Description

Technical Field

[0001] This utility model belongs to the field of parts processing and preparation technology, and in particular relates to a chip blowing device for parts processing. Background Technology

[0002] Currently, after CNC machine tools (computer numerical control machine tools) finish machining, a large amount of metal residue often remains on the machining table and around the workpiece. This residue is mostly fine iron filings, aluminum filings, or alloy fragments, mixed with cutting fluid to form a viscous mixture, which needs to be manually removed promptly. This step forces the machining process to be stopped, and the next batch of machining can only continue after the table is manually cleaned. Since stopping the equipment requires activating the corresponding protective devices, and resuming operation also requires restarting the equipment, this greatly affects the machining efficiency of parts. Utility Model Content

[0003] To address the problem described in the background art that current processing equipment requires repeated opening and closing of protective devices and operation of the machine to clean the worktable during continuous processing of different batches of parts, thus affecting processing efficiency, this utility model proposes the following technical solution:

[0004] A chip blowing device for machining parts includes: a tool holder, multiple positioning blocks, and multiple fan blades that match the positioning blocks; one end of the tool holder is rotatably disposed inside a machine tool, and the other end of the tool holder has an outwardly protruding extension; the outer peripheral surface of each positioning block is an inclined surface, and each positioning block is connected to the extension via a connector; each fan blade is movably disposed on the inclined surface of the positioning block, the fixed end of each fan blade has a mounting hole that matches the connector, and the free end of each fan blade is recessed; when the tool holder rotates, the extension drives each fan blade to rotate to complete the chip blowing action.

[0005] Furthermore, the outer peripheral surface of each fan blade is an arc surface, and the installation height of each fan blade is the same.

[0006] Furthermore, the width of the fixed end of each fan blade is smaller than the width of the free end of each fan blade, and the length of the fixed end of each fan blade is smaller than the length of the free end of each fan blade.

[0007] Furthermore, the connector includes a head and a rod that are fixedly connected; the head and the rod are coaxially fixedly connected, and the rod is threadedly connected to the positioning block; the rod includes a threaded area and a blank area, and when the rod passes through the mounting hole, the threaded area enters the positioning block, and the corresponding fan blade is movably limited within the blank area.

[0008] Furthermore, the thickness of the fan blade is less than the length of the blank area, and the diameter of the mounting hole is greater than the diameter of the blank area.

[0009] Furthermore, the fan blades are arranged at intervals on the outer periphery of the extension, and the concave surface of one of the adjacent fan blades is opposite to the convex surface of the other of the adjacent fan blades.

[0010] Beneficial effects: This utility model drives the rotation of each fan blade by rotating the tool holder. After the machining process of the part is completed, the rotation of each fan blade generates wind to blow the part on the operating table, thereby completing the corresponding chip removal action.

[0012] To make the objectives, technical solutions, and advantages of this application clearer, the present invention will be described in further detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention.

[0013] It should be understood that the terms “center,” “upper,” “lower,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0014] Figure 1 This is a schematic diagram of a chip blowing device for parts processing according to an embodiment of the present invention.

[0015] Reference Figure 1 According to an embodiment of the present invention, a chip blowing device for parts processing includes: a tool holder 1, multiple positioning blocks 2, and multiple fan blades 3 that match the positioning blocks 2. One end of the tool holder 1 is fixedly connected to a rotating mechanism inside a machine tool, and the other end of the tool holder 1 protrudes outward to form an extension 11. The outer peripheral surface of each positioning block 2 is an inclined surface, and each positioning block is fixedly connected to the extension 11 by a connector 4, so that each fan blade 3 is movably disposed on the outer peripheral surface of the extension 11. Each fan blade 3 is movably disposed on one of the inclined surfaces of the positioning block 2, and each fan blade 3 has a mounting hole 31 that matches the connector 4 on its fixed end. The free end of each fan blade 3 is recessed inward to form an arc-shaped plate.

[0016] Specifically, the connector 4 includes a head 41 and a rod 42 that are fixedly connected. The head 41 and the rod 42 are coaxially fixedly connected, and the diameter of the head 41 is larger than the diameter of the rod 42. The rod 42 is divided into a threaded area 421 and a blank area 422, wherein the threaded end passes through the mounting hole 31 and is detachably fixedly connected to the corresponding positioning block 2. During the rotation of the handle 1, each fan blade 3 moves to one of the edges of the corresponding blank area 422, thereby causing each fan blade 3 to unfold and form an umbrella-like structure, thus generating wind under the rotation of the handle 1. When the handle 1 stops rotating, each fan blade 3 moves to the other edge of the corresponding blank area 422, and each fan blade 3 droops down, thereby closing each fan blade 3.

[0017] Furthermore, to increase the wind force generated by each fan blade 3 during rotation, in another embodiment, the concave surface of one of adjacent fan blades 3 is positioned opposite the convex surface of the other adjacent fan blade 3. The mounting height on each positioning block 2 is the same, and the mounting height between each fan blade 3 is also the same. In addition, to further increase the flexibility of movement of each fan blade 3, preferably, the thickness of each fan blade 3 is less than the length of the blank area 422, and the diameter of the mounting hole 31 is greater than the diameter of the blank area 422. The length of the free end of each fan blade 3 is greater than the length of the fixed end of each fan blade 3, and the corners of each fan blade 3 are arc-shaped.

[0018] During the part processing, the machine tool's mobile device, operated by a preset processing program, moves the tool holder 1 above the workpiece. Once the machine tool moves above the workpiece, the motor starts, driving the tool holder 1 to rotate. The airflow generated by each fan blade 3 blowing away debris from the worktable completes the chip removal process. After chip removal, the motor stops, and each fan blade 3 hangs down naturally, completing the retraction process.

[0019] In summary, this utility model drives the rotation of each fan blade by rotating the tool holder. After the machining process of the part is completed, the rotation of each fan blade generates wind to blow the part on the operating table, thereby completing the corresponding chip removal action.
