Description

Technical Field

[0001] This invention relates to the field of spray painting technology, and in particular to a spray painting equipment for the production of self-cooling speed reducers. Background Technology

[0002] A self-cooled speed reducer is a type of speed reducer with a self-cooling function. It reduces the speed and increases the torque between the prime mover and the driven machine. At the same time, it can effectively dissipate heat through its own cooling structure to ensure stable operation of the equipment. The working principle of a self-cooled speed reducer is the same as that of an ordinary speed reducer. Both use transmission components such as gears and worm gears to convert the high speed of the prime mover into a low speed while increasing the torque.

[0003] When painting some speed reducers, it is necessary to cover and protect the left mounting end face, left rotating shaft, right mounting end face, and right rotating shaft of the speed reducer to prevent these areas from being painted and affecting subsequent installation and use. However, the existing painting equipment is not convenient for covering and protecting the left mounting end face, left rotating shaft, right mounting end face, and right rotating shaft of the speed reducer.

[0015] The beneficial effects of this invention are: 1. In use, the reducer body to be painted is placed on the movable base. During the placement of the reducer body, the positioning mechanism is used to position the reducer body. After the reducer body is placed, the left and right movable arms move closer together under the action of the first linkage component. During this process, the left movable arm moves closer to the reducer body with the left sleeve and the left abutment plate until the left sleeve is fitted onto the outer surface of the left rotating shaft and the left abutment plate abuts against one side of the left mounting end face. During this process, the right movable arm moves closer to the reducer body with the right sleeve and the right abutment plate until the right sleeve is fitted onto the outer surface of the right rotating shaft and the right abutment plate abuts against one side of the right mounting end face. As the left and right movable arms move closer together, the two positioning mechanisms move away from each other under the action of the second and third linkage components to avoid affecting the painting process on the outer surface of the reducer body chassis. Then, the movable base carries the reducer body into the paint spraying chamber, where the outer surface of the reducer body is painted by the spraying mechanism. This method is convenient to use.

[0016] 2. When the left moving arm moves closer to the reducer body, it will drive the left slider one and the left rack one to move together, thereby pushing the left gear to rotate. The rotating left gear drives the left rack two, the left slider two, the left L-shaped connecting block and the corresponding L-shaped positioning block away from the reducer body, which is convenient to use.

[0017] 3. After the electric load-bearing slider, carrying the moving seat and the reducer body, enters the paint spraying chamber, the opening and closing door is closed. The reducer body is then painted by the set spraying mechanism. The paint mist generated during the painting process is adsorbed by the set filter components to avoid pollution to the working environment. Attached Figure Description

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Reference Figures 1-12 A painting device for producing self-cooled speed reducers includes a workbench 100 and a paint spraying chamber 101. One end of the workbench 100 extends into the paint spraying chamber 101. A spraying mechanism is installed inside the paint spraying chamber 101. The spraying mechanism is existing technology. A movable base 102 is movably mounted on the workbench 100. A left movable arm 103 and a right movable arm 104 are movably mounted on both sides of the movable base 102, respectively. A left sleeve 105 is fixed to the side wall of the left movable arm 103. The outer surface of the left sleeve 105... A left-side contact plate 106 is fixedly sleeved, and a right-side sleeve 107 is fixedly sleeved on the side wall of the right-side moving arm 104. A right-side contact plate 108 is fixedly sleeved on the outer surface of the right-side sleeve 107. A linkage component one is provided between the left-side moving arm 103 and the right-side moving arm 104. Two positioning mechanisms are provided on the moving base 102 for cooperative use. A linkage component two is provided between the left-side moving arm 103 and the adjacent positioning mechanism, and a linkage component three is provided between the right-side moving arm 104 and the adjacent positioning mechanism.

[0022] In the initial state, the movable seat 102 is located away from the paint spray chamber 101, and the left movable arm 103 and the right movable arm 104 are in a state of being far apart from each other.

