Description

Technical Field

[0001] The utility model belongs to the technical field of compressor blade production, and in particular relates to a five-axis machining center for a compressor blade production line. Background Art

[0002] The compressor is a component of a gas turbine engine that uses high-speed rotating blades to work on the air to increase the air pressure. The front end of the compressor impeller blade is curved and is called the guide wheel. Its function is to guide the gas into the working impeller without impact, reducing the impact loss of the airflow.

[0003] When processing compressor blades, the existing five-axis machining center often clamps the compressor blades through a chuck, which requires manual clamping, and the compressor blades after clamping are also unstable and easy to fall off during processing. This phenomenon has become a problem that needs to be solved urgently by people in this field. Utility Model Content

[0004] The utility model aims to provide a five-axis machining center for a compressor blade production line to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a five-axis machining center for a compressor blade production line, comprising a housing and a machining mechanism, wherein the machining mechanism is arranged inside the housing, the machining mechanism comprises a machining part and a workpiece mounting part, and the workpiece mounting part comprises a base, a motor, a rotating rod and a clamping member;

[0006] The base is fixedly mounted on the bottom of the inner wall of the shell, the motor is fixedly mounted above the base, and the rotating rod is fixedly connected to the output end of the motor;

[0007] The clamping member is arranged above the rotating rod, and the processing portion is arranged above the clamping member.

[0008] The utility model further describes that the clamping member includes a placement plate and four clamping mechanisms, and the four clamping mechanisms each include a slide rail, a slider, a clamping block, a telescopic rod, and an external hydraulic pump;

[0009] The slide rail is fixedly installed above the placement plate, the slider is slidably connected to the inner wall of the slide rail, the telescopic rod is fixedly installed on the outer side of the inner wall of the slide rail, and the inner end of the telescopic rod is fixedly connected to the slider;

[0010] The clamping block is fixedly installed above the sliding block, and the telescopic rod is connected to an external hydraulic pump pipeline.

[0011] The utility model further describes that the upper surface of the base and the lower surface of the placement plate are both equipped with bearing seats, and a guide column is connected between the two bearing seats.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: the workpiece mounting portion adopted by the utility model, the operator places the compressor blade between the four clamping blocks, and then drives the five-axis machining center to run, the external hydraulic pump injects hydraulic oil into the four telescopic rods synchronously, so that the four telescopic rods are synchronously extended, and the four telescopic rods drive the slider to slide inward along the inner wall of the slide rail, thereby driving the four clamping blocks to approach each other until the inner side of the clamping block contacts the outer surface of the compressor blade and squeezes it to fully fix the compressor blade, with high fixing strength, and compared with the traditional method of fixing with a chuck, it is more convenient and efficient, and the synchronous fixation can also ensure that the compressor blade is concentric with the processing part, and only the Z-axis knife is needed, and the X-axis and Y-axis knives are not needed, and the processing efficiency can be greatly improved. At the same time, during the rotation of the placement plate, the bearing seat below the placement plate and the bearing seat above the base make the guide column rotate around the center, which can improve the connection strength between the base and the placement plate, thereby improving the stability of the placement plate during rotation, and preventing the compressor blade from being subjected to excessive force during processing, causing the placement plate to shake and affect the processing quality.

[0018] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3The utility model provides a technical solution: a five-axis machining center for a compressor blade production line, comprising a housing 1 and a machining mechanism, the machining mechanism being arranged inside the housing 1, the machining mechanism comprising a machining part and a workpiece mounting part, the workpiece mounting part comprising a base 2, a motor 3, a rotating rod 4 and a clamping member;

[0020] The base 2 is fixedly mounted on the bottom of the inner wall of the housing 1, the motor 3 is fixedly mounted above the base 2, and the rotating rod 4 is fixedly connected to the output end of the motor 3;

[0021] The clamping member is arranged above the rotating rod 4, and the processing portion is arranged above the clamping member;

[0022] The clamping member includes a placement plate 5 and four clamping mechanisms, each of which includes a slide rail 6, a slider 7, a clamping block 8, a telescopic rod 9 and an external hydraulic pump;

[0023] The slide rail 6 is fixedly installed above the placement plate 5, the slider 7 is slidably connected to the inner wall of the slide rail 6, the telescopic rod 9 is fixedly installed on the outer side of the inner wall of the slide rail 6, and the inner end of the telescopic rod 9 is fixedly connected to the slider 7;

[0024] The clamping block 8 is fixedly installed above the slide block 7, and the telescopic rod 9 is connected to the external hydraulic pump pipeline;

[0025] The operator places the compressor blade between the four clamping blocks 8, and then drives the five-axis machining center to run. The external hydraulic pump injects hydraulic oil into the four telescopic rods 9 synchronously, so that the four telescopic rods 9 extend synchronously. The four telescopic rods 9 drive the slider 7 to slide inward along the inner wall of the slide rail 6, thereby driving the four clamping blocks 8 to approach each other until the inner side of the clamping block 8 contacts the outer surface of the compressor blade and squeezes it to fully fix the compressor blade. The fixing strength is high, and compared with the traditional method of fixing with a chuck, it is more convenient and efficient. Synchronous fixing can also ensure that the compressor blade is concentric with the processing part, and only the Z-axis knife is needed, and the X-axis and Y-axis knives are not needed, so the processing efficiency can be greatly improved;

[0026] The upper surface of the base 2 and the lower surface of the placement plate 5 are both equipped with bearing seats 10, and a guide column 11 is connected between the two bearing seats 10;

[0027] During the rotation of the mounting plate 5, the bearing seat 10 below the mounting plate 5 and the bearing seat 10 above the base 2 allow the guide column 11 to rotate around the center, which can improve the connection strength between the base 2 and the mounting plate 5, thereby improving the stability of the mounting plate 5 during rotation and preventing the compressor blades from being subjected to excessive force during processing, causing the mounting plate 5 to shake and affecting the processing quality.
