Description

Technical Field

[0001] This invention relates to a multi-ring sharing anti-misplacement device for assembly lines, belonging to the field of tooling technology. Background Technology

[0002] Because different products are assembled on the assembly line, different retaining rings are required. To accommodate retaining rings of varying thicknesses with different clearances, the assembly line is equipped with a retaining ring selection error-proofing device. During use, retaining rings are placed sequentially on different retaining ring guides in descending order of thickness. The device automatically prompts the user to select the appropriate thickness retaining ring from the guides based on the measured clearance. However, the existing retaining ring selection error-proofing device only works for retaining rings of the same shape but different thicknesses. With the expansion of the production line, multiple products and series are being produced on the same line, and retaining rings of different shapes all require corresponding retaining ring error-proofing devices to prevent errors. Figure 3 The second snap ring of the conventional shape shown is usually placed on the cylindrical snap ring guide post, while Figure 2 The first snap ring shown has a large opening, which makes it easy for it to slip off the cylindrical snap ring guide post due to rotation. In actual use, snap ring guide posts of various shapes need to be configured according to the shape of the snap ring, which brings inconvenience to actual production and increases costs. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a multi-circlip common anti-misplacement device for assembly lines, which solves the problem that the circlip guide post in the prior art cannot be adapted to circlips of different shapes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multi-circlip shared anti-misplacement device for assembly lines includes a button fixing seat, a left stop bar, a circlip guide post, a right stop bar, a nylon pad, and a damping circlip seat;

[0006] The retaining spring guide post is hollow, and the button fixing seat and nylon pad are respectively inserted into the hollow interiors at both ends of the retaining spring guide post. The lower end face of the nylon pad is flush with the end face of the retaining spring guide post.

[0007] The left and right stop bars are sequentially fitted onto the outer circle of the snap ring guide post. The left stop bar includes an upper left stop ring, a lower left stop ring, and a left stop plate. The upper left stop ring and the lower left stop ring are fixed to both ends of the left stop plate. The right stop bar includes an upper right stop ring, a lower right stop ring, and a right stop plate. The upper right stop ring and the lower right stop ring are fixed to both ends of the right stop plate. The two ends of the upper left stop ring are respectively attached to the step ring of the button fixing seat and the upper right stop ring. The other end of the upper right stop ring is attached to the end face of the snap ring guide post. The two ends of the lower left stop ring are respectively attached to the end face of the snap ring guide post and the lower right stop ring. The other end of the lower right stop ring is attached to the damping retainer.

[0008] Furthermore, the aforementioned left and right baffles are L-shaped, with one side being arc-shaped and fitting against the outer circle of the snap ring guide post, and the other side being straight to abut against the snap ring.

[0009] Furthermore, the aforementioned damping seat includes a column and a chassis, the column being adapted to the inner ring of the nylon pad, and the chassis fitting against the lower right retaining ring.

[0010] Furthermore, the aforementioned also includes a fixing bolt, the end of which is inserted into the hollow interior of the snap ring guide post, and the lower end face of the fixing bolt is in contact with the nylon pad.

[0011] Furthermore, the aforementioned button holder is hollow, and a button is installed inside.

[0012] Furthermore, the aforementioned also includes a nut, which cooperates with a fixing bolt to fix the snap ring guide post to the mounting plate.

[0013] The beneficial effects achieved by this invention are as follows:

[0014] By adding a paddle to the snap ring guide post, the placement of snap rings of different shapes can be solved. This method is versatile, and multiple specifications of snap rings can be used with one snap ring guide post. The same snap ring guide post facilitates the design and installation of the installation method and also helps to reduce the production cost caused by using multiple snap ring guide posts.

Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0027] This embodiment discloses a multi-ring sharing anti-misplacement device for assembly lines, such as... Figure 1 As shown, the device includes a button 1, a button mounting base 2, a left stop bar 3, a snap ring guide post 4, a right stop bar 5, a nylon pad 6, a damping clip base 7, a fixing bolt 8, and a nut 9, providing a solution for using a snap ring anti-misoperation device for different types of snap rings.

