Description

A drilling and grinding device for split-type end cap processing Technical Field

[0001] This utility model relates to the field of end cap processing technology, specifically a drilling and grinding device for split-type end cap processing. Background Technology

[0002] A head is a component used to seal the end of a container and isolate it from the internal and external media. It is also called an end cap. Split heads are usually composed of two or more parts, which are processed separately and then assembled and welded to form a complete head.

[0003] After the split-type head is formed, holes need to be drilled in the flanges. After drilling, the holes are ground sequentially using a grinding device. To reduce workload, the conventional drilling device currently stacks the split head parts one on top of the other and drills them together. However, this device can only drill holes on the same circumference and cannot drill holes on different circumferences (inner and outer layers of the flange) simultaneously. At the same time, the multi-layered head section places extremely high demands on the strength of the drill bit and the stability of the drilling equipment. Excessive load can easily damage the drilling equipment, thus affecting the efficiency of post-processing of the head.

[0004] To address the aforementioned problems, we propose a drilling and grinding device for split-type end cap processing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a drilling and grinding device for split-type end cap processing, which can drill holes in positions that are not on the same circle, and can perform drilling and grinding in one step, thus solving problems such as low processing efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including an outer frame and a sliding rail fixedly disposed below the outer frame, a placement platform slidably disposed above the sliding rail, a plurality of downward holes being formed on the upper surface of the placement platform, the downward holes penetrating the placement platform; the placement platform is also provided with clamps for fixing the various components of the split-type end cap;

[0007] A partition is fixedly installed in the middle of the outer frame. The partition has several lifting holes. A cylinder is fixedly installed on the upper surface of the partition. The output end of the cylinder is fixedly connected to the lifting frame. Several lifting columns are fixedly installed on the upper surface of the lifting frame. The lifting columns pass through the lifting frame. A drill bit is fixedly installed at the lower end of the lifting column. A grinding block is sleeved on the outside of the lifting column. The grinding block is located above the drill bit and below the lifting frame.

[0008] Preferably, there are at least eight lifting columns, each of which is located directly above a corresponding lifting hole. The lifting hole is slightly larger than the drill bit and the grinding block, and each lifting hole corresponds to the downward hole.

[0009] Preferably, the lifting columns are arranged in groups of four, with a lower gear fixedly fitted on the outer side of each lifting column in one group, and an upper gear fixedly fitted on the outer side of each lifting column in the other group.

[0010] Preferably, the lower gear is located below the upper gear, and both the lower gear and the upper gear are located inside the lifting frame.

[0011] Preferably, the four lower gears mesh with the lower main gear, the four upper gears mesh with the upper main gear, the lower main gear is fixedly connected to the rotating shaft, and the upper main gear is fixedly connected to the rotating shaft.

[0012] Preferably, a motor frame is fixedly installed on the upper surface of the lifting frame, and a motor is fixedly installed inside the motor frame, with the output end of the motor fixedly connected to the rotating shaft.

[0013] Preferably, the upper end of the lifting column is rotatably connected to a fixing ring, and the fixing ring is fixedly disposed on the upper surface of the lifting frame.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Embodiments

[0024] Please refer to Figures 1-4. In this embodiment, a drilling and grinding device for processing a split-type end cap includes an outer frame 3 and a sliding rail 2 fixedly disposed below the outer frame 3. A placement platform 1 is slidably disposed above the sliding rail 2. The upper surface of the placement platform 1 has a plurality of downward holes 18, which pass through the placement platform 1. The placement platform 1 is also provided with clamps for fixing the various components of the split-type end cap.

[0025] A partition 19 is fixedly installed in the middle of the outer frame 3. Several lifting holes 4 are provided through the partition 19. A cylinder 16 is fixedly installed on the upper surface of the partition 19. The output end of the cylinder 16 is fixedly connected to the lifting frame 10. Several lifting columns 5 are fixedly installed on the upper surface of the lifting frame 10. The lifting columns 5 pass through the lifting frame 10. A drill bit 17 is fixedly installed at the lower end of the lifting column 5. A grinding block 6 is sleeved on the outside of the lifting column 5. The grinding block 6 is located above the drill bit 17 and below the lifting frame 10.

