Description
Technical Field
[0001] The present application relates to the technical field of water drill production, and in particular to a swivel assembly for water drill grinding and polishing. Background Art
[0002] Rhinestones are also known as crystal diamonds and rhinestones. The main component of rhinestones is crystal glass, which is a kind of jewelry accessory obtained by cutting artificial crystal glass into diamond facets. This material is very popular because it is relatively economical and has a dazzling diamond-like visual effect. It is widely used in low- and medium-end jewelry design, so rhinestones are mainly processed in batches.
[0003] In the fully automatic production process of rhinestones, the processing of rhinestones needs to go through the processes of powder gluing, drilling, grinding, polishing, and cutting. The grinding and polishing processes of rhinestones require the use of a continuously rotating swivel assembly to process the surface of the rhinestones, so as to achieve grinding and polishing of the surface of the rhinestones and shape the rhinestone facets. At this time, the balance of the rotation of the swivel assembly is particularly important. When the swivel assembly has circular runout during the rotation process, it will cause the rhinestone facets to be over-cut, over-polished, or falsely cut, cut and polished, resulting in uneven facets of the rhinestones, affecting the performance of the rhinestones.
[0004] In the prior art, the rotational balancing process of the swivel assembly is mostly carried out by test bench testing, and then ribs are welded according to the test results to achieve the rotational balance of the swivel assembly. According to the technical solution of the prior art, there are the following problems. In the actual operation process, it is necessary to cut and open holes in the swivel assembly, and then insert ribs for welding. On the one hand, there are problems of cumbersome processing, time-consuming and labor-intensive; on the other hand, there are problems that the ribs cannot be adjusted after welding, and the flexibility is poor and cannot be changed at will. In addition, during the continuous use of the swivel assembly, due to changes in performance parameters such as mechanical deformation, the rotational balance is often easily destroyed, and the swivel assembly needs to be readjusted. At this time, the swivel assembly needs to be removed from the production line and reprocessed, resulting in production stagnation. Therefore, the prior art has technical problems such as the difficulty of the rotational balancing process of the swivel assembly and high processing costs. Utility Model Content

[0006] The present application provides a swivel assembly for water drill grinding and polishing, comprising: a cylinder shell, a cover plate, a balance support plate and a counterweight block; the balance support plate is arranged inside the cylinder shell and is parallel to the end face of the cylinder shell; the cover plate comprises a plate body and a rotating shaft, the outer periphery of the plate body is adapted to the inner wall of the cylinder shell, and is fixedly connected to the two ends of the cylinder shell, and the rotating shaft is concentric with the plate body and protrudes outward; the plate body takes its center of the circle as a reference, is evenly distributed in a ring shape, and is provided with a plurality of counterweight grooves; the counterweight block is combined with the counterweight groove to achieve counterweighting.
[0007] Specifically, one of the concepts of the present application is to improve the balance of the entire swivel structure itself through the structural design of the cylinder shell, the cover plate, and the balance support plate, to facilitate the adjustment of the swivel assembly through the counterweight block, and to improve the flexibility and simplicity of the rotational balance adjustment of the swivel assembly.

[0010] Furthermore, the counterweight groove includes a first annular groove and a second annular groove, and the second annular groove is located in the first annular groove.
[0011] Specifically, another concept of the present application is to provide a rotationally balanced adjustment groove under different torque conditions by setting a plurality of layers of annular grooves.
[0012] Furthermore, the radius of the second annular groove is smaller than that of the first annular groove.
[0013] Specifically, the weight of the counterweight block in the second annular groove, i.e., the inner annular groove, is less than the weight of the counterweight block in the first annular groove, i.e., the outer annular groove. Based on the distribution of the annular groove positions, counterweight blocks of different specifications and weights are provided to make the adjustment of the swivel assembly more refined and more accurate.
[0014] Furthermore, the outer periphery of the plate body and the inner wall of the cylinder shell are interference fit.
[0015] Furthermore, the plate body is fixed to the cylinder shell by cold pressing.
[0016] Specifically, the assembly of the plate body and the cylinder shell is achieved by press-fitting.

[0017] Furthermore, the plate body and the rotating shaft are integrally formed.
[0018] In some embodiments, the number of the balancing support plates is set according to the length of the cylinder shell.
[0019] Specifically, the balance support plates can strengthen the structural strength of the cylinder shell. The number of balance support plates can be set to 2 groups, 3 groups or more, which is determined according to the length of the cylinder shell.
[0020] Furthermore, the balance support plate is arranged in a ring shape, and the weight of the balance support plate is reduced through the design of the ring structure.

