[0035] In the embodiment, as shown in Figure 1 and Figure 2 , the housing positioning assembly comprises a bottom plate 8, a positioning cylinder 7 and a positioning sleeve 6, the positioning cylinder 7 is installed on the bottom plate 8, the bottom of the housing 54 is sleeved in the positioning cylinder 7, and the top of the housing 54 is sleeved in the positioning sleeve 6, the diameter of the central through hole of the positioning sleeve 6 matches the diameter of the central through hole of the housing 54, asFigure 9 As shown in the figure, the top of the positioning sleeve 6 is provided with a tapered hole 61, the opening diameter of the tapered hole 61 is larger than the diameter of the ring 51, and the tail diameter of the tapered hole 61 is smaller than the diameter of the ring 51; the gantry 18 is installed on the bottom plate 8, and the pressing shaft 1 is coaxially arranged with the positioning sleeve 6. During installation, after the shell positioning assembly and the pressing assembly are installed, the spring and the washer 52 are sequentially installed into the positioning sleeve 6, and then the ring 51 is placed into the tapered hole 61, and then the pressing assembly is lowered, thereby clamping the ring 51 in the clamping groove 53.

[0036] In the embodiment, the number of the convex ribs 14 corresponds to the number of the installation grooves 32 of the clamping jaw assembly 3, and the clearance gap 15 through which the ball 34 can pass is formed between two adjacent convex ribs 14. Preferably, the number of the installation grooves 32 is four, and thus the number of the convex ribs 14 is also four. When the ball 34 passes through the guide inclined surface 16 and enters the inner cavity of the pressing cylinder 2, the pressing cylinder 2 is rotated so that the ball 34 is aligned with the clearance gap 15, thereby taking out the installation disc 31 from the pressing cylinder 2.

[0038] In the embodiment, as shown in the figure, Figure 2 The bottom of the pressing shaft 1 is provided with a convex hemispherical body. The hemispherical body and the top of the pressing shaft 1 form a limiting step. Preferably, the diameter of the hemispherical body is larger than the diameter of the inner circle of the washer 52.

Moreover, the pressing shaft 1 drives the ring 51 to descend during the descending process. The ring 51 and the washer 52 do not contact during the initial descending process. When the ring 51 enters the clamping groove 53, the washer 52 ascends under the action of the elastic restoring force of the spring and abuts against the ring 51 after the pressing shaft 1 ascends.

[0039] In the embodiment, as shown in the figure, Figure 9As shown, the bottom of the center through hole of the positioning sleeve 6 is a mounting hole 62 which is radially outwardly extended, and the top of the shell 54 is fitted and mounted in the mounting hole 62, so as to facilitate the assembly of the shell 54 and the positioning sleeve 6, and through the cooperation of the shell 54 and the mounting hole 62, the coaxiality of the shell 54 and the positioning sleeve 6 can be ensured.
