Description

Technical Field

[0001] The utility model relates to the technical field of friction plate processing in the machinery industry, in particular to an angle-adjustable linear grooving device. Background Art

[0002] Friction plates and clutch plates are common mechanical components. To enhance the braking effect of friction plates and the disengagement or engagement of clutch plates, oil grooves need to be machined into their surfaces. The purpose of the oil grooves is to improve lubrication. They store lubricating oil, helping to reduce direct metal-to-metal contact and thus reduce wear. This is particularly important for clutch plates, as they are often in a semi-engaged state, prone to sliding friction. Furthermore, through the oil grooves, the lubricating oil can remove some heat during operation, helping to cool the friction surfaces and prevent performance degradation or damage caused by overheating. Furthermore, to enhance engagement and disengagement, a reasonable oil groove layout for the clutch can help achieve a smoother engagement and disengagement process, reduce the sense of impact, and improve driving comfort and system responsiveness. Existing oil groove processing is generally modified by a bench drilling machine, an electromagnetic magnetic chuck, etc. The slot milling cutter is driven by a motor to rotate automatically, but the up and down movement of the milling cutter and the propulsion of the electromagnetic chuck still need to rely on manual operation, which greatly affects the slotting of the friction plate or clutch plate. Workers need to repeatedly load and unload materials, and measure and adjust the slotting angle of the friction plate or clutch plate at the same time, resulting in low processing efficiency, low oil groove processing accuracy, and the inability to adjust the slotting angle of the friction plate or clutch plate. Utility Model Content

[0003] Technical problems to be solved by utility models

[0004] In response to the technical problems of low efficiency, low processing accuracy and inability to adjust the angle of existing friction plates or clutch plates, the utility model provides an adjustable angle linear grooving device, which can automatically adjust the grooving angle on the tooling, and is more accurate than traditional methods, and also improves processing efficiency.

[0005] Technical Solution

[0006] In order to solve the above problems, the technical solution provided by the present invention is as follows:

[0007] A linear slotting device with adjustable angle comprises a suction cup; a workbench comprising a matching worm wheel and a worm, wherein the worm rotates circumferentially to drive the worm wheel to rotate, the worm wheel is coaxially fixed to the suction cup, the worm is provided with a thread and is coaxially connected to an adjustment servo motor, and the workbench is slidably arranged through a screw structure; a slotting blade assembly is arranged above the suction cup, comprising an annular blade and a cutter shaft, the cutter shaft is connected to a spindle motor, the annular blade is perpendicular to the axial direction of the cutter shaft, and a plurality of sleeved clamping blocks are provided on the cutter shaft, and the annular blade is placed in the middle of the clamping blocks and clamped and fixed.

[0008] The suction cup is used to fix the workpiece to be processed, ensuring that it remains stable and motionless during the processing, thereby improving the processing accuracy.

[0009] Workbench and adjustment mechanism:

[0010] Worm Gear Drive: The rotation of the worm drives the worm wheel, which in turn rotates the suction cup, thereby adjusting the slotting angle. This transmission method offers a high reduction ratio and is suitable for fine adjustments. By adjusting the servo motor to provide the power source and controlling the motor's speed and direction, the suction cup's rotational position can be precisely adjusted, enabling fine-tuning of the slotting angle. The lead screw structure allows the worktable to move smoothly along a linear path, ensuring positional accuracy during the slotting process.

[0011] Grooving blade assembly:

[0012] The annular blade is specifically designed to cut linear oil grooves in workpiece surfaces. The blade spindle is connected to the spindle motor, which drives the blade to perform the cutting operation. A clamping block secures the blade, preventing it from shifting during high-speed rotation and facilitating the replacement of blades of varying specifications to suit different machining needs.

[0013] Optionally, the tooth profile of the worm wheel and the tooth profile of the thread of the worm are both trapezoidal teeth.

[0014] The trapezoidal tooth profile has a larger contact area and can withstand larger loads, performing particularly well in environments with heavy loads or requiring long periods of continuous work. Smooth transmission: The meshing of the trapezoidal tooth profile is smoother, which can reduce vibration and noise and improve the stability of the transmission system, which is especially important for precision machining. Good self-locking performance: Due to the special shape of the trapezoidal teeth, the meshing between the worm and the worm wheel has a certain self-locking characteristic, that is, when the worm stops rotating, it is difficult for the worm wheel to rotate in the opposite direction, which helps to maintain the accuracy and stability of the processing position. Good wear resistance: The trapezoidal tooth profile has a longer contact line and less pressure per unit area, so it wears more slowly, extending the service life of the transmission mechanism.

