Description

Technical Field

[0001] This utility model relates to the field of turbine processing equipment technology, and in particular to a fixture for machining the worm end of a turbine housing. Background Technology

[0002] A turbine is a fan in a car or airplane engine. It uses exhaust gas to blow fuel vapor into the engine to improve engine performance. A turbine is a rotary power machine that converts the energy of a flowing working fluid into mechanical work. When machining a turbine housing, a fixture is needed to hold it. Current fixtures for machining turbine housings typically use cylinders or similar devices to drive positioning blocks and plates to clamp and limit the turbine housing. To facilitate adjusting the position of the positioning plate and other components for turbine housings of different sizes, grooves are usually made on the surface of the base. Inside the grooves, sliders connected to cylinders and positioning plates slide, and bolts pass through the sliders to connect them to the base for limiting their position. However, current bases usually have multiple grooves, sliders, and cylinders, requiring adjustments to be made one by one, and specific tools are needed to tighten the bolts one by one. This operation method is quite cumbersome. Utility Model Content

[0003] This invention provides a fixture for machining the worm end of a turbine housing, which solves the problems in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fixture for machining the worm end of a turbine housing includes a mounting base. Vertical plates are arranged equidistantly in a ring at the top of the mounting base, and a first cylinder is installed inside the vertical plates. One end of the first cylinder is connected to a positioning block, and a placement platform is provided at the center of the top of the mounting base.

[0006] The top of the mounting base is provided with a sliding groove at equal intervals in an annular shape, and a slider is slidably connected inside the sliding groove. The top of the slider is symmetrically provided with a first partition plate, and a positioning plate is hinged to the surface of the first partition plate. The top of the slider is hinged to a second cylinder that is hinged to the bottom of the positioning plate.

[0007] The mounting base has an adjustment component installed inside.

[0008] With the above structure, the positioning plate hinged at the top of the second cylinder can be flipped and moved by the operation of the second cylinder, so as to limit the surface of the annular boss at the turbine housing opening. By the operation of the first cylinder, the positioning block at one end can be moved to the surface of the turbine housing, so as to limit the turbine housing again.

[0009] The adjustment assembly includes a first rotating rod rotatably connected to the bottom of the mounting base, and a first gear connected to the surface of the first rotating rod. A second rotating rod is rotatably connected to the center of the bottom of the mounting base, and a second gear meshing with the first gear is connected to the surface of the second rotating rod. A first bevel gear is also connected to the surface of the second rotating rod. A second partition is circumferentially and equidistantly arranged at the bottom of the mounting base, and a screw is rotatably connected to the surface of the second partition. The screw passes through the second partition and is connected to a second bevel gear meshing with the first bevel gear. A connecting block connected to the bottom of the slider is threaded onto the surface of the screw.

[0010] With the above structure, the rotation of the first rotating rod causes the first gear to rotate on the surface of the second gear, so that the second gear drives the first bevel gear on the surface of the second rotating rod to rotate on the surface of the second bevel gear, thereby causing the second bevel gear to drive the screw to rotate, so that the connecting block on the surface of the screw can drive the slider, the second cylinder and the positioning plate to move, which can be adjusted according to different sizes of turbine housings.

[0011] The first rotating rod passes through the mounting base and is connected to a knob.

[0012] The above structure allows the knob to rotate, which in turn drives the first rotating rod and the first gear.

[0013] The surface of the second rotating rod is equipped with a bearing, and the surface of the bearing is connected equidistantly with fixed rods that are connected to the inner wall of the mounting base.

[0014] The above structure facilitates the support and limiting of the second rotating rod through bearings and fixing rods.

[0015] A collection box is bolted to the bottom of the mounting base.

