Description

Technical Field

[0001] This utility model belongs to the field of welding tooling technology, and in particular relates to a welding tooling for a paddle mixer blade. Background Technology

[0002] The blade welding fixture for paddle mixers is a welding device used to fix and position the blades and hub of a paddle mixer. It is mainly used to ensure welding accuracy and efficiency. The positioning device ensures the concentricity, symmetry and positional accuracy of the blades and hub, avoids manual calibration errors and improves welding efficiency and quality.

[0003] Currently, blades are typically fixed using components such as clamping plates and positioning rods. Since the blade shaft is circular, the shaft needs to be loosened and rotated to the back side for welding subsequent blades after welding one blade. This repeated fixing welding method is too cumbersome, wastes time, and results in low welding efficiency. In addition, different blades require clamping devices of corresponding shapes for fixing, but the current tooling clamping plate connection structure is complex and difficult to disassemble and assemble.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a welding fixture for the impeller of a paddle mixer, such as... Figure 1-4As shown, the fixture includes an operating table 1. The surface of the operating table 1 has three sets of grooves arranged in a circular array, each groove containing a sliding block 2. A positioning frame 3 is mounted on the top of each sliding block 2, located on the upper surface of the operating table 1. A first motor 4 is installed at the bottom of the operating table 1. The output of the first motor 4 is connected to a turntable 5. The surface of the turntable 5 has three sets of arc-shaped grooves arranged in a circular array, each groove containing a limiting block 6. The bottoms of the three sets of sliding blocks 2 are connected to the three sets of limiting blocks 6. A support column 7 is installed at the bottom of the operating table 1. A connecting column 8 is rotatably connected to the bottom of the support column 7, and the connecting column 8 is mounted above a base 9. A worm gear 10 is fitted onto the surface of the support column 7. A worm 11 is rotatably mounted on the side wall of the connecting column 8, meshing with the worm gear 10. A second motor 12 is installed on the side wall of the connecting column 8, and the output shaft of the second motor 12 is connected to the end of the worm 11. When this fixture is used, the blade shaft to be welded can be... The shaft is vertically positioned on the surface of the operating table 1. Then, the first motor 4 is started, which drives the turntable 5 to rotate. Since the slider 2 is connected to the limit block 6, the rotation of the turntable 5 will cause the three sets of limit blocks 6 to slide towards the center of the turntable 5. Under the action of the limit block 6, the slider 2 moves closer to the center of the operating table 1. At this time, the three sets of positioning frames 3 fix the shaft at the center of the operating table 1. By setting the three sets of positioning frames 3, the shaft can be positioned and fixed, so that the shaft is accurately placed at the center of the operating table 1. During the welding process of the shaft, the second motor 12 can be started. The second motor 12 drives the worm gear 11 to rotate, and the worm wheel 10 rotates under the action of the worm gear 11. The worm wheel 10 will drive the support column 7 to rotate, so that the operating table 1 can rotate as a whole. This setting makes it easy to weld the shaft in all directions without having to repeatedly fix the shaft to weld multiple blades, thereby improving the convenience of the welding work and thus improving the welding efficiency.

[0021] The upper end of the base 9 is equipped with a first electric cylinder 13, and the bottom of the connecting column 8 is installed on the top of the output shaft of the first electric cylinder 13. By setting the first electric cylinder 13, the first electric cylinder 13 can push the connecting column 8 to rise or fall. This setting can adjust the height of the operating table 1, so as to facilitate operation by workers of different heights and to facilitate welding of shafts of different lengths.

[0022] A bracket 14 is installed on the side wall of the operating table 1, and a balance arm 15 is installed on the top of the bracket 14. A clamping frame 16 is installed on the movable end of the balance arm 15. By setting the balance arm 15, the clamping frame 16 can clamp the blades of the blade propeller and place them stably through the balance arm 15, thereby improving the accuracy of the welding work and making the welding work more labor-saving.

[0023] The rear side wall of the clamping frame 16 has a groove, and one of the arms of the balance arm 15 has a groove. A connecting plate 17 is slidably installed in the groove. A spring 18 is connected to the upper end of the connecting plate 17, and the other end of the spring 18 is connected to the inner wall of the groove of the balance arm 15. A locking block 19 and a pressure rod 20 are respectively installed on the lower end of the connecting plate 17. The balance arm 15 is slidably inserted into the groove of the clamping frame 16, and the locking block 19 is locked into the inner side wall of the groove of the clamping frame 16. The balance arm 15 and the clamping frame 16 are slidably inserted and fixed by the cooperation of the spring 18, the connecting plate 17 and the locking block 19. The clamping frame 16 can be removed by pushing the pressure rod 20 to push the locking block 19 out of the slot of the clamping frame 16. This connection method makes it easy to quickly change the corresponding clamping frame 16 according to different sizes of blades.

[0024] The clamping frame 16 is C-shaped, and a second electric cylinder 21 is installed on the top of the clamping frame 16. The output of the second electric cylinder 21 extends to the inside of the clamping frame 16 and is connected to the clamping plate 22. By setting the second electric cylinder 21, the second electric cylinder 21 pushes the clamping plate 22 to achieve stable clamping of the blade.

[0025] The surface of the operating table 1 is set to be circular, and the lower side of the operating table 1 is set to be frustum-shaped. By setting the operating table 1 to be circular, there will be no corners that will hit the human body when it rotates.
