Description

Technical Field

[0001] The invention relates to the technical field of heat treatment of bearings, and in particular to a heat treatment device for robot bearings. Background Art

[0002] Robot bearings are widely used in the field of industrial robots, such as handling robots, welding robots, assembly robots, etc. Robot bearings need to be heat treated during the production and processing process. The main purpose is to transform the material structure through heat treatment and improve the mechanical properties of the material, thereby effectively improving the wear resistance and toughness of the bearings and extending the service life of the bearings. Robot bearings need to be placed on the tooling and then pushed into the heat treatment box during heat treatment. When the robot bearings are fixed by the tooling, the contact position between the bearings and the tooling is blocked, which affects the heating of this part of the bearing. In addition, during the heat treatment process, carbide impurities will be segregated on the bearings to block their surface, which also affects the heat treatment effect. Summary of the invention

[0003] The object of the present invention is to provide a heat treatment device for a robot bearing to overcome the above-mentioned defects in the prior art.

[0004] A heat treatment device for robot bearings includes a heat treatment box, a hanger and a sling assembly. The hanger is arranged in the heat treatment box. The sling assemblies are provided in a plurality and evenly distributed on the hanger. The sling assemblies are used to suspend the bearings and shake the bearings during heat treatment.

[0005] Preferably, the rack comprises a bottom plate, side plates and connecting plates, the side plates are symmetrically arranged on both sides of the bottom plate, and a plurality of connecting plates are evenly distributed from top to bottom between the side plates on both sides.

[0006] Preferably, the sling assembly includes a driving shaft, an impeller, a lifting cylinder, a hook and a driving block, the driving shaft is rotatably connected to the connecting plate and an impeller is provided at the upper end thereof, the lifting cylinder is sleeved on the driving shaft and sliding bars slidably connected to the connecting plate are provided on both sides thereof, the driving shaft is provided with an insertion rod inserted into the corrugated groove on the inner wall of the lifting cylinder, a plurality of fixed seats are evenly distributed along the circumference of the outer wall of the lifting cylinder, each fixed seat is rotatably connected to a hook via a rotating shaft, a torsion spring is sleeved on the rotating shaft, one end of the torsion spring is connected to the hook, and the other end of the torsion spring is connected to the fixed seat, the driving block is arranged at the lower end of the driving shaft and driving inclined surfaces are symmetrically provided on both sides thereof.

[0009] The beneficial effects achieved by the present invention are:

[0010] The present application performs heat treatment processing on the bearing through hot air from a heat treatment box. At the same time, the hot air will blow the impeller on the drive shaft and the drive shaft to rotate. The insertion rod on the drive shaft moves in the corrugated groove in the lifting cylinder, causing the lifting cylinder to move up and down, driving the bearing on the hook to move up and down. At the same time, the driving block on the drive shaft drives the hook to move back and forth through the driving inclined surface thereon, driving the bearing to vibrate. On the one hand, the bearing is constantly changing its position on the hook, so that the blocked position of the bearing can also be heat treated. On the other hand, the shaking of the bearing can drop the carbide produced by the heat treatment thereon, so that the bearing can be heat treated more effectively. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In addition, the sling assembly 3 includes a drive shaft 31, an impeller 32, a lifting cylinder 33, a hook 38 and a drive block 39. The drive shaft 31 is rotatably connected to the connecting plate 23 and an impeller 32 is provided at its upper end. The lifting cylinder 33 is sleeved on the drive shaft 31 and slide bars 34 slidably connected to the connecting plate 23 are provided on both sides thereof. The drive shaft 31 is provided with an insertion rod 35 inserted into the corrugated groove 331 on the inner wall of the lifting cylinder 33. A plurality of fixed seats 36 are evenly distributed along the circumference of the outer wall of the lifting cylinder 33. Each fixed seat 36 is rotatably connected to a hook 38 through a rotating shaft 37. A torsion spring 371 is sleeved on the rotating shaft 37. One end of the torsion spring 371 is connected to the hook 38, and the other end of the torsion spring 371 is connected to the fixed seat 36. The drive block 39 is provided at the lower end of the drive shaft 31 and driving inclined surfaces 391 are symmetrically provided on both sides thereof.

[0023] Specific implementation and principle:

[0024] S1, hang the bearing 4 to be heat treated on the hook 38 of the hanger assembly 3;

[0025] S2. After the bearings 4 are hung on the hooks 38, push the rack 2 into the heat treatment box 1 and close the door;

[0026] S3, the hot air in the heat treatment box 1 acts on the bearing 4 to perform a heat treatment operation on the bearing 4;

[0027] S4, the hot air in the heat treatment box 1 will simultaneously blow the impeller 32 on the drive shaft 31 to rotate, causing the drive shaft 31 to rotate, and the insertion rod 35 on the drive shaft 31 to move in the corrugated groove 331 in the lifting cylinder 33, causing the lifting cylinder 33 to move up and down, driving the bearing 4 on the hook 38 to move up and down, and at the same time, the driving block 39 on the drive shaft 31 drives the hook 38 to move forward and backward through the driving inclined surface 391 thereon, causing the bearing 4 to vibrate;

[0028] S5. After the heat treatment of the bearing 4 is completed, the door of the heat treatment box 1 is opened, the hanger 2 is pulled out of the heat treatment box 1 through the handle 25 on the hanger 2, and the bearing 4 is removed from the hook 38 on the hanger 2.

[0029] In summary, the present application performs heat treatment processing on the bearing 4 through the hot air of the heat treatment box 1. At the same time, the hot air will blow the impeller 32 on the drive shaft 31 and the drive shaft 31 to rotate. The insertion rod 35 on the drive shaft 31 moves in the corrugated groove 331 in the lifting cylinder 33, so that the lifting cylinder 33 moves up and down, driving the bearing 4 on the hook 38 to move up and down. At the same time, the driving block 39 on the drive shaft 31 drives the hook 38 to move back and forth through the driving inclined surface 391 thereon, driving the bearing 4 to vibrate. On the one hand, the bearing 4 is constantly changing its position on the hook 38, so that the blocked position of the bearing 4 can also be heat treated. On the other hand, the shaking of the bearing 4 can drop the carbide produced by the heat treatment thereon, so that the bearing 4 can be heat treated more effectively.
