Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle parts manufacturing technology, and in particular to a power supply housing friction welding fixture with shape-matching limit and online inspection functions. Background Technology

[0002] Friction welding is a commonly used joining process in the manufacturing of new energy drive power supply housings, enabling a robust connection between the various components of the housing. However, precise positioning and stable clamping of the power supply housing are required during friction welding to ensure welding quality.

[0003] like Figure 8 As shown, the top of the new energy drive power supply housing 30 requires the welding of two end caps 31 via friction welding. A window 32 is provided on one side of the housing, and a connecting post 33 is located at the bottom of the window 32. Existing friction welding fixtures have several shortcomings: firstly, the positioning structure of the new energy drive power supply housing 30 is poorly designed, making it difficult to guarantee the positioning accuracy of the power supply housing, resulting in significant dimensional deviations after welding and affecting product quality; secondly, the clamping effect of the clamping device is poor, and the housing is prone to loosening during welding, which not only affects welding accuracy but may also pose safety hazards. Furthermore, most existing fixtures lack the function of checking the position of the connecting post 33, making it impossible to effectively inspect the installation position of the connecting post 33 before welding. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a friction welding fixture for power supply housing with contour limiting and online inspection functions. Through the cooperation of the contour limiting protrusion on the contour block, the bottom edge block and the high support platform, the new energy drive power supply housing is accurately positioned in multiple directions, which effectively improves the positioning accuracy of the housing and ensures the dimensional accuracy of the product after welding.

[0026] 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.

[0027] The present invention relates to a friction welding fixture for a power supply housing with contour-mimicking limiting and online inspection functions, such as... Figure 1-8 As shown, the device includes a base plate 1. Several modular blocks 11 are arranged in the middle of the upper end of the base plate 1. The modular blocks 11 are spliced ​​together to form a complete shaped block 3. Several clearance holes 12 are provided on the upper end of the shaped block 3. The clearance holes 12 match the protruding parts of the new energy drive power supply housing 30, which can provide good support and initial positioning for the housing. Several bottom edge blocks 8 are installed on the front, rear, and left sides of the shaped block 3 on the upper end of the base plate 1. The bottom edge blocks 8 are provided with contour limiting protrusions 29 on the upper end. The contour limiting protrusions 29 are adapted to the edge contour shape of the bottom of the power supply housing, which can further limit the movement of the housing in the horizontal direction and improve the positioning accuracy.

[0028] Two high-level support platforms 6 are arranged side-by-side on the right side of the shaping block 3 at the upper end of the base plate 1. The high-level support platforms 6 are used to support the higher parts of the power supply housing, so that the housing remains horizontal and stable during welding. A point inspection device 7 is installed between the two high-level support platforms 6 at the upper end of the base plate 1. The point inspection device 7 includes a support column 13, a spring 14, and an inspection pin 15. A through hole 19 is vertically opened in the middle of the support column 13. The spring 14 and the inspection pin 15 are installed sequentially from bottom to top inside the through hole 19. An inspection groove 16 is opened at the upper end of the inspection pin 15. A limiting groove 18 is provided in the middle of the side, and a limiting bolt 17 is screwed onto the side of the support column 13. One end of the limiting bolt 17 is inserted into the limiting groove 18. Multiple first clamping devices 5 are installed on the upper end of the base plate 1 on both the front and rear sides of the shaped block 3. A second clamping device 9 is installed on the upper end of the base plate 1 on the outer side of each high support platform 6. Multiple end cap pressing devices 4 are installed on the upper end of the base plate 1 on the left side of the shaped block 3. The first clamping devices 5, the second clamping devices 9 and the end cap pressing devices 4 press the power supply housing from different positions to ensure that the housing will not be displaced during the welding process.

[0029] A lifting ring 2 is installed at each of the two diagonally opposite corners of the upper end of the base plate 1, which facilitates the handling of the tooling.

[0030] The base plate 1 has several guide posts 10 arranged around the shape block 3 on its upper end. The guide posts 10 play a guiding role when placing the power supply housing, so that the housing can be placed quickly and accurately in the designated position.

