Description

Technical Field

[0001] The utility model relates to a rack leveling machine, belonging to the technical field of rack shape correction equipment. Background Art

[0002] The rack is a commonly used mechanical component. In some mechanical equipment, high precision requirements are placed on the rack, including high requirements for the straightness of the rack and the height tolerance of the tooth surface. The rack cannot be bent or arched on the sides, and the tooth surface height cannot vary too much. Therefore, the produced rack must be inspected and corrected accordingly to meet the requirements. However, some existing rack straightening and leveling devices are difficult to meet the requirements of simultaneous straightening and leveling of the rack, resulting in insufficient production continuity and relatively single functions.

[0003] Patent publication number CN 211679396 U discloses a rack straightening machine for calibrating rack straightness, comprising a workbench with a slide slidably mounted on the workbench, a vertically slidable straightening frame provided on the slide, an adjusting screw rotatably mounted on the slide, the adjusting screw being threadedly connected to the straightening frame, a horizontally sliding slider provided within the straightening frame, and a cylinder fixed to the straightening frame. The utility model utilizes the setting of the adjusting screw to rotate the adjusting screw to drive the straightening frame to slide when straightening racks of different thicknesses, so that when the slide slides to the bottom, the distance between the pressure wheel and the workbench is equal to the thickness of the rack, allowing the rack straightening machine to straighten racks of different thicknesses. The setting of the spring telescopic rod allows the pressure wheel to slide upward when the resistance is too great, avoiding the resistance of the rack and preventing the rack from being forced to break. However, this application does not address the problem of simultaneous straightening and leveling of the rack. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a rack leveling machine, which is used to straighten and level the rack so that the side flatness of the rack, the straightness of the rack and the height of the tooth surface meet the requirements, with good production continuity and high efficiency.

[0005] The camshaft is a gear that is adjusted relative to the gear of the driver, and the gear that is adjusted relative to the gear of the driver is moved along the gear wheel to move along the gear wheel shaft, so that the gear that is adjusted relative to the gear of the driver is moved along the gear wheel shaft.

[0006] Preferably, the plurality of first rack conveying rollers are arranged horizontally.

[0007] Preferably, a plurality of second rack conveying rollers are provided between the rack side leveling workbench and the rack shaping mechanism.

[0008] Preferably, the second rack conveying roller is parallel to the first rack conveying roller.

[0009] Preferably, the second rack conveying roller is parallel to the conveying chain.

[0010] Preferably, a ramp mechanism is provided on the sides of the two conveyor chains, the height of one end of the ramp mechanism is lower than the height of the other end, and the top surface of the other end of the ramp mechanism is an arc surface.

[0011] Preferably, a position sensor for sensing the height of the rack tooth surface is provided on the correction platform.

[0012] Preferably, the plurality of second rack conveying rollers are mounted on a frame, a pushing cylinder is provided on the frame, a push rod is provided at the outer end of the piston rod of the pushing cylinder, and the push rod is perpendicular to the conveying chain.

[0013] The beneficial effects of the utility model are as follows: the rack leveling machine of the utility model is used for straightening and leveling the rack, so that the side surface flatness of the rack, the straightness of the rack and the height of the tooth surface all meet the requirements, and the production continuity is good and the efficiency is high.

[0024] Preferably, a ramp mechanism 13 is provided beside the two conveyor chains 9. The ramp mechanism 13 is a plate-shaped body. One end of the ramp mechanism 13 is lower than the other end. The top surface of the other end of the ramp mechanism 13 is an arc surface.

[0025] Preferably, the correction platform 10 is provided with a position sensor for sensing the height of the rack tooth surface.

[0026] Preferably, the plurality of second rack conveying rollers 12 are mounted on a frame 14 , a pushing cylinder 15 is provided on the frame 14 , a push rod 16 is provided at the outer end of the piston rod of the pushing cylinder 15 , and the push rod 16 is perpendicular to the conveying chain.

[0027] When the rack leveling machine of the present invention is working, the manipulator 2 takes out the rack 17 from the rack material rack 1 and places it on multiple first rack conveying rollers 4. The two side surfaces of the rack 17 are horizontal. The rotating multiple first rack conveying rollers 4 move the rack 17 to between the upper and lower rack side leveling rollers 7 on the rack side leveling workbench 6. The spacing between the upper and lower rack side leveling rollers 7 is set in advance. After being rolled by the rack side leveling rollers 7, the two side surfaces of the rack 17 are leveled and straightened, and the arched parts are flattened. Then the rack 17 reaches the second rack conveying roller 12 and is conveyed to the push rod 16 by the second rack conveying roller 12. The piston rod of the pushing cylinder 15 extends to drive the push rod 16 to extend forward to push the rack 17 onto the two conveying chains 9. The two conveying chains 9 convey the rack 17 to the slope At the mechanism 13, the conveying chain 9 drives the rack 17 through one end of the ramp mechanism 13 to the arc surface of the other end of the ramp mechanism 13. The rack 17 falls from the arc surface of the other end of the ramp mechanism 13 and will flip 90° onto the conveying chain 9 and be blocked by the stopper 18, so that the rack 17 can only flip 90° onto the conveying chain 9. At this time, the tooth surface of the rack 17 is on the top, and the side of the rack 17 changes from horizontal to vertical. The stopper 18 is driven by the telescopic cylinder 19, and the piston rod of the telescopic cylinder 19 retracts so that the stopper 18 no longer blocks the rack 17. The conveying chain 9 continues to drive the rack 17 to the correction platform 10. The correction platform 10 is provided with a position sensor for sensing the height of the tooth surface of the rack 17. The hydraulic cylinder 11 drives the hydraulic head to move downward to press down and level the tooth surface of the rack 17, and shape the tooth surface of the rack 17 to meet the requirements.
