[0002] During the production and processing of cookware, it is often necessary to clamp and fix the cookware to facilitate subsequent processing operations. Traditional clamping methods mostly use mechanical clamping. However, the wall thickness of stainless steel cookware is thin, generally between 0.8 - 4 mm. Improper clamping during actual grinding will cause flying materials or deformation of the cookware, resulting in low processing quality and affecting the yield rate. Therefore, developing a new type of cookware clamping tooling with good clamping effect and no damage to the surface of the cookware has become a problem that needs to be solved by those skilled in the art. Content of the Utility Model

[0003] In order to overcome the problems existing in the prior art, the purpose of the utility model is to provide an external expansion clamping tooling for cookware.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an external expansion clamping tooling for cookware, including: a clamp base, a connecting plate, and a transition flange; the clamp base is in a cylindrical shape, and the opening of the cylindrical shape is provided at one end of the clamp base, the connecting plate is buckled at the opening of the clamp base, and the connecting plate is fixedly connected with the disk surface of the transition flange; an airbag for clamping the cookware is arranged outside the clamp base, and the airbag is connected with an external pipeline; when it is necessary to clamp the cookware, the external pipeline is ventilated to cause the airbag to expand and tightly fix the cookware; the clamp base, the connecting plate, and the transition flange are concentrically arranged.

[0005] Main working principle: This tooling mainly includes three parts: a clamp base, a connecting plate, and a transition flange. The clamp base is in a cylindrical shape with an opening at one end. The connecting plate is buckled at the opening of the clamp base and is fixedly connected with the disk surface of the transition flange. The clamp base, the connecting plate, and the transition flange are concentrically arranged to form an integral clamping structure. An airbag is arranged outside the clamp base, and the airbag is connected with an external pipeline. When it is necessary to clamp the cookware, air is introduced into the airbag through the external pipeline to make the airbag expand. The expanded airbag will tightly push outwards to fix the cookware. This clamping method utilizes the expandability of the airbag to achieve flexible clamping of the cookware. In actual operation, first place the cookware on the clamp base to ensure that the center of the cookware is aligned with the center of the clamp base. Then, introduce air into the airbag through the external pipeline, and the airbag starts to expand, gradually increasing the clamping force on the cookware. When the airbag expands to a certain extent and can reliably fix the cookware, the ventilation can be stopped to complete the clamping process.

[0006] Preferably, a limiting groove is arranged outside the clamp base, and the airbag is sleeved in the limiting groove.

[0007] Preferably, the number of the air bags is at least two, and the number of the limiting grooves corresponds to that of the air bags.

[0008] Preferably, through holes are formed in the side wall of the clamping seat, a manifold is arranged in the clamping seat, an air outlet of the manifold is connected with the air bag through the through hole, and an air inlet of the manifold is connected with an external pipeline.

[0009] Preferably, a suction cup is arranged at one end of the clamping seat away from the connecting plate, the suction cup is located at the center of the end of the clamping seat away from the connecting plate, and the suction cup is connected with an external pipeline.

[0010] Preferably, the clamping seat comprises an outer expansion fixture sleeve and a front end cover;

[0011] The front end cover is buckled at the bottom of the outer expansion fixture sleeve, the air bag is sleeved around the outer expansion fixture sleeve, and the suction cup is arranged on one side of the front end cover facing away from the outer expansion fixture sleeve.

[0012] Preferably, a groove is formed in the periphery of the connecting plate, and the clamping seat is connected by buckling through the groove.

[0013] Preferably, a groove is formed in the periphery of the connecting plate, and the clamping seat is connected by buckling through the groove.

[0014] Preferably, a plurality of fixing holes are distributed in a circumferential manner along the groove at the edge of the connecting plate, a plurality of screw holes are arranged at the opening edge of the clamping seat corresponding to the fixing holes, and the fixing holes and the screw holes are arranged opposite to each other and are fixedly connected by screws.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The utility model tightly fixes the cookware by the expansion of the air bag. Compared with the traditional mechanical clamping method, it can provide more uniform and stable clamping force, effectively preventing the cookware from moving or deforming during the processing. At the same time, the design of the air bag allows adjustment according to the size and shape of the cookware. By controlling the expansion degree of the air bag, it can adapt to cookware of different sizes and shapes, realizing flexible clamping. And as a clamping medium, the part of the air bag in direct contact with the cookware is made of soft material, which can effectively avoid the surface scratches or indentations on the cookware caused by the traditional clamping method, protecting the surface quality of the cookware.

