[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0031] The following is combined with Figure 1 and Figure 2 A turntable assembly provided by the utility model is described in detail. The turntable assembly can be used for the tooling of helium sealing inspection of die-cast aluminum parts such as aluminum covers.

[0032] The turntable assembly 1 includes a turntable 10 , a transition piece 20 , a sealing piece 30 and a pressure plate 40 .

[0033] Specifically, the outer ring of the turntable 10 is provided with a supporting base plate 110, and the supporting base plate 110 has a first channel 111 running through it in the thickness direction; the transition piece 20 is placed on the supporting base plate 110 and is provided with a smooth surface, and the transition piece 20 has a second channel 201 running through it in the thickness direction, and the second channel 201 is communicated with the first channel 111; the bottom of the sealing piece 30 is in close contact with the smooth surface of the transition piece 20, and the sealing piece 30 has a third channel 301 running through it in the thickness direction, and the third channel 301 is communicated with the second channel 201 to construct a detection channel, and the aluminum cover 2 to be tested is placed on the sealing piece 30 and covers the third channel 301; the pressing plate 40 is arranged on the sealing piece 30 and is connected to the supporting base plate 110 to press the transition piece 20 and the sealing piece 30.

[0034] That is to say, compared with the existing grinding and polishing on the base plate, the present embodiment adopts a transition piece 20 with a smooth surface for assembling the seal 30 to improve the sealing effect of the detection channel, so that the detection channel can be evacuated into a vacuum area, which is beneficial to the helium sealing detection, wherein the transition piece 20 with a smooth surface can utilize the characteristics of the material of the transition piece 20 itself so that the flatness of its smooth surface meets the design requirements.

[0035] Therefore, according to a turntable assembly 1 of an embodiment of the utility model, a transition piece 20 is set, and the transition piece 20 has a smooth surface, which can make the bottom of the seal 30 fit tightly, thereby improving the sealing effect. The sealing effect is 2-3 times higher than that of the existing solution, and there is no need to grind the supporting bottom plate 110; through the cooperation of the pressure plate 40, the transition piece 20 and the seal 30 can be pressed, which is convenient for replacing accessories.

[0036] The turntable 10 may be connected to the support base plate 110 using spoke-shaped connecting rods.

[0037] In order to improve efficiency, the support base plate 110 is annular or arc-shaped and is arranged around the axis of the turntable 10. The support base plate 110 is circumferentially provided with at least two first channels 111, and each first channel 111 is correspondingly provided with a transition piece 20 and a sealing piece 30. In other words, at least two detection channels can be distributed circumferentially of the turntable 10 to perform sealing detection synchronously and improve efficiency.

[0038] Specifically, there are multiple pressure plates 40 , and one pressure plate 40 is arranged between two adjacent detection channels, so that the transition piece 20 and the sealing piece 30 can be better assembled on the supporting bottom plate 110 .

[0039] More specifically, the pressing plate 40 is connected to the supporting base plate 110 and presses the transition piece 20 and the sealing piece 30 through fasteners. It is understandable that the fasteners can be inserted from the pressing plate 40, pass through the sealing piece 30 and the transition piece 20 in sequence, and then connect to the supporting base plate 110. For example, the fasteners are bolts and nuts. After the bolts are inserted from the pressing plate 40, they pass through the sealing piece 30, the transition piece 20, and the supporting base plate 110 in sequence, and then are fastened with nuts. In this way, the fasteners are used for assembly, which facilitates the simple replacement of accessories such as the sealing piece 30.

[0040] In some examples, the sealing member 30 is a rubber member. The transition member 20 is a glass plate or an acrylic plate. Due to the material properties of the glass plate or the acrylic plate, the side thereof in contact with the sealing member 30 has good flatness, that is, a smooth surface.

[0041] In addition, the sealing member 30 and the transition member 20 have the same shape as the supporting base plate 110 .

[0042] The transition piece 20 is integrally formed or formed by splicing a plurality of arc-shaped plates. The sealing piece 30 is assembled from a plurality of arc-shaped rubber pieces, so as to facilitate the replacement of damaged rubber pieces.
