[0002] A sandblasting device generally refers to a sandblaster, which can use compressed air in a pipeline to transport powdery granular materials from one place to another.

Detailed implementation manners

[0056] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0057] Refer to the attachedFigure 1 - Attached Figure 10 In an embodiment of the present utility model, a multi-angle sandblasting device is disclosed, which includes a frame body 1, and further includes a first moving mechanism 2, a driving mechanism 3, and a second moving mechanism 4. The first moving mechanism 2 is installed on the frame body 1, and a plurality of fixing components 5 are rotatably connected thereto. The fixing components 5 are used to fix the parts to be processed. The driving mechanism 3 is installed on the frame body 1 and is arranged corresponding to the first moving mechanism 2. The driving mechanism 3 is drivingly connected to the fixing components 5 to drive the fixing components 5 to rotate. The second moving mechanism 4 is installed on the frame body 1, and a nozzle assembly 6 is drivingly connected thereto. The nozzle assembly 6 includes a plurality of nozzles 61 at different angles. The plurality of nozzles 61 are all connected to a pressure-fed sandblasting system, and can perform sandblasting operations and approach or move away from the parts to be processed on the fixing components 5 under the drive of the second moving mechanism 4.

[0058] During the actual practical process, the parts to be processed are respectively installed on the plurality of fixing components 5. The first moving mechanism 2 on the frame body 1 is started to drive one of the fixing components 5 to be connected to the driving mechanism 3. Then the driving mechanism 3 is started to rotate the fixing component 5 and the part. Next, the second moving mechanism 4 is started to move the nozzle assembly 6 to a specified position. Then, under the action of the pressure-fed sandblasting system, the plurality of nozzles 61 respectively eject sand grains from multiple angles to wash the rotating part, thereby improving the quality of each surface of the part. This not only eliminates the need for manual operation but also ensures uniform sandblasting treatment. In addition, for parts with a longer length, the nozzle assembly 6 can be moved by the second moving mechanism 4 to change the sandblasting position, so that the sandblasting area can cover the entire surface of the part. After one part is processed, the first moving mechanism 2 can be started again to drive the adjacent next fixing component 5 to be connected to the driving mechanism 3, and then a new part can be processed. The processed part can be removed from the fixing component 5 and an unprocessed part can be installed, so as to achieve the purpose of continuous processing. Generally speaking, by using this multi-angle sandblasting device, multiple parts to be processed can be continuously subjected to multi-angle automatic sandblasting work, saving time and effort.

[0059] In order to more clearly illustrate the advantages of this multi-angle sandblasting device, taking a dental screw as an example of the part to be processed. Since there are multiple turns of threads on the side of the dental screw, even if the dental screw is continuously rotated, one nozzle 61 cannot wash the entire surface of the dental screw. It can only wash the upper surface of the thread, the lower surface of the thread, and the side surface of the dental screw in sequence, which is time-consuming and laborious. However, by using a plurality of nozzles 61 at different angles to perform sandblasting operations simultaneously, such as setting three nozzles 61, one sandblasting obliquely upward, one sandblasting obliquely downward, and one sandblasting horizontally, the washing area of the nozzles 61 can completely cover one side surface of the dental screw, so that the entire surface of the dental screw can be washed during the rotation of the dental screw.

[0060] It should be noted that the above-mentioned pressure-fed sandblasting system adopts existing technologies, including a medium power system, a pipeline system, a control system, and multiple pressure tanks corresponding to the nozzles 61 one by one, which will not be elaborated here in detail; in addition, since the pressure-fed sandblasting technology is adopted in this embodiment, this multi-angle sandblasting device is applicable to parts with a one-time use requirement for the particle size of the sandblasting abrasive, and the final parts have higher precision.

[0061] Furthermore, a sensor can be set to sense the presence of parts at the working station, so as to automatically process the parts. This solution is an existing technology and will not be elaborated here in detail; the above-mentioned working station specifically refers to the position above the fixed component 5 that is drivingly connected to the driving mechanism 3. The working stations mentioned below are the same as this working station.