[0026] Before operating the drilling and grinding device for the split-type end cap, the operator needs to place each component of the split-type end cap into the fixture on the placement table 1 and fix it in place; then push the placement table 1 to slide along the sliding rail 2 into the inner frame 3. At this time, each downward hole 18 is exactly located directly below the corresponding lifting hole 4. At this time, the drilling and grinding device for the split-type end cap is started.

[0027] Driven by the motor 14, the lifting column 5 rotates, causing the drill bit 17 to rotate and the grinding block 6 to rotate. At this time, the lifting frame 10 descends under the drive of the cylinder 16. Based on the fixed position of the upper end of the lifting column 5 and the lifting frame 10, the lifting column 5 descends, causing the grinding block 6 to descend, allowing the drill bit 17 to pass through the lifting hole 4 opened on the upper surface of the partition 19, allowing the drill bit 17 to drill through the component block and pass into the lower hole 18. At this time, the grinding block 6 reaches the inside of the drill hole through the lifting hole 4 for grinding. After the drill bit 17 drills the hole, the grinding block 6 grinds accordingly, achieving the effect of integrated drilling and grinding, thereby improving processing efficiency. Furthermore, based on the design of two sets of lifting columns 5, and driven by the upper main gear 12 and the lower main gear 11 respectively, the effect of drilling holes at different circumferential positions at the same time is achieved, further improving processing efficiency.

[0028] There are at least eight lifting columns 5, each of which is located directly above the corresponding lifting hole 4. The lifting hole 4 is slightly larger than the drill bit 17 and the grinding block 6. Each lifting hole 4 corresponds to the downward hole 18.

[0029] The lifting columns 5 are arranged in groups of four. Each group of lifting columns 5 has a lower gear 7 fixedly fitted on its outer side, and the other group of lifting columns 5 has an upper gear 8 fixedly fitted on its outer side.

[0030] The lower gear 7 is located below the upper gear 8, and both the lower gear 7 and the upper gear 8 are located inside the lifting frame 10.

[0031] Four lower gears 7 mesh with the lower main gear 11, and four upper gears 8 mesh with the upper main gear 12. The lower main gear 11 is fixedly connected to the rotating shaft 15, and the upper main gear 12 is fixedly connected to the rotating shaft 15.

[0032] A motor frame 13 is fixedly installed on the upper surface of the lifting frame 10. A motor 14 is fixedly installed inside the motor frame 13, and the output end of the motor 14 is fixedly connected to the rotating shaft 15.

[0033] The upper end of the lifting column 5 is rotatably connected to the fixing ring 9, and the fixing ring 9 is fixedly set on the upper surface of the lifting frame 10;

[0034] When the drilling and grinding device for the split-type end cap processing is started, the rotating shaft 15 rotates under the drive of the motor 14. Based on the simultaneous fixed connection between the rotating shaft 15 and the upper main gear 12 and the lower main gear 11, the upper main gear 12 and the lower main gear 11 rotate simultaneously. Furthermore, based on the four lower gears 7 meshing with the lower main gear 11 and the four upper gears 8 meshing with the upper main gear 12, all the lower gears 7 and all the upper gears 8 rotate simultaneously, all the lifting columns 5 rotate simultaneously, and the grinding block 6 and the drill bit 17 rotate simultaneously.

[0035] At this time, the lifting frame 10 descends under the drive of the cylinder 16. Based on the rotational connection between the upper end of the lifting column 5 and the fixed ring 9, and the fixed ring 9 and the lifting frame 10 are fixedly connected, the lifting column 5 and the lifting frame 10 are limited to the same horizontal position, so that the lifting column 5 descends, the grinding block 6 and the drill bit 17 descend at the same time to contact the block and complete the grinding.

[0036] Based on the fixed connection between the motor frame 13 and the lifting frame 10, and the motor 14 being fixedly installed inside the motor frame 13, the motor 14 is confined and will not fall off or rotate on its own.

[0037] By setting the diameter of the grinding block 6 to match the maximum point of the drill bit 17, the grinding block can contact the inner surface of the drill hole, thereby grinding the drill hole.

[0038] By setting two main gears, drill bit 17 can simultaneously drill holes at different circumferences, allowing the end cap to have two rings of holes drilled in one process, providing mounting holes of two different specifications for the end cap and improving its installation strength.

[0039] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0040] Any connection method that can achieve its beneficial effect can be implemented, so the specific structural composition and working principle will not be described in detail in this embodiment.
