[0001] This application relates to the field of installation tooling technology, and in particular to a pre-installation tooling for automotive exhaust fan blades. Background Technology

[0002] The automotive exhaust fan blade pre-installation fixture is suitable for scenarios where automotive exhaust fan blades are precisely pre-installed in automotive repair or manufacturing plants. It helps workers efficiently and stably complete the positioning and fixing of the blades, ensuring the quality and efficiency of exhaust fan assembly.

[0003] Regarding the aforementioned technologies, the inventors believe that the existing technology requires repeated calibration and adjustment of the blade position when installing automotive exhaust fan blades. This is not only time-consuming and labor-intensive, but also prone to substandard installation accuracy due to improper operation, which affects the working efficiency and performance of the exhaust fan. In general, the existing automotive exhaust fan blade installation process still has technical problems such as cumbersome operation, difficult adjustment, and insufficient installation accuracy. Utility Model Content

[0004] The purpose of this application is to provide a pre-installation fixture for automotive exhaust fan blades to improve the problems of cumbersome operation, difficult adjustment, and insufficient installation accuracy.

[0005] The technical solution for the pre-installation fixture for automotive exhaust fan blades provided in this application is as follows:

[0006] A pre-installation fixture for automotive exhaust fan blades includes a base plate. A locking mechanism is fixedly mounted on the upper surface of the base plate. An installation mechanism is fixedly mounted at one end of the base plate. The installation mechanism includes a fixing frame, one side of which is fixedly connected to one end of the base plate. Two sliding rods are fixedly mounted on one side of the fixing frame, and a return spring is sleeved on the outer side of each sliding rod. A rotating frame is fixedly mounted on the side of the fixing frame away from the base plate. An installation handle is rotatably mounted on one side of the rotating frame. Pull rings are rotatably mounted on both sides of the installation handle. A sliding base is provided at one end of the base plate. One side of the sliding base is slidably connected to a sliding rod. A pull buckle is fixedly mounted on the lower surface of the sliding base, and the pull buckle engages with the pull rings.

[0007] By adopting the above technical solution and through the installation mechanism, the automotive exhaust fan blades can be installed quickly and stably. This not only facilitates operation and adjustment but also ensures accuracy and stability during the installation process. Furthermore, the blades can automatically reset after installation, thus improving work efficiency.

[0008] Optionally, the engaging mechanism includes a positioning base, the lower surface of which is fitted against the upper surface of the base plate, an inner positioning frame engaged on the upper surface of the positioning base, an outer shell engaged on the upper surface of the inner positioning frame, an engaging base fixedly mounted on the upper surface of the base plate, a blade assembly engaged on the upper surface of the engaging base, a sliding inner frame engaged on one side of the blade assembly, and the lower surface of the sliding inner frame engaged with the upper surface of the sliding base.

[0009] By adopting the above technical solution, the locking mechanism can quickly limit and install the inner frame and outer shell, while maintaining stability during blade assembly installation to achieve the required installation accuracy.

[0010] Optionally, the lower surface of the base plate is fixedly provided with a plurality of anti-slip pads arranged in a rectangular array.

[0011] By adopting the above technical solution, the anti-slip foot pads increase the stability of the tooling during use and prevent the tooling from sliding or tilting, which would lead to a decrease in installation accuracy.

[0012] Optionally, the sliding base has two symmetrically distributed sliding grooves on one side, and the sliding grooves are slidably connected to the sliding rod.

[0013] By adopting the above technical solution, the sliding connection design of the sliding groove and the sliding rod enables the sliding base to slide smoothly on one side of the fixed frame, ensuring the smoothness and accuracy of the installation process.

[0014] Optionally, two symmetrically distributed limiting blocks are engaged on the upper surface of one end of the base plate. One side of the limiting block slides against one side of the sliding base. Two limiting bolts are inserted into the upper surface of the limiting block, and the limiting bolts are fixedly engaged with the base plate.

[0015] By adopting the above technical solution, the setting of the limiting block and the limiting bolt effectively limits the sliding range of the sliding base, preventing the sliding base from deviating from the track or sliding excessively during the sliding process.

[0016] Optionally, two fixing bolts are inserted into the upper inner wall of the buckle, and the fixing bolts are fixedly engaged with the sliding base.

[0017] By adopting the above technical solution, the fixing bolts firmly fix the buckle to the sliding base, ensuring the stability and reliability of the buckle and pull ring engagement connection.

[0018] Optionally, the upper surface of the base plate is fixedly provided with multiple locking rods, which are respectively attached to the lower surfaces of the positioning base and the engaging base.

[0019] By adopting the above technical solution, the locking rod effectively supports and positions the positioning base and the locking base, ensuring their stability and accuracy during use.

