Description

Technical Field

[0001] The present application relates to the technical field of milling cutters, and in particular to a detection device for detecting the stiffness of a micro milling cutter. Background Art

[0002] Micro milling cutters are specialized tools used in milling processes. During quality inspection, screening of micro milling cutters is often difficult due to their small size, high precision, and fragility. In addition to screening micro milling cutters based on size, they also require rigidity testing to ensure they meet production standards.

[0003] Usually, when performing stiffness testing on a micro milling cutter, the testing cylinder is used to push the piston rod out, causing the impact block to hit the head position of the milling cutter to be tested, and finally the milling cutter to be tested is tested to see if it is broken, thereby completing the stiffness test.

[0004] Since the tool diameter of the micro milling cutter is small and the rigidity is low, defective milling cutters are prone to brittle fracture and splashing during collision, and there is a risk that the operator will be scratched by the flying milling cutter fragments. Therefore, the above-mentioned detection device has poor safety. Summary of the Invention

[0005] In order to improve the problem of poor stability and poor detection accuracy in the detection process of micro milling cutters in the existing technology,

[0006] The present application provides a detection device for detecting the stiffness of a micro milling cutter using the following scheme:

[0007] A detection device for detecting the stiffness of a micro milling cutter, comprising:

[0008] base;

[0009] A material placement block is fixedly mounted on the base, wherein a limiting channel is formed through the material placement block, wherein the limiting channel has a head end and a tail end, and the limiting channel is used for slidably placing and limiting the milling cutter;

[0010] A pushing cylinder is fixedly mounted on a base at the tail end of the limiting channel along the axis of the limiting channel, and a pushing head facing the limiting channel is fixedly mounted on the piston rod of the pushing cylinder, wherein the diameter of the pushing head is smaller than the diameter of the limiting channel;

[0011] An impact cylinder is fixedly mounted on a base at the head end of the limiting channel in a direction perpendicular to the axis of the limiting channel, and an impact head is fixedly mounted on the piston rod of the impact cylinder, and the impact head is used to impact the cutter head of the milling cutter extending from the head end of the limiting channel;

[0012] A protective box is slidably mounted on the base at the head end of the limiting channel along the axis of the limiting channel, and the protective box has a first opening for the cutting head to extend into and a second opening for the impact head to extend into;

[0013] A feeding track, wherein the feeding end of the feeding track is located below the outer side of the first end of the limiting channel;

[0014] The protective box has a protective state and an avoidance state. In the protective state, the protective box is located above the feed end of the blanking track, and is used for the cutter head and the impact head to extend into and collide; in the avoidance state, the protective box avoids above the feed end of the blanking track, and is used to avoid the blanking of the milling cutter.

[0015] By adopting the above solution, a protective box is provided in the milling cutter impact area, and the collision area between the milling cutter head and the impact head is located inside the protective box, thereby effectively preventing the broken cutter head from flying and injuring people. In the traditional micro-milling cutter stiffness detection device, the defective milling cutter will produce cracks or even break and splash during the impact test, which makes the operator on the side of the detection device vulnerable to splashing and scratching by milling cutter fragments. In the technical solution of the present application, through the provision of a protective box, an opening for the impact head and the cutter head to enter is reserved on the protective box, so that the micro-milling cutter head collision area is located inside the protective box. On the one hand, it can effectively prevent broken milling cutter fragments from injuring people and effectively improve the safety performance of the detection device; on the other hand, the protective box can accommodate and collect broken milling cutter fragments, reduce the problem of fragments scattered everywhere, and effectively ensure the cleanliness of the detection environment.

[0016] Optionally, a detection module is also included, which is located at the head end of the limiting channel and is used to detect cracks in the milling cutter; the detection module includes a sliding frame slidably installed on a base and a detection camera, and the detection camera is fixedly installed on the sliding frame and can slide to just above the head end of the limiting channel.

