Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, specifically to a feeding component and an intelligent grinding machine. Background Technology

[0002] In the manufacturing process of disc-shaped or ring-shaped parts, the end faces of these parts typically need to be ground. However, existing grinding machines usually require workers to place the parts to be ground onto the grinding table, and then manually remove them after grinding. Therefore, workers need to be constantly present at the grinding machine during the grinding process, which not only increases the labor intensity of the workers but also leads to higher labor costs. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a feeding component and an intelligent grinding machine to reduce the labor intensity of workers and reduce labor costs.

[0004] To achieve the above objectives, in one aspect, the present invention provides a feeding assembly, comprising:

[0005] frame;

[0006] The slide is inclinedly mounted on the frame and fixedly connected to the frame. Limiting plates are provided on both sides of the slide, and the distance between the two limiting plates is adapted to the diameter of the part to be processed.

[0007] An inclined material carrier plate is positioned at the lowest point of the slide rail. A stop block is provided at its first end, which is hinged to the frame. The second end extends towards the highest point of the slide rail and can reciprocate around its own hinge center line at a first working position A and a second working position A. When the material carrier plate is in the first working position A, the working surface of the material carrier plate is flush with the working surface of the slide rail. When the material carrier plate is in the second working position A, the working surface of the material carrier plate remains horizontal.

[0008] A first torsion spring is disposed at the hinge center of the material carrier plate, with its two ends connected to the material carrier plate and the frame respectively, and in its natural state, it has a tendency to move the material carrier plate from the second working position A to the first working position A;

[0009] A material distribution mechanism, located in the middle of the slide rail, is used to allow the parts to be processed to slide one by one onto the carrier plate in an orderly manner; and

[0010] A locking mechanism is provided on the frame and / or the material carrier plate, which is used to lock the material carrier plate in the first working position A and release the lock on the material carrier plate after the workpiece to be processed abuts against the stop block.

[0011] Furthermore, the material dispensing mechanism includes:

[0012] The first mounting bracket is hinged to the frame and can swing back and forth between a first working position B and a second working position B about its own hinge center line.

[0013] Two first material distribution rods are arranged between the two limiting plates. The two first material distribution rods are arranged at intervals along the width direction of the slide and are respectively located on both sides of the vertical plane of the slide. The bottom ends of the two first material distribution rods are connected to the first mounting frame and the top ends extend freely.

[0014] Two second material distribution rods are disposed between the two limiting plates. These two second material distribution rods are spaced apart along the width of the slide rail and located on either side of the vertical plane of the slide rail. The top ends of the two second material distribution rods are connected to the first mounting bracket, and their bottom ends extend freely. The two second material distribution rods are located below the two first material distribution rods.

[0015] A first drive structure is disposed on the frame and is used to drive the first mounting bracket to reciprocate between the first working position B and the second working position B.

[0016] Specifically, when the first mounting bracket is in the first working position B, the top end of the first material distribution rod retracts into the working surface of the slide, and the distance between the bottom end of the second material distribution rod and the working surface of the slide is less than the thickness of the part to be processed; when the first mounting bracket is in the second working position B, the top end of the first material distribution rod extends beyond the working surface of the slide, and the distance between the bottom end of the second material distribution rod and the working surface of the slide is greater than or equal to the thickness of the part to be processed.

[0017] Let the distance between the two first dividing rods be L1, the distance between the two second dividing rods be L2, and the radius of the part to be processed be R. Then the following relationship holds: 0 < L1 < 2R, 0 < L2 < 2R. When the first mounting frame is in the second working position, the projection of the top of the first dividing rod on the working surface of the slide is within the area enclosed by the two circumscribed circles and the inner sides of the two limiting plates. The two circumscribed circles are within the working surface of the slide. The centers of the two circumscribed circles are on the perpendicular bisector of the line connecting the two second dividing rods, and the lower circumscribed circle is tangent to the two second dividing rods. The radius of the two circumscribed circles is R.

[0018] Furthermore, the two limiting plates can move closer to or further away from each other along the width direction of the slide;

[0019] The two first material distribution rods are slidably connected to the first mounting frame, and the two first material distribution rods can move closer to or further away from each other along the width direction of the slide rail;

[0020] The two second material distribution rods are slidably connected to the first mounting frame, and the two second material distribution rods can move closer to or further away from each other along the width direction of the slide rail;

[0021] The feeding assembly also includes:

[0022] The second driving structure is used to drive the two limiting plates to move closer or further apart from each other.

