[0007] S3: Fitting the annular groove and the annular boss together, so that the metal plate and the insulating plate are inlaid as one, and screwing screws into the fitting part between the annular groove and the annular boss;

[0008] S4: The countersunk hole of the screw is sealed with glue, and the plate embedded as one is subjected to secondary processing by cutting, and the metal plate and the outer edge area of ​​the fitting part of the annular groove and the annular boss are cut off to obtain the slip ring body.

[0009] Optionally, also include:

[0010] S10: fixing the two plates on a processing machine respectively, and processing the front and back surfaces of the two plates to be flat;

[0011] Optionally, the metal plate is a brass plate;

[0012] Optionally, AB glue is used for potting:

[0013] Optionally, the plate is made of metal;

[0014] Optionally, the spacings between adjacent annular grooves are equal, and the spacings between adjacent annular bosses are equal to the spacings between the annular grooves.

[0015] The overall inlay process of a CT medical slip ring provided by the present invention is based on a plate of metal material and a plate of insulating material, and a plurality of concentric annular grooves are formed on the metal plate, and a plurality of concentric annular bosses are formed on the insulating plate at the same time; the number and positions of the annular bosses correspond to the annular grooves; then, based on the fitting of the annular grooves and the annular bosses, the two plates are inlaid as one, and the fitting part is reinforced with screws; finally, after the countersunk holes of the screws are potted, the countersunk holes of the screws are potted with glue, and secondary cutting processing is performed to obtain a slip ring disc body.

[0016] Compared with the prior art, there is no need to open a separate mold for the slip ring disc body, which greatly saves manufacturing costs; at the same time, the annular groove and the annular boss have high coaxiality, which can ensure the quality and precision of the finished product.

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] In one embodiment, a CT medical slip ring integral inlay process is provided, and its main process is as follows: Figure 1 As shown, and includes the following steps:

[0031] S1: Prepare two plates of preset sizes, one of which is a metal plate and the other is an insulating plate.

[0032] The plate is used as the raw material for the finished product. The metal plate 1 is preferably a copper plate, and the insulating plate 2 is not limited. Specifically, the size and shape of the plate can be arbitrary, such as Figure 2 Rectangular sheet material shown.

[0033] S2: Processing a plurality of concentric annular grooves on the front side of the metal plate, and processing a plurality of annular bosses corresponding to the number and positions of the annular grooves on the front side of the insulating plate.

[0034] like Figures 3 to 6 As shown, the annular grooves 3 and the annular bosses 4 correspond in number and position so that the two fit together and the two plates can be inlaid. The spacing between adjacent annular grooves is equal, and the spacing between adjacent annular bosses is equal to the spacing between annular grooves to meet the needs of the slip ring body wire groove, but the width and depth can also be flexibly set.

[0035] Furthermore, before processing the grooves and bosses, the two plates are processed to be flat; specifically, the two plates are fixed on processing machines respectively, and both the front and back surfaces of the two plates are processed to be flat.

[0036] S3: Fit the annular groove and the annular boss together to embed the metal plate and the insulating plate into one, and screw into the fitting part between the annular groove and the annular boss with screws.

[0037] When the annular groove and the annular boss are fitted together, screws 5 are driven into the fitting parts of the two to fasten the two plates together, facilitating subsequent secondary processing.

[0038] S4: The countersunk holes of the screws are sealed with glue, and the inlaid plates are subjected to secondary processing by cutting, and the metal plates and the outer edge areas of the fitting parts of the annular groove and the annular boss are cut off to obtain the slip ring body.

[0039] Specifically, AB glue can be used for potting, but is not limited thereto; Figure 7 As shown in FIG. 1 , the plate after potting is subjected to secondary processing, and is cut along the cutting position 7. The slip ring disc body obtained after the secondary processing is as follows: Figure 8 As shown, the front and back of the slip ring disc are as follows Fig. 9 , 10 shown.

[0040] The above is an explanation of the overall inlay process of the CT medical slip ring of the present invention, which is used to help understand the present invention; however, the implementation mode of the present invention is not limited to the above-mentioned embodiments, and any changes, modifications, substitutions, combinations, and simplifications made without departing from the principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
