Description

Technical Field

[0001] The utility model relates to the technical field of automobile pulley processing, in particular to a drilling device for automobile pulley processing. Background Technique

[0002] The pulley plays an important role in the transmission of an automobile. The pulley belongs to the disc hub parts, generally with relatively large dimensions. In the manufacturing process, it is mainly casting and forging, and is mainly used in the occasion of transmitting power over a long distance. The engine belt is generally divided into the engine timing belt and the crankshaft belt. The timing belt is the belt connecting the crankshaft and the camshaft, and the crankshaft drives the camshaft to rotate through the belt.

[0003] Usually, after the automobile pulley is drilled, there will be iron chips remaining in the hole. When performing subsequent process treatment, it is necessary to manually clean the iron chips in the hole with an air gun, which is rather inconvenient and delays the subsequent process treatment. Therefore, we propose a drilling device for automobile pulley processing to solve the problems mentioned above. Content of the Utility Model

[0004] The purpose of the utility model is to provide a drilling device for automobile pulley processing to solve the problem that usually, after the automobile pulley is drilled, there will be iron chips remaining in the hole, and when performing subsequent process treatment, it is necessary to manually clean the iron chips in the hole with an air gun, which is rather inconvenient and delays the subsequent process treatment as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A drilling device for automobile pulley processing, including a processing table and a top plate, and the top plate is located above the processing table;

[0006] It further includes:

[0007] A cylinder, which is arranged on the top of the top plate. A telescopic rod is arranged at the bottom of the top plate, and the telescopic rod is driven by the cylinder to move up and down. A second motor is arranged at the bottom of the telescopic rod, and a drill bit is installed at the bottom of the second motor. The outer movable part of the telescopic rod is provided with a protective cover, and the inner bottom end of the protective cover is open. Fixing frames are symmetrically arranged at the upper end inside the protective cover. A semi-circular ring plate is arranged between the two fixing frames. The semi-circular ring plate is located on one side of the second motor. The semi-circular ring plate is installed between the two fixing frames through a rotating shaft. A first motor is arranged outside the left fixing frame, and the first motor drives the rotating shaft to drive the semi-circular ring plate to swing between the two fixing frames. A cleaning pipe is arranged in the middle of the outside of the semi-circular ring plate, and the upper and lower ends inside the cleaning pipe are open. A clamp is arranged on the upper end of the processing table.

[0008] Preferably, a pressing plate is provided at the upper end of the outer part of the telescopic rod, and a limiting plate is provided at the lower end of the outer part of the telescopic rod. The limiting plate is movably attached to the upper end inside the protective cover. A spring is provided below the pressing plate, and the bottom of the spring is attached to the upper surface of the protective cover.

[0009] Preferably, nylon brushes are evenly distributed on the outer surface of the cleaning pipe.

[0010] Preferably, an air pipe extends into the protective cover, and the air pipe is connected to the inside of the cleaning pipe.

[0011] Preferably, the air pipe is fixed to the surfaces of the fixing frame and the semi-circular ring plate by a buckle.

[0012] Preferably, a rubber pad is provided at the bottom of the protective cover.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By providing a protective cover on the outer part of the telescopic rod and arranging the second motor and the drill bit inside the protective cover, the protective cover can prevent iron filings from splashing when the drill bit drills. A spring and a pressing plate are provided at the upper end of the protective cover. When the protective cover moves downward, it can first contact the processing table, and then the telescopic rod can move downward further to lower the drill bit for drilling. When the drill bit rises after drilling, the protective cover is attached to the processing table through the spring and the pressing plate. Until the drill bit completely rises, the protective cover is lifted upward by the limiting plate, which can prevent the protective cover from rising together or preferentially when the drill bit rises. The drill bit rising prior to the protective cover can ensure that the protective cover can fully play a protective role.

[0015] 2. By providing a fixing frame inside the protective cover and a semi-circular ring plate between the fixing frames, the annular structure of the semi-circular ring plate can completely avoid the second motor and the drill bit. When drilling is required, first drive the semi-circular ring plate to be in a state horizontal to the processing table. After drilling is completed, the drill bit can be lifted upward, and at the same time, the semi-circular ring plate is rotated so that the semi-circular ring plate is in a position perpendicular to the processing table, enabling the cleaning pipe to be located above the drill hole. Then, drive the telescopic rod to descend again, so that the cleaning pipe extends into the drill hole. At the same time, high-pressure gas is input into the cleaning pipe from the air pipe, and while blowing the iron filings inside the drill hole, the inside of the drill hole is brushed, which can effectively reduce the iron filings inside the drill hole.
