Description
TECHNICAL FIELD
[0001] The utility model relates to a positioning fixture. Specifically speaking, it is the positioning device for fixing turbocharger shell when processing the pipe orifice of turbocharger shell (hereinafter referred to as turbocharger shell). BACKGROUND
[0002] It is known in the turbocharger shell production industry that the turbocharger shell is spiral-shaped, and the air inlet needs to be positioned during processing to prevent shaking during processing and affect the processing quality. The traditional method is to support the air inlet port of the turbocharger shell on one side, and to press the opposite side of the air inlet port with a push cylinder to achieve angular positioning of the turbocharger shell. The air outlet port of the turbocharger shell is supported by a centering shaft core to position the air outlet. Because the shape of the air inlet port of the turbocharger shell is irregular, the push cylinder needs to find a suitable pressing position. If the pressing position of the push cylinder is not suitable, the positioning will not be firm, affecting the processing precision and making it difficult to ensure product quality.
[0003] The utility model solves the problem of providing a positioning mechanism for processing the pipe orifice of a turbocharger shell. This positioning mechanism can improve processing precision and product quality. UTILITY MODEL CONTENTS
[0004] The problem to be solved by the utility model is solved by the following technical solutions:
[0005] The positioning mechanism for processing the pipe orifice of a turbocharger shell of the utility model comprises a base, which is a cuboid arranged horizontally, and a positioning seat connected to the front side of the left end of the base. A cylinder seat is connected to the rear side of the right end of the base, and a zero-degree corner cylinder is connected to the left side of the cylinder seat. The zero-degree corner cylinder is arranged horizontally, with the outer end of its piston rod facing the left end of the base and a vertical rod connected to it. There is a horizontal shallow groove in the middle of the top surface of the base, and a support and a lever cylinder are connected to the upper and lower sides of the front side of the base corresponding to the horizontal shallow groove. The air inlet end of the turbocharger shell being processed faces outward, and the pressing rod of the lever cylinder presses on the shell below the air inlet end. The support is on the side wall of the turbocharger shell on the opposite side of the air outlet end. An angular support is connected to one side of the positioning seat adjacent to the turbocharger shell, and the angular support is on the air inlet end side of the turbocharger shell. There is a pressing plate between the upper end of the vertical rod and the turbocharger shell, a vertical shaft is connected to the bottom of the horizontal shallow groove, and the middle of the pressing plate is rotatably connected to the vertical shaft. The pressing plate and the vertical rod are rotatably connected, and the other end has a bent end bent towards the air inlet end side, which presses on the outer wall of the turbocharger shell inside the air inlet end.
[0006] The vertical rod contains a vertical plate, the lower end of which is connected with the outer end of the piston rod of the zero-degree rotary cylinder, and the upper end of which is connected with a rotating shaft.
[0007] Further improvement of the utility model is that the positioning seat is plate-shaped, one side of which is fixed on the upper surface of the left end of the base, and the other side of which extends outside the front side of the base, and the support is located on the corresponding side of the part of the positioning seat extending outside the front side of the base.
[0008] Further improvement of the utility model is that the pressing plate is provided with a cover plate, one pair of opposite sides of which are fixed on the two sides respectively, and the other pair of opposite sides of which are flush with the two side surfaces of the base.
[0009] As can be seen from the above scheme, the turbine housing outlet end is positioned by the angular support first being pressed on the turbine housing side wall opposite the outlet end. Then, the zero-degree rotary cylinder is started, and the piston rod and the vertical rod integrated with the piston rod are extended and retracted, thereby driving the pressing plate to rotate around the rotating shaft and the vertical shaft by an angle, so that the end of the pressing plate with the bent end is pressed on the turbine housing outer wall inside the inlet end, realizing the angular positioning of the turbine housing. At the same time, the pressing rod of the lever cylinder is pressed on the housing below the turbine housing outlet end. Compared with the background art, the positioning is firm, the machining precision is improved, and the product quality is ensured. BRIEF DESCRIPTION OF DRAWINGS
