Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to a non-destructive testing device for vehicle parts. Background Technology

[0002] With the development of the times, cars have become a common means of transportation in daily family life. A car is assembled from many delicate parts. Once there are damaged parts, they need to be dealt with in time to reduce safety hazards.

[0003] Once a part is bumped or used for a long time, cracks are likely to appear on its surface. However, the cracks on the surface of the part are generally small and difficult to observe directly. Therefore, it is necessary to use flaw detection equipment for inspection. During inspection, the flaw detection head is held by hand to inspect the part. Due to the unevenness of the part surface, uneven pressure or unstable movement speed during manual operation, the contact between the probe and the part is unstable, which reduces the inspection effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as uneven pressure or unstable movement speed during manual operation, and unstable contact between the probe and the parts, which reduces the detection effect. Therefore, this invention proposes a non-destructive testing device for vehicle parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a non-destructive testing device for vehicle parts, including a support platform, a fixed frame fixedly connected to the upper end of the support platform, a movable frame slidably connected to the fixed frame, a movable plate slidably connected to the movable frame, an electric telescopic rod fixedly connected to the upper end of the movable frame to drive the movable plate to move vertically, a fixed cylinder fixedly connected to the bottom end of the movable plate, a movable block slidably connected inside the fixed cylinder, a spring fixedly connected to the upper end of the movable block, one end of the spring fixedly connected to the fixed cylinder, and a flaw detector head connected to the bottom end of the movable block.

[0007] Preferably, the mounting bracket is coated with an anti-corrosion layer.

[0008] Preferably, the movable frame is connected to an air-purging mechanism for cleaning the flaw detector head. The air-purging mechanism includes a miniature air pump, which is fixedly connected to the movable frame. The air outlet of the miniature air pump is connected to a first connecting pipe. One end of the first connecting pipe is sealed and inserted into a movable pipe. The movable pipe is connected to the first connecting pipe through a limiting member. The bottom end of the movable pipe is connected to a second connecting pipe. One end of the second connecting pipe is connected to a circular annular pipe. The flaw detector head passes through the circular annular pipe. The bottom end of the circular annular pipe is connected to an exhaust pipe. The outlet end of the exhaust pipe is inclined upward towards the bottom end of the flaw detector head.

[0009] Preferably, the active tube and the second connecting tube are an integral structure.

[0010] Preferably, the exhaust pipe has several parts that are evenly distributed along the axis of the annular pipe.

[0011] Preferably, the limiting member includes a connecting rod, one end of which is rotatably connected to the movable tube, and the other end of which is fixedly connected to a retaining seat, which engages with the first connecting tube.

[0012] Preferably, the connecting rod is fitted with an anti-slip sleeve.

[0013] Preferably, a limiting ring is fixedly connected to the first connecting pipe, and the bottom end of the card holder is in contact with the upper end of the limiting ring.

[0014] The non-destructive testing device for vehicle parts proposed in this utility model has the following advantages:

[0015] After the flaw detector head contacts the automotive part, it pushes the movable block upward. The movable block moves upward and squeezes the spring. The spring is compressed and generates elastic force, which makes the flaw detector head make close contact with the automotive part. During the horizontal movement of the flaw detector head, when it encounters a protruding part, it can squeeze the spring and move upward. The elastic force generated by the spring keeps the flaw detector head in close contact with the automotive part. The contact between the flaw detector head and the part is stable, thereby improving the inspection effect. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: Refer to Figure 1-3 A non-destructive testing device for vehicle parts includes a support platform 1, a fixed frame 2 fixedly connected to the upper end of the support platform 1, the fixed frame 2 being coated with an anti-corrosion layer, a movable frame 3 slidably connected to the fixed frame 2, a horizontal adjustment component 4 connected to the fixed frame 2 to drive the movable frame 3 to move horizontally, a movable plate 5 slidably connected to the movable frame 3, an electric telescopic rod 6 fixedly connected to the upper end of the movable frame 3 to drive the movable plate 5 to move vertically, a fixed cylinder 7 fixedly connected to the bottom end of the movable plate 5, a movable block 8 slidably connected inside the fixed cylinder 7, a spring 9 fixedly connected to the upper end of the movable block 8, one end of the spring 9 fixedly connected to the inside of the fixed cylinder 7, and a flaw detection head 10 connected to the bottom end of the movable block 8.

