Description

Technical Field

[0001] The present invention relates to the technical field of pick - tooth feeding, and specifically to an automated single - row pick - tooth feeding device. Background Art

[0002] A pick - tooth generally consists of a tooth head, a tooth body, a shoulder ring provided on the outer side of the middle part of the tooth body, and a neck section provided at the bottom of the tooth body. When manufacturing pick - teeth, related steps such as cutting and forming, welding, heat treatment, finishing and grinding, quality inspection, and surface treatment are required in sequence. Among them, during the stages of heat treatment, quality inspection, and surface treatment of semi - finished pick - teeth, the semi - finished pick - teeth need to be conveyed to the processing equipment through a conveying structure. And in order to ensure that the semi - finished pick - teeth are always arranged vertically on the conveying structure, a docking cylinder that fits the bottom of the pick - tooth is usually equipped on the conveying structure. In addition, in order to make full use of the internal space of the processing equipment, multiple docking cylinders are usually arranged in a single row on the conveying structure.

[0003] In the conventional method, semi - finished pick - teeth are usually put into the docking cylinder manually or by a robotic arm. Among them, for manual feeding, workers need to manually feed each time according to the rotation rule of the conveying structure, which is slow and prone to missed feeding. In addition, the clamping or grasping ability of the robotic arm is limited, and only one part can be grasped and fed at a time, thus limiting the number of parts fed at a time. Therefore, the above - mentioned methods of feeding by manual and robotic arm both reduce the overall feeding efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an automated single - row pick - tooth feeding device to solve the problem of low overall efficiency of feeding semi - finished pick - teeth into the processing equipment as proposed in the above - mentioned background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: An automated single - row pick - tooth feeding device, comprising: A feeding rack for intermittently pushing several rows of pick - tooth parts backward; A processing box and a conveying structure. The conveying structure passes through the inside of the processing box from front to back, and several rows of docking cylinders are installed on the conveying structure; A guiding component installed on the feeding rack, which lifts the last row of pick - tooth parts upward when several rows of pick - tooth parts on the feeding rack are pushed backward; The transfer mechanism includes an electric guide rail. The electric guide rail is connected to a hydraulic cylinder. The top of the hydraulic cylinder is connected to a clamping component. The electric guide rail is also connected to a telescopic rod. The top of the telescopic rod is installed with a guiding component. Concave inner slide rails are installed on both sides of the guiding component. The clamping component is slidably connected to the concave inner slide rails. When the hydraulic cylinder contracts to drive the row of pick - tooth parts clamped by the clamping component to be inserted into the docking cylinder, the guiding component first makes the bottom of the pick - tooth part contact the docking cylinder.

[0006] Preferably, the diameter of the neck section of the pick part is the same as the inner diameter of the docking cylinder.

[0007] Preferably, the guiding assembly includes an assembly plate connected to two telescopic rods. An upper induction plate corresponding to the single-row pick part is installed on the front surface of the assembly plate, and the inner diameter of the upper induction plate is the same as the diameter of the tooth body of the pick part.

[0008] Preferably, a lower induction plate electrically connected to the conveying structure is installed at the bottom of the upper induction plate. The lower induction plate is semi-circular, and its inner diameter is the same as the outer diameter of the docking cylinder.

[0009] Preferably, the height of the lower induction plate is greater than the height of the neck section of the pick part. When the bottom of the pick part is at the same height as the top surface of the docking cylinder, the top of the lower induction plate is at the same horizontal plane as the top of the docking cylinder.

[0010] Preferably, the feeding rack includes a rack frame arranged in front of the processing box. A plurality of strip-shaped grooves arranged side by side are formed at the top of the rack frame. The inner width of the strip-shaped grooves is the same as the diameter of the tooth body of the pick part. A pushing structure is installed on the rack frame, and a sensor electrically connected to the pushing structure is fitted on the rear wall of the strip-shaped grooves.

