As shown in fig. 4 to 7, the embodiment provides a pressing and positioning mechanism for a turbine shell tooling, which includes a driving mechanism, a transmission rod 300 and a pressing plate 400. The driving mechanism is connected with the first end of the transmission rod 300, the second end of the transmission rod 300 is connected with the pressing plate 400, the pressing plate 400 is arranged on one side of the transmission rod 300, the transmission rod 300 is used for being sleeved in the small-end exhaust hole 107 of the turbine shell 100, the pressing plate 400 is used for being arranged on the end face 110 of the small-end exhaust hole of the turbine shell 100, and the radial width of the pressing plate 400 is smaller than that of the small-end exhaust hole 107 of the turbine shell 100, so that the pressing plate 400 can penetrate through the small-end exhaust hole 107 of the turbine shell 100.
The driving mechanism is used for driving the pressure plate 400 to move through the transmission rod 300, so that the pressure plate 400 rotates to the position of the end surface 110 of the small-end exhaust hole of the turbine shell 100 and presses the end surface 110 of the small-end exhaust hole of the turbine shell 100, or the pressure plate 400 rotates to the position where the pressure plate 400 can pass through the small-end exhaust hole 107 of the turbine shell 100.
It is understood that the phrase "the radial width of the pressure plate 400 is smaller than the radial width of the small end exhaust hole 107 of the turbine shell 100 so that the pressure plate 400 can pass through the small end exhaust hole 107 of the turbine shell 100" means that the pressure plate 400 can pass through the small end exhaust hole 107 when the pressure plate 400 is moved to a proper position in the radial direction of the small end exhaust hole 107, so as to facilitate the disassembly or assembly of the turbine shell 100.
When the pressing and positioning mechanism for the turbine shell tooling of the embodiment is used, the turbine shell 100 is firstly sleeved on the transmission rod 300 through the pressing plate 400 in the direction shown in fig. 2, and one end of the transmission rod 300 close to the pressing plate 400 is eccentrically arranged with the small-end exhaust hole 107 of the turbine shell 100, wherein the side surface of the impeller end 105 of the turbine shell 100 is located at the lower side, and the lower side surface is a positioning surface 108 and is attached to the positioning surface on the supporting seat 510. Then, the driving mechanism drives the transmission rod 300 to rotate, so that the pressing plate 400 moves to the end surface 110 of the small-end exhaust hole of the turbine shell 100, and the driving mechanism drives the transmission rod 300 to move downwards again, so that the pressing plate 400 is pressed on the end surface 110 of the small-end exhaust hole of the turbine shell 100; at this time, the positioning surface 108 of the turbine shell 100 can be tightly attached to the positioning surface of the support seat 510, and the related processing of the turbine shell 100 can be started. After the machining is completed, the driving mechanism drives the transmission rod 300 to move upwards, so that the pressing plate 400 is far away from the end surface 110 of the small-end exhaust hole of the turbine shell 100, then the driving mechanism acts again to rotate the pressing plate 400 to a position where the pressing plate 400 can pass through the small-end exhaust hole 107 of the turbine shell 100, and the turbine shell 100 can be detached from the transmission rod 300.
The pressing plate 400 of the turbine shell tooling pressing and positioning mechanism of the embodiment is arranged on one side of the transmission rod 300, so that when the transmission rod 300 is eccentrically arranged with the shaft hole of the small-end exhaust hole 107 of the turbine shell 100, the transmission rod 300 rotates to enable the pressing plate 400 to be on the end surface 110 of the small-end exhaust hole, and the pressing plate 400 can also move to one side of the center of the small-end exhaust hole 107. The pressure plate 400 presses the turbine casing when it is on the end surface 110 of the small end exhaust hole, and the pressure plate 400 is moved to the side of the center of the small end exhaust hole 107 (i.e. the position opposite to the small end exhaust hole) so that the pressure plate 400 passes through the small end exhaust hole 107 of the turbine casing 100. Since the end surface 110 of the small-end exhaust hole does not generally expand outward relative to the impeller end 105 side as compared to the outer circumferential end surface 109 of the large-end exhaust hole 106, a suitable flattening position is generally found in which, when a pressure perpendicular to the end surface 110 of the small-end exhaust hole is applied to the end surface 110 of the small-end exhaust hole, the line of action of the pressure can pass through a stable range of the positioning surface 108, so that the turbine casing 100 is not deflected relative to the positioning surface 108.

The anti-collision component of the pressing plate 400 is a copper block, and the soft property of the copper block is also utilized to prevent collision. That is, when the turbine shell collides with the pressing piece or the copper block, the copper material is soft, so the copper material is deformed by collision, and hard collision damage cannot occur to the turbine shell.
