Description
Technical Field
[0001] This utility model relates to the field of machine tool tool changing technology, and in particular to an integrated automatic tool changing device for vertical deep hole drilling. Background Technology
[0002] In deep hole drilling, guide bushings guide and support the cutting tool to prevent vibration and bending. The deep hole drilling tool is mounted on the spindle, and the guide bushing is mounted on the drill bushing bracket below the spindle. During machining, the tool passes through the guide hole of the guide bushing and then drills the workpiece downwards. The guide hole ensures the stability of the tool, causing the tool to grind against the guide hole, which reduces the service life of the guide bushing. In addition, each tool needs to be paired with a corresponding guide bushing, and the corresponding guide bushing must be replaced after tool change, which increases the tool change time and affects production efficiency. Moreover, the guide bushing and the tool need to be stored separately, occupying the space of the tool magazine and reducing the number of tools that the machine tool can store. Utility Model Content

[0010] In some embodiments, the link includes two symmetrically arranged connecting arms, each of which is fitted with a support shaft, and a notch is formed between the two connecting arms to allow for the connection sleeve to be positioned.
[0011] In some embodiments, the drill bushing bracket and the flange are provided with a communicating detection air passage, and the detection air passage has a detection hole exposed on the inner wall of the flange shaft hole that mates with the assembly surface.
[0012] In some embodiments, the mounting surface is a conical surface.
[0013] In some embodiments, the connecting sleeve has a central hole on the shaft portion that communicates with the assembly hole, and the guide sleeve is installed in the central hole.

[0031] The specific embodiments of this utility model are described with reference to the accompanying drawings.
[0032] refer to Figure 1The figure shows a three-dimensional structural diagram of a vertical deep hole drilling integrated automatic tool changer. The top is the machine head 101, the center of the machine head 101 is the spindle 102, and below the spindle 102 is the tool holder 7 (the drill bit is not shown). The outside of the tool holder 7 is the drill sleeve bracket 1, and the position of the drill sleeve bracket 1 is the tool changing position. The bottom of the tool holder 7 is engaged with the connecting sleeve 8, and the shaft of the connecting sleeve 8 is engaged with the guide sleeve 9. When changing tools, the guide sleeve 9 is connected to the tool holder 7 through the connecting sleeve 8, so that they are removed from the spindle 102 along with the tool and stored in the tool magazine.
[0033] refer to Figures 1 to 6 An integrated automatic tool changer for vertical deep hole drilling is disposed between the spindle 102 of the head 101 and the drill sleeve support 1. It includes a connecting sleeve 8 and a lifting assembly 2. The connecting sleeve 8 has an assembly hole 81 at its axis that mates with the tool holder 7. The connecting sleeve 8 is fitted onto the tool holder 7 through the assembly hole 81 and stored in the tool magazine along with the tool. The outer wall of the connecting sleeve 8 has an assembly surface 82 that mates with the flange 11 of the drill sleeve support 1. The connecting sleeve 8 is secured within the flange 11 through the assembly surface 82 and engages with the tool on the spindle 102 via a guide sleeve 9 on the connecting sleeve 8 for deep hole drilling. The lower end face of the connecting sleeve 8 has a contact surface 85 that mates with the lifting assembly 2. The lifting assembly 2 is located below the drill sleeve support 1. During tool changing, the lifting assembly 2 lifts the connecting sleeve 8 and, with the cooperation of the spindle 102, drives the connecting sleeve 8 to move between the flange 11 and the tool holder 7.
[0034] The vertical deep hole drilling integrated automatic tool changer of this application uses a connecting sleeve 8 to adapt to the guide sleeve 9, tool holder 7 and flange 11. It is engaged with the tool holder 7 through the mounting hole 81, so that the connecting sleeve 8 and the guide sleeve 9 can be stored in the tool magazine as a whole with the tool, avoiding the guide sleeve 9 occupying the space of the tool magazine, and improving the tool changing efficiency. The connecting sleeve 8 is engaged with the flange 11 through the mounting surface 82, ensuring that the guide sleeve 9 is stably installed on the flange 11. The connecting sleeve 8 can be stably transferred between the tool holder 7 and the flange 11 by the lifting component 2.
