Description

Technical Field

[0001] This utility model relates to the field of vehicle frame painting technology, specifically a clamping device for vehicle frame painting. Background Technology

[0002] In the field of modern vehicle manufacturing, the chassis, as the core load-bearing component of a vehicle, directly affects the vehicle's corrosion resistance, aesthetics, and service life through its surface coating quality. Efficient and precise chassis coating processes are a key factor in ensuring vehicle quality, while the performance of the clamping device, as the basic equipment for coating operations, plays a decisive role in the coating effect.

[0003] Most existing chassis painting clamping devices adopt a fixed structure design, which makes it inconvenient to flexibly adjust the tilt angle of the chassis during actual use. This means that before painting the lower end of the chassis, it is necessary to either flip it over or suspend and clamp the chassis in the air. Flipping and suspending large chassis are cumbersome and difficult to operate. In addition, the width of automobile chassis is generally large, so when the painting robot arm is painting the side of the chassis that is far away, it needs to frequently adjust its running trajectory and distance, which increases the operating burden of the equipment, reduces the painting efficiency, and is prone to a decrease in painting accuracy due to excessive movement of the robotic arm. These problems seriously restrict the quality and efficiency of chassis painting operations. Therefore, there is an urgent need for a new type of clamping device to solve the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a clamping device for vehicle frame painting to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for vehicle frame painting, comprising a clamping worktable, a vehicle frame body disposed above the clamping worktable, a second clamp and a first clamp disposed above the clamping worktable, the first clamp and the second clamp being symmetrically arranged, a driven gear being fixed in the middle of one side surface of the first clamp, a support platform being slidably connected to the inner bottom wall of the clamping worktable, a translation slide being slidably connected below the driven gear, and a drive tooth being fixed to the upper end surface of the translation slide.

[0006] Preferably, the driving gear meshes with the driven gear, the inside of the clamping worktable has a tilting clearance space, and a gap is provided between the support platform and the inner side wall of the clamping worktable.

[0007] Preferably, a lead screw adjusting slide extends from one side of the clamping worktable, and an adjusting slide is slidably connected inside the lead screw adjusting slide.

[0008] Preferably, a clamping cylinder is fixed to one side surface of the first clamp, and the output end of the clamping cylinder is fixed to one end of the second clamp.

[0009] Preferably, the side walls of the first clamp and the second clamp are fixed with positioning posts, and the side surface of the frame body is pre-set with positioning grooves.

[0010] Preferably, the adjusting slide is connected to the lead screw thread inside the lead screw adjusting slide.

[0011] This utility model provides a clamping device for vehicle frame painting, which has the following advantages compared with the prior art:

[0012] The meshing design of the drive gear and driven gear on the translation carriage allows the first clamp to rotate, enabling adjustments to the tilt angle of the chassis body. This function not only provides convenient operating space for painting the lower end face of the chassis but also allows for changes in chassis width, facilitating the robotic arm of the painting robot to penetrate deep into the chassis for painting. This effectively reduces the robot's travel distance, improves painting efficiency, and adapts to the painting needs of chassis with different widths.

[0013] The support platform initially supports the frame, then slides outward during frame tilting and adjustment to provide space for tilting. During the painting stage, it moves out of the clamping workbench area, exposing the lower surface of the frame. This, combined with frame tilting, perfectly adapts to application scenarios requiring double-sided frame painting, ensuring uniform painting of the frame from all directions.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a clamping device for vehicle frame painting, including a clamping workbench 1, a vehicle frame body 2 is arranged above the clamping workbench 1, a second clamp 4 and a first clamp 3 are arranged above the clamping workbench 1, the first clamp 3 and the second clamp 4 are arranged symmetrically, a driven gear 7 is fixed in the middle of one side surface of the first clamp 3, a support platform 6 is slidably connected to the inner bottom wall of the clamping workbench 1, a translation slide 8 is slidably connected below the driven gear 7, and a drive tooth 11 is fixed on the upper end surface of the translation slide 8;

[0021] When the driven gear 7 drives the first clamp 3 to rotate, the frame body 2 can be flexibly controlled to maintain different tilt angles. This design not only facilitates the painting operation on the lower end surface of the frame body 2, but also reduces the width of the frame body 2 in the tilted state compared to the horizontal state, making it easier for the robotic arm of the painting robot to extend from one side to paint the deeper parts of the frame. This effectively shortens the travel distance of the painting robot in the width direction when painting the upper and lower end surfaces of the frame body 2, enabling the clamping device to assist the painting robot in adapting to painting operations on frames with different widths.

