Description

Technical Field

[0001] The present invention relates to the technical field of workpiece surface detection, and specifically provides a workpiece surface detection device. Background Art

[0002] After the workpiece is processed, it generally needs to be detected to find surface quality problems and ensure product quality. Currently, most workpiece surface detections are carried out manually. Workers use handheld detection instruments to detect the surface of each workpiece for defects one by one. However, manual detection not only has a high labor intensity but also low work efficiency. The accuracy of the detection results is easily affected by the working state of the workers, especially when detecting cylindrical or rotating workpiece, it is more inconvenient.

[0003] There are some existing workpiece surface detection devices, but there are still certain defects in the process of their use. The loading and unloading process of the existing workpiece surface detection device is relatively cumbersome. Especially for cylindrical workpieces, the position of the workpiece needs to be calibrated and positioned before each detection so that the clamping head can accurately clamp both ends of the workpiece, which increases the difficulty of workpiece positioning. This not only increases the burden on workers but also easily causes the position of the workpiece to be inaccurate and deviate, thus affecting the accuracy of detection. And after each workpiece detection is completed, it takes a lot of time to disassemble it and then load the next workpiece, greatly reducing the efficiency of workpiece detection and being very inconvenient.

[0015] The beneficial effects of the present invention are: 1.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 10, the present invention provides a technical solution: a workpiece surface detection device, including a protective housing 1. The bottom plate inside the protective housing 1 is fixedly connected with a concave-shaped support 11. Both the front and rear sides of the protective housing 1 are open. On both the left and right sides of the concave-shaped support 11, slide rods 12 are symmetrically fixedly connected in the front and rear directions. One end of the slide rod 12 away from the concave-shaped support 11 is fixedly connected with the inner side wall of the protective housing 1. On both the left and right sides of the concave-shaped support 11 above the slide rods 12, rotation driving mechanisms are symmetrically installed. Inside the concave-shaped support 11, a rotating column 2 is rotatably installed. Two annular seats 3 are fixedly sleeved on the rotating column 2. A plurality of grooves 31 are arranged in an annular array on the side surface of the annular seat 3. The grooves 31 on the two annular seats 3 are symmetrically distributed left and right. The grooves 31 on the two annular seats 3 correspond to each other one by one. A workpiece body 14 is installed in the two symmetrically distributed grooves 31 on the two annular seats 3. The workpiece body 14 straddles the symmetrically distributed grooves 31 on the two annular seats 3. A support mechanism is installed in each groove 31. A transmission mechanism is installed inside the rotating column 2. The transmission mechanism is used to adjust the position of the support mechanism. One end of the transmission mechanism is installed with a locking mechanism. At the upper end inside the protective housing 1 above the annular seat 3, a detection mechanism with a cleaning function is installed.

[0023] Please refer to Figure 1 and Figure 2 , the rotation driving mechanism includes a hydraulic cylinder 5 fixedly installed on the outside of the protective housing 1. The end of the piston rod of the hydraulic cylinder 5 passes through the side surface of the protective housing 1 and is fixedly connected with a positioning support 51. Symmetrically fixedly connected to the lower end of the positioning support 51 in the front and rear directions are sliding seats 52. On one side of the positioning support 51 close to the annular seat 3, a clamping center 53 is rotatably installed. The clamping center 53 is driven by the motor shaft of a first servo motor fixedly installed on the side surface of the positioning support 51. The first servo motor is installed on the side of the positioning support 51 away from the annular seat 3. The sliding seat 52 is sleeved on the slide rod 12, and the sliding seat 52 is slidably connected with the slide rod 12 in the left and right directions. The two clamping centers 53 in the two symmetrically distributed rotation driving mechanisms symmetrically abut against both ends of the workpiece body 14.

[0024] The two clamping centers 53 are against the central positions at both ends of the workpiece body 14. By extending the piston rods of the two hydraulic cylinders 5, the two positioning supports 51 are driven to move closer to each other. The positioning support 51 drives the sliding seat 52 to slide along the slide rod 12, so that the positioning support 51 can move stably. The two positioning supports 51 drive the two clamping centers 53 to move closer to each other. The workpiece body 14 is clamped and positioned by the two clamping centers 53. Then, the motor shaft of the first servo motor drives the clamping center 53 to rotate, and the clamping center 53 drives the workpiece body 14 to rotate, thus facilitating subsequent surface detection of the workpiece body 14.

