Description

Technical Field

[0001] The present invention relates to the technical field of boring processing equipment, in particular to a horizontal boring processing equipment. Background Art

[0002] In the field of modern mechanical processing, horizontal boring equipment, as the core equipment for high-precision hole processing, is widely used in high-end manufacturing industries such as aerospace, automobile manufacturing, and mold processing. The tool magazines equipped with traditional horizontal boring processing equipment mostly adopt a disc-type structure design, which realizes the tool selection action by rotating around the central axis. In actual application, after the operator issues a tool change command, the tool magazine control system drives the disc-type tool magazine to rotate. After the target tool is rotated to the preset tool change position, the tool magazine stops rotating. However, since the disc-type tool magazine usually stores tools in the axial direction, when the target tool reaches the change position, an independent rotation mechanism must be installed on the outside of the tool magazine to swing the tool from an axial posture to extend radially outward along the tool magazine for subsequent robotic arm grasping. The independent rotation mechanism usually includes a servo motor, a transmission gear set and a complex positioning and locking device, which increases the mechanical complexity of the tool magazine and occupies a certain amount of equipment space, thereby affecting the overall processing accuracy and equipment reliability. Summary of the Invention

[0003] In order to overcome the above-mentioned defects, the present invention provides a horizontal boring processing equipment, which solves the technical problem in the related technology that the independent rotating mechanism installed on the outside increases the mechanical complexity of the tool magazine, occupies a certain equipment space, and thus affects the overall processing accuracy and equipment reliability.

[0004] According to one aspect, at least one embodiment of the present invention provides a horizontal boring processing device, comprising: a base, a first tool magazine rotatably disposed on the base, a plurality of circumferentially spaced mounting seats provided on the outer periphery of the first tool magazine, a first placement slot formed between two adjacent mounting seats; A plurality of first tool seats are provided and are located in the first placement groove in a one-to-one correspondence. The first tool seats are used to store tools. The first tool seats are rotatably connected to two adjacent mounting seats via a first rotating shaft. The end of the first rotating shaft is provided with a rotating disk that rotates with the mounting seat; Among them, the first tool holder can drive the tool to swing under the action of the turntable, so that the tool swings to the first storage position extending axially along the first tool magazine. The first tool holder can also drive the tool to swing to the tool replacement position extending radially along the first tool magazine outside the first placement slot under the action of the turntable, so as to supply the tool to the boring processing table.

[0005] For example, in a horizontal boring machining device provided by at least one embodiment of the present invention, an installation cavity is provided on the end face of the first tool magazine facing away from the base table. The installation cavity is coaxially arranged with the first tool magazine. A second tool magazine is rotatably arranged in the installation cavity. A plurality of second placement grooves are provided on the peripheral wall of the second tool magazine. The second tool magazine can rotate relative to the first tool magazine so that the second placement grooves are radially corresponding and communicated with the first placement grooves. The first tool holder can drive the tool to swing under the action of the turntable so that the tool swings to a second storage position extending radially along the first tool magazine into the second placement groove.

[0006] For example, in a horizontal boring machining device provided by at least one embodiment of the present invention, a second tool holder for storing tools is movably arranged in the second placement groove. The second tool holder can slide along the radial direction of the second tool magazine to approach or move away from the main shaft of the second tool magazine.

[0007] For example, in a horizontal boring machining device provided by at least one embodiment of the present invention, a first track extending tangentially is provided on the turntable. Radially extending second tracks are provided on both side walls of the second placement groove; The first track can be collinear with the second track under the drive of the rotation of the turntable; Wherein, support seats are respectively arranged on both sides of the second tool holder. The support seats are movably arranged on the second tracks. When the first track and the second track are collinear, the second tool holder can move onto the first track so that the tool carried by the second tool holder can rotate following the turntable and extend outside the first placement groove.

[0008] For example, in a horizontal boring machining device provided by at least one embodiment of the present invention, the support seat is connected to the second tool holder through a second rotating shaft (17). A first rotation driving part for driving the second rotating shaft (17) to rotate to drive the second tool holder and the tool carried by the second tool holder to rotate synchronously is provided on the support seat.

