Description

Technical Field

[0001] This utility model relates to the field of automatic assembly technology of sealing rings, and in particular to a sealing ring deformation device. Background Technology

[0002] The automated assembly of internal sealing rings has developed rapidly, with deformation assembly being the mainstream automated assembly method.

[0003] Chinese patent CN202021931490.4 discloses an internal sealing ring installation device, including an elastic push rod, a shrinkage sleeve, a transition tube, and a push rod. The shrinkage sleeve has a shrinkage through hole with a trapezoidal vertical cross-section. The larger end of the shrinkage through hole is the inlet end, and the smaller end is the outlet end. The inlet end of the shrinkage sleeve matches the outer diameter of the internal sealing ring, and the outlet end of the shrinkage sleeve matches the inner diameter of the transition tube. The transition tube is a hollow tubular structure. The elastic push rod has elastic claws that bend and compress the internal sealing ring from the shrinkage through hole of the shrinkage sleeve and then feed it into the transition tube. The transition tube delivers the internal sealing ring into the mounting hole of the workpiece. This invention automates the assembly of internal sealing rings, especially automating the installation of internal sealing rings in small-sized internal threaded holes, greatly improving production efficiency and reducing labor costs.

[0004] However, in this technical solution, the deformation method of the sealing ring is that the conical shrink sleeve and the elastic claw fingers set for shrinkage squeeze the sealing ring, causing the sealing ring to bend upward. The bending deformation process cannot guarantee uniform deformation, resulting in technical problems such as low assembly accuracy and low assembly efficiency of the sealing ring. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a sealing ring deformation device. This invention uses a deformation component to deform the sealing ring from a circular structure to a U-shaped structure, thereby reducing the outer contour size of the sealing ring. In conjunction with a material transfer component, the deformed sealing ring is transferred. When internal sealing assembly is required, the discharge rod pushes the sealing ring out of the material receiving cylinder, thus realizing the automatic assembly of the internal sealing ring and solving the problem of low efficiency in the automatic assembly of internal sealing rings in existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sealing ring deformation device includes: a base; and further includes: a deformation component, which is mounted on the base and deforms the sealing ring to a shape with an outer contour smaller than that of the sealing ring in its natural state; and a transfer component, which holds the deformed sealing ring in its deformed state and transfers it to the product to be assembled.

[0008] According to one embodiment of the present invention, the deformation component includes: a guide plate having a guide groove; the guide groove sequentially including a push guide section, a deformation guide section, and a deformation holding section; a push plate slidably disposed on the guide plate; a deformation push rod slidably disposed in the guide groove and moving synchronously with the push plate; and a push plate drive unit that drives the push plate to reciprocate, which is installed on one side of the base and has its output end connected to the push plate.

[0009] According to one embodiment of the present invention, the front end of the deformation push rod is provided with a forming part, the front end of the forming part is provided with an arc structure, and a protrusion for extruding the deformation sealing ring is provided in the middle of the arc structure. A deformation holding space is formed between the forming part and the inner wall of the deformation holding section.

[0010] According to one embodiment of the present invention, the deformation guide section includes a feeding section and a deformation section with gradually decreasing size.

[0011] According to one embodiment of the present invention, the push guide section is arranged in parallel, and the contour of the deformation retaining section is adapted to the contour of the deformed sealing ring.

[0012] According to one embodiment of the present invention, the deformation push rod moves forward, pushing the sealing ring to move along the deformation guide section, and deforms in the gradually decreasing deformation guide section, so that the part of the sealing ring that contacts the protrusion is concave inward to form a double-layer U-shaped structure.

[0013] According to one embodiment of the present invention, it further includes a material ejection assembly disposed below the guide plate for ejecting the deformed sealing ring.

[0014] According to one embodiment of the present invention, the ejection assembly includes: an ejection rod, which is vertically and reciprocatingly arranged, and its top end can pass through the guide plate and the push plate to eject the sealing ring from the deformation holding section; the top contour of the ejection rod is adapted to the contour of the deformation holding space; and an ejection drive unit, which is mounted on the base and the output end of the ejection drive unit is connected to the ejection rod.

