Description

Technical Field

[0001] This utility model relates to the field of industrial production, and in particular to an angle-adjustable radial drill. Background Technology

[0002] A radial drilling machine is a drilling device widely used in metal processing and machinery manufacturing. It is mainly used for drilling, reaming, boring, tapping and other machining operations on workpieces. Its main structure includes a main frame, radial arm, spindle box, and worktable. The unique feature of a radial drilling machine is that its radial arm can move vertically. Combined with different worktable heights and workpiece sizes, it can achieve a wide range of machining operations. The spindle box is equipped with an electric motor, which drives the spindle to rotate through a transmission device to achieve contact between the drill bit and the workpiece.

[0003] The biggest advantage of radial drilling machines is their ability to handle large workpieces. Their structure allows for adjustment of the drill bit's working position, making them flexible and convenient to operate. Common radial drilling machines come in two forms: single-column and double-column. The single-column type is suitable for lighter workpieces, while the double-column type is more suitable for heavier and larger workpieces. Due to their adjustable working range, radial drilling machines can provide high-precision hole machining in different processing tasks.

[0004] Radial drills can be adjusted in multiple directions and angles. By moving the arm on the column, they can process holes with special angles. However, the movable parts between the column and the arm are relatively smooth, and long-term use will cause friction and wear, affecting the overall stability of the radial drill and causing deviations during drilling, resulting in insufficient workpiece processing accuracy. Therefore, an angle-adjustable radial drill is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an angle-adjustable radial drilling machine, which aims to improve the problem that long-term use of the device will cause wear and tear on the support column, affecting the overall stability of the radial drilling machine, causing deviations during drilling, and resulting in insufficient workpiece processing accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an angle-adjustable radial drill, including a worktable, a collection component installed on the right side of the worktable, a support column fixedly connected to the top of the worktable, a radial drill body installed on the outside of the support column, a motor fixedly connected to the top of the support column, a threaded rod fixedly connected to the output end of the motor, and a lubrication component installed on the top of the support column.

[0010] As a further description of the above technical solution:

[0011] The top of the threaded rod is rotatably connected to the upper side of the support column, and the external thread of the threaded rod is connected to the inside of the radial drilling body.

[0012] As a further description of the above technical solution:

[0013] The outer side of the cam abuts against the front end of the push rod, and the outer side of the piston is slidably connected to the inner wall of the housing.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the motor drives the threaded rod to rotate the cam, which pushes the push rod to move, causing the piston to compress the spring. In conjunction with the one-way valve, the lubricating oil is pumped into the body of the radial drilling arm, thus lubricating the friction points between the body of the radial drilling arm and the support column and avoiding wear and damage caused by long-term use.

[0024] 2. In this utility model, the second drive motor drives the magnetic shaft to rotate synchronously. While the water spray pipe is cooling down, the debris is flushed into the water tank. The liquid flows directly into the water tank, and the debris is attracted by the magnetic shaft and scraped off by the scraper to fall onto the collection box. This realizes that the debris can be automatically separated and collected during the cooling cycle, saving time and effort and avoiding clogging of the water spray pipe. Attached Figure Description

[0036] Working principle: When this device is used to drill holes in a workpiece, the water spray pipe 25 is controlled to spray water to cool the machining area of ​​the radial drilling body 3. Simultaneously, the water flow washes away the generated debris, which flows towards the water tank 16. At this time, the motor 17 is controlled to rotate. Under the action of the magnetic shaft 18, as the water flows into the water tank 16, the magnetic shaft 18 attracts the debris in the water, preventing it from falling into the water tank 16. Simultaneously, the rotation of the magnetic shaft 18, in conjunction with the spring 20, pushes the sliding plate 21, causing the scraper 22 to firmly press against the magnetic shaft 18, peeling the debris off the magnetic shaft 18 and allowing it to fall into the collection box 24 for collection and unified processing, preventing debris from clogging the water spray pipe 25. After the drill body 3 has been used for a period of time, wear will occur between the radial drill body 3 and the support column 2, requiring timely addition of lubricating oil. By opening valve 15, spring 8 will immediately push piston 9 to reset push rod 10 and make it contact cam 6, creating positive pressure on housing 7. Cam 6 then pushes push rod 10 backward, creating negative pressure on housing 7. With the cooperation of check valve 14, the piston 9 moves back and forth, squeezing out lubricating oil and adding it to the friction point between the radial drill body 3 and support column 2 along oil supply pipe 13, thus achieving lubrication. At this time, simply close valve 15, and push rod 10 will not reset, thus stopping the addition of lubricating oil. The operation is simple, time-saving, and labor-saving, effectively improving work efficiency.
