Technical Field

[0001] The embodiments of this utility model relate to the field of boring processing technology, specifically, to a horizontal boring processing equipment. Background Technology

[0002] In traditional boring machine equipment, the tool mounting method often adopts an integrated fastening structure, which makes the tool disassembly and replacement process cumbersome. In actual production, operators often need to use various specialized tools to complete the tool disassembly and replacement, increasing the operator's labor intensity and labor costs. Moreover, frequent disassembly operations can easily cause wear on the tool mounting parts of the equipment, reducing the service life of the equipment and the stability of machining accuracy. In addition, due to the low tool replacement efficiency, in scenarios where the product processing technology requires frequent tool changes, the equipment downtime increases, affecting production progress and processing efficiency. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this utility model provide a horizontal boring machine, which solves the technical problem that the tool disassembly and replacement process is cumbersome and increases the labor intensity of operators in related technologies.

[0005] The mounting bracket is mounted on the disc frame and moves radially along the rotation of the disc frame. A tool holder is mounted on the mounting bracket and is used to hold a tool. The mounting bracket rotates with the disc frame and drives the tool holder to rotate synchronously. After the mounting bracket moves, the tool holder and the tool rotate concentrically or eccentrically relative to the disc frame.

[0006] The material feeding push rod is movable on the disc frame along the rotation axis of the disc frame and rotates with the disc frame. The material feeding push rod is located on one side of the movement path of the tool holder. After the material feeding push rod moves, it can push the tool to disengage from the tool holder.

[0007] A rotation drive assembly is used to drive the disk frame to rotate.

[0008] For example, in a horizontal boring machine provided by at least one embodiment of the present invention, the tool holder is provided with a mounting hole through the axis, the tool holder is used to install the tool shank in the mounting hole, and the tool clamp is provided in the mounting hole for clamping and fixing the periphery of the tool shank.

[0009] The tool holder is configured such that, after being moved, the unloading push rod aligns with or dealigns with the mounting hole, extends into the mounting hole, and pushes the tool holder away from the tool clamp.

[0010] For example, in a horizontal boring machine provided in at least one embodiment of the present invention, a pusher is provided, which is movably disposed on the machine tool along the axis and is used to push the blanking push rod to move towards the tool holder.

[0011] For example, in a horizontal boring machine provided in at least one embodiment of the present invention, the pusher is annular and its axial sidewall can cover the rotation path of the feeding push rod.

[0012] For example, in a horizontal boring machine provided by at least one embodiment of the present invention, a linear drive is provided. The linear drive is disposed in the machine tool and located on the side of the pusher away from the unloading push rod. The linear drive is used to push the pusher to move.

[0013] For example, in a horizontal boring machine provided by at least one embodiment of the present invention, there are two linear drive members, and the drive ends of the two linear drive members are respectively connected to the upper and lower sides of the push member.

[0014] For example, in at least one embodiment of the present invention, a horizontal boring machine includes a rotation drive assembly comprising:

[0015] A first rotating shaft is rotatably mounted on the machine tool, connected to the disc frame, and drives the disc frame to rotate. The first rotating shaft has a first shaft hole that extends through it along its axial direction.

[0016] The second rotating shaft is disposed in the first shaft hole;

[0017] A main bevel gear, which is mounted on the second rotating shaft;

[0018] A lead screw is rotatably mounted on the disc frame, with its length direction parallel to the rotational radial direction of the disc frame. The lead screw rotates with the disc frame, and the mounting bracket is threadedly connected to the lead screw.

[0019] A secondary bevel gear is mounted on the lead screw and meshes with the primary bevel gear.

[0020] For example, in a horizontal boring machine provided in at least one embodiment of the present invention, the feed pusher is located on one side of the lead screw.

[0021] For example, in at least one embodiment of the present invention, a horizontal boring machine further includes: a first drive motor for driving the second rotating shaft to rotate;

[0022] The rotation drive assembly further includes:

[0023] The first gear is disposed on the circumference of the first rotating shaft;

[0024] The second gear is rotatably mounted on the machine tool and meshes with the first gear.

[0025] The second drive motor is used to drive the second gear to rotate.