[0015] According to one embodiment of the present invention, the bottom of the deformation holding section is provided with a through hole adapted to the deformation holding space, and the ejector rod is inserted into the through hole and is adapted to the size of the through hole.

[0016] According to one embodiment of the present invention, the material transfer assembly includes: a horizontal moving module; a first vertical moving module mounted on the horizontal moving module; a second vertical moving module mounted on the first vertical moving module; a material picking cylinder mounted on the first vertical moving module; and a material discharging rod mounted on the second vertical moving module, wherein the second vertical moving module drives the material discharging rod to reciprocate vertically.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) This utility model uses a deformation component to deform the sealing ring from a circular structure to a U-shaped structure, thereby reducing the outer contour size of the sealing ring. It also uses a material transfer component to transfer the deformed sealing ring. When the inner sealing assembly is required, the discharge rod pushes the sealing ring out of the material taking cylinder to achieve automatic assembly of the inner sealing ring.

[0019] (2) This utility model sets a deformation push rod and a guide plate at the bottom of the push plate to realize the spatial pushing of the sealing ring in three directions: upper, lower and tail. The sealing ring is pushed in the forward direction, which improves the deformation quality of the sealing ring and avoids the sealing ring from running around randomly, resulting in inconsistent quality after deformation.

[0020] (3) This utility model achieves support before deformation of the sealing ring and automatic unloading after deformation by setting the unloading rod. It has a clever structure and high unloading efficiency.

[0021] (4) This utility model uses a material transfer component in conjunction with a material ejection component to automatically eject the sealing ring and grab it according to its deformed state, thereby realizing the rapid transfer of the deformed sealing ring;

[0022] (5) This utility model pushes out the sealing ring in the material taking cylinder by the discharge rod, realizing the automatic assembly of the inner sealing ring, which has high production efficiency and high sealing ring assembly accuracy.

[0023] (6) This utility model achieves efficient assembly by deforming or grasping two sealing rings in one action through a symmetrical structural design.

[0024] In summary, this utility model has the advantages of stable sealing ring deformation quality, high efficiency, and automated assembly. Attached Figure Description

[0041] Example 1

[0042] like Figure 1 As shown, this embodiment provides a sealing ring deformation device, including: a base 1, which has a double-sided structure design, including an upper support plate 11 and a lower support plate 12, supported by several support rods 13 in the middle; it also includes: a deformation component 2, which is installed above the base 1, and the deformation component 2 deforms the circular sealing ring 100 into a state where the outer contour is smaller than the contour of the sealing ring 100 in its natural state, so that the deformed sealing ring 100 can be smoothly assembled into the sealing part that needs to be sealed internally; specifically, when the sealing part for internal sealing, such as the inner diameter surface of a tubular structure, needs to be sealed, the contour of the sealing ring 100 is deformed into a state smaller than the contour size of the inner diameter surface, so that the sealing ring 100 can be smoothly assembled into the inner diameter surface, and the automatic elastic recovery of the sealing ring 100 realizes the automatic assembly of the inner sealing ring 100; and a material transfer component 3, which holds the deformed sealing ring 100 of the deformation component 2 in a deformed state and transfers it to the product to be assembled.

[0043] Preferred, such as Figures 2-4 As shown, the deformation component 2 includes:

[0044] Guide plate 21, on which a guide groove 211 is provided; the guide groove 211 includes, in sequence, a pushing guide section 2111, a deformation guide section 2112, and a deformation holding section 2113.

[0045] A push plate 22 is slidably disposed on the guide plate 21. The push plate 22 limits the upper part of the guide groove 211, so that the sealing ring 100 moves smoothly along the guide groove 211. The push plate 22 pushes the sealing ring 100 from the deformation guide section 2112 to the deformation holding section 2113, completing the deformation of the sealing ring 100. Specifically, the push plate 22 is slidably disposed above the base 1, and guide rails are provided on both sides of the push plate 22.

[0046] Deformation push rod 23 is slidably disposed in the guide groove 211 and moves synchronously with the push plate 22. Specifically, the deformation push rod 23 is installed on the bottom of the push plate 22 by fasteners. As the push plate 22 moves, it pushes the sealing ring 100 from the deformation guide section 2112 to the deformation holding section 2113. The protrusion 232 causes the sealing ring 100 to deform inward, thereby reducing the outline of the sealing ring 100.

