[0029] 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.
[0030] Please see Figure 1 and Figure 2 This invention discloses an automatic assembly device for an embedded sealing ring of a rear shock absorber guide seat. The device includes a mechanical claw, which comprises a transfer component 1, a three-axis moving component. A connecting plate 11 is mounted on the output end of the transfer component 1. A fixed half-column 21 is fixedly mounted on the lower side of the connecting plate 11. A sliding half-column 22 is slidably mounted on the connecting plate 11. The sliding half-column 22 fits into the axial section of the fixed half-column 21. An accommodating arc groove 31 is formed near the lower end of the arc-shaped surfaces of the fixed half-column 21 and the sliding half-column 22. After the sliding half-column 22 slides, the two accommodating arc grooves 31 are coplanar. A driving cylinder 23 is fixedly mounted on the connecting plate 11, and the output end of the driving cylinder 23 is fixedly connected to the sliding half-column 22.
[0031] Specifically, the sliding half-pillar 22 is aligned with the fixed half-pillar 21 by the drive cylinder 23, and the two receiving arc grooves 31 are coplanar. The transfer component 1 drives the connecting plate 11 to slide, so that the sliding half-pillar 22 and the fixed half-pillar 21 are inserted into the sealing ring, and the sealing ring enters the receiving arc groove 31. The sliding half-pillar 22 is then misaligned with the fixed half-pillar 21 by the drive cylinder 23, which pulls on the sealing ring, causing the radial dimension of the sealing ring to decrease and enter the receiving arc groove 31. Subsequently, under the movement of the transfer component 1, the sliding half-pillar 22 and the fixed half-pillar 21 are inserted into the guide seat. The fixed half-pillar 21 stops at the annular groove position where the sealing ring is installed on the guide seat. The sliding half-pillar 22 slides under the drive of the drive cylinder 23, and the radial dimension of the sealing ring gradually recovers. After the radial dimension of the sealing ring increases, it enters the annular groove where the sealing ring is installed on the guide seat. The sealing ring is restricted by the axis of the annular groove. The sliding half-pillar 22 and the fixed half-pillar 21 are disengaged from the guide seat by the upward movement of the transfer component 1.
[0032] In this way, the sealing ring is gripped by the sliding half-pillar 22 and the fixed half-pillar 21. The structure is simple, easy to manufacture and maintain, and reduces the cost of equipment use.
[0033] To facilitate the supply of sealing rings and guide seats, existing technologies typically include a vibratory feeder, with the output end of the vibratory feeder connected to a belt conveyor or other conveying equipment. The transfer component 1 drives the mechanical claw to transfer the sealing rings between the two belt conveyors. These are all existing technologies and will not be described in detail here.
[0034] To facilitate component installation, an equipment mounting frame is provided. The transfer component 1 is a three-axis moving component, including an x-axis slide rail fixedly mounted on the equipment mounting frame, a fixed plate mounted on the x-axis slide rail, a z-axis slide rail mounted on the fixed plate, a fixed plate also mounted on the z-axis slide rail, a y-axis slide rail mounted on the fixed plate, and a connecting plate 11 fixedly mounted on the y-axis slide rail. The x-axis slide rail, z-axis slide rail, and y-axis slide rail are all connected to a drive component, which can be a linear drive mechanism such as a cylinder, electric actuator, or ball screw.
[0035] The connecting plate 11 is an L-shaped plate with through holes. Both the sliding half-pillar 22 and the fixed half-pillar 21 are installed within these through holes. Another L-shaped plate is fixedly connected to the connecting plate 11. The driving cylinder 23 is fixedly installed on the L-shaped plate and is selected as a pneumatic cylinder. After alignment with the fixed half-pillar 21, the sliding half-pillar 22 forms a cylindrical shape. The two accommodating arc grooves 31 are coplanar and annular. The diameters of the sliding half-pillar 22 and the fixed half-pillar 21, as well as the accommodating arc grooves 31, are set according to the sealing ring size and the guide seat inner diameter, allowing the sliding half-pillar 22 and the fixed half-pillar 21 to be inserted into the guide seat. In this embodiment, the diameters of the sliding half-pillar 22 and the fixed half-pillar 21 are the same as the guide seat inner diameter, and the diameter of the accommodating arc groove 31 is the same as the diameter of the sealing ring cross-section.
[0036] As a specific embodiment of the automatic assembly equipment for the embedded sealing ring of the rear shock absorber guide seat provided in the application, anti-extrusion grooves 32 are provided on both sides of the fixed half column 21. The lower side of the anti-extrusion groove 32 is connected to the accommodating arc groove 31. The side of the anti-extrusion groove 32 penetrates the axial section of the fixed half column 21. The side of the anti-extrusion groove 32 away from the axial section of the fixed half column 21 is an inclined surface from the upper side of the anti-extrusion groove 32 to the axial section of the fixed half column 21.
[0037] In specific application scenarios, when the sliding half-pillar 22 and the fixed half-pillar 21 insert the sealing ring into the guide seat, and during the downward movement of the sliding half-pillar 22, the sealing ring may be squeezed between the sliding half-pillar 22 or the fixed half-pillar 21 and the guide seat, causing the sealing ring to fail to reset properly. When the sliding half-pillar 22 and the fixed half-pillar 21 move upward, they may lift the guide seat, leading to installation failure and affecting the operation of the production line. An anti-squeezing groove 32 is provided on the sliding half-pillar 22. When the sliding half-pillar 22 moves upward and stretches the sealing ring, the sealing ring enters the anti-squeezing groove 32, preventing the sealing ring from being squeezed into the gap when the sliding half-pillar 22 and the fixed half-pillar 21 insert the sealing ring into the guide seat. When the sliding half-pillar 22 moves downward, the anti-squeezing groove 32 also provides space for the deformation of the sealing ring, further reducing the possibility of the sealing ring entering the gap and being squeezed.