[0023] The reducer body 900 is provided with a left mounting end face 901, a left rotating shaft 902, a right mounting end face 903, and a right rotating shaft 904.

[0024] In use, the reducer body 900 to be painted is placed on the movable base 102. During the placement of the reducer body 900, the positioning mechanism positions the reducer body 900. After the reducer body 900 is placed, the linkage component 1 causes the left movable arm 103 and the right movable arm 104 to move closer to each other. During this process, the left movable arm 103, along with the left sleeve 105 and the left abutment plate 106, moves closer to the reducer body 900 until the left sleeve 105 is fitted onto the outer surface of the left rotating shaft 902, and the left abutment plate 106 abuts against one side of the left mounting end face 901. During this process, the right... The moving arm 104, carrying the right sleeve 107 and the right contact plate 108, moves closer to the reducer body 900 until the right sleeve 107 is fitted onto the outer surface of the right rotating shaft 904 and the right contact plate 108 abuts against one side of the right mounting end face 903. As the left moving arm 103 and the right moving arm 104 approach each other, under the action of the linkage component two and linkage component three, the two positioning mechanisms are moved away from each other to avoid affecting the painting process on the outer surface of the reducer body 900 chassis. Then the moving seat 102 carries the reducer body 900 into the paint spraying chamber 101, where the outer surface of the reducer body 900 is painted by the set spraying mechanism, which is convenient to use.

[0025] After the painting process is completed, the moving seat 102 moves the reducer body 900 away from the paint spray chamber 101. Then, under the action of the linkage component one, the left moving arm 103 and the right moving arm 104 are moved away from each other, thereby moving the left sleeve 105, the left contact plate 106, the right sleeve 107 and the right contact plate 108 away from the reducer body 900. This allows the painted reducer body 900 to be unloaded. In the process of the left moving arm 103 and the right moving arm 104 moving away from each other, the two positioning mechanisms are moved and reset, ready to position the next reducer body 900 to be painted.

[0026] It should be noted that since both the left sleeve 105 and the right sleeve 107 have a certain length, during the painting process, the left moving arm 103 and the right moving arm 104 are at a large distance from the reducer body 900, which will not hinder the operation of the painting mechanism.

[0027] Each positioning mechanism includes an L-shaped positioning block 200 movably mounted on a movable seat 102. A guide rod 201 is fixed to one side of the L-shaped positioning block 200, and a guide seat 202 is fixed to the upper surface of the movable seat 102. One end of the guide rod 201 movably passes through the guide seat 202.

[0028] In use, the two L-shaped positioning blocks 200 work together to position the reducer body 900.

[0029] The L-shaped positioning block 200 is guided by the cooperation of the guide rod 201 and the guide seat 202.

[0030] The second linkage component includes a left slide groove 300 on one side of the movable base 102. A left gear 301 is rotatably installed at the bottom of the left slide groove 300. A left slider 1 302 and a left slider 2 303 are installed in the left slide groove 300. The left slider 1 302 and the left slider 2 303 are symmetrically arranged about the center of the left gear 301. One end of the left slider 1 302 is fixedly connected to the left movable arm 103. A left rack 1 304 is fixed to one side of the left slider 1 302. A left rack 2 305 is fixed to one side of the left slider 2 303. Both the left rack 1 304 and the left rack 2 305 are meshed with the left gear 301. A left L-shaped connecting block 306 is fixed to one end of the left slider 2 303. One end of the left L-shaped connecting block 306 is fixedly connected to the adjacent L-shaped positioning block 200.

[0031] When the left movable arm 103 moves closer to the reducer body 900, it will drive the left slider 302 and the left rack 304 to move together, thereby pushing the left gear 301 to rotate. The rotating left gear 301 drives the left rack 305, the left slider 303, the left L-shaped connecting block 306 and the corresponding L-shaped positioning block 200 away from the reducer body 900.

