Description

Technical Field

[0001] This invention belongs to the field of mechanical seal press-fitting technology, specifically relating to a press-fitting device for processing mechanical seals. Background Technology

[0002] Mechanical seals are high-precision dynamic sealing devices, mainly used to prevent fluid leakage in rotating equipment (such as pumps, compressors, and reactors) during operation. They achieve a sealing effect by having one or more pairs of end faces perpendicular to the axis of rotation (dynamic and stationary rings) keep in close contact and slide relative to each other under the action of fluid pressure and elastic force of elastic elements. During the manufacturing process, mechanical seals need to be pressed together using press-fitting equipment to ensure that the mechanical seals are precisely installed together.

[0003] During the press-fitting operation of mechanical seals, the mounting base and end cap of the mechanical seal are in a movable state before press-fitting. Moreover, the rotating ring applies an upward thrust to the end cap, making it difficult for the mounting base and end cap to align precisely during press-fitting. This can easily lead to deflection. When the mounting base and end cap deflect relative to each other, the bolt holes at the mounting point are difficult to align, which is not conducive to the subsequent tightening of multiple bolts one by one. Furthermore, the silicone sealant between the two rotating rings in the mechanical seal protrudes from the inner circumference of the mounting base and end cap. Thus, the presence of silicone sealant affects the positioning accuracy of the mechanical seal during positioning.

[0004] Therefore, a press-fitting device for processing mechanical seals is proposed. Summary of the Invention

[0005] This invention provides a press-fitting device for processing mechanical seals, the purpose of which is to solve the problems mentioned above.

[0006] This invention provides a press-fitting device for processing mechanical seals, including a base. Five support rods are evenly spaced circumferentially on the top of the base. A support platform is provided at one end of each support rod. A fixing frame is provided on the circumferential side of the top of the base near the support rods. Two electric push rods are symmetrically arranged on the top of the fixing frame. A compression ring is fixedly connected to the output end of each electric push rod. A through hole is provided at the center of the top of the support platform, and twelve adjusting grooves are evenly spaced circumferentially on the outer side of the top of the support platform near the through hole. A mechanical seal positioning assembly and a mechanical seal and shaft positioning assembly are provided on the support platform. A drive assembly is provided on the base. The mechanical seal positioning assembly includes a servo motor located at the center of the bottom of the support platform. The servo motor is fixedly connected to a driving bevel gear through its output end on one side. A ball screw is rotatably connected to the inner wall of the adjusting groove. A driven bevel gear is located at one end of the ball screw near the inside of the through hole. The driven bevel gear and the driving bevel gear mesh and drive each other. An adjusting block is fixedly connected to the screw nut seat on the ball screw by screws. The adjusting block and the adjusting groove are slidably connected. A groove is provided at the center of the top of the adjusting block. A positioning rod is movably inserted through the bottom of the groove. A conical surface is provided on the outer circumference of the positioning rod near the bottom.

[0007] Furthermore, the driving assembly includes a rotating disk that slides and rotates on the top of the base. The outer circumferential surface of the rotating disk is provided with a plurality of anti-slip grooves at equal intervals in the circumferential direction, and the top of the rotating disk is provided with twelve guide blocks at equal intervals in the circumferential direction. An inclined surface is provided on one side of the outer wall of the guide block, and a vertical surface is provided on the other side of the outer wall of the guide block. The top of the guide block is provided with an end face.

[0008] Furthermore, the mechanical seal includes a mounting base placed on top of the support platform. The bottom of the mounting base has a through lower mounting hole, and the top of the mounting base is fixedly connected to an end cap by bolts. The top of the end cap has a recessed hole, and the bottom of the end cap has an upper mounting hole located directly below the recessed hole. Static rings are installed on the inner bottom of the mounting base and the inner top of the end cap, and two dynamic rings are provided between the mounting base and the end cap. Clamping silicone is provided between the two dynamic rings.

[0009] Furthermore, the axial positioning assembly includes a fixed column located at the center of the top of the support platform. A cylinder is fixedly connected to the center of the top of the fixed column by bolts. A storage groove is formed on the outer circumference of the fixed column. A cavity is formed at the center of the interior of the fixed column. A connecting groove is formed in the interior of the fixed column near the cavity and the storage groove. A vertical wedge is fixedly connected to the cylinder through its output end on one side. A wedge surface one is formed on the outer wall of the vertical wedge near the bottom. A horizontal wedge slides movably inside the storage groove. A wedge surface two is formed on the outer wall of the horizontal wedge facing the vertical wedge. A top plate is provided on the other outer wall of the horizontal wedge.

[0010] Furthermore, a recessed cavity is provided at the center of the outer wall of the top platform on the side away from the horizontal wedge. A limiting plate is provided on the inner wall of the recessed cavity, and a movable piece is movably inserted through the outer wall of the limiting plate. A spring is provided between one side wall of the movable piece and one side inner wall of the recessed cavity.

