Description

Technical Field

[0001] The present invention belongs to the technical field of flaw detection equipment, and particularly relates to an integrated machine for crankshaft fluorescent magnetic particle flaw detection and drying. Background Art

[0002] The crankshaft is the most important component in an engine. The crankshaft is subjected to the combined action of the centrifugal force of the rotating mass, the periodic gas inertia force, and the reciprocating inertia force, causing the crankshaft to bear the action of bending and torsional loads. Therefore, it is required that the crankshaft has sufficient strength and stiffness, and its quality directly affects the safety of the engine operation. Therefore, before the crankshaft is put into use, quality inspections such as flaw detection and compressive strength need to be carried out to ensure that the crankshaft put into use can have a high service life.

[0003] The existing crankshaft magnetic particle flaw detectors have the following defects: 1. The existing flaw detectors cannot be compatible with multiple models of crankshafts for flaw detection operations; 2. During the detection process of the existing crankshaft flaw detection, it is easy to deviate, affecting the detection effect; 3. In the existing flaw detection observation station, it is observed by hand-held by workers or rotated by lifting with a rod. This observation and inspection method will cause magnetic marks on the workpiece to be worn, resulting in missed inspections. At the same time, due to the cumbersome operation, it increases the labor intensity of workers and will also cause magnetic suspension droplets to leak, making the machine tool and the surrounding area of the machine tool unclean; 4. After the crankshaft flaw detection is completed, demagnetization is required, and then workers need to spray an anti-rust agent on its surface and further dry it, with a large labor intensity and low work efficiency. Those skilled in the art urgently need to solve such technical problems. Summary of the Invention

[0048] Based on the above embodiments, as Figures 11-12 shown, the adjustable observation seat 302 is provided with a first adjustment component 3021. The first adjustment component 3021 is installed on the first mounting plate 3024. A support plate 3022 is installed on the first adjustment component 3021. Two support plates 3022 are symmetrically arranged. At the front ends of the two support plates 3022, rollers 3023 for lifting the workpiece are installed. An operator manually observes the surface quality of the workpiece by the auxiliary rotation of the rollers 3023.

[0049] Based on the above embodiments, as Figure 13 shown, the first blanking device 303 is arranged between the two groups of rollers 3023.

The bottom of the slope panel 3031 is connected with a first air cylinder 3032 capable of driving the slope panel 3031 to lift and lower. The lower side of the slope panel 3031 faces outward. The first air cylinder 3032 lifts the slope panel 3031 to connect the workpieces on the two groups of rollers 3023, and the workpieces roll down along the slope to the defective product box. When the observation of the workpiece is completed and it rotates to the defective product station, if it is a defective product, the first blanking device 303 is started. The first air cylinder 3032 drives the slope panel 3031 to rise, connects the workpiece and rolls it down along the slope of the slope panel 3031 to the defective product blanking box.

[0050] Based on the above embodiments, as Figure 14As shown, the second blanking device 304 is arranged between two groups of rollers 3023. The second blanking device 304 is provided with a blanking ramp plate 3041. Two blanking ramp plates 3041 are arranged in parallel and are connected through a second adjusting component 3042. The lower end of the second adjusting component 3042 is connected to a second mounting plate 3043. The lower end of the second mounting plate 3043 is connected to a second cylinder 3044. The lower end of the blanking ramp plate 3041 faces outward and is provided with a material blocking block to prevent the workpiece from slipping. If it is a qualified product, it rotates to the qualified product station, and the second blanking device 304 is started. The second cylinder 3044 drives the second adjusting component 3042 to move upward, connects the workpiece smoothly through the blanking ramp plate 3041, and rolls to one end of the material blocking block of the blanking ramp plate 3041. At the same time, the second cylinder 3044 moves downward, and then the clamping device of the next process clamps and conveys the workpiece.

[0051] On the basis of the above embodiments, as Figure 8 shown, the loading mechanism 2 is set as a chain drive, including a loading support base 201 and a loading chain 202. A number of loading support bases 201 are installed on the loading chain 202. Loading sprockets 203 are installed at both ends of the loading chain 202. The loading sprockets 203 are installed on a movable bracket 204, which is convenient for adjusting the distance between the loading sprockets 203, that is, adjusting the distance between the loading support bases 201 to meet the installation and transportation of crankshafts of various models. The two movable brackets 204 on both sides are installed on the pitch adjustment lead screw 205, and a handwheel 206 is installed at one end of the pitch adjustment lead screw 205.