[0035] In order for the connecting sleeve 8 to be snapped onto the tool holder 7, in this embodiment, reference is made to... Figure 3 The connecting sleeve 8 is provided with a first ball bearing 84 in the radial direction. The first ball bearing 84 protrudes from the inside of the mounting hole 81. The outer wall of the tool holder 7 is provided with a first groove 71 in the circumferential direction to cooperate with the first ball bearing 84.
[0036] Understandably, with this setup, the connecting sleeve 8 and the tool holder 7 can be quickly assembled and disassembled by plugging and unplugging. The first slot 71 is wrapped around the outer wall of the tool holder 7. The connecting sleeve 8 has four first mounting holes 86 at equal angles, which are arranged radially. Four first ball bearings 84 are installed in the first mounting holes 86. When the connecting sleeve 8 is to be fitted onto the tool holder 7, the lifting assembly 2 supports the connecting sleeve 8, and the spindle 102 drives the tool holder 7 downward to insert into the assembly hole 81. The four first ball bearings are engaged with the first slot 71, thereby securing the connecting sleeve 8 and the tool holder 7. When performing deep hole drilling, the connecting sleeve 8 needs to be separated from the tool holder 7 and mounted on the flange 11. The spindle 102 drives the tool holder 7 upward, and the connecting sleeve 8 is blocked by the flange 11, thus ensuring that the tool holder 7 can be pulled out from the assembly hole 81.
[0037] In order for the connecting sleeve 8 to be snapped into the shaft hole 16 of the flange 11, in this embodiment, reference is made to... Figure 3 and Figure 4 The flange 11 is provided with a second ball bearing 12 in the radial direction. The second ball bearing 12 protrudes from the inside of the shaft hole 16 of the flange 11. The mounting surface 82 is provided with a second groove 83 in the circumferential direction to cooperate with the second ball bearing 12.
[0038] Understandably, with this setup, the connecting sleeve 8 and flange 11 can be quickly disassembled and assembled using a plug-in method. The second slot 83 is wrapped around the assembly surface 82. The flange 11 has four second mounting holes 13 at equal angles, which are arranged radially. The four second ball bearings 12 are installed in the second mounting holes 13. When performing deep hole drilling, the connecting sleeve 8 needs to be separated from the tool holder 7 and locked in the shaft hole 16 of the flange 11. Under the support of the lifting assembly 2, the flange 11 can be pressed on the connecting sleeve 8, ensuring that the four second ball bearings 12 can be locked into the second slot 83. When changing tools, the spindle 102 will first lower the tool holder 7 and lock it into the assembly hole 81 of the connecting sleeve 8, and then drive the connecting sleeve 8 downwards, pushing the connecting sleeve 8 out of the shaft hole 16 of the flange 11.
[0039] To better facilitate the fitting of the connecting sleeve 8 with the tool holder 7 and flange 11, in this embodiment, reference is made to... Figures 1 to 4 The lifting assembly 2 includes a drive cylinder 3, a fixing plate 4, a connecting rod 5, and a guide plate 6. The drive cylinder 3 is fixed below the drill sleeve bracket 1. The fixing plate 4 is connected to the drive end of the drive cylinder 3 and pivotally connected to the connecting rod 5. The connecting rod 5 is provided with a support shaft 54 that cooperates with the contact surface 85. The guide plate 6 is installed below the drill sleeve bracket 1 and is located outside the flange 11. The guide plate 6 is provided with a guide groove 61. The drive cylinder 3 drives the connecting rod 5 and the support shaft 54 to move along the guide groove 61. The connecting sleeve 8 is lifted by moving to the support shaft 54 below the contact surface 85.
