DETAILED DESCRIPTION

[0049] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0050] like Figure 1 and Figure 2 As shown, the hidden moving wheel structure of the mechanical machine tool comprises a base 11 constituting the bottom area of ​​the machine tool 1, and a moving component is arranged in the inner cavity of the base 11;

[0051] The moving assembly includes a driving part 2, a transmission part 4 and a moving part 3. The driving part 2 is located at the center of the inner cavity of the base 11. Two transmission parts 4 are rotatably connected to each other on both sides of the driving part 2. A moving part 3 is arranged on the end of each transmission part 4. The four moving parts 3 also constitute four supporting points during the movement of the machine tool 1.

[0052] A fulcrum is provided on the surface of the transmission part 4 near the side of the moving part 3, and the fulcrum is fixedly connected to the side wall of the inner cavity of the base 11. The transmission part 4 rotates around the fulcrum as the center of the circle, and the transmission part 4 and the driving part 2 and the moving part 3 located at both ends of the transmission part 4 form a lever structure;

[0053] The moving part 3 is provided with moving wheels 35 that can help the machine tool 1 move;

[0054] The driving part 2 drives the transmission part 4 to rotate around the fulcrum.

[0055] The mobile assembly is used to make the machine tool 1 mobile, which is convenient for carrying the machine tool 1. The mobile assembly is composed of a driving part 2, a transmission part 4 and a mobile part 3, and the driving part 2, the transmission part 4 and the mobile part 3 together constitute a lever structure. By utilizing the lever principle, the driving part 2 drives the four mobile parts 3 to be ejected synchronously through the four transmission parts 4 at the same time, thereby reducing the power required for the mobile assembly to be deployed. At the same time, the pressure directly borne by the base 11 after the mobile parts 3 lift up the machine tool 1 is dispersed through the fulcrum. The pressure borne by the base 11 is reduced by dispersing the force points, thereby preventing the base 11 from being deformed due to excessive concentration of pressure on the base 11.

[0056] Embodiment 1

[0057] As one of the embodiments of this technical solution, Figure 2 and 3 As shown, the driving part 2 includes a mounting frame 21, and the mounting frame 21 is fixed on the inner cavity side wall of the base 11. A driving member 22 is fixed on the mounting frame 21, and a lifting plate 23 is fixed on the top of the driving member 22. The driving member 22 drives the lifting plate 23 to rise and fall, and the lifting plate 23 is interconnected with the transmission part 4.

[0058] It should be noted that the driving member 22 is a hydraulic jack or a hydraulic push rod, and the moving end at the top of the driving member 22 is fixedly connected to the lifting plate 23 .

[0059] When the driving member 22 is a manual hydraulic jack, a through groove needs to be opened on one of the side walls of the base 11, and the through groove is used for placing the hydraulic rod force rod.

[0060] like Figure 3 and Figure 4 As shown, the transmission part 4 includes a transmission rod 41, one end of which is rotatably connected to the bottom side wall of the lifting plate 23, and the other end of the transmission rod 41 is connected to a fulcrum, and the fulcrum includes a connecting ring 42, and a first bearing shaft 45 is inserted into the interior of the connecting ring 42. The connecting ring 42 can rotate on the surface of the first bearing shaft 45, and the transmission rod 41 and the driving rod 43 are fixed on the surface of the connecting ring 42. The driving rod 43 and the transmission rod 41 are respectively located at two ends of the connecting ring 42;

[0061] A downward pressing arc plate 44 is fixed to the bottom of the end of the driving rod 43 , and the downward pressing arc plate 44 overlaps the moving part 3 .

[0062] When the driving part 2 drives the lifting plate 23 to rise, the lifting plate 23 drives the transmission rod 41 to rotate along the first bearing shaft 45, and drives the driving rod 43 to rotate through the connecting ring 42. The downward pressure arc plate 44 on the driving rod 43 moves down and begins to contact the moving part 3, so that the moving part 3 moves down and pushes out of the base 11, that is, the machine tool 1 is lifted up by the moving part 3.