[0028] The following is combined with Figures 1 to 3 , a detailed description of this application is given.
[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0030] The present application provides a swivel assembly for water drill grinding and polishing, which has at least the advantages of good structural strength, good inherent balance, convenient adjustment, and high flexibility.
[0031] See also Figure 1 Shown is a perspective view of a swivel assembly for water drill polishing provided by one embodiment of the present application.
[0032] Specifically, the present application provides a rotary assembly for water drill grinding and polishing, comprising: a barrel 10, a cover plate 20, a balance support plate 11 and a counterweight block 30, and its overall appearance is as follows: Figure 1 As shown. The plate body 21 of the cover plate 20 is fixedly connected to the two ends of the cylindrical shell 10, and the entire cylindrical shell 10 is driven to rotate through the coaxially arranged rotating shaft 22. The outer surface of the cylindrical shell 10 is provided with grinding materials or polishing materials according to different grinding and polishing processes, which are used for grinding and polishing the rhinestones. Among them, the counterweight block 30 is used to counterweight the entire swivel assembly. After the swivel assembly is processed, the swivel assembly is subjected to a rotational balance test. When the circular runout of the swivel assembly does not meet the preset threshold, according to the rotational balance test results, the counterweight blocks 30 of appropriate number and appropriate position are loaded to make the circular runout of the swivel assembly meet the preset threshold, thereby achieving the rotational balance of the swivel assembly.
[0033] In order to make the structure of the rotary assembly for water drill polishing provided by the present application more intuitive, please refer to Figure 2 Shown is a schematic cross-sectional view taken along the A axis of a swivel assembly for water drill polishing provided by another embodiment of the present application.
[0034] Specifically, one of the concepts of the present application is to improve the balance of the entire swivel structure itself through the structural design of the cylinder shell 10, the cover plate 20, and the balance support plate 11, to facilitate the adjustment of the swivel assembly through the counterweight block 30, and to improve the flexibility and simplicity of the rotational balance adjustment of the swivel assembly.
[0035] Furthermore, the counterweight slot 23 is configured as an internal threaded blind hole, and the counterweight block 30 is a screw.
[0036] Specifically, the counterweight block 30 adopts a screw structure, which is convenient for loading the counterweight block 30. According to the actual rotation balance of the swivel assembly, a suitable number of counterweight blocks 30 are loaded. At the same time, the screw-type counterweight block 30 can be directly assembled through the threaded hole of the counterweight slot 23 during actual operation, and loading and taking are very convenient and flexible.
[0037] Furthermore, the outer periphery of the plate body 21 and the inner wall of the cylinder shell 10 are in interference fit.
[0038] Furthermore, the plate body 21 is fixed to the cylinder shell 10 by cold pressing.
[0039] Specifically, the assembly of the plate body 21 and the cylinder shell 10 is achieved by press-fitting. Compared with the traditional welding method, the cylinder shell 10 is basically free of deformation, so that the basic balance performance of the entire swivel assembly is better and the stability is higher.
[0040] Furthermore, the plate body 21 and the rotating shaft 22 are integrally formed.
[0041] In some embodiments, the number of the balancing support plates 11 is set according to the length of the cylindrical shell 10 .
[0042] Specifically, the balance support plates 11 can strengthen the structural strength of the cylinder shell 10 . The number of the balance support plates 11 can be set to 2 groups, 3 groups or more, which is determined according to the length of the cylinder shell 10 .
[0043] Furthermore, the balance support plate 11 is configured in a ring shape, and the weight of the balance support plate 11 is reduced through the design of the ring structure.
[0044] Furthermore, the balance support plates 11 are provided in multiple groups and are symmetrically distributed along the length center line 26 of the cylinder shell 10 .
[0045] It is worth noting that only one group of balancing support plates 11 can be set, directly set on the length center line 26 of the cylindrical shell 10. When set to 2 groups, they are symmetrical along the length center line 26, so that the cylindrical shell 10 is roughly divided into 4 equal parts in the length direction. When set to 3 groups, one group is set on the length center line 26, and the other two groups are symmetrical along the length center line 26, so that the cylindrical shell 10 is divided into 5 equal parts in the length direction. The number of other balancing support plates 11 is set in the same way. The specific number of balancing support plates 11 is confirmed based on the length of the cylindrical shell 10 to ensure the overall structural strength of the cylindrical shell 10, to ensure that the cylindrical shell 10 is not deformed by external forces during actual use, and to ensure that the original balancing performance of the rotating assembly is not affected by long-term working use.
[0046] See also Figure 3 Shown is a schematic end view of a cover sealing plate 20 provided in another embodiment of the present application.
[0047] Specifically, the counterweight groove 23 includes a first annular groove 24 and a second annular groove 25, and the second annular groove 25 is located in the first annular groove 24. By setting the multi-layer annular groove, an adjustment groove for rotation balance under different torque conditions is provided.
[0048] Furthermore, the radius of the second annular groove 25 is smaller than that of the first annular groove 24 .
[0049] Specifically, the weight of the second annular groove 25, i.e., the inner annular groove counterweight 30, is less than the weight of the first annular groove 24, i.e., the outer annular groove counterweight 30. Based on the distribution of the annular groove positions, counterweights 30 of different specifications and weights are provided, so that the adjustment of the swivel assembly is more refined and more accurate.