[0032] The linkage component three includes a right side slide groove 400 located on the other side of the movable base 102. A right side gear 401 is rotatably mounted on the bottom of the right side slide groove 400. A right side slider 1 402 and a right side slider 2 403 are slidably mounted inside the right side slide groove 400. The right side slider 1 402 and the right side slider 2 403 are symmetrically arranged about the center of the right side gear 401. One end of the right side slider 1 402 is fixedly connected to the right movable arm 104. A right side rack 1 404 is fixedly mounted on one side of the right side slider 1 402. A right side rack 2 405 is fixedly mounted on one side of the right side slider 2 403. Both the right side rack 1 404 and the right side rack 2 405 are meshed with the right side gear 401. A right side L-shaped connecting block 406 is fixedly mounted on one end of the right side slider 2 403. One end of the right side L-shaped connecting block 406 is fixedly connected to the adjacent L-shaped positioning block 200.

[0033] When the right movable arm 104 moves closer to the reducer body 900, it will drive the right slider 402 and the right rack 404 to move, thereby pushing the right gear 401 to rotate. The rotating right gear 401 drives the right rack 405, the right slider 403, the right L-shaped connecting block 406 and the corresponding L-shaped positioning block 200 away from the reducer body 900.

[0034] The linkage component includes a cavity 500 formed within the movable base 102. A vertical rotating column 501 is rotatably mounted at the bottom of the cavity 500. A gear ring 502 is fixedly fitted on the outer surface of the vertical rotating column 501 near its upper end. A left sliding seat 503 and a right sliding seat 504 are slidably mounted within the cavity 500. The left sliding seat 503 and the right sliding seat 504 are symmetrically arranged about the center of the vertical rotating column 501. One end of the left sliding seat 503 movably passes through the movable base 102 and is fixedly connected to the left movable arm 103. One end of the right sliding seat 504 movably passes through the movable base 102 and is fixedly connected to the right movable arm 104. An internal rack 505 is fixedly mounted on one side of the left sliding seat 503, and an internal rack 506 is fixedly mounted on one side of the right sliding seat 504. Both the internal rack 505 and the internal rack 506 are meshed with the gear ring 502. A drive unit that works in conjunction with the vertical rotating column 501 is provided on the movable base 102.

[0035] When the drive unit drives the vertical rotating column 501 and the gear ring 502 to rotate in opposite directions, it will drive the internal rack 1 505 and the internal rack 2 506 to move away from each other, thereby causing the left sliding seat 503 and the right sliding seat 504 to move away from each other, thereby driving the left moving arm 103 and the right moving arm 104 to move away from each other.

[0036] When the drive unit drives the vertical rotating column 501 and the gear ring 502 to rotate in the forward direction, it will drive the left movable arm 103 and the right movable arm 104 to move closer to each other.

[0037] The drive unit includes a cavity 2 opened in the movable seat 102. The lower end of the vertical rotating column 501 rotatably passes through the cavity 2 and is fixedly fitted with a worm gear sleeve 600. A horizontal rotating column 601 is rotatably arranged in the cavity 2. A worm sleeve 602 is fixedly fitted on the outer surface of the horizontal rotating column 601. The worm sleeve 602 is meshed with the worm gear sleeve 600. One end of the horizontal rotating column 601 rotatably passes through the movable seat 102 and is fixedly fitted with a handwheel 603.

[0038] When the handwheel 603 drives the horizontal rotating column 601 to rotate, it will drive the worm sleeve 602 to rotate together, thereby driving the worm gear sleeve 600, the vertical rotating column 501 and the gear ring 502 to rotate.

[0039] A door 700 is provided on one side of the paint spraying chamber 101. Two electric slide rails 701 are symmetrically fixed on the upper surface of the workbench 100. The same electric bearing slider 702 is slidably mounted on the two electric slide rails 701. The moving seat 102 is fixed to the upper surface of the electric bearing slider 702. A filter assembly is provided inside the paint spraying chamber 101.