[0047] The push plate drive unit 24 drives the push plate 22 to move back and forth. It is installed on one side of the base 1 and its output end is connected to the push plate 22.

[0048] As an improvement, such as Figure 3 As shown, the front end of the deformation push rod 23 is provided with a forming part 231. The front end of the forming part 231 is set in an arc structure, and a protrusion 232 for extruding and deforming the sealing ring 100 is provided in the middle of the arc structure. A deformation holding space is formed between the forming part 231 and the inner wall of the deformation holding section 2113. Specifically, when the deformation push rod 23 moves to the front end, the forming part 231 and the arc section of the deformation holding section 2113 form a circular deformation holding space, that is, the outer contour of the sealing ring 100 is deformed into an approximately circular structure, so as to facilitate the material removal in the subsequent process.

[0049] Preferred, such as Figure 4 As shown, the deformation guide section 2112 includes a feeding section 21121 and a deformation section 21122 with gradually decreasing size. The outline of the feeding section 21121 is adapted to the outline size of the sealing ring 100 in its natural state.

[0050] Furthermore, the push guide section 2111 is arranged in parallel, and the contour of the deformation retaining section 2113 is adapted to the contour of the deformed sealing ring 100; specifically, it is preferably a U-shaped structure, and the bottom of the U-shaped structure is a semi-circular structure.

[0051] Furthermore, such as Figure 8As shown, the deformation push rod 23 moves forward, pushing the sealing ring 100 to move along the deformation guide section 2112, and deforms in the gradually decreasing deformation guide section 2112, so that the part of the sealing ring 100 that contacts the protrusion 232 is concave inward to form a double-layer U-shaped structure, thereby reducing the outer contour size of the sealing ring 100.

[0052] Example 2

[0053] like Figure 2 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0054] In this embodiment, a material ejection assembly 4 is also provided below the guide plate 21 to eject the deformed sealing ring 100.

[0055] As an improvement, the unloading assembly 4 includes:

[0056] The ejector rod 41 is vertically downward reciprocating, and its top end can pass through the guide plate 21 and the push plate 22 to push out the self-deformation retaining section 2113 of the sealing ring 100; the top contour of the ejector rod 41 is adapted to the contour of the deformation retaining space; that is, the side wall of the ejector rod 41 is provided with an avoidance groove 411, and the contour of the avoidance groove 411 is adapted to the contour of the protrusion 232;

[0057] And a material ejection drive unit 42, which is mounted on the base 1, and the output end of the material ejection drive unit 42 is connected to the material ejection rod 41; the material ejection drive unit 42 can be driven by a cylinder, hydraulic transmission or other means.

[0058] Preferably, the bottom of the deformation holding section 2113 is provided with a through hole adapted to the deformation holding space. The ejector rod 41 is inserted into the through hole and is adapted to the size of the through hole. When the sealing ring 100 deforms, the top surface of the ejector rod 41 is flush with the bottom surface of the deformation holding section 2113, so that the bottom surface of the deformation holding section 2113 is planar. When the forming part 231 moves forward to deform the sealing ring 100, the clearance groove 411 corresponds to the protrusion 232. When it is necessary to eject the deformed sealing ring 100, the ejector rod 41 moves upward to push out the deformed sealing ring 100.

[0059] Example 3

[0060] like Figures 6-7 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 3 and Embodiment 1 is as follows:

[0061] In this embodiment, the transfer component 3 includes:

[0062] The horizontal moving module 31 includes a first connecting plate 311, a first driving member 312, and a first guide rail slider 313. The first connecting plate 311 is slidably disposed above the deformation component 2 via the first guide rail slider 313. The output end of the first driving member 312 is connected to the first connecting plate 311, driving the first connecting plate 311 to reciprocate.

[0063] A first vertical moving module 32 is mounted on the horizontal moving module 31. Specifically, the first vertical moving module 32 includes a second connecting plate 321, a second driving member 322, and a second guide rail slider 323. The second connecting plate 321 is slidably disposed on one side of the first connecting plate 311 via the second guide rail slider 323. The second driving member 322 is disposed at the top of the first connecting plate 311, and its output end is connected to the second connecting plate 321, driving the second connecting plate 321 to move vertically back and forth.