[0022] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the drive gear 11 is meshed with the driven gear 7, the inside of the clamping worktable 1 is provided with a flipping clearance space 12, and a gap is provided between the support platform 6 and the inner side wall of the clamping worktable 1.

[0023] During the tilting and adjustment of the frame body 2, the support platform 6 slides outward simultaneously, providing space for the tilting of the frame body 2 and supporting the frame body 2 in the initial stage. During painting, the clamping workbench 1 area is removed to expose the lower end of the frame body 2, meeting the requirements for double-sided painting.

[0024] Further as Figure 1 , Figure 2 and Figure 4As shown, it is worth noting that a clamping cylinder 5 is fixed to one side surface of the first clamp 3, and the output end of the clamping cylinder 5 is fixed to one end of the second clamp 4. Positioning posts are fixed to the opposite side walls of the first clamp 3 and the second clamp 4, and positioning grooves are pre-set on the side surface of the frame body 2. Before use, the clamping workbench 1 is placed in the ground groove, and the frame body 2 is positioned on the support platform 6 between the first clamp 3 and the second clamp 4. At this time, the clamping cylinder 5 is activated, driving the second clamp 4 to retract towards the first clamp 3, so that the positioning posts on the first clamp 3 and the second clamp 4 are embedded into the positioning grooves of the frame body 2, completing the clamping and positioning of the frame body 2.

[0025] Further as Figure 3 As shown, it is worth noting that a lead screw adjusting slide 9 extends from one side of the clamping worktable 1. An adjusting slide 10 is slidably connected inside the lead screw adjusting slide 9, and the adjusting slide 10 is threadedly connected to the lead screw inside the lead screw adjusting slide 9.

[0026] The device uses a motor to drive a lead screw to rotate within the adjusting slide 9. Utilizing the characteristics of the threaded joint, the rotational motion of the lead screw is converted into the linear motion of the adjusting slide 10. Because the thread pitch is fixed, for each rotation of the lead screw, the adjusting slide 10 moves one thread pitch along the lead screw axis, achieving precise displacement control. The adjusting slide 10 drives the translation slide 8 to slide along one side surface of the clamping table 1. Since the upper surface of the translation slide 8 has a partial drive tooth 11, initially, the drive tooth 11 does not contact the driven gear 7, and no transmission occurs. When the translation slide 8 moves to the point where the drive tooth 11 meshes with the driven gear 7, the driven gear 7 is driven to rotate, thereby causing the first clamp 3 to rotate on the clamping table 1.

[0027] The solution has the following working process: Before use, the clamping workbench 1 is built into the groove in the ground, and the frame body 2 is positioned on the support platform 6 between the first clamp 3 and the second clamp 4. The clamping cylinder 5 drives the second clamp 4 to retract towards the first clamp 3, so that the positioning pins on the first clamp 3 and the second clamp 4 are embedded in the positioning groove of the frame body 2. In this way, the first clamp 3 and the second clamp 4 can cooperate to clamp and position the frame body 2.

[0028] The lead screw is driven by a motor to rotate, and the rotational motion of the lead screw is converted into the linear motion of the adjusting slide 10 through the threaded joint. Since the thread pitch is fixed, the adjusting slide 10 moves a distance of one thread pitch along the axis of the lead screw for each rotation of the lead screw, achieving precise displacement control. The adjusting slide 10 drives the translation slide 8 to slide along one side surface of the clamping table 1. The upper end surface of the translation slide 8 is partially provided with drive teeth 11. In this way, the translation slide 8 will not cause transmission to the driven gear 7 in the initial stage of operation when it drives the support table 6. When the driven gear 7 contacts and meshes, it drives the first clamp 3 to rotate on the clamping worktable 1. During the tilting and adjustment of the frame body 2, the support platform 6 slides outward synchronously and provides operating space for the tilting and adjustment of the frame body 2. In the initial stage, the support platform 6 can support the frame body 2. In the painting stage, the support platform 6 moves away from the clamping worktable 1 area to expose the lower end face of the frame body 2 so that the painting work can proceed smoothly. This method of exposing the upper and lower end faces of the frame body 2 is suitable for the application scenario of double-sided painting.

[0029] When the driven gear 7 drives the first clamp 3 to rotate, it can control the frame body 2 held between the first clamp 3 and the second clamp 4 to maintain different tilt angles. On the one hand, this facilitates the painting work on the lower end surface of the frame body 2. On the other hand, the tilted frame body 2 has a width reduction effect compared to the horizontal state. This allows the robotic arm of the painting robot to extend from one side of the frame body 2 and paint the deep parts, thereby reducing the running distance of the painting robot when painting the upper and lower end surfaces of the frame body 2. This clamping device helps the painting robot adapt to the painting operation of frame bodies 2 with different widths.
