[0031] Inner pressing mechanism, when pressing, press fit on the side wall framework;

[0032] Outer pressing mechanism, when pressing, press fit on the side wall board;

[0033] Connecting piece 2, one end is connected with inner pressing mechanism, and the other end is connected with advancing mechanism 9;

[0034] Advancing mechanism 9, one end is assembled with the outer pressing mechanism, and the other end is slidably connected with the connecting piece 2, drives the outer pressing mechanism to move along the connecting piece 2, adjusts the pressing force between the inner pressing head 5 and the outer pressing head 6.

[0035] The utility model provides a kind of vehicle body side wall compression auxiliary tool, including clamp 1 and pressing plate 10.

[0036] As Figure 1 And Figure 2 Indicated, inner compression mechanism, outer compression mechanism and advancing mechanism 9 are assembled and connected into integrated structure by connecting piece 2, connecting piece 2 includes fixed rod 4 and sliding rod 3, fixed rod 4 and sliding rod 3 are mutually fixed or integrally formed, and constitute the structure mode of generally L type.The end of cross arm is assembled and fixed with inner compression mechanism, and the other end is fixed or integrally formed with sliding rod 3.

[0037] Inner compression mechanism includes inner compression head 5, and the compression surface of inner compression head 5 is circular, as inner compression head 5 is round cake structure, or in other words, inner compression head 5 is the plate structure with circular compression surface, as Figure 2 Indicated, in the embodiment, inner compression head 5 is rectangular plate structure with rounding processing at edge angle.When being compressed and fixed, the compression surface of inner compression head 5 is abutted with side wall framework, to avoid damage to side wall framework by compression force, the compression surface of inner compression head 5 requires to have certain area, and this area can be converted according to the compression force used to prevent side wall plate from sliding and the strength of side wall framework.In practical application, inner compression head 5 can be compressed at the position with large rigidity of side wall framework.

[0038] One side of inner compression head 5 is directly fixed or integrally formed with the end of fixed rod 4 cross arm, further, inner compression head 5 is connected with the end of cross arm through a segment of generally Z-shaped bending arm, so that the compression surface of inner compression head 5 protrudes from the top surface of cross arm (the surface of cross arm towards side wall framework in compression state) or is flush with the top surface of cross arm, to avoid interference of forearm when compressing, so that inner compression head 5 cannot be compressed on side wall framework.Or as Figure 1 Indicated, inner compression head 5 is integrally formed with fixed rod 4 cross arm, and the bottom surface of inner compression head 5 is flush with the bottom surface of cross arm.

[0039] Advancing mechanism 9 is connected with sliding rod 3 and can move horizontally along sliding rod 3.In the embodiment, advancing mechanism 9 is rod structure, and one end is provided with connecting hole, and the shape of connecting hole is same with the shape of sliding rod 3, and the size is similar.

[0040] Sliding rod 3 is inserted into the connecting hole of advancing mechanism 9, so that advancing mechanism 9 is connected with sliding rod 3 in sleeve structure, and advancing mechanism 9 can move along sliding rod 3 smoothly.

[0041] After sliding rod 3 and advancing mechanism 9 are assembled, the rod structure of advancing mechanism 9 is parallel with fixed rod 4, and the axis of sliding rod 3, advancing mechanism 9 and fixed rod 4 is coplanar.

[0042] The other end of the pushing mechanism 9 is connected to the external clamping mechanism, which drives the external clamping mechanism to move along the sliding rod 3 to adjust its position, thereby adjusting the distance between the pushing mechanism 9 and the fixed rod 4, that is, the distance between the clamping surface of the external clamping mechanism and the clamping surface of the internal clamping mechanism, thus improving the applicability of the clamp 1, which is suitable for vehicle models with different thicknesses, and is also suitable for clamping and fixing different positions and structural thicknesses of the side wall frame.

[0043] Furthermore, to prevent the propulsion mechanism 9 from rotating axially along the sliding rod 3, a limit structure is provided on the sliding rod 3, such as... Figure 1 As shown, the sliding rod 3 includes a cylinder with a truncated edge. A plate-like structure of equal length is fixed at the truncated edge. The width of the plate-like structure is equal to the length of the truncated edge. By setting the plate-like structure, the propulsion mechanism 9 is restricted from rotating around the axis of the sliding rod 3.

[0044] Furthermore, the sliding rod 3 is also provided with an axial limiting structure, which can limit the position of the propulsion mechanism 9 on the sliding rod 3. Once the position of the propulsion mechanism 9 is determined, the axial limiting structure limits the position of the propulsion mechanism 9 on the sliding rod 3, so that the connecting piece 2 and the propulsion mechanism 9 form a fixed structure. For example, multiple through holes are provided on the sliding rod 3, and a limiting pin is inserted into each side of the propulsion mechanism 9, or the two ends of the U-shaped limiting pin are inserted into the through holes on both sides of the propulsion mechanism 9, thus limiting the position of the propulsion mechanism 9 on the sliding rod 3.

