Description

Technical Field

[0001] This utility model belongs to the field of automotive parts assembly technology, specifically relating to an automatic O-ring installation mechanism. Background Technology

[0002] In the manufacturing and installation process of automotive engines, O-rings play a significant role in friction and sealing on shaft-type parts and are widely used. In other fields, they also play a crucial role in the end-face sealing of cylinder piston rods. Due to the special nature of their material, O-rings require their outer diameter to be increased before installation during normal assembly. The material properties of O-rings make manual operation difficult and inconsistent in quantity; careless handling can lead to breakage. Only one workpiece can be processed at a time, resulting in low processing efficiency. Furthermore, misalignment between the workpiece and the O-ring can affect the installation process, generally requiring manual support and fixation of the workpiece, which is time-consuming and labor-intensive.

[0003] Based on the aforementioned technical issues, an automatic O-ring installation mechanism is proposed. Utility Model Content

[0004] In view of the problems raised in the background art above, the purpose of this utility model is to provide an automatic O-ring installation mechanism.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic O-ring installation mechanism includes a frame connected to a mounting back plate. The mounting back plate is equipped with an automatic bidirectional moving mechanism. Two output ends of the automatic bidirectional moving mechanism are respectively connected to O-ring installation components with identical structures and symmetrical arrangement. Vibrating feeders are provided on both sides of the frame, and the vibrating feeders are provided with material transfer channels. A rectangular placement plate is detachably connected to the frame. The rectangular placement plate is located directly below the O-ring installation components, and a workpiece limiting mechanism is connected to the rectangular placement plate.

[0007] Further specifying, the automatic bidirectional moving mechanism includes a first motor connected to one side of the mounting back plate, the output end of the first motor connected to a first double-ended lead screw, the two ends of the outer wall of the first double-ended lead screw shaft connected to matching first nut sleeves, the first nut sleeves connected to a first slider, the mounting back plate having a first sliding groove adapted to the sliding of the first slider, the first slider connected to a vertical mounting plate, and a single O-ring mounting assembly connected to one side of the vertical mounting plate. This structural design, with the first motor as the power end, drives the O-ring mounting assemblies on both sides to automatically move towards and away from each other, facilitating the effect of laterally changing the position of the O-ring mounting assemblies on both sides.

[0008] Furthermore, the O-ring mounting assembly includes a vertical mounting plate side, a Z-axis mounting module servo motor, a Z-axis mounting module, and an O-ring mounting cylinder connected from top to bottom. This structural design facilitates the automatic rotation of the O-ring mounting cylinder to clamp and install the O-ring.

[0009] Further defining the workpiece limiting mechanism, it includes side pillars connected to both sides of a rectangular placement plate. Each side pillar has a dovetail-shaped groove. A second double-ended lead screw and a guide rod are respectively connected to the dovetail-shaped grooves on both sides. A second motor is connected to the end of the second double-ended lead screw. Matching second nut sleeves are connected to both ends of the outer wall of the second double-ended lead screw shaft. Dovetail-shaped sliders are connected to both ends of the guide rod and the second nut sleeve. A U-shaped mounting bracket is connected between the two dovetail-shaped sliders on corresponding sides. The U-shaped mounting bracket is connected to two U-shaped mounting clips via second bolts. Each U-shaped mounting clip has multiple limiting holes. An arc-shaped limiting plate is connected to the end of each U-shaped mounting clip. Two opposing arc-shaped limiting plates are located directly below a single O-ring mounting assembly. A rubber pad is embedded between the two opposing arc-shaped limiting plates on the rectangular placement plate. This structural design facilitates simultaneous limiting and fixing of two workpieces, and fixes the workpieces directly below the two O-ring mounting assemblies, facilitating subsequent precise processing.

