[0023] Reference Figure 7 、 10 , Any two adjacent tool holders 4 are mounted with oil distribution cavities 16, which have the same shape and structure as the oil cavity 11, and an oil pump is installed inside the oil distribution cavity 16. The oil pump is fixedly connected with a flow distribution valve 161, which has high-precision flow regulation and distribution functions. According to the remote control end setting, the flow distribution ratio of the lubricating oil in different passages can be accurately controlled. One end of the oil distribution cavity 16 is fixedly connected with a branch pipe 17 through a rotary joint. The branch pipe 17 is communicated with one passage of the flow distribution valve 161.

The connecting plate 28 is fixedly connected with a detection piece 29 at the end of the horizontal plate away from the vertical plate. The detection piece 29 has an arc structure. A plurality of oil outlet holes are uniformly arranged on the concave surface of the detection piece 29. Through the pipeline switching of the flow distribution valve 161, when the oil supply to the detection piece 29 is switched, the remote control end will automatically activate the electromagnetic control valve corresponding to the oil distribution cavity 16 of the current tool holder 4 to be matched with the tool changing mechanism according to the position information of the tool holder 4 fed back by the positioning system, so that the branch pipe 17 is communicated with the collecting pipeline. The lubricating oil enters the detection piece 29 in sequence through the branch pipe 17, the collecting pipeline, the main connecting pipe and the connecting hole 281. The electromagnetic control valve corresponding to the oil distribution cavity 16 not participating in the oil supply is kept closed to avoid the interference of the backflow of the lubricating oil, so as to realize the oil injection switching between the detection piece 29 and the oil distribution cavity injection hole 162. Through the extension of the detection piece 29 driven by the second air cylinder 27 and the oil ejection of the oil outlet holes of the detection piece 29, the cooling effect of the changed tool is realized, so that the tool operated at high speed is quickly cooled, preventing the tool in high temperature state from entering the tool magazine and causing damage to the tool magazine.

[0024] In the embodiment, when the tool on the numerical control machine tool needs to be replaced, the first cylinder 23 drives the tool changer 25 to extend, and drives the slider 22 to drive the tool changer 25 to move horizontally through the hydraulic drive 18 until the jaw 251 completes the disassembly of the tool on the numerical control machine tool, and the driving part 7 drives the chain plate 3 to rotate, so that the tool holder 4 to be used falls into the other jaw 251 of the tool changer 25, and at the same time, the oil cavity 11 is opened, and the chain plate 3 is lubricated by spraying lubricating oil through the spray hole 14, and the gear mechanism starts to drive the tool changer 25 to flip, so that the replaced tool falls into the tool holder 4, and the tool to be used is installed on the numerical control machine tool for continuous operation.

[0025] Embodiment two Based on the basis of embodiment one, the bracket 2 is provided with a position sensor, and the tool holder 4 is provided with a positioning sensor, and the position sensor and the positioning sensor are integrated into the positioning system, so that the positioning system can accurately position each tool holder 4 on the bracket 2, and ensure that each tool holder 4 is accurately positioned during each tool changing operation. When the positioning system feedbacks that any tool holder 4 is not in position, it indicates that the chain plate 3 is stuck, causing the position of the tool holder 4 to deviate. The normal oil injection amount of the oil cavity 11 is set to Q1, and the oil injection control valve increases the oil output to Q2 when the chain plate 3 is stuck, and the driving part 7 adjusts the chain plate 3 until the position sensor feedbacks that the current tool holder 4 is accurately positioned.

[0026] Further, in order to prevent the tool magazine from frequently being out of position, the tool magazine is controlled by a remote control terminal. After N1 times of tool changing operation, the driving part 7 drives the chain plate 3 to move and perform self-lubrication. Specifically, during tool changing operation, the driving part 7 controls the moving speed of the chain plate to be v, and after n times of tool changing, the self-lubrication operation is started, and the driving part 7 controls the chain plate 3 to rotate at a speed of v / 2 for one cycle, so that the chain plate 3 is sufficiently lubricated.

[0027] Further, when the sticking phenomenon occurs continuously for N2 times, the self-lubrication operation is also started, and after the chain plate is rotated for one cycle, the driving part 7 adjusts the chain plate 3 to accurately position the tool holder 4.

[0028] Through the above embodiments, the position sensor in the bracket and the positioning sensor in the tool holder are integrated into the positioning system, the tool holder is accurately positioned, the oil injection amount of the oil cavity is automatically increased when the position deviation is detected, and the chain plate is adjusted until it is in position. At the same time, the chain plate is started to be self-lubricated at a low speed by setting the number of tool changing times by the remote control terminal, and the lubrication and adjustment are also started when the sticking phenomenon occurs continuously, which effectively improves the positioning accuracy and reliability of tool changing, reduces manual maintenance, reduces lubricating oil consumption, prolongs the fault-free operation time of the equipment, and ensures the efficient and stable operation of the tool magazine.

