Description

Technical Field

[0001] The invention relates to a spraying processing technology for a turnout pad, and in particular to a surface spraying device used for producing a turnout pad. Background Art

[0002] The spraying operation of the switch pads generally adopts the powder electrostatic spraying method. The workpiece rack is placed on the spraying bracket and then pushed into the spray room for powder spraying. After the spraying is completed, subsequent processes such as drying can be carried out. However, at present, after the bracket is moved to the spray room by manual or automatic hanging conveying equipment, it is mainly sprayed manually, and the spraying efficiency is low. In order to increase the number of switch pads sprayed at one time, the more the number of suspended switch pads, the smaller the gap between adjacent switch pads, which hinders the spraying angle and affects the quality of spraying. Although reducing the number of suspended switch pads can solve the problem, it also reduces the efficiency of spraying treatment and requires more brackets for transportation, which affects the overall production efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide a surface spraying device for the production of turnout pads to solve the above-mentioned deficiencies in the prior art.

[0005] Further, after the sliding seat moves from the first position to the second position, the rotating member drives the rotating shaft to rotate 90 degrees around its central axis.

[0006] Furthermore, during the movement of the sliding seat from the first position to the second position, the rotating member synchronously drives the rotating shaft to rotate 90 degrees around its central axis.

[0007] Furthermore, the rotating member includes a driving block slidably mounted on the rotating shaft, the inner wall of one end of the driving block is slidably connected to a guide rod, the guide rod is fixedly connected to the sliding seat, a threaded groove is provided on the rotating shaft, a pin slidably connected to the threaded groove is installed in the driving block, and the driving block is connected to a driving member A for driving it to move along the axial direction of the rotating shaft.

[0008] Furthermore, the A driving member includes a driving plate, which is fixedly mounted on one side of the driving disc through a U-shaped bracket. A guide groove is provided on the driving plate, and a guide column is fixedly connected to the driving block. When the sliding seat moves to the second position, the guide column can enter the guide groove and slide along the guide groove to move the driving block upward or downward.

[0009] Further, the two driving plates are arranged in opposite directions so that the two guide grooves are arranged in opposite directions.

[0010] Furthermore, a limiting member is arranged between the guide rod and the driving block, and the limiting member includes a limiting ball and a spherical groove opened in the middle of the guide rod and adapted to the limiting ball, the depth of the spherical groove is smaller than the radius of the limiting ball, and an active cavity for the limiting ball to move is opened in the driving block, and a first spring is arranged in the active cavity, and the elastic force of the first spring acts on the limiting ball so that the limiting ball has a tendency to move toward the direction of the guide rod.

[0012] Compared with the prior art, the surface spraying equipment for turnout pad production provided by the present invention has the following beneficial effects: The surface spraying equipment for the production of turnout pads, through the setting of the suspension components, enables each turnout pad to be distributed in a circular array for transportation. When the turnout pads are suspended, the plate surface is distributed along the radial direction of the circular hanging platform, so that the number of turnout pads that can be suspended is increased, and the space occupied by each turnout pad during transportation is reduced, thereby improving the space utilization rate. In addition, through the setting of the moving parts and the rotating parts, the spraying mechanism can spray each turnout pad in turn, without the need for manual handling or adjustment of the position of the turnout pad, thereby improving the spraying efficiency. By coordinating the moving parts and the rotating parts, the coordination time of the rotating parts and the moving parts is reduced, and the time required for the turnout pad to move to a state where the plate surface is perpendicular to the radial plane of the annular hanging platform is shortened. There is no need to wait for the sliding seat to be fully in place before starting the rotating parts, which shortens the time for adjusting the turnout pad's posture and reduces possible pauses or delays in the operation of the equipment, further improving the equipment's operating smoothness and production efficiency.

