DETAILED DESCRIPTION

[0028] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0030] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships recorded in the embodiments and shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0031] like Figure 1-Figure 6 As shown, the utility model specifically relates to an O-ring set mechanism for threaded plugs, including a conveying mechanism 130 to grab a large screw plug placed on a large screw plug cutting mechanism 180 to an O-ring cutting mechanism 170, the conveying mechanism 130 includes an XZ axis servo module 131 and a screw plug clamp 132 assembled on the XZ axis servo module 131 through a rotating cylinder;

[0032] The O-ring cutting mechanism 170 includes a platform 171, a jaw opening cylinder 175 connected to the platform 171 through a linear guide rod 172, and a lifting cylinder 173 connected to the jaw opening cylinder 175, the jaw opening cylinder 175 is connected to an L-shaped jaw 1751, the platform 171 is provided with a through slot 1714 for the L-shaped jaw 1751 to pass through, and the L-shaped jaw 1751 can be linearly translated horizontally and vertically relative to the platform 171;

[0033] The lifting cylinder 173 drives the opening jaw cylinder 175 to move axially along the linear guide rod 172, and fixes the O-ring placed on the platform 171 through the L-shaped jaw 1751. The opening jaw cylinder 175 drives the L-shaped jaw 1751 to move linearly to open the O-ring, so that the screw plug jaw 132 places the large screw plug in the O-ring.

[0034] It also includes a tooling support weldment 110 that fixes the XZ axis servo module 131 and the O-ring cutting mechanism 170 .

[0035] It should be noted that, the XZ-axis servo module 131 is fixed to the tooling support weldment 110, and the large screw plug cutting mechanism 180 and the O-ring cutting mechanism 170 are also arranged on the tooling support weldment 110 and are located below the XZ-axis servo module 131. The XZ-axis servo module 131 grabs the large screw plug of the large screw plug cutting mechanism 180 to the O-ring cutting mechanism 170 through the screw plug clamp 132, so as to facilitate the O-ring at the O-ring cutting mechanism 170 to be installed on the surface of the large screw plug.

[0036] The O-ring is placed on the platform 171, and the lifting cylinder 173 drives the jaw opening cylinder 175 to move vertically upward along the axial direction of the linear guide rod 172, so that the L-shaped jaw 1751 is sleeved on the inner side of the O-ring. At this time, the L-shaped jaw 1751 is not opened, and the O-ring can just be sleeved on the surface of the L-shaped jaw 1751. When the L-shaped jaw 1751 reaches the specified position, the jaw opening cylinder 175 drives the L-shaped jaw 1751 to translate linearly relative to the platform 171, and the L-shaped jaw 1751 opens the O-ring. At this time, the inner diameter of the O-ring becomes larger than the initial state; in addition, the XZ axis servo module 131 inserts the large screw plug into the O-ring through the screw plug jaw 132. When the large screw plug reaches the specified position, the L-shaped jaw 1751 is closed by the jaw opening cylinder 175. During the closing process, the O-ring is sleeved on the surface of the large screw plug.

[0037] Compared with manually installing the O-ring on the surface of the large screw plug, the use of automated control not only greatly improves the assembly efficiency, but also ensures the assembly accuracy and pass rate.

[0038] The jaw opening cylinder 175 is connected to the linear guide rod 172 through a lifting linear bearing 1752, and can move along the axial direction of the linear guide rod 172 to drive the L-shaped jaw 1751 to move vertically up and down, thereby ensuring the smoothness and stability of the jaw opening cylinder 175 during movement, and further ensuring that the L-shaped jaw 1751 can accurately fix and open the O-ring.

[0039] The platform 171 is provided with a placement groove 1712 , a material supply groove 1711 and a material pushing groove 1713 . The placement groove 1712 , the material supply groove 1711 , the material pushing groove 1713 and the through groove 1714 are interconnected. The material pushing groove 1713 is connected to a material pushing mechanism 174 .

[0040] Among them, the placement groove 1712 and the through groove 1714 are connected, and the O-ring needs to reach the position of the placement groove 1712 at the end. When the O-ring has not reached the placement groove 1712, the L-shaped clamp 1751 is located in the through groove 1714 and will not extend out of the placement groove 1712, so as to avoid interference when the O-ring moves to the placement groove 1712. In addition, when the O-ring reaches the placement groove 1712, the L-shaped clamp 1751 extends out of the placement groove 1712 and passes through the O-ring to fix the O-ring and can stretch the O-ring.

