Description

Technical Field

[0001] This utility model relates to the field of sealing component assembly technology, and in particular to a rubber sealing component positioning device with adjustable pressure distribution. Background Technology

[0002] When assembling seals, rubber seal positioning devices ensure that the seals are accurately placed and remain in a stable position. Because rubber seals are relatively soft and prone to deformation or displacement, positioning devices effectively prevent these problems, ensuring full contact between the seal and the assembly surface, thereby achieving the best sealing effect.

[0003] As shown in the reference case "Rubber Seal Assembly Mechanism" announcement number "CN212826934U", the rubber seal assembly mechanism of this utility model can quickly and effectively install products, effectively avoid errors made by workers during installation, reduce the difficulty of operation for workers, and improve production efficiency. Although the above-mentioned application can complete the assembly by placing the seal in the placement hole and pressing the seal into the product through the die head, thereby reducing the probability of installation errors through mechanical and automated assembly, the seal material is usually relatively soft and the device cannot adjust the pressure distribution. When assembling the seal on products with uneven sealing groove depths, the seal is easily affected by uneven pressure, resulting in deformation or damage. Utility Model Content

[0004] Therefore, it is necessary to provide a rubber seal positioning device with adjustable pressure distribution to address the problem that the device cannot adjust the pressure distribution.

[0005] An adjustable pressure distribution rubber seal positioning device includes: a worktable and a support frame disposed on the surface of the worktable, wherein an electric push rod is disposed at the top of the support frame.

[0006] The assembly mechanism includes a slide plate slidably connected inside the support frame, a positioning component is provided below the slide plate, and an assembly component is provided between the positioning component and the slide plate.

[0007] In one embodiment, the assembly includes a housing fixedly connected to the lower surface of the slide plate, the housing having a first cylinder and a plurality of second cylinders disposed inside.

[0008] In one embodiment, a plurality of second cylinders are connected to a first cylinder, and the first cylinder is located at the middle position of the plurality of second cylinders.

[0009] In one embodiment, a first piston is slidably connected to the inner wall of the first cylinder, and a first spring is fixedly connected between the first piston and the inner bottom wall of the first cylinder.

[0010] In one embodiment, a second piston is slidably connected to the inner wall of the second cylinder, and a second spring is fixedly connected between the second piston and the inner top wall of the second cylinder.

[0011] In one embodiment, a drive rod is fixedly connected to the lower surface of the second piston, and the bottom end of the drive rod extends through the second cylinder and the outer shell and is fixedly connected to a molding block.

[0012] In one embodiment, two telescopic rods are fixedly connected between the positioning component and the lower surface of the slide plate, and the two telescopic rods are respectively disposed on both sides of the positioning component.

[0013] In one embodiment, the electric push rod is fixedly connected to the top of the support frame, and the drive end of the electric push rod is fixedly connected to the upper surface of the slide plate.

[0014] Beneficial effects 1. By setting up assembly components in conjunction with positioning components, automatic pressure adjustment is achieved, which can effectively adapt to changes in the depth of different sealing grooves, ensuring uniform stress on the sealing components, avoiding local overpressure or stress concentration, and reducing the risk of deformation and damage. This not only improves the accuracy of assembly and sealing performance, but also extends the service life of the sealing components and enhances the practicality of the device; 2. By setting multiple second cylinders to cooperate with the first cylinder, an effective buffering effect can be provided during the stamping and assembly of the seal. This can effectively disperse the pressure applied to the seal, avoid excessive impact force from damaging the seal, and thus reduce the risk of seal deformation or damage.

[0023] The following is combined with Figures 1-4 This invention describes a rubber seal positioning device with adjustable pressure distribution.

[0024] In one embodiment, the rubber seal positioning device with adjustable pressure distribution includes: a worktable 100, a support frame 200 disposed on the surface of the worktable 100, and an electric push rod 210 disposed at the top of the support frame 200.

[0025] The assembly mechanism 300 includes a slide plate 310 slidably connected inside the support frame 200, a positioning component 340 is provided below the slide plate 310, and an assembly component 330 is provided between the positioning component 340 and the slide plate 310.

[0026] The positioning component 340 consists of a support base and a slider slidably connected to the inner wall of the support base. The slider has a positioning hole in the middle for placing the seal. The positioning hole is stepped. The support base also has a round hole in the middle that mates with the positioning hole. The shapes of the positioning hole and the round hole are matched with multiple molding blocks 335. Before assembling the seal, the seal is placed in the positioning hole, and then the slider is pulled to align the positioning hole with the round hole, thus completing the positioning of the seal. When the molding block 335 applies pressure to the seal, the seal, being made of rubber, is pressed from the positioning hole to the positioning groove of the product by the molding block 335. Then, through the continuous pressure of the molding block 335, the seal is stamped into a sealing ring that fits with the sealing groove.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the assembly component 330 includes a housing 331 fixedly connected to the lower surface of the slide plate 310. Inside the housing 331 are a first cylinder 332 and multiple second cylinders 333. All the second cylinders 333 communicate with the first cylinder 332, which is positioned at the center of the second cylinders 333. A first piston 3321 is slidably connected to the inner wall of the first cylinder 332, and a first spring 3322 is fixedly connected between the first piston 3321 and the inner bottom wall of the first cylinder 332. A second piston 3331 is slidably connected to the inner wall of the second cylinder 333, and a second spring 3332 is fixedly connected between the second piston 3331 and the inner top wall of the second cylinder 333. A drive rod 334 is fixedly connected to the lower surface of the second piston 3331, and the bottom end of the drive rod 334 extends through the second cylinder 333 and the housing 331 and is fixedly connected to a molding block 335.

