilitating the staff to operate the CNC machine tool. If it is not needed, it can be retracted. The retracted storage ladder occupies a small space and will not hinder the staff's walking.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
