Description

Technical Field

[0001] This invention belongs to the technical field of drill bit production equipment, specifically referring to a drill bit grinding machine loading device that intelligently senses deformation. Background Technology

[0002] A drill bit grinder is a specialized machine tool used for precision grinding of the cutting edges of drill bits. It uses a high-speed rotating grinding wheel to sharpen dull or damaged drill bits, restoring their geometric accuracy and cutting performance. This equipment typically features CNC or semi-automatic functions, precisely controlling parameters such as the drill bit's point angle, clearance angle, and chisel edge to ensure cutting edge symmetry and cutting efficiency. Widely used in machinery manufacturing, mold making, and other fields, it significantly extends drill bit lifespan and reduces tooling costs, making it a key piece of equipment for improving process quality and efficiency in metal processing.

[0003] Integrating an automatic feeding device into a drill bit grinding machine enables automated feeding and grinding of drill bits. After the drill bit completes multiple processes such as rough grinding, heat treatment, finish machining, and transfer, especially during heat treatment and transfer, the probability of the drill bit bending and deforming is relatively high due to thermal stress and mechanical external forces.

[0004] Currently, before entering the grinding process, drill bits must be inspected using specialized testing equipment, and only those that pass the inspection can be ground. While this offline inspection method can effectively detect defective products, it also increases production time, thereby affecting overall production efficiency. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide an intelligent deformation sensing feeder for drill grinding machines, so as to at least partially solve the problems mentioned in the background art.

[0006] The technical solution adopted by this invention is as follows: This invention proposes an intelligent deformation-sensing drill bit grinding machine loading device, comprising: A feeding track, with a feeding unit on one side for feeding materials onto the feeding track; A push rod is disposed inside the feeding track, and a drive mechanism is connected to the feeding track to drive the push rod to move along the length direction of the feeding track; The feeding track is connected to an inner tube at one end in the feeding direction. The inner tube has multiple slots at one end near the feeding track, forming multiple detection petals that are distributed circumferentially on the inner tube and can elastically deform radially. A sleeve is fitted around the outer side of the inner tube, and multiple pressure sensors corresponding to the detection petal are installed on the sleeve. The detection end of the pressure sensor is connected to the detection petal so that the deformation of the detection petal can be detected.

[0007] Furthermore, a material distribution track is provided at the end of the inner tube away from the feeding track. A flipping motor is connected to the feeding track, and the output end of the flipping motor is connected to the material distribution track, so that the flipping motor can drive the material distribution track to flip.

[0008] Furthermore, the inner diameter of the sleeve is larger than the outer diameter of the inner tube, so that a deformation gap is formed between the inner tube and the sleeve to allow the detection petal to deform.

[0009] Furthermore, a boss is provided on the outer side of the end of the inner tube away from the detection flap, and an external thread is provided on the boss. An internal thread corresponding to the external thread is provided on the inner wall of the sleeve, and the sleeve is connected to the boss by the thread.

[0010] Furthermore, a fixed frame is connected to the feeding track, and the sleeve is connected to the fixed frame.

[0011] Furthermore, the inner tube is provided with a guide slope at one end near the feeding track.

[0012] Furthermore, the feeding unit includes a lead screw slide and a feeding box. The feeding box has a discharge port at the bottom of one end near the feeding track, and the discharge port is arranged parallel to the length direction of the feeding track. The feeding box is connected to the output end of the lead screw slide, and the lead screw slide is configured to drive the feeding box closer to or away from the feeding track along the length direction perpendicular to the feeding track.

[0013] Furthermore, the bottom end of the discharge port is located above the feeding track.

[0014] Furthermore, the driving mechanism includes a lead screw, a drive motor, and a connecting frame. The lead screw is connected to the bottom of the feeding track, and the length direction of the lead screw is arranged parallel to the length direction of the feeding track. The drive motor is connected to the feeding track, and the output end of the drive motor is connected to one end of the lead screw. One end of the connecting frame is connected to the lead screw, and the other end of the connecting frame is connected to the push rod.

[0015] Furthermore, the end of the material distribution track away from the inner tube is provided with an extension track, which is connected to the feeding track via a connecting plate.

[0016] Beneficial effects: 1. By setting an inner tube on the feeding track, and having multiple circumferentially distributed detection petals on the inner tube, the drill bit passes through the inner tube during the pushing process. If the drill bit itself bends, it will exert a squeezing force on the detection petals, causing them to deform. The detection petals are detected by a pressure sensor. Based on the detected pressure value, it is determined whether the drill bit is bent and whether the bending degree meets the requirements. This realizes online detection during the drill bit feeding process, improves the continuity of drill bit production, and thus improves production efficiency.