[0020] Optionally, the upper surface of the locking base is provided with a locking groove, which slides in conjunction with the blade assembly.

[0021] By adopting the above technical solution, the sliding fit design between the locking groove and the blade assembly allows the blade assembly to easily slide on the locking base and be positioned accurately.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This utility model achieves rapid and stable installation of automotive exhaust fan blades through an installation mechanism. It not only facilitates operation and adjustment but also ensures accuracy and stability during the installation process.

[0028] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0029] Example

[0030] A pre-installation fixture for automotive exhaust fan blades, referring to Figure 1 and Figure 2The base plate 1 serves as the supporting foundation for the entire tooling. A locking mechanism 3 is fixedly installed on its upper surface for positioning and fixing the blade assembly 33. At the same time, an installation mechanism 2 is fixedly installed at one end of the base plate 1 for the installation operation of the blade assembly 33. The installation mechanism 2 specifically includes a fixing frame 20 fixedly connected to one end of the base plate 1. The fixing frame 20 is provided with two sliding rods 24. A return spring 25 is sleeved on the outside of the sliding rods 24 to provide elastic return force. A rotating frame 21 is provided on the side of the fixing frame 20 away from the base plate 1. An installation handle 22 is rotatably provided on the rotating frame 21. Pull rings 23 are rotatably provided on both sides of the installation handle 22. A sliding base 28 is provided on the base plate 1 and is slidably connected to the sliding rods 24. A pull buckle 202 is fixedly provided on the lower surface of the sliding base 28. The pull buckle 202 and the pull ring 23 can be locked together.

[0031] Reference Figure 2 The anti-slip foot pad 4 increases the stability of the tooling during use, preventing the tooling from sliding or tilting and causing a decrease in installation accuracy. The sliding connection design between the sliding groove 29 and the sliding rod 24 allows the sliding base 28 to slide smoothly on one side of the fixed frame 20, ensuring smoothness and accuracy during installation. The limit block 26 and the limit bolt 27 effectively limit the sliding range of the sliding base 28, preventing the sliding base 28 from derailing or sliding excessively during the sliding process. The fixing bolt 201 firmly fixes the pull buckle 202 to the sliding base 28, ensuring the stability and reliability of the engagement connection between the pull buckle 202 and the pull ring 23.

[0032] Reference Figure 3 The engaging mechanism 3 includes a positioning base 30, which is attached to the upper surface of the base plate 1. A positioning inner frame 31 is engaged on the positioning base 30, and a shell 32 is engaged on the positioning inner frame 31 to form an external support for the blade assembly 33. A engaging base 36 is also fixed on the base plate 1, and the blade assembly 33 is engaged on the engaging base 36. A sliding inner frame 34 is engaged on one side of the blade assembly 33, and the lower surface of the sliding inner frame 34 is engaged with the upper surface of the sliding base 28, thereby achieving stable positioning of the blade assembly 33 during installation.

[0033] Reference Figure 3 The locking lever 37 effectively supports and positions the positioning base 30 and the locking base 36, ensuring their stability and accuracy during use. The sliding fit design between the locking groove 35 and the blade assembly 33 allows the blade assembly 33 to easily slide on the locking base 36 and be positioned accurately.

[0034] The implementation principle of this application embodiment is as follows: When using the installation mechanism 2, the blade assembly 33 is first placed on the engaging base 36. Then, by rotating the installation handle 22, the pull ring 23 is moved, thereby driving the sliding inner frame 34 on the sliding base 28 to move towards the blade assembly 33 through the engaging connection between the buckle 202 and the pull ring 23. At the same time, the return spring 25 stores energy under the action of elasticity, and the sliding base 28 slides smoothly along the sliding rod 24. The sliding inner frame 34 can then engage and fix with the blade assembly 33. Afterward, the blade assembly 33 continues to move and slide under the push of the sliding inner frame 34 until it engages and fixes with the positioning inner frame 31. The installed inner frame is then removed. Finally, the installation handle 22 is released and the installation mechanism 2 is reset under the action of the return spring 25, thereby completing the installation of the blade assembly 33.

[0035] When using the locking mechanism 3, firstly, the positioning base 30 is placed on the base plate 1 and supported and positioned by the locking rod 37. Then, the positioning inner frame 31 is locked onto the positioning base 30, and the outer shell 32 is locked onto the positioning inner frame 31 to form the external support of the blade assembly 33. Next, the blade assembly 33 is placed in the locking groove 35 of the locking base 36. Finally, the sliding inner frame 34 is locked and installed on the upper surface of the sliding base 28 to complete the installation and positioning of the inner frame, ensuring that the blade assembly 33 remains stable and achieves the required installation accuracy during the installation process.