[0025] Please refer to Figure 4 and Figure 5, both ends of the rotating column 2 are symmetrically and fixedly connected with concave plates 26 on the left and right. A cylinder 27 is fixedly connected to the side surface of the concave plate 26. The cylinder 27 is rotationally connected to the side surface of the concave support 11. One of the cylinders 27 is driven by the output shaft of a stepper motor fixedly installed on the outer side surface of the concave support 11, and the stepper motor is a stepper motor with a self-locking function.

[0026] The output shaft of the stepper motor drives the cylinder 27. The cylinder 27 drives the rotating column 2 to rotate through the concave plate 26, and the rotating column 2 drives the annular seat 3 to rotate. After the output shaft of the stepper motor rotates once, it stops for a period of time. Each time the output shaft of the stepper motor rotates once, it drives the annular seat 3 to rotate once. At this time, the groove 31 at the uppermost part of the annular seat 3 rotates downward, and at the same time, an adjacent groove 31 rotates to the uppermost part. That is, each time the output shaft of the stepper motor stops, a groove 31 on the annular seat 3 is exactly below the detection mechanism, and the opening of the groove 31 faces directly upward. This process repeats, so that the grooves 31 of the annular seat 3 are sequentially rotated below the detection mechanism.

[0027] When an opening of a groove 31 on the annular seat 3 faces directly upward, at this time, the openings of the two grooves 31 adjacent to the groove 31 with the opening facing directly upward face obliquely upward. At this time, the groove 31 with the opening facing obliquely forward and upward contains the detected workpiece body 14. When the annular seat 3 rotates again, at this time, the groove 31 containing the detected workpiece body 14 rotates downward so that its opening faces obliquely downward. At this time, the detected workpiece body 14 will roll out downward along the groove 31, thus completing automatic blanking. A shock-absorbing pad or a material receiving mechanism is installed on the side surface of the protective shell 1 to prevent damage to the workpiece body 14. At this time, the groove 31 with the opening facing obliquely backward and upward is empty. During the detection of the workpiece body 14 in the groove 31 with the opening facing directly upward, at this time, the groove 31 with the opening facing obliquely backward and upward is loaded. The workpiece body 14 to be detected is placed across the two grooves 31 with the openings facing obliquely backward and upward. When loading one workpiece body 14, one workpiece body 14 can be detected at the same time, and another workpiece body 14 can be unloaded at the same time, greatly improving the working efficiency.

The number of sliding grooves 22 provided at each end of the regular polygon groove 21 is more than 5, preferably 5. The transmission mechanism includes a screw rod 4 rotatably installed in the regular polygon groove 21. The screw rod 4 is rotatably connected to the rotating column 2 through a rotating shaft. Two regular polygon sliding sleeves 41 are sleeved on the screw rod 4. The screw rod 4 is threadedly connected to the regular polygon sliding sleeves 41. A plurality of extrusion blocks 42 are fixedly connected to the sides of the two regular polygon sliding sleeves 41 in an annular array. The number of extrusion blocks 42 is the same as the number of sliding grooves 22. The upper end of the extrusion block 42 is set as a slope surface. The extrusion block 42 is a triangular wedge block. An inclined T-shaped guide rail 43 is fixedly connected to the upper end of the extrusion block 42.

[0029] The regular polygon sliding sleeve 41 is slidably connected to the regular polygon groove 21 left and right. The extrusion block 42 and the T-shaped guide rail 43 are both arranged in the sliding groove 22, and the extrusion block 42 is slidably connected to the sliding groove 22 left and right.

[0030] By rotating the screw rod 4 forward or backward, the regular polygon sliding sleeve 41 thereon is driven to slide left and right along the regular polygon groove 21, and the regular polygon sliding sleeve 41 drives the extrusion block 42 to slide left and right along the sliding groove 22.