[0017] 2. By setting up a material distribution track, the drill bit can be pushed into the material distribution track after passing through the inner tube. When the drill bit is detected as unqualified, the flip motor drives the material distribution track to flip, so that the groove of the material distribution track faces downward. At this time, the drill bit in the material distribution track falls out, realizing the online rejection of unqualified drill bits. Attached Figure Description

[0020] The accompanying drawings are provided to further understand the embodiments and form part of the specification. They are used together with the embodiments for explanation and do not constitute a limitation on the embodiments. Detailed Implementation

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0022] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0023] Combination Figure 1 As shown, this embodiment of the invention provides a smart deformation sensing feed device for a drill grinding machine, including a feed track 1, a feeding unit 2, a push rod 3, and a drive mechanism 4.

[0024] The feeding unit 2 is located on one side of the feeding track 1. The feeding unit 2 can feed the drill bits to be ground one by one into the feeding track 1.

[0025] The push rod 3 is set inside the feeding track 1, and the feeding track 1 is connected to a drive mechanism 4 that can drive the push rod 3 to move along the length direction of the feeding track 1. Under the drive of the drive mechanism 4, the push rod 3 can push the drill bit that is fed into the feeding track 1 toward the grinding equipment.

[0026] Thus, the feeding unit 2 supplies one drill bit into the feeding track 1 each time, and then retracts. After the feeding unit 2 finishes feeding, the drive mechanism 4 drives the push rod 3 to move. The push rod 3 pushes the drill bit in the feeding track 1 to move along the feeding track 1 until it is pushed into the grinding equipment. Then, the drive mechanism 4 drives the push rod 3 to retract back to its original position.

[0027] In a specific embodiment, the feeding unit 2 includes a lead screw slide 21 and a feeding box 22. The feeding box 22 has a discharge port 221 at the bottom of one end near the feeding track 1. The discharge port 221 is arranged parallel to the length direction of the feeding track 1. The feeding box 22 is connected to the output end of the lead screw slide 21. The lead screw slide 21 can drive the feeding box 22 to move, and the conveying direction of the lead screw slide 21 is perpendicular to the length direction of the feeding track 1, so that the lead screw slide 21 can drive the feeding box 22 to move closer to or away from the feeding track 1 along the length direction perpendicular to the feeding track 1.

[0028] It should be noted that the lowest point of the discharge port 221 is located above the feeding track 1, so that the discharge port 221 of the feeding box 22 can move to the top of the feeding track 1, and the drill bit in the feeding box 22 falls into the feeding track 1 from the discharge port 221 under the action of gravity.

[0029] The vertical distance between the lowest point of the discharge port 221 and the upper surface of the feeding track 1 is less than the diameter of the drill bit. The drill bit will not fall off when the discharge port 221 has not moved to the groove of the feeding track 1, thus playing a limiting role.

[0030] Thus, when no material is being supplied, the feeding box 22 is moved to the side of the discharge port 221 located in the groove of the feeding track 1, and the feeding track 1 is used to block the discharge port 221 to prevent the drill bit from falling. When material is being supplied, the feeding box 22 is moved to the side of the discharge port 221 located directly above the groove of the feeding track 1, and the drill bit in the feeding box 22 falls into the feeding track 1 from the discharge port 221 under the action of gravity.

[0031] It should be noted that the depth and width of the groove of the feeding track 1 are adapted to the diameter of the drill bit, so that when the discharge port 221 is located directly above the groove of the feeding track 1, only one drill bit can fall in.

[0032] Combination Figure 2 As shown, the drive mechanism 4 includes a lead screw 41, a drive motor 42, and a connecting frame 43. The lead screw 41 is connected to the bottom of the feeding track 1, and the length direction of the lead screw 41 is parallel to the length direction of the feeding track 1. The drive motor 42 is connected to the feeding track 1, and the output end of the drive motor 42 is connected to one end of the lead screw 41. The drive motor 42 can drive the lead screw 41 to rotate, and by adjusting the rotation direction of the drive motor 42, the lead screw 41 can rotate forward or backward.

[0033] One end of the connecting frame 43 is connected to the lead screw 41. As the lead screw 41 rotates, the connecting frame 43 can be pushed by the lead screw 41 and move along the length direction of the feeding track 1. By controlling the lead screw 41 to rotate forward or backward, the connecting frame 43 can reciprocate. The other end of the connecting frame 43 is connected to the push rod 3, so that the lead screw 41 can drive the push rod 3 to move along the length direction of the feeding track 1 through the connecting frame 43.

