Description

Technical Field

[0001] The utility model relates to the technical field of straightening machine material pushing, in particular to a left and right baffle follower self - resetting mechanism for a pusher. Background Technique

[0002] An automatic straightening machine is an automatic detection and straightening device designed for the bending deformation of shaft - like products after heat treatment. It is a product integrating machinery, electricity, hydraulics, pneumatics, and computer measurement and control analysis.

[0003] At present, when the straightening machine straightens shaft - like products, most of them intermittently convey the workpieces through a conveyor belt, and then clamp them manually or automatically by a manipulator for straightening processing. However, when loading materials on the conveyor belt, it is basically done manually, with poor work efficiency and low automation. Although some conveyor belts can load materials automatically, they cannot stably clamp shaft - like products during loading, resulting in poor loading stability. Therefore, we provide a left and right baffle follower self - resetting mechanism for a pusher to solve this problem. Content of the Utility Model

[0005] In order to achieve the above - mentioned purpose, the utility model adopts the following technical scheme:

[0006] Design a left and right baffle follower self - resetting mechanism for a pusher, including a concave - shaped frame. Both sides of the concave - shaped frame are provided with chutes. One side of the concave - shaped frame is connected with a back plate. A material - placing component is installed in the inner cavity of the concave - shaped frame, and a material - pushing mechanism is installed at the bottom end of the inner cavity of the concave - shaped frame;

[0007] The material - pushing mechanism includes a servo motor installed at the bottom end inside the concave - shaped frame. The output end of the servo motor is connected with a first bevel gear. The outside of the first bevel gear is meshed with a second bevel gear. A first lead screw is installed in the inner cavity of the second bevel gear. A bearing seat is installed at the bottom end inside the concave - shaped frame and is rotationally connected with the first lead screw. A material - pushing frame is screwed on the outside of the first lead screw. Symmetrically - connected extension plates are installed on the upper part of the outside of the material - pushing frame. A material - blocking component is installed at the upper end of the extension plate. The extension plate passes through the chute and extends to the outside. A third bevel gear is installed at the output end of the servo motor. The outside of the third bevel gear is symmetrically meshed with fourth bevel gears. Transmission shafts are connected to the inner cavities of the fourth bevel gears. Support seats are installed at the bottom end inside the concave - shaped frame and are rotationally connected with the transmission shafts. One end of each transmission shaft is connected with a second lead screw. The second lead screws all penetrate through the concave - shaped frame and are screwed with threaded sleeves. A telescopic push plate is connected to the outside of the threaded sleeve. The telescopic push plate is connected with the material - blocking component.

[0008] Furthermore, the feeding component includes an inclined bearing plate screwed inside the concave frame. The right side of the inclined bearing plate is connected to a second vertical plate. A placing groove is arranged at the upper end of the second vertical plate. The second vertical plate is in contact with the pushing frame.

[0009] Furthermore, a first vertical plate is connected to the left side of the inclined bearing plate.

[0010] Furthermore, the material blocking component includes a fixed cover installed at the upper end of the extension plate. A baffle is arranged on one side of the fixed cover. The telescopic push plate is connected to an outer tube. An inner column is movably sleeved in the inner cavity of the outer tube. The outer tube is movably inserted between the fixed cover. A first spring is connected to the inner cavity of the outer tube. One end of the first spring is connected to the inner column. One end of the inner column is inserted into the inner cavity of the fixed cover and then connected to the baffle.

[0011] Furthermore, an electromagnet is installed on the outer side of the inner column.

[0012] Furthermore, an installation groove is arranged at the lower end of the baffle. An arc-shaped pressing column is connected to the inner cavity of the installation groove through a third spring.

[0013] Furthermore, a bottom plate is connected to the right side of the pushing frame. A movable plate is movably connected to the right side of the pushing frame through a hinge. Fixed columns are equidistantly connected to the lower end of the movable plate. Second springs are equidistantly installed at the upper end of the bottom plate and are in position matching with the second springs. The upper ends of the second springs are in contact with the movable plate. The fixed columns are all located in the inner cavities of the second springs.

[0014] Furthermore, side plates are symmetrically installed at the upper end of the back plate. Blocking strips are connected to the corresponding sides of the side plates.

