Description

Technical Field

[0001] This utility model belongs to the field of automotive sheet metal painting, and in particular relates to a positioning mechanism for automotive sheet metal painting. Background Technology

[0002] Automotive sheet metal work is a technical method of car repair. In this context, automotive sheet metal work is equivalent to automotive sheet metal repair, which refers to the repair of a car body after a collision. This includes all work except for anti-corrosion and decorative painting of the car body.

[0003] According to a published application (CN 217249882 U), an automotive sheet metal painting device includes a bracket, a moving mechanism, and a transmission mechanism. The moving mechanism includes a fixed plate, a crossbeam, and a sliding plate. The crossbeam is fixedly installed on the top of the bracket, and its surface is slidably connected to the sliding plate. The bottom of the extension plate is rotatably connected to a pulley. The transmission mechanism includes a fixed tube, a guide rod, and a piston. The fixed tube is fixedly connected to the side wall of the crossbeam, the end of the guide rod is fixedly connected to the piston, and the side end of the fixed tube is fixedly connected to a connecting tube. This application features a crossbeam that enables stable movement of the sliding plate, and the combination of pulleys and rails further improves stability during movement, which is beneficial for ensuring uniformity during automotive sheet metal painting and improving the production quality of automotive sheet metal parts. The fixed tube and guide rod enable movement of the sliding plate, and the operation of an air pump allows for back-and-forth movement of the housing, facilitating painting of larger sheet metal parts and ensuring uniform protrusion.

[0004] The aforementioned application uses a fixed plate, a crossbeam, and a sliding plate. The crossbeam is fixedly mounted on the top of the bracket, which makes it impossible to position and clamp the automotive sheet metal, resulting in displacement during painting. Therefore, we propose a positioning mechanism for painting automotive sheet metal parts that can position and clamp the automotive sheet metal during painting. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning mechanism for painting automotive sheet metal parts. Through the rotation of the motor output shaft and the interaction of components such as gears, racks, push plates, paint spray boxes, paint outlets, material conveying pipes, and paint spray blocks within the painting device, the mechanism achieves the following: when the gear rotates clockwise, it pushes the rack forward; when the rack moves forward, it drives the push plate forward; when the push plate moves forward, it pushes the push column into the paint spray box; and when the push column moves into the paint spray box, it drives the push plate into the paint spray box. This achieves the functions of moving the rack and the push plate, allowing paint to be squeezed onto the paint spray block and then sprayed onto the automotive sheet metal, thus solving existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a positioning mechanism for painting automotive sheet metal parts, including a worktable, with a support leg fixedly connected to the bottom of the worktable and a positioning device provided on the top of the worktable.

[0008] The positioning device includes a motor, the bottom of which is fixedly connected to the top of the worktable. The output shaft of the motor is fixedly connected to a bidirectional threaded rod. A threaded sleeve is threadedly connected to the circumferential surface of the bidirectional threaded rod. A clamping plate is fixedly connected to the circumferential surface of the threaded sleeve. A fixing plate is fixedly connected to the side of the clamping plate. A pressure plate is slidably connected to the side of the clamping plate.

[0009] Furthermore, a bolt is fixedly connected to the bottom of the pressure plate, the circumferential surface of the bolt penetrates the bottom of the fixed plate, the circumferential surface of the bolt is slidably connected to the inner wall of the fixed plate, and a nut is threaded onto the circumferential surface of the bolt. The function of the bolt and the nut is to hold the automotive sheet metal placed between the fixed plate and the pressure plate.

[0010] Furthermore, a limiting rod is fixedly connected to the side of the motor. The circumferential surface of the limiting rod penetrates the side of the threaded sleeve, and the circumferential surface of the limiting rod is slidably connected to the inner wall of the threaded sleeve. The function of the limiting rod is to limit the displacement of the threaded sleeve.

[0011] Furthermore, the number of threaded sleeves, clamping plates, fixing plates, pressure plates, bolts, and nuts is set to two each and is symmetrical to each other along the vertical central axis of the worktable. The purpose of setting the number of threaded sleeves, clamping plates, fixing plates, pressure plates, bolts, and nuts to two each and being symmetrical to each other along the vertical central axis of the worktable is to better clamp and position the automotive sheet metal.

[0012] Furthermore, a painting device is provided on the top of the workbench. The painting device includes a gear, the side of which is fixedly inserted through the circumference of a bidirectional threaded rod. A rack is slidably connected to the top of the workbench, and a push plate is fixedly connected to the front side of the rack. A paint spray box is fixedly connected to the top of the workbench. A paint outlet is opened on the side of the paint spray box, and a material conveying pipe is fixedly connected to the inner wall of the paint outlet. A paint spraying block is fixedly connected to one end of the material conveying pipe. The push plate is used to push the push column to move the push plate into the paint spray box.

[0013] Furthermore, a push post extends through the back side of the paint spray box, and the circumferential surface of the push post is slidably connected to the inner wall of the paint spray box. A push plate is fixedly connected to the front side of the push post, and a spring is fixedly connected to the circumferential surface of the push post. The end of the spring away from the push post is fixedly connected to the back side of the paint spray box. The function of the spring is to allow the push post to reset using the elastic force of the spring when the push plate stops pushing the push post.

[0014] Furthermore, the circumferential surface of the gear meshes with the top of the rack, and the back side of the push column is located on the displacement trajectory of the push plate. The purpose of meshing the circumferential surface of the gear with the top of the rack is to drive the rack to move when the gear rotates.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model achieves the positioning of automotive sheet metal by cooperating with the rotation of the motor output shaft and the components such as the bidirectional threaded rod, threaded sleeve, clamping plate, fixing plate, and pressure plate inside the positioning device. When the bidirectional threaded rod rotates, it can drive the two threaded sleeves to move towards the middle. When the two threaded sleeves move towards the middle, they can drive the clamping plate to move towards the middle, thus achieving the movement of the threaded sleeves and the clamping plate, which enables the positioning of automotive sheet metal.

[0017] 2. This utility model achieves the effect of the rotation of the motor output shaft in conjunction with the gears, racks, push plates, paint spraying box, paint outlet, material conveying pipe, paint spraying block and other components inside the painting device. When the gear rotates clockwise, it can push the rack forward. When the rack moves forward, it can drive the push plate forward. When the push plate moves forward, it can push the push column into the paint spraying box. When the push column moves into the paint spraying box, it can drive the push plate into the paint spraying box. This achieves the function of moving the rack and the push plate, so that the paint can be squeezed into the paint spraying block and then sprayed onto the automotive sheet metal.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
