Detailed Embodiments

[0017] The present utility model will be specifically described below with reference to the drawings.

[0018] Embodiment: A welding and fixing fixture for a stirring paddle, as Figures 1 - 3As shown in the figure, it includes a bottom plate 1, a rotating shaft 2, a stepped turntable 3, a limiting rod 301, a U-shaped frame 4, a fixed seat 5, a sliding seat 6, an annular gear disc 8 and a fixing component. A rotating shaft 2 is fixedly connected to the bottom plate 1. The top of the rotating shaft 2 is rotatably connected to a stepped turntable 3. The stepped turntable 3 has at least three layers. The top layer of the stepped turntable 3 is a top column, on which a limiting rod 301 is slidably connected. The limiting rod 301 is used to fix the shaft sleeve 11. Four U-shaped frames 4 are fixedly connected to the bottommost layer of the stepped turntable 3. Fixed seats 5 are slidably connected to the upper parts of the U-shaped frames 4. Sliding seats 6 are slidably connected inside the U-shaped frames 4. Oblique sliding grooves are provided on the top surface of the sliding seat 6 and the bottom surface of the fixed seat 5, and the two are engaged through the oblique sliding grooves. When the sliding seat 6 moves, the sliding seat 6 can drive the fixed seat 5 to slide on the upper part of the U-shaped frame 4 through the oblique sliding grooves, so that the fixed seat 5 approaches or moves away from the shaft sleeve 11. An annular gear disc 8 is rotatably connected to the second layer of the stepped turntable 3 from bottom to top. Rack teeth are provided on one side of the sliding seat 6 close to the annular gear disc 8. The sliding seats 6 are all engaged with the annular gear disc 8 through their rack teeth. When one of the sliding seats 6 moves, it will drive the annular gear disc 8 to rotate through the rack teeth, and the annular gear disc 8 will drive the remaining sliding seats 6 to move through the rack teeth. A fixing component for fixing the paddle 10 is provided on the fixed seat 5.

[0019] As Figure 3 shown, the fixing component includes a bidirectional lead screw 901 and clamping plates 902. Bidirectional lead screws 901 are rotatably connected to the upper parts of the fixed seats 5. Two clamping plates 902 are slidably connected to the upper parts of the fixed seats 5. The two clamping plates 902 are both threadedly connected to the adjacent bidirectional lead screws 901. When the bidirectional lead screws 901 rotate, the two clamping plates 902 will slide along the bidirectional lead screws 901 in the direction of approaching or moving away from each other, so as to clamp or loosen the paddle placed between the two clamping plates 902.

[0020] As Figure 3 shown, it further includes a screw rod 701 and a fixed rod 702. A screw rod 701 is rotatably connected inside one of the U-shaped frames 4, and fixed rods 702 are fixedly connected inside the remaining U-shaped frames 4. One of the sliding seats 6 is threadedly connected to the screw rod 701, and the remaining sliding seats 6 are all slidably connected to the fixed rods 702. When the screw rod 701 rotates, it can drive the sliding seat 6 connected to it to move inside the U-shaped frame 4. When the sliding seat 6 connected to the fixed rod 702 moves under the drive of the annular gear disc 8, the fixed rod 702 can guide the sliding seat 6 connected to it.

[0021] The stirring paddle to be welded consists of a bushing 11 and blades 10. During use, the bushing 11 is sleeved downward onto the top post of the stepped turntable 3, and the bushing 11 is fixed by the limiting rod 301. Then, the four blades 10 are respectively placed between the two clamping plates 902 of each fixing seat 5. By rotating all the bidirectional lead screws 901, the corresponding two clamping plates 902 move closer to each other, so that each pair of clamping plates 902 fixes one blade 10, realizing the fixation of all the blades 10. Then, by rotating the screw rod 701, the slide block 6 connected thereto is driven to move within the U-shaped frame 4. Since the inclined chute on the top surface of the slide block 6 meshes with the inclined chute on the bottom surface of the fixing seat 5, and the inclined chute has a guiding function, the movement of the slide block 6 drives the fixing seat 5 to slide towards the bushing 11. At the same time, since a rack is provided on one side of the slide block 6 close to the annular gear disk 8, and the rack meshes with the annular gear disk 8, the sliding of the slide block 6 drives the annular gear disk 8 to rotate. Thus, the annular gear disk 8 drives the other slide blocks 6 to slide along the corresponding fixing rods 702, and further the other slide blocks 6 drive the corresponding fixing seats 5 to slide towards the bushing 11, so that the blades 10 on the four fixing seats 5 all move towards the bushing 11 until the blades 10 are all in close contact with the bushing 11. Since the inclined chute also has a certain self-locking function, the fixing seat 5 will be locked in the current position, which helps the blade 10 to maintain a stable contact with the bushing 11 during the welding process, thereby improving the welding quality. Then, the worker welds one of the blades 10 onto the bushing 11, and then by rotating the stepped turntable 3, the contact surface of another blade 10 with the bushing 11 is turned towards the worker's side, and this is repeated until all the blades 10 are welded onto the bushing 11.

[0022] As Figure 2 shown, it further includes a turning handle 302. The turning handle 302 is welded to the bottom of the stepped turntable 3. The turning handle 302 provides a part that is convenient to grip and apply force. The worker can easily drive the rotation of the stepped turntable 3 by rotating the turning handle 302, saving the worker's physical strength.

[0023] As Figure 2 shown, it further includes an anti-slip pad 101. At least one anti-slip pad 101 is fixedly connected to the bottom of the bottom plate 1. The anti-slip pad 101 can increase the friction between the bottom plate 1 and the ground, prevent the fixture from moving or sliding due to external forces during the welding process, and improve the stability of the fixture during the welding operation.

All equivalent structural or equivalent process transformations made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present invention.
