Description

Technical Field

[0001] This utility model relates to the field of grooving tool technology, specifically an adjustable grooving tool. Background Technology

[0002] Grooving tools are specialized tools used to cut grooves on the surface of workpieces. They can be divided into four main categories according to processing requirements: end mills, three-sided milling cutters, saw blade milling cutters, and T-slot milling cutters. Their core structure includes end teeth with double to four-flute designs, axial feed capacity, and geometric parameters optimized for different groove shapes.

[0003] In the grooving tool application with application number 202320213768.1, a support base extends radially outward along the tool body to form a support plate, and a clamping base extends radially outward along the tool body to form a clamping plate opposite to the support plate. This allows the tool body to extend axially into the groove of the flange inner hole from the inner hole, or to form a blade support along the radial direction of the flange inner hole groove. By setting the blade on the support plate and the clamping plate, cutting is achieved on the flange inner hole groove, realizing the machining of the flange inner hole groove on a lathe, improving production efficiency and reducing production costs.

[0004] Although the above-mentioned applications meet the user's needs to a certain extent, there are still some defects in the use process. The specific problems are as follows: the grooving tool adopts a single bolt fixing or slot docking method, which lacks a precise pre-positioning structure. When grooving at high speed or processing workpieces with high hardness, the tool is easily subjected to cutting force impact, resulting in loosening or displacement, leading to problems such as grooving size deviation and burrs on the workpiece surface, which seriously affects the processing quality. Based on this, this utility model designs an adjustable grooving tool to solve the above problems. Utility Model Content

[0005] This invention provides an adjustable grooving tool, which can effectively solve the problems mentioned in the background art, such as the lack of a precise pre-positioning structure when the grooving tool adopts a single bolt fixing or slot docking method. When grooving at high speed or processing workpieces with high hardness, the tool is easily loosened or displaced by the cutting force, resulting in problems such as grooving size deviation and burrs on the workpiece surface, which seriously affect the processing quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable grooving tool, including a handle, a grooving blade slidably connected to one end of the handle, and a locking screw threadedly connected to the inside of one end of the handle. The handle is equipped with an extrusion plate that moves with the extrusion screw of the tool holder. The top of the grooving blade is equipped with a rubber block that extrudes the grooving blade. The rubber block is extruded as the extrusion plate moves. The handle is equipped with an adjustable adjustment block that is driven by an adjustment screw.

[0007] An adjustable grooving tool, preferably, has two grooves integrally formed at one end of the handle, and a protrusion integrally formed at the corresponding groove position of the grooving tool.

[0008] An adjustable grooving tool, preferably, has a deformation groove at one end of the handle, and the locking screw passes through the deformation groove and is threadedly connected to the handle.

[0009] An adjustable grooving tool, preferably, has a return spring welded to both ends inside the handle, a limiting post welded to the top of the return spring, the tops of the two limiting posts being fixedly connected by a pressing plate, a driving rod being installed at one end of the top of the pressing plate by a screw, and a rubber block being glued to one end of the driving rod.

[0010] An adjustable grooving tool, preferably, has a limit groove at the position of the limiting post corresponding to the tool handle, and a corresponding groove at the position of the extrusion plate corresponding to the position of the tool handle.

[0011] An adjustable grooving tool, preferably, has a movable groove at one end of the handle corresponding to the position of the drive rod, and the bottom surface of the rubber block is in contact with the top surface of the grooving tool.

[0012] An adjustable grooving tool, preferably, has an adjusting screw threadedly connected to one end of the handle, an adjusting block rotatably connected to the bottom of the adjusting screw, a limit post fixedly connected to one end of the top of the adjusting block, and a pressing frame threadedly connected to the top of the adjusting screw.

[0013] An adjustable grooving tool, preferably, has a limiting groove formed at the position of the adjustment block on the handle, and the outer side of the adjustment block is in contact with the inner wall of the limiting groove.

