[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0033] Example 1
[0034] Please see Figure 1-4 This utility model provides a technical solution: an automatic snap ring pressing device, comprising:
[0035] Support frame 1;
[0036] The support module 2 includes a linear guide rail 21 and a support base 22. The linear guide rail 21 is fixedly mounted on the support frame 1, and the support base 22 is fixedly mounted on the slider of the linear guide rail 21. The product 9 is placed on the support base 22.
[0037] The circlip supply module 3 includes an intermediate seat 31, a fixed seat 32, a guide 33, and a guide seat 34. The intermediate seat 31 is fixedly installed on the support frame 1. The fixed seats 32 are symmetrically arranged on both sides of the intermediate seat 31. The guide 33 is fixedly installed on the fixed seat 32. The top of the guide 33 extends into the feed port 341 of the guide seat 34.
[0038] The pressing module 4 includes a driving component 41, a linkage seat 42, and a retaining ring clamp 43. The linkage seat 42 is fixedly installed at the output end of the driving component 41. Retaining ring clamps 43 are symmetrically arranged on both sides of the linkage seat 42. Retaining ring clamps 43 are provided on the retaining ring clamps 43 with retaining ring grooves 431 corresponding to the bottom end of the guide component 33.
[0039] When the automatic snap ring pressing device is working, the user only needs to place the product 9 to be pressed into the support seat 22 of the support module 2. Then, the support seat 22 moves to the middle seat 31 of the snap ring supply module 3, and two snap rings are pressed in simultaneously by the pressing module 4. After the snap ring pressing is completed, the module removes and resets the module to prepare for the next snap ring pressing of the product 9, effectively improving the pressing quality and efficiency of snap rings. The snap rings are neatly arranged by the guide 33 in the snap ring supply module 3 and fed into the snap ring groove 431 of the snap ring clamp 43, accurately delivering the snap rings to the required pressing position and stably supplying snap rings.
[0040] The support base 22 has symmetrically arranged support blocks 221 on both sides. The support blocks 221 are provided with positioning grooves, and the end of the product 9 is engaged in the positioning groove. The end of the drive shaft in the product 9 is engaged in the positioning groove at the top of the support block 221 to achieve horizontal positioning of the product 9, so as to facilitate the subsequent engagement of the retaining ring.
[0041] The driving component 41 can be a push-pull clamp or a driving cylinder. As shown in the figure, the driving component 41 can quickly realize the reciprocating motion of the linkage seat 42 through the push-pull clamp. In order to further improve the assembly efficiency of the snap ring and the degree of automation, the driving cylinder can realize the reciprocating motion of the linkage seat 42.
[0042] Working principle: When assembling product 9, the toner cartridge and drive shaft assembly of product 9 are first placed on the support 22. Then, the support 22 slides along the linear guide 21 to below the middle seat 31 of the retaining ring supply module 3, waiting for the retaining ring to be pressed in.
[0043] The retaining ring is fed into the feed port 341 of the guide seat 34 in the retaining ring supply module 3, and slides along the guide 33 toward the middle seat 31. The retaining ring at the end of the guide 33 changes from a horizontal state to a vertical state and enters the retaining ring clamp 43 of the pressing module 4.
[0044] Then, the drive unit 41 drives the linkage seat 42 and the retaining ring clamp 43 to move downward. The retaining ring clamp 43 is supported and positioned by the intermediate seat body 31. The retaining ring in the retaining ring groove 431 of the retaining ring clamp 43 is pressed into the drive shaft of the product 9 through the bottom opening. The bottom of the retaining ring clamp 43 is composed of two separable sheets. The grooves on the two separable sheets are joined together to form the retaining ring groove 431.
[0045] Example 2
[0046] Based on the above embodiments, this embodiment further improves upon the following technical solution: a positioning element 5 is provided below the intermediate seat 31, and symmetrically arranged support plates 51 are provided on both sides of the positioning element 5, with an opening 511 at the end of the support plate 51.
[0047] As the support seat 22 moves to the middle seat 31 of the retaining ring supply module 3, the drive shaft in the product 9 engages with the opening 511 of the support plate 51. The support plates 5 on both sides of the positioning member 5 further position and support the product 9, improving the quality of the retaining ring pressing in.
[0048] In addition, the end of the support plate 51 is provided with a bent edge 512 to avoid collision damage with the toner canister on the product 9.
[0049] Example 3
[0050] This embodiment further improves upon the above embodiment by providing the following technical solution: a limit stop 211 is provided at one end of the linear guide 21, and a buffer block 222 corresponding to the limit stop 211 is provided on the support 22. The buffer block 222 is threadedly connected to the support 22 via a screw, making it detachable.
[0051] The buffer block 222 can be made of rubber to absorb the inertial impact during the reciprocating motion of the support 22, while limiting the stroke of the support 22, effectively ensuring the accurate pressing position of the retaining ring.
[0052] On the other hand, the support frame 1 is provided with an adjusting bolt 11 whose position corresponds to the support seat 22. Similar to the detachable buffer block 222, the adjusting bolt 11 is on the other side of the support seat 22. By rotating it, the length of the bolt extending out of the support frame 1 is adjusted, which limits the stroke of the support seat 22 and effectively ensures that the snap ring is pressed into the correct position.
[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