[0015] A left and right baffle follower self-resetting mechanism for a pusher has the beneficial effects that:

[0016] 1. While pushing the workpiece through the pushing frame of the pushing mechanism, the workpiece is synchronously limited, blocked and clamped by the material blocking component. And when the pushing frame resets, the baffle of the material blocking component moves away from the workpiece, which is convenient for the workpiece to be unloaded. And the material blocking component resets synchronously with the pushing frame, which is convenient for repeating the pushing and unloading operation, effectively improving the automatic pushing and unloading operation, and facilitating the avoidance of the workpiece falling when pushing the workpiece, effectively improving the stability of the feeding and transportation.

[0017] 2. While the baffle of the material blocking component clamps the workpiece, the third spring and the arc-shaped pressing column in the inner cavity of the installation groove at the lower end of the baffle move above the movable plate, and the compressed third spring drives the arc-shaped pressing column to press down the movable plate, which is convenient for the workpiece on the pushing frame and the upper end of the movable plate to naturally fall along the inclined movable plate, facilitating the automatic and stable pushing and unloading, and effectively improving the use effect.

Detailed Description of the Preferred Embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0028] Refer to Figure 1-8, A left and right baffle follower self - resetting mechanism for a pusher, including a concave - shaped frame 1. A feeding component 4 is installed in the inner cavity of the concave - shaped frame 1. The feeding component 4 includes an inclined bearing plate 41 screwed on the inner side of the concave - shaped frame 1. A first vertical plate 42 is connected to the left side of the inclined bearing plate 41, and a second vertical plate 43 is connected to the right side of the inclined bearing plate 41. A placement groove 44 is arranged at the upper end of the second vertical plate 43, and the second vertical plate 43 is in contact with the pusher frame 56.

[0029] Multiple shaft - type workpieces are placed through the inclined bearing plate 41, and the first vertical plate 42 is used to block the shaft - type workpieces to prevent them from being pushed and falling from the left side of the inclined bearing plate 41. A shaft - type workpiece is placed in the placement groove 44 at the upper end of the second vertical plate 43, and a shaft - type workpiece has rolled onto the upper ends of the pusher frame 56 and the movable plate 518. When the pusher frame 56 pushes this shaft - type workpiece upward, due to the design of the second vertical plate 43 being in contact with the pusher frame 56, the shaft - type workpiece in the placement groove 44 is prevented from falling. And when the pusher frame 56 resets, since there is no shaft - type workpiece at the upper end of the pusher frame 56, and due to the inclined design of the inclined bearing plate 41, the shaft - type workpiece placed at the right - most side at the upper end of the inclined bearing plate 41 automatically rolls towards the placement groove 44, thereby pushing the shaft - type workpiece at the upper end of the placement groove 44 to fall onto the upper end of the pusher frame 56, facilitating the pusher frame 56 to continuously push the workpieces and being convenient for use.

[0030] A pusher mechanism 5 is installed at the bottom end of the inner cavity of the concave - shaped frame 1. The pusher mechanism 5 includes a servo - motor 51 installed at the bottom end of the inner side of the concave - shaped frame 1. The output end of the servo - motor 51 is connected to a first bevel gear 52. A second bevel gear 53 is meshed with the outside of the first bevel gear 52. A first lead screw 54 is installed in the inner cavity of the second bevel gear 53. A bearing seat 55 is installed at the bottom end of the inner side of the concave - shaped frame 1 and is rotationally connected to it. A pusher frame 56 is screwed on the outside of the first lead screw 54.

[0031] The output end of the servo - motor 51 drives the first bevel gear 52 to rotate, and the first bevel gear 52 drives the second bevel gear 53 meshed with it and the first lead screw 54 in its inner cavity to rotate. Subsequently, the first lead screw 54 drives the pusher frame 56 to move upward, facilitating the operation of the pusher frame 56 to push the shaft - type workpieces.

[0032] An extension plate 57 passes through the chute 2 and extends to the outside. A third bevel gear 59 is installed at the output end of the servo - motor 51. Fourth bevel gears 510 are symmetrically meshed with the outside of the third bevel gear 59. Transmission shafts 511 are connected to the inner cavities of the fourth bevel gears 510. Support seats 512 are installed at the bottom end of the inner side of the concave - shaped frame 1 and are rotationally connected to them. Second lead screws 513 are connected to one ends of the transmission shafts 511. The second lead screws 513 all pass through the concave - shaped frame 1 and are screwed with threaded sleeves 514. A telescopic push plate 515 is connected to the outside of the threaded sleeve 514. The telescopic push plate 515 is connected to the material - blocking component 58.