[0014] An adjustable grooving tool, preferably, wherein the pressing frame is slidably connected to the outside of the limiting post, and one end face of the pressing frame is in contact with the top surface of the driving rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The structure of this utility model is scientific and reasonable, and it is safe and convenient to use. The double fixing structure of the tool ensures the stability during the processing. By rotating the locking screw, the deformation groove on the tool handle is deformed, which forms a strong extrusion on the grooving tool to achieve the main fixing of the tool. In addition, the auxiliary reinforcement structure composed of the return spring, the limiting post, the extrusion plate and the driving rod, under the push of the extrusion screw on the tool, drives the rubber block to compress and further extrude the grooving tool to form a secondary fixing. The pressing frame driven by the adjusting screw can also lock the driving rod a second time. The grooving tool is fixed and constrained from multiple dimensions, which effectively prevents the tool from loosening or displacing when grooving at high speed or under large cutting force, significantly improves the fixing stability of the tool, and ensures the accuracy of grooving and the surface quality of the workpiece. By rotating the adjusting screw, the operator can drive the adjusting block to move smoothly along the limiting groove through the threaded connection between the adjusting screw and the tool handle. This allows for fine adjustments to the position of the tool handle, ensuring that the grooving tool is precisely centered as required for processing. It easily corrects positional problems caused by tool wear or installation deviations, and can quickly adapt to the processing needs of different groove types. This improves the versatility and processing flexibility of the tool, shortens processing preparation time, and increases overall processing efficiency. Attached Figure Description

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example: Figure 1-4As shown, the present invention provides a technical solution: an adjustable grooving tool, including a handle 1, a grooving blade 2 slidably connected to one end of the handle 1, and a locking screw 3 threadedly connected to the inside of one end of the handle 1. The handle 1 has two grooves integrally formed at one end, and the grooving knife 2 has a protrusion integrally formed at the corresponding groove position. When installing the grooving knife 2, the operator moves the grooving knife 2 to move the protrusion into the groove, thereby initially fixing and positioning the grooving knife 2, which is convenient for locking the grooving knife 2 later.

[0020] A deformation groove is provided at one end of the handle 1. The locking screw 3 passes through the deformation groove and is threadedly connected to the handle 1. After the grooving knife 2 is placed at one end of the handle 1, the operator rotates the locking screw 3 to deform the deformation groove, thereby squeezing the grooving knife 2 and fixing it in place.

[0021] Both ends of the handle 1 are welded with return springs 4. The top of the return springs 4 is welded with limiting posts 5. The tops of the two limiting posts 5 are fixedly connected by a pressing plate 6. One end of the pressing plate 6 is fitted with a driving rod 7 by screws. One end of the driving rod 7 is glued with a rubber block 8.

[0022] A limit groove is provided at the position of the limiting post 5 corresponding to the position of the knife handle 1, and a corresponding groove is provided at the position of the extrusion plate 6 corresponding to the position of the knife handle 1, so as to facilitate the movement of the extrusion plate 6 and facilitate the limiting treatment of the extrusion plate 6, and ensure the stability of the movement of the extrusion plate 6.

[0023] A movable groove is provided at one end of the handle 1 corresponding to the position of the drive rod 7. The bottom surface of the rubber block 8 is in contact with the top surface of the grooving knife 2, which can further compress the grooving knife 2 and ensure the stability of the grooving knife 2 when cutting the part.

[0024] The handle 1 has an adjusting screw 9 connected to its interior via a thread. The bottom of the adjusting screw 9 is rotatably connected to an adjusting block 10. One end of the adjusting block 10 is fixedly connected to a limit post 11. The top of the adjusting screw 9 is connected to a pressing bracket 12 via a thread.

[0025] A limiting groove is provided at the position of the tool handle 1 corresponding to the position of the adjusting block 10. The outer side of the adjusting block 10 is in contact with the inner wall of the limiting groove. The limiting post 11 passes through the tool handle 1 and can limit the position of the adjusting block 10 to ensure the stability of the movement of the adjusting block 10.

[0026] The pressing frame 12 is slidably connected to the outside of the limiting post 11. One end face of the pressing frame 12 is in contact with the top surface of the driving rod 7, which limits the pressing frame 12 and prevents it from rotating when it moves. It can also further press the driving rod 7 to ensure the stability of the grooving knife 2.

[0027] After placing the cutting tool on the tool holder, the operator rotates the extrusion screw on the tool holder. This causes the extrusion plate 6 to move, compressing the return spring 4. As the extrusion plate 6 moves, it drives the drive rod 7, which in turn compresses the rubber block 8, further pressing the grooving knife 2. This double-fixation of the grooving knife 2 makes it more stable and ensures the accuracy of its cutting. The operator can also rotate the adjusting screw 9, which, through the threaded connection between the screw 9 and the handle 1, moves the adjusting block 10, allowing for slight adjustments to the handle 1. This ensures the grooving knife 2 is centered, facilitating better part processing. The movement of the adjusting screw 9 also moves the pressing frame 12, further pressing and limiting the drive rod 7, locking it a second time and further ensuring the stability of the grooving knife 2.

[0028] 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. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
