Description

Technical Field

[0001] The utility model belongs to the technical field of machining, and relates to an intelligent device with digital control for three-way adjustment. Background Art

[0002] At present, in the process of manufacturing and detecting and adjusting auto parts, the Z-direction positioning surface mainly realizes its function through the assembly of a connecting block and a positioning block. Its adjustment method mainly relies on three-coordinate detection, and a fitter manually adds or subtracts gaskets to achieve the positioning accuracy. Manually adding or subtracting gaskets has the following disadvantages: (1) It is necessary to prepare gaskets of various specifications and shapes; (2) There are many types and specifications of processed gaskets, which takes a long time; (3) When adding or subtracting gaskets, the positioning surface will be inclined, and positive and negative deviation values will appear on the same positioning surface, etc.; the adjustment is slow, the cost is high, and the efficiency is low. Summary of the Invention

[0003] The purpose of the utility model is to provide a digital control lifting mechanism device, which uses a digital control lifting mechanism to import design data into software through wireless transmission, and detects the deviation of positioning points through three coordinates, so as to achieve the numerical and precision requirements of the design at each position simultaneously.

[0004] The technical solution of the utility model is as follows:

[0005] Four ball screws are vertically fixed at the four corners of the nut fixing seat to ensure the connection between the ball screw and the nut. The motor is fixed on the vertical center line below the nut fixing seat through the motor seat. A reduction gear, a bearing and a motor connecting seat are installed in the box body A. The motor is meshed and driven with the four ball screws through the reduction gear to ensure the center distance of the ball screws, so that the ball screws can move up and down simultaneously. The box body B is used to fix the positioning points. The box body A and the box body B are connected and fixed through two positioning pins to ensure the accuracy of connecting the positioning blocks.

[0006] The beneficial effects of the utility model are: 1. Low cost: The cost is reduced by using a digital control lifting mechanism, mainly in terms of raw materials, adjustment, etc.; Raw materials: Save adjustment gaskets of various specifications and shapes; Adjustment: No need for manual adjustment by a fitter, and multiple positions can be adjusted simultaneously through circuit board control; 2. High precision: The digital control lifting mechanism has high self-precision, and the adjustment precision reaches 0.02 mm. Using four ball screws to move simultaneously can ensure that the positioning surface is not inclined and there will be no positive and negative extreme deviations; 3. Automation: The digital control lifting mechanism is controlled by a circuit board, and the deviation value is imported through a wireless system, so as to achieve simultaneous and precise adjustment to the designed required position, with high efficiency and low labor cost.
