Description

Technical Field

[0001] This utility model relates to the field of slotted knife sharpening holders, and in particular to an adjustable angle slotted knife sharpening holder. Background Technology

[0002] In modern manufacturing, grooving cutters are an important cutting tool widely used in metal processing, machinery manufacturing, and other fields. The cutting performance of grooving cutters directly affects machining efficiency and quality; therefore, the grinding process for grooving cutters requires very strict control of the tool angles to ensure that the design parameters of its major and minor clearance angles are effectively achieved.

[0003] Currently, most traditional grooving tool grinding equipment uses a fixed-angle design, which means that the lateral movement of the grinding wheel can only provide a preset angle during the grinding process. This design cannot meet the different requirements of various grooving tools for the primary and secondary clearance angles, resulting in limited angle adjustment of the grooving tool during grinding and making it difficult to achieve the design requirements.

[0004] The primary and secondary clearance angles of a grooving cutter are typically designed based on the specific application and material properties. To ensure effective cutting during use, the primary and secondary clearance angles must be sharpened to precise values. Most existing sharpening stands only offer fixed-angle clamping, failing to flexibly adjust the tool's spatial orientation to accommodate different clearance angle requirements. Grinding a specific primary or secondary clearance angle usually necessitates changing the fixture or manual adjustment, which is cumbersome and compromises accuracy. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable angle groove blade sharpening holder to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable angle groove blade sharpening holder, comprising:

[0007] The mounting base has an arc-shaped groove on its top.

[0008] An adjustment mechanism is mounted on a mounting base and is capable of angular adjustment relative to the mounting base.

[0009] A grooving tool assembly mechanism, which is connected to the top of the adjustment mechanism;

[0010] A positioning bolt, which is threadedly connected to the mounting base, and is used to position the adjustment mechanism.

[0011] A support device is installed at the corner of the bottom of the mounting base.

[0012] Preferably, the adjustment mechanism includes:

[0013] A rotating platform, the bottom of which is provided with an arc surface, and the arc surface cooperates with the inner wall of the arc groove, and both the rotating platform and the mounting base are provided with scale lines on their backs.

[0014] Preferably, the adjustment mechanism further includes:

[0015] A limiting protrusion is connected to the bottom of the rotary table. A groove is provided in the middle of the arc-shaped groove on the mounting base, and the limiting protrusion and the inner cavity of the groove cooperate with each other.

[0016] Preferably, the limiting protrusion has a through slot, and one end of the positioning bolt is fitted with the inner wall of the through slot.

[0017] Preferably, the grooving tool assembly mechanism includes:

[0018] A support platform, which is connected to the top of the adjustment mechanism;

[0019] The mounting bracket is connected to the top of the support platform and has a mounting slot.

[0023] The technical effects and advantages of this utility model are as follows:

[0024] This utility model utilizes a combination of a mounting base and an adjustment mechanism. By cooperating with the arc-shaped groove of the mounting base, the arc angle of the adjustment mechanism relative to the mounting base can be adjusted. This allows the grooving tool assembly mechanism to flexibly adjust its angle relative to the mounting base. Users can precisely adjust the required grinding angle according to the main and secondary clearance angles of different grooving tools. Thus, based on the angle provided by the side swing of the grinding wheel, the grooving tool assembly mechanism provides another angle, ultimately achieving simultaneous and precise grinding of the main and secondary clearance angles of the grooving tool, meeting the needs of tool angle adjustment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figure 1-5 An adjustable-angle slotted blade sharpening holder is shown, comprising: a mounting base 1, the top of which has an arc-shaped slot; an adjustment mechanism 2, which is supported on the mounting base 1 and is capable of angle adjustment relative to the mounting base 1; a slotted blade assembly mechanism 3, which is connected to the top of the adjustment mechanism 2; a positioning bolt 4, which is threadedly connected to the mounting base 1 and is used to position the adjustment mechanism 2; and a support device 5, which is installed at the bottom corner of the mounting base 1, facilitating the rotation of the adjustment mechanism 2 via the mounting base 1. The grooving tool is mounted on the grooving tool. The grooving tool assembly mechanism 3 facilitates the installation of the grooving tool. By adjusting the mechanism 2 and the arc-shaped groove of the mounting base 1, the arc angle of the adjustment mechanism 2 relative to the mounting base 1 can be adjusted. This allows the grooving tool assembly mechanism 3 to be flexibly adjusted relative to the mounting base 1. This enables users to precisely adjust the required grinding angle according to the main and secondary clearance angle requirements of different grooving tools. Thus, based on the angle provided by the side swing of the grinding wheel, the grooving tool assembly mechanism 3 provides another angle, ultimately achieving simultaneous and precise grinding of the main and secondary clearance angles of the grooving tool, meeting the needs of tool angle adjustment.

