Description

Device for quickly cleaning inner hole of long shaft workpiece

Technical Field

The utility model belongs to the technical field of the deep hole bores boring machine frock, especially, relate to a bore depth and be greater than 3m, bore hole aperture is phi 30mm ~ phi 100 mm's the device that is used for long axis class work piece to clear up the hole fast.

Background

The deep hole drilling and boring machine mainly processes slender shaft parts, inner holes of the slender shaft parts belong to ultra-long holes, and after drilling and boring are finished, cutting fluid and scrap iron often remain in the inner holes. Because the hole is darker, the clearance degree of difficulty is big. If the cleaning is not carried out in time, the workpiece is inclined in the subsequent transferring process, so that the residual cutting fluid and scrap iron in the inner hole flow out of the inner hole to pollute the ground on site. Meanwhile, when the inner hole is subjected to cold rolling in the subsequent process, the residual scrap iron is attached to the inner hole wall and easily damages the inner wall, and the product is scrapped when the inner hole is serious.

At present, slender axles class part hole is mainly cleared up through utilizing the extension bar through follow-up manual work among the prior art, ties up cotton yarn with extension bar one end, pushes up the other end with cotton yarn from the one end of slender holes, makes a round trip several times, until with the hole clean up. In order to prevent residual cutting fluid and scrap iron from polluting the ground during hoisting, inner hole cleaning needs to be carried out on a deep hole drilling and boring machine. In the clearance process, the deep hole bores the boring machine and can't continue to process next work piece, only clean up transports the back with the work piece, just can continue to process next work piece, seriously influences deep hole bores boring machine machining efficiency, and artifical clearance in-process, extension bar also very easily fish tail hole if the misoperation.

Disclosure of Invention

The utility model aims to overcome the not enough of existence among the prior art and provide a device that is used for long axis class work piece to clear up hole fast of the remaining cutting fluid of quick clearance deep hole and iron fillings, during the clearance, do not occupy deep hole drilling and boring machine process time, and the hole is not by the fish tail when guaranteeing the clearance.

The technical scheme of the utility model as follows: the utility model provides a device that is used for long axle class work piece to clear up hole fast, is including drilling with the drilling rod part, with the quick clearance part that drilling is connected with the drilling rod part, quick clearance part includes the device body, set up in the device body one end outside with the internal thread connection's of drilling with the drilling rod part external screw thread, process threaded hole on device body other end terminal surface, install the bolt in this screw hole, the bolt compresses tightly felt pad on the terminal surface of device body through the packing ring.

The device body is formed by processing a hollow cylinder, and the external thread of the device body is matched with the internal thread of the drill rod part for drilling in a screwing mode.

Holes are processed in the middle of the gasket and the felt pad.

The technical scheme of the utility model produce positive effect as follows: the device body is provided with external threads on the outer surface and is matched with internal threads of a drill rod part for drilling of the deep hole drilling and boring machine in a screwing mode. The quick cleaning part connects the device body, the felt pad and the gasket together by using an M16 bolt. When a workpiece inner hole is machined, the drill bit is arranged at the workpiece outlet end, the drill bit is unscrewed and replaced with the device body of the inner hole cleaning device, the drill rod drives the device body to retreat to the workpiece inlet end along the inner hole, and the inner hole is cleaned up. The utility model has the advantages of simple structure, low requirement for processing precision, short manufacturing period and low cost; when the inner hole is cleaned, a specially-assigned person is not required to clean, so that the labor cost is saved; the inner hole cleaning can be completed by utilizing the tool retracting time of the drilling and boring machine without occupying the processing time of the drilling and boring machine, so that the utilization rate of equipment is greatly improved; when the device is used for cleaning, the inner hole is contacted with the hole wall of the inner hole to form a felt pad, so that the processing quality of the inner hole is protected.

The labels in the figures are: 1. a workpiece with a finished inner hole; 2. a felt pad; 3. a device body; 4. a drill rod portion for drilling; 5. a bolt; 6. a gasket.

Detailed Description

As shown in fig. 1 and 2, the device for quickly cleaning the inner hole of the long shaft workpiece comprises a device body 3, wherein the tail part of the device body is provided with an external thread connected with a drilling rod part (also called a hollow drilling rod) 4 for drilling, the top end of the device body 3 is provided with a threaded hole M16, and holes are formed in the middle positions of a gasket 6 and a felt pad 2 for cleaning.

When in use, the washer and the felt pad 2 for cleaning are connected and clamped with the device body 3 through the M16 compression bolt 5. The outer diameter of the felt pad 2 is larger than the inner hole of the cleaning workpiece. When the deep hole drilling and boring machine finishes processing the inner hole of the workpiece, the drilling cutter body is arranged at the outlet end of the inner hole of the workpiece. At this time, the drill rod fast-forward button is continuously opened, and the drilling cutter body and a small part of the drill rod extend out of the inner hole. The drilling cutter body is dismounted and replaced with the connected cutter body. Open the drilling rod and move back the button soon, the utility model discloses under the pulling force effect of drilling rod, along hole from exit end to entrance point, the hole pore wall is being hugged closely to the felt pad excircle, clears up out the hole with the cutting fluid and the iron fillings of hole.

The utility model is suitable for a deep hole bores boring machine bore hole aperture and is phi 30mm ~ phi 100 mm's processing, when to different processing apertures, need not to make cleaning device again, only need to change with hole aperture match the felt pad can, reduced manufacturing cost. And because the felt pad can not fish tail the hole when clearing up, the unqualified probability of hole significantly reduces, and product quality obtains improving. Unnecessary process time does not need to increase when clearing up the hole, utilizes the drilling cutter body time of moving back the sword and can accomplish the hole clearance, and machining efficiency obtains improving.

The device body is formed by processing a hollow cylinder, and is provided with an external thread used for connecting a drilling rod for drilling and matched with the internal thread of the drilling rod for drilling in a screwing manner. The quick cleaning part consists of a device body, a fixed washer and an M16 bolt, wherein a threaded hole M16 is processed at the top end of the device body and the circle center of the washer respectively, and the M16 bolt is used for connecting the washer with the top end of the device body and clamping a felt pad for cleaning the inner wall of an inner hole.
