Description

Technical Field

[0001] The utility model relates to a C-type clamp spring introduction and assembly mechanism. Background Art

[0002] At present, the C-type circlip for shaft is a fastener installed on the shaft body and used to prevent the parts on the shaft body from moving axially. In order to improve the installation efficiency of the C-type circlip, many companies use automated equipment to install the C-type circlip. In the automated equipment, the cylinder drives the push rod to move and then the push rod pushes the C-type circlip to move so that the C-type circlip is clamped on the shaft. For example, the Chinese patent with publication number CN220863209U discloses an automatic circlip installation device, which can be used to install the C-type circlip on the shaft.

[0003] Among them, there is a slot on the C-type circlip. During the installation process, the slot on the C-type circlip needs to be aligned with the shaft to ensure that the C-type circlip can be smoothly mounted on the shaft. However, in the actual assembly process, it is found that when the C-type circlip is pushed and moved, the C-type circlip often deflects at an angle, causing the slot on the C-type circlip to deflect to one side and unable to align with the shaft, which in turn causes the C-type circlip to be unable to be installed on the shaft, resulting in installation failure and the need for staff to troubleshoot, which in turn affects the installation efficiency.

[0043] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0044] like Figures 1 to 8 As shown, a C-type circlip introduction assembly mechanism is used to assemble a C-type circlip 1 onto a shaft body 2, and includes a base 100, a top pressure plate 3, a top pressure cylinder 4 and a push mechanism;

[0045] The base 100 is provided with a mounting hole 5 for placing the shaft body 2;

[0046] The base 100 is also provided with a material receiving station 6 located behind the mounting hole 5 and used to receive the C-shaped retaining ring 1. The C-shaped retaining ring 1 has two card portions 7 and a card slot 8 located between the two card portions 7. The card slot 8 on the C-shaped retaining ring 1 in the material receiving station 6 is aligned with the shaft 2 in the mounting hole 5.

[0047] The pressing plate 3 is connected to the pressing cylinder 4, and two pressing parts 9 are provided on the pressing plate 3, and the pressing parts 9 correspond to the card parts 7 on the C-shaped clamping spring 1 one by one;

[0048] The pressing cylinder 4 is connected to the base 100, and is used to drive the pressing plate 3 to move backward so that the two pressing parts 9 on the pressing plate 3 respectively press against the corresponding card parts 7 on the C-shaped clamping spring 1 in the material receiving station 6;

[0049] The pushing mechanism is used to abut against the rear end of the C-shaped retaining ring 1 in the material receiving station 6 and push the C-shaped retaining ring 1 and the top pressure plate 3 to move forward together so that the C-shaped retaining ring 1 moves forward to the shaft body 2 stuck in the mounting hole 5. Specifically, the shaft body 2 is first inserted into the mounting hole 5, and the C-shaped retaining ring 1 is conveyed to the material receiving station 6, and then the top pressure cylinder 4 drives the top pressure plate 3 to move backward so that the two top pressure parts 9 on the top pressure plate 3 respectively abut against the corresponding card parts 7 on the C-shaped retaining ring 1 in the material receiving station 6, and then the pushing mechanism abuts against the rear end of the C-shaped retaining ring 1 in the material receiving station 6 and pushes the C-shaped retaining ring 1 and the top pressure plate 3 to move forward together so that the C-shaped retaining ring 1 moves forward to the shaft body 2 stuck in the mounting hole 5, thereby completing the installation of the C-shaped retaining ring 1 on the shaft body 2. Among them, in the process that the pushing mechanism pushes the C-shaped retaining spring 1 to move forward, the two pressing parts 9 on the pressing plate 3 always press the two card parts 7 on the C-shaped retaining spring 1, thereby preventing the C-shaped retaining spring 1 from angular deflection during the movement, thereby ensuring that the card slot 8 on the C-shaped retaining spring 1 is always aligned with the shaft body 2 in the mounting hole 5, so that the C-shaped retaining spring 1 can be successfully installed on the shaft body 2, which not only improves the success rate of the installation of the C-shaped retaining spring 1, but also improves the efficiency of the installation.

