Description

Technical Field

[0001] This utility model relates to a transmission device for a stone grinding head, specifically a transmission device that is highly efficient and durable. Background Technology

[0002] It is understood that stone can be used as a raw material for various buildings or furniture. Before being used as a raw material for buildings or furniture, the surface of the stone is usually polished to make the surface of the stone fine and smooth, so as to show the unique texture of the stone.

[0003] For example, a stone slab grinding head disclosed in Taiwan Patent Publication No. 321035 mainly uses its guide rail and arc protrusion to control the sliding of the pendulum, so that the whetstone seat swings to grind the stone surface, thereby improving grinding efficiency. However, because the operation method is sliding control, the guide rail, arc protrusion and its corresponding sliding components will continuously rub against each other during operation, causing wear. When the wear reaches a certain level, it will affect the precision and accuracy of grinding, making the grinding depth inconsistent and causing defective products.

[0004] Therefore, how to provide a transmission device or structure that can make the stone grinding head operate stably and not easily wear out is the direction that the inventors of this case are eager to study and improve.

[0005] Therefore, in view of the above-mentioned deficiencies, the inventor collected relevant information, conducted multiple evaluations and considerations, and, based on years of experience accumulated in this industry, designed this utility model patent through continuous trial and modification. Utility Model Content

[0006] The main objective of this invention is to provide a transmission device for a stone grinding head, comprising at least a housing, multiple gear shafts, an internal gear disc, a turntable, and an eccentric wheel. The housing is axially mounted on a drive shaft, and multiple mounting seats are provided around the outer periphery of the housing. The gear shafts are respectively mounted in each mounting seat, and each gear shaft can be connected to a swing foot. The internal gear disc is locked inside the housing, and the turntable is fitted inside the internal gear disc. The outer teeth of the turntable can mesh with the internal gear disc, and multiple racks at the bottom of the turntable can mesh with each gear shaft. The eccentric wheel is nested inside the turntable and can be connected and controlled by the drive shaft. When the eccentric wheel drives the turntable to rotate eccentrically on the internal gear disc, the racks of the turntable and the gear shafts reciprocate radially, causing the gear shafts to reciprocate and deflect, thus causing the swing feet to swing. Through these meshing, transmission is achieved, achieving both high efficiency and high durability.

[0007] To achieve the above objective, the number of teeth in the internal gear plate is the same as the number of teeth in the external gear plate of the turntable, so that when the turntable rotates eccentrically, each rack portion of the turntable can accurately reciprocate radially at each gear shaft, thereby controlling the reciprocating deflection of each gear shaft.

[0008] As a further improvement of this utility model, the deflection angle of each gear shaft is set to ±8 degrees to ±13 degrees.

[0009] As a further improvement of this utility model, the eccentricity of the eccentric wheel is set to 3-9 mm.

[0010] As a further improvement of this utility model, the eccentricity of the eccentric wheel is set to 6mm. Attached Figure Description

[0030] To achieve the above or other objectives and effects, the technical means and structure adopted by this utility model are described in detail below with reference to the preferred embodiment of this utility model, so as to facilitate a complete understanding.

[0031] Please see Figures 1 to 8 The figures show a structural schematic diagram and a preferred embodiment of the present invention. As shown in these figures, the present invention mainly provides a transmission device for a stone grinding head, comprising at least:

[0032] A housing 10 is axially sleeved on a drive shaft, and a plurality of mounting seats 11 are provided around the outer periphery of the housing 10;

[0033] Multiple gear shafts 20 are respectively mounted in each mounting base 11 of the housing 10, and each gear shaft 20 can be connected to a swing foot A.

[0034] An internal gear disk 30 is locked inside the housing 10, and an internal tooth portion 31 is provided around the inner circumference of the internal gear disk.

[0035] A turntable 40 is fitted inside the internal gear disk 30. The turntable 40 has at least one external toothed portion 41 and a plurality of rack portions 42. The external toothed portion 41 is arranged around the outer periphery of the turntable 40 and can mesh with the internal toothed portion 31 of the internal gear disk 30. The plurality of rack portions 42 are located at the bottom of the turntable 40 and can mesh with each gear shaft 20.

[0036] An eccentric wheel 50 is nested inside the turntable 40 and can be connected and controlled by the drive shaft. When the eccentric wheel 50 drives the turntable 40 to rotate eccentrically on the internal gear plate 30, the rack portions 42 of the turntable 40 and the gear shafts 20 reciprocate radially, causing the gear shafts 20 to reciprocate and deflect.