[0023] A third drive structure is used to drive the two first dispensing rods to move closer or further apart; and

[0024] The fourth drive structure is used to drive the two second dispensing rods to move closer or further apart from each other.

[0025] Furthermore, the second material distribution rod is a telescopic rod structure with adjustable length.

[0026] Furthermore, the first driving structure includes:

[0027] A cam, disposed on one side of the first mounting bracket and rotatably connected to the frame, its outer peripheral surface abutting against the first mounting bracket; and

[0028] A first motor for driving the cam to rotate about a preset angle α is fixedly mounted on the frame, where α = 180°.

[0029] Furthermore, the first drive structure also includes a torsion spring, which is disposed at the hinge center of the first mounting bracket. The two ends of the torsion spring are respectively connected to the first mounting bracket and the frame, and in its natural state, the torsion spring has a tendency to keep the first mounting bracket in contact with the cam.

[0030] Furthermore, the first driving structure also includes a position detection unit, which is used to detect the position of the material plate and transmit the detected position information of the material plate to the controller. When the position detection unit detects that the material plate moves from the first working position A to the second working position A or from the second working position A to the first working position A, the controller controls the first motor to drive the cam to rotate by a preset angle α.

[0031] Furthermore, the position detection unit includes:

[0032] The emitting end of the photoelectric through-beam sensor is disposed at the second end of the carrier plate; and

[0033] The receiving end of the photoelectric through-beam sensor is fixedly mounted on the frame. When the material carrier plate is in the first working position A, the transmitting end of the photoelectric through-beam sensor corresponds to one of the receiving ends of the two photoelectric through-beam sensors. When the material carrier plate is in the second working position A, the transmitting end of the photoelectric through-beam sensor corresponds to the other of the receiving ends of the two photoelectric through-beam sensors.

[0034] Furthermore, the locking mechanism includes:

[0035] A locking socket is provided on the frame;

[0036] A locking pin is disposed on one side of the material carrier plate and is slidably connected to the material carrier plate. It can reciprocate linearly between a first working position C and a second working position C in a direction close to or away from the locking hole. When the locking pin is in the first working position C, the locking pin extends beyond the side wall of the material stop block. When the locking pin is in the second working position C, the locking pin retracts into the side wall of the material stop block.

[0037] The first elastic element has its two ends connected to the locking pin and the stop block respectively, and in its natural state, it has a tendency to move the locking pin toward the locking hole.

[0038] The first slider has a first end that is slidably disposed with the stop block, and a second end that extends toward the second end of the carrier plate and extends beyond the side wall of the stop block, and can slide along the width direction of the stop block.

[0039] A pull cord, the two ends of which are respectively connected to the first slider and the locking pin; and

[0040] A baffle plate, which is fixedly connected to the frame, is used to block the locking pin inside the side wall of the baffle block during the movement of the material carrier plate from the second working position A to the first working position A.

[0041] On another front, the present invention also provides an intelligent grinding machine, including a body, a worktable, a grinding component, a lifting component, and a drive component disposed on the body, wherein the lifting component drives the grinding component to perform reciprocating linear motion up and down, and the drive component drives the worktable to move along the X-axis and / or Y-axis on the body, characterized in that: it further includes:

[0042] The feeding assembly described in any one of the above; and

[0043] A gripping component is used to transport the parts to be processed on the carrier plate to the worktable.

[0044] The beneficial effects of this invention are:

[0045] The feeding component and intelligent grinding machine provided by this invention achieve automatic feeding by setting up the feeding component, thereby reducing the labor intensity and labor costs of workers. Attached Figure Description

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly defined.

[0067] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0069] like Figure 1-11 As shown, the present invention provides a feeding assembly, including a frame 11, a slide rail 12, a material carrier plate 13, a first torsion spring (not shown in the figure), a material distribution mechanism 14, and a locking mechanism 15.

