Description

Technical Field

[0001] This utility model belongs to the field of sealing ring assembly technology, specifically relating to an automatic sealing ring assembly fixture. Background Technology

[0002] A sealing ring is an elastic sealing element used to prevent fluid (liquid or gas) leakage. It is usually installed at the joint between two parts and mainly serves a sealing function. Sealing rings come in a variety of shapes and materials, with common types including O-rings, Y-rings, and V-rings. Therefore, in practical applications, most products or appliances that require good airtightness need to be equipped with sealing rings.

[0003] However, in the field of sealing ring assembly, sealing rings are usually installed into products or appliances manually. Because sealing rings have good elasticity, workers need to manually open the sealing ring before putting it on the product or appliance, which can easily lead to various problems, such as improper installation, missing parts, and deformation of the sealing ring. At the same time, for sealing rings with greater elasticity or those that need to be opened at a larger angle, workers need to spend more time and effort to install the sealing rings on the product or appliance, which is not only time-consuming and labor-intensive but also increases the cost of installing the sealing rings. Utility Model Content

[0005] This utility model provides an automatic sealing ring installation fixture, which aims to solve the problems of easy defects, time-consuming, labor-intensive and costly manual installation of sealing rings in the prior art.

[0006] (2) Technical solution

[0007] This utility model provides an automatic sealing ring mounting fixture, including a frame, on which an installation component and a drive component are provided. The drive component drives the installation component to move between a first position and a second position. The frame is also provided with a claw component corresponding to the first position and a fixing component corresponding to the second position. The claw component includes a loading platform, a plurality of claw arms slidably connected to the loading platform, and a first drive member for driving the claw arms to move. The claw arms are provided with protrusions. The installation component includes an installation cylinder, on which a clearance hole adapted to the protrusion is provided.

[0008] Furthermore, the loading platform is provided with an observation cavity, and a plurality of the claw arms are arranged in a circular array and at least partially slide into the observation cavity.

[0009] Furthermore, an abutment is movably connected inside the observation cavity. The abutment is connected to the output shaft of the first drive member. The abutment has a first inclined surface, and the claw arm has a second inclined surface that matches the first inclined surface.

[0010] Furthermore, the loading platform is provided with a number of fixing blocks that correspond one-to-one with the claw arm, and an elastic element abuts between the fixing block and the claw arm.

[0011] Furthermore, the claw arm has two protrusions, which are spaced apart along the length of the claw arm.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] like Figure 1-4 As shown, this utility model provides an automatic sealing ring mounting fixture, including a frame 1. The frame 1 is provided with a mounting component 2 and a drive component 3. The drive component 3 drives the mounting component 2 to move between a first position and a second position. The frame 1 is also provided with a claw component 4 corresponding to the first position and a fixing component 5 corresponding to the second position. In use, the worker needs to place the sealing ring 6 on the claw component 4 and fix the product 7 on the fixing component 5. After the drive component 3 moves the mounting component 2 to the first position, the claw component 4 sets the sealing ring 6 on the mounting component 2. Then, the drive component 3 drives the mounting component 2 and the sealing ring 6 to be synchronously transported to the second position. At this time, the mounting component 2 corresponds exactly to the position of the product 7 and sets the sealing ring 6 on the product 7, thereby completing the automated mounting operation of the sealing ring 6 on the product 7.

[0034] The claw assembly 4 includes a loading platform 41, a plurality of claw arms 42 slidably connected to the loading platform 41, and a first driving member 43 for driving the claw arms 42 to move. Each claw arm 42 has a protrusion 421. The mounting assembly 2 includes a mounting cylinder 21 with a clearance hole 211 adapted to the protrusion 421. When placing the sealing ring 6, the sealing ring 6 is placed on the top surface of each claw arm 42, and each protrusion 421 abuts against the inner side of the sealing ring 6. The first driving member 43 drives each claw arm 42 to move in a direction away from the sealing ring 6, thereby dispersing the movement of the claw arms 42 and the protrusion 421. Under the pulling force, the sealing ring 6 is opened. At this time, the mounting cylinder 21 moves downward to the inner side of the sealing ring 6 under the drive of the drive component 3, that is, the sealing ring 6 is located on the outer periphery of the mounting cylinder 21. Then, the first drive component 43 drives each of the claw arms 42 to reset. Through the setting of the clearance hole 211, each of the protrusions 421 located on the inner side of the sealing ring 6 can pass through the clearance hole 211 and move into the interior of the mounting cylinder 21 and leave the sealing ring 6. As a result, the sealing ring 6 contracts and is fastened to the outer peripheral wall of the mounting cylinder 21 under its own elastic force, thereby completing the feeding operation of the sealing ring 6 being fitted onto the mounting cylinder 21.

