[0002] A center is a machine tool component used in machining. There are two types: fixed centers and movable centers. Fixed centers can support parts with complex end faces and parts for which center holes cannot be drilled.

[0003] Existing actuating centers are prone to wear and tear, requiring regular replacement and maintenance. Since the centers are installed using bolts, disassembly and reassembly are laborious and slow, impacting workpiece processing efficiency and making them inconvenient to use. Therefore, we propose an easily replaceable actuating center to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an easily replaceable actuating tip to solve the problems currently existing in the market as described in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a replaceable actuating tip, including a mounting handle, one end of which is rotatably connected to an actuating end plate, and the end of the actuating end plate away from the mounting handle having a mounting groove, wherein...

[0006] A top is provided in the mounting groove, and slots are symmetrically opened on the inner walls of both sides of the mounting groove. A locking block is fixedly connected to the outer side of the top corresponding to the slot. A baffle groove is opened in the interior of the actuating end plate near the mounting groove. A baffle is provided in the baffle groove. The mounting groove and the baffle groove are connected through a rod insertion groove. A slot is opened at one end of the top near the rod insertion groove. A rod is fixedly connected to one end of the baffle corresponding to the rod insertion groove.

[0007] A spring is installed between the end of the baffle away from the insertion rod and the inner wall of the baffle groove. A push rod groove is opened at the end of the actuating end plate near both sides of the mounting groove. The push rod groove is connected to the baffle groove. A push rod is fixedly connected to the side of the baffle near the push rod groove. A protective cover is fixedly installed at the end of the actuating end plate corresponding to the outer side of the push rod. The mounting structure of the tip is sealed by a sealing mechanism.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention allows for the replacement of a tip by simultaneously pushing the push rods on both sides. The push rods, via the baffle, drive the insert rod to overcome the spring force and move out of the slot, enabling the tip to rotate. This rotation causes the locking block to move out of the slot, completing the tip disassembly. Afterward, the tip to be installed is removed. When the tip enters the mounting slot, it pushes the insert rod to overcome the spring force and retract into the insert rod slot. Simultaneously, the locking block enters the slot and, through rotation, engages with the L-shaped slot. The insert rod slot and slot are then aligned. The spring drives the insert rod into the slot, preventing the tip from rotating and causing the locking block to move out of the slot. This completes the tip installation. This tip installation structure allows for quick and easy disassembly and assembly of tips, facilitating repair or replacement.

[0015] This invention uses a protective cover to shield the protruding push rod, preventing accidental contact that could loosen the mounting of the tip. The inner wall of the protective cover is sealed to the push rod via a first sealing ring, and a second sealing ring is fitted over the outside of the tip. This allows the second sealing ring to pull the sealing plug into the opening of the slot. The second sealing ring and the sealing plug, in conjunction with the first sealing ring, seal the mounting structure of the tip, preventing coolant from entering the interior of the tip mounting structure and thus protecting it.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: an easily replaceable actuating tip, including a mounting handle 1, one end of which is rotatably connected to an actuating end plate 2, and the end of the actuating end plate 2 away from the mounting handle 1 having a mounting groove 3, wherein...

[0024] The mounting slot 3 is provided with a top point 4. The inner walls on both sides of the mounting slot 3 are symmetrically provided with slots 5. The top point 4 is fixedly connected to the outer side of the slot 5 with a block 6. The inside of the actuating end plate 2 near the mounting slot 3 is provided with a baffle slot 7. A baffle 8 is provided in the baffle slot 7. The mounting slot 3 and the baffle slot 7 are connected through a rod slot 9. The top point 4 is provided with a slot 10 near the rod slot 9. A rod 11 is fixedly connected to the end of the baffle 8 corresponding to the rod slot 9.

[0025] A spring 12 is installed between the end of the baffle 8 away from the insertion rod 11 and the inner wall of the baffle groove 7. The ends of the actuating end plate 2 near the mounting groove 3 are provided with push rod grooves 13, which are connected to the baffle groove 7. A push rod 14 is fixedly connected to the side of the baffle 8 near the push rod groove 13. A protective cover 15 is fixedly installed on the end of the actuating end plate 2 corresponding to the outer side of the push rod 14. The mounting structure of the tip 4 is sealed by a sealing mechanism.

