Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pot manufacturing and processing, specifically to a pot inner expansion clamping tool. BACKGROUND

[0002] In the production and processing of pots, it is often necessary to clamp and fix the pots to facilitate subsequent processing operations. Traditional clamping methods mostly use mechanical clamping, but stainless steel pots have thin walls, with a wall thickness of generally between 0.8-4 mm. Improper clamping during actual polishing can cause flying material or deformation of the pot, thereby resulting in low processing quality and affecting the yield. Therefore, developing a new type of pot clamping tool that has good clamping effect and does not damage the surface of the pot has become a problem that needs to be solved by those skilled in the art. SUMMARY

[0003] In order to overcome the problems in the prior art, the purpose of the utility model is to provide a pot inner expansion clamping tool.

[0005] Main working principle: the tool mainly includes a clamping seat, a connecting plate, and a transition flange. The clamping seat is cylindrical, with an opening at one end. The connecting plate is buckled at the opening of the clamping seat and is fixedly connected with the disc surface of the transition flange. The clamping seat, the connecting plate, and the transition flange are arranged in concentric circles to form a whole clamping structure.

This clamping method uses the expandability of the air bag to achieve flexible clamping of the pot. In actual operation, first, place the pot in the clamping seat to ensure that the center of the pot is aligned with the center of the clamping seat. Then, air is supplied to the air bag through the external pipeline, and the air bag starts to expand, gradually increasing the clamping force on the pot. When the air bag expands to a certain extent and can reliably fix the pot, stop the air supply and complete the clamping process.

[0013] Compared with the prior art, the utility model has the beneficial effects that:

[0014] The utility model discloses a pot inner expansion clamping tool, which comprises a clamping seat, a plurality of air bags arranged in the clamping seat, a plurality of limiting grooves arranged in the clamping seat and a connecting plate connected with the clamping seat.

[0015] In addition, by controlling the air pressure of the external pipeline, the expansion and contraction of the air bag can be quickly realized, so that the pot can be quickly clamped and loosened, the convenience and efficiency of production operation are improved, the stability of clamping and the machining precision are improved, the defective rate in the machining process is reduced, the product quality is improved, and the production cost is reduced.

[0020] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of this application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present invention. The embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0022] Example 1

[0023] This embodiment discloses a cookware internal expansion clamping tool, such as Figs. 1-2 As shown, it includes a clamping base 1, a transition flange 3, a connecting plate 2, and an air bag 4. The clamping base 1 adopts a cylindrical design with an opening at one end to facilitate the placement and removal of pots and pans. At the same time, reinforcing ribs can be provided inside the clamping base 1 as needed to enhance its structural strength. An air bag 4 is provided on the inner wall of the clamping base 1, and the air bag 4 is connected to the external pipeline. The connecting plate 2 is designed in a disc shape and is used to be fixedly connected to the clamping base 1. The disk surface of the transition flange 3 is fixedly connected to the connecting plate 2 to ensure that the clamping base 1, the connecting plate 2 and the transition flange 3 are arranged concentrically. The transition flange 3 can be designed to connect other equipment as needed.

[0024] When the pot needs to be clamped, the air bag 4 is inflated by the external pipeline, and the air bag 4 is inflated. The inflated air bag 4 is tightly pressed inward, thereby fixing the pot. This clamping method utilizes the expandability of the air bag 4 to achieve flexible clamping of the pot. In actual operation, first, the pot is placed on the clamping seat 1, and the center of the pot is aligned with the center of the clamping seat 1. Then, the air bag 4 is inflated by the external pipeline, and the air bag 4 begins to inflate, gradually increasing the clamping force on the pot. When the air bag 4 inflates to a certain extent and can reliably fix the pot, the inflation is stopped, and the clamping process is completed.

[0025] In some optional embodiments, in order to avoid the air bag 4 from shifting during operation, a limiting groove 10 is provided on the inner wall of the clamping seat 1, and the air bag 4 is sleeved in the limiting groove 10, thereby limiting the position of the air bag 4.

[0026] In some optional embodiments, the number of air bags 4 is at least two, each air bag 4 is sleeved in the limiting groove 10 on the periphery of the clamping seat 1, and there is a gap between each air bag 4. By clamping the pot with multiple air bags 4, the overall stress is more uniform, and damage to the pot caused by excessive stress on a single air bag 4 can be avoided. At the same time, the material of the air bag 4 should have sufficient elasticity and wear resistance to ensure its service life and clamping effect.

[0027] In some optional embodiments, the manifold 5 is provided on the outside of the clamping seat 1, the gas inlet of the manifold 5 is connected with the external pipeline, and the gas outlet is connected with the air bag 4 on the inner wall through the through hole in the side wall of the clamping seat 1. The design of the manifold 5 should ensure that the air pressure between the air bags 4 is evenly distributed.

[0028] In some optional embodiments, the center of the connecting plate 2 is provided with a suction cup 6, and the suction cup 6 is connected with the external pipeline. The design of the suction cup 6 ensures that it can be firmly attached to the pot from the outside during clamping, thereby enhancing the stability of clamping. At the same time, the position of the suction cup 6 is limited to the center, thereby more stably adsorbing the pot.

[0029] In some optional embodiments, a handle is provided on the outside of the clamping seat 1, and the manifold 5 is located in the handle. The gas outlet of the manifold 5 is connected with the air bag 4, and the gas inlet of the manifold 5 extends from one side of the handle and is connected with the external pipeline. This setting not only ensures that the manifold 5 can be smoothly connected with the air bag 4, but also provides a handle for holding, thereby making it more convenient to move the device.

[0030] In some optional embodiments, a recess 20 is provided on the periphery of the clamping seat 1, and the diameter of the recess 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 recess 20. A plurality of fixing holes are distributed along the circumference of the recess 20 at the edge of the connecting plate 2.

[0031] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any form. Any modification, equivalent change and modification of the above embodiments, which does not deviate from the technical solution of the present application and is based on the technical essence of the present application, still belongs to the scope of the technical solution of the present application.
