Description

Technical Field

[0001] This utility model belongs to the field of vertical drilling machine technology, and in particular relates to a vertical drilling machine with a dustproof structure. Background Technology

[0002] A vertical drilling machine is a drilling machine with a vertically arranged spindle and a fixed center position; it is commonly used in machinery manufacturing and repair shops to process holes in small and medium-sized workpieces.

[0003] For example, patent CN218775738U discloses a vertical drilling machine for machining, relating to the field of vertical drilling machine protection technology; while this utility model includes a vertical drilling machine body; in use, when an external object impacts the bottom of the vertical drilling machine body, the external object first applies pressure to the extrusion rubber plate, thereby pushing the extrusion rubber plate and moving it toward the vertical drilling machine body. When the extrusion rubber plate moves toward the vertical drilling machine body, one side of the extrusion rubber plate pushes the extrusion buffer spring, causing it to contract and deform on the rubber buffer rod. Then, the extrusion buffer spring, due to its elastic potential energy, pushes the extrusion rubber plate to move away from the vertical drilling machine body, thereby preventing the external force from continuing to move toward the side closer to the vertical drilling machine body, thus buffering the force applied by the external force and protecting the vertical drilling machine body. Therefore, it greatly reduces the degree of damage to the vertical drilling machine body caused by the impact of external objects.

[0004] Existing vertical drilling machines with dustproof structures generate waste chips and dust during use. These chips and dust enter the interior of the vertical drilling machine, leading to a decrease in its accuracy. Therefore, we propose a vertical drilling machine with an integrated dustproof structure. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a vertical drilling machine with a dustproof structure, thereby preventing waste chips and dust from entering the interior of the vertical drilling machine and causing a decrease in its accuracy.

[0006] In view of this, the present invention provides a vertical drilling machine with a dustproof structure, including a positioning frame, a positioning screw screwed to the inner wall of the positioning frame, a threaded slider threaded to the outer wall of the positioning screw, a connecting rod screwed to both ends of the threaded slider, a telescopic seat screwed to one end of the connecting rod, a limiting groove provided at the connection between the positioning frame and the telescopic seat, a positioning block fixedly connected to the top of the telescopic seat, a dustproof plate fixedly connected to the bottom of the positioning block and fitting against the top of the limiting groove, a positioning plate fitted into the outer wall of the positioning block, and an installation groove fixedly connected to the outer wall of the positioning plate and fitting into the outer wall of the positioning block;

[0007] A drilling assembly, located outside the positioning frame, is used for drilling operations on workpieces.

[0008] Based on the above structure, the threaded slider slides through the connecting rod, driving the telescopic seat to slide along the outer wall of the limiting slide groove. At the same time, the telescopic seat slides synchronously, driving the dustproof plate to slide, thereby performing a dustproof operation when the limiting slide groove moves, preventing dust and debris from entering the interior of the positioning frame. The telescopic seat drives the positioning plate on the outer wall of the positioning block to fit against the outer wall of the workpiece, achieving stable positioning of the workpiece. By setting a mounting groove with a "T" shaped cross-section, it is convenient to replace positioning plates of different shapes.

[0009] Preferably, the limiting slide groove and the dustproof plate are parallel. In this embodiment, the telescopic seat slides and drives the dustproof plate to slide synchronously, thereby performing a dustproof operation when the limiting slide groove moves, preventing dust and debris from entering the interior of the positioning frame.

[0010] Preferably, the cross-section of the mounting groove is T-shaped. In this embodiment, by setting a mounting groove with a T-shaped cross-section, it is beneficial to replace positioning plates of different shapes.

[0011] Preferably, the outer wall of the positioning plate is provided with anti-slip texture. In this embodiment, the telescopic seat drives the positioning plate on the outer wall of the positioning block to fit against the outer wall of the workpiece, thereby achieving stable positioning of the workpiece.

[0012] Preferably, the drilling assembly includes:

[0013] A workbench is fixedly connected to the bottom of the positioning frame.

One end of the guide post is fixedly connected to a protective plate fixedly connected to the outer wall of the lifting plate. In this embodiment, by setting a protective cover, dust prevention operation of the X-axis moving module and the Y-axis moving module is achieved. Then, the pneumatic push rod works to drive the lifting frame to slide vertically along the outer wall of the column through the lifting plate. The sliding of the lifting frame drives the drill bit to approach. Then, the motor works to drive the drill bit to drill a hole in the workpiece. At the same time, the sliding of the lifting frame drives the protective plate to slide synchronously. The sliding of the protective plate drives the guide post to slide along the groove of the guide groove, thereby protecting the column and preventing dust and debris from entering the interior of the column.

[0014] Preferably, the protective cover has a triangular cross-section. In this embodiment, by setting the protective cover, dust prevention operation of the X-axis moving module and the Y-axis moving module can be achieved.

[0015] Preferably, the protective plate is provided in two sets, and the two sets of protective plates are symmetrical about the lifting frame. In this embodiment, the lifting frame slides and drives the protective plate to slide synchronously.

By setting a protective cover 14, the X-axis moving module 12 and the Y-axis moving module 13 are protected from dust.

[0045] Finally, the pneumatic push rod 16 operates by driving the lifting frame 18 to slide vertically along the outer wall of the column 15 via the lifting plate 17. The sliding of the lifting frame 18 causes the drill bit 20 to move closer. Then, the motor 19 operates to drive the drill bit 20 to drill holes in the workpiece.