[0017] By adopting the above-mentioned solution, a detection module is set at the head end of the limit channel, and the collision result of the milling cutter is automatically and accurately detected by the detection camera. In the traditional milling cutter stiffness testing device, the milling cutter is usually subjected to a stiffness collision test, and then manual observation is performed to determine whether there are cracks on the milling cutter to determine whether the milling cutter is qualified. However, micro milling cutters are small in size, low in stiffness, and easily brittle. The tiny cracks generated by the collision of defective milling cutters are not convenient for naked eye observation, resulting in a high misjudgment rate of manual observation. In the technical solution of the present application, by installing a detection camera above the head end of the limit channel, the cracks of the milling cutter after the collision can be accurately observed, thereby effectively ensuring the accuracy of the detection.

[0018] Optionally, a first bearing roller and a second bearing roller are installed in parallel on the sliding frame, and the first bearing roller and the second bearing roller are arranged parallel to the axis of the limiting channel; the first bearing roller is coaxially connected to a rotating motor, and the rotating motor is slidingly installed on the sliding frame in a direction perpendicular to the axis of the limiting channel; the first bearing roller has a working state in contact with the second bearing roller, and in the working state, a bearing space facing the limiting channel is formed above the first bearing roller and the second bearing roller, and the bearing space is used to receive the milling cutter after the impact test, and the rotating motor works to drive the milling cutter to rotate in the bearing space.

[0019] By adopting the above solution, the milling cutter is supported by the first supporting roller and the second supporting roller, and the rotation of the first supporting roller drives the milling cutter to rotate along its own axis to adjust the angle, thereby realizing the detection of the milling cutter at multiple angles. In some technical solutions, during the process of visual inspection of the milling cutter by a camera, usually only one side of the milling cutter can be observed; in actual working conditions, the gap generated by the milling cutter during the stiffness impact test may appear at any position of the cutter head, so the above observation method has a large possibility of misjudgment. The technical solution of the present application, on the one hand, can fully observe whether there are cracks in the milling cutter by rotating and adjusting the angle of the milling cutter, thereby further improving the detection accuracy; on the other hand, the first supporting roller and the second supporting roller can move closer to or farther away from each other. In actual working conditions, after the detection is completed, the first supporting roller and the second supporting roller move away from each other, causing the milling cutter to fall into the unloading track and unload the material, which is convenient for unloading.

[0020] Optionally, the detection module includes a light source module, and the light source module is arranged on the sliding frame around the carrying space.

[0021] By adopting the above solution, a light source module is provided for use with the inspection camera. The light source module can effectively illuminate the milling cutter within the carrying space, thereby further improving the accuracy of observation. The technical solution of this application uses the light source module to illuminate the carrying space in a surrounding manner, illuminating the upper surface of the milling cutter, thereby performing optical inspection of the upper surface of the milling cutter, thereby further improving the defect detection effect of the milling cutter.

[0022] Optionally, the feed track is arranged vertically, and the discharge of the feed track is connected to a good feed track, a defective feed track and a switch, and the switch is rotatably installed on the discharge end of the feed track, and the switch is used to rotate to guide the milling cutter to the good feed track or the defective feed track.

[0023] By adopting the above-mentioned solution, the vertically arranged unloading track is used to enable the milling cutter products that have completed the inspection to be unloaded under the action of gravity. In the traditional technical solution, the milling cutter is usually transferred to the transport track, and the movement of the transport track drives the milling cutter to move, and a sorting robot is required to sort good products from defective products. The present application unloads the milling cutter through the action of gravity, and the qualified good products are sent to the good product unloading track through the rotation of the switch, and the unqualified defective products are sent to the defective product unloading track. Compared with the traditional solution, the overall unloading mechanism effectively reduces energy consumption and achieves energy-saving effects.

[0024] Optionally, it also includes a storage box for accommodating good products and a first pusher, the storage box slides at the discharge end of the good product discharge rail, the first pusher is arranged in a direction perpendicular to the axis of the good product discharge rail and abuts against the storage box; a plurality of storage cavities arranged along the axis of the good product discharge rail are arranged in parallel in the storage box, and the first pusher works step by step to push the storage cavity to align with the good product discharge rail to receive the good product milling cutter.

