Description

Technical Field

[0001] This utility model relates to the field of forging inspection technology, and in particular to a non-destructive testing device for ring forgings. Background Technology

[0002] Forging is a processing method that uses forging machinery to apply pressure to a metal billet, causing it to undergo plastic deformation to obtain forgings with specific mechanical properties, shapes, and dimensions. Forging can eliminate defects such as casting porosity that occur during the smelting process, optimize the microstructure, and, because it preserves intact metal flow lines, the mechanical properties of forgings are generally superior to those of castings made of the same material. However, forgings may have internal or surface defects during manufacturing, so non-destructive testing is necessary to ensure quality.

[0003] Currently, existing technologies generally use methods such as ultrasonic testing to inspect forgings. However, when inspecting ring-shaped forgings, operators need to hold the probe and move it around the surface of the ring-shaped forging to ensure the inspection effect. This is relatively troublesome and affects the inspection efficiency.

[0004] Therefore, this application provides a non-destructive testing device for ring forgings to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a non-destructive testing device for ring forgings to solve the problem that the existing ring forgings require operators to hold a probe and move it around the surface of the forging for testing, which is inconvenient.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A non-destructive testing device for ring forgings includes a base, a slidable placement plate on the upper surface of the base, a fixed frame fixed to one end of the base, and an ultrasonic probe elastically mounted on the lower end of the fixed frame for abutting against the upper surface of the placement plate. The ultrasonic probe is connected to an ultrasonic testing device. A fixed seat is fixed in the middle of the upper surface of the placement plate. Multiple horizontally movable abutment posts are inserted around the fixed seat, and a vertical adjusting stud is threaded into the top of the fixed seat. A movable block is threaded in the middle of the adjusting stud and is vertically movable within the fixed seat. Multiple connecting rods are hinged to the edge of the movable block, and the multiple connecting rods are respectively hinged to the ends of the multiple abutment posts.

[0008] Optionally, an adjustment groove is provided on the upper end face of the base, and a screw is rotatably installed in the adjustment groove. One end of the screw extends out of the end of the base and is fixed with a nut.

[0009] Optionally, a slider is fitted at the center of the lower end face of the placement tray. The slider is slidably placed in the adjustment groove, and a screw hole is provided in the center of the slider for the screw to pass through horizontally.

[0010] Optionally, a motor is fixed to the middle of the upper end face of the slider, and the output end of the motor is fixed to the middle of the lower end face of the placement disk, and is used to drive the placement disk to rotate on the upper end face of the base.

[0011] Optionally, the mounting bracket has a C-shaped structure, with a pull rod vertically inserted into the top of the mounting bracket. The lower end of the pull rod extends above the edge of the placement tray and is fixed with the ultrasonic probe.

[0012] Optionally, a spring is fitted onto the pull rod, the spring is fixed to the lower surface of the top surface of the fixing frame, and the lower end of the spring elastically abuts against the ultrasonic probe downwards.

[0013] Optionally, the ultrasonic testing device is fixed on the mounting bracket, and the ultrasonic testing device is connected to the ultrasonic probe via a cable.

[0014] Optionally, each of the abutting posts is fixed with a buffer block for abutting the inner wall of the ring forging at the end away from the fixed seat.

[0015] Optionally, a plurality of vertical limiting guide posts are fixed inside the fixed base. The limiting guide posts penetrate the movable block vertically to form a vertical guide. The adjusting stud is vertically rotatably installed in the middle of the fixed base and threaded through the middle of the movable block to drive the up and down movement of the movable block.

[0016] Optionally, the top of the adjusting stud extends beyond the top of the fixing seat and is secured with a screw cap.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above solution, thanks to the cooperation of the placement plate, the fixed seat abutment post, the movable block, and the adjusting stud, the ring forging can be quickly fixed on the upper surface of the placement plate. The operation is simple and helps to improve the testing efficiency.

[0019] In the above scheme, thanks to the rotating setting of the placement plate, as well as the setting of the fixing frame, ultrasonic probe, and wear-resistant ring, rapid multi-point inspection of the ring forgings fixed on the placement plate can be performed, further improving the inspection efficiency.

[0020] In summary, this device not only facilitates the rapid positioning and fixing of ring forgings, but also enables rapid multi-point testing of the fixed ring forgings, greatly improving the efficiency of non-destructive testing. Attached Figure Description

[0034] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a non-destructive testing device for ring forgings, including a base 1. A slidable placement plate 5 is provided on the upper surface of the base 1 for placing ring forgings. A fixing frame 2 is fixed to one end of the base 1. An ultrasonic probe 3 for abutting the upper surface of the placement plate 5 is elastically installed on the lower end of the fixing frame 2. The ultrasonic probe 3 is connected to an ultrasonic testing device 301, which is fixed to the fixing frame 2 and connected to the ultrasonic probe 3 via a cable.

