Description

Technical Field

[0001] This utility model relates to the field of steel bar chamfering technology, and in particular to a steel bar chamfering device. Background Technology

[0002] For example, the high-efficiency steel bar chamfering equipment disclosed on the Chinese Patent Network (application number: 201921667160.6) facilitates faster steel bar chamfering by simultaneously chamfering multiple steel bars, which is more efficient than chamfering a single steel bar in the prior art. Although this improves efficiency, it requires setting up multiple chamfering mechanisms, which consumes more resources. Secondly, the entire operation lacks continuity, and it still takes time to replace multiple steel bars, affecting work efficiency. Utility Model Content

[0003] To address the technical problems of existing steel bar chamfering mechanisms consuming excessive resources and requiring time for steel bar replacement, this utility model proposes a steel bar chamfering device.

[0004] This utility model discloses a steel bar chamfering device, including a worktable. A control mechanism is provided above the worktable. The control mechanism includes a drive motor, a control rod, a swing rod, a connecting rod, a moving plate, a lifting rod, and an electric gripper. When the drive motor is started, the rotating shaft drives the control rod to rotate. The control rod drives the swing rod and the connecting rod to swing. The connecting rod drives the moving plate to move horizontally. The lifting rod drives the electric gripper to move up and down.

[0005] Preferably, the upper surface of the workbench is fixedly mounted with a mounting column and a mounting bracket, the drive motor is fixedly mounted on the upper surface of the mounting column, the control rod is fixedly connected to the rotating shaft of the drive motor, the outer surface of the control rod is rotatably connected to the interior of the mounting column, and the swing rod is fixedly mounted on the outer surface of the control rod.

[0006] With the above technical solution, when the drive motor starts, the rotating shaft drives the control rod to rotate, and the control rod drives the swing rod to swing.

[0007] Preferably, a fixed round rod is fixedly installed on the upper side surface of the swing rod, the connecting rod is rotatably connected to the outer surface of the fixed round rod, the movable plate is slidably connected to the outer surface of the mounting frame, a connecting piece is fixedly installed on the left side surface of the movable plate, and a mounting rod is fixedly installed on the inner side surface of the connecting piece.

[0008] With the above technical solution, when the swing rod swings, the fixed round rod drives the connecting rod to swing, and the moving plate moves horizontally outside the mounting frame.

[0009] Preferably, the inner end of the connecting rod is rotatably connected to the outer surface of the mounting rod, the inner surface of the movable plate is provided with an inclined groove, the inner surface of the mounting frame is provided with a bending groove, a sliding plate is slidably inserted into the inner surface of the bending groove, a limiting plate is fixedly installed on the front end surface of the sliding plate, and the outer surface of the limiting plate is slidably connected to the outer surface of the mounting frame.

[0010] With the above technical solution, when the connecting rod swings, it drives the mounting rod, which in turn causes the connecting piece to move the moving plate, and the limiting plate ensures that the sliding plate is stuck in the bending groove.

[0011] Preferably, a connecting rod is fixedly installed on the rear end surface of the slide plate, the outer surface of the connecting rod is slidably connected to the inside of the inclined groove, a crossbar is fixedly installed on the outer surface of the connecting rod, the lifting rod is fixedly installed inside the crossbar, the electric gripper is fixedly installed on the lower surface of the lifting rod, and a control switch is fixedly installed inside the bending groove. The control switch is electrically connected to the electric gripper through a wire.

[0012] With the above technical solution, the connecting rod slides in the inclined groove, driving the crossbar and lifting rod to move. When the slide plate moves to the rightmost end of the bending groove, it presses the control switch, causing the control switch to start the electric gripper, so that the electric gripper opens and then closes to clamp the steel bar that needs to be chamfered.

[0013] Preferably, a sliding plate is slidably inserted into the inside of the workbench, a clamping plate is fixedly installed on the outer surface of the rear end of the sliding plate, a spring is fixedly installed on the outer surface of the front end of the sliding plate, the other end of the spring is fixedly connected to the inside of the workbench, a chamfering groove is provided at the bottom of the workbench, and a chamfering mechanism is fixedly installed inside the chamfering groove.

[0014] Through the above technical solution, the spring squeezes the sliding plate, causing the clamping plate to hold the steel rod. The steel rod is inserted into the chamfering groove, allowing the chamfering mechanism to chamfer the steel rod. The cutting tool on the chamfering mechanism can chamfer the steel rod.

