[0013] Compared with the prior art, the present invention provides an engine connecting rod hole chamfering and burr cleaning device, which has the following beneficial effects:
[0014] 1. The utility model pushes the telescopic rod outward by pushing the threaded rod, so that the chamfer cutter is fitted with the inner wall of the connecting hole, and the power gear is meshed with the external motor gear to drive the rotating rod to rotate so that the chamfer cutter chamfers the inside of the connecting hole. During the cutting process, the high-pressure nozzle installed at the connection of the fixed rod will spray high-pressure water to perform high-pressure flushing on the cutting position of the chamfer cutter, so that the chamfer cutter can clean the chamfer burrs at the same time as cutting, without the need to replace the chamfer cutter, thereby improving the overall work efficiency of chamfer burr cleaning.
[0015] 2. In the present invention, when the rotating rod rotates, the water stored inside the rotating rod will enter the interior of the booster valve under the action of centrifugal force. The booster valve pressurizes the water flow inside it, and enters the interior of the high-pressure nozzle through the water pipe.

[0016] 3. The utility model can be connected to the power gear by rotating the connecting rod installed at the upper end of the rotating rod. When the power gear rotates, it will drive the connecting rod to rotate. In order to prevent uncontrollable power transmission, the connecting rod will drive the rotating rod to rotate one circle when the power gear rotates two weeks, so as to avoid the situation where the chamfer cutter damages the inner wall of the connecting hole when the power gear rotates too fast and an uncontrollable situation occurs. Through the water storage valve, when it is necessary to supply water to the inside of the rotating rod, the water storage valve can be opened to connect the water storage pipe with the external water source, and water can be transported to the inside of the rotating rod through the water storage pipe. After the internal water flow of the rotating rod is completed, the water storage valve is closed to prevent water from leaking out, thereby achieving the effect of water supply.
[0017] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. The utility model has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0025] Embodiment 1: An engine connecting rod hole chamfering and burr cleaning device, such as Figures 1-4As shown, it includes an assembly plate 1 and a rotating rod 7 arranged inside the assembly plate 1. Several fixing rods 9 are fixedly installed on the surface of the rotating rod 7. A telescopic rod 10 is slidably installed inside the fixing rod 9. The internal thread of the fixing rod 9 is screwed with a pushing threaded rod 17. One end of the telescopic rod 10 is fixedly installed with a chamfering cutter 18. Several high-pressure nozzles 13 are installed on the surface of the rotating rod 7. When it is necessary to chamfer the connecting rod hole, after placing the rotating rod 7 inside the assembly plate 1, the telescopic rod 10 can be pushed outward by the pushing threaded rod 17 installed by the internal thread of the fixing rod 9, thereby fixing one end of the telescopic rod 10. The chamfer cutter 18 is fitted with the inner wall of the connecting hole 3, and is meshed with the external motor gear through the power gear 8 installed above the rotating rod 7, driving the rotating rod 7 to rotate so that the chamfer cutter 18 installed on the outside can chamfer the inside of the connecting hole 3. During the cutting process of the chamfer cutter 18, the high-pressure nozzle 13 installed at the connection of the fixed rod 9 will spray out a high-pressure water flow to perform high-pressure washing on the part cut by the chamfer cutter 18, and then complete the cleaning of the chamfer burrs while the chamfer cutter 18 is cutting, so that there is no need to replace the chamfer cutter, thereby improving the overall work efficiency of cleaning the chamfer burrs.
[0026] like Figures 1-4 As shown, several boosting valves 11 are fixedly installed on the surface of the rotating rod 7, and a water pipe 12 is fixedly installed on the upper end of the boosting valve 11. A high-pressure nozzle 13 is fixedly installed on the end of the water pipe 12 away from the boosting valve 11. When the rotating rod 7 rotates, the water stored inside the rotating rod 7 will enter the inside of the boosting valve 11 under the action of centrifugal force. The boosting valve 11 pressurizes the water flow inside it, and enters the inside of the high-pressure nozzle 13 through the water pipe 12. The high-pressure nozzle 13 evenly sprays the pressurized water flow on the cutting area of the chamfering cutter 18, thereby achieving the effect of high-pressure cleaning of burrs at the cutting area.
