Description

Technical Field

[0001] This utility model relates to the field of drilling machine technology, specifically to a flushing mechanism for a pin drilling machine. Background Technology

[0002] A pin is a commonly used mechanical part, mainly used for connecting, positioning or preventing loosening of components. It is widely used in mechanical equipment, automobiles, aerospace, furniture and other fields. Generally, it is necessary to drill holes in the pin to optimize its structure. A pin drilling machine is usually used to drill holes in the pin.

[0003] In existing technology, the drilling process of pins using a pin drilling machine generally involves placing the parts of multiple pins to be drilled into a positioning mold, then pressing the pins against the mold, and finally drilling the pins by moving the drill bit vertically downwards at high speed. However, during the drilling process, the friction between the drill bit and the pin generates significant heat and debris, necessitating cooling the drill bit and cleaning the debris. This requires rinsing and cooling the drill bit and pins during the drilling process. Existing rinsing devices typically rinse the drill bit and pins during drilling, but this causes splashing of rinsing fluid. Furthermore, after drilling is completed and the drill bit is removed from the pins, manual cleaning with a high-pressure spray gun is required to remove debris from the positioning mold. This method increases the workload for workers and is inefficient. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rinsing mechanism for a pin drilling machine, comprising a working frame, a fixed frame slidably disposed within the working frame, a positioning mold fixedly connected within the fixed frame, the positioning mold having multiple drilling holes, and further comprising a fixing frame, a drilling mechanism, a rinsing mechanism, and a splash guard. The bottom end of the fixing frame is fixedly connected to the inner bottom wall of the working frame. The drilling mechanism is disposed on the fixing frame and is used to drill holes in the pins. The rinsing mechanism is disposed on the fixing frame and is used to rinse the positioning mold. One end of the splash guard is hinged to the top end of the fixing frame to prevent splashing of rinsing water.

[0008] Furthermore, the drilling mechanism includes an electric cylinder, a push plate, multiple mounting frames, a first motor, and a drill bit. The electric cylinder is mounted on the top of the fixed frame, and the output end of the electric cylinder passes through the top of the fixed frame. One end of the push plate is fixedly connected to the output end of the electric cylinder. One end of the multiple mounting frames is fixedly connected to the other end of the push plate. The first motor is mounted inside the mounting frame. One end of the drill bit is rotatably connected to the other end of the mounting frame and coaxially connected to the output end of the first motor.

[0009] Furthermore, the rinsing mechanism includes a water tank, a water pump, a water outlet pipe, a water distribution pipe, two rotary joints, two sets of fixed seats, a rinsing pipe, multiple high-pressure nozzles, and an adjusting component. The water tank is located at the top of the fixed frame. The water pump is installed on the outer wall of the water tank, and the input end of the water pump is connected to the water tank. One end of the water outlet pipe is connected to the output end of the water pump. The middle part of the water distribution pipe is connected to the other end of the water outlet pipe. One end of each of the two rotary joints is connected to both ends of the water distribution pipe. One end of each of the two sets of fixed seats is fixedly connected to the two side walls of the fixed frame. Each set of fixed seats includes two fixed seats.

The second motor is installed inside the waterproof frames, and the output end of the second motor is coaxially connected to the other end of the flushing pipe.

[0011] As a further step in this solution, multiple high-pressure nozzles are symmetrically arranged on both sides of the fixing frame and correspond to the drill holes.

[0012] Based on the aforementioned scheme, the splash guard is arc-shaped, and the other end of the splash guard contacts the two fixed seats.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a flushing mechanism for a pin drilling machine, which has the following beneficial effects:

[0015] In this invention, through the cooperation of the drilling mechanism and the positioning mold, the first motor drives the drill bit to rotate, and the electric cylinder drives multiple drill bits to move toward their corresponding drill holes. Multiple rotating and downward-moving drill bits enter the drill holes, thus drilling holes in multiple pins. Through the cooperation of the flushing mechanism and the splash guard, a water pump extracts water from the tank and transfers it to the high-pressure nozzles, thus flushing the drill holes and the area above them. A second motor drives the flushing pipe to rotate clockwise at a certain angle and then counterclockwise, driving multiple high-pressure nozzles to repeatedly swing, cooling the pins and drill bits, and removing debris from the drill holes. This operation is convenient and saves manpower, improving efficiency compared to manually cleaning debris with a handheld spray gun. Therefore, the flushing mechanism of this pin drilling machine solves the problem mentioned in the background art of the prior art where manual high-pressure spray guns are used to flush and remove debris from the positioning mold, increasing the workload of workers and resulting in low efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] Please see Figures 1 to 4 A flushing mechanism for a pin drilling machine includes a working frame 1, within which a fixed frame 2 is slidably mounted. Two first cylinders 22 are installed on the working frame 1, symmetrically arranged on one side of the fixed frame 2. Both ends of the fixed frame 2 are fixedly connected to a retaining seat 23. The output end of each first cylinder 22 is fixedly connected to one end of the retaining seat. The first cylinders 22 employ double-layer sealing and waterproof rubber rings to prevent liquid from seeping into their interior. Furthermore, the first cylinders 22 are made of water-resistant and corrosion-resistant materials such as stainless steel and engineering plastics, thus possessing a waterproof function. One end of the fixed frame... A positioning mold 3 is fixedly connected inside the fixed frame 2. The positioning mold 3 has multiple drill holes 4 and positioning holes 24 with the same number of drill holes 4 for placing pins. The fixed frame 2 is provided with a clamping component 25 for clamping the pin after one end of the pin enters the positioning hole 24. It also includes a fixed frame 5, a drilling mechanism, a flushing mechanism and a splash guard 6. The bottom end of the fixed frame 5 is fixedly connected to the inner bottom wall of the working frame 1. The fixed frame 5 is U-shaped. The fixed frame 2 and the two clamping seats 23 are all inside the fixed frame 5. The clamping seats 23 slide with the fixed frame 5.

[0024] like Figure 2 , Figure 3 and Figure 4As shown, a drilling mechanism is mounted on a fixed frame 5 for drilling holes in pins. The drilling mechanism includes an electric cylinder 7, a push plate 8, multiple mounting frames 9, a first motor 10, and a drill bit 11. The electric cylinder 7 is mounted on the top of the fixed frame 5, and its output end passes through the top of the fixed frame 5. One end of the push plate 8 is fixedly connected to the output end of the electric cylinder 7. One end of the multiple mounting frames 9 is fixedly connected to the other end of the push plate 8. The first motor 10 is mounted inside the mounting frames 9. One end of the drill bit 11 is rotatably connected to the other end of the mounting frames 9 and coaxially connected to the output end of the first motor 10. By starting the first motor 10... 0. The output of the first motor 10 rotates, driving the drill bit 11 to rotate. Then, the electric cylinder 7 is started. The output of the electric cylinder 7 pushes the push plate 8 to move downward. The push plate 8 drives multiple mounting frames 9, the first motor 10, and the drill bit 11 to move downward. The multiple drill bits 11 move toward the corresponding drill hole 4. After the pin is placed in the positioning hole 24, it is pressed by the clamping component 25. Then, multiple rotating and downward-moving drill bits 11 enter the drill hole 4 to drill a hole in the pin. After that, the electric cylinder 7 drives the multiple drill bits 11 to move out of the drill hole 4, thus completing the drilling work of the pin.

[0025] like Figure 1 , Figure 2 and Figure 4As shown, the rinsing mechanism is mounted on the fixed frame 5 and is used to rinse the positioning mold 3. The rinsing mechanism includes a water tank 12, a water pump 13, a water outlet pipe 14, a water distribution pipe 15, two rotary joints 16, two sets of fixed seats 17, a rinsing pipe 18, multiple high-pressure nozzles 19, and adjusting components. The water tank 12 is located at the top of the fixed frame 5. The water pump 13 is mounted on the outer wall of the water tank 12. The input end of the water pump 13 is connected to the water tank 12. One end of the water outlet pipe 14 is connected to the output end of the water pump 13. The middle part of the water distribution pipe 15 is connected to the other end of the water outlet pipe 14. One end of each of the two rotary joints 16 is connected to both ends of the water distribution pipe 15. The rotary joints 16 are commercially available... In conventional equipment, the rotary joint 16, through its internal rotatable sealing structure, allows fluid (such as steam, water, or hydraulic oil) to enter the flushing pipe 18 from the water distribution pipe 15. One end of each of the two sets of fixed seats is fixedly connected to the two side walls of the fixed frame 5. Each set of fixed seats 17 includes two fixed seats 17. The flushing pipe 18 passes through the fixed seats 17 and is rotatably connected to them. Both fixed seats 17 on the two outer side walls of the fixed frame 5 support the flushing pipe 18. One end of the flushing pipe 18 is connected to the other end of the rotary joint 16. One end of the high-pressure nozzle 19 is connected to the outer side wall of the flushing pipe 18. Multiple high-pressure nozzles 19 are symmetrically arranged on both sides of the fixed frame 5. Corresponding to drill hole 4, by starting water pump 13, water from water tank 12 is pumped out and moved to outlet pipe 14. Then, water is divided into two paths via water distribution pipe 15 and transferred to high-pressure nozzle 19 via rotary joint 16 and flushing pipe 18, thus flushing drill hole 4 and its surrounding area. An adjusting component is mounted on fixed base 17 for rotating flushing pipe 18. The adjusting component includes two waterproof frames 20 and a second motor 21. One end of each waterproof frame 20 is fixedly connected to one end of each fixed base 17 away from water tank 12. The second motor 21 is installed inside the waterproof frames 20. The output end of the flushing pipe 18 is coaxially connected to the other end of the flushing pipe 18. By starting the second motor 21, the output end of the second motor 21 rotates, driving the flushing pipe 18 to rotate. A rotary joint 16 is connected to one end of the flushing pipe 18. During the rotation of the flushing pipe 18, water can be continuously supplied inside the flushing pipe 18 and water leakage can be avoided. The rotation of the flushing pipe 18 drives multiple high-pressure nozzles 19 to rotate. After the second motor 21 rotates forward by a certain angle, it reverses. In this way, when drilling the pin, the pin and the drill bit 11 are repeatedly and continuously flushed, so that the pin and the drill bit 11 are cooled down. After the drill bit 11 is removed from the drill hole 4, the debris inside the drill hole 4 is removed by flushing the drill hole 4.

