Description

Technical Field

[0001] The present invention belongs to the field of detection equipment, and particularly relates to a placement table for drill bits, a detection device and a detection method. Background Art

[0002] Parameters such as the inner surface quality, core thickness and core thickness taper of the spiral groove of a drill bit are important indicators for evaluating the chip evacuation performance of the drill bit. In order to observe and detect the foregoing parameters of the spiral groove of the drill bit, professional equipment is required for detection.

[0003] At present, most non-destructive testing equipment on the market generally uses fixed-point observation. If continuous change data inside the spiral groove of the drill bit is desired, multiple multi-point measurements need to be carried out, resulting in low efficiency. Especially when observing micro-drills, due to the small size of the micro-drills themselves, magnifying equipment such as microscopes and ultra-depth-of-field are required for observation. In the case of high magnification, the field of view is small and is greatly affected by the height change of the object, making it difficult to achieve continuous overall observation inside the spiral groove of the micro-drill. Moreover, the lenses of existing detection equipment are generally fixedly arranged, and for drill bits of different sizes and models, relevant equipment often needs to be customized, resulting in high costs.

For example, different specific technical features / embodiments can be combined to form different implementation manners. To avoid unnecessary repetition, the various possible combination manners of the specific technical features / embodiments in the present invention will not be described separately.

[0043] A drill bit placement table provided by an embodiment of the present invention, please refer to Figure 1 and Figure 2, the placement table includes a base 30, an adjusting rod 33, a slide rail 34, a connecting rod assembly, a slider assembly, a first linkage assembly 1 and a second linkage assembly 2. Among them, the adjusting rod 33 and the slide rail 34 are both connected to the base 30; the connecting rod assembly includes a first connecting rod 31 and a second connecting rod 32. The first connecting rod 31 and the second connecting rod 32 are both slidably connected to the base 30. The first connecting rod 31 and the second connecting rod 32 are arranged to slide up and down in a staggered manner, that is, the projections of the first connecting rod 31 and the second connecting rod 32 on the horizontal plane intersect. The first connecting rod 31 can slide along the first direction of the base 30, and the second connecting rod 32 can slide along the second direction of the base 30; the slider assembly includes an adjusting slider 331, a first follower slider 311 and a second follower slider 321. The adjusting slider 331 is slidably connected to the adjusting rod 33. The first follower slider 311 is slidably connected to the first connecting rod 31, and the second follower slider 321 is slidably connected to the second connecting rod 32. And the first follower slider 311 and the second follower slider 321 are both rotatably connected to the adjusting slider 331. The displacement of the adjusting slider 331 will be decomposed and reflected on the first follower slider 311, the second follower slider 321, the first connecting rod 31 and the second connecting rod 32. Specifically, when the adjusting slider 331 slides on the adjusting rod 33, the first follower slider 311 will slide on the first connecting rod 31, and the second follower slider 321 will slide on the second connecting rod 32. At the same time, the first connecting rod 31 and the second connecting rod 32 will slide along the first direction and the second direction on the base 30 respectively. The first linkage assembly 1 includes a first support member 12 and a first rotating shaft 10 for connecting the drill bit 4. The first support member 12 is connected to the first connecting rod 31. The first rotating shaft 10 is rotatably connected to the first support member 12, and the first rotating shaft 10 can slide axially relative to the first support member 12. The first rotating shaft 10 is connected with a first pulling rope 14. The first pulling rope 14 is also connected to the first follower slider 311. When the first follower slider 311 slides on the first connecting rod 31, the first follower slider 311 can drive the first rotating shaft 10 to rotate through the first pulling rope 14, and the drill bit 4 can be connected to the first rotating shaft 10 and rotate therewith. The second linkage assembly 2 includes a second support member 22 and a second rotating shaft 20. The second support member 22 is connected to the second connecting rod 32. The second rotating shaft 20 is rotatably connected to the second support member 22. The second rotating shaft 20 is connected with a second pulling rope 26. The second pulling rope 26 is also connected to the second follower slider 321. And the second rotating shaft 20 is also connected with a third pulling rope 27. The third pulling rope 27 is also connected to the first rotating shaft 10. When the second follower slider 321 slides, the second follower slider 321 can drive the second rotating shaft 20 to rotate through the second pulling rope 26. While the second rotating shaft 20 rotates, it will tighten the third pulling rope 27 to drive the first rotating shaft 10 to slide in the slide rail 34, so that the drill bit 4 connected to the first rotating shaft 10 moves accordingly.In this way, by decomposing the displacement of the adjustment slider 331 into the displacements of the first follower slider 311 and the second follower slider 321, the first follower slider 311 drives the first rotating shaft 10 to rotate through the first pulling rope 14, realizing the rotation of the drill bit 4, while the second follower slider 321 drives the second rotating shaft 20 to rotate through the second pulling rope 26, and the second rotating shaft 20 tightens the third pulling rope 27 to make the first rotating shaft 10 slide in the slide rail 34, realizing the axial movement of the drill bit 4. Thus, the drill bit 4 realizes axial movement while rotating axially. In this way, when observing the drill bit 4 with the detector, with the detector fixed, the drill bit 4 that rotates and moves simultaneously will display the drill bit spiral groove completely and continuously in the detector, realizing fixed-point continuous observation of the drill bit spiral groove, which has the characteristics of simple structure, convenient use and low cost. In specific applications, the sliding speed and sliding distance of the adjustment slider 331 can be reasonably adjusted according to the type and size of the drill bit 4 to adapt to the observation of various drill bits, with good practicability. And the placement table in this embodiment can be used in cooperation with various existing measuring instruments, without the need to be customized for various drill bits, which can reduce the observation cost to a certain extent.

