Description

Technical Field

[0001] The present invention relates to the technical field of new energy transmission housing production, and particularly to a deburring device for cross oil holes of a new energy transmission housing. Background Art

[0002] At present, the structure of new energy transmissions is complex, and there are channels for lubricating oil to flow on the transmissions, namely oil holes, and these oil holes often cross each other. When processing cross oil holes, burrs at the intersection are often inevitable. When the transmission is working, the high-pressure and fast-flowing lubricating oil in the oil holes will impact the burrs at the intersection, causing the burrs to fall off and enter the lubrication system of the transmission along with the lubricating oil. The fallen burrs are extremely harmful in the lubrication system and may cause the entire transmission to be scrapped. At present, the methods for removing burrs from cross oil holes have many limitations and poor effects, and how to efficiently remove burrs from cross oil holes has become a difficult problem in the industry. Summary of the Invention

This deburring device can efficiently remove burrs at the cross oil holes of the transmission housing.

[0004] The purpose of the present invention is achieved by the following solution: A deburring device for cross oil holes of a new energy transmission housing includes a guide rod. A blade mounting groove is provided at the front end of the guide rod, and a handle is provided at the rear end of the guide rod. A spring is inclinedly arranged at the lower part of the rear end of the blade mounting groove, and a blade is inclinedly arranged at the lower part of the front end of the blade mounting groove. The upper end of the spring is connected and fixed to the blade through a spring connection hole provided in the middle of the blade. A guide sleeve is provided on the outer circumference of the front end of the guide rod. An opening groove for the blade to give way is provided at the corresponding position of the front end sleeve wall of the guide sleeve and the blade mounting groove. The top of the blade extends out of the opening groove. The guide sleeve is sleeved on the front end of the guide rod to form the deburring device.

[0005] The lower end of the spring is connected and fixed to the lower part of the rear end of the blade mounting groove through a spring connection pin.

[0006] The lower end of the blade is connected and fixed to the lower part of the front end of the blade mounting groove through a blade connection pin.

[0007] A limit screw for adjusting the inclination angle of the blade is provided at the center of the front end face of the guide rod.

[0008] The opening groove on the guide sleeve is a strip-shaped opening groove.

[0009] The blade includes a pin connection hole provided at the rear end of the blade, a spring connection hole provided in the middle section of the blade, a cutting edge provided at the front end of the pin connection hole. The side surface of the cutting edge is the front cutting surface facing the blade mounting groove, the bottom surface of the cutting edge is the rear cutting surface, and the intersection of the front cutting surface and the rear cutting surface is the cutting edge.

Detailed Embodiments

[0015] Such as Figures 1 to 3As shown in the figure, the object of the present invention is achieved by the following solution: A deburring device for cross oil holes of a new energy transmission housing, including a guide rod 1. A blade mounting groove 1a is provided at the front end of the guide rod 1, and a handle 1b is provided at the rear end of the guide rod 1. The circumference of the handle 1b is provided with grid lines for increasing friction. A spring 5 is inclined and arranged at the lower part of the rear end of the blade mounting groove 1a. The lower end of the spring 5 is fixedly connected to the lower part of the rear end of the blade mounting groove 1a through a spring connection pin 6. A blade 2 is inclined and arranged at the lower part of the front end of the blade mounting groove 1a. The lower end of the blade 5 is fixedly connected to the lower part of the front end of the blade mounting groove 1a through a blade connection pin 4. The upper end of the spring 5 is fixedly connected to the blade 2 through a spring connection hole 2d provided in the middle of the blade 2. The blade 2 includes a pin connection hole 2e provided at the rear end of the blade 2, a spring connection hole 2d is provided in the middle section of the blade 2, a cutting edge is provided at the front end of the pin connection hole 2e. The side surface of the cutting edge is a front cutting surface 2c facing the blade mounting groove 1a, the bottom surface of the cutting edge is a rear cutting surface 2a, and the intersection of the front cutting surface 2c and the rear cutting surface 2a is a cutting edge 2b. A guide sleeve 7 is arranged on the outer circumference of the front end of the guide rod 1. An opening groove 7a for the blade 2 to give way is provided at the corresponding position of the front end sleeve wall of the guide sleeve 7. The top of the blade 2 extends out of the opening groove 7a. The opening groove 7a on the guide sleeve 7 is a strip-shaped opening groove. The guide sleeve 7 is sleeved on the front end of the guide rod 1 to form a deburring device. A limit screw 3 for adjusting the inclination angle of the blade 2 is provided at the center of the front end face of the guide rod 1. By adjusting the limit screw, the inclination angle of the blade 2 is restricted to achieve the purpose of controlling the size of the deburring chamfer.

[0016] Push the guide rod into the guide sleeve, the top of the blade contacts the inner wall of the guide sleeve, and then the spring is in a compressed state. Then insert the whole into the oil hole until the end face of the guide sleeve fits the end face of the product, as Figure 4 shown in Stage 1.

[0017] Press the guide sleeve by hand, and then pull the guide rod backward to drive the blade to move backward. When the blade passes through the opening groove on the guide sleeve, the spring becomes in a free state, and then drives the blade to rotate, so that the blade pops out through the opening groove, as Figure 4 shown in Stage 2.

[0018] Pull the guide rod, make the cutting edge of the blade contact the outer contour of the cross oil hole, continue to pull the guide rod until the back of the blade touches the limit screw. Release the hand pressing the guide sleeve, and rotate the guide rod counterclockwise. At this time, the blade drives the guide sleeve to rotate together in the opening groove. Cut the burrs on the outer contour of the cross oil hole through the cutting edge to achieve the purpose of removing burrs. As Figure 4 shown in Stage 3.

[0019] After deburring is completed, push the guide rod forward. The back of the blade contacts the edge of the opening groove, thereby compressing the spring and retracting the blade into the guide sleeve. Then, remove the tooling as a whole to complete one working cycle.

[0020] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications made by those skilled in the art without departing from the spirit of the present invention fall within the protection scope of the present invention.