[0050] To be more specific, in the process of the C-shaped retaining ring 1 and the pressing plate 3 moving forward together, the pressing cylinder 4 is pushed to gradually retract, and the pressing cylinder 4 is used to apply a backward force to the pressing plate 3 so that the pressing part 9 on the pressing plate 3 is always pressed against the card part 7 on the C-shaped retaining ring 1.

[0051] like Figure 4 , 5 As shown in Figures 6 and 8, the pressing plate 3 is further provided with an open groove 10 located between the two pressing parts 9, and the opening direction of the open groove 10 is toward the rear. When the pressing cylinder 4 drives the pressing plate 3 to move backward so that the pressing part 9 abuts against the corresponding card part 7 on the C-shaped retaining ring 1 in the material receiving station 6, the shaft body 2 is snapped into the open groove 10.

[0052] like Figure 1 , 2 As shown in , 3 and 6, the pushing mechanism may include a pushing component and a pushing cylinder 11;

[0053] The material pushing component is located behind the material receiving station 6 and is slidably connected to the base 100 along the front-rear direction;

[0054] The pushing cylinder 11 is connected to the pushing component and is used to drive the pushing component to move forward so that the pushing component abuts against the rear end of the C-shaped retaining ring 1 in the receiving station 6 and pushes the C-shaped retaining ring 1 in the receiving station 6 forward to the shaft 2 stuck in the mounting hole 5.

[0055] like Figures 1 to 8 As shown, the pusher component may include a connecting seat 12 and a push rod 13;

[0056] The connecting seat 12 and the push rod 13 are both slidably connected to the base 100 along the front-back direction;

[0057] The front end of the push rod 13 is used to abut against the C-shaped retaining spring 1 in the material receiving station 6;

[0058] The rear end of the push rod 13 is connected to the connecting seat 12;

[0059] The push cylinder 11 is connected to the base 100 and the connecting seat 12 and is used to drive the connecting seat 12 to move forward, thereby driving the push rod 13 to move forward so that the push rod 13 abuts against the rear end of the C-shaped retaining ring 1 in the material receiving station 6 and pushes the C-shaped retaining ring 1 in the material receiving station 6 to move forward to the shaft body 2 stuck in the mounting hole 5. Specifically, in the process of the push rod 13 pushing the C-shaped retaining ring 1 forward, the C-shaped retaining ring 1 drives the top pressure plate 3 to move forward together, thereby making the top pressure part 9 on the top pressure plate 3 always press against the card part 7 on the C-shaped retaining ring 1, thereby preventing the C-shaped retaining ring 1 from angular deflection, and ensuring that the card slot 8 on the C-shaped retaining ring 1 is always aligned with the shaft body 2 in the mounting hole 5, thereby enabling the C-shaped retaining ring 1 to be successfully installed on the shaft body 2. To be more specific, the thrust of the pushing cylinder 11 is greater than the thrust of the pressing cylinder 4. Therefore, when the pushing cylinder 11 is extended, it can drive the connecting seat 12, the push rod 13, the C-shaped retaining ring 1 and the pressing plate 3 to move forward together. At the same time, since the thrust of the pressing cylinder 4 is smaller, the pressing cylinder 4 will be driven to retract. The pressing cylinder 4 can apply a backward force to the pressing plate 3 so that the pressing part 9 on the pressing plate 3 is always pressed against the card part 7 on the C-shaped retaining ring 1.

[0060] like Figure 1 , 2As shown in , 3 and 6, the connecting seat 12 is provided with an abutting portion 14, and the base 100 is connected with a bumper 15 for abutting against the abutting portion 14 when the connecting seat 12 moves forward into position; specifically, the bumper 15 is used to play a buffering role; in this embodiment, the base 100 is provided with a limit blocking portion 16, and the connecting seat 12 is connected with a limit bolt 17, and when the pushing cylinder 11 drives the connecting seat 12 to move backward into position, the limit bolt 17 abuts against the limit blocking portion 16.

