Description

Vibration table for surface adaptive high-precision grinding of precision metal workpieces Technical Field

[0001] This utility model belongs to the field of precision metal workpiece grinding technology, and specifically relates to a surface adaptive high-precision grinding device for precision metal workpieces used in vibration tables. Background Technology

[0002] A vibration table simulates the various environments a product encounters during manufacturing, assembly, transportation, and use. It is used to determine whether a product can withstand environmental vibrations. It is applicable to research, development, quality control, and manufacturing in various industries such as electronics, electromechanical, optoelectronics, automobiles, and toys. Vibration tables inevitably require metal parts, which need to be ground during assembly to ensure that the workpiece surface is smooth and burr-free before it can be used.

[0003] Chinese patent CN201922253106.3 discloses a dust collection device, including: a support base for supporting a hat; the support base has a hemispherical support body, a seat body located on the lower side of the support body, and a support brimming extending radially outward along the upper part of the seat body, the support body for supporting the hat body, and the support brimming for supporting the hat brim; the upper surface of the support brimming is an arc-shaped surface that is high in the middle and low on both sides.

[0004] Existing grinding devices typically fix the grinding wheel or grinding disc in one position, allowing grinding only one area of ​​the part. However, metal parts generally have surfaces, so fixing the grinding wheel in one position makes it impossible to grind the surface from all angles. The operator has to pick up the workpiece and grind it in a targeted manner, which is not conducive to the safety of the operator and affects the grinding efficiency.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0006] In response to the problems in related technologies, this utility model proposes a surface adaptive high-precision grinding device for precision metal workpieces used in vibration tables, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a surface adaptive high-precision grinding device for precision metal workpieces used in vibration tables. It includes a base, on which a driving assembly, a limiting assembly, and a grinding assembly are respectively mounted. A support frame is connected to the top of the base, and a third electric hydraulic cylinder is connected to one side of the support frame. The power output end of the third electric hydraulic cylinder is poweredly connected to a fixed frame.

The transmission belt is connected to the first transmission wheel, and the second transmission wheel is connected to the transmission belt. An adapter block is connected to the surface of the second transmission wheel, and one end of the adapter block is connected to the grinding wheel.

[0009] Furthermore, the drive assembly includes two first electric hydraulic cylinders, a first drive motor, and a support rod. The two first electric hydraulic cylinders are both located at the top of the base, and the power output ends of the two first electric hydraulic cylinders are poweredly connected to a fixed platform. The first drive motor is located at the top of the fixed platform, and the power output end of the first drive motor is poweredly connected to a half gear. The support rod is rotatably located at the top of the fixed platform, and the top of the support rod is connected to a transmission gear. The transmission gear meshes with the half gear, and the top of the transmission gear is connected to a connecting rod.

[0010] Furthermore, the limiting component includes a worktable and two second electric hydraulic cylinders.

Both second electric hydraulic cylinders are located at the top of the worktable, and the power output ends of both second electric hydraulic cylinders are poweredly connected to the limiting plate.

The grinding wheel facilitates the grinding of the workpiece surface. Two second electric hydraulic cylinders facilitate the approach of the limiting plates to clamp and limit the workpiece. The first electric hydraulic cylinder facilitates the lifting and lowering of the worktable so that the workpiece surface is in contact with the grinding wheel. The first drive motor facilitates the rotation of the half gear and transmission gear. The shape characteristics of the half gear facilitate the intermittent rotation of the worktable, silicone pad, and workpiece. This allows the grinding wheel to grind the workpiece surface linearly, and after finishing, rotate to adjust the workpiece position so that the grinding wheel can continue to grind the workpiece surface linearly.

Detailed Implementation

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please refer to Figures 1-7. This utility model is a surface adaptive high-precision grinding device for precision metal workpieces used in vibration tables. It includes a base 1, on which a driving component 2, a limiting component 3, and a grinding component 9 are respectively provided. A support frame 4 is connected to the top of the base 1. A third electric hydraulic cylinder 6 is connected to one side of the support frame 4. The power output end of the third electric hydraulic cylinder 6 is poweredly connected to a fixed frame 7. The grinding component 9 includes a second drive motor 901, a transmission belt 903, a second transmission wheel 904, and a grinding wheel 906. The second drive motor 901 is located on the back of the fixed frame 7. The power output end of the second drive motor 901 is poweredly connected to a first transmission wheel 902. The transmission belt 903 is connected to the first transmission wheel 902. The second transmission wheel 904 is connected to the transmission belt 903. An adapter block 905 is connected to the surface of the second transmission wheel 904. One end of the adapter block 905 is connected to the grinding wheel 906.

