[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 of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.
[0024] Reference Figures 1-4 An adjustable tooling fixture for impeller machining includes a support frame 1. A fixing ring 2 is welded to the top of the support frame 1. An annular groove 7 is formed on the inner circumference of the fixing ring 2. A limit ring 8 is rotatably connected inside the annular groove 7. A turntable 3 for placing the impeller is provided inside the fixing ring 2, and the turntable 3 is fixed to the limit ring 8. Multiple sliding openings 4 are formed on the upper surface of the turntable 3, and sliders 6 are slidably connected inside the sliding openings 4. A fixing rod 18 for clamping multiple impellers is welded to the top of the slider 6. The top of the slider 6 is provided with a mechanism for moving the impeller up and down. The limiting extrusion assembly has a power component at the bottom of the turntable 3 that drives the slider 6 to move along the slide 4. In use, the impeller is placed on the turntable 3, and then the impeller is clamped and fixed from the four corners by the fixing rod 18 on the slider 6. During the processing of the impeller, the turntable 3 can be rotated in the annular groove 7 through the limiting ring 8. The turntable 3 will drive the clamped impeller to rotate, so that the impeller can be operated at different positions without the need for the operator to move around, which improves the convenience of using the tooling fixture.
[0025] In this utility model, the power assembly includes an electric push rod 9, which is fixed to the bottom of the turntable 3 by bolts. One end of the telescopic part of the electric push rod 9 is fixed to a connecting block 10 by bolts. Multiple sides of the connecting block 10 are welded with first fixing seats 11. A connecting rod 12 is rotatably connected inside the first fixing seat 11. One end of the connecting rod 12 is rotatably connected to a second fixing seat 13, and the second fixing seat 13 is fixed to the slider 6. When the electric push rod 9 is activated to extend, the electric push rod 9 will push the connecting block 10 to move downward. The connecting block 10 will drive the first fixing seat 11 to move downward. The first fixing seat 11 will drive the slider 6 to move within the sliding opening 4 through the connecting rod 12 and the second fixing seat 13. The slider 6 will drive the fixing rod 18 to move, thereby clamping and fixing the impeller from the four corners of the impeller.
[0026] The extrusion assembly includes a U-shaped frame 14, which is welded to the top of the slider 6. Slide grooves 15 are formed on the inner walls of both sides of the U-shaped frame 14 at the top position. A slide plate 16 is slidably connected within the slide grooves 15. A stepped plate 17 is welded to the bottom of the slide plate 16. The top of the U-shaped frame 14 has an insertion assembly for fixing the stepped plate 17 after movement. The insertion assembly includes a pin 21. A sliding hole is formed on the top of the U-shaped frame 14, and the pin 21 is slidably connected within the sliding hole. A slot 22 is formed on the top of the slide plate 16, and the pin 21 can be inserted into the slot 22. Protrusions are integrally formed on both sides of the top of the slide plate 16. Two round rods 19 are welded between the two protrusions and pass through the U-shaped frame 14. Springs 20 are sleeved on the outer sides of the round rods 19, and the two ends of the springs 20 are fixed to the U-shaped frame 14 and the slide plate 16, respectively. Pulling the slide plate 16 to move within the slide grooves 15 causes the slide plate 16 to move, thus impacting the springs 20. When the slide plate 16 moves to the slot 22 and aligns with the pin 21, the pin 21 will move downward under the action of gravity and insert into the slot 22 to fix the slide plate 16. Then the impeller can be placed on the turntable 3. After the impeller is clamped and fixed, the pin 21 is pulled upward to disengage the pin 21 from the slot 22. At this time, the slide plate 16 will be reset under the action of the spring 20, so that the stepped plate 17 on the slide plate 16 will press the impeller, thereby limiting the impeller's vertical movement and making the impeller more stable. The top and bottom of the limiting ring 8 are provided with multiple spherical grooves 23, and multiple spherical grooves 23 are connected with rolling balls 24. During the rotation of the limiting ring 8, the balls 24 will rotate through friction, thereby reducing the friction of the limiting ring 8 rotation, facilitating the rotation of the turntable 3, and improving the use effect of the tooling fixture. The guide rod 5 is fixed in the slide 4 by bolts, and the guide rod 5 passes through the slider 6.
[0027] Working principle: During use, the slide plate 16 is pulled to move within the slide groove 15. During this movement, the slide plate 16 compresses the spring 20. When the slide plate 16 moves to the slot 22 and aligns with the pin 21, the pin 21 moves downwards under gravity and inserts into the slot 22 to fix the slide plate 16. Then, the impeller is placed on the turntable 3, and the electric push rod 9 is extended. The electric push rod 9 pushes the connecting block 10 downwards, which in turn moves the first fixed seat 11 downwards. The first fixed seat 11, through the connecting rod 12 and the second fixed seat 13, moves the slider 6 within the slide opening 4. The slider 6 then moves the fixing rod 18 into the slide opening 4. The movement of the rods allows the fixing rods 18 to clamp and fix the impeller at its four corners. Then, the pins 21 are pulled upwards to disengage from the slots 22. At this time, the slide plate 16 will reset under the action of the spring 20, thereby pressing the impeller with the stepped plate 17 on the slide plate 16, thus limiting the impeller's vertical movement and making the impeller more stable. During the impeller processing, the turntable 3 can rotate in the annular groove 7 through the limiting ring 8. The turntable 3 will drive the clamped impeller to rotate, allowing operation on different positions of the impeller without the need for workers to move around, thus improving the convenience of using the tooling fixture.
[0028] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
