Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of stone pot processing equipment, and specifically relates to a coring device. BACKGROUND

[0002] Stone pot is a kind of cooking utensil made of natural stone (such as soapstone, medical stone, etc.), which is widely used in families and restaurants due to its unique heat preservation performance and health care function. In the preparation process of stone pot, a series of complex processes are needed, including material selection, processing and shaping, and coring, etc.

[0003] Traditional stone pot making is mostly manual operation, which mainly uses iron hatchet or chisel to chisel a groove on the stone to form the rudiment of stone pot, and then removes the excess part by manual carving and polishing to make the pot wall and bottom smooth. This processing method has many problems such as low efficiency, high labor cost and material waste.

[0004] With the development of technology, using mechanical equipment for coring has become a new trend of stone pot production. The traditional mechanical coring usually uses a drill bit to drill a ring-shaped groove on the stone, and then uses a diamond wire to grind the core in the ring-shaped groove. This processing method has many problems such as complex process, low flatness and concentricity of the cut surface, need to transfer the stone to different equipment and reposition, etc. Therefore, we developed a high-speed drilling and coring device and applied for a Chinese patent (publication number CN211334024U). The patent product realizes the whole process of drilling and coring on a single device through the concentrically arranged cutter barrels and the cutting knives arranged at the opening ends of the cutter barrels, and can process multiple stone pots at one time, significantly improving the production efficiency and processing precision. However, in the subsequent use process, we found that it still has problems, mainly in the following aspects: 1. It drives the rotating shaft to rotate through the first rotating mechanism. Specifically, the output end of the first driving part is connected to the first connecting plate, and then the first connecting plate drives the rack to move, and the rotating shaft rotates through the gear on the rotating shaft and the rack. This structure has the problems of complex structure and low transmission efficiency, and the cooperation of the rack and the gear requires high precision, especially during installation and adjustment. If the installation position of the rack or the gear is not accurate, it may cause unstable transmission, even the phenomenon of jamming or tooth falling off. In order to avoid the rack from deviating, it is necessary to set guide screws and other structures. In addition, the maintenance cost in the later stage is also high. 2. The cutter barrels are at least two concentrically arranged, and the rotating shafts on the same side are connected to a first rotating mechanism. This design is easy to cause uneven power distribution, which affects the cutting effect. Moreover, since multiple rotating shafts share a rotating mechanism, when the load is large, it is easy to cause overload or damage of the rotating mechanism, affecting the stability and service life of the equipment. 3. It is necessary to set a limiting mechanism to limit the cutting knife by tightening the nut to avoid the cutting knife from shaking during drilling. When drilling is completed and coring is carried out, the nut needs to be loosened to push the rotating shaft to the bottom of the ring-shaped groove, and then the subsequent cutting work can be carried out. The operation process is complex.

[0005] Therefore, the utility model is proposed. Utility model content

[0024] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the utility model is further described in detail below, the schematic embodiment and its description of the utility model are only used to explain the utility model, and do not serve as the limitation of the utility model.

[0025] As Figures 1 to 7 The utility model provides a kind of coring device, it includes and only one cylinder 1, cylinder 1 inside hollow, one end is open end, the other end is connected and is provided with mounting plate 2, mounting plate 2 is provided with power mechanism 3, the output end of power mechanism 3 is connected with rotating shaft 11, rotating shaft 11 rotatably set in the wall of cylinder 1, it is connected with the cutting knife 9 of open end place from power mechanism 3 position place extension and is arranged at open end under the action of power mechanism 3, cutting knife 9 can be rotated between first position and second position, realizes coring cutting.

[0026] It should be noted that in the prior art, the traditional mechanical coring is usually to drill a ring groove on the stone by a drill bit, and then to grind the core in the ring groove with a diamond wire, which has many problems such as complex process. Our patent product (its publication number is CN211334024U) at least contains two concentrically arranged cutter barrels, which has the problem of uneven power distribution, which can easily cause uneven cutting surface and affect product quality. Therefore, in the present scheme, the barrel body 1 is provided to be only one. It should be noted that the first position may be, for example, a non-cutting position, such as the position shown in Figure 2 , and the second position may be, for example, the maximum cutting position after the cutting knife 9 is rotated out.

