[0002] In the process of automobile production, due to the metal characteristics of the body parts themselves, automobile parts often need to be painted. The traditional painting method is manual painting, which has high labor intensity and low efficiency and cannot meet the requirements of industrialized production.

[0003] After searching, the Chinese patent announcement number CN216396779U discloses "a paint spraying device for vehicle parts production, including a box body, a cross slot, a screw, a cross moving block, a paint spraying tray, a rear side closing plate, a front side closing plate, a blower, a blower output end, left and right side openings, a plug, a feed rack, a cleaning feeding device, a base, a heating box, a paint box, a U-shaped drying and heating tube, a bottom recovery structure, a discharge plate, a flip structure and a mobile suction structure. A cross slot is arranged on the top of the box body and a screw driven by a motor is installed therein. The screw is used to cooperate with the cross moving block to move along the cross slot, and at the same time, the paint spraying tray installed below it by an electric push rod is driven to move and spray paint. The electric push rod can adjust the height of the jet disc from the material plate to achieve the painting effect of the material number. The front and rear sides of the box body are respectively closed front and rear closing plates, which close the box body, and the blower is evenly distributed on the outside of the front side plate."

[0004] The above patent realizes mobile painting of the workpiece by rotating the lead screw to make the cross moving block drive the jet disk to move horizontally.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1~Figure 5As shown, this embodiment proposes a painting equipment for vehicle parts production, including a box body 1, a placement seat 2 for placing a workpiece is fixedly connected to the top wall inside the box body 1, and positioning mechanisms 3 for clamping and fixing the workpiece are arranged at both ends of the placement seat 2. A painting mechanism 4 is arranged above the placement seat 2, and the painting mechanism 4 includes a guide rail 41, which is fixedly connected to the outside of the box body 1, and a movable seat 42 is slidably connected to the guide rail 41. A motor 43 is fixedly installed on one side of the movable seat 42, and the output shaft of the motor 43 is fixedly connected to a rotating shaft 44, and the rotating shaft 44 passes through the side wall of the box body 1. , and extends to the inner side of the box body 1, the rotating shaft 44 is slidably connected with the side wall of the box body 1, and a slide groove 40 matching the rotating shaft 44 is opened on the outer wall of the box body 1, the rotating shaft 44 is slidably connected with the inner wall of the slide groove 40, one end of the rotating shaft 44 is fixedly connected with a reciprocating screw 45, and a mounting seat 46 is threadedly connected on the reciprocating screw 45, the top end of the mounting seat 46 is slidably connected with the top wall of the box body 1, and the bottom end of the mounting seat 46 is fixedly connected with a paint spray head 47, and one end of the reciprocating screw 45 is provided with a transmission member 49 which drives the reciprocating screw 45 to intermittently translate laterally by cooperating with the rotation of the reciprocating screw 45.

[0024] The motor 43 drives the rotating shaft 44 to rotate, which makes the reciprocating screw 45 rotate on its own, and the mounting seat 46 reciprocates along the axial direction of the reciprocating screw 45, so that the paint head 47 follows the reciprocating screw 45 to perform longitudinal reciprocating translation. When the reciprocating screw 45 rotates, the transmission member 49 drives the reciprocating screw 45 to translate laterally, which makes the paint head 47 follow the reciprocating screw 45 to translate laterally, so that the paint spraying range of the paint spray head 47 can completely cover the workpiece and spray the paint evenly on the workpiece, effectively avoiding the problem of uneven local paint spraying of the workpiece.

[0025] Further, guide members 48 are provided at both ends of the inner side of the box body 1, and the guide members 48 include guide plates 481, which are fixedly connected to the inner wall of the box body 1, and guide grooves 482 matching the reciprocating screw rod 45 are provided on the guide plates 481, and the two ends of the reciprocating screw rod 45 are respectively slidably connected to the inner walls of the two guide grooves 482, and the guide plates 481 are L-shaped structures, and the part of the guide plates 481 perpendicular to the reciprocating screw rod 45 is slidably connected to the reciprocating screw rod 45. The guide plates 481 can support and guide the reciprocating screw rod 45, thereby ensuring that the reciprocating screw rod 45 can be stably translated.

[0026] Furthermore, the transmission member 49 includes a mounting plate 491, one side of which is slidingly connected to the corresponding guide plate 481, the top of the mounting plate 491 is rotatably connected to one end of the reciprocating screw rod 45, the end of the reciprocating screw rod 45 is fixedly connected to a gear 1 492, the bottom end of the mounting plate 491 is rotatably connected to a gear 2 493 meshing with the gear 1 492, one side of the gear 2 493 is coaxially fixedly connected to an incomplete gear 494, the inner wall of the box body 1 is fixedly connected to a toothed plate 495, the incomplete gear 494 is intermittently meshed with the toothed plate 495, the number of teeth of the gear 1 492 is less than the number of teeth of the gear 2 493, and the number of teeth of the incomplete gear 494 is less than the number of teeth of the gear 2 493. When the reciprocating screw 45 rotates, it will drive gear 1 492 to rotate, so that gear 2 493 drives the incomplete gear 494 to rotate synchronously. Since the number of teeth of gear 2 493 is greater than that of gear 1 492, the rotation speed of gear 2 493 is less than that of gear 1 492. When the reciprocating screw 45 rotates a certain angle so that the mounting seat 46 moves from one end of the reciprocating screw 45 to the other end, the incomplete gear 494 is meshed with the tooth plate 495, which makes the mounting plate 491 drive the reciprocating screw 45 to move horizontally as a whole, so that the paint head 47 follows the reciprocating screw 45 to move horizontally.

[0027] Furthermore, the positioning mechanism 3 includes a slide bar 31, which penetrates the side wall of the box body 1 and is slidably connected to the side wall of the box body 1, one end of the slide bar 31 is fixedly connected to a clamping plate 32, the other end of the slide bar 31 is fixedly connected to a stopper 33, and a spring 34 is sleeved on the slide bar 31, one end of the spring 34 abuts against the clamping plate 32, and the other end of the spring 34 abuts against the inner wall of the box body 1. The workpiece is clamped and fixed by the clamping plate 32, and the spring 34 can apply pressure to the clamping plate 32, which enables the clamping plate 32 to continuously clamp the workpiece.

[0028] Working principle: The motor 43 drives the rotating shaft 44 to rotate, which makes the reciprocating screw 45 rotate on itself, and makes the mounting seat 46 reciprocate and translate along the axial direction of the reciprocating screw 45, so that the paint spray head 47 follows the reciprocating screw 45 to perform longitudinal reciprocating translation. When the reciprocating screw 45 rotates, it will drive gear 1 492 to rotate, so that gear 2 493 drives the incomplete gear 494 to rotate synchronously. Since the number of teeth of gear 2 493 is greater than that of gear 1 492, the rotation speed of gear 2 493 is less than that of gear 1 492. When the reciprocating screw 45 rotates a certain angle to make the mounting seat 46 move from one end of the reciprocating screw 45 to the other end, the incomplete gear 494 is meshed with the tooth plate 495, which makes the mounting plate 491 drive the reciprocating screw 45 to translate horizontally as a whole, so that the paint spray head 47 follows the reciprocating screw 45 to translate horizontally, so that the paint spraying range of the paint spray head 47 can completely cover the workpiece and spray the paint evenly on the workpiece.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
