Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing, specifically a surface deburring structure for automotive parts. Background Technology
[0002] In the automotive parts manufacturing industry, the surface quality of ring-shaped parts (such as flanges and gear rings) directly affects the assembly accuracy and operational reliability of the entire vehicle. Grinding and deburring are key processes to ensure product quality. Currently, the industry generally adopts a staged, equipment-based approach for grinding the inner and outer surfaces of ring-shaped parts, which leads to significant efficiency bottlenecks and cost waste.
[0003] Most existing grinding devices cannot achieve simultaneous grinding of the inner and outer surfaces of ring-shaped parts. In actual operation, the part is usually fixed in a fixture first, and after the outer surface is ground, it is manually disassembled, flipped, and then re-clamped to another station for inner surface grinding. This step-by-step operation not only prolongs the processing cycle of a single part and increases labor costs, but the frequent clamping process may also introduce positioning errors, affecting grinding accuracy and surface consistency.
[0004] Therefore, developing a surface burr treatment structure that can simultaneously grind internal and external surfaces and is compatible with various sizes of ring-shaped parts has become an important issue that urgently needs to be addressed in the automotive parts manufacturing industry. Utility Model Content
[0005] The purpose of this invention is to provide a surface burr treatment structure for automotive parts to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A surface deburring structure for automotive parts includes a processing table with four strip-shaped holes arranged in a circular array. A first slider and a second slider are slidably disposed within each of the four holes. A fixed frame is mounted on each of the first and second sliders. An inner grinding roller is mounted on two of the first sliders in the same diameter direction, and an outer grinding roller is mounted on two of the second sliders in the same direction. The inner and outer grinding rollers are driven by a grinding motor mounted on the fixed frame. An adjustment component is provided on the processing table to adjust the distance between the inner and outer grinding rollers. In the other two directions, an inner drive roller is mounted on the first slider, driven by a drive motor mounted on the fixed frame. A drive assembly is also provided on the processing table to provide power for the synchronous movement of the multiple first sliders towards or away from the center of the processing table.
[0008] As a further embodiment of this utility model: an outer drive roller is also installed on the second slider corresponding to the position of the inner drive roller in the strip hole, a first screw is rotatably installed on one side of the second slider, the first screw is threadedly installed on the processing table, and a first knob is installed at the end of the first screw.
[0009] As a further embodiment of this utility model: the driving assembly includes a second screw that is vertically rotatably mounted on the processing table, a movable part that is threaded onto the second screw, and a plurality of push-pull rods that are hinged onto the movable part. A second knob is installed at the top of the second screw. The plurality of push-pull rods are arranged in a one-to-one correspondence with a plurality of first sliders, and the push-pull rods are hinged to the side of the first sliders.
[0010] As a further embodiment of this utility model: the adjustment component includes a bidirectional lead screw rotatably mounted on the bottom surface of the machining table. The bidirectional lead screw is driven by a servo motor set on the bottom surface of the machining table. Screw sleeves are symmetrically mounted on the two threaded portions of the bidirectional lead screw, and a second slider is fixedly mounted on the screw sleeves.
[0011] As a further embodiment of this utility model: an extension platform is fixedly provided on the side of the first slider near the second slider, and multiple balls are installed on the extension platform.
[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0020] Example 1
[0021] Please see Figure 1-4 A surface deburring structure for automotive parts includes a processing table 1 with four strip-shaped holes 2 arranged in a circular array. Each of the four holes 2 has a first slider 3 and a second slider 4 slidably mounted therein. A fixing frame 5 is mounted on each of the first slider 3 and the second slider 4. An inner grinding roller 6 is mounted on two of the first sliders 3 in the same diameter direction, and an outer grinding roller 7 is mounted on two of the second sliders 4 in the same direction. The inner and outer grinding rollers 6 and 7 are driven by a grinding motor 8 mounted on the fixing frame 5. An adjustment assembly is provided on the processing table 1 to adjust the distance between the inner and outer grinding rollers 6 and 7. In the other two directions, an inner drive roller 9 is mounted on the first slider 3. The drive roller 9 is driven by the drive motor 10 mounted on the fixed frame 5. The processing table 1 is also equipped with a drive assembly, which provides power for the multiple first sliders 3 to move synchronously toward or away from the center of the processing table 1. When processing a ring-shaped part, the part is placed between the inner grinding roller 6 and the outer grinding roller 7. The drive assembly causes the first slider 3 to drive the inner grinding roller 6 and the inner drive roller 9 to move closer to the inner ring of the part. The adjustment assembly adjusts the spacing so that the outer grinding roller 7 fits against the outer ring. When the inner drive roller 9 rotates, the inner grinding roller 6 and the outer grinding roller 7 simultaneously grind the inner and outer surfaces of the part, greatly improving the grinding efficiency. At the same time, the adjustment assembly cooperates with the drive assembly to adapt to ring-shaped parts of different diameters, significantly improving the versatility of the device.