[0025] By adopting the above solution, by providing a accommodating box and a first pusher, the accommodating box can be pushed step by step, so that the multiple accommodating cavities are aligned with the discharge ends of the good product unloading rail one by one, so that the good product milling cutters can be stored one by one.

[0026] Optionally, the accommodating cavity has a cavity opening, and a sealing strip for closing all accommodating cavities is slidably installed at the cavity opening; a second pushing piece is provided at one end of the sealing strip in the length direction, and a stop block is provided at the other end, the second pushing piece is used to push the sealing strip to avoid the cavity opening and abut against the stop block, and the first pushing piece works to make the accommodating box and the sealing strip slide relative to each other to close the cavity openings one by one.

[0027] By adopting this solution, a sealing strip is slidably mounted on the cavity opening of the storage box. Before collecting the qualified milling cutters, the second pusher operates to fully open the sealing strip, clearing all cavity openings. As the first pusher moves stepwise to collect the qualified milling cutters one by one, the sealing strip slides relative to the storage box, closing the cavity openings one by one, thereby conveniently sealing the storage box containing the qualified milling cutters.

[0028] Optionally, a silicone cushion is provided at one end of the accommodating cavity away from the cavity opening.

[0029] By adopting the above solution, a silicone cushion pad is set at the end of the accommodating cavity away from the cavity opening, thereby cushioning the impact force between the good milling cutter and the bottom end of the accommodating cavity, thereby reducing the noise generated by the collision, and can effectively protect the milling cutter head and reduce collision damage.

[0030] Optionally, it further includes a carrying platform having an inclined carrying surface, and the accommodating box and the good product unloading rail are both arranged to be inclined in contact with the carrying surface.

[0031] By adopting the above solution, the inclined bearing surface is set so that the pitch inclination angle of the accommodating box and the good product discharge rail is the same. When the accommodating cavity is aligned with the good product discharge rail, the milling cutter can slide into the accommodating cavity from the good product discharge rail without jamming, reducing the collision of the milling cutter at the opening of the accommodating cavity and ensuring the smoothness of collecting good products.

[0032] Optionally, a positioning protrusion is provided on the supporting platform at the discharge end of the good product discharge rail, and a plurality of positioning grooves are provided at the bottom of the accommodating box corresponding to the accommodating cavity one by one, and the positioning protrusion slides into the positioning groove so that the accommodating cavity faces the good product discharge rail.

[0033] By adopting the above solution, through the cooperation of the positioning protrusion and the positioning groove, each accommodating cavity can be accurately aligned with the discharge end of the good product discharge rail, thereby effectively ensuring the accuracy of the product entering the accommodating cavity from the good product discharge rail.

[0034] In summary, this application has at least the following beneficial technical effects:

[0035] 1. A protective box is provided in the impact area of ​​the milling cutter, and the collision area between the milling cutter head and the impact head is located inside the protective box, thereby effectively preventing the broken cutter head from flying and injuring people. In traditional micro-milling cutter stiffness detection devices, defective milling cutters will produce cracks or even break and fly during the impact test, which makes the operator on the side of the detection device vulnerable to flying and scratching by milling cutter fragments. In the technical solution of the present application, through the provision of a protective box, an opening for the impact head and the cutter head to enter is reserved on the protective box, so that the collision area of ​​the micro-milling cutter head is located inside the protective box. On the one hand, it can effectively prevent broken milling cutter fragments from injuring people and effectively improve the safety performance of the detection device; on the other hand, the protective box can accommodate and collect broken milling cutter fragments, reduce the problem of fragments scattered everywhere, and effectively ensure the cleanliness of the detection environment;