[0045] Furthermore, such as Figure 2 As shown, a limiting post 11 is provided at the bottom of the sliding rod 3 to prevent the propulsion mechanism 9 from detaching from the sliding rod 3. The limiting post 11 is detachably connected to the sliding rod 3, making it easy to disassemble the propulsion mechanism 9 during maintenance.

[0046] The limiting structure and axial limiting structure can adopt any existing technology or any structure that can realize the limiting function in the future, without requirements or restrictions. The limiting structure includes, but is not limited to, the cylindrical fixing plate structure with cut edges as described above, and the axial limiting structure includes, but is not limited to, the through hole and limiting pin as described above.

[0047] The other end of the propulsion mechanism 9 is provided with a through hole, and the external clamping mechanism is fitted and connected to the propulsion mechanism 9 at the through hole. Furthermore, the inner wall of the through hole is provided with an internal thread, and the external clamping mechanism includes a screw 7 and an external clamping head 6. The screw 7 is threadedly connected to the through hole, that is, the propulsion mechanism 9 is threadedly connected to the internal clamping mechanism.

[0048] The outer clamping head 6 is fixed to one end of the screw 7, and the clamping surface is opposite to the clamping surface of the inner clamping head 5. Furthermore, the inner clamping head 5 and the outer clamping head 6 are axially opposite each other.

[0049] The outer pressing head 6 can be a conical frustum structure, the diameter of the top surface (small diameter end) of the conical frustum is greater than or equal to the diameter of the screw rod 7, and the diameter of the bottom surface (pressing surface) is greater than the diameter of the screw rod 7. Further, the pressing surface area of the outer pressing head 6 is greater than the pressing surface area of the inner pressing head 5. The outer pressing head 6 is pressed on the side wall panel, and a large-area outer pressing head 6 is used to avoid leaving marks on the side wall panel during clamping and fixing.

[0050] Further, as shown in Figure 2 the bottom (small diameter end) of the outer pressing head 6 is inserted or threadedly connected with the top (end towards the outer pressing head) of the screw rod 7, but for disassembly and assembly of the outer pressing head 6. Preferably, the outer pressing head 6 and the top of the screw rod 7 are connected by a lead screw, that is, the top of the screw rod 7 is provided with a mounting hole with internal threads, and the small diameter end of the outer pressing head 6 is provided with a lead screw, so that the outer pressing head 6 and the screw rod 7 form a lead screw connection, and rotating the screw rod 7 can realize the linear lifting of the outer pressing head 6, avoiding leaving rotating marks on the side wall panel.

[0051] The screw rod 7 is threadedly connected with the advancing mechanism 9, and after the position of the advancing mechanism 9 on the sliding rod 3 is defined by the axial limiting structure, the screw rod 7 is rotated to drive the inner pressing head 5 to rise and fall, thereby adjusting the distance between the inner pressing head 5 and the outer pressing head 6, and in the clamping state, the clamping force of the clamp 1 on the side wall panel and the side wall framework is adjusted.

[0052] Preferably, a pad such as a nylon or rubber pad is attached to the pressing surface of the outer pressing head 6, so that the outer pressing head 6 elastically contacts the outer wall panel, further avoiding leaving marks on the outer wall panel.

[0053] In order to rotate the screw rod 7, a rotating rod 8 is provided at the other end of the screw rod 7 (the end not provided with the outer pressing head 6), the rotating rod 8 is assembled and connected with the screw rod 7, and pushing the rotating rod 8 can drive the screw rod 7 to rotate.

[0054] As shown in Figure 1 , a through hole is provided at the end of the screw rod 7, and the rotating rod 8 is inserted into the through hole. Further, the diameters of the two end faces of the rotating rod 8 are different, the diameter of the large diameter end is greater than the diameter of the through hole, and the diameter of the small diameter end is less than or equal to the diameter of the through hole, and preferably, the diameter of the small diameter end is less than the diameter of the through hole.

[0055] Still further, the rotating rod 8 can be a tapered rod, the diameter of the rotating rod 8 linearly decreases from the large diameter end to the small diameter end; or the main body structure of the rotating rod 8 is a circular rod with uniform diameter, and a conical frustum is provided at one end, and the diameter of the small diameter end of the conical frustum is the same as the diameter of the circular rod.