[0040] Understandably, with this configuration, the drive cylinder 3 acts as the power source, moving quickly and driving the connecting rod 5 and support shaft 54 to move rapidly. This allows the support shaft 54 to quickly approach and move away from the connecting sleeve 8, improving tool changing efficiency. Once the support shaft 54 moves below the contact surface 85 of the connecting sleeve 8, it can prevent the connecting sleeve 8 from disengaging from the shaft hole 16 of the flange 11. The connecting rod 5 is pivotally connected to the fixing plate 4 via a plug screw, ensuring that the connecting rod 5 has sufficient freedom to drive the support shaft 54 to move along the guide groove 61.
[0041] To facilitate the fitting of the connecting sleeve 8 and the flange 11, in this embodiment, refer to Figure 4 The guide groove 61 is divided into a first section 62 and a second section 64. There is a height difference between the first section 62 and the second section 64. A connecting section 63 is inclinedly arranged between the first section 62 and the second section 64.
[0042] Understandably, with this configuration, the guide groove 61 is Z-shaped, divided into a first section 62, a connecting section 63, and a second section 64. The first section 62 is away from the drill sleeve support 1, while the second section 64 is close to the drill sleeve support 1. That is, the height of the second section 64 is higher than the height of the first section 62. The height of the support shaft 54 in the second section 64 is also higher than its height in the first section 62. The support shaft 54 achieves height climbing in the connecting section 63. When it is necessary to lift the connecting sleeve 8, the drive cylinder 3 and the connecting rod 5 drive the support shaft 54 from the first section 62 to the second section 64. During this process, the support shaft 54 can lift the connecting sleeve 8 upwards, helping the connecting sleeve 8 to be fitted into the shaft hole 16 of the flange 11.
[0043] To prevent the support shaft 54 from scratching the connecting shaft, in this embodiment, reference is made to... Figure 4 The support shaft 54 passes through the fixing hole 52 of the connecting rod 5. The two ends of the support shaft 54 exposed on both sides of the fixing hole 52 are the first shaft part 55 and the second shaft part 56, respectively. The first shaft part 55 is located in the guide groove 61 and is slidably connected to the inner wall of the guide groove 61. The second shaft part 56 is fitted with a bushing 57, which cooperates with the contact surface 85.
[0044] Understandably, with this configuration, the first shaft 55 moves along the guide groove 61, and the second shaft 56 is rolled to the contact surface 85 via the bushing 57, reducing the friction between the support shaft 54 and the contact surface 85 and preventing scratches on the contact surface 85.
[0045] To ensure that the support shaft 54 can move below the contact surface 85 of the connecting sleeve 8, in this embodiment, reference is made to... Figure 4 The connecting rod 5 includes two symmetrically arranged connecting arms 51, each of which is fitted with a support shaft 54, and a bayonet 53 is formed between the two connecting arms 51 to avoid the connecting sleeve 8.
[0046] Understandably, with this setup, the two support shafts 54 need to be moved to a position where the line connecting the two support shafts 54 passes through the axis of the connecting sleeve 8 in order to better support the connecting sleeve 8 and prevent the connecting sleeve 8 from tilting during the clamping process with the tool holder 7 and flange 11. Through the clearance of the bayonet 53, it can be ensured that the connecting rod 5 can drive the two support shafts 54 to the specified position without colliding with the connecting sleeve 8.
[0047] To automatically detect whether the connecting sleeve 8 and flange 11 are properly assembled, in this embodiment, reference is made to... Figure 6 The drill bushing bracket 1 and the flange 11 are provided with a connected detection air passage 14. The detection air passage 14 has a detection hole 15 exposed on the inner wall of the shaft hole 16 of the flange 11, which mates with the assembly surface 82.
[0048] Understandably, with this setup, when the connecting sleeve 8 is not assembled into the shaft hole 16, the detection hole 15 is unobstructed, and air leaks continuously, resulting in low air pressure in the detection air passage 14. Once the connecting sleeve 8 is properly assembled, the assembly surface 82 blocks the detection hole 15, preventing or minimizing air leakage and increasing the air pressure in the detection air passage 14. The air pressure value in the detection air passage 14 can then be used to determine whether the connecting sleeve 8 and flange 11 are properly assembled. Furthermore, by detecting the position of the piston rod of the drive cylinder 3, it can be determined whether the support shaft 54 has moved into position within the guide groove 61, thus confirming whether the connecting sleeve 8 and flange 11 are properly assembled.
