Description

The utility model relates to the field of non-destructive testing and can be used for manual ultrasonic testing of parts of gas turbine engines, such as high-pressure compressor blades, fan blades, hood flaps, fairings, etc.

A device for non-destructive testing is known (FR 3075380, IPC F01D 5/12; G01N 29/14, publ. 01/17/2020), containing a swivel joint, which is taken as a prototype. The levers are connected to each other and the sensors are fastened to the levers.

The disadvantage of the prototype is the presence in the design of hinged joints, as well as a leveling device, leading to the complexity of operation and manufacture of the device due to the presence of complex designs of hinges and sliding supports (sliding joint). In addition, there is a constructive and technological complexity of fastening and positioning of measuring elements. At the same time, the number of these components is large, which negatively affects its cost and reliability. Together, all this reduces the reliability of work and positioning accuracy.

Thus, the technical problem is a large number of hinged and sliding joints in the prototype, as well as inaccurate alignment of the measuring elements, which reduces the reliability of the device and measurement inaccuracy.

The technical problem is to exclude hinged and sliding elements, as well as a leveling device, from the design, thereby obtaining a more reliable device design.

The technical result is to increase reliability by simplifying the design.

The technical result is achieved due to the fact that in the device for non-destructive testing of a part (workpiece) defect, containing a movable and a fixed bracket, according to the utility model, the fixed bracket is made integral with the handle, on which there is a rack with a linear guide and a lever mechanism, while the lever mechanism the mechanism contains a Y-shaped block, a push handle, a rod and a frame of the lever mechanism, at the same time the movable bracket is connected to the linear guide by means of a carriage inside which an elastic element is installed, in addition, additionally movable and fixed brackets are made with the possibility of installing sensors in them control through the clamps, while the handle of the fixed bracket, the movable bracket and the stand are made with grooves (for laying wires from control sensors) closed by a lid.

In addition, according to the utility model, a carrying handle is additionally installed, which is attached to the stand and the handle with screws.

In addition, according to the utility model, the movable and fixed brackets are made with curved surfaces.

As in the prototype, the device contains a movable and fixed arms.

In the proposed utility model, in contrast to the prototype, the implementation of the fixed bracket integrally with the handle allows you to reduce the number of moving parts and simplify the design.

The location of the rack with linear guide and lever mechanism on the handle allows for ergonomic use.

The implementation of the lever mechanism with a Y-shaped block, as well as the push handle, rod and frame of the lever mechanism, allows for manual movement of the carriage at a specified distance, and the implementation of the block with a Y-shaped block allows you to raise the carriage without distortions.

The movable arm is connected to the linear guide by means of a carriage, which ensures precise linear movement. At the same time, an elastic element is installed inside the carriage, which allows you to shift the movable bracket to the fixed bracket (return means for bringing the control sensors to each other).

Movable and fixed brackets are made with the possibility of installing control sensors in them through clamps, this design allows the use of various control sensors, for example, ultrasonic piezoelectric transducers (PEP) according to GOST R 55725-2013, contact with a soft or hard protector, for example, P111- 2.5-K12, P111-2.5-P12, P111-2-P12-PRKM, P111-0.8-6, immersion, for example, P211-15 (IPL1506), P211-10 (IPV1010) with local immersion bubbler or waterbox type tub, rolling eg RP25HS-1 (Sonatest) or other types of sensors depending on control tasks. Thus, the scope of the device is expanded by installing different designs of control sensors.

In addition, the movable and fixed brackets can be made with curved surfaces corresponding to the curvature of the tested part (not shown) to provide inspection access in confined spaces.

The utility model, by simplifying the design and expanding the scope of this device, makes it possible to generally increase the reliability of the entire device.

At the same time, the handle of the fixed bracket, the movable bracket and the stand are made with grooves (for laying wires from control sensors) closed with a lid, which allow protecting the wires from damage while working with the device and ensuring the safety of the operator, since with proper organization of the wires, the danger of damaging them disappears. imprudence.

The device for non-destructive testing of a part defect contains (Fig. 1) a fixed bracket 1, made integral with the handle 2. The lever mechanism 3, the rack 4 and the handle 5 are mounted on the handle 2, fastening is carried out using screws (not shown). The lever mechanism 3 consists of a Y-shaped block 6, a frame of the lever mechanism 7, a rod 8, a push handle 9. The elements of the lever mechanism are interconnected by shafts 10. A linear guide 11 and a handle 5 are fixed on the rack 4, fastening is carried out using screws (not shown). A carriage 12 with a movable bracket 13 is fixed on the linear guide 11. The Y-shaped block 6 is connected to the carriage 12 through the axle 14 and the anti-friction bushing 15.

In the carriage 12, a hole 16 is made (Fig. 2), in which the elastic element 17 is located. When you press the push handle 9 through the traction system 8 and the frame of the lever mechanism 7, the Y-shaped block 6 is transferred to the movement, together with the carriage 12 through the axis 14 and anti-friction sleeve 15. To return the non-destructive testing device to its original position, it is necessary to remove the pressure from the push handle 9, and the elastic element 17 will create a force sufficient to return the structure to its original position.

A groove 18 with two holes 19 and 20 is made in the movable bracket 13, and is closed with a cover 21.

In the fixed bracket 1, which is integral with the handle 2, a groove 22 is made for the entire length and closed with a lid 23.

The rack 4 has a groove 24, which is aligned with the groove 22. The grooves 18, 22, 24 allow you to lay the wires from the control sensors.

In the fixed bracket 1 and in the movable bracket 13, a universal groove 25 is made for installing a clamp 26 with control sensors (Fig. 1, 2, 3). Clamp 26 with a universal groove 25 allows you to install contact probes with a soft or hard protector and immersion probes with a local bubbler or waterbox type bath, for example, P111-2.5-K12, P111-2.5-P12, P111-2-P12-PRKM , P111-0.8-6, P211-15 (IPL1506), P211-10 (IPV1010) or similar in design, as well as rolling transducers or other types and types of sensors, depending on the type of control. Thus, the universal groove 25 makes it possible to manufacture clamp 26 for any design of the control sensor, depending on the task. In FIG. 4 and 5 show fragments of the device with curved surfaces (without position) of the movable 27 and fixed 28 brackets, corresponding to the curvature of the tested part (not shown).

The non-destructive testing device works as follows. Installed on a fixed bracket 1, in a universal groove 25, clamp 26 with a control sensor. Wires are led out from the control sensor through the groove 22. Then they install on the movable bracket 13, in the universal groove 25, the clamp 26 with the control sensor. Further, through hole 19, groove 18, hole 20, groove 24 and groove 22, the wires from the control sensor are led out, then the grooves 18 and 22 are closed with covers 21 and 23. The wires from the control sensors are connected to the recording equipment (not shown). They bring the device to the controlled part (not shown) and press the push handle 9, raising the movable bracket 13, and thereby ensure the installation of the controlled part between the control sensors, then remove the pressure from the push handle 9, and the elastic element 17 tightly compresses the sensors control with the controlled part, and perform the control. After the control is completed, press the push handle 9 and remove the device from the controlled part and remove the pressure from the push handle 9 (the elastic element 17 will create a force sufficient to return the structure to its original position).

Thus, the implementation of the proposed utility model with the above distinctive features, in conjunction with the known features, by simplifying the design and expanding the scope of this device, in general, improves the reliability of the entire device.