[0036] 2. The milling cutter is supported by the first supporting roller and the second supporting roller, and the rotation of the first supporting roller drives the milling cutter to rotate along its own axis to adjust the angle, thereby enabling detection of the milling cutter at multiple angles. In some technical solutions, during the process of visual inspection of the milling cutter by a camera, usually only one side of the milling cutter can be observed; in actual working conditions, the gaps generated by the milling cutter during the stiffness impact test may appear at any position on the cutter head, so the above observation method has a large possibility of misjudgment. The technical solution of the present application, on the one hand, can fully observe whether there are cracks in the milling cutter by rotating and adjusting the angle of the milling cutter, thereby further improving the detection accuracy; on the other hand, the first supporting roller and the second supporting roller can be close to or away from each other. In actual working conditions, after the inspection is completed, the first supporting roller and the second supporting roller move away from each other, causing the milling cutter to fall into the unloading track and unload the material, which is convenient for unloading;

[0037] 3. A sealing strip is slidably mounted on the opening end of the receiving box's chambers. Before collecting the qualified milling cutters, the second pusher activates to fully open the sealing strip, clearing all chamber openings. As the first pusher moves stepwise to collect the qualified milling cutters one by one, the sealing strip slides relative to the receiving box, closing each chamber opening one by one, thus conveniently sealing the receiving box containing the qualified milling cutters.

[0049] The present application is further described in detail below with reference to the accompanying drawings.

[0050] An embodiment of the present application discloses a detection device for detecting the stiffness of a micro milling cutter.

[0051] Reference Figure 1 and Figure 2A detection device for detecting the stiffness of a micro milling cutter comprises: a base 1, a placing block 2, a pushing cylinder 11, an impact cylinder 12, a protective box 3 and a feeding track 4, wherein the placing block 2 is fixedly mounted on the base 1, and a limiting channel 21 is formed through the placing block 2, and the limiting channel 21 has a head end 211 and a tail end 212; the pushing cylinder 11 is fixedly mounted on the base 1 at the tail end 212 of the limiting channel 21 along the axial direction of the limiting channel 21, and a pushing head 111 facing the limiting channel 21 is fixedly mounted on the piston rod of the pushing cylinder 11, and the diameter of the pushing head 111 is smaller than that of the limiting channel 21 The impact cylinder 12 is fixedly mounted on the base 1 at the head end 211 of the limiting channel 21 in a direction perpendicular to the axis of the limiting channel 21, and a striker 121 is fixedly mounted on the piston rod of the impact cylinder 12; the protective box 3 slides on the base 1 at the head end 211 of the limiting channel 21 in the direction of the axis of the limiting channel 21, and the protective box 3 has a first opening 31 and a second opening 32. The pushing cylinder 11 works to push the cutter head into the first opening 31, and the impact cylinder 12 works to extend the striker 121 into the second opening 32, so that the collision area between the striker 121 and the cutter head is located inside the protective box 3. The feed end of the blanking track 4 is located directly below the head end 211 of the limiting channel 21, and the protective box 3 can slide to avoid above the feed end of the blanking track 4. The pushing cylinder 11 works again to push the milling cutter out of the limiting channel 21 and drop it into the blanking track 4.

[0052] Reference Figure 1 and Figure 2 The top of the material block 2 has a guide opening 22, which communicates with the limiting channel 21. The guide opening 22 gradually narrows from the top of the material block 2 toward the limiting channel 21. The milling cutter falls into the limiting channel 21 through the guide opening 22. The pushing cylinder 11 performs an initial push, pushing the cutter head out of the first end 211 of the limiting channel 21, ready for the subsequent collision between the impact head 121 and the cutter head. It is worth noting that the diameter of the limiting channel 21 is adapted to the diameter of the milling cutter, effectively limiting the milling cutter.

[0053] Reference Figure 1 and Figure 2 The piston rod of the impact cylinder 12 is arranged horizontally along the axis perpendicular to the limiting channel 21. The impact head 121 is fixedly mounted on the piston rod of the impact cylinder 12. When the impact cylinder 12 is in operation, it can drive the impact head 121 to slide and fit the end surface of the material block 2 at the head end 211 of the limiting channel 21, so that the impact head 121 can perform a collision test on the cutter head of the milling cutter. For ease of understanding, the collision area between the impact head 121 at the head end 211 of the limiting channel 21 and the cutter head is defined as the collision space.

