Description

Technical Field

[0001] The utility model relates to the technical field of coating, in particular to a limiting device for a powder coating production line of small sheet metal parts. Background Art

[0002] Powder coating is the process of spraying powder coating onto the surface of a workpiece using powder spraying equipment (electrostatic spraying machine). Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating; the powdery coating is then baked and leveled and solidified at high temperature to become a final coating with different effects (different types of powder coating effects).

[0003] In the prior art, for example, the utility model patent with application number CN202323429978.3 discloses a limited-position spraying device, comprising: a clamping assembly, which is installed inside a mounting plate and a processing table. The clamping assembly comprises a dual-axis motor, a rotating rod, a movable frame and a splint; the dual-axis motor is installed inside the processing table; the rotating rod is rotatably connected to the inside of the processing table and fixedly connected to the output shafts on both sides of the dual-axis motor; the movable frame is movably connected to the inside of the mounting plate and is threadedly connected to the rotating rod; the splint is fixedly connected to the movable frame and is located above the conveyor belt. This device limits the metal product to be sprayed by setting a clamping assembly, so that the metal product can be aligned with the nozzle so that the metal product can be sprayed evenly. In actual use, due to the irregular shape of the sheet metal, when an integral splint is used, it contacts the local protruding position, the clamping stability is insufficient, and the limiting effect is not ideal.

[0004] Therefore, it is necessary to propose a limiting device for a small sheet metal part powder coating production line to at least partially solve the problems existing in the prior art. Utility Model Content

[0031] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0032] Example

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] like Figure 1 、 2As shown, the limiting device for a small sheet metal powder coating production line provided in this embodiment includes:

[0035] Electric push rod 1, which is connected to both sides of the machine platform 2. A conveyor belt 4 for transporting small sheet metal parts 3 is provided above the machine platform 2. The electric push rod 1 feeds in the horizontal direction;

[0036] The limiting frame 5 is connected to the output end of the electric push rod 1, and two first limiting plates 6 are symmetrically connected to the upper and lower parts of the limiting frame 5.

[0037] Two support platforms 7 are symmetrically connected to both sides of the machine platform 2 , and the electric push rod 1 is horizontally arranged on the support platforms 7 .

[0038] The working principle and beneficial effects of the utility model are as follows:

[0039] The limiting device for the powder coating production line of small sheet metal parts provided in this embodiment is arranged at the coating station of the coating production line and is located below the coating spray gun; after the conveyor belt 4 transports the small sheet metal part 3 to the coating station, the small sheet metal part 3 is located between the two first limiting plates 6, and the electric push rod 1 is started to drive the limiting frame 5 to move toward the center of the conveyor belt 4, and the first limiting plate 6 moves to contact the small sheet metal part 3 and clamps it; the first limiting plate 6 is set to two upper and lower parts, so that it can clamp the upper and lower parts of the small sheet metal part 3 respectively.

[0040] Through the above structural design, two first limiting plates 6 arranged upper and lower are used to clamp the upper and lower parts of the small sheet metal part 3 at the same time, thereby improving the stability of the limiting clamping and solving the problem that the irregular local shape of the small sheet metal part 3 affects the limiting effect.

[0041] like Figure 2 、 3 As shown, in one embodiment, the limiting frame 5 is configured as a C-shaped frame, the upper and lower ends of the limiting frame 5 are respectively connected to the two first limiting plates 6 , and the middle portion of the limiting frame 5 is connected to the electric push rod 1 .

[0042] There are two limit frames 5 , and the two limit frames 5 are symmetrically arranged along the length direction of the first limit plate 6 . The output end of the electric push rod 1 is connected to the fixed plate 8 , and the middle parts of the two limit frames 5 are connected to the fixed plate 8 .

[0043] A second limiting plate 11 is provided on one side of the first limiting plate 6 close to the center of the machine 2 . A plurality of buffer components are evenly connected between the first limiting plate 6 and the second limiting plate 11 . The second limiting plate 11 is arranged parallel to the first limiting plate 6 .