[0040] Both the electric slide rail 701 and the electric load-bearing slider 702 are existing technologies. When the electric load-bearing slider 702, carrying the moving seat 102 and the reducer body 900, enters the paint spraying chamber 101, the opening and closing door 700 closes. The reducer body 900 is then painted by the set spraying mechanism. The paint mist generated during the painting process is adsorbed by the set filter components to avoid pollution to the working environment.

[0041] The painting mechanism includes mounting platforms 703 fixed on both sides of the workbench 100. Each mounting platform 703 is equipped with an automatic painting robot arm on its upper surface. The automatic painting robot arm is existing technology. The automatic painting robot arm is used to paint the outer surface of the reducer body 900.

[0042] The filter assembly includes an air suction hood 800 movably disposed at the top of the paint spray chamber 101. A filter layer is fixed on the inner wall of the air suction hood 800. A telescopic hose 801 is connected to one side of the air suction hood 800. One end of the telescopic hose 801 passes through the paint spray chamber 101 and is connected to an external air extraction unit. The air extraction unit is existing technology.

[0043] During the painting process, the air extraction unit works to generate airflow, thereby drawing the paint mist in the paint spraying chamber 101 into the air suction hood 800, where the paint mist in the air is adsorbed and filtered through the filter layer.

[0044] An electric guide rail 802 is fixedly installed through the upper end face of the paint spraying chamber 101, and an electric slider is slidably installed inside the electric guide rail 802. The suction hood 800 is fixed to the lower end face of the electric slider.

[0045] Both the electric guide rail 802 and the electric slider are existing technologies. By cooperating with the electric guide rail 802 and the electric slider, the suction hood 800 can be moved horizontally, thereby adjusting the position of the suction hood 800 according to the position of the painting process.

[0046] In use, the reducer body 900 to be painted is placed on the movable base 102. During the placement of the reducer body 900, the positioning mechanism positions the reducer body 900. After the reducer body 900 is placed, the linkage component 1 causes the left movable arm 103 and the right movable arm 104 to move closer to each other. During this process, the left movable arm 103, along with the left sleeve 105 and the left abutment plate 106, moves closer to the reducer body 900 until the left sleeve 105 is fitted onto the outer surface of the left rotating shaft 902, and the left abutment plate 106 abuts against one side of the left mounting end face 901. During this process, the right movable arm 104 moves closer to the reducer body 900. The boom 104 moves close to the reducer body 900 with the right sleeve 107 and the right contact plate 108 until the right sleeve 107 is fitted onto the outer surface of the right rotating shaft 904 and the right contact plate 108 abuts against one side of the right mounting end face 903. As the left moving arm 103 and the right moving arm 104 approach each other, the two positioning mechanisms are moved away from each other by the action of the linkage component two and linkage component three to avoid affecting the painting process on the outer surface of the reducer body 900 chassis. Then the moving seat 102 carries the reducer body 900 into the paint spraying chamber 101. The outer surface of the reducer body 900 is painted by the set spraying mechanism, which is convenient to use. After the painting process is completed, the moving seat 102 moves the reducer body 900 away from the paint spraying chamber 101. Then, under the action of the linkage component one, the left moving arm 103 and the right moving arm 104 are moved away from each other, thereby moving the left sleeve 105, the left contact plate 106, the right sleeve 107 and the right contact plate 108 away from the reducer body 900. This allows the painted reducer body 900 to be unloaded. In the process of the left moving arm 103 and the right moving arm 104 moving away from each other, the two positioning mechanisms are moved and reset, ready to position the next reducer body 900 to be painted. When the electric load-bearing slider 702, carrying the moving seat 102 and the reducer body 900, enters the paint spraying chamber 101, the opening and closing door 700 closes. The reducer body 900 is then painted by the set spraying mechanism. The paint mist generated during the painting process is adsorbed by the set filter components to avoid pollution to the working environment.

[0047] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
