Description

Technical Field

[0001] The technical solution relates to the technical field of motor assembly equipment, and particularly refers to a motor end cover crimping device. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (i.e., the stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magnetoelectric dynamic rotating torque. The motor mainly consists of a stator and a rotor. The direction of the force on the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic induction line (magnetic field direction). The working principle of the motor is the action of the magnetic field on the current, which causes the motor to rotate.

[0003] Currently, for the assembly of motors in the market, the stator, rotor, and end cover need to be installed inside the barrel. Among them, the wires of the stator need to pass through the end cover, which makes the automation production difficult. When actually crimping the end cover, the staff needs to ensure that the wires of the stator pass through the end cover, which increases the workload of the staff and results in low production efficiency. Summary of the Invention

[0004] The purpose of the technical solution is to provide a motor end cover crimping device, which can automatically ensure that the wiring of the stator is located in the through hole of the end cover during the process of crimping the end cover through the end cover transfer mechanism and the end cover crimping mechanism, and solve the problem of low production efficiency caused by manual operation.

[0005] The purpose of the technical solution is achieved as follows:

[0006] A motor end cover crimping device includes: a main frame; an end cover transfer mechanism, which is arranged on the main frame and is used to grab the end cover in the to-be-processed state beside the barrel and place it above the barrel; and an end cover crimping mechanism, which is arranged at the lower end of the end cover transfer mechanism and is used to crimp the end cover onto the barrel. Among them, the end cover in the to-be-processed state means that the end cover is placed beside the barrel and the wiring of the stator in the barrel passes through the through hole of the end cover. During the operation of the end cover transfer mechanism and the end cover crimping mechanism, the end cover transfer mechanism and the end cover crimping mechanism always ensure that the wiring of the stator is located in the through hole of the end cover.

[0007] Preferably, the end cover transfer mechanism includes: a displacement component, which is arranged on the main frame; a lifting component, which is arranged on the displacement component; a rotating component, which is arranged on the lifting component; and a grasping component, which is arranged on the rotating component and is used to grab the end cover. Among them, after the grasping component grabs the end cover through the cooperation of the lifting component, the displacement component, and the rotating component, the end cover is rotated and placed above the barrel.

[0008] Preferably, the displacement assembly includes: a displacement driving member disposed on the main frame; a displacement slide rail disposed on the main frame; and a displacement plate disposed at the output end of the displacement driving member and movably disposed on the displacement slide rail through a displacement slider.

[0009] Preferably, the lifting assembly includes: a lifting driving member disposed on the displacement plate; and a lifting plate disposed at the output end of the lifting driving member; wherein, the lifting plate is connected to the displacement plate through a plurality of guiding columns I.

[0010] Preferably, the rotating assembly includes: a rotating driving member disposed on the lifting plate, and a driving wheel is disposed at the output end thereof; a rotating shaft inserted through the lifting plate through a bearing; a driven wheel sleeved outside the rotating shaft; and a belt sleeved outside the driving wheel and the driven wheel.

[0011] Preferably, the grasping assembly includes: a grasping driving member disposed at the lower end of the rotating shaft; and a grasping jaw disposed at the output end of the grasping driving member.

[0012] Preferably, the end cap press-fitting mechanism includes: a mounting plate disposed on the lifting plate through a plurality of guiding columns II; a press-fitting driving member disposed on the mounting plate; a press-fitting slide rail disposed on the mounting plate; and a press-fitting portion disposed at the output end of the press-fitting driving member and movably disposed on the press-fitting slide rail through a press-fitting slider.

[0013] Preferably, the crimping device further includes an end cap supporting mechanism, which includes: an end cap supporting driving member disposed on the main frame; an end cap supporting seat disposed on the main frame; an end cap supporting movable portion disposed at the output end of the end cap supporting driving member and placed inside the end cap supporting seat; and an end cap supporting portion disposed inside the end cap supporting seat and movably abutted against the end cap supporting movable portion; wherein, the end cap supporting movable portion has a first inclined surface, and the end cap supporting portion has a second inclined surface; the end cap supporting movable portion realizes the vertical movement of the end cap supporting portion through the cooperation of horizontal movement and the first inclined surface and the second inclined surface.

[0014] The prominent and beneficial technical effects of this technical solution compared with the prior art are:

[0015] 1. This technical solution designs the end cap transfer mechanism and the end cap press-fitting mechanism to cooperate. The end cap transfer mechanism can grasp the end cap and perform rotation, horizontal and vertical movements on it, and can also drive the end cap press-fitting mechanism to move vertically to realize the press-fitting of the end cap. The output terminals of the end cap transfer mechanism and the end cap press-fitting mechanism are relatively close. Therefore, it can ensure that the wiring of the stator is located in the through hole of the end cap. The rotation action reduces the pulling distance of the stator wiring and can effectively prevent the wiring from detaching from the through hole, facilitating the automated production of the motor.

Detailed Description of the Invention

[0020] The following further details the specific implementation manners of this technical solution with reference to the drawings.

[0021] The crimping device of this application is a device used in the production of electrical equipment, which is used to press-fit the end cover onto the barrel. During the process of pressing the end cover, the initial position of the end cover is beside the barrel, the stator is inside the barrel, and the wiring of the stator passes through the through hole of the end cover. It is necessary to transfer the end cover above the barrel and then press it onto the barrel. During this process, no matter what positions the stator and the end cover are in, it is necessary to ensure that the wiring is always inside the through hole.