[0016] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0017] For examples, see Figure 1 - Figure 7 , a surface spraying device for the production of a turnout pad 6, comprising a spraying room (not shown) and a suspension conveying mechanism (not shown), and also comprising a suspension assembly, the suspension assembly comprising a suspension column 1, an annular hanging platform 2, a moving part 3 and a rotating part 4, the annular hanging platform 2 is provided with a plurality of slide grooves 21 distributed in an annular array along its radial direction, a sliding seat 22 is slidably connected in the slide groove 21, a rotating shaft 23 arranged in a vertical direction is rotatably connected to the inner wall of the sliding seat 22, a hanger 5 is fixedly installed below the rotating shaft 23, the hanger 5 is used to connect the turnout pad 6, the sliding seat 22 is initially located at a first position close to the center of the annular hanging platform 2, and the plate surface of the turnout pad 6 is parallel to the radial plane of the annular hanging platform 2; Two moving parts 3 are provided and installed on the suspension column 1. The annular hanging platform 2 can rotate around the suspension column 1 so that each sliding seat 22 rotates in sequence to a state of being connected with the moving part 3. The moving part 3 is used to drive the connected sliding seat 22 to move along the slide groove 21 to a second position away from the center of the annular hanging platform 2, and drive the rotating shaft 23 to rotate through the rotating part 4 so that the plate surface of the switch pad 6 is perpendicular to the radial plane of the annular hanging platform 2, wherein the plate surfaces of the switch pad 6 located at the two moving parts 3 face oppositely, and a spraying mechanism (not shown in the figure) for spraying the switch pad 6 at the second position is provided in the spraying room; It should be noted that the spray heads of the spray mechanism are arranged at positions corresponding to the two moving parts 3. When the moving part 3 drives the turnout pad 6 to rotate until its plate surface is perpendicular to the radial plane of the annular hanging platform 2, the spray heads spray the plate surface. Since the plate surfaces of the turnout pads 6 at the two moving parts 3 are opposite, the two sides of the pads will be sprayed during the spraying operation. By arranging multiple spray heads and arranging them at multiple angles, each side of the pad can be sprayed. By setting the suspension assembly, each turnout pad 6 is transported in a circular array distribution, such as Figure 1 As shown, when the switch pad 6 is suspended, the plate surface is distributed radially along the annular hanging platform 2, so that the number of switch pads 6 that can be suspended is increased while the space occupied by each switch pad 6 during transportation is smaller, thereby improving space utilization. In addition, through the arrangement of the moving part 3 and the rotating part 4, the spraying mechanism can spray each switch pad 6 in turn without manual handling or adjustment of the position of the switch pad 6, thereby improving the spraying efficiency.

[0018] During specific implementation, the hanging conveying mechanism carries the hanging assembly to the spraying room, the nozzle of the spraying mechanism is located at the position corresponding to the two moving parts 3, the annular hanging platform 2 rotates intermittently, and each time it rotates one unit, one unit is the angle corresponding to two adjacent switch pads 6, when it rotates one unit, the switch pad 6 corresponding to the two moving parts 3 moves outward and rotates so that one plate surface of the switch pad 6 faces the nozzle, and the annular hanging platform 2 continues to rotate an angle after spraying; in this process, for the same switch pad 6, it moves at the positions corresponding to the two moving parts 3 respectively, and makes its two plate surfaces correspond to the spraying mechanism respectively, thereby completing the spraying, when all the switch pads 6 on a hanging assembly have been sprayed, the hanging assembly can be moved out of the spraying room through the hanging conveying mechanism.

[0019] In one embodiment of the present invention, the intermittent rotation mode of the annular hanging platform 2 is a general groove wheel mechanism or a dividing rotation mechanism or a stepping motor. The driven groove wheel of the groove wheel mechanism has a plurality of adaptive grooves and intermittently rotates under the drive of the active dial. The output shaft of the driven groove wheel is connected to the annular hanging platform 2, and the input end is connected to the motor; the dividing rotation mechanism mainly uses a dividing plate to perform intermittent rotation. The above are all existing technologies, so they are not described in detail in this technical solution, and based on the fact that it will not cause trouble to the technical solution in this field, the specific structure is not shown in the figure.

