Description

Technical Field

[0001] The utility model belongs to the technical field of tool measurement, and particularly relates to a milling cutter measuring device. Background Art

[0002] A milling cutter is a cutting tool used for metal processing, mainly for milling operations. It is usually installed on a milling machine or a numerically controlled machine tool and cuts the workpiece through a rotational motion to machine various complex shapes and surfaces. The cutter diameter and cutter length of the milling cutter are important parameters that determine its applicable range and processing capacity.

[0003] Before installation and during maintenance of the milling cutter, it is necessary to measure the specifications of the cutter diameter and cutter length to ensure the accuracy of machine tool processing. However, in the prior art, the structure of the milling cutter measuring device is relatively complex and bulky. It is necessary to move the milling cutter to be measured to the measuring device for measurement, and the measurement operation is cumbersome, resulting in the need for a dedicated person to operate, thus unable to meet the requirements of on-site rapid detection. Summary of the Invention

[0004] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a milling cutter measuring device, which solves the problems that the milling cutter measuring device is complex and bulky, and the measurement operation is cumbersome and cannot quickly measure the cutter diameter and cutter length on site.

[0005] The technical solution of the utility model: A milling cutter measuring device includes a base, a reference member, and a tool holder seat arranged on the base. The tool holder seat includes a receiving cavity for placing the shank of the milling cutter and a positioning surface for placing the end face of the shank. A counterbore with a radial reference surface and a height reference surface is provided on the base. The radial reference surface is perpendicular to the height reference surface. A first guide rail slider pair and a second guide rail slider pair for linkage control of the reference member are arranged on the counterbore;

[0006] The slider of the first guide rail slider pair slides in a direction perpendicular to the radial reference surface. A first detection device for detecting the distance from the radial reference surface is relatively fixed on the slider of the first guide rail slider pair. The slider of the second guide rail slider pair slides in a direction perpendicular to the height reference surface. A second detection device for detecting the height of the reference member is relatively fixed on the slider of the second guide rail slider pair;

[0007] The reference member includes a front measurement surface and a bottom measurement surface. The bottom measurement surface, the height reference surface, and the positioning surface are parallel to each other. The front measurement surface is parallel to the radial reference surface. When the slider in the first guide rail slider pair is at the bottom of the stroke in the direction close to the tool holder seat, the front measurement surface coincides with the central axis of the receiving cavity.

[0008] By adopting the above technical solution, the handle of the milling cutter is placed in a receiving cavity of corresponding specifications, so that the milling cutter extends upward perpendicular to the positioning surface, and the front measuring surface coincides with the central axis of the receiving cavity, thereby coinciding with the rotation center of the milling cutter, and this time is the zero point of the first detection device, and the specifications of the milling cutter handle are fixed, the length of the part below the handle end face placed in the receiving cavity is fixed, and the distance from the handle end face to the top surface of the milling cutter head is not fixed, therefore, the length of the milling cutter can be obtained by measuring the part of the milling cutter extending out of the positioning surface, and thus the position of the positioning surface can be used as the zero point of the second detection device;

[0009] Therefore, the first detection device and the second detection device respectively use the radial reference surface and the positioning surface as the zero point, and control the movement of the reference part through the linkage of the first guide rail slider pair and the second guide rail slider pair, so that the front measuring surface contacts the edge of the milling cutter blade, and the bottom measuring surface contacts the top surface of the milling cutter head, and the values ​​obtained by the two position detections are compared with the zero point, that is, the actual radius size and tool length value of the milling cutter are obtained, thereby realizing the actual specification measurement of the tool diameter and tool length of the milling cutter. The overall structure is simple and light, and the measurement method only needs to control the movement of the sliders of the first guide rail slider pair and the second guide rail slider pair so that the two measuring surfaces of the reference part are in corresponding positions, which is convenient and simple.

[0010] Further configuration of the utility model: the first guide rail slider pair is arranged on a height reference plane, a first connecting member is fixedly arranged on the slider of the first guide rail slider pair, a mounting seat for fixing the second guide rail slider pair is fixedly arranged on the first connecting member, and a second connecting member for installing a reference member is fixedly arranged on the slider of the second guide rail slider pair.

