Description

Technical Field

[0001] This application belongs to the field of magnetic pump component processing fixture technology, and particularly relates to a support device for thin-walled encapsulation processing of magnetic pumps. Background Technology

[0002] In magnetic pumps, the magnetic coupling is the core component of the transmission system, transmitting power through magnetic torque generated by magnets mounted on the inner and outer rotor components. The protection and encapsulation technology of the magnets is one of the key technologies for ensuring the long-term reliable operation of the equipment. To protect the magnets from environmental corrosion, a metal encapsulation process is typically used to seal them. This process often uses corrosion-resistant metals such as stainless steel, completely encapsulating the magnets through welding, effectively isolating them from oxygen and corrosive media. However, due to the stringent requirements of magnetic pumps for compact structure and transmission efficiency, the wall thickness of the magnet encapsulation is limited to the range of 0.6–1 mm. This ultra-thin wall structure makes the encapsulated parts extremely prone to deformation during processing, significantly increasing processing difficulty and leading to low yield, becoming a technical bottleneck restricting the development of the magnetic pump industry. Therefore, it is necessary to solve the above-mentioned technical problems. Utility Model Content

[0003] The purpose of this application is to provide a support device for thin-wall encapsulation processing of magnetic pumps, so as to solve the technical problem of low yield in thin-wall encapsulation processing in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a support device for thin-wall encapsulation processing of magnetic pumps, comprising:

[0005] Mounting plate;

[0006] A tensioning screw is threaded onto the clamping plate and parallel to the axial direction of the clamping plate;

[0007] The pressure block forms a hole through which the tensioning screw passes and abuts against the end of the tensioning screw away from the clamping plate. The pressure block also forms a tapered outer surface that is close to the clamping plate at the small end and coaxial with the tensioning screw.

[0008] An outer ring is formed, which has a conical inner surface adapted to the conical outer surface and a cylindrical outer surface coaxial with the conical inner surface. The outer ring is fitted onto the pressure block and abuts against the conical outer surface through the conical inner surface. The large end of the conical inner surface is close to the clamping plate. Several notches are formed on the outer ring, which are evenly distributed around its central axis.

[0009] Optionally, the magnetic pump thin-wall encapsulation processing support device further includes a guide post connected to the clamping plate;

[0010] The axial direction of the guide post is parallel to the axial direction of the tensioning screw, and the pressure block has a guide hole adapted to the guide post, and the pressure block is slidably connected to the guide post through the guide hole.

[0011] Optionally, multiple sets of guide posts and guide holes are evenly spaced around the central axis of the tensioning screw.

[0012] Optionally, the magnetic pump thin-wall encapsulation processing support device further includes a thrust cover, which is connected to the pressure block and used to cooperate with the clamping plate to clamp the target thin-wall encapsulation that is coaxially fitted on the outer ring;

[0013] A connecting hole connected to the guide hole is also formed on the pressure block;

[0014] The connecting hole penetrates the pressure block to allow the guide hole to communicate with the atmosphere.

[0015] Optionally, a threaded hole is also formed on the pressure block, which communicates with the connecting hole. The connecting hole is disposed between the guide hole and the threaded hole and communicates with the atmosphere through the threaded hole.

[0016] The magnetic pump thin-wall encapsulation support device also includes a bolt threaded to the threaded hole, and the thrust cover is detachably connected to the pressure block through the bolt.

[0017] Optionally, the bolt's axial direction is parallel to the tensioning screw, and a flange coaxial with itself is formed on the bolt;

[0018] The magnetic pump thin-wall encapsulation support device also includes a spring coaxially mounted on the bolt, with the two ends of the spring along its own elastic force direction respectively abutting against the thrust cover and the flange.

[0019] Optionally, the bolt forms a threaded portion for threaded connection with the threaded hole, and also forms a smooth portion that extends into the communicating hole and is slidably connected with the communicating hole.

[0020] Optionally, the clamping disc is used to form a step on the side that abuts against the target thin-walled enclosure;

[0021] The step is shaped to fit the target thin-walled enclosure and is used to abut against the inner wall surface of the target thin-walled enclosure.

[0022] Optionally, the length of the notch is at least three-quarters of the total length of the outer ring.

[0023] Optionally, several of the notches extend alternately to the two end faces of the outer ring in a direction parallel to the central axis of the outer ring.

