Description

Technical Field

[0001] The utility model relates to a feeding device for a rear crankshaft oil seal, in particular to a feeding device for air tightness detection of a rear crankshaft oil seal. Background Art

[0002] The back of the rear crankshaft oil seal has two protruding positioning pins. During the air tightness detection of the rear crankshaft oil seal, it is necessary to place the rear crankshaft oil seal on the conveyor belt for transportation. However, due to the interference of the positioning pins, the rear crankshaft oil seal is often placed on the conveyor belt in an inclined state and is not easily grabbed by the horizontally arranged suction cup at the end of the conveyor line. Moreover, when the existing rear crankshaft oil seals are transported on the conveyor belt, they will shift to a certain extent and cannot be accurately grabbed by the suction cup.

[0003] In summary, how to achieve the horizontal transportation of the rear crankshaft oil seal on the conveyor belt to facilitate the accurate grabbing by the suction cup has become an urgent problem for researchers in this field. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: how to achieve the horizontal transportation of the rear crankshaft oil seal on the conveyor belt;

[0005] To solve the above technical problem, the technical solution adopted by the utility model is:

[0006] The utility model is a feeding device for air tightness detection of a rear crankshaft oil seal, including: a frame; a driving shaft rotatably arranged on one side of the frame; a driven shaft rotatably arranged on the other side of the frame; a first conveyor belt rotatably arranged between the driving shaft and the driven shaft; a second conveyor belt rotatably arranged between the driving shaft and the driven shaft, and a gap for placing the positioning pins of the rear crankshaft oil seal is formed between the second conveyor belt and the first conveyor belt;

[0007] Compared with the traditional method of using a single conveyor belt, in this solution, both the first conveyor belt and the second conveyor belt are wound around the driving shaft and the driven shaft. When the driving shaft rotates, it drives the first conveyor belt and the second conveyor belt to rotate synchronously. There is a gap between the first conveyor belt and the second conveyor belt, and the gap is used to place the positioning pins. In this way, the lower surface of the rear crankshaft oil seal is supported by the first conveyor belt and the second conveyor belt respectively, so that the rear crankshaft oil seal can be in a horizontal state during transportation, which is convenient for subsequent adsorption by the suction cup;

[0008] In addition, since the two positioning pins of the rear crankshaft oil seal are located in the gap, and the positioning pins are matched with the gap, it can prevent the rear crankshaft oil seal from shifting during transportation and can play a role in positioning the rear crankshaft oil seal during transportation.

[0009] To prevent the first conveyor belt and the second conveyor belt from axially moving on the driving shaft and the driven shaft, resulting in a change in the gap distance and affecting the placement and transportation of the rear crankshaft oil seal, the present utility model is characterized in that first limit rings and second limit rings are respectively arranged at both ends of the driving shaft and the driven shaft; a third limit ring is arranged in the middle of the driving shaft and the driven shaft; wherein, the distance between the first limit ring and the third limit ring matches the bandwidth of the first conveyor belt; the distance between the second limit ring and the third limit ring matches the bandwidth of the second conveyor belt;

[0010] The end of the first conveyor belt is limited between the first limit ring and the third limit ring, and the end of the second conveyor belt is limited between the second limit ring and the third limit ring. In this way, the distance between the first conveyor belt and the second conveyor belt will not change, ensuring the stability of transporting the rear crankshaft oil seal.

[0011] In order to support the rear crankshaft oil seal during transportation and prevent the first conveyor belt and the second conveyor belt from undergoing excessive deformation and resulting in bending and fracture, the present utility model is characterized in that a support cover plate is installed on the top of the frame; the cover plate is located below the conveying surfaces of the first conveyor belt and the second conveyor belt; a groove matching the gap is opened along the length direction of the support cover plate;

[0012] In this solution, the support cover plate is fixed to the frame. During the transportation of the rear crankshaft oil seal, the first conveyor belt and the second conveyor belt come into contact with the support cover plate, preventing the first conveyor belt and the second conveyor belt from bending and resulting in fracture. The support cover plate plays a role in supporting the rear crankshaft oil seal;

[0013] The groove is opened along the length direction of the support cover plate and is located below the gap. The purpose of opening the groove is to prevent interference with the positioning pin.

[0014] To illustrate how the driving shaft rotates, the present utility model is characterized in that the rotation of the driving shaft is controlled by a motor.

[0015] The beneficial effects of the present utility model: The present utility model is a feeding device for airtightness detection of the rear crankshaft oil seal. There is a gap between the first conveyor belt and the second conveyor belt, and a positioning pin is placed at the gap. In this way, the lower surface of the rear crankshaft oil seal is respectively supported by the first conveyor belt and the second conveyor belt, enabling the rear crankshaft oil seal to be in a horizontal state during transportation, which is convenient for subsequent adsorption by the suction cup; since the two positioning pins of the rear crankshaft oil seal are located in the gap and the positioning pin is matched with the gap, it can prevent the rear crankshaft oil seal from shifting during transportation and can play a role in positioning the rear crankshaft oil seal during transportation.

[0023] Compared with the traditional one-conveyor-belt method, in this solution, both the first conveyor belt and the second conveyor belt are wound around the driving shaft and the driven shaft.

[0026] The end of the first conveyor belt is limited between the first limiting ring and the third limiting ring, and the end of the second conveyor belt is limited between the second limiting ring and the third limiting ring. In this way, the distance between the first conveyor belt and the second conveyor belt will not change, ensuring the stability of transporting the rear crankshaft oil seal.