[0038] Furthermore, both sides of the sliding half-column 22 are provided with inner grooves 33. The inner grooves 33 are located near the axial section of the sliding half-column 22 where the accommodating arc groove 31 is located, and the inner grooves 33 penetrate the axial section of the sliding half-column 22.
[0039] It should be understood that by setting the inner groove 33, the sealing ring located at the position of the sliding half column 22 is allowed to enter the inner groove 33, further reducing the possibility of the sealing ring being squeezed into the gap.
[0040] Furthermore, the connecting plate 11 is slidably mounted on the output end of the transfer component 1, and the output end of the transfer component 1 is fixedly mounted with the second drive 231, the output end of the second drive 231 being fixedly connected to the connecting plate 11.
[0041] It should be understood that during the installation of the sealing ring, after the sliding half-pillar 22 descends to be flush with the fixed half-pillar 21, the sliding half-pillar 22 and the fixed half-pillar 21 move downwards again as a whole during the second drive 231. If the portion of the sealing ring located in the anti-extrusion groove 32 after deformation does not smoothly enter the annular groove of the guide seat, the sliding half-pillar 22 and the fixed half-pillar 21 move downwards again as a whole, pressing down on the sealing ring so that the entire sealing ring enters the annular groove of the guide seat.
[0042] In some feasible embodiments, the anti-extrusion groove 32 is generally triangular in shape. When the sealing ring is stretched, the sealing ring is placed along the inclined side of the anti-extrusion groove 32. To reduce damage to the sealing ring, both the anti-extrusion groove 32 and the inner recess groove 33 have rounded chamfers on their side edges. The inner recess groove 33 is a rectangular groove with the same depth as the anti-extrusion groove 32 and the same height as the receiving arc groove 31.
[0043] As another specific embodiment of the automatic assembly equipment for embedded sealing rings of rear shock absorber guide seats provided in the application, it also includes a pickup table 41 and an assembly table 43. A placement groove is provided above the pickup table 41, and a sealing ring supply mechanism is connected to the side of the pickup table 41. A push ring rod 42 is slidably installed in the placement groove, and the push ring rod 42 is connected to a push ring drive 421. An assembly slide is provided on the assembly table 43. The first end of the assembly slide is connected to the guide seat supply mechanism, and the second end is a discharge port. A fixed ring push rod 44 is slidably installed on the side of the assembly table 43, and the fixed ring push rod 44 is connected to a push rod drive 441. After the transfer component 1 moves, the fixed half column 21 and the sliding half column 22 are located directly above the placement groove or the assembly slide.
[0044] Based on specific usage scenarios, a push ring drive 421 is provided to facilitate the effective stretching of the sliding half-pillar 22 when it is pushed into the receiving arc groove 31 and when it moves upward. A fixed ring push rod 44 is provided to fix the position of the guide seat when installing the sealing ring, which facilitates the insertion and removal of the sliding half-pillar 22 and the fixed half-pillar 21.
[0045] Furthermore, the fixed ring push rod 44 is provided with an arc-shaped groove that fits the side of the guide seat at one end near the guide seat, and a pressure plate 442 is fixedly installed above the arc-shaped groove, with a rectangular hole in the middle of the pressure plate 442.
[0046] It should be understood that by setting the arc groove and the pressure plate 442, the possibility of the guide seat being pulled up when the sliding half column 22 and the fixed half column 21 are pulled out is reduced.
[0047] Furthermore, a sliding groove is provided on the side of the assembly slide, and the fixed ring push rod 44 is slidably installed in the sliding groove. A sealing plate 443 is fixedly installed above the sliding groove.
[0048] It should be understood that by setting the sealing plate 443, the upward movement of the solid ring push rod 44 is restricted, thereby reducing the possibility that the solid ring push rod 44 and the push rod drive 441 will be subjected to radial force.
[0049] Furthermore, a force sensor is installed on the sealing plate 443.
[0050] It should be understood that by setting a force sensor, the force that the sliding half-pillar 22 and the fixed half-pillar 21 bring up the guide seat is sensed when they are pulled out. When the sealing ring is squeezed, the upward force that brings up the guide seat when the sliding half-pillar 22 and the fixed half-pillar 21 are pulled out increases. When the force sensor detects an abnormality, an alarm is triggered.
[0051] In some feasible configurations, both the pickup platform 41 and the assembly platform 43 are fixedly mounted on the equipment mounting frame. The pickup platform 41 is a rectangular plate with a rectangular placement groove. To facilitate the insertion of the sliding half-pillar 22 and the fixed half-pillar 21 into the sealing ring, another rectangular groove is provided at the bottom of the rectangular plate, creating a stepped surface within the placement groove. The push ring rod 42 is a rectangular plate with an arc shape at the end near the sealing ring to accommodate it. Both the push ring drive 421 and the push rod drive 441 are cylinders. A rectangular opening is provided on the side of the pickup platform 41 for engaging the sealing ring transport mechanism.
[0052] Assembly table 43 is a rectangular strip, and assembly slide is a rectangular groove. To facilitate the movement of the guide seat, a belt conveyor is installed inside the assembly slide, and the bottom of the assembly slide is attached to the upper side of the inner side of the belt. The sliding groove is a rectangular groove, the fixed ring push rod 44 is a rectangular plate, and the sealing plate 443 is a rectangular plate, which is bolted to the assembly table 43. The force sensor can be a strain gauge, which is fixedly installed on the upper side of the sealing plate 443, or a load cell, which is fixedly installed on the lower side of the sealing plate 443.
[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
