Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, and in particular to a dual-station tipping bucket magnetic tumbler. Background Technology

[0002] A magnetic tumbler polishing machine, also known as a magnetic abrasive polishing machine, is a surface treatment device that uses a magnetic field to drive stainless steel magnetic needles at high speed to deburr, polish, and clean workpieces. Its working principle involves placing the workpiece, grinding needles, and polishing fluid together in a non-magnetic container. An alternating magnetic field generated below the container drives the magnetic needles to undergo disordered, high-speed collisions and friction, achieving precision machining of the workpiece surface.

[0003] Existing magnetic tumbler polishing machines have the following shortcomings in practical applications: First, traditional equipment is mostly designed for a single workstation. After polishing a batch of workpieces, the machine needs to be stopped and the heavy plastic buckets need to be manually moved out of the work area for emptying and material replacement, resulting in long auxiliary time, low production efficiency, and high labor intensity for workers. Second, although some equipment has an emptying function, it suffers from complex structure and poor stability, and often fails to achieve automatic separation of polishing fluid, workpieces, and grinding needles, requiring an additional screening process, which significantly prolongs the production process and increases production costs. Summary of the Invention

[0004] This application addresses the shortcomings of the prior art by providing a dual-station tipping bucket magnetic tumbler, which features a high degree of automation, adjustable magnetic force, and the ability to perform screening.

[0005] The technical solution adopted in this invention is as follows: A dual-station tipping bucket magnetic tumbling machine includes: Rack base, which is configured to provide the overall frame and mounting foundation for the equipment; The frame base has a central platform for placing items, and magnetic rolling and polishing pre-reserved positions on both sides. A screening unit, positioned above a platform, is configured to separate waste liquid from workpieces. Two magnetic tumbling polishing units are provided, each set in a corresponding magnetic tumbling polishing reserved position, and are configured to perform magnetic tumbling polishing on the workpiece. A plastic bucket, positioned above the magnetic tumbling unit, is configured to hold stainless steel needles, polishing fluid, and workpieces. The flipping units, each located on both sides of the corresponding magnetic tumbling unit, are configured to clamp and tilt the plastic buckets onto the screening unit.

[0006] Furthermore, the magnetic tumbling and polishing unit includes a housing and two guide rails spaced apart within the housing. It also includes a rotating magnetic disk assembly, a lifting mounting frame, and a drive assembly for reciprocating left and right movement of the rotating magnetic disk assembly. The lifting mounting frame is detachably connected to both the rotating magnetic disk assembly and the guide rails. The lifting mounting frame includes an upper mounting plate, two strip plates, and four adjustable support rods arranged in a rectangular array. The upper end of each adjustable support rod is connected to the upper mounting plate, and the lower end is connected to the strip plates. The drive assembly includes a motor, a disk connected to the motor's output shaft, and a connecting rod. One end of the connecting rod is hinged to an off-center point of the disk, and the other end is hinged to the lifting mounting frame. The lifting mounting frame is detachably connected to both the rotating magnetic disk assembly and the guide rails.

[0007] Furthermore, the rotating magnetic disk assembly includes a rotating motor and a circular support plate connected to the output shaft of the rotating motor. The circular support plate has a plurality of blind holes arranged in a ring array, and a ring magnet is disposed in each blind hole. The ring magnet is connected to the circular support plate by a screw.

[0008] Furthermore, the adjusting support rod includes a screw and three nuts screwed onto the screw. The lower end of the screw is threaded to the strip plate, and the upper end passes through the upper mounting plate. The upper mounting plate is axially limited by two nuts above the screw, and the nut at the bottom of the screw is in close contact with the upper surface of the strip plate.

[0009] Furthermore, the flipping unit includes two sets of raised seats mounted on the frame base platform. Each raised seat is provided with a bearing seat, and each bearing seat is provided with a rotating shaft. The two sets of rotating shafts are coaxially connected with clamps, which clamp the plastic bucket. One set of rotating shafts is connected to a servo motor at its input end.

[0010] Furthermore, the screening unit includes a discharge bin, the bottom plane of which is a screen, and a variable diameter cavity is formed at the front of the discharge bin, with a first discharge port at the front end of the variable diameter cavity.

