Description

Technical Field

[0001] This invention relates to the field of matching and conveying technology for metal billet grinding, specifically to a billet matching and conveying mechanism for a metal grinding machine. Background Technology

[0002] Metal billets refer to semi-finished raw materials for metal processing. They are made into specific shapes through different processes and used for subsequent processing into final products. Among the various processing steps is grinding, which is a process of removing surface defects with tools such as grinding wheels. This can improve material quality and subsequent processing efficiency. Currently, most large metal billets are processed by gantry-type grinding machines. With the help of a conveying mechanism for the metal billets, the metal billets are moved during the grinding process, thereby driving the metal billets to contact the grinding machine for the required surface grinding.

[0003] Application CN220055099U discloses a metal plate cutting, conveying, and positioning structure. By utilizing the special design of the conveyor belt, the metal plates are separated, avoiding scratches caused by large-area contact and sliding of the metal plates. At the same time, the cyclical nature of the conveyor belt allows the device to be added without affecting its use. Furthermore, the entire structure is simple and can be expanded to be used with different cutting equipment as needed, making it highly suitable for mass production in factories.

[0004] Application CN118665917B discloses an independent conveying device for non-ferrous metal processing, which is equipped with a support plate. By setting the support plate in an inclined direction, gas can be generated inside the sealed container. The gas acts on the gas delivery pipe and the internal parts of the cooperating mechanism, which can limit the non-ferrous metal sheets and adsorb and clean the waste on the top of the non-ferrous metal sheets, thus making the non-ferrous metal sheets more effectively processed during the conveying process.

[0005] However, the aforementioned conveying device for metal billet processing still has the following problems in actual use: the metal billet is driven for processing through the positioning mechanism and the conveying mechanism, but during the grinding operation, the entire surface of the metal billet and the required surface need to be brought into contact with the grinding machine. Conventional grinding machines can be moved to process in different directions, but they cannot cover large-sized metal billets for processing. At the same time, the existing matching conveying device cannot flip the billet, and manual assistance is required for adjustment, which affects processing efficiency and grinding accuracy.

[0006] Therefore, we propose a blank matching and conveying mechanism for a metal grinding machine to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a blank matching and conveying mechanism for a metal grinding machine. This addresses the problem that existing methods use positioning and conveying mechanisms to move metal blanks for processing, but during grinding operations, the entire surface of the metal blank and the desired surface need to be in contact with the grinding machine. Conventional grinding machines can move to process in different directions, but they cannot cover large-sized metal blanks for processing. At the same time, existing matching and conveying devices cannot flip the blanks, requiring manual adjustment, which affects processing efficiency and grinding accuracy.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a blank matching and conveying mechanism for a metal grinding machine, comprising a conveying platform, wherein a conveying cavity is formed inside the left end of the conveying platform; further comprising: The conveying platform is equipped with a conveying mechanism, which includes a conveying frame. The lower end of the conveying frame slides through a conveying cavity opened at the left end of the conveying platform. The upper end of the conveyor frame slides against the top surface of the conveyor platform to move the metal billet and adjust its conveying during the grinding process. A positioning mechanism is provided above the conveyor frame, and the positioning mechanism includes a main positioning slide and a secondary positioning slide.

[0009] Preferably, the conveying mechanism includes a conveying screw, which is rotatably mounted on the front and rear sides of the conveying cavity inside the conveying platform via bearings, and the left ends of the symmetrically distributed conveying screws are interconnected via pulley assemblies.

[0010] Preferably, the conveying mechanism includes a conveying sleeve, which is fixedly installed on the front and rear sides of the left end of the conveying platform. The conveying sleeve is threaded onto the outside of the conveying screw, and the conveying sleeve slides in the left and right directions with the conveying platform by the rotation of the conveying screw.

[0011] Preferably, the positioning mechanism includes a main positioning slide plate fixedly installed on the left and right sides behind the top surface of the conveyor frame, and a secondary positioning slide plate included in the positioning mechanism is slidably installed on the left and right sides in front of the top surface of the conveyor frame, and the symmetrically distributed main positioning slide plate and secondary positioning slide plate are symmetrically distributed front and back.

