Description

Technical Field

[0001] This utility model relates to the field of shaft workpiece inspection technology; more specifically, it relates to an ultrasonic inspection device for shaft workpieces. Background Technology

[0002] Inspection of shaft components is crucial in manufacturing, playing a vital role in multiple ways. By precisely measuring dimensions, shape, positional tolerances, and surface roughness, inspection ensures that shafts fully conform to design drawings, which is fundamental to guaranteeing proper assembly and functionality of the shafts with related parts. Simultaneously, it effectively detects potential problems such as material defects (cracks, porosity) and improper heat treatment, preventing equipment failures and downtime due to early fatigue, excessive wear, or sudden fracture, thus ensuring the safety and reliability of equipment operation. A rigorous inspection system significantly extends the service life of shafts and the entire equipment, avoiding high repair and replacement costs caused by the failure of a single part, as well as potential downtime and recall losses. It is a key link in controlling product quality and improving production efficiency.

[0003] Current technologies primarily rely on contact measurement, specialized gauges, and precision platform measurements. Automated production lines are often equipped with specialized inspection tools or simple sensors. Surface defects are mainly detected visually, using fluorescent magnetic particle testing or eddy current testing, while internal structures rely on ultrasonic or X-ray testing.

[0004] During the production of wheel and axle, flaw detection is required, necessitating the use of an ultrasonic flaw detector for vertical flaw detection. However, some existing devices require workers to hold the device and operate it around the wheel and axle during inspection, which is inconvenient and increases the workload of workers. Therefore, there is an urgent need for an ultrasonic testing device for shaft workpieces to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an ultrasonic testing device for shaft-type workpieces to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an ultrasonic testing device for shaft-type workpieces, comprising:

[0007] The main structure includes a fixed base and a first cylinder;

[0008] The support structure has two sets, and the support structure includes a second cylinder and a limiting seat, and both sets of second cylinders are installed on the upper surface of the fixed base.

[0009] Preferably, both ends of the upper surface of the fixed base are fixedly connected to support plates, and a pneumatic three-jaw chuck is connected to the internal bearing of a set of support plates. A first motor is installed on the outer surface of a set of support plates, and the output end of the first motor is fixedly connected to one end of the pneumatic three-jaw chuck. An external power supply can provide power to the pneumatic three-jaw chuck and the first motor respectively. After the pneumatic three-jaw chuck is started, it can clamp one end of the workpiece. After the first motor is started, it can drive the pneumatic three-jaw chuck and the workpiece to rotate synchronously.

[0010] Preferably, the other set of support plates is internally threaded with a first lead screw, and one end of the first lead screw is connected to a limit plate by a bearing. The other end of the first lead screw is provided with a throttle handle, which allows the operator to rotate the first lead screw more easily. When the first lead screw rotates, it can move inside the other set of support plates and drive the limit plate to move, so that the limit plate can be used to clamp and fix workpieces of different lengths.

[0011] Preferably, a support rod is fixedly connected to the upper end of the opposite side surface of the two sets of support plates, and a connecting seat is sleeved on the outer surface of the support rod. A first cylinder is installed on the lower surface of the connecting seat. A detection probe is installed on the piston rod of the first cylinder. An external power source can provide power to the first cylinder and the detection probe. After the first cylinder is started, its internal piston rod will push the detection probe to move longitudinally, so that the detection probe can better fit the outer surface of the workpiece.

[0012] Preferably, a second motor is mounted on the outer surface of another set of support plates, and a second lead screw is fixedly connected to the output end of the second motor. One end of the second lead screw is connected to the inside of a set of support plates by a bearing. The second lead screw is internally threaded to the middle position of the connecting seat. The other end of the second lead screw is connected to a fixed seat by a bearing. The fixed seat is fixedly connected to the upper end of the inner surface of a set of support plates. An external power supply can provide power to the second motor and the detection probe. After the second motor starts, it will drive the second lead screw to rotate. When the second lead screw rotates, it will drive the connecting seat and the first cylinder to move laterally. The fixed seat can improve the stability of the second lead screw during rotation.

[0013] Preferably, a support seat is fixedly connected to the piston rod of the second cylinder, and a connecting shaft is fixedly connected inside the support seat. The connecting shaft is provided in multiple sets, and nylon rollers are hinged to the outer surfaces of the multiple sets of connecting shafts. The two sets of limiting seats are fixedly connected to the upper surface of the fixed base. An external power supply can provide power to the second cylinder and the detection probe. After the second cylinder is started, its internal piston rod will push the support seat to move longitudinally. At this time, the multiple sets of nylon rollers can be driven to fit against the outer surface of the workpiece.

[0014] Preferably, both ends of the lower surface of the support are fixedly connected to limit rods, and the limit rods are inserted into the inside of the limit seat. The setting of two sets of limit rods and limit seats can limit the support and prevent the support from shifting or rotating during use.

