Background
The numerical control machining industry develops faster, and the demand forms of the equipment host machine for numerical control machining on tool magazine are more and more varied. Unlike the structure of the cutter sleeve sealed inside the cutter bin frame, the cutter sleeve assembly runs along with the chain plate mechanism inside the cutter bin and is fixed onto the chain plate, and the chain plate mechanism stops in proper position for cutter changing and is not separated from the chain plate. However, for some non-standard tool-making libraries, the tool-changing action is often required to be completed by constraining the tool sleeve component to leave the chain plate and the tool bin during tool changing. The existing closed limiting plate structure cannot meet the requirements, and a mechanism capable of realizing mechanical locking of the cutter sleeve and the chain plate and unlocking and disconnecting to change the cutter at a designated position needs to be developed according to the situation.

The invention relates to a knife sleeve chain plate locking mechanism, which comprises a chain plate mechanism which is positioned in a knife bin body and can run along a guide rail plate, wherein the chain plate mechanism comprises a pair of chain plates which are arranged in parallel, the chain plates are connected through a chain plate mandrel, a spacer bush is sleeved on the chain plate mandrel between the two chain plates, bearings matched with the guide rail plate are respectively arranged at two ends of the chain plate mandrel, a knife sleeve assembly is arranged on the chain plate, the knife sleeve assembly is located on the chain plate, a positioning key is fixed on the knife sleeve assembly, a spring seat is positioned between the two chain plates, one side of the spring seat is fixedly connected with one chain plate, the other side of the spring seat is rotationally connected with a locking hook through the locking hook mandrel, one end hook body part of the locking hook is matched with the positioning key, the other end of the locking hook is fixedly provided with a first positioning pin, a spring is arranged in the spring seat, one end of the spring is sleeved on the first positioning pin and the end of the spring is propped against one end of the locking hook, a spring limiting plate is fixedly arranged on the spring seat, the other end of the spring is propped against the spring limiting plate, a second limiting pin is fixedly arranged on the spring limiting plate, and the other end of the spring is sleeved on the second limiting pin;
the knife bin body is fixedly provided with a bracket, an air cylinder connected with the pneumatic control device is fixed on the bracket, and the outer end of a piston rod matched with the air cylinder is matched with the end of the locking hook.
Compared with the prior art, the cutter sleeve chain plate locking mechanism can be relatively fixed and locked between the cutter sleeve component and the chain plate, and can also be unlocked and separated according to the requirement, so that the requirement that the cutter sleeve component part in the non-calibrated cutter manufacturing warehouse leaves the chain plate and the constraint of the cutter bin to complete cutter changing action is met, and the cutter sleeve chain plate locking mechanism has the advantages of simple structure and flexible and reliable action.

Detailed Description
As shown in fig. 1 to 5: the knife sleeve chain plate locking mechanism comprises a chain plate mechanism which is positioned in a knife bin body 19 and can run along a guide rail plate 20, wherein the chain plate mechanism comprises a pair of chain plates 3 which are arranged in parallel, and the chain plates 3 are connected through a chain plate mandrel 6. The chain plate mandrel 6 positioned between the two chain plates 3 is sleeved with the spacer bush 4. The two ends of the chain plate mandrel 6 are respectively provided with a bearing 5 matched with the guide rail plate 20, and the chain plate assembly is driven to move along the guide rail plate 20 through the bearings 5. The chain plate 3 is provided with a cutter sleeve component 1. The knife sleeve assembly 1 is located on the chain plate 3, and the fixed locking structure is as follows: a positioning key 7 is fixed on the tool sleeve assembly 1 through a connecting bolt 22. The spring seat 10 is located between two link plates 3, and one side of the spring seat 10 is fixedly connected with one of the link plates 3 through a fixing bolt 17. The other side of the spring seat 10 is rotatably connected with a locking hook 2 through a locking hook mandrel 8, and one end hook body part of the locking hook 2 is matched with the positioning key 7. The other end of the locking hook 2 is fixed with a first positioning pin 12. A spring 11 is arranged in the spring seat 10, one end of the spring 11 is sleeved on the first positioning pin 12, and the end of the spring 11 abuts against one end of the locking pin 2. The spring seat 10 is fixedly provided with a spring limiting plate 9 through a second screw 16, the other end of the spring 11 is propped against the spring limiting plate 9, the spring limiting plate 9 is fixedly provided with a second limiting pin 21, and the other end of the spring 11 is sleeved on the second limiting pin 21. A locking pin limiting plate 13 is fixedly connected to the spring seat 10 through a first screw 15 for limiting the rotation (lateral) of the locking hook 2. The cutter sleeve assembly is buckled on a positioning key 7 arranged on the cutter sleeve assembly 1 under the action of a spring 11, and the contact surface of the locking hook 2 and the positioning key 7 is an arc surface, so that the cutter sleeve assembly 1 and the chain plate 3 are relatively fixed and locked. The first and second stopper pins 12 and 21 guide the spring 11.
The knife compartment body 19 is fixedly provided with a bracket 18, the air cylinder 14 connected with the pneumatic control device is fixed on the bracket 18, and the outer end of the piston rod 23 matched with the air cylinder 14 is matched with the end of the locking hook 2.
In the working process, the cutter sleeve assembly 1 and the chain plate 3 are in a locking state in a free state, when the chain plate is in a cutter changing position, a piston rod of the unlocking cylinder 14 stretches out to push the locking hook 2 to be separated from the positioning key 7 on the cutter sleeve assembly 1, so that unlocking is realized. In the locking state, the chain plate is contacted with the positioning surface outside the cutter sleeve and realizes the positioning in the angle direction and the axial direction, and the locking hook 2 hooks the positioning key 7 arranged on the cutter sleeve assembly 1 under the action of the spring 11, so that the cutter sleeve assembly and the chain plate 3 can be completely positioned in three directions.
