Gear machining cleaning apparatus

Abstract

This utility model relates to the field of gear processing and cleaning technology, specifically to a gear processing and cleaning device, including a placement tank and a cleaning tank nested inside it. The top of the placement tank is provided with a limiting plate, and four positioning pins are vertically installed on the bottom of the plate. The tank body is evenly distributed with elongated filter grooves, and the bottom of the tank is formed as an integral arc plate. The opening end of the cleaning tank is provided with a limiting groove and a corresponding positioning hole. During assembly, the placement tank is embedded into the cleaning tank, the limiting plate is engaged in the limiting groove, and the positioning pins are inserted into the positioning holes to achieve bidirectional fixation in both the circumferential and axial directions. In the working state, the magnetic beads inside the tank move at high speed under the action of an external driving magnetic field, continuously colliding with the gear surface to remove burrs and oil stains. The filter groove structure does not affect the movement trajectory of the magnetic beads. When the placement tank is lifted after cleaning, the arc plate guides the waste liquid to flow to the side wall, and the liquid is discharged into the cleaning tank cavity through the filter groove. The magnetic beads and gears are effectively blocked and retained in the placement tank by the filter groove. This achieves automatic separation of gears and cleaning media, eliminating the operational risks of manual groping to retrieve parts.

Description

Technical Field

[0001] This utility model relates to the field of gear processing and cleaning technology, and in particular to a gear processing and cleaning device. Background Technology

[0002] Traditional gear cleaning typically employs a simple rinsing method. Operators place the gears in an open container or tank and directly rinse them with water or cleaning fluid. While intuitive, this method has significant shortcomings. The core issue is that relying solely on fluid force is insufficient to thoroughly remove stubborn oil, cutting fluid residue, and debris adhering to the complex surfaces of gears, especially in the tooth gaps and tiny recesses. The rinsing process often only cleans the surface and easily accessible areas, failing to deeply clean the tooth profile or remove any microburrs that may remain after machining, resulting in limited and incomplete cleaning. Furthermore, this process is highly dependent on manual operation, time-consuming, and inefficient.

[0003] To overcome the shortcomings of basic rinsing methods, a magnetic-assisted cleaning technique has been applied. The core of this technology involves placing magnetic beads (such as stainless steel balls or specialized cleaning steel balls) attracted by a magnetic field next to or under the gears. These beads are then driven by an external rotating magnet or electromagnetic field to move at high speed around the gears within a sealed container. Driven by the magnetic field, the beads continuously collide and rub against the various surfaces and tooth gaps of the gears. This physical collision and scraping action significantly improves the removal of oil and impurities, while the abrasive effect from the bead movement effectively removes burrs from the tooth surfaces. This magnetically driven cleaning method significantly improves cleaning efficiency and cleanliness, and also possesses a certain finishing function.

[0004] However, this highly efficient magnetic bead drive method brings new technical challenges: to ensure that the magnetic beads can move smoothly and unimpeded at high speed and evenly impact the gears during the cleaning process, these devices typically cannot accommodate traditional filter baskets or mesh structures. Any solid mesh, fence, or filter basket structure may obstruct or restrict the movement trajectory of the magnetic beads, increase frictional resistance, or even cause the magnetic beads to get stuck, accumulate, or violently collide at the mesh edges, losing some kinetic energy, ultimately leading to poor cleaning results, reduced efficiency, or increased equipment vibration. Therefore, in existing magnetically driven cleaning equipment, gears and magnetic beads are usually placed directly into the fixed cleaning chamber of the equipment for cleaning. After cleaning, operators have to manually retrieve the gears and scattered magnetic beads from the closed chamber filled with dirty liquid. This process is not only extremely inconvenient, increasing operational complexity and downtime, but also carries the risk of being scratched by residual liquid or the internal structure of the equipment, especially when dealing with a large number of gears or gears with fine burrs on their surfaces. Utility Model Content

[0005] The purpose of this utility model is to provide a gear processing and cleaning equipment to solve the problem that when using magnetic suction to drive cleaning, the lack of a dedicated filter structure leads to the need for manual groping to remove parts after cleaning, which also poses a safety hazard.

[0006] To achieve the above objectives, this utility model provides a gear processing and cleaning device, including a placement bucket. A limiting plate is fixedly installed at the top of the placement bucket, and four positioning pins are installed at intervals at the bottom of the limiting plate. Several elongated filter grooves are spaced apart on the radially outer side of the placement bucket. An arc-shaped plate is fixedly installed at the bottom of the placement bucket. The placement bucket is embedded inside a cleaning mechanism. The cleaning mechanism includes a cleaning bucket. A limiting groove is opened at the opening of the cleaning bucket, and four positioning holes are spaced apart in the limiting groove. The placement bucket is embedded inside the cleaning bucket. When the placement bucket is embedded, the positioning pins are respectively inserted into the positioning holes.

[0007] The cleaning tank has a discharge connector installed through it on the lower radial side, and an assembly plate is fixedly installed at the bottom of the cleaning tank. The assembly plate is installed on the top of the support block by bolts.

[0008] The support block has a rotating groove at its top, a rotating disk is rotatably installed in the rotating groove, a magnetic block is fixedly installed at the top of the rotating disk, and a rotating shaft is installed through the center of the magnetic block and the rotating disk.

[0009] The bottom end of the rotating shaft passes through the center of the rotating groove via a bearing and is connected to the output end of the rotating motor. A fixing plate is fixedly installed on the edge housing of the output end of the rotating motor.

[0010] The fixing plate is installed on the top surface of the maintenance groove by bolts. The maintenance groove is opened on the radially outer side below the support block. A fixing plate is fixedly installed at the bottom end of the support block.

[0011] The fixing plate has several fixing holes spaced apart, and bolts pass through the fixing holes to fix it to the ground.

[0012] This utility model discloses a gear processing and cleaning device, comprising two separable nested parts: a placement tank and a cleaning tank. A limiting plate is fixedly connected to the top of the placement tank, and four positioning pins are vertically installed on the bottom surface of the limiting plate. Multiple through-type elongated filter grooves are evenly opened on the circumferential side wall of the placement tank. The bottom of the tank is stamped to form an integrally concave arc-shaped plate structure. An annular limiting groove is provided at the opening end of the cleaning tank, and positioning holes corresponding to the positions of the positioning pins are opened in the groove.

[0013] When the placement tank is embedded inside the cleaning tank, axial constraint is achieved by the overlap of the edge of the limiting plate and the limiting groove. At the same time, four positioning pins are precisely inserted into the positioning holes to form circumferential positioning, ensuring that the two tanks remain stably aligned during the cleaning process. The long strip-shaped filter groove design on the side wall of the placement tank allows the liquid to flow freely during cleaning but prevents the magnetic beads and gears from leaking out.

[0014] This core structure achieves two key effects: First, during cleaning, the external drive device (such as a rotating magnetic field) can penetrate the barrel wall to drive the magnetic beads inside the placement barrel to move at high speed, unimpeded by the filter tank structure, maintaining efficient cleaning and deburring functions; Second, when the placement barrel is lifted after the operation is completed, the arc plate at the bottom of the barrel naturally guides the liquid to the side wall to collect, and the cleaning waste liquid quickly flows back to the cleaning barrel through the filter tank, while the magnetic beads and gears are physically trapped in the placement barrel by the filter tank. This eliminates the operational risks of manually groping to retrieve parts in traditional magnetic cleaning equipment, and achieves one-step safe recycling of gears and consumables.

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-4 .

[0023] This utility model provides a gear processing and cleaning device. A fixed disk 120 serves as the device's basic support structure, with several evenly distributed fixing holes 121 on its surface. Bolts are used to achieve rigid anchoring of the entire device to the ground. A support block 111 is vertically welded to the center of the fixed disk 120. A rectangular maintenance groove 118 is formed on the lower radially outer side of the support block 111 to accommodate the drive unit. A rotating motor 116 is fixed to the top surface of the maintenance groove 118 by bolts through a fixing plate 117. Its output end extends upwards through the top plane of the support block 111. The output end of the rotating motor 116 is connected to a vertically arranged rotating shaft 115. The rotating shaft 115 extends upward and penetrates the interior of the support block 111. A cylindrical rotating groove 112 is formed at the top of the support block 111. A horizontally rotatable rotating disk 113 is installed in the groove via bearings. The center of the top surface of the rotating disk 113 is fastened to the top of the rotating shaft 115 to achieve torque transmission. Annular magnetic blocks 114 are embedded on the edge of the disk to generate a rotating magnetic field. The top of the support block 111 is fixed to the assembly disk 110 with bolts. This disc-shaped structure serves as the mounting base for the cleaning mechanism 122. The cleaning tank 106 serves as the core container, with its bottom welded to the center of the top surface of the assembly disk 110. The side wall of the cleaning tank 106... A through-hole discharge connector 109 is installed for waste liquid diversion; an annular limiting groove 107 is machined on the edge of the barrel opening, and four positioning holes 108 are evenly distributed on the bottom of the groove. The placement barrel 101 serves as a detachable inner liner, and its outer diameter is precisely matched with the inner cavity of the cleaning barrel 106. A limiting plate 102 is welded to the top of the placement barrel 101, and four positioning pins 103 are vertically installed on the bottom of the plate. When the placement barrel 101 is inserted into the cleaning barrel 106, the positioning pins 103 are inserted into the positioning holes 108 to form circumferential limiting, while the edge of the limiting plate 102 is engaged with the limiting groove 107 to achieve axial constraint; several elongated filter grooves 104 are opened on the side wall of the placement barrel 101, and their width is... Designed with a diameter smaller than that of the magnetic beads, the bottom of the bucket is stamped into an arc-shaped plate 105 structure, the curvature of which facilitates the guiding flow of liquid. In actual operation, the gear and magnetic beads are loaded into the placement bucket 101 and then embedded into the cleaning bucket 106. When the magnetic block 114 rotates, it drives the magnetic beads to move through the magnetic field, realizing gear collision cleaning and liquid swirling. When the placement bucket 101 is lifted, the arc-shaped plate 105 guides the waste liquid through the filter tank 104 back to the cleaning bucket 106, while the magnetic beads and gears are physically blocked by the filter tank 104 and retained in the bucket. The entire structure achieves automation of the cleaning process and high efficiency of solid-liquid separation through precise spatial matching and magnetic transmission.

[0024] Working principle: Before starting the operation, the operator first places the gear to be processed and several magnetic beads with a diameter larger than the width of the filter tank 104 into the placement tank 101. Then, the placement tank 101 is embedded into the cleaning tank 106. At this time, the limiting plate 102 at the top of the placement tank 101 is precisely engaged with the limiting groove 107 at the opening of the cleaning tank 106. The four positioning pins 103 are simultaneously inserted into the corresponding positioning holes 108 to ensure that the placement tank 101 is stably limited and to prevent displacement or shaking during the cleaning process. After positioning, an appropriate amount of cleaning liquid is injected into the placement tank 101 until the gear is submerged. Then, the rotating motor 116 is started, and its output end drives the rotating shaft 115 to rotate, which drives the rotating disk 113 fixed at the top of the rotating shaft 115 to rotate synchronously. The magnetic block 114 is embedded on the rotating disk 113 and rotates together with it. The generated rotating magnetic field acts on the gear. The magnetic beads inside the placement tank 101 move at high speed under magnetic drive, creating the following synergistic effect: On the one hand, the circular motion of the magnetic beads agitates the cleaning fluid, generating a strong vortex that allows the liquid to thoroughly wash the gear surface and tooth gaps; on the other hand, the high-speed moving magnetic beads continuously impact the gear surface, removing oil, debris, and burrs through mechanical friction. This dual effect significantly improves cleaning efficiency and surface treatment quality, while avoiding the damage risk of traditional manual deburring. After the cleaning process is completed, the motor stops running. When the operator lifts the placement tank 101, the arc-shaped plate 105 at its bottom guides the residual cleaning fluid to flow rapidly to the side wall. The liquid is efficiently discharged back into the cleaning tank 106 through the radially distributed elongated filter tanks 104, while the magnetic beads and gears, because their size is larger than the width of the filter tanks 104, are reliably retained in the placement tank 101. This process enables rapid and automatic separation of liquid media from solids. Operators can directly remove gears and magnetic beads from the placement tank 101 without having to search and retrieve them from the cleaning tank 106. The entire system, through a combination of mechanisms such as limit insertion, magnetic drive, eddy current flushing, collision cleaning, and arc bottom guiding, ensures cleaning depth and deburring effect while effectively solving the pain points of material jamming and difficulty in manual removal in traditional basket structures, significantly improving operational safety and work efficiency.