[0054] Reference Figure 1 and Figure 2A discharge port 13 connected to the feed end of the discharge track 4 is vertically penetrated on the base 1. The discharge port 13 is located on the base 1 at the head end 211 of the limiting channel 21. The feed end of the discharge track 4 is connected to the bottom of the discharge port 13. The milling cutter after inspection falls into the discharge track 4 through the discharge port 13 for collection and storage.

[0055] Reference Figure 1 and Figure 2 The protective box 3 and the detection module 5 are both slidably mounted on the base 1. The diameter of the first opening 31 of the protective box 3 is larger than the limit channel 21, and the diameter of the second opening 32 is larger than the impact head 121. The protective box 3 slides on the base 1 and has a protective state and an avoidance state. In the protective state, the protective box 3 slides to the outside of the head end 211 of the limit channel 21. At this time, the first opening 31 faces the limit channel 21, and the second opening 32 faces the impact head 121. The pushing cylinder 11 and the impact cylinder 12 work so that the impact head 121 and the cutter head of the milling cutter are collided in the collision space inside the protective box 3. In the avoidance state, the protective box 3 avoids above the feed end of the unloading track 4, and the protective box 3 is located on the side of the unloading port 13 away from the material placement block 2 to avoid the unloading process of the milling cutter.

[0056] Reference Figure 1 and Figure 2 , a detection module 5 for detecting cracks in the milling cutter is also slidably mounted on the base 1. The detection module 5 includes a sliding frame 51 slidably mounted on the base 1 and a detection camera 52. The detection camera 52 is fixedly mounted on the sliding frame 51 and can slide to just above the head end 211 of the limiting channel 21. Specifically, the base 1 has a first slide rail 14 parallel to the axial direction of the limiting channel 21, a second slide rail 15 perpendicular to the axis of the limiting channel 21, and a third slide rail 16 parallel to the axial direction of the limiting channel 21. The protective box 3 slides on the first slide rail 14, the detection module 5 slides on the second slide rail 15, and the second slide rail 15 is slidably mounted on the third slide rail 16. The cylinder for driving the sliding is not shown in the figure. When the protective box 3 is in the protective state, the detection module 5 slides to the side away from the discharge port 13 to avoid the movement trajectory of the protective box 3; when the protective box 3 is in the avoidance state, the detection module 5 slides to between the head end 211 of the limiting channel 21 and the discharge port 13, so that the detection camera 52 is located directly above the head end 211 of the limiting channel 21, and then the pushing cylinder 11 pushes the material again and pushes the milling cutter onto the detection module 5 for appearance inspection.

In actual operation, the first supporting roller 53 and the second supporting roller 54 are in a mutually abutting working state. In this working state, a supporting space 55 is formed above the first supporting roller 53 and the second supporting roller 54, facing the first end 211 of the limiting channel 21. At this time, the sliding frame 51 slides along the third slide rail 16 to the first end 211 of the limiting channel 21, allowing the cutter head of the milling cutter to enter the supporting space 55. After the impact test, the milling cutter is pushed by the pushing head 111 and is carried in the supporting space 55. The rotary motor 531 is activated to drive the first supporting roller 53 to rotate, and the milling cutter rotates about its own axis. Simultaneously, the inspection camera 52 is activated to perform a visual inspection of the milling cutter. It is worth mentioning that after the inspection is completed, the sliding frame 51 slides along the third slide rail 16 in the direction away from the limiting channel 21, so that the carrying space 55 is located directly above the discharge port 13, and then the rodless cylinder 532 works to drive the first carrying roller 53 to slide away from the second carrying roller 54, and the milling cutter falls into the discharge port 13 between the first carrying roller 53 and the second carrying roller 54. The detection light source also includes a light source module 56, which is fixedly mounted on the carrying plate 511 and thus indirectly fixedly mounted on the sliding frame 51, and the light source module 56 is arranged around the carrying space 55. The light source module 56 works to illuminate the carrying space 55 to facilitate the appearance inspection of the detection camera 52, which will not be described in detail here.

