Description

Technical Field

[0001] This application relates to the technical field of automated mechanical assembly, and in particular to a sealing ring press-in machine. Background Technology

[0002] In industries such as machinery manufacturing, automotive, electronics, and home appliances, the installation of sealing rings is a crucial step in ensuring the sealing performance of equipment. Sealing rings are primarily used to prevent liquid or gas leakage and also serve functions such as shock absorption and dust prevention.

[0003] Traditional sealing ring installation methods include manual installation and semi-automatic pressing-in methods. In manual installation, operators use simple tools such as pressure bars, rubber hammers, or manual clamps to press the sealing ring into the sealing groove of the mold. The semi-automatic pressing-in method uses pneumatic or hydraulically driven semi-automatic equipment, which provides pressure through cylinders and uses simple molds for positioning, and uses pressure blocks to press the sealing ring into the sealing groove of the mold.

[0004] Regarding the aforementioned technologies, manual installation is limited by the force and precision of manual operation, easily leading to uneven pressure distribution. This can cause problems such as seal deformation, localized wear, or improper installation, ultimately posing a risk of seal failure. Semi-automatic pressing methods, on the other hand, often use fixed cylinders, lacking the ability to adjust their position. When faced with multi-position or irregularly installed sealing grooves, the fixed cylinder structure cannot flexibly adapt to different working conditions, necessitating manual reinstallation in some scenarios. Existing seal installation technologies, due to multiple limitations in efficiency, precision, and flexibility, struggle to meet the demands of modern industry for high-efficiency production. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, one of the purposes of this utility model is to provide a sealing ring pressing machine.

[0006] This application provides a sealing ring pressing machine, which adopts the following technical solution:

[0007] A sealing ring pressing machine includes a frame, a cylinder, a base, a fixing plate, and a pressing block. The frame is fixedly mounted on the fixing plate, the base is slidably mounted on the frame, the cylinder is fixedly mounted on the base, and the piston rod of the cylinder is connected to the pressing block, which is located directly above the sealing groove of the mold.

[0008] By adopting the above technical solution, it is ensured that the base and cylinder can slide on the top of the frame. When facing multi-position sealing grooves or irregularly installed sealing grooves, the operator can change the position of the cylinder by moving the base and adjust the pressing position of the pressure block according to actual needs, ensuring that the pressure block is always directly above the sealing groove, ensuring that the sealing ring can be accurately pressed into the sealing groove. At the same time, it makes the pressing process uniform and precise in positioning, effectively avoiding problems such as displacement and twisting of the sealing ring during the pressing process, ensuring sealing performance, and improving product quality and production efficiency.

[0009] Preferably, the frame includes two first slide rails and a support structure. The support structure is installed on a fixed plate and connected to the bottom of the two first slide rails. The bottom of the seat is provided with a first slide groove, and the seat is slidably assembled to the two first slide rails through the first slide groove.

[0010] By adopting the above technical solution, the assembly method of slide rail and slide groove provides a stable sliding path for the seat. The operator pushes the seat to slide along the first slide rail, realizing the horizontal movement of the seat and cylinder, so that the pressure block is always located directly above the sealing groove, ensuring that the sealing ring can be pressed into the sealing groove of the mold.

[0011] Preferably, the base body is provided with first fixing bolts at both ends, the first fixing bolts pass through the base body and abut against the corresponding first slide rail.

[0012] By adopting the above technical solution, when the seat body moves to directly above the sealing ring, the seat body and the cylinder are fixed by the first fixing bolt, ensuring that the cylinder will not slip during the pressing process, and realizing the precise and stable pressing operation of the sealing ring into the sealing groove in the multi-position sealing groove or the sealing groove in the irregular installation space.

[0013] Preferably, the support structure includes four first support rods and four second support rods. The four first support rods are respectively fixed on the fixed plate. The first support rods are provided with two second sliding grooves inside. The second support rods are provided with two second sliding rails. The second sliding grooves are slidably assembled with the second sliding rails. The end of the second support rod away from the first support rod is fixedly installed on one end of the first sliding rail.

[0014] By adopting the above technical solution, when the height of the frame needs to be adjusted, the operator can do so by sliding the second support rod within the first slide rail. This height-adjustable frame can be adjusted according to molds of different heights, ensuring that the base and cylinder are at a suitable height, ensuring that the pressure block can always accurately press the sealing ring, thus guaranteeing product quality and production efficiency.

[0015] Preferably, the first support rod has a plurality of adjustment holes, which are evenly distributed along the length of the first support rod. The end of the second support rod connected to the first support rod has a positioning hole, and the bolt passes through both the adjustment hole and the positioning hole.