[0011] Furthermore, a height difference section is formed at the front of the variable diameter cavity near the first discharge port, and a second discharge port is opened downward at the front of the variable diameter cavity. An intercepting net is tied to the opening of the second discharge port, and the aperture of the intercepting net allows stainless steel needles to pass through.

[0012] Furthermore, the cavity of the first discharge port has an inclined angle, and a sliding port is provided near the variable diameter cavity of the first discharge port to facilitate the passage of the workpiece. The inclined angle of the sliding port is opposite to that of the first discharge port.

[0013] The advantages of this invention over the prior art are as follows: 1) By setting up a dual-station magnetic tumbling polishing unit, alternating operation is achieved. While one station is performing tumbling polishing, the other station can perform loading and unloading operations, which significantly improves production efficiency. 2) By combining the tilting unit and the screening unit, the automatic dumping and solid-liquid separation of the processed materials are realized, eliminating the need for manual handling of heavy plastic buckets, reducing labor intensity. In addition, the screening unit can effectively separate the workpiece, stainless steel needles and grinding liquid, which is convenient for subsequent processing. 3) The magnetic roller polishing unit integrates a lifting mounting frame and a reciprocating drive assembly. By adjusting the support rods, the distance between the rotating magnetic disk assembly and the bottom of the plastic bucket can be changed, thereby precisely adjusting the magnetic force to meet the processing needs of workpieces of different materials and sizes. At the same time, the drive assembly drives the magnetic disk to move back and forth, expanding the range of motion of the magnetic needle and improving the uniformity and effect of polishing.

Detailed Implementation

[0016] The technical solution of the present invention will be further described in a non-limiting manner below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1 to 3 As shown, the present invention provides a dual-station tipping bucket magnetic tumbling machine, including a frame base 1. The frame base 1 provides the overall frame and installation foundation of the equipment; a placement platform 2 is provided at the center of the frame base 1, which is used to place and connect the screening unit 10; magnetic tumbling reserved positions are symmetrically arranged on both sides of the frame base 1 for installing magnetic tumbling units 3.

[0018] In one embodiment of the present invention, two magnetic polishing units 3 are provided, each installed in a corresponding magnetic polishing reserved position, for performing magnetic polishing processing on the workpiece. Specifically, as shown in the figure... Figure 2As shown, the magnetic tumbling and polishing unit 3 includes a housing and two guide rails spaced apart within the housing. It also includes a rotating magnetic disk assembly, a lifting mounting frame, and a drive assembly for reciprocating left and right movement of the rotating magnetic disk assembly. The lifting mounting frame is detachably connected to both the rotating magnetic disk assembly and the guide rails, allowing the lifting mounting frame to move smoothly along the guide rails.

[0019] In one embodiment of the present invention, the lifting mounting frame includes an upper mounting plate, two strip plates, and four adjustable support rods. The adjustable support rods are arranged in a rectangular array, with their upper ends connected to the upper mounting plate and their lower ends connected to the strip plates. The strip plates are slidably connected to the guide rail 4 via sliders or screws. Each adjustable support rod includes a screw and three nuts screwed onto the screw. The lower end of the screw is threaded to the strip plate, and its upper end passes through the upper mounting plate. The upper mounting plate is axially limited by the two nuts above the screw, and the nut at the bottom of the screw is in close contact with the upper surface of the strip plate. By loosening the two nuts above, rotating the screw, or adjusting its extension length, the distance between the upper mounting plate and the strip plates can be changed, thereby adjusting the height of the entire rotating magnetic disk assembly and achieving precise adjustment of the magnetic force.

[0020] In one embodiment of the invention, the drive assembly includes a motor, a disk connected to the motor output shaft, and a connecting rod. One end of the connecting rod is hinged to an off-center point of the disk, and the other end is hinged to a lifting mounting frame. The motor is fixed to the equipment housing via an L-shaped mounting plate. When the motor drives the disk to rotate, the connecting rod converts the circular motion into reciprocating linear motion of the lifting mounting frame along the guide rail, thereby causing the rotating magnetic disk assembly to translate left and right, expanding the coverage of the magnetic field, making the movement of the stainless steel needles inside the plastic bucket more disordered and uniform, and improving the polishing effect.

