An automated detection device for ring forgings

Abstract

This utility model relates to the field of annular forging inspection technology and discloses an automated inspection device for annular forgings, including a worktable. A support is fixedly connected to the worktable, and a motor housing is fixedly connected to the top of the support. This automated inspection device for annular forgings, through the setting of a drive mechanism, allows the workpiece to be fixed during inspection. Then, the drive motor inside the top motor housing is activated, driving the positive and negative lead screws at the ends to rotate. This causes the two threaded plates connected by threads on the surfaces of the positive and negative lead screws to move relative to each other under the limitation of a limiting rod, until the flaw detection probe mounted on the surface of the threaded plate is moved to a suitable position. An ultrasonic flaw detector is then connected to the flaw detection probe via a cable, providing an electrical pulse signal to the probe to excite the emission of ultrasonic waves, thereby achieving the effect of double-sided inspection of the workpiece and avoiding the missed detection problem caused by the limited detection angle and range of traditional single-sided inspection methods.

Description

Technical Field

[0001] This utility model relates to the field of ring forging inspection technology, and in particular to an automated inspection device for ring forgings. Background Technology

[0002] In modern industrial manufacturing, ring forgings are key components widely used in aerospace, automotive manufacturing, energy and power, mechanical engineering, and many other industries. Their quality directly affects the performance, reliability, and safety of related equipment, making high-quality testing of ring forgings extremely urgent.

[0003] Currently, traditional single-sided ultrasonic testing technology is widely used in the inspection of ring forgings. However, this method has significant limitations. Due to the complex structure of ring forgings, the distribution and orientation of internal defects are diverse. During single-sided ultrasonic testing, the ultrasonic beam has a limited propagation path within the workpiece. Defects far from the inspection surface, especially those with large angles to the inspection surface or located in complex structural areas, are easily missed. For example, when inspecting thick-walled ring forgings, tiny cracks near the inner wall on the other side may not be detected by single-sided ultrasonic testing, allowing forgings with potential quality problems to enter the next production stage, creating safety hazards. Therefore, an automated inspection device for ring forgings is proposed. Utility Model Content

Due to the complex structure of ring forgings and the diverse distribution and orientation of internal defects, single-sided ultrasonic testing has a limited propagation path within the workpiece. Defects far from the inspection surface, especially those with large angles to the inspection surface or located in complex structural areas, are easily missed.

The clamping mechanism includes four hydraulic rods fixedly connected to the surface of the upright plates, two of which have a left clamping pad fixedly connected to one side, and the other two hydraulic rods have a right clamping pad fixedly connected to one side.

[0006] As a further embodiment of this utility model, a display module is electrically connected to one side of the ultrasonic flaw detector via a power cord. The display module is fixedly connected to one side of the workbench, and the display module serves to display the test results.

[0007] As a further embodiment of this utility model, a limiting hole is provided on one side of the threaded plate, and a limiting rod is slidably connected inside the limiting hole. The limiting rod serves to limit the position of the threaded plate.

[0008] As a further embodiment of this utility model, threaded holes are provided on both sides of the surface of the support plate, and threaded posts are threadedly connected inside the threaded holes. The threaded posts serve to fix the support plate.

[0009] As a further embodiment of this utility model, the top of the limiting rod is fixedly connected to the bottom of the bracket, and the bottom of the limiting rod is fixedly connected to the top of the workbench. The bracket serves to fix the motor box.

[0012] This utility model provides an automated inspection device for ring forgings, which has the following advantages:

[0013] 1. The automated inspection device for this ring forging, through the setting of the drive mechanism, after the workpiece is fixed in place during inspection, the drive motor inside the top motor box is started. The drive motor drives the positive and negative lead screws at the end to rotate, so that the two threaded plates connected by the threads on the surface of the positive and negative lead screws move relative to each other under the limitation of the limit rod, until the flaw detection probe installed on the surface of the threaded plate is moved to the appropriate position. Then, the ultrasonic flaw detector is connected to the flaw detection probe through the cable, and provides the probe with an electrical pulse signal to excite the emission of ultrasonic waves, thereby achieving the effect of double-sided inspection of the workpiece, avoiding the problem of missed detection caused by the limitation of detection angle and range in the traditional single-sided inspection method.

[0014] 2. The automated inspection device for this ring forging, through the setting of the clamping mechanism, allows the workpiece to be placed in the middle of the left and right clamping pads during use. Then, the hydraulic rods on both sides are activated, which drive the left and right clamping pads to move until the workpiece in the middle is firmly clamped and fixed, thereby achieving the effect of simultaneous inspection of two workpieces. Compared with single-station workpiece inspection, it is more efficient and faster. Attached Figure Description