[0009] For example, in a horizontal boring machining device provided by at least one embodiment of the present invention, the first track and the first rotating shaft are located on both sides of the central axis of the turntable. The second tool holder can move onto the first track and is symmetrically located on both sides of the central axis of the turntable with the first tool holder.

[0010] For example, in a horizontal boring machining device provided by at least one embodiment of the present invention, when the turntable drives the first track to rotate to be collinear with the second track, there is a gap between the second track and the first track so that the second track can avoid interfering with the first track when following the turntable to rotate.

[0011] For example, in a horizontal boring and milling machine provided by at least one embodiment of the present invention, both the first track and the second track are racks. A driving assembly for driving the second tool holder to move along the first track or the second track is provided on one of the support seats. The driving assembly includes a second rotary driving member, a first gear, and a second gear rotatably connected to the support seat. The first gear and the second gear are arranged at intervals along the extending direction of the second track. The first gear and the second gear can be driven by the second rotary driving member to rotate, so that the two support seats and the second tool holder move synchronously along the first track and / or the second track.

[0012] For example, in a horizontal boring and milling machine provided by at least one embodiment of the present invention, a main gear is further rotatably provided on the second support seat. The second rotary driving member is connected to the main gear and is used to drive the main gear to rotate. The main gear is arranged between the first gear and the second gear and meshes with the first gear and the second gear.

[0013] For example, in a horizontal boring and milling machine provided by at least one embodiment of the present invention, an installation groove is provided on the side wall of the installation seat. The turntable is rotatably arranged in the installation groove, and a third rotary driving member for driving the turntable to rotate is provided in the installation groove.

[0014] The beneficial effects of the embodiments of the present invention are as follows: In the present invention, when replacement is required, only the rotary driving member installed inside the side wall of the first placement groove is used to drive the turntable to rotate. After the turntable rotates, it will drive the first tool holder to revolve around the turntable rotating shaft. Since the first tool holder and the turntable are fixedly connected, when the first tool holder revolves, the cylindrical tool holder and the tool carried by it will follow the rotation until it is parallel to the radial direction of the first tool magazine and outward. At this time, it is at the tool replacement position, and the tool will extend out of the first tool magazine to the outside, and the robot arm will grab and replace it.

[0015] The rotary driving member is hidden inside the side wall of the first placement groove and does not occupy external space. Preferably, a window for placing, inspecting, and maintaining the rotary driving member is further provided on the first tool magazine. Compared with the traditional independently arranged rotating mechanism, directly arranging the turntable on the side wall of the first placement groove reduces the space occupied by the independent rotating mechanism, simplifies the equipment structure, reduces the equipment manufacturing and maintenance costs, and improves the stability and accuracy of tool posture adjustment at the same time.

Detailed implementation manners

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention.

[0020] To make the drawings concise, only the parts related to the invention are schematically shown in each drawing, and they do not represent the actual structure of the product. In addition, to make the drawings concise and easy to understand, in some drawings, components with the same structure or function are only schematically shown for one of them, or only one of them is marked. In this article, "one" not only means "only this one", but also means "more than one" situation, and "several" includes "two" and "more than two".

[0021] In this article, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] In the present invention, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them.

They are only for convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0024] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0025] As Figures 1 to 12 shown, it shows a horizontal boring machining device in an embodiment of the present invention. A first tool magazine 2 is rotatably arranged on a base 1. A plurality of circumferentially spaced mounting seats 203 are provided on the outer periphery of the first tool magazine 2. A first placement groove 201 is formed between two adjacent mounting seats 203. Mounting grooves 204 for mounting a turntable 4 are provided on the two side walls of the first placement groove 201. The turntable 4 is rotatably arranged in the mounting groove 204. The two turntables 4 on the two side walls of the first placement groove 201 are symmetrically distributed. The first tool holder is rotatably connected to two adjacent mounting seats through a first rotating shaft. Among them, the first tool holder 5 and the first rotating shaft 15 are fixedly connected, and are only connected to the turntable 4 on the mounting seat 203 through the first rotating shaft 15. After the turntable 4 rotates, it can drive the first tool holder 5 to rotate around the turntable 4 (revolve or rotate, that is, the first rotating shaft 15 and the turntable 4 are coaxial or eccentric), so as to adjust the position and attitude of the tool. In this solution, referring to Figure 6 , the first rotating shaft 15 is eccentrically arranged relative to the turntable 4.