[0010] Furthermore, the rectangular placement plate is connected to inclined brackets at both ends, and the inclined brackets are connected to mounting rings. The mounting rings are sleeved on the outer wall of the frame shaft, and multiple bolts connect the mounting rings and the frame. This structural design facilitates the installation and disassembly of the rectangular placement plate and its connecting components.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model includes an automatic bidirectional moving mechanism, two O-ring mounting assemblies, two vibrating feeders, a rectangular placement plate, and a workpiece limiting mechanism, among other connecting components. It can simultaneously limit and fix two workpieces, then automatically change the lateral position of the two O-ring mounting assemblies to open and clamp the O-rings. This allows for simultaneous automatic installation of two workpieces and O-rings, improving processing efficiency. The automatic opening and clamping of the O-rings solves the problem of O-ring damage caused by unstable force application due to operator difficulty. Simultaneously, the workpiece limiting mechanism on the rectangular placement plate limits and fixes both workpieces simultaneously, enhancing workpiece stability during processing and preventing workpiece slippage from affecting the installation progress. The high degree of automation further improves processing efficiency. Attached Figure Description

[0025] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1, as Figure 1 , Figure 2 and Figure 3 As shown, the mounting back plate 2 is equipped with an automatic bidirectional moving mechanism. The two output ends of the automatic bidirectional moving mechanism are respectively connected to O-ring mounting components with the same structure and symmetrical arrangement. Vibrating feeders 3 are provided on both sides of the frame 1. The vibrating feeders 3 are provided with material transfer channels 301. The frame 1 is detachably connected to a rectangular placement plate 4. The rectangular placement plate 4 is located directly below the O-ring mounting components. The rectangular placement plate 4 is connected to a workpiece limiting mechanism.

[0027] In this embodiment, the working process of the device is as follows:

[0028] First, the workpieces to be fitted with O-rings are fixed on the upper side of the rectangular placement plate 4 by the workpiece limiting mechanism. Then, the vibrating feeder 3 is controlled to feed the O-rings to the material transfer channel 301. The material transfer channel 301 transfers the O-rings to the end position. At this time, the central controller drives the automatic bidirectional moving mechanism to move the respective O-ring mounting components to the upper part of the end position of the material transfer channel 301. Then, the O-ring mounting components are controlled to open the O-rings for automatic clamping. After that, the automatic bidirectional moving mechanism is controlled to move the respective O-ring mounting components and O-rings to the upper part of the two workpieces. The O-ring mounting components sink to the processing position and put the O-rings on the workpieces or extend into the workpieces. Finally, the O-ring mounting components are reset and rise to the original position to clamp the next O-ring.

[0029] In summary, this structural design allows for the simultaneous automatic installation of two workpieces and O-rings, improving processing efficiency. It requires fewer manual intervention steps, automatically opening and clamping the O-rings to prevent damage caused by unstable force application during manual operation. Furthermore, a workpiece limiting mechanism on the rectangular placement plate 4 simultaneously limits and fixes both workpieces, enhancing their stability during processing and preventing workpiece slippage from affecting the installation progress. This high degree of automation further enhances processing efficiency.

[0030] Example 2, as Figure 1 and Figure 3 As shown, this embodiment adds the following structure based on embodiment 1: the automatic bidirectional moving mechanism includes a first motor 201 connected to one side of the mounting back plate 2, the output end of the first motor 201 is connected to a first double-ended lead screw 202, the two ends of the outer wall of the first double-ended lead screw 202 are connected to matching first nut sleeves 203, the first nut sleeves 203 are connected to a first slider 204, the mounting back plate 2 is provided with a first slide groove 2001 adapted to the sliding of the first slider 204, the first slider 204 is connected to a vertical mounting plate 205, and a single O-ring mounting assembly is connected to one side of the vertical mounting plate 205.

[0031] In this embodiment, when the material conveying channel 301 transmits the O-ring to the end position, the central controller starts the first motor 201. The first motor 201 drives the first double-ended lead screw 202 at the output end. When the first double-ended lead screw 202 rotates, it drives the first nut sleeve 203 and the first slider 204 at both ends to move in opposite directions in the first slide groove 2001. When the two first sliders 204 move, they respectively drive the vertical mounting plate 205 and the O-ring mounting assembly connected to them to move in opposite directions, so as to automatically drive the O-ring mounting assembly to change its position along the Y-axis.

