Description

Technical Field

[0001] This utility model relates to the field of guide vane machining technology, and in particular to a guide vane milling clamping device. Background Technology

[0002] Guide vanes are energy conversion devices used in hydraulic machinery such as centrifugal pumps and water turbines to convert the kinetic energy of liquid into pressure energy. They are mainly used in multi-stage centrifugal pumps. Their core function is to collect the liquid thrown out by the impeller, reduce the flow velocity through the diffuser-shaped flow channel, and realize the conversion of kinetic energy into static pressure energy. At the same time, they guide the fluid into the next stage impeller or outlet pipe. Guide vanes are classified into radial type and flow channel type according to their structure. The latter has better hydraulic performance due to its continuous flow channel design, but the manufacturing process is more complex, and special tools are required in the assembly process to ensure accuracy and avoid damage to the pump cavity.

[0003] Existing guide vane milling clamping devices, such as the one disclosed in application number CN202322071927.1, include a machine tool worktable, a tooling plate on top of the worktable, a limit plate fixed to the edge of the tooling plate, and a limit seat fixed to the surface of the worktable. A cap is provided above the limit seat, and a connecting rod is fixed to the surface of the limit seat. The connecting rod is located inside the cap, and a spiral spring is installed between the connecting rod and the cap. However, in the above technology, when machining is required, the impeller is usually clamped and mounted on the impeller shaft using a single set of fixtures. Because it is a single-set setup, errors are easily introduced after a single machining operation, which requires significant costs for subsequent adjustments. Moreover, it is not convenient to make timely adjustments based on the impeller's distribution density and spacing angle. Therefore, this utility model proposes a guide vane milling clamping device to solve the problems existing in the prior art. Utility Model Content

[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0015] according to Figure 1-6 As shown, this embodiment proposes a guide vane milling clamping device, including a mounting rotating component 1 and a blade clamping mechanism 4. The output end of the mounting rotating component 1 is provided with a pitch adjustment mechanism 2, and the two ends of the pitch adjustment mechanism 2 are provided with a hinged positioning rotating mechanism 3. The output end of the positioning rotating mechanism 3 is provided with a blade clamping mechanism 4. The blade clamping mechanism 4 includes an outer connecting bracket 401, a limiting plate 402, a bushing 403, a gear ring 404, a limiting guide wheel 405, a connecting plate 406, a second electric gear 407, a track bar 408, an insertion block 409, a sliding sleeve 4010, an electric guide wheel 4011, a pneumatic push rod 4012, an electric rotating seat 4013, a rotating arm 4014, and an electric clamp 4015. Eight sets of outer connecting brackets 401 are arranged at equal angles on the outer sides of both the second positioning connecting rod 3010 and the first positioning connecting rod 305. Limiting plates 402 are provided on both sides of the outer ends of the outer connecting brackets 401, and bushings 403 are provided on the inner sides of the limiting plates 402. Gear rings 404 with an annular groove structure are provided on the outer sides of the bushings 403. A limiting guide wheel 405 is provided on the annular groove. The outer end of the limiting guide wheel 405 is provided with a connecting plate 406 whose output end is connected to the second electric gear 407. A track bar 408 is provided on one set of outer sides of the connecting plate 406, and a receiving block 409 is provided on the other set of outer sides of the connecting plate 406. The through groove structure of the receiving block 409 is engaged with the protrusion structure of the track bar 408. The track bar 408 is slidably connected to a sliding sleeve 4010 whose output end is connected to the electric guide wheel 4011. A pneumatic push rod 4012 is provided on the inner end of the sliding sleeve 4010. An electric rotating seat 4013 is provided on the inner side of the inner end of the pneumatic push rod 4012. A rotating arm 4014 is provided on the output end of the electric rotating seat 4013. An electric clamp 4015 is provided on the inner side of one end of the rotating arm 4014.

[0016] The limiting guide wheel 405 and the connecting plate 406 are arranged in a ring array around the central axis of the toothed ring 404. The track bar 408 has a straight-through structure, and the groove structure of the track bar 408 rolls and fits against the electric guide wheel 4011.

[0017] In this embodiment, when the impeller needs to be processed and installed, according to the distribution angle and density of the impeller, a corresponding number of limiting guide wheels 405, connecting plates 406, and second electric gears 407 are placed on the outer side of the gear ring 404. After the output of the second electric gear 407, the connecting plates 406 move to a suitable installation position on the gear ring 404. Through the specific structure of the impeller, the output of the electric guide wheel 4011 causes the sliding sleeve 4010 to move to a suitable position. Then, the extension and retraction of the pneumatic push rod 4012 and the rotation formed by the output of the electric rotating seat 4013 are used to adjust the angle of the rotating arm 4014. After the output of the electric clamp 4015 at one end of the rotating arm 4014, the impeller is clamped and positioned for subsequent processing and installation.

