Description

Technical Field

[0001] This utility model belongs to the field of sealing ring assembly technology, specifically relating to a piston sealing ring assembly machine. Background Technology

[0002] In the production process of automotive connectors, sealing rings need to be installed on the connectors. There may be situations where the shape of the sealing ring and the connector does not match. For example, the material of the sealing ring is mostly round, while the shape of the connector is mostly square. Therefore, in the connector production process, the sealing ring needs to be stretched open before assembly.

[0003] This invention relates to a sealing ring assembly machine disclosed in patent number CN219725189U, comprising a mounting plate, a spreading mechanism, a vertical moving mechanism, and a clamping mechanism. A base is fixedly connected to the bottom of the mounting plate, and a mounting column is fixedly connected to the top surface of the mounting plate. Through the arrangement of the spreading mechanism, vertical moving mechanism, and clamping mechanism, in use, the sealing ring to be spread is placed on the arc groove on the spreading column. Then, the controller controls a dual-axis servo motor to rotate in the reverse direction, driving the spreading column to spread the sealing ring along the groove. After spreading, the clamping mechanism fixes the connector to be installed with the sealing ring. Next, the servo motor on the vertical moving mechanism moves the connector to be installed with the sealing ring into the interior of the spread sealing ring. Subsequently, the dual-axis servo motor rotates forward to loosen the sealing ring, and finally, assembly is performed immediately, eliminating the need to consider the sealing ring retraction, thus improving assembly efficiency.

[0004] However, when the sealing ring assembly machine provided by the above patent is in use, the sealing ring is opened by the opening column. After the clamping mechanism drives the connector to contact the sealing ring, although the opening column retracts to make the sealing ring fit onto the connector, the sealing ring fits onto the arc groove on the opening column. The arc groove makes it impossible for the sealing ring to separate from the opening column on its own. It requires assistance to separate the sealing ring from the opening column, so the assembly efficiency of the sealing ring needs to be improved.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a piston seal ring assembly machine, which can solve the problem that the seal ring is difficult to separate from the expansion column after assembly.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows: A piston seal assembly machine, comprising: The ring support assembly includes a mounting shell. A cross-shaped groove is formed on the upper wall of the mounting shell. A first dual-axis lead screw and a second dual-axis lead screw are installed inside the mounting shell. Moving blocks are threaded onto the positive and negative threads of the first and second dual-axis lead screws, respectively. When the first and second dual-axis lead screws rotate, they drive the moving blocks on the corresponding positive and negative threads to move closer to or further apart from each other. A spreading column is fixedly connected to each moving block. The movement of the moving block drives the spreading column to move, thereby causing the four spreading columns to move closer to or further apart from each other through the rotation of the first and second dual-axis lead screws. This allows the sealing ring to be opened and retracted through the spreading columns, facilitating the installation of the sealing ring. The upper end of the expansion column near the center of the mounting housing is set as a wedge-shaped part. When the expansion column expands the sealing ring to facilitate its fitting onto the connector, as the connector moves upward, the distance between the expansion columns can be gradually adjusted to be smaller as the electrical connection moves upward, so that the sealing ring continues to retract, thereby making the sealing ring and the connector secure. Then the connector can drive the sealing ring to move upward, making it easy for the sealing ring and the expansion column to separate.

[0008] The mating ring assembly includes a connecting block with a slider slidably connected within it, allowing the slider to move up and down within the block. A mounting bracket is fixedly connected to the bottom of the slider at one end of the connecting block; movement of the slider moves the mounting bracket. Clamping mechanisms are installed on both the front and rear side panels of the mounting bracket, securing the connector. L-shaped push rods are rotatably connected to the bottom of both the front and rear side panels of the mounting bracket, allowing the L-shaped push rods to rotate at the bottom of the mounting bracket. Simultaneously, the up and down movement of the mounting bracket moves the L-shaped push rods up and down. When the sealing ring, opened by the expansion post, is fitted onto the connector, rotation positions the bottom panel of the L-shaped push rod at the bottom of the sealing ring. When the mounting bracket moves upward, the bottom of the L-shaped push rod pushes the sealing ring upward, disengaging it from the expansion post and improving the assembly efficiency of the sealing ring.

[0009] In one or more embodiments of this utility model, the first dual-axis lead screw and the second dual-axis lead screw are arranged in a cross-shaped staggered manner, and the first dual-axis lead screw and the second dual-axis lead screw are arranged directly below the cross-shaped slide groove, so that the supporting column on the first dual-axis lead screw and the second dual-axis lead screw can move through the cross-shaped slide groove.

[0010] In one or more embodiments of this utility model, a first bevel gear is installed at the center of the first dual-axis lead screw, and a second bevel gear is installed at the center of the second dual-axis lead screw. The first bevel gear and the second bevel gear are meshed together. Therefore, in use, the first dual-axis lead screw and the second dual-axis lead screw can be driven to rotate through the connection of the first bevel gear and the second bevel gear.

