Description

Technical Field

[0001] The utility model relates to the technical field of milling machines, in particular to a leveling device for milling machines. Background Art

[0002] Milling machines mainly refer to machine tools that use milling cutters to process various surfaces of workpieces. Usually, the milling cutter mainly moves in rotation, and the movement of the workpiece and the milling cutter is the feed motion. Milling machines can process planes, grooves, toothed parts, spiral surfaces and various curved surfaces. In addition, they can also be used for processing the surface of rotating bodies, inner holes and cutting, etc.

[0003] However, when using a milling machine to process regular workpieces, the placement plate needs to be in a horizontal state, otherwise the workpiece will not be placed horizontally, resulting in unstable processing. For some workpieces with a certain inclination angle on the top, it is necessary to adjust the angle of the placement plate to level and fix the workpiece. Therefore, how to solve this problem is what we need to consider. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a leveling device for a milling machine, which, through the cooperation of structures such as a worm gear, a worm and a knob, enables a placement plate to move and then adjust the angle of the placement plate, thereby leveling and fixing some workpieces with a certain inclination angle on the top.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The top of the two wheels is provided with a toothed structure, and the toothed structure is designed so that the two wheels are fixed with a toothed structure and the toothed structure can be adjusted accordingly.

[0007] Preferably, both ends of the worm screw penetrate the corresponding fixing blocks and extend to the outside, and both ends of the worm screw are fixedly connected with knobs.

[0008] Preferably, outer side walls of the two knobs are both covered with protective covers, and the two protective covers are both made of rubber material.

[0009] Preferably, a connecting rod is fixedly connected to the side wall of the rotating rod, and a rubber layer is provided on the connecting rod.

[0010] Preferably, a plurality of protective grooves are provided at the lower end of the base, and the plurality of anti-slip grooves are all triangular in shape.

[0011] Preferably, the movable plate is composed of a horizontal plate and two vertical plates, and the two vertical plates cooperate with corresponding arc-shaped plates.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. Through the coordination of the worm wheel, worm and knob, the worm is rotated by turning the knob. Under the meshing relationship of the worm wheel, the moving plate slides with the placement plate on the two arc-shaped plates, thereby adjusting the angle of the placement plate, so that some workpieces with a certain inclination angle on the top can be leveled and fixed, thereby improving the processing accuracy;

[0014] 2. By cooperating with the rotating sleeve, rotating rod and adjusting plate and other structures, the adjusting plate is rotated to the upper surface of the placement plate. By observing the gap between the adjusting plate and the upper surface of the placement plate, the horizontality of the upper surface of the placement plate is judged, and the placement plate is adjusted to a horizontal state to process the horizontal workpiece.
