Detailed implementation manners

[0025] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific implementation manners of the present utility model will now be described with reference to the accompanying drawings.

[0026] As Figures 1-4 As commonly shown, the present utility model provides an end surface grinding device applicable to engine fan pulleys of different specifications, including a box body 1 fixedly connected above a base 2. A clamping mechanism 3 is installed at the bottom of the inner cavity of the box body 1, and the clamping mechanism 3 clamps and fixes the pulley 5. A grinding mechanism 4 is installed in the upper part of the inner cavity of the box body 1, and the grinding mechanism 4 grinds the front and back end surfaces of the pulley 5.

[0027] An outer door 11 made of a transparent material is installed in front of the box body 1, and the pulley 5 is taken and placed into the box body 1 from the outer door 11. A negative pressure suction port 12 is provided on the side of the box body 1, and the negative pressure suction port 12 is located outside the grinding position of the pulley 5. The negative pressure suction port 12 is connected to a negative pressure suction device through a pipeline to suck away and process the grinding dust.

[0028] The clamping mechanism 3 includes a chuck 31. The chuck 31 is installed on the base 2 through a fixed shaft 32. Four jaws 33 arranged in pairs are slidably connected to the chuck 31. The jaws 33 are respectively connected to a rotating seat 34 through a crank arm 35. One end of the crank arm 35 is hinged to the bottom of the jaw 33, and the other end of the crank arm 35 is hinged to the rotating seat 34.

[0029] The rotating seat 34 is sleeved on the fixed shaft 32 and can rotate by a certain angle along the fixed shaft 32.

[0030] Two first cylinders 36 arranged side by side are provided at the bottom of the chuck 31. The heads and tails of the first cylinders 36 are respectively connected to two oppositely arranged jaws 33. [[ID=ZZ]]

[0031] When the first cylinder 36 extends and retracts, it first drives the two jaws 33 connected to it to slide. The two jaws 33 drive the other two jaws 33 to slide under the cooperation of the crank arm 35 and the rotating seat 34. The four jaws 33 move simultaneously towards the center of the chuck 31, thereby clamping and fixing the pulley 5. By controlling the stroke of the first cylinder 36, not only can the front and back surfaces of the pulley 5 be clamped, but also the effective clamping of pulleys 5 of different specifications can be achieved.

[0032] The grinding mechanism 4 includes a liftable grinding disc 41. The center line of the grinding disc 41 is collinear with the center line of the chuck 3, and the diameter of the grinding disc 41 is larger than the outer diameter of the pulley 5. Therefore, the grinding disc 41 can grind the front and back end surfaces of the pulley 5.

[0033] The grinding disc 41 is installed on the output shaft of the motor 42, and the motor 42 drives it to rotate at a high speed.

[0034] The motor 42 is fixedly connected to the bottom of the lifting seat 43 through a bracket. The lifting seat 43 is connected to a second cylinder 44 arranged in the vertical direction. The second cylinder 44 is fixedly connected to the top of the box body 1. On the left and right sides of the second cylinder 44, there are guide rods 45 arranged parallel to it. The guide rods 45 are slidably arranged on the top of the box body 1. The bottom ends of the guide rods 45 are fixedly connected to the lifting seat 43. The guide rods 45 are used to ensure the stability of the grinding disc 41 during the lifting process.

[0035] The specific working principle of the present utility model:

[0036] The four jaws 33 in the present utility model are driven by the first cylinder 36. When the four jaws 33 move simultaneously towards the center of the chuck 31, the pulley 5 can be clamped and fixed. By controlling the stroke of the first cylinder 36, not only can the clamping of both the front and back sides of the pulley 5 be realized, but also the effective clamping of pulleys 5 of different specifications can be achieved.

[0037] The grinding disc 41 in the present utility model can not only rotate at a high speed driven by the motor 42, but also be lifted under the action of the second cylinder 44, so as to realize the grinding treatment of the end face of the pulley 5. By controlling the stroke of the second cylinder 44, the effective grinding of pulleys 5 of different specifications can be achieved.
