[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. The components of the embodiments of this application usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents the selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative efforts belong to the scope of protection of this application.

[0033] After the inner surfaces of the four doors of the vehicle (the two side doors of the front vehicle and the two side doors of the rear vehicle) are sprayed, the vehicle body needs to be transferred to other production lines for the next operation. During the transfer of the vehicle body, auxiliary equipment is required to ensure that all four doors are in a closed state to prevent the doors from opening and causing scratches, collisions, etc., thereby affecting the painting quality. Existing auxiliary door-closing equipment either damages the paint on the inner surface of the door or has a complex installation and positioning and low installation efficiency.

[0034] The vehicle body automatic spraying door closing auxiliary tooling of this application respectively installs a first clamping structure 1 and a second clamping structure 2 on the inner body of the vehicle and the inner surface of the door, avoiding the first clamping structure 1 directly contacting the inner surface of the door, effectively preventing the first clamping structure 1 from damaging the paint on the inner surface of the door. In addition, the first clamping structure 1 and the second clamping structure 2 are magnetically coupled, and the first clamping structure 1 is fixedly installed on the inner body of the vehicle by a three-point positioning method, which can achieve the quick installation of the first clamping structure 1 in place and the quick cooperation of the first clamping structure 1 and the second clamping structure 2 in place.

[0035] A vehicle body automatic spraying door closing auxiliary tooling, comprising: a first clamping structure 1 and a second clamping structure 2. The first clamping structure 1 is used for clamping and installing on the inner body of the vehicle. The first clamping structure 1 includes a first clamping rod 11, a second clamping rod 12, and a magnetic attraction rod 13. At the upper and lower ends of the first clamping rod 11, there are respectively provided clamping openings 1121 for clamping on the side edge of the inner body of the vehicle. The second clamping rod 12 is connected to the first clamping rod 11 and is used for plug-in cooperation with the side surface of the inner body of the vehicle. The magnetic attraction rod 13 is connected to the first clamping rod 11 and / or the second clamping rod 12, and at least part of the magnetic attraction rod 13 has magnetism. The second clamping structure 2 is used for clamping and installing on the inner surface of the door, and at least part of the second clamping structure 2 has magnetism. The magnetism of the second clamping structure 2 is opposite to the magnetic part of the magnetic attraction rod 13 to magnetically couple with the magnetic attraction rod 13.

[0036] Further, as Figure 1 and Figure 2 shown, the first clamping rod 11 can be a straight rod or a curved rod, and both ends of the first clamping rod 11 are on the same side, that is, the side facing the inner side of the vehicle body (the inner side of the vehicle body can be the position where the door is hinged to the vehicle body), so as to facilitate grooving on the sides of both ends of the first clamping rod 11. After grooving at both ends of the first clamping rod 11, two clamping openings 1121 are formed. The first clamping rod 11 is preliminarily positioned on the side of the inner vehicle body through the two clamping openings 1121.

[0037] The second clamping rod 12 is welded to the first clamping rod 11. When the first clamping rod 11 is preliminarily positioned through the two clamping openings 1121, the second clamping rod 12 can be inserted into the corresponding side of the inner vehicle body side, so as to realize the three-point positioning installation of the first clamping rod 11 and the second clamping rod 12, without repeatedly adjusting the positions of the first clamping rod 11 or the second clamping rod 12, thereby improving the installation efficiency.

[0038] The magnetic attraction rod 13 can be fixedly installed on the first clamping rod 11, the second clamping rod 12 or the connecting part between the first clamping rod 11 and the second clamping rod 12. The magnetic attraction rod 13 can have magnetism as a whole or locally. When the magnetic attraction rod has magnetism locally, when the magnetic attraction rod is magnetically matched with the second clamping structure 2, the magnetic part of the magnetic attraction rod 13 is arranged opposite to the second clamping structure, so as to be magnetically matched with the second clamping structure.

[0039] The second clamping structure 2 is fixedly installed on the inner surface of the door, and the installation position needs to correspond to the position of the magnetic attraction rod 13. The second clamping structure 2 can have magnetism as a whole or locally. When the second clamping structure 2 has magnetism locally, when the second clamping structure 2 is magnetically matched with the magnetic attraction rod 13, the magnetic part of the second clamping structure 2 is opposite to the magnetic part of the magnetic attraction rod 13. When the door is closed, the magnetic part of the second clamping structure 2 needs to be opposite to the magnetic part of the magnetic attraction rod 13, so as to realize the magnetic attraction cooperation between the second clamping structure 2 and the magnetic attraction rod 13 and realize the closing of the door. And the magnetic force between the two needs to be appropriate, so as to avoid the door not being closed tightly or the door opening halfway due to too small magnetic force, or avoid the separation between the second clamping structure 2 and the magnetic attraction rod 13 being difficult to achieve due to too large magnetic force.

[0040] Further, the second clamping rod 12 is a curved rod, one end of the second clamping rod 12 is welded to the first clamping rod 11, the middle part of the second clamping rod 12 is spirally wound along a spiral line to form an elastic part 121, and the side of one end of the second clamping rod 12 is also used for clamping and pressing cooperation with the inner side of the vehicle body.

[0041] The second clamping rod 12 is set as a curved rod, which can reduce the space occupied by the second clamping rod 12. And the middle part of the second clamping rod 12 is wound and processed along a spiral line to form an elastic part 121 similar to a spring. When the first clamping rod 11 and the second clamping rod 12 achieve three-point positioning, the elastic part generates deformation to press the second clamping rod 12 against the side surface of the inner vehicle body, preventing the first clamping structure 1 from falling off the side surface of the inner vehicle body.

