Description

Technical Field

[0001] This invention relates to a fully automatic CNC drilling machine in the shape of an eight, which can be used to drill very precise holes or eight-shaped holes in buildings. Background Technology

[0002] In recent decades, housing and construction have developed rapidly. Over time, due to reasons such as foundations and pile foundations, many buildings have become tilted and need to be corrected. Some buildings also need to be expanded by adding floors to meet the needs of users due to space utilization issues. For construction projects such as jacking for correction and adding floors, Wuhan Jucheng Structure Co., Ltd. has proposed a steel sliding track jacking construction method. This method involves first cutting the building columns, and then using jacks to lift the columns according to the actual building conditions. This jacking can correct the building's deviation or raise it by one or more floors. A crucial step in the steel sliding track jacking construction method is transferring the load of the building columns to the shear keys in the jacking brackets, using shear keys that traverse the columns. However, this method requires a very good fit between the shear keys and the building columns. Traditional drilling methods involve manual hand-held water drills, which are labor-intensive, and the drilling quality is highly dependent on the operator's skill. Problems such as drilling deviation and inaccurate positioning also exist. When the shear keys bear the weight of the building, poor drilling quality can easily cause the columns to break, leading to safety malfunctions. Summary of the Invention

[0003] In view of this, the present invention proposes an eight-shaped fully automatic CNC drilling machine, which can perform high-precision automatic drilling on buildings. The machine can automatically drill holes, avoiding the need for manual support of the water drill, and the drilled holes have the characteristics of high precision, high levelness, and high positioning accuracy.

[0004] The technical solution of the present invention is implemented as follows: an eight-shaped fully automatic CNC drilling machine, including a water drill, an upper frame, an automatic feed mechanism, a lower frame, an automatic leveling mechanism, and an automatic lifting device.

[0005] The water drill is a standard construction device, installed on the tray of the automatic feed mechanism.

[0006] The upper frame is designed as a frame structure with four vertical guide rails. The vertical guide rails are inserted into the lower frame columns and can slide up and down along the lower frame columns. The upper frame is equipped with two sets of return pulleys.

[0007] The automatic feed mechanism is installed on the upper frame and is equipped with a feed mechanism tray. The feed mechanism tray is connected and fixed to the water drill and the linear bearing respectively. The linear bearing can slide back and forth along the linear guide rail. A cylinder is provided, and the cylinder is connected to the automatic feed mechanism tray by a steel wire rope.

[0008] The lower frame is a frame structure with columns at each of the four corners and casters at the bottom.

[0009] The automatic leveling mechanism is installed on the lower frame and is driven by a servo motor. There are four of them, and each automatic leveling mechanism is equipped with a horizontal tilt sensor.

[0010] The automatic lifting device is driven by a motor and is connected to the upper and lower frames respectively. There are four of them. When it rises, it pushes the upper frame to move upward. When it falls, it pulls the upper frame to move downward. The upper frame is equipped with a displacement sensor to automatically monitor the lifting height of the upper frame.

[0011] Based on the above technical solution, preferably, the water drill is mounted and fixed to the feed mechanism tray of the automatic feed mechanism. Linear bearings are connected to the four corners of the feed mechanism tray, and these bearings are mounted on linear guide rails. Pushing the water drill allows it to slide back and forth along the linear guide rails. The cylinder is fixed to the upper frame, and the cylinder piston rod is fitted with a pulley system. One end of the feed wire rope is fixed to the upper frame, and the other end passes over the pulley system and is fixed to the feed mechanism tray. One end of the retraction wire rope is fixed to the upper frame, and the other end is secured to the feed mechanism tray via two sets of pulley systems, passing through front and rear fixed pulleys. At this point, the pulley system fitted to the cylinder piston rod forms a movable pulley. The feed speed of the water drill is the extension speed of the cylinder piston rod, and the retraction speed of the water drill is twice the retraction speed of the cylinder piston rod. Because the air pressure is constant, this solution ensures that the feed force of the cylinder is constant, effectively preventing tool jamming.

[0012] Furthermore, the preferred upper frame design is a frame structure with vertical guide rails inserted into the lower frame columns, ensuring a high-precision fit. This allows the upper frame to slide up and down along the lower frame columns. The lower frame is equipped with an automatic leveling device, consisting of four leveling mechanisms driven by servo motors. Each automatic leveling mechanism of the upper frame is equipped with a horizontal tilt sensor. When the automatic lifting device extends, it pushes the upper frame upward along the columns; when the automatic lifting device retracts, it pulls the upper frame downward along the columns. Through the combined adjustment of the servo motors and the horizontal tilt sensors, the upper frame is brought to a horizontal position.

[0013] Furthermore, the lower frame is preferably equipped with rollers at the bottom, allowing the entire machine to move under the action of the rollers. Four sets of automatic lifting devices are installed at the bottom of the lower frame. The automatic lifting devices are driven by servo motors and designed as threaded screws, which are respectively connected to and fixed to the upper and lower frames. Displacement sensors are installed, and the displacement sensors work in conjunction with the lifting servo motors to automatically adjust the lifting height of the upper frame.

[0014] The present invention has the following advantages over the prior art:

[0015] This invention discloses a figure-eight shaped fully automatic CNC drilling machine. The drilling machine utilizes rollers to push the machine into the drilling position. An automatic leveling device raises and lowers the rollers, suspending them in the air. Simultaneously, a horizontal tilt sensor automatically levels the entire machine. The water drill is then activated. Working gas supplied by an electrically controlled air source enters the rodless chamber of the cylinder via a pneumatic-electric reversing valve, causing the cylinder to extend. Because the cylinder head has a movable pulley device, the water drill can feed at twice the cylinder's extension speed, automatically drilling the first high-precision hole. The working gas supplied by the air source can then enter the rod chamber of the cylinder via the pneumatic-electric reversing valve, causing the cylinder to retract. Again, because the cylinder head has a movable pulley device, the water drill can retract at twice the cylinder's extension speed. After retraction, an automatic lifting device precisely and automatically raises the upper frame to the second drilling point, repeating the first drilling process to complete the construction of the second high-precision hole. The operating steps of this device are as follows:

[0016] S1: The figure-eight fully automatic CNC drilling machine is positioned on the building. S2: The automatic leveling device works, the whole machine is leveled, and the rollers are lifted into the air.

[0017] S2: Automatically starts the water drill rotation. The working gas supplied by the air source can enter the rodless chamber of the cylinder through the pneumatic-electric reversing valve. The cylinder extends and is pulled by the wire rope to advance the drill bit S2.

[0018] S3: After drilling is completed, the water drill stops rotating. The working gas supplied by the air source enters the rod chamber of the cylinder through the pneumatic-electric reversing valve. The cylinder retracts and pulls the drill bit back through the wire rope.

[0019] S4: Using the automatic lifting device, the upper frame is precisely and automatically raised to the second drilling point. Repeat steps S2 and S3 to complete the drilling of the second hole. Attached Figure Description