[0070] The slide rail 12 is inclinedly mounted on the frame 11 and fixedly connected to the frame 11. Limiting plates 16 are provided on both sides of the slide rail 12, and the distance between the two limiting plates 16 is adapted to the diameter of the part to be processed. The loading plate 13 is inclinedly mounted and located at the lowest point of the slide rail 12. A stop block 131 is provided at the first end of the loading plate 13. The first end of the loading plate 13 is hinged to the frame 11, and the second end extends towards the highest point of the slide rail 12. The second end of the loading plate 13 can swing back and forth around its own hinge center line in the first working position A and the second working position A. When the loading plate 13 is in the first working position A, the working surface of the loading plate 13 is flush with the working surface of the slide rail 12. When the loading plate 13 is in the second working position A, the working surface of the loading plate 13 remains horizontal.

[0071] The first torsion spring is installed at the hinge center of the carrier plate 13. Both ends of the first torsion spring are connected to the carrier plate 13 and the frame 11, respectively. In its natural state, it tends to move the carrier plate 13 from the second working position A to the first working position A. Specifically, initially, under the action of the first torsion spring, the carrier plate 13 is held in the first working position. After the workpiece slides onto the carrier plate 13 along the slide rail 12, the carrier plate 13 rotates from the first working position A to the second working position A under the force of gravity of the workpiece. The material distribution mechanism 14 is located in the middle of the slide rail 12, and is used to allow the workpieces to slide onto the carrier plate 13 one by one in an orderly manner. The locking mechanism 15 is installed on the frame 11 and / or the material plate 13. It is used to lock the material plate 13 in the first working position A and release the lock on the material plate 13 after the workpiece to be processed comes into contact with the stop block 131. That is, after the workpiece to be processed hits the stop block 131, the locking mechanism releases the lock on the material plate 13, thereby preventing the material plate 13 from rotating before the workpiece to be processed slides to the lowest point of the material plate 13. At the same time, the locking mechanism 15 will only release the lock on the material plate 13 when the workpiece to be processed moves to the point of contact with the stop block 131, thereby achieving the purpose of positioning the workpiece to be processed, so as to facilitate the gripping component to grip the workpiece to be processed.

[0072] In initial use, the locking mechanism 15 locks the carrier plate 13 in the first working position A. The workpiece to be processed, coming from the feed end of the slide 12, slides onto the carrier plate 13 under the influence of gravity and collides with the stop block 131. The locking mechanism 15 releases the lock on the carrier plate 13, and under the influence of the workpiece's gravity, the carrier plate 13 rotates from the first working position A to the second working position A, causing the workpiece to rotate to a horizontal position, thus facilitating the gripping assembly to grip the workpiece.

[0073] After the workpiece is removed, the material carrier plate 13 rotates from the second working position A to the first working position A under the action of the first torsion spring, and the locking mechanism 15 locks the material carrier plate 13 in the first working position A under the action of the locking mechanism 15.

[0074] In one embodiment, the material distribution mechanism 14 includes a first mounting frame 141, a first material distribution rod 142, a second material distribution rod 143, and a first drive structure.

[0075] The first mounting bracket 141 is hinged to the frame 11 and can reciprocate between the first working position B and the second working position B around its own hinge center line. There are two first distributing rods 142, which are positioned between the two limiting plates 16 and spaced apart along the width of the slide rail 12, respectively located on both sides of the vertical plane of the slide rail 12. Preferably, the two first distributing rods are symmetrically arranged on both sides of the vertical plane of the slide rail 12. The bottom ends of the two first distributing rods 142 are connected to the first mounting bracket 141, and their top ends extend freely.

[0076] There are two second material distribution rods 143, which are arranged between the two limiting plates 16. The two second material distribution rods 143 are spaced apart along the width direction of the slide rail 12 and are located on both sides of the vertical plane of the slide rail 12. Preferably, the two second material distribution rods 143 are symmetrically arranged on both sides of the vertical plane of the slide rail 12. The top ends of the two second material distribution rods 143 are connected to the first mounting bracket 141, and the bottom ends extend freely. The two second material distribution rods 143 are located below the two first material distribution rods 142.

[0077] The first drive structure is mounted on the frame 11 and is used to drive the first mounting bracket 141 to reciprocate between the first working position B and the second working position B. When the first mounting bracket 141 is in the first working position B, the top end of the first dividing rod 142 retracts into the working surface of the slide rail 12, and the distance between the bottom end of the second dividing rod 143 and the working surface of the slide rail 12 is less than the thickness of the part to be processed. Since the top end of the first dividing rod 142 is retracted below the working surface of the slide rail 12, the part to be processed can pass over the first dividing rod 142 along the slide rail 12. However, because the distance between the bottom end of the second dividing rod 143 and the working surface of the slide rail 12 is less than the thickness of the part to be processed, the part to be processed cannot pass through the gap between the second dividing rod 143 and the slide rail 12 along the slide rail 12.