[0031] First, the workpiece is placed on the limiting component 3, which limits its movement. Then, the driving component 2 drives the limiting component 3 to rise, bringing the workpiece surface into contact with the grinding wheel 906. The second driving motor 901 then drives the first transmission wheel 902, the transmission belt 903, and the second transmission wheel 904 to rotate, which in turn drives the adapter block 905 and the grinding wheel 906 to rotate. The grinding wheel 906 can then grind the surface of the workpiece. During the grinding process, the third electric hydraulic cylinder 6 drives the grinding wheel 906 to move horizontally in a straight line to grind the surface of the workpiece in a straight line. When it is necessary to switch the grinding position, the driving component 2 drives the workpiece to rotate intermittently, which adjusts the rotation position of the workpiece each time, so that the grinding wheel 906 grinds the surface of the workpiece in a straight line again until the top surface of the workpiece is fully ground after one rotation, thus improving the grinding accuracy.

[0032] The second drive motor 901 facilitates the rotation of the first transmission wheel 902, transmission belt 903, second transmission wheel 904, adapter block 905, and grinding wheel 906. The grinding wheel 906 facilitates the grinding of the workpiece surface. The drive assembly 2 can drive the limit assembly 3 to rise and fall while also driving the workpiece on the limit assembly 3 to rotate intermittently. This allows the grinding wheel 906 to perform one horizontal grinding operation on the workpiece surface in a straight line, and then rotate to adjust the position of the workpiece so that the grinding wheel 906 can continue to perform linear grinding on the workpiece surface. This reciprocating linear motion facilitates comprehensive grinding of the surface and improves the grinding accuracy.

[0033] In one embodiment, the drive assembly 2 includes two first electric hydraulic cylinders 21, a first drive motor 23, and a support rod 25. The two first electric hydraulic cylinders 21 are both disposed at the top of the base 1. The power output ends of the two first electric hydraulic cylinders 21 are poweredly connected to a fixed platform 22. The first drive motor 23 is disposed at the top of the fixed platform 22. The power output end of the first drive motor 23 is poweredly connected to a half gear 24. The support rod 25 is rotatably disposed at the top of the fixed platform 22. The top of the support rod 25 is connected to a transmission gear 26, which meshes with the half gear 24. The top of the transmission gear 26 is connected to a connecting rod 27.

[0034] First, the workpiece is placed on the limiting component 3, which then limits its movement. Next, two first electric hydraulic cylinders 21 operate, causing the fixed platform 22 and the limiting component 3 to rise, bringing the workpiece surface into contact with the grinding wheel 906. Then, the second drive motor 901 drives the first transmission wheel 902, transmission belt 903, and second transmission wheel 904 to rotate, which in turn drives the adapter block 905 and the grinding wheel 906 to rotate. The grinding wheel 906 then polishes the workpiece surface. During polishing, the third electric hydraulic cylinder 6 drives the grinding wheel 906 horizontally. The linear movement is used to perform linear grinding on the surface of the workpiece. When it is necessary to change the grinding position, the first drive motor 23 drives the half gear 24 to rotate. Then, the shape characteristics of the half gear 24 drive the transmission gear 26 to rotate intermittently. At this time, the workpiece is rotated intermittently, which can adjust the rotation position of the workpiece each time. Then, during each intermittent rotation, the third electric hydraulic cylinder 6 drives the grinding wheel 906 to move horizontally again to perform linear grinding on the surface of the workpiece. That is, grinding is performed once after each rotation and position change, until the workpiece rotates one revolution and completes the full grinding of the top surface of the workpiece, thus improving the grinding accuracy.

[0035] The second drive motor 901 facilitates the rotation of the first transmission wheel 902, transmission belt 903, second transmission wheel 904, adapter block 905, and grinding wheel 906. The grinding wheel 906 facilitates the grinding of the workpiece surface. The first electric hydraulic cylinder 21 facilitates the lifting and lowering of the limiting component 3 so that the workpiece surface is in contact with the grinding wheel 906. The first drive motor 23 facilitates the rotation of the half gear 24 and transmission gear 26. The shape characteristics of the half gear 24 facilitate the intermittent rotation of the workpiece on the limiting component 3. After the grinding wheel 906 finishes grinding the workpiece surface in a straight line, it rotates to adjust the position of the workpiece so that the grinding wheel 906 can continue to grind the workpiece surface in a straight line. This reciprocating linear motion facilitates comprehensive grinding of the surface and improves the grinding accuracy.