[0037] The number of teeth in the inner toothed portion 31 of the inner toothed disk 30 is the same as the number of teeth in the outer toothed portion 41 of the turntable 40.

[0038] The deflection angle of each gear shaft 20 is set to ±8 degrees to ±13 degrees.

[0039] The eccentricity of the eccentric wheel 50 is set to 3-9 mm.

[0040] The eccentricity of the eccentric wheel 50 is set to 6mm;

[0041] This utility model is mainly installed in a stone grinding machine (not shown in the figure). During use, the drive shaft provides power, and the utility model controls the reciprocating oscillation of each swing foot A to grind the stone surface. More specifically, while the drive shaft of the stone grinding machine drives the eccentric wheel 50 to rotate, the eccentric wheel 50 drives the turntable 40 to rotate eccentrically within the internal gear disc 30. Preferably, a bearing sleeve can be provided between the eccentric wheel 50 and the turntable 40, allowing the eccentric wheel 50 to smoothly drive the turntable 40. Because the outer teeth 41 of the turntable 40 and the internal gear disc 30... The internal teeth 31 mesh with each other, so that when the turntable 40 rotates eccentrically, each rack portion 42 of the turntable 40 reciprocates radially relative to its original position, causing each gear shaft 20 meshing with each rack portion 42 to reciprocate and deflect, thereby driving each swing foot A connected to each gear shaft 20 to reciprocate and grind the stone surface. The meshing of each rack portion 42 of the turntable 40 with each gear shaft 20 provides transmission, giving this utility model good transmission efficiency and reducing wear between parts, achieving the goal of both high efficiency and high durability.

[0042] As described above, in the preferred embodiment of this utility model, the number of teeth of the inner toothed portion 31 of the inner toothed disk 30 is the same as the number of teeth of the outer toothed portion 41 of the turntable 40, so that when the turntable 40 rotates eccentrically, each rack portion 42 of the turntable 40 can accurately reciprocate radially at each gear shaft 20, and reliably control each gear shaft 20 to reciprocate deflection and make each swing foot A swing back and forth.

[0043] In addition, in a preferred embodiment of this invention, the user can adjust the number of gear shafts 20 to configure a corresponding number of swing feet A (e.g., ...). Figure 1 As shown), for example, it is configured with 8 swing feet A or 6 swing feet A (as shown). Figures 7 to 8 As shown in the figure, the number of swing feet A configured in this utility model is not limited, as is stated here.

[0044] In addition, in a preferred embodiment of the present invention, the deflection angle of each gear shaft 20 is set to ±8 degrees to ±13 degrees, so that the reciprocating swing of each swing foot A can reach ±13 degrees, so that the present invention can provide good cutting and grinding capabilities for each swing foot A while operating efficiently.

[0045] In addition, in a preferred embodiment of the present invention, the eccentricity of the eccentric wheel 50 is set to 3-9 mm, and in the best embodiment of the present invention, the eccentricity of the eccentric wheel 50 is set to 6 mm. The eccentricity of the eccentric wheel 50 is used to accurately control the eccentric rotation of the turntable 40. The outer tooth 41 of the turntable 40 meshes with the inner tooth 31 of the inner tooth disk 30, so that each rack portion 42 of the turntable 40 can accurately reciprocate radial displacement, thereby achieving the purpose of accurately controlling the deflection of each gear shaft 20 and the swaying of each swing foot A.

[0046] In summary, compared to the problems existing in the conventional transmission method of stone grinding heads, this utility model, through the special combination design of the housing 10, gear shaft 20, internal gear disk 30, turntable 40 and eccentric wheel, drives the turntable 40 to rotate eccentrically within the internal gear disk 30 via the eccentric wheel 50. The external teeth 41 of the turntable 40 mesh with the internal teeth 31 of the internal gear disk 30, causing the racks 42 of the turntable 40 to reciprocate radially in their original positions during eccentric rotation. Since each rack 42 meshes with each gear shaft 20, each rack 42 can drive each gear shaft 20 to reciprocate, thereby driving each swing foot A connected to each gear shaft 20 to swing back and forth, achieving both high efficiency and high durability.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the patent scope of the present utility model. Therefore, any simple modifications and equivalent structural changes made based on the description and drawings of the present utility model should also be included within the patent scope of the present utility model and are hereby stated.
