Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to an assembly mechanism for replacing sealing rings. Background Art

[0002] A sealing ring is a workpiece that performs a sealing function.

[0003] Common sealing ring materials include rubber. Rubber sealing rings are directly stuck on the sealing groove of the outer wall of the workpiece for use. With the long-term use of the sealing ring, the worn sealing ring needs to be replaced. When replacing, just remove the worn sealing ring and then install a new sealing ring on the sealing groove.

[0004] At present, the common installation method of the sealing ring is to expand the sealing ring through an expansion device, then insert the workpiece into the expanded sealing ring, and then shrink the sealing ring to the sealing groove position of the workpiece. However, there is no limit on the workpiece when inserting the expanded sealing ring, resulting in that each time a new workpiece is inserted into the expanded sealing ring, the staff needs to rotate the sealing ring relative to the sealing groove, thereby reducing the convenience of assembling the sealing ring.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-3 A sealing ring replacement assembly mechanism shown includes a workbench 101 and a supporting mechanism. An opening mechanism is provided in the middle of the workbench 101. The sealing ring is opened by the opening mechanism, and then the workpiece is inserted into the opened sealing ring. The opened sealing ring is then moved to the sealing groove position of the workpiece, so that the sealing ring shrinks and is stuck in the sealing groove, thereby completing the installation of the sealing ring on the workpiece.

[0022] In a preferred embodiment, a supporting mechanism is arranged inside the workbench 101, and the supporting mechanism is used to limit the workpiece. The supporting mechanism includes a supporting block 201 arranged below the opening mechanism. A first cylinder 202 is installed inside the workbench 101, and the output end of the first cylinder 202 is transmission-connected to the bottom end of the supporting block 201. After the opening mechanism opens the sealing ring, the workpiece is inserted into the opened sealing ring and against the top of the supporting block 201. Then, the first cylinder 202 drives the supporting block 201 to rise and fall. The lifting of the supporting block 201 can drive the workpiece to rise and fall until the sealing groove of the workpiece is aligned with the sealing groove of the sealing ring. At this time, the first cylinder 202 stops working, and then the opened sealing ring is retracted to the sealing groove of the workpiece. After that, when installing the sealing ring, the same batch of workpieces only need to resist the adjusted supporting block 201 to automatically align the sealing ring and the sealing groove, thereby improving the convenience of installing the sealing ring.

[0023] Among them, the expansion mechanism includes a top groove 301 opened at the top of the workbench 101, and a plurality of movable plates 302 are slidably arranged on the top of the inner wall of the workbench 101. The movable plates 302 are arranged in a fan shape, and the tops of the plurality of movable plates 302 are fixedly connected with expansion shafts 303. The bottom end of the movable plate 302 is provided with a lifting mechanism, and the sealing ring is placed on the top of the plurality of movable plates 302, and the plurality of expansion shafts 303 can be covered, and then the plurality of movable plates 302 move back to back, so that the plurality of expansion shafts 303 can move back to back, until the plurality of expansion shafts 303 expand the sealing ring, and then the workpiece can be inserted into the expanded sealing ring, and then the expanded sealing ring is moved up by the lifting mechanism until the sealing ring is separated from the expansion shaft 303, and at this time the sealing ring will automatically shrink to the sealing groove position of the workpiece.

[0024] Among them, the top ends of the multiple movable plates 302 are fixedly connected with wedge blocks 602, and the top of the inner wall of the workbench 101 is provided with multiple wedge grooves 601. The outer walls of the multiple wedge blocks 602 are slidably connected with the inner walls of the multiple wedge grooves 601 respectively. By sliding the wedge blocks 602 in the wedge grooves 601, the moving path of the movable plates 302 can be limited.

[0025] Among them, the bottom end of the inner wall of the workbench 101 is rotatably connected with 404, and the top of 404 is fixedly connected with the first rotating ring 401. The top of the first rotating ring 401 is provided with multiple arc grooves 402 in a ring array, and the inner walls of the multiple arc grooves 402 are slidably provided with connecting shafts 403. The tops of the multiple connecting shafts 403 are respectively fixedly connected to the bottom ends of the multiple movable plates 302. Through the mutual limitation of the arc grooves 402 and the connecting shafts 403, when the first rotating ring 401 rotates clockwise, and under the connection between the connecting shafts 403 and the movable plates 302, the multiple movable plates 302 move back to back, thereby allowing the spreading mechanism to work.

[0026] Among them, a servo motor 502 is installed inside the workbench 101, and a gear ring 501 is arranged on the output end of the servo motor 502. A gear sleeve 503 is fixedly sleeved on the outer wall of the first rotating ring 401. The outer wall of the servo motor 502 is meshedly connected with the outer wall of the gear sleeve 503. The servo motor 502 can drive the gear ring 501 to rotate, and the rotation of the gear ring 501 can drive the gear sleeve 503 to rotate, thereby rotating the first rotating ring 401 and enabling the spreading mechanism to work.

[0027] The lifting mechanism includes a plurality of stays 701 arranged inside the workbench 101, the stays 701 and the movable plates 302 are arranged in a staggered manner, a second cylinder 704 is installed inside the workbench 101, and a movable ring 702 is arranged at the output end of the second cylinder 704, and a plurality of fixed rods 703 are fixedly connected to the top of the movable ring 702, and the tops of the plurality of fixed rods 703 are respectively fixedly connected to the ends of the plurality of stays 701. When the plurality of movable plates 302 move back to back, a gap will appear between two adjacent movable plates 302. At this time, the second cylinder 704 works to drive the movable ring 702 to rise, and the rising of the movable ring 702 can drive the fixed rod 703 to rise, so that the support bar 701 rises, and the support bar 701 rises from between two adjacent movable plates 302, which can drive the sealing ring opened by the expansion shaft 303 to move upward until the sealing ring is separated from the expansion shaft 303, and the sealing ring can automatically shrink into the sealing groove of the workpiece. Since the multiple fixed rods 703 are arranged at intervals, they will not affect the position of the gear ring 501 inside the workbench 101.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
