[0002] An interior trim panel needs to be provided on the inner surface of an automobile body to facilitate the tidiness inside the body. An interior door panel also needs to be provided on the inner surface of an automobile door. The interior door panel not only plays a decorative role, but also can hide wiring harnesses, improve the sound insulation effect, and has a buffering effect in the event of a collision.

[0003] The interior door panel is a plastic part and is also composed of multiple plastic parts welded by hot riveting. There are mainly two welding methods in the current technology. One is to use an intelligent hot riveting welding machine, which is an integrated intelligent device that can automatically perform feeding, clamping, welding, and blanking. Due to the large cost investment, this welding method is mainly applied to large manufacturing factories; the other is to use a hand-held welding machine for manual welding. This welding method has low cost and is easy to operate. However, when welding, pressure needs to be applied through a hot riveting machine to make the interior parts fit tightly with the interior door panel. However, the inner door panel will be concave and deformed after being subjected to pressure, which will affect the welding quality. Therefore, an auxiliary tooling for welding automobile door panels needs to be designed. Content of the Utility Model

[0027] The following will explain in detail the specific implementation manners of the present utility model with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0028] In the present utility model, unless otherwise stated, the directional terms such as "upper, lower, inner, outer" included in the terms only represent the orientation of the terms in the normal use state, or the common names understood by those skilled in the art, and should not be regarded as a limitation to the terms.

[0029] As Figures 1-5 shown, an auxiliary tool for welding automobile door panels includes: a horizontal bottom plate 2 with a plurality of support feet 1 at the bottom mounting part, a horizontal top plate 4 assembled on the top of the bottom plate 2 through a plurality of vertical support columns 3, and at least one set of support units detachably assembled on the bottom plate 2. A relief through groove is provided through the middle of the top plate 4, and a plurality of parallel first strip-shaped through grooves 5 are provided through the bottom plate 2. A plurality of positioning fixtures 6 each formed with a positioning stepped groove are detachably assembled on the top plate 4;

[0030] The support unit includes a support arm 7 that can contact the upper surface of the bottom plate 2, a connection disk 8 fixedly installed on the upper surface of the support arm 7, at least one set of support mechanisms detachably assembled on the connection disk 8 and capable of moving circumferentially around the connection disk 8 to adjust the position, and at least one first mounting bolt 9 passing through the corresponding first strip-shaped through groove 5 and threadedly connected to the support arm 7.

[0031] When welding is required, place the door panel on several positioning jigs 6. The edge of the door panel will be stuck into the positioning step groove. Clip another plastic part onto the door panel. Since there are protruding welding anchor points on the door panel, the corresponding through holes of the plastic part can be stuck onto the door panel. The support unit can support the door panel from below, and the support mechanism will be directly below the welding anchor point to support the welding anchor point. The operator will hold a hot riveting machine to melt the welding anchor point. When welding, downward force needs to be applied to make the plastic part fit tightly with the door panel. Since the support mechanism supports the door panel from below, the door panel will not be concave due to the force, and the tightness of the fit between the plastic part and the door panel can also be improved.

[0032] The welding positions on the door panel are different for each process. According to the actual use situation, the corresponding number of support units can be installed on the bottom plate 2, and the positions of the support units can be adjusted accordingly. The position of the support mechanism on the connecting plate 8 can also be adjusted, and the number of support mechanisms on the connecting plate 8 can also be adjusted, with strong applicability. When welding door panels of different models, in addition to adjusting the number of support units and the number of support mechanisms on the corresponding connecting plate 8, it is also necessary to replace the positioning jigs 6 on the top plate 4 with the positioning jigs 6 corresponding to the door panel.

[0033] The support mechanism includes an adjusting arm 10 that is detachably assembled on the connecting plate 8 through an installation member and is located above the connecting plate 8 with adjustable height between it and the connecting plate 8, and at least one sliding sleeve 11 that is detachably and slidably installed on the adjusting arm 10. At least one first locking bolt 12 whose end can abut against the adjusting arm 10 is threadedly connected to the sliding sleeve 11. The top of the sliding sleeve 11 is fixedly connected with a vertical first threaded rod 13. The top of the first threaded rod 13 is threadedly connected with a support member 15. A rubber pad 14 is fixedly arranged on the top of the support member 15. The length direction of the adjusting arm 10 is the same as the radial direction corresponding to the connecting plate 8.

[0034] The top of the support member 15 is in contact with the lower surface of the door panel. When the welding anchor points are dense, in addition to assembling multiple groups of support mechanisms on the connecting plate 8 at the same time, multiple support members 15 can also be assembled on the same support mechanism.

[0035] Loosen the first locking bolt 12, and the sliding sleeve 11 can be removed from the end of the adjusting arm 10, and the sliding sleeve 11 can also be slidably installed on the adjusting arm 10 from the end of the adjusting arm 10. Tighten the first locking bolt 12, and the sliding sleeve 11 can be fixed on the adjusting arm 10.

[0036] The height of the adjusting arm 10 can be adjusted through the installation member, so as to support different height parts of the door panel.

[0037] The support member 15 includes a threaded sleeve threadedly mounted on the top of the first threaded rod 13 and a support plate fixedly mounted on the top of the first threaded rod 13. A first locking nut 16 is threadedly sleeved on the first threaded rod 13 and can abut against the lower end of the threaded sleeve.