[0020] In one embodiment of the present invention, the moving member 3 includes a driving disc 31, which is fixedly mounted on the top of the suspension column 1. A driving groove 32 is provided at the bottom of the driving disc 31. The driving groove 32 is composed of two arc grooves and two convex grooves protruding outward. One end of the sliding seat 22 close to the center of the annular hanging platform 2 is fixedly connected to a sliding column 33, and one end of each sliding column 33 is slidably connected to the driving groove 32. like Figure 4 As shown, when the annular hanging platform 2 rotates, each slide post 33 moves in the driving groove 32. When the slide post 33 moves in the arc groove of the driving groove 32, the sliding seat 22 is always in the first position. When the slide post 33 moves in the convex groove of the driving groove 32, the sliding seat 22 will move to the second position under the movement of the slide post 33, completing the movement of the moving member 3 to the turnout pad 6. In one embodiment of the present invention, a matching mode of a moving member 3 and a rotating member 4 is provided. After the sliding seat 22 moves from the first position to the second position, the rotating member 4 drives the rotating shaft 23 to rotate 90 degrees around its central axis. It should be noted that when the sliding seat 22 moves to the second position, when the switch pad 6 below the sliding seat 22 rotates under the drive of the rotating member 4, two adjacent switch pads 6 are located outside the range swept by the rotation of the switch pad 6. In one embodiment of the present invention, a specific example of a rotating part 4 is provided (not shown in the figure), which is a pneumatic motor, an electric motor or a hydraulic motor, the output end of the pneumatic motor, the output end of the electric motor or the output end of the hydraulic motor is connected to the rotating shaft 23, the housing of the pneumatic motor, the housing of the electric motor or the housing of the hydraulic motor is fixed on the sliding seat 22 through a housing mounting frame, and the rotating shaft 23 is driven by the pneumatic motor, the electric motor or the hydraulic motor to rotate so that the turnout pad 6 rotates, thereby cooperating with the moving part to complete the work; as needed, the motor can be forward or reverse to ensure that the rotation direction of the turnout pad 6 meets specific process requirements, and by controlling the rotation angle of the rotating shaft 23, the precise adjustment of the position of the turnout pad can be achieved. It should be noted that this method is a prior art and will not be described or illustrated in detail here, and based on the field, it will not cause trouble to this technical solution.

[0021] In one embodiment of the present invention, another coordination mode of the movable member 3 and the rotating member 4 is provided. In the process of the sliding seat 22 moving from the first position to the second position, the rotating member 4 synchronously drives the rotating shaft 23 to rotate 90 degrees around its central axis. Compared with the previous mode, this mode can reduce the coordination time of the rotating member 4 and the movable member 3, and shorten the time required for the turnout pad 6 to move to a state where the plate surface is perpendicular to the radial plane of the annular hanging platform 2. Specifically, when the sliding seat 22 starts to move from the first position to the second position, the rotating member 4 starts to drive the rotating shaft 23 to rotate until the sliding seat 22 completely reaches the second position, and the rotating shaft 23 also rotates 90 degrees, so that the turnout pad 6 rotates to the desired position. In this process, the movement and rotation actions are carried out synchronously, and there is no need to wait for the sliding seat 22 to be fully in place before starting the rotating member 4, which shortens the time for adjusting the posture of the turnout pad 6, reduces the pauses or delays that may occur during the operation of the equipment, and further improves the operation smoothness and production efficiency of the equipment.

