Detailed implementation manners

[0025] Please refer to Figure 1-8 , the present invention provides a technical solution: a laser rust removal equipment for bolts, including a workbench 1, and a laser generating device 2 is arranged on the top of the workbench 1; a support plate 3 is fixedly installed on the top of the workbench 1, a first slide plate 4 and a second slide plate 5 are slidably installed on the support plate 3, a first positioning cylinder 6 is rotatably connected to the first slide plate 4, a plurality of first clamping blocks 7 distributed in a circumferential array are arranged in the first positioning cylinder 6, and the first clamping blocks 7 are elastically slidably connected to the first positioning cylinder 6; a first driving mechanism for driving the first slide plate 4 to move linearly is arranged on the side of the first slide plate 4; a second positioning cylinder 8 is rotatably connected to the second slide plate 5, a clamping rod 9 is arranged in the second positioning cylinder 8, and one end of the clamping rod 9 extends outside the second positioning cylinder 8; a first slider 10 is fixedly connected to the clamping rod 9, the first slider 10 is slidably connected to the second positioning cylinder 8, and a pressure spring 11 for resetting the first slider 10 is arranged in the second positioning cylinder 8; a plurality of second clamping blocks 12 distributed in a circumferential array are arranged in the second positioning cylinder 8, and the second clamping blocks 12 are elastically slidably connected to the second positioning cylinder 8; a limiting mechanism for limiting the first slider 10 is further arranged in the second positioning cylinder 8; a second driving mechanism for driving the second slide plate 5 to move linearly is arranged on the side of the second slide plate 5.

[0026] The limiting mechanism includes a first limiting block 13 and a second limiting block 14, both the first limiting block 13 and the second limiting block 14 are elastically slidably connected to the second positioning cylinder 8 in the vertical direction, an arc-shaped push block 15 is arranged on the side of the first limiting block 13, and inclined surfaces are arranged at both ends of the arc-shaped push block 15; the arc-shaped push block 15 is fixedly installed on the top of the workbench 1, and an inclined surface is arranged at one end of the first limiting block 13 close to the arc-shaped push block 15; a trapezoidal push block 16 is arranged on the side of the second limiting block 14, and the trapezoidal push block 16 is rotatably installed on the top of the workbench 1.

