Description

Technical Field

[0001] This utility model relates to the field of die-casting machine cup testing technology, and in particular to a thermal fatigue crack auxiliary testing device for die-casting machine cups. Background Technology

[0002] The die-casting cup is a crucial component in the die-casting production process. Under high temperature and high pressure working conditions, the cup is prone to thermal fatigue cracks. The presence of thermal fatigue cracks not only affects the service life of the cup but may also lead to quality problems in the die-cast products, such as porosity and shrinkage defects.

[0003] Currently, the detection of thermal fatigue cracks in die-casting machine cups mainly relies on manual visual inspection or handheld inspection instruments. Manual visual inspection is difficult to accurately detect tiny cracks, while handheld inspection instruments improve the accuracy of detection to some extent. However, during the inspection process, the operator's hand tremors make it difficult to ensure that the detection head maintains stable contact and appropriate pressure with the surface of the cup. This leads to unstable detection signals, affecting the accuracy of the detection results. Furthermore, prolonged handheld inspection can easily cause operator fatigue.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A thermal fatigue crack auxiliary detection device for die casting machine cups includes a base 1, a detection component 2 is provided on the right side of the top of the base 1, and a rotation fixing component 3 is provided on the left side of the top of the base 1.

[0027] The detection assembly 2 includes a first electric telescopic rod 201 and an ultrasonic flaw detector 202. The first electric telescopic rod 201 is fixedly connected to the right side of the top of the base 1, and the ultrasonic flaw detector 202 is fixedly connected to the front side of the top of the base 1. The output rod of the first electric telescopic rod 201 is fixedly connected to an L-shaped plate 203. The top of the L-shaped plate 203 is fixedly connected to a second electric telescopic rod 204. The output rod of the second electric telescopic rod 204 passes through the L-shaped plate 203 and is fixedly connected to a fixing plate 205. A fixing block 206 is provided on the left side of the fixing plate 205. Springs 207 are fixedly connected to the front and rear sides of the fixing plate 205 and the fixing block 206. A flaw detector head 208 is fixedly connected to the inner side of the fixing block 206. The flaw detector head 208 is electrically connected to the ultrasonic flaw detector 202.

[0028] In this embodiment: by setting a base 1, a detection component 2, and a rotation fixing component 3, the base 1 can support and fix the detection component 2 and the rotation fixing component 3 during use. The detection component 2 can perform thermal fatigue crack detection on the die-casting machine cup, and the detection height position can be easily adjusted. Compared with manual handheld detection, it can effectively improve the stability and detection accuracy during the detection process. The rotation fixing component 3 can support and fix the die-casting machine cup to be detected, so that the die-casting machine cup will not shake or shift during the detection process. It can also easily drive the die-casting machine cup to rotate at multiple angles, so that the detection component 2 can detect different areas of the cup without frequent and large-scale position adjustments, thereby improving detection efficiency.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 5As shown, the rotating fixing assembly 3 includes a rotating motor 301, which is fixedly connected to the left side of the top of the base 1. The output shaft of the rotating motor 301 is fixedly connected to a transmission frame 302, and the top of the transmission frame 302 is fixedly connected to a support platform 303.

[0030] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, a throttle 304 is provided on the front side of the support platform 303, and a bidirectional screw 305 is fixedly connected to the rear side of the throttle 304. The rear side of the bidirectional screw 305 extends to the rear side of the support platform 303. The side of the surface of the bidirectional screw 305 near the inner wall of the support platform 303 is rotatably connected to the inner wall of the support platform 303 through a bearing. Both the front and rear sides of the surface of the bidirectional screw 305 are threaded with internal thread blocks 306. An arc-shaped clamping block 307 is fixedly connected to the top of each of the two internal thread blocks 306. A rubber pad 308 is fixedly connected to the inner side of the arc-shaped clamping block 307.

[0031] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, the top of the support platform 303 is provided with a limiting groove 309 that works in conjunction with the internal thread block 306, and the two sides of the internal thread block 306 are slidably connected to the two sides of the inner wall of the limiting groove 309.

[0032] In this embodiment: by setting up a rotating motor 301, a transmission frame 302, a support platform 303, a throttle 304, a bidirectional screw 305, internal threaded blocks 306, arc-shaped clamping blocks 307, a rubber pad 308, and a limiting groove 309, in use, the die-casting machine cup is placed on top of the support platform 303, and then the throttle 304 can be rotated, causing the bidirectional screw 305 to rotate. The rotation of the bidirectional screw 305 causes the two internal threaded blocks 306 to move simultaneously in opposite directions within the limiting groove 309 via the threads. The two internal threaded blocks 306 will then respectively drive the two arc-shaped clamping blocks 307 to move in opposite directions, causing the two arc-shaped clamping blocks 308 to move in opposite directions. 7. The rubber pad 308 can be tightly fitted to the die-casting machine cup, thereby clamping and fixing the die-casting machine cup, preventing it from shaking or shifting during the inspection process. The rubber pad 308 can prevent damage to the surface of the cup during the fixing process, while increasing friction. Furthermore, by starting the rotating motor 301, the output shaft of the rotating motor 301 drives the transmission frame 302 to rotate, which in turn drives the support platform 303 to rotate. This allows the die-casting machine cup to rotate at multiple angles, enabling the inspection component 2 to inspect different areas of the cup without frequent and significant position adjustments, thus improving inspection efficiency.

