Description

Technical Field

[0001] The utility model relates to the technical field of installation auxiliary tools, in particular to a shock-absorbing spring bolt auxiliary device. Background Art

[0002] In automobile assembly, the front shock absorber assembly process is as follows: 1. Confirm that the specifications of the front steering knuckle are correct; 2. Install the front shock absorber spring on the steering knuckle. 3. Install two front shock absorber spring bolts (install into the front shock absorber and steering knuckle mounting holes). 4. Pre-install two nuts on the front shock absorber spring bolts. 5. Use a simple clamp to assist the electric wrench to tighten the bolts. The simple clamps currently used are mostly single-bolt auxiliary tools. In the actual installation process, two people are required to use this single-bolt auxiliary tool to set it on the nut, relying on manpower to ensure that the nut does not move during the screwing process. However, in practice, the shock absorber spring bolts are tightened with an electric wrench, and the tightening torque is usually large, usually 142.1~161.7Nm. During the screwing process, the clamp is easy to detach from the nut, causing problems such as bolt slippage and nut corner collapse. At this time, excessive labor and material costs will be generated, and the installation efficiency is relatively low. Utility Model Content

Specific embodiments

[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope protected by the present utility model.

[0022] Specific embodiments of the present utility model provide a shock-absorbing spring bolt auxiliary device. Combining with the attached Figure 1 -attached Figure 4 As shown, it mainly includes an installation frame 1, a nut locking part 2 and a part locking part 3;

[0023] Among them, the number of nut locking parts 2 is at least two and they are arranged on the mounting bracket 1. The nut locking parts 2 are used to lock nuts. At least two nut locking parts 2 can be set on two adjacent nuts. Then, the mounting bracket is used to limit the two nut locking parts 2, so that the mounting bracket will not rotate around the nut locking parts 2, enabling the two locking nuts to lock each other. One end of the part locking part 3 is slidably connected to the mounting bracket 1, and the other end has a locking head 4 for connecting to the part. In actual use, first, at least two nut locking parts 2 act on at least two nuts, and then the part is locked to the part through the part locking part 3, thus no longer requiring auxiliary workers to hold by hand, thereby reducing labor costs. Moreover, the setting of the part locking part 3 can prevent the problem of nut damage caused by the shock-absorbing spring bolt auxiliary device falling off the nut, thus saving material costs. At the same time, the method of locking two nuts improves work efficiency.

[0024] In a specific embodiment of the present application, the nut locking part 2 includes a sleeve 5 and a hinged end 6 connected to the sleeve 5. One end of the sleeve 5 has an inner hole adapted to the nut. The other end of the sleeve 5 is connected to the hinged end 6. The sleeves 5 on the two nut locking parts 2 are arranged side by side in the same direction, so that the two nuts can be locked face to face. The hinged end 6 passes through the mounting bracket 1 for hinging, so that the sleeve 5 can be hinged relative to the mounting bracket 1, which is more convenient when connecting to the nut. A tightening part 7 is arranged on the hinged end 6. When two adjacent nut locking parts 2 rotate in the same direction, the two tightening parts 7 abut against each other. The forces applied to the bolt during the bolt tightening process are in the same direction. Therefore, the tendency forces in the rotation directions of the two nut locking parts 2 are also in the same direction. At this time, the further rotation of the two nut locking parts 2 is restricted by the abutting of the two tightening parts 7, thus playing a locking role. As shown in the appendix Figure 4 As shown, the two tightening parts 7 are respectively arranged on both sides of the two hinged ends 6 and extend towards each other. In this way, when the two nut locking parts 2 rotate in the same direction, for example, when both rotate counterclockwise, the rotation of the nut locking part 2 can be restricted under the tightening action of the tightening part 7 to achieve the locking effect. Of course, the setting directions of the two tightening parts 7 can be set according to the actual tightening direction of the bolt, ensuring that the tightening part 7 can restrict the rotation of the nut locking part 2 under the tightening action in the bolt tightening direction.

[0025] In some embodiments, it further includes an unlocking mechanism 8 rotatably arranged on the mounting frame 1. One end of the unlocking mechanism 8 has an unlocking body 9 and is located between two adjacent pressing parts 7. It should be noted that during the tightening process of the two bolts, due to the hinged assembly method of the nut tightening part 2 and the angle change of the two nut tightening parts 2 during the screwing process, after the screwing is completed, the shock-absorbing spring bolt auxiliary device will be locked on the two nuts and is not easy to disassemble. Therefore, the unlocking mechanism 8 in this application is provided. By slightly adjusting the position of the pressing part 7 through the unlocking mechanism 8, the pressing can be loosened in reverse, so that the shock-absorbing spring bolt auxiliary device can be disassembled more conveniently.

[0026] In some embodiments, in combination with the attached Figure 4 , where the unlocking body 9 can be a strip-shaped block. The middle of the unlocking body 9 is connected to the rocker 10. The rocking of the rocker 10 can drive the unlocking body 9 to rotate, and then push the pressing parts 7 on both sides to act. The two end faces of the unlocking body 9 are arc surfaces 11 and are smoothly connected to the planes 12 on both sides of the unlocking body 9. In this way, the pressing part 7 can slide smoothly on the unlocking body 9. When the two nut tightening parts 2 rotate in the same direction, the two pressing parts 7 abut against the planes 12 on both sides of the unlocking body 9. This application adopts the technical solution of driving the unlocking body 9 to rotate by the rocker 10 to unlock, so as to achieve the expected unlocking effect.

[0027] In some embodiments, the mounting frame 1 includes two parallel plate bodies 13 and a connecting piece 14 connected between the two plate bodies 13. The connecting piece 14 can be a bolt, and there can be four bolts respectively arranged at the four corners of the plate body. An installation space 15 is formed between the two plate bodies 13. The hinged end 6 passes through one of the plate bodies 13 and extends into the installation space 15 to be connected to the pressing part 7, and the rocker 10 passes through the other plate body 13 and extends into the installation space 15 to be connected to the unlocking body 9. In this way, the pressing part 7, the unlocking body 9 and other movable parts are arranged in the installation space 15, reducing potential safety hazards.

[0028] In some embodiments, a bearing 16 is arranged on the pressing part 7. The bearing 16 can abut against the plane 12. By arranging the bearing 16, a rolling contact method is formed between the pressing part 7 and the unlocking body 9, making the contact smoother.

[0029] In some embodiments, in combination with the attached Figure 2 As shown, the part locking part 3 is L-shaped. One end of the part locking part 3 is slidably connected to the mounting frame 1. A sliding groove is opened on the mounting frame 1. One end of the part locking part 3 extends into the sliding groove for relative sliding. The other end of the part locking part 3 is a locking head 4. The locking head 4 can be a protrusion facing the direction of the shock-absorbing spring bolt auxiliary device. The part locking part 3 can move towards and away from the nut locking part 2. By hooking the part with the locking head 4, the fixing effect on the shock-absorbing spring bolt auxiliary device is achieved.
