Description

Technical Field

[0001] This application belongs to the technical field of crankshaft cleaning, specifically an ultrasonic crankshaft cleaning machine. Background Technique

[0002] An ultrasonic crankshaft cleaning machine is a machine that uses ultrasonic waves to clean the crankshaft. The crankshaft is the most important component in the engine. During the operation of the engine, metal chips and carbon deposits and other impurities will be generated, which will continuously mix into the engine oil and scratch the parts, preventing a good lubricating oil film from being established on the clearance surface, and the parts will be worn. Therefore, a relatively high cleanliness requirement is imposed on the crankshaft.

[0003] At present, there are the following several methods for cleaning the crankshaft. One is the traditional manual cleaning method. First, use a copper brush to scrub the non-machined surface, then use a hair brush to scrub the machined surface, and repeatedly scrub each hole with a test tube brush. The disadvantage is that the scrubbing is not clean and the labor intensity is high.

[0004] The second is the cleaning using the current ultrasonic equipment. After ultrasonic cleaning, it still needs to be held by hand for drying, and each step still requires manual operation, resulting in low efficiency.

[0005] Therefore, an ultrasonic crankshaft cleaning machine is proposed. Content of the Utility Model

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1The utility model provides an ultrasonic crankshaft cleaning machine, which comprises a cleaning tank 1. A rack 2 is fixedly installed at the rear side inside the cleaning tank 1, and a fixing frame 3 is fixedly installed at the front side inside the cleaning tank 1. A cleaning liquid spraying row 11, a water spraying row 12 and a dryer 16 are fixedly installed along the fixing frame 3 in sequence. The cleaning liquid spraying row 11 is connected to an external cleaning liquid storage tank through a pump, and the water spraying row 12 is connected to an external water tank through a pump.

[0030] Above the rack 2, a pair of guide rods 10 are arranged. A second gear 28 is rotatably installed on the guide rods 10, and the second gear 28 meshes and moves on the upper side of the rack 2. At the front end of each guide rod 10, a pair of driving rollers 26 are rotatably installed. Above each pair of driving rollers 26, a pair of driven rollers 23 are arranged. The guide rod 10 is provided with a clamping mechanism for connecting the driving rollers 26 and the driven rollers 23. The clamping mechanism is used for clamping the crankshaft.

[0031] A motor 6 is arranged behind the cleaning tank 1. The output end of the motor 6 is provided with a transmission mechanism connecting the rack 2 and the driving rollers 26. Below the motor 6, an adjusting mechanism for adjusting the distance between the guide rods 10 is arranged. The adjusting mechanism is used for adjusting the distance between the guide rods 10, which can facilitate the clamping of crankshafts with different lengths.

[0032] Specifically, the transmission mechanism includes a first gear 5, a worm 8 and a worm gear 9. A slide rod 4 is fixedly installed at the output end of the motor 6. The slide rod 4 is fixedly installed with the first gear 5. The first gear 5 meshes and moves on the upper side of the rack 2. A chute is formed on the rear side wall of the cleaning tank 1. The slide rod 4 and the guide rods 10 both pass through the chute. A worm 8 is arranged at the front end of the slide rod 4. A worm gear 9 is fixedly installed on one of the driving rollers 26. The worm 8 and the worm gear 9 are meshed and assembled. When the motor 6 drives the slide rod 4 to rotate, the worm 8 also rotates accordingly, thereby driving the worm gear 9 to rotate. The worm gear 9 drives the connecting rod and the driving rollers 26 to rotate, achieving the effect of rotating the crankshaft.

[0033] Furthermore, sliders 27 are fixedly installed on both the slide rod 4 and the guide rods 10. The sliders 27 are slidably assembled in the chute to reduce the resistance of the slide rod 4 and the guide rods 10 when moving in the chute.

