In this application, "small waist" refers to a structure in which the diameter of the two ends of the material is larger than the diameter of the middle part of the material; that is, Figure 6 As shown, the middle portion can be an arc groove or a square groove. Further, the second grinding unit 40 mentioned below is used for grinding the groove, that is, the groove can be an arc groove or a square groove.

[0048] See also Figures 1 to 5 This embodiment provides an automatic engraving machine for processing small waist jewelry, including:

[0049] Base 10;

[0050] A clamping assembly 20, the clamping assembly 20 is placed on the base 10, and the clamping assembly 20 includes: a clamping rod 21, the clamping rod 21 rotates around its rotation center, and the material is sleeved on the clamping rod 21;

[0051] A first grinding unit 30, wherein the first grinding unit 30 is placed on the base 10, wherein a first grinding end 31 of the first grinding unit 30 rotates around its rotation axis, and the first grinding unit 30 and the clamping assembly 20 are arranged to move relative to each other; the first grinding end 31 rotates around its rotation center to form a first cylinder, and the first grinding end 31 is used to grind the surface of the material;

[0052] The second grinding unit 40 is placed on the base 10, the second grinding end 41 of the second grinding unit 40 rotates around its rotation axis, and the second grinding unit 40 and the clamping assembly 20 are arranged to move relative to each other; the second grinding end 41 rotates around its rotation center to form a second column, and the length of the second column formed by the second grinding end 41 is less than the length of the material, and the second grinding unit 40 is used to grind the material and form a groove.

[0053] The base 10 is a supporting structure of the automatic lathe, and is used to support the clamping assembly 20, the first grinding unit 30 and the second grinding unit 40 mentioned below to ensure stable operation of the grinding operation. Further, the base 10 can be made of solid materials such as cast iron or steel.

[0054] The clamping assembly 20 is placed on the base 10, and the clamping assembly 20 includes: a clamping power source and the clamping rod 21. The clamping power source is connected to the clamping rod 21, and the clamping power source is used to drive the clamping rod 21 to rotate around its own rotation center. The clamping power source can be placed directly on the base 10, and can also be placed on the base 10 through a bracket.

[0055] The clamping rod 21 can rotate around its rotation center. Specifically, during processing, the material is sleeved on the clamping rod 21, and the clamping rod 21 drives the material to rotate to grind the outer wall of the material. It should also be noted that the material is a columnar structure, and there is a through hole in the middle of the material. The clamping rod 21 is placed in the through hole, and the clamping rod 21 is adapted to the through hole.

[0056] The first grinding unit 30 is placed on the base 10 , and the first grinding unit 30 includes: a first grinding power source and the first grinding end 31 , the first grinding end 31 is connected to the first grinding power source, and the first grinding power source is used to drive the first grinding end 31 to rotate around its own rotation center.

[0057] When the first grinding end 31 rotates around its rotation axis, the first grinding end 31 forms a first cylinder, and the side wall of the first cylinder is a flat surface, so as to grind the outer wall of the material to make the outer wall of the material smooth.

[0058] During processing, the first grinding unit 30 and the clamping assembly 20 move relative to each other, so that the first grinding end 31 contacts the surface of the material, and grinds the surface of the material by rotating and moving to remove burrs and uneven parts on the surface and make the surface of the material smooth.

[0059] The second grinding unit 40 is placed on the base 10, and includes a second grinding power source and a second grinding end 41. The second grinding end 41 is connected to the second grinding power source, and the second grinding power source is used to drive the second grinding end 41 to rotate around its own rotation center.

[0060] When the second grinding end 41 rotates around its rotation axis, a second column is formed. It should be noted that the side wall of the second column can be a flat surface or an arc-shaped curved surface convex outward. Further, when the side wall of the second column is a flat surface, the length of the column formed by the second grinding end 41 is less than the length of the material. The groove formed by the second grinding end 41 can be an arc groove or a square groove, so that the diameter of the two ends of the material is greater than the diameter of the middle part of the material.

[0061] During the grinding operation, the second grinding unit 40 is also arranged to move relative to the clamping assembly 20, so that the second grinding end 41 can form a groove on the material. By adjusting the parameters and position of the second grinding unit 40, the depth, width and position of the groove can be controlled.

[0062] Furthermore, during the grinding operation, the first grinding end 31 and the second grinding end 41 may perform the grinding operation alternately or sequentially.

[0063] Different from the prior art, the above technical solution can realize rapid and continuous processing of materials by setting the clamping assembly 20 and the first polishing unit 30 to move relative to each other, and the clamping assembly 20 and the second polishing unit 40 to move relative to each other, thereby greatly improving production efficiency. At the same time, by accurately controlling the motion parameters of the clamping assembly 20, the first polishing unit 30 and the second polishing unit 40, precise processing of small waist jewelry can be achieved.