[0027] It should be noted that the core taking device of the utility model, the opening end of the barrel body 1 can be selectively provided with a tooth block 10 (that is, it can be provided or not provided); when the tooth block 10 is provided, the cutting knife 9 is located between the adjacent tooth blocks 10, at this time, the tooth block 10 can be used for drilling and chiseling a ring groove, and the core taking and cutting can be completed at one time after drilling and chiseling. When the tooth block 10 is not provided, the core taking device can be placed in the drilled ring groove for core taking and cutting. It should be noted that the power mechanism 3, the rotating shaft 11 and the cutting knife 9 can be provided in plurality, and the power mechanism 3, the rotating shaft 11 and the cutting knife 9 are in one-to-one correspondence, so that each cutting knife 9 is controlled by the corresponding power mechanism 3, avoiding the problem of uneven power distribution.

[0028] In order to better achieve the purpose of the utility model, the rotating axis of the output end of the power mechanism 3 coincides with the axis of the rotating shaft 11. In this way, the device can ensure high power transmission efficiency, and the operation stability of the device is higher.

[0029] In a preferred embodiment, the power mechanism 3 is a rotating head, which includes a stator 13 and a rotor 14 rotatably arranged in the stator 13, the rotating shaft 11 is directly connected with the rotor 14, and the axis of the rotating shaft 11 coincides with the rotating axis of the rotor 14, as shown in Figure 4 and Figure 5 . Further, the power mechanism 3 further includes a mounting seat 12, the mounting seat 12 is fixedly connected (preferably detachably) with the bottom of the stator 13, the bottom of the rotor 14 is formed with an outwardly protruding ring table part 18, and the ring table part 18 is limited between the stator 13 and the mounting seat 12, thereby limiting the movement of the rotating shaft 11 in the axis direction. See Figure 5, through such a setting mode, the rotating shaft 11 is directly connected with the bottom of the rotor 14, and the ring table part 18 is arranged so that the rotating shaft 11 cannot move in the vertical direction and can only rotate in the circumferential direction following the rotor 14. Thus, the transmission efficiency can be greatly improved, the power mechanism 3 is simple in structure, the movement precision can be ensured, and the maintenance cost in the later period is greatly reduced. It should be noted that, by adopting such a setting mode, the rotating shaft 11 is directly suspended by the rotor 14, so that it does not need to be provided with a nut or the like, and the rotation of the cutting knife 9 is directly controlled by the rotation of the rotor 14, which can realize automatic control without adjusting the nut as in the prior patent product.

[0030] Further, the power mechanism 3 is detachably arranged on the mounting plate 2 through the mounting seat 12. In addition, since the rotating shaft 11 is rotatably arranged in the wall of the barrel 1, when the power mechanism 3 with the above structure is adopted, in order to ensure that the power mechanism 3 can be stably mounted and prevent it from being partially suspended, the mounting plate 2 is further formed with an outer edge extension 7 on the outer circumferential side of the barrel 1. Preferably, the thickness of the outer edge extension 7 in the vertical direction, i.e., the second thickness, is smaller than the thickness of the main body part of the mounting plate 2, i.e., the first thickness H (see Figure 4 The main body part of the mounting plate 2 has sufficient thickness, mainly to ensure the stability of the entire barrel). It should also be understood that the mounting plate 2 is provided with a connecting part 4 for connection with a machine tool or the like.

[0031] In a preferred embodiment, a plurality of through holes 8 are uniformly distributed in a circumferential array on the outer edge extension 7. The through holes 8 are mainly used to facilitate the insertion of a rod or the like adjusting device during the later maintenance process, for example, after the core taking device is taken off from the machine tool, the rod is used to rotate the core taking device to adjust its posture.

[0032] In order to better achieve the purpose of the utility model, the stator 13 is formed with a first opening 5 and a second opening 6, the middle outer circumference of the rotor 14 is formed with a C-shaped incomplete ring groove 16, the first opening 5 and the second opening 6 are respectively communicated with the C-shaped incomplete ring groove 16 through a channel 17, and the stator 13 is further formed with a sliding table 20 inwardly at the position of the C-shaped incomplete ring groove 16. The sliding table 20 is inserted into the C-shaped incomplete ring groove 16 and is in sliding cooperation (preferably sealed sliding cooperation) with the groove bottom of the C-shaped incomplete ring groove 16, and the sliding table 20 divides the C-shaped incomplete ring groove 16 into a first cavity D and a second cavity E which are isolated from each other, the first opening 5 is communicated with the first cavity D, and the second opening 6 is communicated with the second cavity E. Through such a setting, fluid can be injected into the corresponding first cavity D and second cavity E through the first opening 5 or the second opening 6 to realize the rotation of the rotor 14, for example, in Figure 7When the fluid with pressure is injected into the first cavity D through the first opening 5, the rotor 14 rotates in the clockwise direction, and vice versa, when the fluid with pressure is injected into the second cavity E through the second opening 6, the rotor 14 rotates in the counterclockwise direction.

