Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal material pipe fittings technology, and in particular to a device for drilling curved surfaces of straight pipes. Background Technology
[0002] Metal conduits (also known as metal pipes) are rigid metal pipes used to protect electrical wires or cables. Common materials include steel (such as galvanized steel pipes) and aluminum alloys. They can be divided into rigid conduits and flexible conduits based on their application. Rigid conduits, due to their fixed structure, are often used in building electrical systems. In some applications, it is necessary to machine through holes on the curved surface of the conduit. The main purpose of machining through holes on the curved surface of the metal conduit is to distribute stress and enhance structural strength; it also facilitates connection with other pipe fittings.
[0003] Currently, when drilling holes on the curved surface of a straight tube, the tube needs to be placed on a drilling machine on a lathe. Since the curved surface of the tube is circular, it is relatively difficult to fix it effectively, often resulting in inaccurate drilling positions or tilted holes.
[0004] Therefore, it is desirable to provide a curved surface drilling device for straight pipes, which can solve the above-mentioned technical problems. Utility Model Content

[0035] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0036] Example
[0037] like Figure 1 As shown, this embodiment of a straight pipe curved surface drilling device includes a bracket 1, a fixing mechanism and a drilling mechanism.
[0038] The top of the bracket 1 is provided with a horizontal support surface 2; both the fixing mechanism and the drilling mechanism are provided on the horizontal support surface 2.
[0039] like Figure 2 As shown, the fixing mechanism includes a frame-shaped support base 3, a fixed snap-fit component 4, and a movable snap-fit component 5; the frame-shaped support base 3 is vertically fixed on the horizontal support surface 2, and guide rods 6 are horizontally provided on both the upper and lower parts of the frame-shaped support base 3, with the two guide rods 6 being parallel to each other.
[0040] The fixing fastener 4 is fixed to one end of the outer side of the frame support 3; the inner side of the fixing fastener 4 is recessed inward to form a first V-shaped fastening groove 7.
[0041] The movable latching component 5 includes a support bar 8, two movable latching plates 9, and a driving component; the support bar 8 is slidably mounted on the two guide rods 6, and the movable latching plates 9 are fixed on both the front and rear sides of the support bar 8; the two movable latching plates 9 are respectively located on the front and rear sides of the fixed latching component 4, and the outer surfaces of the two movable latching plates 9 are recessed inward to form a second V-shaped latching groove 10; the two second V-shaped latching grooves 10 are adapted to the first latching groove 7; the driving component is used to drive the support bar 8 to move on the two guide rods 6, moving closer to or away from the fixed latching component 4.
[0042] In this embodiment, the driving component includes a screw 11 and a handle 12; the screw 11 is threaded and passes through the side frame of the frame support 3 near the movable snap-fit 5, and the front end of the screw 11 is rotatably connected to the support bar 8; the handle 12 is located at the rear end of the screw 11; with this configuration, the operator rotates the handle 12, causing the screw 11 to rotate, thereby realizing the linear movement of the support bar 8 on the guide rod, and with the cooperation of the fixed snap-fit 4, the straight pipe is snapped and fixed.
[0043] The drilling mechanism is disposed on one side of the horizontal support surface 2. The drilling mechanism includes a drilling device 13 and a driving device 14. The driving device 14 is used to drive the drilling device 13 to move horizontally on the horizontal support surface along a direction perpendicular to the fixed straight pipe. The center of the cutting head on the drilling device 13 is at the same height as the center of the first locking groove 7. In this embodiment, the driving device 14 is a cylinder.
[0044] In this embodiment, as Figure 3 As shown, a support part 15 is rotatably provided on the horizontal support surface 2; the drilling mechanism is located on the outside of the support part 15; positioning holes (not shown in the figure) are provided at corresponding positions on the horizontal support surface 2 and the support part 15; after the straight pipe is fixed by the fixing mechanism, the support part 15 is rotated so that the positioning holes on the horizontal support surface 2 and the positioning holes on the support part 15 are on the same axis, and the positioning pin 16 is inserted; the driving device is started, and drilling operations can be performed on the corresponding parts of the fixed straight pipe.
[0045] like Figure 4 As shown, when drilling holes in the straight pipe 17, the drilling location of the straight pipe 17 needs to be marked first. The pipe is then placed against the first V-shaped locking groove 7 on the fixing locking member 4, and the straight pipe 17 is moved or rotated so that the marked location is directly in front of the cutting tool on the drilling equipment. The handle 12 is rotated to rotate the screw, thereby enabling the support bar 8 to move linearly on the guide rod 6. With the cooperation of the fixing locking member 4, the straight pipe 17 is locked in place. The drive device 14 and the drilling equipment 13 are started to drill holes at the marked locations on the straight pipe 17. Then, the handle 12 is rotated in the opposite direction to release the moving locking member 5. The straight pipe 17 is then moved so that another marked location is directly opposite the cutting tool on the drilling equipment 13. The straight pipe 17 is then fixed again, and the drive device 14 and the drilling equipment 13 are started to drill holes at the new marked locations on the straight pipe 17. This process is repeated until all drilling operations on the straight pipe are completed.
[0046] In this embodiment, as Figure 2 As shown, the inner walls of the first V-shaped snap-fit groove 7 and the second V-shaped snap-fit groove 10 both have tooth-like structures 18 to prevent the straight pipe from sliding when snapping it in place.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
