Description

Technical Field

[0001] The utility model relates to the technical field of precision grinding processing, in particular to a replaceable vertical thinning machine. Background Art

[0002] Metal circular saw blades are discs with a large diameter-to-thickness ratio. During processing, both end faces must be ground, and the precision level required is high. Currently, the equipment commonly used in the grinding of circular saw blades is a circular table surface grinder, which sucks the saw blade (workpiece) tightly onto an electromagnetic chuck. The electromagnetic chuck can drive the saw blade to rotate together, and the grinding head uses the end face or circumference of a large-diameter disc grinding wheel for grinding. As the grinding head moves up and down and left and right, it can grind the end face of the saw blade. However, the existing grinding process has requirements for the workpiece when using an electromagnetic chuck. The workpiece must be magnetizable. The electromagnetic chuck cannot be used for workpieces of other materials. The general circular table surface grinder is an integrated structure. If you want to process workpieces of other materials, you can only replace the grinding equipment, which not only increases the cost of the processing equipment, but also reduces the overall processing efficiency. Utility Model Content

[0003] Technical problems to be solved by utility models

[0004] In response to the technical problem that the existing electromagnetic chuck for grinding processing cannot accommodate workpieces of all materials, thereby increasing the cost of processing equipment, the utility model provides a replaceable vertical thinning machine, which can flexibly replace the electromagnetic chuck and the vacuum chuck, and can fix workpieces of all materials, thereby improving the overall processing efficiency and, most importantly, reducing the cost of processing equipment.

[0005] Technical Solution

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

[0007] A replaceable vertical thinning machine includes a grinding wheel, which is connected to a column for lifting; a workbench, which includes a rotating motor, a rotating shaft, a drag plate and a turntable, wherein the rotating shaft is transmission-connected to the rotating motor, the rotating shaft passes through the drag plate, and the turntable is rotatably connected to the drag plate, the top of the rotating shaft is fixed to the turntable, the bottom of the drag plate is connected to a guide rail and a screw rod, and the top of the turntable is detachably connected to a vacuum suction cup or an electric suction cup, and the vacuum suction cup or the electric suction cup cooperates with the position of the grinding wheel.

[0008] The grinding wheel is a key component in grinding or thinning operations, while the lifting system (connected to the column) allows the wheel's position to be adjusted according to the workpiece's height, ensuring precision and efficiency during machining. The worktable assembly: The rotary motor and rotating shaft provide rotational power to the workpiece, ensuring even contact with the grinding wheel. The carriage supports the entire rotation system and uses guide rails and leadscrews to achieve fine-tuning in the horizontal direction, ensuring accurate relative positioning between the workpiece and the grinding wheel. The turntable directly contacts the workpiece, securing it and rotating with the rotating shaft. Interchangeable suction cups: With optional vacuum and electric suction cups, the machine can choose the most appropriate holding method based on the workpiece's material (e.g., metal, non-metal, etc.), greatly expanding its application range. Electric suction cups can be used for metal workpieces, while vacuum suction cups are more suitable for non-metallic materials. Metal workpieces are generally heavier than non-metallic materials, and vacuum suction cups may lack sufficient grip for these heavy workpieces. This makes replacing them with electric suction cups a convenient solution, significantly improving grip. Vacuum cups provide sufficient suction force for lightweight plastic parts or other workpieces. Furthermore, vacuum and electric cups offer the advantage of higher retention efficiency compared to traditional clamping methods, contributing to improved overall processing efficiency. By enabling quick interchange of different cup types to accommodate a wide range of workpiece materials, this vertical thinning machine not only increases processing flexibility and efficiency, but also reduces the high costs associated with purchasing multiple specialized pieces of equipment.

[0009] Optionally, the turntable and the vacuum suction cup or electric suction cup are detachably connected via bolts.

[0010] The use of bolt connections means that the suction cups can be replaced in a short time without the need for complicated tools or procedures, thus reducing preparation time and improving work efficiency.

