Description

Technical Field

[0001] This utility model relates to the field of appearance inspection tooling technology, specifically to a wet dual-clutch appearance inspection tooling. Background Technology

[0002] Wet dual-clutch transmissions are a widely used automotive component, characterized by their stable structure, smooth shifting, high transmission efficiency, and direct power output.

[0003] Wet dual clutches are generally mass-produced on factory production lines and require heat treatment processes such as quenching and tempering, as well as cutting processes such as turning and milling, to ensure the strength and precision of the workpiece.

[0004] Wet dual clutches are made of metal and are easily scratched by bumps during the production process. Therefore, after the product comes off the production line, it still needs to be visually inspected to avoid defective products.

[0005] However, the average weight of a clutch is about 10kg, which is quite strenuous to move. Handling it manually can easily cause muscle injuries, lumbar muscle strain and other diseases. There is also a risk that the clutch may fall and injure someone. In addition, it is difficult to achieve a 360° all-round inspection. If a 360° inspection is required, the clutch must be placed on the table and picked up again, which poses a risk of bumping and knocking during the second placement. Utility Model Content

[0006] The purpose of this invention is to provide a wet dual-clutch appearance inspection fixture. By rotating the tray to adjust the angle of the clutch, the appearance inspection of the clutch can be carried out at different angles.

[0011] Furthermore, the mounting plate is provided with an adjusting screw that penetrates the mounting plate. The adjusting screw is connected to the mounting plate by a thread. After the adjusting screw is rotated, it can move up and down relative to the mounting plate. A knob is fixedly provided at the bottom end of the adjusting screw. The adjusting screw can be rotated by rotating the knob.

[0012] The top of the adjusting screw is rotatably connected to a lifting block. The notch at the top of the lifting block matches the bottom of the resistance wheel. An anti-slip pad is fixedly installed inside the notch of the lifting block, and the anti-slip pad is in contact with the resistance wheel.

[0013] Furthermore, tray handles are fixedly provided on both the front and rear sides of the tray, and one of the tray handles is provided with a detachable labor-saving component, which includes a clamping plate that is snapped onto the outer end of the tray handle;

[0014] A handle is provided on the side of the clamp away from the tray. Two telescopic rods are provided between the handle and the clamp, and the two ends of the telescopic rods are fixedly connected to the handle and the clamp respectively.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] This utility model provides, for example Figure 1-8 The present invention relates to a wet dual-clutch appearance inspection fixture, which includes a tray 1 for placing a wet dual-clutch. The tray 1 has a central shaft 12 on both sides, and the two central shafts 12 are symmetrically arranged on the left and right sides of the tray 1. The end of the central shaft 12 away from the tray 1 is rotatably connected to a side support plate 3.

[0036] The top of the tray 1 is provided with two fixing blocks 7, and the fixing blocks 7 are provided with quick handles 8. The quick handles 8 can control the fixing blocks 7 to clamp the wet dual clutch. One of the central shafts 12 is fixed with a positioning wheel 10 at its outer end. The outer end of the positioning wheel 10 is provided with multiple pin positioning holes 11. One of the side support plates 3 is provided with a locking spring pin 9 at its top end. The bottom end of the locking spring pin 9 can be inserted into one of the pin positioning holes 11.

[0037] The bottom of the tray 1 is provided with a base 5, 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 soft pad 4 is fixedly provided on the top end of the base 5.

[0038] First, rotate tray 1 to a horizontal position and open quick handle 8, so that fixing block 7 becomes loose and rotatable. Then, place the clutch to be inspected on top of tray 1, and rotate fixing block 7 back to its original position and close quick handle 8 to lock fixing block 7. Fixing block 7 clamps and fixes the clutch. At this time, the clutch can be inspected from the front. During the inspection, locking spring pin 9 is inserted downward into one of the pin positioning holes 11, so that positioning wheel 10 and central shaft 12 cannot rotate, and the positions of tray 1 and clutch are thus fixed.

[0039] After the frontal inspection is completed, if it is necessary to adjust the inspection angle, pull the locking spring pin 9 upward to release the restriction on the positioning wheel 10 and the central shaft 12, allowing the central shaft 12 to rotate, which in turn drives the tray 1 and the clutch to rotate, thereby adjusting the inspection angle. The positioning wheel 10 will rotate synchronously with the central shaft 12. When it reaches the inspection position, the corresponding pin positioning hole 11 on the positioning wheel 10 will also be positioned at the locking spring pin 9, so that the locking spring 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 inspection, improve inspection efficiency, save time and effort, reduce the probability of safety accidents, avoid secondary collisions with the clutch, and improve the pass rate of clutch appearance inspection.

[0040] While controlling the rotation of tray 1, it is also necessary to adjust the resistance during its rotation, such as... Figure 3-5 As shown, another central shaft 12 has a resistance wheel 15 fixedly installed at its outer end. The resistance wheel 15 has a resistance mechanism 16 at its bottom. The resistance mechanism 16 includes a mounting plate 1601, which is bolted to the side support plate 3 on the corresponding side.

[0041] The mounting plate 1601 is provided with an adjusting screw 1604 that passes through the mounting plate 1601. The adjusting screw 1604 is connected to the mounting plate 1601 by a thread. After the adjusting screw 1604 is rotated, it can move up and down relative to the mounting plate 1601. A knob 1605 is fixedly provided at the bottom end of the adjusting screw 1604. The knob 1605 can drive the adjusting screw 1604 to rotate.

