Description

Technical Field

[0001] This utility model relates to the field of crankshaft testing technology, specifically to a high-efficiency crankshaft magnetic particle flaw detector. Background Technology

[0002] The crankshaft is the most important component in the engine. It bears the force transmitted from the connecting rod and converts it into torque, which is output through the crankshaft to drive other accessories on the engine. After production, the crankshaft will be inspected by spraying magnetic suspension liquid with a magnetic particle inspection machine to detect defects on the outer end face of the crankshaft.

[0003] Existing crankshaft magnetic particle testing machines, such as the one disclosed in publication number CN213749726U for testing the crankshaft of a compressor, have the advantage of using a stirring paddle to mix fluorescent magnetic powder and water in the storage tank in a certain proportion, thereby using machinery to replace manual production of magnetic suspension. However, this crankshaft magnetic particle testing machine has the inconvenience of setting a rotating station at the inner end, which makes it inconvenient to alternately spray and test the crankshaft inside the testing machine, thus reducing the testing efficiency. Therefore, we propose a high-efficiency crankshaft magnetic particle testing machine. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Preferably, the first pressing plate and the second pressing plate have the same structure.

[0007] Preferably, mounting holes are arranged on all four sides of the first and second clamping plates, and movable columns are movably installed in each mounting hole.

[0008] Preferably, fixing rods are also fixedly installed on all four sides of the first and second pressing plates, and the fixing rods are all located on one side of the mounting holes.

[0010] Preferably, a second geared motor is also fixedly installed at the center of the top of the chassis, and the front end of the second geared motor is fixedly connected to the fixed shaft.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In this utility model, the first clamping plate and the second clamping plate installed at both ends of the rotating disk inside the chassis can press the crankshaft installed between them. The crankshaft can be rotated and adjusted at both ends inside the chassis to alternately spray the magnetic suspension liquid through the spray pipe and the detector and then perform the detection after spraying. Thus, the detection efficiency of this magnetic particle flaw detector is improved through the alternating operation. 2. In this utility model, the movable columns installed on the four sides of the first and second pressing plates can also bind the crankshaft on the outside during pressing, so as to ensure its stability during rotation adjustment.

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0015] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a high-efficiency crankshaft magnetic particle flaw detector.

An electric push rod 208 is fixedly installed on the right fixed bracket 205. A bearing 209 is fixedly installed at the front end of the electric push rod 208. A fixed seat 210 is fixedly installed at the outer end of the bearing 209. A second pressing plate 211 is fixedly installed at the front end of the fixed seat 210. The first pressing plate 207 and the second pressing plate 211 have the same structure. Mounting holes 212 are arranged on the four sides of the first pressing plate 207 and the second pressing plate 211. Movable columns 213 are movably installed in the mounting holes 212. Fixed rods 214 are also arranged and fixedly installed on the four sides of the first pressing plate 207 and the second pressing plate 211. The fixed rods 214 are all located on one side of the mounting holes 212. Springs 215 are movably installed at the outer end of the fixed rods 214. A second reduction motor 216 is fixedly installed at the center of the top of the housing 101. The front end of the second reduction motor 216 is fixedly connected to the fixed shaft 202.

[0017] Specifically, the crankshaft is the most important component in the engine. After production, the crankshaft undergoes flaw detection by a magnetic particle inspection machine spraying magnetic suspension fluid to detect defects on its outer end face. The first clamping plate 207 and the second clamping plate 211 installed at both ends of the rotating disk 201 inside the housing 101 allow the crankshaft, which is clamped between them, to rotate and adjust within the housing 101, alternating between spraying the magnetic suspension fluid through the spray pipe 102 and the detector 103, and then performing subsequent inspections. This alternating operation improves the detection efficiency of the magnetic particle inspection machine. Simultaneously, the movable columns 213 installed on the four sides of the first clamping plate 207 and the second clamping plate 211 can also externally restrain the crankshaft during clamping, ensuring stability during rotation. The movable columns 213, which allow for retraction adjustment, also enable the first and second clamping plates 207 and 211 to protect crankshafts of different sizes after clamping, improving their applicability. The fixed shaft 20 at the center of the rotating disk 201... 2. Its top is fixedly connected to the second reduction motor 216 for overall speed reduction and rotation adjustment of the rotating disk 201. The partitions 203 at both ends of the rotating disk 201 are mainly used for separation on both sides for spraying and inspection work respectively. The first reduction motor 206 installed on the left fixed frame 204 is mainly used for the rotation adjustment of the crankshaft pressed on the first pressure plate 207 on its outer side. The electric push rod 208 on the right fixed frame 205 is mainly used for the pressure adjustment of the second pressure plate 211 to press the crankshaft between the second pressure plate 211 and the first pressure plate 207. The bearing 209 installed between the front end of the electric push rod 208 and the fixed seat 210 is mainly for facilitating the rotation adjustment of the second pressure plate 211. The spring 215 installed on the outer end of the inner fixed rod 214 of the first pressure plate 207 and the second pressure plate 211 is mainly for facilitating the contraction adjustment of the outer movable column 213 during compression. The fixed rod 214 at the outer end of the spring 215 is mainly for ensuring the stability during compression adjustment.

[0018] Working principle and usage process of this utility model: After the crankshafts, which are clamped and installed at both ends on the rotating disk 201 inside the housing 101, have completed spraying and testing, the second reduction motor 216 at the top can be started to rotate the rotating disk 201 180 degrees. This rotates the crankshaft sprayed on one side to the lower end of the detector 103 for testing, and rotates the crankshaft tested on one side to the lower end of the spray pipe 102. After the rotating disk 201 has been rotated and adjusted, the electric push rod 208 can be started to move back, thereby removing the tested crankshaft between the first clamping plate 207 and the second clamping plate 211, and then... A new crankshaft is installed between the first clamping plate 207 and the second clamping plate 211. The electric push rod 208 is restarted to press the new crankshaft between the first clamping plate 207 and the second clamping plate 211. Then, the first reduction motor 206 is started to rotate the new crankshaft between the first clamping plate 207 and the second clamping plate 211. After rotation, the crankshaft is sprayed through the upper spray pipe 102. After the crankshaft is inspected at the other end of the rotating plate 201, the crankshaft is rotated alternately to improve the efficiency of the crankshaft inspection by the main body 100 of the flaw detector.
