When the worktable is rotated to a certain angle and the indexing head accessory is used, various spiral surfaces can be processed; the three-way feed screw of the universal milling machine is a trapezoidal screw or a ball screw.

[0003] At present, when a universal milling machine is used to process large workpieces, a lifting device is required to lift the large workpiece. However, during the processing, since the large workpiece needs to move along with the processing of the universal milling machine, it is necessary to repeatedly operate the lifting device to put the large workpiece in a suitable position. Although large workpieces can be processed, the operation is relatively cumbersome and inefficient. Based on this, an auxiliary lifting device for the worktable of a universal milling machine is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a universal milling machine table auxiliary lifting device with a simple structure and reasonable design in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] An auxiliary lifting device for a universal milling machine worktable includes a base and legs, wherein rollers are installed at the bottom of the legs, and a fixed cylinder is fixedly connected to the top of the legs, and a lifting box is fixedly connected to the top of the fixed cylinder. A lifting mechanism is installed in the lifting box, and the lifting mechanism is used to adjust the height of a large workpiece.

[0007] As a further optimization scheme of the present invention, the lifting mechanism includes a worm that passes through the lifting box and is rotatably connected to the lifting box. The end of the worm that extends out of the lifting box is rotatably connected to a handle. A lifting screw sleeve is rotatably connected inside the lifting box. The outer wall of the lifting screw sleeve is fixedly connected to a worm wheel. The worm wheel is adapted to the worm. A lifting screw is threadedly connected inside the lifting screw sleeve. The lifting screw passes through the lifting box and is slidably connected to the lifting box through a limiting component.

[0008] As a further optimization scheme of the present invention, the limiting component includes a limiting block and a limiting groove. The limiting block is fixedly connected to the position where the lifting box and the lifting screw are slidingly connected. The limiting groove is opened on the outer surface of the lifting screw, and the limiting groove is adapted to the limiting block.

[0010] As a further optimization solution of the present invention, the limiting plate is adapted to the slide plate, the bottom of the supporting groove is configured to be arc-shaped, and the large workpiece is placed in the supporting groove.

[0011] As a further optimization solution of the present invention, two groups of rollers are provided, and both groups of rollers are adapted to the base.

[0012] The beneficial effect of the present invention is that, through the coordinated use of the lifting mechanism, the base, the rollers and the displacement mechanism, when processing a large workpiece on a universal milling machine, the large workpiece is first placed in the displacement mechanism, and then the height of the large workpiece is adjusted by the lifting mechanism according to the height of the worktable of the universal milling machine.

[0019] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example

[0021] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, an auxiliary lifting device for a universal milling machine table includes a base 1 and a leg 2. Rollers 3 are installed at the bottom of the leg 2. Two groups of rollers 3 are provided. Both groups of rollers 3 are adapted to the base 1. A fixed cylinder 4 is fixedly connected to the top of the leg 2. A lifting box 5 is fixedly connected to the top of the fixed cylinder 4. A lifting mechanism is installed in the lifting box 5. The lifting mechanism is used to adjust the height of large workpieces. A displacement mechanism is installed on the top of the lifting mechanism. The large workpiece is placed in the displacement mechanism.

[0022] When in use, the lifting device is prevented from being placed to the side of the universal milling machine, and then the large workpiece can be placed in the displacement mechanism. At this time, the height of the large workpiece can be adjusted through the lifting mechanism according to the height of the worktable of the universal milling machine. After reaching the appropriate position, the large workpiece can be processed by the universal milling machine.

[0023] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the lifting mechanism includes a worm 6 that passes through the lifting box 5 and is rotatably connected to the lifting box 5. One end of the worm 6 extends out of the lifting box 5 and is rotatably connected to a handle 7. A lifting screw sleeve 9 is rotatably connected in the lifting box 5. The outer wall of the lifting screw sleeve 9 is fixedly connected to a worm wheel 8. The worm wheel 8 is adapted to the worm 6. A lifting screw 10 is connected to the lifting screw sleeve 9 through a thread. The lifting screw 10 passes through the lifting box 5 and is slidably connected to the lifting box 5 through a limiting component. The limiting component includes a limiting block 11 and a limiting groove 12. The limiting block 11 is fixedly connected to the position where the lifting box 5 is slidably connected to the lifting screw 10. The limiting groove 12 2 is provided on the outer surface of the lifting screw 10, and the limit groove 12 is adapted to the limit block 11. The displacement mechanism includes a lifting plate 13 fixedly connected to the top of the lifting screw 10. Two slide bars 14 are fixedly connected to the top of the lifting plate 13. The ends of the two slide bars 14 are fixedly connected to the limit plate 15. The outer surface of the slide bar 14 is slidably connected to a slide plate 16. Two supporting plates 17 are fixedly connected to the top of the slide plate 16. Both supporting plates 17 are provided with a supporting groove 18. The limit plate 15 is adapted to the slide plate 16. The bottom of the supporting groove 18 is set to be arc-shaped. Large workpieces are placed in the supporting groove 18.

[0024] When processing a large workpiece, first place the large workpiece in the supporting groove 18, then adjust the height of the large workpiece as needed, rotate the worm 6 by holding the handle 7, and then drive the lifting screw sleeve 9 to rotate through the worm gear 8, so that the lifting screw 10 moves up and down under the action of the limit block 11 and the limit groove 12, thereby achieving the purpose of adjusting the height of the large workpiece so that the height of the large workpiece is compatible with the height of the universal milling machine worktable, and then the large workpiece can be processed by the universal milling machine. During processing, when it is necessary to move the large workpiece forward and backward, the roller 3 moves forward and backward on the base 1 to achieve the purpose of moving the large workpiece forward and backward, and when it is necessary to move the large workpiece left and right, the slide 16 slides left and right on the slide rod 14 to achieve the purpose of moving the large workpiece left and right, and in the process of moving, through the setting of the two supporting grooves 18, the large workpiece can only be translated to prevent the large workpiece from angular deflection, thereby ensuring the accuracy of the processing of the large workpiece, facilitating the movement of the large workpiece during the processing of the large workpiece, reducing the burden on personnel, improving the processing efficiency of the large workpiece, and at the same time, less safety hazards.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
