On the inner wall, it can meet the working needs of ring workpieces of different sizes and expand the scope of use. Then, the rotating motor 32 drives the rotating column 33 to rotate synchronously, so that the sliding block 34 slides in the chute. The sliding block 34 is different from the chute. When the position is in contact, the distance between the sliding block 34 and the side wall of the fixed plate 31 is different, so that the sliding block 34 performs a reciprocating linear motion in the limit frame 35, and under the auxiliary action of the telescopic rod 36 and the spring 37, the No. 1 wire brush 39 is driven. It performs reciprocating linear motion, so that the inner wall of the annular workpiece can be polished smoothly, and there is no need to manually use tools to polish the workpiece, which reduces labor costs and labor intensity, improves work efficiency, and eliminates the need to manually use tools to grind small-sized annular workpieces. The existence of obstacles ensures the grinding effect.

[0021]The fixing device 2 includes a linear guide 21, an electric slider 22, a sliding plate 23 and a fixing mechanism 24. The linear guide 21 is installed on the bottom plate 1, and the upper end of the linear guide 21 is installed with an electric slider 22 by sliding fit. A sliding plate 23 is installed on the upper end of 22, and a fixing mechanism 24 is installed on the sliding plate 23; after one end of the workpiece is fixed by the fixing mechanism 24, according to the actual size of the workpiece, the electric slider 22 drives the fixing mechanism 24 on the sliding plate 23 Moving on the linear guide 21, when moving to an appropriate position, the inner wall of the annular workpiece can be ground, the adjustment is flexible and convenient, the use range is wide, and the practicability is high.

[0022] The fixing mechanism 24 includes a mounting plate 241 , a driving motor 242 , a rotating panel 243 , an adjusting frame 244 , an adjusting electric push rod 245 , a telescopic adjusting plate 246 , a squeezing cylinder 247 and a squeezing plate 248 , and the mounting plate 241 is installed on the bottom plate 1 On the side wall of the mounting plate 241, a drive motor 242 is installed through the motor seat, the output shaft of the drive motor 242 is connected with the side wall of the rotating panel 243, the rotating panel 243 is closely attached to the side wall of the mounting plate 241, and the middle of the rotating panel 243 is installed with a Adjusting frame 244, the adjusting frame 244 is a U-shaped structure, and the left end of the adjusting frame 244 is a retractable structure in the left and right directions, the inner side wall of the adjusting frame 244 is connected with the top end of the adjusting electric push rod 245, and the adjusting electric push rod 245 is installed on the side of the rotating panel 243 On the wall, the rotating panel 243 is evenly installed with telescopic adjustment plates 246 along its circumferential direction. The number of the telescopic adjustment plates 246 is three. The pressing plate 248 and the pressing plate 248 are arc structures; after one end of the annular workpiece is closely attached to the side wall of the adjusting frame 244, the horizontal position of the pressing cylinder 247 is adjusted by the telescopic adjusting plate 246. The telescopic motion of the pressing cylinder 247 drives the pressing plate 248 to perform synchronous linear motion until the pressing plate 248 is close to the outer wall of the annular workpiece, thereby ensuring that the annular workpiece can also rotate synchronously when the driving motor 242 drives the rotating panel 243 to rotate. , Under the cooperation of the inner wall grinding device 3, every angle of the annular workpiece can be polished cleanly. When grinding the workpiece, the adjustment frame 244 can be adjusted by adjusting the electric push rod 245, thereby changing the workpiece and extrusion The relative position of the plate 248 enables every part of the workpiece to be ground without leaving dead corners, which improves the grinding effect.

[0023] When working, after the staff presses one end of the annular workpiece against the side wall of the adjustment frame 244, the horizontal position of the extrusion cylinder 247 is adjusted by the telescopic adjustment plate 246. The pressing plate 248 performs synchronous linear motion until the pressing plate 248 is in close contact with the outer wall of the annular workpiece, thereby limiting the position of the annular workpiece to ensure that when the driving motor 242 drives the rotating panel 243 to rotate, the annular workpiece can also rotate synchronously. At the same time, the electric sliding block 22 drives the fixing mechanism 24 on the sliding plate 23 to move on the linear guide rail 21 until the No. 1 wire brush 39 in the inner wall grinding device 3 extends into the annular workpiece, and then adjusts the telescopic motion of the cylinder 38 Adjust the position of the No. 1 wire brush 39 until the No. 1 wire brush 39 can be closely attached to the inner wall of the annular workpiece. Then, under the action of the driving motor 242, the annular workpiece rotates back and forth, and at the same time, the rotating motor 32 drives the rotating column 33. Synchronous rotation is performed, so that the sliding block 34 slides in the chute. When the sliding block 34 is in contact with different positions of the sliding groove, the distance between the sliding block 34 and the side wall of the fixed plate 31 is different, so that the sliding block 34 is in the limit frame 35. Carry out a reciprocating linear motion, under the auxiliary action of the telescopic rod 36 and the spring 37, the No. 1 wire brush 39 is driven to perform a reciprocating linear motion, so that the inner wall of the annular workpiece can be polished smoothly. When grinding the annular workpiece, adjust the electric push rod 245 adjusts the adjustment frame 244, so that the adjustment frame 244 drives the annular workpiece to perform linear motion, thereby changing the relative position of the workpiece and the extrusion plate 248, so that every part of the workpiece can be polished without leaving a dead angle, the present invention The problems of high labor cost, high labor intensity, low work efficiency, great difficulty in grinding and poor adjustability in the existing ring workpiece grinding process are solved, the function of automatic grinding of the ring workpiece is realized, and the purpose is achieved.