[0022] In one embodiment of the present invention, another specific example of a rotating member 4 is provided, the rotating member 4 includes a driving block 41 slidably mounted on the rotating shaft 23, a guide rod 42 is slidably connected to the inner wall of one end of the driving block 41, the guide rod 42 is fixedly connected to the sliding seat 22, a thread groove 43 is provided on the rotating shaft 23, a pin slidably connected to the thread groove 43 is installed in the driving block 41, and the driving block 41 is connected to a driving member A for driving it to move along the axial direction of the rotating shaft 23; In one embodiment of the present invention, the A driving member includes a driving plate 44, which is fixedly mounted on one side of the driving disc 31 through a U-shaped bracket 45, and a guide groove 46 is formed on the driving plate 44. A guide post 47 is fixedly connected to the driving block 41. When the sliding seat 22 moves to the second position, the guide post 47 can enter the guide groove 46 and slide along the guide groove 46 to move the driving block 41 upward or downward; like Figure 3 As shown, when the sliding seat 22 moves from the first position to the second position, the guide column 47 enters the guide groove 46 and moves along the guide groove 46. Taking the driving plate 44 with the guide groove 46 tilted downward as an example, the driving block 41 will move downward and drive the rotating shaft 23 to rotate. Due to the influence of the two adjacent switch pads 6, during the movement of the sliding seat 22, the angle of rotation required for the rotating shaft 23 is not the same at the same moving distance, and the shape of the guide groove 46 determines the rotation angle of the rotating shaft 23 (this is because the moving distance of the driving block 41 determines the rotation angle of the rotating shaft 23). Therefore, for the guide groove 46, its curvature radius from one end close to the center of the annular hanging platform 2 to the other end gradually decreases, that is, the curvature degree of the guide groove 46 gradually increases. Correspondingly, when the driving block 41 moves along the slide groove 21, its rotation angle gradually increases when moving the same unit distance, and finally rotates to a state where the plate surface of the switch pad 6 is perpendicular to the radial plane of the annular hanging platform 2; as shown in FIG. Figure 1 shown.

[0023] In one embodiment of the present invention, the two drive plates 44 are set in opposite directions so that the two guide grooves 46 are in opposite directions. At this time, the drive block 41 moves upward and downward respectively with the cooperation of the two drive plates 44. When the drive block 41 moves upward, the rotating shaft 23 rotates 90 degrees in the opposite direction. That is to say, for the same turnout pad 6, when it moves at the two moving parts 3, the rotation direction of the rotating part 4 will be opposite, so that its two plate surfaces are respectively facing outward, so that a comprehensive spraying operation can be carried out under the action of the spraying mechanism.

[0024] Since the driving block 41 is in an unrestricted state when it is outside the two moving parts 3, although the guide rod 42 and the threaded groove 43 and the pin of the rotating shaft 23 can also provide a certain limiting effect, so that the driving block 41 can be kept in the middle position of the rotating shaft 23, when the switch pad 6 shakes or is shaken by external environmental factors, it is easy to cause the rotating shaft 23 to rotate to a certain extent, which will cause a certain deviation in the height of the driving block 41, thereby affecting the position of the guide column 47, resulting in the guide column 47 being unable to move into the guide groove 46. In one embodiment of the present invention, In the example, a method for solving the above problem is provided. Specifically, a limiting member 7 is provided between the guide rod 42 and the driving block 41. The limiting member 7 includes a limiting ball 71 and a spherical groove 72 provided in the middle of the guide rod 42 and adapted to the limiting ball 71. The depth of the spherical groove 72 is less than the radius of the limiting ball 71. An active cavity 73 for the limiting ball 71 to move is provided in the driving block 41. A first spring 74 is provided in the active cavity 73. The elastic force of the first spring 74 acts on the limiting ball 71 so that the limiting ball 71 has a tendency to move toward the guide rod 42. When the limiting ball 71 is located in the spherical groove 72, the driving block 41 is limited. When the driving block 41 needs to move with the cooperation of the guide column 47 and the guide groove 46, the limiting ball 71 compresses the first spring 74 to release the limit, so that the driving block 41 can move up and down. When the driving block 41 returns, the limiting ball 71 moves into the spherical groove 72 again to limit the driving block 41, so that the driving block 41 can be maintained in the middle position of the rotating shaft 23 when moving outside the moving part 3, thereby effectively preventing the rotating shaft 23 from rotating due to the shaking of the turnout pad 6 or external environmental factors, and avoiding the problem of height deviation of the driving block 41. In addition, the matching design of the limiting ball 71 and the spherical groove 72 not only improves the stability and reliability of the limit, but also makes the limit operation more flexible and convenient, ensuring that the guide column 47 can be smoothly moved into the guide groove 46, thereby improving the operating efficiency and stability of the entire equipment.

