[0020] like Figure 1-4 As shown, the deburring device for parts according to the present invention includes a worktable 1, a positioning mechanism disposed in the middle of the worktable 1, and a grinding mechanism disposed on both sides of the positioning mechanism.

[0021] The positioning mechanism includes a base plate 3. The lower part of the base plate 3 slides with the worktable 1 in the front-to-back direction via a guide rail 2. A guide groove 21 is machined in the middle of the guide rail 2 in the front-to-back direction. A first adjusting bolt 22 is installed in the guide groove 21 and locked to the base plate 3 for positioning. A drive seat 6 is mounted on the upper part of the base plate 3 via a U-shaped bracket 5. The left and right ends of the drive seat 6 are rotatably connected to the U-shaped bracket 5 via side positioning shafts 62 and locked for positioning via a third adjusting bolt 63. A pneumatic rotary chuck 61 is provided on the upper part of the drive seat 6 for clamping the workpiece 11. A support seat 4 is provided between the U-shaped bracket 5 and the base plate 3. The lower part of the support seat 4 is fixed to the base plate 3. A central positioning shaft 41 is provided at the center of the upper part of the support seat 4 and is rotatably connected to the U-shaped bracket 5. Second adjusting bolts 42 are symmetrically provided on both sides of the central positioning shaft 41. After the U-shaped bracket 5 rotates around the central positioning shaft 41, it is locked by the second adjusting bolts 42. The bottom of the U-shaped bracket 5 is machined with a waist-shaped groove I 52 to match the second adjusting bolts 42. The two sides of the U-shaped bracket 5 are machined with waist-shaped grooves 51 to match the third adjusting bolts 63.

[0022] The polishing mechanism includes a polishing wheel 10, which is mounted on the end of the shaft of the motor 9. The motor 9 is vertically adjusted by a second lead screw and slider mechanism 8. The lower part of the second lead screw and slider mechanism 8 is connected to the first slider 71 and forms a sliding fit with the worktable 1 in the front-back direction through the first lead screw and slider mechanism 77. The motor 9 is mounted on the front side of the second slider 81 of the second lead screw and slider mechanism 8. The horizontal position of the motor 9 is adjustable. The upper and lower sides of the motor 9 are machined with corresponding waist-shaped grooves II 91. A fourth adjusting bolt 92 is installed in the waist-shaped grooves II 91 and locked and positioned with the second slider 81. The two polishing wheels 10 rotate in the same direction.

[0023] The positions of the positioning mechanism and the grinding mechanism in this device can be adjusted in multiple directions, making it suitable for polishing and grinding workpieces of various shapes and sizes, and it has good versatility.

[0024] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;

[0025] During operation, the workpiece is clamped and positioned by a pneumatic rotary chuck. The angles of the U-shaped bracket and the drive seat are adjusted according to the surface of the workpiece to be processed. To adjust the position of the U-shaped bracket, simply loosen the second adjusting bolt, and the U-shaped bracket will rotate around the central positioning axis. The second adjusting bolt will slide along the waist-shaped groove I at the bottom of the U-shaped bracket. Once the specified angle is reached, the second adjusting bolt will be tightened. To adjust the position of the drive seat, simply loosen the third adjusting bolt, and the drive seat will rotate around the side positioning axis. The third adjusting bolt will slide along the waist-shaped groove on the side wall of the U-shaped bracket. Once the specified position is reached, the third adjusting bolt will be tightened. After the workpiece is positioned, the position of the polishing wheel is adjusted by the first and second lead screw and slider mechanisms, so that the surface of the polishing wheel contacts the surface of the workpiece to be polished. The motor drives the polishing wheel to rotate and polish the surface of the workpiece. At the same time, the drive seat drives the workpiece to rotate, so that the polishing wheel can completely polish the surface of the workpiece and remove surface burrs.