[0016] By adopting the above technical solution, when the frame height adjustment is completed, the operator aligns the positioning hole of the second support rod with the corresponding adjustment hole of the first support rod, and then uses bolts to pass through the positioning hole and the adjustment hole to fix the second support rod and the first support rod together, ensuring that the connection between the first support rod and the second support rod is more secure.

[0017] Preferably, the base has two guide holes, which are symmetrically distributed on both sides of the cylinder. A linear bearing is installed in each of the two guide holes. The pressure block has two insertion slots corresponding to the positions of the two guide holes. The positions of the insertion slots are strictly aligned with the axis of the linear bearing on the base. Each of the two insertion slots is connected to a limit rod, and each of the two limit rods passes through the linear bearing.

[0018] By adopting the above technical solution, the cooperation between the limiting rod and the linear bearing constrains the movement trajectory of the pressure block, making it only able to move in a straight line along the vertical direction. This effectively avoids the pressure block tilting or deviating during the movement, ensuring that the pressure block can act vertically and accurately on the sealing ring, and ensuring that the sealing ring is pressed evenly and stably into the sealing groove of the mold, thereby improving the sealing performance and product quality.

[0019] Preferably, two fastening blocks are provided above the fixing plate, the fastening blocks have protrusions at the bottom, the fixing plate has a third sliding groove, the fastening blocks are slidably assembled on the third sliding groove through the protrusions, and the fastening blocks are provided with a second fixing bolt, the second fixing bolt passes through the fastening block and abuts against the fixing plate.

[0020] By adopting the above technical solution, the two fastening blocks set above the fixed plate have protrusions at the bottom that cooperate with the third sliding groove on the fixed plate to form a sliding structure. This allows the operator to adjust the distance between the two fastening blocks according to the size of the mold to clamp molds of different specifications. After the two fastening blocks clamp the mold, the two fastening blocks are fixed with the second fixing bolt, which effectively prevents the mold from shifting or shaking during the sealing ring pressing process, ensuring the stability and accuracy of the pressing operation.

[0021] Preferably, the length direction of the third groove is perpendicular to the length direction of the first groove.

[0022] By adopting the above technical solution, the base and cylinder can move in the direction of the first slide groove, thereby driving the pressure block to move in the direction of the first slide groove. The fastening block can move on the third slide groove to clamp the mold, thus ensuring that the mold moves in the direction of the third slide groove. The perpendicular layout of the third slide groove to the first slide groove indirectly enables the base and cylinder to accurately position the mold in a plane and perform the sealing ring pressing operation, effectively improving the versatility of the equipment.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. It ensures that the base and cylinder can slide on the top of the frame. When facing multi-position sealing grooves or irregularly installed sealing grooves, the operator can move the base to change the position of the cylinder and adjust the pressing position of the pressure block according to actual needs. This ensures that the pressure block is always directly above the sealing groove, guaranteeing that the sealing ring can be accurately pressed into the sealing groove. At the same time, it makes the pressing process uniform and precise in positioning, effectively avoiding problems such as displacement and twisting of the sealing ring during the pressing process, ensuring sealing performance, and improving product quality and production efficiency.

[0025] 2. The assembly method of the slide rail and slide groove provides a stable sliding path for the seat. The operator pushes the seat along the first slide rail to move the seat and cylinder horizontally, so that the pressure block is always located directly above the sealing groove, ensuring that the sealing ring can be pressed into the sealing groove of the mold.

[0026] 3. When the frame height needs to be adjusted, the operator can do so by sliding the second support rod within the first slide rail. This height-adjustable frame can be adjusted according to molds of different heights, ensuring that the base and cylinder are at a suitable height, ensuring that the pressure block can always accurately press the sealing ring, thus guaranteeing product quality and production efficiency.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.

[0031] This application discloses a sealing ring pressing machine.

[0032] Reference Figure 1 and Figure 2 A sealing ring pressing machine includes a frame 1, a cylinder 2, a base 3, a fixed plate 4, and a pressing block 5. The frame 1 is fixedly connected to the fixed plate 4. The base 3 is slidably mounted on the top of the frame 1. The cylinder 2 is fixedly mounted on the base 3. The piston rod of the cylinder 2 passes through the base 3 and is connected to the top of the pressing block 5. A mold 02 is placed above the fixed plate 4. The sealing ring is placed in the sealing groove 01 of the mold 02, and the pressing block 5 is located directly above the sealing groove 01. The operator places the mold 02 on the fixed plate 4, then moves the base 3 and the cylinder 2, moving the cylinder 2 and the pressing block 5 directly above the sealing groove 01 to ensure that the sealing ring can be accurately pressed into the sealing groove 01, so that the sealing ring can be pressed smoothly into the sealing groove 01, and to ensure that the force is evenly distributed during the pressing process.

