[0016] 1. The present invention can be used in the grinding process of tank production, and is suitable for the grinding of annular and linear welds. The alignment process is accurate and fast, which greatly reduces the processing difficulty and improves the processing efficiency.

[0017] 2. The main frame is controlled to remain coaxial with the cylinder through the lifting mechanism, and the grinding rod moves to the position of the annular weld. Since the lower grinding rod is connected to structures such as the linear grinding mechanism, the gravity is significantly larger. Under the action of gravity, the grinding rod is driven downward until the grinding head contacts the annular weld. During the downward movement, the lower card plate moves downward, the slide seat translates along the inner side of the guide groove, the rotating rod rotates with the rotating shaft as the axis, and the upper grinding rod moves upward accordingly. Therefore, the upper and lower grinding rods move away from each other, and when the lower grinding head touches the bottom of the disk cylinder, the upper grinding head synchronously touches the top of the disk cylinder. When the lower grinding rod moves downward, the transmission plate and the clamping plate cooperate to make the grinding wheel move downward synchronously. When the grinding wheel moves down and touches the bottom, it contacts the linear weld, which can be better adapted to the grinding process of the tank body.

[0018] 3. In the subsequent movement process, the servo motor drives the threaded rod to rotate, so that the folding plate moves backward, and the upper side of the sleeve squeezes the pushing inclined surface to move the plug plate downward. After the perforation moves downward, it is coaxial with the plug column. At this time, under the elastic force of the compression spring, the plug column moves forward, driving the slide plate and the drive motor and other structures to move forward. When the plug rod moves forward, due to the mutual pushing and cooperation between the angle cutting head and the guide inclined surface, the plug rod can be inserted between the adjacent upper and lower limit protrusions, so that under the drive of the drive motor, the connecting shell rotates, and then the upper and lower grinding heads grind the annular weld. As the grinding proceeds, the grinding pressure on the surface of the annular weld can be guaranteed to ensure the grinding effect.

[0019] 4. Synchronously, as the folding plate moves backward, the grinding motor drives the grinding wheel to rotate, and the linear weld can be ground. During the forward movement of the folding plate, the convex teeth are inserted into the inner side of the tooth groove, locking the up and down movement of the mounting frame, keeping the grinding pressure unchanged during the linear movement, and completing the straight-line grinding process.

[0038] The moving mechanism includes a bracket 46 fixedly installed on the rear end of the main frame 1, and a servo motor 49 is fixedly installed on the rear surface of the bracket 46. The output shaft of the servo motor 49 is fixedly connected to a threaded rod 47. The threaded rod 47 rotates with the front surface of the bracket 46, and the threaded rod 47 passes through the inner side of the folding plate 33 and is threadedly engaged.

The guide rod 48 can increase the smoothness of the forward and backward movement of the folding plate 33.

[0039] A vehicle body 50 is arranged below the bracket 46. Obviously, the weight of the rear half of the vehicle body 50 needs to be sufficient to overcome the overturning moment at the main frame 1. The upper surface of the vehicle body 50 is installed with the bracket 46 through a lifting mechanism 51. The lifting mechanism 51 can be a hydraulic mechanism to control the up and down movement of the bracket 46. It is more common, and the specific structure of the lifting mechanism 51 will not be elaborated in detail.

[0040] The elastic mechanism includes an insertion cavity 3 opened on the inner side of the main frame 1, and a column 4 slidably inserted from the front end port of the insertion cavity 3. A compression spring 5 is arranged between the rear end of the column 4 and the inner wall of the insertion cavity 3. The front end of the column 4 is fixedly connected to the rear surface of the slide plate 2. A slide rail 13 is fixedly connected to the front lower edge of the main frame 1.

A plurality of return springs 11 are fixedly connected between the lower end surface of the anti-slip sheet 10 and the inner bottom surface of the active cavity 7. The anti-slip sheet 10 can prevent the lower end of the insert plate 8 from escaping from the inner side of the active cavity 7. A pushing slope 12 is formed on the front upper edge of the insert plate 8, and they push and cooperate with each other when the folding plate 33 moves backward.

[0042] The bidirectional deduction mechanism includes a rotating shaft 22 rotatably installed between the inner walls of both sides of the connecting shell 18, and a rotating rod 21 is fixedly sleeved on the outer surface of the rotating shaft 22. The front and rear ends of the rotating rod 21 are rotatably connected to the slide 20 through the connecting shaft 23 respectively. The surfaces of the upper and lower slides 20 that are separated from each other are slidably connected to the card-in plates 19 respectively. The outer surface of the card-in plate 19 is penetrated by a guide groove 25. The slide 20 is slidably inserted into the inner side of the guide groove 25 through a convex block 24 arranged on the outer surface. The edge of the card-in plate 19 is in sliding contact with the inner wall of the connecting shell 18 to ensure that the card-in plate 19 moves in the up and down directions.

