Description

Technical Field

[0001] The utility model relates to the technical field of turbine shell processing, in particular to a turbine shell grinding device. Background Art

[0002] Turbines are widely used in the automotive and aviation fields. Turbines are a type of rotary power machine that converts the energy of a flowing fluid into mechanical work, which can improve the power performance of an engine. When making a turbine, it is inevitable to grind the turbine shell, so a fixture and grinding device that can stably clamp the turbine shell are required.

[0003] The utility model with authorization announcement number CN214292431U discloses a hydraulic clamp for a turbine shell that is easy to clamp. The utility model drives an arc-shaped clamping plate to move toward the middle through hydraulic cylinders relatively arranged in a fixing part, thereby achieving a clamping effect on the turbine shell.

[0004] The above device can achieve the purpose of clamping the turbine shell, but the hydraulic cylinder cannot accurately apply appropriate pressure to the turbine shell. When the pressure is high, it will cause damage to the turbine shell, and when the pressure is low, the turbine shell cannot be clamped. In addition, the friction between the arc-shaped clamping plate and the turbine shell cannot fix the turbine shell. Utility Model Content

[0005] The purpose of the utility model is to provide a turbine casing grinding device to solve the problems raised in the above background technology.

[0013] As a further solution of the utility model: a rubber pad is arranged on the inner side of the arc block.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The first linear slide rail enables the mobile fixed structure to move horizontally on the slide rail, and the rodless cylinder enables the mobile grinding structure to move vertically along the slide rod. At the same time, the sealing strip on the hatch makes the inside of the box a relatively sealed space. The operating status inside the box can be well observed through the hatch. When an accident occurs during grinding, the device can be closed in time. In addition, the inside of the box is relatively closed, so that the dust is sealed inside the box, which protects the health of the user.

[0016] 2. The first fixed block, the grinder and the grinding head are moved longitudinally by the second linear slide rail, so that the turbine housing can be well ground in the longitudinal direction. At the same time, the grinding head can be replaced, which is convenient for replacing grinding heads with different grinding meshes, so as to achieve the set grinding standard;

[0017] 3. The friction between the turbine housing and the rubber pad is increased to prevent the turbine housing from displacement during grinding. At the same time, the limit block, spring and connecting rod cooperate to apply the initial clamping force to the arc block, and the cylinder applies the secondary clamping force to the slide seat, thereby providing a stable clamping force for the turbine housing.