[0025] In one embodiment of the present invention, a rotating shaft 24 is rotatably connected to the surface of the suspension column 1, the top of the rotating shaft 24 is fixedly connected to the bottom of the annular hanging platform 2, and the bottom of the rotating shaft 24 is connected to a driving mechanism 8 for driving the rotation thereof; In one embodiment of the present invention, a specific example of a driving mechanism 8 is provided, the driving mechanism 8 is installed at the bottom of the rotating shaft 24 (not shown in the figure), the driving mechanism 8 includes a motor fixed to the bottom of the suspension column 1, the output end of the motor is connected to the reducer, the output end of the reducer is connected to the first gear, the first gear is meshed and connected with the second gear, the second gear is sleeved and fixed on the surface of the rotating shaft 24, the rotating shaft 24 is driven to rotate by the rotation of the motor, so that the rotating shaft 24 drives the annular hanging platform 2 to rotate a certain angle, and the intermittent rotation of the annular hanging platform 2 is completed. The advantage of the driving mechanism 8 is that each hanging component needs to be installed with a driving mechanism 8, and when the hanging conveying mechanism conveys each hanging component into the spraying room in turn, they can run separately without interfering with each other; In one embodiment of the present invention, another specific example of the driving mechanism 8 is provided, such as Figure 1 As shown, it includes a base 81 installed at the bottom of the suspension column 1, a fixed plug rod 82 is arranged at the bottom thereof, and a slot 83 adapted to the fixed plug rod 82 is arranged on the floor of the spraying room. For example, the base 81 is cross-shaped, and each fixed plug rod 82 is installed at the end of the cross-shaped base 81. When the suspension conveying mechanism conveys the suspension assembly to the spraying room, the suspension assembly is released to the ground, and the fixed plug rod 82 enters the slot 83 for position limitation; The driving mechanism 8 also includes a first bevel gear 84 mounted on the floor of the spraying room. One side of the first bevel gear 84 is connected to the motor. The bottom of the rotating shaft 24 is fixedly connected to a second bevel gear 85. When the fixed plug 82 enters the slot 83, the first bevel gear 84 meshes with the second bevel gear 85. Figure 7As shown, further, in order to ensure the stability and accuracy of the first bevel gear 84 and the second bevel gear 85 when they are engaged or disengaged, the first bevel gear 84 can also be installed on a sliding push rod 87, which is sleeved on the output shaft of the motor and can slide along its surface. A push plate is rotatably connected to the surface of the sliding push rod 87, and the push plate is connected to the output end of the electric telescopic rod 86, as shown in FIG. Figure 7 As shown, when the second bevel gear 85 reaches the position, the electric telescopic rod 86 pushes the push plate to move and drives the sliding push rod 87 to move, so that the first bevel gear 84 at the end of the sliding push rod 87 moves toward the direction close to the second bevel gear 85 and finally engages with it. After engagement, the sliding push rod 87 is driven to rotate by starting the motor to drive the first bevel gear 84 to rotate, so that the rotating shaft 24 drives the annular hanging platform 2 to rotate.

[0026] In one embodiment of the present invention, the suspension assembly can also be installed on a freely movable cart and moved into the spraying room manually.

[0027] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the present invention.