[0062] In order to enable the first moving mechanism 2 to drive the fixed component 5 to move, so that multiple fixed components 5 can be sequentially drivingly connected to the driving mechanism 3, the following design is carried out in this embodiment. Specifically, the first moving mechanism 2 includes a first motor 21 and a turntable 22. The first motor 21 is installed on the frame 1 and is vertically arranged. Its output shaft is rotationally connected to the frame 1 and one end passes through the frame 1; the cross-section of the turntable 22 is circular and the center part thereof is fixedly connected to the output shaft of the first motor 21, so that the turntable 22 can rotate under the drive of the first motor 21, and the turntable 22 is rotationally connected to the fixed component 5.

[0063] When using the first moving mechanism 2, start the first motor 21, which can drive the turntable 22 to rotate, thereby indirectly driving the fixed component 5 to rotate around the output shaft of the first motor 21, so that multiple fixed components 5 can sequentially move to the above-mentioned working station.

[0064] Refer to Appendix Figure 1 、Appendix Figure 3 、Appendix Figure 5 and Appendix Figure 6 In order to enable the fixed component 5 to fix the parts, the following design is carried out in this embodiment. Specifically, the fixed component 5 includes a rotating member 51 and a fixing member 52. The rotating member 51 is rotationally connected to the turntable 22; the fixing member 52 is detachably connected to the rotating member 51 and can be drivingly connected to the driving mechanism 3 for fixing the parts to be processed. The fixing member 52 has multiple types and can respectively fix multiple parts to be processed.

[0065] Through the design of the above structure, when processing different parts, different types of fixing members 52 can be selected and installed on the rotating member 51, which is applicable to the batch automatic sandblasting treatment of multi-variety small parts.

[0066] In order to enable each rotating member 51 to move to the working station and ensure that the interval time between the processing of two adjacent parts is the same, the following design is made in this embodiment. Specifically, there are six rotating members 51, which are arranged in a circular array on the turntable 22.

[0067] Based on the above solution, in order to detachably connect the rotating member 51 and the fixing member 52 and enable the fixing member 52 to fix the part to be processed, the following design is made in this embodiment. Specifically, the bottom of the rotating member 51 is rotatably connected to the turntable 22, and a first protrusion 511 is provided at the top. A first groove 521 is provided at the bottom of the fixing member 52, and a second groove 522 is provided at the top. The first protrusion 511 is in a damped sliding connection with the first groove 521, so that the first protrusion 511 can be inserted into the first groove 521 to fix the relative positions of the rotating member 51 and the fixing member 52. The second groove 522 is arranged corresponding to the part to be processed and is in a damped sliding connection with one end of the part to be processed, so that one end of the part to be processed can be inserted into the second groove 522 to fix the relative positions of the fixing member 52 and the part to be processed, enabling the part to be processed to move simultaneously with the rotating member 51.

[0068] Through the design of the above structure, the fixing member 52 can be directly connected and fixed to or detached from the rotating member 51 by plugging and unplugging. Similarly, the part to be processed can be connected and fixed to or detached from the fixing member 52 in the same way. The structure is simple, the connection is reliable, and the disassembly and assembly are convenient.

[0069] It should be noted that in order to enable the fixing member 52 and the rotating member 51 to be detachably connected by plugging and unplugging and ensure the stability after connection, at least one of the fixing member 52 and the rotating member 51 needs to be made of an elastic material, and the same is true for the fixing member 52 and the part to be processed. Since the materials of the parts are diverse, for more convenient connection, the fixing member 52 in this embodiment is made of an elastic material. During specific connection, the first groove 521 can generate a tightening force on the first protrusion 511, and the second groove 522 can generate a tightening force on one end of the part to be processed, so that the part to be processed will not fall off during rotation and being scoured by abrasive grains.

