Description

Technical Field

[0001] The utility model relates to a press-fit assembly device, in particular to a press-fit assembly device for a rubber sealing element which is easy to position. Background Art

[0002] Because rubber materials have strong plasticity and good sealing properties, they are widely used in the production of seals. The finished rubber seals need to be assembled to the specified parts. This process requires the use of a special rubber seal pressing assembly device.

[0003] For example, the Chinese patent publication number CN216180180U discloses a rubber seal pressing assembly device that is easy to position, comprising a support base, a seal pressing base fixedly mounted on the support table of the support base, an adjustment disk provided inside the seal pressing base, a flat thread provided on the upper surface of the adjustment disk, and a plurality of adjustment toggle blocks threadedly connected to the upper surface of the adjustment disk. This rubber seal pressing assembly device that is easy to position can use an AC motor to drive the adjustment disk to rotate. Since the adjustment toggle blocks are threadedly connected to the upper end surface of the adjustment disk, the rotation of the adjustment disk can cause the plurality of adjustment toggle blocks to move inward or outward synchronously, thereby driving the positioning toggle rod to move. At this time, the moving positioning toggle rod can effectively align the rubber seal with the assembly part. This operation is performed automatically, effectively improving the working efficiency of the pressing operation.

[0004] Some problems were found during the use of the above-mentioned existing rubber seal pressing and assembly device that is easy to position. First, a positioning toggle rod is used to limit the alignment of the rubber seal and the workpiece. The rubber seal and the workpiece need to have the same diameter, but the diameter of the rubber seal is often smaller than the workpiece, resulting in the positioning toggle rod being unable to effectively position the rubber seal.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5The utility model provides a technical solution: a rubber seal pressing assembly device that is easy to position, including a base 1, a T-shaped slide groove 102 is provided on the base 1, and a positioning mechanism 5 is slidably installed in the T-shaped slide groove 102, the positioning mechanism 5 includes a positioning rod 501 and a second positioning piece 502, the lower end of the positioning rod 501 is fixedly connected to a T-shaped slider 506, and the T-shaped slider 506 slides with the T-shaped slide groove 102. The positioning mechanism 5 has a mounting hole 503 provided in the positioning mechanism 5, and an adjusting rod 507 is slidably installed in the mounting hole 503. One end of the adjusting rod 507 is fixedly connected to a dovetail slider 510, and a dovetail slide groove 512 is provided behind the second positioning piece 502. The dovetail slide groove 512 slides with the dovetail slider 510.

[0024] In this embodiment, the adjusting rod 507 is slidably matched with the T-shaped slide groove 102, so that the positioning mechanism 5 can slide on the base 1, and the workpiece is placed on the lower pressing plate 2. The spacing between the positioning mechanisms 5 can be adjusted, and the workpiece is positioned using the four positioning rods 501. The rubber seal is placed on the workpiece for preliminary alignment, and the adjusting rod 507 is slidably installed inside the mounting hole 503. Moving the adjusting rod 507 can drive the second positioning piece 502 to extend, and then the second positioning piece 502 can be used to resist the rubber seal, and then the rubber seal is positioned so that the rubber seal is aligned with the workpiece. Starting the pressing hydraulic rod 104 can drive the upper pressing plate 105 to move downward. The upper pressing plate 105 moves downward to press the rubber seal onto the workpiece. The rubber seal is positioned using the extended second positioning piece 502 to avoid the problem of different diameters of the rubber seal and the workpiece.

[0025] Among them, in order to achieve the purpose of simultaneously driving the positioning mechanism 5 to move, this device adopts the following technical solutions: a support foot 101 is fixedly connected to the bottom of the base 1 near the four corner edges, and connecting legs 201 are fixedly connected on both sides of the lower pressure plate 2. The bottom of the connecting leg 201 is fixed to the base 1, and a limiting slide groove 3 is provided in the lower pressure plate 2 and the upper pressure plate 105. The limiting slide groove 3 cooperates with the positioning mechanism 5. An adjusting motor 402 is fixedly connected to the bottom of the base 1, and a rotating disk 4 is fixedly connected to the output end of the adjusting motor 402. A guide arc groove 401 is provided in the rotating disk 4, and the guide arc groove 401 cooperates with the positioning rod 501.

[0026] The lower pressing disc 2 is fixed on the base 1 by the connecting leg 201, and the rotating disc 4 is located at the center of the base 1 and the lower pressing disc 2. The limiting slide groove 3 can prevent the lower pressing disc 2 from interfering with the upper pressing disc 105 and the positioning rod 501. Starting the adjusting motor 402 can drive the rotating disc 4 to rotate, and the guide arc groove 401 and the positioning rod 501 cooperate with each other. Then, the rotation of the rotating disc 4 can use the guide arc groove 401 to drive the positioning rod 501 to move, and then simultaneously adjust the positioning mechanism 5 to close or spread each other.

[0027] Among them, in order to achieve the purpose of adjusting the height and extension length of the second positioning piece 502, this device adopts the following technical solutions: a limiting block 504 is fixed in the mounting hole 503, a threaded through hole 505 is opened in the limiting block 504, a limiting groove 508 is opened in the adjusting rod 507, a threaded rod 509 is rotatably installed in the limiting groove 508, the threaded rod 509 is threadedly matched with the threaded through hole 505, a threaded adjusting rod 513 is rotatably installed in the dovetail slide groove 512, a threaded adjustment hole 511 is opened in the dovetail slider 510, and the threaded adjustment hole 511 is threadedly matched with the threaded adjusting rod 513.

[0028] By threading the threaded rod 509 in cooperation with the threaded through hole 505, rotating the threaded rod 509 can drive the adjusting rod 507 to move, and the movement of the adjusting rod 507 will drive the second positioning piece 502 to move, thereby adjusting the extension distance of the second positioning piece 502, and the threaded adjusting rod 513 is threadedly engaged with the threaded adjustment hole 511, and rotating the threaded adjusting rod 513 can drive the second positioning piece 502 to move, thereby adjusting the height of the second positioning piece 502, thereby avoiding the problem that the workpiece is low and the rubber seal is placed on the workpiece, and the second positioning piece 502 cannot contact the rubber seal.

[0029] The working principle and usage process of the utility model are as follows: when in use, it is necessary to adjust the extension distance of the second positioning piece 502 according to the radius difference between the rubber seal and the workpiece, so that the extension distance of the second positioning piece 502 is the radius difference between the workpiece and the rubber seal, and the threaded adjustment rod 513 is rotated to adjust the height of the second positioning piece 502 so that the distance between the bottom of the second positioning piece 502 and the lower pressing plate 2 is slightly larger than the height of the workpiece. At this time, the workpiece can be placed on the lower pressing plate 2 with the workpiece mounting surface facing upward, the rubber seal is placed on the workpiece, and preliminarily aligned, and the adjustment motor 402 is started to drive the rotating disk 4 to rotate. The rotation of the rotating disk 4 will drive the positioning mechanism 5 to move synchronously toward the center, and the positioning rod 501 will press against the four sides of the workpiece, and the second positioning piece 502 will press against the four sides of the rubber seal, thereby completely aligning the workpiece and the rubber seal together, and starting the pressing hydraulic rod 104 drives the upper pressing plate 105 to move downward, and the upper pressing plate 105 moves downward to press the rubber seal into the workpiece.