[0026] For example, in a horizontal boring machine provided by at least one embodiment of the present invention, the disc frame has two slide rails, which are respectively located on both sides of the rotational radial direction of the disc frame, and the mounting bracket is slidably disposed on the two slide rails.

[0027] The beneficial effects of the embodiments of this utility model are as follows:

[0028] In this invention, the design of the feed pusher solves the problem of difficult tool disassembly and replacement in traditional boring equipment.

[0040] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] like Figure 1 As shown, this invention discloses a horizontal boring machine. The disc frame 2 serves as the carrier for components such as the mounting bracket 3, and its rotation causes the cutting tool 11 to rotate accordingly for boring. The rotation drive assembly 6 typically consists of a motor and a transmission mechanism (such as belt drive or gear drive). When the motor is energized, it generates power, which is transmitted to the disc frame 2 via the transmission mechanism, causing the disc frame 2 to rotate at a set speed and direction. The mounting bracket 3 can move along the radial direction of the disc frame 2. When the mounting bracket 3 moves to the center position of the disc frame 2, the tool holder 4 and the cutting tool 11 mounted on the tool holder 4 will rotate concentrically relative to the disc frame 2; when the mounting bracket 3 moves radially in the disc frame 2, the tool holder 4 and the cutting tool 11 will rotate eccentrically relative to the disc frame 2. During the rotation of the disc frame 2, the mounting bracket 3 rotates along with the disc frame 2, simultaneously driving the tool holder 4 and the cutting tool 11 to rotate synchronously. During boring, the tool 11 performs the boring operation on the workpiece as the mounting bracket 3 and the disc holder 2 rotate. By adjusting the radial position of the mounting bracket 3, different processing requirements can be met, improving the processing adaptability and versatility of the equipment and satisfying the diverse processing needs of different types of workpieces. No equipment replacement or complex adjustments are required, thus improving production efficiency and reducing production costs.

[0042] The unloading push rod 5 is mounted on the disc frame 2 and rotates along with it. When the unloading push rod 5 needs to work, it moves along the rotation axis of the disc frame 2. Because it is located on one side of the movement path of the tool holder 4, when it reaches the appropriate position, the unloading push rod 5 can push the tool 11 mounted on the tool holder 4, causing it to disengage from the tool holder 4 and completing the unloading operation of the tool 11. The unloading push rod 5 solves the problem of the tool 11 being difficult to disassemble and replace in traditional boring equipment. By moving the unloading push rod 5 axially, the tool 11 can be pushed out of the tool holder 4, simplifying the disassembly process of the tool 11, saving the time of tool 11 replacement, and improving production efficiency.

[0043] like Figure 4As shown, in some examples, the shank of the tool 11 is inserted into the mounting hole 401, which is provided along the axis of the tool holder 4. At this time, the grippers 402 in the mounting hole 401 automatically clamp the circumference of the shank, fixing it within the mounting hole 401 through elastic clamping force. During boring, the tool holder 4 rotates together with the mounting frame 3 and the disc holder 2, thereby rotating the tool 11 mounted thereon to perform boring operations on the workpiece. When it is necessary to change the tool 11, the tool holder 4 can be moved to a suitable position, aligning the blanking push rod 5 with the mounting hole 401. The blanking push rod 5 moves along the rotation axis of the disc holder 2, extending into the mounting hole 401. The end of the blanking push rod 5 contacts the shank of the tool 11, and then continues to apply a pushing force, overcoming the clamping force of the grippers 402 on the shank, pushing the shank out of the grippers 402, thus disengaging the tool 11 from the tool holder 4 and completing the blanking operation of the tool 11. When no unloading operation is required, the tool holder 4 moves, causing the unloading push rod 5 to dealign with the mounting hole 401. The unloading push rod 5 will not affect the tool 11, and the tool 11 can perform normal machining operations. In this solution, if... Figure 4 The diagram shows the BT50 and its commonly used grippers.