[0011] Preferably, the guiding assembly includes a guiding plate installed on the rack frame. The guiding plate is provided with guiding grooves and limiting grooves having the same number as the strip-shaped grooves, and the guiding grooves and the limiting grooves are communicated with each other; The guiding grooves are inclined upward from front to back. The limiting grooves are semi-circular with a curvature radius consistent with the diameter of the neck section. When the bottom of the last row of pick parts fits against the bottom wall of the limiting grooves, this row of pick parts is higher than the adjacent row of pick parts.

[0012] Preferably, a notch communicated with the guiding grooves is formed at the bottom of the guiding plate, and the front-back length of the notch is adapted to the net distance between two adjacent neck sections before and after. An elastic structure is installed at the bottom of the guiding plate, and the top of the elastic structure is connected with an inclined plane block passing through the notch; The inclination of the inclined plane block is greater than the inclination of the bottom wall of the guiding groove. The inner diameter of the ring formed by enclosing between the back surface of the inclined plane block and the rear wall of the limiting groove is the same as the diameter of the neck section.

[0013] Preferably, the clamping assembly includes a horizontal frame connected to the free end of the hydraulic cylinder. A lead screw is rotatably connected inside the horizontal frame. A plurality of clamps are sleeved on the lead screw. When a servo motor for adjusting the plurality of clamps from being open to being closed is installed on one side of the horizontal frame and the lead screw rotates.

[0014] With the above technical solutions, the present invention provides an automatic single-row pick feeding device, which at least has the following beneficial effects: 1. Through the collaborative operation of the clamping assembly, the electric guide rail, and the hydraulic cylinder, the present invention can complete the feeding operation of a whole row of pick teeth parts into the processing box within a short time, reducing manual intervention and effectively improving work efficiency.

[0015] 2. In the present invention, there is a linkage between the conveying structure and the transfer mechanism. After the conveying structure intermittently pauses, the center of the docking cylinder arranged vertically at the frontmost side of its upper surface can be on the same vertical axis as the centers of the upper induction plate, the lower induction plate, and the pick teeth part that is clamped and moved backward to the set position through the transfer mechanism, so as to facilitate the subsequent operation of the hydraulic cylinder to accurately insert a row of pick teeth parts downward into the docking cylinder at the set position, achieving the purpose of precise feeding.

[0016] 3. When the present invention pushes several rows of pick teeth parts from front to back through the propulsion structure, it can use the guiding groove and the limiting groove to lift the last row of pick teeth parts upward, making its height slightly higher than that of the adjacent row of pick teeth parts, thus facilitating the subsequent support clamping of the clamping assembly.

[0017] 4. When the outer wall of the rear side of the last row of pick teeth parts on the feeding rack fits against the rear wall of the limiting groove, the extrusion force on the elastic structure is cancelled. When it resets, it will drive the inclined plane block to move upward, making the back surface of the inclined plane block fit against the outer wall of the front side of the last row of pick teeth parts, ensuring that after it is lifted upward subsequently, it can stably maintain a vertical state, thereby reducing the error when the subsequent clamping assembly clamps the last row of pick teeth parts.

[0018] 5. By centrally placing the pick teeth parts and transferring and feeding them in batches in large quantities, the present invention can not only improve the usage efficiency of each structure in the device, but also achieve precise feeding management of the pick teeth parts through programmed control, which is more efficient than feeding one by one.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. In the description of the present invention, 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, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0022] Embodiment 1 Please refer to Figures 1-8, in this embodiment, an automatic single-row pick-up tooth feeding device is proposed. The feeding device mainly consists of a feeding rack 100, a processing box 300 with a conveying structure 400, a transfer mechanism 500, and a guiding component 600. The feeding rack 100 includes a rack frame 101 disposed in front of the processing box 300. A plurality of strip-shaped grooves 102 arranged side by side are formed at the top of the rack frame 101. The inner width of the strip-shaped grooves 102 is consistent with the diameter of the tooth body 202. A pushing structure 103 is installed on the rack frame 101, and a sensor 104 electrically connected to the pushing structure 103 is fitted in the rear wall of the strip-shaped grooves 102. Among them, the plurality of strip-shaped grooves 102 formed on the rack frame 101 can store a large amount of pick-up tooth parts 200 at a time. And by intermittently operating the pushing structure 103, the purpose of intermittently pushing several rows of pick-up tooth parts 200 backward can be achieved. During the pushing process, when the sensor 104 senses the extrusion force from the last row of pick-up tooth parts 200, the operation of the pushing structure 103 is stopped. The transfer mechanism 500 is used to synchronously clamp the last row of pick-up tooth parts 200 on the feeding rack 100 and insert them into the innermost row of docking cylinders 401 arranged vertically at the front side. The guiding component 600 is used to guide the last row of pick-up tooth parts 200 that reach the designated position to lift upward when the feeding rack 100 pushes several rows of pick-up tooth parts 200 from front to back, so as to leave enough clearance between the bottom of the middle convex part and the top surface of the feeding rack 100.

