Description

Technical fields:

[0001] This utility model relates to a universal mounting frame for positioner fixtures. Background technology:

[0002] When welding some complex workpieces, the workpiece needs to be mounted on a positioner using a fixture so that the positioner can drive the fixture and the workpiece on it to rotate. Currently, the fixture is usually customized according to each product. It mainly includes a base that is installed with the positioner, a fixture base plate that is fixedly installed on the base, and a fixture that is fixedly installed on the fixture base plate to hold the workpiece at different positions.

[0003] Because the workpieces in the welding process are different and vary in size, the size of the fixture base plate also varies. However, the size of the base in each tooling is roughly the same. Currently, each tooling has a fixed base, which results in high tooling manufacturing costs and long manufacturing time. Summary of the Invention:

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to propose a universal mounting frame for positioner fixtures. This universal mounting frame for positioner fixtures is reasonably designed, eliminates the need for repeated frame manufacturing, and helps to improve tooling manufacturing efficiency and reduce costs.

[0005] This utility model is implemented using the following solution.

[0006] The present invention relates to a universal mounting frame for a positioner fixture, characterized in that: it includes a rectangular frame and connecting seats on both sides of the rectangular frame for connecting with the positioner; the four side strips of the rectangular frame are provided with locating pin holes and threaded holes at equal intervals; a bushing with a central locating hole is installed in the locating pin hole; 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 to install the fixture base plate.

[0007] Preferably, the distance between the locating pin hole and the threaded hole is 100mm, and the distance between adjacent locating pin holes and adjacent threaded holes is 200mm.

[0008] Preferably, the length and width of the rectangular frame are 1900mm and 700mm, respectively.

[0009] Preferably, the spacing between the locating pin holes or threaded holes on the two opposite side strips of the rectangular frame is 640mm.

[0010] Preferably, a middle support plate with its upper surface flush with each other is installed in the middle of the rectangular frame. The middle support plate is provided with two rows of equidistant staggered positioning pin holes and threaded holes, with the spacing between the two rows of positioning pin holes and threaded holes being 100mm.

[0011] Preferably, the aforementioned positioning pin hole is a stepped hole, and the bushing is an interference fit stepped shaft installed in the positioning pin hole. After the fixture base plate is installed on the upper surface of the rectangular frame, the positioning hole on the fixture base plate is aligned with the positioning hole on the bushing and the positioning pin is inserted for positioning, and the fixture base plate is connected by bolts passing through the through hole and threaded hole on the base plate.

[0012] The method of using the universal mounting frame for positioner fixtures of this utility model is as follows: When installing the fixture on the positioner, connect the connecting seat to the positioner, ensuring that the rectangular frame is in a horizontal position. Then, place the fixture base plate on the upper surface of the rectangular frame, aligning the positioning holes on the fixture base plate with the positioning holes in the rectangular frame. Insert positioning pins into the positioning holes for positioning, and connect the fixture by passing bolts through the through holes and threaded holes on the base plate. This completes the installation of the fixture. When it is necessary to replace the fixture with one for another workpiece, simply remove the bolts and positioning pins to remove the old fixture base plate (including the fixture on the fixture base plate). Then, replace it with a new fixture base plate (including the fixture on the fixture base plate), align it with the positioning holes, insert positioning pins into the positioning holes for positioning, and connect the fixture by passing bolts through the through holes and threaded holes on the base plate. This completes the installation of the new fixture.

[0013] Advantages of this utility model of universal mounting frame for positioner fixtures:

[0014] 1. The rectangular frame is installed on the positioner, and it does not need to be disassembled when switching fixtures, which improves the switching efficiency;

[0015] 2. When a new fixture needs to be made to process a new workpiece, there is no need to repeatedly make a rectangular frame, which reduces development costs;

[0016] 3. The rectangular frame is suitable for a wide range of fixture sizes, thus expanding its applicability. Attached image description:
