Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of grinding machines, and more specifically, to an automatic grinding machine for high-precision grinding. Background Technology

[0002] In the field of modern industrial precision manufacturing, the accuracy and quality of planar machining directly affect the performance of parts and the reliability of products. With the technological upgrading of industries such as aerospace, semiconductors, and precision molds, the requirements for the flatness, accuracy, and smoothness of planar surfaces are becoming increasingly stringent. Traditional manual grinding methods can no longer meet the needs of high-end manufacturing, making the development of high-performance fully automated grinding equipment a necessity for the industry.

[0003] Traditional grinding processes rely heavily on manual operation. Operators must hold tools and rely on experience to control the grinding force and direction, resulting in low production efficiency and significant quality fluctuations. For example, in the machining of optical components or precision molds, manual grinding makes it difficult to ensure consistency between different batches of workpieces, and the operation process is easily affected by factors such as operator fatigue and skill level, making it difficult to achieve micron-level precision control. In addition, manual operation also faces occupational health problems such as dust pollution and noise hazards, which contradicts the trend of green and automated development in modern industry.

[0004] Although some traditional grinding equipment has achieved mechanization improvements, it generally suffers from insufficient intelligence. Fixed-speed grinding tables cannot dynamically adjust process parameters according to workpiece material, easily causing surface damage to materials with large hardness differences. The lack of real-time detection and feedback mechanisms leads to delayed correction of grinding errors, often requiring multiple rework operations. With the surge in demand for high-precision components such as semiconductor wafers and precision bearings, the market urgently needs a fully automated grinding equipment capable of sub-micron precision control, compatible with various workpiece types, and equipped with intelligent parameter adjustment functions. This will improve production efficiency, ensure quality stability, and drive the precision manufacturing industry towards automation and intelligence. Utility Model Content

[0035] like Figures 1-5 As shown, it illustrates an automatic grinding machine for high-precision grinding in one embodiment of the present disclosure, comprising:

[0036] The main frame 1 and the truss 2 are fixed to the top of the main frame 1;

[0037] Feeding assembly 4 is disposed on the main frame 1 and the truss 2;

[0038] The rear frame 3 and the surface treatment component 5 are provided on the main frame 1.

[0039] The feeding assembly 4 includes a feeding rack 4-1 and a discharging rack 4-2. The feeding rack 4-1 and the discharging rack 4-2 are respectively fixed to the two side surfaces of the main frame 1. Positioning grooves 4-3 are provided on the surfaces of both the feeding rack 4-1 and the discharging rack 4-2. A pair of slide rails 4-4 are provided on the main frame 1, and a moving platform 4-5 is slidably connected to the slide rails 4-4. An installation groove 4-6 is provided on the surface of the moving platform 4-5. A suction cup bracket 4-13 is provided on the truss 2. A first lead screw 4-7 is provided on the main frame 1, and the first lead screw 4-7 is connected to the moving platform 4-5 via a threaded connection. A second lead screw 4-8 is installed inside the truss 2. A vertical frame 4-9 is slidably connected inside the truss 2. The vertical frame 4-9 is connected to the first lead screw 4-7 by a threaded connection. A third lead screw 4-10 is installed inside the vertical frame 4-9. A lifting platform 4-11 is slidably connected inside the vertical frame 4-9. The lifting platform 4-11 is connected to the third lead screw 4-10 by a threaded connection. A vacuum pump 4-12 is installed on the lifting platform 4-11. A suction cup frame 4-13 is fixed to the bottom of the lifting platform 4-11. The suction end of the vacuum pump 4-12 is connected to the suction cup frame 4-13.

[0040] In some examples, in the high-precision grinding of sheet metal, a loading assembly 4 is designed to achieve automated loading and unloading. This assembly uses the feed rack 4-1 and the discharge rack 4-2 fixed on both sides of the main frame 1 as material storage points. The positioning grooves 4-3 on the surfaces of the main frame 1 and the auxiliary frame serve as material positioning references. A pair of slide rails 4-4 on the main frame 1 provide sliding tracks for the moving table 4-5. The first lead screw 4-7 is threadedly engaged with the moving table 4-5. By driving the first lead screw 4-7 to rotate through the motor, the moving table 4-5 can be controlled to move horizontally along the slide rails 4-4, realizing the lateral transfer of materials between the feed rack 4-1, the processing area, and the discharge rack 4-2.

[0041] The second lead screw 4-8 installed inside the truss 2 is threadedly connected to the vertical frame 4-9. Driving the second lead screw 4-8 allows the vertical frame 4-9 to move up and down along the truss 2. The third lead screw 4-10 inside the vertical frame 4-9 is threadedly engaged with the lifting platform 4-11. Controlling the rotation of the third lead screw 4-10 enables the lifting platform 4-11 to move precisely up and down in the vertical direction. The vacuum pump 4-12 installed on the lifting platform 4-11 is connected to the suction cup frame 4-13 at the bottom. When the vacuum pump 4-12 is started, the suction cup frame 4-13 generates suction force, which can adsorb the workpiece. Through the coordinated movement of the first lead screw 4-7, the second lead screw 4-8, and the third lead screw 4-10, the suction cup frame 4-13 can move precisely to the feeding rack 4-1 to pick up the workpiece, then move it to the processing area to place the workpiece, and after processing, transport the workpiece to the unloading rack 4-2, thereby realizing automated loading and unloading.