[0023] Among them, the transfer mechanism 500 includes two electric guide rails 501 disposed on both sides of the feeding rack 100. The structural composition, function, and operation mode of the electric guide rail 501 are basically the same as those in the prior art, so they will not be described in detail here. Its purpose is to drive the supporting slider to move along the front-back axial direction according to a set program after operation. A hydraulic cylinder 502 is installed on the electric guide rail 501 through the slider. The top of the hydraulic cylinder 502 is connected with a clamping component 503. A telescopic rod 504 is fixedly installed at the top of the tail end of the electric guide rail 501. A guiding component 505 is installed at the top of the telescopic rod 504. Concave slide rails 506 are installed on both sides of the guiding component 505. The clamping component 503 is slidably connected to the concave slide rails 506. In the initial state, the hydraulic cylinder 502 is located at a set position in the front section of the electric guide rail 501 and is in an extended state itself, so that the clamping component 503 is located directly above the last row of pick-up tooth parts 200. The electric guide rail 501 is applied in the first embodiment mainly to achieve the purpose of moving axially back and forth through the hydraulic cylinder 502 and its related structures installed on the supporting slider. The hydraulic cylinder 502 is mainly used to control the up-down axial position adjustment of the clamping component 503.

[0024] Based on the above, the transfer and loading process of the last row of pick parts 200 on the feeding rack 100 is as follows: The pick parts 200 are arranged in an orderly manner in multiple rows front and back on the feeding rack 100, and several rows of pick parts 200 are intermittently pushed forward by the feeding rack 100 by a set distance, which is basically consistent with the data at the largest diameter in the middle of the pick parts 200, so that the last row of pick parts 200 reaches the designated position. During this process, the guiding component 600 can be used to lift the last row of pick parts 200 by a certain distance. The hydraulic cylinder 502 contracts inward by a set distance, controlling the clamping component 503 to move downward until its bottom fits the top surface of the feeding rack 100. Then, through the relevant operations of the clamping component 503, the last row of pick parts 200 is synchronously clamped. Then, through the coordinated operation of the hydraulic cylinder 502 and the electric guide rail 501, the clamping component 503 holding a row of pick parts 200 is controlled to move along a trajectory of first upward, then backward, and then downward, so that the clamping component 503 drives the clamped row of pick parts 200 to separate from the feeding rack 100, and finally transfers it to a row of docking cylinders 401 arranged vertically at the frontmost set position on the conveying structure 400. As the hydraulic cylinder 502 contracts again, the pick parts 200 are inserted into the docking cylinders 401, and then the clamping component 503 releases the pick parts 200. And with the intermittent operation of the conveying structure 400, the docking cylinders 401 with pick parts 200 can be rotated into the processing box 300 for corresponding processing. In this embodiment, the processing box 300 can be a heat treatment device. Then, through the coordinated operation of the electric guide rail 501 and the hydraulic cylinder 502, the clamping component 503 is driven back to its original position to perform the feeding of the last row of pick parts 200 in the next round.

[0025] And when the hydraulic cylinder 502 on the slider controlled by the electric guide rail 501 moves backward, the clamping component 503 can follow and slide backward along the concave slide rail 506; when the hydraulic cylinder 502 contracts to drive the clamping component 503 to move downward, it can drive the guiding component 505 to move downward together through the coordination of the concave slide rail 506 and the telescopic rod 504.

