[0002] In the production process of an engine fan bracket, a high-quality painting process is particularly crucial, which directly relates to the overall performance and reliability of the engine. At present, paint spraying and baking integrated equipment has been widely used in the industry. Such equipment integrates the functions of spraying and drying, significantly improving production efficiency and painting quality.

[0003] However, there is a common problem in the existing paint spraying and baking integrated equipment: the manual loading and unloading operation is cumbersome and inefficient. Specifically, in the traditional operation process, workers need to manually install the engine fan bracket to be painted onto the fixture, then send it into the paint spraying room for spraying, and after spraying, transfer it to the baking room for drying. This series of operations not only takes time and effort, but also easily causes problems such as unstable fixture installation and uneven coating due to human factors, affecting the quality and consistency of the final product. In addition, long-term manual operation is likely to cause occupational health and safety risks, increasing the operating costs of the enterprise. Content of the Utility Model

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] Figure 1 This is a schematic diagram of the engine fan bracket, which is directly fixed to the engine main shaft when working, and transmits power through the belt pulley to drive auxiliary equipment such as the generator.

[0021] Reference Figure 2 , Figure 3 The utility model provides an engine fan bracket coating hanger, which is mainly composed of a tightening ring 1, a torsion spring bracket 2, a top cover 3, a square tube 4 and a tension spring 5.

[0022] The torsion spring bracket 2 is provided with a plurality of torsion springs 201, and the end of the torsion arm of the torsion spring 201 is folded toward the outside of the torsion spring bracket 2. The tightening ring 1 is used to wrap the torsion spring bracket 2 and is provided with a top cover 3. After the tightening ring 1 moves downward, the torsion arm of the torsion spring 201 is folded toward the inside of the tightening ring 1, so that it can be conveniently inserted into the bottom through hole of the fan bracket. After the tightening ring 1 is reset, the torsion arm of the torsion spring 201 is stretched outward, and the folded part at the end prevents the torsion arm of the torsion spring 201 from escaping from the bottom through hole of the fan bracket, thereby grabbing the fan bracket. A limit block 101 is provided at the lower end of the tightening ring 1 to limit the downward movement distance of the torsion spring bracket 2 and prevent it from escaping from the tightening ring 1.

[0023] The lower end of the square tube 4 is connected to the torsion spring bracket 2, and the upper end is equipped with a roller 6 that matches the conveyor line of the spraying equipment; the push plate 301 on the top cover 3, the square tube 4 is provided with a vertical sliding hole 401, the push plate 301 passes through the vertical sliding hole 401, one end of the tension spring 5 is connected to the top cover 3, and the other end is connected to the wheel axle of the roller 6.

[0024] During operation, after the square tube 4 moves to the loading position along the conveyor line of the spraying equipment, the power component (cylinder, oil cylinder, etc.) is inserted into the square tube 4 to push the push plate 301 to move downward, thereby driving the tightening ring 1 to tighten the torsion arm of the torsion spring 201, and pushing the torsion spring bracket 2 to move downward and insert into the bottom through hole of the fan bracket. After the power component contracts, the tension spring 5 drives the top cover 3 to move up and reset, thereby realizing automatic loading of the fan bracket.

[0025] Reference Figures 4 - 6 As shown in Figures 4 - 6 , a horizontal strip-shaped through hole 203 is also formed in the torsion spring bracket 2. A locking rod 205 is arranged in the strip-shaped through hole 203. A holding spring 204 is arranged between the locking rod 205 and the torsion spring bracket 2. The holding spring 204 holds the locking rod 205 at one end of the strip-shaped through hole 203. A Z-shaped sliding hole 402 is formed in the square pipe 4. The locking rod 205 passes through the Z-shaped sliding hole 402. In the normal state, the locking rod 205 is held in the upper horizontal section of the Z-shaped sliding hole 402 under the action of the holding spring 204, fixing the torsion spring bracket 2 on the square pipe 4. A guide rod 302 and a lock catch 304 are installed on the top cover 3. A guide hole 202 matching with the guide rod 302 is also formed in the torsion spring bracket 2. A return spring 303 is installed on the guide rod 302. The lower end of the lock catch 304 is provided with an inclined surface inclined towards the vertical section of the Z-shaped sliding hole 402. A clamping groove 305 matching with the locking rod 205 is arranged at the end of the inclined surface. The clamping groove 305 is opposite to the vertical section of the Z-shaped sliding hole 402.

[0026] During feeding, the top cover 3 moves downward along the square pipe 4 under the push of the power component. At this time, the locking rod 205 is held in the upper horizontal section of the Z-shaped sliding hole 402. The beam collecting ring 1 moves downward relative to the torsion spring bracket 2, and the torsion arms of the beam collecting torsion spring 201 are collected and the return spring 303 is compressed. When the lower end of the lock catch 304 contacts the locking rod 205 and pushes it along, the inclined surface at the lower end of the lock catch 304 slides towards the vertical section of the Z-shaped sliding hole 402. When the locking rod 205 is engaged in the clamping groove 305, the beam collecting ring 1 and the torsion spring bracket 2 are locked, thus maintaining the collected state of the torsion arms of the torsion spring 201. The power component pushes the combination of the beam collecting ring 1 and the torsion spring bracket 2 to move downward along the vertical section of the Z-shaped sliding hole 402 to complete the process of inserting the torsion arms of the torsion spring 201 into the bottom through hole of the fan bracket.

[0027] A wedge block 403 with an inclined surface facing the lower horizontal section of the Z-shaped sliding hole 402 is arranged at the bottom of the square pipe 4. When the locking rod 205 moves to the lower end along the vertical section of the Z-shaped sliding hole 402, the locking rod 205 is disengaged from the clamping groove 305 under the guiding action of the wedge block 403, thus realizing the unlocking of the beam collecting ring 1 and the torsion spring bracket 2. After the power component retracts, the beam collecting ring 1 moves upward under the action of the tension spring 5, and the torsion spring bracket 2 is held at the lower end of the square pipe 4 under the action of the return spring 303. The torsion arms of the torsion spring 201 are reset and engaged with the fan bracket. After the torsion spring bracket 2 contacts the limit block 101, it rises under the drive of the beam collecting ring 1. The locking rod 205 returns to the upper horizontal section of the Z-shaped sliding hole 402 under the action of the holding spring 204, completing the automatic feeding of the fan bracket. During discharging, the same operation is performed. The fan bracket falls off under the action of gravity, that is, the discharging operation is completed.

[0028] The specific implementation manners of the present utility model described above do not constitute a limitation on the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model shall be included in the protection scope of the claims of the present utility model.
