Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a workpiece movement mechanism based on a grinder. Background Art

[0002] After many metal workpieces (such as metal plates with a cuboid structure) are machined mechanically, the surface roughness cannot meet the requirements. Therefore, subsequent grinding operations need to be carried out on their surfaces so that the surfaces of the workpieces meet the usage requirements. At present, the movement mode of the workpiece in the grinder is relatively single. Usually, the workpiece is clamped and positioned and then reciprocates along one direction (X direction) for grinding, and then reciprocates along another direction (Y direction) for grinding. The single reciprocating movement mode of the workpiece easily leads to poor surface grinding uniformity and low grinding efficiency. Summary of the Utility Model

[0007] Preferably, an outer support ring for supporting the planetary gear discs is arranged on the lower side of the gear ring, and an inner support ring for supporting the planetary gear discs is arranged on the lower side of the gear. The top surface of the outer support ring and the top surface of the inner support ring are coplanar, and the top surface of the outer support ring is higher than the upper surface of the grinding disc, so that a gap is formed between the surface of the planetary gear discs and the surface of the grinding disc.

[0008] Preferably, a connecting seat is arranged on the lower side of the grinding base. A protective groove for preventing the grinding fluid from splashing out is arranged on the connecting seat. The grinding base is arranged in the protective groove, and an annular liquid storage groove is formed between the grinding base and the protective groove.

[0009] Preferably, the bottom of the protective groove is fixedly connected to the mounting base through a connecting column. The power is configured as a motor, which is installed on the connecting seat. A transmission shaft is provided on the gear. A bearing seat is provided at the center of the bottom of the grinding base. The transmission shaft passes through the bearing seat and is connected to the motor shaft through a coupling.

[0010] Preferably, an avoidance through-hole is provided at the center of the grinding disc, and a plurality of drainage micro-grooves for guiding the grinding fluid are provided on the grinding surface of the grinding disc and are radially distributed along the circumferential direction.

[0021] It should be understood that in this text, expressions such as "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance, nor should they be construed as implicitly specifying the quantity of the indicated technical features. Features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0022] As Figure 1 and Figure 6 A workpiece motion mechanism based on a grinding machine as shown includes a grinding base 10 for storing grinding fluid. A grinding disc 11 is fixedly provided at the bottom of the grinding base 10. A gear ring 12 is provided around the grinding base, a gear 13 is provided at the center of the grinding base 10, and a power source 14 for driving the gear to rotate is provided at the bottom of the grinding base; a number of planetary gear discs 15 are provided between the gear 13 and the gear ring 12. A number of limiting through slots 150 for installing a workpiece 16 are provided on the planetary gear discs 15. The thickness of the planetary gear discs 15 is less than the thickness of the workpiece to be ground; when the workpiece is loaded into the limiting through slot, under the action of gravity, the lower surface of the workpiece abuts against the upper surface of the grinding disc.

[0023] An outer support ring 120 for supporting the planetary gear discs is provided on the lower side of the gear ring 12, and an inner support ring 130 for supporting the planetary gear discs is provided on the lower side of the gear 13. The top surface of the outer support ring is coplanar with the top surface of the inner support ring, and the top surface of the outer support ring is higher than the upper surface of the grinding disc, so that a gap is formed between the surface of the planetary gear disc and the surface of the grinding disc. When the planetary gear disc rotates, there is no friction with the grinding disc, and only friction occurs between the workpiece and the grinding disc. On the one hand, the transmission resistance is reduced, and on the other hand, the service life of the planetary gear disc is increased.

[0024] A connecting seat 20 is provided on the lower side of the grinding base 10. A protective groove 21 for preventing grinding fluid from splashing is provided on the connecting seat 20. The grinding base is arranged in the protective groove, and an annular liquid storage groove 210 is formed between the grinding base and the protective groove. The bottom of the protective groove 21 is fixedly connected to the connecting seat through a connecting column 211. The power source 14 is configured as a motor, and the motor is installed on the connecting seat 20. A transmission shaft 22 is provided on the gear 12, and a bearing seat 100 is provided at the center of the bottom of the grinding base 10. The transmission shaft 22 passes through the bearing seat and is connected to the motor shaft through a coupling 23.

[0025] As Figure 6 shown, an avoidance through hole 110 is provided at the center of the grinding disc 11. A number of drainage micro-grooves 111 for guiding grinding fluid are provided on the grinding surface of the grinding disc in a radially distributed manner along the circumferential direction. A number of annular micro-grooves 112 that are concentrically distributed and penetrate the drainage micro-grooves are provided on the grinding surface of the grinding disc.

[0026] Combined with the attached drawings, the principle of the present utility model is as follows: The workpiece 15 is installed in the limiting through slot 150 of the planetary gear disc 15. As Figure 1As shown, four planetary gear discs are provided, and four limiting through grooves are provided on each planetary gear disc, that is, sixteen workpieces can be ground simultaneously at one time; during grinding, grinding fluid (grinding slurry) is injected into the grinding disc, and the upper side of the workpiece is pressed by another grinding disc (not shown in the figure). The drive shaft 22 and the gear 12 are driven to rotate by the power 14, and the gear drives the planetary gear disc to rotate. The planetary gear disc rotates around the sun and rotates on its own axis at the same time, so that each workpiece rotates around the sun and rotates on its own axis synchronously. The surface of the workpiece interacts with the grinding fluid from various different directions and is ground, and the surface of the workpiece is ground and leveled evenly by the grinding fluid and the grinding disc, thereby effectively improving the grinding quality.

[0027] In the description of the present invention, it should be understood that the directions or positional relationships indicated by up and down, left and right, inner end, outer end, one end, the other end, etc. are the azimuth or positional relationships based on the azimuth or positional relationship shown in the drawings. It is only for the convenience of more clearly describing the technical solution of the present invention, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific azimuth, and should not be construed as a limitation to the present invention.

[0028] Although specific embodiments of the present invention have been described in detail here, they are given only for the purpose of explanation and should not be considered as limiting the scope of the present invention. Various substitutions, changes and modifications can be conceived without departing from the spirit and scope of the present invention.