[0044] Please continue to refer to Figure 1 and Figure 2 , as an optional implementation manner of this embodiment, the first linkage assembly 1 further includes a linkage slider 15 that axially moves along with the first rotating shaft 10. The first rotating shaft 10 is rotatably connected to the linkage slider 15. The linkage slider 15 is slidably connected to the slide rail 34, and the linkage slider 15 is connected to the third pulling rope 27. When the second rotating shaft 20 rotates, the second rotating shaft 20 tightens the third pulling rope 27, and the third pulling rope 27 drives the linkage slider 15 to slide in the slide rail 34, making the linkage slider 15 and the first rotating shaft 10 slide in the direction close to the second rotating shaft 20, thereby realizing the axial movement of the first rotating shaft 10 and the drill bit 4.

[0045] Please refer to Figure 2 and Figure 3, as an alternative implementation of this embodiment, the first linkage assembly 1 further includes a first rotating hub 11 and a first pulley member 13. The first rotating hub 11 is connected to the first rotating shaft 10, the first pulley member 13 is connected to the first connecting rod 31. One end of the first pulling rope 14 is connected to the first rotating hub 11, the other end of the first pulling rope 14 is connected to the first follower slider 311, and the first pulling rope 14 is wound around the first pulley member 13. Specifically, the first follower slider 311 and the first pulley member 13 can be located on both sides of the first rotating shaft 10 respectively. The first pulling rope 14 bypasses the first pulley member 13 and is connected to the first follower slider 311 and the first rotating hub 11. When the first follower slider 311 slides, the first pulling rope 14 can drive the first rotating hub 11 to rotate, thereby driving the first rotating shaft 10 to rotate. The first pulley member 13 can change the direction of the pulling force of the first pulling rope 14, and can also make the first follower slider 311 drive the first rotating hub 11 more smoothly, reducing jamming.

[0046] In specific applications, the first rotating shaft 10 can be a spline shaft, the first rotating hub 11 can be a spline hub. The first rotating hub 11 can be connected to the first support member 12 through a thrust bearing. The non-spline groove end of the first rotating shaft 10 can be connected to the linkage slider 15 through a bearing, and a hole for connecting the drill bit 4 is provided at the non-spline groove end of the first rotating shaft 10. During actual use, the rotation speed of the drill bit 4 can be adjusted by replacing the first rotating shaft 10 and the first rotating hub 11 with different sizes, which is beneficial to observing the spiral groove of the drill bit at different rotation speeds.

[0047] Please continue to refer to Figure 2 and Figure 3 , as an alternative implementation of this embodiment, the first support member 12 is slidably connected to the first connecting rod 31, and the first support member 12 can be locked to the first connecting rod 31 through a first locking structure. The first rotating shaft 10 passes through the first support member 12 and can axially move relative to the first support member 12. The first support member 12 has a relief opening 121 for the slide rail 34 to pass through, and the slide rail 34 passes through the relief opening 121 and is slidably connected to the base 30. Specifically, the first locking structure can be a fastener, and the first support member 12 can be locked to the first connecting rod 31 through this fastener. Of course, in other embodiments, the first locking structure can also be other locking methods. The first support member 12 is provided with a through hole for the first rotating shaft 10 to pass through. After the first rotating shaft 10 passes through this through hole, it is connected to the linkage slider 15. The first support member 12 can provide reliable support for the first rotating shaft 10 to ensure the stability of the first rotating shaft 10 during rotation. In specific applications, the first support member 12 can be located between the first rotating hub 11 and the linkage slider 15. Before using the placement table of this embodiment, the positions of the slide rail 34 and the first support member 12 can be adjusted according to the type and size of the drill bit 4 first, and then the first support member 12 is locked to the first connecting rod 31 to adapt to various drill bits.

