Description

Technical Field

[0001] This utility model relates to the technical field of water heater manufacturing equipment, and in particular to a positioning structure for processing and producing water heater inner tanks. Background Technology

[0002] In the processing and production of water heater inner tanks, positioning is a key step to ensure the accuracy of subsequent welding, grinding and other processes. Currently, the existing water heater inner tank positioning devices on the market have some shortcomings in use.

[0003] Some positioning devices adopt a fixed structure design, which cannot be flexibly adjusted according to the different specifications of water heater inner tanks. For inner tanks with different diameters and lengths, it is necessary to replace the corresponding positioning components, which not only increases production costs but also reduces production efficiency. In addition, some adjustable positioning devices have a more complicated adjustment method and are inconvenient to operate. Moreover, during the positioning process, the fixing effect on the water heater inner tank is not good, and slippage and displacement are prone to occur, affecting the processing accuracy.

[0004] Meanwhile, the existing positioning device often uses rigid contact with the inner liner, which can easily lead to scratches and deformation on the surface of the inner liner, affecting product quality.

[0005] Therefore, this utility model proposes a positioning structure for the processing and production of water heater inner tanks. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a positioning structure for the processing and production of water heater inner tanks.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a positioning structure for processing and producing the inner tank of a water heater, including a base frame assembly, the base frame assembly being composed of a base plate and a vertical plate, and further including that a mounting rod is provided on the side of the vertical plate near the base plate, two mounting rods are provided in total, and a lead screw is rotatably connected to the vertical plate between the two mounting rods;

[0008] The rotating assembly consists of a rotating seat located at the end of the mounting pole away from the upright plate. Both the upper and lower ends of the rotating seat are provided with rotating shafts. The lead screw is rotatably connected to the rotating seat. A lead screw sliding seat is threaded onto the lead screw. Both the upper and lower ends of the lead screw sliding seat are rotatably connected to the rotating shafts. A connecting seat is rotatably connected between two adjacent connecting arms.

[0009] Furthermore, the top of the connecting seat is provided with an inner liner expansion positioning component, which consists of a positioning plate and a rubber anti-slip pad, both of which are arc-shaped structures.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: In the inner tank expansion positioning component, the arc-shaped positioning plate and the rubber anti-slip pad are attached to the arc-shaped inner wall of the water heater inner tank, which increases the contact area and fit, enhances the positioning stability, and the rubber material can buffer the pressure to avoid deformation of the inner tank or scratches on the inner wall. The arc design is suitable for inner tanks with different curvatures, taking into account both the positioning firmness and the protection of the workpiece, which helps to ensure the processing accuracy and product quality.

[0011] Furthermore, the rubber anti-slip pad has fault-tolerant holes, which are distributed in an arc and the included angle between two adjacent fault-tolerant holes is equal. The rubber anti-slip pad also has anti-slip grooves.

[0012] The beneficial effects of adopting the above-mentioned further solutions are as follows: the fault-tolerant holes on the rubber anti-slip pad can enhance its own elasticity and deformation ability, better adapt to the slight unevenness of the inner wall of the inner liner, and improve the tightness of the fit; the arc-shaped distribution and equal angle design make the force more uniform, avoid excessive local compression, and the anti-slip groove increases the friction with the inner liner, effectively preventing slippage and displacement during processing, which not only ensures the stability of positioning, but also reduces damage to the inner liner and helps to improve the processing accuracy.

[0013] Furthermore, limit sleeves are provided on both sides of the lead screw sliding seat, and the limit sleeves are slidably connected to the mounting column.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the limiting sleeves on both sides of the lead screw sliding seat slide in cooperation with the mounting pole, which can accurately guide the movement of the sliding seat, prevent it from deviating or shaking under the drive of the lead screw, and ensure smooth sliding. This structure not only enhances the stability of the overall movement, but also reduces frictional wear between components, extends service life, and ensures the accuracy of the connecting arm and subsequent positioning components, thus improving positioning reliability.

[0015] Furthermore, a drive motor is installed on the side of the upright plate away from the mounting pole, and the output end of the drive motor is connected to a lead screw.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the drive motor on one side of the upright plate is connected to the lead screw, which can drive the lead screw to rotate automatically, replacing manual adjustment, improving the convenience and efficiency of operation. The motor drive can provide stable power, making the lead screw rotate more smoothly, ensuring that the subsequent sliding seat and positioning components move accurately and consistently, reducing manual operation errors, ensuring positioning accuracy, and reducing the intensity of manual labor, thus meeting the needs of automated production.

[0017] Furthermore, a support plate is provided between the base plate and the upright plate, and mounting holes are provided at the four corners of the base plate.

