Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention 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 merely illustrative of the invention and do not limit the invention.

In one embodiment, a CT medical slip ring casting process is provided, which has a main flow shown in fig. 1 and includes the following steps:

s1: a panel of a predetermined size is prepared.

The plate is used as a raw material of a finished product, and the plate is preferably made of a metal material, particularly a copper plate. Specifically, a rectangular plate material as shown in fig. 2 may be selected.

S2: fixing the plate on a processing machine table, and processing the front surface and the back surface of the plate to be smooth.

The plate 1 is processed, fixed on a processing machine table, and the front and back surfaces of the plate are processed to be smooth, so that subsequent grooving is facilitated.

S3: and processing a plurality of concentric annular grooves on the front surface of the plate.

As shown in fig. 3 and 4, the front surface of the plate is selected, and a plurality of concentric annular grooves 2 are formed on the front surface of the plate by a processing machine. The distance between the adjacent annular grooves can be equal or unequal according to actual requirements; meanwhile, the annular grooves have certain depth, but do not penetrate through the plate, and the depth can be equal or unequal.

Further, after step S3 and before step S4, a step is further included

S30: at least one reinforcing rib crossing the grooves is additionally and fixedly arranged at the position vertical to the tangential direction of the grooves.

Wherein, the strengthening rib 3 will also be buried in the colloid at the encapsulating in-process to the setting is in the position perpendicular with the tangential direction of recess, plays the effect of guaranteeing that encapsulating in-process loop line recess is indeformable. Understandably, when the reinforcing ribs are uniformly distributed on the loop wire grooves, the disk body can be stressed uniformly and is not easy to deform.

One specific implementation of the reinforcing rib is shown in fig. 5 and 6, wherein the reinforcing rib is made of glass fiber plate, and the loop line grooves are fixed in a crossed manner to play an optimal fastening role, and the method specifically includes the following steps:

s301: uniformly fixing a preset number of first glass fiber plates on the odd annular grooves through screws;

s302: and the second glass fiber plates with the preset number are uniformly fixed on the even annular grooves through screws.

The number of the first glass fiber plate and the number of the second glass fiber plate are 6, and the first glass fiber plate and the second glass fiber plate are uniformly distributed on the loop line groove; the first glass fiber plate is fastened on the odd annular groove, such as

rings

1, 3, 5, 7 and 9, by using 6M 4 screws 31; the second glass fiber sheet is fastened to the double annular grooves, such as 2, 4, 5, 6, 10 rings, with 6M 4 screws 31. Therefore, the first glass fiber plate, the second glass fiber plate and the first glass fiber plate are sequentially fixed around the annular groove in a circle.

S4: and a preset inner baffle and a preset outer baffle are used for enclosing a circular ring-shaped region to be subjected to glue pouring, wherein the area difference between the outer baffle and the inner baffle corresponds to the circular ring-shaped region to be subjected to glue pouring.

The area to be filled with glue is circular and all the circular grooves are included. The inner baffle 4 and the outer baffle 5 which are preset are prepared in advance, the area difference between the inner baffle and the outer baffle just corresponds to the circular ring-shaped region to be filled with glue, the region to be filled with glue is isolated from the plate, and the filling of glue is facilitated without affecting other regions.

The size, the shape and the shielding mode of the inner baffle plate and the outer baffle plate can be flexible and various. In one implementation, as shown in fig. 7, the preset inner and outer baffles are both circular, and the following steps are adopted:

s41: and covering a preset inner baffle on one surface of the plate by taking the circle center of the annular groove as the circle center, fixing the preset inner baffle by using bolts, and enabling the outer edge of the preset inner baffle to correspond to the inner edge of the annular glue filling area.

S42: and covering the other side of the inner baffle with a preset outer baffle by taking the circle center of the annular groove as the circle center, and fixing the preset outer baffle with the plate by using bolts so that the outer edge of the preset outer baffle corresponds to the outer edge of the annular glue filling area.

Namely, from the both sides of panel, it is fixed with panel that circular shape inside and outside baffle passes through bolt 6 respectively, simultaneously, the centre of a circle that inside and outside baffle all used the annular groove is the centre of a circle, forms the concentric circles and forms annular region (corresponding the area of waiting to glue filling promptly) between the two, the follow-up encapsulating of being convenient for. The inner and outer baffles may be made of PVC, PC or PE, but are not limited thereto.

S5: and (5) performing glue filling on the area to be subjected to glue filling, and cutting off the area outside the annular area to be subjected to glue filling to obtain the slip ring disc body.

The glue filling adopts the modulated AB glue 7, but is not limited to the above; the tray body after glue filling is carried out on the area to be glue filled is shown in figure 8. And after the glue filling is finished, the disc body is regarded as a whole to be subjected to multi-surface cutting processing, and a required structure is obtained.

Specifically, as shown in fig. 9, an area outside the annular area to be filled with glue is cut along the cutting processing station 8 to obtain a slip ring disc body, and the processed finished product is shown in fig. 10 and 11.

The above is the explanation of the casting process of the CT medical slip ring of the present invention, which is used to help understand the present invention; the present invention is not limited to the above embodiments, and any changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit of the present invention are intended to be equivalent replacements within the scope of the present invention.
