Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically to a drilling machine and an eight-hole forming guide rail drilling device. Background Technology

[0002] Linear guides are high-precision mechanical components widely used in various mechanical equipment and automation systems. They enable linear motion and offer advantages such as high precision, high efficiency, and low friction. The selection of materials for linear guides is crucial, requiring materials with high strength, wear resistance, and corrosion resistance, such as carbon steel and special alloy steel. Furthermore, to improve the material's hardness and wear resistance, the cut material undergoes heat treatment, followed by machining processes including milling, grinding, and drilling.

[0003] In terms of drilling, the current process still involves drilling directly into the material with a drill bit. However, the hardness and toughness of the linear guide rails are enhanced after heat treatment. Ordinary drill bits often wear out quickly and need to be replaced frequently. High-quality drill bits are expensive and cannot solve the problem of drill bit wear. Summary of the Invention

[0010] The electrolyte enters the electrolysis channel through the inlet via the hollow spindle, and the excitation device supplies power to the tungsten wire electrode through the hollow spindle and generates an electric arc with the base material in the electrolyte.

[0011] Furthermore, the hollow spindle is equipped with a drainage component;

[0012] The drainage component includes:

[0013] The spiral blades are welded to both ends with mounting rings, which are fixedly installed inside the hollow main shaft.

[0014] A pair of conductors are welded and fixed on both sides of the mounting ring, with one end of each conductor inserted into the excitation device and the other end connected to a tungsten wire electrode.

[0015] Furthermore, the excitation device includes a cover, a permanent magnet, and a drain pipe. The drain pipe is connected to the liquid inlet, which is located at the tail of the cover. Permanent magnets are arranged circumferentially inside the cover and wrap around the outside of the drain pipe. A conductor is inserted into the drain pipe.

[0016] Furthermore, the power unit is an electric motor;

[0017] The power unit includes:

[0018] The motor housing contains a stator and has a sliding groove at the bottom;

[0019] The rotor winding is located outside the hollow main shaft and is coaxially connected to the hollow main shaft for transmission. The hollow main shaft is rotatably mounted at the center of the motor housing.

[0020] Furthermore, the special drilling tool includes a drill rod, a chuck, and contacts. The end of the drill rod is provided with a chuck, which is snapped and fixed inside the hollow spindle and abuts against the drainage component. A pair of contacts are provided on the chuck, and the contacts are connected to a conductor.

[0021] According to a second aspect of the invention,

[0022] This invention discloses an eight-hole forming guide rail drilling device for drilling holes in guide rails, comprising the aforementioned drilling machine, and including:

[0023] The bottom of the material guiding device is connected to the frame, and the frame is adapted to drive the material guiding device to move up and down. The top of the material guiding device is used to guide the guide rail.

[0024] A motor carrier is installed on the side of the material guiding device. The bottom of the motor carrier is connected to the support frame for transmission. Several drilling machines are slidably installed on the motor carrier along its length.

[0025] Furthermore, the motor carrier includes a guide plate, a guide slider, and a transmission slider. The transmission slider is disposed at the bottom of the guide slider, and a plurality of drilling rigs are disposed at the top of the guide slider.

[0026] Furthermore, the guide slider is provided with linear scales, and several of the drilling rigs are adapted to be fixed on the guide slider.

[0032] The present invention has the following advantages:

[0033] The drilling rig and eight-hole forming guide rail drilling equipment disclosed in this invention mainly adopt electroslag welding drilling technology. A power unit drives a hollow spindle to rotate, which in turn drives a current-guiding component to rotate. This causes the current-guiding component to cut the magnetic field of the excitation device, generating current, which is then transported to a tungsten wire electrode through a conductor. Furthermore, an electrolyte solution can be transported through the current-guiding component to generate an electric arc. The ablation effect of the electric arc removes metal from the workpiece surface, forming a hole. Compared to existing technologies that simply use a drill bit for drilling, this device, by primarily utilizing an electric arc to burn off the metal, significantly reduces wear on the drill rod. Combined with the use of an eight-hole forming guide rail drilling equipment, drilling efficiency is effectively improved. Attached Figure Description