[0015] Optionally, the suction cup is a vacuum suction cup or an electromagnetic suction cup.

[0016] Vacuum chucks can absorb workpieces of various materials, including metal, plastic, glass, etc. For ferromagnetic materials, electromagnetic chucks can provide very strong adsorption force.

[0017] Optionally, the slotting blade assembly further comprises a bearing seat rotatably connected to the cutter shaft, the cutter shaft is extendedly connected to a pulley, and the pulley is connected to the spindle motor via a belt.

[0018] The bearing housing is mounted on the cutter shaft, providing stable support and ensuring concentricity and stability during high-speed rotation. The balls or rollers within the bearing significantly reduce friction between the cutter shaft and the bearing housing, lowering energy consumption and extending service life. High-quality bearings ensure accurate rotation of the cutter shaft, reduce vibration and vibration, and improve machining quality. The bearings offer excellent wear and fatigue resistance, enabling them to operate under high loads for extended periods. Bearing housings are typically designed for easy disassembly and replacement, facilitating regular maintenance and bearing replacement.

[0019] The pulley transmits power from the spindle motor to the cutter shaft via a belt, causing the cutter shaft to rotate. By varying the pulley diameter, different transmission ratios can be achieved, thereby adjusting the cutter shaft's speed. Belt drives offer a certain degree of flexibility, absorbing some vibration and shock, minimizing damage to the equipment. When the load exceeds the belt's carrying capacity, the belt slips, providing overload protection and preventing damage to the motor and cutter shaft. Compared to gear drives, belt drives are quieter, resulting in a quieter working environment. The belt drive system's simple structure makes maintenance and belt replacement relatively easy.

[0020] Optionally, the diameter of the annular blade is larger than the diameter of the clamping block.

[0021] The larger insert diameter can provide sufficient cutting space and is suitable for processing oil grooves of different widths and depths.

[0022] Optionally, the screw structure of the workbench is connected to an X-axis servo motor.

[0023] The servo motor's closed-loop control system monitors and adjusts the worktable's position in real time, ensuring that each movement achieves the desired precision. The servo motor's rapid response enables the worktable to quickly reach the desired position, improving processing efficiency. The servo motor's high precision and stability ensure repeatability of each process, improving consistent product quality. The servo motor can be controlled through programming to achieve complex motion trajectories and multi-step processing procedures, adapting to a variety of processing needs.

[0024] Optionally, the slotting blade assembly is connected to a tool holder body, and the tool holder body is liftably arranged through a screw rod structure and is transmission-connected to a Z-axis servo motor.

[0025] The Z-axis servo motor drives the tool holder to move along the Z-axis direction (vertical direction) through the screw structure to achieve precise control of the blade position.

[0026] Optionally, the adjustment servo motor, the X-axis servo motor and the Z-axis servo motor are all connected to a controller.

[0027] The controller can simultaneously control and adjust the servo motors, including the X-axis servo motor and the Z-axis servo motor, achieving multi-axis linkage. Based on the preset machining program, the controller can plan complex motion trajectories to ensure coordinated movement of each axis. The controller monitors the position, speed, and torque of each axis in real time to ensure machining stability and accuracy. The controller also features fault diagnosis capabilities, providing timely alarms and implementing appropriate protective measures when an anomaly occurs.

[0029] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0030] The technical solution provided by the utility model includes a suction cup; a workbench including a matching worm wheel and a worm, the worm driving the worm wheel to rotate circumferentially, the worm wheel being coaxially fixed to the suction cup, the worm being provided with a thread and coaxially connected to an adjustment servo motor, the workbench being slidably arranged via a screw structure; a slotting blade assembly being arranged above the suction cup, including an annular blade and a cutter shaft, the cutter shaft being connected to a spindle motor, the annular blade being perpendicular to the axial direction of the cutter shaft, the cutter shaft being provided with a plurality of sleeved clamping blocks, the annular blade being clamped and fixed in the middle of the clamping blocks, and the use of a servo motor and a precision transmission mechanism enabling very fine angle adjustment to be achieved, ensuring that the desired effect is achieved each time the processing is performed.