[0061] like Figure 7 As shown, the shaft body 2 may be provided with an annular groove 18 for assembling the C-shaped retaining ring 1;

[0062] The base 100 is provided with a first photoelectric sensor 19 for detecting whether the shaft body 2 in the mounting hole 5 is installed upside down. The first photoelectric sensor 19 is aligned with the annular groove 18 on the shaft body 2 installed in the mounting hole 5 and is used to emit light through the outer periphery of the annular groove 18. Specifically, if the shaft body 2 is not installed upside down, after the shaft body 2 is installed in the mounting hole 5, the annular groove 18 on the shaft body 2 is aligned with the first photoelectric sensor 19, and the light emitted by the first photoelectric sensor 19 passes through the outer periphery of the annular groove 18. If the shaft body 2 is installed upside down in the mounting hole 5, the height of the annular groove 18 cannot be aligned with the first photoelectric sensor 19, so the light emitted by the first photoelectric sensor 19 cannot pass through the annular groove 18, but will be blocked by the inverted shaft body 2, thereby being able to detect that the shaft body 2 is installed upside down.

[0063] like Figure 3 , 4 As shown in , 5 and 7, the base 100 may be provided with a feed channel 20 and an introduction channel 21;

[0064] The mounting hole 5 is provided in the introduction channel 21;

[0065] One end of the feed channel 20 is connected to one end of the introduction channel 21;

[0066] The material receiving station 6 is arranged at the connecting point of the feed channel 20 and the introduction channel 21; specifically, the feed channel 20 is used to be connected to a vibration plate, and the vibration plate transports the C-shaped retaining ring 1 to the feed channel 20, and then the C-shaped retaining ring 1 is transported from the feed channel 20 to the material receiving station 6.

[0067] like Figures 1 to 7 As shown, the C-type clamp spring introduction assembly mechanism may further include an anti-rotation mechanism, and the anti-rotation mechanism may include, for example but not limited to, the following structure, which includes a connecting bracket 22, a telescopic cylinder 23, and a guide rod 24;

[0068] The base 100 is provided with a slide groove 25 communicating with the introduction channel 21, and the guide rod 24 is slidably disposed in the slide groove 25;

[0069] The connecting bracket 22 is connected to the base 100;

[0070] The telescopic cylinder 23 is connected to the connecting bracket 22, and the telescopic cylinder 23 is also connected to the guide rod 24 and is used to drive the guide rod 24 to move into the introduction channel 21 or exit the introduction channel 21;

[0071] When the C-shaped retaining spring 1 moves from the feed channel 20 to the receiving station 6, the card portion 7 on the C-shaped retaining spring 1 abuts against the guide rod 24 extending into the introduction channel 21 to prevent the C-shaped retaining spring 1 from angular deflection. Figure 3 As shown, first, the telescopic cylinder 23 drives the guide rod 24 to extend into the introduction channel 21, and the C-shaped clip 1 is conveyed to the feed channel 20 and then to the receiving station 6 under the conveyance of the vibration plate. When the C-shaped clip 1 moves to the receiving station 6, the card portion 7 on the C-shaped clip 1 abuts against the guide rod 24 extending into the introduction channel 21 to prevent the C-shaped clip 1 from angular deflection. Then, as shown in FIG. Figure 4 As shown, the telescopic cylinder 23 drives the guide rod 24 to withdraw from the introduction channel 21, and the pressing cylinder 4 drives the pressing plate 3 to move backward so that the pressing portion 9 on the pressing plate 3 abuts against the card portion 7 on the C-shaped clamping spring 1. Figure 5 As shown, the pushing cylinder 11 drives the connecting seat 12 and the push rod 13 to move forward, and the push rod 13 pushes the C-shaped retaining ring 1 in the receiving station 6 forward into the introduction channel 21, thereby moving the C-shaped retaining ring 1 to the shaft body 2 stuck in the mounting hole 5.