[0024] The beneficial effects of the magnetic pump thin-wall encapsulation processing support device provided in this application are as follows: Compared with the prior art, in the magnetic pump thin-wall encapsulation processing support device provided in this application, the tension screw threaded to the clamping plate can rotate relative to the clamping plate to drive the pressure block that abuts against it to move closer to the clamping plate along the axial direction of the tension screw. In this way, the thrust plate connected to the pressure block can cooperate with the clamping plate to gradually form a stable clamping of the target thin-wall encapsulation coaxially fitted on the outer ring. Since the pressure block and the outer ring form mutually adaptable conical outer surface and conical inner surface, as the pressure block gradually moves closer to the clamping plate, the mutually adaptable conical outer surface and conical inner surface can enable the pressure block to form a stable support for the outer ring. Thus, the outer ring can also provide stable radial support for the target thin-wall encapsulation through its own cylindrical outer surface. This enables the magnetic pump thin-wall encapsulation processing support device in this application to effectively ensure that the target thin-wall encapsulation does not undergo structural deformation during the processing of the target thin-wall encapsulation, thereby significantly improving the processing yield of thin-wall encapsulation, which is far superior to the prior art.

[0034] Please refer to the following: Figures 1 to 3 The following describes a support device for thin-wall encapsulation processing of a magnetic pump, provided in an embodiment of this application. This support device includes a clamping plate 101, a tensioning screw 102, a pressure block 103, an outer ring 104, and a thrust cover 105. Wherein:

[0035] The tension screw 102 is threaded onto the clamping plate 101 and parallel to the axial direction of the clamping plate 101; the pressure block 103 forms a hole through which the tension screw 102 passes and abuts against the end of the tension screw 102 away from the clamping plate 101; the pressure block 103 also forms a tapered outer surface 131 with its small end close to the clamping plate 101 and coaxial with the tension screw 102; the outer ring 104 forms a tapered inner surface 141 adapted to the tapered outer surface 131, and also forms a cylindrical outer surface 142 coaxial with the tapered inner surface 141; the outer ring 104 is fitted onto the pressure block 103 and abuts against the tapered outer surface 131 through the tapered inner surface 141; the large end of the tapered inner surface 141 is close to the clamping plate 101; a number of notches 143 are evenly distributed around its central axis on the outer ring 104. According to the structure provided in this embodiment, the notch 143 provided on the outer ring 104 can facilitate the uniform expansion and deformation of each part of the outer ring 104 along its own axial direction along the radial direction of the outer ring 104. This can make the outer ring 104 provide more stable support for the target thin-walled encapsulation 200, which is also conducive to further improving the processing yield of the thin-walled encapsulation.

[0036] According to the structure provided in this embodiment, in the magnetic pump thin-wall encapsulation processing support device provided in this embodiment, the tension screw 102 threaded to the clamping plate 101 can rotate relative to the clamping plate 101 to drive the pressure block 103 that abuts against it to move closer to the clamping plate 101 along the axial direction of the tension screw 102. In this way, the thrust plate connected to the pressure block 103 can cooperate with the clamping plate 101 to gradually form a stable clamping of the target thin-wall encapsulation 200 coaxially fitted on the outer ring 104. Since the pressure block 103 and the outer ring 104 have mutually adapted conical outer surfaces 131 and conical inner surfaces 141, as the pressure block 103 gradually approaches the clamping plate 101, the mutually adapted conical outer surfaces 131 and conical inner surfaces 141 can enable the pressure block 103 to provide stable support for the outer ring 104. Thus, the outer ring 104 can provide stable radial support for the target thin-walled encapsulation 200 through its own cylindrical outer surface 142. This enables the magnetic pump thin-walled encapsulation processing support device in this embodiment to effectively ensure that the target thin-walled encapsulation 200 does not undergo structural deformation during the processing of the target thin-walled encapsulation 200, which is also beneficial to significantly improve the processing yield of thin-walled encapsulation, which is far superior to the prior art.

[0037] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3The magnetic pump thin-wall encapsulation processing support device also includes a guide post 106 connected to the clamping plate 101; the axial direction of the guide post 106 is parallel to the axial direction of the tension screw 102, and a guide hole 132 adapted to the guide post 106 is formed on the pressure block 103, and the pressure block 103 is slidably connected to the guide post 106 through the guide hole 132. According to the above structure provided in this embodiment, the guide post 106 connected to the clamping plate 101 can effectively improve the movement stability of the pressure block 103, which is conducive to making the outer ring 104 form a more stable support for the target thin-wall encapsulation 200, thereby also conducive to further improving the processing yield of thin-wall encapsulation.

[0038] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 Multiple sets of guide posts 106 and guide holes 132 are evenly spaced around the central axis of the tension screw 102. According to the structure provided in this embodiment, the cooperation of multiple sets of guide posts 106 and guide holes 132 can further improve the movement stability of the pressure block 103, which is beneficial for the outer ring 104 to form a more stable support for the target thin-walled encapsulation 200, and thus also beneficial for further improving the processing yield of the thin-walled encapsulation.