[0033] The adjustment mechanism 2 includes: a rotary table 21, the bottom of which is provided with an arc surface 211, which cooperates with the inner wall of the arc groove. Due to the arc shape of the arc surface 211, when the position of the arc surface 211 is adjusted relative to the arc groove, it can slide in an arc shape to achieve the angle adjustment of the slotting tool assembly mechanism 3. The back of both the rotary table 21 and the mounting base 1 are provided with scale lines. Through the corresponding cooperation of the two scale lines, the angle of the rotary table 21 can be finely adjusted. A limiting protrusion 22 is connected to the bottom of the rotary table 21. A groove 11 is opened in the middle of the arc groove on the mounting base 1, and the limiting protrusion 22 cooperates with the inner cavity of the groove 11. The groove 11 facilitates the limiting of the movement of the limiting protrusion 22, so that the adjustment mechanism 2 can only slide in an arc shape in the left and right direction relative to the mounting base 1 to achieve the angle adjustment, preventing the adjustment mechanism 2 from sliding in the front and back direction relative to the mounting base 1, making the left and right angle adjustment of the adjustment mechanism 2 more stable. A through slot 221 is provided on the limiting protrusion 22. One end of the positioning bolt 4 fits against the inner wall of the through slot 221. Through the cooperation between the end of the positioning bolt 4 and the inner cavity of the through slot 221, the curvature of the through slot 221 is consistent with the curvature of the arc surface 211. When the rotary table 21 is adjusted in angle, it will drive the limiting protrusion 22 to move synchronously. With the insertion of the positioning bolt 4 into the inner cavity of the through slot 221, the positioning bolt 4 can limit the movement of the limiting protrusion 22, preventing the adjustment mechanism 2 from moving upward and disengaging from the mounting base 1. This makes the sliding of the adjustment mechanism 2 more stable. By rotating the thread of the positioning bolt 4, it can abut against the inner wall of the through slot 221, thereby facilitating the limitation of the position of the adjustment mechanism 2 and preventing the adjustment mechanism 2 from rotating arbitrarily. This allows the adjustment mechanism 2 to be fixed after the position is adjusted.

[0034] Specifically, the grooving tool assembly mechanism 3 includes: a support platform 31, which is connected to the top of the adjustment mechanism 2; and a mounting frame 32, which is connected to the top of the support platform 31. The mounting frame 32 has a mounting groove 321. The support platform 31 facilitates the support of the mounting frame 32, and the mounting groove 321 facilitates the fitting and assembly of the grooving tool, so as to realize the installation of the grooving tool.

[0035] The support device 5 includes: a support foot 51, which is slidably inserted into the corner of the mounting base 1; and an eccentric screw 52, ​​which is threadedly inserted into the mounting base 1 and perpendicularly inserted into the support foot 51. When the eccentric screw 52 is rotated, due to the eccentricity, the mounting axis of the screw will rotate around its geometric center, thereby pushing or pulling the support foot 51 to move relative to the mounting base 1, realizing a small adjustment of the position of the support foot 51. This allows the relative position between the support foot 51 and the mounting base 1 to be adjusted through the eccentric screw 52, ​​further realizing the position adjustment of the mounting base 1.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