[0015] The beneficial effects of this utility model are as follows:

[0016] By setting up a control mechanism, when the steel bar is chamfered, the drive motor is started, causing the control lever to swing the swinging rod, which in turn swings the connecting rod. The connecting rod then moves the connecting piece and the moving plate horizontally within the mounting frame. At this time, the sliding plate moves within the bending groove. As the moving plate continues to move to the left within the mounting frame, the inclined groove squeezes the connecting rod, causing it to move along the inclined groove. This allows the sliding plate to move downwards in the vertical direction of the bending groove, which in turn moves the lifting rod, crossbar, electric gripper, and steel bar downwards, inserting the steel bar into the chamfering groove so that the chamfering mechanism can chamfer the steel bar. As the control lever continues to rotate, the connecting rod swings continuously, causing the moving plate to move back and forth horizontally. When the slide moves to the rightmost end of the bending groove, the control switch is pressed, which activates the electric gripper. The electric gripper first opens and then closes to clamp the steel bar that needs to be chamfered. The clamping force of the clamping plates is less than the friction between the electric gripper and the steel bar, allowing the electric gripper to lift the steel bar away from between the clamping plates. Then, it moves to the left to complete the chamfering. During the chamfering process, the worker gently pushes and holds the steel bar placed between the two clamping plates, so that the electric gripper can clamp the first steel bar when clamping the next steel bar. The previously chamfered steel bar is released when the electric gripper is released and falls from the workbench, achieving the effect of saving resources and saving time on steel bar replacement.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 A steel bar chamfering device includes a worktable 1. To facilitate clamping the steel bar, a control mechanism is provided above the worktable 1. The control mechanism includes a drive motor 2, a control rod 3, a swing rod 4, a connecting rod 5, a moving plate 6, a lifting rod 7, and an electric gripper 8. When the drive motor 2 starts, the rotating shaft drives the control rod 3 to rotate. The control rod 3 drives the swing rod 4 and the connecting rod 5 to swing. The connecting rod 5 drives the moving plate 6 to move horizontally. The lifting rod 7 drives the electric gripper 8 to move up and down.

[0025] To facilitate the control of the swing arm 4 by the drive motor 2, the upper surface of the worktable 1 is fixedly equipped with a mounting column 11 and a mounting bracket 12. The drive motor 2 is fixedly installed on the upper surface of the mounting column 11, and the control rod 3 is fixedly connected to the rotating shaft of the drive motor 2. The outer surface of the control rod 3 is rotatably connected to the inside of the mounting column 11. The swing arm 4 is fixedly installed on the outer surface of the control rod 3. When the drive motor 2 starts, the rotating shaft drives the control rod 3 to rotate, and the control rod 3 drives the swing arm 4 to swing.

[0026] To facilitate the horizontal movement of the movable plate 6 outside the mounting frame 12, a fixed round rod 41 is fixedly installed on the upper side surface of the swing rod 4. The connecting rod 5 is rotatably connected to the outer surface of the fixed round rod 41. The movable plate 6 is slidably connected to the outer surface of the mounting frame 12. A connecting piece 61 is fixedly installed on the left side surface of the movable plate 6. An installation rod 62 is fixedly installed on the inner side surface of the connecting piece 61. When the swing rod 4 swings, the fixed round rod 41 drives the connecting rod 5 to swing, and the movable plate 6 moves horizontally outside the mounting frame 12.

[0027] To ensure that the slide plate 14 moves within the bending groove 13, the inner end of the connecting rod 5 is rotatably connected to the outer surface of the mounting rod 62. The moving plate 6 has an inclined groove 63 inside, and the mounting frame 12 has a bending groove 13 inside. The slide plate 14 is slidably inserted into the bending groove 13. A limiting plate 15 is fixedly installed on the front surface of the slide plate 14. The outer surface of the limiting plate 15 is slidably connected to the outer surface of the mounting frame 12. When the connecting rod 5 swings, it drives the mounting rod 62, which in turn causes the connecting piece 61 to move the moving plate 6. The limiting plate 15 ensures that the slide plate 14 moves within the bending groove 13.

[0028] To facilitate clamping the steel bar, a connecting rod 16 is fixedly installed on the rear end surface of the slide plate 14. The outer surface of the connecting rod 16 is slidably connected to the inside of the inclined groove 63. A crossbar 17 is fixedly installed on the outer surface of the connecting rod 16. A lifting rod 7 is fixedly installed inside the crossbar 17. An electric gripper 8 is fixedly installed on the lower surface of the lifting rod 7. A control switch 131 is fixedly installed inside the bending groove 13. The control switch 131 is electrically connected to the electric gripper 8 through a wire. The connecting rod 16 slides in the inclined groove 63, driving the crossbar 17 and the lifting rod 7 to move. When the slide plate 14 moves to the rightmost end of the bending groove 13, it squeezes the control switch 131, causing the control switch 131 to control the electric gripper 8 to start, so that the electric gripper 8 first opens and then closes to clamp the steel bar that needs to be chamfered.

