[0002] After the workpiece is processed, the workpiece generally needs to be detected to find the surface quality problem and ensure the quality of the product. The existing workpiece surface detection is mostly manually detected by the workers through the handheld detection instrument to detect the defects of the workpiece surface one by one. However, the manual detection not only has a large labor intensity, but also has a low work efficiency, and the accuracy of the detection result is easily affected by the working state of the workers, especially when the column and the rotary workpiece are detected.

[0053] Please refer to Figures 1 to 3The detection mechanism comprises a screw rod 13 rotatably installed on the upper end of the inner cavity of the protective shell 1, the screw rod 13 is driven by the motor shaft of the second servo motor fixedly installed on the outer side of the protective shell 1, the screw rod 13 is sleeved with an inverted T-shaped plate 6, the screw rod 13 is threadedly connected with the inverted T-shaped plate 6, the upper end of the inverted T-shaped plate 6 is in left-right sliding contact with the upper end of the inner cavity of the protective shell 1, a concave bracket 61 is arranged below the inverted T-shaped plate 6, the upper end of the concave bracket 61 is fixedly connected with guide rods 62 in left-right symmetry, lower pressing springs 63 are sleeved on the two guide rods 62, the upper ends of the two guide rods 62 are upwardly penetrated through the lower end of the inverted T-shaped plate 6 and are fixedly sleeved with limiting rings 64, the guide rods 62 are in up-down sliding connection with the inverted T-shaped plate 6, the two ends of the lower pressing springs 63 are respectively in abutment with the inverted T-shaped plate 6 and the concave bracket 61, the lower pressing springs 63 apply downward elastic force to the concave bracket 61, the lower end of the concave bracket 61 is rotatably connected with rollers 65 through rotating shafts in left-right symmetry, a detection head 66 is fixedly installed on the inner side of the upper end of the concave bracket 61, cleaning brushes 67 are fixedly connected on the inner side of the upper end of the concave bracket 61 in left-right symmetry on the left and right sides of the detection head 66, the rollers 65 are in rolling contact with the upper end of the workpiece body 14, and the cleaning brushes 67 are in sliding contact with the workpiece body 14.

[0054] In the initial state, the rollers 65 are not in contact with the workpiece body 14, at this time, the concave bracket 61 is moved downward to the lowermost position under the elastic force of the lower pressing springs 63, and at this time, the lowermost end of the rollers 65 is below the uppermost end of the workpiece body 14.

[0055] The motor shaft of the second servo motor drives the screw rod 13 to rotate forward or reversely, the screw rod 13 drives the inverted T-shaped plate 6 to slide left and right, the concave bracket 61 is driven to move left and right by the guide rods 62 when the inverted T-shaped plate 6 moves left and right, when the concave bracket 61 moves to the upper side of the workpiece body 14, the rollers 65 first contact the workpiece body 14, when the rollers 65 roll to the upper end of the workpiece body 14, the workpiece body 14 pushes the rollers 65 to move upward, so that the lowermost end of the rollers 65 is in contact with the uppermost end of the workpiece body 14, the concave bracket 61, the cleaning brushes 67 and the detection head 66 are synchronously moved upward under the driving of the rollers 65, so that the detection head 66 is above the workpiece body 14, the cleaning brushes 67 are in contact with the upper end of the workpiece body 14, and the cleaning and detection of the workpiece are completed.

[0056] When the concave bracket 61 moves upward, the guide rods 62 slide upward along the inverted T-shaped plate 6, and the concave bracket 61 extrudes the lower pressing springs 63, the concave bracket 61 keeps the downward moving trend under the elastic force of the lower pressing springs 63, so that the rollers 65 and the cleaning brushes 67 can always be in contact with the workpiece body 14.

[0057] Working principle: when working, first, the workpiece body 14 to be detected is placed horizontally in the groove 31 of the two annular seats 3, the opening of which faces obliquely upward, so that the workpiece body 14 is placed in the V-shaped placement groove on the support block 46, and the workpiece body 14 is in contact with the rotating wheel 48 in the V-shaped placement groove, and the workpiece body 14 is supported by the support block 46 and the rotating wheel 48;

[0058] At this time, the output shaft of the stepping motor is rotated by one unit, the cylindrical column 27 is driven by the output shaft of the stepping motor, the rotating column 2 is driven by the cylindrical column 27 through the concave plate 26, the annular seat 3 is driven by the rotating column 2, the output shaft of the stepping motor stops rotating, and the workpiece body 14 to be detected is rotated to the uppermost position by the annular seat 3, so that the workpiece body 14 to be detected is just below the detection mechanism;

[0059] The piston rods of the two hydraulic oil cylinders 5 are extended to drive the two positioning supports 51 to move close to each other, the two positioning supports 51 drive the two clamping centers 53 to move close to each other, the workpiece body 14 is clamped and positioned by the two clamping centers 53, and the clamping center 53 is driven to rotate by the motor shaft of the first servo motor, and the workpiece body 14 is driven to rotate by the clamping center 53.