[0063] Further, the moving part 3 includes a lifting column 31, the surface of the lifting column 31 is sleeved with a guide shell 32, the guide shell 32 is fixed on the inner cavity side wall of the base 11, the lifting column 31 slides up and down inside the guide shell 32, a connecting frame 33 is fixed on the top of the lifting part, and a second guide telescopic rod 34 is fixed on the top of the connecting frame 33, the second guide telescopic rod 34 is fixed on the inner cavity side wall of the base 11, and the second guide telescopic rod 34 is arranged vertically;

[0064] The driving rod 43 extends into the connecting frame 33 and the lower arc plate 44 at the end of the driving rod 43 is located at the top of the lifting column 31 and can overlap with it, and the outer arc surface of the lower arc plate 44 overlaps with the top of the lifting column 31;

[0065] A moving wheel 35 is installed at the bottom of the lifting column 31 .

[0066] The downward pressure arc plate 44 pushes the lifting column 31 to slide downward inside the guide shell 32 during the downward movement, thereby lifting the machine tool 1 through the lifting column 31 and then pushing the machine tool 1 to move, and the moving wheels 35 at the bottom of the lifting column 31 provide a structural basis for the movement of the machine tool 1.

[0067] Preferably, a limit cover 46 is provided on the top of the transmission rod 41, and the limit cover 46 is on the surface of the transmission rod 41. A plurality of guide telescopic arc rods 47 with arc-shaped structures are fixed on the limit cover 46, wherein at least one guide telescopic arc rod 47 is sleeved with a first spring, and the center of the guide telescopic arc rod 47 coincides with the center of rotation of the transmission rod 41.

[0068] When the transmission rod 41 rotates, it pushes the limit cover 46 to move, the guide telescopic arc rod 47 contracts, and the first spring contracts. The damping provided by the first spring on the surface of the guide telescopic arc rod 47 can limit the lateral shaking of the transmission rod 41 during the rotation process, so that the moving part 3 does not generate additional shaking in the process of lifting the machine tool 1, avoiding adverse effects on the machine tool 1.

[0069] The limiting cover 46 is in a "door"-shaped structure, and a clamping assembly 8 for assisting the limiting transmission rod 41 is also arranged in the inner cavity of the limiting cover 46;

[0070] The clamping assembly 8 includes a lap plate 81, which can overlap with the transmission rod 41, and a driving plate 82 is fixed to the top of the lap, and the driving plate 82 is connected to the inner wall of the limit cover 46 through a third guide telescopic rod;

[0071] Transmission units are provided on both sides of the driving plate 82, and the transmission units include a first connecting rod 84, one end of which is fixed with an inclined plate 83 overlapping with the driving plate 82, and the other end of the first connecting rod 84 is fixed with a rotating ring 85, and a second connecting rod 86 is fixed on the rotating ring 85, and the end of the second connecting rod 86 is rotatably connected to a fixed plate 88, and the fixed plate 88 can overlap with the side wall of the transmission rod 41;

[0072] The second bearing shaft 87 is inserted into the rotating ring 85. The rotating ring 85 rotates on the surface of the second bearing shaft 87. The second bearing shaft 87 is fixed to the inner wall of the limiting cover 46 through a rod.

[0073] A coil spring is provided at the rotation connection between the second connecting rod 86 and the fixed plate 88, and the coil spring makes the fixed plate 88 in an inclined state when not subjected to external force. Figure 7 As shown, the fixing plate 88 is tilted toward a side away from the transmission rod 41 when no external force is applied.

[0074] Another coil spring is arranged at the connection between the second bearing shaft 87 and the rotating ring 85, or a second spring is arranged on the surface of the third guide telescopic rod. The coil spring or the second spring is used to put the clamping assembly 8 in an expanded state to prevent the transmission rod 41 from entering the limit cover 46. The second spring is not shown in the figure.

[0075] During the rotation process, the transmission rod 41 extends into the limiting cover 46, and the moving transmission rod 41 begins to overlap with the lap plate 81. The continuously moving transmission rod 41 pushes the lap plate 81 and the driving plate 82 to move, and the moving driving plate 82 pushes the inclined plate 83 to move, thereby causing the first connecting rod 84 connected to the inclined plate 83 to rotate, and the first connecting rod 84 drives the second connecting rod 86 to rotate through the rotating ring 85. During the rotation process, the second connecting rod 86 drives the fixed plate 88 to be pressed tightly against the transmission rod 41, thereby clamping the transmission rod 41, and cooperating with the limiting cover 46 to limit the transmission rod 41 to prevent the transmission rod 41 from shaking.