[0064] The traditional jewelry processing process often requires a lot of manual operation, which is not only inefficient but also easily affected by human factors. The automatic processing method of the automatic flower cutting machine greatly reduces the degree of manual participation, reduces labor costs, and also reduces the possibility of human errors.

[0065] According to some embodiments of the present application, referring to Figures 1 to 5 , the rotation center of the first grinding unit 30 is parallel to the rotation center of the clamping rod 21 , and / or the rotation center of the second grinding unit 40 is parallel to the rotation center of the clamping rod 21 .

[0066] In this embodiment, the rotation center of the first grinding end 31 is parallel to the rotation center of the clamping rod 21, or the rotation center of the second grinding end 41 is parallel to the rotation center of the clamping rod 21, or both are parallel. The clamping rod 21, the first grinding end 31 and the second grinding end 41 can rotate independently. After the corresponding processing parameters are preset, the material is sleeved on the clamping rod 21 and drives it to rotate, while the first grinding end 31 and the second grinding end 41 rotate and move relative to the clamping rod 21 and the material to achieve the purpose of grinding and turning.

[0067] The rotation center of the first grinding end 31 is parallel to the rotation center of the clamping rod 21, so that the first grinding end 31 grinds the surface of the material evenly, thereby avoiding the problem of uneven grinding caused by non-parallel rotation centers. Similarly, when the rotation center of the second grinding end 41 is parallel to the rotation center of the clamping rod 21, the groove formed on the material by the second grinding end 41 will also be more uniform and precise.

[0068] Of course, in some embodiments, the rotation center of the first grinding end 31 and the rotation center of the clamping rod 21 have an angle, that is, the first column grinds the material with its edge, specifically, the first grinding end 31 is driven to rotate, and the clamping assembly 20 and the first grinding unit 30 are driven to move relative to each other to grind the outer surface of the material. The second grinding end 41 is similar.

[0069] According to some embodiments of the present application, referring to Figures 1 to 5 , further comprising: a third grinding unit 50, the third grinding unit 50 being placed on the base 10, the third grinding end 51 of the third grinding unit 50 rotating around its rotation axis, the third grinding unit 50 being arranged to move relative to the clamping assembly 20;

[0070] The third grinding end 51 rotates around its rotation center to form a cone. Further, the rotation center of the third grinding end 51 is perpendicular to the rotation center of the clamping rod 21.

[0071] The third grinding unit 50 is placed on the base 10, and the rotation center of the third grinding end 51 of the third grinding unit 50 is perpendicular to the rotation center of the clamping rod 21. The third grinding unit 50 includes a third grinding power source and the third grinding end 51. The third grinding end 51 is connected to the third grinding power source, and the third grinding power source is used to drive the third grinding end 51 to rotate around its own rotation center.

[0072] When the third grinding end 51 rotates around its rotation axis, a cone is formed, and the top of the cone is disposed toward the material.

[0073] When the automatic engraving machine starts working, the clamping rod 21 of the clamping assembly 20 starts to rotate, driving the material mounted thereon to rotate; it should be noted that when the third polishing unit 50 is operating, the clamping assembly 20 drives the material to rotate, which means that it stops rotating after rotating a certain angle, waiting for the third polishing unit 50 to polish and carve. The tip of the cone shape contacts the outer surface of the material, and performs fine carving or modification to add unique textures or patterns.

[0074] According to some embodiments of the present application, referring to Figures 1 to 5 , further comprising: a displacement component 60;

[0075] The displacement assembly 60 is placed on the base 10 , and the first grinding unit 30 , the second grinding unit 40 and the third grinding unit 50 are all placed on the displacement assembly 60 , and the displacement assembly 60 is used to drive the first grinding unit 30 , the second grinding unit 40 and the third grinding unit 50 to move.

[0076] The displacement assembly 60 includes: a first horizontal translation unit 61, a second horizontal translation unit 62, a first vertical translation unit 63 and a second vertical translation unit 64;

[0078] The fixed ends of the first vertical translation unit 63 and the second vertical translation unit 64 are both placed on the movable end of the second horizontal unit, the second grinding unit 40 is placed on the movable end of the first vertical translation unit 63 , and the third grinding unit 50 is placed on the movable end of the second vertical translation unit 64 .

[0079] The first horizontal translation unit 61, the second horizontal translation unit 62, the first vertical translation unit 63 and the second vertical translation unit 64 have similar structures. The first horizontal translation unit 61 is taken as an example below, and the other translation units are not described in detail. It is further explained that the difference between horizontal and vertical is only the difference in the direction of movement. Horizontal translation refers to translation in the horizontal direction, and vertical refers to translation in the vertical direction.

