Description

Technical Field

[0001] This utility model belongs to the field of mechanical parts processing technology, and specifically relates to a painting device for mechanical parts processing. Background Technology

[0002] In the field of mechanical parts processing, flange units are common connecting components, and their surface painting treatment is a key process to ensure corrosion resistance and aesthetics.

[0003] Although existing painting equipment has basic painting functions, it still relies on complex mechanical structures for flange fixing. Most equipment uses external clamping or bolt fixing methods, which requires multiple adjustments with tools, which is time-consuming and labor-intensive, and does not achieve rapid loading and unloading, thus affecting painting efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a painting device for machining mechanical parts, which can easily complete the installation or disassembly of the flange unit in the flange unit painting process, thus facilitating the painting treatment of the flange unit.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A painting device for machining mechanical parts includes a main body with a painting device mounted on it. A flange inner support fixing member is fixedly connected to the upper side of the main body. The flange inner support fixing member includes a rib installed on the main body. A top block is fixedly connected to the top of the rib. Multiple support arms are rotatably connected to the periphery of the top block. A sliding sleeve is vertically slidably connected to the outer side of the rib. Multiple diagonal braces, each corresponding to a support arm, are rotatably connected to the outer side of the sliding sleeve. The other end of each diagonal brace is rotatably connected to a support arm. An elastic reset frame is fixedly connected to the outer side of the rib and below the sliding sleeve.

[0007] Furthermore, the elastic reset frame includes a limiting plate fixedly connected to the outside of the rib, and a return spring fixedly connected to the upper side of the limiting plate, with the upper end of the return spring fixedly connected to the sliding sleeve.

[0008] Furthermore, one end of the support arm is rotatably connected to a side plate, and the lower end of the side plate is fixedly connected to a base plate.

[0009] Furthermore, a tension spring is provided between the upper end of the side plate and the support arm, with one end of the tension spring rotatably connected to the side plate and the other end of the tension spring rotatably connected to the support arm.

[0010] Furthermore, the support arm includes a first support rod rotatably connected to the side of the top block, one end of the diagonal brace is rotatably connected to the first support rod, a second support rod is slidably connected inside the first support rod, one end of the second support rod is rotatably connected to the side plate, and a locking screw is threaded onto the first support rod.

[0011] Furthermore, a rotating sleeve is rotatably connected to the upper side of the main body of the device, the lower end of the rib is inserted into the interior of the rotating sleeve, a servo motor is fixedly connected to the upper side of the main body of the device, a worm is fixedly connected to the output end of the servo motor, and a worm wheel is fixedly connected to the outer side of the rotating sleeve, with the worm and worm wheel meshing together.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a painting device for machining mechanical parts. When installing or disassembling a flange unit, the user holds the sliding sleeve and pulls it downwards. The diagonal brace pulls the support arm downwards and rotates it, causing the combination of multiple support arms to retract. This reduces the horizontal cross-sectional dimension of the flange inner support fixing part, making it easier to fit the flange unit onto the outside of the flange inner support fixing part or to remove the flange unit from the outside of the flange inner support fixing part. This simplifies the installation or disassembly of the flange unit and facilitates the painting process of the flange unit. Attached Figure Description

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-4 As shown, a painting device for machining mechanical parts includes a main body 1 and a painting device 2 mounted on the main body 1. The painting device 2 is used to paint the mechanical parts. The painting device 2 can include a robotic arm fixedly connected to the main body 1, with a spray gun mounted on the robotic arm. Paint is sprayed through the spray gun. The painting device 2 can also be a handheld spray gun or other painting equipment, as long as it can paint the mechanical parts. This is a mature existing technology, and this technical solution will not be described in detail.

[0022] In this technical solution, the mechanical component is specifically the flange unit 19. In order to position the flange unit 19, a flange inner support fastener is also fixedly connected to the upper side of the main body 1 of the device. This fastener is used to fix and limit the flange unit 19 from inside the flange unit 19, so that the peripheral side of the flange unit 19 can be fully exposed and receive the coating.

[0023] Here, the main body 1 of the device can be a base, a conveyor belt, or other moving mechanism that can move the flange inner support fixing parts.

[0024] The core of this technical solution lies in the improvement of the structure of the flange internal support fastener, specifically as follows: Figures 1-4 As shown, the flange inner support fastener includes a rib 7 installed on the main body 1 of the device. The installation method can be a plug-in or snap-fit ​​connection. A top block is fixedly connected to the top of the rib 7. Multiple support arms are rotatably connected to the periphery of the top block. A sliding sleeve 10 is vertically slidably connected to the outer side of the rib 7. Multiple diagonal braces 18, which are one-to-one with the support arms, are rotatably connected to the outer side of the sliding sleeve 10. The other end of the diagonal brace 18 is rotatably connected to the support arm. At this time, the support arm can be rotated by sliding the sliding sleeve 10 up and down through the diagonal brace 18.