[0028] In this embodiment, the support frame 200 consists of two support rods disposed on both sides of the workbench 100 and a support plate fixedly connected to the top of the support rods. The electric push rod 210 is mounted on the support plate. The pressure distribution during the seal assembly process can be precisely adjusted using hydraulic oil in multiple cylinders. During assembly, the housing drives multiple second cylinders 333 to move downwards synchronously, and multiple drive blocks apply pressure to the seal in a ring shape, pressing the seal into a sealing ring that fits against the bottom of the sealing groove. When the sealing groove depth is the same, the pressure on the multiple drive blocks is the same, and the multiple second pistons 3331 move synchronously, simultaneously compressing the hydraulic oil in the second cylinders 333 and pushing it into the middle first cylinder 332. Adjustment of the first cylinder 332 ensures uniform pressure within the multiple second cylinders 333. When the sealing groove depth is different, the forming block 335 corresponding to the shallower sealing groove experiences greater pressure, and the corresponding drive block pushes the second piston 3331 upwards via the drive rod 334, pushing more hydraulic oil into the first cylinder 332. At this time, the second cylinder 333 with higher pressure will distribute the excess hydraulic oil evenly to the other cylinders through the first cylinder 332, ensuring that all forming blocks 335 are subjected to the same pressure. After a single stamping is completed, the electric push rod 210 drives the assembly mechanism 300 to move upward. At this time, the pressure applied by the forming block 335 to the second piston 3331 is reduced, the pressure in the second cylinder 333 is reduced, and the second spring 3332 pushes the second piston 3331 to reset. At this time, the pressure in the first cylinder 332 is much greater than that in the other second cylinders 333. The hydraulic oil inside it will push the first piston 3321 under the action of the first spring 3322 to evenly press the hydraulic oil into multiple second cylinders 333 to complete the reset. It should be noted that the assembly mechanism 300 of this device achieves its effect only by changing the connection between the die head and the slide plate 310, and will not interfere with components other than the die head. Therefore, the assembly mechanism 300 of this device will not affect the normal installation of other components of the device. At the same time, this device only provides pressure distribution when the die head stamps the seal, and will not affect the normal operation of the device. In summary, the assembly mechanism 300 of this device will not affect the normal positioning and operation of the device.

[0029] like Figure 1 and Figure 2 As shown, two telescopic rods 320 are fixedly connected between the positioning component 340 and the lower surface of the slide plate 310, and the two telescopic rods 320 are respectively disposed on both sides of the positioning component 340. The electric push rod 210 is fixedly connected to the top of the support frame 200, and the drive end of the electric push rod 210 is fixedly connected to the upper surface of the slide plate 310.

[0030] In this embodiment, the telescopic rod 320 consists of a fixed rod fixedly connected to the lower surface of the slide plate 310, a sliding rod slidably connected to the inner wall of the fixed rod, and a telescopic spring disposed between the two sliding rods and the fixed rod. When the positioning component 340 moves to the surface of the product, the drive block needs to continue to descend. At this time, the positioning component 340 needs to remain stationary, so the telescopic rod 320 begins to retract, causing the drive block to press the seal inside the positioning component 340 into the product.

[0031] Working principle: The product is fixedly installed on the workbench 100, and then the seal is placed in the preset position through the positioning component 340. Then the electric push rod 210 is manually started. The drive end of the electric push rod 210 pushes the slide plate 310 to move downward. The slide plate 310 synchronously drives the assembly mechanism 300 to descend. When the positioning component 340 descends to contact the product, the positioning component 340 will stop moving. At this time, the slide plate 310 continues to drive the assembly component 330 to descend and compress the telescopic rod 320 until the molding block 335 molds the seal and presses the seal into the sealing groove of the product. During this process, the electric push rod 210 pushes the assembly component 330 down, and the forming block 335 matches the shape of the sealing groove, pressing the seal from the positioning component 340 into the sealing groove. After the forming block 335 enters the sealing groove, the electric push rod 210 continues to push the slide plate 310 downward. At this time, the forming block 335 applies an upward thrust to the second piston 3331 through the drive rod 334. When the sealing groove depth of the product is uniform, multiple forming blocks 335 will drive multiple second pistons 3331 to move synchronously through the drive rod 334, so that the pressure of multiple second cylinders 333 on the forming block 335 is the same. When the sealing groove depth is not uniform, different drive blocks push the second piston 3331 to move in the second cylinder 333 through the drive rod 334 according to the sealing groove depth. Through the adjustment of the first cylinder 332, the pressure in multiple second cylinders 333 is made uniform, thereby applying the same pressure to multiple forming blocks 335, so that the pressure on each part of the seal is uniform.

[0032] It should be noted that the electric push rod 210, the positioning component 340, the first spring 3322, the second spring 3332, and the telescopic rod 320 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the electric push rod 210 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