[0029] To facilitate the chamfering mechanism 112 in chamfering the steel bar, a sliding plate 18 is slidably inserted into the inside of the worktable 1. A clamping plate 19 is fixedly installed on the outer surface of the rear end of the sliding plate 18, and a spring 110 is fixedly installed on the outer surface of the front end of the sliding plate 18. The other end of the spring 110 is fixedly connected to the inside of the worktable 1. A chamfering groove 111 is provided at the bottom of the worktable 1. The chamfering mechanism 112 is fixedly installed inside the chamfering groove 111. The spring 110 presses the sliding plate 18, causing the clamping plate 19 to clamp the steel bar. The steel bar is inserted into the chamfering groove 111, allowing the chamfering mechanism 112 to chamfer the steel bar. The cutting tool on the chamfering mechanism 112 can chamfer the steel bar.

[0030] By setting up a control mechanism, when the steel bar is chamfered, the drive motor 2 is started, causing the control lever 3 to drive the swing lever 4 to swing. The swing lever 4 drives the connecting rod 5 to swing, and the connecting rod 5 drives the connecting piece 61 and the moving plate 6 to move horizontally within the mounting frame 12. At this time, the sliding plate 14 moves within the bending groove 13. As the moving plate 6 continues to move to the left within the mounting frame 12, the inclined groove 63 squeezes the connecting round rod 16, causing the connecting round rod 16 to move along the inclined groove 63. This allows the sliding plate 14 to move downwards in the vertical direction of the bending groove 13, thereby driving the lifting rod 7, the crossbar 17, the electric gripper 8, and the steel bar to move downwards, inserting the steel bar into the chamfering groove 111 so that the chamfering mechanism 112 can chamfer the steel bar. As the control lever 3 continues to rotate, the connecting rod 5 swings continuously, which will drive... The movable plate 6 moves horizontally back and forth. When the slide plate 14 moves to the rightmost end of the bending groove 13, it presses the control switch 131, causing the control switch 131 to activate the electric gripper 8. The electric gripper 8 first opens and then closes to clamp the steel bar that needs to be chamfered. The clamping force of the clamping plate 19 is less than the friction between the electric gripper 8 and the steel bar, allowing the electric gripper 8 to carry the steel bar away from between the clamping plates 19. Then, it moves to the left to complete the chamfering. During the chamfering process, the worker gently pushes and holds the steel bar placed between the two clamping plates 19, so that the electric gripper 8 can clamp the first steel bar when clamping the next steel bar. The previously chamfered steel bar is released when the electric gripper 8 is released and falls from the workbench 1, achieving the effect of saving resources and saving time on steel bar replacement.

[0031] Working principle: When chamfering the steel bar, the drive motor 2 is started, causing the control lever 3 to drive the swing lever 4 to swing. The swing lever 4 drives the connecting rod 5 to swing. The connecting rod 5 drives the connecting piece 61 and the moving plate 6 to move horizontally within the mounting frame 12. At this time, the sliding plate 14 moves within the bending groove 13. As the moving plate 6 continues to move to the left within the mounting frame 12, the inclined groove 63 squeezes the connecting round rod 16, causing the connecting round rod 16 to move along the inclined groove 63. This allows the sliding plate 14 to move downwards in the vertical direction of the bending groove 13, thereby driving the lifting rod 7, the crossbar 17, the electric gripper 8, and the steel bar to move downwards, inserting the steel bar into the chamfering groove 111 so that the chamfering mechanism 112 chamfers the steel bar. As the control lever 3 continues to rotate, the connecting rod 5... The continuous swinging motion causes the moving plate 6 to move horizontally back and forth. When the sliding plate 14 moves to the rightmost end of the bending groove 13, it presses the control switch 131, causing the control switch 131 to activate the electric gripper 8. The electric gripper 8 first opens and then closes to clamp the steel bar that needs to be chamfered. The clamping force of the clamping plate 19 is less than the friction between the electric gripper 8 and the steel bar, allowing the electric gripper 8 to carry the steel bar away from between the clamping plates 19. Then, it moves to the left to complete the chamfering. During the chamfering process, the worker gently pushes and holds the steel bar placed between the two clamping plates 19, so that the electric gripper 8 can clamp the first steel bar when clamping the next steel bar. The previously chamfered steel bar is released when the electric gripper 8 is released and falls from the workbench 1.
