example 1:

as shown in fig. 1 and 5, reference numeral 23 denotes a side body outer panel 23 of an automobile body, and reference numeral 24 denotes a screw attachment hole to which an attachment screw is fastened in a door lock device.

The inner door plate 3 and the door lock reinforcing plate 2 are processed into inwards concave taper holes through the positions of mounting screws 4 by a stamping process, the inner door plate 3 and the door lock reinforcing plate 2 are welded and connected, and a door lock is connected to the inner door plate 3 through the mounting screws 4 in a threaded mode. The nut surface of the mounting screw 4 is flush with the door inner panel 3, and the lower bottom surface of the nut protrudes downward to form a spherical crown shape. The joint area of the lower bottom surface of the screw cap and the tapered hole is larger. The tapered hole of the door inner panel 3 is designed to interfere with the door lock in advance. The pre-interference is about 0.4mm-0.8 mm. At the door lock mounting blade design position, the portion where the door inner panel 3 interferes is pushed out upward. The outer surface of the inner car door plate 3 is covered and fixedly connected with a side wall outer plate. The side wall outer plate and the door inner plate 3 are approximately parallel, and a sealing strip 5 is arranged at one bending position. The sealing strip 5 can pass through the position of the mounting screw 4, so that the distance in the Y direction of the automobile is reduced. The weather strip 5 also has an extending lip 10, and the extending lip 10 abuts the door inner panel 3. The washer 11 is connected between the mounting screw 4 and the door inner panel 3. There is still a certain amount of clearance between the nuts of the mounting screws 4, the door inner panel 3 and the mounting position of the door lock, and the filler blocks 12 on the periphery of the tapered holes fill these clearances.

As shown in fig. 2 and 3, in the clamping tool, the threaded rod 16 passes through the bottom plate 19, the threaded slider 25 and the door lock device 1 in sequence until the threaded rod abuts against the positioning groove 18, the tail end of the threaded rod is hemispherical, and damage to the door lock reinforcing plate is reduced in the rotating process of the threaded rod. Three corresponding threaded sliders 25 driven by the 3 motors 15 are fixed on the bottom plate 19, and flanges 20 extend from the bottom plate 19 and the bottom plate 19 to fix the door lock device 1. The threaded slider 25 is integrally formed with the base plate 19.

The guide 14 is mounted on a robotic arm which is positioned with respect to 3 threaded rods 16 on motors 15 inserted into positioning slots 18. The rotational speed of the motor 15 is the same.

Example 2

As shown in fig. 4, the mounting portion 13 does not have the bottom plate 19, but instead, the positioning hole 17 of the door lock device 1 has a hexagonal shape. The threaded slider 25 comprises a threaded slider upper portion 21 and a threaded slider lower portion 22, the threaded slider upper portion 21 is slightly smaller in cross section than the hexagonal prism of the positioning hole 17, and the threaded slider lower portion 22 is larger in cross section than the positioning hole 17. The threaded slider upper portion 21 is inserted into the positioning hole 17 of the door lock device. The hexagonal and hexagonal prisms are only shown here, and in practice any shape can be used that allows the threaded slider 25 to be non-rotatable with the threaded rod 16.

The mechanical arm firstly strings the door lock device 1 on the threaded rods 16, then each threaded rod 16 is abutted to the positioning groove 18, after the alignment is completed, the motor 15 works, and due to the existence of a plurality of connecting points, the door lock device 1 does not rotate, but the rotation of the threaded rods 16 is converted into the back-and-forth movement of the threaded sliding blocks 25. The threaded slider 25 moves the base plate 19 to press-fit the door lock device 1 to a design position.

The door lock device 1, the door lock reinforcing plate 2 and the door inner plate 3 are connected by mounting screws 4, namely fasteners, and can not be used as countersunk screws due to the inherent thickness limitation of plates. The lower bottom surface of the spherical cap nut means that the surface thereof is convex downward like a partial spherical surface, and by this arrangement, it is possible to accommodate a large error in accuracy of the door lock reinforcement plate 2 and the door inner panel 3. The deformation of the inner vehicle door plate 3 is more continuous in the screw screwing process, the deformation degree of the inner vehicle door plate 3 is reduced, and the problem of deformation and cracking of paint on the inner vehicle door plate is reduced. Due to manufacturing variations, there may be some gaps between the door lock reinforcement plate 2 and the door inner panel 3, and when a grub screw is used, there is a problem that deformation is excessively generated to cause deformation of paint. Furthermore, by arranging the top surface of the screw parallel to the sheet, the sealing strip 5 can be passed over the screw without having to provide a distance for the sealing strip 5 and the mounting screw 4, which would otherwise be necessary, wasting the distance in the Y-direction. The door inner plate 3 is provided with a plurality of bent angles, one bent angle near the door lock is provided with a sealing strip 5, two side surfaces of the sealing strip 5 are respectively abutted between the side wall outer plate and the door inner plate 3, a gap formed between the side wall outer plate and the door inner plate 3 is separated into two spaces, the door lock is arranged in one space, and the other space is communicated with the outside. The sealing strip 5 can isolate the external dust, vibration and noise. In the semicircle cross-section of sealing strip 5, one of two boards of round one side butt, the other end is the horizontal plane, and the butt is on another board, and its both sides have the chimb respectively, and the space that chimb and horizontal plane constitute jointly is through the evacuation of extrusion mode to it is fixed. The tapered hole 9 is a concave hole having an inwardly concave spherical crown shape, and a through hole provided through the column of the mounting screw 4 is formed at the center thereof. The degree to which the tapered hole 9 is recessed inward has some interference with the door lock apparatus 1, and the interference is preset to eliminate an accuracy error due to a manufacturing deviation. The so-called extending lip 10 improves the sealing properties and reduces the likelihood of the sealing strip 5 becoming loose. The gasket 11 prevents the mounting screw 4 from crushing the mounting seat 26, so that paint on the door inner panel 3 falls off. The taper hole 9 is used for setting up the filling block 12 on the periphery through the through-hole of mounting screw 4, and when mounting screw 4 was installed, can form the cavity at the installation face of screw, door inner panel 3 and lock, and this cavity can be filled at the in-process that is extrudeed deformation to filling block 12, supplementary biography power avoids the local pressure of mounted position too big, the phenomenon of conquassation appears.
