Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a clamping device for a bench drill. Background Technique

[0002] A bench drill is abbreviated as a bench drill. A bench drill is a small drill press that can be placed on a workbench. The diameter of the bench drill hole is generally between 13 mm and 25 mm, and it is manually operated. A clamping device for a bench drill is a device used to clamp a workpiece on a bench drill. Its main purpose is to stably fix the workpiece in place during the bench drill processing, reduce vibration, and improve machining accuracy.

[0003] However, the traditional clamping device does not have the functions of angle and position adjustment. When in use, the user can only fix the workpiece to be processed in a certain position and cannot adjust the angle and position as needed, resulting in the phenomenon that the entire fixing component has to be moved, reducing work efficiency. Moreover, the traditional clamping device lacks a limiting function. When in use, after the workpiece to be processed is clamped and fixed, if the drill bit drills through the workpiece, it cannot stop in time, which may damage the base of the clamping device, resulting in the phenomenon of reducing the service life of the overall clamping device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a clamping device for a bench drill to solve the problems raised in the above background technique.

[0024] In this embodiment, through the arrangement of the electric telescopic rod 4 and the connecting rod 5, when in use, the length of the electric telescopic rod 4 is adjusted, so that the electric telescopic rod 4 drives the top connecting rod 5 to move. The first bottom plate 2 is rotatably connected to the top of the connecting rod 5 through a rotating shaft, thereby achieving the effect of adjusting the angle of the first bottom plate 2. Through the arrangement of the first threaded rod 8, the first slider 9, the second bottom plate 10, the third installation groove 12, the second threaded rod 13 and the second slider 14, when in use, the first threaded rod 8 is rotated, the first slider 9 moves along the surface of the first threaded rod 8, driving the top clamping component to move left and right.

[0029] Working principle: Through the setting of the electric telescopic rod 4 and the connecting rod 5, during use, the length of the electric telescopic rod 4 is adjusted, causing the electric telescopic rod 4 to drive the top connecting rod 5 to move. The first base plate 2 is rotatably connected to the top of the connecting rod 5 through a rotating shaft, thereby achieving the effect of adjusting the angle of the first base plate 2. Through the setting of the first threaded rod 8, the first slider 9, the second base plate 10, the third installation groove 12, the second threaded rod 13, and the second slider 14, during use, the first threaded rod 8 is rotated, and the first slider 9 moves along the surface of the first threaded rod 8, driving the top clamping assembly to move left and right. The second threaded rod 13 is rotated, and the second slider 14 moves along the surface of the second threaded rod 13, driving the top clamping assembly to move back and forth. Moreover, both sides of the first slider 9 and the second slider 14 are closely attached to the inner surfaces of the second installation groove 7 and the third installation groove 12, preventing the first slider 9 and the second slider 14 from rotating synchronously with the first threaded rod 8 and the second threaded rod 13, thereby achieving the effect of facilitating the control of the drilling position and angle of the workpiece clamped at the top of the overall device. At the same time, through the setting of the bidirectional threaded rod 17, the third slider 18, the baffle 19, the strip plate 20, and the first rotating block 21, when it is necessary to clamp the workpiece for processing, the workpiece for processing is placed on the top of the strip plate 20, and then the first rotating block 21 is rotated. The first rotating block 21 drives the bidirectional threaded rod 17 to rotate, and the third sliders 18 on the surface of the bidirectional threaded rod 17 move relatively, causing the baffles 19 at the tops of the third sliders 18 to respectively abut against both sides of the workpiece for processing. Both sides of the third slider 18 are closely attached to the fourth installation groove 16, preventing the third slider 18 from rotating synchronously with the threaded rod. And through the strip plate 20, the middle of the bottom of the workpiece for processing is hollowed out, thereby achieving the effect of avoiding damage to the surface of the fixed plate 15 when the drill bit passes through the workpiece for processing during the drilling process while clamping the workpiece for processing. Through the second rotating block 22 and the third rotating block 23, during use, the second rotating block 22 and the third rotating block 23 are rotated, and by controlling the rotation direction, the effect of adjusting the moving direction of the first slider 9 and the second slider 14 is achieved. Through the setting of the limiting block 25, the moving plate 26, the screw rod 27, the fourth rotating block 28, and the pressing plate 29, during use, the moving plate 26 is pushed, driving the limiting block 25 to slide inside the limiting groove 24, controlling the screw rod 27 inside the moving plate 26 to move along one side of the baffle 19. When it moves to the appropriate position, the fourth rotating block 28 is rotated, driving the screw rod 27 to rotate, and controlling the pressing plate 29 at the bottom of the screw rod 27 to abut against both sides of the top of the workpiece for processing, thereby achieving the effect of preventing the workpiece for processing from shaking during the fixing and processing process. Through the setting of the connecting block 30, during use, the fixing bolt 31 is passed through the connecting block 30 and fixedly connected to an external device, thereby achieving the effect of facilitating the fixation of the overall device.