[0011] In one or more embodiments of this utility model, the side wall of the expanding column away from the wedge-shaped part is rounded, so that the side wall of the expanding column away from the wedge-shaped part is an arc-shaped surface, so that the surface in contact with the sealing ring and the expanding column is arc-shaped, so that the resistance between the sealing ring and the expanding column is small, thus making it easy for the sealing ring and the expanding column to separate.

[0012] In one or more embodiments of this utility model, a sliding groove is provided in the connecting block, and the slider is slidably connected in the sliding groove, so that the slider slides up and down in the connecting block through the sliding groove.

[0013] In one or more embodiments of this utility model, the sliding groove is rotatably connected to a screw in an up-down arrangement, and the slider is threadedly connected to the screw. The slider can be driven to move up and down by rotating the screw.

[0014] In one or more embodiments of the present invention, the clamping mechanism includes a mounting plate, which is fixedly connected to the front and rear walls of the mounting frame.

[0015] In one or more embodiments of this utility model, an electro-hydraulic actuator is mounted on the mounting plate, and a clamping plate is mounted on the driving end of the electro-hydraulic actuator. The connector is fixed by moving the clamping plate through the electro-hydraulic actuator.

[0016] In one or more embodiments of this utility model, the clamps on the front and rear end plates of the mounting bracket are arranged in a relative manner, and the opposite side walls of the clamps are provided with arc-shaped grooves, so that the clamps can stably fix the connector.

[0017] In one or more embodiments of this utility model, the bottom of the front and rear wall panels of the mounting bracket are rotatably connected to a rotating shaft, and the upper end of the L-shaped push rod is fixedly connected to the bottom of the rotating shaft. The L-shaped push rod can be driven to rotate at the bottom of the mounting bracket by the rotation of the rotating shaft.

[0018] Compared with the prior art, this utility model improves the shape of the expansion column. When the expanded sealing ring is fitted onto the connector, the connector moves upward and simultaneously reduces the distance between the expansion columns, making the sealing ring and the connector tight. At the same time, when the L-shaped push rod moves upward, it pushes the sealing ring upward, which makes it easier for the connector to drive the sealing ring to detach from the expansion column, thus improving the assembly efficiency of the sealing ring.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0023] like Figures 1-3 As shown, a piston seal ring assembly machine according to one embodiment of the present invention includes a support ring assembly 1 and a mating ring assembly 2.

[0024] like Figures 1-4As shown, the support ring assembly 1 includes a mounting shell 11. A cross-shaped groove 12 is provided on the upper wall of the mounting shell 11. A first dual-axis lead screw 13 and a second dual-axis lead screw 14 are installed inside the mounting shell 11. Moving blocks 17 are threaded onto the positive and negative threads of the first dual-axis lead screw 13 and the second dual-axis lead screw 14, respectively. When the first dual-axis lead screw 13 and the second dual-axis lead screw 14 rotate, they can drive the moving blocks 17 on the corresponding positive and negative threads to move closer to or further away from each other. A spreading column 18 is fixedly connected to the moving block 17. The movement of the moving block 17 can drive the spreading column 18 to move. Thus, the rotation of the first dual-axis lead screw 13 and the second dual-axis lead screw 14 can drive the four spreading columns 18 to move closer to or further away from each other, so that the spreading columns 18 can open and retract the sealing ring, making the installation of the sealing ring convenient. The upper end of the side wall near the center of the mounting housing 11 of the expansion post 18 is set as a wedge-shaped part 19. When the expansion post 18 expands the sealing ring to facilitate its fitting onto the connector, as the connector moves upward, the distance between the expansion posts 18 can be gradually adjusted to be smaller as the electrical connection moves upward under the action of the wedge part 19, so that the sealing ring continues to retract, thereby making the sealing ring and the connector secure. Then the connector can drive the sealing ring to move upward, making it easy for the sealing ring and the expansion post 18 to separate.

[0025] like Figures 2-4 As shown, the first dual-axis lead screw 13 and the second dual-axis lead screw 14 are arranged in a cross shape, alternating vertically. The first dual-axis lead screw 13 and the second dual-axis lead screw 14 are located directly below the cross-shaped slide groove 12, so that the supporting column 18 on the first dual-axis lead screw 13 and the second dual-axis lead screw 14 can move through the cross-shaped slide groove 12.

[0026] like Figure 4 As shown, a first bevel gear 15 is installed at the center of the first dual-axis lead screw 13, and a second bevel gear 16 is installed at the center of the second dual-axis lead screw 14. The first bevel gear 15 and the second bevel gear 16 are meshed together. Therefore, when in use, the first dual-axis lead screw 13 and the second dual-axis lead screw 14 can be driven to rotate through the connection of the first bevel gear 15 and the second bevel gear 16.