[0031] Please refer to Figure 4 , Figures 6 to 8 , guide grooves 32 are symmetrically provided on both inner side walls of the groove 31. A lifting groove 33 is penetrated and provided at the bottom of the groove 31. The position of the lifting groove 33 is aligned with the sliding groove 22. The lifting groove 33 communicates with the inner cavity of the annular seat 3, and the inner end of the lifting groove 33 communicates with the outer end of the sliding groove 22. The support mechanism includes a support block 46 slidably installed in the groove 31. The support block 46 slides from the inside to the outside along the groove 31. A V-shaped placement groove is provided on one side of the support block 46 away from the bottom of the groove 31. Rotating wheels 48 are symmetrically rotatably connected to both inclined inner side walls of the V-shaped placement groove. Rotating grooves are symmetrically provided on both inclined inner side walls of the V-shaped placement groove. The rotating wheels 48 are rotatably connected to the rotating grooves through rotating shafts. A transmission plate 44 is fixedly connected to one side of the support block 46 close to the bottom of the groove 31. The transmission plate 44 is penetrated and inserted in the lifting groove 33. One end of the transmission plate 44 away from the support block 46 extends into the sliding groove 22. An inclined surface is provided at one end of the transmission plate 44 extending into the sliding groove 22. The inclined surface of the transmission plate 44 is parallel to and in sliding contact with the slope surface of the extrusion block 42. A T-shaped groove 45 is provided at one end of the transmission plate 44 close to the extrusion block 42. The T-shaped groove 45 is slidably connected to the T-shaped guide rail 43. The T-shaped guide rail 43 is clamped in the T-shaped groove 45.

[0032] On both sides of the support block 46, guide blocks 47 are symmetrically and fixedly connected. The guide blocks 47 are slidably connected to the guide grooves 32, and the transmission plate 44 is slidably connected to the lifting groove 33.

[0033] When the extrusion block 42 moves left and right, it drives the T-shaped guide rail 43 to slide left and right along the T-shaped groove 45. By means of the T-shaped guide rail 43, the transmission plate 44 is pushed to slide along the lifting groove 33, so that the transmission plate 44 drives the support block 46 to slide along the groove 31, enabling the support block 46 to slide inwards or outwards along the groove 31. The support block 46 drives the guide block 47 to slide along the guide groove 32, enabling the support block 46 to slide stably, thereby realizing the adjustment of the position of the support block 46, enabling the support block 46 to support the workpiece body 14 with different diameters, and further enabling the workpiece body 14 to be coaxial with the clamping center 53.

[0034] When the workpiece body 14 is placed in the groove 31, the workpiece body 14 is located in the V-shaped placement groove on the support block 46. At the same time, the workpiece body 14 contacts the rotating wheel 48 in the V-shaped placement groove. The workpiece body 14 is supported by the cooperation of the support block 46 and the rotating wheel 48. When the workpiece body 14 rotates, the workpiece body 14 drives the rotating wheel 48 to roll synchronously, so that the workpiece body 14 can rotate stably.

[0035] Please refer to Figure 4 、 Figure 5 、 Figure 9 and Figure 10 As shown in FIGS.

[0036] The locking tooth block 8 is slidably connected to the contraction groove 24, the smooth rod 83 is slidably connected to the locking tooth block 8, the smooth rod 83 can slide along the threaded hole 25, and the limiting round block 84 abuts against one end of the rectangular groove 81, and the limiting round block 84 can slide along the rectangular groove 81.

[0037] When it is necessary to rotate the screw rod 4, first rotate the locking screw 82 outwards along the threaded hole 25. At this time, the locking screw 82 drives the smooth rod 83 to slide outwards along the locking tooth block 8, and the smooth rod 83 drives the limiting round block 84 to slide along the rectangular groove 81. When the locking screw 82 completely moves out of the threaded hole 25, the locking screw 82 drives the smooth rod 83 to move into the threaded hole 25, and the limiting round block 84 moves from one end of the rectangular groove 81 to the other end; At this time, pull the locking screw 82 outwards. The locking screw 82 drives the smooth rod 83 to move outwards along the threaded hole 25. The smooth rod 83 slides along the contraction groove 24 through the limiting round block 84. At this time, the limiting round block 84 drives the locking tooth block 8 to move synchronously. The locking tooth block 8 presses the locking spring 85, and at the same time, the locking tooth block 8 is separated from the limiting gear 71. At this time, the crank 72 can be rotated as needed, and the crank 72 drives the screw rod 4 to rotate through the round shaft 7.