[0031] The end cap pressing device 4 includes a first pressing cylinder 20, a first rotating seat 21, and a first pressure plate 23. The first pressing cylinder 20 is vertically mounted on the upper end of the base plate 1. The piston rod of the first pressing cylinder 20 is rotatably connected to one end of the first pressure plate 23. A copper pressure block 24 is installed on the lower part of the other end of the first pressure plate 23. The first rotating seat 21 is mounted on one side of the piston rod of the first pressing cylinder 20. A first pressure block 24 is rotatably mounted on each side of the first rotating seat 21. Connecting piece 22, two first connecting pieces 22 are rotatably connected to the two sides of the middle part of the first pressure plate 23 respectively; when the end cover pressing device 4 needs to be pressed, the first pressing cylinder 20 is activated, the piston rod of the first pressing cylinder 20 extends, causing one end of the first pressure plate 23 to be lifted, and using the lever principle, the copper pressing block 14 at the other end of the first pressure plate 23 is pressed downward; the copper pressing block 14 is replaceable, and the copper pressing block 24 is relatively soft, which can avoid damage to the end cover of the power supply housing during the pressing process.

[0032] The first pressing device 5 and the second pressing device 9 have the same structure, both including a second pressing cylinder 25, a second rotating seat 26, and a second pressure plate 28. The second pressing cylinder 25 is vertically installed on the upper end of the base plate 1. The piston rod of the second pressing cylinder 25 is rotatably connected to one end of the second pressure plate 28. The second rotating seat 26 is provided on one side of the piston rod of the second pressing cylinder 25. A second connecting piece 27 is rotatably installed on each side of the second rotating seat 26. The two second connecting pieces 27 are rotatably connected to the two sides of the middle part of the second pressure plate 28, respectively. When the first pressing device 5 or the second pressing device 9 needs to be pressed, the second pressing cylinder 25 is activated. The piston rod of the second pressing cylinder 25 extends, causing one end of the second pressure plate 28 to lift. Using the lever principle, the other end of the second pressure plate 28 is pressed downward to achieve pressing.

[0033] The vertical cross-section of the limiting groove 18 is inverted triangular. The lower end of the through hole 19 is sealed by the upper end face of the base plate 1. The support column 13 is connected and fixed to the base plate 1 by fasteners. The limiting bolt 17 is an internal hex bolt. The cooperation between the limiting groove 18 and the limiting bolt 17 can limit the movement range of the inspection pin 15 and prevent it from coming out of the through hole 19.

[0034] Guided by the guide post 10, the new energy drive power supply housing 30 to be welded is fitted onto the conformal block 3, so that the edge contour of the new energy drive power supply housing 30 fits with the contour limiting protrusion 29 on the bottom edge block 8. At the same time, the higher part of the right side of the new energy drive power supply housing 30 is placed on two high-position support platforms 6. At this time, the point inspection device 7 starts to work. If the corresponding position of the insertion post 33 at the housing window 32 is accurate, the insertion post 33 will be inserted into the inspection groove 16 and press down the inspection pin 15, causing it to move downwards, and it can pass through the window. The 32 observation posts 33 are precisely inserted into the inspection grooves 16 to determine if their positioning is qualified. If the positioning of the posts 33 is qualified, the first clamping device 5 and the second clamping device 9 are activated to clamp the upper edge of the new energy drive power supply housing 30, thus fixing the position of the new energy drive power supply housing 30. Then, the end caps 31 are placed on the two end cap openings at the top of the new energy drive power supply housing 30, and the end cap pressing device 4 is activated to press the end caps 31 with the copper pressure block 24, thus achieving stable clamping of the end caps 31. After that, friction welding can be performed on the end caps 31 and the end cap openings of the new energy drive power supply housing 30. After welding is completed, all clamping devices are closed, the energy drive power supply housing 30 is released, and the welded energy drive power supply housing 30 is removed from the tooling.

[0035] 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.

[0036] 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.

[0037] 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.

The descriptions of the above embodiments are 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.