[0048] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Please refer to this as well. Figures 1-6This invention discloses a drilling rig that uses electroslag welding to drill holes in metal workpieces. The principle involves forming an arc-shaped channel using electrodes, the workpiece, and an external medium (electrolyte). Typically, a tungsten electrode is used, and the external medium can be gasoline, water, or other similar substances. The workpiece is made of metal. An electric arc is formed between the tungsten electrode and the metal workpiece through a voltage difference. Under high temperature and pressure, the metal at the cathode of the drill bit is vaporized and compressed towards the anode, creating a significant temperature and pressure difference across the arc channel. As the arc travels across the workpiece surface, it melts and washes away the metal, forming a hole. The structure of this equipment will be described below with specific embodiments.

[0050] In one specific embodiment disclosed in this invention, such as Figure 1 and Figure 6 The drilling rig includes a power unit a1, an excitation device a3, and a special drilling tool a5. The power unit a1 is an electric motor or an internal combustion engine, and a hollow spindle a2 is installed inside it. The excitation device a3 is installed at the tail of the power unit a1. The excitation device a3 generates electricity and conducts the current outward along the hollow spindle a2. The head end of the hollow spindle a2 is connected to the special drilling tool a5. A pair of tungsten wire electrodes a4 are embedded on the outside of the special drilling tool a5. The current generated by the excitation device a3 flows into the tungsten wire electrodes a4 and forms an electric arc at the end of the tungsten wire electrodes a4, which is the end of the special drilling tool a5, to soften or burn metal materials. In this embodiment, the head of the excitation device a3 is connected to the hollow spindle a2, and the liquid inlet a6 is connected to the tail of the hollow spindle a2. The liquid inlet a6 is used for the inflow of electrolyte solution. In addition, the head of the hollow spindle a2 is also connected to the end of the special drill tool a5. The special drill tool a5 is provided with an electrolysis channel a8 inside. The electrolysis channel a8 is connected to the liquid inlet a6 through the hollow spindle a2. Thus, the electrolyte solution can flow into the end of the special drill tool a5 through the electrolysis channel a8. In conjunction with a pair of tungsten wire electrodes a4 embedded on the outside of the special drill tool a5, the generated electric arc burns and washes away the metal on the surface of the workpiece. The electrolyte solution can also play a cooling role to prevent the temperature of the special drill tool a5 from becoming too high.

[0051] In some embodiments, such as Figure 3 The hollow spindle a2 contains a flow guiding component a7, which includes a spiral blade a71 and a conductor a73. The spiral blade a71 has mounting rings 72 welded to both ends. The mounting rings 72 are conductors, fixed inside the hollow spindle a2, and rotate with the hollow spindle a2, thereby driving the spiral blade a71 to rotate. When the spiral blade a71 rotates, a negative pressure is formed inside the hollow spindle a2, which in turn drives the electrolyte solution to flow into the electrolysis channel a8 of the special drilling tool a5, thereby strengthening the electric arc and cooling the special drilling tool a5.

[0052] In some embodiments, such as Figure 4The excitation device a3 includes a housing a31, a permanent magnet a32, and a drain pipe a33. The drain pipe a33 is connected to an inlet a6, which is located at the tail of the housing a31. The permanent magnet a32 is circumferentially arranged inside the housing a31 and surrounds the drain pipe a33. A conductor a73 is inserted inside the drain pipe a33. Specifically, the conductor a73 is fixedly welded to both sides of the mounting ring 72, and the mounting ring 72 and a pair of conductors a73 form a circuit. The hollow main shaft a2 drives the conductor a73 to cut the magnetic field within the drain pipe a33 via the mounting ring 72. One end of the conductor a73 is inserted into the excitation device a3, and the other end is connected to the tungsten wire electrode a4. The current generated can be directly transmitted to the tungsten wire electrode a4 through the conductor a73 to generate an electric arc on the tungsten wire electrode a4.

