Description

Technical Field

[0001] The utility model relates to the technical field of oil seal processing, in particular to an automatic trimming machine for oil seals. Background Art

[0002] Oil seals are mechanical components used to seal rotating shafts in mechanical equipment. Their main function is to prevent lubricating oil from leaking from transmission parts and to isolate pollutants in the external environment, such as water, chemical liquids, and dust. During the production process, there will be some excess material on the edge of the oil seal, which is usually called "burrs". Burrs not only affect the appearance quality of the product, but may also cause damage or functional impairment in subsequent use, so they need to be trimmed and cleaned.

[0003] Traditional deburring equipment mainly uses a manipulator to clamp the oil seal, and then the trimming knife rotates around the outer circumference of the oil seal to perform trimming. The manipulator will cause irregular deformation of the oil seal during the clamping process, resulting in reduced subsequent trimming accuracy. At the same time, the movement accuracy of the trimming knife rotating around the oil seal is difficult to ensure during long-term operation, and maintenance and calibration are difficult, which is not conducive to large-scale production.

[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to design an oil seal automatic trimming machine to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solution of the utility model and facilitating the understanding of those skilled in the art. It cannot be considered that the above contents are well known to those skilled in the art simply because they are explained in the background technology of the utility model. Utility Model Content

[0007] In order to achieve the above-mentioned purpose and other related purposes, the technical solution provided by the utility model is: an automatic trimming machine for oil seals, comprising a vibrating plate, a conveying mechanism and a trimming mechanism arranged in sequence, wherein:

[0008] The vibration plate is used to realize automatic conveying and sorting of oil seals, including a conveying slideway, a lever is provided on the side wall of the conveying slideway, and the distance between the lever and the bottom of the conveying slideway only allows a single oil seal to pass through, and the lever is used to prevent the oil seals from stacking together during the conveying process;

[0009] The conveying mechanism includes a conveyor belt, the front end of which is connected to the output port of the conveying slideway, and guide plates are provided on both sides of the conveyor belt to improve the conveying positioning accuracy of the oil seal; a baffle is provided at the rear end of the conveyor belt, and the baffle is used to cooperate with the guide plate to accurately position the oil seal; a transfer manipulator is provided on one side of the baffle, and a first contoured negative pressure suction cup is provided on the transfer manipulator, and a negative pressure suction port is added at the contact surface between the suction cup and the oil seal, and negative pressure adsorption is used instead of traditional clamps to improve the positioning accuracy and grasping efficiency of the transfer manipulator and the oil seal.

[0010] The trimming mechanism includes a workbench, on which is an oil seal turntable, which is connected to a driving device, and on which is a second contoured negative pressure suction cup, through which the oil seal is adsorbed and positioned, to avoid irregular deformation of the oil seal during the positioning process; a trimming knife mechanism and a feeding manipulator are respectively provided on both sides of the oil seal turntable, on which is a third contoured negative pressure suction cup, and a detection mechanism, a waste collection bin and a discharge chute are provided within the moving range of the feeding manipulator. It should be noted that the detection mechanism, the waste collection bin and the discharge chute are not limited to being arranged in sequence, but are arranged within the moving range of the feeding manipulator without interfering with each other; the trimming mechanism replaces the trimming knife mechanism with the rotation of the oil seal turntable, thereby increasing the stability of the trimming mechanism processing accuracy and reducing processing energy consumption.

[0011] The preferred technical solution is: there are two levers, and the two levers are arranged in sequence along the conveying slide, so that the arrangement of the sealing elements on the conveying slide is more neat.

[0012] The preferred technical solution is: a telescopic adjustment rod is provided at the rear end of the baffle to facilitate adjustment of the position of the baffle, so as to facilitate positioning of oil seals of different specifications.

[0013] The preferred technical solution is that the driving device is a servo motor.

[0014] The preferred technical solution is: the detection mechanism is a scanning camera, which is used to accurately detect whether the trimming of the oil seal is qualified.

[0015] The preferred technical solution is: the trimming knife mechanism includes a displacement component, and an encoder is provided at the displacement component for accurately controlling the moving distance of the trimming knife mechanism, thereby improving the trimming processing accuracy and being applicable to the trimming operations of oil seals of different specifications.

[0016] Due to the application of the above technical solution, the oil seal automatic trimming machine provided by the utility model has the following advantages over the prior art:

[0017] (1) An oil seal turntable with a negative pressure suction cup is used to control the oil seal to rotate and trim, replacing the traditional trimming knife rotating around the oil seal. This improves processing accuracy while reducing energy consumption and the difficulty of maintenance and correction;

[0018] (2) The oil seal is transferred and positioned by negative pressure adsorption, which improves the processing efficiency and avoids irregular deformation of the oil seal during transportation and processing. BRIEF DESCRIPTION OF THE DRAWINGS