[0036] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0037] Example

[0038] Combined with attachment Figure 1-4 A linear slotting device with adjustable angle includes a bed 1 and a column 11, the column 11 is vertically fixed to the bed 1, a workbench 6 and a suction cup 7 are arranged on the bed 1, and a slotting blade assembly 8 is arranged on the column 11.

[0039] The suction cup 7 is either a vacuum cup or an electromagnetic cup. The cup is circular and features multiple suction holes on its top surface. These holes are distributed across the entire surface of the cup, ensuring uniform force across the contact surface between the workpiece and the cup, thereby enhancing the stability and reliability of the fixation. Each suction hole is connected to one or more vacuum tubes via internal channels. The vacuum tubes are key components connecting the cup 7 to the vacuum pump, responsible for extracting air from the cup to create a vacuum. The vacuum pump is crucial for generating the vacuum. When the vacuum pump is activated, it extracts air from the cup through the vacuum tubes, creating a subatmospheric pressure environment within the cup. This creates a secure fixation by applying atmospheric pressure to the workpiece against the cup, effectively securing it. The electromagnetic cup 7 houses one or more electromagnetic coils. These coils are typically made of insulated copper wire wound around an iron or magnetic core. When current flows through the coils, a magnetic field is generated, causing the electromagnetic cup to generate suction. The coils are connected to a battery pack via wires. The battery pack can be a rechargeable lithium battery or other type of battery that provides the necessary current to activate the coil. The design of the battery pack should take into account capacity, charging time and safety to ensure long-term stable operation.

The workbench 6 is slidably arranged through a screw structure. The worm wheel is fixed to the bottom of the workbench 6 and is driven to rotate by the worm 604 as a passive component. After the worm wheel 602 rotates, it can drive the suction cup 7 to rotate, thereby rotating the workpiece and adjusting the angle of the slot. The tooth profile of the worm wheel 602 and the tooth profile of the rod thread 605 of the worm 604 are both trapezoidal teeth. The end of the worm 604 is rotatably connected to the bearing seat 606. The bearing seat 606 is mounted on the stand 601 of the workbench 6, and the other end is connected to the adjustment servo motor 607.

[0042] Combined with attachment Figure 4 The slotting blade assembly 8 is disposed above the suction cup 7 and includes an annular blade 801 and a blade shaft 802. The blade shaft 802 is connected to the spindle motor 9. The annular blade 801 is perpendicular to the axis of the blade shaft 802. The blade shaft 802 is provided with a plurality of sleeved clamping blocks. The annular blade 801 is clamped and fixed between the clamping blocks. The diameter of the annular blade 801 is larger than the diameter of the clamping blocks.

[0043] The slotting blade assembly 8 also includes a bearing seat rotatably connected to the cutter shaft 802, and the cutter shaft 802 is extended to be connected to a pulley 805, which is connected to the spindle motor 9 via a belt. The bearing seats at both ends are divided into a second bearing seat 803 and a third bearing seat 804, and the pulley 805 is located outside the second bearing seat 803.

[0044] The slotting blade assembly 8 is connected to the tool holder body 10, which is arranged to be raised and lowered via a screw mechanism and is transmission-connected to a Z-axis servo motor 12. The tool holder body 10 is slidably connected to the column 11 via a Z-axis linear guide 14, which is fixed to the side of the column 11. The column 11 is a rectangular frame with a crossbeam at the top, on which the Z-axis servo motor 12 is mounted. The output end of the Z-axis servo motor 12 is connected to a Z-axis screw 13, which is threadedly connected to the tool holder body 10 via 605 threads. The tool holder body 10 is provided with a threaded hole. The spindle motor 9 is fixed to the tool holder body 10.

[0045] The regulating servo motor 607 , the X-axis servo motor 4 and the Z-axis servo motor 12 are all connected to a controller.

[0046] Working principle:

[0047] The workpiece is placed on electromagnetic chuck 7, which is magnetized and holds the workpiece against worktable 6. The tool is then adjusted to zero on the Z-axis. The program is then started. The Z-axis servo motor 12 moves the tool shaft 802 to the appropriate position. The tool shaft 802 is rotated by the spindle motor 9. The X-axis servo motor 4 moves the worktable 6, passing under the tool shaft 802. The worm gear in worktable 6, driven by worm 604, rotates precisely, allowing the slot to be cut at any angle. This angle is precisely controlled by the servo motor 607.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