[0026] like Figure 1 and Figure 2As shown, one end of the splash guard 6 is hinged to the top of the mounting bracket 5 to block the splashing of the rinsing water. Both ends of the mounting bracket 5 are hinged with splash guards 6. The splash guard 6 is arc-shaped. The other end of the splash guard 6 contacts the two mounting seats 17. The splash guard 6 is made of waterproof rubber. By flipping the splash guard 6 on one side of the mounting bracket 5 upward, the pin can be placed in the positioning hole 24. Then, the splash guard 6 is flipped downward to cover both sides of the mounting bracket 5, preventing the rinsing water from splashing everywhere during the high-pressure nozzle 19 rinsing of the pin and drill bit 11.

[0027] It should be further explained that the second motor 21 in this embodiment is a conventional device known to those skilled in the art and available on the market. The model can be selected or customized according to actual needs. In this patent, we only use it without improving its structure and function. Its setting method, installation method and electrical connection method can be debugged and operated by those skilled in the art according to the requirements of its instruction manual, and will not be described in detail here. The second motor 21 is equipped with a matching control switch. The installation position of the control switch can be selected according to the actual use requirements to facilitate the operation and control of the operator. At the same time, the motor needs to be connected to the forward and reverse circuit before use for forward and reverse operation. As for the forward and reverse use of the motor, according to the patent disclosed by patent number CN109889124A, the forward and reverse operation of the motor is a well-known technology to those skilled in the art, and the technology is very mature and can be implemented.

[0028] Working principle: In use, the flushing mechanism of this pin drilling machine involves flipping the splash guard 6 upwards, placing the pin in the positioning hole 24, and then securing the pin with the clamping assembly 25. The splash guard 6 is then flipped downwards. The first motor 10 is started, and its output rotates, driving the drill bit 11 to rotate. Subsequently, the electric cylinder 7 is started, and its output pushes the push plate 8 downwards. The push plate 8 drives multiple mounting frames 9, the first motor 10, and the drill bit 11 downwards, moving the drill bit 11 towards its corresponding drill hole 4. Then, the water pump 13 is started, drawing water from the water tank 12 and moving it to the outlet pipe 14. The water is then divided into two paths by the water distribution pipe 15 and transferred to a high-pressure system via the rotary joint 16 and flushing pipe 18. At nozzle 19, the drill hole 4 and its area above are flushed. The second motor 21 is started, and the output of the second motor 21 rotates, driving the flushing pipe 18 to rotate. The rotation of the flushing pipe 18 drives multiple high-pressure nozzles 19 to rotate. After the second motor 21 rotates forward at a certain angle, it reverses, thus pre-activating the flushing mechanism before drilling the pin. Multiple rotating and downward-moving drill bits 11 enter the drill hole 4. During the drilling process on the pin, the pin and drill bits 11 can be repeatedly and continuously flushed to cool them down. After the drill bits 11 are removed from the drill hole 4, the debris inside the drill hole 4 is removed by flushing. Multiple rotating and downward-moving drill bits 11 enter the drill hole 4 to drill the pin. Then, the electric cylinder 7 drives multiple drill bits 11 to move out of the drill hole 4.
