Description

Technical Field

[0001] This utility model relates to the field of gearbox coating technology, specifically to a surface coating device for processing subway gearboxes. Background Technology

[0002] The subway gearbox is one of the key components of a subway vehicle. Its main function is to convert the engine speed and torque into a state suitable for vehicle operation, thereby enabling operations such as acceleration, deceleration, and gear shifting. Spraying technology is a surface treatment technology widely used in industrial production. It involves atomizing paint or other materials and spraying them onto a substrate surface to form a uniform coating for protection, decoration, or functional purposes.

[0003] When using existing surface coating equipment for gearbox processing, the fixed position of the parts makes it difficult for the spray gun to spray certain areas of the parts, resulting in uneven coating thickness on the surface of the parts. This reduces the quality and efficiency of the spraying and increases the cost of the spraying material. Utility Model Content

[0004] This invention provides a surface spraying device for processing subway gearboxes, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] An embodiment of this utility model provides a surface spraying device for processing subway gearboxes, comprising:

[0007] An operating table, the surface of which is provided with a movable groove;

[0008] Support legs are fixedly installed on the lower surface of the operating table;

[0009] A spray gun is fixedly installed on the upper surface of the workbench.

[0010] A movable base is installed on the upper surface of the operating table, and the surface of the movable base has three through slots.

[0011] A clamping and rotating device is mounted on a movable base and is used for clamping and rotating parts.

[0012] The transmission device, located at the top of the operating table, is used to clamp the movement of the rotating device.

[0013] Through the above technical solution, the clamping and rotating device can clamp the parts to be sprayed, and then move the parts to the spraying hood for spraying through the transmission device. At this time, the clamping and rotating device can make the parts rotate so that they are sprayed evenly.

[0014] Furthermore, the clamping and rotating device includes a fixed column, one end of which is fixedly connected to the upper surface of the movable seat, and the other end is rotatably connected to a hollow worm gear. A worm is meshed on the surface of the worm gear. A rotating bearing is fixedly installed on the arc surface of the fixed column, and the arc surface of the rotating bearing is rotatably connected to the worm gear. A first base is fixedly installed on the upper surface of the movable seat. A first motor is fixedly installed on the arc surface of the first base. The output end of the first motor is fixedly connected to one end of the worm. The other end of the worm is rotatably connected to a first fixing block fixedly installed on the movable seat. A rotating disk is fixedly connected to the upper surface of the worm gear. A worktable is fixedly installed on the surface of the rotating disk. Two sliding grooves are formed on the surface of the worktable. A second base is fixedly installed on the surface of the worktable. A second motor is fixedly installed on the arc surface of the second base. A first threaded rod, which is disposed in the sliding groove and penetrates the surface of the worktable, is fixedly installed on the output end of the second motor. Two clamping plates are threadedly connected to the first threaded rod 512. The threads on the first threaded rod 512 are oppositely reversed threads.

[0015] Through the above technical solution, the second motor, the stop block, and the first threaded rod can move the clamping plate towards the center in the sliding groove to clamp the parts. The first motor drives the worm to rotate, and with the cooperation of the rotating bearing and the fixed column, the worm can drive the worm wheel to rotate, thereby driving the rotating disk that is fixedly connected to the worm wheel. Then the rotating disk can drive the worktable to rotate. The other end of the fixed column is fixedly connected to the moving seat, so the fixed column and the moving seat will not rotate.

[0016] Furthermore, two blocks are fixedly installed on the upper surface of the workbench, and the two blocks are symmetrically distributed on the upper surface of the workbench. Rubber pads are fixedly installed on the surfaces of the two clamping plates, and a hollow baffle is fixedly installed on the lower surface of the workbench.

[0017] Through the above technical solution, the rubber pad can better fit the surface of the part during the clamping process and protect the surface of the part from damage that may be caused by the clamping plate during the clamping process. When the part is placed on the worktable, the stop block can assist the clamping plate in the clamping work. The baffle can block the dye during the spraying process and prevent the worm gear, worm and rotating bearing from being contaminated and corroded by the dye.

