Description

Technical Field

[0001] The invention relates to the technical field of automobile shell inner wall processing equipment, in particular to an automobile shell inner wall processing device. Background Art

[0002] Automated spray painting equipment for automotive interior cavities is a specialized device used for coating the interior surfaces of vehicle bodies. Its operating principle is that after the body shell is secured by a clamping mechanism, a multi-axis motion system drives an atomizing spray gun to move in a three-dimensional trajectory, achieving paint coverage of the interior surface. A typical current spray painting system primarily consists of a clamping mechanism, a translational slide, an elevating slide, and an atomizing spray gun. A servo drive controls the spray gun's combined horizontal and vertical motion in the XY plane, while a paint delivery system is connected to the spray gun to perform the spraying operation.

[0003] While this infrastructure is capable of completing routine spraying tasks, it suffers from significant technical drawbacks in practical applications: the interiors of modern automobiles often exhibit complex three-dimensional curved surfaces, including irregular, uneven structures, due to design and functional requirements. Existing equipment employs a fixed spraying elevation angle, which causes the distance between the atomizing spray gun and the surface to fluctuate significantly with changes in the surface curvature. Specifically, in raised areas, the spray gun's working distance is shortened, increasing the amount of paint deposited; in recessed areas, the increased spray gun spacing reduces the amount of paint coverage per unit area. This dynamically changing spray distance directly leads to uneven paint film thickness distribution, resulting in light and dark color differences after curing, seriously affecting the coating's appearance quality and anti-corrosion performance. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for processing the inner wall of an automobile shell, which can spray the inner wall of the shell.

[0017] Beneficial effects of the present invention: The present invention realizes lateral and longitudinal displacement by a moving rod arranged on the base, and utilizes the moving rod to link the lifting rod to drive the rotating ball for position adjustment.

[0028] like Figures 1 to 5 , Example 1:

[0029] A device for processing the inner wall of an automobile shell comprises: a base 1, a clamping member 2 disposed on the base 1, and a spray head 3. The clamping member 2 is used to clamp the shell and is mainly composed of a clamping plate and a cylinder 1 connected together.

When the moving rod 4 moves, the rotating ball 7 contacts the concave and convex surface of the shell. When the rotating ball 7 contacts the concave and convex surface of the shell, the rotating ball 7 will push the lifting rod 5 to move up and down. Once the lifting rod 5 is lifted or lowered, the lifting rod 5 will contact the detection part. Once the detection part contacts the lifting rod 5, the detection part detects the height of the lifting rod 5 and controls the mobile lifting part 8 set on the base 1 to start, so that the mobile lifting part 8 drives the nozzle 3 set on the mobile lifting part 8 to move up and down, thereby achieving the spraying of the shell by the nozzle 3.

The screw 18 is mainly driven by the motor five, which is fixedly connected to the bracket 17, and the output shaft is fixedly connected to the screw 18, so that the rotation of the screw 18 can be realized. Once the screw 18 rotates, the screw 18 will drive the bracket 17 to move, so that the bracket 17 pushes the connecting seat 16 to move, and then the connecting seat 16 drives the nozzle 3 fixedly connected to the bottom of the connecting seat 16 to move, thereby realizing the adjustment of the position of the nozzle 3 and the transmission of the nozzle 3.

[0034] The detection component of the present invention includes: a push rod 9, a push seat 10, a sensing block 11, a distance sensor 12 and a control component 13. The push rod 9 is fixedly connected to the top of the lifting rod 5, the push seat 10 is elastically slidably connected to the mobile rod 4, the push seat 10 and the lifting rod 5 are arranged opposite to each other, the sensing block 11 is fixedly connected to the push seat 10, the distance sensor 12 is fixedly connected to the mobile rod 4 and is arranged opposite to the sensing block 11, and the control component 13 is arranged on the base 1. The control component 13 can control the horizontal, longitudinal and vertical movement of the mobile lifting component 8 nozzle 3. The control component 13 is electrically connected to the distance sensor 12. The control component 13 is a control panel. When the rotating ball 7 is in the outer shell When the inner wall moves, the lifting rod 5 moves up and down.

Once the sensing block 11 rises and falls, the distance sensor 12 senses the rise and fall of the sensing block 11. The distance sensor 12 senses the rise and fall of the sensing block 11 and transmits a signal to the control panel electrically connected to it, so that the control panel detects the up and down fluctuation of the distance sensor 12 and transmits a signal to the motor three, motor four and motor five electrically connected to it. The motor three, motor four and motor five control the distance between the nozzle 3 and the shell to always maintain it in a specific range, thereby achieving uniformity of spraying inside the shell.

[0035] Specifically, since the lifting seat 15 is fixedly connected to the support platform 24, the bracket 17 is slidably connected to the support platform 24, the bracket 17 is fixedly connected to the support rod 25, one end of the support rod 25 is fixedly connected to the pushing seat 10, the side wall of the support rod 25 is slidably connected to the lifting seat 15, and the sliding seat 14 is fixedly connected to the limit rod 26, which can be attached to the top surface of the lifting seat 15.
