Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to a rotary drilling device for flange processing. Background Art

[0002] Flange is also called flange flange or flange. Flange is a part that connects shafts to each other. It is used for connecting pipe ends. It is also used as flange on equipment inlet and outlet to connect two equipments. When flange is produced, holes on the flange surface are usually drilled with a drilling device with a servo rotating indexing plate. The flange can be placed on the surface of the indexing plate for indexing drilling.

[0003] At present, when the flange is placed on the dividing plate of the drilling device for drilling processing, the flange can be rotated by the dividing plate for indexing during drilling. When the flange is drilling, coolant will be used to cool the drill bit of the drilling device. When the coolant is sprayed to the contact position between the flange and the drill bit, it will flow out from the surface of the flange and the dividing plate. The long-term downward outflow of cutting fluid from the dividing plate will easily cause the problem of liquid inflow into the rotating seat of the disk body, thereby causing liquid inflow failure of the dividing plate assembly. For this reason, we propose a rotary drilling device for flange processing. Utility Model Content

[0004] The main purpose of the utility model is to provide a rotary drilling device for flange processing, wherein an interception mechanism is arranged at the dividing plate of the rotary dividing processing flange above the drilling platform, so that the coolant flowing down the flange surface can be received by the interception mechanism, and then the dividing plate can rotate the dividing processing flange with the interception mechanism, and the existence of the expansion cylinder can form a splash-proof cavity above the annular cylinder to prevent the coolant at the flange from splashing out of the annular cylinder, and the coolant at the dividing plate will not cause the coolant to enter the rotating gap between the dividing plate and the dividing seat after being intercepted by the interception mechanism, thereby avoiding liquid inlet failure at the dividing plate and the dividing seat used for flange processing, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] Furthermore, a sealing ring is adhered to the outer sleeve of the tube body of the embedded tube embedded in the annular tube, and the sealing ring is adhered to the tube wall of the annular tube; the exposed connection between the embedded tube and the annular tube is adhered and sealed by the sealing ring.

[0008] Furthermore, the outer disk surface of the blocking disk away from the embedded tube is recessed with a disk groove, and a back handle is protruded in the disk groove; the back handle is provided at the blocking disk and can be pinched by hand to rotate the blocking disk.

[0009] Furthermore, the diameter of the ring hole of the sealing rubber ring is smaller than the diameter of the disk body of the indexing disk, and the sealing rubber ring is stretched out from the ring and then sleeved outside the indexing disk; the sealing rubber ring can be stretched out and sleeved outside the indexing disk to maintain sealing.

[0010] Furthermore, the upper ring surface of the support ring is supported by a sealing rubber ring, a plastic connecting ring and a support ring; the support ring can support the sealing rubber ring, the plastic connecting ring and the support ring to maintain sealing.

[0011] Furthermore, a spacing equal to the thickness of the support ring is retained between the support ring and the dividing seat, and the bottom ring surface of the support ring is close to the upper seat surface of the dividing seat; when the dividing plate above the dividing seat rotates, there is a spacing between the support ring and the dividing seat, so that the rotation between the dividing plate and the dividing seat will not be affected.

[0012] Furthermore, the inner cylinder cavity diameter of the expansion cylinder is larger than the cylinder body diameter of the ring cylinder; the expansion cylinder can be inserted outside the ring cylinder after the silicone ring is deformed downward.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

The embedded tube 13 is embedded in the tube wall of the ring tube 9 and is bonded to the tube wall, and a plugging disk 15 is screwed on the outer tube mouth of the embedded tube 13 extending out of the side leakage hole 12.

[0022] The embedded tube 13 is embedded in the annular tube 9 and a sealing ring 14 is bonded to the outer tube of the annular tube 9 . The exposed connection between the embedded tube 13 and the annular tube 9 is bonded and sealed by the sealing ring 14 .

[0023] The outer disk surface of the blocking disk 15 away from the embedded tube 13 is recessed with a disk groove, and a back handle 16 is protruded in the disk groove; the blocking disk 15 is provided with a back handle 16 which can be pinched by hand to rotate the blocking disk 15.
