Description

Technical Field

[0001] This utility model relates to the field of metal pipe processing technology, specifically to a device for deburring the inner hole of a metal pipe along an abrasive flow. Background Technology

[0002] Metal tubes are common tubular components, including aluminum tubes, copper tubes, and stainless steel tubes. Due to their strength and fluid conductivity, metal tubes are widely used in new energy vehicles, fluid transportation, and other fields. To expand their functions, most existing metal tubes have several small holes (also known as "cross holes") with a diameter of 1 to 2 mm in the tube wall. These small holes need to be processed from the outside to the inside. After the holes are formed, there are burrs on the inner edge of the holes that are difficult to remove, which will affect subsequent use.

[0003] Existing methods mostly involve deburring using abrasive flow equipment. For example, Chinese patent CN205674010U discloses an abrasive flow internal cross-hole deburring and polishing machine. However, this machine uses a small inlet and two outlets as the flow direction of the abrasive flow. The centerline of the small inlet needs to be parallel to the axial direction of the abrasive flow feed pipe, which makes it difficult to position the metal pipe circumferentially and radially. Since the abrasive flow does not build up pressure inside the metal pipe, the grinding effect on the inner edge of the cross-hole per unit time is limited, resulting in low deburring efficiency and making it difficult to adapt to batch deburring operations. Utility Model Content

[0004] The purpose of this invention is to overcome one or more shortcomings of the prior art and to provide a device for deburring the inner hole of a metal pipe along an abrasive flow.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is a deburring device for the inner hole of a metal tube along an abrasive flow, comprising: a base plate and a positioning seat, a support seat, and a supply seat disposed on the base plate. The support seat is located between the positioning seat and the supply seat, and its upper surface has a groove for placing the metal tube. The two ends of the groove pass through the support seat and face the positioning seat and the supply seat respectively. There are multiple support seats arranged at intervals. The side wall of the supply seat is provided with a supply port for supplying the abrasive flow. The supply port corresponds to the position of the groove. The supply seat can slide towards or away from the support seat. When the supply seat and the support seat are close together, the supply seat and the positioning seat clamp the metal tube located in the groove, so that one end of the tube is blocked by the positioning seat and the other end is connected to the supply port.

[0006] Preferably, the cross-sectional shape of the groove matches the cross-sectional shape of the outer wall of the metal tube, and the groove wall has a mating groove that penetrates the support base. When the metal tube is placed in the groove, the cross hole is aligned with the mating groove.

[0007] Preferably, there are multiple grooves spaced apart, and there are multiple supply ports, each corresponding to one of the multiple grooves.

[0008] Preferably, the bottom of the base plate is provided with a first driving device for driving the supply seat to slide. The first driving device is connected to the supply seat through a connecting rod passing through the base plate. The base plate is also provided with an oblong groove for the connecting rod to move.

[0009] Preferably, the positioning seat is slidably disposed in a direction toward or away from the support seat, and the base plate is provided with a second driving device for driving the positioning seat to slide.

[0010] Preferably, the positioning seat is provided with an L-shaped guide hole, which has a first opening and a second opening formed on the upper surface and side wall of the positioning seat, respectively. A sealing plate is provided above the first opening, and the second opening is used to connect with the metal tube.

[0014] More preferably, the adapter is connected to the base plate, and the adapter is provided with a third air blowing device for cleaning the adapter hole.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The present invention provides a metal tube deburring device along the abrasive flow in the inner hole of a cross hole, comprising a base plate and a positioning seat, a support seat, and a supply seat disposed on the base plate. The support seat is located between the positioning seat and the supply seat, and its upper surface has a groove for placing the metal tube. The two ends of the groove pass through the support seat and face the positioning seat and the supply seat respectively. There are multiple support seats arranged at intervals. The side wall of the supply seat has a supply port for supplying abrasive flow, and the supply port is positioned corresponding to the groove. The supply seat can slide towards or away from the support seat. When it approaches the support seat, the supply seat and the positioning seat clamp the metal tube located in the groove, so that one end is blocked by the positioning seat and the other end is connected to the supply port. The abrasive flow supplied by the supply port can enter axially from one end of the metal tube. After pressure is built up in the metal tube, it flows out from the cross hole in the side wall, removing burrs along the inner hole of the cross hole. The metal tube is easy to position and the deburring efficiency is high, which can adapt to batch deburring operations. Attached Figure Description

The support seat 30 is located between the positioning seat 20 and the supply seat 40, and its upper surface has a groove 31 for placing the aluminum tube 1. The two ends of the groove 31 penetrate the front and rear side walls of the support seat 30 and face the positioning seat 20 and the supply seat 40 respectively. There are two support seats 30, which are spaced apart along the front and rear direction. The supply seat 40... The side wall is provided with a supply port 41 for supplying abrasive flow. The supply port 41 corresponds to the position of the groove 31. The supply seat 40 can slide towards or away from the support seat 30. When the supply seat 40 and the support seat 30 are close together, the supply seat 40 and the positioning seat 20 clamp the aluminum tube 1 located in the groove 31, so that one end of it is blocked by the positioning seat 20 and the other end of it is connected to the supply port 41 on the supply seat 40. When the supply seat 40 and the support seat 30 are far apart, the two ends of the aluminum tube 1 are not restricted and the aluminum tube 1 can be taken out and put in.

[0024] The advantage of this design is that when the supply seat 40 and the support seat 30 are close together, the abrasive flow supplied by the supply port 41 can enter axially from one end of the aluminum tube 1, and after pressure is built up inside the aluminum tube 1, it flows out from the cross hole 2 on the side wall to remove the burrs on the inner edge of the cross hole 2. The aluminum tube 1 is easy to position and has high deburring efficiency, which can adapt to batch deburring operations.

The adapter seat 50 has an adapter hole 51. When the supply seat 40 and the support seat 30 are close together, one end of the adapter hole 50 is connected to the supply port 41 and the other end is connected to the aluminum tube 1. The adapter seat 50 is connected to the base plate 10. The adapter seat 50 is provided with a third air blowing device 52 for cleaning the adapter hole 51.

[0029] It should be noted that the upper surface of the base plate 10 is also provided with a linear guide rail 15 for sliding the positioning seat 20 and the feeding seat 40. The linear guide rail 15 is provided with a bellows cover. The upper surface of the feeding seat 40 is provided with an abrasive conveying pipe connector 42 that communicates with the feeding port 41. The base plate 10 is provided with a square hole 16 for recycling the abrasive flow. The square hole 16 is located between the positioning seat 20 and the adapter seat 50. The support seat 30 is also provided with a fourth air blowing device 33 for cleaning the groove 31 and the mating groove 32.
