Description

Technical Field

[0001] This utility model relates to the field of vehicle door panel processing technology, specifically to a surface painting machine for railway vehicle door panel production. Background Technology

[0002] The body of a railway vehicle mainly consists of several parts, including the roof, side walls, end walls, door panels, and underframe. During the production and processing of door panels, it is often necessary to spray paint on them to improve their surface quality, provide rust or insect protection, extend their service life, and give them a variety of surface colors to meet different needs. Usually, painting is done manually by workers. Basically, after one side is painted, the paint has to be dried before the second side is painted. Therefore, the operation time is long, and when dealing with curved door panels, the difficulty of painting increases when considering the uniformity of the paint, resulting in a significant waste of manpower. Utility Model Content

[0003] The purpose of this utility model is to provide a surface painting machine for the production of railway vehicle door panels that is reasonably designed and easy to use, in order to address the defects and shortcomings of the existing technology and effectively solve the defects of the existing technology.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a base plate, a support plate, a clamping plate, and an adjusting screw. The support plate is positioned above the base plate, and clamping plates are symmetrically positioned above the support plate. The lower side of the clamping plates is slidably mounted on the support plate via a slider. An adjusting screw is screwed into the support plate via a bearing. The threads at both ends of the adjusting screw are opposite, and one end of the adjusting screw is driven by a motor. It also includes:

[0005] The mounting boxes are four in total, and they are symmetrically arranged in pairs on the left and right sides above the base plate. The lower side of the mounting boxes is connected to the base plate through a drive mechanism.

[0006] There are two air outlet pipes, which are respectively embedded on the outer wall of one side of the mounting box, which is set diagonally on both sides. The nozzles on the air outlet pipes are set facing the side of the support plate.

[0007] The paint spraying pipe consists of two pipes, each embedded in the outer wall of one side of another mounting box on both sides, with the nozzles on the paint spraying pipes facing the side of the support plate.

[0008] Two pumps are provided, each connected to a paint spraying pipe. The pumps are fixed on the outer top wall of the adjacent mounting box, and the inlet of the pumps is connected to the interior of the mounting box.

[0009] Two air pumps are provided, each connected to an air outlet pipe. The air pumps are fixed on the inner bottom wall of the adjacent mounting box, and the side wall of the mounting box has several air inlets arranged in a matrix.

[0010] Heating rods, wherein there are several heating rods, and they are equally distributed and spaced above the air pump, and the heating rods are fixed to the inner wall of the mounting box;

[0011] The above technical solution involves placing the door panel on the support plate, activating the motor on the adjusting screw, which drives the adjusting screw to rotate. The adjusting screw, through the threads at both ends, moves the clamping plate towards the center until the clamping plate abuts against the door panel, thus limiting the door panel's position. Then, the drive mechanism is activated, moving the mounting box. During this movement, the paint spray pipe is positioned at the front of the forward direction. When the paint spray pipe reaches the front and rear sides of the door panel, the pump is activated, drawing paint from the mounting box into the paint spray pipe, which then sprays it out through the nozzles on the pipe, allowing for painting of the door panel. During the painting process, an air extraction pump is activated, drawing outside air into the mounting box. After being heated by a heating rod, the air enters the exhaust pipe and is sprayed onto the door panel through the nozzles on the exhaust pipe, thus simultaneously performing a drying operation and improving work efficiency.

[0012] As a further improvement of this utility model, the bottom plate has a hollow structure inside, and the front and rear sides of the upper side wall of the bottom plate are provided with feed inlets, and the front and rear side walls of the support plate are provided with through holes, which are connected to the feed inlets.

[0013] With the above technical solution, excess paint generated during the spraying process flows into the base plate through the through hole and the feed port, making it easy to reuse later.

[0014] As a further improvement of this utility model, a baffle is provided on the upper side of the adjusting screw, one side wall of the baffle is fixedly connected to the clamping plate, and the other side of the baffle is screwed to the side wall of the support plate through a coil spring and a shaft.

[0015] The above technical solution can easily cover the groove on the support plate, preventing paint from falling into the groove.

[0019] Connecting rods, there are several connecting rods, and they are arranged one-to-one between two adjacent mounting plates. The two ends of the connecting rods are inserted into the side walls of the two adjacent mounting plates and are screwed together by a shaft.

[0020] The spiral rod has two ends mounted on the base plate via bearing seats. A gear meshes with the lower side of one end of the spiral rod. The gear is connected to a drive motor, and the drive motor is fixed on the bearing seat on one side of the spiral rod.

[0021] The driving block consists of several blocks, each of which is fixed to the mounting plate by a support plate. The driving block is engaged with the screw rod.

[0022] With the above technical solution, the drive motor is started, and the drive motor drives the screw rod to rotate through the gear. The screw rod drives the drive block on it to move. During the movement of the drive block, the support plate drives the mounting plate to move. The mounting plate drives the connected mounting plate to move through the connecting rod. The mounting plate then drives the drive block on it to move, so that the next drive block can be locked onto the screw rod. Thus, through the cooperation of the connecting rods between several drive blocks and mounting plates, the mounting plate moves, and the mounting plate drives the corresponding mounting box to move.

[0023] As a further improvement of this utility model, a filter screen is provided on the outer side of the air inlet, and the filter screen is fixed on the outer side wall of the mounting box.

[0024] The above technical solution can filter the gas entering the installation box.

[0025] As a further improvement of this utility model, guide frames are fixed on both the front and rear sides of the upper surface of the support plate. The guide frames are arranged in an inverted "L" shape. The horizontal plate of the guide frame is suspended on the upper side of the base plate. Baffles are fixed on both the left and right sides of the upper surface of the support plate.

[0026] The above technical solution can be used to cover up paint that falls off during the painting process.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows: The surface painting machine for railway vehicle door panel production described in this utility model can simultaneously paint both sides of the door panel and dry it at the same time, which improves work efficiency. This utility model has the advantages of reasonable setting and low manufacturing cost. Attached Figure Description
