Description

Technical Field

[0001] The invention belongs to the technical field of ventilation slot plate processing, and in particular relates to a ventilation slot plate processing device. Background Art

[0002] The stator core of the wind turbine is assembled by stacking and pressing. During the assembly process, the position of the core punching sheets and ventilation slots is required to be high. The stator and rotor core punching sheets of the motor are divided into many stacked segments. Ventilation slots with ventilation slots are placed between the core punching segments to form radial air ducts of the stator and rotor cores for heat dissipation and ventilation cooling of the cores. The ventilation slots must be spot welded on the punching sheets accurately. After each section of the core is pressed, the axial position of the ventilation slots is in a straight line to ensure that the radial air ducts are not distorted and the axial straight line transmission of the core pressing force is ensured.

[0023] See also Figure 1 As shown, the present invention is a ventilation slot plate processing device, including a workbench 1, with two ends of the workbench being a processing station and a unloading station respectively. A circular opening 110 is provided on the workbench 1 at the processing station, and a rotating table 11 is installed at the circular opening 110. In order to facilitate driving the rotating table 11 to rotate at the circular opening 110 during use, the present invention arranges a mounting bracket on the bottom side of the workbench 1, and a driving mechanism for connecting with the rotating table 11 and driving the rotating table 11 to rotate is fixed on the mounting bracket.

[0024] It can be known that, in some embodiments, the driving mechanism is composed of electrodes, or a motor, a reducer, etc.

[0025] In order to facilitate welding the ventilation slot steel 200 to one side of the ventilation slot plate punching piece 100 during processing, the present invention provides a placement groove 10 for placing the ventilation slot steel 200 on the upper surface of the rotating table 11, and then the ventilation slot steel 200 is placed in the placement groove 10 before processing, and then the ventilation slot plate punching piece 100 with a ring structure is placed on the rotating table 11, and then the upper electrode assembly and the lower electrode assembly respectively installed on the upper and lower sides of the workbench 1 are controlled to perform corresponding actions, and then the ventilation slot steel 200 is welded to one side of the ventilation slot plate punching piece 100.

[0026] On the basis of the above, in order to facilitate welding of the ventilation slot steel 200 to the corresponding position of the ventilation slot plate punching 100, when the ventilation slot plate punching 100 is placed on the rotating table 11, it is necessary to adjust the position of the ventilation slot plate punching 100 relative to the rotating table 11, that is, a positioning mechanism for positioning the ventilation slot plate punching 100 is provided on the upper surface of the rotating table 11; Figure 2The positioning mechanism includes three groups of positioning modules evenly distributed in the ventilation slot plate punching piece 100, the positioning module includes a T-shaped slide groove 111, the T-shaped slide groove 111 is equipped with an electric slider A112 that slides in the length direction of the T-shaped slide groove 111, one end of the electric slider A112 is provided with an arc block 113 that abuts against the inner circle of the ventilation slot plate punching piece 100, the top of the electric slider A112 is connected to the telescopic cylinder A12, the end of the telescopic cylinder A12 is connected to the mounting plate 121, and the end of the mounting plate 121 is connected to a clamping column 122 that presses on the upper surface of the ventilation slot plate punching piece 100. A rubber layer 123 is set; after the ventilation slot plate punch 100 is placed on the rotating table 11, the electric slider A112 is controlled to move outward along the T-shaped slide groove 111, and the arc block 113 is used to drive the ventilation slot plate punch 100 to slide on the upper surface of the rotating table 11, and the position of the ventilation slot plate punch 100 relative to the rotating table 11 is adjusted to make the two have a concentric structure; then the telescopic cylinder A12 is controlled to contract, and at this time, the rubber layer 123 of the clamping column 122 is conveniently used to press against the ventilation slot plate punch 100, thereby preventing the ventilation slot plate punch 100 from moving during the rotation of the rotating table 11.

[0027] Based on the above, in the present invention, Figure 1 and 6 In order to facilitate the loading and unloading of the ventilation slot plate punching sheet 100 during use, a pair of U-shaped frames A3 are arranged on the upper surface of the workbench 1, and a T-shaped slide rail is arranged on the bottom side of the U-shaped frame A3. Two electric sliders B31 are arranged on the T-shaped slide rail. The end of the electric slider B31 is connected to the telescopic cylinder D32, and the end of the telescopic cylinder D32 is connected to the vacuum suction cup 33; when in use, the vacuum suction cup 33 is controlled to be adsorbed on the upper surface of the ventilation slot plate punching sheet 100, and then the telescopic cylinder D32 is controlled to contract to control and drive the ventilation slot plate punching sheet 100 to move upward in the vertical direction.

[0028] In the above, in order to facilitate the control of the movement of the electric slider B31, to ensure that the ventilation slot plate punching sheet 100 is conveniently grabbed and placed on the rotating table 11, or the ventilation slot plate punching sheet 100 is grabbed from the rotating table 11 and placed in the unloading station; in the present invention, a connecting rod is connected between the two electric sliders B31 arranged on the same T-shaped slide rail, and at least the other end of the U-shaped frame A3 is provided with a distance sensor for detecting the position of an electric slider B31 on the T-shaped slide rail.

[0029] It can be understood that the ventilation channel steel 200 is in an "I"-shaped structure. At this time, in order to facilitate the placement of the ventilation channel steel 200 in the placement slot 10, in practice, the width and length of the placement slot 10 are greater than the length and width of the ventilation channel steel 200. Therefore, during processing, when the ventilation channel steel 200 is placed in the placement slot 10, the position of the ventilation channel steel 200 relative to the placement slot 10 needs to be adjusted; Figure 4-5That is, the placement slot 10 of the present invention includes a rectangular slot 101 arranged on the upper surface of the rotating table 11, and a rectangular through hole 102 is arranged on the bottom side of the rectangular slot 101; an installation cavity A103 is respectively arranged at both ends of the rectangular slot 101, and a telescopic cylinder B104 that can be extended and retracted in the horizontal direction is arranged in the installation cavity A103, and the end of the telescopic cylinder B104 is connected to a push block A105 that abuts against the end of the ventilation slot steel 200; at least two installation cavities B106 are arranged on the two inner side walls of the rectangular slot 101, and a telescopic cylinder C that can be extended and retracted in the horizontal direction is arranged in the installation cavity B106, and the end of the telescopic cylinder C is connected to a push block B107 that abuts against both sides of the ventilation slot steel 200.

[0031] The U-shaped frame A3 passes through the bottom of the U-shaped frame B2, thereby facilitating the movement of the electric slider B31.