[0033] Specifically, such as Figure 3As shown, the left side of the L-shaped plate 203 is provided with a through hole 4 for use with the second electric telescopic rod 204, and the output rod of the second electric telescopic rod 204 is slidably connected to the inner wall of the through hole 4.

[0034] Specifically, such as Figure 1 , Figure 3 As shown, the inner cavity of the spring 207 is provided with a limiting rod 5. The left side of the limiting rod 5 is fixedly connected to the right side of the fixing block 206. The right side of the limiting rod 5 extends through to the right side of the fixing plate 205. The front and rear sides of the left side of the fixing plate 205 are provided with sliding holes 6 that cooperate with the limiting rod 5. The surface of the limiting rod 5 is slidably connected to the inner wall of the sliding hole 6.

[0035] In this embodiment: by providing a through hole 4, the output rod of the second electric telescopic rod 204 can pass through the L-shaped plate 203 for telescopic output; by providing a limiting rod 5, the fixed block 206 can be limited to prevent the fixed block 206 from shaking; by providing a sliding hole 6, the limiting rod 5 can move left and right with the fixed block 206.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, a controller 7 is provided on the right side of the front top of the base 1, which works in conjunction with the first electric telescopic rod 201, the second electric telescopic rod 204 and the rotating motor 301. A fixing strip 8 is fixedly connected to the bottom of the controller 7, and the bottom of the fixing strip 8 is fixedly connected to the base 1.

[0037] Specifically, such as Figure 1 , Figure 2 As shown, an anti-slip pad 9 is fixedly connected to the bottom of the base 1, and the bottom of the anti-slip pad 9 is provided with anti-slip texture.

[0038] In this embodiment: by setting the controller 7, the first electric telescopic rod 201, the second electric telescopic rod 204 and the rotating motor 301 can be easily operated. By setting the fixing strip 8, the controller 7 can be supported and fixed. By setting the anti-slip pad 9, the anti-slip performance of the base 1 can be improved, so that the base 1 can maintain stability during the testing process.

[0039] Working principle: During use, the die-casting machine cup can be placed on top of the support platform 303. Then, the throttle 304 can be rotated, causing the double-acting screw 305 to rotate. The rotation of the double-acting screw 305 causes two internally threaded blocks 306 to move simultaneously in opposite directions within the limiting groove 309. The two internally threaded blocks 306 will then drive two arc-shaped clamping blocks 307 to move in opposite directions, allowing the two arc-shaped clamping blocks 307 to fit tightly against the die-casting machine cup via the rubber pad 308, thus enabling proper die casting. The material cup is clamped and fixed. Then, the controller 7 controls the first electric telescopic rod 201 to work, causing the output rod of the first electric telescopic rod 201 to move the L-shaped plate 203 up and down, thereby adjusting the detection height position of the flaw detector 208. After that, the controller 7 controls the second electric telescopic rod 204 to work, causing the output rod of the second electric telescopic rod 204 to move the fixing plate 205 and the flaw detector 208, bringing the flaw detector 208 close to the surface of the material cup. When the flaw detector 208 approaches the surface of the material cup, the flaw detector 208 and the fixing plate 205... Spring 207 between 05 and 05 will undergo compression or tension deformation, while the limiting rod 5 slides within the sliding hole 6 of the fixed plate 205, playing a limiting and guiding role, ensuring that the flaw detector 208 can adaptively and tightly fit the surface of the cup. This elastic connection method ensures a good coupling effect between the flaw detector 208 and the surface of the cup, which is conducive to the effective propagation of ultrasonic waves. After the flaw detector 208 is in contact with the surface of the cup, the ultrasonic flaw detector 202 is activated, and the flaw detector 208 emits ultrasonic waves into the cup. When the ultrasonic waves propagate in the cup and encounter defects such as thermal fatigue cracks... When the light is reflected, the reflected wave is received by the flaw detector head 208 and converted into an electrical signal, which is then transmitted to the ultrasonic flaw detector 202. This enables the detection of thermal fatigue cracks in the material cup. Furthermore, the controller 7 can control the operation of the rotating motor 301, causing the output shaft of the rotating motor 301 to drive the transmission frame 302 to rotate. The transmission frame 302 will then drive the support platform 303 to rotate, thereby enabling the material cup to rotate at multiple angles. This allows the flaw detector head 208 to detect different areas of the material cup without frequent and significant position adjustments, thus improving detection efficiency.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
