Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of screw pump machining equipment, and more specifically, to a cutting device for screw pump machining. Background Technology

[0002] In the manufacturing of screw pumps, the machining of the universal joint at one end of the screw pump rotor is extremely critical. However, current machining equipment has significant shortcomings. Existing cutting devices cannot simultaneously complete the machining of the universal joint's inner diameter and drilling. When machining the universal joint's inner diameter, the rotor needs to be transferred from one set of equipment to another set of equipment specifically for inner diameter machining; after completing the inner diameter machining, it must be transferred again to drilling equipment for drilling operations.

[0003] This separate processing method not only increases processing steps and time costs, and reduces production efficiency, but also easily leads to rotor positioning deviations during multiple transfers, affecting processing accuracy.

[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0036] like Figures 1-4 As shown, a cutting device for machining a screw pump is illustrated in one embodiment of this disclosure, comprising:

[0037] The platform 1 and the column 2 are fixed to the surface of the platform 1;

[0038] Fixing component 4 is disposed on the surface of the stand 1;

[0039] The rectangular groove 3 and the cutting assembly 5 are provided. The rectangular groove 3 is formed on the surface of the frame 1, and the cutting assembly 5 is disposed in the rectangular groove 3.

[0040] Drilling assembly 6 is mounted on column 2;

[0041] The fixing component 4 includes a pair of telescopic cylinders 4-1, both of which are mounted on the bottom surface of the platform 1. The output end of the telescopic cylinders 4-1 is connected to a bracket 4-2. A pair of first movable rods 4-3 are provided at the bottom of the bracket 4-2. The lower end of the first movable rods 4-3 is movably fitted inside the platform 1. A pair of second movable rods 4-4 are movably fitted inside the platform 1. A pressure frame 4-5 is connected to the upper end of the second movable rods 4-4. Springs 4-6 are fitted on both the first movable rods 4-3 and the second movable rods 4-4. Racks 4-7 are provided on both outer surfaces of the bracket 4-2 and both inner surfaces of the pressure frame 4-5. A pair of fixing rods 4-8 are fixedly connected to the surface of the platform 1. Gears 4-9 are rotatably connected to the fixing rods 4-8. Gears 4-9 mesh between the racks 4-7 of the first movable rods 4-3 and the second movable rods 4-4.

[0042] In some examples, during the turning and drilling of the universal joint of the screw pump rotor, reliable clamping is required to ensure operational stability and accuracy. A fixing component 4 is designed, which includes a pair of telescopic cylinders 4-1 mounted on the bottom surface of the frame 1. When the telescopic cylinders 4-1 are activated, their output ends drive the bracket 4-2 connected to the output ends to move up and down. The universal joint of the rotor is placed on the bracket 4-2. A pair of first movable rods 4-3 are provided at the bottom of the bracket 4-2, with their lower ends movably fitted inside the frame 1. This allows the bracket 4-2 to maintain a stable movement trajectory during movement, avoiding deviation. A pair of movable rods 4-3 are movably fitted inside the frame 1. The second movable rod 4-4 has a pressure frame 4-5 connected to its upper end. Springs 4-6 are fitted on both the first movable rod 4-3 and the second movable rod 4-4. Springs 4-6 serve to buffer and reset. Racks 4-7 are provided on both outer surfaces of the bracket 4-2 and both inner surfaces of the pressure frame 4-5. Gears 4-9 are rotatably connected to a pair of fixed rods 4-8 fixedly connected to the surface of the platform 1. Gears 4-9 mesh between the racks 4-7 of the first movable rod 4-3 and the second movable rod 4-4. This transmission structure of gears 4-9 and racks 4-7 realizes the linkage between the first movable rod 4-3 and the second movable rod 4-4, so as to achieve the effect of clamping and fixing the universal joint together.

[0043] like Figures 1-4As shown, this embodiment proposes a cutting assembly 5 including a drive screw 5-1, which is rotatably connected in a rectangular groove 3. A movable stage 5-2 is slidably connected in the rectangular groove 3. A high-speed motor 5-3 is mounted on the movable stage 5-2. A rotary disk 5-4 is provided at the output end of the high-speed motor 5-3. A groove 5-5 is formed on the surface of the rotary disk 5-4. An adjusting screw 5-6 is rotatably connected in the groove 5-5. A slider 5-7 is vertically slidably connected in the groove 5-5. The slider 5-7 and the adjusting screw 5-6 are connected by a threaded connection. A mounting groove 5-8 is formed on the surface of the slider 5-7. A turning tool 5-9 is inserted into the mounting groove 5-8. Fixing bolts 5-10 are screwed to both sides of the slider 5-7. One end of the fixing bolt 5-10 is supported on both sides of the turning tool 5-9.

