Description

Technical Field

[0001] This utility model belongs to the field of press-fitting machines, specifically, it relates to a horizontal press-fitting machine for motor stator cores. Background Technology

[0002] The stator core of a motor is an important component of a motor, and it is usually made of multiple layers of silicon steel sheets. A horizontal press machine is a hydraulic mechanical device mainly used to press and shape objects. The stator core of a motor needs to be pressed and fitted using a horizontal press machine during processing.

[0003] Chinese patent application CN201720301521.X discloses a large-scale horizontal press-fitting machine for motor stator cores, comprising a fixed housing and an operating housing mounted on top of the fixed housing. The operating housing has an operating slot with an opening on the front. Inside the operating slot are a left bolt clamping mechanism for fixing the workpiece and a right bolt clamping mechanism for fixing an electro-hydraulic press. A control box with a built-in DC motor is fixedly connected to the upper part of the fixed housing, located on the left side of the operating housing. This utility model's large-scale horizontal press-fitting machine for motor stator cores utilizes an operating slot with a built-in bolt clamping mechanism inside the operating housing. The DC motor inside the control box drives a horizontal transmission rod to control the position of the bolt clamping mechanism. Furthermore, a telescopic rod inserted into a telescopic hole facilitates the loading and unloading of the bolt clamping mechanism. The operation is very simple, with low requirements for fastening and welding, and high precision.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this embodiment provides a horizontal press-fitting machine for motor stator cores, including a press-fitting table 1. An adjustable placement component 2 is fixedly installed on the top of the press-fitting table 1. A mounting frame 3 is fixedly installed on the top of the press-fitting table 1. A mounting groove is provided on the inner wall of the top of the mounting frame 3. The mounting groove has a limiting effect on the stable press-fitting component 4. The stable press-fitting component 4 is fixedly installed inside the mounting groove. A control panel 5 is installed on one side of the press-fitting table 1. A controller 6 is fixedly installed on the inner wall of the bottom of the press-fitting table 1. The controller 6 and the control panel 5 are electrically connected, which improves the intelligence of the horizontal press-fitting machine.

[0029] One application of this embodiment is as follows: The motor stator core parts that need to be press-fitted are placed on top of the adjustable placement assembly 2 by manual placement. The adjustable placement assembly 2 can place motor stator cores of different sizes and models. The controller 6 is operated by the control panel 5, which can control the stable pressing assembly 4, thereby enabling the press-fitting of the motor stator core. The stable pressing assembly 4 can detect the pressing pressure to avoid over-pressing and damaging the motor stator core. The control panel 5 can also display the CNC pressing process.

[0030] The adjustable placement assembly 2 includes a base 201 and a vertical plate 202. The bottom of the base 201 is fixedly installed on the top of the pressing table 1, and the bottom of the vertical plate 202 is fixedly installed on the top of the base 201. A rotating seat 203 is fixedly installed on one side of the vertical plate 202. The support frame 205 can rotate inside the rotating seat 203, which improves the stability of the support frame 205. The support frame 205 is installed inside the rotating seat 203. A spring 204 is fixed on one side of the vertical plate 202, and the other end of the spring 204 is fixedly installed on one side of the support frame 205. A buffer pad 206 is installed on the other side of the support frame 205. A groove is opened on the top of the base 201, and a sliding rod 207 is fixed inside the groove. The sliding rod 207 has a limiting and guiding function for the moving part 208. The moving part 208 is slidably installed on the outside of the sliding rod 207, and a pressing plate 209 is fixed on the top of the moving part 208.

[0031] In this embodiment, the motor stator core parts to be processed are manually placed between two support frames 205. The top of the buffer pad 206 contacts the motor stator core parts, providing a certain buffering effect. The motor stator core parts will compress the support frame 205, causing the spring 204 to compress. At the same time, the support frame 205 can rotate inside the rotating seat 203, which is convenient for placing motor stator core parts of different sizes. It is highly practical. When pressing the motor stator core parts, the stable pressing assembly 4 can drive the moving part 208 to slide outside the slide rod 207. The pressing plate 209 can move with the moving part 208, thereby enabling the pressing process of the motor stator core.

[0032] The stable pressing assembly 4 includes a servo motor 401 and a bidirectional screw 402. The servo motor 401 is fixedly installed inside one side of the mounting groove. One end of the bidirectional screw 402 is installed at the output end of the servo motor 401, and a bearing seat is rotatably installed at the other end of the bidirectional screw 402. The other side of the bearing seat is fixed inside the mounting groove. The bearing seat has a fixing effect on the other end of the bidirectional screw 402, which improves the stability of the bidirectional screw 402 when rotating. A slider 403 is slidably installed on the outside of the bidirectional screw 402. The slider 403 is threadedly connected to the bidirectional screw 402. The slider 403 is located inside the mounting groove. A pressing frame 404 is fixedly installed at the bottom of the slider 403. A slide rail 407 is fixedly installed on the top of the pressing table 1. A moving block 408 is slidably installed inside the slide rail 407. The bottom of the pressing frame 404 is fixedly installed on the top of the moving block 408. A pressing seat 405 is fixedly installed on one side of the pressing frame 404, and a pressure sensor 406 is installed on the other side of the pressing seat 405.

[0033] In this embodiment, the servo motor 401 drives the bidirectional screw 402 to rotate. The slider 403 contacts the inner side walls of the mounting groove on both sides. The mounting groove has a limiting effect on the slider 403, allowing the slider 403 to move on the bidirectional screw 402 instead of rotating, which facilitates the movement of the pressing frame 404. The pressing base 405 and the pressure sensor 406 can move with the pressing frame 404, thereby pressing the motor stator core. The pressure sensor 406 can detect the pressure to prevent over-pressing and damage to the motor stator core. The pressing frame 404 connects the slider 403 and the moving block 408 together. While the pressing frame 404 moves, the moving block 408 slides inside the slide rail 407, improving the stability of the pressing frame 404's movement.
