[0002] A fixture is a process device used to quickly fasten the workpiece during processing so that the machine tool, tool, and workpiece maintain the correct relative position. That is to say, tooling fixtures are indispensable parts of mechanical processing. Driven by the development of machine tool technology towards high speed, high efficiency, precision, compound, intelligent, and environmentally friendly, fixture technology is developing towards high precision, high efficiency, modular, combined, universal, and economical directions. Fixtures are also called fixtures. In a broad sense, any device used to quickly, conveniently, and safely install workpieces in any process in the process can be called a fixture. For example, welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures. When processing a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements such as size, geometric shape and relative position accuracy with other surfaces specified in the drawing, the workpiece must be installed (positioned) and clamped (clamped) before processing. However, the special interchangeable tooling for the expansion piston usually uses screws for installation and connection when tightening the expansion piston fixing fixture. Replacement and installation are very inconvenient and not conducive to improving installation efficiency. The improved flip card strip of the utility model is rotatably connected to the adjusting stud, and the height position of the flip card strip can be adjusted by turning and dialing the adjusting knob. The flip card strip can be clamped to the expansion piston fixing fixture, and the flippable flip plug-in column can adjust the plug-in angle. The improvement of the utility model can more conveniently adjust the expansion piston fixing fixture. The installation of the expansion piston fixing fixture is more convenient, thereby improving the practicality of the special interchangeable tooling for the expansion piston. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-5 As shown, a special interchange tool for an expansion piston comprises a quick-change base plate 2 arranged at the upper end position of a quick-change base 1; an expansion piston fixing fixture 3 is arranged at the upper end position of the quick-change base plate 2; a plug-in slot 8 is arranged on the quick-change base plate 2, a flip plug-in column 12 is arranged in the plug-in slot 8, a built-in connecting spring 18 is arranged in the flip plug-in column 12, a metal ball 17 is arranged at the outer position of the built-in connecting spring 18, a mounting clamp main block 11 is arranged on the flip plug-in column 12, a toggle adjustment knob 13 is arranged at the middle position of the mounting clamp main block 11, and the toggle adjustment knob 13 is arranged at the middle position of the mounting clamp main block 11. An adjusting stud 16 is provided at the middle position of the knob 13, and a flip clamping strip 14 is provided at the upper end position of the adjusting stud 16. The flip clamping strip 14 is rotatably connected to the adjusting stud 16. The height position of the flip clamping strip 14 can be adjusted by rotating and toggling the adjusting knob 13. The flip clamping strip 14 can be clamped to the expansion piston fixing fixture 3. The improvement of the utility model can more conveniently adjust the clamping of the expansion piston fixing fixture 3, thereby making it more convenient to install the expansion piston fixing fixture 3, thereby improving the practicality of the special interchangeable tooling for the expansion piston.

[0024] like Figure 4 As shown, expansion strips 15 are provided near both sides of the flip card strip 14, and the expansion strips 15 are installed and connected to the flip card strip 14 by plugging. The expansion strips 15 allow the user to adjust the length of the flip card strip 14 according to actual conditions, thereby making it easier to adjust according to actual conditions.

[0025] like Figure 4 As shown, the toggle adjustment knob 13 is installed and connected to the mounting clamp main block 11 via a rotating shaft, and vertical lines are provided at the outer side of the toggle adjustment knob 13. The vertical lines of the toggle adjustment knob 13 can increase the friction between the toggle adjustment knob 13 and the user's hand, thereby making it easier for the user to operate and rotate it with force.

[0026] like Figure 4As shown, a quick-change substrate locating pin 10 is provided at the middle position between the quick-change substrate 2 and the quick-change base 1, and positioning balls 9 are provided at both sides of the quick-change substrate locating pin 10.

Fixture fixing pins 4 are provided at the two sides of the limit installation groove 5, and the fixture fixing pins 4 are cylindrical pins. A piston locking nut 7 is provided at the side position of the expansion piston fixing fixture 3, and the piston locking nut 7 is installed and connected with the expansion piston fixing fixture 3 by rotation. The expansion piston fixing fixture 3 is fixed to the zero-point positioning replacement plate of the quick-change substrate 2. The expansion piston fixing fixture 3 and the zero-point positioning replacement plate of the quick-change substrate 2 are positioned by pins to achieve the purpose of interchangeability. The inner hole matching the expansion piston shape is processed on the fixture body of the part 3 to make it gap-matched with the expansion piston shape. The quick-change base 1 and the quick-change substrate 2 of this product use pneumatic spherical locks, and the expansion piston fixing fixture 3 and the quick-change substrate 2 replacement plate are both positioned with pins, which avoids the influence of tooling accuracy when replacing the quick-change substrate 2 replacement plate or the expansion piston fixing fixture 3.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