[0033] It is to be noted that the C-shaped non-complete annular groove 16 is formed on the outer circumference of the rotor 14, and the non-complete annular groove is formed by the partition 161. Referring to Figure 6 If the partition 161 is also machined to be removed, it will become a complete annular groove. On this basis, referring to Figure 7 The two sides of the sliding table 20 are respectively formed with the limiting stop table 19, the limiting stop table 19 in the first cavity D is formed with the first limiting surface 191 matched with the partition 161, the limiting stop table 19 in the second cavity E is formed with the second limiting surface 192 matched with the partition 161, and the rotation of the rotor 14 is limited between the first limiting surface 191 and the second limiting surface 192. Further, the limiting stop table 19 and the bottom of the C-shaped non-complete annular groove 16 are provided with the first gap 21, and the channels 17 corresponding to the first opening 5 and the second opening 6 are all connected to the first gap 21. Through such a setting, the rotation of the rotor 14 is limited between the first limiting surface 191 and the second limiting surface 192, so that the cutting knife 9 can be controlled to rotate between the first position and the second position. For example, by setting, when the partition 161 of the rotor 14 moves to the first limiting surface 191, the cutting knife 9 is just located at the first position, and when the partition 161 of the rotor 14 moves to the second limiting surface 192, the cutting knife 9 is just located at the second position. In this way, the problem of complex structure and operation process caused by the need to set nuts, limiting mechanisms and the like in the prior art is avoided. Since the position of the rotor 14 is controlled by fluid pressure, only a predetermined fluid pressure needs to be applied through the first opening 5 or the second opening 6 to limit the cutting knife 9 at a predetermined position and avoid its shaking during drilling.

[0034] Preferably, above and below the C-shaped non-complete annular groove 16, a plurality of bearings are arranged in rotational cooperation between the rotor 14 and the stator 13, and annular sealing rings are arranged between each bearing and the bearing and between the bearing and the C-shaped non-complete annular groove 16 to isolate each other. Such a way is mainly to avoid the mutual influence between the bearings and the bearings and between the bearings and the C-shaped non-complete annular groove 16. This influence not only comes from the fluid at the C-shaped non-complete annular groove 16, but also comes from some small particles such as dust during the rotational cooperation.

[0035] Further, the top of the stator 13 is further provided with a cover 15 which at least covers the position of the rotational cooperation between the rotor 14 and the stator 13. This is mainly to avoid the entry of dust and the like from the outside, affecting the service life of the power mechanism.

[0036] It should also be understood that, since the position of the cutting knife 9 is adjusted by the power mechanism 3, the cutting knife 9 does not need to be limited by the limiting mechanism as in our previously applied patent (publication number CN211334024U), nor does it need to set a nut to fix the shaft. Therefore, its structure is simpler and more convenient to operate compared to the prior art. In addition, in some embodiments, there can be a second gap L between the top surface of the cutting knife 9 and the bottom surface of the cylinder 1 at the corresponding position of the open end, without having to be immediately together, which can facilitate subsequent adjustment of the cutting knife 9. In addition, in some embodiments, a tooth block 10 can be provided, and the bottom surface of the cutting knife 9 is slightly higher than the bottom surface of the tooth block 10, and the distance between the two is Figure 4 The vertical distance S is shown, which can be determined by actual processing.

[0037] Further, the rotor 14 can be provided in two sections, or the stator 13 is provided in two sections, to facilitate the corresponding cooperation between the stator 13 and the rotor 14. This is prior art and will not be described in detail.

[0038] Finally, it should be noted that in this document, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that processes, methods, articles or devices that include a series of elements not only include those elements, but also include other elements not explicitly listed, or inherent to such processes, methods, articles or devices.

[0039] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application should not be limited to the embodiments shown herein, but should be consistent with the widest scope of the principles and novel features disclosed herein.
