Description

Technical Field

[0001] The utility model relates to the technical field of crankshaft quenching, and more specifically, to a quenching device for crankshaft production. Background Art

[0002] Because it is necessary to improve the fatigue strength and the wear resistance of the journal surface of the crankshaft, induction heating quenching treatment is usually required for the crankshaft journal and fillet. During quenching, one end of the base shaft of the crankshaft is first movably fitted into the central hole of the fixture, and the eccentric journal is turned into the groove space of the inductor, so that the eccentric journal is in the two closed grooves and in a non-contact state. After the workpiece is in place, high-frequency induction heating is carried out by electrifying. After the high-temperature heating reaches the required temperature, the power is cut off and water is supplied. Cooling water sprays water on the eccentric journal through a number of through holes evenly distributed in the semi-circular groove to perform high-temperature quenching. After reaching the requirements, the water supply is stopped and the workpiece is unloaded. The crankshaft usually has multiple journals not on the same axis. When quenching such a crankshaft journal, usually after quenching one journal, the quenching position and fixture of the next journal need to be adjusted. During quenching, friction will occur on the surface of the workpiece to produce residues, and when there are more residues in the water tank, it is not only unfavorable for the quenching of the workpiece but also difficult to clean.

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 to 6 shown, the present invention provides a quenching device for crankshaft production, including an equipment main body 1. A filter plate 3 is inserted inside the equipment main body 1. An opening and closing door 2 is fixedly connected to the front end of the equipment main body 1. Bolts 17 are fixedly connected to the left and right ends of the opening and closing door 2. A sliding groove 5 is fixedly connected to the upper end of the equipment main body 1. A hole two 16 is opened on the side of the equipment main body 1. A plug 18 is inserted inside the hole two 16. A fixing plate 4 is fixedly installed on the upper end of the equipment main body 1. A sliding groove 5 is opened on the side of the fixing plate 4 close to the filter plate 3. A roller 6 is slidably connected inside the sliding groove 5. A cleaning roller 7 is sleeved on the surface of the roller 6. Fixing components 8 are clamped at the left and right ends of the roller 6. A push-pull column 13 is fixedly connected to the center of the lower end of the fixing component 8. A push-pull plate 10 is fixedly connected to the rear end of the push-pull column 13. A spring 11 is fixedly connected to the rear end of the push-pull plate 10. An air pressure box 9 is fixedly connected to the rear end of the spring 11. A ventilation pipe 12 is fixedly connected to the rear end of the air pressure box 9. An air pump 15 is fixedly connected to the lower end of the ventilation pipe 12. A hole one 14 is opened on the side of the air pressure box 9. A robotic arm 19 is provided on the upper end of the equipment main body 1. A crankshaft workpiece 20 is inserted between the robotic arms 19.

[0022] The air pump 15 is used to push the cleaning structure to automatically clean the residues attached to the cooled workpiece after quenching, which is beneficial to ensuring the cleanliness of the workpiece.

[0023] Among them, the filter plate 3 is inclined inside the equipment main body 1, and the end of the filter plate 3 close to the opening and closing door 2 is lower to form a slope.

[0024] It is beneficial to the convergence of residues and more beneficial to the efficient cleaning of residues.

[0025] Among them, a roller is movably connected to the upper end of the opening and closing door 2, and the roller is inserted on the front side of the equipment main body 1.

[0026] It is convenient to extract the filter plate 3 to clean the filtered residue.

[0027] Among them, the distance value of the first hole 14 from the front end of the air pressure box 9 is greater than the sum of the thickness values of the front end of the air pressure box 9 and the thickness value of the push-pull plate 10.

[0028] When the air pump 15 pushes the push-pull plate 10 to the top, the first hole 14 can ensure the stability of the internal air pressure.

[0029] Among them, there are two springs 11 at equal intervals inside the air pressure box 9, and the air pipe 12 is located at the center of the rear side of the air pressure box 9.

[0030] It can provide more sufficient pulling force to pull the push-pull plate 10 back to its original position, and the position of the air pipe 12 ensures that the force on the push-pull plate 10 is more uniform when it moves forward.

[0031] Among them, the length value of the push-pull column 13 is greater than the distance value between the cleaning roller 7 and the crankshaft workpiece 20.

[0032] Ensure that the push-pull column 13 can push the cleaning roller 7 to the position of the crankshaft workpiece 20 to clean the residue on the crankshaft workpiece 20.

[0033] The working principle and usage process of the present utility model:

[0034] When quenching the crankshaft is required, first fix the crankshaft to be quenched by the robotic arm 19, and then perform the quenching operation. The workpiece descends with the robotic arm 19 into the interior of the equipment main body 1 for cooling quenching. During the use of high-frequency quenching, certain residues will be generated, and the residues will immediately fall into the equipment main body 1 and be caught by the filter plate 3. After completion, the robotic arm 19 rises for cooling. At this time, the air pump 15 is started, and the air pump 15 passes gas through the air pipe 12 into the interior of the air pressure box 9. As the air pressure rises, the push-pull plate 10 moves forward to push the push-pull column 13 to drive the fixing component 8 to move together. The fixing component 8 pushes the roller 6 to move forward inside the sliding groove 5 until the cleaning roller 7 contacts the crankshaft workpiece 20. The robotic arm 19 drives the crankshaft workpiece 20 to rotate, and the crankshaft workpiece 20 and the cleaning roller 7 rub against each other to remove the residues attached to the surface. After the cleaning is completed, the air pump 15 is turned off, and the push-pull plate 10 is pulled back to its original position by the pulling force of the spring 11. When cleaning the residues in the pool, first pull out the plug 18 to drain the water inside, then remove the bolt 17, open the opening and closing door 2 to extract the filter plate 3 to complete the cleaning and replacement. After placing the new filter plate 3, fix the opening and closing door 2 through the bolt 17 to complete the cleaning.
