Description

Technical Field

[0001] This utility model relates to the field of clamping mechanism technology, specifically a clamping mechanism for a mechanical seal assembly machine. Background Technology

[0002] A mechanical seal is a device that prevents fluid leakage by having at least one pair of end faces perpendicular to the axis of rotation kept in contact and sliding relative to each other under the action of fluid pressure, the elastic force of the compensation mechanism, and the cooperation of auxiliary seals. It requires uniform force, no skew, and no surface damage during the pressing process. After the mechanical seal is assembled, a pressing mechanism is often used to press the mechanical seal tightly to prevent the connection from loosening.

[0003] Current clamping mechanisms use multiple cylinders or independent drive sources, which are prone to asynchronous action due to differences in response time. This can cause uneven force on the seal, resulting in tilting or jamming. Furthermore, the pressure head material is hard and can easily cause scratches, indentations, or even cracks when it comes into direct contact with ceramic, silicon carbide, or rubber sealing surfaces, seriously affecting the sealing performance. Therefore, we propose a clamping mechanism for mechanical seal assembly machines. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a pressing mechanism for a mechanical seal assembly machine, comprising a support frame, a worktable fixedly connected to the upper end of the support frame, mounting brackets fixedly connected to the upper ends of both sides of the support frame, sliding grooves equally spaced around the surface of the worktable, sliding seats slidably connected inside each of the four sliding grooves, bases fixedly connected to the bottom of each of the four sliding seats, and push rods rotatably connected to the lower ends of each of the four bases, a geared motor fixedly embedded inside the support frame, and a threaded rod driven through a coupling at the output end of the geared motor.

[0006] As a preferred embodiment of this utility model, the outer circumference of the threaded rod is threadedly connected to a threaded block, and rotating blocks are fixedly connected to the outer periphery of the threaded block, with one side of the rotating block being rotatably connected to the push rod.

[0007] As a preferred embodiment of this utility model, the bottom of the workbench is fixedly connected to two limiting posts, and both sides of the outer periphery of the threaded block are fixedly connected to fixing ears, and the interior of the fixing ears is slidably connected to the limiting posts.

[0008] As a preferred technical solution of this utility model, a sliding column is slidably connected to one side surface of the slide block through a through groove, and a buffer seat is fixedly connected to one end of the four sliding columns. A pad is provided on one side of the buffer seat.

[0009] As a preferred embodiment of this utility model, the other ends of the four sliding columns are all fixedly connected to limit rings, and dampers are fixedly installed at both ends of one side of the slide block. One end of the damper is fixedly connected to the buffer seat, and a buffer spring is sleeved on the outer periphery of the damper.

[0010] As a preferred technical solution of this utility model, the top of the mounting bracket is provided with a square groove, and a servo motor is fixedly installed on the upper side of one side of the mounting bracket. The output end of the servo motor is connected to a bidirectional lead screw through the square groove via a coupling.

[0011] As a preferred embodiment of this utility model, both ends of the bidirectional lead screw are threaded with movable seats, the lower ends of the two movable seats are rotatably connected with connecting rods, and the bottoms of the two connecting rods are rotatably connected with pressure plates.

[0012] The beneficial effects of this utility model are:

[0013] 1. The clamping mechanism of this mechanical seal assembly machine drives a single threaded rod to move the threaded block linearly through a geared motor, and then moves through four push rods to synchronously push the four slide blocks radially, ensuring that the four clamping points move at the same height, and avoiding the seal from being skewed or stuck due to uneven force.

[0014] 2. The clamping mechanism of this mechanical seal assembly machine has a buffer seat connected to the damper and buffer spring through a sliding column. During the pressing process, it can absorb impact energy and achieve "soft contact and constant force pressing", which effectively prevents scratches or cracks on the surface of brittle or elastic seals such as ceramics and rubber.

[0015] 3. This mechanical seal assembly machine's clamping mechanism integrates radial clamping and axial pressing functions. It can first achieve circumferential clamping and positioning through the slide block, and then perform axial pressing by the pressure plate, ensuring a stable and controllable assembly process and improving the yield rate. This utility model has a simple and reasonable structure, novel design, and simple and convenient operation, and has high practical value. Attached Figure Description

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figures 1-5 As shown, the present invention discloses a pressing mechanism for a mechanical seal assembly machine, comprising a support frame 1, a worktable 2 fixedly connected to the upper end of the support frame 1, mounting brackets 3 fixedly connected to the upper ends of both sides of the support frame 1, sliding grooves 4 being formed at equal angles around the surface of the worktable 2, sliding seats 5 being slidably connected inside the four sliding grooves 4, bases 6 being fixedly connected to the bottom of the four sliding seats 5, and push rods 7 being rotatably connected to the lower ends of the four bases 6, a geared motor 8 being fixedly embedded inside the support frame 1, and a threaded rod 9 being driven through a coupling at the output end of the geared motor 8.

