Description

Technical Field

[0001] This utility model relates to the field of cylindrical steel drilling technology, and in particular to an automatic machining and unloading device for the center hole of cylindrical steel. Background Technology

[0002] Cylindrical steel is a common metal material with a circular cross-section. It is usually used to manufacture mechanical parts, bearings, etc. During the processing, it is cut and drilled in a continuous process through the processing production line. A hole is drilled in the center of the cylindrical steel. After processing, the bar needs to be transported to the ground to facilitate the passage of subsequent bars.

[0003] Chinese patent discloses a device for machining center holes in bar stock (authorization announcement number CN206779510U). This patented technology includes a loading rack, a feed rack, and a discharge rack through which bar stock passes sequentially. A drilling device is located on the side of the feed rack in the direction of bar stock feeding. A motor is located at the end of the drilling device away from the feed rack, and a drill bit is mounted on the motor. A distance detection device is located on one side of the drill bit, and a timer is located on the other side. A cooling and cleaning device is located on the side of the feed rack near the drilling device. This utility model's device for machining center holes in bar stock automates the loading, unloading, and drilling processes, provides stable bar stock clamping, high positioning accuracy of the center hole, and includes drill bit cooling and waste chip cleaning functions, thus improving the efficiency of center hole machining and saving manpower.

[0004] This patented technology reduces cleaning work during use, but it still has shortcomings. After drilling the bar stock, it needs to be unloaded to facilitate the subsequent transport of the plate to the drilling position. The lack of an automatic unloading structure increases manpower, additional mechanical handling, and costs. Therefore, those skilled in the art have provided an automatic unloading device for the central hole of cylindrical steel to solve the problems mentioned in the background art. Utility Model Content

[0021] 2. Beneficial effects

[0022] Compared with existing technologies, the advantages of this utility model are:

[0023] This utility model uses a horizontally moving drilling motor to drill a hole in the center of the cylindrical steel at the top of the frame. After drilling, the drilling motor resets to prepare for drilling again.

[0024] Meanwhile, the cylindrical steel after the center hole is processed is lifted by the push rod driven by the push cylinder. The upward extrusion force is passed through the push plate which rotates around the rotating frame, and the cylindrical steel is lifted and pushed. During the pushing process, the cylindrical steel is tilted and rolled off the rotating frame because the push plate is centered on the rotating frame. The cylindrical steel is automatically unloaded, reducing manpower and additional mechanical handling and costs.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] Please see Figures 1-4 As shown, this embodiment is an automatic machining and unloading device for the center hole of cylindrical steel, including a frame 100.

[0041] The drilling structure 200 includes a mounting bracket 201 at the upper end of the frame 100, a clamping cylinder 209 located on one side of the upper end of the mounting bracket 201, a stroke bracket 203 located on one side of the upper end of the mounting bracket 201, a nut located at the lower end of the stroke bracket 203, a propulsion motor 202 located inside one side of the mounting bracket 201, a screw 206 located at the output end of the propulsion motor 202 and rotatably inserted into the nut, and a drilling motor 207 located on one side of the upper end of the stroke bracket 203.

[0042] Inside the frame 100, there are equidistantly distributed conveyor rollers 101 that are rotatably mounted. The side cross-section of the conveyor rollers 101 is V-shaped.

[0043] Two sets of symmetrically distributed sliders 204 are provided at the lower end of the stroke plate, and symmetrically distributed guide rails 205 are provided at the upper end of the frame 100. The sliders 204 are slidably installed on the outer wall of the guide rails 205.

[0044] The mounting bracket 201 has a stroke port 208 inside, and the output end of the drilling motor 207 corresponds to the stroke port 208.

[0045] Use of drilling structure 200;

[0046] The cylindrical steel is conveyed by the conveyor roller 101. When it is located at the stroke frame 203, the clamping cylinder 209 drives the clamping member at the lower end to clamp the cylindrical steel. The propulsion motor 202 drives the screw 206 to rotate. Because the stroke plate slides on the guide rail 205 through the slider 204, the stroke plate is guided by sliding. The screw 206 pushes the nut with a thread, causing the stroke plate to move laterally, which in turn drives the drilling motor 207 to move. The drill bit at the output end of the drilling motor 207 drills a hole at the center of the cylindrical steel, realizing the positioning drilling of the cylindrical steel.

[0047] Example 2

[0048] Please see Figures 1-4 As shown, this embodiment further includes elements beyond those in embodiment 1;

[0049] as well as;

[0050] The feeding structure 300 includes push cylinders 306 that are equidistantly distributed inside the mounting frame 201, a rotating seat 307 that is located on the lower inner wall of the frame 100 and rotatably mounted with the push cylinders 306, a rotating frame 303 that is located on one side of the upper end of the frame 100 and equidistantly distributed, a push plate 302 that is rotatably mounted inside the rotating frame 303, and a push rod 305 that is located on one side of the lower end of the push plate 302 and rotatably mounted with the telescopic end of the push cylinders 306.

[0051] The conveyor rollers 101 and the pusher plate 302 are staggered, and the pusher plate 302 and the rotating frame 303 are both located in the gaps between the conveyor rollers 101.

[0052] An inclined guide plate 301 is provided on one side of the outer wall of the frame 100, a rubber pad 308 is provided on the upper end of the guide plate 301, and a guide surface 304 is provided on the inner wall of the push plate 302.

[0053] The material feeding structure 300 is used;

[0054] After the center hole of the cylindrical steel is machined, the clamping cylinder 209 stops clamping the cylindrical rod, and the pushing cylinder 306 operates, driving the pushing rod 305 to rise. Because the lower end of the pushing plate 302 is rotatably mounted, the pushing plate 302 uses this as the axis of rotation. The pushing cylinder 306 rotates at three points through the rotating seat 307 at the bottom and the rotating mounting of the pushing rod 305. The pushing cylinder 306 is installed at an angle, so that the force point of the pushing rod 305 is in an inclined state, realizing the effective flipping of the pushing plate 302, causing the cylindrical steel to tilt. The cylindrical steel is conveyed to the guide plate 301 through the guide surface 304, thereby guiding and conveying the cylindrical steel. This realizes the automatic unloading of the cylindrical steel after drilling, avoiding the problems of the large weight of the cylindrical steel, which makes manual unloading very inconvenient, and the labor-intensive and inconvenient operation of handling forklifts and similar equipment. The unloading of the processed cylindrical steel is convenient.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0056] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
