Description

Technical Field

[0001] This utility model belongs to the technical field of cutting tool diameter detection equipment, specifically relating to a cutting tool diameter detection machine with a clamp. Background Technology

[0002] In the tool manufacturing process, the tool diameter directly affects the dimensional accuracy of the workpiece, such as the hole diameter and groove width. Diameter inspection is required to ensure that the dimensions meet the processing requirements and avoid processing defects caused by tool size deviations. Tool diameter measurement methods include tool diameter inspection machines that utilize optical measurement and laser measurement methods. Optical measurement methods use an optical system to project and magnify the diameter value on an eyepiece or display screen, while laser measurement methods use a laser beam to scan the tool and calculate the diameter by the time the beam is blocked.

[0003] When the aforementioned tool diameter measuring machine uses optical and laser measurement methods to measure tool diameter, the tool is fixed to the worktable by a fixture consisting of a conventional screw, slider, and clamping block. Rotating the screw changes the distance between the slider and the clamping block. However, this method has drawbacks: first, it cannot change the tool angle, making it difficult to perform multiple measurements and obtain an average value; second, when changing to different tool sizes, the distance between the slider and the clamping block must be adjusted, and since different tool shapes and sizes require frequent fixture adjustments, misalignment may occur between the tool and the slider and clamping block, necessitating manual replacement of different fixtures. The existing fixtures lack flexibility when dealing with different tools, failing to meet the requirements of angle adjustment and clamping component replacement, thus exhibiting shortcomings.

[0004] Existing tool diameter measuring machines lack a fixture mechanism that allows for adjusting the tool angle and facilitating the replacement of tool clamping components. Therefore, this application proposes a tool diameter measuring machine with a fixture. Utility Model Content

[0029] 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.

[0030] Please see Figures 1 to 8This utility model provides a technical solution: a tool diameter measuring machine with a clamp, including a measuring device for measuring tool diameter, comprising a fixed platform 11, a first position adjusting screw seat 12 and a second position adjusting screw seat 14 fixed to the fixed platform 11 by screws, a tool diameter measuring microscope 13 fixed to the first position adjusting screw seat 12 by screws, a camera frame 15 fixed by screws, and a laser diameter measuring instrument 16. The first position adjusting screw seat 12 and the second position adjusting screw seat 14 utilize the thread transmission principle of a screw and a nut. By rotating the screw, the nut moves, and the nut drives the moving parts on it to move, thereby changing the position. The structure and principle of the first position adjusting screw seat 12 and the second position adjusting screw seat 14 are existing technologies and will not be described in detail in this application. Figure 1 and Figure 2 In this diagram, A represents a cutting tool. When measuring the diameter of tool A, it is positioned between the tool diameter measuring microscope 13 and the laser diameter measuring instrument 16 to facilitate diameter measurement. The support structure includes a screw rod 2 fixed to the fixed platform 11 by screws, a lifting cylinder 3 threadedly connected to the screw rod 2, and a support block 4 threadedly connected to the top of the lifting cylinder 3. A connecting piece is located at the center of the support block 4. By rotating the lifting cylinder 3, it can be vertically raised and lowered along the axis of the screw rod 2, thereby changing the height of the support block 4 and the fixture seat 5, thus changing the height of tool A for easier measurement of different positions on tool A. The support block 4 supports the fixture seat 5. The fixture seat 5 is rotatably connected to the support block 4, allowing for adjustment of the angle of tool A, suitable for various applications. Measurement facilitates the final calculation of the average value, ensuring the accuracy of the measurement results. An electromagnet 6 is embedded inside the clamp base 5. When charged, the electromagnet 6 generates magnetic attraction, adsorbing and fixing itself to the support plate 81, thereby securing the moving plate 8 and maintaining its stability. The symmetrically distributed clamping components include a compression spring 7 connected at one end to the inner wall of the clamp base 5, a moving plate 8 fixedly connected to the other end of the compression spring 7, a support plate 81 fixed to the moving plate 8 by adhesive, clamping blocks 9, and inserts 91. When the tool A is installed, it is positioned between the opposing clamping blocks 9. Under the elastic force of the compression spring 7, the symmetrically positioned clamping blocks 9 clamp the tool A, maintaining its stability. The clamping blocks 9 and the moving plate 8 are separate structures, facilitating manual replacement of the clamping blocks 9 to accommodate tools A of different sizes, thus simplifying operation.