[0011] Furthermore, the axes of the through hole, the driving bevel gear, the fixed column, and the extrusion ring are all on the same vertical axis; By adopting the above technical solution, and utilizing the same vertical axis, the twelve positioning rods can move synchronously under the meshing transmission of the driving bevel gear and the driven bevel gear. The twelve positioning rods are used to position the mechanical seal. Under the guidance of the vertical wedge and the horizontal wedge, multiple horizontal wedges can move synchronously to position the mechanical seal.

[0012] Furthermore, the positioning rod movably passes through the lower mounting hole and the upper mounting hole, and the bottom end of the positioning rod abuts against the end face. The bottom of the mounting base is provided with a slot for storing nuts at a position directly below the lower mounting hole. By adopting the above technical solution, the relative positions of the mounting base and the end cap can be positioned by using the positioning rods passing through the lower and upper mounting holes. With the cooperation of multiple positioning rods, the mounting base and the end cap can be positioned, preventing the mounting base and the end cap from deflecting during tightening. This ensures that the bolts can quickly pass through the mounting base and the end cap for tightening. Furthermore, the grooves and recesses not only limit and store the nuts but also store the screw heads.

[0013] Furthermore, the first wedge and the second wedge are parallel and in contact with each other; By adopting the above technical solution, and utilizing parallel wedge surfaces one and two, it is made to have tilting guiding ability. When the vertical wedge moves vertically downward, the vertical wedge can push the horizontal wedge to move horizontally.

[0014] Furthermore, one end of the movable piece does not protrude from the outer wall of the ejector plate when the spring is not under force; By adopting the above technical solution, the protruding setting of the movable plate is avoided from affecting the placement of the mechanical seal, ensuring that the mechanical seal can be placed on the top of the support platform after being sleeved on the outside of the fixed column.

[0015] The beneficial effects of this invention are as follows: 1. This invention adjusts the circumferential position of the positioning rods according to the location of the bolt mounting holes on the mechanical seal to achieve a fit. The positioning rods are used to position the mounting base and end cap before press-fitting, ensuring that the mounting base and end cap are accurately aligned, which facilitates subsequent fastening after press-fitting. By simultaneously disengaging multiple positioning rods from the mechanical seal, not only is space provided for bolt tightening, but the tightening operation is also facilitated, improving the efficiency of the press-fitting operation.