[0043] The second locking mechanism includes a rotating disk 28 fixedly mounted at both ends of the rotating shaft 22, and two plug rods 16 fixedly connected to the front end surface of the driving disk 15. The front end of the plug rod 16 is provided with an angle cutting head 17, and the outer surface of the rotating disk 28 is provided with a ring array of limit protrusions 29. The end of the limit protrusion 29 is provided with an introduction inclined surface 30. When the driving disk 15 moves forward, the plug rod 16 slides through between the upper and lower limit protrusions 29. The outer surfaces of both sides of the connecting shell 18 are fixedly connected with I-shaped blocks 32 near the rear edge. The side of the plug rod 16 is penetrated by a side groove 31. The I-shaped block 32 is slidably inserted into the inner side of the side groove 31 to ensure that the plug rod 16 can be smooth relative to the connecting shell 18 to prevent the connecting shell 18 from falling off.

[0044] The linear grinding mechanism includes a mounting frame 43, a grinding motor 44 fixedly mounted at the lower end of the mounting frame 43, and a grinding wheel 45 fixedly mounted on the output shaft of the grinding motor 44. The mounting frame 43 is vertically slidably matched with the rear surface of the square cylinder 36. The front end of the mounting frame 43 is fixedly mounted on the card-in shell 41.

A plurality of convex teeth 38 are convexly provided on the two side walls of the square cylinder 36. A sharpening head 39 is provided at the rear end of the convex teeth 38. When the square cylinder 36 moves backward, the convex teeth 38 slide and snap into the inner side of the tooth groove 37.

A transmission plate 42 inserted between the two clamping plates 40 is fixedly mounted on the rear end surface of the grinding rod 26 below.

[0045] A sleeve 34 is formed through the rear end surface of the folding plate 33, and the sleeve 34 is slidably mounted on the outer surface of the main frame 1. Rollers 35 are respectively installed above and below the rear end surface of the folding plate 33 near the sleeve 34 to further improve the smoothness of the folding plate 33 when it moves horizontally.

[0046] When in use, the main frame 1 is controlled to remain coaxial with the cylinder body through the lifting mechanism 51, and the grinding rod 26 moves to the position of the annular weld. Since the lower grinding rod 26 is connected to the linear grinding mechanism and other structures, the gravity is obviously larger. Under the action of gravity, the grinding rod 26 is driven to move downward until the grinding head 27 contacts the annular weld. In the downward movement process, the lower card plate 19 moves downward, the slide seat 20 translates along the inner side of the guide groove 25, the rotating rod 21 rotates with the rotating shaft 22 as the axis, and the upper grinding rod 2 6 moves upward accordingly, so that the upper and lower grinding rods 26 move away from each other. When the lower grinding head 27 touches the bottom of the disc cylinder, the upper grinding head 27 synchronously touches the top of the disc cylinder. When the lower grinding rod 26 moves downward, the transmission plate 42 and the clamping plate 40 cooperate to make the grinding wheel 45 move downward synchronously. When the grinding wheel 45 moves downward and touches the bottom, it contacts the linear weld seam, which can be better adapted to the grinding process of the tank body. In the subsequent movement process, the servo motor 49 drives the threaded rod 47 to rotate, The folding plate 33 moves backward, and the upper side of the sleeve 34 squeezes the pushing inclined surface 12, so that the plug plate 8 moves downward, and the through hole 9 moves downward and becomes coaxial with the plug column 4. At this time, under the elastic force of the compression spring 5, the plug column 4 moves forward, driving the slide plate 2 and the drive motor 14 and other structures to move forward. When the plug rod 16 moves forward, due to the mutual pushing and cooperation between the angle cutting head 17 and the introduction inclined surface 30, the plug rod 16 can be inserted between the adjacent upper and lower limit protrusions 29, so that under the drive of the drive motor 14, the connecting shell 18 rotates, and then The upper and lower grinding heads 27 grind the annular weld. As the grinding proceeds, the grinding pressure on the surface of the annular weld can be guaranteed to ensure the grinding effect. Synchronously, as the folding plate 33 moves backward, the grinding motor 44 drives the grinding wheel 45 to rotate, so that the linear weld can be ground. During the forward movement of the folding plate 33, the convex teeth 38 are inserted into the inner side of the tooth grooves 37, locking the up and down movement of the mounting frame 43, keeping the grinding pressure unchanged during the linear movement, and completing the grinding process on the straight line.
