Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automation equipment, in particular to a rubber gasket assembling mechanism. BACKGROUND

[0002] At present, rubber gaskets need to be arranged in control boxes to play a role of buffering and sealing. Generally, mounting holes for rubber gaskets are arranged on the control boxes to insert rubber gaskets. The special structure design of rubber gaskets makes them have a middle annular step, so that the diameters of the upper and lower ends are obviously larger than the diameter of the middle part. This structural feature brings great difficulty to the assembling process. On the one hand, in order to ensure the stability after assembling, the width of the mounting hole of the box body must be smaller than the maximum outer diameter of the rubber gasket; on the other hand, the size difference forces a large external force to be applied to make the rubber gasket deform to be squeezed into the mounting hole during assembling. The traditional manual assembling method not only has low efficiency, but also is prone to fatigue of the operator, and it is difficult to ensure the consistency of the assembling quality. Especially in the mass production environment, the disadvantages of manual assembling are more prominent, including slow assembling speed, high labor intensity, and difficult control of product qualification rate. In addition, different specifications of rubber gaskets require different assembling forces, which is difficult for manual operation to accurately grasp, and is prone to cause damage to the rubber gasket or improper assembling.

DETAILED DESCRIPTION

[0016] Combination Figs. 1 to 3 As shown, the embodiment provides a rubber ring assembly mechanism, which comprises a base 1, a straight sliding groove 11 is formed on the base 1, suitable for placing a rubber ring 4, one end of the straight sliding groove 11 is provided with a guide pre-pressing structure 2, the guide pre-pressing structure 2 is arranged at the opening of the end of the straight sliding groove 11, and a guide port 22 is formed for the rubber ring 4 to pass through; the guide port 22 is suitable for communicating with the mounting hole of the target box body, and the width of the guide port 22 is less than or equal to the width of the mounting hole; the other end of the straight sliding groove 11 is provided with a pushing device 3, which is suitable for pushing the rubber ring 4 placed in the straight sliding groove 11 to the guide pre-pressing structure 2, and deforming the rubber ring 4 at the guide pre-pressing structure 2 to pass through the guide port 22 and enter the mounting hole of the target box body.

[0017] Wherein, the straight sliding groove 11 refers to the groove structure extending along the surface of the base 1, used for accommodating and guiding the straight-line movement of the rubber ring 4, which can be realized by a rectangular or U-shaped cross-section groove body, and its length and width can be adjusted according to the size of the ring. The guide pre-pressing structure 2 refers to the limiting component arranged at the outlet of the sliding groove, which compresses and guides the ring through the guide port 22, for example, through the adjustable guide block 21 to form a variable opening guide channel, to ensure that the ring gradually deforms to the size that can pass through the mounting hole during movement. The pushing device 3 refers to the driving component that provides straight-line thrust, such as the structure of the cylinder combined with the pushing block 32, which smoothly pushes the ring into the guide pre-pressing area when the pushing block 32 moves along the sliding groove. After the rubber ring 4 is placed in the straight sliding groove 11, the pushing device 3 is started and drives the pushing block 32 to move along the sliding groove towards the guide pre-pressing structure 2. The ring slides along the sliding groove under the action of the pushing force, and when it reaches the guide port 22, it is extruded by the guide structure on both sides, and its outer diameter is compressed to be less than or equal to the width of the mounting hole, so as to smoothly pass through the guide port 22 and embed into the mounting hole of the target box body. The width limitation of the guide port 22 ensures that the ring completes the necessary deformation before entering the mounting hole, avoiding assembly failure due to size mismatch.

[0018] The scheme realizes the automatic alignment and controllable deformation of the gasket through the mechanical guide pre-pressing structure 2 and the pushing device 3, reduces manual intervention, and improves assembly accuracy and efficiency. The adjustable design of the guide port 22 further enhances the adaptability of the mechanism to gaskets of different sizes. The rapid and stable assembly of the rubber gasket 4 is realized, and the fatigue and errors caused by manual operation are avoided. The guide pre-pressing structure 2 ensures that the gasket completes accurate deformation before entering the mounting hole, and the pushing device 3 provides continuous and uniform pushing force, thereby significantly improving assembly efficiency and reducing defective rate. The mechanism is especially suitable for batch production scenes and can effectively solve the problems of slow speed and poor consistency in traditional assembly methods.