[0038] The support member 15 can be replaced according to the actual usage situation. Since the door panel is of an irregular shape, a support member 15 with a horizontal, inclined or special-shaped support plate can be selected. When the direction of the support plate needs to be adjusted, since the threaded sleeve is threadedly mounted on the first threaded rod 13, the threaded sleeve can rotate. After the first locking nut 16 abuts against the threaded sleeve, it can prevent the threaded sleeve from rotating.

[0039] The mounting member includes a mounting frame 17 detachably connected to the connecting disc 8, a guide rod 18 fixedly connected to the lower surface of the adjusting arm 10 and vertically slidably connected to the mounting frame 17, a threaded seat 19 fixedly mounted on the mounting frame 17, a vertical adjusting bolt 20 threadedly passing through the threaded seat 19 and having its upper end pivotally connected to the adjusting arm 10, a vertical second threaded rod 21 fixedly connected to the adjusting arm 10 and having its lower end passing through the mounting frame 17, and a second locking nut 22 threadedly mounted on the second threaded rod 21 and capable of contacting the lower surface of the mounting frame 17.

[0040] The second threaded rod 21 is located on the side of the guide rod 18 away from the axis of the connecting disc 8, the adjusting bolt 20 is located on the side of the guide rod 18 close to the axis of the connecting disc 8, and an avoidance notch for avoiding the adjusting bolt 20, the guide rod 18 and the second threaded rod 21 is provided at the bottom of the sliding sleeve 11.

[0041] When the height of the adjusting arm 10 needs to be adjusted, loosen the second locking nut 22 to increase the distance between the second locking nut 22 and the mounting frame 17, and then rotate the adjusting bolt 20, which can drive the adjusting arm 10 to move vertically and drive the guide rod 18 to slide vertically on the mounting frame 17. After the height of the adjusting arm 10 is adjusted, tighten the second locking nut 22 so that the second locking nut 22 abuts against the mounting frame 17.

[0042] When the operator holds the hot riveting machine for welding, the support member 15 will be subjected to a downward pressure. The functions of the second threaded rod 21 and the second locking nut 22 are to limit the distance between the end of the adjusting arm 10 away from the connecting disc 8 and the connecting disc 8, so as to avoid the degree of downward inclination of the end of the adjusting arm 10 close to the connecting disc 8 due to the force.

[0043] The mounting frame 17 includes a first connecting arm 23 in contact with the upper surface of the connecting disc 8, a second connecting arm 24 arranged in parallel with the first connecting arm 23 and located below the connecting disc 8, and a connecting body 25 fixedly connected to the ends of the first connecting arm 23 and the second connecting arm 24 away from the axis of the connecting disc 8.

[0044] The upper surface of the connection plate 8 is recessed with at least two concentric annular grooves 26, and a plurality of positioning bumps 27 that protrude from the first connection arm 23 and are slidably inserted into the corresponding annular grooves 26 one by one are provided. At least one third locking bolt 28 whose end can abut against the bottom of the connection plate 8 is threadedly connected to the second connection arm 24.

[0045] When it is necessary to install the connection mechanism on the connection plate 8, first loosen the third locking bolt 28 so that the end of the third locking bolt 28 moves away from the first connection arm 23, move the first connection arm 23 and the second connection arm 24 to both sides of the connection plate 8 respectively, slidably insert the positioning bumps 27 into the corresponding annular grooves 26, and then tighten the third locking bolt 28 so that the end of the third locking bolt 28 tightly abuts against the bottom of the connection plate 8; when the third locking bolt 28 is loosened, the mounting bracket 17 can rotate around the axis of the connection plate 8.

[0046] When it is necessary to remove the mounting mechanism on the connection plate 8, loosen the third locking bolt 28, the first connection arm 23 and the second connection arm 24 can move upward, drive the positioning bumps 27 to move out of the annular grooves 26, and then horizontally move the mounting bracket 17, and the mounting bracket 17 can be removed.

[0047] A first support plate 29 that is fixedly installed at the bottom of the support arm 7 and fits with the bottom plate 2 is provided. A second support plate 30 that can fit with the lower surface of the bottom plate 2 is sleeved on the first mounting bolt 9. Anti-slip lines are provided on one side of the first support plate 29 and the second support plate 30 that fit with the bottom plate 2.

[0048] The first support plate 29 and the second support plate 30 can increase the contact area with the bottom plate 2, thereby improving the installation stability of the support unit.

[0049] A plurality of second strip-shaped through grooves 31 that are distributed around the avoidance through groove are provided through the top plate 4. Each positioning tool 6 is assembled on the top plate 4 through a plurality of second mounting bolts that pass through the corresponding second strip-shaped through grooves 31. A countersunk through hole that matches the second mounting bolt is provided on the positioning tool 6.

[0050] When it is necessary to weld door panels of different models, loosen and remove the second mounting bolts, and the positioning tool 6 can be removed. Then assemble the corresponding positioning tool 6 on the top plate 4. The second strip-shaped through groove 31 can increase the installation range of the positioning tool 6, so that the positioning tool 6 can be installed at different positions.