[0027] During operation, the staff places fasteners such as bolts to be processed between the first positioning cylinder 6 and the second positioning cylinder 8, and then starts the first driving mechanism. The first driving mechanism will drive the first sliding plate 4 to move towards the second sliding plate 5. The first sliding plate 4 will drive the first positioning cylinder 6 and the first clamping block 7 to move synchronously. The inner diameter of the first positioning cylinder 6 is larger than the outer diameter of the right end of the bolt, and the bolt can be directly sleeved into the first positioning cylinder 6. As Figure 6 shown, the left end of the first clamping block 7 is provided with an inclined surface. The inner diameter of the ring formed by a plurality of first clamping blocks 7 is smaller than the outer diameter of the bolt. Therefore, when the bolt is sleeved into the first positioning cylinder 6 and the first positioning cylinder 6 continues to move to the left, the bolt will make the first clamping block 7 move outward by pressing the inclined surface of the first clamping block 7. When the bolt is stuck inside a plurality of first clamping blocks 7, the plurality of first clamping blocks 7 will cooperate with the spring to clamp the right end of the bolt, and it can ensure that the axis of the bolt coincides with the axis of the first positioning cylinder 6. When the right end face of the bolt fits against the right inner wall of the first positioning cylinder 6 and the left end contacts the clamping rod 9, the first driving mechanism stops working. At this time, the clamping rod 9 cooperates with the first clamping block 7 to fix the bolt. It should be noted that as Figure 4 shown, in the initial state, the first slider 10 is limited by the first limiting block 13, and the position of the clamping rod 9 is fixed. When the left end of the bolt contacts the clamping rod 9, the left end of the bolt is exactly located directly below the laser generating device 2. Then, the laser generating device 2 starts to work. When the laser irradiates on the surface of the bolt, it can remove the rust layer on the surface of the bolt. While the laser generating device 2 is working, an external motor drives the first positioning cylinder 6 and the second positioning cylinder 8 to rotate synchronously and uniformly. The first positioning cylinder 6 will drive the bolt to rotate synchronously through the first clamping block 7. Since the position of the laser generating device 2 is fixed and the position of the bolt is fixed by a plurality of first clamping blocks 7 together, the distance between the bolt and the laser generating device 2 remains the same during the rotation process of the bolt, which can make the rust layer on the surface of the bolt be better removed by the laser. It should be noted that as Figure 5As shown, the second positioning cylinder 8 will drive the first limit block 13 to rotate synchronously when it rotates. When the first limit block 13 rotates to be offset from the arc-shaped push block 15, the first limit block 13 will move downward a short distance (after moving, it can also limit the first slider 10). At this time, the bottom end of the first limit block 13 is located on the side of the inclined surface of the arc-shaped push block 15; when the first limit block 13 rotates one circle, the inclined surface on the arc-shaped push block 15 will drive the first limit block 13 to move downward, so that the first limit block 13 cancels the limit on the first slider 10; at this time, the rust layer on the left end of the bolt is removed by the laser , then the laser generating device 2 stops working, and the first driving mechanism drives the first slide plate 4 to move to the left; at this time, the first slide plate 4 will drive the bolt to move to the left synchronously through the first positioning cylinder 6 and the first clamping block 7, and the bolt will move to the left against the clamping rod 9, and the clamping rod 9 will drive the first slider 10 to move to the left synchronously and compress the pressure spring 11; until the first slider 10 moves to the left side of the second limit block 14, at this time the second limit block 14 will limit the first slider 10; the part where the bolt surface treatment is completed moves to the inside of the second positioning cylinder 8; it should be noted that in Figure 5In this state, the spring on the second clamping rod 12 is in a compressed state. When the left end of the bolt moves into the second positioning cylinder 8 and the first slider 10 moves to the left side of the second clamping block 12, the second clamping block 12 will move inward under the action of the spring to clamp the left end of the bolt. Then the laser generating device 2 can work again, and the external motor can drive the first positioning cylinder 6 and the second positioning cylinder 8 to drive the bolt to rotate synchronously. After the bolt rotates one more circle, the surface treatment of the smaller diameter end on the left side of the bolt is completed. At this time, the second driving mechanism will drive the second sliding plate 5 and the second positioning cylinder 8 to move leftward synchronously. The second positioning cylinder 8 will drive the bolt to move leftward synchronously through the second clamping block 12, so that the larger diameter end on the right side of the bolt is located directly above the laser generating device 2. Then the external motor can drive the bolt to rotate one more circle to complete the surface treatment of the entire bolt. Then the second driving mechanism drives the second sliding plate 5 to move back to the initial position to the right. At this time, the inclined surface of the trapezoidal push block 16 will drive the second limiting block 14 to move downward to cancel the limit on the first slider 10. Then the first slider 10 will move to the right under the elastic force of the compression spring 11. The first slider 10 will push the left end of the bolt out of the second positioning cylinder 8, enabling the bolt to automatically fall off after the surface treatment is completed. Through the setting of the first positioning cylinder 6, the first clamping block 7 and the clamping rod 9 in the present invention, the first positioning cylinder 6 can cooperate with the first clamping block 7 to position and fix the bolt. The clamping rod 9 can make the left end of the bolt located directly above the laser generating device 2, ensuring that the bolt can start surface treatment from the leftmost end. At the same time, through the setting of the second positioning cylinder 8, the first slider 10, the compression spring 11, the second clamping block 12 and the limiting mechanism, the limiting mechanism can cancel the limit on the first slider 10 after the bolt rotates one circle to complete one surface treatment. Then the left end of the bolt can enter the second positioning cylinder 8 and be clamped by the second clamping block 12. At this time, the second clamping block 12 replaces the first clamping block 7 to perform the clamping work, facilitating the subsequent surface treatment of the right end of the bolt. After the rust layer on the surface of the bolt is removed, the bolt can move out of the second positioning cylinder under the elastic force of the compression spring 11, enabling the next bolt surface treatment work to proceed faster.

[0028] As a further solution of the present invention, the first driving mechanism includes a first cylinder 17. The output end of the first cylinder 17 is fixedly connected to the first sliding plate 4, and the fixed end of the first cylinder 17 is fixedly connected to the support plate 3.

[0029] During operation, as Figure 4 shown, the first cylinder 17 can drive the first sliding plate 4 to reciprocate in the left - right direction.

[0030] As a further solution of the present invention, the second driving mechanism includes a first sliding groove 18, which is composed of two horizontal grooves and a vertical groove. The two ends of the vertical groove are smoothly connected to the ends of the two horizontal grooves respectively. A guiding column 19 is slidably connected in the first sliding groove 18. The guiding column 19 is fixedly connected to the second sliding plate 5. A square block 20 is fixedly connected to the outside of the guiding column 19. A second sliding block 21 is slidably connected to the square block 20 in the vertical direction. The second sliding block 21 is slidably connected to the support plate 3 in the horizontal direction. The second sliding block 21 is threadedly connected to a threaded rod 22, and the threaded rod 22 is rotatably connected to the support plate 3.

