Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to a high-stability radial drilling machine. Background Art

[0002] A radial drilling machine is a drilling machine with a rocker arm that can rotate and rise and fall around a column, and usually the spindle box moves horizontally on the rocker arm. This type of drilling machine is often used for hole processing, including drilling, expanding, reaming, tapping, and scraping end faces. A radial drilling machine usually includes components such as a column, a rocker arm, a base, a workbench, and a spindle box.

[0003] The workbench of some existing radial drilling machines is movable. The movable workbench expands the working range and effectively improves work efficiency. However, the movable workbench is generally fixed by friction using bolts against the base. When the workpiece is mounted on the workbench for drilling, vibration will occur. The vibration will cause the workbench to shift, resulting in poor stability and affecting the drilling effect. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 5The utility model provides a technical solution: a high-stability radial drilling machine, comprising a base 1, a column 2 fixedly mounted on the base 1, a rocker 4 rotatably mounted on the column 2, a spindle box 3 slidably mounted on the rocker 4, and a workbench 5 arranged on the base 1, a plurality of T-shaped slots 6 are opened on the base 1, a plurality of card slots 7 are also arranged inside the base 1, and the plurality of card slots 7 are connected with adjacent T-shaped slots 6, a screw 11 is threadedly connected to the workbench 5, the screw 11 is rotated to move the screw 11 downward, the screw 11 moves the slider 10 downward through the limit plate 13, the slider 10 drives the card block 9 to move downward, the card block 9 is stuck in the card slot 7, so as to fix the workbench 5, a limit plate 13 is provided at the bottom of the screw 11, the screw 11 can drive the slider 10 to move longitudinally through the limit plate 13, And when the screw rod 11 drives the limit plate 13 to rotate, the limit plate 13 will not drive the slider 10 to rotate. A slider 10 is provided on the outer side of the limit plate 13, and the slider 10 is slidably connected to the workbench 5. One end of the slider 10 is integrally formed with a block 9 that matches the slot 7. The block 9 is inserted into the slot 7 to fix the workbench 5. Compared with the original method of using bolts to tighten the base 1 to fix the workbench 5 through friction, the block 9 is inserted into the slot 7 to directly prevent the workbench 5 from moving laterally, and the fixing effect is better. Even if it is subjected to the vibration generated during drilling, it can still play a good fixing role on the workbench 5, making the workbench 5 more stable and avoiding deviation during drilling. A knob 12 is provided at the end of the screw rod 11 away from the limit plate 13, and the knob 12 is convenient for the user to rotate the screw 11.

[0019] Among them, the bottom of the workbench 5 is fixedly connected with a T-shaped block 8 which is slidably connected to the T-shaped slot 6. The cooperation between the T-shaped block 8 and the T-shaped slot 6 makes the workbench 5 more stable when sliding, and due to the limitations of the T-shaped block 8 and the T-shaped slot 6, the workbench 5 cannot undergo longitudinal displacement, so as to facilitate the fixation of the workbench 5.

[0020] Among them, the top of the slider 10 is provided with an avoidance hole 14, which is used to avoid the screw 11. The inside of the slider 10 is provided with a rotating hole 15 that cooperates with the limit plate 13. The limit plate 13 can rotate in the rotating hole 15, and the rotating hole 15 is connected to the avoidance hole 14.

[0021] The diameter of the avoidance hole 14 is larger than the diameter of the screw rod 11 , so that the screw rod 11 will not affect the slider 10 when rotating.

[0022] The width of the slider 10 is smaller than the width of the notch of the T-slot 6 , so as to prevent the slider 10 from being blocked by the T-slot 6 and unable to move.

[0023] When the workbench 5 is in a suitable position, the knob 12 is turned to rotate the screw rod 11, and the screw rod 11 rotates and moves downward, and the screw rod 11 drives the limit plate 13 to move downward, and the limit plate 13 causes the slider 10 to move downward, and the slider 10 causes the block 9 to move downward, and the block 9 is stuck in the slot 7 until the slider 10 is blocked by the base 1 and cannot move, resulting in the knob 12 being unable to rotate. At this time, the block 9 cooperates with the slot 7 to prevent the base 1 from lateral displacement, and the T-shaped block 8 cooperates with the T-shaped slot 6 to prevent the base 1 from longitudinal displacement, thereby fixing the workbench 5. Even if it is subjected to vibration during drilling, the workbench 5 can still maintain high stability to ensure the drilling effect. When the position of the workbench 5 needs to be adjusted again, the knob 12 is turned to make the screw rod 11 move upward, and the screw rod 11 moves the slider 10 upward through the limit plate 13, and the slider 10 causes the block 9 to move upward. When the block 9 falls off the slot 7, the position of the workbench 5 can be adjusted again.