[0026] Specifically, taking the first tool holder 5 located at the first storage position 101 as the initial state, in this solution, the component of the first tool holder 5 for fixing the tool is a conventional cylindrical tool holder. In the initial state, the cylindrical tool holder is arranged along the axial direction of the first tool magazine 2. At this time, the tool placed in the cylindrical tool holder is also axially arranged; When replacement is needed, only the third rotation driving member 16 installed inside the side wall of the first placement groove 201 is used to drive the turntable 4 to rotate. After the turntable 4 rotates, it will drive the first tool holder 5 to revolve around the rotating shaft of the turntable 4. Since the first tool holder 5 and the turntable 4 are fixedly connected, when the first tool holder 5 revolves, the cylindrical tool holder and the tool it carries will rotate accordingly until it is parallel to the radial direction of the first tool magazine 2 and extends outward, such as the state of the second tool holder 8 shown in Figure 7 . At this time, it is located at the tool replacement position 102, and the tool will extend out of the first tool magazine 2 to the outside, and the robotic arm will perform grasping and replacement. In the arrangement where the first rotating shaft 15 and the turntable 4 are coaxial, the operation process is similar to the above and will not be elaborated.

[0027] The third rotation driving member 16 is hidden inside the mounting base 203, without occupying external space. As an optimization, a window 205 for placing, inspecting, and repairing the third rotation driving member 16 is also provided on the first tool magazine 2. This reduces the space occupied by the independent rotation mechanism, simplifies the equipment structure, reduces the equipment manufacturing and maintenance costs, and improves the stability and accuracy of tool posture adjustment at the same time.

[0028] In some examples, such as Figures 2 to 4 shown, a second tool magazine 7 is coaxially rotatably arranged in the installation cavity 202 of the first tool magazine 2. Among them, the first tool magazine 2 and the second tool magazine 7 remain coaxial and there are various ways to achieve relative rotation. In this solution Figure 10 a driving method is provided for reference, that is, the main shaft 13 passes through the first tool magazine 2 and then is connected to the second tool magazine 7 to drive the second tool magazine 7 to rotate. The sleeve shaft 14 is located on the circumferential outer side of the main shaft 13 and is connected to the first tool magazine 2. The sleeve shaft 14 is used to drive the first tool magazine 2 to rotate. A gear can be provided on the sleeve shaft 14 for transmission, and a gear transmission can also be provided on the main shaft 13, which can be carried out according to the actual factory situation.

[0029] Such as Figure 3 shown, at least one second placement groove 701 for storing tools is provided on the circumferential side of the second tool magazine 7. When the second tool magazine 7 rotates and the second placement groove 701 communicates with the first placement groove 201, the second placement groove 701 can cooperate with the first placement groove 201 to jointly accommodate the tools on the first tool holder 5. It should be noted that in this state, since the tool extends from the first placement groove 201 into the second placement groove 701, it is necessary to keep the first tool magazine 2 and the second tool magazine 7 rotating synchronously.

[0030] Specifically, driven by the turntable 4, the first tool holder 5 can not only be adjusted to the first storage position 101 and the tool replacement position 102, but also revolve around the axis of the turntable 4, so that the tool is arranged parallel to the radial direction of the first tool magazine 2 and extends into the second placement groove 701. At this time, the first tool holder 5 and the tool carried by it are completely incorporated into the radially arranged and communicating first placement groove 201 and second placement groove 701, that is, the second storage position 103. This enables the longer tool not to extend along the axial direction of the equipment. The first placement groove 201 that is not connected to the second placement groove 701 can place shorter tools or no tools, greatly reducing the space occupied by the equipment in the axial direction. For processing scenarios where the factory building space is limited or multiple equipment needs to be installed in a narrow space, this design effectively reduces the equipment's demand for axial space and improves the utilization rate of the workshop space; at the same time, the compact axial dimension also facilitates the transportation and installation of the equipment, reducing the space limitation and installation difficulty during transportation.

