Description

Technical Field

[0001] This utility model relates to the field of lathe tool installation technology, and in particular to a fine-tuning device for CNC lathe tool fixture. Background Technology

[0002] A lathe is a machine tool that mainly uses cutting tools to machine rotating workpieces. The cutting tool needs to be connected and fixed on the lathe using a tool holder and tool box. Traditional tool fixture designs often focus on structural stability and quick tool change.

[0003] However, when faced with complex and ever-changing processing requirements, such as processing workpieces of different shapes and materials, the position and angle adjustment of the cutting tool often appears inflexible. It is often necessary to remove the cutting tool and reposition it, which is cumbersome and makes it difficult to quickly fine-tune the angle of the cutting tool. This, to some extent, limits the processing range and processing accuracy of CNC lathes.

[0004] Or the method of tool adjustment is too simple and cannot meet the most suitable positioning requirements of the tool. For example, the tool angle fine adjustment component of the lathe tool holder with publication number CN217799021 U has the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fine-tuning device for CNC lathe tool fixtures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fine-tuning device for a CNC lathe tool holder includes a tool box and a tool body. Mounting mechanisms are provided on opposite sides of the tool box. A tool holder is located inside the tool box, and a mounting groove is provided on the side wall of the tool holder. The tool body is mounted inside the mounting groove, and two fixing bolts are threaded through the tool body and screwed onto the inner wall of the mounting groove. A movable groove is provided on the inner top wall of the tool box. A movable column is fixed to the top of the tool holder and is located inside the movable groove. First adjustment mechanisms extending into the movable groove are provided on opposite side walls of the tool box, and these first adjustment mechanisms abut against the movable column. Two second adjustment mechanisms extending into the tool box are provided on the side wall of the tool box away from the tool holder, and these two second adjustment mechanisms are respectively located on both sides of the tool holder and abut against the tool holder.

[0008] As a further improvement of this utility model, the mounting mechanism includes a mounting plate fixedly connected to the side wall of the knife box, and two mounting bolts are provided through the mounting plate, the mounting bolts being screwed to the mounting plate.

[0009] As a further improvement of this utility model, the first adjustment mechanism includes a first adjustment screw that passes through the side wall of the knife box, the first adjustment screw is screwed to the knife box, and the first adjustment screw abuts against the moving column.

[0010] As a further improvement of this utility model, the second adjustment mechanism includes a second adjustment screw that passes through the side wall of the blade box. The second adjustment screw is screwed to the blade box, and a top cap is fixed at one end of the second adjustment screw inside the blade box. The top cap abuts against the blade holder.

[0011] As a further improvement of this utility model, a first locking nut is threaded onto the first adjusting screw.

[0012] As a further improvement of this utility model, a second locking nut is threaded onto the second adjusting screw.

[0013] The beneficial effects of this utility model are:

[0014] By setting a moving groove, a moving column, and a first adjustment mechanism, the moving column can move and adjust its position inside the moving groove, and then the position of the moving column is locked by the first adjustment mechanism, thereby flexibly adjusting the position of the tool holder relative to the tool box, and thus adjusting the position of the tool body.

[0015] By setting a second adjustment mechanism, the moving column can rotate inside the moving groove, thereby adjusting the deflection angle of the tool holder. When the tool holder rotates, it can drive the tool body to rotate, allowing for fine-tuning of the tool body's angle.

[0016] This invention allows for flexible adjustment of the position and angle of the tool body, making it highly adaptable and meeting the optimal positioning requirements of the tool. It is also easy to operate and adjust, facilitating user convenience. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A fine-tuning device for a CNC lathe tool holder includes a tool box 1 and a tool body 6. Mounting mechanisms are provided on opposite sides of the tool box 1. Each mounting mechanism includes a mounting plate 2 fixedly connected to the side wall of the tool box 1. Two mounting bolts 3 are threaded through the mounting plate 2 and screwed onto it. A tool holder 4 is provided inside the tool box 1. A mounting groove 5 is provided on the side wall of the tool holder 4. The tool body 6 is installed inside the mounting groove 5. Two fixing bolts 7 are threaded through the tool body 6 and screwed onto the inner wall of the mounting groove 5. A moving groove 12 is provided on the inner top wall of the tool box 1. A moving column 13 is fixed to the top of the tool holder 4 and is located inside the moving groove 12. First adjustment mechanisms extending into the moving groove 12 are provided on opposite side walls of the tool box 1, and these mechanisms abut against the moving column 13. Two second adjustment mechanisms extending into the tool box 1 are provided on the side wall of the tool box 1 away from the tool holder 4, and are respectively located on both sides of the tool holder 4 and abut against it.

[0024] In this utility model, the first adjustment mechanism includes a first adjustment screw 8 that passes through the side wall of the knife box 1. The first adjustment screw 8 is screwed to the knife box 1 and abuts against the moving column 13. A first locking nut 9 is threaded onto the first adjustment screw 8. By tightening the first locking nut 9, the first adjustment screw 8 can be locked to prevent it from loosening and maintain its stability.

[0025] The second adjustment mechanism includes a second adjustment screw 10 that runs through the side wall of the tool holder 1. The second adjustment screw 10 is screwed to the tool holder 1. A top cap 14 is fixed to one end of the second adjustment screw 10 inside the tool holder 1. The top cap 14 abuts against the tool holder 4. The side wall of the tool holder 4 that contacts the top cap 14 is an inclined surface. When the top caps 14 on both sides abut against different positions of the inclined side wall of the tool holder 4, the angle of the tool holder 4 inside the tool holder 1 can be adjusted. A second locking nut 11 is threaded onto the second adjustment screw 10. By tightening the second locking nut 11, the second adjustment screw 10 can be locked to prevent the second adjustment screw 10 from loosening and to ensure the stability of the second adjustment screw 10.

[0026] In use, this utility model involves installing the tool body 6 inside the mounting slot 5, fixing the tool body 6 with fixing bolts 7, and then fixing the mounting plate 2 to the CNC lathe with mounting bolts 3.