[0027] like Figure 4 As shown, the side wall of the support column 18 away from the wedge-shaped part 19 is rounded, so that the side wall of the support column 18 away from the wedge-shaped part 19 is an arc-shaped surface. This makes the surface of the sealing ring in contact with the support column 18 arc-shaped, which reduces the resistance between the sealing ring and the support column 18, thus making it easier for the sealing ring to separate from the support column 18.

[0028] like Figures 1-3 as well as Figure 5As shown, the mating ring assembly 2 includes a connecting block 21, with a slider 24 slidably connected within the connecting block 21, allowing the slider 24 to move up and down within the connecting block 21. A mounting bracket 25 is fixedly connected to the bottom of one of the outer ends of the slider 24, and the movement of the slider 24 drives the mounting bracket 25 to move. Clamping mechanisms are installed on both the front and rear side panels of the mounting bracket 25, which can be used to fix the connector. L-shaped push rods 29 are rotatably connected to the bottom of both the front and rear side panels of the mounting bracket 25, allowing the L-shaped push rods 29 to rotate at the bottom of the mounting bracket 25. Simultaneously, the up and down movement of the mounting bracket 25 drives the L-shaped push rods 29 to move up and down. When the sealing ring, opened by the supporting column 18, is fitted onto the connector, rotation causes the bottom panel of the L-shaped push rod 29 to be located at the bottom of the sealing ring. When the mounting bracket 25 moves upward, the bottom of the L-shaped push rod 29 pushes the sealing ring upward, causing the sealing ring to disengage from the supporting column 18, thereby improving the assembly efficiency of the sealing ring.

[0029] like Figure 5 As shown, a sliding groove 22 is provided in the connecting block 21, and the slider 24 is slidably connected in the sliding groove 22, so that the slider 24 slides up and down in the connecting block 21 through the sliding groove 22.

[0030] like Figure 5 As shown, the sliding groove 22 is rotatably connected to the screw 23 in an up-down configuration, and the slider 24 is threaded onto the screw 23. The slider 24 can be driven to move up and down by rotating the screw 23.

[0031] like Figures 1-3 As shown, the clamping mechanism includes a mounting plate 26, which is fixedly connected to the front and rear walls of the mounting frame 25.

[0032] like Figures 1-3 As shown, an electro-hydraulic actuator 27 is mounted on the mounting plate 26, and a clamping plate 28 is mounted on the driving end of the electro-hydraulic actuator 27. The connector is fixed by moving the clamping plate 28 driven by the electro-hydraulic actuator 27.

[0033] like Figures 1-3 As shown, the clamping plates 28 on the front and rear end plates of the mounting bracket 25 are arranged in a relative manner, and the opposite side walls of the clamping plates 28 are provided with arc-shaped grooves, so that the clamping plates 28 can stably fix the connector.

[0034] like Figure 1 and Figure 5 As shown, the bottom of the front and rear wall panels of the mounting bracket 25 are rotatably connected to a rotating shaft 210. The upper end of the L-shaped push rod 29 is fixedly connected to the bottom of the rotating shaft 210. The rotation of the rotating shaft 210 can drive the L-shaped push rod 29 to rotate at the bottom of the mounting bracket 25.

[0035] It should be noted that, since a first bevel gear 15 and a second bevel gear 16 are provided between the first dual-axis lead screw 13 and the second dual-axis lead screw 14, by installing a motor to drive the first dual-axis lead screw 13 or the second dual-axis lead screw 14 to rotate, the first dual-axis lead screw 13 and the second dual-axis lead screw 14 can rotate synchronously. This causes the four expansion columns 18 to move synchronously when the first dual-axis lead screw 13 and the second dual-axis lead screw 14 rotate, thereby improving the effect of the expansion columns 18 on the opening and retraction of the sealing ring. The connection between the motor and the first dual-axis lead screw 13 or the second dual-axis lead screw 14, as well as the rotation of the screw 23 driven by the motor, are existing technologies and will not be described in detail here.

[0036] In use, the rotation of the first dual-axis lead screw 13 and the second dual-axis lead screw 14 causes the four expansion columns 18 to retract together. Then, the sealing ring is fitted onto the four expansion columns 18. The first dual-axis lead screw 13 and the second dual-axis lead screw 14 drive the expansion columns 18 to move, thus opening the sealing ring. The connector is then clamped and fixed by the clamping mechanism. The slider 24 drives the mounting bracket 25 to move downward, thereby moving the connector downward. When the connector is between the four expansion columns 18, the sealing ring is fitted onto the connector. By rotating the L-shaped push rod 29, its bottom wall plate is positioned below the sealing ring. Then, the retraction of the expansion columns 18 causes the sealing ring to retract, so that the sealing ring contacts the connector. As the expansion columns 18 continue to retract, the connector slowly moves upward, gradually tightening the seal between the sealing ring and the connector. At the same time, as the L-shaped push rod 29 moves upward, it pushes the sealing ring upward, making it easier for the sealing ring to disengage from the expansion columns 18, so that the sealing ring can be assembled onto the connector, improving the efficiency of sealing ring assembly.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. 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. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