[0039] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The magnetic pump thin-wall encapsulation processing support device also includes a thrust cover 105, which is connected to the pressure block 103 and used to cooperate with the clamping plate 101 to clamp the target thin-wall encapsulation 200 coaxially mounted on the outer ring 104. The pressure block 103 also forms a connecting hole 133 that communicates with the guide hole 132; the connecting hole 133 penetrates the pressure block 103 to allow the guide hole 132 to communicate with the atmosphere. According to the above structure provided in this embodiment, the connecting hole 133 communicating with the atmosphere can prevent excessive air pressure in the guide hole 132, which can make the guide post 106 move more stably in the guide hole 132, thereby helping to further improve the processing yield of thin-wall encapsulation. It is understood that the outer diameter of the thrust cover 105 is smaller than the outer diameter of the target thin-wall encapsulation 200, and the inner diameter of the thrust cover 105 is larger than the outer diameter of the outer ring 104. At the same time, a through hole is provided on the end face of the thrust cover 105 to facilitate the insertion of tools to rotate the tightening screw 102.

[0040] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3The pressure block 103 also has a threaded hole 134 connected to the connecting hole 133. The connecting hole 133 is located between the guide hole 132 and the threaded hole 134 and communicates with the atmosphere through the threaded hole 134. The magnetic pump thin-wall encapsulation processing support device also includes a bolt 107 threadedly connected to the threaded hole 134. The thrust cover 105 is detachably connected to the pressure block 103 through the bolt 107. According to the structure provided in this embodiment, the threaded hole 134 on the pressure block 103 can not only communicate with the atmosphere through the connecting hole 133, but also be used to install the bolt 107. In this way, the thrust cover 105 can be detachably connected to the pressure block 103, which facilitates replacement and maintenance, and also helps to further improve the processing yield of thin-wall encapsulation.

[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The bolt 107 is axially parallel to the tension screw 102, and a flange 171 coaxially formed on the bolt 107. The magnetic pump thin-wall encapsulation processing support device also includes a spring 108 coaxially mounted on the bolt 107. The two ends of the spring 108 along its own elastic force direction abut against the thrust cover 105 and the flange 171, respectively. According to the above structure provided in this embodiment, the spring 108 mounted on the bolt 107 can, on the one hand, move the thrust cover 105 toward the clamping plate 101 under the drive of the flange 171, and before the outer ring 104 tightens and fixes the target thin-wall encapsulation 200, make the end face of the target thin-wall encapsulation 200 abut against the clamping plate 101 to complete the axial positioning of the target thin-wall encapsulation 200. On the other hand, the spring 108 can also prevent the thrust cover 105 from applying excessive pressure on the target thin-wall encapsulation 200 by contraction, which is beneficial to further improve the processing yield of thin-wall encapsulation.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The bolt 107 forms a threaded portion 172 for threaded connection with the threaded hole 134, and also forms a smooth shank portion 173 that extends into and slides through the connecting hole 133. According to the structure provided in this embodiment, in addition to being threadedly connected to the threaded hole 134 via its threaded portion 172, the bolt 107 can also be slidably connected to the guide hole 132 via its smooth shank portion 173 extending into the guide hole 132. Thus, the stepped end face at the junction of the smooth shank portion 173 and the threaded portion 172 can abut against the bottom surface of the threaded hole 134 when the bolt 107 is tightened, forming a secure threaded connection. This significantly improves the movement stability of the thrust cap 105 and further improves the processing yield of the thin-walled encapsulation.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3The clamping plate 101 has a step 109 formed on the side that abuts against the target thin-walled enclosure 200. The step 109 is shaped to fit the target thin-walled enclosure 200 and abuts against the inner wall surface of the target thin-walled enclosure 200. According to the structure provided in this embodiment, the step 109 on the clamping plate 101 can provide stable support for the target thin-walled enclosure 200 by abutting against the inner wall surface of the target thin-walled enclosure 200, which is beneficial to further improve the processing yield of the thin-walled enclosure.

[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The length of the notch 143 is at least three-quarters of the total length of the outer ring 104. According to the structure provided in this embodiment, the outer ring 104 expands more uniformly under the action of the pressure block 103, so as to form a uniform and reliable support for the target thin-walled enclosure 200.

[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 A plurality of notches 143 extend alternately to both ends of the outer ring 104 in a direction parallel to the central axis of the outer ring 104. According to the structure provided in this embodiment, the plurality of notches 143 extending alternately to both ends of the outer ring 104 can make the outer ring 104 expand and deform more uniformly, which is also beneficial to further improve the processing yield of thin-wall encapsulation.
