Description

Technical Field

[0001] The utility model relates to the technical field of drilling processing equipment, in particular to a drilling and tapping component. Background Art

[0002] In the process of mechanical processing, it is often necessary to perform drilling and tapping operations on multiple processing surfaces of the processed parts. For example, in the process of processing aluminum profiles, it is often necessary to perform drilling operations on different surfaces of the profiles. The processing angle of the drill bit on the existing drilling and tapping processing equipment is fixed, that is, the processing angle of the processing spindle is in a fixed state, generally vertical angle drilling operation or horizontal angle drilling operation.

[0003] When a part is being processed by an existing drilling and tapping processing equipment, it is often necessary to flip the part so that the surface to be processed is aligned with the processing spindle when drilling and tapping are required on other sides of the part. In the process of flipping and changing the processing side, the fixture used to clamp the part needs to be loosened and re-clamped. In the above process, the positioning reference of the part is likely to change, which in turn easily causes processing errors between the hole positions, affecting the processing accuracy of the part. Secondly, since the clamping fixture needs to be loosened before and after, the processing efficiency of the part is also affected. Summary of the invention

[0004] In view of the defects existing in the prior art, the purpose of the utility model is to provide a drilling and tapping assembly that can realize switching between horizontal drilling and vertical drilling.

[0012] 1. By providing a reversing mechanism, the transmission power between the first gear shaft and the second gear shaft can be output normally, and the chuck on the second gear shaft can be converted into the horizontal drilling angle and the vertical drilling angle, so that the drilling and tapping assembly has good versatility, and can directly perform drilling processing on different processing surfaces of parts, thereby improving processing efficiency;

[0013] 2. The reversing mechanism in this scheme uses a coupling to realize power transmission between the first gear shaft and the second gear shaft, and at the same time, the reversing large bevel gear is installed on the outer periphery of the coupling, and the power output by the reversing motor is transmitted to the reversing large bevel gear through the reversing small bevel gear, and at the same time, the reversing large bevel gear is connected to the second gear shaft, so that when the drilling angle needs to be switched, the power output by the reversing motor can be transmitted to the reversing large bevel gear through the reversing small bevel gear, so that the reversing large bevel gear rotates, thereby driving the drilling direction of the chuck to switch; it can be seen that the reversing mechanism in this scheme is cleverly designed and simple in structure, and can realize the angle switching of the drilling drill bit at a lower cost.

[0024] At the same time, the reversing mechanism 106 is connected to the second gear shaft 104 and is used to drive the second gear shaft 104 to rotate, so as to make the clamping head 105 be in a horizontal position or a vertical position.

[0025] Refer to the attached Figure 3 and 4 As shown, in this embodiment, the reversing mechanism 106 includes a reversing motor 1061, a reversing bevel gear 1062, a reversing bevel pinion 1063 and a connecting mechanism 107. The reversing bevel gear is mounted on the outer surface of the coupling 1064. The reversing bevel pinion 1063 is fixedly connected to the output end of the reversing motor 1061. The reversing bevel pinion 1063 is meshed with the reversing bevel gear 1062. The reversing bevel gear 1062 is connected to the second gear shaft 104 via the connecting mechanism 107.

[0026] Combined with reference to Figure 3 and 4 And attached Figure 5 As shown, the connection mechanism 107 in this embodiment includes a gear shaft fixing seat 1071 , a bearing 1072 , a connection plate 1073 and a bevel gear set mounting housing 108 .

[0027] The gear shaft fixing seat 1071 is rotatably mounted on the outer surface of the first gear shaft 102 through the bearing 1072, that is, the gear shaft fixing seat 1071 is rotatably connected to the outer surface of the first gear shaft 102, and the gear shaft fixing seat 1071 can rotate relative to the outer surface of the first gear shaft 102. At the same time, one end of the gear shaft fixing seat 1071 is fixedly connected to the reversing bevel gear 1062 through the connecting plate 1073, and the connecting plate 1073 is also rotatably connected to the outer surface of the first gear shaft 102, and the other end of the gear shaft fixing seat 1071 is fixedly connected to the bevel gear set mounting housing 108.

[0028] Continue to refer to the attached Figure 3As shown, in the present embodiment, the first gear shaft 102 is connected to the second gear shaft 104 via a transmission assembly 103. Specifically, the transmission assembly 103 includes a first bevel gear 1032 and a second bevel gear 1031. The first bevel gear 1032 is fixedly mounted at the end of the first gear shaft 102, and the second bevel gear 1031 is fixedly mounted at the top of the second gear shaft 104.
