Description

Technical Field

[0001] The utility model relates to the technical field of machine tool tool parts, in particular to an eccentric adjustable drag tool. Background Art

[0002] The current industry requires high concentricity of the tool tip. Due to the large number of parts involved in a machine, cumulative errors can lead to eccentricity in the final product. The typical solution is to improve part machining accuracy. However, this high precision requirement results in high machining costs and low yield rates.

[0003] Depending on the cutting material and requirements, blades of varying thicknesses are selected. The current solution is to replace the blade head or blade holder to accommodate blades of varying thicknesses. This requires the user to purchase an additional accessory, and both replacement options are prone to loss. Utility Model Content

[0004] The utility model aims to provide an eccentrically adjustable drag knife, which can support the use of blades of different specifications and ensure that the blades are not eccentric. Based on this adjustment method, the installation slots of the blades or more blades can be integrated.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: an eccentrically adjustable drag knife, comprising a handle, a clamp, and a knife handle, wherein the handle is fixedly connected to the knife handle through a thread, the clamp is fixedly installed on the knife handle by a screw, an adjustment top screw sliding groove is provided on the bottom side of the knife handle, a drag knife head is fixed to the bottom end of the knife handle through an adjustment top screw, a top screw adjustment hole is provided at the corresponding position of the adjustment top screw, a blade mounting groove is provided on the top of the drag knife head, a blade is fixed in the blade mounting groove, the drag knife head and the blade are fixedly connected through a top screw, and an adjustment end surface is provided on the side of the drag knife head.

[0006] Furthermore, there is at least one blade mounting slot, including a first blade mounting slot and a second blade mounting slot provided at the center of the top of the drag blade head.

[0007] Furthermore, the thickness of the first blade mounting groove is 0.63 mm, and the thickness of the second blade mounting groove is 1 mm.

[0008] Furthermore, a first adjustment hole and a second adjustment hole are provided on both sides of the first blade installation slot and the second blade installation slot.

[0009] Furthermore, the first adjustment hole and the second adjustment hole are adjustment holes with waist lines.

[0010] Furthermore, the adjusting top screw and the top screw adjusting hole are screwed together via threads.

[0011] This utility model supports the use of blades of different specifications and ensures that the blades are not off-center. Based on this adjustment method, it is possible to integrate blades or install more blades. The waist-shaped adjustment hole and adjustment end surface of the drag blade head make it easier to adjust the blade to the center. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0018] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0020] See also Figures 1 to 4The utility model provides an eccentrically adjustable drag knife, comprising a handle 1, a latch 2, and a handle 3. The handle 1 is fixedly connected to the handle 3 via a thread, and the latch 2 is fixedly mounted to the handle 3 via a screw. A sliding groove for an adjustment screw 7 is provided on the bottom side of the handle 3. A drag knife head 5 is fixed to the bottom end of the handle 3 via the adjustment screw 7. A screw adjustment hole 10 is provided at the corresponding position of the adjustment screw 7. A blade mounting groove is provided at the top of the drag knife head 5, in which a blade 6 is fixed. The drag knife head 5 and the blade 6 are fixedly connected via a latch. An adjustment end surface 11 is provided on the side of the drag knife head 5. The adjustment end surface 11 is a flat surface that can better adjust the center of the blade 6 compared to other contact surfaces. The handle 1 is used to facilitate installation when the drag knife is used in conjunction with a CNC cutting machine; the latch 2 is used to perform a positioning function when the drag knife is used in conjunction with the CNC cutting machine; and the handle 3 connects the various parts and can drive the blade 6 to rotate when used in conjunction with the CNC cutting machine. The drag blade head 5 can be integrated with multiple blade mounting slots according to requirements to enable one drag blade to support multiple different blades 6.

[0021] See also Figure 2 and Figure 3 There is at least one blade mounting slot, including a first blade mounting slot 8 and a second blade mounting slot 9, located in the center of the top of the drag blade head 5. The first blade mounting slot 8 and the second blade mounting slot 9 can be installed with matching blades 6. The thickness of the first blade mounting slot 8 is 0.63 mm, and the thickness of the second blade mounting slot 9 is 1 mm. The blade mounting slots can be installed with one or more blade mounting slots as needed.

[0022] See also Figure 2 and Figure 3 The first blade mounting slot 8 and the second blade mounting slot 9 are both flanked by a first adjustment hole 4 and a second adjustment hole 12. The first adjustment hole 4 and the second adjustment hole 12 are waist-shaped adjustment holes. The first adjustment hole 4 ensures that the drag blade head 5 can move unobstructed in different directions.

[0023] See also Figure 1 The drag blade head 5 is fixed to the knife handle 3 by adjusting the top screw 7, and the adjusting top screw 7 and the top screw adjusting hole 10 are screwed together through threads.

[0024] Working Principle: This drag blade can be adjusted by adjusting the length of the adjustment screw and the adjustment hole around the blade handle to move the drag blade head forward, backward, left, and right, thereby adjusting the offset of the blade center. Based on the blade center adjustment, this drag blade integrates blade mounting slots of various thicknesses to adapt to blades of different specifications without eccentricity.

[0025] When the circumferential adjustment screw 7 is screwed in, the end portion will contact the adjustment end surface 11 and drive the drag blade head 5 to move. The drag blade head 5 is provided with a waist-shaped first adjustment hole 10, which can ensure that the drag blade head 5 can move in different directions without obstruction.

[0026] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