[0044] In some examples, during the machining of the universal joint inner diameter of a screw pump rotor, a cutting assembly 5 is designed to perform the machining operation on the universal joint inner diameter. This assembly includes a drive screw 5-1 rotatably connected within a rectangular slot 3, whose rotation is controlled by a motor. A movable stage 5-2, slidably connected within the rectangular slot 3, is threadedly connected to the drive screw 5-1. When the drive screw 5-1 rotates, the movable stage 5-2 moves linearly along the rectangular slot 3, thereby adjusting the horizontal position of the turning tool 5-9 so that it can accurately reach the part of the universal joint inner diameter that needs to be machined. A high-speed motor 5-3 is mounted on the movable stage 5-2, and a rotary disk 5-4 is located at the output end of the high-speed motor 5-3. Driven by the high-speed motor 5-3, the rotary disk 5-4 has an open surface. An adjusting screw 5-6 is rotatably connected within a groove 5-5. A slider 5-7, vertically slidable within the groove 5-5, is connected to the adjusting screw 5-6 via a threaded connection. When the adjusting screw 5-6 rotates, the slider 5-7 slides vertically up and down within the groove 5-5, thereby adjusting the position of the turning tool 5-9 in the vertical direction to meet the machining requirements of different inner diameters. A mounting groove 5-8 on the surface of the slider 5-7 is used to insert and connect the turning tool 5-9. After the turning tool 5-9 is installed in the mounting groove 5-8, the fixing bolts 5-10 on both sides of the slider 5-7 are tightened, so that one end of the fixing bolts 5-10 supports both sides of the turning tool 5-9, thus firmly fixing the turning tool 5-9 to the slider 5-7 and ensuring the stability of the tool and machining accuracy during the turning process.

[0045] For example Figures 1-4 As shown, this embodiment proposes a drilling assembly 6 including a second lead screw 6-1, which is rotatably connected inside the column 2. A lifting platform 6-2 is slidably connected inside the column 2. The lifting platform 6-2 and the second lead screw 6-1 are connected by a threaded connection. A second motor 6-3 is installed on the lifting platform 6-2. A drill bit 6-4 is installed at the output end of the second motor 6-3. Circular holes 6-5 are opened on the surfaces of the pressure frame 4-5 and the bracket 4-2.

[0046] In some examples, when drilling the universal joint clamped by the sleeve and bracket 4-2, a drilling assembly 6 is designed to achieve precise and efficient drilling operations. This assembly includes a second lead screw 6-1 rotatably connected inside the column 2, whose rotation is controlled by a motor. A lifting platform 6-2 slidably connected inside the column 2 is threadedly connected to the second lead screw 6-1. When the second lead screw 6-1 rotates, the lifting platform 6-2 moves linearly along the column 2 in the vertical direction, thereby adjusting the vertical position of the drill bit 6-4 so that it can accurately reach the part of the universal joint that needs drilling. The second motor 6-3 installed on the platform 6-2, and the drill bit 6-4 installed at the output end of the second motor 6-3, can rotate at high speed under the drive of the second motor 6-3 to drill the universal joint. The round holes 6-5 on the surfaces of the pressure frame 4-5 and the bracket 4-2 provide guidance and clearance space for the drilling path of the drill bit 6-4. After the sleeve and the bracket 4-2 clamp the universal joint, the drill bit 6-4 can accurately align with the position to be drilled on the universal joint through these round holes 6-5, avoiding interference between the drill bit 6-4 and the pressure frame 4-5 and the bracket 4-2 during the drilling process, and ensuring the smooth progress of drilling.

[0047] For example, such as Figure 1 As shown, both bracket 4-2 and pressure bracket 4-5 have V-shaped structures with arc transitions on their surfaces.

[0048] In some examples, the V-shaped structure allows the bracket 4-2 and the pressure bracket 4-5 to clamp universal joints of varying diameters and keep them in a centered position.

[0049] For example, such as Figure 4 As shown, a screw block 7 is provided at the lower end of the adjusting screw 5-6. The screw block 7 has a polygonal structure.

[0050] In some examples, the height position of the turning tools 5-9 is easily adjusted manually by setting up a polygonal screw block 7.

[0051] For example, such as Figure 1 As shown, a roller frame 8 is provided on the surface of the stand 1.

[0052] In some examples, a roller frame 8 is provided to facilitate rotor support and material feeding.

[0053] In actual use: Place the universal joint of the screw pump rotor on the bracket 4-2, start the telescopic cylinder 4-1 of the fixing component 4, the bracket 4-2 rises, and through the cooperation of the first movable rod 4-3, the second movable rod 4-4, the spring 4-6, the rack 4-7 and the gear 4-9, the pressure frame 4-5 presses the universal joint. According to the machining requirements of the universal joint's inner diameter, rotate the adjusting screw 5-6 to adjust the position of the turning tool 5-9 and fix it. Start the drive screw 5-1 motor and the high-speed motor 5-3 of the cutting component 5. The moving table 5-2 drives the turning tool 5-9 to cut the inner diameter of the universal joint. After the inner diameter is machined, start the second screw 6-1 motor and the second motor 6-3 of the drilling component 6. The lifting table 6-2 drives the drill bit 6-4 to descend, and drill through the round hole 6-5 on the bracket 4-2 and the pressure frame 4-5 to machine the universal joint.