[0041] The feed trough 1711 is connected to the place where the O-ring is fed. When the O-ring reaches the pushing trough 1713 from the feed trough 1711, the pushing mechanism 174 pushes the O-ring in the pushing trough 1713 to the placement groove 1712 so that the L-shaped clamp 1751 fixes and opens the O-ring.

[0042] The pushing mechanism 174 includes a pushing cylinder 1741 arranged on the platform 171 and a pushing V-shaped fork plate 1742 connected to the pushing cylinder 1741. The pushing V-shaped fork plate 1742 can be inserted into the pushing groove 1713 and move linearly along the length direction of the platform 171 to push the O-ring in the pushing groove 1713 to the placement groove 1712.

[0043] The platform 171 is provided with a limit stopper 176 located above the placement groove 1712 and used in conjunction with the L-shaped clamping claw 1751 , and sensors 177 are provided on opposite sides of the limit stopper 176 .

[0044] Among them, the inner diameter of the limit block is larger than the outer diameter of the large screw plug, and the inner diameter of the limit block is smaller than the outer diameter of the O-ring after it is expanded. Therefore, when the large screw plug is inserted into the O-ring, the L-shaped clamp 1751 closes and moves vertically downward, and the O-ring is limited by the limit block to ensure that the O-ring can be well fitted on the surface of the large screw plug.

[0045] In addition, the sensor 177 can detect whether the O-ring is fully expanded.

[0046] An O-ring detection mechanism 160 is also provided on one side of the O-ring cutting mechanism 170 . The O-ring detection mechanism 160 includes a large screw plug clamping assembly 161 for fixing the large screw plug, a small screw plug clamping assembly 162 and a visual camera 163 .

[0047] The O-ring detection mechanism 160 is used to detect whether the O-ring on the surface of the large screw plug is properly installed. Compared with manual visual detection, the detection efficiency is greatly improved, and the detection accuracy is also improved.

[0048] In addition, the large screw plug clamping assembly 161 and the small screw plug clamping assembly 162 are structures for fixing the large screw plug and the small screw plug. This structure is a conventional design in the prior art and will not be described in detail here.

[0049] Furthermore, the large screw plug and the small screw plug are only different in size, and their structures are the same. Among them, the small screw plug does not need to be equipped with an O-ring, while the large screw plug needs to be equipped with a sealing ring. As for why the small screw plug does not need to be equipped with a sealing ring, it is based on the process requirements of the product. Therefore, it will not be described in detail.

[0050] A small screw plugging and cutting mechanism 150 is also provided on one side of the O-ring detection mechanism 160 . The small screw plugging and cutting mechanism 150 has the same structure as the large screw plugging and cutting mechanism 180 .

[0051] It also includes vibration plate feeding components 140 respectively located upstream of the small screw plug cutting mechanism 150, and the vibration plate feeding components 140 are provided with three groups, and the three groups of vibration plate feeding components 140 correspond to the small screw plug cutting mechanism 150, the O-ring cutting mechanism 170 and the large screw plug cutting mechanism 180 respectively.

[0052] It should be noted that, the vibration plate feeding assembly 140 is fixed upstream of the small screw plug cutting mechanism 150 through the vibration plate supporting weldment 120, and the vibration plate feeding assembly 140, the large screw plug cutting mechanism 180 and the small screw plug cutting mechanism 150 are conventional means in the prior art. The material is transported by the vibration plate feeding mechanism, and the large screw plug cutting mechanism 180, the small screw plug cutting mechanism 150 and the O-ring cutting mechanism 170 respectively cut out the material to ensure that only one material is transported each time, and finally the assembly of the O-ring and the large screw plug is completed in the O-ring cutting mechanism 170. The specific structural principle will not be described in detail.

[0053] An NG material removal component 190 is also disposed on the outer side of the large screw plugging and cutting mechanism 180 , and the NG material removal component 190 includes a material box.

[0054] The NG blanking assembly 190 is provided so as to collect the large screw plugs with unqualified O-ring sets.

[0055] The above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solution of the present invention rather than to limit it. The protection scope of the present invention is not limited thereto. Although the present invention is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that any technician familiar with the technical field can still modify the technical solution recorded in the aforementioned embodiments within the technical scope disclosed by the present invention, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solution of the embodiment of the present invention, and should all be covered within the protection scope of the present invention.
