Description

Technical Field

[0001] The utility model relates to the field of frame processing tools, in particular to a corner cleaning tool for a frame. Background Art

[0002] In the frame processing project, especially in the milling process, the corners of the frame are prone to burrs or processing blind spots. Therefore, after the frame processing is completed, the corners need to be cleaned and polished smooth. The existing polishing method generally uses a grinding wheel for polishing, but in the processing of the frame, the same surface also needs to be chamfered, so the tool needs to be changed, which affects the processing efficiency and the tool cost is also high. Utility Model Content

[0003] The main purpose of the utility model is to provide a corner cleaning tool for a frame, aiming to design a tool that can meet the needs of both cleaning corners and chamfering.

[0004] To achieve the above-mentioned purpose, the utility model proposes a corner cleaning tool for a frame, comprising a tool rod, a tool head is provided at the bottom of the tool rod, the tool head is gradually expanded in diameter from the middle to both ends and an avoidance zone is formed in the middle, and a sharp cutting edge is formed at the bottom end of the tool head, and the cutting edge is adapted to the corner shape of the frame.

[0005] In actual processing, the workpiece moves back and forth while the tool bar remains stationary. By setting a cutting edge suitable for the corner shape, when the workpiece moves back and forth, the cutting edge contacts or fits the corner end, thereby achieving burr cleaning and slight grinding of the corner end, thereby ensuring the predetermined processing requirements of the product (bright and burr-free);

[0006] The multifunctional corner cleaning tool can perform milling on the right-angle structure of the product, solving the problem that the right-angle structure of batch products cannot be cleaned. The use of this tool can reduce the number of processing steps and reduce the deviation of processing structure accuracy after multiple clamping of the product.

[0007] This tool has center water lubrication to improve the durability of the tool and improve the surface finish of the product. It also has special curved surface milling processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0015] In addition, if there are descriptions involving "first" or "second" etc. in the embodiments of the utility model, the descriptions of "first" or "second" etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0016] like Figures 1 to 4 As shown, a corner cleaning tool for a frame includes a tool rod 1, a tool head 11 is provided at the bottom of the tool rod 1, the tool head 11 is gradually enlarged in diameter from the middle to both ends and forms an avoidance area 2 in the middle, and a sharp cutting edge 12 is formed at the bottom end of the tool head 11, and the cutting edge 12 is adapted to the corner shape of the frame.

[0017] In actual processing, the workpiece moves back and forth while the tool bar 1 remains stationary. By setting the cutting edge 12 suitable for the corner shape, when the workpiece moves back and forth, the cutting edge 12 contacts or fits with the corner end, thereby achieving burr cleaning and slight grinding of the corner end, thereby ensuring the predetermined processing requirements of the product (bright and burr-free);

[0018] Of course, in one embodiment, the tool can also reciprocate in the vertical direction to meet the corresponding processing requirements.

[0019] The multifunctional corner cleaning tool can perform milling on the right-angle structure of the product, solving the problem that the right-angle structure of batch products cannot be cleaned. The use of this tool can reduce the number of processing steps and reduce the deviation of processing structure accuracy after multiple clamping of the product.

[0021] In the embodiment of the utility model, the horizontal cross-section of the cutter head 11 is rectangular or square. Of course, the cross-section of the cutter head 11 can also be triangular or other shapes to adapt to the corner cleaning of different frames.

[0022] In the embodiment of the present invention, the cutting edge 12 is at 90 degrees.

[0023] In the embodiment of the utility model, the avoidance area 2 is provided with four arc surfaces 21 and an arc-shaped milling edge portion 22 provided between two arc surfaces 21, so that a single tool can process multiple different positions or areas.

[0024] Specifically, the arc surface 21 is provided with a blowing hole 32, and the through hole 31 is vertically provided on the tool rod 1. The blowing hole is connected with the through hole 31, thereby achieving the blowing away or absorption of tiny particles during processing.

[0025] In the embodiment of the utility model, the blowing hole is arranged at an angle, which not only ensures the firmness of the cutter head 11 but also effectively reduces the deviation caused by stress and effectively avoids the problem of high temperature.

[0026] Furthermore, the knife rod 1 is a cylinder.

[0027] In the embodiment of the utility model, the minimum outer diameter of the cutter head 11 is greater than the outer diameter of the tool rod 1, and the upper wall surface and the lower wall surface of the cutter head 11 are planes 100, and the area and shape are suitable, so as to avoid interference in the processing of the cutter head 11 and improve the processing stability. The upper wall surface and the lower wall surface of the cutter head 11 are suitable in shape, which can ensure the durability of the tool and the stability of the axis, and the tool has four cutting edges 12, so the tool cost is lower, and the steps of replacing the tool can be effectively reduced, which effectively improves the production efficiency.