[0025] An elastic reset frame is fixedly connected to the outer side of the rib 7 and the lower side of the sliding sleeve 10. This frame is used to drive the sliding sleeve 10 to elastically reset upwards. When installing or removing the flange unit 19, the user holds the sliding sleeve 10 and pulls it downwards. The support arm is pulled downwards and rotated by the diagonal brace 18, causing the combination of multiple support arms to retract. This reduces the horizontal cross-sectional dimension of the flange inner support fixing member, making it easier to fit the flange unit 19 onto the outside of the flange inner support fixing member or to remove the flange unit 19 from the outside of the flange inner support fixing member. This makes it easier to install or remove the flange unit 19. After the flange unit 19 is installed, the sliding sleeve 10 is released. Under the action of the elastic reset frame, the sliding sleeve 10 elastically resets upwards. When the sliding sleeve 10 resets, it drives the support arm to rotate upwards, causing the combination of multiple support arms to unfold until the support arm and the inner wall of the flange unit 19 abut against each other, thus completing the fixation of the flange unit 19.

[0026] like Figures 2-3 As shown, the elastic reset frame includes a limiting plate 8 fixedly connected to the outside of the rib 7. A return spring 9 is fixedly connected to the upper side of the limiting plate 8. The upper end of the return spring 9 is fixedly connected to the sliding sleeve 10. When the sliding sleeve 10 slides down, it will compress and store energy in the return spring 9. After the sliding sleeve 10 is released, the return spring 9 will reset the sliding sleeve 10. Its structure is relatively simple.

[0027] like Figures 2-3 As shown, one end of the support arm is rotatably connected to a side plate 14. The side plate 14 increases the contact area between the flange inner support fastener and the inner wall of the flange unit 19, thereby improving the assembly stability of the flange unit 19.

[0028] Meanwhile, the lower end of the side plate 14 is fixedly connected to the bottom plate 15, so that the side plate 14 and the bottom plate 15 form an L-shaped structure. The bottom plate 15 can limit the flange unit 19 from the bottom, reducing the downward displacement of the flange unit 19 on the outside of the flange inner support fixing member.

[0029] A tension spring 16 is provided between the upper end of the side plate 14 and the support arm. One end of the tension spring 16 is rotatably connected to the side plate 14, and the other end of the tension spring 16 is rotatably connected to the support arm. When the flange unit 19 is not assembled on the outside of the side plate 14, the tension spring 16 allows the upper end of the side plate 14 to rotate towards the axis of the rib 7. This reduces the size of the upper end of the multiple side plate 14 assembly when the flange inner support fastener retracts, making it easier for the flange unit 19 to be fitted onto the outside of the multiple side plate 14 assembly.

[0030] The support arm can be a straight plate, or it can be like... Figures 3-4As shown, the support arm includes a first support rod 11 rotatably connected to the side of the top block, one end of the diagonal brace 18 rotatably connected to the first support rod 11, and a second support rod 12 slidably connected inside the first support rod 11. One end of the second support rod 12 is rotatably connected to the side plate 14. At this time, the length of the support arm can be adjusted by sliding the second support rod 12 to adapt to flange units 19 with different inner diameters. A locking screw 13 is threaded on the first support rod 11. After the second support rod 12 has slid, the locking screw 13 can be rotated to make the locking screw 13 abut against the second support rod 12 to lock the position of the second support rod 12.

[0031] Multiple limiting blocks 17 located on the upper side of the support arm are also fixedly connected to the periphery of the top block. The supporting arm can be uppered by setting the limiting blocks 17.

[0032] like Figures 1-2 As shown, one installation method of the prism bar 7 is disclosed here. A rotating sleeve 3 is rotatably connected to the upper side of the device body 1. The lower end of the prism bar 7 is inserted into the interior of the rotating sleeve 3. A servo motor 4 is also fixedly connected to the upper side of the device body 1. A worm 5 is fixedly connected to the output end of the servo motor 4. A worm wheel 6 is fixedly connected to the outer side of the rotating sleeve 3. The worm 5 and the worm wheel 6 are meshed. By starting the servo motor 4, the worm 5 can be driven to rotate. When the worm 5 is started, it will push the worm wheel 6, inputting rotational kinetic energy into the rotating sleeve 3, which will drive the flange unit 19 on the prism bar 7 to rotate, so that the painting equipment 2 can perform painting treatment on the flange unit 19.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