[0017] In addition, by controlling the air pressure in the external pipeline, the inflation and contraction of the airbag can be quickly achieved, thereby quickly clamping and releasing the cookware, improving the convenience and efficiency of production operations. By improving the clamping stability and processing accuracy, the rejection rate during the processing can be reduced, the product quality can be improved, and thus the production cost can be reduced. At the same time, due to the optimization of the clamping method, the wear and maintenance costs of the equipment can also be reduced. In summary, the cookware external expansion clamping tooling provided by this claim has beneficial effects such as high clamping stability, strong adaptability, good surface protection, convenient operation, high safety, and reduction of production costs. These advantages make this tooling have a wide application prospect in the field of cookware processing. Brief Description of the Drawings

The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0024] Embodiment 1

[0025] This embodiment discloses an external expansion clamping tooling for cookware. As shown in Figure 1 - Figure 2 , it includes a clamping seat 1, a transition flange 3, a connecting plate 2, and an airbag 4. The clamping seat 1 is designed in a cylindrical shape with one end open for the insertion and removal of the cookware. Meanwhile, reinforcing ribs can be arranged inside the clamping seat 1 as needed to enhance its structural strength. An airbag 4 is provided around the clamping seat 1, and the airbag 4 is connected to an external pipeline. The connecting plate 2 is designed as a disc shape and is used for fixedly connecting with the clamping seat 1. The plate surface of the transition flange 3 is fixedly connected to the connecting plate 2 to ensure that the clamping seat 1, the connecting plate 2, and the transition flange 3 are concentrically arranged. The transition flange 3 can be designed to connect to other devices as needed.

[0026] When it is necessary to clamp the cookware, air is introduced into the airbag 4 through an external pipeline, causing the airbag 4 to expand. The expanded airbag 4 will tightly push outwards, thereby fixing the cookware. This clamping method utilizes the expandability of the airbag 4 to achieve flexible clamping of the cookware. In actual operation, first, place the cookware on the clamping seat 1 to ensure that the center of the cookware is aligned with the center of the clamping seat 1. Then, introduce air into the airbag 4 through an external pipeline, and the airbag 4 starts to expand, gradually increasing the clamping force on the cookware. When the airbag 4 expands to a certain extent and can reliably fix the cookware, the air supply can be stopped to complete the clamping process.

[0027] In some optional embodiments, in order to prevent the airbag 4 from shifting during operation, a limiting groove 10 is provided on the periphery of the clamping seat 1, and the airbag 4 is sleeved in the limiting groove 10 to limit the position of the airbag 4 in this way.

[0028] In some optional embodiments, the number of airbags 4 is at least two. Each airbag 4 is sleeved in the limiting groove 10 on the periphery of the clamping seat 1, and there is a gap between each airbag 4. The cookware is clamped by multiple airbags 4, making the overall force more uniform and avoiding damage to the cookware caused by excessive stress on a single airbag 4. At the same time, the material of the airbag 4 should have sufficient elasticity and wear resistance to ensure its service life and clamping effect.

[0029] In some optional embodiments, a manifold 5 is arranged inside the clamping seat 1. Its air inlet is connected to an external pipeline, and its air outlet is connected to the airbag 4 through a through hole on the side wall of the clamping seat 1. The design of the manifold 5 should ensure uniform air pressure distribution among the airbags 4.

[0030] In some optional embodiments, a suction cup 6 is located at the center of the end of the clamping seat 1 away from the connecting plate 2 and is connected to an external pipeline. The design of the suction cup 6 should ensure that it can firmly adsorb on the cookware during the clamping process to enhance the clamping stability. At the same time, the position of the suction cup 6 is limited to the center to more stably adsorb the cookware.

[0031] ​​In some alternative embodiments, the clamping seat 1 includes an externally expandable fixture sleeve 11 and a front end cover 12. The front end cover 12 is buckled to the bottom of the externally expandable fixture sleeve 11, and the suction cup 6 is arranged on the side of the front end cover 12 facing away from the externally expandable fixture sleeve 11. By arranging the suction cup 6 and the airbag 4 on different components respectively, the installation of the suction cup 6 and the airbag 4 is facilitated.

[0032] In some alternative embodiments, a groove 20 is provided on the periphery of the clamping seat 1, and the diameter of the groove 20 is slightly larger than the opening diameter of the clamping seat 1, so that the clamping seat 1 can be buckled and connected to the connecting plate 2 through the groove 20, and a plurality of fixing holes are distributed along the circumference of the groove 20 at the edge of the connecting plate 2.

[0033] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Therefore, any modifications, equivalent changes and decorations made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
