Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a rotatable machine tool base. Background Art

[0002] Machine tools are indispensable equipment in mechanical processing. They are large in size, heavy in weight and difficult to move. The machine tool base, as the main body of the entire machine tool, supports all the weight of the machine tool and plays an important role in the entire machine tool. It has strong stability and is earthquake-resistant. However, in current machine tools, huge machine tools are difficult to move. When the machine tool needs to change position to work, it brings great trouble to the workers.

[0003] Traditional devices have some disadvantages during use. For example, large machine tools are equipped with tracks at the bottom for easy movement. However, when turning, the machine tools with tracks at the bottom will always produce a large area of ​​friction with the ground. The impact is not significant on general sandy ground, but most factory floors today are made of cement. When the tracks rub against the cement floor, not only will the ground be damaged, but the large area of ​​friction may also cause sparks.

[0004] Therefore, the present application provides a rotatable machine tool base to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a rotatable machine tool base to solve the tooling for drilling holes in disc-type workpieces. Generally, a positioning component and a locking component are required to cooperate with each other. The positioning component and the locking component are complicated to manufacture and are also troublesome to install and remove, which increases the manufacturing cost.

[0009] Preferably, when the movable end of the electric telescopic rod is extended, the mounting plate is in contact with the ground, and when the movable end of the electric telescopic rod is retracted, the mounting plate is separated from the ground.

[0010] Preferably, when the piston end of the hydraulic jack is extended, the adsorption surface of the suction cup contacts the lower end surface of the bottom rotating disk, and when the piston end of the hydraulic jack is contracted, the adsorption surface of the suction cup is separated from the lower end surface of the bottom rotating disk.

[0011] Preferably, when the piston end of the hydraulic jack is extended to the top, the rolling surface of the crawler track is off the ground.

[0012] Preferably, a suction cup is fixedly mounted on the piston end of the hydraulic jack, and a rotating handle is provided on the side wall of the crawler chassis.

It is simpler, more convenient and easier to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1-Figure 4 As shown, the embodiment of the utility model provides a rotatable machine tool base, including a base 10, a crawler chassis 11 is welded and fixed below the base 10, crawlers 12 are arranged on both sides of the lower end surface of the crawler chassis 11, a top rotating plate 13 is welded and fixed at the center of the lower end surface of the crawler chassis 11, the lower end surface of the top rotating plate 13 is rotatably connected to the bottom rotating plate 14, an electric telescopic rod 15 is fixedly installed at the center of the lower end surface of the bottom rotating plate 14 by bolts, a connecting plate 16 is welded and fixed at the movable end of the electric telescopic rod 15, mounting plates 17 are welded and fixed on the four side walls of the connecting plate 16, and a hydraulic top is fixedly installed on the mounting plate 17 by bolts Rod 18, the piston end of the hydraulic push rod 18 is connected with a suction cup 19. During specific use, when the machine tool needs to be turned, the electric telescopic rod 15 is first used to drive the connecting plate 16 to move up and down, and then the connecting plate 16 drives the mounting plate 17 to move down synchronously. When the mounting plate 17 moves down to a position in contact with the ground, the hydraulic push rod 18 is started, so that the hydraulic push rod 18 drives the suction cup 19 to vertically adsorb the crawler chassis 11 upward, and then the hydraulic push rod 18 lifts the machine tool. Because the top rotating disk 13 is rotatably connected with the bottom rotating disk 14, the machine tool is turned around by manually rotating the machine tool to achieve a turning effect.

[0031] As an implementation method in this embodiment, Figure 2As shown, the top rotating disk 13 is provided with a driving mechanism, which includes a driven gear 20 fixedly sleeved on the outer wall of the top rotating disk 13, a driving motor 21 is fixedly installed on one of the mounting plates 17 by bolts, a rotating shaft 22 is fixedly installed on the output end of the driving motor 21 by bolts, a driving gear 23 is fixedly sleeved on the top outer wall of the rotating shaft 22, and the driving gear 23 is meshed and connected with the driven gear 20.

[0032] In this embodiment, Figure 2 As shown, when the movable end of the electric telescopic rod 15 is extended, the mounting plate 17 contacts the ground, and when the movable end of the electric telescopic rod 15 is retracted, the mounting plate 17 is separated from the ground. In this way, during the normal operation of the machine tool, the mounting plate 17 will not rub against the ground.

[0033] In this embodiment, Figure 2 As shown, when the piston end of the hydraulic push rod 18 is extended, the adsorption surface of the suction cup 19 contacts the lower end surface of the bottom rotating disk 14, and when the piston end of the hydraulic push rod 18 is contracted, the adsorption surface of the suction cup 19 is separated from the lower end surface of the bottom rotating disk 14.

[0035] In this embodiment, Figure 1 As shown, a suction cup 19 is fixedly mounted on the piston end of the hydraulic push rod 18 by bolts, and a rotating handle 111 is arranged on the side wall of the crawler chassis 11, so that the hand has a force area during manual steering.

[0036] In this embodiment, the connecting plate 16 and the mounting plate 17 are integrally formed, and the connection between the two components is more stable.

[0037] In this embodiment, Figure 2 and Figure 4 As shown, a control switch 30 and a battery 31 are fixedly installed on one side of the crawler chassis 11 by bolts.

[0038] The technical solution provided by the utility model is as follows: when the machine tool needs to be turned, the connecting plate is first driven to move up and down by the electric telescopic rod, and then the connecting plate drives the mounting plate to move downward synchronously. When the mounting plate moves down to a position in contact with the ground, the hydraulic push rod is started to drive the suction cup to vertically adsorb the crawler chassis upward, and then the hydraulic push rod lifts the machine tool. Since the top rotating disk is rotatably connected with the bottom rotating disk, the machine tool is turned around by manually rotating the machine tool, thereby achieving a turning effect.

[0039] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.