[0080] The first horizontal translation unit 61 includes: a fixed end, a mobile end, a slide rail and a mobile power source; the slide rail is placed on the fixed end, the mobile end is adapted to the slide rail, and the mobile end is slidably arranged on the slide rail, the mobile power source is transmission-connected to the mobile end, and the mobile power source is used to drive the mobile end to slide on the slide rail.

[0081] It is also necessary to further explain that the fixed end of the first horizontal translation unit 61 is mounted on the base 10, and the first horizontal translation unit 61 is used to control the horizontal movement of the second horizontal translation unit 62. The fixed end of the second horizontal movement unit is mounted on the moving end of the first horizontal movement unit, and the first grinding unit 30 is placed on the fixed end of the second horizontal movement unit, that is, the first grinding unit 30 moves together with the second horizontal movement unit.

[0082] The first vertical translation unit 63 and the second vertical translation unit 64 are disposed on the moving end of the second horizontal translation unit 62. The second grinding unit 40 is disposed on the moving end of the first vertical translation unit 63, and the third grinding unit 50 is disposed on the moving end of the second vertical translation unit 64. By controlling the two vertical translation units, the second grinding unit 40 and the third grinding unit 50 can be precisely moved to a desired position in the vertical direction.

[0083] During operation, the clamping rod 21 of the clamping assembly 20 drives the material to rotate. At the same time, the displacement assembly 60 drives the first grinding unit 30, the second grinding unit 40 and the third grinding unit 50 to move and position accurately by controlling the movement of each translation unit according to a preset processing path or real-time processing requirements.

[0084] The first grinding unit 30 is mainly used for preliminary grinding and smoothing of the surface of the material. The second grinding unit 40 forms a specific groove or shape on the material. The third grinding unit 50 is used for fine carving or shaping of the material.

[0085] According to some embodiments of the present application, referring to Figure 6 , further comprising: a wiping unit 80, wherein the wiping unit 80 is disposed below the clamping rod 21, and the wiping unit 80 and the clamping rod 21 are arranged to move relative to each other, and the wiping unit 80 is used to wipe the material.

[0086] The wiping unit 80 is disposed below the clamping rod 21 , and is used to wipe the surface of the material and cool the material when the material is rotated by the clamping rod 21 .

[0087] The wiping unit 80 is a wiping cloth, a sponge or other soft wiping materials, which can effectively remove impurities, dust or residues generated during the grinding process on the surface of the material, and at the same time, can also cool the material, that is, water is mixed in the wiping unit 80.

[0088] During the operation, the material is first placed on the clamping rod 21 and driven to rotate by the clamping rod 21. After the material is polished or during the polishing process, the clamping assembly 20 and the wiping unit 80 move relative to each other, and the wiping unit 80 contacts the surface of the material and wipes it. The wiping unit 80 can effectively remove impurities and residues on the surface of the material, ensure the cleanliness of the surface of the material, and improve the quality of the jewelry.

[0089] By setting the wiping unit 80, the material can be automatically wiped after or during processing, thereby improving production efficiency and product quality.

[0091] The material chamber 72 is a hollow cavity for accommodating materials to be processed. A discharge hole is provided on the side wall of the material bin 71, and the discharge hole is connected to the material chamber 72, so that the material can be discharged from the material chamber 72 through the discharge hole. Specifically, when loading, the clamping rod 21 passes through the discharge hole and through the through hole in the material to clamp the material. The loading unit 70 and the clamping assembly 20 are arranged to move relative to each other so that the clamping rod 21 clamps the material; further, the cross-section of the material chamber 72 is adapted to the material, and when the bottom material is clamped, the material can fall automatically.

[0092] During operation, the material to be processed is first placed in the material cavity 72 of the material bin 71. When the automatic lathe is ready to start processing, the loading unit 70 starts to work. The loading unit 70 and the clamping assembly 20 move relative to each other so that the discharge hole of the material bin 71 is aligned with the clamping rod 21. At this time, the holding rod passes through the discharge hole and the through hole in the material in turn, and the material moves downward under the action of gravity or other auxiliary force (spring).

[0093] According to some embodiments of the present application, a material unloading unit; the material unloading unit comprises: a first clamping portion and a second clamping portion, the first clamping portion and the second clamping portion are arranged to move relative to each other, and are used to clamp the material sleeved on the clamping rod 21;

[0094] The unloading unit and the clamping assembly 20 are arranged to move relative to each other.

[0095] The material discharging unit comprises a first clamping part and a second clamping part. The two clamping parts can move relative to each other so as to clamp the material sleeved on the clamping rod 21, and then the material discharging unit and the clamping assembly 20 move relative to each other so that the material is separated from the clamping rod.

[0096] Further, after the grinding is completed, the clamping rod 21 and the material discharging unit move relative to each other, and then the first clamping part and the second clamping part move relative to each other and clamp the material. After the material is clamped, the material discharging unit and the clamping assembly 20 start to move relative to each other, so that the material is separated from the clamping rod 21.