[0016] The above structure facilitates the collection box to collect debris that falls into the mounting base through the chute, and also makes it easy to disassemble the collection box to maintain the components at the bottom of the mounting base.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] In this invention, the rotation of the first rotating rod and the first gear enables the second gear to drive the second rotating rod, the first bevel gear, the second bevel gear, and the screw to rotate. This allows the connecting block on the screw surface to move the slider, the second cylinder, and the positioning plate. The distance between each positioning plate can be adjusted according to the size of the turbine housing, eliminating the need for individual adjustments and limiting their positions. The operation is relatively simple. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 2 A jig for machining the worm end of a turbine housing includes a mounting base 1. Multiple vertical plates 2 are equidistantly arranged in a ring at the top of the mounting base 1. A first cylinder 3 is installed inside each vertical plate 2. The output end of the first cylinder 3 is connected to a positioning block 4, allowing the positioning block 4 to be moved to the surface of the turbine housing for positioning by the operation of the first cylinder 3. A placement platform for placing the turbine housing is installed at the center of the top of the mounting base 1. To further position the turbine housing, a sliding groove 5 is formed at the top of the mounting base 1. A sliding mechanism is slidably connected inside the sliding groove 5. Block 6 is designed to facilitate the adjustment of the second cylinder 9, etc. The top of the slider 6 is provided with a first partition 7, and a rotating shaft is connected between the first partitions 7. The surface of the rotating shaft is connected to a positioning plate 8. The top of the slider 6 is also hinged to the second cylinder 9. The output end of the second cylinder 9 is hinged to the bottom end of the positioning plate 8, so that by working the second cylinder 9, the positioning plate 8 hinged at its top can be rotated and moved by the rotating shaft, so that one side of the bottom end of the positioning plate 8 can be moved to the surface of the annular boss at the turbine housing opening, thereby limiting the turbine housing again.

[0026] Furthermore, to facilitate the adjustment of the second cylinder 9 and the positioning plate 8, a first rotating rod 10 is installed at the bottom of the mounting base 1. The surface of the first rotating rod 10 is connected to the first gear 11. A second rotating rod 12 is connected to the center of the bottom of the mounting base 1. The surface of the second rotating rod 12 is connected to the second gear 13 and the first bevel gear 14, which are connected to the first gear 11. A second partition plate 15 is equidistantly arranged in a ring at the bottom of the mounting base 1. The second partition plate 15 is located on the front and rear sides of the bottom of the slide groove 5. A screw 16 is connected between the two parts. The surface of the screw 16 is connected to a second bevel gear 17 connected to the first bevel gear 14 and a connecting block 18 connected to the slider 6. When the first rotating rod 10 drives the first gear 11 to rotate, the second gear 13 can drive the second rotating rod 12, the first bevel gear 14, the second bevel gear 17 and the screw 16 to rotate. The connecting block 18 on the surface of the screw 16 can drive the slider 6 to move within the slide groove 5, thereby allowing the second cylinder 9 and the positioning plate 8 at the top of the slider 6 to move.

[0027] Furthermore, in order to ensure that the first rotating rod 10 can be rotated outside the mounting base 1, the first rotating rod 10 needs to pass through the top of the mounting base 1 and be connected to a knob, so that the first rotating rod 10 and the first gear 11 can be driven to rotate by rotating the knob.

[0028] Furthermore, in order to maintain the stability of the second rotating rod 12, a bearing 19 needs to be installed on the surface of the second rotating rod 12, and a fixing rod 20 is provided on the surface of the bearing 19 so that the other end of the fixing rod 20 is connected to the inner wall of the mounting base 1. The mounting base 1 is composed of a circular plate and an annular plate.

[0029] Furthermore, in order to maintain or repair the components at the bottom of the mounting base 1, a collection box 21 needs to be bolted to the bottom of the mounting base 1. The collection box 21 facilitates the collection of debris that falls into the mounting base 1 through the slide groove 5. At the same time, the collection box 21 can be disassembled to facilitate the maintenance of the components at the bottom of the mounting base 1.

[0030] The working principle is as follows: the opening of the turbine housing is placed on the top of the placement platform, and the first cylinder 3 is driven to work, so that the positioning block 4 connected to one end of the first cylinder 3 moves to the surface of the turbine housing and limits its movement. At the same time, the second cylinder 9 is also driven to work, so that the positioning plate 8 hinged at its top can be flipped and moved, so that one side of the bottom of the positioning plate 8 can be moved to the surface of the annular boss at the opening of the turbine housing, which can limit the turbine housing again. If the position of the positioning plate 8 needs to be adjusted, the knob can be turned, which can drive the first rotating rod 10 and the first gear 11 to rotate. This causes the second gear 13 connected to the surface of the first gear 11 to drive the second rotating rod 12 and the first bevel gear 14 to rotate. The rotation of the first bevel gear 14 causes the second bevel gear 17 connected to its surface to rotate and the screw 16 to rotate, so that the connecting block 18 on the surface of the screw 16 can drive the slider 6, the second cylinder 9, and the positioning plate 8 to move and limit their movement. This allows for adjustment according to the size of the turbine housing, and the operation is simple.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