[0033] Chute grooves 2 are provided on both sides of the concave-shaped frame 1. Symmetrically connected to the upper part of the outer side of the material pushing frame 56 are extension plates 57. Mounted at the upper ends of the extension plates 57 are material blocking assemblies 58. The material blocking assembly 58 includes a fixed cover 583 mounted at the upper end of the extension plate 57. Provided on one side of the fixed cover 583 is a baffle plate 584. The telescopic push plate 515 is connected to an outer tube 581. An inner column 582 is movably sleeved in the inner cavity of the outer tube 581. An electromagnet 589 is mounted on the outer side of the inner column 582. The outer tube 581 is movably inserted between the outer tube 581 and the fixed cover 583. Connected to the inner cavity of the outer tube 581 is a first spring 585. One end of the first spring 585 is connected to the inner column 582. One end of the inner column 582 is inserted into the inner cavity of the fixed cover 583 and then connected to the baffle plate 584. Provided at the lower end of the baffle plate 584 is a mounting groove 586. Connected to an arc-shaped pressing column 588 through a third spring 587 in the inner cavity of the mounting groove 586.

[0034] While the output end of the servo motor 51 rotates, it drives the third bevel gear 59 to rotate. The third bevel gear 59 drives two fourth bevel gears 510 and the transmission shafts 511 in their inner cavities to rotate. The transmission shafts 511 drive the second lead screws 513 to rotate. Since the two fourth bevel gears 510 rotate in opposite directions respectively, the two second lead screws 513 rotate in opposite directions respectively. Then the two threaded sleeves 514 on their outer sides move in the same direction. The threaded sleeve 514 drives the telescopic push plate 515 to push the outer tube 581 to move. The upper part of the telescopic push plate 515 also moves upward as the material pushing frame 56 rises. The outer tube 581 drives the inner column 582 to move in the same direction through the first spring 585. The inner column 582 drives the baffle plate 584 to clamp and block the workpieces at the upper ends of the material pushing frame 56 and the movable plate 518, preventing them from falling during pushing, effectively improving the stability of the feeding and transportation. As the material pushing frame 56 continues to move upward, the telescopic push plate 515 continues to push the outer tube 581. When the baffle plate 584 fits against the workpiece, the outer tube 581 starts to compress the first spring 585 and moves toward the inner cavity of the fixed cover 583 until it fits against one end of the electromagnet 589. The outer tube 581 is a magnetic metal, so it is magnetically fixed to the electromagnet 589. At the same time, the material pushing frame 56 moves upward to a position higher than the concave-shaped frame 1 and the back plate 3. Through the reset and downward movement operation of the material pushing frame 56, the material blocking assembly 58 also moves in reset. Then the telescopic push plate 515 drives the outer tube 581 to move in the opposite direction. Since the outer tube 581 is magnetically fixed to the electromagnet 589 on the outer side of the inner column 582, the outer tube 581 first drives the electromagnet 589 and the inner column 582 to move in the opposite direction. Then the inner column 582 drives the baffle plate 584 to leave the surface of the workpiece, facilitating the blanking of the workpiece. Subsequently, the electromagnet 589 is powered off. The compressed first spring 585 first ejects the inner column 582 away from the outer tube 581 in the opposite direction. As the outer tube 581 then drives the inner column 582 to continue to reset through the first spring 585, it is convenient for the next pushing, limiting, blocking, and clamping operations, effectively improving the use effect.

[0035] A base plate 517 is connected to the right side of the pusher frame 56. The right side of the pusher frame 56 is movably connected to a movable plate 518 through a hinge 519. Fixed columns 520 are equidistantly connected to the lower end of the movable plate 518. Second springs 521 that are position-matched thereto are equidistantly installed on the upper end of the base plate 517. The upper ends of the second springs 521 are in contact with the movable plate 518. The fixed columns 520 are all located in the inner cavities of the second springs 521.