[0053] In some embodiments, such as Figure 4 The power unit a1 is an electric motor, which includes a motor housing a11 and a rotor winding a12. The housing a11 contains a stator a13, and the bottom of the outer wall of the housing a11 has a sliding groove a14, which is slidably mounted on a guide plate. The rotor winding a12 is located outside the hollow main shaft a2 and is coaxially connected to the hollow main shaft a2 for transmission. The hollow main shaft a2 is rotatably mounted at the center of the motor housing a11.

[0054] In some embodiments, such as Figure 2 The special drilling tool a5 includes a drill rod a51, a chuck a52, and contacts a53. The chuck a52 is located at the end of the drill rod a51, and is fixed inside the hollow spindle a2, abutting against the current-guiding component a7. A pair of contacts a53 are provided on the chuck a52, and the contacts a53 are connected to a conductor a73. This allows current to flow through the conductor a73, through the contacts a53, into the tungsten wire electrode a4, thereby igniting an arc to burn away the metal material. In this embodiment, the drill rod a51 mainly serves to remove chips, and the arc generated at the end of the drill rod a51 by the tungsten wire electrode a4 can directly burn away the metal material. Compared to existing technologies, this method of physical metal cutting using ordinary drill bits significantly improves efficiency and greatly reduces wear on the drill rod a51.

[0055] Reference Figures 7-10Based on the same inventive concept, this invention also discloses an eight-hole forming guide rail drilling device for drilling holes in guide rails. The device includes the aforementioned drilling machine, a material guiding device b1, and a motor carrier b3. The material guiding device b1 is connected to a frame b4. A pair of motor carriers b3 are arranged on both sides of the frame b4. The bottom of the motor carrier b3 is connected to a support b2 for transmission. Several drilling machines are slidably arranged on the motor carrier b3 along its length. During use, the spacing between adjacent drilling machines can be adjusted to adjust the distance between the drilled holes. The frame b4 is adapted to drive the material guiding device b1 to move up and down. The top of the material guiding device b1 is used to guide the guide rails, and guide rails of different widths can be processed by adjusting the height of the material guiding device b1.

[0056] In some embodiments, such as Figure 10 The motor carrier b3 includes a guide plate b31, a guide slider b32, and a transmission slider b33. The transmission slider b33 is located at the bottom of the guide slider b32, and several drills are located at the top of the guide slider b32. The drills are slidably mounted on the guide plate b31 via a groove a14. The guide plate b31 is provided with a linear scale, and the drills are suitable for being fixed on the guide plate b31.

[0057] In some embodiments, such as Figure 9 The material guiding device b1 includes a frame b11, a support rod b13, and a guide roller assembly b14. The guide roller assembly b14 consists of several parallel rollers and is located in the middle of the frame b11. Straight grooves b12 are provided on both sides of the frame b11, and a material guiding groove b15 is provided on the top of the frame b1. When drilling holes for the guide rails, the guide rails are guided by the material guiding groove b15 and advance along the guide roller assembly b14, while the motor carrier b3 drills holes in the guide rails from both sides. Multiple guide rails can also be drilled simultaneously in the material guiding groove b15, thereby improving processing efficiency. Furthermore, one end of the support rod b13 is hinged to the frame b4, and the other end is slidably disposed within the straight groove b12 and is suitable for fixing within the straight groove b12, thereby achieving the purpose of adjusting the height of the frame b11.

[0058] In some embodiments, such as Figure 8 The support b2 includes side frames b21, rails b22, and an actuator b23. A pair of side frames b21 are arranged on both sides of the frame b4. The actuator b23 is located in the middle of the side frames b21, and is orthogonally arranged to the guide plate b31. A pair of rails b22 are arranged on both sides of the actuator b23, and guide sliders b32 are slidably mounted on the rails b22. In this embodiment, the actuator b23 is a hydraulic cylinder or a motor screw mechanism, and the actuator b23 pushes the guide slider b32 to move, thereby causing the drilling rig to feed and drill holes in the guide rail.

Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