[0038] When it is necessary to fix the screw rod 4, that is, when locking the transmission mechanism, loosen the locking screw 82. Under the action of the elastic force of the locking spring 85, the locking tooth block 8 is clamped with the limiting gear 71. Then screw the locking screw 82 into the threaded hole 25 inwards. The locking screw 82 drives the smooth rod 83 to insert into the locking tooth block 8. At the same time, the smooth rod 83 drives the limiting round block 84 to move along the rectangular groove 81 until the limiting round block 84 abuts against one end of the rectangular groove 81. Through the cooperation of the locking spring 85, the locking screw 82, the smooth rod 83, and the limiting round block 84, the locking tooth block 8 is firmly clamped with the limiting gear 71, so as to lock the limiting gear 71; When the limiting gear 71 is locked and cannot rotate, since the limiting gear 71 is fixedly connected to the round shaft 7, and the round shaft 7 is fixedly connected to the screw rod 4, the limiting gear 71, the round shaft 7, and the screw rod 4 rotate or stop synchronously. When the limiting gear 71 is locked, the round shaft 7 and the screw rod 4 also cannot rotate and are locked, thereby completing the locking of the transmission mechanism.

[0039] The limiting round block 84 is provided to abut against the locking tooth block 8 to prevent the locking tooth block 8 from separating from the limiting gear 71 during the rotation of the rotating column 2.

At this time, under the action of the elastic force of the compression spring 63, the concave-shaped bracket 61 moves downward to the lowest position. At this time, the lowest end of the rollers 65 is below the uppermost end of the workpiece body 14.

[0042] By driving the lead screw 13 to rotate forward or backward through the motor shaft of the second servo motor, the lead screw 13 drives the T-shaped plate 6 to slide left and right. When the T-shaped plate 6 moves left and right, it drives the concave-shaped bracket 61 to move left and right through the guide rods 62. When the concave-shaped bracket 61 moves above the workpiece body 14, the rollers 65 first come into contact with 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 upward, so that the lowest end of the rollers 65 is in contact with the uppermost end of the workpiece body 14. The rollers 65 drive the concave-shaped bracket 61, the cleaning brushes 67, and the detection head 66 to move upward synchronously, so that the detection head 66 is above the workpiece body 14, and the cleaning brushes 67 are in contact with the upper end of the workpiece body 14, completing the cleaning and detection of the workpiece.

[0043] When the concave-shaped bracket 61 moves upward, it drives the guide rods 62 to slide upward along the T-shaped plate 6. At the same time, the concave-shaped bracket 61 squeezes the compression spring 63. Under the action of the elastic force of the compression spring 63, the concave-shaped bracket 61 maintains a downward movement trend, so that the rollers 65 and the cleaning brushes 67 can always be in contact with the workpiece body 14.

[0044] Working principle: During operation, first place the workpiece body 14 to be detected across the grooves 31 with openings facing obliquely rearward and upward on the two annular seats 3, so that the workpiece body 14 is in the V-shaped placement groove on the support block 46. At the same time, the workpiece body 14 contacts the rotating wheel 48 in the V-shaped placement groove, and the workpiece body 14 is supported by the cooperation of the support block 46 and the rotating wheel 48; At this time, rotate the output shaft of the stepping motor by one unit. The output shaft of the stepping motor drives the cylinder 27. The cylinder 27 drives the rotating column 2 to rotate through the concave plate 26. The rotating column 2 drives the annular seat 3 to rotate. The output shaft of the stepping motor stops rotating. The annular seat 3 drives the workpiece body 14 to be detected to rotate to the uppermost position, so that the workpiece body 14 to be detected is exactly below the detection mechanism; The piston rods of the two hydraulic cylinders 5 extend to drive the two positioning supports 51 to move closer to each other. The two positioning supports 51 drive the two clamping tips 53 to move closer to each other. The workpiece body 14 is clamped and positioned by the two clamping tips 53. Then, the motor shaft of the first servo motor drives the clamping tip 53 to rotate, and the clamping tip 53 drives the workpiece body 14 to rotate.