[0031] In some examples, such as Figure 5As shown, the second tool holder 8 moves radially along the second tool magazine 7 within the second placement groove 701. The driving force for its movement can be achieved by a linear driving device (such as a linear motor, a cylinder, a rack and pinion, etc.). The second placement groove 701 provides guidance and constraint for the movement of the second tool holder 8. It is internally designed with a track or chute structure that matches the movement mechanism of the second tool holder 8 to ensure the stability and accuracy of the second tool holder 8 during radial movement.

[0032] When the tools on the second tool holder 8 are arranged axially for storage, by moving the second tool holder 8 to adjust the interval from the first tool holder 5, interference and collision during the process of tool picking and placing can be avoided, providing sufficient operating space for the robotic arm or other tool picking devices, and improving the safety and efficiency of tool picking and placing.

[0033] When the tools on the second tool holder 8 are arranged radially for storage, as Figures 4 to 7 shown, the second tool holder 8 can change the interval from the bottom of the groove through radial movement, which can adapt to the storage requirements of tools with different lengths, improving the compatibility of the tool magazine with tools and reducing the tool management cost and complexity of the equipment.

[0034] In some examples, the first track 401 is tangent to the turntable 4. When the turntable 4 rotates, the first track 401 rotates synchronously with the turntable 4. Its function is to dock with the second track 702 to form an accessible movement path, as Figure 6 shown, providing guidance for the transfer of the second tool holder 8 from the second placement groove 701 to the turntable 4. The second track 702 extends radially along the two side walls of the second placement groove 701, providing guidance for the radial movement of the second tool holder 8 within the second placement groove 701. When the second tool holder 8 is located on the second track 702, the radial position adjustment of the tool can be achieved; when it moves to the first track 401, the angular position adjustment is achieved by rotating with the turntable 4.

[0035] As Figure 5 shown, specifically, in the initial state, the first tool holder 5 is located at the first storage position 101, and the second tool holder 8 is located at the initial position within the second placement groove 701. The third rotation driving member 16 drives the turntable 4 to rotate, rotating the first tool holder 5 and its tool to one side that is axisymmetric with respect to the turntable 4. At this time, the first track 401 and the second track 702 are collinear, as Figure 6 shown. The second rotation driving member 1003 drives the first gear 1001 and the second gear 1002 to rotate, thereby driving the second tool holder 8 to move along the second track 702 towards the first track 401, entering the first track 401 after passing through the track docking point, and finally driving the second tool holder 8 to the first storage position 101. Further, the turntable 4 rotates, rotating the second tool holder 8 and the carried tool to the tool replacement position 102, as Figure 7 shown, so that the robotic arm can perform the next grasping step.

[0036] The tool replaced by the robotic arm is placed back into the second tool holder 8 located at the tool changing position 102. The turntable 4 rotates to turn the second tool holder 8 back to the first storage position 101. The second tool holder 8 moves along the first track 401 to the track docking location and then returns to its initial position within the second placement groove 701 along the second track 702. The turntable 4 further rotates to turn the first tool holder 5 back to the first storage position 101, and the system resumes its initial state, waiting for the next tool change command.

[0037] In some examples, such as Figure 6 and Figure 8 shown, one end of the second rotating shaft 17 is rotatably installed on one of the support seats 9, and the second tool holder 8 is fixedly connected thereto. The first rotating shaft 17 is provided with rotational drive by the first rotation drive member 6. The second tool holder 8 is fixedly installed on the second rotating shaft 17 and rotates with the second rotating shaft 17, enabling the tool to switch between two placement states, axial and radial, to adapt to different machining requirements and tool change processes.

