[0019] Any process or method description in a flowchart or otherwise described herein may be understood to represent a module, segment or portion of code comprising one or more executable instructions for implementing the steps of a specific logical function or process, and the scope of the preferred embodiments of the present invention includes alternative implementations in which functions may be performed out of the order shown or discussed, including performing functions in a substantially simultaneous manner or in the reverse order depending on the functions involved, which should be understood by those skilled in the art to which the embodiments of the present invention pertain.

[0020] like Figures 1 to 4 As shown, the utility model provides a fixture quick-change connection device for a positioner, which is used for the quick-change connection of a fixture plate 1, including a flange 2 and a connecting plate 3, wherein a plurality of connecting holes 4 are distributed on the flange 2, and the connecting plate 3 is fixedly connected to the flange 2 through some of the connecting holes 4; a guide block 5 is fixedly provided on the connecting plate 3, and a guide groove matching the guide block 5 is provided on the fixture plate 1; the fixture plate 1 and the connecting plate 3 are quickly connected by a positioning mechanism, a pre-tightening mechanism and a fixing mechanism.

[0021] This fixture quick-change connection device allows the fixture to be quickly installed on the positioner, achieving rapid positioning, clamping, and fixation of the fixture plate 1 and the flange 2 on the positioner. The multiple connection holes 4 distributed on the flange 2 provide different installation positions for the connecting plate 3 to accommodate different fixture installation sizes. During operation, the connecting plate 3 is first installed on the flange 2 at the corresponding position according to the different fixture specifications and models, completing the positioning and fixation of the connecting plate 3 and the flange 2.

[0022] Then install the fixture plate 1 and the connecting plate 3. The connecting plate 3 plays the role of transition connection. During the installation process of the fixture plate 1 and the connecting plate 3, the guide block 5 plays the role of preliminary guidance. By inserting the guide block 5 into the guide groove, this preliminary positioning can guide the preliminary positioning connection of the fixture plate 1 and the connecting plate 3. After completing the preliminary positioning, the final positioning and fixed connection installation of the fixture plate 1 and the connecting plate 3 are completed through the positioning mechanism, pre-tightening mechanism and fixing mechanism.

[0023] The positioning mechanism includes a positioning pin 6 installed on the fixture plate 1 and a positioning sleeve 7 installed on the connecting plate 3. The fixture plate 1 is provided with a pin positioning hole 8, and the positioning pin 6 is inserted into the pin positioning hole 8; the connecting plate 3 is provided with a sleeve positioning hole 9, and the positioning sleeve 7 is inserted into the sleeve positioning hole 9; the bottom of the positioning pin 6 is inserted into the inner hole of the positioning sleeve 7.

[0024] The positioning mechanism realizes the precise positioning of the fixture plate 1 and the connecting plate 3 after the guide block 5 and the guide groove complete the initial positioning. During positioning, the positioning pin 6 is inserted into the inner hole of the positioning sleeve 7 to complete the positioning connection. The positioning method using the positioning pin 6 and the positioning sleeve 7 has a higher positioning accuracy, and when the connection method needs to be released, the release of the positioning connection is also convenient and quick.

[0025] A first set screw 10 is installed on the fixture plate 1, and the first set screw 10 fixes the positioning pin 6 on the fixture plate 1; a second set screw 11 is installed on the connecting plate 3, and the second set screw 11 fixes the positioning sleeve 7 on the connecting plate 3.

[0026] The first set screw 10 can tightly install the positioning pin 6 on the fixture plate 1, and the second set screw 11 can tightly install the positioning sleeve 7 on the connecting plate 3. The use of the first set screw 10 and the second set screw 11 can improve the reliability of the installation of the positioning mechanism and avoid the positioning pin 6 and the positioning sleeve 7 from moving in series during operation.

[0027] The pre-tightening mechanism includes a pivot bolt 12 installed on the connecting plate 3 and rotatably installed by a turn pin. A locking groove 13 is provided on the clamp plate 1 at a position corresponding to the pivot bolt 12. The locking groove 13 is an open groove 14. The pivot bolt 12 is inserted into the open groove 14. A pivot nut 15 is installed on the pivot bolt 12, and the pivot nut 15 is locked on the clamp plate 1.

[0028] The pre-tightening device is used to clamp and fix the connecting plate 3 and the clamp plate 1 after the positioning mechanism completes the precise positioning. The swing bolt 12 can be rotated around the turn pin so that it can be installed into the locking groove 13 or removed from the locking groove 13. When the positioning is completed, the swing bolt 12 is rotated to fit into the locking groove 13, and then the swing nut 15 is screwed into and installed on the swing bolt 12, so that the locking connection between the clamp plate 1 and the connecting plate 3 can be completed; when the connection needs to be removed, it is also necessary to unscrew the release swing nut 15. After the swing nut 15 is released from the swing bolt 12, the swing bolt 12 can be rotated and removed from the locking groove 13, so that the fixed pre-tightening of the pre-tightening device can be released.

[0029] The fixing mechanism includes mounting bolts 16, which securely connect the fixture plate 1 and the connecting plate 3. After the pre-tightening is completed, the mounting bolts 16 are tightened to complete the connection and fixation of the connecting plate 3 and the fixture plate 1, which is convenient and quick. When the fixture plate 1 needs to be removed, the mounting bolts 16 are similarly loosened to complete the connection of the fixing mechanism.