[0056] In use, the small-diameter end (round rod end) of the rotating rod 8 is inserted into the through hole, and as the diameter of the rotating rod 8 increases, the rotating rod 8 cannot be continuously inserted when the diameter of the rotating rod 8 is equal to the diameter of the through hole, so that the relative position of the rotating rod 8 and the screw rod 7 is defined by the large-diameter end, and the rotating rod 8 is prevented from falling off the screw rod 7 in use. The length of the rotating rod 8 is less than the length of the rod body of the advancing mechanism 9 (excluding the part of the through hole at both ends), so that the rotating rod 8 is prevented from interfering with the sliding rod 3 when the rotating rod 8 is pushed. In actual application, other arbitrary structures can also be used to detachably connect the rotating rod 8 and the screw rod 7, and the anti-falling structure is arranged on the rotating rod 8.

[0057] The vehicle body side wall pressing auxiliary tool also comprises a pressing plate 10, in this embodiment, as shown in the drawings, the pressing plate 10 is made of high-strength and high-flatness aluminum pressing plate 10, the pressing surface of the aluminum pressing plate 10 is similar to the shape of the outer surface of the side wall plate to be pressed, and the aluminum pressing plate 10 is arranged between the outer pressing head 6 and the side wall plate during clamping and fixing. Figure 3

[0058] Further, the aluminum pressing plate 10 has a certain length and can be used for clamping operation of multiple clamps 1 at the same time, so that the clamping force of the multiple clamps 1 can be evenly distributed to the side wall, thereby ensuring that the side wall plate always maintains flatness during the curing process and avoiding deformation.

[0059] During the vehicle body assembly process, after the side wall plate is bonded with the vehicle body side wall framework, the vehicle body side wall pressing auxiliary tool is used to clamp and fix the side wall plate and the side wall framework at positions such as the top, bottom, window and door of the vehicle body.

[0060] For example, the specific use method of the auxiliary tool is introduced by taking the bottom position of the vehicle body side wall as an example. According to the length of the aluminum pressing plate 10, the number of clamps 1 to be used is evenly distributed, and according to the structural features of the side wall framework at the clamping position of each clamp 1, the relative position of the advancing mechanism 9 on the sliding rod 3 is adjusted, and after adjustment, the specific position of the advancing mechanism 9 is defined by the axial limiting structure, thereby preliminarily adjusting the relative distance between the inner pressing head 5 and the outer pressing head 6.

[0061] The aluminum pressing plate 10 is attached to the side wall plate to be pressed, and the inner pressing mechanism and the outer pressing mechanism move from bottom to top, so that the aluminum pressing plate 10 and the side wall plate and the side wall framework are inserted into the space between the two pressing heads, so that the inner pressing head 5 is pressed on the side wall framework, and the outer pressing head 6 is preliminarily pressed on the aluminum pressing plate 10.

[0062] When the bottom of the side wall plate and the side wall plate is in contact with the sliding rod 3 between the two pressing heads, the clamp 1 is stopped, so that the sliding rod 3 plays a certain supporting role on the side wall plate and the side wall framework.

[0063] ​The rotating rod 8 outer pressing mechanism is assembled and connected in advance, the rotating rod 8 is pushed, the outer pressing head 6 is driven to move towards the inner pressing head 5 direction, the distance between the outer pressing head and the inner pressing head 5 is fine-adjusted, that is, the pressing force of the two pressing heads to the side wall plate and the side wall framework is adjusted. By setting the aluminum pressing plate 10, the rotating outer pressing head 6 is prevented from scratching the surface of the side wall plate;

[0064] When the outer pressing head 6 cannot continue to advance or the force for pushing the rotating rod 8 is large, the rotation is stopped, and it is considered that the pressing force is too large. When to stop can be determined according to the experience of on-site operators, or a torsion sensor can be arranged on the rotating rod 8, and when the torsion reaches a preset value, the adjustment is stopped.

[0065] According to the setting, the clamp 1 is pressed with the aluminum pressing plate 10, the side wall plate and the side wall framework respectively, so that the clamp 1 clamps and fixes the side wall plate and the side wall framework.

[0066] Correspondingly, the clamp 1 and the aluminum pressing plate 10 are clamped and fixed at the edge part of the side wall plate and the side wall framework, the side wall plate is clamped and fixed to prevent the side wall plate from sliding downward, and under the action of the high-strength and high-flatness aluminum pressing plate 10 and the clamp 1, the side wall plate can always maintain flatness during the curing process, and deformation is avoided.

[0067] Compared with the prior art, the vehicle body side wall pressing auxiliary tool has the following technical advantages:

[0068] The utility model discloses a high-strength and high-flatness aluminum pressing plate and a clamp are combined, the design structure is reasonable, and efficient and convenient to use can be applicable to different vehicle models and various occasions side wall plate bonding fixed use, the utility model discloses a clamp and fix the side wall plate simultaneously, under the action of the high-strength and high-flatness aluminum pressing plate and the clamp, the side wall plate can always maintain flatness during the curing process, and deformation is avoided.

[0069] As described above, in combination with the given scheme content, similar technical schemes can be derived. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the utility model still belong to the range of the utility model technical scheme.