[0033] The frame 1 includes two first slide rails 101 and a support structure. The two first slide rails 101 are parallel, and the support structure is connected to the bottom of the two first slide rails 101. The bottom of the seat 3 is provided with a first slide groove 6. Preferably, in this embodiment, the first slide groove 6 is a dovetail groove. The seat 3 is slidably assembled to the two first slide rails 101 through the first slide groove 6. The two ends of the seat 3 are provided with first fixing bolts 7. The first fixing bolts 7 pass through the seat 3 and abut against the two slide rails. When facing a multi-position sealing groove 01 or a sealing groove 01 with an irregular installation space, the seat 3 and the cylinder 2 can achieve the alignment of the sealing ring and the pressure block 5 through the sliding cooperation of the first slide groove 6 and the first slide rail 101. After adjusting to a suitable position, the relative position of the seat 3 and the frame 1 is fixed by the first fixing bolts 7, thereby fixing the cylinder 2 relative to the frame 1, so as to realize the sealing ring pressing operation for the multi-position sealing groove 01 or the sealing groove 01 with an irregular installation space.

[0034] The support structure includes four first support rods 102 and four second support rods 103. The four first support rods 102 are fixed to the fixed plate 4. The first support rods 102 are hollow. One end of the second support rod 103 is slidably fitted into the first support rod 102, and the other end of the second support rod 103 is fixedly installed on one end of the first slide rail 101. The first support rods 102 have several adjustment holes 10, which are evenly distributed along the length of the first support rod 102. The end of the second support rod 103 connected to the first support rod 102 has a positioning hole 11. Bolts pass through both the adjustment holes 10 of the first support rod 102 and the positioning holes 11 of the second support rod 103 to fix them together. By passing bolts through different adjustment holes 10, the height of the frame 1 can be freely adjusted, and the height of the cylinder 2 can be adjusted to adapt to the operating requirements of molds 02 of different heights.

[0035] Furthermore, the first support rod 102 is provided with two second sliding grooves 8 inside. Preferably, in this embodiment, the second sliding groove 8 is a dovetail groove. The second support rod 103 is provided with two second sliding rails 9. Through the sliding cooperation of the second sliding grooves 8 and the second sliding rails 9, the sliding between the first support rod 102 and the second support rod 103 is more stable.

The pressure block 5 has two insertion slots 14 corresponding to the positions of the two guide holes 12. The positions of the insertion slots 14 are strictly aligned with the axis of the linear bearings 13 on the base 3. The two insertion slots 14 are respectively connected to limit rods 15. The two limit rods 15 pass through the linear bearings 13 respectively. The limit rods 15 and the linear bearings 13 form a sliding fit, thereby ensuring that the limit rods 15 move axially and restricting the radial displacement of the limit rods 15.

[0037] A third sliding groove 16 is provided on the fixed plate 4. Preferably, in this embodiment, the third sliding groove 16 is a dovetail groove, and the length direction of the third sliding groove 16 is perpendicular to the length direction of the first sliding groove 6.

The fastening blocks 17 are slidably assembled into the third sliding groove 16 through the protrusion 18. A second fixing bolt 19 is provided on the fastening blocks 17. The second fixing bolt 19 passes through the fastening blocks 17 and abuts against the fixed plate 4. By using the two fastening blocks 17 to clamp inward, the mold 02 on the fixed plate 4 is fixed, preventing the mold 02 from shifting or falling off due to force during the pressing process of the sealing ring presser, and ensuring that the sealing ring can be accurately pressed into the sealing groove 01.

[0038] The implementation principle of this embodiment is as follows: During the operation of the sealing ring pressing machine, the height of the frame 1 is first determined and fixed by adjusting the relative positions of the first support rod 102 and the second support rod 103 according to the height of the mold 02. The mold 02 is placed above the fixed plate 4, and two fastening blocks 17 slide in the third slide groove 16 to clamp the mold 02 inward, and fix it with the second fixing bolt 19 to prevent the mold 02 from shifting. According to the position of the sealing groove 01, the first fixing bolts 7 at both ends of the seat 3 are loosened, and the seat 3 and the cylinder 2 are moved to a suitable position through the sliding engagement of the first slide groove 6 of the seat 3 and the first slide rail 101 of the frame 1, so that the pressing block 5 is located directly above the sealing groove 01, and then the first fixing bolts 7 are tightened to fix the seat 3. Place the sealing ring in the sealing groove 01 of the mold 02, start the cylinder 2, the piston rod of the cylinder 2 drives the pressure block 5 to move downward, and at the same time the limit rod 15 moves axially under the restriction of the linear bearing 13 to ensure that the pressure block 5 presses down vertically, and accurately presses the sealing ring into the sealing groove 01, thus completing the pressing operation of the sealing ring.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