[0026] Please see Figures 1 to 5 The slot 5 is L-shaped, and the internal dimensions of the slot 5 match the external dimensions of the block 6. The insertion rod 11 is rectangular column, and the external dimensions of the insertion rod 11 match the internal dimensions of the slot 10. The push rod 14 is fixedly connected to the insertion rod 11 through the baffle 8.

[0027] When the tip 4 needs to be replaced, push the push rods 14 on both sides simultaneously. The push rods 14 drive the insert rod 11 through the baffle 8 to overcome the elastic force of the spring 12 and move it out of the slot 10. This allows the tip 4 to rotate, and the rotation of the tip 4 can drive the locking block 6 to move out of the slot 5, thus completing the disassembly of the tip 4. Then, take out the tip 4 to be installed. When the tip 4 enters the installation slot 3, the tip 4 pushes the insert rod 11 to overcome the elastic force of the spring 12 and retracts into the insert rod slot 9. At the same time, after the locking block 6 enters the slot 5, it is rotated to lock the locking block 6 into the L-shaped slot 5. At the same time, the insert rod slot 9 and the slot 10 are just aligned. The spring 12 drives the insert rod 11 to insert into the slot 10, preventing the tip 4 from moving the locking block 6 out of the slot 5 by rotation. This completes the installation of the tip 4. Through this installation structure of the tip 4, the tip 4 can be quickly disassembled and assembled, so that the tip 4 can be disassembled, repaired, or replaced.

[0028] Please see Figures 1 to 5 The sealing mechanism includes a first sealing ring 16. The inner wall of the protective cover 15 is fitted with the first sealing ring 16, which is sealed to the push rod 14 via the first sealing ring 16. A second sealing ring 17 is fitted on the outer side of the tip 4. A sealing plug 18 is fixedly connected to the opening of the slot 5 corresponding to the second sealing ring 17. The second sealing ring 17 is annular, and the outer dimensions of the sealing plug 18 match the dimensions of the opening of the slot 5. The protective cover 15 shields the protruding push rod 14 to prevent accidental contact with the push rod 14, which could cause the tip 4 to become loose. The inner wall of the protective cover 15 is sealed to the push rod 14 via the first sealing ring 16. The second sealing ring 17 is fitted on the outer side of the tip 4, allowing the second sealing ring 17 to drive the sealing plug 18 into the opening of the slot 5. The second sealing ring 17 and the sealing plug 18, in conjunction with the first sealing ring 16, seal the mounting structure of the tip 4, preventing coolant from entering the interior of the tip 4 mounting structure, thus protecting the mounting structure of the tip 4.

[0029] Working principle: This easy-to-replace actuating tip, when the tip 4 needs to be replaced, simultaneously pushes the push rods 14 on both sides, causing the push rods 14 to move the insertion rod 11 out of the slot 10 through the baffle 8, overcoming the elastic force of the spring 12. This allows the tip 4 to rotate, and the rotation of the tip 4 causes the locking block 6 to move out of the slot 5, completing the removal of the tip 4. After that, the tip 4 to be installed is taken out, and when the tip 4 enters the installation slot 3, the tip 4 pushes the insertion rod 11 to retract into the insertion rod slot 9, overcoming the elastic force of the spring 12. At the same time, after the locking block 6 enters the slot 5, it is rotated to lock the locking block 6 into the L-shaped slot 5. At the same time, the insertion rod slot 9 and the slot 10 are just aligned. The spring 12 drives the insertion rod 11 to insert into the slot 10, preventing the tip 4 from moving the locking block 6 out of the slot through rotation. Once the tip 4 is inserted into the slot 5, its installation can be completed. This installation structure allows for quick assembly and disassembly of the tip 4, facilitating repair or replacement. A protective cover 15 shields the protruding push rod 14, preventing accidental contact and potential loosening of the tip 4. The inner wall of the protective cover 15 is sealed to the push rod 14 via a first sealing ring 16. A second sealing ring 17 is fitted over the outside of the tip 4, causing the sealing plug 18 to enter the opening of the slot 5. The second sealing ring 17 and the sealing plug 18, in conjunction with the first sealing ring 16, seal the installation structure of the tip 4, preventing coolant from entering and protecting the tip 4's installation structure.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
