Description

Technical Field

[0001] This utility model relates to the field of deburring machine technology, and in particular to a multi-station deburring machine. Background Technology

[0002] Deburring machines remove burrs from workpiece surfaces using mechanical, chemical, vibration, or thermal methods. Mechanical deburring machines utilize friction or cutting forces to remove burrs, requiring appropriate tools for different burr structures, such as brushes, grinding wheels, and various deburring tools. Most existing mechanical deburring machines are single-station machines, such as the single-station six-axis deburring machine disclosed in Chinese Utility Model Patent Application No. 202421155496.5. Single-station deburring machines can only deburr one workpiece at a time, resulting in low efficiency. When deburring large quantities of workpieces, companies need to equip multiple deburring machines simultaneously, occupying significant factory space. Conversely, when order volumes are small, some deburring machines remain idle in the factory, increasing production costs and reducing company profits. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a multi-station deburring machine, which solves the problem of low production efficiency of existing single-station deburring machines.

[0004] This utility model provides a multi-station deburring machine, including a base, a support, and multiple deburring devices.

The swing-type worktable is movably mounted on the base via an X-axis drive module and a Y-axis drive module. The turrets of the multiple deburring devices are mounted on the same lifting seat and located directly above the corresponding clamp. The lifting seat and the swing-type worktable are both arranged along the X-axis direction. The lifting seat is movably mounted on one side of the support via a Z-axis drive module. A counterweight device is provided on the support and connected to the lifting seat. The rotation axis of each turret is arranged along the X-axis direction, and each turret is equipped with multiple deburring tools. The multiple tools perform various deburring operations on the workpieces held by the corresponding clamps.

[0005] In some embodiments, the counterweight device includes a counterweight block, a pull belt, and rollers. The counterweight block is disposed in a counterweight movable cavity inside the support. The counterweight block is connected to the lifting seat via the pull belt. The rollers are disposed at the top of the support via a mounting bracket. The two ends of the pull belt are fixed to the counterweight block and the lifting seat respectively via connectors. The middle part of the pull belt rests on the rollers.

[0006] In some embodiments, a guide rod is provided between the counterweight movable cavity and the mounting frame. The guide rod is arranged along the Z-axis and is located between two tension straps. The counterweight block has a through-hole, and the guide rod passes through the through-hole and is slidably connected to a linear bearing in the through-hole.

[0007] In some embodiments, the mounting bracket has a mounting groove along the Y-axis, and two rollers are provided in the mounting groove. The shaft of the rollers is connected to the inner walls of both sides of the mounting groove. The mounting groove communicates with the counterweight movable cavity through a connecting hole. The pull strap passes through the counterweight movable cavity, the connecting hole, and the mounting groove in sequence, and is connected to the two rollers in the mounting groove in sequence.

[0008] In some embodiments, the support has two sets of tracks symmetrically arranged on both sides of the Z-axis drive module, each set of tracks including two parallel Z-axis guide rails, and the back of the lifting seat is slidably connected to the four Z-axis guide rails.

[0009] In some embodiments, multiple mounting seats are vertically arranged on the front side of the lifting seat, and the turrets of the multiple deburring devices are each mounted on the corresponding mounting seats. The turret includes a rotating tool holder, a first hollow shaft, and a rotary motor. Multiple tools are arranged at equal angles on the rotating tool holder, and the tools are installed radially. The rotating tool holder is mounted on one side of the mounting plate through the first hollow shaft, which is arranged along the X-axis. The rotary motor drives the rotating tool holder to rotate around the rotation axis in the X-axis direction through the first hollow shaft. The rotary motor is arranged vertically on the side of the first hollow shaft near the lifting seat.

[0010] In some embodiments, the swing table includes a rocker arm, a support, and a first drive motor. The rocker arm is connected to the support via a second hollow shaft. Multiple clamps are arranged side by side on the rocker arm. The support is mounted on an X-axis drive module, which is connected to a base via a Y-axis drive module. The first drive motor is mounted on one end of the support and is connected to the rocker arm via a transmission connection.

[0011] In some embodiments, the fixture includes a rotary table and a second drive motor. The rotary table is located on one side of the rocker arm near the turret, and the second drive motor is located on the other side, driving the rotary table to rotate.

[0023] The specific embodiments of this utility model are described with reference to the accompanying drawings.

[0024] refer to Figure 1The figure shows a three-dimensional structural diagram of a multi-station deburring machine. The deburring machine mainly consists of a base 3, a support 1, and four deburring devices 100. The four deburring devices 100 are arranged side by side between the base 3 and the support 1 to form four deburring stations. It can deburr four workpieces at the same time. The turret 2 on each station can be equipped with six deburring tools, which can perform six kinds of deburring operations on the workpiece without stopping the machine to change the deburring tools.