[0078] When the first mounting bracket 141 is in the second working position B, the top end of the first dividing rod 142 extends beyond the working surface of the slide rail 12, and the distance between the bottom end of the second dividing rod 143 and the working surface of the slide rail 12 is greater than or equal to the thickness of the part to be processed. Since the top end of the first dividing rod 142 extends beyond the working surface of the slide rail 12, the part to be processed cannot pass over the first dividing rod 142 along the slide rail 12 under the action of the first dividing rod 142. However, since the distance between the bottom end of the second dividing rod 143 and the working surface of the slide rail 12 is greater than or equal to the thickness of the part to be processed, the part to be processed can pass through the gap between the second dividing rod 143 and the slide rail 12 along the slide rail 12.

[0079] Let L1 be the distance between the two first dividing rods 142, L2 be the distance between the two second dividing rods 143, and R be the radius of the part to be processed. Then the following relationships hold: 0 < L1 < 2R, 0 < L2 < 2R. Since the distance L1 between the two first dividing rods 142 satisfies the relationship 0 < L1 < 2R, the part to be processed cannot pass between the two first dividing rods 142. Therefore, when the top of the first dividing rod 142 extends beyond the working surface of the slide rail 12, the part to be processed cannot pass between the two first dividing rods 142. Similarly, since the distance L2 between the two second dividing rods 143 satisfies the relationship 0 < L2 < 2R, the part to be processed cannot pass between the two second dividing rods 143. Therefore, when the distance between the bottom of the second dividing rod 143 and the working surface of the slide rail 12 is less than the thickness of the part to be processed, the part to be processed cannot pass between the two second dividing rods 143.

[0080] like Figure 11 As shown, when the first mounting bracket 141 is in the second working position B, the projection of the top end of the first dividing rod 142 onto the working surface of the slide rail 12 lies within the area enclosed by the two circumscribed circles and the inner sides of the two limiting plates 16. The two circumscribed circles have the following characteristics: First, they lie within the working surface of the slide rail 12; second, their centers lie on the perpendicular bisector of the line connecting the two second dividing rods 143, and the lower circumscribed circle is tangent to the two second dividing rods 143; third, their radii are R. That is, there can always be only one part to be processed between the two first dividing rods 142 and the two second dividing rods 143.

[0081] In use, under the action of the first drive structure, the first mounting bracket 141 reciprocates between the first working position B and the second working position B. When the first mounting bracket 141 is in the first working position B, since the top end of the first dividing rod 142 retracts into the working surface of the slide rail 12, the part to be processed can pass over the first dividing rod 142 along the slide rail 12. However, since the distance between the bottom end of the second dividing rod 143 and the working surface of the slide rail 12 is less than the thickness of the part to be processed, the part to be processed cannot pass through the gap between the second dividing rod 143 and the slide rail 12. Therefore, when the part to be processed slides to the point of contact with the second dividing rod 143, it cannot continue to slide downwards along the slide rail 12.

[0082] When the first mounting bracket 141 swings to the second working position B, the top end of the first dividing rod 142 extends beyond the working surface of the slide rail 12. Therefore, under the action of the first dividing rod 142, the workpiece to be processed cannot pass above the first dividing rod 142 along the slide rail 12. That is, when the workpiece to be processed below the first dividing rod 142 slides to a point of contact with the first dividing rod 142, it cannot continue to slide downwards along the slide rail 12. However, since the distance between the bottom end of the second dividing rod 143 and the working surface of the slide rail 12 is greater than or equal to the thickness of the workpiece to be processed, the workpiece to be processed located between the first dividing rod 142 and the second dividing rod 143 can pass through the gap between the second dividing rod 143 and the slide rail 12. Since there is only one part to be processed between the first dividing rod 142 and the second dividing rod 143, when the first mounting frame 141 swings to the second working position B, only one part to be processed slides onto the material carrier plate 13 via the second dividing rod 143, thereby achieving the purpose of material division.

