Description

Technical Field

[0001] This application relates to the field of propeller processing technology, and in particular to an adjustment structure for propeller processing. Background Technology

[0002] Propellers are mainly used in equipment such as centrifuges and single screw pumps to achieve solid-liquid separation or conveying of high-viscosity materials. When manufacturing propellers, it is necessary to ensure the coaxiality of the hollow shaft and the threaded blades; otherwise, it will lead to increased vibration, accelerated wear, or thrust deviation.

[0003] In the existing propeller manufacturing process, the hollow shaft and threaded plate are usually welded together to form the propeller. After welding, the propeller is placed on a fixed support structure and the two ends of the hollow shaft are fixed. Then, the coaxiality of the propeller is adjusted to ensure the coaxiality of the hollow shaft and the threaded plate.

[0004] The existing technical solutions mentioned above have the following drawbacks: the fixed support structure makes it inconvenient to adjust the height, and it is inconvenient to adjust the position of the propeller during processing, resulting in low flexibility. Utility Model Content

[0005] This application provides an adjustment structure for propeller machining to facilitate position adjustment and improve flexibility during propeller machining.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] An adjustment structure for propeller processing includes a housing, a housing plate connected to the top of the housing, slide rails fixedly connected to both the housing body and the housing plate, sliders slidably arranged on the slide rails, at least two sliders spaced apart, threaded cylinders fixedly connected to the sliders, threaded rods threadedly connected to the threaded cylinders, a connecting rod fixedly connected to one end of the threaded rods, and a top block connected to one end of the connecting rods.

[0008] By adopting the above technical solution, the slider is pushed to move on the slide rail, thereby driving the top block connected to the slider to move within the housing. This facilitates adjusting the position of the top block according to the size of the pusher to be processed, and makes it easier to process pushers of different sizes using the adjustment structure, thus improving flexibility. Rotating the connecting rod drives the threaded rod to rotate within the threaded cylinder, which can adjust the distance between the top block and the housing, thereby adjusting the position of the pusher within the adjustment structure. This facilitates adjusting the position of the pusher during processing and improves flexibility.

[0009] Optionally, a fixed cylinder is rotatably mounted on the threaded cylinder, the axis of the fixed cylinder is not on the same straight line as the axis of the threaded cylinder, a clamping cylinder is fixedly connected inside the fixed cylinder, the axis of the inner wall of the clamping cylinder is not on the same straight line as the axis of the outer wall, and the clamping cylinder is sleeved on a section of the connecting rod.

[0010] By adopting the above technical solution, rotating the fixed cylinder causes the clamping cylinder to rotate until the axis of the inner wall of the clamping cylinder is on the same straight line as the axis of the connecting rod. At this time, the connecting rod can be rotated to drive the threaded rod to rotate inside the threaded cylinder, thereby adjusting the position of the top block in the box. After adjustment, rotating the fixed cylinder causes the clamping cylinder to rotate until the axis of the inner wall of the clamping cylinder is away from the axis of the connecting rod. At this time, the inner wall of the clamping cylinder abuts against the peripheral wall of the connecting rod to fix the connecting rod, ensuring the stability of the position of the connecting rod and the top block in the box, and ensuring the stability of the adjustment structure operation.

[0011] Optionally, the slide rail is machined with limiting teeth, and a rack that meshes with the limiting teeth is embedded in the slider. A limiting bolt is passed through the slider and is threaded to the slider. One end of the limiting bolt abuts against the rack.

[0012] By adopting the above technical solution, after moving the slider, rotating the limiting bolt causes the rack to extend out of the slider and mesh with the limiting teeth, which can reduce the risk of the slider sliding on the slide rail during processing and causing the propeller to move, and ensure the stability of the adjustment structure for fixing the propeller.

[0013] Optionally, a positioning post is provided on the top of the box body, the positioning post passes through the box plate, and a fixing bolt for fixing the box plate is connected to the internal thread of the positioning post.

[0014] By adopting the above technical solution, the positioning column makes it easy to place the box panel in the corresponding position on the box body, increasing the stability of the connection between the box panel and the box body.

[0015] Optionally, a reinforcing plate is fixedly connected inside the box.

[0016] By adopting the above technical solution, the reinforcing plate inside the box can increase the overall structural strength of the box, ensure the stable fixation of the adjustment structure to the propeller, and ensure the overall safety and stability of the adjustment structure.

[0017] Optionally, the peripheral wall of the threaded cylinder is fixedly connected to a reinforcing rib, which is fixedly connected to the slider.

[0018] By adopting the above technical solution, the reinforcing ribs on the peripheral wall of the threaded cylinder can increase the stability of the connection between the threaded cylinder and the slider, and improve the stability of the adjustment structure for the propeller support.

