Description

Technical Field

[0001] This utility model relates to the technical field of tank drilling devices, specifically a tank drilling device for pressure vessel production. Background Technology

[0002] In the production of pressure vessels, tank drilling is a crucial step that directly affects product quality and production efficiency. However, traditional tank drilling operations commonly suffer from poor tank fixation, which not only impacts drilling accuracy and efficiency but also poses a potential safety hazard to operators.

[0003] Traditional tank drilling devices mostly use simple clamps or pressure plates to fix the tank. This fixing method often lacks sufficient flexibility and adaptability, making it difficult to adapt to tanks of different sizes and shapes. At the same time, due to the limited number of fixing points, the tank is prone to shaking or shifting during the drilling process, resulting in inaccurate drilling positions and even damage to the tank. Utility Model Content

[0004] The purpose of this utility model is to provide a tank drilling device for pressure vessel production, in order to solve the problem mentioned in the background art that most traditional tank drilling devices use simple clamps or pressure plates to fix the tank. This fixing method often lacks sufficient flexibility and adaptability, and is difficult to adapt to tanks of different sizes and shapes. At the same time, due to the limited number of fixing points, the tank is prone to shaking or displacement during the drilling process, resulting in inaccurate drilling position and even damage to the tank.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tank drilling device for pressure vessel production, comprising a base, a side-end drilling device body fixedly installed on one side of the top of the base, a placement platform provided on the other side of the top of the base, a tank body placed at the center of the top of the placement platform, and arc-shaped clamps slidably connected to both sides of the top of the placement platform, the inner walls of the opposite sides of the two arc-shaped clamps contacting the outer side of the tank body, side plates fixedly connected to both sides of the top of the placement platform, movable plates provided at the top of the opposite sides of the two side plates, and arc-shaped fixing plates fixedly connected to the top of the opposite ends of the two movable plates, the side of the arc-shaped fixing plate away from the movable plate contacting the outer surface of the tank body, cylinders fixedly installed on the top of the opposite sides of the two side plates, push rods fixedly connected to the output ends of the opposite sides of the two cylinders, and the opposite sides of the two push rods respectively penetrating to one side of the two side plates and fixedly connected to the opposite sides of the two movable plates.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This pressure vessel manufacturing tank drilling device achieves multi-point, all-around fixation of the tank body through the design of arc-shaped clamping plates and arc-shaped fixing plates on the movable plate. Both the arc-shaped clamping plates and the movable plate can be slidably adjusted according to the tank size. The accuracy and stability of the fixing position are ensured by the interlocking structure of support rods, locking blocks, and locking slots. A cylinder-driven push rod moves the movable plate, which in turn causes the arc-shaped fixing plate to fit tightly against the tank body. This dynamic adjustment mechanism greatly enhances the device's flexibility and adaptability to tanks of different sizes and shapes. The arc-shaped clamping plates and the arc-shaped fixing plates on the movable plate are tightly fitted to the outer surface of the tank body. The close contact creates multi-point support, effectively reducing the shaking or displacement of the tank during the drilling process. The sliding connection structure between the support rod and the movable plate and side plate, as well as the snap-fit ​​between the locking block and the slot, further enhances the stability of the fixation and ensures the accuracy of the drilling position. The even distribution of the arc-shaped clamping plate and the arc-shaped fixing plate on the movable plate achieves uniform pressure on the outer surface of the tank body, avoiding tank deformation or cracks caused by uneven fixing force. The precise control of the cylinder allows the fixing force of the arc-shaped fixing plate on the tank body to be flexibly adjusted, thereby further optimizing the distribution of fixing force.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a tank drilling device for pressure vessel production, including a base 1, a side-end drilling device body 2 fixedly installed on one side of the top of the base 1, a placement platform 3 provided on the other side of the top of the base 1, a tank body 4 placed at the center of the top of the placement platform 3, and arc-shaped clamping plates 5 slidably connected to both sides of the top of the placement platform 3, with the inner walls of the opposite sides of the two arc-shaped clamping plates 5 contacting the outer side of the tank body 4. Side plates 14 are fixedly connected to both sides of the top of the placement platform 3. On the opposite sides of the two side plates 14, near the top, there are movable plates 15. At the top of the opposite ends of the two movable plates 15, there are fixed arc-shaped fixing plates 17. The side of the arc-shaped fixing plate 17 away from the movable plate 15 is in contact with the outer surface of the tank body 4. On the top of the opposite side of the two side plates 14, there are fixed cylinders 16. The output ends of the opposite side of the two cylinders 16 are fixedly connected to push rods 21. The opposite side of the two push rods 21 passes through to one side of the two side plates 14 and is fixedly connected to the opposite side of the two movable plates 15.

[0015] Support rods 20 are fixedly connected to the top of the two arc-shaped clamping plates 5 on opposite sides. The side of the support rods 20 away from the arc-shaped clamping plates 5 passes through the movable plate 15 and the side plate 14 in sequence and extends to the outside of the side plate 14. The support rods 20 are sleeved and slidably connected to the movable plate 15 and the side plate 14.