The rotating plate 431 is connected to the output shaft of the reversing motor 432. The reversing motor 432 works to drive the rotating plate 431 to close the defective unloading rail 41 or the good unloading rail 42. The switch 43 is used to guide the milling cutter to the good unloading rail 42 or the defective unloading rail 41. In actual working conditions, the detection device also includes a control board, and the detection camera 52 and the adjustment motor of the switch 43 are electrically connected to the control board. The detection camera 52 detects defective products to control the switch 43 to close the good product discharge rail 42, and the detection camera 52 detects good products to control the switch 43 to close the defective product discharge rail 41.

The receiving box 62 has multiple receiving cavities 621 parallel to the axis of the good product discharge rail 42. The receiving box 62 is slidably arranged in a direction perpendicular to the axis of the good product discharge rail 42. Specifically, the detection device also includes a supporting platform 6, which has an inclined supporting surface 61. The receiving box 62 and the good product discharge rail 42 are both arranged in contact with the supporting surface 61 so that the good product discharge rail 42 and the receiving box 62 have the same pitch tilt angle.

The piston rod of the first cylinder 641 is arranged parallel to the fourth slide rail 63, and the first pusher plate 642 is used to abut against the accommodating box 62. The first cylinder 641 of the first pusher 64 works step by step to push the accommodating box 62 so that the accommodating chambers 621 are aligned with the good product unloading rail 42 one by one to receive the good product milling cutter. The accommodating chamber 621 has a chamber opening 622 facing the good product unloading rail 42, and a silicone cushion pad 623 is fixedly installed on the end of the accommodating chamber 621 away from the chamber opening 622.

Specifically, the second pushing piece 66 includes a second cylinder 661 and a second pushing plate 662. The piston rod of the second cylinder 661 is arranged parallel to the fourth slide rail 63, and the second pushing plate 662 is used to abut against the sealing strip 65. The second pushing piece 66 is used to push the sealing strip 65 to avoid all the chamber openings 622 and abut against the stop block 67, thereby opening all the chamber openings 622 on the receiving box 62. The first pushing piece 64 works to make the receiving box 62 and the sealing strip 65 slide relative to each other to close the chamber openings 622 one by one.

[0063] Reference Figure 3 and Figure 4It is worth mentioning that the sealing strip 65 has a first limiting portion 651 and a second limiting portion 652.

The first limiting portion 651 is always limited and slidable between the two inner side walls opposite to each other at the opening of the container 62, and cannot slide out of the container 62. The second limiting portion 652 is provided with a convex engaging protrusion 653. Correspondingly, a concave engaging groove 625 is provided on the side wall of the container 62 facing the stop block 67. The second limiting portion 652 can slide to fit the side wall of the stop block 67, and the engaging protrusion 653 elastically deforms and snaps into the engaging groove 625. At this time, the sealing strip 65 simultaneously closes all chamber openings 622, thereby sealing the container 62. In the embodiment of the present application, after the user unlocks the locking protrusion 653 and the locking groove 625, the storage box 62 is slidably placed in the fourth slide rail 63, and the storage cavity 621 on the storage box 62 close to the stop block 67 is facing the good product unloading rail 42, and then the second pusher 66 works to push the sealing strip 65 to move to contact the stop plate and open all the chamber openings 622, and the first pusher 64 moves step by step to drive the storage cavity 621 to align with the good product unloading rail 42 one by one to receive the good milling cutters one by one. At the same time, the sealing strip 65 and the storage box 62 slide relative to each other to close the chamber openings 622 one by one.

[0064] The implementation principle of the detection device for detecting the stiffness of a micro-milling cutter in the embodiment of the present application is as follows: by setting up a protective box 3, an opening is reserved on the protective box 3 for the impact head 121 and the cutter head to enter, so that the collision area of ​​the cutter head of the micro-milling cutter is located inside the protective box 3. The milling cutter after the collision is rotated and multi-angled and detected by the detection module 5. Good products enter the good product discharge track 42 via the discharge track 4, and the good products slide one by one into the accommodating cavity 621 of the accommodating box 62. At the same time, the sealing strip 65 seals the cavity opening 622, thereby realizing the detection and collection of good products.
