Description

Universal mounting frame for positioner clamp Technical field: The utility model relates to a universal mounting frame for a positioner clamp. The background technology is as follows: When some complex workpieces are welded, the workpieces are required to be installed on a position changing machine through a tool, so that the tool and the workpieces on the tool are driven to rotate through the position changing machine, and at present, the tool is usually custom-designed according to each product and mainly comprises a base, a clamp bottom plate and a clamp, wherein the base is installed in a matched mode with the position changing machine, the clamp bottom plate is fixedly installed on the base, and the clamp is fixedly installed on the clamp bottom plate and used for clamping different positions of the workpieces. Because the workpieces in the welding process are different, the workpieces are large and small, the size of the clamp bottom plate is also large and small, but the size of the base in each tool is approximately the same, and the base is fixedly arranged on each tool at present, so that the tool is high in manufacturing cost and long in manufacturing time. The invention comprises the following steps: In view of the problems in the prior art, the utility model aims to provide a universal mounting frame for a positioner clamp, which is reasonable in design, does not need to repeatedly manufacture the frame, and is beneficial to improving the manufacturing efficiency of the tool and reducing the cost. The utility model is realized by adopting the following scheme, The universal mounting frame for the positioner clamp is characterized by comprising a rectangular frame and connecting seats arranged at two sides of the rectangular frame and used for being connected with the positioner, wherein positioning pin holes and threaded holes are formed in four side bars of the rectangular frame in an equidistant and staggered mode, a bushing with a positioning hole in the center is arranged in the positioning pin holes, the upper end face of the bushing is lower than the upper surface of the rectangular frame, and the upper surface of the rectangular frame is used for mounting a clamp bottom plate. Preferably, the distance between the positioning pin hole and the threaded hole is 100mm, and the distance between the adjacent positioning pin hole and the adjacent threaded hole is 200mm. Preferably, the length and width of the rectangular frame are 1900mm and 700mm, respectively. Preferably, the distance between the positioning pin holes or the threaded holes on the two opposite side bars of the rectangular frame is 640mm. Preferably, the middle part of the rectangular frame is provided with an intermediate support plate with the upper surfaces being flush with each other, and the intermediate support plate is provided with two rows of equally-spaced staggered positioning pin holes and threaded holes, and the spacing between the two rows of positioning pin holes and the threaded holes is 100mm. Preferably, the positioning pin hole is a stepped hole, the bushing is a stepped shaft which is installed in the positioning pin hole in an interference fit manner, after the clamp bottom plate is installed on the upper surface of the rectangular frame, the positioning hole on the clamp bottom plate is opposite to the positioning hole on the bushing and is inserted into the positioning pin to be positioned, and the positioning pin is connected with the threaded hole through a through hole on the bottom plate by a bolt. The utility model relates to a method for using a universal mounting frame of a fixture of a positioner, which comprises the steps of connecting a connecting seat with the positioner when a fixture is mounted on the positioner, ensuring that the rectangular frame is in a horizontal station, superposing a fixture bottom plate on the upper surface of the rectangular frame, enabling a positioning hole on the fixture bottom plate to be opposite to the positioning hole in the rectangular frame, inserting a positioning pin into the positioning hole for positioning, and connecting the positioning pin with a threaded hole through a through hole on the bottom plate, wherein the fixture is mounted. The universal mounting frame for the positioner clamp has the advantages that: 1. The rectangular frame is arranged on the position changing machine, and the clamp is not required to be disassembled when being switched, so that the switching efficiency is improved; 2.
