Description

Technical Field

[0001] This invention relates to the field of press-fit rubber ring assembly technology, specifically a press-fit rubber ring fixture and a method for gripping rubber rings. Background Technology

[0002] Rubber rings are generally made of elastic material and are widely used on the mating surfaces of assembled structures to improve the sealing performance of assembled structures. The rubber rings commonly used are generally U-shaped.

[0003] In traditional technology centers, the assembly of soft "U"-shaped rubber rings onto rigid connectors is usually done manually by operators. Since the rubber ring provides a seal only if it is tightly connected to the connector, the assembled rubber ring is generally close in size to the slot or ring on the connector. Therefore, during assembly, the operator needs to pry open the rubber ring and fasten it into the slot or ring, and then flatten the rubber ring to complete the assembly of one rubber ring.

[0004] However, when installing the rubber ring in the above manner, the rubber ring will not be flat when it is snapped onto the connector after being pried open by force. As a result, the tight connection between the rubber ring and the connector cannot be guaranteed. At the same time, due to the elasticity and flexibility of the rubber ring, any lateral deviation during assembly will affect the final connection state between the rubber ring and the connector, thereby affecting the performance of the rubber ring and further affecting the use of the connector.

[0005] Therefore, a pressure-fitting fixture for rubber rings and a method for gripping rubber rings are proposed to address the above problems. Summary of the Invention

[0014] Preferably, an upper fixing plate is fixed to the surface of the upper fixture base plate via guide posts, and a fixing base is fixed to the surface of the upper fixing plate corresponding to the guide posts; the guide posts and the fixing base are fixed together by locking nuts.

[0015] A method for gripping rubber rings using a press-fitting rubber ring fixture, the method comprising the following steps:

[0016] S1: First, place the rubber ring on the rubber ring conformal block on the bottom plate of the lower fixture;

[0017] S2: The electric cylinder is controlled to move the gripping unit down to the position of the rubber ring contour block;

[0018] S3: The control cylinder drives the first gripper to separate from the second gripper and continues to move down to directly above the rubber ring;

[0019] S4: The spring-loaded pin on the bottom plate of the lower fixture is lifted up, and the rubber ring is filled into the rubber ring contour groove.

[0020] S5: The cylinder retraction drives the gripper one and gripper two to tighten towards each other, clamping the inner side of the bottom of the rubber ring;

[0021] S6: Control the electric cylinder to lift, the rubber ring is lifted synchronously with the first and second grippers, and the first and second grippers move relative to each other to pull the bottom edge of the rubber ring outward.

[0022] S7: Drive the electric cylinder and its bottom upper fixture base plate to move horizontally on the slide rail until it is directly above the housing to be installed;

[0023] S8: Drive the electric cylinder again to drive the upper fixture base plate to move down to the surface of the housing to be installed. At this time, control the cylinder to separate the gripper one from the gripper two.

[0024] S9: The rubber rings are removed from both sides of the gripping unit and pushed downwards by the springs to disengage from the rubber ring grooves;

[0025] S10: The rubber ring hangs down on the surface of the housing to be installed, waiting for the next pressing step.

[0026] The advantages of this invention are:

[0027] 1. This invention uses a mechanical method to replace manual labor. Specifically, by setting up an upper fixture base plate and a lower fixture base plate, the operator can control the movement of an electric cylinder when gripping the rubber ring, aligning the upper and lower fixture base plates. By lowering the gripping unit, the rubber ring, manually placed on the rubber ring contour block, can be fed into the rubber ring contour groove at the bottom of the upper fixture base plate, achieving accurate gripping of the rubber ring. Simultaneously, the gripping unit grips the rubber ring in the contour groove and expands its bottom, making it easier to fasten onto the housing to be installed. This replaces manual labor, reduces labor costs, and expands the rubber ring from multiple angles, preventing unevenness during assembly and ensuring a tight connection between the rubber ring and the connector.

[0028] 2. This invention uses a cylinder to control the relative movement of gripper one and gripper two, i.e., moving them away from each other. At this time, the electric cylinder in the slot moves the gripping unit downward, so that gripper one and gripper two are on the bottom sides of the rubber ring. Then, after the rubber ring pops out of the rubber ring contour block, it enters the rubber ring contour groove. Gripper one and gripper two expand the rubber ring, and under the control of the electric cylinder, drive the rubber ring to rise synchronously, achieving the gripping effect of the rubber ring. By using gripper one and gripper two to move synchronously driven by the cylinder, the rubber ring is opened. Compared with manually prying open the rubber ring, it is easier to maintain the flatness of the rubber ring after installation. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-6 As shown, a press-fit rubber ring fixture includes a support plate 25; a slide rail 26 is fixedly connected to the surface of the support plate 25; a support plate 27 is slidably connected inside the slide rail 26; a vertically arranged electric cylinder 24 is fixedly connected to the support plate 27; and a fixture unit is fixedly connected to the output end of the electric cylinder 24.