[0026] It can be seen that in this embodiment, the coordinated operation of the clamping component 503, the electric guide rail 501, and the hydraulic cylinder 502 can complete the feeding operation process of a whole row of pick parts 200 into the processing box 300 in a short time, reduce manual intervention, and effectively improve work efficiency.

[0027] Embodiment 2 Continuing from the above-mentioned first embodiment, when the row of pick - up teeth parts 200 clamped by the transfer mechanism 500 is moved to the set position according to the set program and the conveying structure 400 stops running, the position of the row of docking cylinders 401 arranged vertically at the front - most side may deviate from the set position. As a result, it will be difficult for the row of pick - up teeth parts 200 clamped by the subsequent clamping assembly 503 to be inserted into this row of docking cylinders 401. To effectively solve this problem, as Figures 5-7 shown, the guiding assembly 505 includes an assembly plate 5051 connected to two telescopic rods 504. On the front surface of the assembly plate 5051, upper induction plates 5052 with the same number as the single - row pick - up teeth parts 200 are installed. The inner diameter of the upper induction plates 5052 is the same as the diameter of the tooth body 202 in the pick - up teeth parts 200. At the bottom of the upper induction plates 5052, lower induction plates 5053 electrically connected to the conveying structure 400 are installed. The lower induction plates 5053 are semi - circular, and their inner diameter is the same as the outer diameter of the docking cylinders 401. The height of the lower induction plates 5053 is greater than the height of the neck section 204 of the pick - up teeth parts 200. When the transfer mechanism 500 is used to move the last row of pick - up teeth parts 200 on the feeding rack 100 so that the bottom of them is at the same height as the top surface of the docking cylinders 401 arranged vertically on the upper surface of the conveying structure 400, the top of the lower induction plates 5053 is at the same horizontal plane as the top of this row of docking cylinders 401.

[0028] As Figure 7 shown, when the clamping assembly 503 clamps the last row of pick - up teeth parts 200 on the feeding rack 100, the bottom of the upper induction plates 5052 is at the same height as the top surface of the docking cylinders 401 on the upper surface of the conveying structure 400, while the lower induction plates 5053 are located below this row of docking cylinders 401. Therefore, during the subsequent low - speed rotation of the conveying structure 400, the row of docking cylinders 401 rotating upward from the front side will come into contact with the lower induction plates 5053. The lower induction plates 5053 are embedded with pressure sensors. When they sense the extrusion force generated when the docking cylinders 401 move backward, they will generate electrical signals and feedback them to the conveying structure 400 electrically connected to them, giving a signal for the conveying structure 400 to stop running.

[0029] Meanwhile, during the process of using the electric guide rail 501 and the hydraulic cylinder 502 to control the clamping assembly 503 that holds a row of pick parts 200 and moves backward, when the back surface of the pick part 200 comes into contact with the inner wall of the recess of the upper induction plate 5052, the electric guide rail 501 electrically connected to the upper induction plate 5052 stops operating, indicating that the center of the pick part 200 that has moved backward to the set position is on the same vertical axis as the center of the upper induction plate 5052. Additionally, when the hydraulic cylinder 502 contracts and drives the row of pick parts 200 held by the clamping assembly 503 to be inserted into the docking cylinder 401, the inner wall of the recess of the lower induction plate 5053 in the guiding assembly 505 comes into contact with the docking cylinder 401. Therefore, the centers of the rows of docking cylinders 401 are on the same vertical axis as the centers of the semi-circular lower induction plate 5053 and upper induction plate 5052. After that, when the electric guide rail 501 pushes the hydraulic cylinder 502 backward by a set distance, the hydraulic cylinder 502 contracts downward, and can accurately insert a row of pick parts 200 held by the clamping assembly 503 downward into the docking cylinder 401 at a specific position.

[0030] Embodiment Three As Figure 2 and Figure 8 shown, the guiding assembly 600 includes a guiding plate 601 installed on the rack frame 101. The guiding plate 601 is provided with guiding grooves 6011 and limiting grooves 6012 that are the same in number as the strip-shaped grooves 102, and the guiding grooves 6011 and the limiting grooves 6012 communicate with each other. The guiding grooves 6011 are inclined upward from front to back, and the limiting grooves 6012 are semi-circular with a curvature radius consistent with the diameter of the neck section 204. When the bottom of the last row of pick parts 200 fits against the bottom wall of the limiting groove 6012, this row of pick parts 200 is higher than the adjacent row of pick parts 200.