[0083] The material distribution mechanism 14 of this structure is simple in structure and reasonable in design.

[0084] In one embodiment, the two limiting plates 16 can move closer to or further away from each other along the width direction of the slide rail 12. Specifically, the limiting plates 16 are slidably connected to the frame 11. By changing the distance between the two limiting plates 16, parts with different outer diameters can be conveyed along the slide rail. The two first dividing rods 142 are slidably connected to the first mounting frame 141, and the two first dividing rods 142 can move closer to or further away from each other along the width direction of the slide rail 12. The two second dividing rods 143 are slidably connected to the first mounting frame 141, and the two second dividing rods 143 can move closer to or further away from each other along the width direction of the slide rail 12. By changing the distance between the two first dividing rods 142 and the two second dividing rods 143, parts with different outer diameters can be divided.

[0085] The feeding assembly also includes a second drive structure, a third drive structure, and a fourth drive structure.

[0086] The second driving structure is used to drive the two limiting plates 16 to move closer or further apart. Specifically, the second driving structure includes a first driving screw 17, which is rotatably connected to the frame 11. The first driving screw 17 has two threaded segments with the same pitch but opposite helical directions. The two limiting plates 16 are threadedly connected to the first driving screw 17 through the two threaded segments. In use, by rotating the first driving screw 17, the two limiting plates 16 are moved closer or further apart.

[0087] The third drive structure is used to drive the two first dispensing rods 142 to move closer or further apart. Specifically, the third drive includes a second drive screw 148, which is rotatably connected to the mounting bracket. The second drive screw 148 has two threaded sections with the same pitch but opposite helical directions. The two first dispensing rods 142 are threadedly connected to the second drive screw 148 through the two threaded sections. In use, rotating the second drive screw 148 achieves the purpose of moving the two first dispensing rods closer or further apart.

[0088] The fourth drive structure is used to drive the two second dispensing rods 143 to move closer or further apart. Specifically, the fourth drive structure includes a third drive screw 149, which is rotatably connected to the mounting bracket. The third drive screw 149 has two threaded sections with the same pitch but opposite helical directions. The two second dispensing rods 143 are threadedly connected to the third drive screw 149 through the two threaded sections. In use, rotating the third drive screw 149 achieves the purpose of moving the two second dispensing rods closer or further apart.

[0089] This powder structure allows for the application of powder to parts with different outer diameters, thereby improving adaptability.

[0090] In one embodiment, the second dispensing rod 143 is a telescopic rod structure with adjustable length. By changing the length of the second dispensing rod 143, the distance between the second dispensing rod 143 and the working surface of the slide 12 can be changed, thereby enabling the dispensing of powder for parts of different thicknesses.

[0091] In one embodiment, the first drive structure includes a cam 144 and a first motor 145.

[0092] The cam 144 is mounted on one side of the first mounting bracket 141 and rotatably connected to the frame 11, with its outer circumferential surface abutting against the first mounting bracket 141. The first motor 145 is fixedly mounted on the frame 11 and drives the cam 144 to rotate around a preset angle α, where α = 180°. Specifically, the power output shaft of the first motor 145 is drive-connected to the power input end of the cam 144, for example, the power input shaft of the first motor 145 is fixedly connected to the cam 144, or the power output shaft of the first motor 145 is drive-connected to the power input end of the cam 144 via a gear structure or a conveyor belt structure. Preferably, the first drive structure further includes a torsion spring, which is located at the hinge center of the first mounting bracket 141. The two ends of the torsion spring are respectively connected to the first mounting bracket 141 and the frame 11, and in its natural state, the torsion spring tends to keep the first mounting bracket 141 and the cam 144 in contact.

[0093] In use, the first motor 145 drives the cam 144 to rotate, thereby driving the first mounting bracket 141 to swing back and forth between the first working position B and the second working position B.

[0094] The first driving structure of this structure is simple and reasonably designed.

[0095] In one embodiment, the first driving structure further includes a position detection unit, which detects the position of the carrier plate 13 and transmits the detected position information of the carrier plate 13 to the controller. Specifically, when the position detection unit detects that the carrier plate 13 has moved from the first working position A to the second working position A or from the second working position A to the first working position A, the controller controls the first motor 145 to drive the cam 144 to rotate by a preset angle α. When the position detection unit detects that the carrier plate 13 has moved from the first working position A to the second working position A, the controller controls the first motor 145 to drive the cam 144 to rotate by a preset angle α. When the position detection unit detects that the carrier plate 13 has moved from the second working position A to the first working position A, the controller controls the first motor 145 to drive the cam 144 to rotate by the preset angle α again, thereby achieving the purpose of real-time conveying of the workpiece to be processed onto the carrier plate 13.