[0012] Preferably, the positioning mechanism includes positioning claws, which are fixedly installed at equal intervals on the inner upper end of the main positioning slide plate and the inner upper end of the auxiliary positioning slide plate. The positioning claws, which are distributed at equal intervals, are arranged in an inclined structure with the upper end pointing inward and the lower end pointing outward. The symmetrically distributed positioning claws contact the outer wall of the metal billet through the inclined surface at the upper end.

[0013] Preferably, a flipping mechanism is provided above the conveying platform, and the flipping mechanism includes a flipping frame. The flipping frame is arranged in an inverted right-angled triangle structure and is evenly distributed behind the top surface of the conveying platform, with the right-angled sides of the flipping frame distributed outward.

[0014] Preferably, the flipping mechanism includes a flipping shaft, which is rotatably mounted on the front of the top of the conveying platform via a bearing. The flipping shaft is also disposed at the lower end of the flipping frame, which is equidistant from each other. The end of the flipping frame closest to the front of the conveying platform flips downward under the influence of gravity and is tilted. Furthermore, flipping blocks are fixedly disposed at equal intervals on the upper surface of the flipping frame.

[0015] Preferably, the flipping mechanism includes an abutting slider, which is slidably disposed above the top surface of the conveyor frame. The side of the abutting slider near the flipping frame is inclined, and the abutting slider is in contact with the inclined surface of the flipping frame through the upper inclined surface. The flipping mechanism includes a stop vertical plate, which is fixedly installed below the inclined surface of the flipping frame. The stop vertical plate is used to abut against the rear end of the contact slider to control the distance the contact slider moves backward, so that the flipping frame reaches a horizontal state through the pressure of the contact slider.

[0016] Preferably, the flipping mechanism includes a flipping screw rotatably mounted on the center position inside the conveyor frame, and the flipping screw is threaded through and connected to the lower end of the middle contact slider of the conveyor frame. A transmission slide is fixedly installed below the front of the middle contact slider, and the transmission slide is fixedly connected to the secondary positioning slide plate.

[0017] Preferably, the flipping mechanism includes flipping slide rods fixedly installed on the left and right sides inside the conveying platform, and the flipping slide rods slide through the lower ends of the abutting sliders on the left and right sides of the conveying platform, and the abutting sliders on the left and right sides are fixedly connected to the outer ends of the transmission slide, so as to drive the flipping frame to rotate after sliding to realize the flipping of the metal billet.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The blank matching and conveying mechanism of the metal grinding machine drives the metal blank for grinding and adjustment through a sliding conveying frame above the conveying platform, and the sliding of the positioning gripper and the flipping frame drives the metal blank to rotate and flip, thereby improving the efficiency of matching, conveying and flipping of heavy metal blanks of different specifications during grinding operations. The specific details are as follows: 1. The conveying screw inside the conveying platform rotates and is threadedly connected to the conveying sleeve inside the conveying frame. This causes the conveying frame to move left and right relative to the conveying platform, and adjusts the metal billet positioned above by the positioning and flipping mechanisms to adapt to different grinding operations.

[0019] 2. The metal billet is placed above the flipping frame. The flipping screw inside the conveyor frame rotates, causing the threaded contact slider and transmission slide to slide inward. This causes the secondary positioning slide and the positioning jaws above to approach the metal billet, thereby positioning the metal billet of different specifications.

[0020] Furthermore, after the front positioning jaws contact the metal blank, they drive the metal blank to slide backward, contact the positioning jaws at the upper end of the rear main positioning slide plate, and are clamped and limited by the front positioning jaws, thereby preventing misalignment during grinding.

[0021] 3. When a metal billet with a finished surface grinding needs to be flipped, the flipping screw drives the sliding block to slide forward. The inclined surface no longer presses against the inclined surface of the flipping frame, so that the flipping frame drives the metal billet above to flip downward by gravity. The lower end of the metal billet is resisted by the flipping block, so that it rotates when tilting downward, causing the ground surface to rotate downward and the unground surface to rotate upward for grinding.