[0039] The fixture unit includes a lower fixture base plate 1 and an upper fixture base plate 4; the upper fixture base plate 4 is fixedly connected to the output end of the electric cylinder 24; the lower fixture base plate 1 is vertically arranged directly below the upper fixture base plate 4; a rubber ring contour block 2 is fixedly connected to the lower fixture base plate 1, and a rubber ring contour groove 23 is opened at the bottom of the upper fixture base plate 4; a gripping unit is fixedly connected to the middle of the four sides of the upper fixture base plate 4, and the gripping unit is used to grip the rubber ring in the rubber ring contour block 2.

[0040] Specifically, in existing technologies, when installing rubber rings manually using traditional methods, the rubber rings are often unevenly installed after being forcefully pried open and fastened to the connector. This compromises the tightness of the connection between the rubber ring and the connector. Furthermore, due to the elasticity and flexibility of the rubber rings, any lateral misalignment during assembly affects the final connection between the rubber ring and the connector, thus impacting the performance of the rubber ring and, consequently, the usability of the connector. This new device replaces manual labor with a mechanical approach. By using an upper fixture base plate 4 and a lower fixture base plate 1, the operator can control the electric cylinder 2 when gripping the rubber ring. 4. The movement aligns the upper fixture base plate 4 with the lower fixture base plate 1. By lowering the gripping unit, the rubber rings manually placed on the rubber ring contour block 2 can be fed into the rubber ring contour groove 23 at the bottom of the upper fixture base plate 4, achieving accurate gripping of the rubber rings. At the same time, the gripping unit grips the rubber rings in the rubber ring contour groove 23 and expands the bottom of the rubber rings, making them easier to fasten onto the housing to be installed. This replaces manual labor, reduces labor costs, and expands the rubber rings from multiple angles to avoid unevenness during assembly, ensuring a tight connection between the rubber rings and the connectors.

[0041] In one embodiment of the present invention, the gripping unit includes a cylinder 15; the cylinder 15 is fixedly connected to the surface of the upper fixture base plate 4, and a first gripper 11 and a second gripper 12 are slidably connected on both sides of the cylinder 15; the first gripper 11 and the second gripper 12 are symmetrically arranged and move on both sides of the rubber ring contour groove 23 respectively.

[0042] Specifically, when gripping the rubber ring on the rubber ring contour block 2, the cylinder 15 controls the relative movement of gripper 11 and gripper 212, i.e., moving them away from each other. At this time, the electric cylinder 24 is operated again to drive the gripping unit to move down, so that gripper 11 and gripper 212 are on the bottom sides of the rubber ring. Then, after the rubber ring pops out of the rubber ring contour block 2, it enters the rubber ring contour groove 23. The gripper 11 and gripper 212 expand the rubber ring, and under the control of the electric cylinder 24, the rubber ring rises synchronously, achieving the gripping effect of the rubber ring. The structure of gripper 11 and gripper 212 is set as a plate, and there are two protrusions on the inner side of the plate, which are used to support the inner side of the rubber ring.

[0043] In one embodiment of the present invention, the output end of the cylinder 15 is fixedly connected to two sets of fixed seats 14, and the two sets of fixed seats 14 slide symmetrically; the first clamp 11 and the second clamp 12 are respectively fixedly connected to the bottom of the two sets of fixed seats 14 by the third bolt 13.

[0044] Specifically, the cylinder 15 can control the symmetrical sliding of the two sets of fixed seats 14 through air intake, that is, synchronously approaching or synchronously moving away. The first clamp 11 and the second clamp 12 are respectively fixed to the bottom of the two sets of fixed seats 14 by the third bolt 13. Therefore, when the two sets of fixed seats 14 approach or move away from each other, they can drive the first clamp 11 and the second clamp 12 to approach or move away from each other. As mentioned above, after the first clamp 11 and the second clamp 12 are located on both sides of the bottom of the rubber ring, during the process of lifting the rubber ring, the rubber ring can be pushed into the rubber ring contour groove 23. At this time, the first clamp 11 and the second clamp 12 move away from each other, which can support the rubber ring and expand its bottom, making it easier to fasten the rubber ring onto the housing to be installed.