[0096] In one embodiment, the position detection unit includes a photoelectric through-beam sensor.

[0097] The transmitting end 146 of the photoelectric through-beam sensor is fixedly installed at the second end of the carrier plate 13. There are two receiving ends 147 of the photoelectric through-beam sensor, which are fixedly mounted on the frame 11. When the carrier plate 13 is in the first working position A, the transmitting end 146 of the photoelectric through-beam sensor corresponds to one of the two receiving ends 147. When the carrier plate 13 is in the second working position A, the transmitting end 146 of the photoelectric through-beam sensor corresponds to the other of the two receiving ends 147.

[0098] Specifically, when the transmitting end 146 of the through-beam photoelectric sensor corresponds to one of the receiving ends 147, it means that the material carrier plate 13 moves from the second working position A to the first working position A. When the transmitting end 146 of the through-beam photoelectric sensor corresponds to the other receiving end 147, it means that the material carrier plate 13 moves from the first working position A to the second working position A.

[0099] The position detection unit of this structure is simple in structure and reasonable in design.

[0100] In one embodiment, the locking mechanism 15 includes a locking socket 151, a locking pin 152, a first elastic element 153, a first slider 154, a pull cord 155, and a blocking plate 156.

[0101] A locking hole 151 is provided on the frame 11. A locking pin 152 is provided on one side of the material carrier plate 13 and is slidably connected to the material carrier plate 13. Specifically, the material carrier plate 13 has a mounting hole, and the locking pin 152 is slidably inserted into the mounting hole. The locking pin 152 can reciprocate linearly between a first working position C and a second working position C in a direction close to or away from the locking hole 151. When the locking pin 152 is in the first working position C, the locking pin 152 extends beyond the side wall of the stop block 131, thereby inserting into the locking hole 151 to lock the material carrier plate 13. When the locking pin 152 is in the second working position C, the locking pin 152 retracts into the side wall of the stop block 131, thereby pulling out of the locking hole 151 to release the locking of the material carrier plate 13.

[0102] The two ends of the first elastic element 153 are connected to the locking pin 152 and the stop block 131 respectively. Specifically, the first elastic element 153 is a spring. The first elastic element 153 is installed in the mounting hole, and in its natural state, the first elastic element 153 has a tendency to move the locking pin 152 toward the locking hole 151.

[0103] The first slider 154 is installed between the two limiting plates 16 to facilitate the movement of the workpiece. The first end of the first slider 154 is slidably disposed with the stop block 131, and the second end extends towards the second end of the carrier plate 13 and beyond the side wall of the stop block 131, allowing it to slide along the width of the stop block 131. The two ends of the pull rope 155 are respectively connected to the first slider 154 and the locking pin 152. Specifically, the pull rope 155 passes around the guide wheel and is fixedly connected to the first slider 154 and the locking pin 152.

[0104] The baffle plate 156 is fixedly connected to the frame 11. It is used to block the locking pin 152 within the side wall of the stop block 131 during the movement of the material carrier plate 13 from the second working position A to the first working position A. In use, after the workpiece is removed from the material carrier plate 13, the locking pin 152 will move from the second working position C to the first working position C under the action of the first elastic element 153, thus affecting the movement of the material carrier plate 13. By setting the baffle plate 156, during the movement of the material carrier plate 13 from the second working position A to the first working position A after the workpiece is removed from the material carrier plate 13, the locking pin 152 cannot move from the second working position C to the first working position C under the elastic force of the first elastic element 153, thus achieving the purpose of not affecting the movement of the material carrier plate 13.

[0105] In use, when the workpiece to be processed slides along the slide rail 12 onto the carrier plate 13, the workpiece will come into contact with the first slider 154 to push the first slider 154 to move. This causes the first slider 154 to drive the locking pin 152 to move from the first working position C to the second working position C via the pull rope 155, so as to achieve the purpose of pulling the locking pin 152 out of the locking hole 151, thereby achieving the purpose of unlocking the locking structure from locking the carrier plate 13. Then, under the action of the gravity of the workpiece to be processed, the carrier plate 13 rotates from the first working position A to the second working position A.