[0044] The design of aligning and dealigning the unloading push rod 5 with the mounting hole 401 enables control over the disassembly of the tool 11. The unloading push rod 5 aligns with the mounting hole 401 only when tool 11 needs to be disassembled, avoiding interference with the tool 11 during processing and ensuring the stability of the machining process. This structural design makes the disassembly process of the tool 11 more automated and convenient, eliminating the need for manual disassembly, reducing the labor intensity of operators, improving the efficiency of tool 11 replacement, and thus increasing the overall production efficiency of the equipment.

[0045] like Figure 1 and Figure 2 As shown, in some examples, the pusher 7 is positioned along the axis of the machine tool 1 and is axially movable. When it is necessary to push the unloading push rod 5 towards the tool holder 4 to disassemble the tool 11, the pusher 7 begins to operate. Under the action of a power source (such as hydraulic, pneumatic, or electric drive), the pusher 7 moves towards the unloading push rod 5 along its axial direction. After the pusher 7 contacts the unloading push rod 5, it continues to apply a pushing force, causing the unloading push rod 5 to also move towards the tool holder 4. Once the unloading push rod 5 moves to align with and inserts into the mounting hole 401 of the tool holder 4, it can push the tool holder of the tool 11 to disengage from the gripper 402, completing the disassembly operation of the tool 11. When tool 11 disassembly is not required, i.e., when the unloading push rod 5 is not needed, the pusher 7 remains in its initial position or returns to its corresponding non-working position, not contacting the unloading push rod 5, to avoid affecting the normal processing operation of the equipment.

[0046] like Figure 1 and Figure 2 As shown, in some examples, the pusher 7 and the unloading push rod 5 are not connected to each other and are relatively independent, which makes their relative movement more flexible. The unloading push rod 5 can freely follow the rotation of the disc frame 2 without being constrained by the pusher 7. The annular structure of the pusher 7 and its axial sidewall cover the rotation path of the unloading push rod 5, so that the pusher 7 can always maintain contact with the unloading push rod 5 after moving and push it to move, which improves the versatility and adaptability of the equipment.

[0047] like Figure 1 As shown, in some examples, the linear drive 8 is installed inside the machine tool 1 and is located on the side of the pusher 7 away from the unloading push rod 5. The linear drive 8 can be a drive device of the type of electric lead screw, hydraulic cylinder, pneumatic cylinder, etc. The linear drive 8 is located inside the machine tool 1, which does not occupy too much external space, making the overall structure of the equipment more compact.

[0048] like Figure 1 As shown, in some examples, two linear drive members 8 are connected to the upper and lower sides of the pusher 7 respectively, which can apply the thrust evenly and prevent the pusher 7 from tilting or deviating during movement. Compared with a single linear drive member 8, this structure can better ensure that the pusher 7 moves linearly along the predetermined axis, improve the stability and accuracy of the pusher 7's movement, and thus ensure that the unloading pusher 5 can be accurately aligned with the mounting hole 401 of the tool holder 4, and smoothly complete the disassembly operation of the tool 11.

[0049] Because the pusher 7 is acted upon by the linear drive 8 on both its upper and lower sides, the force is more evenly distributed, reducing localized wear caused by uneven force distribution. Simultaneously, it reduces the risk of damage to components connected to the pusher 7 (such as the feeding push rod 5) due to unbalanced force, extending the service life of all equipment components and lowering maintenance costs. Even if one linear drive 8 fails, the other may still provide some thrust, enabling the pusher 7 to complete some movement or at least move it to a safe position, preventing the equipment from becoming completely inoperable due to a single drive failure. This redundant design improves equipment reliability and safety, reduces downtime, and ensures production continuity.

[0050] like Figure 1 and Figure 2As shown, in some examples, the first rotating shaft 601 is rotatably mounted on the machine tool 1 and connected to the tray 2. When the rotation drive assembly 6 starts working, the power source (e.g., a motor) transmits power to the first rotating shaft 601, causing the first rotating shaft 601 to rotate about its own axis on the machine tool 1. Since the first rotating shaft 601 is connected to the tray 2, the rotation of the first rotating shaft 601 drives the tray 2 to rotate synchronously, providing rotational power for components such as the mounting bracket 3, tool holder 4, and cutting tool 11 mounted on the tray 2, enabling them to perform the circumferential motion required for boring.