[0048] Please also refer to Figure 2 and Figure 4 , as an alternative implementation of this embodiment, the second linkage assembly 2 further includes a limit slider 24. The limit slider 24 is connected to the slide rail 34, and the limit slider 24 can be locked to the slide rail 34 through a third locking structure. In this embodiment, the third locking structure can be a fastener, and the limit slider is locked to the slide rail 34 through this fastener. Of course, in other embodiments, the third locking structure can also adopt other locking methods. The second rotating shaft 20 is rotatably connected to the limit slider 24, and the second rotating shaft 20 passes through the limit slider 24 and is connected to the third pulling rope 27. The second rotating shaft 20 can axially slide relative to the second support member 22.

[0049] Specifically, please refer to Figure 1 and Figure 2 , the slide rail 34 is provided with a chute 344 for the linkage slider 15 to slide.

The limit slider 24 can slide along the length direction of the limit guide rail 341, and the limit guide rail 341 restricts the movement freedom of the limit slider 24 in the width direction of the limit guide rail 341. The limit slider 24 is rotatably connected to the second rotating shaft 20, and the limit slider 24 can restrict the axial movement of the second rotating shaft 20.

[0050] Please also refer to Figure 2 and Figure 4 , as an alternative implementation of this embodiment, the second linkage assembly 2 further includes a second rotating hub 21 and a second pulley assembly 23. The second rotating hub 21 is connected to the second rotating shaft 20, the second pulley assembly 23 is connected to the second connecting rod 32. One end of the second pulling rope 26 is connected to the second rotating hub 21, the other end of the second pulling rope 26 is connected to the second follower slider 321, and the second pulling rope 26 is wound around the second pulley assembly 23. Specifically, the second follower slider 321 and the second pulley assembly 23 can be respectively located on both sides of the second rotating shaft 20. The first follower slider 311 and the second follower slider 321 are located on the side close to the adjusting slider 331. The second pulling rope 26 bypasses the second pulley assembly 23 and is connected to the second follower slider 321 and the second rotating hub 21. When the second follower slider 321 slides, the second pulling rope 26 can drive the second rotating hub 21 to rotate, thereby driving the second rotating shaft 20 to rotate. The second pulley assembly 23 can change the direction of the tension of the second pulling rope 26, and can also make the second follower slider 321 drive the second rotating hub 21 more smoothly, reducing jamming.

[0051] In a specific application, the second rotating shaft 20 can be a spline hub, the second rotating hub 21 can be a spline hub, the second rotating hub 21 can be connected to the second support member 22 through a thrust bearing, the non-spline groove end of the second rotating shaft 20 can be connected to the limit slider 24 through a bearing, and a pull rod 25 is provided at the non-spline groove end of the second rotating shaft 20. The pull rod 25 rotates with the second rotating shaft 20, and the pull rod 25 is connected to the linkage slider 15 through a third pull rope 27. During actual use, the rotation speed of the second rotating shaft 20 can be adjusted by replacing the second rotating shaft 20 and the second rotating hub 21 with different sizes, so as to adjust the speed of the linkage slider 15, which is beneficial to observing the drill spiral groove at different moving speeds.

[0052] Please refer to Figure 4 , as an optional implementation manner of this embodiment, the second support member 22 is slidably connected to the second connecting rod 32. The second support member 22 can be locked to the second connecting rod 32 through a second locking structure. The second rotating shaft 20 passes through the second support member 22 and can axially move relative to the second support member 22. Specifically, the second locking structure can be a fastener, and the second support member 22 can be locked to the second connecting rod 32 through this fastener. Of course, in other implementation manners, the second locking structure can also adopt other locking methods. The second connecting rod 32 is provided with a through hole for the second rotating shaft 20 to pass through. After the second rotating shaft 20 passes through this through hole, it is connected to the limit slider 24. The second support member 22 can provide reliable support for the second rotating shaft 20 to ensure the stability of the second rotating shaft 20 during rotation. In a specific application, the second support member 22 can be located between the limit slider 24 and the second rotating hub 21. Before using the placement table of this embodiment, the positions of the second support member 22 and the limit slider 24 can be adjusted according to the type and size of the drill bit first, and then the second support member 22 can be locked to the second connecting rod 32 to adapt to various drill bits.

