Embodiment 1

[0044] Such as figure 1 As shown, the motor iron core riveting device is generally composed of a conveying mechanism for conveying the iron core 1 and a pressing mechanism for pressing the rivets 37 into the iron core 1 .

[0045] in,

[0046] The conveying mechanism includes a driving mechanism, a frame 2, a motor one 3 fixed on the frame 2, and a turntable 4 horizontally arranged on the frame 2 and driven by the motor one 3 to rotate. A riveting station 4a, a feeding station 4b, and a discharging station 4c are evenly distributed on the turntable 4 in sequence, wherein a pressing mechanism for pressing the rivet 37 into the iron core 1 is provided on one side of the riveting station 4a. The riveting station 4a, the jacking station 4b and the discharging station 4c are all provided with a positioning die 5 that is rotatably connected with the turntable 4 . In this embodiment, the motor one 3 is connected with the turntable 4 through a cam divider, so that the turntable 4 ro...

Embodiment 2

[0069] The structure and principle of this second embodiment are basically the same as that of the first embodiment, except that the driving mechanism includes telescopic cylinders 2 and a connecting frame 32 in the shape of a "concave" that are all located on the lower side of the turntable 4, telescopic cylinders 2 and The quantity of connecting frame 32 is all the same with the top cover 6 and the positions correspond one by one.

Embodiment 3

[0071] The structure and principle of the third embodiment are basically the same as those of the first embodiment, except that the position-limiting structure includes the bottom wall of the top sleeve 6 and the top wall of the turntable 4, and the bottom wall of the top sleeve 6 presses against the top wall of the turntable 4 .

Abstract

The invention provides a rivet pressing mechanism of a motor core pressing riveting device, which belongs to the technical field of machinery. It solves the problem of poor efficiency of existing riveting machines. The rivet pressing mechanism of the motor iron core riveting device includes a bracket, a beating mechanism, two clamping blocks arranged side by side, and a single-acting cylinder 1 that drives the two clamping blocks to approach each other. The strip hole is opened on one side of the strip hole, and the upper end of the strip hole is a tapered hole that becomes smaller in the radial direction. The support is provided with a feeding mechanism that can send the rivet rod into the strip hole through the opening, and the rivet head The part moves down under the action of gravity and presses on the wall of the taper hole 1. The beating mechanism includes a push rod vertically arranged directly above the taper hole 1 and a driving member 2 for driving the push rod to move up and down. The rivet pressing mechanism of the iron core pressing device of the electric motor has high efficiency.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a motor core riveting device, in particular to a rivet pressing mechanism of the motor core riveting device. Background technique [0002] The stator core or rotor core of the motor is made of stacked silicon steel sheets. In order to ensure that the silicon steel sheets are closely matched and not loose, multiple rivets need to be further pierced after being pressed into blocks. [0003] Existing equipment for pressing rivets, such as a motor stator core two-station automatic riveting machine [Application No.: 201510912410.8] disclosed in the Chinese patent library, includes a workbench, and an upper mold mounting plate is fixedly connected to the top of the workbench, and also includes The rotary table is connected with a rotating mechanism under the center of the rotary table. The two ends of the rotary table are the pressing part and the returning part respectively. The press...