[0036] When the baffle 584 moves into the upper end of the pusher frame 56 along with the inner column, the third spring 587 and the arc-shaped pressing column 588 in the inner cavity of the installation groove 586 at the lower end of the baffle 584 move above the movable plate 518, and the compressed third spring 587 drives the arc-shaped pressing column 588 to press down the movable plate 518. Since the elastic performance of the second spring 521 is less than that of the third spring 587, the movable plate 518 inclines downward and compresses the second spring 521. Subsequently, after the pusher frame 56 resets, the baffle 584 of the material blocking assembly 58 leaves both sides of the workpiece, and the workpiece on the upper ends of the pusher frame 56 and the movable plate 518 naturally falls along the inclined movable plate 518, facilitating automatic and stable material pushing, and effectively improving the use effect.

[0037] One side of the concave-shaped frame 1 is connected to a back plate 3. Side plates 6 are symmetrically installed at the upper end of the back plate 3. Blocking strips 7 are connected to the corresponding sides of the side plates 6, which is convenient for further limiting and blocking the workpiece through the side plates 6 and the blocking strips 7 after the pusher frame 56 discharges the material, facilitating the workpiece to stably move down between the two side plates 6, and receiving the workpiece at the lower end of the side plates 6 through an external conveyor for convenient movement and transportation.

[0038] Working principle: The utility model is controlledly connected to a servo motor 51 and an electromagnet 589 through an external controller. During use, the output end of the servo motor 51 drives the first bevel gear 52 to rotate, and the first bevel gear 52 drives the second bevel gear 53 meshed with it and the first lead screw 54 in its inner cavity to rotate. Subsequently, the first lead screw 54 drives the material pushing frame 56 to move upward. At the same time, the output end of the servo motor 51 drives the third bevel gear 59 to rotate, and the third bevel gear 59 drives two fourth bevel gears 510 and the transmission shaft 511 in their inner cavities to rotate. The transmission shafts 511 both drive the second lead screw 513 to rotate, and the two threaded sleeves 514 on its outer side move in the same direction. The threaded sleeves 514 drive the telescopic push plate 515 to push the outer tube 581 to move. The upper part of the telescopic push plate 515 also moves upward as the material pushing frame 56 rises. The outer tube 581 drives the inner column 582 to move in the same direction through the first spring 585. The inner column 582 drives the baffle 584 to clamp and block the workpiece at the upper ends of the material pushing frame 56 and the movable plate 518, preventing it from falling during pushing, effectively improving the stability of feeding and transportation. And as the material pushing frame 56 continues to move upward, the telescopic push plate 515 continues to push the outer tube 581. When the baffle 584 fits the workpiece, the outer tube 581 starts to compress the first spring 585 and moves into the inner cavity of the fixed cover 583 until it fits one end of the electromagnet 589. The outer tube 581 is a magnetic metal, so it is magnetically fixed to the electromagnet 589. At the same time, the material pushing frame 56 moves upward to a position higher than the concave frame 1 and the back plate 3. The material pushing frame 56 performs a reset and downward movement operation, and the material blocking assembly 58 also moves with it for reset. Then the telescopic push plate 515 drives the outer tube 581 to move in the opposite direction. Since the outer tube 581 is magnetically fixed to the electromagnet 589 outside the inner column 582, the outer tube 581 first drives the electromagnet 589 and the inner column 582 to move in the opposite direction. Then the inner column 582 drives the baffle 584 to leave the surface of the workpiece, facilitating the blanking of the workpiece. Subsequently, the electromagnet 589 is powered off, and the compressed first spring 585 first ejects the inner column 582 away from the outer tube 581 in the opposite direction. As the outer tube 581 then drives the inner column 582 to continue to reset through the first spring 585, it is convenient for the next pushing, limiting, blocking, and clamping operations, effectively improving the use effect. And when the baffle 584 moves into the upper end of the material pushing frame 56 as the inner column moves, the third spring 587 and the arc-shaped pressing column 588 in the inner cavity of the installation groove 586 at the lower end of the baffle 584 move above the movable plate 518. The compressed third spring 587 drives the arc-shaped pressing column 588 to press down the movable plate 518. Since the elastic performance of the second spring 521 is less than that of the third spring 587, the movable plate 518 tilts downward and compresses the second spring 521. Subsequently, when the material pushing frame 56 is reset, the baffle 584 of the material blocking assembly 58 leaves both sides of the workpiece, and the workpiece at the upper ends of the material pushing frame 56 and the movable plate 518 naturally falls along the inclined movable plate 518, facilitating the automatic and stable pushing of materials, effectively improving the use effect.

[0039] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
