Description

Technical Field

[0001] This utility model relates to the field of gap and surface difference, and more specifically, to an adjustable auxiliary tool for controlling gap and surface difference in the assembly of vehicle body parts. Background Technology

[0002] Surface clearance difference refers to the difference in distance between two parallel surfaces. In automobile manufacturing, surface clearance difference is one of the important indicators of vehicle body appearance quality, directly affecting the vehicle's first impression and functionality. For example, surface clearance difference has a significant impact on wind noise suppression and waterproofing performance; inappropriate surface clearance difference may lead to unnecessary noise and water leakage problems during vehicle operation.

[0003] For example, Chinese patent CN 219565310 U discloses an auxiliary tool for controlling gaps and surface differences in the assembly of vehicle body parts, including a main body, a support, and a movable clamping component. The main body includes a first reference surface and a second reference surface. The first reference surface is used to contact the vehicle body. The support includes a first connector and a second connector that are vertically connected. The upper end of the first connector is connected to the first reference surface of the main body and includes a positioning surface. The rear end of the second connector is connected to the front end of the first connector, and the front end of the second connector protrudes from the front end of the main body. The second connector includes a supporting surface. The rear end of the vehicle body part contacts the positioning surface, and the lower end of the vehicle body part contacts the supporting surface. The movable clamping component is located above the second connector and has an installation gap between it and the support. The installation gap is set to match the thickness of the vehicle body part. The movable clamping component is used to fix the vehicle body part, which can effectively control the gaps and surface differences between the vehicle body part and the mating parts of the vehicle body, reduce the labor intensity of installation, and improve installation efficiency.

[0004] The aforementioned body component assembly clearance and surface difference control auxiliary tool is limited in its application when facing different clearance and surface differences because the main body and the supporting part are integrated. Therefore, we have made improvements and proposed an adjustable body component assembly clearance and surface difference control auxiliary tool. Utility Model Content

In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] like Figures 1-6 As shown, this embodiment proposes an adjustable body component assembly clearance surface difference control auxiliary tool, including a control body 1 and a control end 2 located on one side of the bottom of the control body 1. Insertion blocks 21 are fixed on both sides of the top of the control end 2. An insertion groove 22 adapted to the insertion block 21 is opened on one side of the bottom of the control body 1. It also includes a front fender 4 and a front door 5.

[0043] The plug-in block 21 is provided with a locking groove 23, and a locking structure 3 is provided at the bottom of the control body 1 near the plug-in groove 22. The locking structure 3 can lock the plug-in block 21 in the plug-in groove 22.

[0044] The locking structure 3 includes a guide groove 31 formed in the control body 1. Push plates 32 are slidably provided on both sides inside the guide groove 31. A locking post 33 is fixed on one side of the push plate 32 and the locking post 33 is adapted to the locking groove 23. The locking post 33 can be inserted into the locking groove 23 by sliding along the guide groove 31. The guide groove 31 can only make the two push plates 32 slide in the same straight line direction without shaking.

[0045] One end of the push plate 32 extends into the adjustment groove 34, and the adjustment groove 34 is connected to the guide groove 31. A connecting spring 35 is provided in the adjustment groove 34 for fixing to the push plates 32 at both ends. Under the action of the spring 35, the two push plates 32 can be moved away from each other in their natural state.

[0046] The top of the control terminal 2 is also fixed with a positioning block 24 between the two plug-in blocks 21, and the bottom of the control body 1 has a positioning groove 11 that is adapted to the positioning block 24.

[0047] The positioning block 24 has a support platform 240 on one side and a contact surface 241 on the other side.

[0048] A cavity 12 is provided in the middle of the control component 1, and the cavity 12 extends toward the control end 2 and eventually communicates with the outside.

[0049] A positioning plate 13 is slidably disposed in the cavity 12, and a fixing block 14 is slidably disposed inside the positioning plate 13. A lead screw 15 is movably mounted on the top of the fixing block 14 through a bearing, and the lead screw 15 is threadedly engaged with the fixing block 14. A guide rod 16 is slidably disposed on the inner side of the positioning plate 13 and fixed to the side wall of the cavity 12.

[0050] The other side of the control component 1 has adsorption holes, and an adsorption disk 17 is provided in the adsorption holes;

[0051] The above plan will be further described below with reference to specific working methods:

[0052] Specifically, when using this adjustable body component assembly gap surface difference control tool: the control component 1 is attached to the front door 5 by adsorption plate 17, and the contact surface 241 is made to fit with the side of the front door 5 facing the front fender 4. Then, the side of the front fender 4 to be installed is placed on the support platform 240 and pressed against its side wall. At this time, the gap surface difference between the front fender 4 and the front door 5 has been positioned by the control end 2. Then, the positioning plate 13 is moved so that the fixing block 14 on it moves to the outside of the cavity 12. The screw 15 is rotated so that it forms a threaded engagement with the fixing block 14. The fixing block 14, driven by the driving force, will slide down so that the bottom of the fixing block 14 abuts against the surface of the front fender 4, forming a clamping and positioning effect on the front fender 4. Then, the connecting component of the front fender 4 away from the front door 5 can be adjusted to connect it to the corresponding connecting area for fixation. Finally, the control component 1 can be slid out along the gap.

[0053] When dealing with different gap surface differences, the corresponding control end 2 can be selected and replaced on the control body 1. Specifically, the two push plates 32 in the sliding adjustment groove 34 are brought closer to each other. When the push plate 32 slides, the locking pin 33 on it will gradually disengage from the corresponding locking groove 23 and finally release the lock on the plug-in block 21. Then, the control end 2 can be pulled out to remove it. Then, the corresponding model of control end 2 is inserted into the corresponding plug-in groove 22 and positioning groove 11 through the plug-in block 21 and positioning block 24. Then, the push plate 32 is released, and the push plate 32 slides back to its original position through the reset action of the connecting spring 35. Finally, the locking pin 33 is inserted into the corresponding locking groove 23 to lock the replaced control end 2.

[0054] The main differences between different models of control terminal 2 are the thickness of the side and the thickness of the bottom. However, the plug-in block 21 and the positioning block 24 maintain the same model. The replacement of the control terminal 2 mentioned above only means that a more suitable model of control terminal 2 is selected within a certain gap surface difference range. It does not mean that control terminal 2 of any size can be used to meet the installation of all body parts.

[0055] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
