Description

Technical Field

[0001] This utility model relates to the field of electric drive power assembly technology, specifically a novel valve body press-fitting device. Background Technology

[0002] In modern industrial production, valve body press-fitting is a crucial step in many mechanical manufacturing fields. Traditional valve body press-fitting devices typically employ simple mechanical press-fitting methods, applying pressure directly to the valve body through a press head. However, for some valve bodies that are small in size and have thin walls, especially those requiring reversible pressing and with minimal dimensional differences between the two sides, traditional press-fitting methods present numerous problems.

[0003] like Figure 7 The valve body shown is small in size and has a very thin wall, but it requires precise orientation during press-fitting. Ordinary press heads struggle to accurately identify the valve body's orientation, leading to incorrect orientation and press-fitting failure. Furthermore, the lack of precise control and protection measures during press-fitting makes the valve body easily damaged, affecting press-fitting accuracy and product quality. These problems not only reduce production efficiency but also increase production costs, hindering the development of related industries. Utility Model Content

[0004] The purpose of this utility model is to provide a novel valve body pressing device to solve the problems mentioned in the background art, such as the difficulty of accurately identifying the positive and negative directions of valve bodies with small size and thin wall thickness but requiring correct orientation during pressing, leading to incorrect valve body orientation and pressing failure; and the problem that the lack of precise control and protection measures for the valve body during the pressing process can easily damage the valve body, affecting pressing accuracy and product quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel valve body press-fitting device includes a press-fitting base and a press-fitting power mechanism and a press-fitting frame disposed on its top surface.

Rotating shafts extending outward are provided on both sides of the cylindrical rotating block and are connected to the shaft bracket provided on the positioning seat of the pressing frame through bearing seats. A rotating drive rod is provided on one of the rotating shafts. The rotating drive rod is hinged to the piston shaft of the rotating cylinder. The tail end of the rotating cylinder is hinged to the cylinder fixing seat provided on the pressing main frame.

[0006] Preferably, the press-fitting drive unit is a servo press or a press-fitting cylinder.

[0007] Preferably, a return spring is sleeved on the outer side of the telescopic shaft of the press-fitting drive unit; the return spring is placed between the sliding connecting frame and the press-fitting main frame.

[0008] Preferably, the pressing frame positioning seat is disposed on the guide rail slide, and the top end of the valve body feeding channel is connected to the valve body feeding mechanism.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model adopts automatic valve body rotation technology. Through the valve body rotation structure set in the middle of the press-fitting channel, the valve body can be rotated precisely, basically ensuring 100% correct orientation of the valve body. The application of this technology effectively solves the problem that traditional press-fitting devices cannot accurately identify the orientation of the valve body, greatly improving the accuracy and reliability of press-fitting.

[0013] 2. During the press-fitting process, this utility model utilizes a return spring sleeved on the outer side of the telescopic shaft of the press-fitting drive unit, and a valve body rotation channel on the press-fitting main frame to buffer and protect the valve body. Simultaneously, the rotation angle of the valve body rotation channel is precisely controlled at 90 degrees, ensuring the stability and consistency of the valve body during press-fitting.

A press-fitting power mechanism 2 for providing press-fitting power for valve body press-fitting is provided on the top surface of the press-fitting base 1 near its side. A press-fitting frame 3 for assisting in press-fitting the valve body to the housing is provided on the front side of the press-fitting power mechanism 2. A rotating structure 4 for rotating the valve body by ninety degrees is provided on the press-fitting frame 3.

[0026] The top surface of the press-fit base 1 is provided with a press-fit power bracket 11 and a guide rail slide 12; the press-fit power bracket 11 is provided with a press-fit power mechanism 2; and the guide rail slide 12 is provided with a press-fit frame 3.

[0027] The press-fitting power mechanism 2 includes a press-fitting drive unit 21 mounted on the press-fitting power support 11. The press-fitting drive unit 21 is a servo press or a press-fitting cylinder. The front end of the telescopic shaft of the servo press or press-fitting cylinder is provided with a sliding connecting frame 22. The sliding connecting frame 22 is mounted on the guide rail slide 12 by a slider and can move along its axial direction. On the other side of the sliding connecting frame 22, a press-fitting shaft 23 is provided, which is coaxial with the telescopic shaft of the press-fitting drive unit 21, and a return spring 24 is sleeved on its outer side. The front end of the press-fitting shaft 23 is provided with a pressure head 25.

[0028] The pressing frame 3 includes a pressing frame positioning seat 31 disposed on the guide rail slide 12. A pressing main frame 32 is disposed on the pressing frame positioning seat 31. A pressing channel 33 is horizontally disposed on the pressing main frame 32 at a position corresponding to the pressing shaft 23. A cylindrical rotating cavity 34 is disposed in the middle of the pressing channel 33 and a valve body rotating structure 4 is disposed thereon. A housing mounting position 35 is disposed on the outer side of the front opening of the pressing channel 33 and a housing is fixed thereon. A valve body feeding channel 36 is vertically disposed above the rotating cavity 34 and communicates with it. The top end of the valve body feeding channel 36 is connected to the valve body feeding mechanism. The valve body feeding mechanism feeds the valve bodies to be pressed one by one into the rotating cavity 34 through the valve body feeding channel 36.

[0029] The valve body rotation structure 4 includes a cylindrical rotating block 41 disposed in the rotating cavity 34. A valve body rotation channel 42 is radially provided through the middle position of the cylindrical rotating block 41.

[0031] When using, such as Figure 7The valve body shown has a small difference in length and width, so it is difficult to accurately control the direction of the valve body using a traditional press-fitting mechanism. However, the valve body feeding channel 36 of this utility model is vertically set. Because the tail end is heavier, the valve body will automatically switch to a head-down position in the valve body feeding channel 36 and enter the valve body rotation channel 42. Then, the valve body rotation structure 4 drives the valve body to rotate 90 degrees, so that the valve body can be accurately press-fitted into the housing.