[0019] In this embodiment, the guide pre-pressing structure 2 includes two guide blocks 21 arranged on both sides of the opening of the linear sliding groove 11, and the positions of the guide blocks 21 on the base 1 are adjustable to adjust the opening of the guide port 22 formed between the two guide blocks 21 to adapt to rubber gaskets 4 of different outer diameters. The two guide blocks 21 extend into the part of the linear sliding groove 11 from the opposite sides of the linear sliding groove 11 to form the guide port 22. The guide block 21 refers to a limiting member arranged on both sides of the sliding groove opening, which can be realized by a sliding block structure with an adjusting bolt. By changing the fixed position of the sliding block on the base 1, the width of the guide port 22 can be controlled. The position-adjustable guide block 21 forms a movable connection relationship with the base 1, which can be realized by a sliding rail and a positioning hole, for example, a long strip-shaped sliding groove is arranged on the base 1 for the bottom of the guide block 21 to slide. The two guide blocks 21 are respectively installed on the two side edges of the opening at the end of the linear sliding groove 11. By adjusting the relative position of the guide blocks 21 along the length direction of the sliding groove, the width of the guide port 22 formed between the two guide blocks 21 can be changed. When assembling rubber gaskets 4 of different outer diameters, the guide blocks 21 can be moved to the corresponding position to match the width of the guide port 22 with the outer diameter of the target rubber gasket 4. Under the action of the pushing device 3, the rubber gasket 4 is compressed and deformed when passing through the guide port 22, and the deformation amount is accurately controlled by the width of the guide port 22, thereby ensuring smooth entry into the mounting hole. Through the movable guide block 21 structure, the size of the guide port 22 can be quickly adjusted without replacing parts, effectively solving the compatibility problem of multi-specification product assembly.

[0020] In a preferred embodiment, the guide opening 22 is arranged in an "eight" shape opening with gradually reduced opening degree along the movement direction of the rubber gasket 4. The guide opening 22 is realized by the gap between the two symmetrically distributed guide blocks 21, and the width of the gap gradually decreases along the movement direction of the rubber gasket 4, thereby guiding the rubber gasket 4 to gradually deform to adapt to the size of the mounting hole. The "eight" shape opening refers to a symmetric structure in which the gap between the two guide blocks 21 is wider at the entrance and narrower at the exit, which can be realized by adjusting the inclination angle or relative position of the guide blocks 21, or by setting the shape structure of the guide blocks 21. This structure can uniformly compress the rubber gasket 4 during movement, avoiding local stress concentration. When the pushing device 3 pushes the rubber gasket 4 along the straight slot 11 to the guide pre-pressing structure 2, the rubber gasket 4 first contacts the entrance end of the "eight" shape opening, at which time the opening degree is larger and the rubber gasket 4 begins to deform. With the continuous action of the pushing device 3, the rubber gasket 4 gradually enters the area with gradually reduced opening degree, and its outer diameter is squeezed by the two side guide blocks 21 until the deformed size matches the width of the mounting hole, and finally smoothly passes through the guide opening 22 into the mounting hole of the target box body. During this process, the gradual compression characteristics of the "eight" shape opening make the deformation process of the rubber gasket 4 more gentle, reducing the assembly resistance or gasket damage risk caused by sudden squeezing. By making the deformation process of the rubber gasket 4 complete in stages, both the assembly required pushing force and the deformation uniformity are improved.

[0021] In another preferred embodiment, a guide slope 211 is arranged on the top surface of the guide block 21, which is inclined from bottom to top along the movement direction of the rubber gasket 4. The guide slope 211 refers to the surface on the top surface that is inclined from bottom to top, which can be realized by a plane or a micro-arc surface, and the inclination angle can be, for example, between 10 degrees and 30 degrees, to guide the rubber gasket 4 to gradually deform and smoothly enter the mounting hole during compression, reducing the movement resistance. When the pushing device 3 pushes the rubber gasket 4 to the guide opening 22, the guide slope 211 contacts the rubber gasket 4, guiding it to gradually compress and deform in the movement direction, thereby smoothly passing through the guide opening 22 into the mounting hole. The slope design ensures a gentle deformation process, avoiding jamming or rebound phenomenon caused by sudden stress. For example, after the rubber gasket 4 contacts the guide slope 211, the larger diameter portions at the upper and lower ends of the rubber gasket 4 will gradually close along the slope until it passes through the guide opening 22 into the mounting hole. The slope design makes the compression deformation of the rubber gasket 4 progressive, reducing the assembly resistance and avoiding material damage caused by local stress concentration.

[0022] It should be noted that in this embodiment, the thickness of the guide block 21 is less than or equal to the height of the annular step of the rubber ring 4. The thickness of the guide block 21 is the dimension of the guide block 21 in the direction perpendicular to the extension direction of the straight sliding groove 11, and the thickness limit can ensure that the guide block 21 does not excessively interfere with the compression space of the annular step when guiding the deformation of the rubber ring 4. Among them, the height of the annular step of the rubber ring 4 refers to the depth of the middle concave area of the rubber ring 4 in the vertical direction, which determines the deformation amount of the rubber ring 4 when compressed and deformed. When the pushing device 3 pushes the rubber ring 4 along the straight sliding groove 11 to the guide pre-pressing structure 2, the annular step area of the rubber ring 4 will be deformed due to the extrusion of the guide port 22. This makes the rubber ring 4 maintain a stable deformation path when passing through the guide port 22, avoiding the annular step being accidentally blocked or stuck due to the excessive thickness of the guide block 21. Reducing the assembly failure rate and improving the efficiency of automatic assembly.

