Description

Technical Field

[0001] This utility model relates to the field of drilling technology, specifically to a simple vertical bench drill. Background Technology

[0002] A bench drill, or simply bench drill, is a small, easy-to-operate machine tool typically mounted on a dedicated workbench for drilling holes in workpieces. It uses a handle to lower the chuck and drill holes. For example, utility model publication CN220006104U, entitled "A Bench Drill," discloses a bench drill comprising a base, a vertically mounted column, a spindle box, a spindle assembly, and a control device for driving the spindle assembly up and down. The spindle assembly includes a motor mounting plate, a spindle mounting plate, a drive motor, a transmission device, and a spindle. The drive motor is mounted on the motor mounting plate, the spindle is mounted on the spindle mounting plate, and the transmission device is located between the motor shaft and the spindle. The lower end of the spindle protrudes from the spindle box and is fitted with a chuck. The control device includes a control gear inside the spindle box and a control handle outside the spindle box. The control handle drives the control gear to rotate. A control tooth groove is formed on the side of the mounting sleeve, and the control gear meshes with the control tooth groove. Rotation of the control gear drives the spindle assembly up and down. Although it can achieve the purpose of drilling, the chuck can only move up and down in the Z-axis direction, and cannot move in the X and Y axes. This requires frequent adjustment of the workpiece position when machining holes in different locations, which greatly reduces the machining efficiency. Moreover, the operation of the control handle is not convenient. The control handle needs to be turned to control the spindle to move up and down, and sometimes the handle needs to be turned many times. This undoubtedly increases the difficulty and labor intensity of operation for the operator, and affects the smoothness and convenience of the machining process. Utility Model Content

[0019] The lockable X-axis moving mechanism 3 is mounted on the base 1. Specifically, the lockable X-axis moving mechanism 3 includes an X-axis slide rail 31, an X-axis slider 32, an X-axis slide block 33, an X-axis locking seat 34, and an X-axis knurled hand-tightening screw 35. The X-axis slide rail 31 is mounted on the base 1 by screws. The X-axis slider 32 is movably mounted on the X-axis slide rail 31. The X-axis slide block 33 is mounted on the X-axis slider 32 by screws. One end of the X-axis locking seat 34 is fixed to the X-axis slide block 33 by screws, and the other end is provided with an X-axis bow-shaped portion 341 extending to the side of the X-axis slide rail 31. The X-axis bow-shaped portion 341 is provided with an X-axis threaded hole 342 that matches the X-axis knurled hand-tightening screw 35. The X-axis knurled hand-tightening screw 35 is screwed into the X-axis threaded hole 342 and can press against the X-axis slide rail 31 when tightened. The X-axis slider 32 slides on the X-axis slide rail 31, driving the X-axis slide block 33 and the components mounted on it to move along the X-axis direction. The X-axis locking seat 34 abuts against the X-axis slide rail 31 through the X-axis knurled hand screw 35, thereby locking the position in the X-axis direction. When the position needs to be adjusted, loosen the X-axis knurled hand screw 35, move the X-axis slide block 33 to the desired position, and then tighten the screw to lock it. This makes the movement and locking operation in the X-axis direction simple and convenient, without the need for complicated tools. Operators can quickly adjust and fix the position by hand-tightening the screw, improving the convenience of operation and work efficiency.