[0053] Further, please refer to Figure 1 and Figure 2 , as an optional implementation manner of this embodiment, the linkage slider 15 is connected with an elastic reset member 343 for resetting the linkage slider 15, and the first rotating hub 11 is provided with a rotating hub reset member (not shown in the figure) for resetting the first rotating hub 11. Specifically, the elastic reset member 343 can be a spring. One end of the elastic reset member 343 is connected to the linkage slider 15, and the other end of the elastic reset member 343 is connected to a spring connecting plate 342 provided at the end of the slide rail 34. The rotating hub reset member can be a torsion spring. One end of the torsion spring can be connected to the first rotating hub 11, and the other end of the torsion spring can be connected to the first support member 12.

[0054] In a specific application, when the first follower slider 311 slides, it drives the first rotating hub 11 and the first rotating shaft 10 to rotate through the first pulling rope 14, and at the same time twists the rotating hub reset member to make it in a power storage state. When resetting, the rotating hub reset member in the power storage state can reversely rotate the first rotating hub 11 to tighten the first pulling rope 14, so that the first follower slider 311 is reset; when the second follower slider 321 slides, it drives the second rotating shaft 20 to rotate and tightens the third pulling rope 27 through the second pulling rope 26, so that the linkage slider 15 slides towards the direction close to the second rotating shaft 20, and at the same time stretches the elastic reset member 343. When resetting, the stretched elastic reset member 343 drives the linkage slider 15 to slide away from the second rotating shaft 20 and drives the second rotating shaft 20 to rotate reversely through the third pulling rope 27. At the same time, the second rotating shaft 20 tightens the second pulling rope 26 to reset the second follower slider 321. It can be understood that the sliding and resetting of the first follower slider 311 and the second follower slider 321 occur simultaneously. When the first follower slider 311 and the second follower slider 321 are reset, they will simultaneously push the adjusting slider 331 to slide and reset on the adjusting rod 33 and reset the first connecting rod 31 and the second connecting rod 32. In this way, through the combined action of the elastic reset member 343 and the rotating hub reset member, the placement table of this embodiment realizes the automatic reset function, which is convenient for the staff to use. Of course, in other embodiments, the rotating hub reset member can also adopt other devices, such as motor reset, and the rotating hub reset member can also be arranged at other suitable positions.

[0056] Specifically, please continue to refer to and Figure 1 and Figure 5 and, the base 30 may be rectangular, and the front surface of the base 30 is recessed downward to form a mounting groove (not marked in the figure). The opposite side walls of the mounting groove are provided with link chutes 301 at the same height to facilitate the installation of the first connecting rod 31 and the second connecting rod 32. Please refer to Figure 3 and Figure 4, at both ends of the first connecting rod 31, there are first flanges 312. When the first connecting rod 31 slides close to the side wall of the installation groove, the first flanges 312 can abut against the side wall of the installation groove to limit the further sliding of the first connecting rod 31, preventing the first connecting rod 31 from completely adhering to the side wall of the installation groove, thereby preventing the components on the first connecting rod 31 from directly contacting the side wall of the installation groove and ensuring the normal operation of each component. Correspondingly, second flanges 322 are also provided at both ends of the second connecting rod 32.

[0057] More specifically, please refer to Figure 1 , one end of the adjusting rod 33 can be rotatably connected to the bottom of the installation groove, and this end of the adjusting rod 33 can be close to the diagonal of the base 30. The adjusting rod 33 can adjust the angle around this end and can be locked at a specified angle. During use, the angle of the adjusting rod 33 can be correspondingly adjusted according to the different pitches of the drill bit 4. At the same time, in order to facilitate the adjustment of the angle of the angle adjusting rod 33, corresponding angle scales can be provided on the base 30. In specific applications, please refer to Figure 2 As an example direction, when the adjusting rod 33 rotates counterclockwise, the included angle between the adjusting rod 33 and the side of the base 30 is equal to the helix angle of the detected drill bit 4, that is Figure 2 the included angle between the lower side of the base 30 and the adjusting rod 33 in is equal to the helix angle of the drill bit 4 to be detected. Of course, in actual applications, according to the direction of the first linkage assembly 1 and the second linkage assembly 2 and the different structures of the base 30, the definition of the included angle can be adjusted accordingly. And length scales can also be provided on the adjusting rod 33 to facilitate the convenience of manual operation and realize the observation at different magnification ratios; at the top of both sides of the base 30, there are slide rail chutes 302 for the slide rail 34 to slide. The two ends of the slide rail 34 are slidably connected to the slide rail chutes 302. In specific applications, the adjusting slider 331 can be manually slid or can be automatically controlled by a motor or other automation devices to facilitate the operation of the staff.

