Description

Technical Field

[0001] This utility model relates to the technical field of steel cabinet inspection devices, specifically a multi-angle clamping and positioning device for inspecting weld seams in steel cabinets. Background Technology

[0002] Steel cabinets are widely used in industrial production and daily life. Their welding quality is directly related to the structural strength and safety of the cabinet. Therefore, it is necessary to inspect the welds of steel cabinets.

[0003] The probe head is a core component in the inspection of weld seams in steel cabinets. The piezoelectric crystal inside the probe head vibrates at high frequency under high-voltage pulse excitation, generating ultrasonic waves that are transmitted to the weld seam. When the ultrasonic waves encounter defects such as cracks, pores, or lack of fusion inside the weld seam, some of the sound waves are reflected back to the probe head; if the material is intact, the ultrasonic waves will propagate to the bottom and then reflect. The probe head receives the echo signal, converts it into an electrical signal, and displays it as a waveform. The location and size of the defect can be determined by the echo time difference and amplitude. Currently, inspectors typically use a fixed bracket to simply clamp the probe head and scan the weld seam of the steel cabinet. However, when many weld seams are inside the steel cabinet, it is necessary to hand-hold the probe head to scan the inner space. During operation, the probe head movement is not stable enough, the operation is time-consuming and laborious, and due to space limitations, it is easily obstructed, leading to missed detection locations and poor inspection results. To address the shortcomings of existing technology, this invention provides a multi-angle clamping and positioning device for inspecting weld seams in steel cabinets to solve the above problems.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] This utility model discloses a multi-angle clamping and positioning device for inspecting weld seams in steel cabinets, according to the attached... Figure 1 To be continued Figure 6 As shown, the device includes a guide rail base 1, with several sets of positioning suction cups 2 fixedly connected to the bottom of the guide rail base 1. The positioning suction cups 2 can stably adsorb the entire device onto the surface of the steel cabinet, providing a stable foundation for subsequent testing. An adjustment block 3 is slidably connected to the guide rail base 1, and the adjustment block 3 can slide on the guide rail base 1 to adjust the position.

[0032] According to the appendix Figure 1 and attached Figure 2As shown, further, a ball seat 4 is fixedly connected to the adjusting block 3. The side of the ball seat 4 is provided with a ball groove and a positioning ball 5 is embedded in the ball groove. The positioning ball 5 can rotate at multiple angles in the ball groove. A connecting rod 51 is fixedly connected to the positioning ball 5. A mounting plate 52 for supporting the probe head 6 is provided on the connecting rod 51. The probe head 6 is mounted on the mounting plate 52. The multi-angle rotation of the positioning ball 5 can drive the probe head 6 to be adjusted to a suitable detection angle.

[0033] According to the appendix Figure 4 and attached Figure 6 As shown, furthermore, the ball seat 4 is provided with a clamping and positioning unit 8 for limiting the angle of the positioning ball 5. The clamping and positioning unit 8 includes:

[0034] Sleeve 81 is fixedly connected to ball seat 4;

[0035] The lead screw 82 is threaded into the sleeve 81.

[0036] The locking block 83 is slidably connected inside the sleeve 81 and rotatably connected to the lead screw 82. The locking block 83 is in contact with the positioning ball 5. When it is necessary to fix the angle of the positioning ball 5, the lead screw 82 is rotated. Since the lead screw 82 is threadedly connected to the sleeve 81 and the locking block 83 is slidably connected inside the sleeve 81, the rotation of the lead screw 82 will drive the locking block 83 to move towards the positioning ball 5 until the locking block 83 tightly abuts against the positioning ball 5, thereby achieving the limitation of the angle of the positioning ball 5.

[0037] According to the appendix Figure 6 As shown, a rotating handle 821 is fixedly connected to the lead screw 82. The lead screw 82 can be easily rotated by rotating the handle 821, which improves the ease of operation.

[0038] According to the appendix Figure 6 As shown, a rubber block 831 is provided between the locking block 83 and the positioning ball 5. The rubber block 831 is elastic, which can increase the friction between the locking block 83 and the positioning ball 5, making the positioning ball 5 more secure, and at the same time, it can prevent the locking block 83 from directly contacting the positioning ball 5 and causing wear.

