Description

Technical Field

[0001] The utility model relates to the technical field of drilling processing equipment, in particular to a drilling machine. 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

[0032] 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.

Specifically, the sliding connection structure between the bottom end of the support and the upper end surface of the base is composed of a slide rail and a slider arranged therebetween, and the transverse driving assembly 200 is fixedly connected to the support to drive the support to move transversely back and forth along the base.

[0036] Combined with reference to Figure 5 and 7 As shown, specifically, the transverse drive assembly 200 includes a transverse drive motor 201, a synchronous pulley 202, a synchronous belt 203, a first ball screw 204 and a first ball screw nut 205.

A pair of synchronous pulleys 202 are rotatably mounted at the output end of the transverse drive motor 201 and one end of the first ball screw 204, respectively, and the synchronous belt 203 is mounted on the pair of synchronous pulleys 202.

[0037] When in use, the transverse drive motor 201 drives the synchronous belt 203 to rotate, and the rotating synchronous belt 203 drives the first ball screw 204 to rotate. The rotating first ball screw 204 drives the first ball screw nut 205 to move laterally, thereby causing the support to move back and forth laterally along the base.

[0038] See attached Figure 1 and 2 As shown, the drilling and tapping assembly 100 in this embodiment is vertically slidably mounted on the support through a movable frame, so that the drilling and tapping assembly 100 can be vertically lifted and moved relative to the support. Figure 3 and 5 As shown, the lifting drive assembly 300 includes a lifting drive motor 301, a second ball screw 302 and a second ball screw nut 303. A vertical sliding connection is formed between the movable frame and the support through a slide rail. The second ball screw nut 303 is fixedly connected to the side of the movable frame. The lifting drive motor 301 is fixedly installed on the top of the support. The second ball screw 302 is vertically rotatably installed on the support. The lifting drive motor 301 is connected to the second ball screw 302, and the second ball screw nut 303 is installed on the second ball screw 302.

[0039] When in use, the lifting drive motor 301 drives the second ball screw 302 to rotate, and the second ball screw 302 in the rotating state further drives the second ball screw nut 303 to move up and down along the support, and the second ball screw nut 303 in the lifting and moving state further drives the movable frame to move up and down, and the movable frame in the lifting and moving state further drives the synchronous belt 203 to drive the drilling and tapping assembly 100 to move synchronously.

[0040] See attached Figure 1 and 2 As shown, when the drilling machine in this embodiment is in use, the driving motor rotates, and the power output by the driving motor drives the first gear shaft 102 to rotate through the coupling 1064. The first gear shaft 102 in a rotating state further drives the second gear shaft 104 to rotate through the transmission assembly 103. The rotating second gear shaft 104 further drives the chuck 105 to rotate. The rotating chuck 105 further drives the drill bit to perform drilling operations. When the drilling angle of the chuck 105 needs to be adjusted, for example, the chuck 105 is changed from a vertical processing state to a horizontal and transverse processing state, the reversing motor 1061 drives the reversing bevel pinion 1063, and the reversing bevel pinion 1063 in the rotating state further drives the reversing bevel gear 1062 meshing therewith to rotate, and the reversing bevel gear 1062 in the rotating state further drives the bevel gear group mounting housing 108 to rotate, and the bevel gear group mounting housing 108 in the rotating state further drives the chuck 105 therein to rotate synchronously, so that the chuck 105 in the vertical state is changed to the horizontal and transverse chuck 105 processing state; conversely, the chuck 105 in the horizontal and transverse state is changed to the chuck 105 in the vertical state, and its working principle is the same as above, and it will not be repeated here.