[0025] Among them, the threaded rod 9 is threadedly connected to the outer circumference of the threaded block 10, and the outer circumference of the threaded block 10 is fixedly connected to the rotating block 11. One side of the rotating block 11 is rotatably connected to the push rod 7. The linear motion of the threaded block 10 is converted into the synchronous swing of the four push rods 7 through the rotating block 11, so as to realize the equidistant radial movement of the four slide blocks 5 and ensure the uniform distribution of clamping force.

[0026] The bottom of the workbench 2 is fixedly connected to two limiting posts 12, and the outer sides of the threaded block 10 are fixedly connected to fixed ears 13. The inside of the fixed ears 13 is slidably connected to the limiting posts 12. Through the sliding cooperation between the limiting posts 12 and the fixed ears 13, the rotational freedom of the threaded block 10 is restricted, so that it can only move along the axial direction, thus ensuring transmission accuracy and mechanism stability.

[0027] Among them, a sliding column 14 is slidably connected to one side surface of the slide block 5 through a through groove. One end of the four sliding columns 14 is fixedly connected to a buffer seat 15. A pad is provided on one side of the buffer seat 15. The buffer seat 15 is guided to move linearly along the axial direction by the cooperation of the sliding column 14 and the through groove, so as to ensure that the force direction is perpendicular during the pressing process and avoid damage to the seal by uneven load.

[0028] Among them, the other end of each of the four sliding columns 14 is fixedly connected to a limit ring 16, and a damper 17 is fixedly installed at both ends of one side of the slide block 5. One end of the damper 17 is fixedly connected to the buffer seat 15. A buffer spring 18 is sleeved on the outer periphery of the damper 17. Through the synergistic action of the buffer spring 18 and the damper 17, elastic buffering is provided during the pressing process to absorb impact energy and achieve "soft pressing", effectively protecting the sealing surface from being scratched or cracked.

[0029] The mounting bracket 3 has a square slot 19 on its top. A servo motor 20 is fixedly installed on the upper side of one side of the mounting bracket 3. The output end of the servo motor 20 is connected to a bidirectional lead screw 21 through a coupling passing through the square slot 19. The servo motor 20 drives the moving seats 22 on both sides to move synchronously through the bidirectional lead screw 21, so as to realize the precise lifting and lowering control of the pressure plate 24 and meet the pressing requirements of workpieces of different heights.

[0030] The two ends of the bidirectional lead screw 21 are threaded with movable seats 22. The lower ends of the two movable seats 22 are rotatably connected with connecting rods 23. The bottom of the two connecting rods 23 is rotatably connected with pressure plates 24. The horizontal movement of the movable seats 22 is converted into the vertical movement of the pressure plates 24 through the connecting rods 23, so as to realize the axial pressing action. The structure is simple and the transmission efficiency is high.

[0031] Working Principle: During use, the mechanical seal to be assembled is placed in the center of the worktable 2. The geared motor 8 is started, its output driving the threaded rod 9 to rotate. The threaded block 10 moves axially under the action of the threaded transmission, and the four rotating blocks 11 on its outer side push the four push rods 7 to swing synchronously, causing the four slide blocks 5 to slide simultaneously along the slide groove 4, so that the four buffer seats 15 clamp the outer edge of the seal, achieving automatic centering and positioning. After clamping, the servo motor 20 is started, its output driving the bidirectional lead screw 21 to rotate. The two moving seats 22 move synchronously downwards under the action of the thread, driving the pressure plate 24 to slide vertically downwards through the connecting rod 23, applying axial pressure to the seal. During the pressing process, the buffer seats 15 provide flexible support under the action of the damper 17 and the buffer spring 18, absorbing impact force and preventing workpiece damage. After pressing into place, the servo motor 20 reverses, and the pressure plate 24 rises; the geared motor 8 reverses, the threaded block 10 moves in the opposite direction, and the push rods 7 drive the slide blocks 5 to slide outwards, releasing the clamp, removing the finished product, and completing one work cycle.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