[0038] The above solution aims to solve the following problem: When the tool on the second tool holder 8 is placed radially, that is, when the tool on the second tool holder 8 is located within the second placement groove 701, at this time, when the second tool holder 8 moves onto the first track 401, the tool remains in the radial placement state rather than the axial state, as Figure 6 shown. This results in that when the turntable 4 rotates to turn the tool on the second tool holder 8 to the tool changing position 102, the tool is arranged axially (the orientation of the tool holder is similar to the state of the first tool holder 5 in Figure 4 ), rather than radially, and the robotic arm cannot perform grasping and replacement.

[0039] However, when the tool on the second tool holder 8 is placed axially, the above problem will not occur.

[0040] Taking the above problem scenario as an example, it is as follows: The first tool holder 5 is located at the first storage position 101, the second tool holder 8 is within the second placement groove 701, its support seat 9 is at the initial position of the second track 702, and the tool within the second tool holder 8 is placed radially in the second placement groove 701. When it is necessary to retrieve the tool on the second tool holder 8, the third rotation drive member 16 first drives the turntable 4 to rotate, causing the first tool holder 5 and its tool to rotate away from the first storage position 101 and reach the side that is axisymmetric with respect to the axis of the turntable 4. At this time, the first track 401 rotates to the first storage position 101 and is collinear with the second track 702.

[0041] Such as Figure 7 and Figure 8As shown, the driving support base 9 moves along the second track 702 towards the first track 401 until the support base 9 completely enters the first track 401. At this time, the second tool holder 8 moves to the first storage position 101. The first rotation driving member 6 drives the second rotating shaft 17 to rotate, driving the second tool holder 8 to rotate, adjusting the tool originally placed radially to the same angle and position as the tool on the first tool holder 5 in the initial state, so that the tool is in a posture convenient for the robotic arm to grasp.

[0042] The turntable 4 continues to rotate, rotating the tool on the second tool holder 8 to the tool replacement position 102. The robotic arm accurately grasps and replaces the tool according to the preset program and positioning reference. The robotic arm places the replaced tool back into the second tool holder 8 located at the tool replacement position 102. The first rotation driving member 6 rotates in the reverse direction to drive the second rotating shaft 17, so that the second tool holder 8 returns to the initial angle (axial or radial). The support base 9 returns to the initial position of the second placement groove 701 along the first track 401 and the second track 702. The turntable 4 rotates to make the first tool holder 5 return to the first storage position 101, and the device returns to the initial state, waiting for the next tool change instruction.

[0043] In some examples, when the second tool holder 8 moves along the second track 702 to the first track 401 and is located on the turntable 4, its position is symmetrically distributed with respect to the axis (central axis) of the turntable 4 of the first tool holder 5. The symmetrical arrangement makes the movement trajectories of the second tool holder 8 and the first tool holder 5 coincide on the turntable 4. When they are respectively at the tool replacement position 102, the spatial coordinates (such as horizontal position, height, etc.) of the tools are the same. The robotic arm does not need to be recalibrated or adjust the program, and only needs a set of fixed positioning parameters to accurately grasp the tools on different tool holders, avoiding the risk of grasping failure or collision caused by position deviation.

[0044] In some examples, such as Figure 8As shown, a main gear 11, a first gear 1001, and a second gear 1002 are provided on one of the support seats 9. The main gear 11 is located between the first gear 1001 and the second gear 1002 and meshes with the first gear 1001 and the second gear 1002. The main gear 11 is driven to rotate by a second rotation driving member 1003. When the main gear 11 rotates, it drives the first gear 1001 and the second gear 1002 to rotate synchronously in opposite directions. Since the main gear 11 is located between the first gear 1001 and the second gear 1002, the rotation direction of the main gear 11 is opposite to the rotation directions of the first gear 1001 and the second gear 1002, and the rotation directions of the first gear 1001 and the second gear 1002 are the same, forming a stable power transmission. Both the first track 401 and the second track 702 are racks. Preferably, the radial interval between the first gear 1001 and the second gear 1002 is greater than the interval when the first track 401 and the second track 702 are collinear, ensuring that at least one gear is always meshed with the rack during the track switching process, avoiding power interruption.