[0072] like Figure 7 As shown, the base 100 may include a seat body 26 and a bracket 27, the mounting hole 5 is provided on the seat body 26, the bracket 27 is connected to the seat body 26 and is located below the mounting hole 5, and the lower end of the shaft body 2 passes through the mounting hole 5 and abuts against the bracket 27 so as to support the shaft body 2 in the mounting hole 5 through the bracket 27.

[0073] like Figure 7As shown, the bracket 27 is connected with a second photoelectric sensor 28 for detecting whether the lower end of the shaft body 2 abuts against the bracket 27; specifically, if the second photoelectric sensor 28 can detect the shaft body 2, it means that the lower end of the shaft body 2 abuts against the bracket 27 after passing through the mounting hole 5, and further indicates that the shaft body 2 is inserted into the mounting hole 5; if the second photoelectric sensor 28 does not detect the shaft body 2, it means that the shaft body 2 is not inserted into the mounting hole 5 or the shaft body 2 is not inserted into the mounting hole 5. In this embodiment, when the second photoelectric sensor 28 detects the shaft body 2 and the first photoelectric sensor 19 does not detect the shaft body 2, it means that the shaft body 2 is installed in place. Wherein, both the first photoelectric sensor 19 and the second photoelectric sensor 28 can be through-beam photoelectric sensors.

[0074] In this embodiment, the base 100 further includes a mounting frame 29 and a support frame 30, wherein the support frame 30 is connected to the mounting frame 29, and the top pressure cylinder 4 is connected to the support frame 30. The seat body 26 is connected to the mounting frame 29, the feed channel 20, the introduction channel 21 and the slide 25 are all arranged on the seat body 26, the material receiving station 6 is arranged on the seat body 26, the position limiting blocking portion 16 is arranged on the seat body 26, the connecting seat 12 and the push rod 13 are both slidably connected to the seat body 26 along the front-rear direction, the first photoelectric sensor 19 is installed in the seat body 26, and the push cylinder 11, the bumper 15 and the connecting bracket 22 are all connected to the seat body 26.

[0075] To summarize, first, the shaft body 2 is inserted into the mounting hole 5, the C-shaped retaining ring 1 is conveyed to the material receiving station 6, and then the pressing cylinder 4 drives the pressing plate 3 to move backward so that the two pressing parts 9 on the pressing plate 3 respectively press against the corresponding card parts 7 on the C-shaped retaining ring 1 in the material receiving station 6, and then the pushing mechanism presses against the rear end of the C-shaped retaining ring 1 in the material receiving station 6 and pushes the C-shaped retaining ring 1 and the pressing plate 3 to move forward together so that the C-shaped retaining ring 1 moves forward to the shaft body 2 stuck in the mounting hole 5, thereby completing the installation of the C-shaped retaining ring 1 on the shaft body 2. In the process of the pushing mechanism pushing the C-shaped retaining spring 1 forward, the two pressing parts 9 on the pressing plate 3 always press against the two card parts 7 on the C-shaped retaining spring 1, thereby preventing the C-shaped retaining spring 1 from angularly deflecting during the movement, thereby ensuring that the card slot 8 on the C-shaped retaining spring 1 is always aligned with the shaft body 2 in the mounting hole 5, so that the C-shaped retaining spring 1 can be successfully installed on the shaft body 2, which not only improves the success rate of the installation of the C-shaped retaining spring 1, but also improves the efficiency of the installation. In addition, in the process of the C-shaped retaining spring 1 and the pressing plate 3 moving forward together, the pressing cylinder 4 is pushed to gradually retract, and the pressing cylinder 4 is used to apply a backward force to the pressing plate 3 so that the pressing part 9 on the pressing plate 3 always presses against the card parts 7 on the C-shaped retaining spring 1.