[0022] Example 2
[0023] Please see Figure 1 and Figure 2An outer drive roller 11 is also installed on the second slider 4 corresponding to the position of the inner drive roller 9 inside the strip hole 2. A first screw 12 is rotatably installed on one side of the second slider 4. The first screw 12 is threaded onto the processing table 1, and a first knob 13 is installed at the end of the first screw 12. When the drive assembly makes the inner drive roller 9 contact the inner surface of the part, turning the first knob 13 can drive the outer drive roller 11 to contact the outer ring of the part. The inner drive roller 9 and the outer drive roller 11 work together to further enhance the stability of the part when rotating and avoid the part shaking during the grinding process, which would affect the grinding effect.
[0024] Example 3
[0025] Please see Figure 1 and Figure 4 The drive assembly includes a second screw 14 vertically rotatably mounted on the processing table 1, a movable part 16 threaded onto the second screw 14, and multiple push-pull rods 17 hinged onto the movable part 16. A second knob 15 is mounted on the top of the second screw 14. The multiple push-pull rods 17 are arranged one-to-one with multiple first sliders 3, and the push-pull rods 17 are hinged to the sides of the first sliders 3. When the second knob 15 is turned, the second knob 15 drives the second screw 14 to rotate. When the movable part 16 on the second screw 14 moves downward, the multiple first sliders 3 can move synchronously away from the center of the processing table 1 through the transmission of the push-pull rods 17. When the second knob 15 is turned in the opposite direction, the multiple first sliders 3 can be driven to move in the opposite direction.
[0026] Example 4
[0027] Please see Figure 3 The adjustment component includes a bidirectional lead screw 18 rotatably mounted on the bottom surface of the processing table 1. The bidirectional lead screw 18 is driven by a servo motor 19 set on the bottom surface of the processing table 1. Screw sleeves 20 are symmetrically mounted on the two threaded parts of the bidirectional lead screw 18. The second slider 4 is fixedly mounted on the screw sleeves 20. When the bidirectional lead screw 18 rotates, the screw sleeves 20 drive the second slider 4 to move, precisely adjusting the distance between the outer grinding roller 7 and the inner grinding roller 6. This ensures that the outer grinding roller 7 fits tightly with the outer ring of the ring parts of different diameters, providing precise position adjustment for synchronous grinding of the inner and outer surfaces, and ensuring grinding accuracy and effect.
[0028] Example 5
[0029] Please see Figure 4 An extension platform 21 is fixedly provided on the side of the first slider 3 near the second slider 4. Multiple balls 22 are installed on the extension platform 21. The extension platform 21 and the balls 22 can provide support for the bottom surface of the annular part. The rolling characteristics of the balls 22 effectively reduce the rotation resistance of the part, making the part rotate more stably and smoothly during the grinding process, avoiding wear or uneven grinding of the part due to excessive friction, and further improving the grinding quality and efficiency.
[0030] Working principle:
[0031] In use, first place the annular part between the inner grinding roller 6 and the outer grinding roller 7 on the processing table 1. Turn the second knob 15, and the second screw 14 of the drive assembly will drive the movable part 16 to move downwards. Through the push-pull rod 17, multiple first sliders 3 will move synchronously towards the annular part until the inner grinding roller 6 and the inner drive roller 9 contact the inner ring of the annular part. Start the servo motor 19, and the bidirectional lead screw 18 of the adjustment assembly will rotate, driving the screw sleeve 20 and the second slider 4 to move, adjusting the distance between the outer grinding roller 7 and the outer ring of the annular part so that they fit tightly.
[0032] Subsequently, the drive motor 10 starts, driving the inner drive roller 9 to rotate. This rotation utilizes friction to rotate the annular part. Simultaneously, the grinding motor 8 drives the inner grinding roller 6 and the outer grinding roller 7 to rotate at high speed, grinding the inner and outer surfaces of the part synchronously. To further improve the rotational stability of the part, the first knob 13 can be turned, causing the first screw 12 to drive the outer drive roller 11 to contact the outer ring of the annular part, working in conjunction with the inner drive roller 9 to stabilize the part's rotation.
[0033] During the grinding process, the ball bearings 22 on the extension table 21 provide support to the bottom surface of the part, reducing rotational resistance. After grinding is completed, the second knob 15 is turned in the opposite direction, and the first slider 3 drives the inner grinding roller 6 and the inner drive roller 9 away from the part, so that the processed ring part can be removed.
[0034] This structure achieves synchronous grinding of the inner and outer surfaces of ring-shaped parts through the coordinated work of the drive component, adjustment component, and each grinding roller and drive roller. It can also be adapted to parts of different sizes, effectively solving the problems of low efficiency and poor versatility of existing technologies.
[0035] The motor involved in the embodiments, its matching control system, electromagnetic switch and pipeline circuit can also be provided by the manufacturer. In addition, the control module for controlling the operation of the motor involved in this utility model is all existing technology, which can be fully implemented by those skilled in the art, and there is no need to elaborate. The content protected by this utility model does not involve any improvement to the internal structure and method.
[0036] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