[0032] Example 3, as Figure 1As shown, this embodiment adds the following structure to the embodiment 1: the O-ring mounting assembly includes a vertical mounting plate 205, a Z-axis mounting module servo motor 5, a Z-axis mounting module 501 and an O-ring mounting cylinder 502 connected from top to bottom.

[0033] In this embodiment, after the material transfer channel 301 transmits the O-ring to the end position, the O-ring mounting assembly moves to directly above the O-ring. At this time, the Z-axis mounting module servo motor 5 and the Z-axis mounting module 501 cooperate to lower the O-ring mounting cylinder 502 to the upper position of the O-ring. The O-ring mounting cylinder 502 then extends into the O-ring and opens, placing the O-ring on the gripper. Then, the O-ring mounting assembly moves to the upper side of the workpiece. Simultaneously, the Z-axis mounting module 501 rises and then falls, and the O-ring mounting cylinder 502 pushes open, placing the O-ring on the workpiece. Finally, the Z-axis mounting module servo motor 5, the Z-axis mounting module 501, and the O-ring mounting cylinder 502 reset to await the next workpiece processing.

[0034] Example 4, as Figure 1 and Figure 2 As shown, this embodiment adds the following structure based on embodiment 1: the workpiece limiting mechanism includes side posts 6 connected to both sides of the rectangular placement plate 4. The side posts 6 are provided with dovetail-shaped slide grooves 601. The dovetail-shaped slide grooves 601 on both sides are respectively connected to a second double-ended lead screw 602 and a guide round rod 603. The end of the second double-ended lead screw 602 is connected to a second motor 604. The two ends of the outer wall of the shaft of the second double-ended lead screw 602 are connected to matching second nut sleeves 605. The two ends of the guide round rod 603 and the second nut sleeve 605 are both connected to dovetail-shaped slide grooves 602. A tail-shaped slider 606 is connected to a U-shaped mounting bracket 607 between two dovetail-shaped sliders 606 on the corresponding side. The U-shaped mounting bracket 607 is connected to two U-shaped mounting clips 7 by a second bolt 608. The U-shaped mounting clips 7 are provided with multiple limiting round holes 7001. An arc-shaped limiting plate 701 is connected to the end of the U-shaped mounting clip 7. The two opposing arc-shaped limiting plates 701 are located directly below a single O-ring mounting assembly. A rectangular placement plate 4 has a rubber pad 4001 embedded between the two opposing arc-shaped limiting plates 701.

[0035] In this embodiment, after the two workpieces are placed on the two rubber pads 4001 of the rectangular placement plate 4, the central controller turns on the second motor 604. The second motor 604 drives the second double-ended lead screw 602 at the output end to rotate. When the second double-ended lead screw 602 rotates, it drives the second nut sleeve 605 and the dovetail slider 606 to move in the dovetail groove 601. When the dovetail slider 606 drives the U-shaped mounting bracket 607 to move, the dovetail slider 606 at the other end of the U-shaped mounting bracket 607 moves along the guide rod 603 in the dovetail groove 601. The U-shaped mounting brackets 607 on both sides move towards each other to limit and fix the workpiece between the corresponding two arc-shaped limiting plates 701, so that the workpiece is located directly below the O-ring mounting cylinder 502, preventing the workpiece from shifting and affecting the installation process.

[0036] Example 5, as Figure 1 and Figure 2 As shown, this embodiment adds the following structure based on embodiment 1: the rectangular placement plate 4 is connected to both ends of an inclined bracket 401, the inclined bracket 401 is connected to an installation ring 402, the installation ring 402 is sleeved on the outer wall of the frame 1 shaft, and multiple bolts are connected between the installation ring 402 and the frame 1.

[0037] In this embodiment, two mounting rings 402 are respectively fitted onto both ends of the frame 1 and then fixed with multiple bolts, which facilitates the installation, disassembly, and subsequent maintenance of the rectangular placement plate 4 and its connecting components.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