[0070] The shapes of some parts are relatively slender. If the size of the fixing member 52 is large, it may cause the sand grains ejected from some nozzles 61 with an angle to fail to reach the surface of the parts. In order to avoid the influence of the fixing member 52 on the nozzle 61 as much as possible, in this embodiment, the lower part of the fixing member 52 can be set to be cylindrical, and the upper part is set to be a frustum of a cone, and the bottom diameter of the frustum of the cone is larger than the top diameter, so that the sand grains ejected from the inclined nozzle 61 can reach the surface of the parts; further, the ends of some parts are recessed inward. In order to avoid the size of the second groove 522 being too large, resulting in an increase in the size of the fixing member 52, a second protrusion can also be provided on the fixing member 52, and the second protrusion is connected to the recessed part of the end of the part in a damped sliding manner, so as to fix the part to be processed.

[0071] Refer to the appendix Figure 1 - appendix Figure 3 In order to enable the driving mechanism 3 to provide rotational power for the fixing component 5 at the working station, the following design is carried out in this embodiment. Specifically, the driving mechanism 3 includes a driving motor 31, two rotating shafts 32, two belt pulleys 33, and a belt 34. The driving motor 31 is installed on the frame 1 and is vertically arranged; both rotating shafts 32 are rotatably connected to the frame 1, and one of the rotating shafts 32 is drivingly connected to the driving motor 31; the two belt pulleys 33 are respectively fixedly connected to the two rotating shafts 32; the belt 34 is installed on the two belt pulleys 33, the inner side of which is in damped sliding connection with the belt pulley 33, and the outer side of which is in damped sliding connection with the rotating member 51, so that the belt pulley 33 can drive the belt 34 to move under the drive of the driving motor 31, thereby indirectly driving the rotating member 51 to rotate.

[0072] When using the driving mechanism 3, start the driving motor 31, which can drive one rotating shaft 32 and the belt pulley 33 thereon to rotate. Since the inner side of the belt 34 is in damped sliding connection with the belt pulley 33, the other rotating shaft 32 and the belt pulley 33 thereon will also rotate accordingly, so that the belt 34 is tightened and continuously moves under the action of the two belt pulleys 33. Also, since the outer side of the belt 34 is in damped sliding connection with the rotating member 51, and the rotating member 51 is rotatably connected to the turntable 22, the belt 34 can drive the rotating member 51 to rotate, so that the fixing member 52 and the part to be processed rotate and are sandblasted by the nozzle assembly 6 during the rotation.

[0073] Refer to the appendix Figure 1 - appendix Figure 4, in order to enable the second moving mechanism 4 to drive the nozzle assembly 6 to approach or move away from the working station, the following design is carried out in this embodiment. Specifically, the second moving mechanism 4 includes two fixing plates 41, a second motor 42, a screw 43, a guide rod 44, and a moving member 45. The two fixing plates 41 are both installed on the frame 1 and arranged linearly in the vertical direction; the second motor 42 is installed at the bottom of the lower fixing plate 41, and its output shaft is rotatably connected to the lower fixing plate 41; the screw 43 is rotatably connected between the two fixing plates 41, the screw 43 is vertically arranged and is drivingly connected to the second motor 42, so that the screw 43 can be rotated under the drive of the second motor 42; the guide rod 44 is fixedly connected between the two fixing plates 41 and is vertically arranged; the moving member 45 is provided with a threaded hole 451 and is engaged on the screw 43, the moving member 45 is provided with a guide hole 452 and is slidably connected to the side of the guide rod 44, and the moving member 45 is fixedly connected to the nozzle assembly 6, so that the moving member 45 can move along the direction of the guide rod 44 with the rotation of the screw 43, thereby driving the nozzle assembly 6 to approach or move away from the part to be processed.