[0051] The main bevel gear 602 is fixedly mounted on the second rotating shaft 9 and rotates with the second rotating shaft 9. The teeth of the main bevel gear 602 are conical, and when it rotates, it can transmit the rotational direction and motion of the rotating shaft to the meshing secondary bevel gear 604. When the rotating shaft drives the main bevel gear 602 to rotate, the teeth of the main bevel gear 602 mesh with the teeth of the secondary bevel gear 604, thereby transmitting the rotational power to the secondary bevel gear 604, realizing the change of rotational direction and the transmission of power.

[0052] The lead screw 603 is rotatably mounted on the disc frame 2, with its length direction parallel to the rotational radial direction of the disc frame 2, and it can rotate with the disc frame 2. The secondary bevel gear 604 makes circular motion around the main bevel gear 602. When the mounting frame 3 does not need to be moved and its position is kept constant, the rotational angular velocity of the main bevel gear 602 and the revolution angular velocity of the secondary bevel gear 604 around the main bevel gear 602 are consistent, so that the main bevel gear 602 and the secondary bevel gear 604 maintain meshing while not rotating relative to each other to transmit power.

[0053] When it is necessary to move the mounting bracket 3 and change the rotation radius of the tool 11, the rotation speed of the second rotating shaft 9 can be increased, thereby increasing the rotational angular velocity of the main bevel gear 602. At this time, the rotational angular velocity of the main bevel gear 602 is greater than the revolution angular velocity of the secondary bevel gear 604 around the main bevel gear 602, causing the main bevel gear 602 and the secondary bevel gear 604 to rotate relative to each other. This drives the secondary bevel gear 604 to rotate, and after the secondary bevel gear 604 rotates, it drives the lead screw 603 to rotate synchronously, allowing the mounting bracket 3 to move along the rotational radial direction of the disc holder 2. This enables the tool holder 4 and the tool 11 to switch between different machining states of concentric or eccentric rotation relative to the disc holder 2. This can meet the requirements of different machining processes for the position of the tool 11, improving the machining accuracy and adaptability of the equipment.

[0054] like Figure 3As shown, in some examples, the feeding pusher 5 is located on one side of the lead screw 603, and the two cooperate spatially in the overall layout of the equipment. When the mounting bracket 3 moves radially under the drive of the lead screw 603, the feeding pusher 5 will not interfere with it, ensuring the smooth movement of the mounting bracket 3. At the same time, when the feeding pusher 5 performs the action of pushing the cutter 11, it will not be obstructed by the lead screw 603 and its related components, and can smoothly reach the position of the cutter holder 4 to complete the disassembly task of the cutter 11. Furthermore, at each stage of equipment operation, the feeding pusher 5 and the lead screw 603 can work normally in their respective working areas without interfering with each other, making the layout of the entire equipment more reasonable, reducing the equipment's footprint, and improving the space utilization rate of the workshop.

[0055] In some examples, the second shaft 9 is driven to rotate by an independent first drive motor 10. The outer periphery of the first shaft 601 is provided with a first gear 605. After the first gear 605 rotates, it can drive the first shaft 601 to rotate synchronously. Specifically, the second drive motor 607 drives the second gear 606 to rotate. Through the meshing of the second gear 606 with the first gear 605, the first gear 605 is driven to rotate.

[0056] like Figure 3 As shown, in some examples, two slide rails 201 are located on both sides of the rotational radial direction of the disc frame 2. Compared with a single slide rail 201, this double-sided slide rail 201 design can better limit the swing and offset of the mounting frame 3 during the movement, so that the mounting frame 3 can move more stably along the radial direction of the disc frame 2, thereby accurately adjusting the position of the tool 11 and improving the accuracy of boring.

[0057] When the platen 2 rotates for machining, the mounting frame 3, tool holder 4, and tool 11 generate significant centrifugal forces and other forces. The two slide rails 201 can evenly distribute these forces, improving the load-bearing capacity of the entire structure and ensuring that the mounting frame 3 will not be damaged due to uneven force during high-speed rotation, thus extending the service life of the equipment.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