[0024] Work process:

[0025] The automotive parts are placed on the support platform 1 and fixed. After the electric telescopic rod 6 is powered on, it drives the movable plate 5 to move downward a set distance. The movable plate 5 drives the fixed cylinder 7 to move downward. The fixed cylinder 7 drives the flaw detector 10 to move downward a set distance through the movable block 8. After the flaw detector 10 contacts the automotive parts, it pushes the movable block 8 upward. After the movable block 8 moves upward, it squeezes the spring 9. The spring 9 is compressed and generates elastic force. The elastic force generated by the spring 9 makes the flaw detector 10 make close contact with the automotive parts.

[0026] After the horizontal adjustment component 4 is activated, it drives the movable frame 3 to move in the horizontal direction, thereby causing the flaw detector head 10 to move in the horizontal direction. During the horizontal movement of the flaw detector head 10, when it encounters a protruding part, it can squeeze the spring 9 to move upward. The elastic force generated by the spring 9 keeps the flaw detector head 10 in close contact with the automotive parts. The flaw detector head 10 makes stable contact with the parts, thereby improving the detection effect.

[0027] Example 2: After prolonged contact with vehicle parts, debris adheres to the bottom of the flaw detector 10, affecting the detection effect. (Refer to...) Figure 4-5 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the movable frame 3 is connected to an air-purifying mechanism 11 for cleaning the flaw detector head 10. The air-purifying mechanism 11 includes a micro air pump 111, which is fixedly connected to the movable frame 3. The air outlet of the micro air pump 111 is connected to a first connecting pipe 112. One end of the first connecting pipe 112 is sealed and inserted into a movable pipe 113. The movable pipe 113 is connected to the first connecting pipe 112 through a limiting member. The bottom end of the movable pipe 113 is connected to a second connecting pipe 114. The movable pipe 113 and the second connecting pipe 114 are an integral structure. One end of the second connecting pipe 114 is connected to a circular pipe 115. The flaw detector head 10 passes through the circular pipe 115. The bottom end of the circular pipe 115 is connected to an exhaust pipe 116. The outlet end of the exhaust pipe 116 is inclined upward towards the bottom end of the flaw detector head 10. Several exhaust pipes 116 are provided and are evenly distributed along the axis of the circular pipe 115.

[0028] After the flaw detector head 10 finishes its inspection, the miniature air pump 111 starts and draws in gas. The drawn gas is then introduced into the first connecting pipe 112, the gas in the first connecting pipe 112 is introduced into the movable pipe 113, the gas in the movable pipe 113 is introduced into the second connecting pipe 114, and the gas in the second connecting pipe 114 is introduced into the annular pipe 115. The gas in the annular pipe 115 is dispersed and released from different exhaust pipes 116. The gas released from the exhaust pipes 116 cleans the bottom of the flaw detector head 10, separating debris from the flaw detector head 10 and preventing debris from affecting the inspection effect of the flaw detector head 10.

[0029] Example 3: When replacing the flaw detector head 10, the annular tube 115 is located outside the bottom end of the flaw detector head 10, making it inconvenient to replace the flaw detector head 10. (Refer to...) Figure 4As another preferred embodiment of this utility model, the difference from embodiment 2 is that the limiting member includes a connecting rod 117. One end of the connecting rod 117 is rotatably connected to the movable tube 113. An anti-slip sleeve is fitted on the connecting rod 117 to increase the friction between the hand and the connecting rod 117. The other end of the connecting rod 117 is fixedly connected to a card seat 118. The card seat 118 is engaged with the first connecting tube 112. A limiting ring 119 is fixedly connected to the first connecting tube 112. The bottom end of the card seat 118 is in contact with the upper end of the limiting ring 119.

[0030] When replacing the flaw detector head 10, the retaining ring 119 pulls the retaining seat 118. After the retaining seat 118 separates from the first connecting pipe 112, the movable pipe 113 is removed from the first connecting pipe 112, thereby removing the annular pipe 115. This does not obstruct the flaw detector head 10, thus facilitating the replacement of the flaw detector head 10.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
