[0010] Figure 2 It is a three-dimensional schematic diagram of the workpiece clamp. DETAILED DESCRIPTION

[0011] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0012] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0014] like Figures 1-2As shown, a car interior handle spray painting device includes a frame 1, a plurality of spray heads 2, a rotating seat 3, a workpiece clamp 4 and a motor 5. The plurality of rotating seats 3 and the spray heads 2 are linearly installed side by side on the frame 1, and the motor 5 drives the rotating seat 3 to rotate through a belt. The plurality of spray heads 2 and the rotating seat 3 are arranged one by one. The workpiece clamp 4 is detachably installed on the rotating seat 3. The workpiece clamp 4 includes a cylinder 41, a fixed plate 42, a plurality of guide columns 43, a top plate 44, a connecting rod 45, and a movable plate. 46 and a plurality of hanging clips 47, the cylinder 41 is vertically mounted on the rotating seat 3, and the output end is set upward and penetrates the fixed plate 42, a plurality of guide columns 43 are installed between the top plate 44 and the fixed plate 42, and penetrate the movable plate 46, the output end of the cylinder 41 is connected to the movable plate 46, driving the movable plate 46 to move up and down, a plurality of the hanging clips 47 are movably connected to the edge of the movable plate 46 through the pin shaft, the upper end of the connecting rod 45 is movably connected to the hanging clip 47, and the lower end of the connecting rod 45 is movably connected to the edge of the fixed plate 42. Specifically, in this embodiment, the frame 1 is used as a mounting frame, and cooperates with a transparent machine cover (not shown in the figure) to seal the spray painting environment to prevent pollution of the air in the workshop. The nozzles 2 are arranged one by one corresponding to the rotating seat 3. We adopt the method of rotating the workpiece and fixing the nozzle 2 for spraying. In order to realize multi-station synchronous spraying, we install several workpiece clamps 4 one by one on the rotating seat 3. The output end of the motor 5 drives the rotating seat 3 to rotate through the belt, and then drives the workpiece clamps 4 holding the workpiece to rotate synchronously, so as to realize multi-station spraying operation. At the same time, it can be understood that the nozzles 2 of each station can be opened and closed separately, and each workpiece clamp 4 can be used to clamp workpieces of different models and sizes, and adjust the spraying angle of the nozzle 2 to match them. Compared with the previous large-scale operation of the same model, this device can realize small-batch spraying operations of multiple models, more accurately control the spraying cost of the nozzle 2, reduce material costs, and has high efficiency and is extremely convenient and quick to adjust. Furthermore, in order to mount multiple workpieces on the workpiece gripper 4 and facilitate the loading and unloading of workpieces, the workpiece gripper 4 designed by us includes a cylinder 41, a fixed plate 42, a plurality of guide columns 43, a top plate 44, a connecting rod 45, a movable plate 46 and a plurality of hanging clips 47. First, when mounting or removing a workpiece, the output end of the cylinder 41 drives the movable plate to rise, and under the action of the connecting rod 45, a plurality of hanging clips 47 are opened, and the distance between two adjacent hanging clips 47 is increased, which is convenient for operators to mount or remove workpieces; when the mounting is completed, the output end of the cylinder 41 drives the movable plate 46 to descend, and a plurality of hanging clips 47 are gradually closed, so that when the spray head 2 is spraying, the paint is sprayed on the surface of the workpiece to avoid splashing on the top plate 44. The function of the guide column 43 is to make the movable plate 46 only move up and down to prevent deviation, and the top plate 44 can play a limiting role. The fixing plate 42 can serve as a movable connection portion at the lower end of the connecting rod 45 and cover the cylinder 41 at the same time to prevent the paint from splashing on the surface of the cylinder 41 during spraying, which is difficult to clean.

[0015] Specifically, in this embodiment, the number of the hanging clips 47 is six, which are evenly arranged around the central axis of the movable plate 46 to ensure uniform paint spraying. In other embodiments, other numbers of hanging clips 47 can be designed according to the surface area of ​​the movable plate and actual spraying needs, which is not specifically limited here.

[0016] like Figure 2 As shown, the edges of the fixed plate 42 and the top plate 44 are also provided with limit sensors 421 to prevent the movable plate 46 from colliding with the fixed plate 42 and the top plate 44 during the lifting process.

[0017] like Figure 2 As shown, the edge of the top plate 44 is provided with an avoidance groove 441 corresponding to the hanging clip 47, so that when a plurality of hanging clips 47 are folded together, collision between the hanging clips 47 and the edge of the top plate 44 is avoided.

[0018] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