[0022] Such as Figure 1 and Figure 2As shown in the figure, a motor end cover crimping device includes a main frame 1, an end cover transfer mechanism 2, and an end cover transfer mechanism 2. The end cover transfer mechanism 2 is arranged on the main frame 1 and is used to grab the end cover in the to-be-processed state beside the barrel and place it above the barrel. The end cover pressing mechanism 3 is arranged at the lower end of the end cover transfer mechanism 2 and is used to press the end cover onto the barrel. The end cover transfer mechanism 2 can transfer the end cover quickly and with a large stroke. The end cover pressing mechanism 3 can finely adjust its own position through horizontal movement to press the end cover more stably. The end cover in the to-be-processed state means that the end cover is placed beside the barrel and the wiring of the stator in the barrel passes through the through hole of the end cover. During the operation of the end cover transfer mechanism 2 and the end cover pressing mechanism 3, the end cover transfer mechanism 2 and the end cover pressing mechanism 3 always ensure that the wiring of the stator is located in the through hole of the end cover.

[0023] As Figure 2 As shown in the figure, the end cover transfer mechanism 2 includes a displacement component 4, a lifting component 5, a rotating component 6, and a grasping component 7. The displacement component 4 is arranged at the top of the main frame 1 and is used to realize the horizontal movement of the grasping component 7. Part of the lifting component 5 is arranged on the displacement component 4, and part of the components pass through the displacement component 4 and extend below the displacement component 4 to realize the vertical movement of the grasping component 7. The rotating component 6 is arranged at the lower end of the lifting component 5 and is used to realize the rotation of the grasping component 7. The grasping component 7 is arranged at the lower end of the rotating component 6 and is used to grasp the end cover. After the grasping component 7 grasps the end cover through the cooperation of the lifting component 5, the displacement component 4, and the rotating component 6, the end cover is rotated and placed above the barrel.

[0024] Specifically, the displacement component 4 includes a displacement driving part 41, a displacement slide rail 42, and a displacement plate 43. The displacement driving part 41 is arranged on the main frame 1. The number of displacement slide rails 42 is set to two and is arranged on the main frame 1. The side end of the displacement plate 43 is arranged at the output end of the displacement driving part 41, and both ends are movably arranged on the two displacement slide rails 42 through displacement sliders 44 respectively. The displacement driving part 41 can be arranged in cooperation with a motor and a lead screw to accurately drive the position of the displacement plate 43.

[0025] The lifting component 5 includes a lifting driving part 51 and a lifting plate 52. The lifting driving part 51 is arranged on the displacement plate 43, and the lifting plate 52 is arranged at the output end of the lifting driving part 51. The output end of the lifting driving part 51 passes through the main frame 1. The lifting plate 52 is connected to the displacement plate 43 through a number of guide columns 53, which can increase the stability of the displacement plate 43 arranged on the main frame 1.

[0026] The rotating assembly 6 includes a rotation driving member 61, a driving pulley 62, a rotating shaft 63, a driven pulley 64 and a belt. The rotation driving member 61 is arranged on the lifting plate 52, and the driving pulley 62 is arranged at the output end thereof. The rotating shaft 63 is inserted through the lifting plate 52 by means of a bearing. The driven pulley 64 is sleeved outside the rotating shaft 63 and is located above the lifting plate 52. The belt is sleeved outside the driving pulley 62 and the driven pulley 64. When the rotation driving member 61 drives the driving pulley 62 to rotate, the driven pulley 64 and the belt move simultaneously, and the driven pulley 64 drives the rotating shaft 63 to rotate.

[0027] The grasping assembly 7 includes a grasping driving member 71 and a grasping jaw 72. The grasping driving member 71 is arranged at the lower end of the rotating shaft 63, and the grasping jaw 72 is arranged at the output end of the grasping driving member 71. The grasping jaw 72 can grasp the end cover. The rotating shaft 63 can drive the grasping driving member 71 to rotate, so as to drive the end cover to rotate.

[0028] As Figure 2 shown, the end cover pressing mechanism 3 includes a mounting plate 31, a pressing driving member 33, a pressing slide rail 34 and a pressing portion 35. The mounting plate 31 is arranged on the lifting plate 52 through a plurality of guide columns II 32. The pressing driving member 33 is arranged on the mounting plate 31. The pressing slide rail 34 is arranged on the mounting plate 31. The pressing portion 35 is arranged at the output end of the pressing driving member 33 and is movably arranged on the pressing slide rail 34 through a pressing slider 36. The pressing portion 35 can be driven by the pressing driving member 33 to move horizontally. After fine-tuning the position, the position of the pressing portion 35 can be matched with the end cover, so that the contact area with the end cover is larger, and the end cover can be pressed more stably.

[0029] Preferably, the crimping device further includes an end cover supporting mechanism 8, which includes an end cover supporting driving member 81, an end cover supporting seat 82, an end cover supporting movable portion 83 and an end cover supporting portion 84. The end cover supporting driving member 81 and the end cover supporting seat 82 are arranged on the main frame 1. The end cover supporting movable portion 83 and the end cover supporting portion 84 are movably clamped in the end cover supporting seat 82. The end cover supporting movable portion 83 is arranged at the output end of the end cover supporting driving member 81. The end cover supporting portion 84 movably abuts against the end cover supporting movable portion 83. The end cover supporting movable portion 83 has a first inclined surface, and the end cover supporting portion 84 has a second inclined surface. The end cover supporting movable portion 83 realizes the vertical movement of the end cover supporting portion 84 through the cooperation of the horizontal movement and the first inclined surface and the second inclined surface. When pressing the end cover, the end cover supporting driving member 81 works to make the end cover supporting portion 84 support the barrel upward, so as to increase the pressing effect of the end cover.