[0049] To facilitate the separation of the connecting sleeve 8 from the tool holder 7, in this embodiment, reference is made to... Figure 5 Assembly surface 82 is a conical surface.
[0050] Understandably, with this configuration, the mounting surface 82 is a conical surface, which facilitates the alignment of the connecting sleeve 8 with the flange 11 shaft hole 16 and guides the connecting sleeve 8 to be fitted into the shaft hole 16. At the same time, when the spindle 102 drives the tool holder 7 upward away from the connecting sleeve 8, the flange 11 is limited by the inner wall of the shaft hole 16 and the mounting surface 82, preventing the connecting sleeve 8 from moving upward. This allows the spindle 102 to drive the tool holder 7 to be pulled out of the connecting sleeve 8, leaving the connecting sleeve 8 and the guide sleeve 9 on the flange 11.
[0051] To reduce manufacturing costs, in this embodiment, reference is made to... Figure 1 and Figure 5 The connecting sleeve 8 has a central hole 87 on its shaft that communicates with the assembly hole 81, and the guide sleeve 9 is installed in the central hole 87.
[0052] Understandably, with this design, the guide sleeve 9 is a consumable part, and different diameter drill bits require guide sleeves 9 with different inner diameters. If the guide sleeve 9 and the connecting sleeve 8 are machined as a single piece, when the guide sleeve 9 wears out and becomes unusable, the connecting sleeve 8 also needs to be discarded along with the guide sleeve 9, resulting in significant waste. By machining the guide sleeve 9 and the connecting sleeve 8 separately, with the connecting sleeve 8 as a general-purpose part and the guide sleeve 9 as a special-purpose part, when the guide sleeve 9 wears out and becomes unusable, a new guide sleeve 9 can be replaced, while the connecting sleeve 8 can continue to be used, reducing manufacturing and maintenance costs.
[0053] In the specific working process of this application, before tool changing, the tool, connecting sleeve 8, and guide sleeve 9 are placed together in the tool magazine. The connecting sleeve 8 is fitted into the tool holder 7, and the first ball bearing 84 of the connecting sleeve 8 is engaged in the first slot 71 of the tool holder 7. During tool changing, the tool and connecting sleeve 8 are moved onto the spindle 102 together. Then, the drill sleeve bracket 1 descends, causing the connecting sleeve 8 to move into the shaft hole 16 of the flange 11. At the same time, the lifting assembly 2 reaches the height of the connecting sleeve 8. Then, the drive cylinder 3 drives the support shaft 54 to move along the guide groove 61. When the support shaft 54 moves to contact the contact surface 85 of the connecting sleeve 8, the support shaft 54 pushes the connecting sleeve 8 upward, and the drill bushing bracket 1 drives the flange 11 to move downward a certain height, so that the second ball bearing 12 is engaged in the second slot 83. After the connecting sleeve 8 and the flange 11 are engaged, the spindle 102 drives the tool to move upward. Under the limit of the assembly surface 82 and the shaft hole 16 of the flange 11, the tool holder 7 separates from the connecting sleeve 8, and the connecting sleeve 8 remains in the flange 11. After the tool change is completed, the guide sleeve 9 and the tool can perform deep hole drilling. When changing tools after deep hole drilling is completed, the drill sleeve bracket 1 will move the connecting sleeve 8 to the tool holder 7. The support shaft 54 needs to lift the connecting sleeve 8. Then the spindle 102 will drive the tool holder 7 downward into the assembly hole 81 of the connecting sleeve 8 until the first ball bearing 84 is stuck in the first slot 71. Then the drive cylinder 3 will drive the support shaft 54 to move backward. The spindle 102 will continue to drive the tool holder 7 to push the connecting sleeve 8 out of the shaft hole 16, so that the connecting sleeve 8 is separated from the flange 11. The connecting sleeve 8 will remain on the tool and will be changed into the tool magazine along with the tool.
[0054] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