[0019] Optionally, the housing is provided with air vents.

[0020] By adopting the above technical solution, the vents facilitate the discharge of dust and exhaust gas from the chamber during processing.

[0021] Optionally, one end of the connecting rod is fixedly connected to a mounting plate, and the mounting plate is fixedly connected to the top block.

[0022] By adopting the above technical solution, the top block is fixed to the mounting plate with bolts, which facilitates the maintenance and replacement of the top block by the staff, and makes it easy to use the adjustment structure to process thrusters of different sizes, thereby improving flexibility.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up a slide rail, slider, threaded cylinder and threaded rod, the slider moves on the slide rail to drive the top block connected to the slider to move in the box, which makes it easy to adjust the position of the top block according to the size of the pusher to be processed, and to use the adjustment structure to process pushers of different sizes, improving flexibility. Rotating the connecting rod drives the threaded rod to rotate in the threaded cylinder, which can adjust the distance between the top block and the box, thereby adjusting the position of the pusher in the adjustment structure, which makes it easy to adjust the position of the pusher during processing, improving flexibility.

[0025] 2. By setting up a fixed cylinder and a clamping cylinder, rotating the fixed cylinder causes the clamping cylinder to rotate until the axis of the inner wall of the clamping cylinder is on the same straight line as the axis of the connecting rod. At this time, the connecting rod can be rotated to drive the threaded rod to rotate inside the threaded cylinder to adjust the position of the top block in the box. After adjustment, rotating the fixed cylinder causes the clamping cylinder to rotate until the axis of the inner wall of the clamping cylinder is away from the axis of the connecting rod. At this time, the inner wall of the clamping cylinder abuts against the peripheral wall of the connecting rod to fix the connecting rod, ensuring the stability of the position of the connecting rod and the top block in the box, and ensuring the stability of the adjustment structure.

[0026] 3. By setting limit teeth, racks and limit bolts, after moving the slider, rotating the limit bolts causes the rack to extend out of the slider and mesh with the limit teeth, which can reduce the risk of the slider sliding on the slide rail during processing and causing the propeller to move, and ensure the stability of the adjustment structure for fixing the propeller.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses an adjustment structure for propeller processing, referring to... Figure 1 The adjustment structure includes a box body 1, which is rectangular in shape. The top of the box body 1 is open. Both sides of the box body 1 along its length are provided with processing openings 11. The processing openings 11 are U-shaped and connect to the top of the box body 1. Both sides of the box body 1 along its length are provided with air holes 12. Multiple air holes 12 are provided along the side walls of the box body 1 at intervals. The top of the box body 1 has four integrally formed positioning posts 14. The top of the box body 1 is connected to a box panel 13. The surface of the box panel 13 is rectangular. The box panel 13 can cover the open top of the box body 1, and the four corners of the panel are respectively fitted onto the four positioning posts 14. The end of the positioning post 14 away from the box body 1 passes through the box panel 13 and is provided with a fixing bolt 15. The large end of the fixing bolt 15 is attached to the side of the box panel 13 away from the box body 1.

[0032] Reference Figure 1 and Figure 2 A reinforcing plate 16 is welded inside the box body 1. The surface of the reinforcing plate 16 is triangular. The two sides of the reinforcing plate 16 are respectively connected to the bottom surface and the side wall inside the box body 1. Four reinforcing plates 16 are arranged at intervals inside the box body 1. A slide rail 2 is welded inside the box body 1. The slide rail 2 is arranged along the length direction of the box body 1. There are four slide rails 2, which are respectively located on the bottom surface, the top surface, and the side walls on both sides of the length direction of the box body 1. A slider 3 is fitted on the slide rail 2. The slider 3 is slidably connected to the slide rail 2. Three sliders 3 are arranged at intervals along the slide rail 2.

[0033] Reference Figure 1 and Figure 2 A threaded cylinder 4 is welded to the side of the slider 3 away from the slide rail 2. A reinforcing rib 41 is welded to the peripheral wall of the threaded cylinder 4 near the slider 3. Four reinforcing ribs 41 are spaced apart along the peripheral wall of the threaded cylinder 4. The section of the reinforcing rib 41 near the slider 3 is welded to the slider 3. An internal thread is formed on the inner wall of the threaded cylinder 4. A threaded rod 5 is connected to the internal thread of the threaded cylinder 4. One end of the threaded rod 5 extends out of the threaded cylinder 4 and is welded to a connecting rod 6. A mounting plate 7 is welded to the end of the connecting rod 6 away from the threaded rod 5. One side of the mounting plate 7 is welded to one end of the connecting rod 6, and a top block 8 is fixed to the other side of the plate by bolts.

