Description

Technical Field

[0001] The utility model relates to the technical field of volute production, in particular to a volute casting gate cutting device. Background Art

[0002] A turbocharger is essentially an air compressor that increases intake air volume by compressing air. It uses the inertial force of the engine's exhaust gas to drive the turbine inside the turbine chamber. The turbine, in turn, drives the coaxial impeller, which pressurizes air sent from the air filter duct and pressurizes it into the cylinder.

[0003] Turbocharger volutes are generally produced by casting. During mass production, they are generally produced using the lost wax method. Castings are often made in pairs, with a gate in the middle. After the casting is cooled, a cutting device is required to remove the gate on the surface of the volute. Existing cutting methods are not reliable for clamping the volute, and can easily cause the cut to tilt. In addition, only one side of the volute can be cut at a time, which is very inconvenient and inefficient. Utility Model Content

[0023] Specifically, the cutting device 2 includes a mounting plate 21, a guide rail 22, an equipment frame 23, a sliding seat 24, a transmission shaft 25, a first pulley 26, a cutting blade 27, a motor 28, a second pulley 29, a belt 210, a cylinder seat 211 and a first cylinder 212. The mounting plate 21 is fixedly arranged on the upper surface of the mounting frame 1 and is arranged on the outside of both sides of the clamping device 3. The guide rail 22 is mounted on the upper surface of the mounting plate 21, the equipment frame 23 is clamped on the top of the guide rail 22, the sliding seat 24 is mounted on the bottom of the equipment frame 23, the transmission shaft 25 is movably connected to the top of the equipment frame 23, the first pulley 26 and the cutting blade 27 are respectively fixedly arranged at both ends of the transmission shaft 25, the motor 28 is arranged on the upper surface of the mounting plate 21, and the second pulley 29 is mounted on the motor 2 8 output end, the belt 210 is sleeved on the outside of the first pulley 26 and the second pulley 29, the cylinder seat 211 is fixedly arranged on the upper surface of the mounting plate 21, the first cylinder 212 is installed on the outside of the cylinder seat 211, the output end of the first cylinder 212 passes through and extends to the inside of one side of the cylinder seat 211, and its telescopic end is fixed to the side of the equipment frame 23, and a sliding groove that cooperates with the guide rail 22 is provided at the bottom of the sliding seat 24.