[0045] The motor shaft of the second servo motor drives the lead screw 13 to rotate. The lead screw 13 drives the inverted T-shaped plate 6 to move. The inverted T-shaped plate 6 drives the concave bracket 61 to move through the guide rod 62, so that the concave bracket 61 moves closer to the workpiece body 14; When the concave bracket 61 moves above 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 upward, so that the lowermost end of the roller 65 contacts the uppermost end of the workpiece body 14. 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; After the cleaning brush 67 contacts the workpiece body 14, the cleaning brush 67 sweeps the debris on the surface of the workpiece body 14 to prevent the debris from affecting the subsequent detection results. After the detection head 66 moves past the workpiece body 14, the surface of the workpiece body 14 is scanned and detected; After the detection of the workpiece body 14 is completed, the detection mechanism is removed from above the workpiece body 14. During the detection process of this workpiece body 14, another workpiece body 14 to be detected is placed across the grooves 31 with openings facing obliquely rearward and upward on the two annular seats 3 at the same time, and the feeding operation is completed.

[0046] At this time, the two clamping tips 53 are moved away from each other to loosen the clamping of the workpiece body 14 by the clamping tips 53. Then, the output shaft of the stepping motor rotates to drive the rotating column 2 to drive the annular seat 3 to rotate. The annular seat 3 drives the workpiece body 14 that has been detected at the top to rotate downward, and at the same time, the annular seat 3 drives a workpiece body 14 to be detected to rotate to the uppermost end, and the above detection operation is repeated; After the detection is completed, the output shaft of the stepping motor continues to rotate. At this time, the annular seat 3 drives the workpiece body 14 that has just been detected to rotate downward, and at the same time, the annular seat 3 drives the workpiece body 14 that has been detected previously to continue to rotate downward. At this time, the opening of the groove 31 of the workpiece body 14 rotates to face obliquely downward, so that the workpiece body 14 slides outwards along the groove 31 to complete the blanking operation; In this way, the feeding, detection, and blanking operations can be continuously carried out, and the processes of feeding, detection, and blanking can be carried out synchronously, greatly improving the work efficiency.

[0047] When it is necessary to detect workpiece bodies 14 with different diameters, the locking screw 82 is rotated outwards along the threaded hole 25 until it is completely removed. At this time, the locking screw 82 drives the optical rod 83 to move into the threaded hole 25, and the optical rod 83 drives the limiting round 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 outwards, and the locking screw 82 drives the optical rod 83 to move outwards along the threaded hole 25. The optical rod 83 slides along the contraction groove 24 through the limiting round block 84. At this time, the limiting round block 84 drives the locking tooth block 8 to move synchronously. The locking tooth block 8 presses the locking spring 85, and at the same time, the locking tooth block 8 is separated from the limiting gear 71; At this time, the crank 72 can be rotated as needed. The crank 72 drives the screw rod 4 to rotate through the round shaft 7. The screw rod 4 drives the regular polygon sliding sleeve 41 thereon 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 pushed along the lifting groove 33 through the T-shaped guide rail 43, so that the transmission plate 44 drives the support block 46 to slide along the groove 31, and 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 drive the workpiece body 14 to always be coaxial with the clamping tip 53, so as to realize the support and positioning of the support mechanism for workpiece bodies 14 with different diameters, greatly improving the applicable range of the detection equipment.

[0048] After the adjustment is completed, it is necessary to fix the screw rod 4, that is, when locking the transmission mechanism, loosen the locking screw 82. Under the action of the elastic force of the locking spring 85, the locking tooth block 8 is engaged with the limit gear 71. Then, screw the locking screw 82 into the threaded hole 25 inward. The locking screw 82 drives the optical rod 83 to insert into the locking tooth block 8. At the same time, the optical rod 83 drives the limit round block 84 to move along the rectangular groove 81 until the limit round block 84 abuts against one end of the rectangular groove 81. Through the cooperation of the locking spring 85, the locking screw 82, the optical rod 83, and the limit round block 84, the locking tooth block 8 is firmly engaged with the limit gear 71, thereby locking the limit gear 71. When the limit gear 71 is locked, the round shaft 7 and the screw rod 4 also cannot rotate and are locked, thus completing the locking of the transmission mechanism.
