[0002] With the continuous development of mechanical processing technology, interchangeable fixtures emerge as the times require. An interchangeable fixture is usually composed of a positioning mechanism and multiple interchangeable work platforms. When one of the interchangeable work platforms is clamped with a workpiece for processing in a processing center, the workpiece on another interchangeable work platform can be clamped. After the processing center finishes processing, the interchangeable work platform clamped with the workpiece to be processed is used to replace the interchangeable work platform clamped with the processed workpiece, so that the workpiece can be quickly replaced. In the traditional technology, the positioning mechanism for positioning the interchangeable work platform generally includes multiple air cylinders, which rely on the air cylinders to clamp and position the interchangeable work platform. However, the air cylinders are prone to damage during long-term use and need to be regularly maintained by personnel. Moreover, the pressure of the air cylinders is limited, and the work platform is prone to being pulled up during high-speed processing of the processing machine, thereby causing abnormal processing.

The support protrusion 11 is located away from the protruding portion 2223 and is spaced apart from the protruding portion 2223. One end of the elastic piece 223 away from the protruding portion 2223 abuts against the support protrusion 11. The elastic piece 223 is used to push the protruding portion 2223 to move towards the driving assembly 21, thereby driving the sliding piece 222 and the plurality of positioning pieces 221 to move towards the driving assembly 21, so that the positioning pieces 221 move out of the through hole 32 and thereby loosen the interchangeable board 30.

[0031] The sliding portion 2221 can be a block structure extending along the movement direction of the sliding portion 2221. The connecting portion 2222 can be a strip structure extending along a direction perpendicular to the movement direction of the sliding portion 2221.

Two elastic pieces 223 are symmetrically arranged in each positioning assembly 22. The support protrusion 11 is provided with four support protrusions 11. Each support protrusion 11 is correspondingly arranged with one protruding portion 2223. The two ends of each elastic piece 223 abut against the corresponding protruding portion 2223 and the support protrusion 11.

[0032] When the interchangeable board 30 needs to be positioned, the driving assembly 21 pushes the two positioning assemblies 22 away from each other. In the sliding process, the sliding piece 222 in each positioning assembly 22 compresses the elastic piece 223 through the protruding portion 2223, without affecting the sliding piece 222 driving the positioning pieces 221 to be inserted into the through hole 32 of the locking block 31. When the interchangeable board 30 needs to be loosened, the elastic piece 223 pushes the protruding portion 2223 to move towards the driving assembly 21, thereby driving the sliding piece 222 and the plurality of positioning pieces 221 to move towards the driving assembly 21, so that the positioning pieces 221 move out of the through hole 32 and thereby loosen the interchangeable board 30.

In this way, the positioning block 224 can support the sliding part 2221, the sliding part 2221 can slide along the positioning block 224, and the movement direction of the sliding part 2221 can be limited. In this embodiment, the cross section of the strip-shaped hole 2224 is substantially T-shaped, the cross section of the positioning block 224 is substantially T-shaped, and the positioning block 224 supports the sliding part 2221 through the step.

The positioning hole 12 can be provided with four, six, eight or the like, and the specific number and position of the positioning hole 12 correspond to the two groups of locking blocks 31 one by one. When the interchangeable plate 30 is placed on the support plate 10, each locking block 31 is inserted into the corresponding positioning hole 12, and the positioning hole 12 can cooperate with the locking block 31 to position the interchangeable plate 30.

By arranging the sliding hole 13, the positioning piece 221 can be slidingly connected with the support plate 10, and at the same time, the positioning piece 221 is limited. It can be understood that when the locking block 31 is inserted into the corresponding positioning hole 12, the through hole 32 in the locking block 31 is in communication with the sliding hole 13, so that the positioning piece 221 can be inserted into the through hole 32. The sliding hole 13 can pass through the positioning hole 12, so that the end of the positioning piece 221 away from the sliding part 2221 can move into the sliding hole 13 on the side of the positioning hole 12 away from the sliding part 2221 after passing through the through hole 32, so as to position the end of the positioning piece 221 in the direction perpendicular to the plane of the support plate 10. Thus, the stability of the interchangeable plate 30 during processing can be further improved.

When the sliding part 2221 drives the connecting part 2222 to move close to or away from the driving assembly 21, the connecting protrusion 2225 on the connecting part 2222 moves in the limiting hole 14, and when the connecting protrusion 2225 abuts against the side wall of the limiting hole 14, the connecting protrusion 2225 stops moving, that is, the movement distance of the connecting protrusion 2225 can be limited by the limiting hole 14, so that the connecting protrusion 2225 can avoid driving the positioning piece 221 to slide out of the sliding hole 13, thereby affecting the installation and disassembly of the interchangeable plate 30.

The number of limiting grooves 15 can be four, six, eight, etc., the number and position of the limiting grooves 15 correspond one by one to the limiting holes 14, and it can be understood that in the actual production and processing process, the sliding hole 13 and the limiting groove 15 can be processed at one time to make the limiting groove 15 and the sliding hole 13 coaxial and have the same radius. By arranging the limiting groove 15, the end of the positioning piece 221 close to the driving assembly 21 can be accommodated when the positioning piece 221 moves towards the driving assembly 21, so as to guide the positioning piece 221.