[0034] Reference Figure 2A fixed cylinder 42 is rotatably connected to the end of the threaded cylinder 4 away from the slider 3. The fixed cylinder 42 is rotatably set near the edge of the end face of the threaded cylinder 4. The axis of the fixed cylinder 42 is not on the same straight line as the axis of the threaded cylinder 4. A clamping cylinder 43 is welded to the inner wall of the fixed cylinder 42 away from the threaded cylinder 4. The clamping cylinder 43 is sleeved on the section of the connecting rod 6 near the threaded cylinder 4. The axis of the inner wall of the clamping cylinder 43 is not on the same straight line as the axis of the outer wall of the clamping cylinder 43. The diameter of the inner wall of the clamping cylinder 43 is larger than the diameter of the connecting rod 6. When the axis of the inner wall of the clamping cylinder 43 is on the same straight line as the axis of the threaded cylinder 4, the inner wall of the clamping cylinder 43 is away from the peripheral wall of the connecting rod 6. When the axis of the inner wall of the clamping cylinder 43 is away from the axis of the threaded cylinder 4, the inner wall of the clamping cylinder 43 on the side near the connecting rod 6 is in contact with the peripheral wall of the connecting rod 6. A limiting cylinder 44 is welded to the inner wall of the fixed cylinder 42 away from the threaded cylinder 4. The end of the limiting cylinder 44 away from the fixed cylinder 42 abuts against the mounting plate 7.

[0035] Reference Figure 2 The sidewalls on both sides of the top length of the slide rail 2 are machined to form limiting teeth 21. The slider 3 is embedded with a rack 31 that meshes with the limiting teeth 21. There are two racks 31, which correspond one-to-one with the two limiting teeth 21. A limiting bolt 32 is threaded into the slider 3. One end of the limiting bolt 32 abuts against the side of the rack 31 away from the limiting teeth 21.

[0036] When using this adjustment structure, rotating the fixing bolt 15 releases the restriction on the box plate 13 and removes the box plate 13, making it easier to place the pusher inside the adjustment structure. The reinforcing plate 16 inside the box 1 increases the overall structural strength of the box 1, ensuring the adjustment structure can stably fix the pusher, and ensuring the overall safety and stability of the adjustment structure. The machining port 11 on the box 1 facilitates the worker to process the pusher. The vent 12 helps to discharge dust and exhaust gas from the box 1 during processing. The box plate 13 is placed on top of the box 1 and fixed with the fixing bolt 15. The positioning column 14 facilitates the placement of the box plate 13 in the corresponding position on the box 1, increasing the stability of the connection between the box plate 13 and the box 1. The multiple top blocks 8 abut against the hollow shaft of the pusher, which can fix the pusher inside the adjustment structure, making it easier to process the pusher. By rotating the connecting rod 6, the threaded rod 5 can be rotated inside the threaded cylinder 4, which can adjust the distance between the top block 8 and the box 1 to adjust the position of the pusher inside the adjustment structure, making it easier to adjust the position of the pusher during processing and improving flexibility.

[0037] The slider 3 is moved along the slide rail 2, causing the top block 8 connected to the slider 3 to move within the housing 1. This allows for adjustment of the position of the top block 8 according to the size of the pusher to be processed, facilitating the processing of pushers of different sizes using the adjustment structure and improving flexibility. After moving the slider 3, rotating the limiting bolt 32 causes the rack 31 to extend out of the slider 3 and engage with the limiting tooth 21. This reduces the risk of the pusher moving due to the slider 3 sliding on the slide rail 2 during processing, ensuring the stability of the adjustment structure in fixing the pusher.

[0038] The reinforcing ribs 41 on the periphery of the threaded cylinder 4 increase the stability of the connection between the threaded cylinder 4 and the slider 3, and improve the stability of the adjustment structure for supporting the propeller. Rotating the fixed cylinder 42 causes the clamping cylinder 43 to rotate until the axis of the inner wall of the clamping cylinder 43 is on the same straight line as the axis of the connecting rod 6. At this time, the connecting rod 6 can be rotated to drive the threaded rod 5 to rotate inside the threaded cylinder 4, thereby adjusting the position of the top block 8 inside the housing 1. After adjustment, rotating the fixed cylinder 42 causes the clamping cylinder 43 to rotate until the axis of the inner wall of the clamping cylinder 43 is away from the axis of the connecting rod 6. At this time, the inner wall of the clamping cylinder 43 abuts against the periphery of the connecting rod 6 to fix the connecting rod 6, ensuring the stability of the position of the connecting rod 6 and the top block 8 inside the housing 1, and ensuring the stability of the adjustment structure.

[0039] The top block 8 is fixed to the mounting plate 7 by bolts, which facilitates the maintenance and replacement of the top block 8 by the staff, and makes it easy to use the adjustment structure to process thrusters of different sizes, thus improving flexibility.