[0016] The top of the two curved clamping plates 5 opposite to each other is provided with slots 18 above and below the support rod 20. Two locking blocks 19 are fixedly connected to the bottom of the two movable plates 15 opposite to each other. The side of the locking block 19 away from the movable plate 15 extends into the inside of the slot 18 and engages with the slot 18.

[0017] A groove 6 is provided in the center of the base 1, and a central column 7 is fixedly connected to the center of the bottom of the platform 3. The bottom of the central column 7 extends through the inside of the groove 6 and is rotatably connected to the bottom of the groove 6.

[0018] A variable frequency motor 8 is fixedly installed on one side of the base 1. A rotating rod 9 is fixedly connected to the output end of one side of the variable frequency motor 8. One side of the rotating rod 9 extends into the interior of the groove 6 and is fixedly connected to a longitudinal gear 11. A transverse gear 10 is fixedly connected to the bottom of the central column 7. One side of the top of the transverse gear 10 meshes with the bottom of one side of the longitudinal gear 11.

[0019] The top of the base 1 is provided with an annular groove 12 corresponding to the bottom of the placement platform 3. An annular slide plate 13 is fixedly connected to the outer side of the bottom of the placement platform 3. The bottom of the annular slide plate 13 extends through the interior of the annular groove 12 and is slidably connected to the annular groove 12.

[0020] Working principle: First, the can body 4 to be drilled is placed in the center of the placement platform 3. Then, the motor on one side of the placement platform 3 is started, sliding two arc-shaped clamping plates 5 so that their inner walls on opposite sides are in close contact with the outer side of the can body 4, achieving initial fixation of the can body 4. The cylinder 16 is started, and its output end pushes the push rod 21 forward. The push rod 21 drives the movable plate 15 to move towards the can body 4, thereby making the arc-shaped fixing plate 17 tightly adhere to the outer surface of the can body 4, enhancing the fixing effect. During the movement of the movable plate 15, the support rod 20 slides within the movable plate 15 and the side plate 14 to ensure the smooth movement of the movable plate 15. When the arc-shaped fixing plate 17 is completely in contact with the can body 4, the locking block 19 will enter the locking groove 18 to achieve locking and fixation, preventing the movable plate 15 and the arc-shaped clamping plate 5 from moving during the drilling process. The frequency conversion motor 8 is started, and its output end drives the rotating rod 9 to rotate. The longitudinal gear 11 on the rotating rod 9 engages with the transverse gear at the bottom of the central column 7. Wheel 10 engages, thereby driving the central column 7 and the placement platform 3 to rotate around their axis. The annular slide plate 13 at the bottom of the placement platform 3 slides in the annular groove 12 at the top of the base 1, ensuring that the placement platform 3 rotates smoothly. By controlling the speed and direction of the variable frequency motor 8, the rotation angle of the can body 4 can be precisely adjusted to achieve the optimal drilling position. When the can body 4 rotates to the predetermined position, the side drilling device body 2 starts. The side drilling device body 2 performs drilling operation on the can body 4 according to the preset drilling parameters and program. After drilling is completed, the side drilling device body 2 stops working and waits for the next drilling command. After drilling is completed, the cylinder 16 starts in reverse, pushing the push rod 21 and the movable plate 15 to reset, so that the arc-shaped fixing plate 17 is separated from the can body 4. The motor set on one side of the placement platform 3 starts, loosens the arc-shaped clamp 5, takes out the drilled can body 4, places the new can body 4 on the placement platform 3, and repeats the above-mentioned fixing, rotation positioning and drilling operations.

[0021] In summary, this pressure vessel production tank drilling device, through the design of the arc-shaped clamping plate 5 and the arc-shaped fixing plate 17 on the movable plate 15, achieves multi-point, all-round fixation of the tank body 4. Both the arc-shaped clamping plate 5 and the movable plate 15 can be slidably adjusted according to the tank size. The locking structure of the support rod 20, the locking block 19, and the locking groove 18 ensures the accuracy and stability of the fixing position. The cylinder 16 drives the push rod 21 to move the movable plate 15, thereby causing the arc-shaped fixing plate 17 to fit tightly against the tank body 4. This dynamic adjustment mechanism greatly enhances the flexibility and adaptability of the device to tanks of different sizes and shapes. The arc-shaped clamping plate 5 and the arc-shaped fixing plate 17 on the movable plate 15 fit tightly against the tank body 4. The outer surface of the body 4 is in close contact, forming multi-point support, which effectively reduces the shaking or displacement of the tank during the drilling process. The sliding connection structure between the support rod 20 and the movable plate 15 and the side plate 14, as well as the engagement between the locking block 19 and the locking groove 18, further enhance the stability of the fixation and ensure the accuracy of the drilling position. Through the uniform distribution of the arc-shaped clamping plate 5 and the arc-shaped fixing plate 17 on the movable plate 15, uniform pressure is applied to the outer surface of the tank body 4, avoiding tank deformation or cracks caused by uneven fixing force. The precise control of the cylinder 16 allows the fixing force of the arc-shaped fixing plate 17 on the tank body 4 to be flexibly adjusted, thereby further optimizing the distribution of fixing force.