[0011] With the above further arrangement, the second guide rail slider pair is arranged on the slider of the first guide rail slider pair, so that the second guide rail slider pair as a whole moves with the slider of the first guide rail slider pair, and the reference part and the slider of the second guide rail slider pair are connected and installed through the second connecting part, thereby realizing that the reference part is controlled by the first guide rail slider pair and the second guide rail slider pair to move in two directions respectively, so that the two measuring surfaces of the reference part can be aligned with the milling cutter to realize the measurement of the milling cutter specifications.

[0012] The present invention is further configured as follows: both the first detection device and the second detection device are grating rulers, and the grating rulers include a scale grating and a reading head sliding on the scale grating.

[0013] The above-mentioned configuration is further adopted, and a grating ruler is used as the detection device. The overall design of the grating ruler is relatively compact, easy to install on a plane, and simple to maintain. Usually, only regular cleaning and calibration are required, and it can provide very high measurement accuracy, usually reaching the micron level, making the measurement of milling cutter specifications more accurate.

[0014] A further improvement of the present utility model is as follows: The scale grating of the first detection device is arranged side by side with the first guide rail slider pair, the reading head of the first detection device is fixedly connected to the first connecting member, the scale grating of the second detection device is arranged side by side with the second guide rail slider pair, and the reading head of the second detection device is fixedly connected to the second connecting member.

[0015] With the above further improvement, by arranging the reading head in the grating scale side by side with the movement of the slider in the corresponding guide rail slider pair, the movement distance of the reading head in the grating scale can be the same as that of the slider in the corresponding guide rail slider pair. Thus, the measurement of the milling cutter specification can be achieved by measuring the reading head at the corresponding position in the grating scale.

[0016] A further improvement of the present utility model is as follows: A plurality of mounting holes for changing the mounting position of the reference member are evenly distributed on the second connecting member.

[0017] With the above further improvement, by evenly distributing the mounting holes on the second connecting member, the mounting position of the reference member can be changed, the height of the bottom measurement surface can be altered, so that the measurement range of the milling cutter blade length is changed. Or a reference member with a larger size can be replaced, making the areas of the front measurement surface and the bottom measurement surface larger, enabling more stable contact with the top surface and the edge of the milling cutter blade, and making the measurement result more accurate.

[0018] A further improvement of the present utility model is as follows: The first detection device and the second detection device can be externally connected with a digital display meter.

[0019] With the above further improvement, the detection values corresponding to the first detection device and the second detection device can be directly obtained from the digital display meter, making the detection result more intuitive and concise.

[0020] A further improvement of the present utility model is as follows: Guide rail clamps are arranged on the guide rails of the first guide rail slider pair and the second guide rail slider pair.

[0021] With the above further improvement, by arranging guide rail clamps on the guide rails of the two guide rail slider pairs, firstly, it can prevent the corresponding slider from sliding out of the guide rail and being damaged. Secondly, it can lock the slider after it moves to the corresponding position to prevent the measurement data from being lost and requiring reinstallation of the milling cutter for measurement. Only the slider needs to be moved to the position restricted by the guide rail clamp, and at the same time, the position of the slider is determined. After locking the guide rail clamp, both hands can be freed to move to multiple perspectives to observe the milling cutter measurement position, without having to always support the slider, making the detection more convenient.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0027] It should be noted that in the description of the present utility model, all directional indications (such as up, down, front, back...) are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0028] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. In the description of the present utility model, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] In addition, the technical solutions between various embodiments of the present utility model can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0030] Such as Figures 1 - 3As shown in the figure, a milling cutter measuring device includes a base 1, a reference member 10, and a tool holder 2 disposed on the base 1. The tool holder 2 includes a receiving cavity 21 for placing the shank of the milling cutter and a positioning surface 22 for placing the end face of the shank. In this embodiment, a hole with an inverted conical structure is used as the receiving cavity 21. Since the specifications of the milling cutter shank can be selected, the length of the part of the shank below the end face placed in the receiving cavity 21 is known, while the distance from the end face of the shank to the top face of the milling cutter head is unknown. Therefore, by measuring the part of the milling cutter extending from the positioning surface 22, the length of the milling cutter can be obtained.

