Description

Technical Field

[0001] The invention relates to the field of mechanical processing, in particular to a drilling machine. Background Art

[0002] A drilling machine refers to a machine tool that mainly uses a drill bit to process holes on a workpiece. Usually, the rotation of the drill bit is the main motion, and the axial movement of the drill bit is the feed motion. During the processing, the workpiece does not move, and the tool moves, aligns the center of the tool with the center of the hole, and rotates the tool. Conventional drilling machines require workers to clamp and fix the workpiece to be processed with a fixture, and the workpiece needs to be disassembled after drilling is completed. This process wastes time and is not suitable for continuous processing of workpieces. Therefore, in response to the above problems, this application proposes a drilling machine that can continuously drill holes in workpieces. Summary of the invention

[0005] The lifting frame is fixedly connected with a push rod, the fixed frame is rotatably connected with a rotating wheel, the rotating frame is fixedly connected with the rotating wheel, and the rotating wheel is fixedly connected with a plurality of spring pieces, and the plurality of spring pieces are all arranged obliquely.

[0018] The present invention is described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0019] See also Figure 1-4 ,

[0020] A drilling machine includes a fixed frame 101, a hydraulic cylinder 201 is fixedly connected to the fixed frame 101 by bolts, a lifting frame 202 is fixedly connected to the movable end of the hydraulic cylinder 201 by bolts, a first motor 203 is fixedly connected to the lifting frame 202 by bolts, a drill bit 204 is fixedly connected to the output shaft of the first motor 203, a rotating frame 301 is rotatably connected to the fixed frame 101 by bearings, and a plurality of limit slot frames 302 are welded to the rotating frame 301.

[0021] When using the drilling machine, the staff first inserts the steel plate to be processed into a plurality of limit slot frames 302, and then drives the lifting frame 202 to move downward by controlling the contraction of the moving end of the hydraulic cylinder 201. At this time, the drill bit 204 is driven to rotate by the first motor 203, so as to realize the function of drilling holes in the steel plate. After the drilling is completed, by controlling the rotation of the rotating frame 301, another steel plate is rotated to the bottom of the drill bit 204, and then the drill bit 204 can be controlled to continue drilling holes in the steel plate. By controlling the rotation of the rotating frame 301, continuous drilling of the steel plate can be realized, thereby accelerating the drilling efficiency. At the same time, the limit slot frame 302 can limit the steel plate, without the need to manually clamp and fix the steel plate, thereby shortening the processing time.

[0022] See also Figure 3-4 ,

[0023] The lifting frame 202 is fixedly connected with a push rod 104 by bolts, the fixed frame 101 is rotatably connected with a rotating wheel 102 by a bearing, the rotating frame 301 is fixedly connected with the rotating wheel 102 by bolts, and a plurality of spring pieces 103 are welded on the rotating wheel 102, and the plurality of spring pieces 103 are all inclinedly arranged.

[0024] When the lifting frame 202 moves downward, the lifting frame 202 drives the push rod 104 to push one of the spring pieces 103 downward, and the rotating wheel 102 drives the rotating frame 301 to rotate. When the push rod 104 is separated from the spring piece 103, the rotating wheel 102 stops rotating, and the lifting frame 202 continues to move downward to drill the steel plate.

[0025] After the drilling is completed, the lifting frame 202 drives the push rod 104 to move upward. After the push rod 104 contacts the next spring piece 103, the spring piece 103 is compressed, and the rotating wheel 102 will not rotate in the opposite direction. When the lifting frame 202 moves downward again, the lifting frame 202 will drive the push rod 104 to push the next spring piece 103 again to rotate the rotating wheel 102, thereby realizing the function of continuous processing. Through the above structure, the rotating frame 301 can automatically rotate after the steel plate processing is completed, without the need for separate control, so that the overall process is more coherent.

[0026] See also Figure 1-2 ,

[0027] The lower end of the fixing frame 101 is fixedly connected with a collecting box 401 by means of bolts.

[0028] The collecting box 401 is used to collect the strip-shaped debris generated by drilling.

[0029] See also Figure 6-8 ,

[0030] A shell 403 is welded inside the collecting box 401 , an impeller 404 is rotatably connected inside the shell 403 via a bearing, an exhaust port is opened at the upper end of the shell 403 , and a collecting cover 504 is welded at the front end of the shell 403 .

[0031] When drilling a steel plate, negative pressure is generated in the shell 403 by controlling the rotation of the impeller 404, and air can be drawn through the collecting hood 504, so that the granular debris generated by the drilling enters the collecting hood 504 with the air flow, thereby realizing the function of separately collecting the strip debris and the granular debris.

[0032] See also Figure 7 ,

[0033] An isolation net 406 is installed on the shell 403. The isolation net 406 can prevent granular debris from entering the shell 403, thereby preventing the granular debris from wearing the impeller 404, and at the same time facilitates the collection of the granular debris.

[0034] See also Figure 5-6 ,

[0035] A roller 503 is rotatably connected to the fixed frame 101 via a bearing, and a plurality of spiral brushes are arranged on the roller 503 .

[0036] When the drilling of the steel plate is completed, the steel plate moves to the top of the roller 503. By controlling the rotation of the roller 503, multiple spiral brushes come into contact with the surface of the steel plate, thereby removing the debris remaining on the surface of the steel plate. Since the brush is spiral, the steel plate can be detached from the limiting slot frame 302, realizing the function of automatic unloading while cleaning.

[0037] See also Figure 6 ,

[0038] A material guide trough 402 is fixedly connected to the collection box 401 by bolts. The material guide trough 402 can allow the detached steel plates to be discharged through the material guide trough 402, thereby realizing the function of directional material guiding.

[0039] See also Figure 5 ,

[0040] The impeller 404 and the roller 503 are both fixedly connected with pulleys 502 via keys, and the two pulleys 502 are connected via a synchronous belt.

[0041] When the impeller 404 rotates to collect the granular debris, the impeller 404 drives the roller 503 to rotate synchronously through the cooperation of the two pulleys 502 and the synchronous belt, thereby realizing the function of automatic unloading while cleaning.

[0042] See also Figure 5 ,

[0043] The second motor 501 is fixedly connected to the collecting box 401 via bolts, and the impeller 404 is fixedly connected to the output shaft of the second motor 501 via a coupling.

[0044] The second motor 501 drives the impeller 404 to rotate, thereby collecting granular debris and cleaning and unloading.

[0045] See also Figure 6 ,

[0046] The upper end of the collecting cover 504 is tapered to expand the collection range, and the debris can automatically slide down along the inner wall of the collecting cover 504.
