Abstract
The invention discloses a metal tube drilling device which comprises a stand, wherein a drill bit driven by a drive device is arranged above the stand, and a metal tube fixing device is arranged at the bottom of the stand. The metal tube drilling device is characterized in that the fixing device comprises a fixing clamp and a supporting arm, a metal tube inner stay rod is horizontally arranged above the supporting arm, the diameter of the inner stay rod is in fit with the diameter of a metal tube center hole, and a hole for enabling the drill bit to pass through is further arranged on the inner stay rod.
Description
Technical field
The present invention relates to a kind of drilling equipment, relate in particular to a kind of metal tube drilling equipment.
Background technology
In recent years; In the manufacture process of air-conditioning, often need use metal tube; When connecting metal tube, not only can use the mode of welding; Also can on metal tube, hole; Metal tube is connected with miscellaneous part with bearing pin by this hole; Usually use drilling equipment to accomplish when at present metal tube being holed; Existing drilling equipment comprises frame, is arranged on the drill bit of frame top and is arranged on the metal tube fixture on the frame; Though this kind drilling equipment can be accomplished the boring of metal tube during use; And efficient is higher; But because metal tube is that hollow-core construction and this kind drilling equipment are only in the external stability of metal tube; So boring the time cause easily hole on the metal tube around concave region appears, thereby influence the quality of metal tube.
Summary of the invention
The metal tube drilling equipment that can not occur concave region on every side in hole when technical problem to be solved by this invention provides a kind of boring.
For solving the problems of the technologies described above; The present invention provides a kind of metal tube drilling equipment; Comprise frame; The top of said frame is provided with the drill bit that a drive unit drives; The bottom of said frame is provided with a metal tube fixture, and said fixture comprises stationary fixture and support arm, and the upper horizontal of said support arm is provided with a metal tube internal overarm support; The diameter of the diameter of said internal overarm support and metal tube centre bore adapts, and also is provided with the hole that supplies said drill bit to pass on the said internal overarm support.
Said drive unit is a cylinder.
Compared with prior art, beneficial effect of the present invention is:
Because metal tube drilling equipment of the present invention is provided with the metal tube internal overarm support, so the inside that internal overarm support is supported on metal tube during boring can prevent effectively that the tube wall of metal tube is recessed, so the present invention when holing the hole around concave region can not appear.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is explained further details
Referring to shown in Figure 1; A kind of metal tube drilling equipment; Comprise frame 1; Above frame 1, be provided with the drill bit 2 that a drive unit drives; The bottom of frame 1 is provided with a metal tube fixture; Fixture comprises stationary fixture 3 and support arm 4; The upper horizontal of support arm 4 is provided with a metal tube internal overarm support 5; The diameter of the diameter of internal overarm support 5 and metal tube centre bore adapts; Also be provided with the hole that supplies drill bit to pass on the internal overarm support 5; Preferred drive unit is a cylinder, can must prevent effectively that the tube wall of metal tube is recessed thereby metal tube internal overarm support 5 is supported on the inside of metal tube when boring.
The hole concave region can not occur on every side when in sum, the present invention holed.