[0011] Optionally, a suction hole is provided on the top surface of the vacuum suction cup, the suction hole is connected to a vacuum tube, and the vacuum tube is connected to a vacuum pump.

[0012] The top surface of the vacuum cup is equipped with multiple suction holes, distributed across the entire surface. These holes ensure uniform force across the contact surface between the workpiece and the cup, thereby improving the stability and reliability of the fixation. Each suction hole is connected to one or more vacuum tubes via an internal channel. The vacuum tube is a key component connecting the cup to the vacuum pump, responsible for extracting the air from the cup to create a vacuum. The vacuum pump is a key device for generating a vacuum. When the vacuum pump is activated, it extracts the air from the cup through the vacuum tube, creating a pressure environment below atmospheric pressure within the cup. This allows the external atmospheric pressure to press the workpiece tightly against the cup, achieving a secure fixation.

[0013] Optionally, a coil is provided inside the electric suction cup, and the coil is connected to a battery.

[0014] The electric suction cup contains one or more electromagnetic coils. These coils are typically made of insulated copper wire wound around an iron or magnetic core. When current passes through the coils, a magnetic field is generated, causing the electric suction 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, providing the necessary current to activate the coils. The battery pack design should take into account capacity, charging time, and safety to ensure long-term stable operation.

[0015] Optionally, a matching structure of a circular groove and a circular protrusion is provided between the turntable and the drag plate, and the matching structure is provided with a bearing.

[0016] The matching structure of the circular groove and protrusion ensures precise alignment and stable rotation of the turntable on the carriage. This design effectively prevents the turntable from shifting or shaking during rotation, improving machining accuracy. Bearings are located within the matching structure of the circular groove and protrusion. The bearings reduce friction and ensure smooth and stable rotation of the turntable. Common bearing types include ball bearings and plain bearings.

[0017] Optionally, the outer ring of the turntable is provided with an annular step structure, and the outer ring of the carriage is provided with an annular groove structure. The annular step structure cooperates with the annular groove structure and an axial contact bearing is provided in the middle.

[0018] The annular step structure provides a precise positioning surface, ensuring alignment between the turntable and the carriage. The ring groove structure cooperates with the annular step structure of the turntable to ensure stable positioning of the turntable on the carriage. The axial contact bearing reduces axial friction, ensuring smooth and low-noise rotation of the turntable.

[0019] Optionally, the workbench is installed on the bed, which is provided with an X-axis linear guide and an X-axis screw. The X-axis screw is connected to an X-axis servo motor, and the carriage is provided with a groove to slide with the X-axis linear guide.

[0020] The bed serves as the foundational framework of the entire machine, supporting key components such as the worktable and columns. The X-axis linear guideway provides precise guidance for the carriage along the X-axis, ensuring linear motion. The X-axis leadscrew rotates to convert the servo motor's rotational motion into linear motion for the carriage. The X-axis servo motor provides precise rotational power, enabling precise position control of the carriage via a controller. The carriage supports the turntable and workpiece, moving along the X-axis to precisely position the workpiece.

[0021] Optionally, the grinding wheel is fixed to the main shaft, the main shaft is connected to the output end of the main shaft servo motor, the main shaft is fixed to the movable seat outside, the movable seat is slidably connected to the Z-axis linear guide rail and is connected to the Z-axis screw, and the Z-axis screw is connected to the Z-axis servo motor.

[0022] Grinding wheels are used to grind or thin workpiece surfaces. The spindle provides the grinding wheel with rotational power, ensuring stable rotation. The spindle servo motor provides precise rotational power, enabling precise control of the grinding wheel through a controller. The moving base supports the spindle and grinding wheel, moving along the Z-axis to achieve precise positioning of the grinding wheel. The Z-axis linear guide provides precise guidance for the moving base along the Z-axis, ensuring linear motion. The Z-axis leadscrew rotates to convert the rotational motion of the Z-axis servo motor into linear motion of the moving base. The Z-axis servo motor provides precise rotational power, enabling precise position control of the moving base through a controller.