[0031] During operation, as Figure 2 and Figure 3 shown, when the surface treatment of the smaller diameter end on the left side of the bolt is completed, the threaded rod 22 is driven to rotate by an external motor. The threaded rod 22 will drive the second sliding block 21 to move to the left. The second sliding block 21 will drive the square block 20, the guiding column 19 and the second sliding plate 5 to move synchronously to the left. The guiding column 19 will slide in the first sliding groove 18. Through the setting of the inclined groove, the guiding column 19 can drive the second sliding plate 5 to move upward a small distance, so that the second sliding plate 5 drives the second positioning cylinder 8, the second clamping block 12 and the bolt to move downward a small distance synchronously, so that the distance between the larger diameter end surface on the right side of the bolt and the laser generating device 2 is the same as the distance between the left end surface and the laser generating device 2, which can ensure better rust removal treatment on the surface of the bolt, and at the same time can avoid over-treatment of the bolt surface caused by the decrease in the distance between the bolt surface and the laser generating device 2.

[0032] As a further solution of the present invention, a first traction rope 23 is fixedly connected to each of the first clamping blocks 7. One end of the first traction rope 23 away from the first clamping block 7 is fixedly connected to a third sliding block 24. The third sliding block 24 is slidably connected to the first positioning cylinder 6. A wedge-shaped push block 25 for driving its movement is arranged on the side of the third sliding block 24. The wedge-shaped push block 25 is elastically slidably connected to the first sliding plate 4. A second traction rope 26 is fixedly connected to the wedge-shaped push block 25. One end of the second traction rope 26 away from the wedge-shaped push block 25 is fixedly connected to a sliding rod 27. The sliding rod 27 is slidably connected to the first sliding plate 4.

[0033] During operation, as Figure 6 and Figure 7As shown, after the left end of the bolt has completed a surface treatment, the first cylinder 17 will drive the first slide plate 4 to move leftward by a certain distance, causing the left end of the bolt to move into the first positioning cylinder 6. When the first slide plate 4 moves to the leftmost position, the slide rod 27 will move rightward relative to the first slide plate 4 under the action of the support plate 3. The slide rod 27 will drive the wedge-shaped push block 25 to move towards one end close to the third slider 24 through the second traction rope 26. The wedge-shaped push block 25 will drive the third slider 24 to move to the right through the wedge surface. The third slider 24 will drive the first clamping block 7 to move outward through the first traction rope 23, canceling the fixation of the bolt by the first clamping block 7. Subsequently, the second positioning cylinder 8 and the second clamping block 12 drive the bolt to move leftward. When the left end of the bolt is directly below the laser generating device 2, the first clamping block 7 will not have a pulling effect on the bolt, avoiding displacement of the bolt under the action of the first clamping block 7, which may cause it to be unable to accurately move directly below the laser generating device 2.

[0034] As a further solution of the present invention, a loading platform 28 is provided above the workbench 1. The bottom of the loading platform 28 is fixedly connected to a second cylinder 29, and the second cylinder 29 is fixedly connected to the workbench 1.

[0035] The top of the loading platform 28 is provided with an inclined surface. A baffle 30 is rotatably installed at the lower end of the top of the loading platform 28. A torsion spring is sleeved on the rotating shaft of the baffle 30. A gear 31 is also fixedly connected to the rotating shaft of the baffle 30. A rack bar 32 that can mesh with the gear 31 is arranged on the side of the gear 31, and the rack bar 32 is fixedly connected to the workbench 1.

[0036] During operation, as Figure 4 and Figure 8 shown, when the bolt needs to be processed, the staff places the bolt to be processed on the top of the loading platform 28. Since the top surface of the loading platform 28 is an inclined surface that is higher at the back and lower at the front, the bolt will stop inside the baffle 30. At this time, the left end of the bolt is located on the left side of the first positioning cylinder 6. Then the first positioning cylinder 6 can move leftward to insert the bolt into the first positioning cylinder 6. When the bolt is undergoing surface treatment, the second cylinder 29 drives the loading platform 28 to move downward to the lower side of the bolt. At this time, the gear 31 will drive the baffle 30 to rotate downward under the action of the rack bar 32. After the bolt surface treatment is completed and the bolt falls onto the loading platform 28, the bolt can slide forward along the top surface of the loading platform 28.

[0037] As a further solution of the present invention, an air suction fan 33 is provided at the rear of the laser generating device 2.

[0038] During operation, as Figure 4 shown, through the setting of the air suction fan 33, the air suction fan 33 can timely discharge the harmful substances generated by the laser high-temperature treatment.
