[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] The present invention provides Figure 1-8 A wet dual clutch appearance inspection tool shown in the figure comprises a tray 1 for placing the wet dual clutch, a central shaft 12 is provided on both sides of the tray 1, and the two central shafts 12 are symmetrically arranged on the left and right sides of the tray 1, and the end of the central shaft 12 away from the tray 1 is rotatably connected to a side support plate 3; Two fixing blocks 7 are provided at the top of the tray 1, and a quick handle 8 is provided on the fixing block 7. The quick handle 8 can control the fixing block 7 to clamp the wet dual clutch. A positioning wheel 10 is fixedly provided at the outer end of one of the central shafts 12, and a plurality of pin positioning holes 11 are opened at the outer end of the positioning wheel 10. A locking pin 9 is provided at the top of one of the side support plates 3, and the bottom end of the locking pin 9 can be inserted into one of the pin positioning holes 11.

[0021] A base 5 is provided at the bottom of the tray 1 , the bottom end of the side support plate 3 is fixedly connected to the top end of the base 5 , two reinforcing ribs are fixedly provided on the side support plate 3 , and a cushion 4 is fixedly provided on the top end of the base 5 .

[0022] First, rotate the tray 1 to a horizontal state, open the quick handle 8, and make the fixed block 7 become a loose and rotatable state, then place the clutch to be inspected on the top of the tray 1, and at the same time rotate the fixed block 7 back to the original position and merge the quick handle 8, lock the fixed block 7, and the fixed block 7 clamps and fixes the clutch. At this time, the clutch can be inspected from the front. During the inspection, the locking pin 9 is inserted downward into one of the pin positioning holes 11, so that the positioning wheel 10 and the central shaft 12 cannot rotate, and the position of the tray 1 and the clutch is thus fixed; When the front inspection is completed, if the inspection angle needs to be adjusted, the locking pin 9 is pulled out upward to release the restrictions on the positioning wheel 10 and the center shaft 12, so that the center shaft 12 can rotate, thereby driving the tray 1 and the clutch to rotate, so as to adjust the inspection angle. The positioning wheel 10 will rotate synchronously with the center shaft 12. When it reaches the detection position, the corresponding pin positioning hole 11 on the positioning wheel 10 will also select the locking pin 9, so that the locking pin 9 automatically probes downward into the pin positioning hole 11, thereby fixing the angle of the pin positioning hole 11 again. This method can more conveniently perform multi-angle appearance inspections, improve inspection efficiency, save time and effort, reduce the probability of safety accidents, avoid secondary collisions of the clutch, and improve the pass rate of the clutch appearance inspection.

[0023] While controlling the rotation of the tray 1, it is also necessary to adjust the resistance during the rotation, such as Figure 3-5 As shown, a resistance wheel 15 is fixedly provided at the outer end of another central shaft 12, and a resistance mechanism 16 is provided at the bottom of the resistance wheel 15. The resistance mechanism 16 includes a mounting plate 1601, and the mounting plate 1601 is bolted to the side support plate 3 on the corresponding side.

[0024] The mounting plate 1601 is provided with an adjusting screw 1604 that penetrates the mounting plate 1601. The adjusting screw 1604 is connected to the mounting plate 1601 by threads. After the adjusting screw 1604 is rotated, it can move up and down relative to the mounting plate 1601. A knob 1605 is fixed at the bottom end of the adjusting screw 1604, and the knob 1605 can drive the adjusting screw 1604 to rotate; The top of the adjusting screw 1604 is rotatably connected to a lifting block 1602 , the notch at the top of the lifting block 1602 matches the bottom of the resistance wheel 15 , an anti-skid gasket 1603 is fixed inside the notch of the lifting block 1602 , and the anti-skid gasket 1603 is in contact with the resistance wheel 15 .

[0025] When adjusting the angle of the tray 1, the central axis 12 rotates with the rotation of the tray 1. During the rotation process, once the operator lets go, the tray 1 will rotate freely under the action of the clutch and its own weight until the locking pin 9 enters one of the pin positioning holes 11 to stop. The tray 1 and the clutch are both made of metal and are heavy. The impact force during free rotation is large. The locking pin 9 will be subjected to a large impact force to stop it during free rotation, and the locking pin 9 is very easy to bend. Therefore, a resistance wheel 15 is fixed on another central axis 12, and a resistance mechanism 16 is arranged under the resistance wheel 15. By rotating the adjusting screw 1604, the lifting block 1602 can be pushed to squeeze the resistance wheel 15 upward, so that the friction between the resistance wheel 15 and the anti-slip gasket 1603 increases. The friction force makes the rotation of the central axis 12 damped, and the damping size can be freely adjusted according to actual conditions. Appropriate damping can play a buffering role when the tray 1 rotates freely, reduce the impact force of the tray 1, and prevent the locking pin 9 from bending due to impact.