[0042] Through the coordinated operation of components such as the feeding rack 4-1, the discharging rack 4-2, the positioning groove 4-3, the slide rail 4-4, the moving table 4-5, the mounting groove 4-6, the suction cup frame 4-13, the first lead screw 4-7, the second lead screw 4-8, the third lead screw 4-10, the lifting platform 4-11, and the vacuum pump 4-12, the loading assembly 4 realizes the function of automated loading and unloading of materials via suction cups.

[0043] like Figures 1-5 As shown in the figure, the surface treatment component 5 in this embodiment includes a pair of first telescopic cylinders 5-1. The first telescopic cylinders 5-1 are respectively fixed at both ends of the top of the rear frame 3. The output end of the first telescopic cylinder 5-1 is connected to a crossbeam 5-2. A fourth lead screw 5-3 is provided inside the crossbeam 5-2. A sturdy seat 5-4 is slidably connected to the surface of the crossbeam 5-2. The sturdy seat 5-4 and the fourth lead screw 5-3 are connected by a threaded engagement. A grinding table 5-5 is provided at the bottom of the sturdy seat 5-4. A transverse slide rail 5-6 is provided on the side surface of the crossbeam 5-2. The sturdy seat 5-4 is slidably connected to the transverse slide rail 5-6. A pair of first telescopic cylinders 5-1 are provided at the bottom of the rear frame 3. Two telescopic cylinders 5-7 are connected to a connecting frame 5-8 at their output ends. A sand-laying pipe 5-9 is rotatably connected inside the connecting frame 5-8. A pushing auger 5-10 is installed inside the sand-laying pipe 5-9. Several dispersing outlets 5-11 are opened at the bottom of the sand-laying pipe 5-9. A sealing cover 5-12 is rotatably connected to the inner end face of the connecting frame 5-8. The sealing cover 5-12 is rotated by a motor and fits against the surface of the sand-laying pipe 5-9. A cleaning roller 5-13 is rotatably connected inside the connecting frame 5-8. The cleaning roller 5-13 is rotated by a motor. A recycling box 5-14 is provided at the bottom of the main frame 1.

[0044] In some examples, a surface treatment component 5 is designed to achieve high-precision grinding and post-grinding cleaning of the workpiece surface. This component uses the first telescopic cylinder 5-1 fixed at both ends of the top of the rear frame 3 as a power source. The cross frame 5-2 connected to its output end can move in the vertical direction. The fourth lead screw 5-3 inside the cross frame 5-2 is threadedly engaged with the stabilizing seat 5-4. Driving the fourth lead screw 5-3 can make the stabilizing seat 5-4 move horizontally along the cross frame 5-2, thereby driving the grinding table 5-6 to move left and right repeatedly, and to grind the workpiece surface with the grinding sand.

[0045] The connecting frame 5-8 connected to the output end of the second telescopic cylinder 5-7 at the bottom of the rear frame 3 can drive the sand-spreading pipe 5-9 and the cleaning roller 5-13 to rise and fall. The pusher auger 5-10 in the sand-spreading pipe 5-9 pushes the grinding sand to the outlet 5-11 at the bottom of the pipe, so that the grinding sand is evenly covered on the surface of the workpiece. The sealing cover 5-12 inside the connecting frame 5-8 is controlled by a motor to rotate and can be opened and closed to control the spreading range of the grinding sand. The cleaning roller 5-13 is driven by a motor to rotate. After grinding is completed, the cleaning roller 5-13 can clean up the remaining grinding sand.

[0046] Through the coordinated operation of components such as the first telescopic cylinder 5-1, the crossbeam 5-2, the fourth lead screw 5-3, the stabilizing seat 5-4, the high-speed motor 5-5, the grinding table 5-6, the second telescopic cylinder 5-7, the connecting frame 5-8, the sand-laying pipe 5-9, the pushing auger 5-10, the sealing cover 5-12, the cleaning roller 5-13, and the recycling box 5-14, the surface treatment component 5 realizes the functions of covering the workpiece surface with grinding sand, grinding, and cleaning the grinding sand after grinding.

[0047] For example, such as Figure 1 As shown, flat grooves 6 are provided at both ends of the surface of the mobile platform 4-5, and the flat grooves 6 are connected to the interior of the mounting groove 4-6.

[0048] In some examples, the flat groove 6 makes both ends of the surface of the moving stage 4-5 lower than the surface of the plate, so that the grinding stage 5-6 can grind the surface of the plate without dead angles.

[0049] In actual use: The workpiece is placed in the positioning slot 4-3 of the feed rack 4-1. The vacuum pump 4-12 drives the suction cup frame 4-13 to pick up the workpiece. The first lead screw 4-7 drives the moving table 4-5 to move along the slide rail 4-4 to below the feed rack 4-1. The second lead screw 4-8 and the third lead screw 4-10 work together to control the vertical frame 4-9 and the lifting platform 4-11 to descend, accurately placing the workpiece in the mounting slot 4-6 of the moving table 4-5. The positioning slot 4-3 ensures the workpiece is positioned. The moving table 4-5 moves the workpiece to the grinding area. At the same time, the second telescopic cylinder 5-7... The connecting frame 5-8 is driven down, and the auger 5-10 pushes the abrasive sand to be evenly spread from the outlet 5-11. The cleaning roller 5-13 pushes the sand layer flat. Then, the first telescopic cylinder 5-1 of the surface treatment component 5 pushes the cross frame 5-2 down. The fourth screw 5-3 controls the stabilizing seat 5-4 to move left and right repeatedly, so that the grinding table 5-6 generates a grinding path to grind the surface of the plate. After grinding, during the back movement, the cleaning roller 5-13 sweeps the abrasive sand into the recycling box 5-14. The suction cup frame 4-13 then transfers the workpiece to the discharge frame 4-2.
