[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 As shown, this utility model provides the following technical solution: a crankshaft oil hole cleaning fixture for crankshaft processing, comprising: an operating table 1, support columns 2 installed on both sides of the upper surface of the operating table 1, a support plate 3 installed at the top of the support column 2, a linear motor 4 installed on the lower surface of the support plate 3, a bearing plate 5 installed at the output end of the linear motor 4, a crankshaft body 6 provided below the bearing plate 5, a cleaning assembly sleeved on the crankshaft body 6, annular plates 7 provided at both ends of the crankshaft body 6, multiple first threaded grooves 8 provided on both annular plates 7, a first threaded rod 9 screwed through each of the multiple first threaded grooves 8, and a clamping plate 10 installed on each of the multiple first threaded rods 9.

[0022] Furthermore, a third mounting plate 20 is connected to both sides of the lower end face of the support plate 5. A rotary motor 18 is mounted on the third mounting plate 20. The output end of the rotary motor 18 is connected to a rotating shaft 19. The end of the rotating shaft 19 away from the rotary motor 18 is connected to the second mounting plate 17.

[0023] Furthermore, the cleaning assembly includes an annular pipe 21, a flushing head 22, and a liquid pump 24. The annular pipe 21 is fitted over the crankshaft body 6, the flushing head 22 is installed on the inner wall of the annular pipe 21, a liquid guiding pipe 23 is connected to the annular pipe 21, and the liquid pump 24 is installed at the liquid inlet end of the liquid guiding pipe 23. The liquid inlet end of the liquid pump 24 is connected to an inlet pipe 25.

[0024] Through the above technical solution:

[0025] In use, the crankshaft body 6 is passed through the annular pipe 21, and then each of the first threaded rods 9 is screwed on. Through the interaction between the first threaded rods 9 and the first threaded grooves 8, the clamping plates 10 are moved until each clamping plate 10 fits against the outer wall of the crankshaft body 6, clamping the crankshaft body 6. Then, the liquid pump 24 is started, and cleaning fluid is introduced into the annular pipe 21 through the liquid inlet pipe 25. The flushing head 22 cleans the outer wall of the crankshaft body 6. During cleaning, the rotary motor 18 and the linear motor 4 are started. The rotary motor 18 drives the crankshaft body 6 through the rotating shaft 19. The second mounting plate 17 rotates, which in turn drives the crankshaft body 6 to rotate. The linear motor 4 drives the bearing plate 5 to move left and right, so that the crankshaft body 6 rotates and moves left and right at the same time. By rotating and moving left and right at the same time, it can be ensured that the cleaning fluid can evenly contact all parts of the crankshaft body 6, including hard-to-clean corners and crevices. Moreover, rotating and moving left and right at the same time can create turbulence on the surface of the crankshaft body 6, which enhances the impact force of the cleaning fluid and helps to remove oil, metal shavings and other impurities attached to the surface of the crankshaft body 6.

[0026] Please see Figures 1-3 As shown, a first mounting plate 12 is provided on one side of each of the two annular plates 7, and a first connecting plate 11 is installed between the first mounting plate 12 and the annular plate 7. A fixing plate 13 is provided on one side of each of the two first mounting plates 12, and a threaded assembly is provided between the first mounting plate 12 and the fixing plate 13. A second mounting plate 17 is provided on one side of each of the two fixing plates 13, and a second connecting plate 16 is installed between the second mounting plate 17 and the fixing plate 13.

[0027] Furthermore, the threaded assembly includes a second threaded groove 14 and a second threaded rod 15. The second threaded groove 14 is laterally opened on the fixing plate 13, and the second threaded rod 15 is screwed through the second threaded groove 14 and connected to the first mounting plate 12.

[0028] Through the above technical solution:

[0029] Before fixing both ends of the crankshaft body 6, the second threaded rods 15 on both sides are screwed on. Through the interaction of the second threaded groove 14 and the second threaded rod 15, the first mounting plate 12 is driven to rotate and move, thereby driving the annular plate 7 to move together. The distance between the two annular plates 7 is adjusted. The easily adjustable clamp allows the operator to adjust the clamping position according to the specific size and shape of the crankshaft body 6, ensuring that the crankshaft body 6 maintains the correct positioning during the processing. This helps to improve the processing accuracy, reduce the dimensional error caused by inaccurate positioning, and the easily adjustable clamp can reduce the time for changing clamps, thereby reducing production downtime and improving production efficiency.

[0030] For further details, please refer to Figure 1 As shown, a liquid storage tank 26 is provided below the annular pipe 21, and a waste liquid pipe 27 is connected below the liquid storage tank 26.

[0031] Specifically, the main function of the storage tank 26 is to collect waste liquid after cleaning, including wastewater, chemicals and oil generated during the cleaning process. By collecting the waste liquid in a centralized manner, it can prevent the waste liquid from being directly discharged into the environment and avoid pollution to soil, water sources and other sources. The waste liquid pipeline 27 facilitates the discharge of wastewater and ensures that the waste liquid can be effectively collected and treated.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