[0039] According to the appendix Figure 1 and attached Figure 3 As shown, the guide rail base 1 is further provided with a drive unit 7 for driving the adjustment block 3 to move. The drive unit 7 includes:

[0040] Motor 71 is fixedly connected to guide rail seat 1;

[0041] A threaded rod 72 is located at the output end of the motor 71 and is threadedly connected to the adjusting block 3. When the motor 71 is started, the motor 71 drives the threaded rod 72 to rotate. Since the adjusting block 3 is slidably connected to the guide rail seat 1 and threadedly connected to the threaded rod 72, the rotation of the threaded rod 72 will cause the adjusting block 3 to slide on the guide rail seat 1, thereby realizing the automatic adjustment of the position of the adjusting block 3.

[0042] Furthermore, the guide rail base 1 is equipped with a power module 711 for supplying power to the motor 71. A switch is installed on the cable between the power module 711 and the motor 71, and the switch is located on the guide rail base 1. The power module 711 supplies power to the motor 71, and the switch can control the start and stop of the motor 71, making it convenient for operators to control the device.

[0043] According to the appendix Figure 1 To be continued Figure 6 As shown, this device achieves stable fixation through the positioning suction cup 2, and uses the driving unit 7 to drive the adjustment block 3 to move. Combined with the multi-angle rotation of the positioning ball 5 and the limiting of the angle of the positioning ball 5 by the clamping positioning unit 8, the position and angle of the probe head 6 can be flexibly adjusted to meet the inspection needs of welds in different positions of the steel cabinet.

[0044] According to the appendix Figure 2 To be continued Figure 6 As shown, the clamping and positioning unit 8 achieves the fixation of the angle of the positioning ball 5 through a simple mechanical structure, which is easy to operate, and the setting of the rubber block 831 improves the stability of the fixation and the protection of the positioning ball 5.

[0045] According to the appendix Figure 1 To be continued Figure 6 As shown, it is particularly important to emphasize that the drive unit 7 uses a combination of motor 71 and threaded rod 72 to realize the automatic movement of adjustment block 3, which improves the automation level and working efficiency of the device. Motor 71 can rotate bidirectionally through a switch to realize the bidirectional movement of probe head 6, and the movement process is smooth and uniform, ensuring the detection effect of probe head 6.

[0046] The working principle of the multi-angle clamping and positioning device for inspecting weld seams in this steel cabinet is as follows:

[0047] The device is attached to the inside or outside of the steel cabinet using the positioning suction cup 2. The motor 71 is started, and the motor 71 drives the threaded rod 72 to rotate, causing the adjusting block 3 to slide on the guide rail seat 1 to a suitable position. The positioning ball 5 is rotated to adjust the probe head 6 to a suitable detection angle. The rotating handle 821 is rotated, causing the lead screw 82 to move the locking block 83 towards the positioning ball 5 until the locking block 83 is tightly pressed against the positioning ball 5 by the rubber block 831, fixing the angle of the positioning ball 5. At this time, the inspection of the weld seams of the steel cabinet can begin.

[0048] The operating steps for this multi-angle clamping and positioning device for inspecting weld seams in steel cabinets are as follows:

[0049] The device is placed near the weld to be inspected on the steel cabinet, and the device is attached to the surface of the steel cabinet by the positioning suction cup 2.

[0050] Rotate the positioning ball 5 and adjust the angle of the probe head 6 to accurately detect the position of the weld.

[0051] Rotate the handle 821 to fix the angle of the positioning ball 5 using the clamping and positioning unit 8.

[0052] Start the motor 71, and use the drive unit 7 to move the adjusting block 3 to the appropriate position.

[0053] The inspection of the welds on the steel cabinet has begun.

[0054] The multi-angle clamping and positioning device for inspecting weld seams in steel cabinets offers the following advantages:

[0055] The device is stably fixed by the positioning suction cup 2, which is easy to operate and facilitates quick adsorption and positioning when inspecting the weld seams inside the steel cabinet.

[0056] The drive unit 7 can automatically drive the adjustment block 3 to move, which improves the automation level and work efficiency of the device and reduces the labor intensity of manual operation.

[0057] The multi-angle rotation of the positioning ball 5 and the flexible fixing of the angle of the positioning ball 5 by the clamping and positioning unit 8 can meet the inspection requirements of welds at different positions and angles of steel cabinets, and improve the accuracy and comprehensiveness of the inspection.

[0058] The rubber block 831 increases the friction between the locking block 83 and the positioning ball 5, making the positioning ball 5 more secure and protecting it from wear, thus extending the service life of the device.
