The positioning and locking device 30 includes upper and lower positioning parts 32 and 34. When the upper positioning part 32 is fastened to the lower positioning part 34, the A certain air pressure is formed in the air pipe 90 , and the pressure sensor 50 senses the air pressure and sends a signal to the electric control box 40 of the machine tool. The quick-change table body 10 is used to carry the workpiece 100 to be processed, and the air pipe 90 between the solenoid valve 80 and the positioning and locking device 30 is connected to the pressure sensor 50 . the

The positioning and locking device 30 also includes: a locking pull pin 36 installed on the upper positioning member 32 and a locking claw 38 installed on the lower positioning member 34, and the locking pull pin 36 is engaged and locked on the Lock the claw 38 , and then lock the upper positioning member 32 to the lower positioning member 34 . The air pipe 90 is connected to the lower end of the lower positioning member 34 and communicates with the locking claw 38 . the

The upper end of the lower positioning member 34 is tapered, and the top of the lower positioning member 34 forms a horizontal lower tapered surface 342. The lower end of the upper positioning member 32 forms a groove 322 corresponding to the lower positioning member 34, and the groove 322 is fastened. On the upper end of the lower positioning member 34 , the bottom of the groove 322 is configured as a horizontal upper tapered surface 324 corresponding to the lower tapered surface 342 . the

The upper positioning part 32 is connected to the quick-change workbench body 10, the lower positioning part 34 is connected to the machine tool base 20, the locking pull pin 36 is used for positioning the quick-change workbench body 10, and the locking pull claw 38 is used for Then lock the pull pin 36 so that the quick-change table body 10 is positioned and locked on the machine tool base 20 . When the quick-change workbench body 10 is locked on the machine tool base 20, there is a certain air pressure in the air pipe 90, and the pressure sensor senses 50 of the air pressure and sends a signal to the machine tool electric control box 40, and the machine tool electric control box 40 When the pressure sensor 50 detects that the air pressure in the air pipe 90 does not reach the set value, an alarm signal is sent and displayed on the machine tool operation panel 60. the

Wherein, the electric control box 40 of the machine tool controls the closing or conducting of the solenoid valve 80, and the air source 12 may be a cylinder filled with compressed air. When the quick-change workbench 10 is about to be in place, the compressed air is introduced into the positioning and locking device 30 through the air pipe 90, and then the upper and lower tapered surfaces 324, 342 are closed to blow away foreign matter in the gap. the

The specific working principle is as follows: when the quick-change workbench with locking detection mechanism of the utility model is operated, the workpiece 100 to be processed is clamped on the quick-change workbench body 10, and the external mechanical arm puts the quick-change workbench body 10 on the machine tool pedestal 20, when approaching the final position, the raised part 14 on the quick-change table body 10 contacts the contact sensor 70, the contact sensor 70 is triggered to work, and the signal is transmitted to the machine tool electric control box 40, and the machine tool electric control box 40 sends out Command to open the solenoid valve 80, import the compressed air from the air source 12, the compressed air is blown out from the lower cones 342 of the four positioning and locking devices 30 through the air pipe 90, and combined with the upper and lower cones 324, 342 after being reflected by the upper cone 324 If there are foreign objects such as chips between the joint surfaces, the foreign objects will be blown away (the existence of foreign objects will lead to a decrease in positioning accuracy and unreliable locking). After the upper and lower tapered surfaces 324, 342 are closed, the gas in the air pipe 90 is sealed in the air pipe closed circuit to form a pressure. The pressure sensor 50 senses the gas pressure and sends an induction signal to the machine tool electric control box 40, and sends an instruction to pass through the locking claw. 38 lock the locking pull pin 36, and then lock the quick-change workbench body 10. If there is foreign matter between the upper and lower cone surfaces 324, 342 and the gap is formed between the upper and lower cone surfaces 324, 342, part of the compressed air will leak out, the gas pressure in the air pipe circuit will not reach the set value, and the machine tool electric control box 40 An alarm signal is sent and displayed on the operation panel 60 . At this time, the quick-change workbench body 10 must be operated to loosen, the foreign matter in the positioning locking device 30 must be manually removed, and then the quick-change workbench body 10 must be reinstalled. After the foreign matter is completely removed, the gas pressure reaches the set value, and the electric control box 40 of the machine tool sends a safety signal, indicating that the locking is normal. During this process, when the quick-change table body 10 is moved away, the protrusion 14 and the contact sensor 70 are disengaged, and the machine tool electric control box 40 controls the solenoid valve 80 to close, cutting off the blowing of compressed air. the

To sum up, the utility model provides a quick-change workbench with a locking detection mechanism. Compressed air is introduced through the air pipe, which can effectively and clearly locate the cuttings and foreign objects on the locking device, and a pressure sensor is installed on the air pipe to sense the air pipe.