[0029] Embodiment three Based on the basis of embodiments one and two, in order to prevent the disassembled tool on the numerical control machine tool still exists residual heat, directly into the tool magazine tool magazine produces irreversible damage, such as Figure 11 As shown in the concave surface of the detection piece 29 is integrated with a temperature sensor, and a telescopic spring is additionally provided at the connection between the horizontal plate and the vertical plate of the connecting plate 28, and a pressure sensor is built-in in the telescopic spring, so as to feedback the elastic extension and contraction amount thereof, wherein the temperature sensor and the pressure sensor are both connected with the remote control end signal.

[0030] When changing the tool, the tool changer 25 extends and moves a distance towards the tool of the numerical control machine tool, the second cylinder 27 is started, the detection piece 29 is extended and contacted with the tool, first, the temperature sensor detects the temperature of the current tool, and the tool temperature that can be recycled to the tool magazine is set as T, and the current temperature of the tool detected by the temperature sensor is T1; When T1≤T, it indicates that the current tool temperature is appropriate, and the tool can be directly recycled to the corresponding tool seat 4 on the tool magazine through the tool changer 25; When T1>T, it indicates that the current tool temperature is too high, and the tool cannot be directly recycled to the corresponding tool seat 4 on the tool magazine, at this time, the passage of the shunt valve 161 and the branch pipe 17 is opened, so that the lubricating oil is sprayed from the oil outlet hole on the detection piece 29 to the surface of the tool, and the tool is quickly cooled; after single oil injection, the temperature sensor detects the temperature of the tool surface again, if T1 is still greater than T at this time, it indicates that the cooling effect is not ideal, and the oil is continuously sprayed to the surface of the tool for cooling until T1≤T is detected by the temperature sensor; Further, in order to prevent long time pause during the cooling process, resulting in delay of the work at the numerical control machine tool, after N3 times of oil injection and cooling, if T1 is still greater than T, the tool is preferentially recycled to the corresponding tool seat 4 on the tool magazine, and the tool changing work at the numerical control machine tool is completed, at this time, the driving part 7 is driven again to perform self-lubricating operation, that is, the oil cavity 11 inside the tool magazine is opened for multiple cycles, so as to lubricate and cool the entire tool magazine, and reduce the influence of the current high-temperature tool on the tool magazine.

[0031] Further, if the temperature T1≤T of the tool surface is detected again by the temperature sensor after single or multiple oil injection, at this time, the second cylinder 27 drives the detection piece 29 to continue to extend until the pressure sensor feedback value reaches the preset threshold value, that is, the detection piece 29 is in close contact with the surface of the tool, at this time, the remote control end sends a command to start the hardness detection program, the second cylinder 27 continues to drive the detection piece 29 to displace towards the tool, the elastic contraction amount of the telescopic spring is received by the pressure sensor, and the hardness value H1 of the tool is converted by the data processing system, and compared with the initial hardness value H0 of the tool, H0 is stored in the database of the remote control end; If |H1-H0|≤5% H0, it is determined that the current tool hardness is qualified, and the tool holder 25 performs a tool collecting action; if |H1-H0|>5% H0, the remote control end automatically triggers a secondary cooling process, the diverter valve 161 is switched to the oil injection mode, and the drive part 7 controls the chain plate 3 to run at a low speed, so that the tool rotates uniformly during the cooling and oil injection process. The hardness detection is repeated after each cooling cycle until the hardness deviation meets the requirements. At this time, the remote control end sends a tool failure warning and locks the position of the tool holder 4.

[0032] Through the above embodiment, the concave surface of the detection piece 29 is integrated with a temperature sensor, the connecting plate 28 is additionally provided with a telescopic spring with a pressure sensor, the tool temperature is detected during tool changing, and the tool is cooled by oil injection to an appropriate temperature when the temperature is too high. Then, the spring extension amount fed back by the pressure sensor is converted into a hardness value for comparison with the initial value. If it is qualified, the tool is collected. If it is unqualified, the secondary cooling is triggered and the tool is uniformly cooled by rotating. After the hardness deviation meets the requirements or reaches the upper limit of cooling, the tool holder is locked, thereby realizing double detection and regulation of the tool temperature and hardness. At the same time, through the closed-loop control of temperature detection, hardness detection, and lubrication compensation, the chain transmission precision is improved by dynamic adjustment of the lubrication system while preventing high-temperature tools from damaging the tool magazine. The overall operation reliability of the tool magazine is improved, the tool life is extended, the tool magazine is effectively prevented from being damaged by tools with residual heat, the tool performance is guaranteed, and the use safety of the tool magazine and the tool recovery reliability are improved.
