[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] Please see Figure 1-2 This utility model provides a technical solution: an automatic tool changer spindle protection device, including a spindle 1, with a blade 2 installed at the output end of the spindle 1, and further including: a protection component 3, which is disposed on the outside of the blade 2 and is used to protect the blade 2; a positioning component 4, which is disposed on the outside of the spindle 1 and whose bottom surface is connected to the top of the protection component 3, and is used to support the protection component 3; two pulling components 5, which are respectively disposed at the bottom of the two side walls of the protection component 3 and pass through the middle of the two side walls of the positioning component 4, and are used to pull the protection component 3 to retract or expand; and two pushing components 6, which are respectively disposed on both sides of the top surface of the positioning component 4, with the output ends of the two positioning components 4 respectively connected to the two pulling components 5, and are used to drive the pulling components 5 to rise and fall;

[0035] The spindle 1 can be installed in a designated position on the machine tool, and the insert 2 and positioning assembly 4 can also be installed. The positioning assembly 4 can be used to insert and install the two pull assemblies 5, and also provides a mounting base for the protective assembly 3 and the two push assemblies 6. When protection is needed at the connection between the insert 2 and the spindle 1, the retraction of the two push assemblies 6 can drive the pull assemblies 5 to move downwards synchronously, thereby pushing the protective assembly 3 to unfold. This allows the protective assembly 3 to protect the connection between the insert 2 and the spindle 1, preventing cutting fluid and debris from entering the connection area and ensuring the stability of the spindle 1 when replacing the insert 2. When the insert 2 needs to be replaced, the extension of the push assembly 6 can pull the protective assembly 3 to retract via the pull assemblies 5, thereby exposing the connection between the spindle 1 and the insert 2, facilitating the replacement of the insert 2 by the spindle 1, and improving the convenience of replacing the insert 2.

[0036] See Figure 1 , Figure 3 The protective component 3 includes a support frame 31, a bellows cover 32 is provided on the top surface of the support frame 31, and the top of the bellows cover 32 is connected to the bottom of the positioning component 4; a positioning plate 33 for connecting the bottom of the pulling component 5 is fixedly provided in the middle of both side walls of the support frame 31.

[0037] The support frame 31 in the protective component 3 can support the bottom of the bellows cover 32 to prevent the bellows cover 32 from affecting the operation of the blade 2. It can also install two pulling components 5 through two positioning plates 33. Then, through the bellows cover 32, it can protect the blade 2 and fix its top to the positioning component 4. It can also extend and retract flexibly, thereby improving its protective effect on the blade 2.

[0038] See Figure 3 , Figure 4 The positioning component 4 includes a retaining ring 41 that is sleeved on the outside of the main shaft 1. The top surface of the retaining ring 41 has two semi-rings 42 on both sides at the middle position. The two semi-rings 42 on the same side are connected by fixing bolts 43. The middle of both sides of the retaining ring 41 is provided with guide rings 44 for inserting and pulling the component 5.

[0039] The retaining ring 41 in the positioning component 4 can be fitted onto the outside of the main shaft 1, and can also be used to install the two half rings 42 and the two guide rings 44. At the same time, it can also be used to fix the top of the bellows cover 32. The two half rings 42 can be used with two fixing bolts 43 to firmly fix them to the main shaft 1, thereby improving the stability of the retaining ring 41. Then, the two guide rings 44 can be used to insert and install the pulling component 5, and can also guide the pulling component 5, thereby improving the smoothness of its lifting and lowering.

[0040] See Figures 3-6 The pulling component 5 includes a guide post 51 inserted into the inner cavity of the guide ring 44, the bottom end of the guide post 51 being connected to the top surface of the positioning plate 33; a groove 52 is provided on the side wall of the guide post 51 near the top end, and an elastic element 53 is provided in the inner cavity of the groove 52, the movable end of the elastic element 53 being connected to the movable end of the pushing component 6; the elastic element 53 includes a C-shaped frame 531 provided in the inner cavity of the groove 52, a cylinder 532 is provided in the inner cavity of the C-shaped frame 531, a slider 533 is inserted into the cylinder 532, and one end of the slider 533 is in contact with the inner wall of the C-shaped frame 531; a spring 534 is sleeved on the cylinder 532, the top and bottom ends of the spring 534 being connected to the bottom surface of the slider 533 and the bottom surface of the inner cavity of the C-shaped frame 531, respectively; an internal thread groove 535 is provided at the other end of the slider 533, and the internal thread groove 535 is connected to the pushing component 6;

[0041] By pulling the guide post 51 in component 5, it can be fixed to the top surface of the positioning plate 33 and flexibly inserted into the inner cavity of the guide ring 44. Simultaneously, it provides space for the groove 52, through which the C-shaped frame 531 can be installed and fixed. Since the inner cavity of the C-shaped frame 531 has a cylinder 532, and a slider 533 is inserted into the cylinder 532, with one end of the slider 533 fitting against the inner wall of the C-shaped frame 531, the slider 533 can smoothly and flexibly rise and fall on the cylinder 532. Furthermore, since the top and bottom ends of the spring 534 are connected to the bottom surface of the slider 533 and the bottom surface of the inner cavity of the C-shaped frame 531 respectively, and one end of the slider 533 is connected to… The internal thread groove 535 is connected to the push assembly 6. Therefore, by extending and retracting the push assembly 6, the C-shaped frame 531 can be driven to rise and fall synchronously via the slider 533 and the spring 534. This allows for adjustment of the position of the guide column 51, enabling the bellows cover 32 to be unfolded or folded to protect the connection between the main shaft 1 and the blade 2. Furthermore, under the linkage of the spring 534, the support frame 31 can be compressed when it is subjected to a downward collision, giving the support frame 31 a certain range of motion and reducing damage to the support frame 31. At the same time, under the elastic force of the spring 534, it can be reset, ensuring the protective effect of the bellows cover 32 on the support frame 31 on the blade 2.