[0064] A second vertical moving module 33 is mounted on the first vertical moving module 32. The second vertical moving module 33 includes a third driving component 331, which is mounted on one side of the second connecting plate 321, and its output end is connected to a discharge rod 35.

[0065] Material picking cylinder 34 is installed on the first vertical moving module 32. Specifically, the material picking cylinder 34 is installed at the bottom of the second connecting plate 321.

[0066] And a discharge rod 35, which is mounted on the second vertical moving module 33. The second vertical moving module 33 drives the discharge rod 35 to move vertically back and forth, so that the discharge rod 35 slides in the material taking cylinder 34. Specifically, the top end of the discharge rod 35 is connected to the output end of the third driving member 331, and its lower end is slidably disposed in the material taking cylinder 34.

[0067] Specifically, the horizontal moving module 31 drives the first vertical moving module 32 to reciprocate, and the first vertical moving module 32 drives the picking cylinder 34 to reciprocate vertically. When picking up material, the picking cylinder 34 moves downward with the first vertical moving module 32 and inserts into the upper part of the deformation holding space to abut against the deformed sealing ring 100. The ejector rod 41 moves upward and pushes the deformed sealing ring 100 into the inner cavity of the picking cylinder 34. During the pushing process, the discharge rod 35 moves upward synchronously, so that the sealing ring 100 keeps moving upward smoothly and enters the inner cavity of the picking cylinder 34.

[0068] Subsequently, through the cooperation of the horizontal moving module 31, the first vertical moving module 32, and the second vertical moving module 33, the material picking cylinder 34 is sent to the corresponding inner hole of the product to be assembled. Then, the material discharge rod 35 moves downward and pushes the deformed sealing ring 100 into the inner hole of the product to be assembled, thus completing the automatic assembly of the inner sealing ring 100.

[0069] The horizontal moving module 31, the first vertical moving module 32, and the second vertical moving module 33 each include a support frame, a driving component, and a guide rail.

[0070] Example 4

[0071] like Figure 1 As shown, components that are the same as or corresponding to those in Embodiment 3 are referred to using the same reference numerals as those in Embodiment 3. For simplicity, only the differences from Embodiment 3 will be described below. The difference between Embodiment 4 and Embodiment 3 is as follows:

[0072] In this embodiment, the guide groove 211 is symmetrically opened on the guide plate 21, and the push plate 22 simultaneously drives two sets of deformation push rods 23 to realize the simultaneous deformation of the two sets of sealing rings 100.

[0073] In addition, two sets of ejector bars 41 are provided, which are synchronously driven by a set of ejector drive units 42 to achieve efficient ejection.

[0074] In addition, two sets of material picking cylinders 34 and material discharge rods 35 are provided to achieve synchronous material picking.

[0075] Work steps

[0076] Step 1: Loading the sealing ring. The sealing ring 100 is loaded into the feeding section 21121 by a robotic arm.

[0077] Step 2: Deformation of the sealing ring. The push plate drive unit 24 drives the push plate 22 to move, so that the deformation push rod 23 moves the sealing ring 100 forward along the deformation guide section 2112 and gradually deforms it, pushing it to the deformation holding section 2113 to complete the deformation.

[0078] Step 3: Unloading. The material taking cylinder 34 moves downward with the first vertical moving module 32 and inserts into the upper part of the deformation holding space to abut against the deformed sealing ring 100. The unloading rod 41 moves upward and pushes the deformed sealing ring 100 into the inner cavity of the material taking cylinder 34. During the pushing process, the discharge rod 35 moves upward synchronously, so that the sealing ring 100 keeps moving upward smoothly and enters the inner cavity of the material taking cylinder 34.

[0079] Step 4: Inner seal assembly. Through the cooperation of the horizontal moving module 31, the first vertical moving module 32, and the second vertical moving module 33, the material picking cylinder 34 is sent to the corresponding inner hole of the product to be assembled and aligned. Then, the material discharge rod 35 moves downward and pushes the deformed sealing ring 100 into the inner hole of the product to be assembled, thus completing the automatic assembly of the inner sealing ring 100.