[0052] On the basis of the above embodiments, as Figure 9 shown, the loading and unloading trolley 6 includes a support guide rail 601, a walking cylinder 602, and a lifting cylinder 603. The support guide rail 601 is installed on the frame 1. A sliding plate 605 is installed on the support guide rail 601. One end of the sliding plate 605 is connected to the walking cylinder 602. The walking cylinder 602 is fixed on the loading mechanism 2. The movable end of the lifting cylinder 603 passes through the sliding plate 602 and is connected to a trolley support seat 604.

The electrode head 701 is connected to the electrode main shaft 702. One end of the electrode main shaft 702 away from the electrode head 701 is connected to the electrode cylinder 703. A fixed coil 704 is sleeved on one end of the electrode main shaft 702 close to the electrode head 701. The electrode cylinder 703 pushes the electrode main shaft 702 to drive the electrode head 701 to relatively clamp the crankshaft for flaw detection operations. A lead screw nut seat is installed at the lower end of the electrode clamping device 7, which can conveniently adjust the position of the electrode clamping device 7 to adapt to the flaw detection clamping of crankshafts of various models.

[0054] On the basis of the above embodiment, in order to reduce the overall size of the rotary observation mechanism, the support plate 3022 is set as a Z-shaped structure. The two support plates 3022 are large-end open at the end close to the roller 3023, and the small-end openings are connected to the first adjustment component 3021. Without shortening the distance between the two groups of rollers 3023, by reducing the distance at one end of the support plate 3022 and simultaneously reducing the first adjustment component 3021, the turntable 301 is further reduced, achieving the purpose of reducing the overall size of the rotary observation mechanism. The first adjustment component 3021 includes a lead screw, a nut, a guide rod, and a handwheel. The nuts are relatively fixed on the two support plates 3022. The lead screw passes through the nut and is installed on a bearing seat. One end of the lead screw is connected to a handwheel. Guide rods are arranged in parallel on both sides of the lead screw. The second adjustment component 3042 is arranged in the same way as the first adjustment component 3021.

[0056] On the basis of the above embodiment, as Figure 16 shown, the conveyor line 11 is a chain conveyor line. A blanking support seat 1101 is installed on the chain conveyor line. The distance between the two blanking support seats 1101 is adjustable to meet the installation and transportation of crankshafts of various models.

[0057] Working principle:

[0058] The crankshaft fluorescence magnetic particle flaw detection and drying integrated machine of the present invention is a crankshaft flaw detection machine device, which is integrated with a drying line and is arranged in an overall L shape, saving space;

[0059] The crankshaft is transported step by step to the flaw detection machine loading station through the loading support seat 201 on the loading chain 202. The position of the loading support seat 201 can be adjusted by the handwheel 206 on one side to be compatible with the flaw detection loading of various crankshafts;

[0060] The positioning grooves at the front end of the loading and unloading trolley 6 of the crankshaft are used to transfer the crankshaft at the loading mechanism 2 to the electrode clamping device, and the positioning grooves at the rear end are used to transfer the magnetized crankshaft to the rotary observation mechanism 3, which increases the flaw detection efficiency to a certain extent; on both sides of the electrode clamping device 7, the position of the electrode head 701 is adjusted by a handwheel driving a lead screw, which can meet the flaw detection requirements of crankshafts of various sizes; the coil lifting device 8 lowers the coil 802 during flaw detection and raises it after flaw detection is completed, without affecting the loading and unloading of the crankshaft.

[0061] After flaw detection is completed, the crankshaft is conveyed by the loading and unloading trolley 6 to the adjustable observation seat 302 of the rotary observation mechanism 3. The rotary observation mechanism 3 drives the turntable 301 to rotate through a speed reducer, so that the crankshaft is conveyed to the observation position, and the qualified products are rotated to the qualified product unloading station.

[0062] By rotating the servo motor of the driving assembly 402, the grasping manipulator 403 is moved to the qualified product unloading station. The grasping manipulator 403 is arranged to be liftable. By lowering the grasping manipulator 403 to a suitable position, and then clamping the crankshaft by the clamping cylinder, the crankshaft is placed into the liquid tank 404 filled with rust inhibitor. Then, by rotating the servo motor of the driving assembly 402, the grasping manipulator 403 is moved to the demagnetization and drying mechanism for drying treatment.

[0063] The crankshaft is placed on the conveying line 11. First, the residual magnetic quantity on the crankshaft is removed by the demagnetization coil 501, and then the rust inhibitor on the crankshaft is dried by the blowing and drying device installed above the conveying line 11. After drying is completed, the crankshaft is taken down from the unloading end for boxing.

The use of front, rear, left and right in the text is not specifically referred to, mainly for more intuitively explaining the technical solution and does not play a limiting role. Those skilled in the art should understand that the above embodiments are only for explaining the technical concept and features of the present invention, and the purpose is to enable those familiar with this technology to understand the content of the present invention and implement it, and cannot be used to limit the protection scope of the present invention.