[0060] The screw rod 13 is driven to rotate by the motor shaft of the second servo motor, the inverted T-shaped plate 6 is driven to move by the screw rod 13, the concave bracket 61 is driven to move by the inverted T-shaped plate 6 through the guide rod 62, so that the concave bracket 61 moves close to the workpiece body 14;

[0061] When the concave bracket 61 moves to the upper side of the workpiece body 14, the roller 65 first contacts the workpiece body 14, when the roller 65 rolls to the upper end of the workpiece body 14, the workpiece body 14 pushes the roller 65 to move upward, so that the lowermost end of the roller 65 contacts the uppermost end of the workpiece body 14, and the roller 65 drives the concave bracket 61, the cleaning brush 67 and the detection head 66 to move upward synchronously, so that the roller 65, the concave bracket 61, the cleaning brush 67 and the detection head 66 move from one end of the workpiece body 14 to the other end;

[0062] When the cleaning brush 67 contacts the workpiece body 14, the cleaning brush 67 sweeps the sundries on the surface of the workpiece body 14, so as to prevent the sundries from affecting the subsequent detection result, and the detection head 66 moves away from above the workpiece body 14 to scan and detect the surface of the workpiece body 14;

[0063] After the workpiece body 14 is detected, the detection mechanism moves away from above the workpiece body 14, and another workpiece body 14 to be detected is placed horizontally in the groove 31 of the two annular seats 3, the opening of which faces obliquely upward, during the detection of the workpiece body 14, so as to complete the feeding operation.

[0064] At this time, the two clamping tips 53 are moved away from each other to loosen the clamping of the workpiece body 14, and the output shaft of the stepping motor is rotated to rotate the rotating column 2, the annular seat 3, the uppermost workpiece body 14 to be detected, and the next workpiece body 14 to be detected.

[0065] After detection, the output shaft of the stepping motor continues to rotate, at this time the annular seat 3 drives the workpiece body 14 just detected to rotate downward, and the annular seat 3 drives the previous workpiece body 14 to continue to rotate downward, at this time the opening of the groove 31 of the workpiece body 14 rotates to the obliquely downward direction, so that the workpiece body 14 slides outward along the groove 31, and the discharging operation is completed.

[0066] In this way, the feeding, detection and discharging operations can be continuously performed, and the feeding, detection and discharging operations can be performed synchronously, which greatly improves the work efficiency.

[0067] When it is necessary to detect workpiece bodies 14 with different diameters, the locking screw 82 is rotated outward along the threaded hole 25 until it is removed, at this time the locking screw 82 drives the light rod 83 to move into the threaded hole 25, the light rod 83 drives the limiting block 84 to move from one end of the rectangular groove 81 to the other end; at this time the locking screw 82 is pulled outward, the locking screw 82 drives the light rod 83 to move outward along the threaded hole 25, the light rod 83 slides along the contraction groove 24 through the limiting block 84, at this time the limiting block 84 drives the locking block 8 to move synchronously, the locking block 8 presses the locking spring 85, and at the same time the locking block 8 is separated from the limiting gear 71;

[0068] At this time, the handle 72 can be rotated as needed, the handle 72 drives the screw rod 4 to rotate through the round shaft 7, the screw rod 4 drives the regular polygon sliding sleeve 41 on it to slide along the regular polygon groove 21, the regular polygon sliding sleeve 41 drives the extrusion block 42 to slide along the sliding groove 22, the extrusion block 42 drives the T-shaped guide rail 43 to slide along the T-shaped groove 45, the transmission plate 44 is driven to slide along the lifting groove 33 through the T-shaped guide rail 43, the transmission plate 44 drives the support block 46 to slide along the groove 31, the support block 46 slides inwards or outwards along the groove 31, so as to adjust the position of the support block 46, so that the support block 46 and the rotating wheel 48 can always keep coaxial with the clamping tip 53, thereby realizing the support and positioning of the workpiece body 14 with different diameters by the support mechanism, and greatly improving the application range of the detection equipment.

[0069] When the adjustment is completed and the screw rod 4 needs to be fixed, i.e. the transmission mechanism is locked, the locking screw 82 is loosened, the locking block 8 is clamped with the limiting gear 71 under the elastic force of the locking spring 85, the locking screw 82 is screwed inward along the threaded hole 25, the light rod 83 is inserted into the locking block 8, and the light rod 83 drives the limiting circular block 84 to move along the rectangular groove 81 until the limiting circular block 84 abuts against one end of the rectangular groove 81. Through the cooperation of the locking spring 85, the locking screw 82, the light rod 83 and the limiting circular block 84, the locking block 8 is firmly clamped with the limiting gear 71, thereby locking the limiting gear 71. When the limiting gear 71 is locked, the circular shaft 7 and the screw rod 4 cannot rotate and are locked, thereby completing the locking of the transmission mechanism.