[0018] Furthermore, the transmission device includes a third base, which is fixedly installed on the upper surface of the workbench. A protective block and two second fixed blocks disposed on both sides of the third base are fixedly connected to the upper surface of the workbench. A third motor is fixedly installed on the arc surface of the third base. A second threaded rod threadedly connected to the inner wall of the movable seat is fixedly connected to the output end of the third motor. One end of the second threaded rod is rotatably connected to the surface of the protective block. A limiting rod slidably connected to the inner wall of the movable seat is fixedly installed on the surface of the second fixed block. One end of the limiting rod is fixedly connected to the surface of the protective block.

[0019] With the above technical solution, when the third motor is started, it can drive the second threaded rod to rotate with the cooperation of the protective block. The moving seat can move under the restriction of the rotation of the second threaded rod and the two limit rods.

[0020] Furthermore, a number of movable wheels are fixedly installed on the lower surface of the movable seat, and the movable wheels are evenly divided into two groups and installed on both sides of the lower surface of the movable seat.

[0021] The above technical solution allows the two sets of casters located below the mobile base to assist in moving the mobile base more quickly.

[0022] The above-described solution of this utility model has at least the following beneficial effects:

[0023] This invention uses the cooperation of a second motor, a first threaded rod, a clamping plate, and a stop block to clamp the parts, and the cooperation of a first motor, a worm gear, a worm, a rotating bearing, and a fixed column to rotate the parts, so that the parts can be sprayed more evenly during the spraying process, thereby improving the spraying quality of the parts and reducing the waste of spraying material.

[0024] In this invention, the motor, in cooperation with the protective block, can drive the second threaded rod to rotate. The moving seat can move under the restriction of the rotation of the second threaded rod and the two limit rods. The two sets of moving wheels set below the moving seat can assist the moving seat to move faster. After the spraying is completed, the part can be quickly moved to remove it and then put back into the spraying work, thus improving the efficiency of the spraying work. Attached Figure Description

[0032] like Figures 1 to 4 As shown, an embodiment of this utility model provides a surface spraying device for processing subway gearboxes, including: an operating table 1, the surface of which is provided with a movable groove 11; and a support leg 2, which is fixedly installed on the lower surface of the operating table 1.

[0033] The spray hood 3 is fixedly installed on the upper surface of the operating table 1, and the surface of the spray hood 3 is equipped with a spray gun 31;

[0034] The movable base 4 is installed on the upper surface of the operating table 1, and three through slots are provided on the surface of the movable base 4.

[0035] The clamping and rotating device 5 is mounted on the movable seat 4 and is used for clamping and rotating the parts.

[0036] The transmission device 6 is located at the upper end of the operating table 1 and is used to clamp the movement of the rotating device 5.

[0037] In this embodiment of the invention, the parts to be sprayed are placed on the workbench 59, clamped by the first motor 56 and the clamping plate 513, and then moved into the spraying hood 3 by the transmission device 6. The parts are then sprayed by the spray gun 31. During the spraying process, the clamping rotating device 5 allows the parts to rotate. After the spraying is completed, the parts are moved to the other side of the spraying hood 3 by the transmission device 6 and removed. Then the spraying is performed again.

[0038] like Figures 2 to 3 As shown, the clamping and rotating device 5 includes a fixed column 51, one end of which is fixedly connected to the upper surface of the movable seat 4, and the other end is rotatably connected to a hollow worm gear 53.

The first threaded rod 512 is threadedly connected to two clamping plates 513. The threads on the first threaded rod 512 are opposite threads.

[0039] In this embodiment of the utility model, the clamping plate 513 can be moved towards the center in the sliding groove 591 to clamp the parts by the second motor 511, the stop block 514 and the first threaded rod 512. The first motor 56 drives the worm gear 55 to rotate. With the cooperation of the rotating bearing 52 and the fixed column 51, the worm gear 55 can drive the worm wheel 53 to rotate, thereby driving the rotating disk 54 fixedly connected to the worm wheel 53.

When the part is placed on the workbench 59, the stop block 514 can assist the clamping plate 513 in the clamping work. The baffle plate 515 can block the dye during the spraying process and prevent the worm gear 53, worm 55 and rotating bearing 52 from being contaminated and corroded by the dye.

[0042] like Figure 4 As shown, the transmission device 6 includes a third base 61, which is fixedly installed on the upper surface of the workbench 59. A protective block 66 and two second fixed blocks 65 are fixedly connected to the upper surface of the workbench 59.