[0044] The working principle and beneficial effects of the above technical solution are:

[0045] The limiting frame 5 is configured to be C-shaped, and the middle parts of the two limiting frames 5 are simultaneously connected to the fixed plate 8 to keep the two limiting frames 5 stably installed. The two limiting frames 5 jointly support the two first limiting plates 6; a second limiting plate 11 is movably provided on the first limiting plate 6, and the second limiting plate 11 always has a tendency to move away from the first limiting plate 6. When the small sheet metal part 3 is clamped, the second limiting plate 11 first contacts the small sheet metal part 3. As the clamping force increases, the second limiting plate 11 is pressed and moves toward the first limiting plate 6 until the clamping force reaches a preset value. The clamping force can be detected by a pressure sensor. The upper and lower second limiting plates 11 will move different distances according to the shape of the small sheet metal part 3 to maintain a close fit with the upper and lower parts of the small sheet metal part 3, thereby improving the limiting effect on the small sheet metal part 3.

[0046] like Figure 2 As shown, in one embodiment, both ends of the first limiting plate 6 and the second limiting plate 11 are bent toward a side away from the center of the machine platform 2 .

[0047] The working principle and beneficial effects of the above technical solution are:

[0048] Both ends of the first limiting plate 6 and the second limiting plate 11 are set to be bent, which effectively prevents the limiting plate from entering the recessed position of the small sheet metal part 3 and getting stuck during the limiting clamping process, thereby facilitating the separation of the limiting plate from the small sheet metal part 3.

[0049] like Figure 2 、 3 As shown, in one embodiment, the buffer assembly includes: two sets of sliding assemblies respectively arranged on the opposite sides of the first limiting plate 6 and the second limiting plate 11, and the sliding assemblies include:

[0050] Mounting blocks 12, two mounting blocks 12 are connected to the side surfaces of the limiting plate;

[0051] A slide bar 13 connected between the two mounting blocks 12;

[0052] The two sliding members 14 are slidably connected to the sliding rod 13 , and a spring 19 is connected between the sliding member 14 and the mounting block 12 , and the spring 19 is sleeved on the sliding rod 13 .

[0053] The buffer assembly further includes a connecting rod 15 . The two connecting rods 15 are cross-arranged and hinged at the intersection. Both ends of the connecting rod 15 are respectively hinged to the sliding members 14 of the two sets of sliding assemblies.

[0054] The working principle and beneficial effects of the above technical solution are:

[0055] When the buffer assembly is in use, as the second limit plate 11 moves toward the first limit plate 6, the two groups of sliding assemblies are driven to move closer to each other, so that the two connecting rods 15 are located at one end of the same slide bar 13 and move away from each other, that is, the two sliding parts 14 on the same slide bar 13 move away from each other. When the sliding part 14 moves, pressure is applied to the spring 19 and energy is stored. The second limit plate 11 fits tightly with the small sheet metal part 3 with the help of the elastic force of the spring 19; at the same time, when in contact with the small sheet metal part 3, the spring 19 can reduce the impact on the small sheet metal part 3 and reduce damage and deformation of the workpiece.

[0056] like Figure 4 、 5 As shown, in one embodiment, a plurality of conformal blocks 16 are evenly connected to one side of the second limiting plate 11 close to the center of the machine platform 2 .

[0057] A plurality of circular holes 17 are evenly arranged on one side of the second limiting plate 11 close to the center of the machine 2 . The follower block 16 is slidably connected in the circular hole 17 , and a return spring 18 is connected between the end of the follower block 16 and the bottom of the circular hole 17 .

[0058] The working principle and beneficial effects of the above technical solution are:

[0059] A follower block 16 is provided on the second limiting plate 11, and the follower block 16 is elastically provided in the circular hole 17. When the second limiting plate 11 contacts the small sheet metal part 3, the follower block 16 at each position is subjected to pressure from the surface of the small sheet metal part 3, and can protrude different lengths from the second limiting plate 11, so that the follower block 16 at each position can fit the surface of the small sheet metal part 3, reducing the clamping gap between the second limiting plate 11 and the small sheet metal part 3, being applicable to small sheet metal parts 3 of different shapes, and improving the limiting stability and adaptability.