[0016] 2. This invention achieves axial positioning by using the top plate and the movable plate in cooperation. The top plate applies pressure to the inner circumferential surface of the mechanical seal to achieve axial positioning, while the movable plate makes relative displacement after contacting the clamp silicone in the mechanical seal. This achieves auxiliary positioning while avoiding interference from the protruding clamp silicone with the positioning of the mechanical seal. It also avoids damage to the clamp silicone due to excessive pressure during positioning, thus ensuring the integrity of the sealing structure of the mechanical seal.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Reference Figure 1-6 This invention provides a press-fitting device for processing mechanical seals, comprising a base 1, five support rods 11 evenly spaced in the circumferential direction on the top of the base 1, a support platform 2 at one end of each support rod 11, a fixing frame 12 on the circumferential side of the top of the base 1 near the support rods 11, two electric push rods 121 symmetrically arranged on the top of the fixing frame 12, and a compression ring 122 fixedly connected to the output end of each electric push rod 121. A through hole 21 is provided at the center of the top of the support platform 2, and twelve adjusting grooves 22 are evenly spaced in the circumferential direction on the outer side of the top of the support platform 2 near the through hole 21. A mechanical seal positioning assembly 3, a mechanical seal 4, and a shaft positioning assembly 6 are provided on the support platform 2, and a drive assembly 5 is provided on the base 1. The mechanical seal positioning assembly 3 includes a servo motor located at the center of the bottom of the support platform 2. The servo motor is fixedly connected to a drive bevel gear 31 through its output end on one side. A ball screw 32 is rotatably connected to the inner wall of the adjustment groove 22. A driven bevel gear 321 is provided at one end of the ball screw 32 near the inside of the through hole 21. The driven bevel gear 321 and the drive bevel gear 31 mesh and drive each other. An adjustment block 33 is fixedly connected to the screw nut seat on the ball screw 32 by screws. The adjustment block 33 and the adjustment groove 22 are slidably connected. The sliding connection ensures the stability of the linear movement of the adjustment block 33 inside the adjustment groove 22, thereby realizing the adjustment of the position of the adjustment block 33 and the positioning rod 34. The positioning rod 34 is adjusted to be directly below the bolt installation position of the mechanical seal 4. A groove 331 is provided at the center of the top of the adjustment block 33. The positioning rod 34 is movably passed through the bottom of the groove 331. A conical surface 341 is provided on the outer circumference of the positioning rod 34 near the bottom. The drive assembly 5 includes a rotating disk 51 that slides and rotates on the top of the base 1. Several anti-slip grooves 511 are evenly spaced on the outer circumferential surface of the rotating disk 51. Twelve guide blocks 52 are evenly spaced on the top of the rotating disk 51. An inclined surface 521 is provided on one side of the outer wall of the guide block 52. A vertical surface 522 is provided on the other side of the outer wall of the guide block 52. An end face 523 is provided on the top of the guide block 52. The mechanical seal 4 includes a mounting base 41 placed on top of the support platform 2. The bottom of the mounting base 41 has a through lower mounting hole 411. A positioning rod 34 movably passes through the lower mounting hole 411 and the upper mounting hole 422, with the bottom end of the positioning rod 34 abutting against the end face 523. A slot for storing a nut is provided at the bottom of the mounting base 41 near the lower mounting hole 411. By using the positioning rod 34 passing through the lower mounting hole 411 and the upper mounting hole 422, the relative positions of the mounting base 41 and the end cap 42 can be positioned. With the cooperation of multiple positioning rods 34, the mounting base 41 and the end cap 42 are positioned, preventing the mounting base 41 and the end cap 42 from aligning. During tightening, deflection occurs, ensuring that the bolt can quickly pass through the mounting base 41 and end cap 42 for tightening. The groove and recess 421 not only limit and store the nut but also store the screw head. The top of the mounting base 41 is fixedly connected to the end cap 42 by bolts. The top of the end cap 42 has a recess 421, and the bottom of the end cap 42 has an upper mounting hole 422 located directly below the recess 421. The bottom of the mounting base 41 and the top of the end cap 42 are both equipped with stationary rings 45, and two moving rings 43 are provided between the mounting base 41 and the end cap 42. A clamping silicone 44 is provided between the two moving rings 43. To ensure precise press-fitting of the mounting base 41 and end cap 42 in the mechanical seal 4, in this embodiment, the positioning rod 34 is adjusted circumferentially according to the position of the bolt mounting holes on the mechanical seal 4 to achieve a fit. The positioning rod 34 positions the mounting base 41 and end cap 42 before press-fitting, ensuring precise alignment and facilitating subsequent tightening. The simultaneous disengagement of multiple positioning rods 34 from the mechanical seal 4 not only provides space for bolt tightening but also facilitates the tightening operation, improving press-fitting efficiency. Specifically, the mounting base 41 and end cap 42 are first positioned according to the lower mounting hole 411 on the mounting base 41 and the end cap 42... The position of the adjusting block 33 is adjusted by adjusting the position of the upper mounting hole 422 so that the positioning rod 34 passing through the adjusting block 33 can pass through the lower mounting hole 411 and the upper mounting hole 422. This controls the operation of the servo motor at the bottom of the support platform 2. The servo motor drives the active bevel gear 31 to rotate through its output end on one side. Under the meshing transmission of the active bevel gear 31 and the driven bevel gear 321, the active bevel gear 31 pulls the twelve driven bevel gears 321 to rotate. The driven bevel gears 321 pull the ball screw 32 to rotate. The ball screw 32 pulls the adjusting block 33 to move within the adjusting groove 22, thereby adjusting the position of the adjusting block 33. Then, the nut for the bolt is embedded in the hexagonal groove on the top of the adjusting block 33. Inside 331, the mounting base 41 with the stationary ring 45 fixed is placed on top of the support platform 2. During placement, the lower mounting hole 411 of the mounting base 41 is fitted onto the positioning rod 34, and the moving ring 43 is placed inside the mounting base 41. Subsequently, the end cap 42 with the stationary ring 45 fixed is placed on top of the moving ring 43. During placement, the upper mounting hole 422 on the end cap 42 is fitted onto the positioning rod 34. Under the positioning and guidance of the positioning rod 34, the mounting base 41 and the end cap 42 are positioned. During the final pressing, the electric push rod 121 is controlled to drive the compression ring 122 downward through its output end. After the compression ring 122 contacts and applies pressure to the end cap 42, the end cap 42... 2. Press the moving ring 43 and connect it with the mounting base 41. At this time, rotate the rotating disk 51. The guide block 52 on the rotating disk 51 moves circumferentially in sync. As the position of the guide block 52 changes, the end face 523 of the top of the guide block 52 separates from the bottom end of the positioning rod 34. After the positioning rod 34 loses its support, it moves vertically downward under the action of gravity. The positioning rod 34 separates from the lower mounting hole 411 and the upper mounting hole 422. The screw in the bolt passes through the upper mounting hole 422 and the lower mounting hole 411 in sequence. After the screw contacts the nut, rotate the screw. One end of the screw is screwed into the nut until the screw head is screwed into the concave hole 421. The mounting base 41 and the end cover 42 are press-fitted and fixed by the bolt.

