Description

Technical Field

[0001] This utility model relates to the field of workpiece positioning technology, and in particular to a pilot-type positioning rotary workstation that supports the placement of irregularly shaped bottom surfaces of electrical porcelain. Background Technology

[0002] The glazing process for the porcelain blanks of post insulators is currently mostly done manually. Because the blanks of post insulators are heavy, fragile, and have uneven cross-sections, the porcelain blanks can only be fixed at the top and suspended in the air while being swung and rotated. The glazing is done manually with a handheld spray gun. Therefore, the quality of the glazing is unstable due to the rotation and swing of the porcelain blanks, making it extremely dependent on manual labor. Furthermore, changes in the manual glazing angle and the distance between the spray gun and the product will affect the glazing quality, making fully automated robotic glazing impossible. Summary of the Invention

[0003] The purpose of this utility model is to provide a pilot-type positioning rotary workstation that can overcome one or more of the above-mentioned problems, allowing the ceramic blank to have a precise and stable rotation state, requiring high standards in coaxiality and perpendicularity, so as to enable fully automated robotic glazing, thereby improving the glazing quality of the ceramic blank and reducing the intensity of manual labor.

[0004] The pilot-type positioning rotary workstation supporting the placement of irregularly shaped bottom surfaces of electric porcelain in this utility model is implemented as follows: it includes a base with a vertical frame, a rotating platform set on the base, and a movable frame set on the vertical frame and driven to move up and down by an up-and-down driving force. The rotation center of the rotating platform is provided with a lower positioning cone, and three or more flexible clamps are evenly arranged on the rotating platform around the lower positioning cone. An upper positioning cone is provided under the movable frame directly opposite the lower positioning cone.

[0005] The ceramic blank is placed on the rotating table, with the bottom conical notch engaging the lower positioning cone. Simultaneously, the flexible clamp rests against the bottom surface of the ceramic blank, and several pillars on the upper surface of the flexible clamp press against the bottom surface of the ceramic blank. Depending on the unevenness of the ceramic blank's bottom surface, the clamp is adjusted downwards to ensure that the tops of all pillars are against the bottom surface. Then, the pillar fixing rocker arm of the flexible clamp is driven to fix the position of all pillars, preventing them from moving up or down, thus supporting the ceramic blank. Even if the bottom surface of the ceramic blank is uneven, it can be stably and vertically positioned on the rotating table. Then, the movable frame is lowered by the up-and-down driving force, and the upper positioning cone under the movable frame presses against the conical notch on the top of the ceramic blank, fixing the ceramic blank at the rotation center of the rotating table. This ensures a fixed distance between the ceramic blank and the spray gun, enabling fully automated robotic glazing, improving the glazing quality of the ceramic blank while reducing manual labor intensity.

[0006] Compared with existing technologies, this invention has the advantages of allowing the ceramic blank to have a precise and stable rotation state, requiring high standards in coaxiality and perpendicularity, so as to achieve fully automated robotic glazing, thereby improving the glazing quality of the electric porcelain and reducing the intensity of manual labor.

Detailed Implementation

[0010] The pilot-type positioning rotary workstation supporting the placement of irregularly shaped bottom surfaces of electrical porcelain, as described in the accompanying drawings and embodiments, will now be described in further detail:

[0011] like Figure 1-2 As shown, the pilot-type positioning rotary workstation supporting the placement of irregularly shaped bottom surfaces of electric porcelain of this utility model is implemented as follows: it includes a base 2 with a vertical frame 1, a rotating platform 3 set on the base 2, and a movable frame 5 set on the vertical frame 1 and driven by an up-and-down driving force 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. The rotation center of the rotating platform 3 is provided with a lower positioning cone 6, and three or more flexible clamps 7 are evenly arranged on the rotating platform 3 around the lower positioning cone 6. An upper positioning cone 8 is provided directly below the movable frame 5 facing the lower positioning cone 6.

[0012] Preferably, a buffer 9 is provided on the rotating platform 3 below the lower positioning cone 6, which serves two purposes: firstly, to pre-position the bottom of the workpiece, and secondly, to prevent damage to the workpiece due to impact during placement.

[0013] The rotating table 3 includes a circular table 302 driven by an electric power source 301, and a buffer 9 and a flexible clamp 7 are fixedly connected to the circular table 302.

[0014] The porcelain blank is placed on the rotating table 3, so that the conical notch at the center of the bottom of the porcelain blank is engaged with the lower positioning cone 6. At the same time, the flexible clamp 7 rests against the bottom surface of the porcelain blank, and several pillars 701 on the upper surface of the flexible clamp 7 press against the bottom surface of the porcelain blank. Depending on the unevenness of the bottom surface of the porcelain blank, the clamp 7 is adjusted downwards so that the tops of all the pillars 701 are against the bottom surface of the porcelain blank. Then, the pillar fixing rocker arm 702 of the flexible clamp 7 is driven to fix the position of all the pillars 701, preventing them from moving up or down. The rotating platform 3 supports the ceramic blank, ensuring that even if the bottom surface of the ceramic blank is uneven, it can be stably and vertically positioned on the rotating platform 3. Then, the moving frame 5 is moved down by the up and down driving force 4. The upper positioning cone 8 under the moving frame 5 presses against the conical notch at the center of the top of the ceramic blank, fixing the ceramic blank at the rotation center of the rotating platform 3. This ensures that the distance between the ceramic blank and the spray gun is fixed, thereby realizing fully automatic glazing by the robot, which not only improves the glazing quality of the ceramic blank but also reduces the intensity of manual labor.
