Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a machining equipment with a multi-tool rapid tool change mechanism. Background Technology

[0002] In the fields of machinery manufacturing, hardware processing, and mold production, CNC machine tools and drilling and milling machining centers are core equipment for achieving precision machining of workpieces. They are widely used in multiple processes such as drilling, milling, boring, tapping, and chamfering of various parts. As the manufacturing industry develops towards automation, large-scale production, and precision, the market demands for processing efficiency, accuracy, and production continuity are constantly increasing. Especially for multi-process machining of complex workpieces in batches, the tool changing mechanisms of traditional machining equipment can no longer meet actual production needs, becoming a key bottleneck restricting processing efficiency and quality.

[0003] Currently, traditional small and medium-sized machining equipment mainly uses manual tool changing. This method has significant limitations: when a workpiece undergoes multi-process machining, the machine needs to be stopped after each process is completed, and the operator must manually remove the current tool head and install a new tool head of the corresponding specification. This not only makes the tool changing process cumbersome and time-consuming, but also results in excessive downtime, seriously affecting continuous processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a processing equipment with a multi-head rapid tool change mechanism, which aims to solve the problems of traditional manual tool changing, which requires frequent machine stops, manual disassembly of the current tool head, and installation of a new tool head of the corresponding specifications, resulting in a cumbersome and time-consuming tool changing process.

[0005] To achieve the above objectives, the present invention provides a processing device with a multi-head rapid tool change mechanism, comprising a base, a drive arm, a coolant gun, a rotary motor, a rotating disk, a drive motor, a tool holder, a cutting tool, and a wastewater discharge assembly; the wastewater discharge assembly is disposed at the bottom of the base, the coolant gun is disposed at the top of the base, the drive arm is fixedly disposed at the top of the base, the rotary motor is fixedly connected to the output end of the drive arm and is located on one side of the drive arm, the rotating disk is fixedly connected to the output end of the rotary motor and is located on the side of the rotary motor away from the drive arm, the drive motor is fixedly connected to the rotating disk and is located around the rotating disk, the tool holder is fixedly connected to the output end of the drive motor and is located on one side of the drive motor, and the cutting tool is disposed on one side of the tool holder.

[0006] The rotating motor includes a mounting base, a motor body, and a reducer. The mounting base is fixedly connected to the output end of the drive arm and is located on one side of the drive arm. The motor body is fixedly connected to the mounting base and is located on one side of the mounting base. The reducer is mounted on the output end of the motor body.

[0007] The rotating disk includes a turntable, a sensing block, and a proximity switch. The turntable is fixedly connected to the output end of the motor body and is located on one side of the motor body. The sensing block is fixedly connected to the turntable and is located on the side of the turntable closer to the motor body. The proximity switch is fixedly connected to the mounting base and is located on the side closer to the turntable.

[0008] The proximity switch includes a connector and a switch body. The connector is fixedly connected to the mounting base and is located on the side of the mounting base closer to the turntable. The switch body is fixedly connected to the connector and is located on the side of the connector away from the mounting base.

[0009] The sewage discharge assembly includes a guide bucket, a filter tank, and a drain pipe. The guide bucket is fixedly connected to the base and located at the bottom of the base. The filter tank is disposed at the bottom of the guide bucket. The drain pipe is connected to the filter tank and located on one side of the filter tank.

[0010] The filter tank includes a tank body, a filter plate, and a fixing rod. The tank body is located at the bottom of the guide bucket, the filter plate is located inside the tank body, and the fixing rod is fixedly connected to the filter plate and hung on the tank body.

[0011] The fixing rod includes a connecting rod, a crossbar, and a hook. The connecting rod is fixedly connected to the filter plate and located on top of the filter plate. The crossbar is fixedly connected to the connecting rod and located between the connecting rods. The hook is fixedly connected to the connecting rod and hung on the tank.

[0012] This invention discloses a machining device with a multi-tool quick-change mechanism. The base (with a protective cover, not shown in the figure) provides a mounting foundation for the drive arm, the coolant gun, and the wastewater discharge assembly. The drive arm drives the rotating disc to rise and fall, moves the tool closer to the workpiece to be machined, and moves the tool along a pre-set path. The drive motor drives the tool holder and the tool mounted on it to rotate at high speed, thereby machining the workpiece. The coolant gun sprays coolant onto the tool to prevent high temperatures from accelerating tool aging. The wastewater discharge assembly discharges machining debris and coolant from the workpiece. To prevent debris and coolant buildup from affecting the cutting tool's machining of the workpiece, when the cutting tool needs to be replaced, the controller controls the rotary motor based on a preset program. The rotary motor rotates and drives the rotary disk to rotate at a certain angle, thereby rotating the required cutting tool to the workstation, thus realizing the cutting tool replacement operation. Compared with the manual cutting tool replacement method, this eliminates the process of disassembling and assembling the cutting tool and does not require machine stoppage. The replacement operation is more convenient and faster, thus solving the problems of traditional manual cutting tool replacement, which requires frequent machine stops, manual disassembly of the current cutting head, and installation of a new cutting head of the corresponding specification. The cutting tool replacement process is cumbersome and time-consuming. Attached Figure Description