[0022] Furthermore, the flipping screw drives the contact slider to slide inward. The inclined surface of the contact slider presses against the inclined surface of the flipping frame, causing the flipping frame to rotate the metal billet above upward. When the rear end of the contact slider comes into contact with the stop vertical plate, it forms a limit, causing the flipping frame to straighten the metal billet above, and then clamp and position it again through the symmetrically distributed positioning jaws for subsequent grinding.

[0025] The technical solutions of 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 of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-10 The present invention provides the following technical solution: Example 1: To solve the problem of blank matching and conveying in existing grinding machines, this example discloses the following technical solution: a blank matching and conveying mechanism for a metal grinding machine, including a conveying platform 1, and a conveying cavity 2 is provided inside the left end of the conveying platform 1; a conveying mechanism is provided inside the conveying platform 1, and the conveying mechanism includes a conveying frame 3, and the lower end of the conveying frame 3 is slidably disposed in the conveying cavity 2 opened inside the left end of the conveying platform 1; wherein, the upper end of the conveying frame 3 is attached to and slides against the top surface of the conveying platform 1, and is used to drive the metal blank 10 to be adjusted and conveyed during the grinding process.

[0027] The conveying mechanism includes a conveying screw 6, which is rotatably mounted on the front and rear sides of the conveying cavity 2 inside the conveying platform 1 via bearings, and the left ends of the symmetrically distributed conveying screws 6 are interconnected via a pulley assembly 7; the conveying mechanism includes a conveying sleeve 8, which is fixedly mounted on the front and rear sides of the left end of the conveying frame 3, and the conveying sleeve 8 is threaded onto the outside of the conveying screw 6, and the rotation of the conveying screw 6 drives the conveying sleeve 8 to slide in the left and right directions with the conveying frame 3.

[0028] like Figures 3-5 As shown, during the grinding process of the metal billet 10, the conveyor frame 3 above the conveyor platform 1 is matched with the grinding machine. The servo motor installed on the right end of the conveyor platform 1 operates, driving the conveyor screw 6 connected to the pulley assembly 7 to rotate. The rotation of the conveyor screw 6 drives the threaded conveyor sleeve 8 to slide with the conveyor frame 3. During the sliding process, the upper end of the conveyor frame 3 moves on the top surface of the conveyor platform 1, so as to drive the positioning mechanism and the flipping mechanism above to slide and adjust the metal billet 10 to adapt to the grinding operation of the grinding machine.

[0029] Example 2: To solve the problems existing in the matching and conveying of blanks in existing grinding machines, this example discloses the following technical solution: a blank matching and conveying mechanism for a metal grinding machine, wherein a positioning mechanism is provided above the conveying platform 3, and the positioning mechanism includes a main positioning slide plate 4 and a secondary positioning slide plate 5; the main positioning slide plate 4 is fixedly installed on the left and right sides behind the top surface of the conveying platform 3, and the secondary positioning slide plate 5 is slidably installed on the left and right sides in front of the top surface of the conveying platform 3, and the symmetrically distributed main positioning slide plate 4 and secondary positioning slide plate 5 are symmetrically distributed front and back; the positioning mechanism includes positioning claws 9, and the positioning claws 9 are fixedly installed at equal distances on the upper inner side of the main positioning slide plate 4 and the upper inner side of the secondary positioning slide plate 5, and the equidistantly distributed positioning claws 9 are distributed in an inclined structure with the upper end pointing inward and the lower end pointing outward, and the symmetrically distributed positioning claws 9 contact the outer wall of the metal blank 10 through the inclined surface at the upper end.

[0030] like Figures 6-8 As shown, when positioning and clamping metal blanks 10 of different specifications, the metal blanks 10 to be processed are first placed on the top surface of the flipping frame 11 above the conveyor frame 3. Then, the servo motor installed at the front end of the conveyor frame 3 works, which drives the fixedly connected flipping screw 16 to rotate. The flipping screw 16 drives the threadedly connected abutment slider 13 and transmission slide 17 to move. During the movement of the transmission slide 17, the auxiliary positioning slides 5 on the left and right sides and the positioning grippers 9 move towards one side of the metal blank 10 in sync, thereby adapting to metal blanks 10 of different specifications.