[0025] refer to Figures 1 to 2 A multi-station deburring machine includes a base 3, a support 1, and four deburring devices 100. The support 1 is fixed above the base 3, and the four deburring devices 100 are arranged side by side between the base 3 and the support 1. Each deburring device 100 includes a clamp 5 and a turret 2. The clamps 5 of the four deburring devices 100 are arranged side by side on the same swing-type worktable 4. The swing-type worktable 4 is movably mounted on the base 3 via an X-axis drive module 34 and a Y-axis drive module 31. The turrets of the four deburring devices 100... The turret 2 is set on the same lifting seat 11 and located directly above the corresponding fixture 5. The lifting seat 11 and the swing worktable 4 are both set along the X-axis. The lifting seat 11 is movably set on one side of the support 1 through the Z-axis drive module 15. The support 1 is equipped with a counterweight device 6, which is connected to the lifting seat 11. The rotation axis of each turret 2 is set along the X-axis. Each turret 2 is equipped with multiple deburring tools. Multiple tools are used to perform various deburring operations on the workpieces held by the corresponding fixture 5.

[0026] The multi-station deburring machine of this application, through four deburring devices 100 arranged side by side, can simultaneously deburr four workpieces, improving production efficiency and reducing production costs for enterprises. Arranging the turrets 2 of the four deburring devices 100 side by side along the X-axis reduces the width of the deburring machine in the X-axis direction, making the overall structure compact, reducing the size of the deburring machine, and improving the space utilization of the factory. The counterweight device 6 balances the weight of the lifting seat 11 and the four turrets 2, enabling the Z-axis drive module 15 to stably drive the four turrets 2 to rise and fall, preventing vibration of the spindle 24 and tools of the turrets 2, improving the control accuracy of the tools in the Z-axis direction. The counterweight device 6 also reduces the load on the Z-axis drive module 15, extending its service life.

[0027] It should be further noted that the X-axis drive module 34, Y-axis drive module 31, and Z-axis drive module 15 all include a motor and a lead screw assembly (only the lead screw assembly is shown in the attached diagram; the motor is not shown). Each module uses a motor as its power source. The Z-axis drive module 15 is installed between the support 1 and the lifting seat 11, the Y-axis drive module 31 is installed between the base 3 and the movable seat 33, and the X-axis drive module 34 is installed between the movable seat 33 and the swing table 4. The Z-axis drive module 15 drives the lifting seat 11 and the tool. The tool moves up and down along the Z-axis guide rail 16, the Y-axis drive module 31 drives the movable seat 33 to move along the Y-axis guide rail 32, so as to move the workpiece back and forth in the Y-axis direction, and the X-axis drive module 34 drives the swing table 4 to move along the X-axis guide rail 35, so as to move the workpiece left and right in the X-axis direction. At the same time, the tool driven by the spindle 24 rotates around the axis, the workpiece rotates around the axis on the fixture 5, and the swing table 4 drives the fixture 5 and the workpiece to rotate around the X-axis, realizing multi-axis linkage, which can effectively perform deburring operations on the workpiece.

[0028] To balance the weight of the lifting platform 11 and the four turrets 2, in this embodiment, reference is made to... Figure 1 and Figure 2 The counterweight device 6 includes a counterweight block 61, a pull belt 64, and a roller 66. The counterweight block 61 is installed in the counterweight movable cavity 13 inside the support 1. The counterweight block 61 is connected to the lifting seat 11 through the pull belt 64. The roller 66 is installed at the top of the support 1 through the mounting bracket 7. The two ends of the pull belt 64 are fixed to the counterweight block 61 and the lifting seat 11 respectively through the connector 65. The middle part of the pull belt 64 rests on the roller 66.

[0029] Understandably, the four turrets 2 are mounted on a lifting platform 11. The combined weight of the lifting platform 11 and the four turrets 2 is significant. Without the counterweight 6, it would place a heavy load on the Z-axis drive module 15, resulting in high energy consumption and hindering the Z-axis drive module 15's stroke control over the lifting platform 11. The counterweight 61 weighs more than 90% of the combined weight of the lifting platform 11 and the four turrets 2, thus better balancing their weight. The pull belt 64 is arranged in an inverted U-shape on the support 1, and the rollers 66 reduce the friction on the pull belt 64, ensuring that the counterweight 61 can smoothly pull the lifting platform 11.