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1 to 3 This invention provides a processing device with a multi-head rapid tool change mechanism, including a base 1, a drive arm 2, a coolant gun 3, a rotary motor, a rotating disk, a drive motor 4, a tool holder 5, a cutting tool 6, and a drain assembly; the drain assembly is disposed at the bottom of the base 1, the coolant gun 3 is disposed at the top of the base 1, the drive arm 2 is fixedly disposed at the top of the base 1, the rotary motor is fixedly connected to the output end of the drive arm 2 and is located on one side of the drive arm 2, the rotating disk is fixedly connected to the output end of the rotary motor and is located on the side of the rotary motor away from the drive arm 2, the drive motor 4 is fixedly connected to the rotating disk and is located around the rotating disk, the tool holder 5 is fixedly connected to the output end of the drive motor 4 and is located on one side of the drive motor 4, and the cutting tool 6 is disposed on one side of the tool holder 5.

[0020] In this embodiment, the base 1 provides an installation foundation for the drive arm 2, the coolant gun 3, and the drain assembly. The drive arm 2 is used to drive the rotary table to rise and fall, drive the cutter 6 to approach the workpiece to be processed, and drive the cutter 6 to move according to a pre-set running path. The drive motor 4 is used to drive the tool holder 5 and the cutter 6 mounted on it to rotate at high speed, thereby processing the workpiece. The coolant gun 3 is used to spray coolant onto the cutter 6 to prevent high temperature from accelerating the aging of the cutter 6. The drain assembly is used to discharge the workpiece debris and coolant to prevent the accumulation of debris and coolant. The tool 6 affects the machining of the workpiece. When the tool 6 needs to be replaced for machining, the controller controls the operation of the rotary motor based on a preset program. The rotary motor rotates and drives the rotary disk to rotate at a certain angle, thereby rotating the required tool 6 to the work position, thus realizing the replacement operation of the tool 6. Compared with the manual tool replacement method, it eliminates the disassembly and assembly process of the tool 6 and does not require machine stoppage. The replacement operation is more convenient and faster, thus solving the problem of traditional manual tool replacement, which requires frequent machine stoppage, manual disassembly of the current tool head, and installation of a new tool head of the corresponding specification. The tool replacement process is cumbersome and time-consuming.

[0021] Furthermore, the rotating motor includes a mounting base 7, a motor body 8, and a reducer 9. The mounting base 7 is fixedly connected to the output end of the drive arm 2 and is located on one side of the drive arm 2. The motor body 8 is fixedly connected to the mounting base 7 and is located on one side of the mounting base 7. The reducer 9 is mounted on the output end of the motor body 8.

[0022] In this embodiment, the mounting base 7 provides a stable mounting reference for the motor body 8 and the reducer 9. The motor body 8 is used to provide power to drive the rotating disk to rotate. It cooperates with the controller to receive preset program instructions to achieve precise start-stop and speed adjustment. The reducer 9 is installed at the output end of the motor body 8 to reduce the output speed of the motor body 8 and increase the output torque. This prevents the rotating disk from rotating too fast due to excessive speed of the motor body 8, which would make it impossible to accurately control the rotation angle and ensure that the rotating disk can rotate smoothly and accurately to the preset position.

[0023] Furthermore, the rotating disk includes a turntable 10, a sensing block 11, and a proximity switch. The turntable 10 is fixedly connected to the output end of the motor body 8 and is located on one side of the motor body 8. The sensing block 11 is fixedly connected to the turntable 10 and is located on the side of the turntable 10 closer to the motor body 8. The proximity switch is fixedly connected to the mounting base 7 and is located on the side closer to the turntable 10.

[0024] In this embodiment, the turntable 10 can rotate synchronously under the drive of the rotating motor. The drive motor 4, the tool holder 5, and the tools 6 are evenly installed around its perimeter, realizing a circular arrangement of tools 6 of various specifications, providing a structural basis for rapid tool changing. There are multiple sensing blocks 11, corresponding to the number of tools 6, evenly distributed around the circumference of the turntable 10. They work with the proximity switch to realize rotation counting and precise positioning of the workstation. The proximity switch is fixed on the mounting base 7 and arranged corresponding to the sensing blocks 11. When the rotating motor drives the turntable 10 to rotate, each sensing block 11 will pass through the proximity switch in sequence. The proximity switch generates a pulse signal in real time and transmits it to the controller. The controller accurately identifies the rotation position of the turntable 10 by counting the pulse signals and determines whether the required tool 6 has reached the preset processing position. When the target sensing block 11 is detected to have passed through the proximity switch, the controller immediately controls the rotating motor to brake and stop, ensuring that the tool 6 is accurately aligned, thereby realizing rapid and accurate tool changing and solving the problems of inaccurate positioning and easy tool changing errors in traditional tool changing mechanisms.