[0042] See Figure 4 , Figure 6 and Figure 7 The pushing component 6 includes a hollow seat 61 disposed on one side of the top surface of the positioning component 4. An electric push rod 62 is disposed in the inner cavity of the hollow seat 61. A top plate 63 is installed on the telescopic end of the electric push rod 62. A screw 64 is disposed in the middle of one end of the top plate 63. The screw 64 is rotatably connected to the inner cavity of the internal thread groove 535. An internal thread hole 65 is opened on one side wall of the hollow seat 61 near the top end. A locking screw 66 is rotatably connected to the inner cavity of the internal thread hole 65.

[0043] By pushing the hollow seat 61 in component 6, it can be fixed to one side of the top surface of the retaining ring 41 and the electric push rod 62 can be inserted and installed. Then, by rotating the locking screw 66 in the internal threaded hole 65, the electric push rod 62 can be prevented from falling out of the hollow seat 61, thus ensuring the stability of the installation. Then, through the top plate 63, it can be installed at the telescopic end of the electric push rod 62 and can also be rotated and installed at the internal threaded groove 535 on the slider 533 via the screw 64. Therefore, by the telescopic movement of the electric push rod 62, the slider 533 can be moved up and down synchronously.

[0044] During operation, the spindle 1 can be installed in a designated position on the machine tool, and the insert 2 and positioning assembly 4 can also be installed. The positioning assembly 4 can be used to connect and install the two pull assemblies 5, and also provides a mounting base for the protective assembly 3 and the two push assemblies 6. When protection is needed at the connection between the insert 2 and the spindle 1, the retraction of the two push assemblies 6 can drive the pull assemblies 5 to move downwards synchronously, thereby pushing the protective assembly 3 to unfold. This allows the protective assembly 3 to protect the connection between the insert 2 and the spindle 1, preventing cutting fluid and debris from entering the connection area and ensuring the stability of the spindle 1 when replacing the insert 2. When the insert 2 needs to be replaced, the extension of the push assembly 6 can pull the protective assembly 3 to retract via the pull assemblies 5, thereby exposing the connection between the spindle 1 and the insert 2, facilitating the replacement of the insert 2 by the spindle 1, and improving the convenience of replacing the insert 2.

[0045] The support frame 31 in the protective component 3 can support the bottom of the bellows cover 32 to prevent the bellows cover 32 from affecting the operation of the blade 2. It can also install two pulling components 5 through two positioning plates 33. Then, through the bellows cover 32, it can protect the blade 2 and fix its top to the positioning component 4. It can also extend and retract flexibly, thereby improving its protective effect on the blade 2.

[0046] The retaining ring 41 in the positioning component 4 can be fitted onto the outside of the main shaft 1, and can also be used to install the two half rings 42 and the two guide rings 44. At the same time, it can also be used to fix the top of the bellows cover 32. The two half rings 42 can be used with two fixing bolts 43 to firmly fix them to the main shaft 1, thereby improving the stability of the retaining ring 41. Then, the two guide rings 44 can be used to insert and install the pulling component 5, and can also guide the pulling component 5, thereby improving the smoothness of its lifting and lowering.

[0047] By pulling the guide post 51 in component 5, it can be fixed to the top surface of the positioning plate 33 and flexibly inserted into the inner cavity of the guide ring 44. Simultaneously, it provides space for the groove 52, through which the C-shaped frame 531 can be installed and fixed. Since the inner cavity of the C-shaped frame 531 has a cylinder 532, and a slider 533 is inserted into the cylinder 532, with one end of the slider 533 fitting against the inner wall of the C-shaped frame 531, the slider 533 can smoothly and flexibly rise and fall on the cylinder 532. Furthermore, since the top and bottom ends of the spring 534 are connected to the bottom surface of the slider 533 and the bottom surface of the inner cavity of the C-shaped frame 531 respectively, and one end of the slider 533 is connected to… The internal thread groove 535 is connected to the push assembly 6. Therefore, by extending and retracting the push assembly 6, the C-shaped frame 531 can be driven to rise and fall synchronously via the slider 533 and the spring 534. This allows for adjustment of the position of the guide column 51, enabling the bellows cover 32 to be unfolded or folded to protect the connection between the main shaft 1 and the blade 2. Furthermore, under the linkage of the spring 534, the support frame 31 can be compressed when it is subjected to a downward collision, giving the support frame 31 a certain range of motion and reducing damage to the support frame 31. At the same time, under the elastic force of the spring 534, it can be reset, ensuring the protective effect of the bellows cover 32 on the support frame 31 on the blade 2.

[0048] By pushing the hollow seat 61 in component 6, it can be fixed to one side of the top surface of the retaining ring 41 and the electric push rod 62 can be inserted and installed. Then, by rotating the locking screw 66 in the internal threaded hole 65, the electric push rod 62 can be prevented from falling out of the hollow seat 61, thus ensuring the stability of the installation. Then, through the top plate 63, it can be installed at the telescopic end of the electric push rod 62 and can also be rotated and installed at the internal threaded groove 535 on the slider 533 via the screw 64. Therefore, by the telescopic movement of the electric push rod 62, the slider 533 can be moved up and down synchronously.

[0049] In summary, the device can drive the pulling component 5 to move downward synchronously by retracting the two pushing components 6, thereby pushing the protective component 3 to unfold. This allows the protective component 3 to protect the connection between the blade 2 and the spindle 1, preventing the cutting fluid from carrying debris into the connection area and ensuring the stability of the spindle 1 when replacing the blade 2.