[0058] The embodiment of the present invention also provides a detection device for a drill bit, including a detector and the above-mentioned placement table for a drill bit. In specific applications, the detector can be a microscope, a high-depth magnification device or other detection instruments. When specifically used, the detector is placed above the placement table, and components such as the slide rail 34, the first support member 12 and the second support member 22 are adjusted to achieve matching to adapt to various detection instruments, which is convenient for the use of the staff and does not need to be specially customized, and can effectively reduce costs.

[0059] The embodiment of the present invention also provides a detection method for a drill bit, using the above-mentioned detection device for a drill bit, including the following steps:

[0060] Connect the drill bit 4 to be detected to the first rotating shaft 10. In this way, when the first rotating shaft 10 rotates, the drill bit 4 to be detected can rotate with the first rotating shaft 10.

[0061] Slide the adjusting slider 331 along the adjusting rod 33. The adjusting slider 331 drives the first follower slider 311 and the second follower slider 321 to slide along the first connecting rod 31 and the second connecting rod 32 respectively, and the first connecting rod 31 and the second connecting rod 32 slide on the base 30.

[0062] The first follower slider 311 drives the first rotating shaft 10 to rotate through the first pulling rope 14 to realize the rotation of the drill bit 4. The second follower slider 321 drives the second rotating shaft 20 to rotate through the second pulling rope 26, and the second rotating shaft 20 tightens the third pulling rope 27 to drive the first rotating shaft 10 to slide in the slide rail 34, so as to realize the axial movement of the drill bit 4 along the slide rail 34.

[0063] Specifically, first connect the drill bit 4 to be measured to the front end of the first rotating shaft 10 (i.e., the end close to the second rotating shaft 20), adjust the positions of the first support member 12 and the second support member 22 and lock them to the first connecting rod 31 and the second connecting rod 32. According to the parameters of the spiral groove on the drill bit 4 to be inspected, adjust the angle of the adjusting rod 33 and lock it. Slide the adjusting slider 331, and the displacement of the adjusting slider 331 on the adjusting rod 33 will be decomposed and reflected on the first follower slider 311 and the second follower slider 321, that is, the first follower slider 311 and the second follower slider 321 will slide with the adjusting slider 331, and at the same time the first connecting rod 31 and the second connecting rod 32 will also slide in the corresponding directions. The first follower slider 311 drives the first rotating hub 11 and the first rotating shaft 10 to rotate through the first pulling rope 14, and at the same time makes the rotating hub reset member enter the energy storage state, and the drill bit 4 located at the front end of the first rotating shaft 10 also rotates accordingly. The second follower slider 321 drives the second rotating hub 21 and the second rotating shaft 20 to rotate through the second pulling rope 26, and at the same time tightens the third pulling rope 27 through the pull rod 25 at the front end of the first rotating shaft 10, so as to drive the linkage slider 15 and the second rotating shaft 20 to slide in the direction close to the second rotating shaft 20 and stretch the elastic reset member 343. At this time, the drill bit 4 will move forward while rotating, and the detector can observe the specific continuous change of the spiral groove of the drill bit; after the observation is completed, under the action of the elastic reset member 343 and the rotating hub reset member, each component including the first rotating shaft 10 and the second rotating shaft 20 will be reset. It should be explained that due to the limitation of the limit slider 24, the second support member 22 and the second rotating hub 21 will move back relative to the second rotating shaft 20, the position of the second rotating shaft 20 will remain unchanged, and the first rotating shaft 10 will slide relative to the first support member 12 and the first rotating hub 11 under the action of the third pulling rope 27 and will not move with the second connecting rod 32.

[0064] A drill bit placement table, a detection device and a detection method provided by an embodiment of the present invention connect a drill bit 4 to be detected to a first rotating shaft 10. An adjustment slider 331 slidably connected to an adjustment rod 33 drives a first follower slider 311 and a second follower slider 321 to slide on a first connecting rod 31 and a second connecting rod 32 respectively, and drives the first connecting rod 31 and the second connecting rod 32 to slide on a base 30 along a first direction and a second direction respectively. When the first follower slider 311 slides, it drives the first rotating shaft 10 through a first pulling rope 14, causing it to rotate and drive the drill bit 4 to rotate axially. At the same time, when the second follower slider 321 slides, it drives a second rotating shaft 20 through a second pulling rope 26, causing the second rotating shaft 20 to rotate and driving the first rotating shaft 10 to slide in a slide rail 34 through a third pulling rope 27, realizing the axial sliding of the drill bit 4. The rotation and sliding of the drill bit 4 are carried out synchronously, facilitating continuous observation of the spiral groove of the drill bit by the detector, with convenient operation, good practicability and low cost.

[0065] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
