Therefore, they cannot be understood as limitations on the present invention. The terms "connected", "connected" and "set" used in the present invention should be understood in a broad sense, for example, they can be fixedly connected or detachably connected; they can be directly connected or indirectly connected through an intermediate component; they can be wired electrical connections, radio connections, or wireless communication signal connections. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0036] like Figure 2 As shown, the embodiment of the utility model provides a CNC lathe cutter head rod disassembly and assembly device, comprising a sleeve 1 and a rotating tool. The sleeve 1 has a contour hole 11 corresponding to the end 41 of the cutter head rod 4 at one end, and a connecting hole 12 at the other end, through which the rotating tool is detachably connected to the sleeve 1. Figure 3-Figure 5As shown, in this embodiment, the contoured hole 11 includes opposite first walls 111 and opposite second walls 112 , the first wall 111 is a straight surface, and the second wall 112 is a curved surface with a convex arc cross section.

[0037] When the tool disc push rod disassembly and assembly device for a CNC lathe provided by the embodiment of the utility model is in use, the sleeve 1 is sleeved on the end 41 of the tool disc push rod 4, and then a rotating tool (such as a rotating rod, inserted into the connecting hole of the sleeve 1) is connected to the connecting hole 12 of the sleeve 1. Due to the extension of the sleeve 1, the rotating tool avoids the adjacent end 41 of the push rod 4, which provides space for operation, that is, the end 41 of the push rod 4 can be rotated at a large angle, which can reduce the working intensity and improve the working efficiency. In addition, due to the increase in the operating space, the risk of the operator being injured by hitting the adjacent push rod 4 is reduced.

[0038] In a preferred embodiment of the utility model, the rotary tool is a ratchet wrench 2, which includes a handle 21 and a ratchet structure 22 at the end of the handle, and a first connecting column 23 is fixedly provided on the side of the ratchet structure 22, and the cross section of the first connecting column 23 is a regular polygon, such as a square. The opening direction of the connecting hole 12 is opposite to that of the contoured hole 11, and the axis coincides, and the shape of the connecting hole 12 corresponds to the shape of the first connecting column 23, so that the first connecting column 23 is not easy to loosen after being inserted into the connecting hole 12 and efficiently transmits torque.

[0039] After the first connecting column 23 of the ratchet wrench 2 is inserted into the connecting hole 12 of the sleeve 1, the ratchet wrench 2 can be inserted into the sleeve once, without the need to remove the wrench and make the wrench and the push rod 4 for many times like using an ordinary wrench, which reduces the number of repeated operations and the intensity of the operation, and eliminates the risk of collision when using an ordinary wrench to make multiple matches with the push rod 4. In the prior art, since the use of a wrench to rotate the end 41 of the push rod 4 requires repeated matching of the wrench and the end 41, and it is inconvenient to apply force, an operator needs to operate with both hands, and another operator needs to simultaneously screw the nut 42 at the end of the push rod 4 at the tool holder. When the CNC lathe cutter head push rod disassembly and assembly device provided by the embodiment of the utility model is in use, the sleeve 1 is put on the end 41 of the cutter head push rod 4, and the ratchet wrench 2 can be used to achieve the fit (sleeve 1) only once, without the need to remove the wrench many times and then make the wrench and the push rod 4 fit together many times like using an ordinary wrench, so that one person only needs to operate the ratchet wrench with one hand and twist the nut 42 at the end of the push rod 4 with the other hand, and the operation can be easily carried out without the cooperation of two people.

[0040] In order to prevent the ratchet wrench 2 from loosening from the sleeve 1 and the collision with the surrounding push rod 4 caused by the loosening, causing injuries to the operator's hands, Figure 2 , Figure 6As shown, the side of the first connecting column 23 is provided with a locking ball 24 protruding from the surface of the first connecting column 23, and the inner wall of the connecting hole 12 is provided with a ball locking slot 13. The locking ball 24 is connected to an elastic device, such as a spring, so that when it is inserted into the connecting hole 12 of the sleeve 1, it is pressed by the inner wall of the connecting hole 12 and can be retracted into the inside of the side of the first connecting column 23. When the first connecting column 23 is inserted into the connecting hole 12 of the sleeve 1 and is in place, the locking ball 24 is just located at the ball locking slot 13 of the connecting hole 12 and pops out of the ball locking slot 13 under the action of elastic force, thereby hindering the displacement between the first connecting column 23 and the connecting hole 12. Furthermore, the end of the connecting hole 12 is provided with a guide slot 14 corresponding to the ball locking slot 13, so that the process of pressing the locking ball 24 by the end of the connecting hole 12 is smoother, thereby preventing the first connecting column 23 from being unable to be inserted into the connecting hole 12. Furthermore, each inner wall of the connecting hole 12 is provided with the ball locking slot 13, so that no matter at which angle the locking ball 24 of the first connecting column 23 is inserted into the connecting hole 12, there is a ball locking slot 13 corresponding to it, which is convenient for operators to operate.

[0041] In one embodiment of the utility model, an extension rod is provided between the sleeve 1 and the ratchet wrench 2, one end of the extension rod is provided with a second connection column corresponding to the shape of the connection hole 12, and the other end of the extension rod is provided with a socket corresponding to the shape of the first connection column 23. The extension rod makes the operating position of the rotary tool further away from the end 41 of the cutter head 4, so that the operating space is larger, the operating difficulty is further reduced, the operating efficiency is improved, and because the operating space is further increased, the risk of injury to the operator due to touching the adjacent top rod 4 is further reduced.

[0042] like Figure 7 , Figure 8 As shown, in one embodiment of the utility model, in order to prevent the sleeve 1 from loosening from the end 41 of the cutter head rod 4, a locking plate 15 is provided on the side of one end of the sleeve 1 provided with the profiling hole 11. The locking plate 15 is connected to the sleeve 1 through a rotating shaft 16. The locking plate 15 can rotate around the rotating shaft 16 and block the profiling hole 11. After the sleeve 1 is inserted into the end 41 of the cutter head rod 4, the locking plate 15 rotates to a position to block the profiling hole 11 and abuts against the inner side of the end 41 of the cutter head rod 4, thereby preventing the end 41 of the cutter head rod 4 from loosening from the sleeve 1. When the locking plate 15 rotates to not block the profiling hole 11, for example, rotates to the outside of the sleeve 1, the sleeve 1 can be separated from the end 41 of the cutter head rod 4. Preferably, a torsion spring is sleeved on the rotating shaft 16 to enable the locking plate 15 to normally keep covering the contoured hole 11 to prevent the locking plate 15 from accidentally rotating to a position where the sleeve 1 and the end 41 of the cutter head rod 4 can be separated.

[0043] The tool head rod disassembly and assembly device for a CNC lathe provided by the embodiment of the utility model can solve the problems of using ordinary wrenches to disassemble and assemble the tool head rod in the prior art, such as: the wrench is not easy to use, the operating efficiency is low, and the equipment downtime is long; two people are required to cooperate tacitly at the same time, and there are many operators; the working position is small, the activity space is limited, it is difficult to apply force, and there is a safety risk of people being injured; repeated operations cause physical fatigue of the operators, which is not in line with ergonomics. Using the tool head rod disassembly and assembly device for a CNC lathe provided by the embodiment of the utility model, the operating efficiency can be improved by about 75%, only one person is needed to operate, one operator is reduced, and the risk of collision caused by repeated cooperation is eliminated. The use of a special socket in combination with a ratchet wrench can reduce the labor intensity of the operators' repeated actions and improve ergonomics.

[0044] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