[0023] The pushing device 3 described in this embodiment includes a pushing cylinder 31 and a pushing block 32 connected to the output end of the pushing cylinder 31. The pushing block 32 is adapted to move linearly along the straight sliding groove 11 to push the rubber ring 4 to the guide port 22. The pushing block 32 is connected to the pushing cylinder 31 through a connecting block 34, and the connecting block 34 is provided with a clamping groove 341 for embedding the push rod in the pushing cylinder 31. The pushing block 32 and the connecting block 34 can be integrated.

[0024] Among them, the pushing cylinder 31 refers to an execution element that generates linear motion power through compressed air, and its output end is mechanically connected to the connecting block 34 through a push rod. The pushing block 32 refers to the pushing component that directly contacts the rubber ring 4, and the bottom shape can match the profile of the straight sliding groove 11. This structure can ensure that the rubber ring 4 maintains a predetermined posture during pushing, preventing deviation and causing uneven deformation. Among them, the clamping groove 341 refers to a mechanical interface provided on the connecting block 34, which can be implemented in a T-shaped groove structure, and the end of the push rod can be embedded and clamped. This design facilitates quick disassembly and maintenance, while ensuring the reliability of power transmission. When the pushing cylinder 31 is started, the push rod drives the connecting block 34 to move linearly through the clamping groove 341, and the pushing block 32 integrally formed with the connecting block 34 moves along the straight sliding groove 11. After the front end of the pushing block 32 contacts the rubber ring 4, it continuously applies a pushing force to make it slide to the guide pre-pressing structure 2.

[0025] In the preferred embodiment, a pushing guide structure 33 is provided above the straight sliding groove 11 to maintain the stability of the linear motion of the pushing block 32. The pushing guide structure 33 is detachably installed on the base 1 by bolts, and forms a movable guide space for the pushing block 32.

[0026] The pushing guide structure 33 refers to a limiting component arranged above the straight sliding groove 11 and corresponding to the movement track of the pushing block 32, which can be realized by a metal frame with a guide sliding groove 331, and the function is to limit the movement direction of the pushing block 32 by physical constraint to prevent deviation during pushing. A guide rib 321 is arranged on the top surface of the pushing block 32, and the inner side of the pushing guide structure 33 is formed with a guide sliding groove 331 matched with the guide rib 321. The guide rib 321 refers to a protruding structure extending along the movement direction of the pushing block 32, which can be realized by welding a metal strip with a trapezoidal cross section on the top surface of the pushing block 32, and the structure forms a stable sliding pair by cooperating with the guide sliding groove 331.

[0027] Specifically, during the assembly of the rubber gasket 4, when the pushing cylinder 31 drives the pushing block 32 to move along the straight sliding groove 11, the guide rib 321 is embedded in the guide sliding groove 331 to form a double guide mechanism. When the pushing block 32 bears the reaction force of the rubber gasket 4, the guide rib 321 disperses the lateral load through the contact surface between the guide rib 321 and the guide sliding groove 331, effectively avoiding the inclination or deviation of the pushing block 32 during movement. The length of the guide sliding groove 331 can be set to cover the full stroke of the pushing block 32 to ensure stable guidance during the critical stage of pre-pressing deformation of the rubber gasket 4.

[0028] Through the above technical solution, the application effectively solves the problem of movement track deviation of the pushing block 32 caused by uneven force during the pre-pressing assembly of the rubber gasket 4. The cooperation structure of the guide rib 321 and the guide sliding groove 331 improves the movement precision of the pushing block 32 in the straight sliding groove 11, increases the consistency of the deformation amount of the rubber gasket 4 during assembly, and avoids assembly failure or part damage caused by the inclination of the pushing block 32.

[0029] In the preferred embodiment, an optical fiber sensor 5 is arranged on one side of the base to detect whether there is a rubber gasket 4 in the straight sliding groove, to prevent empty operation.

[0030] Through the embodiment, the installation efficiency of the rubber gasket 4 is improved, and it is suitable for rubber gaskets 4 of various specifications and has good universality.

[0031] It should be understood that the above is only a preferred embodiment of the application, and the protection scope of the application is not limited to the above-mentioned embodiments. Any technical solution falling within the scope of the application is within the protection scope of the application.

[0032] The above description of the drawings used in the embodiments only shows some embodiments of the application and should not be considered as limiting the scope. For those skilled in the art, other related drawings can be obtained from the drawings without creative labor.