[0018] The beneficial effects of adopting the above-mentioned further solutions are: the support plate between the base plate and the upright plate can enhance the connection strength between the two, improve the overall structural rigidity, reduce deformation and shaking when subjected to force, and the mounting holes at the corners of the base plate can easily fix the device firmly on the worktable, avoiding overall displacement during processing. The combination of the two not only strengthens the structural stability, but also ensures a reliable foundation for positioning operations, helping to improve the accuracy and safety during processing.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, the rotating seat of the rotating component achieves flexible rotation through the rotating shaft, and in conjunction with the lead screw driving the sliding seat to move linearly, the connecting arms work together to form a compound motion. This structure transforms the linear motion of the lead screw into a multi-angle expansion and positioning action, which can adapt to different specifications of inner liner and improve positioning stability through multi-arm coordination. The design of each rotating pair reduces motion resistance, making the adjustment process smoother, enhancing the flexibility and adaptability of the positioning structure, and ensuring reliable operation under complex working conditions.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1-5 As shown, this utility model provides a technical solution: a positioning structure for processing and producing the inner tank of a water heater, including a base frame assembly 1, which is composed of a base plate 11 and a vertical plate 12. It also includes a mounting rod 122 on the side of the vertical plate 12 near the base plate 11. There are two mounting rods 122 in total, and a lead screw 123 is rotatably connected on the vertical plate 12 between the two mounting rods 122.

[0032] The rotating assembly 2 consists of a rotating seat 21 located at the end of the mounting rod 122 away from the upright plate 12. Both the upper and lower ends of the rotating seat 21 are equipped with rotating shafts 22. A lead screw 123 is rotatably connected to the rotating seat 21, and a lead screw sliding seat 23 is threaded onto the lead screw 123. Connecting arms 24 are rotatably connected to both the upper and lower ends of the lead screw sliding seat 23 and the rotating shafts 22. Connecting seats 25 are rotatably connected between adjacent connecting arms 24. The rotating seat 21 of the rotating assembly 2 rotates flexibly via the rotating shafts 22, coordinating with the lead screw 123 to drive the sliding seat to move linearly, causing the connecting arms 24 to move in tandem to form a compound motion. This structure transforms the linear motion of the lead screw 123 into a multi-angle expansion and positioning action, adapting to different specifications of inner liner and improving positioning stability through multi-arm coordination. The design of each rotating pair reduces motion resistance, making the adjustment process smoother, enhancing the flexibility and adaptability of the positioning structure, and ensuring reliable operation under complex working conditions.

[0033] The top of the connecting seat 25 is provided with an inner tank expansion positioning component 3, which consists of a positioning plate 31 and a rubber anti-slip pad 32. Both the positioning plate 31 and the rubber anti-slip pad 32 are arc-shaped structures. In the inner tank expansion positioning component 3, the arc-shaped positioning plate 31 and the rubber anti-slip pad 32 fit against the arc-shaped inner wall of the water heater inner tank, increasing the contact area and fit, enhancing positioning stability. The rubber material can buffer pressure and prevent the inner tank from being deformed by pressure or scratched on the inner wall. The arc design is suitable for inner tanks with different curvatures, taking into account both positioning firmness and protection of the workpiece, which helps to ensure processing accuracy and product quality.

[0034] The rubber anti-slip pad 32 has fault-tolerant holes 321, which are distributed in an arc and the included angle between two adjacent fault-tolerant holes 321 is equal. The rubber anti-slip pad 32 has anti-slip grooves 322. The fault-tolerant holes 321 on the rubber anti-slip pad 32 can enhance its own elasticity and deformation ability, better adapt to the slight unevenness of the inner wall of the inner liner, and improve the tightness of the fit. The arc-shaped distribution and equal included angle design make the force more even and avoid excessive local compression. The anti-slip grooves 322 increase the friction with the inner liner, effectively preventing slippage and displacement during processing, which not only ensures the stability of the positioning, but also reduces damage to the inner liner and helps to improve the processing accuracy.

[0035] Both sides of the lead screw sliding seat 23 are provided with limit sleeves 231. The limit sleeves 231 are slidably connected to the mounting rod 122. The limit sleeves 231 on both sides of the lead screw sliding seat 23 and the mounting rod 122 are slidably engaged, which can accurately guide the movement of the sliding seat and prevent it from deviating or shaking under the drive of the lead screw 123, thus ensuring smooth sliding. This structure not only enhances the stability of the overall movement, but also reduces frictional wear between components and extends service life. At the same time, it ensures the accuracy of the action of the connecting arm 24 and subsequent positioning components, and improves the reliability of positioning.

[0036] A drive motor 121 is provided on the side of the upright plate 12 away from the mounting pole 122. The output end of the drive motor 121 is connected to the lead screw 123. The drive motor 121 on one side of the upright plate 12 is connected to the lead screw 123, which can drive the lead screw 123 to rotate automatically, replacing manual adjustment, improving the convenience and efficiency of operation. The motor drive can provide stable power, making the lead screw 123 rotate more smoothly, ensuring that the subsequent sliding seat and positioning components move accurately and consistently, reducing manual operation errors, ensuring positioning accuracy, and reducing the intensity of manual labor, which is suitable for the needs of automated production.

[0037] A support plate 13 is provided between the base plate 11 and the upright plate 12. Mounting holes 14 are provided at the four corners of the base plate 11. The support plate 13 between the base plate 11 and the upright plate 12 can enhance the connection strength between the two, improve the overall structural rigidity, and reduce deformation and shaking under stress. The mounting holes 14 at the corners of the base plate 11 make it easy to fix the device firmly on the worktable and avoid overall displacement during processing. The combination of the two not only strengthens the structural stability but also ensures a reliable foundation for positioning operations, helping to improve the accuracy and safety of processing.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