[0030] To ensure that the counterweight 61 can move stably up and down, in this embodiment, reference is made to... Figure 2 A guide rod 63 is provided between the counterweight movable cavity 13 and the mounting frame 7. The guide rod 63 is set along the Z-axis and is located between the two pull straps 64. The counterweight block 61 is provided with a guide hole, and the guide rod 63 passes through the guide hole and is slidably connected with the linear bearing 62 in the guide hole.

[0031] It is understandable that the guide rod 63 set along the Z-axis is slidably connected to the linear bearing 62 in the guide hole of the counterweight 61. The counterweight 61 moves up and down along the guide rod 63, thereby ensuring that the counterweight 61 can move stably in the counterweight movable cavity 13. The guide rod 63 is located between the two pull straps 64, so that the guide rod 63 is located at the geometric center of the counterweight 61, so that the counterweight 61 will not shake during the up and down movement, thereby avoiding the counterweight 61 from hitting the support 1 and ensuring the safe use of the deburring machine.

[0032] To ensure stable movement of the pull belt 64, in this embodiment, reference is made to... Figure 1 and Figure 2 The mounting frame 7 has a mounting groove 71 along the Y-axis. Two rollers 66 are installed in the mounting groove 71. The shaft of the rollers 66 is connected to the inner walls of both sides of the mounting groove 71. The mounting groove 71 is connected to the counterweight movable cavity 13 through the connecting hole 72. The pull strap 64 is sequentially inserted between the counterweight movable cavity 13, the connecting hole 72, and the mounting groove 71, and is sequentially connected to the two rollers 66 in the mounting groove 71.

[0033] It should be further explained that the mounting frame 7 is fixed to the top of the support 1 by the pad 73. The mounting frame 7 is H-shaped, with two mounting slots 71 on the two vertical parts for mounting four rollers 66 and two pull straps 64. The horizontal part is fixed to the guide rod 63. The guide rod 63 runs through the counterweight movable cavity 13 from top to bottom. The two ends of the guide rod 63 are fixed to the mounting frame 7 and the support 1 respectively, so that the running structure between the guide rod 63, the pull strap 64 and the counterweight block 61 can remain stable.

[0034] Understandably, the four rollers 66 are set in the two mounting slots 71 of the mounting frame 7. The pull strap 64 forms an inverted U-shape with the two rollers 66 on one side of the lifting seat 11 and the other side of the counterweight movable cavity 13, so that the counterweight block 61 and the lifting seat 11 are stably connected by the two pull straps 64, forming a counterweight balance structure similar to the seesaw principle. The pull strap 64 is relatively wide, which increases the contact area between the pull strap 64 and the rollers 66, reduces the possibility of the pull strap 64 detaching from the rollers 66, and ensures that the pull strap 64 can run smoothly. Then, through the limiting of the connecting hole 72, it is ensured that the pull strap 64 can act stably between the counterweight block 61 and the lifting seat 11.

[0035] In order to ensure that the lifting platform 11 and the four turrets 2 can move stably up and down, in this embodiment, reference is made to Figure 1 The support 1 has two sets of tracks symmetrically arranged on both sides of the Z-axis drive module 15. Each set of tracks includes two parallel Z-axis guide rails 16. The back of the lifting seat 11 is slidably connected to the four Z-axis guide rails 16.

[0036] It is understandable that the lifting seat 11 and the four turrets 2 are relatively heavy and have a large overall inertia. The traditional two guide rails are not enough to stabilize the lifting seat 11. In this embodiment, four Z-axis guide rails 16 are arranged in pairs on both sides of the Z-axis drive module 15. The four Z-axis guide rails 16 stably guide the lifting seat 11 to move up and down, ensuring that the four turrets 2 and the tools can move stably in the Z-axis direction.

[0037] In order for Dota 2 to achieve automatic tool changing, in this embodiment, refer to Figure 1 and Figure 2 A fixing groove 14 is provided on the front side of the lifting seat 11, and four mounting seats 12 are vertically arranged in the fixing groove 14. The width of the fixing groove 14 matches the length of the mounting seat 12, so that the upper and lower sides of the mounting seat 12 abut against the upper and lower inner walls of the fixing groove 14, ensuring that the mounting seat 12 can be stably connected to the lifting seat 11. The turrets 2 of the four deburring devices 100 are each mounted on the corresponding mounting seats 12. The turret 2 includes a rotating tool holder 21, a first hollow shaft 22, and a rotating motor 23. The rotating tool holder 21 is provided with multiple tools at equal angles and the tools are installed radially. The rotating tool holder 21 is mounted on one side of the mounting plate through the first hollow shaft 22. The first hollow shaft 22 is arranged along the X-axis direction. The rotating motor 23 drives the rotating tool holder 21 to rotate around the rotation axis in the X-axis direction through the first hollow shaft 22. The rotating motor 23 is arranged vertically on the side of the first hollow shaft 22 near the lifting seat 11.

