[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0022] The present invention relates to a tooling for welding the upper cover plate of the heating cavity body, such as... Figure 1-8 As shown, the fixture includes a base plate 1. Four rectangular support platforms 6 are arranged on the upper end of the base plate 1. Each support platform 6 has a pillar 10 at its upper center. Two diagonally opposite pillars 10 have a hole protrusion 11 at their upper ends. The four support platforms 6 form a rectangular space. A side-lifting device 2 is installed on the upper end of the base plate 1 at the front, back, left, and right sides of the rectangular space. Multiple clamping devices 3 are also installed around the upper end of the base plate 1 around the rectangular space. The side-lifting device 2 includes a base 12, a side-lifting cylinder 13, and a pusher block 14. The base 12 is fixed to the fixture. At the upper end of the base plate 1, a horizontally sliding push block 14 is installed in the upper part of the base 12. A side-top cylinder 13 is installed at the lower part of the base 12. A vertically arranged connecting rod 15 is installed at one end of the piston rod of the side-top cylinder 13. A groove 19 is opened on the outer side of the upper part of the connecting rod 15. A spring 17 and a movable pin 16 are installed in the groove 19. One end of the movable pin 16 passes through the spring 17 and the connecting rod 15 and connects to the push block 14. An insert 18 is embedded in the upper part of the free end of the push block 14. A mating groove 20 is opened between the free end of the insert 18 and the free end of the push block 14.

[0023] The tooling base plate 1 has a lifting ring 5 installed at one of the two diagonally opposite corners on its upper end. The lifting rings 5 ​​facilitate the hoisting of the entire tooling.

[0024] The tooling base plate 1 is equipped with multiple limiting posts 7 at the left middle and right rear corner of the rectangular space; the limiting posts 7 make it easy for the heating chamber body 4 to be accurately placed on the four support platforms 6.

[0025] The tooling base plate 1 has several fulcrum cylinders 8 installed on its upper end within a rectangular space. The fulcrum cylinders 8 are arranged vertically, and a fulcrum rod 9 is fixedly connected to the upper end of the piston rod of each fulcrum cylinder 8.

[0026] There are four clamping devices 3. The clamping devices 3 are clamping cylinders of the brand Airtac. These clamping cylinders are readily available on the market and are existing components, so their specific structure will not be described in detail. The clamping devices 3 can also be vertically arranged cylinders. A pressure plate is installed on the piston rod of the cylinder, and the pressure plate is controlled by the cylinder to clamp the product.

[0027] The upper part of the free end of the push block 14 is provided with a slot 21, and one end of the insert block 18 is inserted into the slot 21 and fixed with fasteners; the insert block 18 is designed to be replaceable for easy maintenance.

[0028] like Figure 8 As shown, the heating chamber body 4 is positioned along the side of the limiting post 7 and placed on the support columns 10 of the four support platforms 6. The four support columns 10 respectively support the mounting posts 23 at the four corners of the heating chamber body 4. The hole protrusions 11 at the upper end of the two diagonally opposite support columns 10 are inserted into the corresponding mounting holes to achieve initial positioning of the heating chamber body 4. Then, the four side-lifting devices 2 are activated. The four side-lifting cylinders 13 control the four push blocks 14 to move closer together through the connecting rod 15 until the four push blocks 14 respectively press against the sides of the heating chamber body 4. The upper part of the free end of the push block 14 is embedded with the mounting block 18. The mating groove 20 between the push block 14 and the mounting block 18 mates with the protruding part on the side of the heating chamber body 4 to ensure the stability of the side pressing. Then, the upper cover plate 22 is placed on the upper end of the heating chamber body 4. The upper cover plate 22 seals the upper port of the inner cavity. The four pressing devices 3 are activated to press the four corners of the upper cover plate 22 respectively to ensure that the relative position between the heating chamber body 4 and the upper cover plate 22 is not fixed. Then, the heating chamber body 4 and the upper cover plate 22 are welded by the welding equipment.

[0029] After welding is completed, the clamping device 3 and the side-lifting device 2 are reset and the clamping is released. The fulcrum cylinder 8 is then activated, and the fulcrum cylinder 8 controls the fulcrum rod 9 to move upward, pressing against the node 25 at the bottom of the heating chamber body 4 to lift the welded product. The bottom of the heating chamber body 4 has multiple nodes 25, and lifting the product through the nodes 25 positions can minimize product deformation.

[0030] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0031] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0032] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0033] The above provides a detailed description of a tooling for welding a cover plate to the main body of a heating chamber. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