[0106] After the workpiece is removed from the carrier plate 13, the carrier plate 13 moves from the second working position A to the first working position A under the action of the torsion spring. During this process, under the action of the blocking plate 156, the blocking plate 156 blocks the locking pin 152 at the second working position C, so that the locking pin 152 cannot move to the first working position C.

[0107] When the material carrier plate 13 moves to the first working position A, the locking pin 152 corresponds to the locking hole 151. Under the action of the elastic force of the first elastic member 153, the locking pin 152 moves from the second working position C to the first working position C and is inserted into the locking hole 151, thereby achieving the purpose of locking the material carrier plate 13 to the first working position A.

[0108] The locking mechanism 15 of this structure is simple in structure and reasonable in design. It uses the material carrier plate 13 to push the first slider 154 to move, thereby achieving the purpose of unlocking the material carrier plate 13. It is convenient and reliable to operate.

[0109] Preferably, the locking mechanism further includes a second elastic element 157, which is a spring. Both ends of the second elastic element 157 are connected to the second slider 154 and the material carrier plate 13, respectively. In its natural state, the second elastic element 157 tends to move the second slider 154 away from the feed end of the slide rail 12, and the elastic force of the second elastic element 157 is less than the elastic force of the first elastic element 153. Under the action of the elastic forces of the first elastic element 153 and the second elastic element 157, the pull rope 155 is always kept taut.

[0110] like Figure 12-13 As shown, the present invention also provides an intelligent grinding machine, including a body 2, a worktable 3, a grinding component 4, a lifting component, and a driving component mounted on the body 2. The lifting component drives the grinding component 4 to perform reciprocating linear motion up and down, and the driving component drives the worktable 3 to move along the X-axis and / or Y-axis on the body 2. These are all existing technologies and will not be described in detail here.

[0111] The aforementioned intelligent grinding machine also includes the aforementioned feeding component 1 and gripping component 5.

[0112] The gripping component 5 is used to transport the parts to be processed on the carrier plate 13 to the worktable.

[0113] In use, the gripping component 5 moves the workpiece to be processed on the material carrier plate 13 to the worktable, and then the grinding component 4 grinds it. Specifically, firstly, the lifting component drives the grinding component 4 to descend, and then the driving component drives the worktable to move. Under the action of the rotating grinding wheel, the workpiece to be processed is ground.

[0114] In one embodiment, the gripping component 5 includes a second slider 51, a fifth drive structure, a second mounting bracket 53, an electromagnet 54, and a sixth drive structure.

[0115] The second slider 51 can reciprocate linearly between the first working position D and the second working position D along the line connecting the material carrier plate 13 and the worktable. The fifth drive structure is used to drive the second slider 51 to reciprocate linearly between the first working position D and the second working position D. Specifically, the fifth drive structure includes a first electric push rod 52, and the power output shaft of the first electric push rod 52 is fixedly connected to the second sliding push rod.

[0116] The second mounting bracket 53 has a longitudinal support arm and a transverse support arm. The bottom end of the longitudinal support arm is fixedly connected to the second slider 51, and the first end of the transverse support arm is fixedly connected to the top end of the longitudinal support arm. An electromagnet 54 is disposed at the second end of the transverse support arm and can reciprocate linearly between the first working position E and the second working position E along the longitudinal direction. A sixth drive structure is disposed at the second end of the transverse support arm and is used to drive the electromagnet 54 to reciprocate linearly between the first working position E and the second working position E. Specifically, the sixth drive structure includes a second electric push rod 55, which is fixedly mounted at the second end of the transverse support arm, and the electromagnet 54 is fixedly mounted on the power output shaft of the second electric push rod 55.

[0117] In use, under the action of the fifth drive structure, the fifth drive structure drives the second slider 51 to reciprocate linearly between the first working position D and the second working position D. Under the action of the sixth drive structure, the sixth drive structure drives the electromagnet 54 to reciprocate linearly between the first working position E and the second working position E. Under the action of the electromagnet 54, the purpose of picking up the workpiece to be processed on the carrier plate 13 and moving it to the worktable is achieved.