[0031] Furthermore, as the auxiliary positioning slide plates 5 on the left and right sides of the front of the conveying platform 3 move backward, the positioning claws 9 at their upper ends contact the metal blank 10 and move backward, causing the metal blank 10 to slide to the end of the positioning claws 9 at the upper end of the main positioning slide plate 4. Thus, the positioning claws 9 on the front and rear sides position and clamp the metal blanks 10 of different specifications, thereby avoiding misalignment or displacement during the grinding process.

[0032] Example 3: To solve the problems existing in the matching and conveying of blanks in the existing grinding machine, this example discloses the following technical solution: a blank matching and conveying mechanism for a metal grinding machine, wherein a flipping mechanism is provided above the conveying platform 3, and the flipping mechanism includes a flipping frame 11, and the flipping frame 11 is distributed in an inverted right-angled triangle structure, and the flipping frame 11 is evenly distributed behind the top surface of the conveying platform 3, with the right-angled sides of the flipping frame 11 distributed outwards; the flipping mechanism includes a flipping shaft 12, and the flipping shaft 12 is rotatably installed in front of the top surface of the conveying platform 3 through a bearing, and the flipping shaft 12 is disposed through the lower end of the evenly distributed flipping frame 11, the end of the flipping frame 11 near the front surface of the conveying platform 3 is flipped downwards and tilted under the gravitational potential energy, and flipping blocks 15 are fixedly arranged at equal intervals on the upper surface of the flipping frame 11.

[0033] The flipping mechanism includes an abutting slider 13, which is slidably disposed above the top surface of the conveyor frame 3. The side of the abutting slider 13 closest to the flipping frame 11 is inclined, and the abutting slider 13 is in contact with the inclined surface of the flipping frame 11 through its upper inclined surface. The flipping mechanism includes a stop vertical plate 14, which is fixedly installed below the inclined surface of the flipping frame 11. The stop vertical plate 14 is used to contact with the rear end of the abutting slider 13 to control the distance the abutting slider 13 moves backward, so that the flipping frame 11 reaches a horizontal state through the compression of the abutting slider 13.

[0034] The flipping mechanism includes a flipping screw 16 rotatably mounted on the center of the conveyor frame 3, and the flipping screw 16 is threaded through and connected to the lower end of the contact slider 13 in the middle of the conveyor frame 3. A transmission slide 17 is fixedly mounted on the lower front of the contact slider 13 in the middle, and the transmission slide 17 is fixedly connected to the auxiliary positioning slide plate 5. The flipping mechanism includes flipping slide rods 18 fixedly mounted on the left and right sides inside the conveyor frame 3, and the flipping slide rods 18 slide through the lower ends of the contact sliders 13 on the left and right sides of the conveyor frame 3. The contact sliders 13 on the left and right sides are fixedly connected to the outer end of the transmission slide 17, which is used to drive the flipping frame 11 to rotate after sliding to achieve the flipping of the metal billet 10.

[0035] like Figures 8-10As shown, when the upper surface of the metal billet 10 needs to be flipped after grinding, the flipping screw 16 inside the conveyor frame 3 rotates, which drives the threaded contact slider 13 to move. During the movement of the contact slider 13, the transmission slide 17 moves synchronously with the contact sliders 13 at both ends. When the contact sliders 13, which are evenly distributed, move, they no longer press against the flipping frame 11 connected by the inclined surface. This causes the flipping frame 11 to rotate downward through the flipping shaft 12 at the bottom. The metal billet 10 placed on the upper end of the flipping frame 11 contacts the flipping block 15, causing the inclined metal billet 10 to be flipped, so that the un-grinded side rotates upward and the ground surface rotates downward, thus completing the flipping process.

[0036] Furthermore, after the metal billet 10 completes its rotation and flipping, the flipping screw 16 inside the conveyor frame 3 rotates in the opposite direction, thereby driving the contact slider 13 to slide inward. The inclined surface of the contact slider 13 presses against the inclined surface of the flipping frame 11, causing the flipping frame 11 to drive the metal billet 10 above to rotate upward. When the rear end of the contact slider 13 is in contact with the stop vertical plate 14, it forms a limit and causes the flipping frame 11 to drive the metal billet 10 above to be straightened, so that it is clamped and positioned again by the symmetrically distributed positioning claws 9 for subsequent grinding processing.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
