Description
Technical Field
[0001] This utility model relates to a manually rotatable paint spraying fixture, belonging to the technical field of automotive paint spraying and turning equipment. Background Technology
[0002] With the rapid development of automotive technology, paint is now a common surface treatment process for automotive interior and exterior parts, resulting in aesthetically pleasing and corrosion-resistant components. The painting process for automotive parts requires high-volume, repetitive, and efficient production; therefore, a well-designed and easily accessible painting fixture is essential. Current painting processes require placing the product, back side up, onto a first fixture and painting the back. After the paint dries, the product is removed from the first fixture, placed front side up onto a second fixture, and then painted. This process involves two parts handling steps and switching between two fixtures, resulting in numerous steps, low efficiency, and increased costs due to the need for two sets of fixtures. Utility Model Content
[0003] To address the problems existing in the prior art, this utility model proposes a manually rotatable spray painting fixture, which aims to spray multiple parts at once and complete the spraying of both the front and back sides of the parts in one go, thereby improving spraying efficiency and yield.
[0004] The technical solution adopted by this utility model is a manually rotatable spray painting fixture, including a base, a rocker arm, a rotating shaft, a chuck, and a mounting frame. The rotating shaft passes through the mounting frame and is rigidly connected. Both ends of the rotating shaft are connected to the base through bearings. The rocker arm is installed at one end of the rotating shaft. The chuck is set on the mounting frame and is used to fix the parts to be sprayed. The mounting frame is rotated by manually rotating the rocker arm.
[0005] Furthermore, the plurality of claws are spaced apart on the mounting frame.
[0006] Furthermore, a counterweight is installed on one side of the mounting frame, and when the mounting frame is parallel to the bottom surface of the base, the counterweight overlaps the base.
[0007] Furthermore, the rigid connection is a key connection or a pin connection.
[0008] Furthermore, one end of the claw is fixed to the mounting bracket, and the other end of the claw has a beveled angle for engaging with the part.
[0009] This utility model discloses a manually rotatable spray painting fixture. Its advantages are that, compared with the prior art, this utility model uses a rotating rocker arm to drive the mounting frame to rotate and utilizes the stable support force provided by the counterweight to complete the painting of both sides in one go, reducing the worker's turning actions; only one set of fixtures is required, reducing equipment investment and maintenance costs; the design of the chuck and the slot of the part to cooperate avoids the positioning deviation caused by multiple pick-and-place operations, and improves the consistency of painting and the yield rate.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this utility model or its application or use. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] To further understand the content of this utility model, the technical solution will be further described below in conjunction with specific embodiments.
[0019] Example 1: As Figures 1-5 As shown, this embodiment provides a manually rotatable spray painting fixture, including a base 6, a rocker arm 2, a rotating shaft 5, claws 4, and a mounting frame 7. The base 6 is used to fix the entire fixture; the rocker arm 2 serves as the rotational power, driving the mounting frame 7 to rotate; the rotating shaft 5 provides rotational freedom; the mounting frame 7 is used to mount the claws 4 and transmit rotational power; the claws 4 are used to fix the part 1 to be painted. The rotating shaft 5 passes through the mounting frame 7 and is rigidly connected. Both ends of the rotating shaft 5 are connected to the base 6 via bearings 8. The rocker arm 2 is mounted on one end of the rotating shaft 5. The claws 4 are mounted on the mounting frame 7 and are used to fix the part 1 to be painted. The twelve claws 4 are spaced apart on the mounting frame 7. A counterweight 3 is mounted on one side of the mounting frame 7. When the mounting frame 7 is parallel to the bottom surface of the base 6, the counterweight 3 overlaps the base 6, providing stable support. The rigid connection adopts a keyed connection. Specifically, a keyway is machined in the center hole of the mounting bracket 7. The circumferential fixation of the rotating shaft 5 and the mounting bracket 7 is achieved by the cooperation of the flat key and the keyway. The mounting bracket 7 can rotate on the base 6 around the rotating shaft 5 as the rocker arm 2 rotates. The mounting bracket 7 is fixed on the base 6 by the rotating shaft 5. The rotation of the rocker arm 2 drives the part 1 mounted on the mounting bracket 7 to rotate, so that the front and back of the part 1 can be aligned with the spray gun for painting in sequence.
[0020] Example 2: As Figures 1-5 As shown, this embodiment differs from Embodiment 1 in that the rigid connection is a pin connection. Specifically, the rotating shaft 5 is machined with positioning pin holes, and the mounting bracket 7 has corresponding pin holes of the same diameter. The rotating shaft 5 and the mounting bracket 7 are circumferentially fixed by inserting cylindrical pins into the pin holes. In a specific implementation of this embodiment, one end of the claw 4 is fixed to the mounting bracket 7, and the other end of the claw 4 has a bend 9, which is used to engage with the part 1. In this embodiment, the part 1 to be painted is a car horn grille. The horn grille has four slots 10 on its inner side, and the bend 9 engages with the slots 10. Specifically, the bend 9 of the claw 4 can be embedded in the slots 10, achieving rapid positioning and fixation of the part 1.
[0021] Taking Example 2 as an example, such as Figures 1-5As shown, the working process of this utility model is specifically described. When using it, the speaker covers are first installed one by one onto the corresponding claws 4. Specifically, the angle of the folding angle 9 matches the slot 10. Press down forcefully to make the folding angle 9 embed into the slot 10, thus completing the fixation of a single speaker cover. After all the speaker grilles are installed, manually rotate rocker arm 2 so that the front of the speaker grille is horizontally facing upwards. At this time, the mounting bracket 7 is parallel to the bottom surface of the base 6, and the two counterweights 3 are attached to the base 6. Under the action of the counterweights 3, the counterweights 3 are subjected to both gravity and the supporting force of the base 6 in the vertical direction, so that the entire fixture is in a stable state. At this time, the spray gun sprays from top to bottom to complete the front spraying of the product, ensuring uniform paint film coverage. Subsequently, manually rotate rocker arm 2 so that the speaker grille and the claw 4 rotate 180° clockwise. At this time, the mounting bracket 7 is still parallel to the bottom surface of the base 6, and the two counterweights 3 are attached to the base 6. Under the action of the counterweights 3, the entire fixture is in a stable state, and the back of the speaker grille, that is, the inner side, is horizontally facing upwards. At this time, the spray gun sprays from top to bottom to complete the back spraying of the speaker grille. This utility model realizes continuous spraying of both sides of part 1 through a single set of fixtures, reducing the number of fixtures and process steps, improving production efficiency, and reducing production costs. This invention solves the problems of traditional spray painting processes, which require two sets of fixtures, involve complicated procedures, and are inefficient.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
