[0032] Working principle: before using the clamping and positioning fixture for mechanical engineering to clamp and position the workpiece, firstly, it is necessary to adjust the height of the mounting plate 302 and the cleaning brush 303 according to the size of the workpiece. When adjusting, it is necessary to push the clamping shaft 305 to retract the clamping shaft 305 into the mounting sleeve 301, adjust the mounting plate 302 to a suitable height, and then move the clamping shaft 305 into the corresponding clamping hole 306 to fix the position of the mounting plate 302 and the cleaning brush 303. Then, according to the size of the workpiece, the two threaded rods 402 are rotated, and the two threaded rods 402 will respectively drive the two adjustment plates 401 to move, so that the two adjustment plates 401 can be fixed in a suitable position. When the clamping and positioning fixture for mechanical engineering is used to clamp and position the workpiece, the two second cylinders 601 need to be started respectively first, and the two second cylinders 601 will respectively drive the two driving plates 5 to move, and the two driving plates 5 will respectively drive the two clamping plates 10 to move through the two mounting shafts 801, and the two clamping plates 10 will respectively abut on both sides of the workpiece to clamp its position. When the two clamping plates 10 abut on both sides of the workpiece, the multiple fixing rods 901 will be attached to the outside of different shapes under the action of the multiple transmission plates 904, so that the workpieces of different shapes can be stably clamped; When the angle of the workpiece needs to be adjusted, the third cylinder 804 needs to be started first. The output end of the third cylinder 804 will drive the rack plate 803 to move, and the rack plate 803 will drive the mounting wheel 802 on the outer side of the mounting shaft 801 on one side to rotate, so that the angle of the workpiece can be adjusted, which not only saves time and manpower for re-adjusting the angle of the workpiece, but also avoids the error caused by re-adjusting the angle of the workpiece, thereby ensuring the accuracy of workpiece processing; When processing the workpiece, it is necessary to start the first cylinder 304, and the output end of the first cylinder 304 will drive the contact plate 2 to move toward the side of the mounting seat 1, and the contact plate 2 will simultaneously drive the two adjustment plates 401 to move, so that the two adjustment plates 401 are respectively moved to the side of the two locking plates 701, so that the positions of the driving plate 5 and the clamping plate 10 on both sides can be locked to prevent their positions from shifting during the workpiece processing, thereby ensuring the quality of tool processing; When the workpiece is processed, the first cylinder 304 is started to drive the resistance plate 2 to continue moving. The resistance plate 2 will drive the mounting sleeve 301 and the mounting plate 302 on the upper side to move, and the mounting plate 302 will drive the cleaning brush 303 to move, so as to clean the waste chips generated by the processing on the upper end of the workpiece. This not only significantly improves the cleanliness of the working environment, reduces the potential impact of waste chips on subsequent processing or workpiece quality, but also greatly saves the time and labor cost of manual cleaning. At the same time, when the resistance plate 2 moves, it will also push the processed workpiece to one side of the clamping and positioning tooling, avoiding the safety hazards and inefficiency problems that may be caused by manual intervention, thereby making the use experience of the clamping and positioning tooling for mechanical engineering more convenient and safe, and the practicality has been significantly improved.