[0027] like Figures 1-4As shown, a connecting rod 14 is rotatably mounted on one end of the rotating rod 7, a power gear 8 is fixedly mounted on the end of the connecting rod 14 away from the rotating rod 7, a water storage valve 15 is fixedly mounted on the end of the rotating rod 7 away from the power gear 8, and a water storage pipe 16 is fixedly mounted on the end of the water storage valve 15 away from the rotating rod 7. The connecting rod 14 rotatably mounted on the upper end of the rotating rod 7 can be connected to the power gear 8. When the power gear 8 rotates, the connecting rod 14 will be driven to rotate. In order to prevent uncontrollable power transmission, the connecting rod 14 is rotated when the power gear 8 rotates two weeks. It will drive the rotating rod 7 to rotate one circle, avoiding the situation where the chamfering cutter 18 causes damage to the inner wall of the connecting hole 3 when the power gear 8 rotates at too fast a speed, resulting in an uncontrollable situation. Through the provided water storage valve 15, when it is necessary to supply water to the inside of the rotating rod 7, the water storage valve 15 can be opened to connect the water storage pipe 16 with the external water source, and water flow can be transported to the inside of the rotating rod 7 through the water storage pipe 16. After the internal water flow transportation of the rotating rod 7 is completed, the water storage valve 15 is closed to prevent water from leaking out, thereby achieving the effect of water supply.
[0028] Embodiment 2: An engine connecting rod hole chamfering and burr cleaning device, such as Figures 1-4 As shown, connecting holes 3 are provided on both side surfaces of the assembly plate 1, and two fixing components 2 are fixedly installed on the surfaces of the connecting holes 3.

Through the provided connecting holes 3, it can be connected to the engine when the engine power is transmitted, and the provided fixing components 2 can fix the connecting holes 3. Through the provided combination rod 4, a combined installation effect can be achieved. The assembly parts 6 can be fixedly installed on both side surfaces thereof, and the provided assembly parts 6 can be connected and fixed to automobile engine accessories to achieve a connection and assembly effect.
[0029] like Figures 1-4 As shown, a mounting assembly 5 is fixedly mounted on the surface of the combination rod 4 on one side away from the assembly plate 1 . The mounting assembly 5 can be used to mount the engine connecting rod and automobile parts, thereby playing a mounting role.
[0030] Working principle: When the connecting rod hole needs to be chamfered, the rotating rod 7 is placed inside the assembly plate 1, and the telescopic rod 10 can be pushed outward by the pushing threaded rod 17 installed by screwing the threaded rod inside the fixed rod 9, so that the chamfering cutter 18 fixed at one end of the telescopic rod 10 is fitted with the inner wall of the connecting hole 3. The power gear 8 installed above the rotating rod 7 is engaged with the external motor gear to drive the rotating rod 7 to rotate so that the chamfering cutter 18 installed on the outside can chamfer the inside of the connecting hole 3. During the cutting process of the chamfering cutter 18, the high-pressure nozzle 13 installed at the connection of the fixed rod 9 will spray outward. The high-pressure water flow is sprayed to perform high-pressure washing on the part cut by the chamfer cutter 18, and the chamfer burrs are cleaned while the chamfer cutter 18 is cutting, so that there is no need to replace the chamfer cutter, and the overall work efficiency of cleaning the chamfer burrs is improved. When the rotating rod 7 rotates, the water stored in the rotating rod 7 enters the inside of the boosting valve 11 under the action of centrifugal force. The boosting valve 11 pressurizes the water flow inside it, and enters the inside of the high-pressure nozzle 13 through the water pipe 12. The pressurized water flow is evenly sprayed on the cutting part of the chamfer cutter 18 through the high-pressure nozzle 13, thereby achieving the purpose of cleaning the chamfer burrs. The effect of high-pressure cleaning burrs at the cutting position is achieved by rotating the connecting rod 14 installed at the upper end of the rotating rod 7 to connect with the power gear 8. When the power gear 8 rotates, the connecting rod 14 will be driven to rotate. In order to prevent the power transmission from being uncontrollable, the connecting rod 14 will drive the rotating rod 7 to rotate for one circle when the power gear 8 rotates two weeks, so as to avoid the power gear 8 rotating at too fast a speed, and the chamfering cutter 18 will cause damage to the inner wall of the connecting hole 3 and cause uncontrollable damage. Through the water storage valve 15, when it is necessary to supply water to the inside of the rotating rod 7, the water storage pipe can be opened by opening the water storage valve 15. 16 is connected to an external water source, and water is transported to the inside of the rotating rod 7 through the water storage pipe 16. After the internal water flow transportation of the rotating rod 7 is completed, the water storage valve 15 is closed to prevent water from leaking out, thereby achieving the effect of water supply. Through the provided connecting hole 3, it can be connected to the engine when the engine power is transmitted. The provided fixing component 2 can fix the connecting hole 3. Through the provided combination rod 4, it can achieve the effect of combined installation. The assembly parts 6 can be fixedly installed on its two side surfaces.
