Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bladed disk processing equipment, specifically to a tooling for turning integral bladed disks. Background Technology
[0002] Integral bladed disks (IBDs) are key components in aero-engines and gas turbines. They integrate the traditional blades and disk into a single structure, eliminating the need for tenon and slot connections and resulting in a more compact design. IBDs represent a significant innovation in modern aero-engines and gas turbines, offering advantages such as lightweight construction, high efficiency, and high reliability. However, the production of IBDs requires turning processes. Existing turning fixtures for IBDs are complex to operate, lack sufficient clamping and positioning stability, and are not convenient enough to meet production demands. Utility Model Content
[0003] To address the shortcomings of existing integral bladed disk turning fixtures, such as complex operation, insufficient clamping and positioning stability, and inconvenience in use, which fail to meet production needs, this utility model provides an integral bladed disk turning fixture that is simpler to operate, has stronger clamping and positioning stability, and is convenient to use, thus meeting production requirements.
[0004] This utility model provides the following technical solution:
[0005] It includes a base, a support plate and a positioning ring on the top of the base, the positioning ring being press-fitted onto the support plate, the support plate being connected to the base via a column, and an adjusting clamping structure being provided on the support plate within the positioning ring. The adjusting clamping structure includes a pressure plate arranged around the center of the support plate, with double-ended bolts and supports mounted side-by-side on the end face of the pressure plate. The lower parts of the double-ended bolts and supports are inserted into a groove within the support plate. A push rod is fitted onto the double-ended bolt, one end of which extends outwards and passes through the positioning ring.
[0006] Its further features are:
[0007] Supports are provided between the pressure plates. The supports are mounted on the support plate. A guide seat is installed on the end face of the support. The sliding support is arranged in close contact with the end face of the support. A pad is installed on one end face of the sliding support, and the other end is inserted into the guide seat. The sliding support can move axially on the end face of the support. A limiting groove is provided in the middle of the sliding support.
[0008] Corresponding to the support, a limit block is installed on the outer wall of the positioning ring, and the limit block is adjustable;
[0009] Outside the positioning ring, a measuring block and a lifting ring are mounted on the support plate, both of which are arranged around the positioning ring.
[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0011] The pressure plate in the adjusting and pressing structure is equipped with double-headed bolts and supports installed side by side, so that the pressure plate can be height adjusted and moved stably. Push rods are also fitted on the double-headed bolts. After the positioning ring is installed on the impeller, the pressure plate can be pressed against the impeller by pulling the push rod. The operation is simple, the height adjustable pressure plate can press the impeller more accurately, the positioning stability is strong, and the use is convenient and can meet the production needs of enterprises.
[0012] The support and sliding bearing provide support for the bottom of the positioned impeller, preventing the impeller from sinking and deforming, thus further enhancing the stability of the positioning. The pads installed at the ends of the sliding bearing assist in positioning without scratching the support parts.
[0013] The limit block is adjustable and presses and positions the impeller by contacting its outer diameter or inner hole, thereby enhancing the stability of the positioning. Attached Figure Description

[0022] This utility model provides, for example Figure 1This invention relates to a machining fixture for an integral bladed disk, comprising a base 1, a support plate 2 and a positioning ring 3 above the base 1, the positioning ring 3 being press-fitted onto the support plate 2, the support plate 2 being connected to the base 1 via a column 13, and an adjusting clamping structure being provided on the support plate 2 within the positioning ring 3. The adjusting clamping structure includes a pressure plate 11, which is arranged around the center of the support plate 2. Figure 1 In the middle, the number of pressure plates 11 is set to six. Double-headed bolts 14 and supports 9 are installed side by side on the end face of the pressure plates 11. The lower parts of the double-headed bolts 14 and supports 9 are inserted into the sliding groove in the support plate 2. The setting of double-headed bolts 14 makes the vertical height of the pressure plates 11 adjustable. Supports 9 have the function of supporting the pressure plates 11 and making them move stably. Push rods 5 are fitted on the double-headed bolts 14. One end of the push rod 5 extends from the inside to the outside and passes through the positioning ring. The push rod 5 can be pulled outside the positioning ring 3. At this time, the pressure plates 11 move outward and press the impeller against the inner wall of the positioning ring 3.
[0023] See Figure 1 , Figure 5 , Figure 6 Supports 6 are provided between the pressure plates 11. Supports 6 are installed on the support plate 2. Guide seats 7 are installed on the end face of the support 6. The sliding support 8 is arranged in close contact with the end face of the support 6. A pad 10 is installed on one end face of the sliding support 8, and the other end is inserted into the guide seat 7. The sliding support 8 can move axially on the end face of the support 6. A limiting groove is provided in the middle of the sliding support 8. The sliding support 8 can be pressed and positioned by inserting the bolt on the guide seat 7 into the limiting groove. The pad 10 can fit more closely to the bottom of the blade disk to support the blade and prevent the blade disk from sinking and deforming.
[0024] Corresponding to the support 6, a limit block 4 is installed on the outer wall of the positioning ring 3. The limit block 4 is adjustable. The limit block 4 presses and positions the impeller by contacting the outer diameter or inner hole of the impeller positioning. Adjusting the limit block 4 restricts the pressing.
[0025] Outside the positioning ring 3, a measuring block 12 and a lifting ring are installed on the support plate 2. Both the measuring block 12 and the lifting ring are arranged around the positioning ring 3. The measuring block 12 serves as a tool setting reference and has a measurement and comparison function. The lifting ring facilitates the lifting of the tooling. The measuring block 12 and the lifting ring are configured according to requirements. Figure 1 In this configuration, the number of measuring blocks 12 and lifting rings is set to four each.
[0026] Working principle of this utility model:
[0027] When using this utility model, first adjust the sliding support 8 according to the size of the impeller, then place the impeller on the positioning ring 3, adjust the limiting block 4 to press and position the impeller, and then pull the push rod 5 to press the pressure plate 11 to press the impeller onto the positioning ring 3. The clamping stability is high and it is relatively convenient.