[0045] In one embodiment of the present invention, the rubber ring contour blocks 2 on the surface of the lower fixture base plate 1 are arranged intermittently, and spring top posts are arranged between adjacent rubber ring contour blocks 2.

[0046] Specifically, gaps are left between the intermittent rubber ring contour blocks 2 on the lower fixture base plate 1, and holes are drilled in the lower fixture base plate 1. The spring-loaded pin is placed in the hole and installed at the same time. When the gripper 11 and gripper 22 move to both sides of the rubber ring, the spring-loaded pin is lifted by the external cylinder 15 and pushes the rubber ring up and down, so that it falls into the rubber ring contour groove 23 in the upper fixture base plate 4.

[0047] In one embodiment of the present invention, a pushing unit is fixedly connected to the surface of the upper fixture base plate 4, and the pushing unit includes a support block 6; a bolt 7 is connected through the middle of the support block 6, and the top of the bolt 7 is fixed by a locking nut 9; the two sides of the support block 6 are fixed to the surface of the upper fixture base plate 4 by bolts 8; a locking nut 5 is provided on the surface of the upper fixture base plate 4 corresponding to the bolt 7; the bottom of the bolt 7 extends into the rubber ring groove 23 at the bottom of the lower fixture base plate 1; the support block 6 is configured as a U-shaped structure; a spring 22 is sleeved on the bolt 7, and the two ends of the spring 22 are located between the support block 6 and the upper fixture base plate 4.

[0048] Specifically, after the rubber ring is gripped and expanded by the first gripper 11 and the second gripper 12, the electric cylinder 24 moves the gripping unit, the pushing unit, and the upper fixture base plate 4 together to the top of the housing to be installed. Then, the electric cylinder 24 controls the gripping unit, the pushing unit, and the upper fixture base plate 4 to move down to the surface of the housing to be installed, so that the rubber ring is placed on the surface of the housing to be installed. Then, the slot cylinder 15 separates the first gripper 11 and the second gripper 12, so that the rubber ring is removed from the gripper 11 and the second gripper 12. At this time, the bolt penetrating the middle of the support block 6, under the action of the spring 22, will push the rubber ring out of the upper fixture contour groove and let it hang down on the surface of the housing to be installed. At this point, the entire gripping and placement process of the rubber ring is completed, and it can wait for the next step of pressing. Among them, the upper end of the first bolt 7 is provided with The bolt 7 has threads and mates with locking nut 29. The lower end of bolt 7 has threads and mates with locking nut 5. The middle part of bolt 7 is a smooth rod. Spring 22 passes through bolt 7, with one end locked inside support block 6 and the other end locked on the upper surface of upper fixture base plate 4. When the rubber ring is gripped into the upper fixture contour groove at the bottom of upper fixture base plate 4, bolt 7 is pushed to move locking nut 29 upward. When gripper 11 is released, the rubber ring is placed on the part. Bolt 7 drives locking nut 29 and locking nut 5 to move downward under the push of spring 22 until locking nut 29 is locked at the upper end of support block 6, which serves as a travel stop. Similarly, locking nut 5 is locked on upper fixture base plate 4 to prevent spring 22 from extending indefinitely and to push rubber ring.

[0049] In one embodiment of the present invention, fixing pins 10 are fixedly connected to the four corners of the bottom of the upper fixture base plate 4, and holes are provided at the four corners of the surface of the lower fixture base plate 1; the fixing pins 10 are engaged with the holes.

[0050] In one embodiment of the present invention, an upper fixing plate 17 is fixedly connected to the surface of the upper fixture base plate 4 via a guide post 16, and a fixing base 18 is fixedly connected to the surface of the upper fixing plate 17 corresponding to the guide post 16; the guide post 16 and the fixing base 18 are fixed by a locking nut 19.

[0051] A method for gripping rubber rings using a press-fitting rubber ring fixture, the method comprising the following steps:

[0052] S1: First, place the rubber ring on the rubber ring conformal block 2 on the bottom plate 1 of the lower fixture;

[0053] S2: Control the electric cylinder 24 to move the gripping unit down to the position of the rubber ring contour block 2;

[0054] S3: The control cylinder 15 drives the first gripper 11 to separate from the second gripper 12, and continues to move down to directly above the rubber ring;

[0055] S4: The spring-loaded pin on the bottom plate 1 of the lower fixture is lifted up, and the rubber ring is driven to fill into the rubber ring contour groove 23;

[0056] S5: The cylinder 15 retracts and drives the first gripper 11 and the second gripper 12 to tighten towards each other, clamping the inner side of the bottom of the rubber ring.