[0031] A counterbore 3 with a radial reference surface 31 and a height reference surface 32 is provided on the base 1. The radial reference surface 31 is perpendicular to the height reference surface 32. A first guide rail slider pair 4 and a second guide rail slider pair 7 for linkage control of the reference member 10 are provided on the counterbore 3. A first detection device 5 and a second detection device 6 are respectively and relatively fixedly provided on the first guide rail slider pair 4 and the second guide rail slider pair 7.

[0032] Both the first detection device 5 and the second detection device 6 use grating scales. The grating scale includes a scale grating and a reading head that slides on the scale grating.

[0033] The slider of the first guide rail slider pair 4 slides in a direction perpendicular to the radial reference surface 31. The guide rail of the first guide rail slider pair 4 and the scale grating in the first detection device 5 are arranged side by side. The slider in the first guide rail slider pair 4 and the reading head in the first detection device 5 are fixedly provided with a first connecting member 8 together, realizing the synchronous movement of the reading head in the first detection device 5 and the slider in the first guide rail slider pair 4. The moving distance of the reading head in the grating scale is the moving distance of the slider in the corresponding guide rail slider pair.

[0034] An installation seat 9 and the second detection device 6 are fixedly installed on the first connecting member 8. A second guide rail slider pair 7 is fixedly provided at one end of the installation seat 9 close to the tool holder 2. The guide rail of the second guide rail slider pair 7 and the scale grating of the second detection device 6 are arranged side by side, so that the slider of the first guide rail slider pair 4 and the reading head in the second detection device 6 both slide in a direction perpendicular to the height reference surface 32.

[0035] The slider of the second guide rail slider pair 7 and the reading head in the second detection device 6 are fixedly connected with a second connecting member 13 together. The second connecting member 13 is evenly provided with mounting holes for fixedly setting the reference member 10. By changing the mounting holes, the mounting position of the reference member 10 is changed, and the height of the bottom measurement surface 12 is changed, so that the measurement range of the milling cutter length is changed.

[0036] The reference member 10 includes a front measurement surface 11 and a bottom measurement surface 12. The bottom measurement surface 12, the height reference surface 32, and the positioning surface 22 are parallel to each other. The front measurement surface 11 and the radial reference surface 31 are parallel to each other.

[0037] When the slider in the first guide rail slider pair 4 is located at the bottom of the stroke close to the locking tool seat 2, the front measuring surface 11 coincides with the central axis of the accommodating cavity 21, thereby coinciding with the rotation center of the milling cutter, and this is the zero point of the first detection device 5.

[0038] Furthermore, the first detection device 5 and the second detection device 6 may be externally connected to a digital display, and the detection values ​​corresponding to the first detection device 5 and the second detection device 6 may be directly obtained from the digital display, making the detection results more intuitive and concise.

[0039] Guide rail clamps are provided on the guide rails of the first guide rail slider pair 5 and the second guide rail slider pair 7. Firstly, they can prevent the corresponding slider from sliding out of the guide rail and causing damage. Secondly, they can be locked after the slider moves to the corresponding position to prevent the loss of measurement data and the need to install the milling cutter again for measurement. It is only necessary to move the slider to the position restricted by the guide rail clamp. Finally, when the slider moves to the detection position, the guide rail clamp can be locked, freeing both hands to move to multiple viewing angles to observe the milling cutter measurement position without having to keep supporting the slider all the time, making detection easier.

[0040] Specifically, the shank of the milling cutter is placed in a accommodating cavity 21 of corresponding specifications, the end face of the shank of the milling cutter is placed on the positioning surface 22, and the milling cutter as a whole extends upward perpendicular to the positioning surface 22. The first detection device 5 and the second detection device 6 respectively use the radial reference surface 31 and the positioning surface 22 as zero points, and control the movement of the reference part 10 through the linkage of the first guide rail slider pair 4 and the second guide rail slider pair 7, so that the front measuring surface 11 contacts the edge of the milling cutter blade, and the bottom measuring surface 12 contacts the top surface of the milling cutter head, and the values ​​obtained by detecting the two positions are compared with the zero point, that is, the actual radius size and tool length value of the milling cutter are obtained, thereby realizing the actual specification measurement of the tool diameter and tool length of the milling cutter. The overall structure is simple and light, and the measurement method only needs to control the movement of the sliders of the first guide rail slider pair 4 and the second guide rail slider pair 7 so that the two measuring surfaces of the reference part 10 are in corresponding positions, which is convenient and simple.