[0035] It should be noted that in this embodiment, the first driving member 43 is preferably a cylinder, and in order to reduce the friction between the protrusion 421 and the sealing ring 6, the protrusion 421 is a cylindrical structure.

[0036] like Figure 5As shown, the claw assembly 4 enables the sealing ring 6 to automatically expand, and the expansion angle of each sealing ring 6 is the same, thereby ensuring the accuracy and stability of the sealing ring 6 assembly and further reducing the cost of manual assembly. At the same time, since the claw assembly 4 is composed of multiple claw arms 42, the sealing ring 6 can be expanded into different shapes, such as circles and ovals, by controlling the movement stroke of different claw arms 42, thereby adapting to different shapes of mounting cylinders 21 and products 7, thus effectively improving the flexibility and versatility of the fixture.

[0037] Specifically, in order to facilitate observation of the movement of the claw arm 42, the loading platform 41 is provided with a cylindrical observation cavity 411, and each claw arm 42 is arranged in a circular array around the center of the observation cavity 411, and the end of the claw arm 42 slides into the observation cavity 411.

[0038] Furthermore, such as Figure 2-7 As shown, the output shaft of the first driving member 43 is extendable within the observation cavity 411, and an abutment member 431 is fixedly provided at the end of the output shaft of the first driving member 43, so that the abutment member 431 can move up and down within the observation cavity 411. The abutment member 431 has a frustum-shaped structure that is narrow at the top and wide at the bottom, and its peripheral wall forms a first inclined surface 432 that gradually slopes outward from top to bottom. The bottom of the claw arm 42 is provided with a second inclined surface 422 that matches the first inclined surface 432. When the first driving member 43 drives the abutment member 431 to move upward, under the guidance of the first inclined surface 432 and the second inclined surface 422, each claw arm 42 moves away from the abutment member 431 (sealing ring 6), thereby increasing the distance between each protrusion 421, and thus achieving the purpose of expanding the sealing ring 6.

[0039] Furthermore, in order to enable each claw arm 42 to move toward the observation cavity 411 for resetting when the abutment member 431 moves downward, facilitating the loading and installation of the next sealing ring 6, the peripheral wall of the loading platform 41 is provided with a plurality of fixing blocks 44 corresponding one-to-one with each claw arm 42. An elastic element 45 abuts between the fixing block 44 and the other end of the claw arm 42. The elastic element 45 can be a spring or a soft rubber material, so that when the abutment member 431 moves downward, the claw arm 42 can automatically reset under the elastic force of the elastic element 45, so that each of the protrusions 421 gathers together to facilitate the loading and assembly of the sealing ring 6.

[0040] It should be noted that since different products 7 use different mounting slots 71 for mounting the sealing ring 6, the required size of the sealing ring 6 will also vary. When the sealing ring 6 used is large, during the feeding process, the distance between the sealing ring 6 and the protrusion 421 may be too large, making it impossible to secure the sealing ring 6. This can easily lead to instability when manually placing the sealing ring 6, affecting the feeding efficiency. Therefore, in this embodiment, the claw arm 42 has two protrusions 421, which are spaced apart along the length of the claw arm 42. During feeding, the sealing ring 6 is supported and fixed between the two protrusions 421, thereby adapting to sealing rings 6 of different diameters.

[0041] Specifically, such as Figure 8-9 As shown, the mounting assembly 2 also includes a support plate 22, a second driving member 23 and a mounting block 24 respectively disposed on the support plate 22. The mounting block 24 is provided with a through hole 241. The output shaft of the second driving member 23 is connected to the mounting cylinder 21 and drives the mounting cylinder 21 to move through the through hole 241. It should be noted that the diameter of the mounting cylinder 21 is adapted to the diameter of the through hole 241. That is, when the sealing ring 6 is fitted on the outer peripheral wall of the mounting cylinder 21, the second driving member 23 drives the mounting cylinder 21 to move upward. The sealing ring 6 abuts against the bottom of the mounting block 24 and is located on the outer periphery of the through hole 241. Therefore, as the mounting cylinder 21 continues to move upward, the sealing ring 6 disengages from the mounting cylinder 21 under the blocking action of the mounting block 24.

