Description

Technical Field

[0001] The present invention relates to the technical field of workpiece positioning, and particularly relates to a pilot positioning rotary workstation that supports the placement of the special-shaped bottom surface of an electric porcelain. Background Art

[0002] At present, the external glazing process of the blank of the post insulator electric porcelain is basically a pure manual operation. Due to the large mass and fragility of the blank of the post insulator, and the uneven upper and lower cross-sections, the electric porcelain blank can only be fixed at the upper end and swing and rotate with the lower end suspended. During this process, an operator holds a spray gun by hand to apply glaze. Therefore, the quality of the external glazing is affected by the unstable swing amplitude of the electric porcelain rotation, which extremely relies on manual labor. Moreover, changes in the manual glazing angle, the distance between the spray gun and the product, etc. will all affect the glazing quality, and full-automatic glazing by a robot cannot be carried out. Summary of the Invention

[0003] The purpose of the present invention is to provide a pilot positioning rotary workstation that supports the placement of the special-shaped bottom surface of an electric porcelain, which can overcome one or more of the above problems. The electric porcelain blank can have a precise and stable rotation state, and has relatively high requirements in terms of coaxiality and perpendicularity, so as to realize full-automatic glazing by a robot, thereby improving the glazing quality of the external shape of the electric porcelain and reducing the labor intensity of manual work.

[0004] The pilot positioning rotary workstation that supports the placement of the special-shaped bottom surface of an electric porcelain of the present invention is realized as follows: it includes a base with a vertical frame, a rotating table arranged on the base, and a movable frame arranged on the vertical frame and driven by an up-and-down driving power to move up and down. A lower positioning cone is arranged at the rotation center of the rotating table, and more than three flexible clamps are evenly arranged on the rotating table around the lower positioning cone. An upper positioning cone is arranged directly below the movable frame and opposite to the lower positioning cone. Place the electric porcelain blank on the rotating table, so that the bottom conical notch is buckled on the lower positioning cone. At the same time, the flexible clamps lean against the bottom surface of the electric porcelain blank. Several columns on the upper surface of the flexible clamps abut against the bottom surface of the electric porcelain blank, and adaptively move down according to the unevenness of the bottom surface of the electric porcelain blank, so that the tops of all the columns lean against the bottom surface of the electric porcelain blank. Then, drive the fixed rocker arms of the columns of the flexible clamps to fix the positions of all the columns so that they cannot move up and down, and support the electric porcelain blank. Even if the bottom surface of the electric porcelain blank is uneven, the electric porcelain blank can be stably vertically positioned on the rotating table. Then, drive the movable frame to move down by the up-and-down driving power. The upper positioning cone below the movable frame abuts against the conical notch at the top of the electric porcelain blank, so that the electric porcelain blank is fixed at the rotation center of the rotating table, ensuring a fixed distance between the electric porcelain blank and the spray gun, thereby realizing full-automatic glazing by a robot, improving the glazing quality of the external shape of the electric porcelain, and at the same time, reducing the labor intensity of manual work.

[0005] Compared with the prior art, the present invention has the advantages that the porcelain blank can have an accurate and stable rotating state, with high requirements for coaxiality and perpendicularity, so as to realize fully automatic glazing by a robot, thereby improving the glazing quality of the external shape of the electrical porcelain and reducing the labor intensity of workers.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0008] Now, with reference to the drawings and embodiments, the pilot positioning and rotating workstation for supporting the placement of the special-shaped bottom surface of an electrical porcelain according to the present invention will be further described in detail: As Figure 1-2 shown, the pilot positioning and rotating workstation for supporting the placement of the special-shaped bottom surface of an electrical porcelain according to the present invention is realized as follows, including a base 2 with a vertical frame 1, a rotating table 3 arranged on the base 2, and a movable frame 5 arranged on the vertical frame 1 and driven by an up and down driving power 4 (including a lead screw driven by a motor mechanism and a nut fixed on the movable frame 5 driven by the lead screw) to move up and down along the guide rail on the vertical frame 1. A lower positioning cone 6 is arranged at the rotation center of the rotating table 3, and more than three flexible fixtures 7 are evenly arranged on the rotating table 3 around the lower positioning cone 6. An upper positioning cone 8 is arranged directly below the movable frame 5 opposite to the lower positioning cone 6; Preferably, a buffer 9 is arranged on the rotating table 3 below the lower positioning cone 6, which is used for pre-positioning the bottom of the workpiece and can prevent the workpiece from being damaged due to impact during the placement process.

[0009] The rotating table 3 includes a circular tabletop 302 driven by an electric power 301, and the buffer 9 and the flexible fixture 7 are both fixedly connected to the circular tabletop 302.

[0010] Place the porcelain blank on the rotating table 3, so that the conical notch at the center of the bottom of the porcelain blank is buckled on the lower positioning cone 6. At the same time, the flexible fixture 7 leans against the bottom surface of the porcelain blank, and several columns 701 on the upper surface of the flexible fixture 7 abut against the bottom surface of the porcelain blank, and make an adaptive downward movement according to the unevenness of the bottom surface of the porcelain blank, so that the tops of all columns 701 lean against the bottom surface of the porcelain blank. Then drive the column fixing rocker arm 702 of the flexible fixture 7 to fix the positions of all columns 701 so that they cannot move up and down, and support the porcelain blank. Even if the bottom surface of the porcelain blank is uneven, the porcelain blank can be stably vertically positioned on the rotating table 3. Then, drive the movable frame 5 to move down by the up and down driving power 4, and the upper positioning cone 8 under the movable frame 5 abuts against the conical notch at the center of the top of the porcelain blank, so that the porcelain blank is fixed at the rotation center of the rotating table 3, ensuring a fixed distance between the porcelain blank and the spray gun, so as to realize fully automatic glazing by the robot, which not only improves the glazing quality of the porcelain appearance, but also reduces the labor intensity of workers.