[0045] Through the relay meshing design of the first gear 1001 and the second gear 1002, even at the track interval (the position where the two tracks are collinear but discontinuous), at least one gear can be ensured to remain in the meshed state, avoiding jamming or derailment when the second tool holder 8 moves, and ensuring the continuity of the movement.

[0046] By combining the meshing of the gears with different track racks, the movement of the second tool holder 8 in three states, namely "inside the second placement groove 701", "on the turntable 4", or "switching between tracks", can be controlled to meet the requirements of different working scenarios.

[0047] Specifically, in the initial state, that is, when the second tool holder 8 is located inside the second placement groove 701, both the first gear 1001 and the second gear 1002 mesh with the first track 401 of the first track 401. The main gear 11 is driven to rotate by the second rotation driving member 1003, driving the first gear 1001 and the second gear 1002 to rotate synchronously, so that the second tool holder 8 moves along the first track 401 inside the second placement groove 701 (such as tool storage or preliminary position adjustment).

[0048] When the second tool holder 8 needs to move onto the turntable 4, the main gear 11 continues to drive the first gear 1001 and the second gear 1002 to rotate. As the second tool holder 8 moves towards the track interval, the first gear 1001 first enters the track interval and temporarily disengages from the meshing. Since the distance between the first gear 1001 and the second gear 1002 is greater than the track interval, the second gear 1002 still meshes with the second track 702 of the second track 702 and drives the second tool holder 8 to continue moving alone, ensuring that the power is not interrupted.

[0049] When the second tool holder 8 further rises, the second gear 1002 enters the interval between the first track 401 and the second track 702 and disengages from the meshing; at this time, the first gear 1001 has crossed the interval and re-engages with the upper first track 401, and relays to drive the second tool holder 8 to move onto the turntable 4. At this time, the first gear 1001 and the second gear 1002 are switched to both engage with the second track 702, and the second tool holder 8 moves on the turntable 4 (such as rotating to the tool changing position 102 with the turntable 4).

[0050] During the transition stage at the track interval, there will be a short state where the first gear 1001 engages with the first track 401 and the second gear 1002 engages with the second track 702. At this time, the first gear 1001 and the second gear 1002 respectively cooperate with the racks of different tracks, and through the synchronous drive of the main gear 11, the smooth switching of the tool holder from the first track 401 to the second track 702 is realized, avoiding the position deviation caused by the track interruption.

[0051] When the second tool holder 8 needs to return from the turntable 4, the main gear 11 reversely drives the first gear 1001 and the second gear 1002, repeating the above-mentioned relay meshing process: the second gear 1002 first engages with the second track 702 to drive the movement, and after entering the interval, the first gear 1001 relays to engage with the first track 401, finally returning the second tool holder 8 to the initial track position. Ensure the smooth movement and precise positioning of the second tool holder 8 between different working areas (placement groove, turntable 4), improving the processing efficiency and reliability of the equipment.

[0052] As a preference, as Figure 8 shown, two gears can also be rotatably arranged on another support base 9. Due to the self-locking property between the gear and the rack, when the second tool holder 8 moves onto the turntable 4, the meshing effect between the gear and the first track 401 is used to improve the stability of the second tool holder 8 during the movement and the tool picking and placing process. In some examples, the first tool magazine 2 is of a disc-shaped structure, and a plurality of first placement grooves 201 are uniformly spaced along the circumferential direction on its circumferential wall. Drive mechanisms for the turntable 4 are installed on both side walls of each first placement groove 201, which are used to carry the first tool holder 5 and adjust the tool posture (axial storage or radial tool changing position). The second tool magazine 7 is coaxially nested inside the first tool magazine 2 in the radial direction, and a plurality of second placement grooves 701 are spaced along the circumferential direction on its circumferential wall, forming a radial corresponding relationship with the first placement grooves 201. The multi-placement groove design enables the first tool magazine 2 and the second tool magazine 7 to store multiple groups of tools simultaneously, significantly reducing the frequency of downtime for tool change due to insufficient tools, and is suitable for continuous processing of complex processes.
