Description

Technical Field

[0001] The utility model belongs to the field of clamp spring press-fitting, in particular to a clamp spring press-fitting device. Background Art

[0002] Turbocharging is usually achieved by using a turbocharger, and the intermediate housing is the core component of the turbocharger. Figure 1 As shown, a through hole is opened at the center axis position of the intermediate shell, a boss is formed in and above the through hole, a retaining spring groove is opened below the boss, and a retaining spring needs to be assembled in the retaining spring groove.

[0003] In practice, to assemble the circlip into the circlip groove in the intermediate housing, the circlip is usually first placed into the through-hole as required, and then the press fitter is inserted into the through-hole. The press fitter pushes the circlip until it snaps into the circlip groove. Although this method can complete the circlip assembly, if the press fitter tilts slightly during the press fitting process, it will be difficult to accurately assemble it into the circlip groove, making assembly more difficult and the assembly effect less than ideal. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a retaining spring press fitter, which aims to solve the problem that the existing press fitter is difficult to assemble and the assembly effect is not very good.

[0005] The utility model adopts the following technical solutions:

[0006] The retaining ring press includes a sleeve, a side wall of the sleeve is provided with a circle of guide grooves, a pressure head is inserted into the top of the sleeve, a guide head is provided at the bottom, a punch is provided at the bottom of the pressure head, the punch is located in the guide head, the pressure head is provided with a guide column corresponding to each guide groove, the guide column is located in the guide groove, and a spring is provided on the punch between the sleeve and the pressure head.

[0007] Furthermore, the bottom of the punch is provided with a cross-shaped notch facing upward, and the punch is provided with interconnected slots above each notch.

[0008] Furthermore, the guide head includes a connecting head, a groove is formed on the connecting head, and a guide head is arranged in the groove.

[0009] Furthermore, a plurality of notches are evenly opened on the top of the pressure head.

[0010] The beneficial effect of the present invention is that when assembling the retaining spring into the retaining spring groove, the staff first holds the retaining spring press in one hand, takes a retaining spring in the other hand and presses the retaining spring slightly, and the retaining spring contracts slightly. Then the staff inserts the retaining spring into the guide head as required, and then the staff inserts the retaining spring press into the through hole of the intermediate shell for a short distance, and finally presses the pressure head downward, and the pressure head drives the punch to move downward to push the retaining spring out of the guide head. The retaining spring recovers its deformation the moment it leaves the guide head and is clamped into the retaining spring groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0018] For the sake of convenience, only the parts related to the embodiments of the present invention are shown.

[0019] Combine Figure 3-5 As shown, the retaining ring press includes a sleeve 1, a guide groove 2 is formed on the side wall of the sleeve 1, a pressing head 3 is inserted into the top of the sleeve 1, a guide head 4 is provided at the bottom, a punch 5 is provided at the bottom of the pressing head 3, and the punch 5 is located in the guide head 4. The pressing head 3 is provided with a guide column 6 corresponding to each guide groove 2, and the guide column 6 is located in the guide groove 2. A spring 7 is provided on the punch 5 between the sleeve and the pressing head 3.

[0020] Turbocharging is usually achieved by using a turbocharger, and the intermediate housing is the core component of the turbocharger. Figure 1As shown, a through hole 81 is opened at the central axis position of the intermediate shell 8, a boss 82 is formed in and above the through hole 81, and a retaining spring groove is opened below the boss 82. The retaining spring press can be used to install the retaining spring 83 in the retaining spring groove.

[0021] like Figure 2 When using a circlip press to assemble the circlip into the circlip groove in the intermediate housing, the staff first holds the circlip press in one hand and takes a circlip with the other hand. At this time, the punch in the circlip press is in its original position, that is, the punch is away from the bottom guide port of the guide head. The staff presses the circlip with a little force, and the circlip shrinks slightly. Then the staff inserts the circlip into the guide head as required, and the circlip is stuck in the guide head. Then insert the circlip press into the through hole of the intermediate housing for a short distance until the boss supports the guide head, and finally press the pressure head downward, which drives the punch to move downward a short distance. The punch moves downward to push the circlip out of the guide head. The moment the circlip is separated from the guide head, it recovers its deformation and is stuck in the circlip groove.

[0022] As the pressure head drives the punch downward, the spring is compressed. Once the circlip is locked into the circlip groove, the operator releases the pressure head, and the spring forces the punch back to its original position. The operator then removes the circlip press from the through-hole. The entire assembly process is relatively simple and ensures precise fit of the circlip into the circlip groove.

[0023] When the worker presses the punch downward, each guide post moves along the height direction of the guide groove. The guide posts and guide grooves play a guiding and limiting role, making the punch more stable during the punching process. At the same time, the guide grooves also play the role of limiting guide posts.

[0024] As a preferred structure, Figure 5 The bottom of the punch 5 is provided with a cross-shaped notch 9, and above each notch 9, a connected slot 10 is provided. The notches divide the punch into four petal heads 11, each of which rests tightly against the inner wall of the guide head. This allows the punch to press the retaining ring more stably, further allowing the retaining ring to be precisely fitted into the retaining ring groove.

[0025] like Figure 2-3 The guide head 4 includes a connector 41 having a groove 42 formed therein, and a guide head 43 disposed within the groove 42. When the operator inserts the retaining spring press into the through-hole of the intermediate housing until the boss supports the guide head, the bottom surface of the connector contacts the top surface of the intermediate housing, and the guide head acts as a limiter.

[0026] In addition, a plurality of notches 12 are evenly formed above the pressing head 3. This makes it easier for the staff to press the pressing head and also makes the retaining spring presser look more beautiful.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