[0021] In one embodiment of the present invention, the rotating magnetic disk assembly includes a rotary motor and a circular support plate connected to the output shaft of the rotary motor. The circular support plate has a plurality of blind holes arranged in a ring array, and a ring magnet is disposed within each blind hole. The ring magnet is connected to the circular support plate by a screw. The rotary motor drives the circular support plate to rotate at high speed, generating an alternating magnetic field, which in turn moves the stainless steel needle inside the plastic bucket 9 above it.

[0022] It should be noted that the above-mentioned magnetic rolling and polishing unit 3 is a conventional module in this field, and the technical solution described in the announcement number CN210281641U can be adopted. This application will not repeat it.

[0023] In one embodiment of the present invention, such as Figure 1 and Figure 3As shown, the plastic bucket 8 (the installation position is shown in the figure, the bucket body is not shown) is positioned above the magnetic polishing unit 3, specifically above the rotating magnetic disk assembly, and is used to hold the stainless steel needles, polishing fluid, and workpieces to be processed. Two flipping units 9 are provided, corresponding to the two magnetic polishing units 3 respectively. Each flipping unit 9 is located on both sides of the corresponding magnetic polishing unit 3, used to clamp and tilt the plastic bucket 8 onto the screening unit 10. Specifically, the flipping unit 9 includes two sets of raised seats 91 mounted on the platform of the frame base 1. Bearing seats 92 are mounted on the raised seats 91, and rotating shafts (not shown in the figure) are installed inside the bearing seats 92. The two sets of rotating shafts are coaxially connected by clamps 94, which clamp and fix the plastic bucket 8 to the side wall. The input end of one set of rotating shafts is connected to a servo motor via a reducer. Once processing is complete, the servo motor starts and drives the rotating shaft to rotate, which in turn causes the plastic bucket 8 to rotate and tilt around the shaft axis via the clamp 94, pouring the materials inside (workpiece, stainless steel needle, grinding fluid) into the screening unit 10 below.

[0024] In one embodiment of the present invention, a screening unit 10 is disposed above the placement platform 2 of the frame base 1, and is used to separate waste liquid and workpieces. The screening unit 10 includes a discharge bin 101, the bottom plane of which is a screen 102. When the mixed material falls into the discharge bin 101, the grinding liquid passes through the screen 102 and flows into the collection tank below (not shown in the figure), while the workpiece and stainless steel needle remain on the screen 102 and slide forward. The front part of the discharge bin 101 is formed with a variable diameter cavity 103, and the front end of the variable diameter cavity 103 is provided with a first discharge port 104. A height difference section is formed at the front part of the variable diameter cavity 103 near the first discharge port 104, and the front part of the variable diameter cavity 103 opens downward to a second discharge port 106. An intercepting mesh 107 is tied to the opening of the second discharge port 106. The aperture of the intercepting mesh 107 allows stainless steel needles to pass through but intercepts workpieces. The first discharge port 104 has an inclined angle in its cavity section, and a sliding port 108 is provided near the variable diameter cavity 103 of the first discharge port 104 to facilitate the passage of the workpiece. The inclined angle of the sliding port 108 is opposite to that of the first discharge port 104.

[0025] During the screening process, the tail end of the feed hopper is manually lifted or lifted by a cylinder. The stainless steel needles first slide into the variable diameter chamber 103. When passing through the high and low drop section 105, due to inertia and gravity, the lighter and smaller stainless steel needles fall into the second discharge port 106 and are blocked by the intercepting net 107. The workpieces continue to slide along the sliding port 108 to the first discharge port 104 and are finally discharged and collected, thus realizing the automatic separation of the workpieces and the stainless steel needles.

[0026] In summary, the dual-station tipping bucket magnetic tumbler provided by this invention achieves alternating continuous production through a dual-station design. It utilizes an automatic tipping unit 9 and a screening unit 10 to automatically tilt and separate materials. Furthermore, it incorporates adjustable magnetic force and a translational magnetic disk technology, which significantly improves production efficiency, reduces labor costs, and enhances the equipment's processing adaptability and polishing quality.