[0031] Combined with the above Embodiment One, by neatly stacking a large number of pick parts 200 in several columns of strip-shaped grooves 102, and then cooperating with the pushing structure 103, multiple rows of pick parts 200 are pushed forward once. As the last row of pick parts 200 is pushed by the pushing structure 103, its bottom can enter the range of the limiting groove 6012 with a horizontal bottom wall under the guidance of the inclined bottom wall of the rear half of the guiding groove 6011. At this time, this row of pick parts 200 will be lifted by the bottom wall of the limiting groove 6012, making its height slightly higher than that of the adjacent row of pick parts 200, thus facilitating the supporting clamping of the subsequent clamping assembly 503.

[0032] Embodiment Four Continuing from the above-mentioned Embodiment 3, a notch communicating with the guiding groove 6011 is provided at the bottom of the guiding plate 601, and the front-back length of the notch is adapted to the net distance between two adjacent neck segments 204 in the front-back direction. An elastic structure 602 is installed at the bottom of the guiding plate 601. The top of the elastic structure 602 is connected to an inclined plane block 603 passing through the notch. The inclination of the inclined plane block 603 is greater than that of the bottom wall of the guiding groove 6011. An annular shape is formed by enclosing between the back surface of the inclined plane block 603 and the rear wall of the limiting groove 6012, and its inner diameter is the same as the diameter of the neck segment 204. And it is set that when the top surface of the inclined plane block 603 is adjusted to a height position lower than the top of the notch, the force required to squeeze the elastic structure 602 is less than the gravity of the pick part 200. Therefore, as the propulsion structure 103 operates and drives the last row of pick parts 200 to move backward along the inclined top surface of the inclined plane block 603, the inclined plane block 603 will contract downward to avoid hindering the backward movement of the last row of pick parts 200, so that the pick parts 200 accurately enter the range of the limiting groove 6012. And at this time, the extrusion force received by the elastic structure 602 is cancelled, and it returns to its original state, forming a circular cavity that fits the bottom diameter of the pick part 200 with the rear wall of the limiting groove 6012, and this circular cavity is closely attached to the outer side of the bottom of the pick part 200 to be transferred, ensuring that it can stably maintain a vertical state after being lifted upward subsequently, reducing subsequent clamping errors.

[0033] Embodiment 5 As Figure 7 and Figure 8 shown, the pick part 200 is composed of a tooth head 201, a tooth body 202, a shoulder ring 203 sleeved in the middle of the tooth body 202, and a neck segment 204 provided at the bottom of the tooth body 202. The diameter of the neck segment 204 is smaller than that of the tooth body 202 and is the same as the inner diameter of the docking cylinder 401. The clamping assembly 503 includes a cross frame 5031 connected to the free end of the hydraulic cylinder 502. A lead screw 5032 is rotatably connected in the cross frame 5031. A number of clamps 5033 are sleeved on the lead screw 5032. When a servo motor 5034 that drives the lead screw 5032 to rotate and adjusts a number of clamps 5033 from being open to being closed is installed on one side of the cross frame 5031. The inner cavity of the clamp 5033 fits with the part of the tooth body 202 with the shoulder ring 203. And the thickness of the bottom plate of the clamp 5033 is smaller than the distance between the bottom of the shoulder ring 203 and the top surface of the feeding rack 100 when the last row of pick parts 200 on the feeding rack 100 is lifted upward. Therefore, by using the clamping assembly 503 to clamp the last row of pick parts 200, this row of pick parts 200 not only receives clamping forces from both sides, but also the bottom of the shoulder ring 203 in the pick part 200 receives a lifting force. The two combined can effectively prevent the clamped pick parts 200 from slipping downward, thereby effectively ensuring the stability of clamping.

[0034] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention should cover within the protection scope of the present invention by making equivalent substitutions or changes according to the technical solution and inventive concept of the present invention.
