[0002] In the automotive manufacturing industry, the engine hood is one of the key appearance parts, and its processing accuracy and surface quality directly affect the overall appearance and performance of the vehicle. In traditional processing technology, CNC (computer numerical control) equipment is widely used for precise forming and cutting of the hood. However, in this process, due to the high-speed cutting of metal materials (especially aluminum alloys), a large number of small and dense metal chips will be generated. These aluminum chips are very easy to adhere to the surface of the processing fixture and the structural gaps. The current cleaning method mostly relies on handheld spray guns for cleaning, which is not only time-consuming and labor-intensive, but also difficult to completely remove the residues in tiny corners.

The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] like Figures 1 to 4 As shown, the self-cleaning fixture for processing an automobile engine hood of the utility model comprises:

[0024] A mounting base 1, two groups of mounting bases 1 are respectively arranged at both ends of the fixture, threaded rods 2 are respectively arranged in two groups of through holes coaxially mounted on the two groups of mounting bases 1, threaded holes of moving parts 3 are respectively arranged in the two groups of threaded rods 2, a conducting part 4 is arranged in the axial hole of the moving part 3, a mounting part 5 is arranged in the inner cavity of the conducting part 4, a diffuser pipe 6 is arranged at one end of the mounting part 5, and a plurality of groups of high-pressure nozzles 7 are equidistantly arranged on the diffuser pipe 6;

The driving assembly cooperates with the conductive part 4 to make the mounting part 5 drive the high-pressure nozzle 7 on the heat dissipation pipe 6 to rotate. The multiple groups of high-pressure nozzles 7 on the diffuser pipe 6 move and rotate at the same time, which can automatically perform fast and comprehensive air blowing cleaning on the fixture surface before processing, ensuring that the product is in a completely free state during installation, while increasing the cleaning interval and reducing the cleaning blind area. The structure composed of the mounting base 1, the threaded rod 2, the moving part 3 and the conductive part 4 is a modular design, which is convenient for daily maintenance and quick replacement of damaged parts, and also provides convenience for future technology upgrades, with high cleaning efficiency and small cleaning blind areas.

[0026] like Figures 1 to 4As shown, as a preferred solution, the driving assembly includes a first sprocket 9 coaxially arranged on the threaded rod 2, and a first chain 10 is meshed and installed on two groups of first sprockets 9; the two groups of threaded rods 2 are synchronously rotated in the same direction by meshing the first chain 10 with the two groups of first sprockets 9, so as to maintain the stability of the moving process of the moving part 3, and adopt chain transmission instead of complex mechanical linkage structure, which not only simplifies the design and reduces the difficulty of assembly, but also the chain itself is highly replaceable and easy to maintain and adjust the tension, thereby reducing the maintenance cost and failure rate in long-term use.

[0027] like Figures 1 to 4 As shown, as a preferred solution, the drive assembly also includes a servo motor 11 arranged on a group of mounting bases 1, a power shaft 12 is coaxially arranged at the output end of the servo motor 11, a first worm 13 is coaxially mounted on the power shaft 12, a first worm wheel 14 is coaxially arranged on a group of threaded rods 2, and the first worm 13 is meshed and connected with the first worm wheel 14; the introduction of the servo motor 11 greatly improves the accuracy and dynamic response speed of the system for motion control. The servo motor, with its high-precision position control, speed control and torque control capabilities, ensures that the rotation of the threaded rod 2 and the mounting member 5 is both rapid and accurate, meeting the dual requirements of time and effect of the self-cleaning process before processing, the first worm 13 is coaxially installed at the output end of the servo motor 11 through the power shaft 12, and the servo motor 11 drives the threaded rod 2 to rotate through the meshing of the first worm 13 and the first worm wheel 14, and the transmission is a speed reduction transmission.

[0030] like Figures 1 to 4As shown, as a preferred solution, a driving shaft 21 is provided at the slots of the two groups of mounting bases 1, and the driving shaft 21 is transmission-connected with the polygonal inner cavity of the second worm 19, a driven bevel gear 22 is coaxially provided on the driving shaft 21, and a driving bevel gear 23 is coaxially provided on the power shaft 12, and the driving bevel gear 23 is meshingly transmission-connected with the driven bevel gear 22; the driving bevel gear 23 is meshed with the driven bevel gear 22 to enable the power shaft 12 to drive the driving shaft 21 to rotate, and the driving shaft 21 cooperates with the polygonal inner cavity of the second worm 19 so that the transmission relationship between the second worm 19 and the driving shaft 21 remains unchanged after the position is moved, and this structure enables the servo motor 11, a power source, to synchronously drive the high-pressure nozzle 7 to move and rotate at the same time.

[0031] like Figures 1 to 4 As shown, as a preferred solution, a screw 8 is provided at the threaded through hole of the conductive member 4, and the screw 8 is in contact and connected with the mounting member 5; the connection position of the mounting member 5 and the conductive member 4 is locked by the screw 8, and the working height of the high-pressure nozzle 7 is adapted by adjusting the connection position of the mounting member 5 and the conductive member 4.

[0032] like Figures 1 to 4 As shown, as a preferred solution, a protective member 24 is provided on the movable member 3, and the transmission shaft 15, the second sprocket 16, the second worm 19 and the second worm wheel 20 are all arranged inside the protective member 24; the protective member 24 effectively isolates the external environment from direct contact with the internal precision transmission components, prevents machining chips, cutting fluid or other debris generated during the machining process from entering the transmission system, reduces the probability of component wear and failure, and improves the operating safety of the entire clamping system.

[0035] like Figures 1 to 4 As shown, as a preferred solution, its working process is as follows:

[0036] First, the user adjusts the height of the mounting member 5 according to actual needs, and adjusts the working height of the high-pressure nozzle 7 by the screw 8. When cleaning, the servo motor 11 receives the control signal and starts, and drives the first worm 13 to rotate through the power shaft 12. The first worm 13 is meshed with the first worm wheel 14, and the rotational motion of the servo motor 11 is converted into the linear motion of the threaded rod 2, so that the moving member 3 is translated along the set trajectory. At the same time, the active bevel gear 23 on the power shaft 12 is meshed with the driven bevel gear 22 on the drive shaft 21, driving the second worm 19 to rotate, and then the second worm 19 is meshed with the second worm wheel 20 to drive the transmission shaft 15 to rotate. The transmission shaft 15 is connected to the conductive member 4 through the second sprocket 16 and the second chain 17, driving the multiple groups of high-pressure nozzles 7 on the conductive member 4 to rotate. At the same time, the high-pressure gas is input into the mounting member 5 through the guide pipe 27 through the air supply unit, and then evenly sprayed by the high-pressure nozzle 7, aiming at the surface of the fixture for all-round and dead-angle blowing cleaning. After the cleaning before processing is completed, the system stops running and the servo motor 11 stops outputting power.