[0021] Example 2 Reference Figure 1 , Figure 7-9Based on the above embodiments, this invention also proposes a shaft positioning assembly 6. The shaft positioning assembly 6 includes a fixed column 61 located at the center of the top of the support platform 2. The shafts of the through hole 21, the driving bevel gear 31, the fixed column 61, and the compression ring 122 are all on the same vertical axis. By utilizing the setting of the same vertical axis, under the meshing transmission of the driving bevel gear 31 and the driven bevel gear 321, the twelve positioning rods 34 can move synchronously. The twelve positioning rods 34 are used to position the mechanical seal 4 and are guided by the vertical wedge 62 and the horizontal wedge 63. The mechanical seal 4 is positioned by multiple horizontal wedges 63 moving synchronously. A cylinder 611 is bolted to the center of the top of the fixing column 61. A receiving groove 612 is formed on the outer circumference of the fixing column 61, and a cavity 613 is formed at the center of the interior of the fixing column 61. A connecting groove 614 is formed inside the fixing column 61 near the cavity 613 and the receiving groove 612. A vertical wedge 62 is fixedly connected to the cylinder 611 via its output end. A vertical wedge 62 is formed on the outer wall of the vertical wedge 62 near the bottom. The storage groove 612 has a first wedge surface 621, and a horizontal wedge platform 63 is movably slidable inside it. A second wedge surface 631 is formed on the outer wall of the horizontal wedge platform 63 facing the vertical wedge platform 62. The first wedge surface 621 and the second wedge surface 631 are parallel and in abutting state. The parallel wedge surface 621 and the second wedge surface 631 provide tilting guidance capability. When the vertical wedge platform 62 moves vertically downward, it can push the horizontal wedge platform 63 to move horizontally. A top plate 64 is provided on the other outer wall of the horizontal wedge platform 63. The outer wall of the top plate 64 away from the horizontal wedge platform 63 is... A recessed cavity 641 is provided at the central position. A limiting plate 6411 is provided on the inner side wall of the recessed cavity 641. A movable piece 6412 is movably passed through the outer side wall of the limiting plate 6411. A spring 6413 is provided between one side wall of the movable piece 6412 and one side inner wall of the recessed cavity 641. When the spring 6413 is not under force, one side end of the movable piece 6412 does not protrude from the outer side wall of the ejector plate 64, so as to avoid the protrusion of the movable piece 6412 affecting the placement of the mechanical seal 4 and ensuring that the mechanical seal 4 can be placed on the top of the support platform 2 after being sleeved on the outside of the fixed column 61. To achieve axial positioning of the mechanical seal 4, in this embodiment, the ejector plate 64 and the movable plate 6412 cooperate with each other. While the ejector plate 64 applies pressure to the inner circumferential surface of the mechanical seal 4 to achieve axial positioning, the movable plate 6412 contacts the clamp silicone 44 in the mechanical seal 4, causing relative displacement. This achieves auxiliary positioning while preventing the protruding clamp silicone 44 from interfering with the positioning of the mechanical seal 4, and also preventing the clamp silicone 44 from being damaged due to excessive pressure during positioning, thus ensuring the integrity of the sealing structure of the mechanical seal 4. Specifically, when the mounting base 41, the rotating ring 43, and the end cover 42 are placed sequentially above the support platform 2, the mounting base 41 and the end cover 42 are in a positioned state, and the rotating ring 43 is in a movable state inside the mounting base 41 and the end cover 42. At this time, the stroke of the output end of the control cylinder 611 is adjusted according to the inner radius of the mechanical seal 4 to ensure that multiple ejector plates 6412... 4 can simultaneously contact the inner circumferential surface of the mechanical seal 4. Then, the control cylinder 611 drives the vertical wedge 62 to move downward through its output end on one side. Using the parallel wedge surface 621 and wedge surface 631, it has tilting guidance capability. When the vertical wedge 62 moves vertically downward, the vertical wedge 62 can push the horizontal wedge 63 to move horizontally. The horizontal wedge 63 pulls the ejector plate 64 out. After the ejector plate 64 contacts the moving ring 43, it pushes it to move between the mounting base 41 and the end cover 42, ensuring that the mounting base 41 and the end cover 42 are on the same vertical axis as the moving ring 43. The movable piece 6412 contacts the clamp silicone 44 between the two moving rings 43. Under the pressure of the clamp silicone 44, the movable piece 6412 moves towards the inside of the cavity 641. The spring 6413 is compressed by force to avoid the clamp silicone 44 being damaged due to excessive pressure during positioning, thus ensuring the integrity of the sealing structure of the mechanical seal 4.