[0074] When using the second moving mechanism 4, start the second motor 42 on the lower fixing plate 41, which can drive the screw 43 to rotate, so that the moving member 45 and the nozzle assembly 6 move along the guide rod 44, thereby making the nozzle assembly 6 approach or move away from the workpiece to be processed.

[0075] Refer to the appendix Figure 1 and the appendix Figure 2 and the appendix Figure 9 , since the sandblasting device will eject fine sand grains during use, these sand grains will continuously spread during the process of scouring the part and are easily attached to the second moving mechanism 4, thereby affecting the movement of the nozzle assembly 6. To solve the above problems, the following design is carried out in this embodiment. Specifically, it further includes two bellows protective covers 7. The two bellows protective covers 7 are both sleeved outside the screw 43 and the guide rod 44, and are respectively arranged between the moving member 45 and the upper fixing plate 41, and between the moving member 45 and the lower fixing plate 41, so that the screw 43 and the guide rod 44 are in a sealed chamber to prevent sand grains from adhering to the surfaces of the screw 43 and the guide rod 44, thereby affecting the movement of the moving member 45.

[0076] Through the design of the above structure, the screw 43 and the guide rod 44 can be protected without affecting the movement of the moving member 45 and the nozzle assembly 6, and it is more convenient to use.

[0077] Refer to the appendix Figure 1 and the appendix Figure 2 and the appendix Figure 10, in order to enable the nozzle 61 in the nozzle assembly 6 to be flexibly adjusted according to variables such as the shape, size, and spatial position of the part, the following design is carried out in this embodiment. Specifically, the nozzle assembly 6 includes multiple nozzles 61, multiple connecting rods 62, and multiple adapters 63. One end of the nozzle 61 is cylindrical and is connected to the pressure-fed sandblasting system by a hose; the connecting rod 62 is cylindrical; the adapter 63 is provided with two connecting parts, the two connecting parts are rotationally connected with damping, and the connecting part is slidably connected with damping to the connecting rod 62 or the nozzle 61.

[0078] When specifically adjusting the nozzle assembly 6, the adapter 63 cooperates with the connecting rod 62 to change the spatial position of the nozzle 61, so that the sand grains ejected by the nozzle 61 can scour the surface of the part to be machined. The two connecting parts cooperate to change the sandblasting angle of the nozzle 61, so that the nozzle 61 can eject sand grains from multiple angles relative to the part to be machined.

[0079] Refer to the appendix Figure 7 and the appendix Figure 8 , in order to more clearly illustrate the structure of the adapter 63 and its connection method with other components, the following design is carried out in this embodiment. Specifically, the adapter 63 includes two connectors 631, a first bolt 632, and a second bolt 633. Both of the two connectors 631 are provided with a through slot 8, a through hole 9 communicating with the through slot 8, and a first threaded hole 10 corresponding to the through slot 8. The through hole 9 is slidably connected with damping to the connecting rod 62 or the nozzle 61. One of the connectors 631 is provided with a rotating part 11 with a circular cross-section. The other connector 631 is provided with a rotating slot 12 corresponding to the rotating part 11 and a second threaded hole 13. The two connectors 631 are rotationally connected through the rotating part 11 and the rotating slot 12; the first bolt 632 is engaged in the first threaded hole 10; the second bolt 633 is engaged in the second threaded hole 13.

[0080] When using the adapter 63, by tightening the first bolt 632, the connector 631 can be deformed at the through slot 8, and the size of the through hole 9 can be reduced, so as to lock and fix the connecting rod 62 or the nozzle 61; by tightening the second bolt 633, the end of the second bolt 633 can be abutted against and tightened against the rotating part 11, so as to fix the relative positions of the two connectors 631.

[0081] It should be noted that, in order to enable the connector 631 to be deformed at the through slot 8, the connector 631 needs to be made of a material that can undergo elastic deformation; in addition, in order to prevent the rotating part 11 from disengaging from the rotating slot 12, the cross-section of the rotating part 11 can be set to be T-shaped.
