[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 and Figure 2 As shown, a composite tool for processing a hole system according to an embodiment of the utility model comprises a tool rod 1, an alloy drill 2, a countersink 3 and a first clamping shaft 4, wherein the alloy drill 2 is coaxially distributed with the tool rod 1, and the rear end of the alloy drill 2 is inserted into a slot provided on the front end surface of the tool rod 1, a clamping groove is provided on the alloy drill 2, and the first clamping shaft 4 is arranged on the countersink 3, the axial direction of the first clamping shaft 4 faces the radial direction of the tool rod 1, and the first clamping shaft 4 passes through the tool rod 1 and is inserted into the clamping groove.

[0021] In this embodiment, by providing a first clamping shaft 4 on the countersinking cutter 3 and opening a clamping groove on the alloy drill 2, the first clamping shaft 4 is passed through the tool rod 1 along the radial direction of the tool rod 1 and inserted into the clamping groove, the position between the alloy drill 2 and the countersinking cutter 3 can be limited, and the alloy drill 2 and the countersinking cutter 3 can be precisely positioned, ensuring that the alloy drill 2 and the countersinking cutter 3 can simultaneously process the drill hole and the countersink end face.

[0022] At the same time, the countersinking cutter 3 is connected to the alloy drill 2 using the first clamping shaft 4, which is beneficial to enhancing the stability between the countersinking cutter 3, the alloy drill 2 and the tool rod 1, avoiding the offset of the countersinking cutter 3 when processing the hole system, and further ensuring that the alloy drill 2 and the countersinking cutter 3 can simultaneously process the drilled hole and the countersunk end face.

[0023] Optionally, a first mounting groove is formed on the tool rod 1, the countersink 3 is arranged in the first mounting groove, and the first clamping shaft 4 passes through the bottom surface of the first mounting groove and is inserted into the clamping groove.

[0024] In this embodiment, by providing a first mounting groove on the tool bar 1 and setting the countersink 3 in the first mounting groove, the positional relationship of the countersink 3 relative to the tool bar 1 can be accurately defined. Then, by inserting the first clamping shaft 4 into the clamping groove, the positional relationship of the countersink 3 relative to the alloy drill 2 can be further accurately defined, and the alloy drill 2 and the countersink 3 can be accurately positioned, which is conducive to further ensuring that the alloy drill 2 and the countersink 3 can simultaneously process a drill hole and a countersink end surface.

[0025] Alternatively, if Figure 2 As shown, the composite tool of the hole processing system also includes a first push rod 41, a first sliding groove 31 is opened in the countersinking cutter 3, the axial direction of the first sliding groove 31 is toward the radial direction of the tool rod 1, the first clamping shaft 4 is slidably connected to the first sliding groove 31, and a second sliding groove 32 is opened on the side surface of the countersinking cutter 3 away from the tool rod 1, the extension direction of the second sliding groove 32 is parallel to the axial direction of the first sliding groove 31, the first push rod 41 is connected to the first clamping shaft 4, one end of the first push rod 41 is slidably connected to the second sliding groove 32, and the other end of the first push rod 41 is located on the outside of the second sliding groove 32.

[0026] Specifically, the first clamping groove may be interference-fitted with the first sliding groove 31. The axial direction of the first push rod 41 is perpendicular to the axial direction of the first clamping shaft 4.

[0027] In this embodiment, by pushing the first push rod 41 to move in the second sliding groove 32, since the axial direction of the first sliding groove 31 is parallel to the extension direction of the second sliding groove 32, the first push rod 41 can be connected with the first clamping shaft 4 to drive the first clamping shaft 4 to move in the first sliding groove 31. The first sliding groove 31 can be used to limit the movement trajectory of the first clamping shaft 4 to ensure that the first clamping shaft 4 can be accurately inserted into the clamping groove, and the second sliding groove 32 can also be used to limit the movement trajectory of the first push rod 41 to ensure that the first push rod 41 can synchronously drive the first clamping shaft 4 to move along the axial direction of the first sliding groove 31.

[0028] At the same time, one end of the first push rod 41 is slidably connected to the second sliding groove 32, and the other end of the first push rod 41 is located on the outside of the second sliding groove 32, which can facilitate the staff to act on the end of the first push rod 41 located on the outside of the second sliding groove 32, and there is no need to use tools to reach into the second sliding groove 32 to push the first push rod 41, thereby driving the first clamping shaft 4 to move.

[0029] Alternatively, if Figure 2 and Figure 3As shown, the composite tool of the processing hole system also includes a second clamping shaft 5, and a third sliding groove 33 is provided on the countersink 3. The extension direction of the third sliding groove 33 is toward the radial direction of the first push rod 41. The third sliding groove 33 is connected with the second sliding groove 32. The first push rod 41 is configured as a hollow tubular structure, and a bayonet is provided on the side close to the second clamping shaft 5. The second clamping shaft 5 is used to pass through the bayonet and be inserted into the first push rod 41.

[0030] In this embodiment, by providing the third sliding groove 33 on the countersink 3, arranging the second clamping shaft 5 in the third sliding groove 33, and providing the bayonet on the first push rod 41, when the first clamping shaft 4 is inserted into the bayonet, the bayonet on the first push rod 41 is located within the contour range of the first sliding groove 31, and the second clamping shaft 5 is driven through the bayonet to be inserted into the first push rod 41 to limit the first push rod 41. Thus, the first push rod 41 is limited by the second clamping shaft 5, thereby limiting the first clamping shaft 4, thereby establishing a stable connection relationship between the countersink 3 and the alloy drill 2, further achieving precise positioning of the alloy drill 2 and the countersink 3, and further ensuring that the alloy drill 2 and the countersink 3 can simultaneously process the drill hole and the countersink end surface.

[0031] Alternatively, if Figure 2 and Figure 3 As shown, the composite tool of the processing hole system also includes a spring 6, and a second mounting groove is opened on the side wall of the third sliding groove 33. The spring 6 is arranged in the second mounting groove, one end of the spring 6 is connected to the bottom surface of the second mounting groove, and the other end is connected to the second clamping shaft 5. The spring 6 and the second clamping shaft 5 are coaxially distributed.

[0032] In this embodiment, a second mounting groove is opened on the side wall of the third sliding groove 33, and a spring 6 is arranged in the second mounting groove. The elastic force generated by the spring 6 is used to push the second clamping shaft 5 into the clamping groove of the first push rod 41, thereby avoiding separation of the second clamping shaft 5 from the first push rod 41, which is beneficial to ensure the limiting effect of the second clamping shaft 5 on the first push rod 41 and the first clamping shaft 4.

[0033] Alternatively, if Figure 2 and Figure 3 As shown, the composite tool of the processing hole system also includes a second push rod 51, which is connected to the second clamping shaft 5, one end of the second push rod 51 is slidably connected to the third sliding groove 33, and the other end of the second push rod 51 is located on the outside of the third sliding groove 33.

[0034] In this embodiment, by setting up the second push rod 51, it is convenient for the staff to act on the end of the second push rod 51 located outside the third sliding groove 33, without using tools to reach into the third sliding groove 33 to push the second push rod 51, thereby driving the second clamping shaft 5 to move.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
