A pump body mechanical seal polishing apparatus

Abstract

This utility model relates to the field of polishing equipment technology, and discloses a polishing device for a pump body mechanical seal, comprising: a polishing assembly, the polishing assembly including a worktable, a mounting platform fixedly installed on the top of the worktable, and a mounting plate fixedly installed on the top of the worktable. A drive gear is movably connected to the inner side of the mounting plate via a rotating shaft, and driven gears are meshed around the drive gear. This pump body mechanical seal polishing device uses the output end of a first motor to drive the drive gear to rotate. Simultaneously, the drive gear, through the action of its surface teeth, drives the driven gear to rotate. While the driven gear rotates, its teeth mesh with the inner side of the mounting plate, causing the driven gear to perform a circular motion around the inner ring of the mounting plate. This circular motion causes the bottom of the polishing groove to rub against the polishing layer, polishing the seal. Multiple seals can be polished simultaneously, increasing polishing efficiency.

Description

Technical Field

[0001] This utility model relates to a pump body mechanical seal polishing device, belonging to the technical field of polishing equipment. Background Technology

[0002] The background technology of pump body mechanical seal polishing equipment involves the precision machining and surface treatment of pump body mechanical seal components. Pump body mechanical seals are key components used to prevent liquid leakage within the pump, and their performance directly affects the pump's operating efficiency and service life. To ensure a sealing effect, the contact surfaces of the mechanical seal must have extremely high smoothness and precision, requiring treatment of the sealing surface through precision polishing techniques. With the development of pump technology, the requirements for the surface smoothness and precision of sealing components are constantly increasing. Traditional manual polishing methods can no longer meet the needs of modern high-efficiency pump systems; therefore, specialized mechanical seal polishing equipment has been developed.

[0003] Authorization announcement number (CN217992100U) discloses a sealing ring polishing device, including: an operating platform, a slider, a first connecting rod, a second connecting rod, a telescopic motor, a cylinder, a drive motor, and a polishing disc. Before polishing the sealing ring, the sealing ring can be placed between two or more arc-shaped plates. The telescopic motor drives the arc-shaped plates to move, thereby adjusting the distance between the arc-shaped plates, so that the arc-shaped plates and the sealing ring are tightly fitted and fixed. Only the forward and reverse rotation of the telescopic motor needs to be adjusted to flexibly adapt to sealing rings of various sizes. It has high flexibility, is easy to operate, and has good application prospects and applicable scope.

[0004] In summary, the aforementioned seal polishing equipment suffers from the drawback of not being able to polish multiple seals simultaneously. Because these devices are generally designed for single-workpiece polishing, only one seal can be processed at a time, resulting in low production efficiency, especially in mass production, leading to significant time waste and increased workload. Furthermore, the equipment can only polish one side of the seal, preventing the simultaneous processing of both ends in the same step, thus limiting processing flexibility and efficiency.

[0005] To address this, a pump body mechanical seal polishing device is proposed. Utility Model Content

[0006] In view of this, the present invention provides a pump body mechanical seal polishing device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is achieved as follows: a pump body mechanical seal polishing device, comprising:

[0008] A polishing assembly includes a worktable, a mounting platform fixedly mounted on the top of the worktable, and a mounting plate fixedly mounted on the top of the worktable. A drive gear is movably connected to the inner side of the mounting plate via a rotating shaft. Driven gears are meshed around the drive gear, and the driven gears mesh with the teeth on the inner side of the mounting plate.

[0009] The lifting assembly includes a housing, which is fixedly installed on the top of the inner side of the mounting platform. A bidirectional threaded rod is movably connected to the inner side of the housing via a rotating shaft, and threaded sleeves are engaged on both the left and right sides of the surface of the bidirectional threaded rod.

[0010] More preferably, the driven gear has polishing grooves on its surface, and there are four polishing grooves, which are equidistantly distributed on the surface of the driven gear.

[0011] More preferably, a fixed block is movably connected to the top of the drive gear via a bearing, and a first motor is fixedly mounted on the top of the fixed block, with the output end of the first motor fixedly connected to the drive gear.

[0012] More preferably, the bottom of the workbench is fixedly equipped with a support base, and the number of support bases is four, which are equally distributed around the bottom of the workbench.

[0013] More preferably, a connecting rod is movably connected to the bottom of the threaded sleeve, a support block is movably connected to the bottom of the connecting rod, a cover plate is fixedly installed on the bottom of the support block, and a polishing layer is provided on the bottom of the inner side of the mounting plate and the bottom of the cover plate.

[0014] More preferably, the surface of the cover plate is provided with a through groove, and the outer side of the cover plate fits into the inner side of the mounting plate.

[0015] More preferably, a second motor is fixedly installed on the right side of the mounting platform, and the output end of the second motor is fixedly connected to a bidirectional threaded rod.

[0016] More preferably, a limiting groove is formed on the top of the outer shell, and a limiting block is fixedly installed on the top of the threaded sleeve, with the limiting block slidably connected to the inner side of the limiting groove.

[0017] The present invention has the following advantages due to the adoption of the above technical solution:

[0018] I. This utility model drives the active gear to rotate through the output end of the first motor. While the active gear rotates, it drives the driven gear to rotate through the action of the surface teeth. While the driven gear rotates, the teeth mesh with the inner side of the mounting plate, so that the driven gear makes a circular motion around the inner ring of the mounting plate. While the driven gear makes a circular motion, the bottom of the polishing groove rubs against the polishing layer to polish the seal. Multiple seals can be polished, increasing polishing efficiency.

