[0052] See also Figures 1 to 8 The utility model provides an intelligent manufacturing clamping device that can be used for a disc cam 1, including a box-shaped clamping device 2, a quick-change tray 3 and a clamping mechanism 5. The box-shaped clamping device 2 includes a box frame 21, a positioning clamping mechanism 22 and a positioning RFID chip 23. The positioning clamping mechanism 22 is arranged on the box frame 21, and a corresponding positioning RFID chip 23 is arranged next to the positioning clamping mechanism 22. The positioning RFID chip 23 is used to store position information that can locate the clamping mechanism 22 on the box frame 21. The quick-change tray 3 can be detachably mounted on the positioning clamping mechanism 22. A positioning base surface 31 is provided, and an RFID mechanism 4 with reading, writing and information storage functions is also installed on the quick-change tray 3, that is, the RFID mechanism 4 has an RFID chip and an RFID reader / writer. When the quick-change tray 3 is installed on the positioning clamping mechanism 22, the RFID mechanism 4 can read the positioning RFID chip 23 corresponding to the positioning clamping mechanism 22; the clamp mechanism 5 can clamp the disc cam 1, and the clamp mechanism 5 is provided with a clamp chassis 51 detachably installed on the quick-change tray 3, and the bottom of the clamp chassis 51 is provided with a clamp positioning surface 511 that fits the positioning base surface 31. Among them, the RFID chip 23 and the RFID mechanism 4 are both mature products that use the existing RFID (radio frequency identification) technology.

[0053] The basic working principle of the intelligent manufacturing clamping equipment involved in the utility model is: the box-shaped clamping device 2 can be set to multiple, the box-shaped clamping device 2 is set on the processing machine tool for processing, and the box-shaped clamping device 2 is set on the part detection device for detection of parts after processing. Before processing, the cam blank 6 for manufacturing the disc cam 1 is clamped in the clamp mechanism 5, and then the clamp chassis 51 of the clamp mechanism 5 is fixedly connected to a quick-change pallet 3, and the clamp positioning surface 511 at the bottom of the clamp chassis 51 is in contact with the positioning base surface 31 to ensure that the two are stably connected and positioned, and the part code and part sequence of the disc cam 1 to be processed and other processing information related to part processing are entered into the RFID mechanism 4 on the quick-change pallet 3, and the size information and detection program of the disc cam 1 can also be entered; the quick-change pallet 3 is installed on the positioning clamping mechanism 22 of a box-shaped clamping device 2 to complete the positioning clamping. At this time, the RFID mechanism 4 on the quick-change pallet 3 can just read the position information stored in the positioning RFID chip 23 corresponding to the positioning clamping mechanism 22, and write it into the RFID mechanism 4, wherein the position information of the clamped cam blank 6 on the box frame 21 can be converted according to the position information of the positioning clamping mechanism 22 on the box frame 21 stored in the positioning RFID chip 23. After the clamping is completed, the box-shaped clamping device 2 is installed on the machine tool. When processing, the machine tool only needs to read the processing information and position information in the RFID mechanism 4 on the quick-change tray 3. According to the position information and the position of the box frame 21 on the machine tool, the position of the cam blank 6 to be processed in the machine tool can be obtained, which is convenient for processing. After the processing of the disc cam 1 is completed, the box-shaped clamping device 2 can be removed from the machine tool to reduce the occupation of the machine tool. Then the quick-change tray 3 is removed from the box-shaped clamping device 2, and the clamping mechanism 5 and the disc cam 1 are transferred to the detection device together, and the quick-change tray 3 is installed on the positioning clamping mechanism 22 of the box-shaped clamping device 2 at the detection device. The same principle as the processing, the RFID mechanism 4 can also complete the position information reading of the positioning RFID chip 23, so as to obtain the position of the disc cam 1 at the detection station, and when testing, the size information and detection program of the disc cam 1 in the RFID mechanism 4 can be read, and the parts can be directly inspected without correction, so as to facilitate the detection of the processing quality of the disc cam 1.

[0054] In this intelligent manufacturing clamping equipment, the clamping mechanism 5 can adopt a universal clamp to clamp the cam blank 6 of the disc cam 1 of different models and sizes. The box-shaped clamping device 2 can clamp the disc cam 1 of different models and sizes for processing and testing, which is particularly suitable for discrete manufacturing of multiple varieties and small batches; the clamping and disassembly of the disc cam 1 parts are all installed outside the machine tool, which does not occupy the machine tool time and improves the effective utilization rate of the machine tool; from processing to testing, the clamping and correction of parts can be reduced, thereby improving the overall work efficiency of processing and testing.

Preferably, a number is provided on the box frame 21, and the positioning clamping mechanism 22 thereon is numbered. The signal stored in the positioning RFID chip 23 includes the number of the positioning clamping mechanism 22 to determine the position of the positioning clamping mechanism 22.
