[0002] A bench drill, or simply bench drill, is a small drilling machine that can be placed on a worktable with a vertically arranged spindle. Bench drills typically drill holes with a diameter of 13 mm or less, generally not exceeding 25 mm. Spindle speed is usually changed by altering the position of the V-belt on the pulley. Spindle feed is manually operated, and the system needs to be adjusted and secured during use.

[0003] Existing bench drill fastening and adjustment devices are not easy to adjust and fix in a convenient manner, which may reduce the adaptability of the device. Existing bench drill fastening and adjustment devices are not easy to effectively limit and reset the drill bit, which may reduce the stability and adaptability of the device.

[0004] Therefore, a bench drill fastening and adjustment device is proposed to address the above problems. Utility Model Content

[0005] To address the problems in the existing technology, this utility model proposes a bench drill fastening and adjustment device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The bench drill fastening and adjustment device of this utility model includes a base plate, a support column fixedly connected to the surface of the base plate, a clamping ring snapped onto the surface of the support column, a platform fixedly connected to one side of the clamping ring, a threaded rocker arm penetrating the surface of the clamping ring, a nut fixedly connected to the surface of the clamping ring, a mounting bracket fixedly connected to the top of the support column, a connecting rod rotatably connected to the bottom of the mounting bracket, a sleeve slidably connected to the surface of the connecting rod, a drill bit fixedly connected to the bottom of the sleeve, and a housing rotatably connected to the surface of the sleeve.

[0007] Preferably, the inner wall of the clamping ring is slidably connected to the surface of the support column, and the internal thread of the nut is fitted with a threaded rocker arm.

[0008] Preferably, a sliding column is fixedly connected inside the mounting bracket, and the surface of the sliding column is slidably connected to one side of the housing.

[0009] Preferably, a spring is slidably sleeved on the surface of the sliding column near the lower part of the housing, and the surface of the housing is slidably connected to the inner wall of the mounting bracket.

[0010] Preferably, the mounting bracket is internally rotatably connected to a gear rocker arm, the surface of which meshes with the surface of the connecting sleeve.

[0011] Preferably, a motor is fixedly connected to the top of the mounting bracket, and the output end of the motor passes through the interior of the mounting bracket and is fixedly connected to the top of the connecting rod.

[0012] The advantages of this utility model are:

[0013] 1. This utility model achieves the effect of adjusting the position of the device and fixing it by sliding the clamping ring to a suitable position on the surface of the support column and rotating the threaded rocker. Since the nut is fixed on one side of the clamping ring, the other side of the clamping ring is squeezed inward, so that the clamping ring is fixed to the surface of the support column, which facilitates the adjustment of the device position and the fixing effect, and improves the adaptability of the device.

[0014] 2. This utility model uses a gear rocker arm inside the mounting frame to rotate, causing the sleeve engaged with the gear rocker arm to descend. The sleeve slides and connects with the surface of the sliding column and the inner wall of the mounting frame. After the sleeve moves the tube down, the motor drives the tube to rotate through the connecting rod, which drives the drill bit to work. After the processing is completed and the gear rocker arm is released, the two ends of the spring support the sleeve and the mounting frame respectively, causing the sleeve to rise and reset, thus improving the stability and adaptability of the device.

[0022] Please see Figures 1-4 As shown, a bench drill fastening and adjustment device includes a base plate 1, a support column 2 fixedly connected to the surface of the base plate 1, a clamping ring 3 snapped onto the surface of the support column 2, a platform 4 fixedly connected to one side of the clamping ring 3, a threaded rocker arm 5 extending through the surface of the clamping ring 3, a nut 6 fixedly connected to the surface of the clamping ring 3, a mounting bracket 7 fixedly connected to the top of the support column 2, a connecting rod 9 rotatably connected to the bottom of the mounting bracket 7, a sleeve 10 slidably connected to the surface of the connecting rod 9, a drill bit 11 fixedly connected to the bottom of the sleeve 10, and a housing 12 rotatably connected to the surface of the sleeve 10.

[0023] Furthermore, the inner wall of the clamping ring 3 is slidably connected to the surface of the support column 2, and the internal thread of the nut 6 is fitted with a threaded rocker arm 5;

[0024] During operation, the structure design of the clamping ring 3 slidingly connected to the surface of the support column 2 through the inner wall of the clamping ring 3 makes it easy to adjust the clamping ring 3 to a suitable position.

[0025] Furthermore, a sliding column 14 is fixedly connected inside the mounting bracket 7, and the surface of the sliding column 14 is slidably connected to one side of the housing 12;

[0026] During operation, the sliding column 14 is slidably connected to one side of the housing 12 through the structural design, which limits the movement of the housing 12 and improves the stability of the housing 12.

[0027] Furthermore, a spring 15 is slidably sleeved on the surface of the sliding column 14 near the lower part of the housing 12, and the surface of the housing 12 is slidably connected to the inner wall of the mounting bracket 7.

[0028] During operation, the spring 15 is slidably connected to the surface of the sliding column 14 near the lower part of the housing 12. The spring 15 provides support for the housing 12 and the mounting bracket 7, giving the housing 12 a tendency to slide upward and return to its original position.

[0029] Furthermore, a gear rocker arm 13 is rotatably connected inside the mounting bracket 7, and the surface of the gear rocker arm 13 meshes with the surface of the housing 12;

[0030] During operation, the gear rocker arm 13 engages with the surface of the housing 12 through a structural design that allows for easy adjustment of the position of the housing 12 when the gear rocker arm 13 is rotated.

[0031] Furthermore, a motor 8 is fixedly connected to the top of the mounting frame 7, and the output end of the motor 8 passes through the interior of the mounting frame 7 and is fixedly connected to the top of the connecting rod 9;

[0032] During operation, the motor 8, which is fixedly connected to the top of the mounting frame 7, drives the connecting rod 9 to rotate. The motor 8 drives the sleeve 10 and the drill bit 11 to rotate through the connecting rod 9, thereby increasing the working range of the device.

[0033] Working principle: First, slide the clamping ring 3 to a suitable position on the surface of the support column 2, rotate the threaded rocker arm 5. Since the nut 6 is fixed on one side of the clamping ring 3, the other side of the clamping ring 3 is squeezed inward, so that the clamping ring 3 is fixed to the surface of the support column 2. At this time, rotate the gear rocker arm 13 inside the mounting bracket 7. The sleeve 12, which meshes with the gear rocker arm 13, descends. The sleeve 12 slides through the surface of the sliding column 14 and the inner wall of the mounting bracket 7, which improves the stability of the sleeve 12 during movement. After the sleeve 12 drives the sleeve 10 to descend, the motor 8 drives the sleeve 10 to rotate through the connecting rod 9, which drives the drill bit 11 to work. After the processing is completed, release the gear rocker arm 13. The two ends of the spring 15 support the sleeve 12 and the mounting bracket 7 respectively, so that the sleeve 12 rises and returns to its original position.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
