Description

Technical Field

[0001] The utility model relates to welding technology, in particular to a rotary clamping device. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that uses heat, high temperature, or high pressure to join metals or other thermoplastic materials, such as plastics. Modern welding uses a variety of energy sources, including gas flame, arc, laser, electron beam, friction, and ultrasonic. Besides being used in factories, welding can also be performed in a variety of environments, such as outdoors, underwater, and in space. Regardless of the location, welding can pose a risk to the operator, so appropriate protective measures must be taken when welding.

[0003] When welding a product, it needs to be clamped in place with an external jig, then used with a welding device to complete the welding process. Existing welding jigs cannot adjust the product's position or angle after clamping it. Furthermore, some products require welding on multiple sides of the product in sequence. Therefore, after welding one side, the product needs to be removed and then the angle adjusted before welding the next side. This not only complicates the welding process and affects the efficiency of the product's welding process, but also easily causes the center position of the product to shift during removal and re-clamping, thus affecting the quality of the weld. Therefore, further improvements to existing clamping devices are necessary. Utility Model Content

[0027] Please refer to Figures 1 to 3 As shown, it shows the specific structure of a preferred embodiment of the present utility model, which includes a mounting frame 10, a rotating base 20, a first driving mechanism 30, a clamping jaw 40 and a driving assembly 50.

[0028] The mounting bracket 10 is arranged outside and located beside the external welding device.

[0029] The rotating seat 20 can be rotatably arranged on the mounting frame 10; in this embodiment, the rotating seat 20 is provided with a carrier 21 that cooperates with the product, and the carrier 21 is provided with a positioning hole 201 that cooperates with the product. Through the arrangement of the carrier 21 and the positioning hole 201, when clamping the product, the product can be positioned first, and then clamped and fixed by the clamping claw 40, further ensuring the quality of welding.

[0030] The first driving mechanism 30 is provided on the mounting frame 10 and drives the rotating base 20 to rotate back and forth; in this embodiment, the first driving mechanism 30 is a servo motor, which is used to conveniently control the rotation angle of the rotating base 20 and the product on the rotating base 20.

[0031] The two clamping jaws 40 are arranged in pairs, each of which is mounted on the rotating base 20 and rotates back and forth with the rotating base 20. In this embodiment, the clamping jaws 40 are located in front of the rotating base 20. The two clamping jaws 40 are symmetrically arranged on either side of the carrier 21. The clamping jaws 40 include an integrally formed clamping portion 41 and a connecting portion 42. The connecting portion 42 engages with the output end of the drive assembly 50 and drives the clamping portions 41 of the two clamping jaws 40 to open and close via the drive assembly 50. A connecting rod 421 is provided on the connecting portion 42.

[0032] The drive assembly 50 is mounted on the mounting frame 10 and drives the clamping jaws 40 to open and close. In this embodiment, the drive assembly 50 is mounted on the mounting frame 10 and is located behind the rotating base 20. The first drive mechanism 30 and the drive assembly 50 are located on the same side of the rotating base 20. By disposing the clamping jaws 40, the drive assembly 50 and the clamping jaws 40 are located on different sides of the rotating base 20. This prevents interference between the drive assembly 50 and external welding equipment when located outside the rotating base 20, reduces the overall size, and requires less installation space. The driving assembly 50 includes a guide portion 51 and a second driving mechanism 52; the guide portion 51 can be movably arranged on the mounting frame 10 back and forth, and two obliquely extending guide grooves 501 are provided on the guide portion 51, and there is a certain angle between the two guide grooves 501; in this embodiment, the two guide grooves 501 extend back and forth, and the distance between the two guide grooves 501 at one end away from the second driving mechanism 52 is smaller than the distance between the two guide grooves 501 at one end close to the second driving mechanism 52, so that when the second driving mechanism 52 drives the guide portion 51 to move forward, the two clamping jaws 40 are driven to clamp through the guide grooves 501. In other embodiments, the guide grooves 501 can also be set along other directions as long as they can drive the clamping jaws 40 to open and close. The connecting rod 421 of each clamping jaw 40 extends into the corresponding guide slot 501 and moves back and forth along the guide slot 501. The output end of the second drive mechanism 52 is rotationally connected to the guide portion 51, driving the guide portion 51 back and forth, ensuring that the rotation of the clamping jaw 40 and the guide portion 51 and the movement of the guide portion 51 driven by the second drive mechanism 51 do not affect each other. The second drive mechanism 52 is a pneumatic cylinder.

[0033] The design focus of the utility model is that: the rotating seat can be rotatably arranged on the mounting frame; and the two clamping jaws can be opened and closed and arranged on the rotating seat and rotate back and forth with the rotating seat; the driving assembly is arranged on the mounting frame and drives the clamping jaws to open and close; the clamping jaws rotate back and forth with the rotating seat, so that during welding, the clamped product can be driven to rotate by the clamping jaws, so that the welding process on the other side of the product can be completed without removing the product, which not only makes the welding process more convenient, but also improves the welding effect; and there is no need to go through the process of removing and re-clamping, which avoids the deviation of the center position of the product and ensures the quality of welding.

[0034] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