[0031] In this embodiment, a circular plate is provided at the bottom end of the screw column 2. The fixed platform 11 is fixed to the circular plate by screws. The area of ​​the circular plate is larger than the bottom area of ​​the screw column 2, resulting in a large contact area, which ensures the stability of its installation and prevents it from tilting. The centers of the screw column 2, the lifting cylinder 3, the supporting circular block 4, and the clamp seat 5 are on the same vertical axis. The clamp seat 5 is a cylindrical structure with an open top surface. The bottom end of the tool A is inserted into the interior of the clamp seat 5.

[0032] In this embodiment, the outer surface of the lifting cylinder 3 is provided with symmetrically distributed crossbars 31. The ends of the crossbars 31 are connected to the support rods 32 by threaded connection. A magnetic piece 321 is embedded on the top surface of the support rod 32. A magnetic ring 51 is glued to the bottom surface of the clamp seat 5. The magnetic piece 321 and the magnetic ring 51 are fixed by magnetic attraction. The crossbars 31 and the support rods 32 support the magnetic ring 51 and the clamp seat 5 to prevent the clamp seat 5 from tilting. The magnetic ring 51 and the magnetic piece 321 are fixed by magnetic attraction to achieve the function of reinforcing the clamp seat 5.

[0033] In this embodiment, the connecting parts on the support block 4 include a fixed cylinder 101 and a rotating column 102 that are rotatably connected. The fixed cylinder 101 is fixed to the support block 4 by adhesive. The rotating column 102, which is a column structure, passes through the fixed cylinder 101 and is connected to the fixture seat 5 by screw thread. Under the connection between the fixed cylinder 101 and the rotating column 102, the fixture seat 5 is rotatably connected to the support block 4 without affecting the rotation of the fixture seat 5. The rotation of the fixture seat 5 can change the angle of the tool A.

[0034] In this embodiment, the support plate 81 is an inverted "T" shaped structure. The electromagnet 6 and the support plate 81 are fixed by magnetic attraction. The surface of the movable plate 8 is provided with a circular groove a that cooperates with the insertion post 91. The surface of the clamping block 9 is provided with a concave tool groove b. The electromagnet 6 and the support plate 81 are attracted to each other, which can fix the support plate 81 and the movable plate 8, thereby fixing the position of the clamping block 9.

[0035] Working principle and usage process of this utility model:

[0036] When measuring the diameter of tool A, prepare by adjusting the positions of the tool diameter measuring microscope 13 and the laser diameter measuring instrument 16.

[0037] Insert the bottom end of tool A into the fixture 5;

[0038] At the same time, the positions of the moving plate 8 and the clamping block 9 are moved, the compression spring 7 is compressed, and the bottom end of the tool A is placed between the opposing clamping blocks 9.

[0039] Under the elastic force of the compression spring 7, the clamping block 9 clamps the tool A;

[0040] When electromagnet 6 is turned on, it generates magnetic attraction during charging. Electromagnet 6 is attracted and fixed to support plate 81, thereby fixing the moving plate 8 and keeping it stable to prevent the tool A from becoming loose.

[0041] The clamping block 9 and the movable plate 8 are separate structures, which makes it easy to manually replace the clamping block 9 to accommodate different sizes of cutting tools A, and facilitates operation and use.

[0042] By rotating the lifting cylinder 3, the lifting cylinder 3 can be vertically raised and lowered along the axis of the screw column 2, thereby changing the height position of the support block 4 and the fixture seat 5, and thus changing the height position of the tool A. The fixture seat 5 is rotatably connected to the support block 4. The rotation of the fixture seat 5 changes the angle of the tool A, which is suitable for multi-faceted measurement and facilitates the final calculation of the average value of the measurement, ensuring the accuracy of the measurement results, so as to facilitate the detection of different positions on the tool A.

[0043] In summary, the tool diameter measuring machine of this application has a fixture mechanism that allows for adjustment of the tool angle and easy replacement of the tool clamping components. With the coordinated action of the fixture base 5 and the clamping components, the bottom end of the tool is fixed. In addition, the height and angle of the fixture base 5 of this application can be changed, which can change the angle of the tool A, making it suitable for various measurements.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