[0019] II. This utility model starts the second motor, and the output end of the second motor drives the bidirectional threaded rod to rotate. While the bidirectional threaded rod rotates, the surface threads drive the threaded sleeves on both sides of the surface to move inward. As the threaded sleeves move inward, the bottom connecting rod is movably connected to the support block, which drives the bottom cover plate to move up and down. This allows the polished layer on the top of the cover plate to be polished with the other side of the seal. The threaded sleeves are limited by the limiting block slidingly connected to the inside of the limiting groove, so as to prevent them from deviating during the movement.

[0020] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0031] Example 1

[0032] like Figure 1-6 As shown, this utility model embodiment provides a pump body mechanical seal polishing device, including:

[0033] Polishing assembly 100 includes a worktable 101, a mounting platform 103 fixedly mounted on the top of the worktable 101, and a mounting plate 104 fixedly mounted on the top of the worktable 101. A drive gear 105 is movably connected to the inner side of the mounting plate 104 via a rotating shaft. Driven gears 106 are meshed around the drive gear 105, and the driven gears 106 mesh with the teeth on the inner side of the mounting plate 104. Lifting assembly 200 includes a housing 201 fixedly mounted on the top of the inner side of the mounting platform 103. A bidirectional threaded rod 202 is movably connected to the inner side of the housing 201 via a rotating shaft. The bidirectional threaded rod 202 has two sides on its surface. The mounting plate 104 and the bottom of the cover plate 206 are both meshed with threaded sleeves 203. The bottom of the threaded sleeves 203 is movably connected to a connecting rod 204. The bottom of the connecting rod 204 is movably connected to a support block 205. The bottom of the support block 205 is fixedly installed with a cover plate 206. The bottom of the inner side of the mounting plate 104 and the bottom of the cover plate 206 are both provided with polishing layers 110. When the bidirectional threaded rod 202 rotates, the threaded sleeves 203 on both sides of the surface are driven to move inward through the action of the surface threads. When the threaded sleeves 203 move inward, the bottom cover plate 206 moves up and down through the bottom connecting rod 204 and the support block 205, so that the polishing layer 110 on the top of the cover plate 206 can be polished with the other side of the seal.

[0034] In this embodiment, preferably, the driven gear 106 has four polishing grooves 107 on its surface, which are equidistantly distributed on the surface of the driven gear 106. The polishing grooves 107 can be used to engage the seal with the inside of the polishing grooves 107 for polishing.

[0035] In this embodiment, preferably, the top of the drive gear 105 is movably connected to the fixing block 108 via a bearing, and the top of the fixing block 108 is fixedly mounted with a first motor 109. The output end of the first motor 109 is fixedly connected to the drive gear 105, and the output end of the first motor 109 drives the drive gear 105 to rotate, so that it can perform subsequent grinding operations.

[0036] In this embodiment, preferably, a support base 102 is fixedly installed on the bottom of the workbench 101, and there are four support bases 102, which are evenly distributed around the bottom of the workbench 101. The workbench 101 is supported and fixed by the support bases 102.

[0037] In this embodiment, preferably, the bottom of the threaded sleeve 203 is movably connected to a connecting rod 204, the bottom of the connecting rod 204 is movably connected to a support block 205, and the bottom of the support block 205 is fixedly installed with a cover plate 206. The bottom of the inner side of the mounting plate 104 and the bottom of the cover plate 206 are both provided with a polishing layer 110. The polishing layer 110 is attached to the surface of the seal so that it can be polished during the movement.

[0038] In this embodiment, preferably, the surface of the cover plate 206 is provided with a through groove 207, and the outer side of the cover plate 206 fits with the inner side of the mounting plate 104. The mating allows the polishing layer 110 to polish the seal.

[0039] In this embodiment, preferably, a second motor 210 is fixedly installed on the right side of the mounting platform 103. The output end of the second motor 210 is fixedly connected to the bidirectional threaded rod 202. The output end of the second motor 210 drives the bidirectional threaded rod 202 to rotate, so that the cover plate 206 is raised and lowered and fits against the inner side of the mounting plate 104.

[0040] In this embodiment, preferably, a limiting groove 208 is formed on the top of the outer shell 201, and a limiting block 209 is fixedly installed on the top of the threaded sleeve 203. The limiting block 209 is slidably connected to the inner side of the limiting groove 208. The threaded sleeve 203 is limited by the limiting block 209 being slidably connected to the inner side of the limiting groove 208, so as to prevent it from shifting during movement.

[0041] In operation, this invention works as follows: First, by starting the first motor 109, the output end of the first motor 109 drives the driving gear 105 to rotate. Simultaneously, the driving gear 105, through the action of its surface teeth, drives the driven gear 106 to rotate. As the driven gear 106 rotates, its teeth mesh with the inner side of the mounting plate 104, causing the driven gear 106 to perform a circular motion around the inner ring of the mounting plate 104. This circular motion of the driven gear 106 causes the bottom of the polishing groove 107 to rub against the polishing layer 110, polishing the seals. Multiple seals can be polished simultaneously, increasing polishing efficiency. The second motor 210 is started, and the output end of the second motor 210 drives the bidirectional threaded rod 202 to rotate. As the bidirectional threaded rod 202 rotates, the threaded sleeves 203 on both sides of the surface move inward through the action of the surface threads. While the threaded sleeves 203 move inward, they are movably connected to the support block 205 through the bottom connecting rod 204, which drives the bottom cover plate 206 to move up and down. This allows the polishing layer 110 on the top of the cover plate 206 to be polished with the other side of the seal. Finally, the threaded sleeve 203 is limited by the limiting block 209 slidingly connected to the inside of the limiting groove 208 to prevent it from shifting during the movement.

[0042] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