[0042] Further, a plugging and pressing part 123 is arranged on the side surface of one end of the second clamping rod 12, and the end of the pressing part 123 is right in the mounting hole on the side surface of the inner vehicle body, so that the pressing part 123 is pressed into the side surface of the vehicle body under the pressure of the elastic part 122.

[0043] The whole pressing part 123 can be in a shape matching the shape of the first mounting hole on the side surface of the inner vehicle body, such as cylindrical or prismatic, and can be welded or integrally formed with the side surface of one end of the second clamping rod 12. During three-point positioning, by adjusting the positions of the two bayonets 1121 mounted on the side of the inner vehicle body up and down, the end of the pressing part 123 is aligned with the first mounting groove, and then the pressing part 123 is pressed into the first mounting groove by the elastic part 121, making the overall positioning steps simple and easy to operate.

[0044] Further, the other end of the second clamping rod 12 extends parallel to the side surface of the inner vehicle body, thus forming a handle 122 for deforming the elastic part 121.

[0045] The other end of the second clamping rod 12 is in a straight rod shape, and this end extends along parallel to the inner side surface of the inner vehicle body to form a handle 122. The handle 122 is integrally connected with the elastic part 121. By swinging the handle 122, the elastic part 121 generates deformation, so that the pressing part 123 is pressed into the first mounting hole on the side surface of the vehicle body.

[0046] Further, the first clamping rod 11 includes: a first connecting rod body 111 and two clamping blocks 112. The two ends of the first connecting rod body 111 extend parallel to the side surface of the inner vehicle body, and the two clamping blocks 112 are respectively fixedly installed at the two ends of the first connecting rod body 111. And the bayonet 1121 of each clamping block 112 is clamped on the side of the inner vehicle body. The end of the second clamping rod 12 is welded to the middle part of the first clamping rod 11.

[0047] The two clamping blocks 112 are respectively welded to the two ends of the same side surface of the first connecting rod body 111. Each clamping block 112 can be square or cuboid, and bayonets 1121 are arranged on the same side surface of the two clamping blocks 112. Each bayonet 1121 is in the shape of a dovetail groove, that is, the opening of the bayonet 1121 is large and the bottom end is small. Even when the thickness of the side surface of the inner vehicle body clamped by the bayonet 1121 is different, preliminary clamping can be achieved, and the clamping block 112 will not be clamped too loose or too tight.

[0048] Further, the magnetic attraction rod 13 includes a connecting rod 131 and a magnetic member 132. One end of the connecting rod 131 is fixedly connected to the first connecting rod body 111, and the other end of the connecting rod 131 is detachably and fixedly connected to the magnetic member 132.

[0049] The connecting rod 131 can be a straight short rod and one end is welded to the middle of the first clamping rod 11. The magnetic member 132 is connected to the first clamping rod 11 through the connecting rod 131, so as to realize the support for the magnetic member 132.

[0050] Further, the magnetic member 132 includes a magnetic head 1321 and a threaded rod 1322. At least part of the axial side wall of the threaded rod 1322 is provided with an external thread. The other end of the connecting rod 131 is provided with a threaded connection head 1323, and a threaded hole is arranged inside the threaded connection head 1323, and then it is threadedly connected with the threaded rod 1322.

[0051] The magnetic head 1321 is integrally disc-shaped and has magnetism. The threaded rod 1322 is welded to the magnetic head 1321. By rotating the magnetic head 1321, the distance between the magnetic head 1321 and the inner surface of the car door can be changed, which is beneficial to the magnetic attraction cooperation between the magnetic head 1321 and the second clamping structure 2.

[0052] Further, as Figures 3 to 5 shown, the second clamping structure 2 includes a clamping head 21 and a magnetic plate 22. One end of the clamping head 21 is used for plugging into the inner surface of the car door, the other end of the clamping head 21 is fixedly connected to the magnetic plate 22, and the plate surface of the magnetic plate 22 faces the magnetic end surface of the magnetic head 1321.

[0053] The clamping head 21 can be integrally disc-shaped, and a clamping groove 211 is arranged on the side surface of the clamping head 21, so that the clamping head 21 is clamped on the side of the second mounting hole on the inner surface of the car door. The plate surface of the magnetic plate 22 is slightly larger than the area of the end surface of the magnetic head 1321. After the car door is closed, the plate surface of the magnetic plate 22 faces the end surface of the magnetic head 1321, so as to realize the magnetic attraction cooperation between the two.

[0054] Further, the magnetic head 1321 and the magnetic plate 22 are permanent magnets or electromagnets, and the magnetisms between the magnetic head 1321 and the magnetic plate 22 need to be opposite.

[0055] It should be noted that the above-mentioned first mounting hole and second mounting hole are both fixed structures on the car door, which are not shown in the figure. The pressing part 123 in the present application realizes the secondary positioning of the first clamping structure 1 through the plugging cooperation with the first mounting hole. The clamping head 21 extends into the second mounting hole, and the clamping head 21 is clamped on the second mounting hole through the clamping groove 211, so as to realize the fixed installation of the second clamping structure.

[0056] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all embodiments. The components of the embodiments of the present application described and illustrated in the drawings here can generally be arranged and designed in various different configurations.