[0020] The lockable Y-axis moving mechanism 4 is mounted on the lockable X-axis moving mechanism 3. Specifically, the lockable Y-axis moving mechanism 4 includes a Y-axis slide rail 41, a Y-axis slider 42, a Y-axis locking seat 43, and a Y-axis knurled hand-tightening screw 44. The Y-axis slide rail 41 is mounted on the X-axis slide seat 33 by screws. The Y-axis slider 42 is movably mounted on the Y-axis slide rail 41. One end of the Y-axis locking seat 43 is fixed to the lower end of the vertical frame 7 by screws, and the other end has a Y-axis bow-shaped portion 431 extending to the side of the Y-axis slide rail 41. The Y-axis bow-shaped portion 431 has a Y-axis threaded hole 432 that matches the Y-axis knurled hand-tightening screw 44. The Y-axis knurled hand-tightening screw 44 is screwed into the Y-axis threaded hole 432 and presses against the Y-axis slide rail 41 when tightened. The Y-axis slider 42 slides on the Y-axis slide rail 41, driving the vertical frame 7 and the components mounted on it to move along the Y-axis direction. The Y-axis locking seat 43 abuts against the Y-axis slide rail 41 via the Y-axis knurled hand-tightening screw 44, locking the position in the Y-axis direction. When adjustment is needed, loosen the screw, move it to the appropriate position, and then tighten the screw to lock it, realizing convenient movement and locking in the Y-axis direction. In conjunction with the X-axis moving mechanism, it enables the drilling head 2 to perform drilling operations at any position on the horizontal plane, further improving the flexibility and adaptability of the equipment.

[0021] The vertical frame 7 is mounted on the lockable Y-axis moving mechanism 4, and the hand-operated frame 6 is mounted on the vertical frame 7 via a movable Z-axis moving mechanism 5.

The Z-axis slide rail 51 is screwed onto the front of the vertical frame 7, and the Z-axis slider 52 is movably mounted on the Z-axis slide rail 51. When the Z-axis slider 52 slides on the Z-axis slide rail 51, the drilling head 2 moves up and down along the Z-axis, thereby adjusting the drilling depth. The drilling depth can be controlled through a simple sliding operation.

[0022] The drilling head 2 is mounted on the hand-operated frame 6. One end of the air spring 8 rests against the vertical frame 7, and the other end rests against the hand-operated frame 6. In this embodiment, the air spring 8 is preferably a nitrogen spring. Nitrogen springs utilize high-pressure nitrogen as the elastic medium, providing more stable and predictable elasticity and support compared to ordinary air springs 8. Specifically, the hand-operated frame 6 includes an L-shaped bracket 61, a handle 62, and a spring fixing seat 63. The vertical portion of the L-shaped bracket 61 is screwed onto the Z-axis slider 52, and the horizontal portion of the L-shaped bracket 61 provides a mounting and support platform for the drilling head 2. The horizontal portion of the L-shaped bracket 61 has a through-hole for the air spring 8 to pass through. The spring fixing seat 63 is screwed onto the horizontal portion corresponding to the through-hole, providing reliable mounting and support for the air spring 8. The upper end of the air spring 8 passes through the through-hole and is mounted on the spring fixing seat 63. The handle 62 is mounted on the horizontal part of the L-shaped bracket 61. The handle 62 is used by the operator to apply force to push the hand press frame 6 up and down, thereby improving the comfort and convenience of operation.

[0023] The drilling head 2 includes a motor 21, a bearing housing 22, a spindle 23, and a chuck 24. The upper end of the spindle 23 is mounted on the hand-operated frame 6 via the bearing housing 22, which provides stable support for the spindle 23, ensuring its concentricity and stability during rotation. The chuck 24 is located at the lower end of the spindle 23 and is used to clamp drill bits, allowing for easy replacement of drill bits of different specifications. The motor 21 is mounted on the hand-operated frame 6 and drives the spindle 23 to rotate via a transmission assembly. In this embodiment, the transmission assembly is a belt drive; in other embodiments, it can also be a chain drive or gear drive, etc. The spindle 23 drives the chuck 24 and the drill bit mounted on it to rotate.

[0024] During operation, the vertical frame 7 can be moved along the X-axis and Y-axis directions in the horizontal plane via the lockable X-axis moving mechanism 3 and the lockable Y-axis moving mechanism 4, respectively. This allows the drilling head 2 to be precisely positioned on the horizontal plane, facilitating rapid drilling at different positions on the workpiece. Furthermore, the X-axis and Y-axis coordinates can be locked using the X-axis knurled hand screw 35 and the Y-axis knurled hand screw 44. Applying a downward force to the handle 62 moves the drilling head 2 downwards to achieve the drilling purpose. Simultaneously, the height of the drilling head 2 can be flexibly adjusted by releasing the handle 62, enabling flexible control of the drilling depth. The operation is simple and convenient.