[0018] The rotating component 1 includes a machining table 101, a mounting base 102, an assembly plate 103, a rotating column 104, a driven gear 105, and a first electric gear 106. The machining table 101 is mounted on the machine tool via two sets of mounting bases 102. The driven gear 105, which is connected to the output end of the driven gear 105, is bolted to the inner side of the middle part of the machining table 101 via the assembly plate 103. The driven gear 105 is driven to run by meshing with the output end of the first electric gear 106.

[0019] In this embodiment, the processing table 101 is securely mounted on the machine tool by two sets of mounting bases 102 to ensure the stability of the entire device. When the first electric gear 106 outputs power to rotate, it drives the driven gear 105 and the rotating column 104 to rotate synchronously, thereby realizing the timely horizontal rotation of the pitch adjustment mechanism 2.

[0020] The pitch adjustment mechanism 2 includes a lower base groove 201, a first lead screw 202, a first slider 203, a hinge base 204, and a hinge rod 205. The top of the rotating column 104 is provided with a lower base groove 201, and the two chambers of the lower base groove 201 are provided with a first lead screw 202 whose output end is threadedly connected to the first slider 203. The hinge base 204, which is hinged to the hinge rod 205, is provided above the outer end of the first slider 203.

[0021] In this embodiment, after the output end of the lower base groove 201 is operated, the output end of the first lead screw 202 is rotated, driving the first slider 203 to move along the lead screw axis. The first slider 203 is connected to the hinge rod 205 through the hinge base 204, thereby driving the upper positioning rotation mechanism 3 and the blade clamping mechanism 4 to adjust the pitch angle.

[0022] The positioning and rotating mechanism 3 includes an upper base groove 301, a pad plate 302, a fixed base plate 303, a rotary motor 304, and a first positioning connecting rod 305. The upper base groove 301 with a cuboid cavity is hinged to the upper end of the hinge rod 205. The fixed base plate 303 is fixedly connected to one end of the upper base groove 301 through the pad plate 302. The first positioning connecting rod 305, which connects to the output end of the rotary motor 304, is provided on the upper inner side of the fixed base plate 303.

[0023] In this embodiment, when overall rotation is required, the rotary motor 304 on the fixed base plate 303 is used to rotate the overall product to a suitable processing angle for installation.

[0024] The positioning and rotating mechanism 3 also includes a second lead screw 306, a second slider 307, a connecting frame 308, a movable base plate 309, and a second positioning rod 3010. The second lead screw 306, whose output end is threadedly connected to the second slider 307, is provided in the cavity of the upper base groove 301. The outer end of the second slider 307 is fixedly connected to the movable base plate 309 on which the second positioning rod 3010 is installed through the connecting frame 308, and the central axis of the second positioning rod 3010 is on the same straight line as the central axis of the first positioning rod 305.

[0025] In this embodiment, after the output end of the upper base groove 301 is used to run, the output end of the second lead screw 306 is rotated, which can drive the second slider 307 and the moving base plate 309 to move along the axial direction of the second lead screw 306. This shortens the distance between the moving base plate 309 and the fixed base plate 303, allowing the second positioning rod 3010 and the first positioning rod 305 to position the center part of the impeller, and allowing the insertion block 409 to be inserted and engaged with the track bar 408.

[0026] The working principle of this guide vane milling clamping device is as follows: the machining table 101 is securely mounted on the machine tool through two sets of mounting seats 102 to ensure the stability of the entire device. When the first electric gear 106 outputs power to rotate, it drives the driven gear 105 and the rotating column 104 to rotate synchronously, thereby realizing the timely horizontal rotation of the pitch adjustment mechanism 2. After outputting the running through the output end of the lower base groove 201, the output end of the first lead screw 202 rotates, driving the first slider 203 to move along the lead screw axis. 03 is connected to the hinge rod 205 via the hinge base 204, thereby driving the upper positioning rotation mechanism 3 and blade clamping mechanism 4 to adjust the pitch angle. After outputting through the output end of the upper base groove 301, the output end of the second lead screw 306 rotates, which can drive the second slider 307 and the moving plate 309 to move along the axial direction of the second lead screw 306, so that the distance between the moving plate 309 and the fixed plate 303 is shortened, and the second positioning rod 3010 and the first positioning rod 305 hold the center of the impeller. Positioning is performed to allow the insertion block 409 to engage with the track bar 408. When impeller processing and installation are required, a corresponding number of limiting guide wheels 405, connecting plates 406, and second electric gears 407 are placed on the outer side of the gear ring 404 according to the impeller's distribution angle and density. The output of the second electric gear 407 causes the connecting plate 406 to move to the appropriate installation position on the gear ring 404. The specific structure of the impeller allows the output of the electric guide wheel 4011 to move the sliding sleeve 40... 10. Once the device has moved to a suitable position, the pneumatic push rod 4012 is extended and retracted, and the electric rotary seat 4013 is operated to rotate the device. The angle of the rotating arm 4014 is adjusted so that the electric clamp 4015 at one end of the rotating arm 4014 clamps and positions the impeller after the output operation, so as to facilitate subsequent processing and installation. When overall rotation is required, the rotary motor 304 on the fixed base plate 303 is used to rotate the entire product to a suitable processing angle for installation.