[0035] Meanwhile, a fixed base 6 is fixed in the middle of the upper end face of the placement plate 5. Multiple horizontally movable abutment posts 7 are inserted around the fixed base 6. A vertical adjusting stud 9 is threaded into the top of the fixed base 6. A movable block 8 is threaded in the middle of the adjusting stud 9. The movable block 8 is vertically movable in the fixed base 6. Multiple connecting rods 801 are hinged to the edge of the movable block 8. The multiple connecting rods 801 are respectively hinged to the ends of the multiple abutment posts 7.

[0036] Each of the abutment posts 7, at the end furthest from the fixed base 6, is fixed with a buffer block 701 for abutting against the inner wall of the ring forging. The fixed base 6 contains multiple vertical limiting guide posts 10, which vertically penetrate the movable block 8, forming a vertical guide. An adjusting stud 9 is vertically rotatably installed in the center of the fixed base 6 and threaded through the center of the movable block 8, driving the up-and-down movement of the movable block 8. Furthermore, the top of the adjusting stud 9 extends beyond the top of the fixed base 6 and is fixed with a cap, allowing the raising and lowering of the movable block 8 to be controlled by rotating the adjusting stud 9. This, in turn, drives the multiple abutment posts 7 to horizontally extend and retract on the side of the fixed base 6 via the connecting rod 801, simultaneously abutting against the inner wall of the ring forging placed on the placement plate 5, thus forming a limiting and fixed position.

[0037] Cooperate Figure 4 As shown, the upper end face of the base 1 is provided with an adjustment groove 101. A screw 102 is rotatably installed in the adjustment groove 101. One end of the screw 102 extends out of the end of the base 1 and is fixed with a screw cap. A slider 501 is fitted in the middle of the lower end face of the placement plate 5. The slider 501 is slidably placed in the adjustment groove 101. A screw hole 502 is provided in the middle of the slider 501 for the screw 102 to pass through horizontally. Therefore, the slider 501 can be driven to move the placement plate 5 horizontally by rotating the screw 102, thereby adjusting the position of the ring forging on the placement plate 5 so that it is located below the ultrasonic probe 3. Ultrasonic detection is then performed by gently pressing the surface of the ring forging with the ultrasonic probe 3.

[0038] Meanwhile, a motor 503 is fixed to the middle of the upper end face of the slider 501. The output end of the motor 503 is fixed to the middle of the lower end face of the placement disk 5 and is used to drive the placement disk 5 to rotate on the upper end face of the base 1. Therefore, the detection position of the ultrasonic probe 3 on the ring forging can be easily changed continuously, which helps to improve the detection efficiency.

[0039] Cooperate Figure 3 As shown, the fixing frame 2 has a C-shaped structure. A pull rod 201 is vertically inserted into the top of the fixing frame 2. The lower end of the pull rod 201 extends to the edge of the placement plate 5 and is fixed with the ultrasonic probe 3. A spring 202 is sleeved on the pull rod 201. The spring 202 is fixed to the lower surface of the top surface of the fixing frame 2. The lower end of the spring 202 elastically abuts against the ultrasonic probe 3, forming an elastic installation.

[0040] The working principle of the technical solution provided by this utility model is as follows:

[0041] When using this non-destructive testing device for ring forgings, the ring forgings can be placed on the upper surface of the placement plate 5. Then, by rotating the adjusting stud 9, the movable block 8 is driven to move down. The connecting rod 801 drives the abutment post 7 to extend out of the bottom of the fixed seat 6 to abut against the inner wall of the ring forgings, thus fixing the ring forgings on the placement plate 5.

[0042] Subsequently, the screw 102 is rotated to drive the slider 501 to translate, which in turn moves the placement plate 5, so that the ring forging can be positioned below the wear ring 4. The ring forging is gently pressed against the upper surface of the ring forging by the elastic force of the spring 202. The motor 503 is started to drive the placement plate 5 to rotate the ring forging, so that the ultrasonic probe 3 can perform rapid multi-point detection on the ring forging.

[0043] In summary, this device not only facilitates the rapid positioning and fixing of ring forgings, but also enables rapid multi-point testing of the fixed ring forgings, greatly improving the efficiency of non-destructive testing.

[0044] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