[0042] The top end 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 end of the resistance wheel 15. An anti-slip pad 1603 is fixedly provided inside the notch of the lifting block 1602, and the anti-slip pad 1603 is in contact with the resistance wheel 15.

[0043] When adjusting the angle of tray 1, the central shaft 12 rotates with the rotation of tray 1. During the rotation, once the operator releases their hand, tray 1 will rotate freely under the action of the clutch and its own weight until the locking spring pin 9 is inserted into one of the pin positioning holes 11 to stop it. Tray 1 and the clutch are both made of metal and are relatively heavy. The impact force when rotating freely is relatively large. When the locking spring pin 9 stops it during its free rotation, it will bear a large impact force, and the locking spring pin 9 is very easy to bend as a result.

[0044] Therefore, a resistance wheel 15 is fixed on another central shaft 12, and a resistance mechanism 16 is set below the resistance wheel 15. By rotating the adjusting screw 1604, the lifting block 1602 can be pushed upward to press the resistance wheel 15, which increases the friction between the resistance wheel 15 and the anti-slip pad 1603. The friction makes the rotation of the central shaft 12 damped, and the damping size can be freely adjusted according to the actual situation. 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 spring pin 9 from bending due to impact.

[0045] To make controlling the rotation of tray 1 easier, such as Figure 1 , 8 As shown, tray handles 14 are fixedly provided on both the front and rear sides of the tray 1. One of the tray handles 14 is provided with a detachable labor-saving component 2. The labor-saving component 2 includes a clamping plate 201, which is clipped onto the outer end of the tray handle 14.

[0046] A handle 202 is provided on the side of the clamping plate 201 away from the tray 1. Two telescopic rods 203 are provided between the handle 202 and the clamping plate 201, and the two ends of the telescopic rods 203 are fixedly connected to the handle 202 and the clamping plate 201 respectively.

[0047] The clutch itself weighs about 10kg, and with the weight of tray 1, operating tray 1 and the clutch rotation requires considerable force. Under normal circumstances, tray 1 can be manually rotated using tray handle 14. If this method is too strenuous, clamp 201 can be attached to the outer end of tray handle 14, and handle 202 can drive telescopic rod 203 and clamp 201 to rotate around central axis 12, thereby driving tray 1 and clutch rotation. This method of control increases the lever arm of the driving force, making it easier to control tray 1 rotation. Furthermore, it allows for control of the extension and retraction of telescopic rod 203, automatically adjusting the lever arm, making it more practical.

[0048] In order to alleviate the stress on the locking pin 9, such as Figure 1 , 3 As shown in Figures 6 and 7, two tension components 6 are provided below the tray 1. The two tension components 6 are arranged symmetrically front and back. Each tension component 6 includes a tension rope 601. 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 of the tray 1. The two hooks 602 are respectively hung on the two hanging rings 13.

[0049] The tension rope 601 is fixedly provided with an upper sleeve 606 at the end away from the tray 1, and the upper sleeve 606 is rotatably connected to a threaded sleeve 605 at the end away from the tray 1 via a bearing.

[0050] The tension assembly 6 also includes a lower sleeve 603, the bottom end of which is hinged to the top end of the base 5. A spring 607 is fixedly provided on the inner wall of the lower sleeve 603, and a central rod 608 is fixedly provided on one end of the spring 607.

[0051] The top end of the central rod 608 extends into the interior of the upper sleeve 606. The threaded sleeve 605 is threaded onto the outer end of the central rod 608. The outer end of the lower sleeve 603 is provided with a scale groove 604. One side of the scale groove 604 is marked with a scale on the outer end of the lower sleeve 603. The extension length of the spring 607 can be displayed through the scale.

[0052] Two tension components 6 are respectively installed 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. By rotating the threaded sleeve 605, the rotation of the threaded sleeve 605 under the action of the thread can control the central rod 608 to move upward into the sleeve 606, thereby driving the spring 607 to stretch. With the help of the elastic force of the spring 607, the tension rope 601 is pulled, making the tension rope 601 taut. This causes the tension component 6 to pull the tray 1 as a whole. The longer the spring 607 is stretched, the greater the tension force of the tension component 6 on the tray 1. Furthermore, the stretching length of the spring 607 can be accurately measured through the scale groove 604 and the scale, thereby accurately understanding the magnitude of the tension force of the tension component 6.

[0053] When the tray 1 is horizontal, the pulling force of the two pulling components 6 is equal. The two pull the tray 1 one after the other, and their pulling forces are balanced, which helps to keep the tray 1 horizontal. 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.

[0054] When tray 1 tilts forward, although locking spring pin 9 fixes tray 1, tray 1 still tends to rotate further forward under the weight of tray 1 and clutch. Therefore, locking spring pin 9 is under continuous force at this time. For this reason, the rear tension component 6 is connected to the hanging ring 13, while the front tension component 6 is idle. The rear tension component 6 pulls tray 1 backward to counteract the weight of tray 1 and clutch, reduce the force on locking spring pin 9, and prevent locking spring pin 9 from bending and deforming due to continuous force. When tray 1 tilts backward, the front tension component 6 is used to pull tray 1 forward, while the rear tension component 6 is idle. The principle is the same as when tilting forward.

[0055] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, 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.
