Detailed implementation manner

[0029] To make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figures 1-5 , a welding quality detection mechanism, including a workbench 1, and a bending plate 2 fixedly connected to the top of the workbench 1, an electric push rod 3 slidably connected to the top of the bending plate 2, an ultrasonic welding quality detector 4 installed at the bottom of the electric push rod 3, and a driving member 5 installed on the outer wall of the bending plate 2. A rotating assembly 6 is arranged on the top of the workbench 1. The rotating assembly 6 is composed of a driving unit and a clamping unit. The driving unit is located on the top of the workbench 1, and the clamping unit is located above the workbench 1. A support assembly 7 is arranged on the top of the workbench 1.

[0031] The driving unit includes a driving motor 601, a driving shaft 602, a first gear 603, a swivel ring 604 and a tooth groove 605. The driving motor 601 is fixedly connected to the top of the workbench 1. The driving motor 601 is a double-shaft motor. The driving shaft 602 is arranged above the workbench 1. The driving shaft 602 is located at the output end of the driving motor 601. The first gear 603 is fixedly connected to one end of the driving shaft 602. The swivel ring 604 is arranged above the workbench 1. The tooth groove 605 is opened inside the swivel ring 604. The first gear 603 meshes with the tooth groove 605. After the driving motor 601 is started, the first gear 603 can be driven to rotate by the driving shaft 602. When the first gear 603 rotates, the swivel ring 604 can be driven to rotate.

[0032] The clamping unit includes a toothed ring 606, an outer ring 607, a support member 608, a sleeve 609, a second gear 610, a threaded rod 611, and a clamping member 612. The toothed ring 606 is fixedly connected to the outer wall of the rotating ring 604. The outer ring 607 is disposed outside the rotating ring 604. The support member 608 is fixedly connected to the outer wall of the outer ring 607. The sleeve 609 is installed on the outer wall of the support member 608. The sleeve 609 penetrates through the support member 608 and extends to the outside of the support member 608. The outer wall of the sleeve 609 is rotatably connected to the inner wall of the support member 608 that is penetrated. The sleeve 609 can rotate inside the support member 608. The second gear 610 is fixedly connected to one end of the sleeve 609. The second gear 610 meshes with the toothed ring 606. When the toothed ring 606 rotates, the sleeve 609 can be driven to rotate through the second gear 610. The threaded rod 611 is installed at one end of the sleeve 609. One end of the threaded rod 611 penetrates through the sleeve 609 and extends to the outside of the second gear 610. The outer wall of the threaded rod 611 is adapted to the inner wall of the sleeve 609 that is penetrated. The clamping member 612 is fixedly connected to one end of the threaded rod 611. A bent rod is fixedly connected to the outer wall of the clamping member 612. The bent rod located on the outer wall of the clamping member 612 penetrates through the support member 608 and is slidably connected to the inner wall of the support member 608. When the sleeve 609 rotates under the action of the second gear 610, the threaded rod 611 will push the clamping member 612 under the action of the thread and the bent rod to clamp and fix the tank body.

[0033] By providing the toothed ring 606 and the clamping member 612, the driving motor 601 drives the toothed ring 606 to rotate through the rotating ring 604. The toothed ring 606 drives the second gear 610 to rotate. Since the threaded rod 611 is adapted to the inner wall of the sleeve 609 fixed on the top of the second gear 610, when the second gear 610 rotates, the threaded rod 611 will push the clamping member 612 to move under the action of the thread and clamp and position the tank body. After the tank body is clamped, when the toothed ring 606 rotates, the tank body will be driven to rotate through the second gear 610 and the threaded rod 611, which facilitates the operator to detect the welded joint of the tank body through the ultrasonic welding quality detector 4; it solves the problem that the existing ultrasonic welding quality detection device cannot detect the quality of the circumferential weld.

[0034] The support component 7 includes a support frame 701, a rotating wheel 702, a fixing plate 703, and a clamping ring 704. The support frame 701 is fixedly connected to the top of the workbench 1. The rotating wheel 702 is rotatably connected to the inside of the support frame 701. The rotating wheel 702 contacts the outer wall of the rotating ring 604. The presence of the rotating wheel 702 can support the rotating ring 604. The fixing plate 703 is fixedly connected to the top of the workbench 1. The clamping ring 704 is arranged on the outer wall of the outer ring 607. The outer wall of the clamping ring 704 is rotatably connected to the outer wall of the outer ring 607. The bottom of the clamping ring 704 is fixedly connected to the top of the fixing plate 703. The clamping ring 704 can support the outer ring 607 without affecting the rotation of the outer ring 607.

[0035] By providing the rotating wheel 702 and the clamping ring 704, since the outer wall of the rotating ring 604 contacts the outer wall of the rotating wheel 702, the presence of the rotating wheel 702 can ensure the stability of the rotating ring 604 during rotation. At the same time, the presence of the clamping ring 704 can support the outer ring 607 without affecting the rotation of the outer ring 607 inside the clamping ring 704.

[0036] The working principle of this welding quality detection mechanism: Place the welded tank body on the outer wall of the clamping member 612, and control the driving motor 601 to rotate. The driving motor 601 drives the first gear 603 to rotate through the driving shaft 602. At this time, the first gear 603 drives the rotating ring 604 to rotate through the tooth groove 605, and the toothed ring 606 rotates under the action of the rotating ring 604. When the toothed ring 606 rotates, it drives the second gear 610 to rotate, so that the threaded rod 611 pushes the clamping member 612 to move under the action of the thread, so that the clamping member 612 located on the outer wall of the outer ring 607 completes the clamping of the tank body. After the clamping of the tank body is completed, the rotating ring 604 will drive the outer ring 607 to rotate through the toothed ring 606, the second gear 610, and the threaded rod 611, so that the tank body rotates under the action of the clamping member 612. Then, control the ultrasonic welding quality detector 4 to operate, and detect the welding quality of the welded part of the tank body through the ultrasonic welding quality detector 4.

[0037] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