[0025] Furthermore, the proximity switch includes a connector 12 and a switch body 13. The connector 12 is fixedly connected to the mounting base 7 and is located on the side of the mounting base 7 closer to the turntable 10. The switch body 13 is fixedly connected to the connector 12 and is located on the side of the connector 12 away from the mounting base 7.

[0026] In this embodiment, one end of the connector 12 is fixedly connected to the mounting base 7, and the other end is used to fix the switch body 13. This is used to precisely fix the switch body 13 near the turntable 10 and aligned with the sensing block 11, ensuring that the switch body 13 can accurately sense and generate a pulse signal when the sensing block 11 rotates past it, avoiding signal loss or false triggering due to installation misalignment. The switch body 13 is used to detect the position of the sensing block 11 in real time. When the sensing block 11 rotates to the position corresponding to the switch body 13, the switch body 13 generates a pulse signal and transmits it to the controller, providing the controller with signal support for rotation counting and station positioning. This, together with the sensing block 11, enables the turntable 10 to achieve precise indexing, ensuring the accuracy of the tool 6's rapid tool change and avoiding problems such as tool change misalignment or the tool 6's inability to be aligned.

[0027] Furthermore, the sewage discharge assembly includes a guide bucket 14, a filter tank, and a drain pipe 15. The guide bucket 14 is fixedly connected to the base 1 and is located at the bottom of the base 1. The filter tank is disposed at the bottom of the guide bucket 14. The drain pipe 15 is connected to the filter tank and is located on one side of the filter tank.

[0028] In this embodiment, the guide bucket 14 is fixed at the bottom of the base 1, directly below the processing area, and is used to quickly guide the processing debris and coolant into the filter tank. The filter tank filters and separates the waste coolant mixed with debris, intercepts the processing debris, and prevents the debris from clogging the drain pipe 15. The drain pipe 15 is connected to the filter tank and is used to discharge the filtered waste coolant from the equipment, so as to achieve orderly sewage discharge.

[0029] Furthermore, the filter tank includes a tank body 16, a filter plate 17, and a fixing rod. The tank body 16 is disposed at the bottom of the guide bucket 14, the filter plate 17 is disposed inside the tank body 16, and the fixing rod is fixedly connected to the filter plate 17 and hung on the tank body 16.

[0030] In this embodiment, the tank 16 is used to receive debris and waste coolant from the guide bucket 14, providing a stable installation space for the filter plate 17. The filter plate 17 is horizontally positioned near the top of the tank 16 to intercept processing debris, allowing waste coolant to flow down through the pores of the filter plate 17, thus separating the debris from the coolant and preventing debris from flowing into the drain pipe 15 and causing blockage. It also facilitates subsequent centralized cleaning of debris. The fixing rod is fixedly connected to the filter plate 17 to suspend and fix the filter plate 17 at the top edge of the tank 16. Operators can quickly remove the filter plate 17 through the fixing rod, clean the intercepted debris, and then resuspend it, ensuring that the filter plate 17 always remains unobstructed and guaranteeing filtration and sewage discharge efficiency.

[0031] Furthermore, the fixing rod includes a connecting rod 18, a crossbar 19, and a hook 20. The connecting rod 18 is fixedly connected to the filter plate 17 and is located on top of the filter plate 17. The crossbar 19 is fixedly connected to the connecting rod 18 and is located between the connecting rods 18. The hook 20 is fixedly connected to the connecting rod 18 and is hung on the trough 16.

[0032] In this embodiment, the connecting rods 18 are symmetrically arranged on both sides of the top of the filter plate 17 for a stable connection between the filter plate 17 and the hook 20, ensuring that the filter plate 17 will not tilt or fall off after being suspended. The crossbar 19 is horizontally fixed between the two connecting rods 18 to enhance the overall structural strength of the fixing rod, prevent the connecting rod 18 from deforming due to force, and provide a gripping part for the operator to easily remove and install the filter plate 17. The hook 20 is fixedly connected to the connecting rod 18, and its shape is adapted to the top edge of the tank 16. It is used to suspend the entire filter plate 17 on the top of the tank 16 through the fixing rod, realizing quick installation and removal of the filter plate 17. This ensures the stability of the filter plate 17 after installation and facilitates regular cleaning of debris, reducing maintenance difficulty.