[0034] Specifically, the clamping mechanism includes a roller fixing bracket 24, a fixing rod 25, a connecting rod 13 and a spring 21. A pair of fixing rods 25 are fixedly installed on the upper side of each guiding rod 10. The same roller fixing bracket 24 is inserted and assembled with each pair of fixing rods 25. One end of the connecting rod 13 is fixedly assembled with one of the roller fixing brackets 24, and the other end of the connecting rod 13 is inserted and assembled with the other roller fixing bracket 24. A pair of driven rollers 23 are rotatably installed at the front end of the roller fixing bracket 24. The fixing rod 25 is sleeved with a spring 21. The upper end of the spring 21 is fixedly assembled with the roller fixing bracket 24, and the lower end of the roller fixing bracket 24 is fixedly assembled with the guiding rod 10. By setting the clamping mechanism, the crankshaft can be prevented from rolling during the rotary cleaning process.

[0035] Specifically, as Figure 4 shown, a clamping component is arranged between the guiding rod 10 and the roller fixing bracket 24.

[0036] Furthermore, the clamping component includes a U-shaped part 17, a limiting part 18, a fixing part 19 and a torsion spring 20. The fixing part 19 is fixedly connected with the guiding rod 10. The lower part of the fixing part 19 and the lower part of the limiting part 18 are rotationally assembled through the torsion spring 20. The limiting part 18 is serrated. The upper end of the U-shaped part 17 is fixedly connected with the roller fixing bracket 24. After the crankshaft is placed in the clamping mechanism, the upper roller fixing bracket 24 is pressed down to make the U-shaped part 17 snap into the clamping component, achieving the effect of clamping the crankshaft. The limiting part 18 is serrated, and the clamping mechanism can be adjusted according to different specifications of the crankshaft.

[0037] Specifically, the adjusting mechanism includes a one-way screw rod 7 and a locking knob 14. The motor 6 is rotationally installed with the one-way screw rod 7 through a bearing seat 29. The rear end of the guiding rod 10 close to the motor 6 is rotationally assembled with the one-way screw rod 7 through a bearing, and the rear end of the guiding rod 10 far from the motor 6 is screwed and assembled with the one-way screw rod 7. A runner is arranged at one end of the one-way screw rod 7 close to the motor 6. When the distance needs to be adjusted, the runner is rotated to move the guiding rod left and right, achieving the effect of distance adjustment.

[0038] Specifically, the one-way screw rod 7 is screwed with a locking knob 14. By setting the locking knob 14, the guiding rod can be better fixed.

[0039] Specifically, a convex block 22 is fixedly arranged at one end of the cleaning box 1 far from the sliding rod 4. The position of the convex block 22 corresponds to the limiting part 18 on the guiding rod 10. When the whole clamping mechanism moves along the rack 2 to the position of the convex block 22, the convex block 22 pushes the bottom of the limiting part 18 to open the top of the limiting part 18. Through the action of the spring 21, the U-shaped part 17 moves upward, achieving the effect of unlocking the clamping mechanism.

[0040] Specifically, a protective cover 15 is provided above the worm 8 and the worm wheel 9. The protective cover 15 is used to prevent the worm 8 and the worm wheel 9 from being sprayed with cleaning liquid and water.

[0041] Working principle:

[0042] Power-consuming components such as the motor 6 and the dryer 16 are connected to an external power source;

[0043] During operation, the crankshaft is placed in the clamping portion. The width is adjusted through the one-way screw 7 and the connecting rod 13 to adapt to the lengths of different crankshafts. The locking knob 14 is tightened, and the upper roller holder 24 is pressed down to make the U-shaped member 17 stuck in the limiting member 18 and the fixing member 19 to achieve the effect of clamping the crankshaft. The motor 6 is turned on to rotate the slide rod 4. Through the first gear 5 and the second gear 28, the entire clamping mechanism is driven to move along the direction of the rack 2. At the same time, the worm 8 rotates to drive the worm wheel 9 to rotate, driving the driving roller 26 to rotate. Through the clamping of several rollers 23, the crankshaft is driven to rotate. At the same time, the nozzles are sequentially opened to spray the cleaning agent and clean water in sequence. When the crankshaft moves to the position of the dryer 16, the dryer 16 is turned on to dry the water on the crankshaft. When the crankshaft reaches the bump 22, the bump pushes the limiting member 18 to make the clamping mechanism bounce open, facilitating the removal of the crankshaft.