[0015] The technical effects and advantages of this utility model are as follows: The pneumatic three-jaw chuck of this utility model can clamp one end of a shaft-type workpiece. Rotating the first lead screw can drive the limiting plate to fit against the other end of the workpiece, thus fixing the workpiece. After the first motor is started, it can drive the pneumatic three-jaw chuck to rotate slowly in sync with the workpiece. Starting the second motor and the first cylinder can drive the detection probe to automatically detect the workpiece. This design can effectively reduce the workload of the staff during detection and can improve the efficiency of detection to a certain extent.

[0016] By activating the two sets of second cylinders, the two sets of support seats can be moved longitudinally, which can drive multiple sets of nylon rollers to fit against the outer surface of the workpiece. At this time, the multiple sets of nylon rollers can support the workpiece. This design can prevent shaft-type workpieces from deforming and jumping due to their own weight, and can improve the stability of the workpiece during rotation, thereby improving the accuracy of the test results.

A first motor 14 is mounted on the outer surface of one set of support plates 12, and the output end of the first motor 14 is fixedly connected to one end of the pneumatic three-jaw chuck 13. A first lead screw 15 is threadedly connected to the internal thread of another set of support plates 12, and a limit plate 16 is connected to one end of the first lead screw 15. Support rods 17 are fixedly connected to the upper ends of opposite sides of the two sets of support plates 12. A connecting seat 18 is fitted onto the outer surface of the support rod 17, and a first cylinder 19 is mounted on the lower surface of the connecting seat 18. A detection probe is mounted on the piston rod of the first cylinder 19. A second motor 110 is mounted on the outer surface of another set of support plates 12, and a second lead screw 111 is fixedly connected to the output end of the second motor 110. One end of the second lead screw 111 is bearing-connected to the inside of a set of support plates 12, and the second lead screw 111 is internally threaded to the connecting seat 18 at the middle position. The other end of the second lead screw 111 is bearing-connected to a fixed seat 112, and the fixed seat 112 is fixedly connected to the upper end of the inner surface of a set of support plates 12. An external power supply can be used to supply power to the support plates 12. The pneumatic three-jaw chuck 13 and the first motor 14 provide power. After starting, the pneumatic three-jaw chuck 13 can clamp one end of the workpiece. After starting, the first motor 14 can drive the pneumatic three-jaw chuck 13 and the workpiece to rotate slowly in sync. The other end of the first lead screw 15 is equipped with a throttle handle, making it easier for the operator to rotate the first lead screw 15. When rotating, the first lead screw 15 can move inside another set of support plates 12, and will drive the limit plate 16 to move, so that the limit plate 16 can be used to clamp and fix workpieces of different lengths. An external power supply can provide power to the first cylinder 19 and the detection probe. The first cylinder 19 starts... After activation, the internal piston rod pushes the detection probe to move longitudinally, allowing the detection probe to better fit the outer surface of the workpiece. An external power supply can provide power to the second motor 110 and the detection probe. After the second motor 110 starts, it drives the second lead screw 111 to rotate. When the second lead screw 111 rotates, it drives the connecting seat 18 and the first cylinder 19 to move laterally. The fixed seat 112 can improve the stability of the second lead screw 111 during rotation. This design allows the entire detection process to be automated, thereby effectively reducing the workload of the operator during detection and improving the efficiency of detection to a certain extent.

[0026] Example 2

[0027] like Figures 1 to 4 As shown, this embodiment also proposes: a support structure 2, which has two sets, and includes a second cylinder 21 and a limiting seat 26.

Limiting rods 25 are fixedly connected to both ends of the lower surface of the support seat 22, and the limiting rods 25 are inserted into the inside of the limiting seat 26. The second cylinder can be powered by an external power source. The cylinder 21 and the detection probe provide a power source. After the second cylinder 21 is started, its internal piston rod will push the support seat 22 to move longitudinally. At this time, it can drive multiple sets of nylon rollers 24 to fit against the outer surface of the workpiece. The multiple sets of nylon rollers 24 can support the workpiece. This design can prevent the shaft workpiece from deforming and jumping due to its own weight, and can improve the stability of the workpiece during rotation, thereby improving the accuracy of the detection results. The setting of two sets of limit rods 25 and limit seats 26 can limit the support seat 22, which can prevent the support seat 22 from shifting or rotating during use, thereby further improving the stability of the detection process.

[0029] Working principle: When using the equipment, first insert one end of the workpiece into the pneumatic three-jaw chuck 13, then start the pneumatic three-jaw chuck 13 to clamp it. Then rotate the first lead screw 15 to drive the limit plate 16 to fit against the other end of the workpiece. Next, start the two sets of second cylinders 21 to drive multiple sets of nylon rollers 24 to fit against the outer surface of the workpiece. At this time, the position of the workpiece can be fixed. Then start the second motor 110 to drive the connecting seat 18 and the first cylinder 19 to move to one end of the workpiece. Then start the first motor 14 to drive the workpiece to rotate slowly. Then start the first cylinder 19 to push the detection probe close to the outer surface of the workpiece for ultrasonic testing. During the testing process, the connecting seat 18 and the detection probe can slowly move towards the other end of the workpiece with the rotation of the second lead screw 111, forming a spiral scanning path. At this time, the workpiece can be tested. The above is the complete working principle of this utility model.