[0042] In use, the mounting component 2 moves to the second position under the drive of the drive component 3 and is located above the product 7. At this time, since the inner diameter of the mounting cylinder 21 is larger than the outer diameter of the top of the product 7, the mounting cylinder 21 is sleeved on the product 7. In the horizontal direction, the sealing ring 6 corresponds exactly to the fitting groove 71 on the product 7. Then the mounting cylinder 21 moves upward, and the sealing ring 6 is disengaged from the mounting cylinder 21 under the blocking action of the mounting block 24 and sleeved in the fitting groove 71, thereby completing the fitting operation of the sealing ring 6.

[0043] Furthermore, in order to adjust the downward movement accuracy of the mounting cylinder 21, the mounting assembly 2 also includes a limiting block 25. One end of the limiting block 25 is connected to the output shaft of the second driving member 23, and the other end is sleeved on the mounting cylinder 21. The bottom area S1 of the limiting block 25 is larger than the cross-sectional area S2 of the through hole 241. When the downward movement distance of the mounting cylinder 21 reaches its maximum, the bottom surface of the limiting block 25 just abuts against the top surface of the mounting block 24, thereby limiting the downward movement distance of the mounting cylinder 21.

[0044] Specifically, such as Figure 10-11 As shown, the drive assembly 3 includes a third drive member 31 fixed to the frame 1 and a sliding plate 32 slidably connected to the frame 1 and connected to the output shaft of the third drive member 31; wherein, the output shaft of the third drive member 31 extends horizontally, and the sliding direction of the sliding plate 32 is consistent with the extension direction of the output shaft of the third drive member 31, so that the horizontal movement distance of the sliding plate 32 can be controlled by adjusting the extension distance of the output shaft of the third drive member 31; the third drive member 31 is preferably a cylinder;

[0045] Furthermore, the drive assembly 3 also includes a fourth drive member 33 disposed on the sliding plate 32, and a movable block 34 threadedly connected to the output shaft of the fourth drive member 33. The other end of the movable block 34 is fixedly connected to the mounting assembly 2. In this embodiment, the movable block 34 and the fourth drive member 33 are driven by a lead screw. In actual use, a cylinder or hydraulic cylinder can also be used instead. The output shaft of the fourth drive member 33 extends vertically. It should be noted that in actual applications, in order to achieve a better sealing effect for the product 7, multiple sealing rings 6 will be fitted on the same product 7. Therefore, in this embodiment, the fitting groove 71 includes a first set of grooves 711 and a second set of grooves 712 that are spaced apart vertically. During the fitting process of the sealing rings 6, the mounting assembly 2 needs to feed the product 7 twice and fit two sealing rings 6.

[0046] During the first installation, the installation component 2, under the action of the fourth driving component 33 and the moving block 34, causes the sealing ring 6 to correspond to the first sleeve groove 711 or the second sleeve groove 712 in the horizontal direction. The installation cylinder 21 moves upward, and the sealing ring 6 is sleeved in the first sleeve groove 711 or the second sleeve groove 712 under the blocking action of the installation block 24.

[0047] The second fitting is achieved by adjusting the fourth drive component 33 and the moving block 34 so that the sealing ring 6 corresponds to the second groove 712 or the first groove 711 in the horizontal direction. The above operation is repeated to complete the second fitting operation of the sealing ring 6.

[0048] By setting the fourth driving component 33 and the moving block 34, the installation component 2 can freely adjust its height according to the vertical position of different mounting slots 71, thereby achieving the purpose of automatically mounting multiple sealing rings 6 on the same product 7;

[0049] Preferably, the driving directions of the third driving member 31 and the fourth driving member 33 are perpendicular to each other.

[0050] Specifically, the frame 1 is also provided with a control console 8, which is electrically connected to the first drive component 43, the second drive component 23, the third drive component 31 and the fourth drive component 33 respectively, thereby controlling the overall movement of the fixture.

[0051] The innovation of this utility model lies in the fact that the design of the claw assembly allows the sealing ring placed inside the claw assembly to expand into different shapes by controlling the movement stroke of each claw arm to adapt to different products. At the same time, the claw arms can be moved outward by sliding the abutment member and moved inward and reset by elastic member, making the claw assembly drive more convenient and the overall structure simpler and more compact. It can also effectively reduce the defective situation of sealing ring assembly, thereby improving assembly efficiency and reducing assembly cost.

This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