[0034] Thus, when it is necessary to push the drill bit in the feeding track 1 to the grinding equipment, the drive motor 42 drives the lead screw 41 to rotate, and the connecting frame 43, which is connected to the lead screw 41 at one end, drives the push rod 3 to move along the feeding track 1 until the push rod 3 pushes the drill bit to the grinding equipment. Then, the drive motor 42 drives the lead screw 41 to flip, so that the connecting frame 43 and the push rod 3 can be reset and ready for the next push.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, the feeding track 1 is connected to an inner tube 5 at one end in the feeding direction. When the push rod 3 pushes the drill bit toward the grinding equipment, it can pass through the inside of the inner tube 5. The inner tube 5 has multiple strip grooves 51 at one end near the feeding track 1, so that multiple circumferentially evenly distributed detection petals 52 that can elastically deform in the radial direction are formed on the inner tube 5. The detection petals 52 are located at one end of the inner tube 5 near the feeding track 1. The inner tube 5 corresponds to the groove of the feeding track 1, so that the drill bit in the groove of the feeding track 1 can be pushed into the inside of the inner tube 5.

[0036] The inner diameter of the inner tube 5 is matched with the diameter of the drill bit, so that the drill bit can slide normally through the inside of the inner tube 5, and the drill bit will not wobble radially inside the inner tube 5.

[0037] When the drill bit is pushed through the inner tube 5 by the push rod 3, if the drill bit itself bends, it will exert a radial compressive force on the inner tube 5.

[0038] A sleeve 53 is fitted on the outer side of the inner tube 5. Multiple pressure sensors 54, each corresponding to a detection petal 52, are installed on the sleeve 53. The detection end of the pressure sensor 54 is connected to the detection petal 52 so that the deformation of the detection petal 52 can be detected.

[0039] Thus, when the drill bit is pushed through the inner tube 5 by the push rod 3, the detection petal 52 on the inner tube 5 contacts the drill bit first. As the drill bit is continuously pushed into the inner tube 5, the drill bit slides in contact with the detection petal 52 along its own axis. If the drill bit itself bends, it will generate a squeezing force on the detection petal 52, causing the detection petal 52 to deform radially along the inner tube 5 and apply pressure to the pressure sensor 54 on the outside. The pressure sensor 54 detects the pressure value.

[0040] The greater the deformation of the detection valve 52, the greater the detection value of the pressure sensor 54, and correspondingly, the greater the bending amplitude of the drill bit. Therefore, when the detected pressure value exceeds the normal range, the drill bit is deemed unqualified.

[0041] It should be noted that the diameter of the push rod 3 is smaller than the inner diameter of the inner tube 5, and the connecting frame 43 is connected to the end of the push rod 3 away from the feeding direction. Therefore, when the push rod 3 pushes the drill bit, the push rod 3 can enter the inner tube 5 and push the drill bit completely through the inner tube 5, increasing the pushing distance of the push rod 3.

[0042] Combination Figure 4 As shown, a boss 55 is provided on the outer side of the end of the inner tube 5 away from the detection valve 52. An external thread 551 is provided on the boss 55. An internal thread 531 corresponding to the external thread 551 is provided on the inner wall of the sleeve 53. The sleeve 53 is connected to the boss 55 by the thread.

[0043] It should be noted that when the sleeve 53 is screwed onto the boss 55, the multiple pressure sensors 54 on the sleeve 53 correspond one-to-one with the multiple detection segments 52 (e.g., ...). Figure 3 (As shown).

[0044] Furthermore, a fixed frame 56 is connected to the feeding track 1, and the sleeve 53 is connected to the fixed frame 56. The fixed frame 56 provides overall support for the inner tube 5 and the sleeve 53.

[0045] Combination Figure 3 As shown, the inner tube 5 is provided with a guide slope 502 at one end near the feeding track 1. When the drill bit is pushed into the inner tube 5, the guide slope 502 can play a guiding role, so that the drill bit can be smoothly pushed into the interior of the inner tube 5.

[0046] Combination Figure 1 and Figure 2 As shown, the inner tube 5 is provided with a material distribution track 6 at the end away from the feeding track 1. After the drill bit passes through the inner tube 5, it can be pushed into the material distribution track 6. The feeding track 1 is connected to a flipping motor 61. The output end of the flipping motor 61 is connected to the material distribution track 6, so that the flipping motor 61 can drive the material distribution track 6 to flip.