[0038] It should be further explained that the rotary tool holder 21 has six positions, which can be used to install six kinds of deburring tools, including cutting tools. Commonly used deburring tools include deburring milling cutters, deburring tips, steel brushes, wire brushes, deburring files, and grinding heads. The deburring tools are mounted on the rotary tool holder 21 via the spindle 24. The spindle 24 can drive the deburring tools to rotate or not. The fixture 5 can also drive the workpiece to rotate or not. The appropriate method can be flexibly selected for deburring operations.

[0039] It is understandable that the lifting seat 11 is set along the X-axis, and the mounting seat 12 is set perpendicular to the lifting seat 11, so that the rotation axis of the turret 2 can be set along the X-axis. The rotary motor 23 is tangent to the first hollow shaft 22. The rotary motor 23 is set vertically upward and will not occupy the space in the X-axis direction, so that the width of the turret 2 in the X-axis direction is minimized, thereby ensuring that the space occupied by the four turrets 2 in the X-axis direction is small. Furthermore, by reducing the thickness of the mounting seat 12 at the position where the first hollow shaft 22 is installed, the structure of the whole machine is more compact and the size is smaller. The rotary motor 23 drives the rotary tool holder 21 to rotate through the first hollow shaft 22 to realize automatic tool changing, which is convenient for switching the corresponding tool according to the deburring requirements of different workpieces, and can adjust the angle of the tool to perform deburring operations on the workpiece at different angles.

[0040] In order to control the movement of the workpiece in the X and Y axis directions, in this embodiment, reference is made to... Figure 1 The swing-type worktable 4 includes a rocker arm 42, a bracket 41, and a first drive motor 43. The rocker arm 42 is connected to the bracket 41 through a second hollow shaft 44. Multiple clamps 5 are arranged side by side on the rocker arm 42. The bracket 41 is mounted on an X-axis drive module 34. The X-axis drive module 34 is connected to the base 3 through a Y-axis drive module 31. The first drive motor 43 is mounted on one end of the bracket 41. The first drive motor 43 is connected to the rocker arm 42 in a transmission connection.

[0041] Understandably, the swing worktable 4, X-axis drive module 34, and Y-axis drive module 31 are stacked sequentially on top of the base 3, which is fixed to the factory floor. The X-axis drive module 34 and Y-axis drive module 31 control the swing worktable 4 to move in the X-axis and Y-axis directions respectively, precisely moving the workpiece on the swing worktable 4 to below the turret 2. The first drive motor 43 controls the rocker arm 42 to swing, so that the workpiece swings relative to the turret 2 at a corresponding angle. In conjunction with the tool on the turret 2, the deburring requirements of the workpiece at different angles and positions are met, thus improving the deburring quality.

[0042] In order to drive the deburring tool to rotate, in this embodiment, reference is made to... Figure 1 The fixture 5 includes a rotary table 51 and a second drive motor 52. The rotary table 51 is located on the side of the rocker arm 42 near the turret 2, and the second drive motor 52 is located on the other side. The second drive motor 52 drives the rotary table 51 to rotate.

[0043] Understandably, the workpiece is placed on the rotary table 51 and locked onto the rotary table 51 by a structure corresponding to the workpiece. The second drive motor 52 can drive the rotary table 51 to rotate according to the needs of the deburring operation, adjust the posture of the workpiece, and enable the tool to perform deburring operation on the workpiece at different angles and positions, thus ensuring the quality of deburring.

[0044] In the working process of this embodiment, four workpieces to be deburred are first placed on the rotary tables 51 of four clamps 5 and locked. The X-axis drive module 34 and the Y-axis drive module 31 drive the swing table 4 to move below the turret 2. The first drive motor 43 drives the rocker arm 42 to swing, and the second drive motor 52 drives the rotary table 51 to rotate, aligning the position of the workpiece to be deburred with the turret 2. At the same time, the turret 2 switches the corresponding tool to face the workpiece according to the type of burr. The Z-axis drive module 15 drives the lifting seat 11 to descend, so that the tool on the turret 2 approaches the workpiece to perform deburring. During the deburring process, the weight of the lifting seat 11 and the four turrets 2 is balanced by the counterweight device 6, so that the tool can stably advance and retract. After the burr of the workpiece is removed, the swing table 4 returns to the initial position, the workpiece is taken out, and a new workpiece is replaced for the next round of deburring.

[0045] 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.