[0036] In one embodiment, the limiting component 3 includes a worktable 31 and two second electric hydraulic cylinders 33. The worktable 31 is disposed at the top of the connecting rod 27, and a silicone pad 32 is connected to the top of the worktable 31. Both second electric hydraulic cylinders 33 are disposed at the top of the worktable 31, and the power output ends of both second electric hydraulic cylinders 33 are poweredly connected to limiting plates 34, thereby facilitating the clamping and limiting of the workpiece from both sides through the two limiting plates 34.

[0037] In one embodiment, for the aforementioned limiting plates 34, the bottom ends of both limiting plates 34 are slidably attached to the top end of the worktable 31, thereby facilitating the provision of support for the movement of the limiting plates 34 and thus improving the stability of the movement of the limiting plates 34.

[0038] In one embodiment, the silicone pad 32 has a workpiece placed on its top end, and one side of each of the two limiting plates 34 is in contact with the surface of the workpiece, which facilitates clamping and limiting the workpiece to prevent displacement of the workpiece during grinding.

[0039] In one embodiment, for the support frame 4, the bottom end of the support frame 4 is connected to two slide rails 5, and the top end of the fixed frame 7 is connected to four sliders 8. The inner sides of each pair of sliders 8 are slidably connected to the surface of each slide rail 5, which helps to avoid the load-bearing situation of the third electric hydraulic cylinder 6 and improves the stability of the overall movement of the fixed frame 7 and the grinding wheel 906 driven by the third electric hydraulic cylinder 6.

[0040] In one embodiment, the surface of the adapter block 905 is rotatably connected to the inner side of the fixing frame 7, which facilitates the provision of support force for the adapter block 905 and thereby improves the stability of the adapter block 905 driving the grinding wheel 906 to rotate.

[0041] In summary, using the above-mentioned technical solution of this utility model, the workpiece is first placed on the silicone pad 32 on the surface of the worktable 31. The friction of the silicone pad 32 provides initial positioning for the workpiece. Then, the two second electric hydraulic cylinders 33 operate, causing the two limiting plates 34 to approach each other, thereby clamping and limiting the workpiece. The two first electric hydraulic cylinders 21 operate, causing the fixed table 22 and the worktable 31 to rise as a whole, so that the surface of the workpiece comes into contact with the grinding wheel 906. Then, the second drive motor 901 drives the first transmission wheel 902, the transmission belt 903, and the second transmission wheel 904 to rotate, thereby driving the adapter block 905 and the grinding wheel 906 to rotate. Thus, the workpiece can be ground by the grinding wheel 906. The surface of the workpiece is polished. During the polishing process, the third electric hydraulic cylinder 6 drives the polishing wheel 906 to move horizontally in a straight line to polish the surface of the workpiece in a straight line. When it is necessary to change the polishing position, the first drive motor 23 drives the half gear 24 to rotate. Then, the shape characteristics of the half gear 24 drive the transmission gear 26 to rotate intermittently. At this time, the workpiece is rotated intermittently, so the rotation position of the workpiece can be adjusted each time. Then, during each intermittent rotation, the third electric hydraulic cylinder 6 will drive the polishing wheel 906 to move horizontally again to polish the surface of the workpiece in a straight line. That is, after each rotation and position change, polishing is performed once until the workpiece rotates one revolution and the top surface of the workpiece is fully polished, thus improving the polishing accuracy.

[0042] Through the above technical solution, the second drive motor 901 facilitates the rotation of the first transmission wheel 902, transmission belt 903, second transmission wheel 904, adapter block 905, and grinding wheel 906. The grinding wheel 906 facilitates the grinding of the workpiece surface. The two second electric hydraulic cylinders 33 facilitate the approach of the limiting plate 34 to clamp and limit the workpiece. The first electric hydraulic cylinder 21 facilitates the lifting and lowering of the worktable 31 so that the surface of the workpiece is in contact with the grinding wheel 906. The first drive motor 23 facilitates the rotation of the half gear 24 and the transmission gear 26. The shape characteristics of the half gear 24 facilitate the intermittent rotation of the worktable 31, silicone pad 32, and workpiece. This allows the grinding wheel 906 to grind the workpiece surface linearly and then rotate to adjust the position of the workpiece so that the grinding wheel 906 can continue to grind the workpiece surface linearly. This reciprocating linear motion facilitates comprehensive grinding of the surface and improves the grinding accuracy.