[0057] S6: Control the electric cylinder 24 to lift, the rubber ring is lifted synchronously with the first clamp 11 and the second clamp 12, and at the same time the first clamp 11 and the second clamp 12 move relative to each other to pull the bottom edge of the rubber ring outward.

[0058] S7: Drive the electric cylinder 24 and its bottom upper fixture base plate 4 to move horizontally on the slide rail 26 until it moves directly above the housing to be installed;

[0059] S8: Drive the electric cylinder 24 again to drive the upper fixture base plate 4 to move down to the surface of the housing to be installed. At this time, operate the cylinder 15 to separate the gripper 11 from the gripper 22.

[0060] S9: The rubber ring is removed from both sides of the gripping unit and pushed downward by the spring 22 to disengage from the rubber ring contour groove 23;

[0061] S10: The rubber ring hangs down on the surface of the housing to be installed, waiting for the next pressing step.

[0062] Working Principle: In existing technologies, when installing rubber rings manually using traditional methods, the rings are often unevenly installed after being forcefully pried open and fastened to the connector. This compromises the tightness of the connection between the ring and the connector. Furthermore, due to the elasticity and flexibility of the rubber rings, any lateral misalignment during assembly affects the final connection, thus impacting the performance of the rings and ultimately the usability of the connector. This device replaces manual labor with a mechanical approach, utilizing an upper fixture base plate 4 and a lower fixture base plate 1. When gripping the rubber ring, the operator can control the electric cylinder 24 to move, aligning the upper fixture base plate 4 with the lower fixture base plate 1. By lowering the gripping unit, the rubber ring, manually placed on the rubber ring contour block 2, can be fed into the rubber ring contour groove 23 at the bottom of the upper fixture base plate 4, achieving accurate gripping of the rubber ring. Simultaneously, the gripping unit grips the rubber ring in the contour groove 23 and expands its bottom, making it easier to fasten onto the housing to be installed. This replaces manual labor, reduces labor costs, and expands the rubber ring from multiple angles. To avoid unevenness during assembly and ensure a tight connection between the rubber ring and the connector, the process involves the following steps: When gripping the rubber ring on the rubber ring guide block 2, the cylinder 15 controls the relative movement of gripper 11 and gripper 22, i.e., moving them away from each other. At this point, the slotted electric cylinder 24 moves the gripping unit downwards, positioning gripper 11 and gripper 22 on either side of the bottom of the rubber ring. After the rubber ring pops out of the rubber ring guide block 2, it enters the rubber ring guide groove 23. Gripper 11 and gripper 22 expand the rubber ring, and under the control of the electric cylinder 24, the rubber ring is moved... The simultaneous upward movement achieves the gripping effect on the rubber ring. The structure of gripper 11 and gripper 212 is set as a plate, and there are two protrusions on the inner side of the plate to support the inner side of the rubber ring. The gaps are left between the intermittent rubber ring shaping blocks 2 on the lower fixture base plate 1, and holes are drilled in the lower fixture base plate 1. The spring-loaded pin is placed in the hole and installed at the same time. When gripper 11 and gripper 212 move to both sides of the rubber ring, the spring-loaded pin is lifted by the external cylinder 15 and pushes the rubber ring up and down, so that it falls into the rubber ring shaping groove 23 in the upper fixture base plate 4.

[0063] Finally, after the rubber ring is gripped and expanded by the first gripper 11 and the second gripper 12, the electric cylinder 24 moves the gripping unit, the pushing unit, and the upper fixture base plate 4 together to the top of the housing to be installed. Then, the electric cylinder 24 controls the gripping unit, the pushing unit, and the upper fixture base plate 4 to move down to the surface of the housing to be installed, so that the rubber ring is placed on the surface of the housing to be installed. Then, the slot cylinder 15 separates the first gripper 11 and the second gripper 12, so that the rubber ring is removed from the first gripper 11 and the second gripper 12. At this time, the bolt penetrating the middle of the support block 6 will push the rubber ring out of the upper fixture contour groove under the action of the spring 22, and let it hang down on the surface of the housing to be installed. Thus, the entire gripping and placement process of the rubber ring is completed, and it can wait for the next step of pressing.