[0026] In order to save more effort when controlling the rotation of the tray 1, Figure 1 , 8 As shown, the tray 1 is fixedly provided with tray handles 14 on both the front and rear sides, and a detachable labor-saving component 2 is provided on one of the tray handles 14, and the labor-saving component 2 includes a clamping plate 201, and the clamping plate 201 is clamped on the outer end of the tray handle 14; A handle 202 is provided on one side of the clamping plate 201 away from the tray 1 , and two telescopic rods 203 are provided between the handle 202 and the clamping plate 201 , with two ends of the telescopic rods 203 fixedly connected to the handle 202 and the clamping plate 201 , respectively.

[0027] The clutch itself weighs about 10kg, plus the weight of the tray 1, it will take a lot of force to control the rotation of the tray 1 and the clutch. Under normal circumstances, the tray handle 14 can be used to manually control the rotation of the tray 1. If this method is more strenuous, the splint 201 can be clamped on the outer end of the tray handle 14, and the handle 202 can be used to drive the telescopic rod 203 and the splint 201 to rotate around the central axis 12, thereby driving the tray 1 and the clutch to rotate. This method of control can increase the force arm of the driving force, making it easier to control the rotation of the tray 1. On this basis, the telescopic rod 203 can be controlled to be retracted and the force arm can be adjusted by itself, which is more practical.

[0028] In order to relieve the force on the locking spring pin 9, Figure 1 , 3 As shown in , 6 and 7, two tension components 6 are provided under the tray 1, and the two tension components 6 are symmetrically arranged front to back. The tension component 6 includes a tension rope 601, and a hook 602 is fixedly provided at one end of the tension rope 601 facing the tray 1. Two hanging rings 13 are fixedly provided at the bottom end of the tray 1, and the two hooks 602 are hung on the two hanging rings 13 respectively.

[0029] An upper sleeve 606 is fixedly provided at one end of the tension rope 601 away from the tray 1 , and a threaded sleeve 605 is rotatably connected to the other end of the upper sleeve 606 away from the tray 1 through a bearing.

[0030] The tension assembly 6 further includes a lower sleeve 603, the bottom end of which is hinged to the top end of the base 5, a spring 607 is fixed on the inner wall of the lower sleeve 603, and a center rod 608 is fixed at one end of the spring 607; The top end of the center rod 608 extends to the interior of the upper sleeve 606, and the threaded sleeve 605 is threadedly sleeved on the outer end of the center rod 608. The outer end of the lower sleeve 603 is provided with a scale groove 604, and one side of the scale groove 604 is provided with a scale marked on the outer end of the lower sleeve 603, and the stretched length of the spring 607 can be displayed by the scale.

[0031] The two tension components 6 are respectively arranged on the front and rear sides of the tray 1. The hooks 602 of the two tension components 6 can be hung on the two hanging rings 13 respectively. The threaded sleeve 605 is rotated. Under the action of the thread, the rotation of the threaded sleeve 605 can control the center rod 608 to move inside the upper sleeve 606, thereby driving the spring 607 to stretch. The tension rope 601 is pulled by the elastic force of the spring 607 to tighten the tension rope 601, thereby making the tension component 6 pull the tray 1 as a whole. The longer the spring 607 is stretched, the greater the pulling force of the tension component 6 on the tray 1. The stretching length of the spring 607 can be accurately grasped through the scale groove 604 and the scale, thereby accurately understanding the pulling force of the tension component 6.

[0032] When the tray 1 is horizontal, the pulling forces of the two pulling force components 6 are controlled to be equal, and the two pull the tray 1 one after the other, and the pulling forces are balanced with each other, which helps to keep the tray 1 in a horizontal state. When adjusting the angle of the tray 1, in order not to affect the rotation of the tray 1, the hook 602 needs to be removed from the hanging ring 13; When the tray 1 tilts forward, although the locking pin 9 fixes the tray 1, under the weight of the tray 1 and the clutch, the tray 1 still tends to rotate further forward. Therefore, the locking pin 9 is under continuous stress at this time. For this reason, the rear tension component 6 is connected to the hanging ring 13, and the front tension component 6 is in an idle state. The rear tension component 6 pulls the tray 1 backward to offset the weight of the tray 1 and the clutch, reduce the stress on the locking pin 9, and prevent the locking pin 9 from bending and deforming due to continuous stress. When the tray 1 tilts backward, the front tension component 6 is used to pull the tray 1 forward, and the rear tension component 6 is idle. The principle is the same as when it tilts forward.

[0033] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