[0047] When the drill bit passes through the inner tube 5 and is detected as unqualified, the flip motor 61 drives the material distribution track 6 to flip, so that the groove of the material distribution track 6 faces downward. At this time, the drill bit in the material distribution track 6 falls out, and the push rod 3 stops pushing the drill bit and resets. When the drill bit passes through the inner tube 5 and is detected as qualified, the material distribution track 6 does not flip, and the push rod 3 continues to push the drill bit until it is pushed to the grinding equipment.

[0048] Combination Figure 3 and Figure 5 As shown, the inner diameter of the sleeve 53 is larger than the outer diameter of the inner tube 5, so that a deformation gap 501 is formed between the inner tube 5 and the sleeve 53. The deformation gap 501 provides sufficient space for the elastic deformation of the detection petal 52, thereby increasing the detection range of the drill bit bending amplitude.

[0049] Combination Figure 1 and Figure 2 As shown, the end of the material distribution track 6 away from the inner tube 5 is provided with an extension track 7. The extension track 7 is connected to the feeding track 1 through a connecting plate 8. The extension track 7 extends the support distance for the drill bit, so that the drill bit can be accurately pushed into the grinding equipment.

[0050] It should be noted that the length of the push rod 3 is greater than the sum of the lengths of the inner tube 5, the material distribution track 6, and the extension track 7, so that the push rod 3 can pass through the inner tube 5 and push the drill bit sequentially and completely through the material distribution track 6 and the extension track 7, and send it into the grinding equipment.

[0051] The working principle of this invention is as follows: During feeding, the feeding box 22 is moved to the position of the discharge port 221 directly above the groove of the feeding track 1. The drill bit in the feeding box 22 falls into the feeding track 1 from the discharge port 221 under the action of gravity. After feeding is completed, the feeding box 22 is moved to the side of the discharge port 221 located in the groove of the feeding track 1. The feeding track 1 is used to block the discharge port 221 to prevent the drill bit from falling. Then, the drive motor 42 drives the lead screw 41 to rotate. The connecting frame 43, which is connected to the lead screw 41 at one end, drives the push rod 3 to move along the feeding track 1. The push rod 3 pushes the drill bit toward the grinding equipment.

[0052] When the drill bit passes through the inner tube 5, the detection petal 52 on the inner tube 5 contacts the drill bit first. As the drill bit is continuously pushed into the inner tube 5, the drill bit slides in contact with the detection petal 52 along its own axis. If the drill bit itself bends, it will generate a squeezing force on the detection petal 52, causing the detection petal 52 to deform radially along the inner tube 5 and apply pressure to the pressure sensor 54 on the outside. The pressure sensor 54 detects the pressure value.

[0053] The greater the deformation of the detection valve 52, the greater the detection value of the pressure sensor 54, and correspondingly, the greater the bending amplitude of the drill bit. Therefore, when the detected pressure value exceeds the normal range, the drill bit is deemed unqualified, and vice versa.

[0054] After the drill bit passes through the inner tube 5, it can be pushed into the material distribution track 6. When the drill bit is detected as unqualified, the flip motor 61 drives the material distribution track 6 to flip, so that the groove of the material distribution track 6 faces downward. At this time, the drill bit in the material distribution track 6 falls out, and the push rod 3 stops pushing the drill bit and slides back to its original position. When the drill bit passes through the inner tube 5 and is detected as qualified, the material distribution track 6 does not flip, and the push rod 3 continues to push the drill bit until it is pushed to the grinding equipment. Then the push rod 3 slides back to its original position.

[0055] In summary, by setting an inner tube 5 at one end of the feeding track 1 in the feeding direction, and having multiple circumferentially distributed detection petals 52 on the inner tube 5, the drill bit passes through the inner tube 5 during the pushing process. If the drill bit itself bends, it will exert a squeezing force on the detection petals 52, causing the detection petals 52 to deform. The detection petals 52 are detected by a pressure sensor 54. Based on the detected pressure value, it is determined whether the drill bit is bent and whether the bending degree meets the requirements. This realizes online detection during the drill bit feeding process, improves the continuity of drill bit production, and thus improves production efficiency.

[0056] By setting up the material distribution track 6, the drill bit can be pushed into the material distribution track 6 after passing through the inner tube 5. When the drill bit is detected as unqualified, the flip motor 61 drives the material distribution track 6 to flip, so that the groove of the material distribution track 6 faces downward. At this time, the drill bit in the material distribution track 6 falls out, realizing the online rejection of unqualified drill bits.

[0058] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