[0028] The retaining ring guide post 4 is hollow, and the outer circular surface of the button fixing seat 2 is inserted into the hollow interior of the retaining ring guide post 4. The head of the button fixing seat 2 has a stepped ring, the outer diameter of which is larger than the outer diameter of the retaining ring guide post 4. This facilitates the removal of the button fixing seat 2 and also allows for subsequent axial fixing of the left and right retaining strips 3 and 5. The end of the fixing bolt 8 is inserted into the hollow interior of the other end of the retaining ring guide post 4. A circular nylon pad 6 is also fitted inside the hollow interior of the retaining ring guide post 4, with one end fitting against the end of the fixing bolt 8 and the other end flush with the end face of the retaining ring guide post 4. Figure 10 As shown, the damping seat 7 includes a column 71 and a base 72, with the column 71 being adapted to the inner ring of the nylon pad 6.

[0029] The left retaining strip 3 and the right retaining strip 5 are inserted into one end of the fixing bolt 8 mounted on the snap ring guide post 4. The left retaining strip 3 includes an upper left retaining ring 31, a lower left retaining ring 33, and a left retaining plate 32. The right retaining strip 5 includes an upper right retaining ring 51, a lower right retaining ring 53, and a right retaining plate 52. The upper left retaining ring 31, the lower left retaining ring 33, the upper right retaining ring 51, and the lower right retaining ring 53 are circular rings with inner diameters that match the outer diameter of the snap ring guide post 4. The upper left retaining ring 31 and the lower left retaining ring 33 are fixed to both ends of the left retaining plate 32, and the upper right retaining ring 51 and the lower right retaining ring 53 are fixed to both ends of the right retaining plate 52. The left retaining plate 32 and the right retaining plate 52 are L-shaped, with one side being arc-shaped to fit against the outer circle of the snap ring guide post 4, and the other side being straight to abut against the snap ring. The two ends of the upper left retaining ring 31 are respectively attached to the stepped ring of the button fixing seat 2 and the upper right retaining ring 51, and the other end of the upper right retaining ring 51 is attached to the end face of the snap ring guide post 4; the two ends of the lower left retaining ring 33 are respectively attached to the end face of the snap ring guide post 4 and the lower right retaining ring 53, and the other end of the lower right retaining ring 53 is attached to the chassis 72 of the damping seat 7.

[0030] The button mounting base 2 is also hollow, and button 1 is installed inside. Button 1 is wired and remotely connected to I / O. When button 1 is pressed, a trigger signal is sent to the device PLC. The PLC program will perform corresponding selection and storage work according to the trigger signal.

[0031] During installation, first insert the fixing bolt 8 and the button fixing seat 2 into the two ends of the retaining spring guide post 4 respectively. Then, put the nylon pad 6 on the thread of the fixing bolt 8 and push it all the way in so that it completely fits the end plane of the fixing bolt 8. Next, put the left baffle 3 and the right baffle 5 into the retaining spring guide post 4. Finally, put on the damping retaining seat 7 so that it fits tightly against the end face of the lower right retaining ring 53. Figure 7 As shown, a mounting plate is provided on the workbench. The mounting plate has holes in which the fixing bolts 8 are inserted. Nuts 9 are used to tighten the mounting plate on the back to fix the snap ring guide post 4 to the mounting plate.

[0032] When the first snap ring is used in production, such as Figure 4 As shown, the left stop bar 3 and right stop bar 5 on the snap ring guide post 4 are pried open to block both ends of the first snap ring, preventing the first snap ring from slipping off the snap ring guide post 4 due to the center of gravity rotating.

[0033] When a second retaining ring is used in production, such as Figure 5 As shown, close the two baffles on the snap ring guide post 4 with the baffles facing down so that the snap ring can be easily removed from the snap ring guide post.

[0034] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
